To all whom it may concern.-

Be it known that I, J osmn J. PHILBRICK, a citizen of the United States, residing at Mobile, in the county of Mobile and State of Alabama, have invented certain new and useful Improvements in Machines for Manu facturing BarrelStaves, which are fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of a stave-machine embodying my invention; Fig. 2, a plan view of a finished stave; Fig. 3, a sectional view of the same on the line 5 5 of Fig. 2; Fig. 4, aside elevation of the planer; Fig. 5, a sectional view of the same on the line 6 6 of Fig. 4; Fig. 6, asectional view on the line7 7 of Fig. 5; Fig. 7, a sectional view of the crozing and chamfering machine on the line 8 8 of Fig. 1; Fig. 8, a similar section taken on the line 9 9 of Fig. 1.

Like letters refer to like parts -in all the figures.

My invention relates to machines for manufacturing barrel-staves, and is in the nature of an improvement on the machine set forth in Letters Patent No. 184,751, granted to Alexander C. Blount, November 28, 1876; and it consists in certain improvements in the crozing and chamfering mechanism, whereby not only a more effective machine for that purpose is produced, but the said machine is also better adapted for use, in combination with a stave planer and stave-jointer, to produce a complete machine, by which all the various steps may be performed which are necessary for the manufacture of a complete stave.

To these ends my invention consists in certain novel features, which I will now proceed to describe, and then specifically point out in the claims.

The complete machine consists, essentially, of three membersa planer, A, in which the blanks are so planed as to have a convex upper and a concave lower surface; a chainfering, crozing, and stamping mechanism, A, in which these several operations are performed, and a jointer, A", in which the edges of the stave are shaped to complete it.

The particular planer and jointer form no part of my present invention, they being described and claimed in two separate applications filed by me October 20, 1884, and numbered, respectively, 146,134 and 146,135, my present invention relating to the construction and arrangement of the crozing and chamfering mechanism and to its combination with the other parts of the complete machine.

The planer A is shown as consisting of a frame of ordinary construction, provided with a central longitudinal bed, B, which forms the way or path upon which the stave travels. Feed-rollers C C C C are arranged in pairs above and below the way B, to carry the stave through the machine. These feed-rollers are connected by suitable gearing, and actuated by means of a sprocket-chain, c, passing over sprocket-wheels connected in any suitable manner with the feedroller shaft, and also over a sprocket-wheel, C mounted loosely on the main driving-shaft of the planer.

C indicates a sliding clutch splined on the main shaft and adapted to engage with the hub of the sprocketwheel C the said clutch being actuated by means of a hand-lever,E, pivoted at e on a suitable support. By engaging the clutch C with the sprocket-wheel C motion is communicated with the feed-rollers, and by disengaging the said clutch the feedrollers are stopped.

The planers F F are arranged as shown in Fig. 6 of the drawings, the first planer, F, being provided with convex knives f, attached to the block or head F", and being arranged below the path of the stave, so as to give to the under side thereof a convex shape. The

' l'aner F is arran ed in the rear of the laner F, being provided with concave knives and arranged above the path of the stave, so as to 'give the upper side of the stave a convex shape. These planers are arranged to rotate in opposite directions, so that they will both out against the direction of the feed. The planers are mounted on shafts D, provided with pulleys, by which they are driven, the said shafts being arranged to rotate in bearings G, connected by means of hinged or knuckle-joints g to vertical sliding pieces G, arranged in suitable Ways on the frame of the planer. The lower ends of these slides rest upon suitable cams,Gr G attached to opposite ends of the transverse shafts B, so that by rotating one of the shafts B the corresponding slides, G, will be raised or lowered, thus si- Adjusting-screws g are interposed between multaneously and equally raising or lowering the bearings G and thereby the cutter-shaft and cutter. The cams G are provided with worm-segments which mesh with worms 12, mounted in the frame of theplaner, said worms being provided with wrench-grasps or other devices for rotating them to actuate the cams.

the lower ends of the slides G. and the cams G Githeirheads resting upon the cams, so that by screwing the said adj listing-screws up or down the slides to which they are attached will be raised or lowered independently, in order to properly level up the cutter-shaft, which is mounted upon the said slides. Slots a are formed in the slides, and through said slots pass clampscrews B,takinginto the frame of the machine,whereby the said slides may be clamped at any point after being adjusted by the mechanismjust described.

The stave-blanl ,which is a rectangular piece shaped to approximate the size desired for the finished stave, is fed in upon the bed B and carried by the various feed-rollers through the machine, being operated upon. by the planers F F, so that when it leaves the machine its lower side is concave in form and its upper side convex.

From the planer A the stave passes into the machine A, where it is chamfered, crozed,

and stamped with the number of staves to the barrel.

The chamfering, crozing, and stamping machineis shown in detail in Figs. 7 to 13 of the drawings, inclusive, and consists of a suitableframing provided with a bed or Way, B, upon which the stave travels, and above which, at about the center of the machine, is located a traction-wheel, H, mounted ona shaft, H, a d 'provided at its periphery with any suitabl roughening device to enable it to have sufficient frictional contact with the stave.

1? indicates a pin arranged in the path of the stave and adj ustably attached to the wheel pin adjustably to the wheel. On the shaft H is located a gear-wheel, H, provided with blank-segments z z and a a arranged diametrically opposite each other, the remaining portions of its periphery being occupied by gearsegments' .2 and 0.

M indicates a gear-wh eel arranged above the gear wheel vH on the main shaft M, and capable of engagement with the gear-segments of the wheel H this gear M being continuously rotated while the machine is in operation by means of a belt from the power passing around the main driving-pulley m.

H indicates a projecting arm or lug arranged on one side of the traction-Wheel H, and 1 indicates a similar arm, attached, as shown in detail in Fig. 10, to a mutilated bevel-gear, I, attached to a longitudinal shaft, N, extending the wholelength of the machine. The bevelgear I is provided with a blank-segment, 1,1, and a gear-segmen t, 2,which latter is arranged to mesh,when in position,with'a bevel-gear,L, which is continuously rotated by means of a beVeLgear, L mounted upon the main shaft M and meshing with a bevel -gear, L attached. to the upper end of the shaft L, upon which the bevel-gear L is mounted.

. The longitudinal shaft N, which isintermit tently rotated by means of the mechanism just described,as will be hereinafter explained,opcrates both the mechanism for clamping the stave in position and stamping the same, and also the mechanism for raising and lowering thecutter-wheels which perform thechamfering and crozing; and as both of these sets of mechanism are duplicatedin the machine, I will describe only one set of each kind of mechanism, the same description being applicable to the other, which is identical in construction, but reversely arranged.

1 indicates a cam attached to the shaft N and provided with a recess, h, in which,when the cam is stationary, rests a roller, 13, attached to one end of the arm J, pivoted at h to asuitable support on the frame and having at its other end a counter balance or weight, W, which holds the roller '5 'in contact with the cam I It will be observed that the roller bears against the under side of the cam, so that this latter will force the arm and the attached clamp positively downward and hold the samepositively in that position. To this arm J is attached the clamp J, which holds the stave in position on the bed while it is being operated upon, and to this clamp is attached a die, g, which will impress upon the stave a number indicating the number of staves which go to make a barrel,this die being removable, so that it maybe changed to suit the particular stave on which the machine is operating.

At the end of the shaft N is located an eccentric, K, surrounded by a strap, K, and to this strap is pivoted at ka connecting-rod, J, the other end of which is pivoted at k to a suitable gate or slide, F moving in ways formed therefor in the frame of the machine. On this gate is mounted, as shown in Fig. 7,

IIO

one of the bearings O of the shaft D, which carries the cutterwheel, the bearings of the other end being mounted on a similar slide actuated by an eccentric located near the middle of the shaft N. The cutter-wheel L is provided at its periphery with three series of k nivesa series of chaml'ering-knives, m, a series of crozingknives, n, and a series of equalizing-knives. 2". L indicates guides arranged at the side of the machine to steady and direct the belts which operate the eutterwvheels. It will be observed that the gates F on which the inner ends of the shafts D are mounted, are provided with tubular sockets 7e, and a single pivot-bolt, k, is employed at this point, extending into the said sockets and being capa ble of longitudinal motion therein, to allow for the variation in distance between the gates which arises from their moving in lines not parallel. A single eccentric, K, and a single connectingrod, J, are employed to operate these two gates at the center of the machine, although it is of course obvious that separate eccentrics and connecting-rods may be employed to operate the inner gates.

Arranged at the rear end of the machine are a pair of feed-rollers, G, the one above and the other below the bed B, connected to each other by suitable gearing and driven by means of a belt, in. passing over a pulley, M, on the main shaft M It will be observed that the traction-wheel H has that portion of its periphery which is diametrically opposite the pin P somewhat flattened, as shown in Fig. 11, for the purpose hereinafterdescribed. This wheel is also provided with a stop pin, P in the path of which is arranged a spring, Q, attached to the frame of the machine.

The operation of this machine is as follows: The stave being fed in by the last set of feedrollers of the planer, as hereinbefore described, passes along the bed B until it comes in contact with the pin P, which is in the position shown in Fig. 11 of the drawings. \Vhen the stave strikes the pin P, it rotates the tractionwheel H and its shaft H and consequently the gear-wheel H whereby the gear-segment z therein is brought into engagement with the continuously rotating gearwheel M. The traction-wheel H is then positively rotated, and its roughened periphery engages with the surface of the stave and feeds the same along the bed B into the position in which it will be operated upon. During this operation the cutter-wheels are below the path of the stave, so as to offer no obstacle to its advancement, and the clamps J are raised for the same purpose. During this rotation of the tractionwheel H the lug or arm H therein comes in contact with the arm 1 on the bevel-wheel I, and thereby rotates the gear I sufficiently to bring the geared segment 2 thereof into engagement with the continuously-rotating pinion L, thereby rotating the shaft N to operate the clamping mechanism and raise the cutterwheels into operative position. At the same time that the arm H strikes the arm I the blank-segment a a. of the wheel is presented to the gear M, so that the latter ceases to act upon the former, thereby stopping the traction-wheel H with its flattened portion over the stave, which no longer advances. The rotation of the shaft N causes the cams I to act upon the arms J, to depress the clamps J, to hold the stave down on the bed, while at the same time the dies attached to the clamps impress upon the stave at each end thereof, as shown in Fig. 12 of the drawings, a number indicating the number ofstaves which are necessary to make a barrel. The rotation of the shaft N also operates the eccentrics K, and, through the connectingrods J, the gates F on which the bearings of the cutter-shafts are mounted, so as to raise the cutters and bring their knives into contact with the ends of the stave to perform their several operations, the stave being held in the meanwhile by the clamps J, as hereinbefore described. By the time these operations are completed the cams 1 having made a complete or almost complete revolution, return to the position shown in the drawings, the rollers i enter the recess h, the arms J being raised for this purpose by means of the weight \V, and at the same time raising the clamps J, the eccentrics K lower the out ter-wheels, and the arm 1 strikes the arm H, thereby rotating the traction-wheel shaft H and causing the blanksegment a a to pass from its position opposite the gear-wheel M, when the gearsegment 0 of the wheel H comes into mesh with the gear-wheel M. The traction-wheel H is now once more revolved, carrying the stave along the bed B until it is seized by the feed-rollers G and carried out of the machine. As the gear-segment 0 leaves the teeth of the wheel M the stave has passed from under the traction-wheel, the pin P comes in contact with the spring Q. and the tractionwheel is stopped in its original position,with the blank-segment z z of the wheel H presented to the driving-gear M and the pin P arranged in the path of the stave, as before. The rotation of the shaft N ceases when the arm I has come in contact with the arm H and started the traction-wheel anew,the blanksegment 1 1. of the bevel-gear I being then presented to the bevel-gear L, and the whole machine bcing ready to operate upon the next stave.

From the crozing, chamfering, and stamping machine A the stave passes into the jointing and shaping machine A. (Shown in detail in Figs let to 18 of the drawings.) This machine consists of a suitable framing provided with a longitudinal bed or way, 13, to support the stave. In suitable bearings in the frame are mounted the pairs of feed-rollers C O C" (7, driven by any suitable means. The central portion of the bed B is provided with knife-edged guides a", against which the stave is held by means of a pressure-roller, Q, loosely mounted on a shaft, Q resting in notched brackets Q and held down in place IiO by springs q, attachedto the frame and to the ends of the shaft, whereby a yielding pressure is obtained. The tension of these springs may be regulated by nuts g on the upper end of the bolts g, which connect the springs to the shaft Q.

Above the bed B, and between the front and rear sets of feed-rollers, is arranged atraction-wheel, R, secured to the shaft T, mounted as shown. The distance between the bed and the traction-wheel is such that when a stave is fed between them the serrated or toothed periphery of the wheel will engage with and be moved by the stave. In a suitable recess in the bed B is arranged the spring or detent' S, provided with a shoulder or stop, 8, to engage a pin or projection, p on the wheel R, and having an inclined projection, 8, arranged in the path of the stave. The traction-wheel is also provided with a pin, p arranged in the path of thestave immediately in front of the pinp; or a single projection of sufficient size to occupy the space of both pins may be used.

The traction-wheel may be provided, for the purpose hereinafter stated, with a gearsegment, 12?, arranged to mesh with a pinion, U, mounted on a shaft, U, having a pinion, u, meshing with the pinion u on the shaft of the feed-roller 0 In this case the traction-wheel will be grooved, as shown, to receive the segment, and the pinion U will be grooved to allow the pins 19 p to pass.

On the shaft T, and operated thereby, are mounted the adjustable wabble-wheels or cams Y, by means of which the cuttershaft-s and cutters are reciprocated. These wheels are secured on theshaft, as shown in detail in Fig. 16, the shaft being screw-threadedat tand grooved,as shown,and the wheel fitted loosely therein, the aperture through which the shaft passes being flaring at each end, to admit of tilting the wheel to any desired angle. while the wheel has a projection or spline, which enters the groove in the shaft to cause the wheel to rotatetherewith. Looselysurrounding the to the desired angle ofinclination to the axial line of the shaft.

The cutters WV are attached to the inner ends of shafts R, mounted in suitable boxes or slides, Sfiworking on the beds L, and retained in position by means of caps or strips r, at-

tached to the beds and projecting over the flanges d of the boxes or slides. In order to adjust the angle of the cutters and their shafts, the beds L are each pivoted at the inner end 7 at t to a cross-piece forming part of the frame,

the outer end resting on an adjustingscrew, X, working in the cross-piece. To secure the bed after adjustment, clamp-screws b pass through slots in the dependent arms of the bed and screw into the cross-piece to clamp the two in position. The cuttersare moved automatically to and from the bed B and the stave therein by means of the wabble-wheels Y, as before stated, the wheels Y passing between guides or projections on the slides 8*, these guides being shown in the present instance as anti-friction rollers M, mounted on a yoke or frame attached to the slides at or near their inner ends. The cutter-shafts are provided with suitable pulleys, by means of suitable belting applied to which the cutters are operated.

The operation of the machine is as follows: The beds N are adjusted to so incline the cutters as to give the proper bevel to the edges of the stave, and the wheels Y adjusted in their position and inclination to correspond to the width and shape of stave desired. The stave is then fed into the machine by the last feedrollers of the crozing and chamfering machine, as hereinbefore described, and, being seized by the feed-rollers 0 C is forcedonto the knifeguides 11 and held thereon by the pressureroller Q and afterward by the traction-wheel R, to prevent any wabbling or deviation from the proper line. The stave then strikes the inclined projection s, thereby lowering the spring S and its stop 8, thus freeing the traction-wheel B. At the same time the stave strikes the pin 1 of the wheel and causes the latter to revolve. The roughened periphery of thewheel engages with the stave, and the continuous advance of the latter, caused by the feed-rollers, creates a continuous rotation of the traction-Wheel and'shaft T, thereby causing the wabble-wheels Y to actuate the slides S and cutters W, so that the latter first recedeiand then advance, thereby giving the desired outline and bevel to the edge of the stave. The stave is then seized by the rear feed-rollers and carried out of the machine, while the pin 1) on the traction-wheel engages with the now freed stop 8 and stops the wheel and the mechanism operated thereby. When the traction'wheel'has been carried around the length of the stave, it may not have reached its normal position, as shown in the drawings;'but the pinion U, being in constant rotation, will be in mesh with the'segment n and will bring LII use, and stamped with a number indicating the number ofstaves ofthatparticular kind which go to make a barrel.

Heretofore in machines of this character, where all the various operations which go to complete the stave have been performed in one machlne, it has been found necessary to employ a crozing and chamfering machine in which the stave is fed through sidewise, and thereby interrupt the travel of the stave in order to change the direction of its feed; and to do this a special device and complicated mechanism of some kind have been employed. Moreover, in order to avoid the necessity of changing thedirection offeed ofthe stave twice, t has been found necessary to arrange the crozmg and chamfering mechanism at the end of the machine, so that its operations are the last ones performed on the stave. It has been found, however, that owing to the fact that the knives which do the crozing and chamfer- 1ng have to cut across the grain of the wood, they are liable to splinter and tear the stave at the polnt where they leave it, thereby greatly reducing the value of the finished article.

By the use of my improved chamfering and crozing machine, in which the stave is fed directly-through without any change of direction in the same path in which it passes through the planer and jointer, I am enabled not only to dispense with the mechanism which has heretofore been necessary in these combined machines for changing the direction of travel of the stave, but I am also able to arrangethe crozing mechanism in advance of the ointing mechanism, whereby thejointen knives, when they remove the surplus material at the edges of the stave, and more particularly at the ends thereof, will remove any portion thereof which may have been splintered or torn by the crozing or chamfering knives, as hereinbefore described, whereby the staves are delivered from the machine in a more perfect condition than heretofore.

As I have hereinbefore stated, I make no claim in the present application to the specific construction of the planer and jointer shown and described, the same being the subject of separate applications,as specified above. Any approved form of mechanism for these purposes may be employed in conjunction with my crozing and chamfering machine herein set forth; but I prefer to use the machines hereinbefore described. I do not wish to be understood as limiting myself strictly to the precise details of construction set forth in the description and shown in the drawings, as various mechanical modifications therein may be made without departing from the principle of my invention.
