MACHINE FOR TURNING, BORING,1&o.

T Specification of Letters Patent No. 7,977, dated March 11 1851.

To all whom it may coneem Be it knownthatwe, MARTIN WAY and THOMAS R. WAY, of Paintersville, int-he county of Greenland State of Ohio, have inyented a newandwuseful Machine for Bendln'g, Drilllng Borlng, andfTurning Wood had to the accompanying drawing, which forms part which-- r a r r yFigurejl represents a view in perspective ofour improvedmachine. Fig. 2 is a front elevation of the same, and Fig. 3 is a transverse section at thelinew m ofFig. 1. r r

Ourniachine is constructed tobend metals to curves'of any required radius, and tobore,

drill, and turn bothwood and metals.

It is particularly applicable to the business of carriage-making as it embodies in a single machine the means of effecting many of those mechanical. operations which are re quired in constructing wheelcarriages, and which have heretofore been effected in separate machines. r l n i The various moving portions ofour machine are mounted upon twostrong frames or bedsA, B, which cross each other at right anglesin theform of'a T and are firmly bolted togethen The upperedges of the side pieces of each frame are A shaped to support and guide the various carriages which are required for different kinds of work. A standard G sliding vertically in dove-tailed grooves is fitted to the front of the machine at its middle, and a corresponding shorter sliding standard c is fitted to the oppositeside piece of thebed These standards areeach raised and depressed in an equal degreeby means of a screw (4 which turns in a lug projected from the side piece of the bed, and whose threads engage in a female screw cut in a lug b projectedfrom the standard above it. The head of each screw is fitted with a pinion c, the two being of equal size and both gearing into an intermediate wheel cl, so that whenfione screw is turned to raise or depress one standard the other screw is turned with equal velocity to move the other standard equally in thesame direction. Thescrew a at the front of the machine is fitted with a hand wheel 6 by means of which it may be turned with facility and a scale D is secured to the side piece of the machine to show the distance to ofthis specification and in which the standards are to be raisediii bend? ing metals of various thicknesses. The standards G, C,support aroller E which crosses the bed A, its gudgeons being supported in boxes inthe standards. Thegudgeons at each end of the roller are prolonged beyond the standards. The prolonged ex} tremit-y at the front of the machineis fitted i ;with a cog wheel F and with apinion g.

The cog-wheel gears intoqa pinion f whose shaftis supported by the standard C and is Two carriages J J are mo-untedupon the A shaped edges of the bed A. These each'supi port a roller E and are moved in. an squat degree to and from the ceiiterroller E by means of a rightand left screw j which acts upon nuts fixed to each carriage. 1 The head of this screw is. fitted with a hand wheel by means of whichit can be turned with facility to set the rollers E at any desired distance from the middle roller E. A scale K] is at tached to one of the sidepieces of the bed by means of which the curvature or any piece of metal which isbent by passing it under the centerroller andoveithe two lateral ones, is shown by the position of the carriage with respect tothe divisions of the scale. p r a A movable headstock I is mounted upon a saddle L whieh: is secured by means of clamp screw 70 to a carriage Mwhich lscon structed toslide to and fro uponthe A'edges of the side pieces ofthebed BL Aninten mediate sliding carriage N is also con st-ructed to slide upon this bed and is moved to and fro by means of a pair of feed screws m, m, which act upon a pair of nuts a, a, secured to the opposlte sides of the carnage.

These screws are prevented from moving endwise'by collars o, andtheir heads are fitted with aspair of equal cog-wheels P P whose {teeth engage with those of the pinion g on the roller E. This sliding carriage supports a pair of tool holdersRRwhich are also used to clamp any piece of wood or metal which is to be drilled or bored. The tool:

holdersheach consist of an upright frame with two sliding blocks 79 p which are moved up and down at will by screws r-r. They are made fastby a crossbar O and clamp screw 9 to a disk S which turns upon a lower disk S; the latter is constructed to slide transversely upon shaped guides t t; the tool holders are also constructed to slide toward or from each other on guides 8 secured to the upper disk S; and the arrangement of the various moving parts thus described is such that the clamp-screw q not only secures the tool holders R R to the disk S on which they stand, but also secures this disk to the lower one and makes fast the latter to the carriage. The lower disk with the various devices mounted upon it is moved to and fro on the carriage by means of a screw u to whose head a hand wheel is fitted. An adjustable scale T is fitted to one of the side pieces of the bed, by means of which the distance to which the carriage N is moved, is shown.

When the machine is used for turning, a face plate U or a chuck is fitted to the shaft H of the stationary head stock; when used for boring a boring bar is inserted between the stationary and movable head-stocks; when the drilling is to be done the drills are fitted to a socket in the end of the mandril.

When iron, such as wheel tire for example is to be bent with this machine, the carriages J J are moved by the screw j to such a distance from the center roller as is shown by the scale K to be the proper one for giving the required cuvature to the tire, the center roller is then raised by raising the standards by means of their screws or at until the bar can be passed over the side rollers and beneath the center roller E, which is then depressed upon the bar by the action of the screws a and is turned by applying the hand to the crank Gr. The turning of the roller, whose barrel is roughened, carries the iron to and fro between theunder side of the upper roller and the upper sides of the lat-- eral roller. As the bar is bent, the central roller is gradually depressed until it arrives at the lowest position required to give the bar the proper curve; this lowest position varies with the thickness of the bar and is shown for each thickness vof iron by the scale D.

dril and be bored by a stationary drill se cured to the tool holder and advanced against the article.

If a hub is to be bored to receive the boxes, it is clamped between the tool holders and is fed by the action of the feed screws m against a boring bit secured to a boring bar inserted through the hub between the movable and stationary head-stocks; the boring bar is driven by a pin '0 in the face plate V, and the distance to which the bit enters the wood is shown at any moment by the scale T.

When the machine is used for turning, the tools are secured in the tool holders R R, which may be'placed in any required position to suit the work.

hat we claim in the foregoing as our invention and desire to secure by Letters Patent is- I The tool and block holder herein described consisting of two upright frames capable of movement toward each other and of being clamped at a greater or less distance apart as may be required to adapt them to holding blocks of different sizes and tools of different lengths or forms, each frame being provided with upright parallel guides carrying adjustable jaws for holding boring or turning tools at different heights and angles and to aid in holding blocks of irregular forms; these frames being mounted upon a carriage capable of being turned or moved right or left so as to hold the tool or present the substance to be bored in the required position, substantially as herein set forth.

In testimony whereof we have hereunto subscribed our names.

MARTIN WAY. THOMAS R. VAY.
