To all whom it may concern.-

Be it known that I, CHARLES F. PEASE, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Box-SettingUp Machines, which are fully set forth in the following specification, reference being had to the accompanying drawings, forming apart hereof, and in which Figure 1 shows a side view of myimproved paper-box setting-up machine, taken on its right-hand side and without the near side of the frame, so as to show the machinery more plainly, and in which the wheels a I) Z) only show by their pitch-circles in broken lines. Fig. 2 shows a front elevation of the same, in

which only the nearer parts of the machinery are shown. Fig. 3 shows a plan view of the top of the machine; and Fig. 4 shows a plan view of the machine under the table, the latter, with all its machinery above it, being removed and the legse shown in cross-section Fig. 5 shows in side view a pair of my gearwheels for producing intermittent motion. Fig. 6 shows in side view the wheels I) Z), pro vided with the plates 70 k in which the wheel I) is in the last part of its motion and about being locked into the position of rest. Fig. 7 shows" the same parts and view as Fig. 6, but at the point at which the wheel I) is at the end of its rest and just at the point of means of which said operations are performed. Fig. 11 shows the body of a box with its bottom and sides in perspective, provided with inturned flanges .9, ready to have its ends put on by my machine.

Like letters refer to like parts of the drawings.

The object of my invention is to produce a setting-up machine for paper boxes in which said operation shall be done entirely by automatic machinery and in a more economical and expeditious manner than has been heretofore' accomplished, and to attain said ends I construct my improved device substantially as follows, namely:

Between suitable side frames A, and upon bearings therein connected together by suitable eross-bars and a table or top plate A are mounted the shafts B B B B of which E is the driving-shaft, provided with a pulley and belt receiving power from some motor moving in the direction of the arrow, as shown in Fig. 1. On said shaft is a pinion a, meshing with a gear-wheel a above it, (said gearwheel a and pinion a are indicated by their pitch-circles in Fig. 1,) and on said shaft B is also keyed a gear-wheel I), provided in the present instance with sixty-two teeth, which meshes into a pair of gear-wheels b b on the shaft B moving closely side by side on the same shaft, of which one I) is keyed to the shaft and the other runs loose thereon. The combined length of the teeth of said gears is equal to that of the teeth 011 the wheel I), but one of them (7)" in this case) requiring greater strength has the longest teeth.

Upon the shaft 13 is mounted an oval gearwheel 0, which meshes into a corresponding oval gear-wheel c on the shaft B". Said shaft B is a crank-shaft having a crank (l midway between the side frames A, with its crank d shown at the end of its downstroke. A pitman-rod d. connects said crank to a cross bar (1 to the ends of which are secured the vertical rods (1, sliding freely in guides (1*, attached to the outer sides of the frames A, and which project beyond the top of the table, where they are adjustably connected by a strong head or follower d (Shown pressing upon the table A The center of said follower is vertically over the center of the shaft B and said shaft is held and revolves in the lower end of a pair of pillars or legs 6, uniting together upon their inner sides, so as to form an arch above the lower side of the endless chain 0. It will be observed that while said pillars e form the support for the shaft B they and the pitman-rod also form the resisting medium, through thrust or pressure, against the strain of the rods (Z and Too j, attached to a shaft B through them against the pressure of the follower (1, the said pillars pressing upward against the under side of the table as the follower (1 presses down upon it. The revolution of the crank (1' therefore raises and lowers the follower d, and by means of the oval gear-wheels c and c, with a gradually but rapidly increasing motion to the end of its upward stroke and conversely a rapidly-decreasing motion on its downward stroke, with proportionally increased power of pressure at the moment the platen or follower is on or near the table, which is one object accomplished by means of such oval gear. Another object is to make room as early as possible for the mechanism which distributes and imprints the paste upon the box ends. The said latter mechanism consists of a paste-trough g and a second follower h, attached to two rearward-projecting arms (1 of the-follower d, in which it is held by vertical rods sliding through holes in said arms. The force of pressure of said follower 7L is governed by a coiled spring (1*, wound around the rods (1 between the said arms 0' and top of the fol lower 71, and the extent of its downward motion is controlled by a toe d" at the upper end of said rod above the arm (1. Said toe extends over a wiper i, attached to a shaft 1'', lying on the arms (1, and it is turned by means of a lever i into the position shown by the dotted outlineof said lever. By means of said construction the said follower may be raised out of contact with the box ends upon which it imprint-s the paste.

The follower h is supplied with paste by means of a reciprocating trough g, extending across the table A and of which the bottom is raised sufficiently above to clearany thick ness of box ends safely which may pass over the table under it. Said trough is provided at its ends with lugs q, to which are bolted armed sliding piecesg-, having either grooves, as here shown, or rollers upon their inner sides which run over the longitudinal edges of the table A which form tracks upon which said sliding pieces move and carry the trough g. Said armed sliding pieces 9 have at the lower end of their arms a pin carrying one end of a connecting-rod, of which the other end is connected to the crank-pin of a crank Said parts-the armed sliding piece, connecting'rod, and cranksare attached to each end of said pastetrough g and shaft B", and the throw of said crank is great enough to pass the roller g, which distributes the paste clear to the forward edge of said follower 7t. The second point in the utility of the oval gear-wheels is now apparent, since by means of it the follower 71 is quickly raised, so that the trough 9 may pass under it. The long arms to the pieces 9 are not indispensable, but are simply for the purpose of giving long enough connecting-rods in this case. From what has preceded, it is, however, evident that with the reciprocating motion of the follower h the motion of the trough 1 cannot also be continuously reciprocating, but must also be intermittent, and to attain said end the gear-wheels l) b, with other connecting parts now to be described, or their equivalents, are necessary. The driving-wheel I) is the smallest, and has in this case sixty-two teeth meshing with the wheel I), which has about seventy-two teeth; but it has a blank space by leaving out four or five teeth from their base, thus leaving only sixty-eight teeth in said wheel. \Vhen the center of said blank space is on a line connecting the axes of the shafts of said wheels, the teeth of the wheel I) will pass freely through said space, until by some means the wheel 1) is moved far enough to cause their teeth to engage. This is accomplished, and said wheel b caused to alternately stop and revolve for each revolution of the wheel I), by the following-described mechanism, namely: Upon one side of the wheel I) is bolted a plate 7.: of the same diameter as the pitch-circle of said wheel, with a spur or tooth 7t projectin g as far as or beyond the teeth of said wheel, and on each side of said spur is cut a notch 7.3 and on the wheel I) is bolted aplate of which its outer edge is a concave are It, of the same radius as that of the plate 7t, and of which the center of its are is on the pitchcircle. The length of said are should cover about eight or ten teeth of the wheel Z), and it should lap equal distances over the center of said blank in the wheel I). hen said wheels are moving in gear, as shown in Fig. 5, the spur 76' will at one time pass in front of the plate W, and the outer corners of the plate It will pass intothe notch irfflbehind the spur 7a, which will then pass onward until the are of said plate rests upon the circumferential face of the plate It, and the said are and plate slide upon each other, the moving wheel I) thus holding the wheel 11 at rest until near the end of its next revolution, when the spur It will strike against the rear edge of the plate It", and thus push the wheel I) onward and again cause the teeth of the wheels to interloek, and thereby the wheel I) again revolves one revolution, as before described, and so on alternately. In this case the rear edge of the plate 763 and outer corner of its are find clearance in the notch k in front of the spur It, as shown in Fig. '7. Thus while the wheel (1 makes continuous revolutions the wheel I), actuating the oval gears, makes with them only one revolution and the follower (1 one complete motion only at every alternate revolution of the wheel I), and the said wheels and parts are so adjusted together as to leave said followers up and at rest at the highest point of their motion. The reciprocating motion of the trough g is obtained by a precisely similar arrangement of a plate 70 on the opposite side of the wheel Z2, and a loose wheel 11 on the opposite side of the wheel I), and contrived in every other Way like it, except that it runsloose on the shaft and has shorter teeth, because it has less resistance to overcome. Said wheel I) is provided with a hub or sleeve turning with it, provided on its outer end with a sprocket-wheel Z, upon which runs a link-belt Z over an equal diametersprocket- 5 wheel Z attached to the shaft 13.

By arranging the wheel 12 so that it will begin to move at or near the time when the wheel I) is at or near the point of coming to rest the trough 9 can be made to pass under, I and, by means of its roller g ,be caused to distribute paste' against the under surface'of the follower 72, or on any kind of type or device -arranged for such purpose, and to pass back out of the way and to rest until the pasted I follower can descend and discharge or imprint its paste upon abox end placed under it. The mechanism for manipulating the box ends in connection with the previously-de- "scribed mechanism is constructed and oper- 2o ates as follows with it.

Upon the rear end of the table A are two laterally-adjustable sheet-metal wallsm, eachof which is bent inward at right angles, so as to form a short wall m; Said wall is attached 5 lug into a channel cut across the table, in which plays a right and left hand screw m which passes through said lugs, which are threaded on the said screw. By means of this arrangement the walls mxmay be set so as to hold various-sized box ends between them.

On the inner side of the walls m, and parallel to, and of about the width of, the front m, are set adjustable walls, which are held by rods an, attached to their rear sides, and which pass through blocks on, provided each with a set-screw, whereby said walls may be adjusted back and forth, and held at any desired point. By means of this arrangement square box ends are held at their four corners when piled between said walls, and said box ends are pushed out from under the pile w by means of a pusher, which consists of a block a, reciprocating back and forth in a longitudinal slot out midway between the edges through the rear end of the table A To the under side of said block is attached a lug n, and to it is attached one end of a connecting-rod n of which the other end is attached to a crank 12 on one end of the shaft The end of the connecting-rod which is 011 the crank is slotted, and the crank-pin plays in said slot during a partof its motion. By this arrangement the motion of the block at is kept within desired limits.

Upon the block n is attached a plate, which has a longitudinal slot 01 through which projects a bolt and thumb-nut n. By means of to this construction the plate 01 may be adjusted to the width of the box ends LU, so that all sizes may be pushed forward acertain desired distance, so as to be received in the clips or nippers o of the chain 0, which runs in the same slot in which the block a plays, and extends from near the wall m to the front end of the table beyond the follower (Z and of to a base m and from said base descends a which the upper surface of its links are even with the surface of the table A Said chain runs over two six-sided drums 0' on the shafts B B and is actuated in the direction indicated by the arrows by means of the chain belt Z and intermittent gear-wheel 19 whose operation has already been described. 'The links of the said chain are connected by means of rule-joints, and the length of each link is of course adjusted to the sides of the drums 0'. Upon the said chain 0, at intervals (five in all in this case) adapted to the position and motion of the other parts, are attached spring-clips 0 which press down on the surface of the links, and form,with them, nippers, which catch the single ends as they are pushed forward into them from under the walls m by the pusheror blade 12 from under the pile After the said ends are securely caught under said spring 0 they move forward with the chain and come to rest each successively under the follower h, where they receive or are imprinted with the charge of paste on the follower, and at the next interval of motion -move under the follower 01 where they are released by another adjustable cam 0 placed and operating, as shown, for the purpose of releasing the said box ends'where they are attachedto the ends of the boxes, which said boxes are formed of onlya bottom and longitudinal sides bent in the desired shape, and of which a narrow and parallel-sided strip of said bottom and sides is bent inward at right angles so as to form surfaces upon which the now pasted box end is pressed by holding the box with its bottom against the front face of the follower (Z and so that the inturned flanges 8, above spoken of, are in contact with the bottom of said follower. When, now, the follower descends, it brings the outer surface of said inturned flanges of the box in contact with the pasted box-end and presses the two firmly and securely together. The said spring or clip 0 is opened at the right point by means of an adjustable cam 0 over which it slides, and is thereby raised by push-bar 0 which plays freely through a slot in the same link to which the spring is attached, and is either fastened to said spring or has, as here shown, a flat head to keep it from falling through the link.

The moving mechanism of the chain 0 is so adjusted that the chain comes to rest at the point where the pusher is 011 top of the cam, so as to hold the spring open, while during said period of rest the pusher n pushes one of the box ends from under the pile 00 under it, and at about the same time a like cam under the follower d releases said box end again from the said nippers, which is then attached to a box end, as already described.

To counteract the great weight of the follower 61 and its attached parts, a lever r, with an adjustable weight 1", fulcrunied at T is placed under the cross-bar (P.

The large roller g in the trough g has on each of its sides a smaller roller, as shown,

and said rollers are turned by means of gearwheels 11, working on a rack '11 attached to the outer edge of the table on one side.
