WALTER S. lVINS, OF PHILADELPHIA, PENNSYLVANIA.

MACHINE FOR APPLYING HINGES T O BOX-LIDS.

SPECIFICATION forming part of Letters Patent No. 548,204, dated October 22, 1895.

. Application filed April 17, 1895- To all whom it may concern.-

Be it known that I, WALTER S. IVINS, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Machine for Applying Hinges to Box-Lids, of which the followingis aspecification.

The principal objects of my invention are, first, to provide a compact, durable, efficient, and comparatively simple machine for applying hinges to box-lids and the like, which shall be automatic in its action and require an attendant only to keep it supplied with lids and hinges, and, second, to so construct, arrange, and combine the parts of the machine as that they will compensate for slight irregularities in the sizes of the lids and may be adjusted for lids of different dimensions.

My invention consists of an automatic machine for applying hinges, having suitable barbs or projections to the respective members of box-lids, and, generally stated, it comprises a reciprocating hammer and a hingecarrier anvil for positioning the hinges and driving the barbs or projections thereof into the members of the box-lids, devices for feeding hinges to the hinge-carrier anvil, and means for feeding the respective parts of'the lid into position for receiving the hinges and for throwing them out of the machine with or without certain co-operating mechanism,

and as hereinafter more fully set forth and particularly claimed. The nature, characteristic features, and scope of my invention will be more fully understood from the following description, taken in connection with the accompaning draw ings, forming part hereof, and in which- Figure 1 is a side elevational view of a machine embodying features of my invention with the feet or legs thereof removed in order to permit of illustration on a comparatively large scale. Fig.2 is an end elevation of the same. Fig. 3 is a top or plan view of the machine. Fig. 4 is a sectional view taken on the line 4 4 of Fig. 3 and drawn to an enlarged scale.

Fig. 18 is asection taken on the line 18 18 of Fig. 17. Fig. 19 is a perspective view of a type of hinge adapted for use in connection with my improved machine, showing the parts of the same in position for receiving the parts of the lids of a box. Fig.

20 is a sectional view illustrating the position of the hinge shown in Fig. 19 after its application to the lids of a box. Figs. 21 to 25 are schematic views illustrative of the mode of operation of my machine, and Figs. 26 to 31 are views illustrating the various cams and their accessories shown at the lower portions of Figs. 1 and 2.

Referring to the drawings,.1 is the table, and 2 is the framework, of the machine. Actuating-power is applied, for example, by means of a pulley 3, attached to a main shaft 4, located near the bottom of the framework. From this main shaft the primary motions of the machine derive their movements. These primary motions are arbitrarily so designated because they are operated directly from the main shaft and are four in number, as follows: the hinge-carrier anvil, which receives the hinges, brings them into alignment with the table, and assists in driving their barbs or projections into the respective parts of the lid; the hammer, which co-operates with the hinge-carrier anvil in driving the barbs or projections of the hinges; the side-slide lidfeed, which feeds the respective parts of the lid along the table and into position for receiving the barbs or projections of the hinges, and the throw-out, which delivers the lids from the machine after the hinges have been applied.

The'hinge-carrier anvil comprises a yoke ICO 5, Fig. 28, afiorded a range of reciprocating motion in a vertical plane and operated in one direction by means of a cam 6, keyed or otherwise secured to the main shaft 4 and proportioned or designed for the production of the movements of this yoke, hereinafter described, and in the other direction by reason of its weight or under the influence of a spring or counterpoise. The vertical alignment of this yoke may be insured by providing it at its lower end with a notch for the reception of the main shaft 4 and by guiding the respective arms 7 and 8 of its upper end in suitable keepers or otherwise, as preferred.

The table 1 is provided with suitable slots or openings 9 and 10, Figs. 3 and 4, into which the respective arms 7 and 8 of the yoke enter, as shown in Figs. 22 to The arms 7 adapted to grasp the knuckle of the hinge 12, Fig. 19, and to which hinges are supplied by hinge-feed mechanism, to'be hereinafter more fully described. These spring-fingers 11 are provided with a side wall a, Fig. 18, that serves as a stop for the hinges, as will be hereinafter more fully explained. Each of these side walls a is secured to one of the springfingers 11 by means, for example, of a screw y, so that it becomes in effect a part of the hinge-fingers, and the inner faces of the arms 7 and 8 are slightly cut away to accommodate the walls a and thus permit the hinge-fingers to move downward in respect to the upper ends of the arms, as will be hereinafter more fully set forth.

Referring to Fig. 18, the central portion of the top of each of the arms 7 and 8 is cut away, so as to form a cavity 13.

As shown in Fig. 17, the hinge-fingers are formed by bifurcating or otherwise adapting a strip of spring metal 14, which is mounted in the cavity 13 by means of a fixed pin mpene= trating an oblong slot in its lower end, and this strip of spring metal is held normally up to place by means of a spiral spring 15, one end of which is secured to it and the other end of which is provided with a ring or nut and meshes with the threads of an adjusting-screw 16. By this arrangement the spring-fingers, together with their side walls a, are cushioned and may yield slightly when the spring 15 is overcomeor extended, the oblong slot and pin permitting of such motion. Moreover, the hinge-fingers may be adjusted laterally by turning the adjusting-screw 16, whereby the upper end of the spring 15, traveling in its threads, changes the inclination of the spring, and consequently the position of the hingefingers, by turning the strip ofmetal 14 in relation to its supportingpin.

For the sake of a further description it may be stated that hinges are supplied to the spring-fingers 11 of the arms 7 and 8 when the yoke or anvil 5 is in its lowest position, as shown in Figs. 1, 2, 10, and 21.

The rotation of the cam 6, Fig. 28, causes arms 7 and 8.

the yoke to ascend and carry the hinges upward into substantially the plane of the table, Fig. 22, whereupon the respective parts of a lid are fed through the intervention of sideslide lid-feed mechanism, to be hereinafter described, along the table and between the open leaves of the hinge. The continued ro tation of the cam 6 then lifts the yoke still farther, with the result that the top portions or faces 17, Fig. 17, of the arms 7 and 8 engage the lower leaves of the hinges, and thus push their barbs or projections 18 into the respectiveparts of the lid, as will be more fully understood by reference to Fig. 23, it being understood that during this operation the spring 15 yields and stretches somewhat, and thus allows the fingers 11 to be depressed beneath the planeof the tops or faces 17 of the While the barbs or projections 18 are being driven home in the respective parts of the lid, the latter are held against upward displacement by means of dogs 19, Figs. 3 and 4, that are pivoted so as to normally overlie the lids for the purpose mentioned and so as to be susceptible of turning in the direction indicated by the arrow, Fig. 4, when the lids are thrown out of the machine in a manner and by means to be hereinafter referred to. As shown in the drawings, Fig. 3, these dogs 19 are pivoted to the inner end i walls 20 of the hoppers or chambers that hold supplies of the respective parts of lids. The subsequent movement of rotation of the cam 6, Fig. 28, sustains the yoke 5 in elevated position long enough to permit the upper barbs or projections 21 of the hinge to be driven home, Fig. 24, by means of a hammer to be hereinafter described, whereupon the yoke again descends, thus drawing the hinge-fingers 11 clear of the knuckle of the hinge, and subsequently the yoke-like anvil is caused to again describe the movements and effect the results above set forth.

The hammer 22 is afforded a range of reciprocating motion in a vertical direction, is guided between the inner walls 20, and when free is drawn to its highest position by springs 23, which of course could be readilyreplaced by weights or other suitable means. This hammer is provided with two working faces disposed in alignment with the arms 7 and 8 of the yoke 5.

24 is a hammer-lever fulcrumed-as at 25, for eXampleto the Walls 20 and connected at its free end with an operating-cord 20. The intermediate portion of this hammer-lever 24 is connected with the hammer 22 by means of a pivotal link 27, and the outer end of this lever 24 is provided with a weight 28, or spring, which tends to depress the hammer-lever and also the hammer through the intervention of the link 27. The cord 26 is led over suitable guide-pulleys and connected with the trip-cam 29,Fig. 30, which is operated by the rotation of the cam 30,carricd by the shaft 4 in such manner that it (the tripcam 29) is drawn gradually upward, whereby IIO the hammer-lever 24 and link 27 are also drawn up through the intervention of the cord 26, thus permitting the hammer 22 to rise under the influence of its springs 23. The subsequent movement of rotation of the cam 30 effects the sudden release of the trip cam or finger 29, thus permitting the hammer 22 to descend suddenly under the influence of the weight 28, which of course overpowers the tension of springs 23 and in such manner that it strikes the upper barbs or projections 21 of the hinge and drives them home into the top of the respective portions of the lid.

The side-slide lid-feed is actuated by a cam 31, Figs. 26 and 27, secured to the main shaft 4, through the intervention of the cam-rod 32. This cam-rod 32 is afforded a range of reciprocation in a vertical direction and is guided at its upper end by means of a pin 33, depending from the table and working in an axial opening in the'rod' or other suitable means and at its lower end by means of a keeper 34, provided with a spring 35,tending to maintain the rod in elevated position. This rod is slotted for the accommodation of the shaft 4, and may be comprised of two parts fitted together telescopically and provided with an interposed spring 36, as shown in Fig. 26, whereby the lower part is permitted to move independently of the upper part when the spring 36 is overeome,the object of this construction being to provide an automatic adjustment for parts of lids differing slightly in width and to prevent breakage.

37 and 38, Figs. 2 and 3, are the side slides. These are made beveled, as shown, for purposes to be hereinafter described, and are afforded a range of travel in ways carried by the table 1, in order to feed the respective parts of the lid into the open leaves of the hinge, as has been above stated. As shown in said figures, the side slides 37 and 38 are provided with nuts 39, that engage adjustingscrews 40 and slide in grooves cut or otherwise formed in carriages 41 and 42, that slide in the ways 43 of the table.

44 are bell-crank levers fulcrumed to brackets depending from the table 1, Fig. 2, and having one of their respective ends in engagement with notches formed in the under side of the carriages 41 and 42, and having their other arms in engagement with notches formed at or near the top of the cam-rod 32. The rod 32 rises under the influence of its spring 35 and falls or is drawn down by reason of the motion of rotation of the cam 31. When the rod 32 is drawn down, it causes the side slides 37 and 38 to be drawn together, thus feeding thetwo parts of the lid between the open leaves of a hinge, in which position it remains, in order to hold the lids to place while the barbs of the hinge are being inserted therein by the operation of the hingecarrier anvil and hammer, as has been'already described. In this connection it may be said that should the parts of the lid be of undue Width then the spring 36 would yield, thus permitting the lower part of the rod 32 to move independently of the upper part, so that the cam 31 may accomplish its full throw without the possibility of breaking any of the parts. Moreover, the adjusting-screws 40 provide means for shifting the side slides 37 and 38, in respect to their carriages, in order to accommodate them to different-sized parts of lids. After the barbs or projections of the hinge have been driven home into the parts of the lid .the cam 31, by reason of its shape, permits the-rod 32 to rise under the influence of its spring 35 a shortdistance, whereby the side slides 37 and 38 are held a short distance clear of the lid and serve to guide the latter as it is delivered from the machine. The continued motion of rotation of the cam 31 permits the rod 32 to ascend under the influence of the force of the spring 35, thus returning the side slides to position for feeding the parts of another lid, which are delivered in front of them in a manner to be hereinafter described.

The throw-out mechanism, Figs. 1 and 4, comprises rollers 45 and 46, having their peripheries roughened or otherwise adapted to feed the lids out of the machine. These rollers are geared together-for example, by means of an endless band or sprocket-chain .47and are mounted in spring- depressed bearings 48 and 49, whereof the bearings 48 are carried by the walls 20 of the machine and whereof the bearings 49 are adapted to be raised and lowered, in a manner to be h'ereinafter described, in order to cause the rollers 46 to clear or to contact with the box-lid. Mo-

tion is imparted to the rollers 45 and 46 by means of an endless band or, preferably, a link belt 50, which, after passing over suitable guide-rollers, runs around a pulley 51, loose on the main shaft 4. Motion is imparted from the main shaft to the loose pulley 51 through the intervention of frictionfor example, by

means of a dished washer 52, Figs. 1 and 2,

fast on the shaft 4 and bearing on the sideof the pulley 51. The object of this construction is to permit the pulley 51 to remain at rest when the box-lid for any reason-for example, when 'the hammer is downmay not be thrown out of the machine by the rollers 45 and 46 and to permit the dished washer 52 to impart motion to the pulley 51 and rollers 45 and 46, as soon as the box-lid is released or otherwise enabled to escape from the machine.

There are in myimproved machine four mo tions that I shall arbitrarily designate, for purposes of description, secondary motions, because they may derive their movements from the primary motions above described. These secondary motions are the hinge-feed mechanism, the let-down motion for parts of lids, the alignment motion for parts of lids, and the rise-and-fall motion for the throw-out mechanism. Of these four motions, as illustrated in the drawings, the hinge-feed mechanism is operated through the intervention of IIO the hinge-carrier-anvil mechanism and the other three are operated by the hammer mechanism.

The object of the hinge-feed mechanism is to supply the fingers 11, Fig. 17, of each of the arms 7 and 8 with a hinge every time the yoke 5 drops. The hinges are arranged, for example, by the attendant in charge, in rows on the hinge-frames or supply-racks 53, Figs. 9 and 25, which are arranged on opposite ends of the machine and which are provided with grooves for the reception of the-knuckles of each row of hinges. Each hinge-frame or supply-rack 53 is fitted to slide endwise of the machine on guides, brackets, or keepers 54, secured immovably to the framework thereof, and is drawn in the direction indicated by the arrow in Fig. 9, either by means of a cord 56 and weight 55, as shown, or by other suitable means, as a spring, in order to permit it when released to bring the successive rows of hinges into line with the opening between the hingefingers 11.

The under side of each of the hinge-frames or supply-racks 53 is provided with a longitudinally-ranging groove 57, Fig. 12, having teeth, such as 57 and 58, disposed along its opposite edges. In the exemplification of my invention shown in the drawings these teeth are so arranged as that the teeth on one side are opposite the spaces on the other. The guides, brackets, or keepers 51 are longitudinally slotted for the reception of travelers or bolts 59, that are moved inwardfor example, as indicated by the arrow at the lefthand side of Fig. 10by means of weights or springs 60, as shown, and are provided at their respective ends with dogs 61, Figs. 9,10, and 11, that engage with the teeth, of which 57 and 58 are two, and thus effect the release and control the movements of the hinge frames or racks 53 and at their other extremities with catches 62, for purposes to be hereinafter described. 63 are pusher-rods, adapted to collide with the knuckles of the hinges and push them out of the grooves in the hinge-frame or supply-rack 53 and between the hinge-fingers 11. These pusherrods 63 are carried by pusher-blocks 64:, that slide longitudinally of the guides, brackets, or keepers 54, and are normally drawn inward by means of springs 65, or, if preferred, weights or other analogous means might be employed for this purpose. These pusherblocks are drawn in a reverse direction by means of cords 66.

From the foregoing description it is apparcut that the pusher-rod 63 tends to push a hinge out of the groove "in the part 53 and into engagement with the hinge-fingers 11 whenever the hinge-fingers are opposite the knuckle of the hingethat is to say, when the yoke or anvil 5 is in depressed position. As soon as one hinge has been pushed clear of the part 53, it collides with the plate or end too far-that is to say, so that when the yoke or hinge-carrier anvil 5 rises the outside end of the hinge is clear of the part 53 and the inside hinge in the part 53 bears upon the outside of the arms 7 and 8, and thus causes the pusher to remain at rest. After all the hinges comprising one row of hinges, located in one of the grooves of the part 53, have been pushed out successively by the pusher and received by the hinge-fingers and applied to lids the pusher-block is drawn back through the instrumentality of the cord 66 and through the intervention of mechanism to be presently described. When the pusherhlock-for example, the one shown in Fig. 11-is drawn back, it collides with the catch 62 and shifts it, together with the traveler or bolt 59 and dog 61, with the result that the dog 61 is drawn clear of the tooth 57 and into range of a tooth 58. (See Fig. 11.) At the same time the pusher 63 is drawn well out of the particular groove of the part 53, from which all the hinges have been last expelled. Whenthe pusher-block 64 is released, it is driven inwardthat is, toward the right in Fig. 10, for example-by its spring 65 or any equivalent of a spring, with the following results: During the first portion of its travel it is followed by the catch 62, thus permitting the traveler or bolt 59 and dog 61 to move under the influence of its actuating spring or weight into position for engaging the next tooth 57, whereby the part 53 is permitted to advance until the next one of its notches (containing a supply of hinges) is brought into line with the pusher 63 and is then held in such position. After this notch, containing hinges, has been brought into alignment with the pusher-rod 63 the latter continues to advance until it collides with said fresh supply of hinges.

A description will now be given of mechanism for drawing the pusher-blocks 64: outward in order to permit the parts 53 to change their position in order to bring a fresh supply of hinges into range of the pushers 63. Referring to Figs. 10 and 13 to 16, 67 is a shaft held against rotation, for example, by means of brackets 68, carried by the main frame of the machine, and provided-that is, the shaft-with a radially-projecting fixed pin 69. 70 and 71 are drums mounted so as to revolve freely on the shaft 67, and whereof the drum 70 is shown as of smaller diameter than the drum 71. The drum 70 is reciprocatedor rotated first in one direction and then in the other by means of a cord or chain 72, attached to the corresponding arm of the yoke or anvil 5, and by a spring 76, attached at one end to the drum and at the other end to the fixed shaft 67, for example, through the intervention of a pin 67. The drum 71 is connected at its periphery with a cord, chain, or similar device 66, which passes over a guide-pulley 75 and is attached to the pusher-block 64.

73 is a spring having one of its ends attached to the fixed shaft 67, for example,

IIO

through the intervention of the pin 69, and the other of its ends attached to the drum 71 and tending to rotate the drum 71 in a direction opposed to that which is given it by-the cord and in which the cord 66 passes around it. by the spring or weight that solicits the pusherblock inward.

From the foregoing description it will be understood that the drum 70 is constantly rotated first in one direction and then in the other, and that as the pusher-block 64 advances toward the right in Fig.10 and pushes out hinges the drum 71 is rotated thereby in a clockwise direction and is not connected with or influenced by the constantly-moving drum 70.

The drum 71 is provided with a spring-catch 77, normally contained within its Walls, but adapted to be pushed through a suitable opening therein into engagement with a tooth or projection 78, carried by or formed on the drum 70. As shown in the drawings, this spring-catch 77 comprises a pin mounted in bearings in the side of the drum 71, so as to be free to slide endwise, and a spring having one of its ends applied to the inner face of the drum and its other end fitted to a transverse opening in the pin, and said spring tending to push the pin out of range of the projection 78. In all positions of the pusher-block 64 during its inwardthat is, right-handed, in Fig. 10stroke, except its extreme inward position, the spring-catch 77 is contained within the drum 71 and is clear of the projection 78, Fig. 14, so that the drum 70 rotates first in one direction and then in the other, under the influence of the reciprocations of the yoke or anvil 5, while the drum 71 is turned toward the left under the influence of the pusherblock 64, which travels in a similar direction. However, when the pusher-block 64 has reached the extreme limit of its inward travel it has fed all the hinges out of the grooves 53 and has turned the drum 71 against the influence of its spring 73 until the spring of the catch 77 has collided with the fixed pin 69 (see Figs. 15 and 16) and pushed its free end outward into engagement with the projection 78 on the drum 70. Under these circumstances the next rise of the yoke rotates the drum 70 in a counter clockwise direction, and this rotation of the drum 70 is imparted through the intervention of the projection 78 and catch 77 to the drum 71, so that both drums are turned in a counter-clockwise direction, Figs. 15 and 16, and thus pull the pusher-block outward. As the pusher-block reaches its extreme outward position, the drum 70 commences to turn in a reverse direction under the influence of its spring 76, releasing the spring of the catch 77 and permitting it to free the latter from the projection 78. The drums are disconnected, the pusher-block 64 moves inward, and the drum 71 is turned under the influence of the motion of the pusher-block until the time has arrived for a However, this spring 73 is overpowered repetition of the above-described operation, whereby the drums are again locked together and the pusher-block again drawn outward for the purpose of feeding a fresh supply or row of hinges contained in the part 53. In this connection it may be remarked that, as shown in the drawings, the cord 72 is attached to the hinge-carrier anvil through the intervention of a spring 79, which by yielding is adapted to prevent accidental breakage and to take up or compensate for surplus motion.

For the sake of a further description I will here state that, as shown in the drawings, there are two compartments 80 and 81, Figs. 3 and 21 to 25, which have as their bottom the top of the table, and have inner vertical walls 20, end walls 83 and 84, and side walls 85, which ('i.e., the side walls) may be broken away at their intermediate portions. These compartments 80 and 81 constitute, as it were, hoppers for containing piles of the respective parts of the lids, it being understood that the inner walls 20 donot extend all the way down to the table, so that openings 82 are formed, through which the respective parts of the lid are fed by means of the side slides 37 and 38, as has been already described, into position for receiving the hinges.

To enable the part of the lid at the bottom of each or one pile of parts to be readily fed forward by the side slides 37 and 38, it is desirable to support the remaining parts of lids above and out of contact with it, more especially in cases where the parts of the lid are comparatively large-for example, like the parts contained in the hopper 80. Iwillnow, with reference more especially to Fig. 6, proceed' to describe mechanism for letting down parts of lids one at a time and at the bottom of a pile. 87 is a spring-hook carried by the inner wall 20 and tending normally to underlie the bottom one of the pile 86 of parts of lids and to hold the same above the part which is supported by the table and is clear of the pile. The section of lid that is held up by the spring-hook 87 is supported at its outside end by the thickest portion of the side slide 37, which is beveled for this purpose at its top, as has been already described, and the thinnest portion of the side slide 37 pushes the section of lid that lies upon the table inward into position in range of the hinge. From the foregoing it will be understood that economy of power in operating the side slide is effected because the section of lid which is being fed slides freely on the table, and because the friction of the thickest portion of the side slide as it travels under the pile of sections of lids is not sufficientto be of practical importance. After the hammer 22 has driven the top of the barbs of the hinge home into the respective parts of the lid it commencesv to rise, with the result that the completed hinged lid is released and thrown out of the machine, as will be hereinafter more fully described. As the hammer 22 continues to rise, the side slide 37 moves outward, as has IIO hammer.

been described, and the cord 90, connected with the hammer, gradually pulls the springhook 87 into the position shown in Fig. 6 clear of the part of lid 88, so that the latter falls upon the table into position for being fed forward by the side slide.

91 is a dog normally solicited by springs 92 into engagement with the inner edge of the section of lid 93. However, the hammer is provided with a stud 94, adapted to collide with one arm of a bell-crank 95, pivoted to the wall 20 and having its other arm extended into a slot in the dog 91, so that when the hammer is down the stud 94, acting through the intervention of the bell-crank 95, draws the dog 91 against the force of its springs 92 clear of the edge of all the sections of lids, so that the inner edges of the latter are supported only by the hook 87, as has been explained. However, as the hammer rises the dog 91 is released by the ascent of the stud 94 and is thereupon moved outward by its springs 92 into position for engaging the edge of the succeeding sections of lids and causing each of them to be held, as shown, and to sustain the sections of lids above during the time that the hook 87 is drawn back clear of the sections of lids in order to permit the bottom one to fall onto the table, as has been already described. In the drawings I have illustrated thelet-down motionin application to only the larger parts of the lids-21 e., to only one side of the machine.

It is of course important that the sections or parts of lids which are fed from the hoppers 80 and 81 should be in alignment, and to insure this resultI have provided an alignment motion, which I will now proceed to describe with reference more particularly to Figs. 3, 5, 7, and 8, and which is operated by means of the 0011126 that appertains to the The wall Si is slotted in each of the compartments 80 and 81 and preferably near the table.

96 is a .cam-block pivoted within said slot and adapted to push inward against the edges of the respective sections of lids, so as to press their opposite edges against the wall 83, and thus insure their alignment. In the exemplification of my invention (illustrated in the accompanying drawings) this cam-block is provided with a spring-toe 97, one end of which is secured to the cam-block 96for example, near its fulcrum-and the other end of which is free and operates upon the parts of lids. However, the free end of this camblock and also its spring-toe 97 must be drawn into its slot, Fig. 7, when the parts of lids are being movedz'. a, let down, as has been described hereinabove.

98 is a reciprocating bar afforded a range of endwise movement in suitable stirrups which are provided on the exterior of the wall 84:.

99 is a rock-shaft pivotally supported by the outside wall and by a suitable support, as b. One arm 99 is fast on said rock-shaft and has its end attached to the cord 26, Fig.

the wedge-like faces of the cam-blocks 96, and

which are fitted to move in inclined grooves 101, Figs. 7 and 8, cut or otherwise formed in the reciprocating bar 98. However, these studs 100 are attached to springs 102, which tend to draw them into the position shown in Fig. 8. Referring to Fig. 8, when the reciprocating bar 98 is moving in the direction indicated by the arrow the stud 100 collides with the wedgelike face of the cam-block 96, and thus turns it toward the left in said figure, with the result that the spring 97 collides with a section of lid and pushes it over against the wall 83, as has been already referred to. As the reciprocating bar 98 continues to move, the stud 100 slides off the wedge-like face of the cam-block 96, as shown in Fig. 7, with the result that the cam-block is turned under the influence of the spring B into the position shown in said figure. lVhile the reciprocating bar 98 is completing its return stroke, or, in other words, traveling in the direction indicated by the arrowin Fig. 7, the stud 100 bears upon the free end of the cam-block 96, and consequently is prevented from traveling with the reciprocating bar 98, it being understood that the spring 102 yields during this time. Under these circumstances the stud 100 is gradually shifted by reason of the inclination of the slot 101 and by reason of the return movement of the reciprocating bar 98 toward the right until it clears the free end of the cam-block 96, at which time it is of course at the lower end of the slot 101, Fig. 8. As soon as the stud 100 has cleared the free end of the cam-block in the manner above described, its spring 102 returns it to the upper end of the slot 101 into position for again actuating the cam-block 96 in the manner shown in Fig. 8.

I will now proceed to describe the rise-andfall motion for the throw-out mechanism, whereby the constantly-rotated rolls 46, Fig. 4, are lifted up and depressed so as to collide with the lids after thehinges have been applied thereto and .in order todeliver them from the machine, and for this purpose I shall refer to the drawings.

103 is a lever fulcrumed or pivotally attached at one end to the inner walls 20 and connected with the hammer-lever 24--for example, by passing its free end through a slot 104: in the link 27, so that the free end of the lever 103 rises and fallsas the hammer rises and falls. As shown in the drawings, the free end of this lever 103 carries a yoke 106, secured to the boxes of the bearings 49 of the rollers 46. 105 is a set-screw that may be interposed between the parts 103 and 106 in order, to facilitate adjustment. When the hammer 22 descends and strikes the hinges, the rollers 46 are permitted to bear under the influence upon the respective parts of the lid through the operation of the lever 103 and yoke 106, and since the rollers 46 tend to revolve, as has been described, they tend to feed the lid to the revolving rollers 45, and the operation of the rollers 45 and 46 results in the ejection of the lid as soon as the latter is released by the side slides, anvil, and hammer. However, during the first part of the rising motion of the hammer the lever 103 and roller 46 are not lifted,because the slot 104 is long enough to prevent the accomplishment of this result, and during this interval the lids are ejected from the machine. V ever, as the hammer continues to rise the bottom of the slot 104 collides with the lever 103 and lifts it, together with the rollers 46, so that the latter are lifted up after the finished lid has been ejected, and in order to permit the parts of the next lid to be fed under them by the operation of the side slides 37 and 38, which has been already described. In this connection it may be remarked that the table may be grooved, as shown at C, for the accommodation of the knuckles of the hinges as the lids are ejected.

The machine is adapted to accommodate parts of lids of considerably different dimensions, and the manner in which I attain this result will be now explained with reference more particularly to Fig. 3.

To accommodate the hoppers 80 and 81 for the reception of longer parts of lids, I have provided screws 107, having at their ends, respectively, right and left hand threads meshing with suitable nuts carried by the end walls 83 and 84, which are free to move transversely of the table 1. These screws 107 are connected together by an endless belt or chain 108 and its complemental pulley 109, so that when one of the screws 107 is rotated by means of a wrench, key, or crank the other one of these screws is similarly rotated, so that the end walls 83 and 84 are shifted in the required direction and are maintained parallel in respect to each other. The side walls 85 are fitted to slide lengthwise of the end walls 83 and 84, which are provided with racks 110.

111 are revoluble shafts journaled to the walls 85 and afforded a range of motion in respect to the walls 83 and 84, for example, by providing the latter with oblong slots.

112 are pinions splined or otherwise mounted so as to slide on the shafts 111 and meshing with the racks 110, so that when these shafts 111 are rotatedfor example, by means of a key or wrench-the pinions and racks operate to shift the side walls 85 inthe required direction and to the required extent for the reception of the particular size of parts of lids. Moreover, since the pinions 112 are splined to or otherwise mounted so as to slide on the shafts 111, they are free to move with the walls 83 and 84 when the latterare adjusted, and in fact are constrained so to do by lips 113, disposed in range of the sides of the pinions and projecting from the racks 110, which are carried by the end walls. Suitable clamps may be provided for locking the movable walls 83, S4, and 85 to place after their adjustment.

The part herein designated an anvil serves to drive projectionsinto the under faces of the lids. During this operation the lids are held down by devices for holding them, which in the present instance, comprise the dogs 19 and the hammer.

Having thus described the various motions, which have been herein arbitrarily designated primary and secondary motions, and adju'stments and referred to the work to be accomplished by each, I will here state that said motions are of course timed. in respect to each other with a view to the mode of operation of the machine, which latter may be described as follows:

The hoppers or chutes and 81 are adjusted in the manner above described, so as to accommodate parts or sections of lids of any particular size to which it is desired to apply hinges, and are thereupon filled and kept supplied with such parts or sections, and it may be remarked that as described the parts are placed rough-side up, and that the lids are upside-down when they leave the machine. By reason of the timing-of the various movementsof the machine the hammer 22 and rolls 46 are lifted, the hinge-carrier anvil is depressed, hinges are supplied to the hinge-fingers 11 by'the hinge-feed mechanism, and in the manner above set forth, the spring-hook 87 and dog 91 operating in the manner described, let down the respective sections of a lid onto the table, and the side slides 37 and 38 push the same inward between the. leaves of the hinges which have been brought into position for permitting of the accomplishment of this result by the rise of the hinge-carrier anvil. The continued rise of the hinge-carrier anvil 5 and the descent of the hammer cause the barbs or projections of the hinges to be driven home into the respective parts of the lid, as shown in Fig. 25, and as the hammer commences to rise and'the hingecarrier anvil commences to fall and after the slides have moved backward sufficiently to free themselves from contact with the lid the rollers 45 and 46 throw out the completed must supply the parts 53 with hinges, and

IIO

these hinges are automatically fed from the parts 53 to the hinge-fingers 11 in the manner and by the means hereinabove stated.

Clearly the hereinabove described machine is applicable for use in applying hinges which are modifications of those shown in the drawings and which are provided with barbs or projections either at the top or bottom or in an intermediate position, and which are so constructed as to be susceptible of being retained against accidental dislodgment due to the motions of the machine.

It will be obvious to those skilled in the art to which my invention relates that modifications may be made in details without departing from the spirit thereof. Hence I do not limit myself to the precise construction and arrangement of parts hereinabove set forth and illustrated in the accompanying drawings; but,
