SPECIFICATION forming part of Letters Patent No. 558,013, dated April 7, 1896.

Application filed July 23, 1888. Serial No. 280,755. (No model.)

To all whom it mag concern.- my special intention to provide a machine Be it known that I, GEORGE WV. DAY, of containing not only mechanism adapted to 1 Ilaverhill, in they county of Essex, and in the best drive the staples or double-pointed tacks State of Massachusetts, have invented certain delivered to the hammer or driving device,

Pivoted in the lower partly in elevation, showing the lower porportion of the frame or standard is the treadle tion of the staple receiving and holding plate 0, pivotally connected at its inner end to the and the inclined staple-engaging face beside lower end of rod B and on its outer end prothe hammer-bar way. vided with a suitable foot-piece of the usual 40 Letters of like name and kind refer to like form and construction. The upper end of the parts in each of the figures. treadle-connecting rod B passes up through The object of my invention is to provide an opening in the top of the main upright certain improvements in machines for drivportion of the frame. Passing through and ing staples applicable to the fastening of the guided in another opening in the frame in 45 soles of boots and shoes and for other purfront of the rod B is the stem or shank D of 5 poses; and to this end my invention consists the horn E for supporting the boot or shoe in the machine and in the construction, arsole while the staples are being driven into rangement, and combination of the parts it. This horn is of the usual and well-known thereof, as hereinafter specified. construction of such device in use in boot 7 50 In carrying out my invention it has been and shoe machines, except that it is provided zoo with a die or anvil of a peculiar form and construction adapted to clench the staples in a manner to be described hereinafter.

The upper portion of the horn-shank D is guided, as described, in a suitable opening in the frame-standard, while its lower end projects down through and is guided in an opening in the bracket or fixed arm A within said standard. On this shankis a collar D, preferably, as shown, fixed in place by means of a set-screw d. Surrounding the horn-shank is the spiral spring D engaging with its upper end the fixed collar D and with its lower end the sliding collar D made movable on said shank. A fork B, attached to and carried by the treadle-rod B, engages the under side of this sliding collar with its fork-arms, which project forward between the collar and the horn-shank-guidingbracket or arm A 011 the frame-standard. Besides engaging the collar D so as to raise it when the treadlerod B is raised, this fork also serves as a stop to limit the downward movement of the rod by coming in contact with the upper side of said frame arm or bracket A.

The fixed collar D is so situated on the horn-shank D as to be, when the horn is down, some distance below the point where the shank passes through the top of the frame-standard. This construction and arrangement is to allow the horn-shank and horn to rise a certain distance, for a purpose to be described hereinafter. If desired, an elastic or semielastic washer d can be placed between the shoulder at the lower end of the horn E and the top of the frame-standard to take up any shock and prevent noise when the horn descends after being raised.

With the construction set forth when the treadle is operated to raise rod B the horn E will, through the fork B, collar D spring D fixed collar D, and shank D, be raised, and as long as the rod B remains elevated the horn will be held in its raised position by the stress of the spring D compressed between the sliding collar D and the fixed collar D, by the action of the fork B on rod B, engaging the sliding collar. WVith the treadle-rod raised, the horn will then be capable of a certain amount of yielding to a downward blow or pressure on the top of the horn. This yielding, which is provided for by the spring D is for a purpose that will be explained hereinafter. lVhen the treadle is released, the spring will, through the sliding collar and the rod-fork engaged thereby, tend to return the treadle-rod and treadle to their first positions again, and the horn will drop until the shoulder at its lower end rests again upon the top of the frame-standard or the cushionwasher thereon.

The top of the horn E can be of any de sired shape or be provided with any desired form of anvil; but I prefer to provide it with the anvil E, (illustrated best in Figs. 11 and 12,) having its upper face formed with an annular concavity or groove. As seen in crosssection, this groove has its sides beveled or made inclined, the bevel or incline being preferably a concave one. The annular groove is of such diameter that the lower ends of the two legs of a staple to be used can be in contact at the same time with inward and downward inclines at opposite outer sides of the groove. This arrangement is to secure a simultaneous inturning and clenching of the staple ends when the staple is driven down against the anvil.

Projecting up from the frame-standard A is the upright A which can be cast in one piece with said standard or made separate and bolted or otherwise fastened thereto. Sliding vertically at one side of this upright A is the bar G, guided in its reciprocations by means of the guide-blocks G G engaging slots g g in the bar. Screws G2 G passing through the guide-blocks and tapped into the upright, hold the blocks in place and, by means of their heads overlapping the sides of the respective slots, serve to keep the bar securely in place, while leaving it free to slide. At or near its lower end the bar G is provided with a forwardly-projecting lug or arm G to which is screwed or otherwise fastened the upper end of the treadle-rod D.

I do notlimit myself to the particular means shown and described for holding and guiding the bar Gin its movements. Any other of .the well-known forms and constructions of guiding devices for reciprocating bars or pieces can be used without departing at all from the spirit of my invention.

In a portion of bar G, at the rear side thereof, is a vertical slot g for receiving the adjustable pins g 9 Each of these pins has a head projecting out beyond the side of the bar and overlapping the front and rear edges of the slot g. The-other end of each pin is threaded and screwed into a plate or nut g overlapping the sides of the slot onthe inner side of the bar. With this construction, when the pins have been adjusted, as desired, along the slot 9, they can be fixed as adjusted by screwing them in so as to clamp portions of the bar firmly between the pinheads and the respective nuts. Projecting between these pins is an arm of the lever H pivoted to the upright A at h. The pins form adjustable abutments or blocks adapted to strike the lever-arm and move the lever, as the bar G nears the limits of its movement in opposite directions, and to leave the lever without movement while the bar is moving over the middle portion of its travel. A pin G fixed to the bar G, projects therefrom through a slot in the upright A to a point beyond the other side of the latter.

Upon an arm A extending upwardly and forwardly from the upright A is the guide for the hammer or driving-plunger situated verticallyover the upper anvil-bearing end of the horn E.

The hammer or plunger head I consists of a bar of steel, permanentlymagnetized, which ends.

558,013 r p a is guided and slides in a groove is in a vertical plate or block K, of brass or other nonmagnetic material. A plate K, also of nonmagnetic metal or material, preferably brass, engaging the bar I on the side not in contact with plate K, serves to keep the bar in place in the groove It. The brass plate K, which thus completes the inclosure of the vertical way for the reciprocating magnet-bar I, is shown as fastened in a groove or rabbet in the front vertical face of the arm A of the upright A by means of screws. I do not, however, limit myself to such an arrangement or such means of fixing the plate K in place. All that is necessary is that the magnet-bar I, forming the hammer-head, shall be guided vertically and that its guideway shall be inclosed by or made of non-magnetic metal or material. The magnet-bar I is at its upper end clamped and held in a slot 1" in the end of the plunger I by means of screws i F. The extreme lower end or head of this plunger is enlarged, as shown, and is provided with a rearwardly-extendin g guide-arm I engaging a vertical guide-slot L in the up right guide-bar L, fastened at its lower end to the arm A of the frame-upright A A second guide-bar L parallel with and in front of bar L, is also supported at its lower end from arm A Any desired means or method of supporting and holding these guide-bars in place can be used.

As shown, the lower ends of the rear and front bars are respectively clamped against a vertical piece on arm A and the front side of plate K by means of two bolts L L passing through the guide-bar ends, the plate K, and the piece on arm A WVith this construction these bolts serve the double purpose of fastening the lower ends of the guidebars and holding the brass plate K in place to properly guide the magnet-bar I in its way.

Between the upper ends of guide-bars L L the block L is clamped by means of the two bolts passing through the block and bar Tapped down through a hole in block L is the hollow externally-threaded screw L through which passes the upper end of the stem or shank of the magnet-bar carrying plunger I. A lock-nut L is provided on this screw above the block L to lock the screw from turning when it has been adjusted up or down to raise or lower its lower end. Surrounding the stem or shank between the end of screw L and the enlargement or head at the lower end of the plunger-shank is a spiral spring I. The stress of this spring in its downward pressure on said enlargement or head, and so the force with which it will drive the plunger and magnet-bar downward when they havebeen elevated, can be adjusted at will by loosening the locking-nut L and turning the screw up or down. The

guide-arm I on the plunger engaging the slot L in the rear guide-bar L serves to prevent any twisting or rotation of the plunger to cause binding of the magnet-bar I in its guideway. i

To take up shock and deaden any noise caused by the descent of the plunger I contemplate placing at L one or more cushions of rubber resting on the top of the guidehead through which the magnet-bar passes in position to receive the lower end or face of the enlargement on the plunger.

To raise the plunger and magnet-bar of the hammer against the stress of the spring I and then release them, so that they will be driven down again by the spring to deliver a blow to drive a staple, I prefer the means and mechanism shown best in Figs. 1 and 3.

Pivoted to the upper end of the sliding bar G, which is connected with the treadle-rod D,as hereinbefore described, is the pawl-lever M, provided with the shoulder m to engage the under side of the arm I on the plunger. This shoulder is so situated that when the sliding bar G and the pawl-lever are down in their lowest positions it is free to be moved in under the end of arm I by a forward swingin g of the pawl-lever M upon its pivotal connection with sliding bar G.

The upper end of the pawl-lever projects I up between guide-lugs M M on the rear guidebar L. A spring M engaging the rear side of the upper end of the pawl-lever tends to force the same forward. On the forward side of the pawl-lever, above the shoulder or lug m, is an incline an, adapted, as the pawl-lever is raised, to come in contact with the tripping pin or bolt M so as to cause a rearward swing of the pawl-lever sufficient to disengage the shoulder m from the arm I as the sliding bar G and the pawl-lever reach the limit of their upward movement. On the pawl-lever below the ing or shoulder m is an upward and forward incline, adapted to engage the end of arm I when the plunger is down and the pawllever is being lowered. This incline or cam will cause the pawl-lever to swing rearward until the shoulder 0% passes below the arm 1 when the spring M will swing the pawl-lever quickly forward to bring said shoulder under and in engagement with the plunger-arm.

In order to insure a full upward movement of the sliding bar G, the pawl-lever, and the plunger before such parts can descend again and to hold them from descent, as desired, when only partially raised by movement of the treadle and treadle-rod, I provide the rear side of the sliding bar G with a series of ratchet-reeth O O to be engaged by the nose of pawl O, pivoted at O to the frame-upright A A spring 0 presses up against the lower end of this pawl, which is so shaped that the pressure of the spring will tend to hold the pawl as swung'into position to engage the teeth 0 or to stand clear of them. This object I attain by providing the lower end of the pawl with a projection or edge so situated that when the pawl is swung forward to engage the ratchet-teeth the line of upward pressure of the spring will be to the rear of the pawl-pivot. When the pawl is swung back away from the teeth 0, the forward movement of its lower end brings the line of pressure of the spring in line with or slightly to the front of the pivotal point of the pawl. The one spring then serves to hold the pawl yieldingly in position to properly engage the ratchet-teeth and to retain it away from the teeth when it has been swung out of engaging position. A cam-lug O on the sliding bar G below the ratchet-teeth serves to engage the upper end of the pawl and carry it rearward as the bar reaches the limit of its upward movement. The lower side of the lug O is made abrupt and is in position to engage a stop-screw O on the short arm 0 on the pawl as the bar G reaches the lower limit of its motion, so as to swing the pawl forward again into position to engage the ratchetteeth 0 O.

The way in which the magnet-bar I formin g the hammerhead fits and slides is of such size and shape as just to allow the free passage up and down within itof one of the staples to be used-that is, the way is of a width equal to or slightly greater than the width of one of the staples between the outer sides of its opposite legs and is of a depth equal to or slightly greater than the thickness of the staple. With this construction a staple clinging by its top to the lower end of the magnetbar can rise and fall in the way as the magnet-bar is raised and lowered, and will, by the walls of the way, be held and guided in a vertical position with the points of its legs downward in line with the said hammer-bar. If then an iron or steel staple be fed to the magnet-bar in such position that its top or head shall be attracted and held to the lower end of the bar by the action of the magnetism in the latter, the staple will be drawn up within the magnet-bar way as the bar rises and will be retained in position on the bar end to be driven by the descent of the bar straight into a shoe-sole or other object held below the lower end of the barway.

In order to automatically feed the staples in proper position to the magnet-bar, so that each time the bar rises it will take a staple with it ready to be driven by the fall of the bar, I have provided the following feed mechanism: Attached to and carried by a slide P, having a slot P, engaging a guide-block P fastened to the side of upright A is the hopper R for receiving and containing a supply of staples. The screws p p, which fasten the guide-block in position, also serve, by means of their heads overlapping the sides of slot P, to retain the slide on the block.

As indicated hereinbefore, the staples to be used should be made of metal adapted to be attracted by the magnet-bar as the ordinary iron or steel staples or double-pointed tacks now in the market. The hopper R is,

as shown, divided within into chambers by a transverse upwardly-extending partition R.

In this partition, which is preferably curved or inclined toward the forward side of the hopper, is a slot R whose lower portion is of a width about equal to the width of the space between the legs of one of the staples, but

not as great as the extreme width of the tack. The upper portion of the slot is enlarged, so as to have a width equal to or a trifle greater than the extreme width of a staple between the outer sides of its legs. The forward side or end of the hopper is likewise provided with a similarly formed and shaped slot in line with that in partition R. Fora reason which will appear hereinafter the narrow portion of the slot in the hopper end is not as long and does not extend up as high as the corresponding portion of the slot in partition R.

The supply of staples or double-pointed tacks is placed directly in the rear chamber or compartment of the hopper, as indicated best in Figs. 6 and 10. The lever 11, intermittingly actuated, as hereinbefore described, by the movements of bar G, is connected with the hopper-carrying slidep by means of a pin 19 on the slide engaging a fork on an arm of the lever. Extending forwardly and downwardly within or along the arm A on upright A and at its forward end opening into the magnet bar guideway near the lower end thereof, is the way or passage down which the staples are fed to the bar. Within this feedwayis the forwardly and downwardly inclined plate S, turned up 011 edge, so as to receive the staples astride of its upper edge and of such thickness as to hold the staples steady while leaving them free to slide down of their own gravity toward the lower end of the plate. This end of the staple-receiving plate is, as shown, flush with the inner or rear side of the magnet-bar guideway, so that with the staples left free to slide down the plate the lowest or end staple will, when the magnet-bar is down, rest directly against the rear side of the bar. The plate is to be made of brass or other non magnetic metal or material, in order that no magnetism of it may interfere with the down.- ward sliding of the staples. Situated above plate S is a bar or plate S, also of brass or non-magnetic material, having its lower side parallel with the upper edge of the plate S and at such distance therefrom as to just leave space for the travel of the tops of the staples down along the plate-top. This bar will then, while not interfering with the sliding of the staples downward and forward toward the hammer-magnet, serve as a guide to keep the staples down in proper position astride of the plate edge. Pivoted to ears 8 s on the upper end of plate S is the swinging plate S whose upper edge, when the plate is swung up, comes into line with and forms a continuation of the upper edge of plate S, as indicated in Fig. 10. \Vith the pivotal point of the swinging plate below its upper edge, the ends of the two plates at their upper edges can be employed as stops to limit the upward swing of plate S when the edge of such plate has been ICO brought into line with the top of the fixedplate. The rear or outer end of plate S ,which is of the same thickness as plate S, so as to readily receive staples astride of it and allow them to slide freely along it when the plate is tipped up, is in position to project into the hopper B, through the vertical slots in the hopper end and partition R. Toward its outer end the plate is cut away underneath, so as to provide a point at the extreme plate end adapted, if the plate be thrust into a mass of staples, to most readily pass between the legs of one or more of the staples.

Attached to the plate S is a lug 8, supporting the bar S above and parallel with the upper plate edge. Such bar, like bar S above plate S, serves to keep any staples astride of the upper edge of plate S down in proper position while leaving them free to move or slide along the plate. At its forward end this bar S projects beyond the end of plate S so as to overlap the upper edge of the rear portion of plate S when the swinging plate S has been swung up. The lower side of the bar then is in line with the under side of guide-bar S and forms therewith a continuous guiding-surf ace to keep the staples down in place as they slide forward and downward toward the hammerbar. The rear end of the bar S which does not project back to the point of plate S is turned or inclined upward and rearward away from the top of the plate.

Pivoted to frame-upright A on the opposite side from bar G and lever H is the lever T, provided with a fork t on one arm engagin g the pin G on the bar G already described herein. Carried by the upwardly-extending arm of lever T is the rearwardly-extending curved bar T. The upper edge of this bar is, along its rear portion, curved substantially on the arc of a circle struck from the pivot of lever T as a center. From this portion concentric with the swing of the lever" the upper bar edge is formed on an eccentric downward and inward curve approaching nearer and nearer to the pivotal center of the lever T. This eccentrically-curved portion of the bar is provided with the series of teeth orinclinedfaced projections t t. On the side of swinging plate S in position to be engaged by the upper edge of bar T, is the pin or stud t having its under bar-engaging side preferably made wedge-shaped or with oppositely-inclined faces, as shown. The radius of the swing of the lever T and of the concentric portion of the upper curved edge of the bar T is of such length that when, by the movement of the lever, this concentric portion of the bar is brought under and into engagement with the stud or pin 29 the plate will be swung up into its uppermost position with its upper edge in line with the corresponding edge of plate S. As the lever is swung forward to bring the downwardly-curved portion of the bar edge under the pin or stud t the plate S will be allowed to swing down lower and lower. A rearward swing of the lever T to bring successively higher and higher portions of the eccentrically-curved part of the upper edge of the bar under the stud t will then cause an upward swing of the plate S until the concentric portion of the bar edge engages the stud. The teeth or projections on the upper edge of the bar will, as they ride under the stud 2?, give a series of jars or shocks to the plate as the latteris being swung upward towardits most elevated positionin which it is held without-movement by the con centrically-curved plain portion of the bar edge when such portion is brought under the stud.

To provide for adjustment of the bar T with reference to the arm of lever T carrying it, the forward end of the bar is fastened to the lever-arm by means of a screw i passing through a slot t in such arm and tapped into the bar. About midway of its length said bar is provided with a pin 15 which projects through a slot 15 in the lever-arm and engages the upper end of the plate 15 adjustably attached to the lever-arm by means of a screw i passing through a slot t in the plate into said arm. With the construction described the bar can be adjusted to regulate the height or angle of its upper edge with referenceto the lever-arm by loosening the screw t raising or lowering it in slot t and tightening it up again and by raising or lowering the adjustable plate 15 As already described hereinbefore, the pins or abutments g g on the sliding bar G for striking and actuating the arm of the hoppermoving lever H are so situated that the lever will only be moved as the bar nears the upper and lower limits of its motion. As the bar nears its lowest position the upper of the two pins g g? will strike the lever-arm, and, depressing it, will cause the lever to slide the hopper forward. Just as this forward movement of the hopper occurs the lever T has been moved by the described connections with the sliding bar G to bring the lowest part of bar T under the stud t on plate S and such plate has been allowed to swing down to bring .its nose or outer-pointed end into its lowest position. As the hopper is moved forward, the end of the plate S will then, riding over the bottoms of the slots R R in the hopper end and partition R, be thrust into the mass of staples in the rear chamber of the hopper. The hopper then remains in its forward position until the bar G is raised again and approaches the upper limit of its motion and the plate S through the action of the lever T and bar T, has been swung up into its elevated position with its upper edge in line with the top or upper edge of plate S. lPivoted in the bar S above the edge of the staple receiving and guiding plate S is the lever U, having its forward lower end in position to rest upon the top of the next to the lowest one of a series of staples astride of the plate. A spring u in a suitable recessin thebar S serves to press the end of the lever downward IIO into operative position. \Vith this construction and with the magnet-bar of the hammer down, the lowest or first of a series of staples on the plate will rest against the side of the bar and the neXt one will have its top engaged by the end of the lever U. When the lowest or first staple is taken by the magnet-bar, as hereinafter described, the rest of the staples will, by the action of the holder-lever, be prevented from sliding down toward the magnetbar way.

To cause the holder-lever to allow the staples to slide down to bring another one in con tact with the magnet-bar when the latter has descended again, I provide the trip-lever V, having its lower end projecting slightly into the magnet-bar way near the lower end thereof, so as to be struck by the bar and moved outward as the latter reaches or nears its lowest position. The other end of this triplever is connected by means of link V with the holder-lever U, so as to raise such lever from any staple 'on the plate S as the lower end of the trip-lever is engaged by the hammer magnet-bar.

To provide means for guiding a shoe-sole being stapled so that the staples will be driven in proper place, I employ a channelguide \V, having its end in line with the magnet-bar way. This guide is adapted to engage such a channel in the shoe-sole bottom as is usually made where the sole is to be stitched. As the sole is moved along to receive the successive staples it will then be guided so that such staples will be driven in proper line with reference to each other in the shoe-sole channel. The guide is preferably made adjustable, as shown so that it can be properly adjusted to the depth of the channel in the sole. For this purpose it is formed on the lower end of a plate fitting in a vertical groove or way u; in the plate containing the lower portion of the magnet-bar way. A screw in, engaging a slot 20 in the plate or piece carrying the guide, serves to retain it in its groove. The upper end of the piece is, as shown, beveled or made inclined to engage the inclined under side of the cam-slide WV, adapted to be moved horizontally as desired. The upper side of slide \V is horizontal and engages the horizontal upper side of the rabbet in which the slide is placed. A screw Q02, e11 gaging the slot 10 in the slide, serves to fasten the slide in place as adjusted. Vith this construction the channel-guide can be readily adjusted up or down and fixed as adjusted. \Vhere it is to be lowered to project farther below the lower end of the hammer-bar guideway, the cam-slide can be moved out, so as to cam the guide-carrying piece down, and then fastened by its screw 10*.

Icontemplate making the bar or plate K, in which the magnet-bar guideway is cut, in one piece from its top to its lower end; but in the drawings I have shown it, for convenience in assembling the parts,as made in two parts,the upper one held in place, as described hereinbefore, by bolts L L and the lower one fastened by screws. The bottom of the front compartment is made, as shown in Fig. 9, inclined to one side, so that any staples falling into such compartment will slide down and out of the spent 7" when the gate 0*, closing the latter, is opened.

The operation of my machine, as shown and described, is, briefly, as follows: \Vith magnet-bar of the hammer down and a number of staples on the inclined plate S, with the lowest or front staple against the magnet-bar I, and with a supply of staples in the hopper, the machine is ready to staple the sole of a shoe placed on the horn E. If now the treadle be pressed down to raise the treadle-rod, the horn will be raised with a yielding pressure to bring it up against the lower end of the magnet-bar-guiding head. The channelguide meanwhile takes into the channel in the shoe-sole, so as to determine the position of the latter properly. As the treadle-rod and the vertically-sliding bar G connected therewith rise, the pawl or pawl-lever M, pivoted to the bar, raises the hammer-plunger against the stress of spring I by the engagement of its shoulder m with the under side of the arm on the plunger. Meantime, while the magnet-bar-carryin g plunger is being raised to compress its spring the lever T, carrying bar T, is by its connection with bar G being swung rearward, causing the toothed portion of bar T to ride under the stud t on plate, so as to elevate the rear end of the plate. 'While the plate is being swung up it is given a series of sharp jars or shocks by the passage of the teeth on the bar edge, passing under the edge on the under side of stud 25 The purpose of this is to settle any staples between which the nose of the plate has passed on penetrating the contents of the hopper squarely astride of the upper edge of the plate. Anythat do not thus become properly seated on the plate will be jarred off as the upward swinging and jarring of the plate is continued. As already described hereinbefore, the nose of the plate, tapered down to a point, is caused to enter the mass of staples in the hopper while the plate is down by the forward motion of the hopper itself. cilitate the entrance of the plate-nose'between the legs of any of the staples coming in its way as it enters the hopper and to best secure the seating of such staples astride of the plate, it is not only cut away on an incline underneath, as described, but also preferably has its upper side or edge inclined or rounded a little upward and rearward above the line of the main part of the plate edge. The plate S is by the continued movement of the lever T and bar T swung up with a jarring motion until the plane concentric part of the upper edge of the bar T comes into engagement with stud 25 The plate is then tilted up at such an angle that the staples astride of its upper edge slide forward and downward onto the plate S, along which they slide down to To fa- IIO those already in place thereon. Any staples picked up by the nose of plate S in the hopper are kept from sliding down along the plate by the narrowness of the lower part of the slot R in the hopper-partition until the plate has been swung up to raise itabove the narrow and into the wide part of the slot. As the staples slide along down the plate any not seated squarely over the plate edge will be shaken or jarred off, so as to fall into the front compartment of the hopper, from which they can be taken through spout r, when desired, and returned to the other hopper-compartment. The upward incline of the rear end of the guide-bar S carried by the swingin g plate, prevents any catching or clogging of the staples as they slide down the plate and assists to seat them properly on the edge of the plate. The function of the guide-bars S and S in keeping the staples down on plates S and S has been fully set forth hereinbefore. As the bar nears the end of its upward movement the lever H is struck and actuated by the lower pin or abutment y so as to slide the hopper rearward to bring the hopper-partition R to the rear of the nose of the swinging picker S As the lower end of the magnet hammer-bar I passes up out of contact with the end of trip-lever M the holding-lever U is forced down by its spring to engage the top of the staple next to the one resting against the magnet-bar. As the end of such bar passes the series of staples it attracts the loose end staple and draws it upward with its top in contact with the lower end of the magnet-bar. The bar way or groove then keeps the staple in proper upright position with its legs in line with the travel of the bar. The holder-lever U now keeps the remaining staples from sliding down on the plate S. As the bar G continues rising the pawl M is tripped by its incline m engaging the trippin M and the plunger carrying the hammerbar is released to be driven by the force of the spring 1 This drives the staple held on the end of the magnet-bar into the shoe-sole. If the staple is of such length as to project through the sole, the inclined sides of the annular groove in the anvil E on the hornE will turn the ends of the staple-legs so as to clench them firmly.

WVith the horn supported by a strong but yielding pressure, as described hereinbefore, the best clenching action is secured, as will be understood by those familiar with the riveting or clenching of metallic fasteners.

WVith the horn supported by spring-pressure the machine can also be used for stapling shoes or other articles of different thicknesses without change or adjustment. As the bar G is being raised the pawl O rises over the ratchet-teeth thereon in position to engage the teeth and prevent any downward movement of the bar until it has been given its full upward stroke to move the hammer-plunger and the other parts connected with the bar through their required motions. hen

the bar reaches the limit of its full upper stroke, the pawl is tripped and swung back, as described, by the cam-lug on the bar, so that the latter is free to descend again.

The descent of the bar G first causes the lever T to be moved forward to allow the swinging picker S to drop, so as to bring its nose down into its lowest position. The hopper-moving lever H is then actuated by engagement of the upper pin or abutment g on the bar to move the hopperforward, causing the nose of the picker to pass through the lower end of the slot in'the hopper-partition R and penetrate into the mass of staples in the rear hopper-compartment. As the bar reaches its lowest position the pawl M is swung forward byits spring to bring its shoulder m under the arm I on the hammer-plunger, and the pawl O is, by the engagement of lug O with the end of screw 0 shifted into position again to engage the ratchet-teeth on bar G when such bar is again being raised.

To facilitate the drawing upward of the end or lowest staple on the staple-holderS bythe end of the magnet-bar, I prefer to round the lower end of guide-bar S upward and forward in cline. (See Figs. 6 and 16.) As the end of the magnet-bar attracts the top of the staple and draws it upward, this inclined or rounded end of the guide-bar will guide the staple over into the hammer-bar way to bring it squarely into line with bar.

l/Vith my machine, as described, the stapling operation can be carried on continuously as long as there is a supply of staples in the hopper or receptacle. The staple-holder or guide for guiding the staples to the magnetic hammer-bar will always be kept supplied with staples by the staple picking and delivering devices described. The picker, operating as set forth each time that a staple is and deliver to the inclined holder enough staples to provide one for each driving movement of the hammer. If it should take up staples in excess of those needed to keep the as it descends will slide off of it and drop into the forward compartment of the hopper, to be compartment when required.
