MACHINE FOR INS SPECIFICATION forming part of Letters Patent No. 309,081, dated December 9,188

12, 1884. (No model.)

To all whom zit may concern:

Be it known that I, SAMUEL Fl. MOWER, of New Haven, county of New Haven, State of Connecticut, have invented an Improvement 5 in Machines for Inserting Staples in Boots and Shoes and otherArticles, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

In the manufacture of shoes, especially of that kind'known as buttoned shoes, there is very considerable strain at the junction of the button-hole piece and the vamp. So, also, in laced shoes the strain is very considerable r 5 at the junction of the quarters and vamp.

These points, which are subjected to the greatest strain when pulling the foot into the shoe,

are now commonly provided with stays, produced by making a number of stitches back and forth, or by using a larger thread or cord, or by employing a rivet, as in the cheaper class of shoes known as brogans.

My invention has for its object the production of an automatic machine for inserting a staple into the uppers or Vamps of boots and shoes, to constitute stays, the mechanism here in shown as embodying my invention being adapted to make its own staples.

Figure 1 is a side elevation, partly in sec tion, of a machine embodying my invention; Fig. 2, a front elevation of the canrdisk which operates the driver and the feed-actuating mechanism, the said figure showing the link to be attached to the driver, the studs for lifting the driver and presser-bars being shown in section; Fig. 2, a sectional detail below the line 00", Fig. 1. Fig. 3 is a front elevation of the machine shown in Fig. 1; Fig. 4, a de tail, to be described. Figs. 5 and 6 are details representing the front of the machine, the face-plate and the pivoted former being removed, the presser and driver being in different positions. Fig. 7 is a longitudinal vertical section of most of the parts of Fig. 5, part of the former over which the wire is bent into staple shape being added. Fig. 8 is a detail to illustrate the presser and its action, and Fig. 9 is a detail showing part of the left side of the presser to illustrate the fixed but adjustable member of the wire-cutter.

The main frame A of the machine, support- :ed, as herein shown, upon a column, 13, contains the main shaft (1, which is provided with suitable clutch parts, a a", under the control of a lever, a", and a rod, a, extended to a suitable treadle, whereby the said shaft may be rotated once and then stopped, as is commonly done in boot and shoe nailing machines. The main shaft coat one end is provided with a disk, 0, secured thereto by a suitable key or feat-her, and provided at its rear side with a cam-hnb, c, and at its front face the said disk is provided with a cam, 8, made as a groove. The camgroove 8 receives a rollerstud, f, connected, as shown in Fig. 1, with the presser-bar f, which is fitted to slide in suitable guideways made in the head A removably attached by suitable screws to the flange A of the frame part A. This presser is recessed longitudinally at its front side, and at its lower end has applied to it a plate, a, (see Figs. 5 and 6,) so as to leave behind the said plate a space or throat, 54, through which to drive the staple into the work. Above this plate a the said presser has secured to it two side plates, ntwhich are applied to the presser fby screws 53, so as to projectjust below the curved or beveled lower ends, 52, of the side walls of the presser, (see Fig. 8,) the same being cut through to form a space, 20, for the reception of the wire 34., as will be described, the said ends 52 constituting staple bending surfaces to co-operate with the former min the formation of the staples, as shown in Fig. 8, wherein it will be understood that the central part of the staple s is held in the notch at the lower end of the former and that the presser is descending, the figure showing the presser as having been depressed sufficiently far to permit the end of the short piece of wire to be drawn out of the groove 20, thus completing the staples, ready for thedescent of the driver i, as will be described. The upper end of the plate a is notched (see Figs. 5, 6, 7) for the reception of part of the lower end of the former m, (see Fig. 7,) pivoted at 22 011 the face-plateg of the head A, the said former being notched transversely at its lower end at m (seen best in Fig. 7,) and provided at its upper end witha too, 23.... (See Fig. 1.) The presser at its lower 0 end is slotted verticallyfor the reception of a spring-latch, 10, attached thereto by a screw,

21, and the said latch has an inclined face above its shoulder. The disk 0 has a pin, 26, onwhich is placed a link, h, provided at its upper end with a pin, h, which is extended through the driver bar or carrier 1', (see Fig. I will first be moved back far enough to wedge 1,) fitted into a groove, 44, in the head, (see Fig. 5,) the driver z" being placed in a groove, m, in the driver bar or carrier, and over a pin, 28, in the said bar or carrier, so as to be reciprocated in unisonwith it. The driver 2" is shownas a flat but stiff steel bar, which passes behind the edges of plates a into the space 54 behind the plate at in the lower end of the driver, and is, preferably, concaved or countersunk to fit the crown of the staple s to be driven, the said link and pins and disk actuating the driver positively as the shaft a is rotated. The pressery slides between guide plates or ways 9 9, attached to the head of the machine by screws 29. The upper end of the driver-carrier is made cam-shaped, or is provided with a beveled steel plate, as shown at 25, Fig. 1, to act against the toe 23 of the former m. The wire-guiding block 9, attached I to the head of the machine by the screw 30,

extended through a slot, 31, therein, so as to provide for adj ustment' of the said block, has its groove placed opposite one of the notches 32 in the notched disk or plate 33, of steel, placed in a recess in the left side of the presser, and arranged therein and held by a screw, 56, next the inner end of the grooved block 9, the inner corner or end of the said block and the said disk or plate forming the cutter members for severing the wire. The edges of one of the'notches of the disk 33 becoming worn, the disk may be turned, thus bringing another notch into operative position. Thelegs of the staples to be formed 7 and driven, as will be described, are clinched upon an anvil, 12, having two concavities. (See Figs. 1 and 5.) The anvil is held in an anvil-block, 13, by a screw, 45, and the shank of the said block is extended down through, preferably, an india-rubber block, 46,'and a hand-operated nut, 47, screwed into the socket '14 of the bed 15, one or more set-nuts, 48, be-

ing placed upon the lower end of the said shank. The rotation of the nut 47 in one or the other direction enables the anvil-block and anvil to be raised or lowered, and the india rubber block, or it might be a spring, enables the anvil to have a limited amount of yield to the stock. Instead of said india-rubier block or spring, I may employ a metal collar. The

I wire is fed forward by a feeding device comprised, as herein shown, of an arm, (1 having an attached block, (i a spring-held annulus, d, and a wedge-block or annulus holder, d The annulus is placed over the hub e of a washer, e connected by screw 40 with the arm (1 a pin, 4l,.preventing the hub from being rotated on the said pin. The inner diameter of the annulus is considerably larger than the external diameter of the said hub e, and a spring, 42, connected at one end to the said hub, and placed between the said hub and annulus, as shown in Fig. 4, tends to keep the annulus in such position that'as the arm at is moved in the direction of the arrow in Fig. 3 the annulus, by the action of the wire,

itself under the inclined lower edge of the serrated block or holder d which latter will engage the serrated edge of the said annulus, thuscausing it to bite the wire closely between it and the block d, and thereafter the wire will be carried forward with the arm 01*,- but as soon as the arm d is moved in the opposite direction the annulus resting against and biting the wire will instantly draw the annulus forward, or. away from the lower end of the holder at", and the disk and block (1 will travel easily backward over and without moving the wire; but at this time the wire will be held by a like annulus mounted on a like hub attached to a fiXe(l'-arm,--5, of the head or face plate, (see Fig. 3,) the said annulus (herein marked 46, to distinguish it from the one d") operating in connection with a block, -6, and a holder, 6 the same in construction as parts marked d and d before described, they constituting a detentfor the wire, and preventing the same from being moved backward from any cause as the arm d of the feeding device is moved backward.

I do not limit my invention to the particular devices for grasping the wire as described, and instead thereof may use any other wellknown equivalents: The arm dis attached to a rock shaft, (I, mounted in a bracket, d, attached to the head of the machine. The rock-shaft d has attached to it a second arm, 0 which by the spiral spring d is kept pressed against the feedactuating slide 0", provided with a roll, 0", (shown in Fig. l and in dotted lines, Fig. 3,) which latter is, by the said arm and spring, kept pressed against the cam-hub c referred to, the latter, as the shaft a is rotated, vibrating the arm d a greater or less distance, and consequently feeding the wire more or less at each forward stroke. The extent of movement of the arm d is regulated by the feed-regulating screw or device d held and made adjustable in an ear of the arm (1, (see Fig. 3,) the said screw co-operating with the projection d fixed to the bracket (1.

Assuming the parts to be in the position shown in Fig. 5, which shows the wire 34 about to be passed across one of the plates n" at the face of the presser-bar f, and the driver 1" about to force a previouslymade staple (shown in full lines in the lower end of the presser-bar) down into the stock supposed to be resting on the anvil 12, the operation of parts, upon giving motion to the shaft a by clutching it to the pulley a through the aid of the foot-lever, (not shown,) will be as follows: The feed-leverd through the operation of the connected parts, will be moved toward the cutter-bar 9, in the direction of the arrow thereon, Fig. 3, and, gripping the wire, will draw it from the spool 3 through the grooved rod 1', and between the annulus 46 and block 6 of the detent, as described, and will force or push a portion of the wire held by and in front of the lever d through the block 9 and across the face of the presser-bar IIO f and the driver 13 and into the groove m of I with means, substantially as described, for

the former or lever m,when the disposition of parts will be substantially as shown in Fig. 1. While the wire is being fed across the face of the presser bar and into the groove on in the lower end of the former 'm, the driver t" is forcing the previously-made staple through any suitable shoe or other article held on the anvil; which done, the presser-bar will be drawn up into the guides until the transverse groove 20 is brought immediately back of and in line with the portion of the wire held by the former m across the face of the presserbar, at which point the driver-bar 12, carrying the,driver i, having been partly drawn up in its guides, is carried to its highest point in said guides, and its beveled upper end, 25, strikes against the toe 28 of the former m, (see Fig. 1,) thus turning the former m to force its lower end, yet holding the wire, toward the presser-barf, and as the driver at such position of the driver .bar or carrier is sufficiently elevated to rise above the groove 20 referred to the wire acted upon by the former m ispushed into the said groove 20 of the presser-bar (see Figs. 6 and 7,) and is held therein by the former. This done, the presserbar will begin its downward movement, whereupon the disk-cutter 33, operating in connection with the end of the block 9, will cut or sever the wire of a proper length fora staple, and the curved or inclined portion 52 of the descending presser-barf, acting as wipers on the ends of the said section of wire fixedly held by the notch m of the former m, will effeet the withdrawal of the short piece of wire from the groove 20 at each side of the former, producing a staple, as shown in Fig. 8, which will be held in the groove in the path of the driver, so that the driver in its descent will strike the staple. The spring 10 in the groove in the face of the presser-bar acts against the staple after the lower end of the former m is thrown out and prevents the staple from tipping over.
