IMPROVEMENT IN MACHINES FOR UNITING THE UPPERS AND SOLES 0F BOOTS AND SHOESH Specification forming part of LettersPatent No. 169,463, dated November 2, `1875; application..filed` May 15, 1875.

To all whom it may concern:

Beit known that We, GORDON MCKAY, of Cambridge, Middlesex county, andHADLEY P; FAIRFIELD, of Boston, Suffolk county, all inthe State of Massachusetts, Ahave invented jointly an `Improved Machine for Unitingthe Uppers and Soles of Boots and Shoes, `of which the following is a specification:

This invention relates to mechanism for uniting the uppers and soles of` boots and shoes,

v is an improvement on other machines heretoforeV patented by us,`and the mechanism hereindescribed is to be used in connection with a:shoesupport and properfeeding/mechanism for moving the shoe, and for these mechanisms we prefer as the support a curved salient horn or arm, and feeding mechanism shown in United `States Patents Nos. 122,985 and 140,400, but we might employ any other Wellknown feeding mechanism. u

The horn and feeding mechanisms, not being a part of this invention, are not represented in the drawings, as they are fully described in the patents above cited, and are shown in the well-known McKay sewing-machine.

In machines using nails cut from wire-like material it is common to cause the length of the nail to vary automatically by the variation in the thickness of the sole or soles.

In this machine, instead of awire we employ a at strip of metal from which the nails are formed. The strip being of a Width equal to the length of the longest nail desired, and fed through the strip-guiding` tube, it is cut into nails, and each nail is forced into anaiLguiding channel, where it isV corrugated by dies or compressors operated from the cam-shaft by a pivoted lever, and then the nail is movedlfor- Ward supported at its point on a movable rest,

and placed within the line of movement of the.

head-cutter, which is carried in ways in the reciprocating or sliding head which carries the nail-driver and nail-guiding tube, and which adapts itself in its lowest position to the thickness of the material into which the nail is `to be driven. This sliding head is adapted to rise and fall in guides in the framing, and carries the nail-guidin g tube and head-cutter, and in` line with the nailfguiding tube is the naildriver, it being steadiedby suitable` guides,

The sliding head israisedfrom thework prior to each feed movement of the shoe, torelease the shoe from pressure,4 and to allow it to be `moved easily by a Acam ou the main shaft through a leverwhich engages a friction-.roller or other projection on the sliding head, andthe sliding'headafter thev feeding movement has taken placeis thrown down by a suitable spring until the nail-guiding tube rests on'pthe sole.` In this position thenail-restislmoved forward within the open side ofthe nail-guiding tube,thereby supportingy a nailL in the tube in the'pathof the nail-head cuttenwhichis then thrown forward, andcutso` the headof the nail more or less, according to the position of the sliding head andicutter,.and `in thisway the corrugated nail is cut to correspondLwith the thickness of the materiahthey projecting through the inner. sole only just far enough to meet or clinch. a litt] el against the iron support. This strip fromv which the-` nails-are lout Vwill preferably'have a groove near-its point-forming edge` to weaken thelpoint of the. nail so that itwillrreadily turn and form aqzclinch. The nail-driving mechanism,.orthat. which operates the driver, is operated through azwalking-beamv or a lever, andV by a toggle-jointed connection or link,.aslin United States Patent N o. 155,962, andneedvnot, therefore,be herein described, as such devices operate. inthisas in the machine described in such patent. l

Figui-er1 is a topview, partially in section,

^ of thisl our improved mechanism. Fig. 2 is a front. view;` Fig. 3, a detail of the nail-guiding tube and movable rest for the nail, thelatter being` in position to sustain anail whilelits head is being cut off by the headfcutter.` Fig. A is a side view. Fig.5 is a back View` ofthe sliding head and nail` guiding tube and headcutter, and Fig. 6 is asection takenA through the strip-guiding tube. e y A is the frame ofthe machine, of"` any suitable shape to sustain the workingparts, and provided with a shaft, a, having ady or band wheel, al, and with cams b b1?)2 c 4c1 c2 d. An arm, d1, pivoted at. d2 tothe frame, and with one end resting under therolleiwor projection e of the sliding head e1, guided inzways c2, is struck by cam d at each revolution of `the shaft c, so as to raise the. sliding head c1 and 2 mense the nail-guiding tube fand head-cutter-guiding box f1 prior to each feed-inovement, and the sliding head is allowed to drop so that the tube f rests on the sole after each feed-movement. be cut is placed in 'the strip-guiding tube f2,

' and is fed forward in such tube by a pawlmoved by the cam b2 on the main shaft. The :cutter i has opposite it a stationary cutter, jz,

and as a nail, la, is cut from the strip f2 it is moved toward the nail-guiding tube, the drawing, Fig. 1, showing la number of such nails -so cut off and moved at right angles to the movement of the strip, each nail acting against the other. When the nails come between the corrugating-dies k1 such dies, having corrugated and concaved faces suitably shaped, are

caused to move against the `iides of the nail and press it into somewhat c ral form, and corrugate or nick it. These dies are held in a lfixed portion of the frame, and are caused to approach each other through the action of projections .cv on a lever, k2, made to turn about the hub Z, (shown in section, Fig. 1,) and moved by a cam, c2, on shaft a. After the nail is corrugated it is passed along in the nailguiding channel and through the hub l. The bottom of the nail-guiding channel is formed by a movable plate or rest, l1, (see Figs. 1 and 3,) which is reciprocated by a pivoted lever, Z2,

operated by cam con cam b1, the forward end of the lever having an inclined actuating face,

and entering a slot in the rest il, so as to move i it forward and back at the desired times, the

lever Z2 being moved in one direction prefera. bly by a spring'. The forward end of this rest forms a shelf for a nail, and when the rest is thrown forward it passes within the nail-guiding tube f, as shown in Fig. 3, and there supports a nail, the tube being open at its side for suchv purpose. Therest has no vertical motion, and is lstationary with relation to the in- 11er surface of the shoe-sole, and as the sliding head, by the action of the nail-guiding tubeon the sole, is raised or lowered, with re- 'flation to the shelf, the head-cutter m, carried by the head e1, will be raised more or less above the shelf l1, and the point of the nail and the headcuttermin its forward movement,

, actuated by the face-grooved cam b, through forced out through the channel m2, Fig. 5. yThehead of thenail being cut off, the shelf l1 is Withdrawn, the nail drops into the tube j',

y it being prevented from moving back by the The strip from which the nails are to nails standing back of it, and when drawn back the projection n on the shelf or rest ll closes the side of the tube f, and prevents the nail from falling out. The nail-driver 1" then operates in the usual way to drive the n'ail from the tube f into the sole. The stationary cutter nl, against which cutter m works, is made adjustable by means of the screws n2 o, Fig. 4. The nails fed into the tube fare not always of the same thickness, and therefore it is not safe to crowd the cut-off nails from the tube f2 against a rigid portion of the sliding head e1, and to prevent any damage from the' accumulating nails, and to keep them held properly together, we place in the sliding head el, and opposite the passage through which the separate nails move, a spring-supporting plate, o1, having a shank, 02, surrounded by a spiral spring, one end of which bears against o1, and the other against a nut, p, screwthreaded, and turned into the sliding head, the nut governing the force of the spring. The cutters and feeding devices are adjustable as to their movements.

-With this our invention strips of wood such asare commonly used in pegging-machines may be used instead of metal; but we prefer metal.

To properly sever a nail, 7c, from the strip, the cutterz' should move sufficiently far forward to pass its cutting-edge beyond the opposite side of the strip, and in so doing all the severed nails are moved forward for a distance greater than the lthickness of the nail last severed. During this movement the outer nail 7c is pressed against the spring-supporting plate o1, and when the cutter i is drawn back the spring about the shank o2 presses back the plate o, and with it the nails, leaving the nail at the outer end of the shelf 'll in position to be driven by the driver r.

Having described our invention, we claiml. The combination of the strip-guiding tube and cutter for severing the nails, with the movable dies for corrugating the nails after they are cut from the strip, and in their passage to the tube and driver, substantially as described.

2. The combination of the movable nailguiding-tube and the rest or shelf, adapted to support a nail within the tube, with the headcutter to out the nail to the required length, substantially as described.

3. The combination, in a nailing-machine, of mechanism for cutting nails from a strip, mechanism for corrugating the nails cut from the strip, and mechanism for supporting and cutting each nail just prior to its being driven to a length corresponding to the thickness of the sole, substantially as described. I 4:. The combination of the strip-guiding tube and nail-cutter with the movable rest for the severed nails, substantially as described.

5. The combination of the movable slide and Vnail-tube, variable in position, according to the thickness of the sole of the boot or shoe, and its head-cutter, with the rest for supporting the nail while being out, and with the naildriver, substantially as described.

6. The combination, With the strip-guiding tube, of a cutter adapted to out a nail from the strip and move it into a nail-guiding pzissage, substantially in line with the path of the eutters movement, as and for the purpose set forth.

7. The combination of the cutter fi, adapted to sever the nails from the nail-strip and move them forward in the neil-guiding passage, with the spring-supporting plate o1, substantially as described.
