IMPROVED MACHINE FOR SC REWING ON THE SOLES AND HEELS OF BOOTS AND SHOES.

Specification forming part of Letters Patent-No. 37.201. dated December lti. ism-z.

To all whom i t may concern:

Be it known that LOUIS JULEs SELLIER, deceased, did invent new and useiul improvements in machines for screwing on the soles and heels of boots and shoes and other articles admitting of being screwed together, of which.

heels of shoes and boots are composed, and

also the ends and seams of straps or belts, hose-pipe, harness, and the like articles, by means of a screw which is cut in a continuous manner by the said machine, and immediately, while being cut, is screwed or entered into the material to be united and riveted thereon, thus tirmly uniting the dilTerent layers of material. The machine, such as it has been contrived after numerous experiments with a view to producing the best practical results, is fully represented on the annexed sheet of drawings, where-- Figure 1 is a full perspective view of the machine; Fig. 2, a vertical section of the headstock of the machine; Fig. 3, a horizontal sec tion of the same; Fig. 4c, a side elevation of the nose of the machine as used for belts and straps, harness, &c.; Fig. 5,a plan of the rack and cutter for severing the wire after it has been screwed home; Figsti, 7,8,detached views of the contrivance for allowingthe feed apparatus to rise and take in a fresh length of wire by opening the bisected nut or movable step in which the guide-screw works;"Fig. 9, sectional plan of another device for accomplishing said purpose; Figs. 10,11, 12, plan, end, and side elevations of holders or bearers used for uniting the ends and seams of belts or straps, and of similar articles.

In thefollowing description the same letters of reference stand for the like parts.

A is the treadle or pedal for giving the pressnrerequired for bringing and holding together the (lifi'erent layers of material in the act of screwing, theoperator putting his foot on the pedal and setting the shoe, &c., under the nose of the machine, thus allowing him to regulate the pressure according to the nature of the. material; B, connecting-rod orpitman; O, balance-weight; D,pressure-lever; E, guide; F, screw for raising or lowering the apparatus by means of a winch-handle; G, nut and slideblock; H II, standard and base for same; I I, friction-plates for varying the lateral inclina tion of the apparatus; 1, bolts screwed into the fixed plate I and working in circular segmental slots provided in the movable plate I 1', trunnion; J, dividing head or nose of appa ratus; K, head-stock; L M, tube and hollow ball for receiving the scraps produced by the chasing of the wire. The ball is made de' tachable from the tube bynieans of a set-screw for the purpose of emptying. N, lever foracting on rack for cutting off the screw; 0, pivot of said lever; P, frame; Q, bisected or open ing nut or movable step in which the guidescrew Rworks S,standard, and Sguidc-tube for conducting the wire blank S; T, bevelgear for operating the screw; U, bearing for the smooth spindle part of the hollow'guidescrew R; V, coiled spring for raising the hollow screw R whenever it is released from its nut Q; W, table of the machine.

In'Figs. 2, 3, 4;, and 5,00 is the cutter for chas ing the brass or other wire as it enters the apparatus. This cutter can be set so as to out either deep or shallow threads by means ofthe inclined slot 1) and set-screw c. d is the cutter, chisel, or graver for cutting oift'the'wire as near as possible to the surface of the screwed arti cle when screwed home. This chisel is firmly attached to the cutter-bar e, which is worked by the lever N, Fig. 1, by means ofa rack and pinion, O. The shape of the chisel a is shown in cross-section at Fig. 2, and is such as to cut off the wire in the manner of an inverted V, which causes the wire on to flatten out and rivet on the lowest layer fthe material when said end reaches and meets the iron last by the screwing pressure. The coiled springfat the rear of the cutter-oar c is for drawingback the same when the lever N is released; g, dovetail for inserting the upper part of the headstock; .h h, recesses in thenose for receiving the stamp of each preceding screw, thus acting as a guide for obtaining an equal distance between each screw and the next following.

In the machine as intended for screwing the adjustable screws l 1, so that by turning the end of the rotl I. made to enter the nut proby turning the handle 8 to the right, the not heels and soles of shoes, 850., I use a last-hold- I or, on which the last and shoe, &c.,-is fixed,as shown at Fig. 1.

i is a. movable or loose bed-plate, on which three pillars, k 7c 70', are mounted. The two outer pillars-Zr 7c", are tapped so as to fit on pillars on. these screws by means of a key, at, they may be raised or lowered to the proper height. The middle pillar, k, hasa swiveling connecting -joint, I, which, by means of its screwed end, is made to enter a not provided for that purpose in the last. The pillar k is terminated by a point or spike enteringthe last. The pillar k is terminated by a fork or cradle to receive the front part of the vamp oi the shoe. The shoe having been properly set on the twoextreme pillars 7c 7c, and t hescrewed videdin the last on ,which the shoeis mounted, as shown on the drawings, the middle pillar, k, is worked by the bevel-gear n n, provided at its lowerpart, and the shoe firtnly drawn down on-the resting-pillars k k" by screwing. The iroperinclinationis given tothelast-holder during the operation by means of a wedgeshaped piece of wood or its equivalent to be inserted under the base-plate i z. The last has to be shod with iron all round on its sole and heel part, so as to cause the screws tohe riveted, as before described.

IWhen the machine is u ed for belts or straps or other large work the front part or nose of the machine J, Fig. 1, is made longer or more projecting, as shown at Fig. 4, by placing the point 0 larther back and dispensing, if necessary, with the tube and ball L M, Fig. 1. In that case I also make the nose J convex on its under side, instead of being flat, as for screwing shoes. The holder for this kind of work is shown atFigs. 10, 1 1, 12." 0 is a smooth convex plate mounted on'a suitable standard, 7; q q, parallel rods for an adjustable guide, a- 1', to slide on.

The first mode I use for throwing the guidescrew Rin and out ot'gear, for thepnrposes hereinbel'ore stated, is shown at Fig, 9 in horizontal section. In this plan the two halves of the nut or step c o are made to swivel about a pin, 2, and opened and closed by the agency of a spring, t, cam y, and levers. Another mode for throwing the LILI'CWR in and out of gcaris shown at Figs. 6, 7, and S, and also at Fig. 1. a is a handle keyed on a spindle, t, which runs in bearings provided in thebracketa and the the first half, o, of the bisected nutor movable step c '0. Through these halves a a pass two screws 1010, the first halves, 'w u, of which are rightthreaded and the second halves, w 10, lett-threaded. Th'csc screws are set in motion by the wheel 3 gearinginto pinions .2 Thus,

or' step an is opened and the screw ltis allowed to rise suddenly under the action of the spring V, Fig. 1, in order to take in a fresh length of wire. By turning the handles to the left the not or step is tightened on the said screw R, so thatbyturning the handle T the screw R becomes active again for screwing, the fresh length of wire having previously been clamped, as hereinafter described. A suitable stop is provided on the bracket u for limiting the rotation of the handle s.

The details of construction of the hollow guide-screw R are shown at Fig. 13, re-presenting apiece of wire, S, passing through the hollowcore of the screw. Figs. 14 and 15 are elevation and plan of the collar for tightening the wire; R, screwed portion a, smooth portion, having a slot, 1), into which fits akey fastened in the boss of the driving-pinion, Fig.1; 0, hexagonal or square end of the screw, having two opposite openings, d (1, into which the clamping-pieces e e are fitted f, collar; 9, screw, which the operatorworks by means of a key for nnclatnping the wire when the whole length is screwed and clamping it again after the guide-screw R has been released and a fresh length of wire taken in; h, screw for fastening the coll'arf'; i, collar for tightening up the clamping-pieces e c. r r, Ftg.2,is an adjustable guide, fixed on the under side of the nose for regulating the distance at which the screws 4 have to be run in front the edge of the material. l

When it is desired to operate the machine. for screwing on soles the shoe is lasted as usual, the last used, however, being shod. all round with iron. in order to cause the screws to be riveted as they emerge from the sole. The last as used for this inachine-isalso provided with a metallic nut, to receive the screw 5 of the last-holder above described. The shoe or boot having thus-been secured on the last holder, as shown at Fig. 1, the screwing operation may commence. But I would here observe that for common work the shoe last and last holder may be dispensed with, and an arm may be used, having th shape of a beak-iron. A sufficient lengthfi' wire, S, having been inserted in the tube S, and clamped, the whole apparatus is set to .the proper altitude by means of the screw F and the nut and slide block G. The working end of the apparatus is then set to the proper lateral inclination by turning it about the trunnion 1' and the friction-plates I 1,'so that the screw shall enter perpendicular to the bottom of the last, whatever may bethe' curvatu e at any particular point, this variable inclination being one of the essential features of the machine. The-operator next applies the necessary pressure to the sole by pressing his foot more or less on the pedal,

A, and runs the screw in by turning the bandle T tmtil the screw meets the iron bottom of the last, which will be readilyt'elt by the operator. The pressure exerted by the nose of the machine throughout this operation is a very essential feature, as it prevents the screw separating one layer from another, and 'espe cially obviates the rising of the sole when the screw meets the last. The operator then pulls the lever N, by which the wire is cut ofl', shifts the last-holder, and continues screwing until the length of wire clamped in is used up, when 'he releases the clamping apparatus f g h, opens the bisected nut 11 'v, and the spring-V draws up the guide-screw B, so as to take in a fresh length of wire, which is clamped as before, 8:0. The operations described are continued until the whole of the sole has been sewedon.

The clamping apparatus above described may be modified in various ways, and may be made partly self acting. The scrap-receiver L M may be dispensed with entirely, and instead of the balance-weight c a spring acting upon the treadle A may be used.

Having thus described the nature of said improvements invented by said LOUIS JULES SELLIER, deceased, I claim- 1. Constructing and mounting the machine in such a manner that any required pressure may be produced on the shoe at the will ot'the operator while the screw is entering the sole, and instantly stopped after the point. of the screw touches the iron last, substantially as and for the purpose described.

2. In combination with a machine for cutting and inserting screws in boots and shoes, an elevating and depressing apparatus, as shown at F G H, Fig. 1, by means of which the machine can be elevated or depressed, as required, as in passing from the heel to the shank of the shoe, which apparatus also admits of placing the machine-in-such a position that the screw may enter the sole at any rrequired longitudinal angle, substantially as described.

- 3. Connectingtheinachinetothedepressinglever D, as shown at 1' I 1 I 1', for the purpose of inclining the machine to the rightor left, so that the screw may be entered at any required lateral inclination. 4. In combination, the elevating and depressing apparatus F G H, with the connecting-joint I l 1' I I, for the purposes set forth the screw near the sole as soon as screwed home.

8. The triangular section of the cutter 11 shown at Figs. 2, 2, and 3, leaving the lower ends of the screw in the shape of an inverted V, for the purpose of spreading and riveting on the last.
