To all whom it may concern.-

Be it knownthat I, THOMAS GARE, a subject of the Queen of Great Britain, and a resident of Stockport, in the county of Chester,

' Kingdom of Great Britain, have invented new and useful Improvements in Sprigging, Nailing, Riveting, and Pegging Machines, used in the manufacture or repairing of coverings for the feet and other leather work in general, of

which the following is a specification.

Patents have been granted in the following foreign countries: Great Britain, No. 16,303, dated September 25, 1891, and No. 19,823, dated November 16, 1891 Canada, No. 41,471,

:5 dated January 9, 1893; France, No. 220,575, dated April 1, 1892; Belgium, No. 99,71 9, dated May 18, 1891; Germany, No. 69,590, dated May 4, 1892, and No.74,919, dated May 11, 1892; Austria-Hungary, No. 22,808 47,345, dated October 3, 1892, and Switzerland, No. 5,241,

dated April 23, 1892.

My invention relates to improvements in sprigging, nailing, riveting and pegging machines used in the manufacture or repairing 2 5 of coverings for the feet and other leather work-in general; and it includes the combination of devices hereinafter set forth.

Figure 1, Sheet 1, is a front View, Fig. 2, Sheet II, a side View, and Fig. 3, Sheet III, a

0 back view, of a single sprigging, nailing, or riveting machine complete, in which the sprig material is used in the form of wire. Figs. 4 and 5, Sheet IV, are front views, and Fig. 6, Sheet V, a sectional plan through line A B of 5 Fig. 4, enlarged, of the head portion of the machine; Fig. 7, Sheet V, is a front view, and Fig. 8 a side view, enlarged, of the head portion of a machine for sprigging, nailing, and riveting two rows simultaneously or alter- 0 nately one row and two rows; Figs. 9 and 10 are respectively a vertical section and a plan, and Fig. 11 a side view, and Fig. 12 a plan, of two different forms of horn or support tips for the aforesaid machines. Fig. 13,-Sheet V1, is

5 a back view, and Figs. 14 and 15, Sheet VII,

are side views, of Figs. 4, 5,. and 6.

Similar letters refer to similar parts throughout the several views.

In carrying out the various parts of my invention, in respect of sprigging, nailing and 5c riveting machines, I have in each case a suitable frame a, see Sheets 1, II, and III, in the head I) of which I mount a driving shaft 0 with a cam d, d, at its front end, see more particularly Figs. 4, 5 and 6, having a double variable stroke adapted to move the head portion 19' carrying the awl slide e, driver f and throat 9 so as to impart a variable intermittent lateral motion to the same, as described in my United States application, Serial No. 319,062, bearing date July 29, 1889.

The object it under operation, which is supported by a horn or other suitable support 1), such as is hereinafter more fully described, is fed through the intermittent movement of the head portion 1) and by the awl e, which latter may enter the object partly or wholly. The sprig or nail material I; in this case, in wire form, is drawn from a roll I a by a feed ing device consisting of a pair of feed rollers Z Z, the roller Ibeing fixed on a shaft m mounted in the stationary headportion b of the machine and at its back end furnished with a ratchet wheel m, see Fig. 13, operated by a pawl 'm carried by a lever m adapted 7 5 to oscillate loosely on the end of the shaft m through the action of a cam finger m fixed on the driving shaft-c. The feed roller Z is carried by a stud m mounted in the bearing an under the influence of a spring m which feed roller Z by means of a lever nut m may be drawn back from or permitted to exert a pressure against the wire k, so as to facilitate respectively the placing of the latter between the roller Z and Z and feeding thereof. 8 5

In order to alter the amount-of feed of the wire 70,7 6., the length of sprig to be out, an adjustable contact stud m is employed on the bearing 0, by means of which the return movement of the pawl lever m can be varied, by bringing it either nearer to or. farther away from the center of rotation of the cam finger m.

By means of the rollers Z, Z the wire In is fed into a laterally stationary guide or shear 5 piece nrendered adjustable in the head portion I) in the direction of the axis of the driving shaft 0 by means of screws 91', see more particularly Sheets VI- and VII, which piece it is fitted against the throat g and in conjunction with the latter forms a shear. On the throat or shear piece 'g having been brought into communication with the passage n of the guide piece n, see Fig, 5, and on the wire 70 having been fed the required distance into the passage n the'campart (1 moves the head part b with its throat 9 into its former position, see Fig. 4, which'causes the sprig or nail to be cut off and thereby carried over the hole previously pierced into the object it under operation and permits of its being forced into'the latterby the driver'f. The distance'at which the sprigs, nails or rivets may be driven into the material under operation may be altered as required by means of the contact piece 19 operated upon by the cam part cl and rendered adjustable on the head portion'b.

To facilitate the s ri in nailin or rivet- DD 1'" b ing of two rows simultaneously or single and double rows alternately, see Figs. 7 and 8, Sheet V, I employ two sets of feed rollers Z, Z, 1 ,5, guide or shear piece 'n with two passages n n two throats g, 9', two awls e and e and two driversfif, the outer set of feed rollers Z Z and the outer awl e being arranged to be rendered inoperative so as to bring the same in and out of action and thus leave blank 7 spaces between the inner row of sprigs or nails, as may be desired, or to form one row only. For this purpose I fit into the awl slide e a block a carr in the awl e a s rin e being placed between the block a and the awl port 5 is formed plain, as shown in Figs. 4 and 5, while for sprigging, through soles, it is formed with an interchangeable leather face 'i', see Figs. 9 and 10, Sheet V, or with a'metal face 2' having a groove '6 see Figs. 11 and 12,

which receives the ends of the sprigs and that of the awl e, one end of the said groove i being'widened so as to facilitate the spriggin g round sharp curves, such as the toe.

In order to permit of regulating the distance between one or more rows of sprigs or nails, I employ inthe upper part of the frame a, a guide 0, see Sheets VI and VII, which is rendered adjustable toward the side of the object h under operation and can be retained in position by means of a cam 0' fixed on a shaft 0 mounted in the frame a and operated by a handle 0 against which guide 0 the object operated upon is held.

The presser foot I form in two parts 19, 10',

the part p being rendered removable on the guide -0 in the upper portion of :the frame 6 by means of set screws p and the part 1)" on the guide or shear piece n by means of a screw 10 For the purpose of allowing the sprigs to project any suitable distancefrom the olrb side of the sole or heel h, so as to form a raised wearing surface, the depth of the presser foot 19,13 relative to the throat g can be altered by exchanging the pr'esser foot part 19 for a. higher i one and altering the vertical position of the presser foot part 19 by means of a taper slide p placed adjustably between the presser foot part 19 and the head portion 1).

A'further improvement consists in providing sprigging, nailing, rivetingor' pe'gging'v machines with a loose connection, see-Sheets I, II and III, between the horn lever u and respective cam lever 'v, for the purpose or ermitting the hornror support '5 to drop auto-- matically according'to the varyingt-hi'ckuese of the object it under operation-and thus-reduce the pressure thereon during the feeding q,

of the same. 'Such loose connection Iform by {suspending from the cam lever 11, from which the horn lever u is operated,a smp guided verticallyin an arm a formed on the frame a of the machine, the lower-cadet which strap 10 is lined with leather w and adapted to grip and take-with it, each'tiuie the horn or supportz' requires depressing; 1'. 6;,

on feeding, a disk or segment-meccentricaHy 1 attached to a rod a jointed to'the horn'levoru. The disk or segment a: which in diameter is slightly larger than the leather lining w, is arranged to partiallyrotate on the'end of a rod 9: guided vertically in the arin a, be-

tween the sides ofthe strap w,-so as-to alloy ii the horn or support '1: to drop according-to the varying thickness of the obj ect hunder operation. The rod 1) which connects; the strap w withthe cam lever'v is rendered adj ammo in length, so as to permit ofregnlating 'tho relative position of the strap to anddi'sk of segment 00 and thus the time of contact and. grip between the same and time of drop of horn or support 'i.

What I claim as my invention, and d'esire to secure by Letters Patent,-is-' 1. The combination ina nailing m'achineof the feed roller, the means'for opcratingthe same including-the ratchet m, the pawl m and the pawl lever m the driving-device for engaging said pawl lever intermittently for operating the same, the said pawl lever'bei-h! .held in the path of the driving devicqand the means-for adjusting the position of the lever m in the path of the operatingdevioe consisting of the adjustable studm, substantially as described.
