To '00 whom it may concern:

- Beit known that I, ISAl'E FREOHETTE, a citizen of the Dominion of Canada, residing at the city of Montreal, in the district of Montreal and Province of Quebec, Canada, have invented certain new and useful Improvements in Hand Lasting-Tools; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to hand lasting-tools; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

view of the shoe P.

A and B are two levers provided with jaws A and B and handles A and B These levers are pivotally connected by a pin Y. A spring y encircles the pin Y and is inclosed in a hole in the lever B. One end of the spring y engages with a hole in the lever A and its other end is secured to the disk y.

The disk y is provided with a projection M,

which engages with slots y, the tension of the spring being adjusted by turning the disk before securing the disk in position. A screw y is provided for holding the disk in position. A washer 1 is secured to the said disk.

The lever B has a lug b on its under side, which is provided with a slot b A shoe l) is slidable upon the lug b, and b is a pin which passes through the shoe and is slidable in the said slot. The shoe is slidable on the lug, and b is a spring (see Fig. 14) which presses the shoe away from the'jaws. The under surface of the shoe serves as a fulcrum, which rests on the inner sole when the edge of the upper is gripped between the jaws and the handles are pressed downward, so as to stretch the leather. ward in the shoe when the tool is pulled backward to stretch the leather. The shoe 1) can also be used as a hammer.

The leverAis provided with a socket c, in which a plunger 0 is free to slide vertically. The plunger 0 carries a steel nail-driver c at its lower end, which slides in a hole q in the jaw A. The upper part of the plunger is provided with a flange c and an extension 0 above the flange. A guide-rod c is secured in the lug a on the upper part of the socket c, and the said flange is provided with a hole which slides over the said guide-rod. A lifter-bar c is pivoted by a pin in a hole in the flange 0 so that it can oscillate back and forth, and this lifter-bar is provided with a shoulder c on its rear side. slides vertically in a guide a on the lever A between the lugs a D is a curved plate the upper end of which is secured to the said lugs by the screws (Z d and which forms a cover for the guide. The lower end of the plate D is secured to the lever A by a screw (1 E is a pawl which is pivoted 0n the pin 61 and which is pressed against the lifter-bar by a spring 6'. The spring 6 is secured to the screw cl, and its free end bears against the projection e on the pawl.

G is a spring secured to the lever A by a pin 9 and to the upper part of the plunger 0 by a pin 9 and passes through a hole in the flange of the plunger.

F is the lever for raising the plunger. This lever is pivoted to the lever A by a pin f, and it is provided with'a slot f with which a pin The lug 2) slides back- The lifter-bar f on the lever B engages, so that the hooked end f of the lever F is raised when the handles are pressed toward each other. The said hooked end engages with the shoulder a and raises the lifter-bar and plunger. A roller d is journaled in the guide under the screw (Z, and when the lifter-bar is raised its inclined rear side bears against this roller. The roller forces the lifter-bar forward, so that its lower end slips onto the top of the pawl and the shoulder disengages itself from the hooked end of the lever F. The pawl is prevented from being moved backward too far by the projection 6 which rests against the curved plate D. When the plunger is thus raised and supported by the pawl, the jaws can be moved back and forth and the tool can be used for stretching the leather without affecting the said plunger.

The stroke of the plunger is regulated by means of the thumb-screw S, which has a flat stem. This thumb-screw has screw-threads s, which engage with the flange on the plunger, and it is held in position by a spring .9, which is secured to the extension of the plunger and bears against the said flat stem. The lower end of the thumb-screw has an eccentric projection .9 When the thumbscrew is turned so that the projection will strike the lug on the top portion of the socket c, the stroke of the plunger is shortened, but when the projection descends clear of the said lug the full stroke of the plunger is assured. The change between short stroke and long stroke is effected by a partial turn of the thumb-screw, and the length of the short and long strokes can be regulated by turning the thumb-screw.

In nailing the uppers around the heel portions of the inner soles it is not necessary to stretch the leather by means of the jaws, and a presser-piece V is provided. The presserpiece V is pivoted by a pin 12 to a lug 'u on the jaw A, and it is provided with curved ends '0 for holding the upper firmly down over the heel. hen in use, this piece V is folded down below the jaws, as shown in Figs. 7 and 16, but when not in use itis folded up, as shown in Figs. 6 and 14.

The lasting-nails O are formed continuous with each other and are wound upon a reel 0, which is j ournaled on a pin projecting from the lever A. These nails pass down the guide 0 in the lever A and are pressed against the upper part of the said guide by the T-shaped shoe P. (See Figs. 9 and 18.) A block 10 is secured in a chamber in the said lever adjacent to the said guide, and the part p of the shoe 1 is slidable in a hole in the said block. A spring 1) is secured to the said block and presses the shoe against the nails.

N is the feed-pawl, which is pivoted to the adjustable arm on. The arm on is carried by the lever M, which is pivoted on a pin i, projecting from the lever A. The arm m forms an extension of the lever M, and it is pivoted to it by the pin m The arm 071 has a curved slot m and m is a screw which passes through the said slot and secures the said arm after its position has been adjusted to make the point of the feed-pawl descend to the exact position required. The point of the feed-pawl is pressed into engagement with the nails by a spring or, attached to the said pawl and to a projection on the lever M. The feed-pawl is prevented from being raised too high by means of a stop-plate n, arranged in its path and secured to the block 1). This stop-plateis adjustable and has a slot through which its clamping-screw is passed for securing it to the said block.

I is a lever which is pivoted to the lever A by the pin 1' and is provided with a handle t for operating it.

H is a spring the upper end of which is secured to the extension of the plunger 0 by the screw h. The lower end of the spring II is secured to the lug h on the lever I, and the spring holds the said lever in its raised position. A jaw 2' is formed on the lever and slides upon the guide-rib t", which projects from the lever A. A tappet 2' projects from the lever I and strikes the projection e on the pawl E just before the lever I is pressed down to 'its lowest position. This tappet pushes the pawl from under the lifter-bar and permits the descent of the plunger.

K is a toothed segment pivoted on the pin 7; and gearing into the toothed segment L, which is pivoted on a pin projecting from the lever A. The segment K has a slot with which a pin is, projecting from the rear end portion of the lover I, engages. The segment L carries a roller Z, which bears against the upper side of the front end portion Z of the lever M and depresses it when the lever I is pressed down by hand. A spring m is provided for connecting the rear end portions of the lovers I and M. When the lever I is raised by the spring H, the spring m raises the front end of the lever M, together with the feed-pawl N, and the feed-pawl engages with another nail.

J is a lever which is pivoted to the lever A and has a cutter Q secured on its side. The cutter Q, works in a recess in the jaw A and cuts off the nails, as shown in Fig. 12. The lever I has a projection 1?, (shown in dotted lines in Figs. 2 and 8,) which engages with a projection j on the lever J and turns the cutter back to the position shown in Fig. 11, when the lever I rises and leaves it in that position, the projection on the lever 1 continuing its upward course. WVhen the lever I is depressed, the projection i engages with an arm or projection j on the lever J and operates the cutter, so as to cut off a nail, as shown in Fig. 12. As soon as the nail is cut off by the cutter the driver 0 strikes its head, and the continued downward movement of the plunger 0 drives in the nail down the channel q into the leather.

The lever J has a slight projeetionj on its front side, and j is a spring secured to the lever A and bearing on the said projection, so as to provide a slight frictional resistance to the movements of the said lever and cutter.

R is a stop depending from the flange c WVhen the plunger descends, the stop R passes behind the tappet 2' and remains in its upward path, as shown in Fig. 1, so that the feed-pawl cannot be raised until after the plunger has been raised by the lever F, so as to raise the stop R. 1
