The cam-slot 13 is made, as shown in the drawings, so as to positively move the lever 8 in opposite. directions, and thereby positively open and close the front ends of the levers or arms 2 3, which ends are provided with suitable staking-tools, herein shown as a roll 30, carried by the upper arm, and two blades 31 32, carried by the lower arm. The roll 30 may be of rubber and is journaled in brackets 33, attached to a slide-plate 34, movable in guides 35, attached to the under side of the lever 2. The slide-plate 34 may be moved to adjust the roll relatively to the blades 31 32 by a screw 36.

In the operation of the machine herein shown the carrier z' is reciprocated in the guideways h by the disk 19 through the connecting-rod 15 and depending arm 17, and during the forward movement of the carrier in the direction indicated by arrow 200, Fig. 1, the cam-slot 13 opens the jaws or levers 2 3, and during the back stroke or movement of the carrier the said cam-slot closes the said jaws or levers to effect the staking of the leather. The positive closing of the jaws or levers by the cam-slot may be assisted by a spring 40, which is compressed when the jaws or levers are opened and expands when they are closed.

In Fig. 1 we have represented the stud or roller 12 as attached to the lever 8 and the cam-plate 14: to the connecting-rod; but this construction may be reversed, if desired, as shown in Fig. 3, wherein the cam-slot 13 is formed in a plate or enlargement of the lever 8, and the stud or roller 12 is carried by an arm 45, attached to the connecting-rod 15.

The main shaft 25 may be driven in any suitable or usual manner, but in the present instance is shown as provided with a friction driving mechanism comprising a pulley 50, loose on the shaft 25 and continuously driven by a belt. (Not shown.) The pulley 50 has cooperating with it a disk or pulley 51, keyed on the shaft 50and movable thereon in opposite directions by a lever 52, pivoted at 53, and having its upper end provided with a threaded opening, into which extends the threaded end of a shaft 54, provided with a gear 55, which is engaged by a segmental gear 56, attached to a lever 57, operated by a shipperrod 58, extended toward the front of the machine and supported by a hanger or bracket 59, depending from the table f. (See Fig. 1) The link 4 of the toggle mechanism is preferably made adjustable or extensible, so as to accurately position the roll 30 with relation to the blades 31 32 when the levers 2 3 are in their closed position. The lower lever 3, as shown, has attached to it an auxiliary table or support for the leather.

The lower jaw 3 may be adjusted so as to properly position the working tools 31 32 with relation to the table f by moving the block 7 O that the two links at 5 are straight.

longitudinally on the carrier, so that the perpendicular distance from the center pin 6 to the carrier maybe varied,according to whether it is desired to raise or lower the front end of the lower jaw-carrying lever 3. By moving the slide backward or toward the left (viewing Fig. 1) on the table or carrier t' the point 6 is lowered when the toggle is operated, so Then the point 6 is raised and the front end of the lever 3 is lowered. The slot 72 in the carriert is made of sufficient length to enable the lower end of the links 11 to be carried forward a sufficient distance to throw the center point 6 to the left of the vertical line when the toggle-links 4 5 are in their straightened position, which movement would elevate the front end of the lever 3. In this manner, by means of the block 70, the tools carried by the lowerjaw or lever 3 can be accurately positioned with relation to the table.
