VISE.

SPECIFICATION forming part of Letters Patent No. wasaauated October 18, 1904. Application filed February 20, 1904. Serial No. 194,487. (No model.)-

first be fully described and the features of noveltythen set forth and claimed.

Figure 1 represents a side elevation of a vise to which I have applied my improvements. Fig. 2 is a top plan view of the same. Fig. 3 is a detail side elevation of the anviljaw from the side opposite to that shown in Fig. 1. Fig. 1 is adetail elevation in partial section of the movable jaw and detached parts. Fig.5 is a detail elevation of one of the jaws- Fig. 6 is a plan and side elevation of a hardy upon one of the jaws.

In a preferred form of my invention I pro v-ide'a plate 1, adapted to be screwed to the side of a work-bench 201' to any other suitable point of support, such as the side of a forge or the like. a movable arm 3, carrying the movable jaw 5. Rigidly secured to plate 1 is an arm'6 carrying the stationary anvil-jaw 7.

8 is a lever pivoted at 9 to the arm 6, the opposite end of said lever 8 having pivoted thereto a pull-rod 10, extending downwardly, where it is pivoted to a foot-treadle 11 at 12. This foot-treadle is pivoted at 13 to a downwardly extending arm 14:, rigid with the main plate 1, being attached thereto or formed integral therewith. 'The outer end 15 of treadle 11 may be pivoted at 16, so as to be thrown up out of the way whenever it is not desired to use the treadle. 4

17 is a: spring for normally throwing the yoke-link 19, having the open end thereof embracing opposite sides of the link 8 and eX- Pivoted at 4 to plate '1 is tending upon both sides of the anvil-arm 6 and the armj3 of the movable jaw. At its end opposite the pivot 18 it is provided with an adjusting-screw and handle 20, the end of the screw taking into a recessformed in the arm 3 and threaded through an aperture in the link 19, by means of which the movable jaw 5 can be adjusted to and from the jaw 7.

The link 8 is provided with a rack or series of notches 21, and the stationary arm 6 is provided with a pivoted pawl 22, having a springretracted operating-arm 23, whereby after the link 8 is actuated the pawl 22 may engage the same and lock the link in its adjusted position.

2 1 is a spring for normally retracting jaw .55 from jaw 7.

This construction embodies a combined foot-andhand-operated device.

If it be desired to clamp an article, as 25, between the jaws 5 and 7, the foot is placed upon the treadle 15, which causes the downwardmovement of the pull-rod 10 and also the pivotal depression of the link 8. latter link being pivotally connected with the yoke 19 acts as a compound lever to force the link 19 to the right in Fig. 1. Thislink, carrying the adjusting-screw 20, forces the movable jawtoward the stationary jaw 7 and effects a preliminary clamping of the block 25. The handle 23 is now operated tothrow the dog or pawl 22 into engagement with the rack 21 on the link 18 when the foot-lever is released, the parts being thereby locked. The handle of the screw is now rotated in the ordinary manner, completely and effectively clamping the block between the jaws. The block is released by rotating the screw in the opposite direction and pressing on treadle 15 sufliciently to allow the spring-retracted pawl 22 to disengage itself from the rack 18, when the jaws will open by the spring 24: as far as the screw 20 will permit.

This

This vise is peculiarly adapted for calking horseshoes. I

The anvil-vise 7 between the clamping-jaw and the hardy 26 is provided with a series of parallel V-shaped notches 27, extending clear across the face of the anvil. These notches are used in welding toe-calks. The movable jaw 5 also is used for anvil purposes. side 28 of the top face of this jaw is beveled somewhat, as shown in detail, for the purpose of forming sharp heel-calks. The balance 29 of the top surface of this jaw is reserved for the making of blunt heel-calks. Aspecial hardy 26, as shown in detail, is especially adapted for trimming shoe-heels.

What I claim as new, and desire to secure by Letters Patent, is

In avise, the combination of a supportingplate located substantially midwayof the vise structure, an arm depending downwardly from and supported by said supporting-plate, means on said plate for attaching it vertically to the side of a frame, a rigid arm and jaw secured to the upper side of the plate, a movable arm and jaw straddlingover and One pivoted to the upper side of the plate alongside the rigid arm, a link pivoted to the rigid arm and jaw, treadle connections secured to the depending arm supported by the midway plate and connected to said link, a yoke-link pivoted to the first link, an adjusting-screw upon the yoke-link bearing against the movable jaw, a rack formed upon the link which is pivoted to the rigid arm and jaw, and a pivoted pawl upon said rigid arm and jaw engaging the rack.

ln testimony whereof l have afiixed my signature in the presence of two witnesses.
