TOGGLE.

Application filed December 16, 1922 Serial No. 607,334.

T 0 all 1/:h0mit'ma3 concern:

Be it known that I, CHARLES S. ,MORRP" sorz. a citizen of the United States, residing in lllkins Park, Montgomery County, Pennsylvania; have invented certain Improvements in. Toggles, of which the following 1s a specification.

One object of my invention is to construct a toggle, which is used for securing leather to frames during the process of manufacture, the toggle being fashioned so that it can be clamped readily and firmly to the leather.

A further object of the invention is to design the toggle so that it will accommodate itself to different thicknesses of leather.

In the accompanyin drawings:

Fig. 1 is a perspective view of my improved toggle; 1

Fig. 2' is, a sectional View, showing the toggle in the open position; l ig. 3 is a sectional view, showing the toggle clamping a thin piece of leather;

Fig. 4 is a view, similar to Fig. 3, showing the toggle clamping a thick piece of leather; and

Fig. 5 is a sectional view on the line 5-.5, Fi g. 2.

Referring to the drawings, 1 is the body of the toggle made of a single piece of spring metal. 2 is the back plate having a hook 3 pressed from the metal of the plate and bent. as shown, to engage the wire of the supporting frame on which the leather is 4 is the lower tongue,'which is bent. as shown, and is prot ided with a serrated gripping surface 5 and an outturned end 6 that comes in contact with the inner surface of the upper tongue 7. The tongue 7 forms a continuation of a spring portion 8. The tongue 7 overlaps the tongue 4- and is perforated,.in the present instance, at 9, opposite the serrations 5, forming a gripping surface. The perforations allow the heated air to come in contact with .the

portions of leather held by the toggle. In some instances, the tongue 5 may have perforations instead of the serrations and the tongue. 7 may have serrations instead of per forations. The shape of the clamping portions of the tongue may be varied, as desired.

A post 10 is shaped as shown in Fig. 2, and has an'arm 11 projecting at an angle from its outer end. The post extends through a slot 12 in the tongue 4. and a pin 13 extends throughthe post back of the tongue and acts as a pivot for the post- The post also passes through a slot 14 inof the tongue, when the lever is turned to the position shown in Figs. 3 and 4.

The arms 18 have rounded lateral pro- -jections, which give the lever an extended bearing on the tongue 7.

It will be noticed that, when the lever is turned from the position shown in Fig. 1

. to that shown in Fig. 3, the ends of the arms18 pass a line mw drawn through the two pivots 13 and 16, lgcking the lever in the clamping position. This movement brings the ends 19 of the arms of the lever directly in front of the gripping surfaces of the two tongues so that the material being clamped is held positively, while the post rests against the shoulder 15.

improved toggle will accommodate itself to thin or thick materials. v

In Fig. 3, the toggle is shown gripping a thin piece of leather.

In F ig. 4, it is shown as grippinga thick piece of leather. The tongues accommodate themselves to the material when the lever is turned.

When the lever is turned to the position illustrated in-Fig. 3 to clamp the leather, the end 6 of the tongue 4 bears against the tongue 7, as clearly shown in said figure, which causes the toggle to grip the leather firmly. The edge of the post bears against the shoulder 15 on the tongue 7. This bearing point is a fulcrum for the post in its movement from the open to the closed position.

By having a thin, centrally located, post, and the arms of the lever bearing on the tongue 7 at each side of the post, the tongue is free to accommodate itself laterally to the leather clamped between the ton ues.

My improved toggle istused particu arly for holding leather to a frame during the drying process. although it may be used for holding leather during other processes of manufacture. The toggle can also be used for holding fabrics, and other materials, while being dried.

In one process of drying, a frame having a series of cross wires is used, and the toggles are clamped to the edges of the leather and are hooked onto the wires. As the hooks are at the rear of the toggle, the leather is kept some distance from the supporting frame.

I claim:

1. The combination in a toggle, of a body portion having a tongue at each end and bent so that one tongue overlaps the other tongue; a postpivoted to one tongue and extending through the other tongue; and a lever pivoted to'the post, said lever, when turned causing the tongues to move towards each other and clamp material between them.

2. The combination in a toggle, of a body portion having a. tongue. at each end, the tongues being bent so that one tongue overlaps the other tongue, both tongues being slotted; a post extending through the slots in the tongues; a pivot pi holding the inner portion of the post to one tongue; and a lever pivoted to the outer portion of the post and arranged to bear upon the other tongue so that, when the lever is turned, the two tongues are drawn towards each other, clamping material between them.

3. The combination in a toggle, of a body portion having a tongue at each end, one tongue overlapping the other tongue, the overlapping tongue having a spring portion both tongues having clamping faces; a post extending through both tongues; a pivot pin for the post back of the inner tongue; and a lever pivoted to the outer end of the post and arranged to bear upon the surface of the outer tongue, the end of the inner tongue bearing against the outer tongue when the 7 two tongues are drawn towards each other by the lever so as to act as a fulcrum for the outer tongue as the material is clamped between the two tongues.

4. The combination in a toggle, of a back having arms arranged to draw the tonguestogether, when turned, the post fotating on the pivot of the inner tongue toaccommodate itself to different thicknesses of material.

5. The combination in a toggle, of a body portion having a tongue at each end, one tongue overlapping the other tongue, both tongues being slotted; a ost. extending through the slots; a pivot pin for the inner end of the posts; and a lever having two arms extending, one on each side of. the post and arranged to bear upon the tongues.

6. The combination in a toggle, of a body portion having a tongue at each end, the itongues being bent so that one tongue overlaps the other tongue; a post pivoted to one tongue and extending through the other tongue; and a lever pivoted to the post and arranged to draw the two tongues together, one of said tongues being perforated at the gripping point.

7. The combination in a toggle, of a body portion having inner and outer tongues; a post; and a clamping lever pivoted to the post and arranged to bear against the outer tongue in line with the gripping surface,

S. The combination in a toggle, of a body portion having inner and outer tongues; a post pivoted to the inner tongue and extending through the outer tongue, said post having an arm extending at an angle from its outside end; and a lever pivoted to the arm and arranged to bear upon the outer tongue beyond a line drawn through the two pivots so as to lock the lever in position.
