ments in Anvils for Hook-Setting Machines, of which the following is a specification.

This invention relates to an improvement in anvils for hook setting machines, and has for its'object to provide an anvil having mechanical means for retaining the hook in place on the anvil. I accomplish this ob-- ject by the mechanism illustrated in the accomp anying drawing, in which- Figure 1 is a perspective view of aspring for engaging the hook. Fig. 2 shows a top and an end view of a modified form of spring. Fig. 3 is a longitudinal sectional elevation of the anvil showing the spring in place. Fig. 4 is a top view of Fig. 3. Fig. 5 is an end view of Fig. 3.

Similar reference characters indicate similar parts in each view.

In the drawing, 9 represents an anvil used in setting shoe hooks, in which there is formed a longitudinal aperture 8. The upper'portion 7 of the anvil is recessed ateach end, at 12, in which the hooks are placed for setting.

In the lower face of the portion 7, of the anvil, is formed a longitudinal groove 10, to receive the spring 1. ilhe median ortion of the sprlng 1s flat and is provided with.an aperture 3 to receive the rivet 5, by means of which it is secured in a central aperture in the portion 7 of the anvil. The spring has a downward curve 2 near I each outer end, the extremities risin within the groove 10 to a height which Wlll permit the hook 6 to clear the end and pass over the curve 2, when being placed in position on the anvil. When the hook is forced into place the spring will be pressed up into the groove 10 and as the hook is forced home the curve 2 will return into the curved upper portion or cap of the hook, with sufficient force to serve its top of the hook and thereby retains it in position under all ordinary conditions. In this manner the hook will be made to stand in position when being set without the need of being held by the hand of the operator.

A modified form of spring is shown in Fig. 2 in which the central portion is enlarged at 1, to add strength in that portion where the spring is engaged with the anvil. The neck 4 adjacent the central base maybe reduced to the desired strength so that it will yield readily and yet will have urpose. The extremities are made in the s ape of a segment of a sphere, as shown at 2", so that they will fit the similarly formed cap of the hook.

In the base of the anvil is provided a vertical aperture 11, through which the rivet 5 is inserted and by means of which the spring is secured in the anvil.

Having described my invention so that others skilled in the art to which it pertains may make and use the same, what I claim as new and desire to secure by Letters Patent, is

1. A device for setting shoe hooks, comprising an anvil having therein a longitudinal aperture, and a spring secured by an intermediate point upon the lower face of the upper portion, each end of said spring being adapted to be engaged by the cap of I a hook, when seated in position on the anvil.

2. A device for setting shoe hooks, comprising an anvil, and a spring'secured by an intermediate point thereon, the free ends of the sprin beingadapted to be embraced by the cap 0 a hook when it is seated in position on the anvil,,for retaining the hook thereon. v

3. In a device of the character described, an anvil provided with a longitudinal aperture and a longitudinal groove in'the lower face of the upper portion, and a spring secured by an intermediate point to the lower face of said upper ortiqn, the ends of the spring being bowed downwardly and terminatmg in said groove.

4. In a device of the character described, an anvil provided with a longitudinal aperture and a longitudinal groove in the lower face of the upper portion, a spring secui'ed In testimony whereof I aflix my signature by an intermediate point to the lowt er face in presence of two Witnesses. of said upper portion the ends'o which are made to conform to the cap of a hock PIUS BAMMER' by which they are adapted to be engaged, Witnesses:
