UNITED STATE PATENT ()FFICE.

SAMUEL M. RICHARDSON, OF WOBURN, ASSIGNOR OF ONE-HALF HIS RIGHT TO ALBERT T. STAHL, OF BOSTON, MASSACHUSETTS.

IMPROVEMENT IN HEELS FOR BOOTS AND SHOES.

Specification forming part of Letters Patent No. 217,486, dated July 15, 1879 application filed 1 June 16, 1879.

for Letters Patent of the United States, filed September 2, 1878, to which reference may be had.

The present invention relates to the devices for retaining-in position the mechanism which automatically and intermittingly rotates the heel-tip, as described in the former application, and also to means employed to attach the heel to the sole of the lasted boot or shoe.

The metallic shell or main body of the heel,

of cast metal, is provided with suitable internal projections to sustain the rocking shaft which moves the pawl, and also the metallic plate which forms both a support for the sole and a cover to hold the rocking shaft in posi tion.

Within the heel and extended up ward above the plate are long slender vertical projections adapted to pass upward through holes in the sole, and then be bent over or clinched upon it, to thereby securely fasten the sole and heel together. These projections or prongs are shown asdivigled longitudinally to permit the different prongs to be bent or. clinched in different directions. Figure 1 shows, in top view, one of my improved heels ready to be attached to a sole; Fig. 2, a partial section thereof on the dotted line a: m, Fig. 1, a part of the shell being broken away, and the attached sole being indicated in dotted lines. Figs. 3'and 4 are side views and plan of a modification of the plate and holding-prongs.

The rotating tip at, having the ratchet Z) attached to its shaft 2, is actuated by the pawl a, pivoted to the rocking shaft or lever 11, the

said shaft being moved in one directionby a spring, 6, and in the opposite direction by the weight of the foot on an arm or projection, f, of the rocking shaft or lever d, all substantiallyas in my other application.

- The shell or main body g of the heel is provided with suitable bearings or supports it for the rocking shaft (7, having the arms (1 and f. The upper portions of said bearings, together with another projection, 2', form a support for the plate Z, which holds the said shaft d in its bearings. This plate I also forms a support for the sole of the boot or shoe, and is provided with suitable holes or notches m m to receive the posts or studs n, (shown in Figs. 1 and 2,) as provided with prongs or projections n, which are to extend upward above the plate and the shell g. These posts nl are provided with strengthening ribs or projections 11, n adapted to be upset or headed to hold the plate Z in place as shown at u Fig. 2.

The prongs a are forked forasufficient depth to permit them to be bent in different directions after passing through holes in the sole, to thereby hold the sole firmly on the heel, as shown in dotted lines.

The shell a, with its different bearings and projections, hereinbefore described, may be formed as one casting.

The weight of the foot is applied to the arm f by means of a flexible or hinged flap (shown in dotted lines in Fig. 2) attached at the forward end to the insole by the prongs or otherwise.

. The plate l is provided with a projection, Z, to support a pawl, 1 which prevents retrograde movement of the ratchet b. r

In the modification shown in Figs. 3 and 4 the plate is formed in two parts, struck up from sheet metal, (one part only being shown,) the prongs n in this modification forming a part of the said plate rather than a continua tion of the posts, as in Figs. 1 and 2.

The plate shown in Fig. 3 has a projection, P, to hold the pawl l Iclaim- 1. In a heel provided with an automaticab ly-rot-ated tip, a plate adapted to hold the internal mechanism of the heel in place, and

at the same time form a support for the sole of the shoe, substantially as described.

2. A metallic heel-shell, combined with divided prongs adapted to pass through holes in the sole and be bent down and clinched thereon, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

SAMUEL M. RICHARDSON.
