To prevent the formoving dies which act on the side and rear mation of this objectionable projection on the 5 portions of the heel. The follower is usually upper edge of the breast of the heel during of the same size and outline as the seat of the the compressing operation, I have devised a finished heel and at its breast end is provided follower or mold that is provided with aheel- 7 5 with a lip for forming a bevel in the breast seat-engaging face and a connected breastend of the seat of the heel, such a bevel being plate, the acting face of the breastplate and 3 formed in the heel so that when it is being the heel-seat-engaging face being connected attached to a shoe the portion-of the heel that by a curved surface which will round off the is to be removed by the breasting operation upper edge of the breast of the heel or that will not cut into the shank portion of the sole edge formed by the junction of the seat and of the shoe and make an indentation which breast, and as one continuous surface is thus will be visible after the heel has been breasted. provided for acting upon both the seat and The breastplate, pressure-plate, and radiallythe breast of the heel there is no possibility moving dies in heel-compressing machines in of a roughened projection forming at the 5 general use are mounted on a cross-head, said junction of these two faces.

Fig. 2 is an enlarged sectween them into which some of the leather of tion of the compressing-dies of said machine, the heel will flow and form a roughened proand shows a heel-blank in position to be operated upon. Fig. 3 is a perspective view showing the follower or mold in an inverted position. Fig. 4: is a perspective view of the buffer-plate provided. with a guideway to receive the breastplate depending from the follower. Fig. 5 is a perspective view, partly in section, of a heel on which a roughened projection was formed during the compressing operation; and Fig. 6 is a perspective view, partly in section, of a heel that has been compressed in a machine provided with my improved follower.

My invention is shown in Fig. 1 as applied to a heel-compressing machine, such as is now in general use. As such machine forms no part of my invention, however, it is not de scribed; but it should be understood that the application of my invention is not limited to any particular type of heel-compressing Inachine.

In the preferred form of my invention, as shown in Fig. 3 of the drawings, the follower or mold 2 has a heel-seat-engaging face 8 for molding the seat-face of the heel, said follower being provided with a connected breastplate 4 for acting upon the breast of the heel and also provided with a lip 12 for forming a bevel in the breast end of the seat of the heel. The said lip constitutes a portion of the heelseat-engaging face and has an acting face which is connected with the acting face of the breastplate by a curved surface 7, that is adapted to engage and round off the upper edge of the breast of the heel or that edge formed by the junction of the breast 6 and the beveled portion 11 of the seat 10, as shown in Fig. 6.

In Fig. 5 is shown a portion of aheel that has been compressed in dies such as heretofore have been ordinarily used. the roughened projection formed thereon during the compressing operation being designated by the character l l. It can be readily seen that such a roughened projection or even a sharp edge could not be formed on a heel compressed by my improved follower or mold, because the portion of the follower that acts on the upper edge of the breast is curved, as shown at 7 in Figs. 2 and 3. As said curved surface forms a connection between the heel-seat-engaging face and the acting face of the breastplate, these two faces are merged into one continuous surface, which molds the seat-face of the heel, forms a bevel in the breast end of the seat, acts on the breast, and rounds off the upper edge of the breast at its junction with the beveled portion of the seat. Preferably the curved surface on the mold merges into the acting face of the breastplate, so that the mold forms on the upper edge of the breast of the heel a curved surface which merges into the face of the breast of the heel.

Preferably I provide means for reinforcing the breastplate to prevent too great strain on the breastplate during the compressing operation, which might result in frequent breakage of the breastplate-or at least in frequent displacement of the mold. In the machine to which I have shown my present invention applied I have employed for this purpose a buffer-plate 18, mounted on the cross-head 22, which carries the pressure-plate 24. and the ra-' dially-moving dies 26, said buffer-plate being provided with a guideway 20 to receive the breastplate 4 when the dies are in their closed position.

While in illustrating the preferred form of my invention I have shown the breastplate as formed integral with the heel-seat die, and while I believe that I am the first so to form a heel-compressing mold and desire to claim the same broadly, nevertheless my invention, so far as it relates to means for rounding the upper edge of the breast of the heel, is of course not limited to such a construction.

Having described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is j l. A follower or mold for compressing heels, provided with a heel-seat-engaging face, a heel breast engaging face, and a lip for forming a bevel in the breast end of the seat of a heel.

2. A follower or mold for compressing heels, provided with a heel-seat-engaging face, a heel-breast-engaging face, and a curved surface connecting said faces for rounding off the upper edge of the breast of a heel.

3. A follower or mold provided with'a heelseat-engaging face, a lip for forming a bevel in the breast end of the seat of a heel, and a connected breastplate, the acting face of the lip being curved downwardly and merging into the acting face of the breastplate.

4. A follower or mold provided with an engaging face and a lip for molding the seat-face of a heel, and a breastplate for acting upon the entire breast-face of the heel, said mold. also having a curved portion to round off the upper edge of the breast of the heel.

5. A follower or mold for compressing heels, provided with a heel-seat-engaging face, and a breastplate formed integral therewith for acting upon the entire breast of the heel.

6. A follower or mold provided with a heelseat-engaging face, a breastplate formed integral therewith for acting upon the breast of the heel, and a curved surface for rounding off the upper edge of the breast of the heel.

7 A follower or mold provided with an engaging face and a lip for molding the seat-face of a heel, and a breastplate formed integral therewith for acting upon the entire breastface of the heel, said mold also having a curved portion for rounding ofi the upper edge of the breast of a heel.

8. In dies for compressing heels, a follower or mold provided with a connected breastbreast-engaging face.

11. A follower or mold comprising a heelseat-engaging face, a face for acting upon the breast of a heel, and a lip for forminga bevel in the breast end of the seat of the heel, said lip being formed with a curved surface which merges into the face for acting upon the breast of the heel.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. I
