will be rendered plastic.
As the parts are compressed, the plastic pyroxyline will be forced through the per-
forated head and shank of the hook an I within the free spaces on opposite sides of
said head and shank.
Any surplusago of pyroxylin material will ovortlow in the gutter, b.
The dies when sufficiently cooled are separated and the bar stripped of the finished
hooks.
Having now particularly describal and ascertained the nature of my said inven-
tion and in whit manner the same is to be performed 1 declare that what I
claim is:
1. The mode of covering the perforated hends and shanks of shoo lacing hooks with
pyroxyline or other suitable material, consisting in compressing said leads and shanks
and pyroxyline together in heated dies, substantially as set forth
2. The inode of covering shoe lacing hooks with pyroxyline or other suitable material,
consisting in compressing said hooks und material between heated dies which are con-
formed to the shape of the hook, said material being placed within said dies in the
form of a pallet and cansed to fuse and flow around the hook during the compre-sing
action of the dies, substantially as set forth.
3. The mode of covering shoe lacing hook, with pyroxyling material, which
necessitates the provision of a pair of dies having complementary recesses which
jointly conform to the finished hook the placing of the pyrosyline material in the
form of a pellet within the recess of the lower die, the assembly of the hook in
proper position immediately above said pellet, and the heating and compressing of
the dies whereby said material is fused and caused to flow around the hook and firmly
united to the latter as substantially as shown.
4. The mode of covering the perforated heads and shank of shoe lacing hooks
with pyroxyline material, consisting in forcing said material through and around said
heals and shanks by dies which are conformed to the shape of the finished head and
shank substantially as set forth.
5. The mode of covering shoe lacing hooks with pyroxyline materials consisting
forcible compressing said hooks within a confine space against a plastic mass of said
material substantially as set forth.
6. The herein described means for covering the heads and shanks of shoe lacing
hooks, consisting of a lower die having a depression, an intermediate bar cut away
and concaved, whereby the combined contours of said depression, cut away and
concaved portions, conform to the shape of the finished hook head, and an upper
die having perforation to accommodate the eyelets of the hooks, substantially as set
forth.
7. The combination of the dies and intermediate bars eut away and conformed to
the shape of the finished hook head, substantially as set forth.
8. The combination of the lower die which contains the pyroxyline material, the
intermediate har to which the hooks are attached, and the upper die substantially as
shown and described.
9. The combination with the hook carrying þar of the dies living their matting
faces cui away to enclose said har, substantially as set forth.
10. The combination of the die, A, having depression, a, and surrounding gutters, b,
the dio, D, having perforation. e, the intermediate bar, B, having concavity, e, and
cut away edge, d, and the dowel pin extending from the die, A, through the dia, D,
and intermediate bar, substantially as set forth.
