IVI ETHOD OF ATTACHINC? WEAR-POINTS TO RUBBER BOOTS.
SPECIFICATION forming part of Letters Patent NO. 354,495, dated December 14, 1886.
Application tiled June 25, 1886. Serial No. 206,202. (No model.)
To @ZZ wiz/om, t may concern.-
Be it known that I, JUDSON L. THOMSON, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Methods of Attaching Tear-Points to Rubber Boots and Shoes, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.
This invention is designed as a further improvement in the process of applying metallic wear-points to the soles and heels of rubber boots and shoes described inmy Patent No. 335,323, of February 2, 1886. By the process therein set forth the metallic wear-points are secured to the primary rubber sole and heel, which are cemented to the usual inner cloth lining of the boot or shoe. The consequence is that the clinched ends of the prongs of the rivets or wear-plates are in too close proximity to the foot of the wearer, and the thin cloth lining over the said ends of the wearplates is rapidly worn away.
The object of my present invention is to preserve the inside lining of the boot or shoe, and to interpose a rubber sole and heel between the clinchedends of the rivets or Wearplates and. the foot of the wearer, so as to more effectually protect the latter, and to perfectly unite with said sole and heel the supplemental sole and heel which carry the rivets or wearplates; and to that end my invention consists i in the improved method of applying the metallic wearpoints, as hereinafter fully described, and specifically Set forth in the claim.
The annexed drawings illustrate my'invention in its various stages.
Figure l is a side view of a complete rub-- ber shoe embodying my invention. Fig. 2 is a vertical longitudinal section of the bottom of said shoe. Figure 3 is an inverted plan view of the Shoe, and Fig. 4 is an inverted plan view of the tap or the supplemental sole equipped with the metallic wear-points preparatory to attaching the said tap to the sole of the shoe.
My improved process of applying the metallic wear-points to rubber'boots or shoes is carried on during the manufacture of thelatter.
I form the boot or Shoe with the usual unvulcanized rubber bottom, a., or sole and heel in one piece in the ordinary and well-known manner; but before vulcanizing said boot or shoe I form taps or a separate supplemental sole, b, and heel c of unvulcanized rubber, generally by stamping or cutting said taps out of a sheet or sheets of said material. To these taps I secure the metallic rivets or wear-points d d by forcing the shanks or attaching-prongs thereof through the taps from the under side of the latter and clinching them on the upper side of the same, and in order to obtain a more secure hold for the clinches I cement onto the upper side of the tap a lining, e, of canvas or other suitable material and pass the attachingprongs of the metallicwear-points d d through said lining and clinch them upon the same, as illustrated in Fig. 2 of the drawings. This unvulcanized tap or supplemental sole b and heel @,with the metallic wearpoints attached thereto, as aforesaid, I cement at its `lined side onto the ordinary or primary unvulcanized rubber bottom or sole and heel ct, as shown in Fig. 2 of the drawings. After this is effected I vulcanize the boot` or shoe in the usual and well-known manner, and thereby effeetually unite the supplemental sole b and heel c with the ordinary or primary sole and heel a, and produce a rubber boot or shoe, which has the attaching Shanks or prongs of the metallic wear-points so embedded in its bottom as to securely retain them and effectually guard against penetration of water through the bottom.
I am aware that prior to my present invention rivets or wear-points have been applied to taps formed of vulcanized rubber, and such taps have been cemented to the vulcanized rubber sole and heel; but such construction is defective in that the vulcanized tap is liable to be cracked by the pressure received from the attachingshanks ofthe wear-points when forcing the same through the tap, and it is a Well-known fact that vulcanized-rubber surfaces cannot be securely cemented together; hence such prior construction fails to produce a rubber boot or shoe possessing theadvantages attained by my improved process of applying the metallic wear-points. Neither do I claim7 broadly, the attachment of metallic wear-points to the soles and heels of rubber' boots and shoes before the vulcanization of ihe same, as I am aware the same is not new 5 What I claim as new, andrdesire to secure by Letters Patent, is
The method of applying metallic wear-points tothe soles and heels of rubber boots and shoes,"consisting in forming the boot or shoe with an unvulcanized rubber bottom and forming a separate supplemental sole or heel of unvulcanized rubber, then cementing onto the upper side of the latter a lining of canvas or other suitable material, then forcing the attachingprongs of thc metallic wear-points through the said supplemental sole and heel and through the lining thereof, and clinching
