Abstract
Abstract Shoes for horses are fabricated from ultra-high molecular weight ethylene polymers having a molecular weight of at least 1 million. Such shoes are light weight, have good wear properties, and are much easier on the horse's feet than metal shoes.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
21 words
A working horseshoe fabricated from an ultra-high molecular weight ethylene polymer having a molecular weight of at least about 1 million.
Claim 2
Dependent Claim
21 words
A working horseshoe fabricated from an ultra-high molecular weight ethylene polymer having a molecular weight of at least about 1 million.
Claim 3
Dependent Claim
22 words
A working horseshoe of claim 1 in which the ultra-high molecular weight ethylene polymer has a molecular weight of about 1-6 million.
Claim 4
Dependent Claim
11 words
A working horseshoe of claim 2 bearing an indicia of ownership.
Claim 5
Dependent Claim
79 words
A method for preparing a working horseshoe of claim 1 which consists essentially of filling a female horseshoe mold with a fine powder of an ultra-high molecular weight ethylene polymer having a molecular weight of at least 1 million, inserting a complementary male mold into said female mold, applying pressure on said male mold to compress the resin in said female mold, heating said mold to fuse said resin particles, and thereafter cooling said mold while maintaining pressure thereon.
Claim 6
Dependent Claim
11 words
A working horseshoe of claim 1 bearing an indicia of ownership.
Claim 7
Dependent Claim
45 words
A laminated working horseshoe comprising a first lamina fabricated from an ultra-high molecular weight ethylene polymer having a molecular weight of at least 1 million for direct attachment to a horse's foot, and a second lamina fabricated from metal for contact with a walking surface.
Claim 8
Dependent Claim
45 words
A laminated working horseshoe comprising a first lamina fabricated from an ultra-high molecular weight ethylene polymer having a molecular weight of at least 1 million for direct attachment to a horse's foot, and a second lamina fabricated from metal for contact with a walking surface.
Claim 9
Dependent Claim
22 words
A working horseshoe of claim 6 in which the ultra-high molecular weight ethylene polymer has a molecular weight of about 1-6 million.
Claim 10
Dependent Claim
53 words
A pad for protecting the foot of a horse and adapted to be applied directly to the horse's hoof and intermediate of the hoof and any working horseshoe carried on said hoof, said pad being fabricated from an ultra-high molecular weight ethylene polymer having a molecular weight of at least about 1 million.
Claim 11
Dependent Claim
53 words
A pad for protecting the foot of a horse and adapted to be applied directly to the horse's hoof and intermediate of the hoof and any working horseshoe carried on said hoof, said pad being fabricated from an ultra-high molecular weight ethylene polymer having a molecular weight of at least about 1 million.
Claim 12
Dependent Claim
49 words
A process for protecting the foot of a horse which comprises applying directly to the horse's foot a pad said pad being fabricated from an ultra-high molecular weight ethylene polymer having a molecular weight of at least about 1 million, and then applying a working horseshoe to said hoof.
Claim 13
Dependent Claim
49 words
A process for protecting the foot of a horse which comprises applying directly to the horse's foot a pad said pad being fabricated from an ultra-high molecular weight ethylene polymer having a molecular weight of at least about 1 million, and then applying a working horseshoe to said hoof.
