Abstract
Abstract An apparatus for exercising and training of animals with a movable floor formed by an endless belt which may be driven with any desired speed, and whereby to enable the floor to simulate as closely as possible, the elasticity and the like physical properties of the natural surface as f.inst. the turf, the upper portion of the belt is supported by and sliding on a smooth plate, and the endless belt is made of a flexible plastic material with a low coefficient of friction, which on the outward side is covered by a coir mat with long upright pile, and the supporting plate resting on rubber blocks.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
189 words
Apparatus for exercising and training horses comprising an elongated substantially horizontal framework, a pair of drums pivotally mounted at opposite ends of said framework, driving means for one of said drums, a flexible endless belt carried by said drums and forming upper and lower portions thereof between said drums, a smooth plate underlying and slidably supporting said upper belt portion between said drums, means carried by said frame for resiliently mounting said plate, and means for tensioning said belt including a tension roller, a hydraulic cylinder coupled to said tension roller, and a pair of horizontally spaced guide rollers carried by said frame, said guide rollers and said tension roller acting on said lower belt portion with at least one of said pair of guide rollers and said tension roller being located to elevationally offset said lower belt portion thereby to maintain said belt taut between said drums with a constant tension about said drums, said belt having an inner facing layer of flexible plastic material and an outer facing layer joined to said inner layer, said outer facing layer comprising a coir mat with a high upright pile.
Claim 2
Dependent Claim
189 words
Apparatus for exercising and training horses comprising an elongated substantially horizontal framework, a pair of drums pivotally mounted at opposite ends of said framework, driving means for one of said drums, a flexible endless belt carried by said drums and forming upper and lower portions thereof between said drums, a smooth plate underlying and slidably supporting said upper belt portion between said drums, means carried by said frame for resiliently mounting said plate, and means for tensioning said belt including a tension roller, a hydraulic cylinder coupled to said tension roller, and a pair of horizontally spaced guide rollers carried by said frame, said guide rollers and said tension roller acting on said lower belt portion with at least one of said pair of guide rollers and said tension roller being located to elevationally offset said lower belt portion thereby to maintain said belt taut between said drums with a constant tension about said drums, said belt having an inner facing layer of flexible plastic material and an outer facing layer joined to said inner layer, said outer facing layer comprising a coir mat with a high upright pile.
Claim 3
Dependent Claim
17 words
The apparatus of claim 1, wherein the pile height of the coir mat is about 1-1.5 inch.
Claim 4
Dependent Claim
29 words
The apparatus of claim 1, wherein the inward facing layer of the belt is made of polyuretan reinforced by nylon fibres arranged in a longitudinal direction of the belt.
Claim 5
Dependent Claim
27 words
The apparatus of claim 1, wherein the driving means for the belt comprises one or more hydraulic motors with means for continuously varying their speed of rotation.
Claim 6
Dependent Claim
103 words
Apparatus according to claim 1 wherein the pile height of the coir mat lies within a range of 1 to 1 1/2 inches, the inner facing layer of said belt being formed of polyurethan reinforced by nylon fibers extending longitudinally of the belt, said driving means including a hydraulic motor and having means for continuously varying the speed of rotation of the drums, a concrete block underlying said plate and supported on said frame by said resilient mounting means, said plate including a polished sheet of stainless steel supported by said concrete block along its supper surface and underlying said upper belt portion.
