Abstract: A split transport wheel is described including first and second wheel halves, each having an arcuate external tire receiving surface spanned by a joint surface. The two halves may be selectively assembled with the joint surfaces in juxtaposition and with the tire receiving surfaces forming a relatively continuous tire receiving surface. A clamp assembly releasably joins the first and second wheel halves and is selectively operable to (a) draw the respective joint surfaces together in juxtaposition and (b) release the first and second wheel halves to be separated. A tire, formed of a strip of tire material, may be releasably wrapped about the tire receiving surfaces of the wheel halves. A first tire end anchor on the first wheel half releasably receives one of the strip ends, and a second tire end anchor on the second wheel half releasably receives the remaining tire strip end.

Abstract: An animal exercising device adapted to be mounted overhead within a support structure spanning a prescribed floor or ground area. The device includes a drive sheave and a plurality of idler sheaves that are suspended overhead to receive an endless elongated belt. The drive sheave is operated by a motor to move the belt about a continuous cycle. A tether assembly is connected to the belt and includes a drum and retractable cord adapted to be connected to an animal's leash or halter. When the device is in operation the animal is led about the circuit defined by the driving and idler sheaves. When not in use the cord automatically retracts upwardly to provide a clear open area below the device that may be utilized for other purposes.
