A pulley system for enabling an object attached to a line to pass around a rotating pulley at least partially enclosed by a housing, without causing the object to encounter interference from the housing structure as the object passages through. An inward beveled edge of the housing structure may act to guide the line into the pulley groove. An object passthrough window for allowing the object to pass around the pulley while the pulley is rotating, without encumbrance of the object, may comprise a substantially solid, or continuous, inner surface formed of the inward beveled edge and the pulley groove. An exemplary use of the pulley system is in drive or transfer pulleys, or both, in systems utilizing pulley arrangements: for example, in systems such as lure coursing systems that continuously loop a line having a lure attached, for the enjoyment of domesticated animals.

Disclosure in this specification is of a greyhound lure support carrier engageable with a support track is located about a greyhound racing track. The support carrier is engageable and disengageable from the track in one example, the carrier housing supports multiple wheels some of which are in constant contact with the track to drive the carrier housing along the track and other wheels are free-wheeling guides along the track and to ensure the carrier housing stays on the track. The support carrier comprises a chassis accommodating, a battery to supply electric power; an electric motor having an axle, the electric motor operatively connected to the battery, and to drive the rotation of an axle; a rotatable friction arrangement connected to a driven axle and located so as to frictionally engage with the support track. There is a suspension arrangement moveable against a portion of the support track to permit suspension of the chassis from the support track. There is also a wireless communication receiver for receiving a signal for operating application of electric power to the electric motor. An electric motor control module is in operative connection to the wireless communication receiver and operable to the electric motor. A lure arrangement is attachable to the carrier for attracting greyhounds as the carrier is controlled in its travel about the track.

A lure coursing system for the enjoyment of domesticated animals comprising: a motorized drive unit disposed at a first location, the motorized drive unit including a drive housing enclosing a drive pulley operatively connected to a motor; a transfer unit disposed at a second location, the transfer pulley unit including a transfer housing enclosing a transfer pulley; a lure line engaging the drive pulley and the transfer pulley so as to form a continuous loop configuration for the lure line; and a lure attached to the lure line.

An aquatic race assembly system and method of conducting canine races, which includes two lanes, separated by a partition and a platform with a start line, a predetermined distance from one end of the platform. The platform is positioned proximate to a body of water or a pool. A sensor is placed in each lane, to automatically monitor the dog's position at the start and sending a signal to the control system, which determines whether there was a false start. When a dog bites and pools the lure places at a set distance on the other end of the pool, the lure is disconnected from the control system, causing a signal with the timing information to be sent and processed.
