Definitions

  • This invention relates to a lure device.
  • a lure device for use on a greyhound track.
  • Greyhound tracks are well known. They generally comprise a circular or oval shaped arena surrounded by a spectator area. In the arena, greyhounds are raced from respective traps, located at a start line, to a finish line a predetermined distance away around the track.
  • a lure is provided which, generally speaking, comprises a silhouette of a hare fixed fast to an endless cable.
  • the cable is usually buried in suitable casing underground with a slot in the casing for enabling a support connecting the lure to the cable to pass through the casing.
  • the lure is set in motion by means of a suitable motor housed in a control centre located at some suitable point on the track which drives the cable on the circuitous pathway around the perimeter of the track.
  • the velocity of the cable will determine the velocity of the lure and there is usually suitable means for varying the velocity of the cable depending on the velocity of the dogs chasing the lure.
  • the invention therefore provides a support apparatus for supporting a lure which apparatus comprises a trolley having wheels for engaging with one or more rails; a drive pulley and two associated idler pulleys; a drive means for the drive pulley; the arrangement being such that when mounted on the or each rail, the drive pulley and the associated idler pulleys are interengageable with an endless stationary cable so that upon actuation of the motor means the trolley moves along the rails relative to the stationary cable.
  • an apparatus 10 which comprises a trolley 50 having a support element 51, a motor (not shown) mounted in a housing 54, a first pair of wheels 55; a second pair of wheels 56, a drive pulley 57 and idler pulleys 58, 59.
  • the motor which is electrically powered, is mounted on the support element 51 by means of a pair of brackets 60, 61.
  • An electrical cable 62 is connected to the motor the free ends 63, 64 of which cable 62 are connected to a respective electrical brushes 65, 66.
  • Each brush 65, 66 is hingedly attached to a respective brush support member 52, 53.
  • the brush support member 52 comprises a housing 72 having a spring (not shown) which biases a plunger 73 outwardly from the housing there being conventional means (not shown) to retain the plunger 73 in the housing 72. Essentially, therefore, the plunger 73 is slidably engageable in the housing 72. The free end of the plunger 73 is pivotally attached to a lug 74 to which is fixed fast the brush 65. The brush 65 is electrically isolated from the lug 74. The housing 72 is pivotally attached to one end of a brush support member 75 the other end of which is attached to the plate 51.
  • the brush support 53 is similarly constructed and supports the brush 66.
  • axles 76 Also attached to the support element 51, by means of respective axles 76, are the pairs of wheels 55, 56 which are of the flanged type. Projecting from the motor is an axle 67 on which is mounted the drive pulley 57.
  • the support element 51 also has mounted thereon the idler pulleys 58, 59.
  • the axes of the pulleys 57, 58, 59 are in substantially parallel spaced apart relationship being transverse to the axes of the wheels 55, 56.
  • the location of the axes of the pulleys 57, 58, 59 are such as to form a notional triangle with a notional line joining the axes of the idler pulleys 58, 59 forming the base of the triangle and the axis of the drive pulley 57 forming the apex of the triangle.
  • the pulleys 58, 57 are substantially coplanar; the pulley 59 is slightly non-coplanar relative to the pulley 57.
  • first arm 68 Pivotally attached to the support plate 51 by means of a lug and pin arrangement 78 is first arm 68 from which projects a skid 69.
  • the arm 68 has one end of a spring 70 attached thereto the other end of which spring 70 is attached to a second arm 71 attached to the plate 51.
  • Further support for the arm 68 is provided by an L-shaped leg member 79 one end of which is welded to or is integral with the arm 68 the other end of which member 79 is pivotally attached to the plate 51 by a lug and pin arrangement 80.
  • a lure 77 Also attached to the arm 68 is a lure 77.
  • a series of main frame supports 11 At distances of approximately 2.5m from each other.
  • Each support 11 is substantially U-shaped having legs 12 and 15 interconnected by a connecting arm 14.
  • the leg 12 is longer than the leg 15 and thus the end of the leg 12 is embedded in a concrete base 13 located below the ground 13 a .
  • the end of the leg 15 is located a distance above the ground 13 a .
  • Mounted on the leg 15 are two nut and bolt arrangements 16 a , 17 a for supporting respective rails 16, 17.
  • the rails 16, 17 are in substantially parallel spaced apart and positioned one above the other.
  • an L-shaped bracket 19 having legs 20, 21.
  • the leg 21 supports an electrically insulating medium 25 having electrically conductive strips 22, 23 embedded therein, each strip 22, 23 having an exposed surface.
  • Mounted on the leg 15 and located between the rails 16, 17 is a cable support element 18.
  • the rails 16, 17, the L-shaped bracket 19, the support medium 25, the strips 22, 23 are all endless and circumscribe the outer perimeter of the greyhound track. If desired an endless facia 100 could be attached to the legs 15, so as to cover the rails etc. from the general view of the public.
  • the cable 24 which would be endless would simply rest on the supports 18.
  • the cable 24 would be of the type in which a length of 500 metres would have a weight of about 65kg.
  • the apparatus 10 is lifted into position so that the wheels 55 rests on the rail 16 and the wheels 56 rest on the rail 17.
  • the cable 24 is engaged with the drive pulley 57.
  • the pulleys 58, 57 are substantially coplanar but because the pulley 59 does not share the same plane as that of the pulleys 58, 57, that part of the cable 24 which connects the pulley 58 with the pulley 57 is not in friction engagement with that part of the cable 24 which connects the pulley 57 with the pulley 59.
  • the electric brushes 65, 66 are placed in electric contact with respective strips 22, 23.
  • the strips 22, 23 are, at some suitable location, connected to a source of electricity controlled by a switch and/or suitable current varying means so as to vary the current and/or voltage in the strips 22, 23.
  • the motor on the trolley 50 When electricity is applied to the strips 22, 23, the motor on the trolley 50 is actuated thereby causing the drive pulley 57 to rotate. Rotation of the drive pulley 57 causes the trolley 50 to move relative to the stationery cable 24 along the rails 16, 17 thereby causing the trolley to move around the greyhound track.
  • the idler pulleys 58, 59 served to guide the cable to and from the drive pulley.
  • the velocity of the trolley 50 may be controlled by varying the current or voltage applied to the strips 22, 23.
  • the purpose of the skid 69 is to prevent the lure 77 from being damaged through contact with any undulating ground.
  • the skid 69 is in contact with the ground and serves to push the arm 68 against the bias of the spring 70. It will be appreciated that the arm 68 projects beyond the plane of the facia and hence the lure 77 if located in front of the facia 100 will be easily silhouetted against the preferably plain background of the facia 100.
  • the advantages of the invention include the fact that when installed in a track having a sand base, little of no damage is caused to the apparatus 10 by the sand given the relatively simple construction thereof and the lack of movement of the cable 24.
