  • the operation of the random selection device 10 will now be described, particularly with reference to one of its intended purposes, i.e., assisting the caller in selecting appropriate numbers during the playing of Bingo".
  • Loading is accomplished by removing the cover 16 after which the playing pieces 47 are loaded on top of the wall 22 of the casing 12 and the top surface of the blade 36.
  • Each of the playing pieces 47 is provided with appropriate indicia including the numbers l, 2, 3, etc. and the letters B, I, N, G or O, or an appropriate coloring scheme, such nomenclature being well known in the art. As will be apparent from FIG.
  • the sloping wall 15 tends to cause the playing pieces 47 to move downwardly towards the center of the blade 36, a single playing piece 47' eventually being positioned directly above the lift portion 44 of the ram 42.
  • Suitable means such as a conventional latching mechanism, may be employed to tightly secure the cover 16 to the casing 12.
  • the actuating rod 48 is mounted for pivoting movement about a pin 50 appropriately secured to the chassis 32, as illustrated in FIGS. 2 and 6.
  • the counterclockwise movement of the top of the actuating rod 48 causes the lower portion of the rod 48 to Contact the lever 52 mounted for rotation about the pin 54.
  • a spring 56 normally urges the rod 52 clockwise, as illustrated in FIGS. 2 and 6, such that the electrically insulating element 57 is positioned directly in the path of the resilient, electrically conductive prong 58 which is formed as an integral part of the electrically conductive disc 59 which is mounted to the shaft 60 appropriately journalled within the chassis 32.
  • Appropriate electrical circuitry is employed to permit the batteries to energize the motor 34 when the electrically conductive prong 58 engages the electrically conductive plate 62.
  • Such wiring is well known in the prior art and consists generally of connecting the resilient electrical contact 64 to one of the batteries by wire 66.
  • the other of the batteries 30 is appropriately connected by a wire 68 to the electrical motor 34.
  • the motor 34 is electrically connected to the electrically conductive plate 62.
  • the batteries 30 are otherwise electrically connected to each other.
  • the circuit for energizing the motor 34 is closed as the prong 58 contacts the plate 62.
  • the circuit is opened as the prong 58 contacts the insulating means 57 thus raising the prong 58 from its normal contact with the plate 62.
  • the gear wheel 78 is mounted on the shaft 80 also appropriately journalled within the chassis 32; An elongated gear wheel 82 and an integrally formed raised gear wheel 84 are also mounted for rotation with the shaft 80, as illustrated in FIGS. 2 and 3. .Gear wheel 84 meshes with the continuous rack of teeth 40 formed on the underside of the mixing blade 36 thus causing same to continuously rotate, as illustrated generally in FIGS. 2 and 5.
  • gear wheels 86 and 88 are mounted for rotation about the shaft 90 appropriately journalled within the chassis 32. As illustrated in FIG. 7, whereas the gear wheel 88 is fixedly secured to shaft 90, the gear wheel 86 is loosely mounted about shaft 90. Importantly, the gear wheels 86 and 88 are provided with an uneven number of teeth even though both wheels engage the elongated gear wheel 82.
  • the gear wheel 88 is provided with tabs 92 normally fitting within the oppositely disposed openings 94 of the gear wheel 86.
  • the gear wheel 88 moves downwardly, the smaller gear wheel 96 formed as an integral part thereof moves downwardly engaging the larger gear wheel 98 simultaneously compressing the spring I00.
  • the gear wheel 98 is mounted to shaft 60 thus causing same to rotate counterclockwise.
  • the downward movement of the gear wheel 88 is, as previously explained, responsible for moving the shaft downwardly at which time it is freed from its normal position rigidly securing the larger gear wheel 102 also mounted on the shaft 60. That is, as illustrated in FIG. 3, the upper end of the shaft 90 normally extends through a slot (not shown) within the periphery of the larger gear .wheel I02 preventing the gear wheel 102 from moving. However, as the gear wheel 88 moves downwardly, the shaft 90 also moves downwardly disengaging the gear wheel 102. Thus, in the position illustrated in FIG. 4, the gear Wheel 102 and its companion gear wheel 104 rotate counterclockwise.
  • the companion gear wheel 104 is provided with a cut-out portion 106 such that in the position illustrated no contact is made with the reciprocably mounted ram 42.
  • the gear wheel 104 rotates, the threads thereof in the uncut portion eventually contact the threads 46 of the ram caus ing the ram 46 to move upwardly to the position illustrated in 517.
  • the continued rotation of the gear wheel 104 beyond that position illustrated in FIG. 512 results in the release of contact between the gear wheel 104 and the ram 42 thus permitting the ram 42 to immediately drop to its original position illustrated in FIG. 5a.
  • the ram 42 is permitted to sequentially reciprocate as the mixing blade 36 continuously rotates.
  • the playing pieces 47 tend to move downwardly, at least one piece 47' always being located directly above the lift portion 44 of the ram 42.
  • the selected playing piece 47' is raised upwardly through the opening 18 in the cover 16 at which time the user is free to pick up same.
  • the electrically conductive prong 58 continues its rotation about shaft 60 eventually hitting the insulating medium 57 at which time its circuit is opened and the device deactivated. To select another playing piece, the user again pulls backwardly on the rod 48.
  • the caller during a Bingd game may utilize the random selection device of the present invention as follows.
  • the blade 26 is caused to rotate mixing the playing pieces 47.
  • the ram 42 automatically selects the most centrally disposed playing piece 47' and moves same upwardly through the opening 18 in the top of the cover 16.
  • the caller picks up the selected playing piece 47' and announces the selection to the group of people playing Bingo.
  • random selection device of the present invention has utility other than in the playing of Bingo.
