  • the gear 113 is engaged with the pinion 109.
  • One end of the sleeve 117 is projected from the frame member 102 and has a cam 119 with a recess 123 fixed thereon.
  • the sleeve 117 fixes a timer 118 which consists of a metal disc 118' and an insulating disc 120 with a smaller diameter than that of the metal disc 118', attached to the metal disc 118 and having a projection 120' on its periphery projecting from the periphery of the metal disc 118".
  • An electric contact plate 121 is fixed on the frame member 102 through an insulator 122 in such a manner that one end of the electric contact plate 121 is in contact with the periphery of the timer 118.
  • a pin 125 is fixed on the inner surface of a lever 124, and is engageable with the cam 119.
  • the lever 124 and the lever 112 are combined as one body by a cross member to form a U-slhaped member which is rotatably supported on the frame member 102 by means of a mounting hole 126.

  • a curved engaging hole 128 is formed in the upper portion of the lever 124, into which a pin 130' fits, as described below.
  • a rotary shaft 131 is fixed on an attachment 132 of a cup 130, which is rotatably supported at holes 131', 131' of triangular bearing members 102", 102" formed on the frame members 102 and 102'.
  • the pin 130' also is attached to the attachment 132 and is designed to be engaged with the curved engaging hole 128 for the shaking of the cup 130.

  • Another terminal of the dry cell 141 is connected to the metal disc 118 of the timer 118 and the electrode 140.
  • the electrodes 139 and 140 form a switching means for the starting of the motor 103.
  • the mounting disc 138 sinks somewhat so as to bring the electrode 139 fixed at the back side of the mounting disc 138 into contact with the electrode 140 fixed at the bottom of the cup 130. Consequently, since the dry cell 141 is connected to both tenninals of the motor 103, the motor 103 immediately starts to rotate.
  • the insulating projecting 120 of the timer 118 fixed on the sleeve 117 lifts up the corresponding electrode 121 so that the corresponding connection between both terminals of the motor 103 is broken there.
  • the metal disc 118' and the insulating disc 120 of the timer 118 start to rotate, and so the electrode 121 comes into contact with the metal disc 118. Consequently the motor 103 continues to rotate in the self-holding.
  • crank 110' of the crank shaft 110 which rotates at a higher speed than the timer 118, collides with the bend 112' of the lever 112 every revolution to rotate the lever 112 clockwise around the hole 126.

  • the crank 110' intermittently strikes the bend 112' to swing right and left the lever 112 as well as the lever 124 combined with the lever 112 as one body.
  • the pin 130 is slideably engaged with the curved engaging hole 128 of the lever 124, and therefore it is moved up and down along the curved engaging hole 128 with the left and right swinging motion of the lever 124.
  • the pin 130 swings left and right around the rotary shaft 131 and also the cup 130.
  • the cup 130 swings left and right, or is shaken left and right with the swing motion of the lever 124.
  • the pin 125 is released from the recess 123 after the die or dice has been cast out.
  • the timer 118 performs just one revolution, and the projection 120' lifts up the electrode 121 to break the electrical connection between the electrode 121 and the metal disc 118' of the timer 118.
  • the motor 103 stops to put the cup 130 into the stationary state.
  • a cup 202 is disposed at an upper position of a base member 201.
  • a rotary shaft 203 is disposed at a lower position and has a gear 204 fixed thereon.
  • the gear 204 is engaged with a rack 206 formed on an upper portion of a hook-shaped lever 205 pivoted at its lower portion on the base member 201.
  • a coil spring 208 is stretched between a part of the base member 201 and one end portion of the lever 205 to tension the lever 205 clockwise.
  • a sliding surface 205 with which a crank 209 of a crank shaft 225 is in contact, is formed on a recess portion of the lever 205, and a projection 205" with which a cam 210 is engageable, is formed on a center portion of the lever 205.
  • the cam 210 is fixed at one end of a main shaft 211, with which a disc 212 is combined as one body.
  • the disc 212 is provided with a curved bend 212'.

  • a motor 213 is arranged under the base member 201 as a drive source.
  • a rotary shaft 216 is driven by a pinion 214 fixed to the motor 213 and a gear 217 is engaged with the pinion 214 on which a pinion 215 is fixed.
  • the pinion 215 is engaged with a gear 218 supported rotatably on the main shaft 211.
  • a pinion 219 is combined with the gear 218 as one body.
  • the pinion 219 is engaged with a gear 222 fixed on a shaft 220 which is driven at a reduced speed.
  • a pinion 221 is fixed on the shaft 220 on which a coil spring 223 is stretched between one end of the pinion 221 and the frame member 201 in such a manner that the shaft 220 can move in the axial direction.
  • the shaft 220 is moved right hand against the coil spring 223 so that the pinion 224 fixed on the crank shaft 225 is released from the engagement with the gear 222.
  • the crank shaft 225 rotates only when the pinion 224 is engaged with the gear 222.
  • the main shaft 211 is driven by the motor 213 through the pinion 214, the gear 217, the pinion 215, the gear 218, the pinion 219, the gear 222, the pinion 221 and the gear 226.
  • a metal cylinder 227 is combined with the gear 226 as one body on the shaft 211, on which a timer 228 is fixed.
  • the timer 228 consists of a metal disc 229 electrically connected to the main shaft 211 and the frame member 201, and an insulating disc 230 with a somewhat smaller diameter than that of the metal disc 229, fixed on the metal disc 229.
  • a projection 230' is formed on the periphery of the insulating disc 230, projecting from the periphery of the metal disc 229.
  • An electrode 231 is disposed so as to be in contact with the periphery of the timer 228. When the electrode 231 is lifted up on the projection 230, the electrical connection between the metal disc 229 and the electrode 231 is broken.
  • FIG. 4 shows the driving circuit of the motor 213 including the electrode 231.
  • One terminal of the motor 213 is connected to one terminal of a dry cell 232 with another terminal of which is connected to the frame member 201.
  • Another terminal of the motor 213 is connected to a starting switch 236, 237 which is disposed in the cup 202.
  • a mounting disc 235 is supported by a supporting axis 234 and a coil spring 233 wound around the supporting axis 234 in such a manner that it can move in a vertical direction.
  • An electrode 236 is fixed on the back side of the mounting disc 235 and a stationary contact 237 is fixed on a bottom of the cup 202.
  • the stationary contact 237 is electrically connected to the rotary shaft 203 and then one terminal of the dry cell 232.
  • the electrode 236 is electrically connected to a metal ring 239 fixed on an insulating attachment of the cup 202 through a lead line 236.
  • a plate contact 240 is fixed at a part of the base member 201 through an insulating plate 241 so as to be in contact with the metal ring 239.
  • the plate contact 240 is electrically connected to one terminal of the motor 213.
  • the electrode 236 and the stationary contact 237 form the starting switch of the motor 213 which is closed when the die or dice are cast into the cup 202.
  • the timer 228 is connected with the starting switch 236, 237 in parallel to self-hold the driving of the motor 213 for a given period of time.
  • the mounting disc 235 When the die or dice are cast into the cup 202, the mounting disc 235 is moved downward by the weight of the die or dice to bring the electrode 236 fixed on the back side of the mounting disc 235 into contact with the stationary contact 237. Consequently the motor 213 is connected to the electric power source to start. Before the starting of the motor 213, the projection 230 of the timer 228 lifts up the electrode 231 so that the electric connection is broken there. The rotation of the motor 213 is transmitted to the main shaft 211 through the pinion 214, the gear 217, the pinion 215, the gear 218, the pinion 219, the gear 222, the pinion 221 and the gear 226 at a reduced speed.

  • the crank shaft 225 is driven by the engagement of the pinion 224 with the gear 222.
  • the crank 209 of the crank shaft 225 collides with the sliding surface 205 of the lever 205 every revolution. Since the lever 205 is pivoted at the pin 207, the lever 205 is rotated anticlockwise everytime the crank 209 collides with the sliding surface 205' of the lever 205. On the other hand, the lever 205 isclockwise tensioned by the spring 208, and therefore the lever 205 is shaken left and right with the rotation of the crank shaft 225.
  • the gear 204 engaged with the rack 206 formed on the upper portion of the lever 205 is rotated anti-clockwise and clockwise with the swing motion of the lever 205 around the pin 207. While the crank 209 is engaged with the sliding surface 205', the gear 204 is rotated clockwise. When the crank 209 is released from the sliding surface 205', the lever 205 is rapidly drawn back by the spring 208 so that the gear 204 is rotated anticlockwise. Thus, the cup 202 is shaken left and right, or is swung with the swing motion of the lever 205. On the other hand, the timer 228 fixed on the main shaft 211 is rotated at a lower speed than the crank shaft 225.
  • the cam 210 and the disc with the curved bend 212 fixed on the main shaft 211 are rotated at the same speed as the timer 228.
  • the cam 210 is rotated clockwise in FIG. 7 and meanwhile pushes up the projection 205" of the lever 205 from the downward position.
  • the gear 204 is rotated on a larger angle, over about 45, by the rack 206 formed on the upper end of the lever 205, whereby the cup 202 is tilted greatly clockwise or right hand in FIG. 7 to cast out the die or dice.
  • the projection 205" of the lever 205 is rapidly released from the cam 210 and the lever 205 is rapidly rotated clockwise by the spring 208 to put the cup 202 into the original stationary state.
  • the top end 220' of the shaft 220 in contact with the margin of the disc with the curved bend 212' rides up on the curved bend 212 with the rotation of the disc 212 to be pushed in a right hand direction in FIG. 8, so that the pinion 224 fixed on the crank shaft 225 is released from the engagement of the gear 222 to stop the rotation of the crank shaft 225.
  • the lever 205 is returned exactly to the original position by the spring 208.
  • the disc with the curved bend 212 moreover rotates to release the top end 220 from the engagement of the curved bend 212. Therefore, the pinion 224 again is engaged with the gear 222 by the function of the spring 223.
  • the timer 228 rotates exactly once so that the projection 230' lifts up the electrode 231 to stop the self-holding of the motor 213 and therefore stop the rotation of the motor 213.
