Abstract: 28,596. Spear, E. H. Jan. 3, [date applied for under Patents Act, A.D. 1901]. Turnstiles; cha ngegiving apparatus. - Relates to automatic or coinfreed turnstiles adapted to separate cash received in payment of one or more admissions, to eject the change, and to control the number of admissions paid for or inserted in the machine. The locking - mechanism of the turnstile is operated electrically, and the locking and controlling of the cash-controlling and other devices are effected by the diameters of the coins inserted. Fig. 1 shows a turnstile adapted for single admissions, Fig. 5 shows the locking and releasing mechanism for the turnstile, Fig. 8 shows the coin receiving and separating mechanism, and Fig. 14 shows the change-ejectors and the means for operating them. The shaft 1 carrying the radial arms 3 has an ordinary ratchetwheel attached, and also the locking-disc 7, Fig. 5, and a square disc engaged by a pivoted throwing-arm to ensure that the turnstile makes a complete movement. To gain admission, a person inserts a coin in the slot 88 and depresses the button 87. The coin passing into the upper shoot 35, Fig. 8, is arrested by the offset 55 of the holding-lever 53. The slide 44 is moved and the trip lever 42 moving therewith causes the stud 50 to engage the lever 53, to rock the lever and withdraw the offset 55, permitting the coin to pass down the shoot 35. The holding-arm 56 is also carried forward and the offsets moved into the slots 40 to arrest the coin so that it can be engaged by the feeling or controlling finger 91 which regulates the operation of the change-making mechanism. The lever 42 is held in its forward position by the rack-bar 61. As the coin passes down the shoot 35, it closes the electric circuit, Fig. 5, whereby the arm 74 is withdrawn from the latch 70 and the latch frees the turnstile. When the coin passes into a lower shoot, the electric circuit being broken, the turnstile is locked. When the coin-receiving and separating mechanism is again operated, the coin is discharged from the lower shoot into its proper tube or receptacle. The rocking- frame 99 is raised by the operation of the turnstile. The diameter of the coin controls the height of the transverse member 122, so that, when that member is moved forward by the arms 101 of the frame 99, Fig. 14, the member engages certain pins 136, 137, 138, 139 and causes their ejectors to move forward and discharge the change. A suitable registering - mechanism is actuated from the rock - shaft 98. The coin receiving and delivery mechanism is provided with suitable mechanism for weighing and detecting spurious coins, which are rejected. In the modified apparatus shown in Fig. 16 adapted for admitting two or more persons and ejecting the necessary change between the cost of those admissions and the coin tendered, a pawl 162, Fig. 26, serves to control the movement of the turnstile, and the admission-controlling blocks 178, 179, 180, 181, 182 control the movement in one direction of the pawl 162 and regulate the ejectors in the change mechanism. The controlling-blocks are returned to their inoperative or elevated position by the eccentrics 170 rocking the trip-arms 171 and raising the yoke 185. The regulating bars 191, 192, 193, 194 are loosely mounted on the shaft 195 and their forward ends are bent and forked. The lowering arms 205, 206, 207, 208, 209 are of hook-form. The normal position of the pawl 162 is that in which its lug engages the spiral of the worm-shaft, 168 at one end and rests upon the guide-bar 158. The pawl is put out of engagement with the spiral by a tilting plate. The pawl 162 and guide-bar 158 are returned to their normal positions by the rotation of the worm 168. The push-rods effect the lowering of the controlling-blocks, and the pushbuttons are arranged for one to five admissions. The trip-lever 42 is connected to; the push-rods by the slotted bars 240. The change-ejecting mechanism for the modified turnstile is different from the simpler mechanism in the portion comprising the ejectors for the nickels and dimes. A locking - mechanism consisting of the two bars 278, 279 operated by the finger 280 ensures that only the number of admissions paid for are passed by the turnstile even if a wrong push-button is depressed.
