Abstract: 18,637. Gomber, G. W. Oct. 18. Phonographic apparatus.-The apparatus comprises a number of recording-cylinders, any one of which may be selected for recording or reproducing sounds by placing a coin in the slot and pushing in one of a set of buttons. The coin passes between the adjustable finger 120, Fig. 26, and one side of the weighted loop 116. If the coin is too small, it passes down the shoot 113 ; but, if the proper coin is used, the loop tilts on its pivot 117, and discharges the coin down the shoot 114. The coin then strikes the detent 121, and allows the T-shaped piece 101, weighted at 103, to turn on its pivot at 102 and raise the rod 107. The coin then falls on the lug 109, from which it is transferred to the lug 10, when the T-shaped piece is restored to its original position. The coin thus remains in view till the next proper coin is inserted. The rod 107 is connected to the lever 137, Fig. 25, which presses down the brake or other lever 136 controlling the electric or other motor. The lever 136 cannot descend until one of the levers 74 has been operated. These levers act on the arm 131 of a rock-shaft 128, the other arm 132 of which lies beneath the motor-actuating lever 136. The levers 74 carry operating-buttons, opposite each of which may be written the name of the song &c. recorded on one of the cylinders. The particular lever 74 selected is locked by a cranked bar 92, 93, 94, which can be pulled up by the spring 98 into the position shown only when the piece 97 is raised. This piece is fixed to the T-shaped piece 101, Fig. 26, near the rod 107. The records are adjustably mounted upon a wheel 20, Fig. 2, on a shaft 21, and the particular record chosen is brought beneath the reproducer 150 by rotating the wheel 20 by the pinion 41 and by stopping the wheel 20 by means of pins 73, the heads of which fit loosely in the levers 74 as shown. The pins 73 fit into a series of slots formed out of line with one another fixed to the wheel 20, there being a special slot for each individual pin. Projections may be used instead of slots. After the pin has engaged its slot, it is carried down a slight distance by the wheel 20, thus depressing a bar 72 fixed to the rock-shaft 69, Fig. 6. An arm 68 on this shaft thus moves the tail 66 fixed to the parts 51, 50, 12, 17, and 18, which all rock on the bar 6 and travel horizontally together. The part 51 carries a piece 55 acting on a bail 58 fixed to the rock-shaft 60. Thus, when the tail 66 is moved, the rock-shaft 60 is turned so that an arm upon it ceases to support the lever 43. This lever in falling disconnects the gears 45, 46, of which the gear 45 is on the same shaft as the wheel 41, Fig. 2, above mentioned. The magazine is thus stopped, and at the same time the half-nut 13, loosely mounted upon the part 12 above mentioned, is dropped upon the feeding-screw 16. The reproducer rigidly connected to the block 17 at the same time descends upon the record. The spindle of each record carries a spur-wheel gearing with a wheel on the shaft 30 of the driving-pulley 34. At the end of its travel the pin 53 strikes a spring 64, Fig. 2, and allows a spring to rock the shaft 60 and bail 58 back to their original positions. The arm 18, Fig. 6, also strikes against the weight 103, Fig. 26, of the piece 101, rocks it so that the detent 121 is re-engaged, stops the motor by means of the rod 107, and presses down the rod 95, Fig. 25, to allow the crank arm 92 to release the lever 74. A spring returns the reproducer with its connected parts back to their original position. The sound is conveyed through the pipe 153, Fig. 11, and is directed by a three-way cock 178 either to the horn 182 or to the ear tubes 183. The cock is worked automatically by the arms 192 for supporting the ear tubes. The arms are fixed to a rock-shaft 197 connected by arms 196 and 193 to the cock. On removing the ear tubes, the arms 192 are pulled up by a spring, and the sound is deflected from the horn to the tubes.
