Abstract: 10,680. Jackson, W. J. Mellersh-, [Roever Patent Co.]. May 6. Multiple machines; driving, speed-regulating, etc.; trumpets, supporting; brushing records; cases and stands.-Relates to improvements in multiple phonographs where rotation of the wheel 37, Fig. 5, carrying the records 39 brings the records successively or selectively into position. Hand or coin-operated means release the motor B, Figs. 6 and 9, which is automatically stopped at the end of each reproduction by the agency of the reproducer carriage 99, Fig. 4, and a vertical lever 94, Figs. 5 and 9, pivoted at 95. The motor first causes the return of the reproducer - carriage to the commencement of the record; this disengages the selective handfeed 48, Figs. 5 and 10, and advances the recordwheel by a pawl 44, Fig. 10, finally locking it for the reproduction. The motor B may have handrelease means only, Fig. 8. On a drum 54 driven by the motor is a brake-strap 55 with projecting end. A detent 57 in the path of this end and mounted on a gravity arm 58 (see also Fig. 9) may be removed by a connecting- rod 61 aod crauk 02 on turning a finger-piece 65. Alternatively, hand or coin operated means may be combined, as shown m Fig. 6, where the rod 61 is connected to a bent lever 66 the end of which may be struck by a pin 74 on the finger-piece 75. In the coin-release, the slide 77 contacting with a slide 72 connected both with the bent lever 66 and with a lever 80, removes the hand-operated detent and momentarily tilts the end 87 of the lever 80 into the path of the brakestrap ; the lever 80 springs back on release of the slide 77. The detent 57 is held off during reproduction by a toe 92 on the vertical lever 94 which swings by gravity underneath an adjustable arm 88 on the gravity arm 58. A freely-swinging arm 106 prevents the machine from being started by tilting it. The motor by a belt 23 and one of the gears 111, 112, Fig. 4 (according to the length of the record), rotates the screw 115 and returns the reproducer to the starting position. The reproducer-carriage by a chain 129, Figs. 4 and 10, and cushioned connexion 137, raises an arm 135. This raises a link 150 and depresses the other end of a pivoted weighted lever 153 in which one end of a shaft 49 is journaled. This movement carries the friction-wheel 48 out of engagement with the record-wheel 37, Fig. 5, the wheel 48 constituting, when in use and rotated by hand-means, the selective feed of the record-wheel. As the arm 135 rises, the gravity-pawl 144 engages with one of the pins 145 on the record-wheel and thus brings the next record into position. The pawl then contacts with an arm 156 of a weighted lever, removing the end of the other arm 157 from the path of a spring-pressed pin 101 mounted on the vertical lever 94, and allowing the pin to lock the recordwheel. The record is rotated by a wheel 29, Figs. 4 and 5, on the shaft 25 driven by the belt 23, frictionally engaging disks 35 on the shafts carrying the records. During reproduction the arm 135 falls, the pawl being guided by the part 147 so as to be out of the way if it is desired to select a record. On the conclusion of a reproduction, the reproducer-carriage contacts with nuts 98 on a rod 97, Fig. 4, connected to the top of the vertical lever 94, withdrawing the locking-pin 101 from the record-wheel and pushing the toe 92 from under the arm 88 and thus applying the brake. The speed may be regulated by turning a screwed rod 124, Fig. 5, bearing on a spring-controlled bellcrank lever having a buffer to contact with a disk on the goveronr - shaft. A swinging brush is mounted on the shaft of the record-wheel to clean the records automatically. A pointer indicates the record that will be played on starting the machine. The machine is enclosed in a case having two compartments with doors, the lower compartment containing records. To allow of oscillation of the vertically arranged horn shown in plan in Fig. 14, it is pivoted near its mouth to the ends 17 of a fork 16 the base of which is pivoted in a bracket 18.
