Abstract: 15,061. Lyon, E. A. July 2. Advertising.- Advertisements on a band wound from one roller to another and back are operated electro-magnetically by the receiver of a telephone. The band 9 is attached to rollers 7, 8 by means of wires held in grooves 10, Fig. 4. The rollers carry ratchet-wheels 13, 14, Fig. 3, which are engaged by pawls 18 carried by pivoted levers 15, 16, which are operated in turn by the rising or sinking of a polarized armature 26, thus working the band in either direction; one of two pins 20<1>, 21 holds one pawl out of engagement while the other is operative. The band 9 passes under a metal contact-sheet 35, and contains slots 41 separated by parts 42, so that spring- pressed rollers 39, 40 are periodically insulated from and brought into electric contact with the sheet 35. A pin 44 on the end of the armature 26 engages loosely a forked pivoted contactpiece 43 and moves it into or out of contact with a fixed contact 46, to render the motion of the apparatus intermittent. The rollers 7, 8 each contain a spring-pressed pivoted pawl 86, Fig. 8, having a projection 87 and a tooth 89<a>. When the band becomes wholly unwound from one roller, the part 87 is urged outwards, and the tooth 89<a> then engages a lever 85 carrying a pawl 84, which rotates a switch 49 by means of a ratchet-wheel 83, thus reversing the motion of the band. At the same time, levers 95, on being moved out of notches in the switch 49, act through pieces 93 on shafts 92 to put one detent 91 into engagement with its ratchet and withdraw the other. The switch 49 comprises metal bars 50, 51 running longitudinally, and plugs 52, 53, 54, 55 in contact with inner rings 56, 57, 58,59, Figs. 9 and 10. When the telephone receiver is removed from its hook, a bar 71 is pressed upwards by a spring to make contact with a piece 75, Fig. 11. Current from a battery 70 then passes by way of a spring 64, plugs 52, spring 60, roller 39, plate 35, wire 77, and contact 46 to a contact - breaker 43, from which part traverses the coils 30, 31 of an electromagnet, and part flows through a spring 62, plugs 54, and a spring 66 to the coil 34 of the pivoted armature 26, returning to the battery through springs 63, 67. The armature 26 is thus moved to the left and operates the roller 7 through the pawl lever 15 until the part 42 of the band 9 comes between the roller 39 and the plate 35, thus breaking the circuit. When the telephone receiver is replaced on its hook, the bar 71 makes contact with a piece 76, when the current passes by a spring 61, plugs 53, spring 65, roller 40, and plate 35 through the coils 30, 31, 34, and back as before, again moving the roller 7. By depressing a push-button 81, the current reaches the contactbreaker 43 by way of wires 82, 79, instead of by one of the rollers 39, 40, so that all the advertisements may be exhibited without using the telephone. When the band 9 is to be reversed, the rotation of the switch 49 causes the springs 60 ... 67 to be connected by the bars 50, 51 as shown in Fig. 12, and the armature 26 is moved to the right at each actuation, thus operating the roller 8. The current flows when the receiver is removed, by the path 75, 64, 50, 65, 40, 35, 46, and coils 30, 31 to the battery, while the armature coil 34 receives a reverse current by the path 74, 62, 51, 63, and thence back to the battery. When the receiver is replaced, the current flows by the path 76, 61, 50. 60, 39, 35, 46, and thence as before. A lamp 100 is connected with the battery to illuminate the band 9.
