low cup-shaped recesses 31 which are disposed in a'n are about the center of the wheel an equal distance apart like the contact plates. The angular distance between these recesses 31 is the same as the angulardistance between the contact plates, as will be readily understood. At its ends the main contact p ate 30 is provided with bevel edges 32, the pur ose of which will appear more fully herema ter. At its ends the contact plate is bent upwardly so as to resent stop wings 33, and these wings are a( apted to limit the movement of the wheel, as will be readily under stood. It should be noted that these wings lie substantially in the saine arc as therecesses 31.i As indicated most clearly in Fig. 4, on the inner face of the segment 13, a socket 34 is provided, which receives a coil spring 35, and this spring 35 thrusts outwardl against the inner end of a pin 36, so as to liold this pin projectin outwardl through a guide plate 37, in w 'ich the pm is slidabl mounted. The end of this pin 36 is rounde as shown, and is ada ted to be received in the recesses 31 so as to old the wheel in a fixed position. The bevel edges 32 referred to above, are substantially in alinement with the contact pins 26 so that if the roger side of the chain 18 is ulled, the wheell) wi l rotate so that the beve edge 32 will pass under the heads 27 of the pins in succession. 'lhe pin 36 will be forrcd into the recesses 31 in succession as this rotation continues, and will hold the wheel fixed position so that a circuit can be formed through one light, two lights, three lights, andso on. In the rst pos1tion the ,circuit will be formed through the lefthand light, as shown in Fig. 2, in the second position, through this light, and the one next to it, and so on. In this connection it should be understood that the contact plate 30 receives its current from the contact plate 19' through the medium of the pin 26* at the contact plate 19. As soon as the contact plate 30 comes in contact with the next pin, 1t throws the circuit through the first lamp. In this manner, if the contact plate 30 touches three of the contact ins in addition to the contact in 26, it w` close a circuit through three lghts, and so on. It will be noted that the circuit arrangement is'such that the lights are also arranged in parallel circuit. In order to steady the hanger in osition in the shell or case 1, the horizonte bar 11 of the ha er is connected with the lower section 3 t rough a tubular stem 38, to which the ornamental lower tip 39 of the electrolier is attached. ith a switch constructed as described, 1t will be 4evident that the wheel can be advanced by Va step-by-step movement, and 1n each successive posltion another light .will be thrown into the circuit. The stop wings 33 will strike the )in 36 so as to limit the mowment of the W reel whenl the lights are qll in circuit or all out of circuit. I Attention is called tothe fari that the heads 27 of the pins are rounded where they touch the side of the wheel, and this form facilitates their riding up on the inclined or bevel edges 32. Attentlon is also culled to the rounded form of the end ol' the pin 3G which fits into the 4recesses 3l. This form enables the pin 36 to be dislodged from the recesses by a sudden or forceful movement of the wheel. Having thus described my invention, I claim as new and desire to secure by Letters Patent,- 1.
