Abstract: 6296. Bender, W. H. March 15. Advertising.-Advertising or other matter is arranged upon curtains carried by spring rollers arranged in two groups, one at each end of a frame. A frame, which travels to and fro between the groups, carries clutches which successively replace and take a roller from each group, and exhibit the matter on its curtain. The frame comprises upper and lower plates 20, 21, connected together by uprights 22, 23 having cross-bars 25, 26. Mounted in these cross-bars are shafts 27, 59 which support roller carriers. The halves of the upper carrier are similar to the opposite halves of the lower carrier. The upper carrier comprises slotted discs 28, 29 rigidly connected by rods 30. The axles 33 of the spring rollers 34 are mounted in the slots 32 as shown in Fig. 9. At one end, the axles are flattened, and the slots are narrower, so that the axles cannot turn in them. The ends of the curtains are hooked or otherwise secured to the rods 30. The curtains may be secured to the rollers by inserting tongues 47, Fig. 12, into slots 48 in the rollers. In the form shown in Fig. 12, the rollers are connected by spiral springs 39 to their axles, and are secured by screws to hubs 40 mounted between discs 42 on the axles. To prevent the springs from unwinding when the rollers are not in their carriers, catches 44, adapted to engage the discs 42, are mounted in the hubs 40. The disc 29, Figs. 2 and 9, is formed with pins 50 adapted to be engaged, so as to hold the carrier firm, by a spring catch 51 having an inclined lower end 56. Each time the traveller rises, a pin 55 on a weighted pawl 53 carried by the traveller engages the end 56, and releases the carrier. The nose of the pawl then engages a lantern-wheel 57, and turns the carrier so as to bring another roller into action. As the traveller descends, the pawl is pressed outwards by the end 56 of the spring catch which again secures the carrier. The traveller comprises end-plates bent to engage the uprights 22, 23, and connected together in the rear by a plate 68 secured to a tube 88 carrying rollers 89 which run on an upright 24. The plate 68 has brackets 79 in which are mounted, by rods 80 and springs 82, a slotted frame 81. A chain 92, mounted on wheels 91, 93 carried in fixed brackets, has a pin and friction roller 94 which engages the slotted frames 81. As the axle 90 of the lower wheel is rotated by a crank or by other means, the roller 94 causes the traveller to move up and down. The frame 81 comprises two parallel plates between which the chain-wheels pass. The outer plate is slotted, as shown, to pass the axles 90. Mounted on studs 97 at the front of the carrier are bars 96 formed at their ends with hooks 99, 101 to receive the roller axles. Springs 98 press these catches into a vertical position. The hooks correspond in shape with the slots 32 so that an axle held by the hooks cannot rotate. In consequence, as the traveller rises, it rolls up a curtain on an axle in its upper hooks, and unrolls a curtain on an axle in its lower hooks, and vice versÔ. At each end of its motion it delivers up a roller to one of the carriers and receives a fresh one, the carrier being turned by the pawls 53. In this arrangement, the exposed parts of the curtains are stationary. In front of the bars 96 is mounted a plate 67 secured at its ends to plates 71 having lugs 75 carrying pins 74. These pins slide, under the influence of springs 76, in studs 72 passing through slots in the plates 71 and secured to the end-plates of the traveller. The plate 67 is prevented from rising or falling far enough to interfere with the carriers, by rods 78 secured to the plates 20, 21.
