Abstract: 19,004. Fotheringham, C. K., and Laing, A. R. Aug. 12. Plates and the like, travelling.-A clock-controlled motor moves advertising cards from the front of a magazine into position for display, and then to the back of the magazine. The carriers have saddles, which deliver the cards up to a recessed sprocket-wheel having a pivoted guide-tongue in the recess, while they travel from the front to the back of the apparatus, and receive them back on their other sides. The magazine comprises a pair of inclined bars, flared at their upper ends and hooked at their lower ends to take up and deliver up the cards easily; and a pivoted gate is provided to cause the cards to escape singly to the carrier. Detachable clutch devices may connect up the apparatus to their driving-shaft. A pin-wheel 21, Fig. 2, in the clock mechanism strikes a lever 23 with a counterweight 24 and, tensioning a spring 39, brings a catch 40 on an arm 37 under a pin on a lever 31 pivoted at a point 28. On the release of the lever 23, the spring 39 draws up the arm 37 and the weighted lever 31, thereby removing a stop 33 from a fan 34 on a motor 20. The motor 20 then rotates a shaft 49, an arm 29 of the lever 31 having moved from its engagement with a broken rib 26 on a wheel 25 attached to the shaft 49. The wheel 25 rotates, and a cam 42 upon its shaft 49 draws in a rod 45 against the action of a spring 48, thereby drawing back the arm 37 by means of the bent end of the bar 45. The holder 40 releases the rod 31, which falls under the action of the weight 32 and leaves the rod 30 to rest on the rib 26 until the gap in the rib 26 is reached; whereupon the rod 31 falls into engagement with the fan 34 and stops the motor 20. The travel of the wheel 25 is transmitted by bevel and other gearing to a sprocket-wheel 61, Fig. 5. Saddles 66 on a. pair of chains loosely carry rods 67, Fig. 8, from which advertising plates depend. Each period of operation of the motor 20 carries the wheel 61 round once, and carries a new rod to the top of the wheel 61. A plate rising up the front of the machine meets a deep slot 70 in the wheel 61, having a switch-piece 69 attached to a controlling weighted lever 72, and the rod falls into the slot 70 and is carried round. At position B the weight 72 turns the piece 69 over; and at position C,. the rod emerges on to the opposite side of the saddle to that which it was on before. It then travels step by step down to two pairs of side rods 74, 75, enters their V- shaped mouths 78, leaves the chains, and slides down to the other advertising rods 67. A rotating wheel 62, carrying the chain, also has attached to it a disk 86 with a cam-groove 87, which controls an arm 83, pivoted at point 82, through levers 91. When the machine is at rest, a knife-edge 84, Fig. 10, on the arm. 83 stops the foremost rod 67. When the wheel 86 rotates, the blade 85 rises and cuts off a liberated rod 67, which passes on, and, on falling, allows another rod to pass up to the blade 83. The liberated rod reaches the chain 65, and is lifted on a saddle step by step to the top of the apparatus, and the previously described steps are repeated.
