Abstract: 18,551. Reynolds, F. L. Aug. 19, 1905, [date applied for under Patents Act, 1901]. Advertising. - Advertising-apparatus for street and other passenger cars is arranged for actuation, for example, above the car - windows, and consists of a flexible endless carrier, such as a sprocket - chain, movable in guides, and a number of signs each pivotally connected at one end to the carrier. The plane in which the carrier moves is inclined forward from the horizontal so that, the guides being suitably cut at one end of the apparatus, the free end of each sign falls forward to the front of the casing as the corresponding part of the rear half of the carrier reaches that end, and is then carried the whole length of the apparatus in full view. Half the signs are thus exposed while the other half are travelling behind them. The signs or cards H', H', &c., Fig. 1, are contained in open frames G<1>, G', &c. which are made of sheet metal, one side of each having a slot through which the display card may be inserted and removed. Each frame is pivoted to a sprocketchain A, travelling round sprocket-wheels B<1>, B' by means of a rod g, preferably forming an upward extension of one of the pivot pins of the chain, which passes through a tube fixed to one vertical edge of the frame. The upper end of each rod g is provided with a roller g<2> which always remains in one of the upper guide-grooves. The lower end of each rod is surrounded by a washer g<1>, which rests upon the chain A and supports the frame to which it is attached. The lower guide F, in which the chain moves, and the upper guide E, Fig. 3, may each consist of an outer channel beam with a narrower channel beam secured therein, and they are supported, e.g. by brackets f, e on the curved portion D in a car. When one sprocket-wheel B<1> is driven, e.g. from the axle of the car or a separate motor, through a shaft c and bevel-gear C, B, the free end of each frame G<1>, Fig. 4, as its rod g passes round the sprocket-wheel B<1>, falls forward against the front flanges e<1>, f<1> since the smaller roller g<3> at the top of the frame G', and the support g<4> which rests upon the chain, are able to clear, respectively, the inner flanges e<2>, f<2> of the upper and lower guides E, F which are partly cut away for a distance from the sprocket-wheel B<1> slightly greater than the length of the frames. As the rod g passes round the sprocket-wheel B<1>, the support g<4> is directed by a deflector f<4>, preferably formed by bending a part of the front flange f<2> adjacent to the cut-away part, into the grooves between the front flanges f <1>, f and e<1>, e<2>. The frame with its sign is then carried along the display space until the chain passes around the idle sprocket-wheel B', when the frame continues to the right into an extension of the upper and lower outer guides e<1>, f<1>. The extensions are not provided with inner flanges but are provided with wedge-shaped guides which engage the front of the frame. As the frame passes round the idle sprocket-wheel B<2>, it is drawn past other deflectors into the rear guide-grooves.
