UNITEDv STATES PATENT OFFICE.

JAMES CASTLE, OF TORONTO, ONTARIO, CANADA.

ADVERTISING DEVICE FOR CARS.

SPECIFICATION forming part of Letters Patent No. 375,987, dated January 3, 18E8.

Application tiled October l5, 1887. Serial No. 252.446. (No model.)

` the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

The object of my invention is to providea machine that ,will display movable advertisements in a suitable case adapted to be placed in av street-car, ythe operative force necessary to move the advertisements being derived from the movement of the bell-cord when the bell is rung for the purpose of giving a signal; and my invention consists of a case with a glass front,through which the advertisements may be seen, and a roller or rollers which carry sheets upon which the advertisements are printed, suitable mechanism being employedy to rotate the roller or rollers, so that all the advertisements will be displayed inturn.

In the drawings, Figure 1 is a vertical section of a car with my invention applied, Fig. 2 is a sectional viewT of the case and an end view of the roller. Fig. 3 is a modification of one part of my invention, and Fig. 4 is an end view of a car containing my invention.

Similar letters of reference indicate similar parts in the respective iigures.

A is the car.

B is the case, b being a glass panel through which the advertisements will be seen:

C is a roller which is supported on suitable bearings in the interior of the case, and on this roller the advertising-sheets c c c are secured; or, instead of having one roller with several sheets secured to it, two rollers, C C', might be used, and an endless sheet, c, might revolve around these rollers, as shown in Fig. 3. If different advertisements were printed on the sheet c, as the sheet revolved they would in turn be brought to view through the v glass panel b.

'Io one end of the roller C is secured the ratchet D.

E is alever pivoted to one side of a case and carrying at its lower enda dog, e, which engages the teeth of the ratchet D. To the up-r per end of the lever E is attached the cord F, which passes through the casing B and is attached to the bell-cord G.

H is a spring secured at one end to the cas ing B and at the other end to the lever E, as shown. This spring will have a tendency to pull the Alower end of the lever forward, and so cause the roller C to revolve.

h is a stop to prevent the spring from pulling the dog e out of engagement with the ratchet-teeth.

I do not contine myself to the precise construction and arrangement of mechanism describedabove for operating the roller, as the bell-cord is not always run through the carin the same position. Such an arrangement as I have described would answer if the bell-cord were run through the hole marked 1 in Fig. 4; but if the cord were run through holes l or 3 and the case occupied the position shown it would be better to have a lever, I, pivoted on the outside of the end of the car, to one end of which the bell-cord would be attached and to the other end the cord F to operate the lever E, which in such a case would enter through the back of the case and be attached to the lever, as shown in Fig. 2.

The operation willA be easily understood.

When the bell-cord G is pulled, the lever E will'be moved by means ot' the cord F against the force of the spring H, and the doge will be drawn back one tooth. When the strain on t-he cord F is released, the spring H will pull the lower end of the lever forward, and so causethe roller to revolve until the upper end of the lever comes in contact with the stop h. As the roller revolves the advertisements c c c will be all displayed in turn, no matter whether the arrangement shown in Figs. l and 2 or that shown in Fig. 3 is used.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. In combination with a car, a case, a roller journaled in said case and carrying an advertising-sheet, a ratchet-wheel upon one end ol' said roller, a lever pivoted in said case, a dog upon the lower portion of said lever to engage the ratchet-wheel, a spring attached to thecase and to the lever, and a cord con- IOO necting the bell-cord and the lever, whereby the roller is rotated when the bell cord is pulled, substantially as described.

2. In combination with acer@ glussfronted case secured in said car, :t rollerjournaled in said case and carrying a series of advertising- Y sheets, :t ratchet-wheel within the case and secured to one end of said roller, a lever pivoted in the ease above the roller, n dog curried by the lower portion of said lever to engage said ratchet-wheel, a springhaving one end secured to the case and its opposite end to the lower portion ot' the lever, and a cord connected with the bellcord and passing through the case and being secured to the le- 15 ver, whereby the roller is rotated when the bell-cord is pulled, substantially as described. In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
