FRANK SEPTIMUS DEVONTEAUX SCOTT, OF LONDON, ENGLAND.

ADVERTISING DEVICE.

SPECIFICATION forming part of Letters Patent No. 574,277, dated December 29, 1896.

Application filed May 23, 1896- Serial No. 592,751. (No model.) Patented in England November 21, 1895, No. 22,198.

To all LU/1,0777, it may concern:

Be it known that I, FRANK SEPTIMUS DEV- ONTEAUX SCOTT, engineer, a subject of the Queen of Great Britain and Ireland, and a resident of 25 Upper Bedford Place, Russell Square, London, England, have invented certain new and useful Improvements in and Relating to Advertising Devices, (for which I applied for Letters Patent in Great Britain on November 21, 1895, No. 22,198,) of which the following is a specification.

This invention relates to displaying movable advertisements on vehicles, such as omnibuses, tram-cars, carts, and the like.

In order that the invention may he better understood, reference is made to the accompanying sheet of drawings, in which- Figure 1 illustrates an elevation of an omnibus, showing the invention in the proposed position. Fig. 2 is a front view of the mechanism for imparting a continuous movement to the strip containing the advertisements when the drums or rollers are revolved. Fig. is a plan of same. Fig. 4 is also a plan, but with the upper plate removed. Fig. 5 is a side View. Fig. 6 shows the gear for driving the mechanism above referred to. Fig. 7 is a sectional detail view.

Similar letters of reference indicate like parts where they occur throughout the views.

In carrying out the invention I arrange either inside or outside the vehicle and in the most convenient position two drums or rollers A and A, mounted upon spindles B and B and supported by the upper and lower plates O and O of a suitably-shaped frame D. To each drum is attached one end of a strip, E, of calico, transparent parchment, or other suitable material, containing a number of advertisements. Said strip may have elastic or other spring ends and may be of any suit-able length, according to the number of advertisements it is desired to display. Each end portion of said strip is wound upon its respective roller, while the portion between the rollers is earried either around the vehicle inside or outside or along each or both sides, or it can be arranged in any other suitable position. In order to impart a continuous or, if desired, intermittent rotation to these drums or rollers, so that the end portlons of the strip E will wind first upon one roller and then, when this roller is, say, full, wind upon the other roller, I secure to the roller-spindles B and B the toothed wheels F and F, both of which gear with a similar wheel G, loosely mounted upon the spindle G, on which is also fixed a cam H, having a peeuliarly-shaped circumferential groove H.

Two clutch-sleeves I and I, each having a tooth or projection J, are arranged upon the spindles B and B and are caused to slide either up or down, to engage or he disengaged from the clutch-racks K and K, formed on the upper ends of said rollers A and A, by means of the levers L and L, one end of which is pivoted to the brackets L and L and on the other end are formed the pins L and L to engage the groove II in the cam II. The 10- vers L and L embrace and connect with loose collars situated on the sleeves I and I, so that said sleeves can rotate with their respective spindles, and the springs L may be used to facilitate the disengaging of the clutches.

To regulate the speed of the cam H, so that one drum shall not be put into gear until the strip is entirely run off same and the other or full drum simultaneouslythrown out of gear, I arrange beneath the upper plate O a ratchetwheel M, having a suitable number of teeth and provided with a spring-pawl M to prevent any backward movement. This wheel M is rotated by an arm M secured to the roller-spindle B, so that at each revolution of said spindle B this arm strikes a tooth of the ratchet-wheel and slightly turns it. To the spindle of this ratchet-wheel is also secured an arm N, which in like manner rotates another ratchet-wheel N, attached to the camspindle G. It will be understood that according to the length of the strip E and the speed at which the advertisements are required to move so it would be necessary to increase the number of ratchet-wheels proportionately. hen the strip E has run off either roller, it momentarily stops until the next tooth of the ratchet-wheel N is moved by the striking-arm N. To effect the rotation of said drums or rollers, I attach to the hub or other convenient part of one, or, if necessary, more than one, of the vehicle-wheels (preferably the rear ones) a toothed ring or wheel 0, to engage with a corresponding wheel 0, connected with the lower end of a vertical rod 1, which is suitably supported by the brackets P and bearings I" and extends to the upper part of the vehicle and carries on its end a toothed wheel Q, which imparts a rotary movement to the wheel G on the eamspindle aforesaid through the medium ot the wheel Q.

To the vertical rod P is secured a ratchetwheel R, the spring-pawl for which is secured to the wheel Q, which is arranged loosely on said rod, so that the mechanism for rotating the rollers carrying the advertising-strip IE will only be put into operation when the vehicle is going forward.

To allow for any vibratory or other movements of the vehicle when going, so that the driving-wheels O and 0 shall be always in gear, I form upon or attach to the bevel-wheel O asleeve 8 to receive the lower end of the vertical rod P. This rod connects with said sleeve by the pin or other suitable projection S, which is free to move either up or down in the slot S according to the movement of the vehicle.

\Vhen the vehicle is set in motion, the drums or rollers A and A are caused to ro tate and the strip, or the portion of it that can be wound, passes "from one drum or roller over the pulleys or reels onto the other drum or roller, consequently displaying in succession any suitable number of, say, different 3 advertisements. i

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In mechanism for advertising pu rposes, the combination of the rollers A and A carrying a strip of calico or other suitable material containing ad vertisenients,with a frame D carrying the spindles 3, '3 and oi the spindles l3 and 13 having upon them the rollers A and A which carry the strip I while on G is the cam II: having a groove II. in which two levers L and Ii engage so as to cause the clutch-sleeves I and I to engage or be disengaged from the cl utch-racks K and K substantially as described.

2. In mechanism for advertising purljioscs, the combination of the rollers A and A carrying a strip of calico or other suitable Jmaterial containing advertisements, with the wheels F F I and Q with or without (3 for imparting movement to the spindles l3 and II carrying the rollers A and A, the wheels sim i-- lar to M N and striking-arms M: N to regulate the movements ol the cam ll so that its speed shall be in proportion to the length ol
