SPECIFICATION forming` part of Letters Iiatent No. 588,783, dated August 24, 1897.

I I Application led September 21, 1896. Serial No. 606,460l (No model.)

To all whom t may concern,.-

Be it known that I, CHARLRSS. STAFFORD, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Advertising-Vehicles; and I hereby declare the following to bea full, clear, and exact description of the same. l

My invention relatespto advertising-vehicles; and it consists of the parts and the construction and combination of parts hereinafter described and claimed. A

Figure 1 is a view of my vehicle. Fig. 2 is a vertical section of the same on the line y y of Fig. 3. Fig. 3 is a' side View of the driving mechanism, the canvas being moved by ropes and pulleys. Fig. 4 is a plan'of the same. Fig. 5 shows the arrangement of parts when using sprocket-wheels and chains. Figs. 6 and 7 are modified constructions to be hereinafter referred to. p

The object of my invention is to provide a wagon or vehicle with movable iexible sides or surfaces and a mechanism interposed between these and the wheels of the wagon, so that the rotation of the latter will advance the movable surfaces periodically and inter-v mittently.

A is a frame of any suitable orvdesired form and construction mounted upon wheels B, so as to form a wagon or vehicle.

In the present case I have shown a device in the form of a rectangle of considerable height having a root of triangular cross-sec tion.

Between the ends of the frame, near the top and bottom, are drums or rollers C, so journaled that they will rotate easily, and upon these drums or rollers the flexible belt or advertising-surface O is disposed. VIn the present case I have shown one of these surfaces with its rollers upon each side ofthe structure, and it will be understood that these surfaces may be moved byindependent mechanisvm, or, if preferred, both'ma'y be moved by one intermediate mechanism.

,The belts or surfaces are passed over the rollers up and down. There is a sufficient number of rollers tovprovide for as great a surface as may be desired, and the belts being endless will be propelled by the rotation shaft.

of the rollers, so as to advance them as may be desired.

The rollers may be driven in various ways, either by intermeshing gear-wheels fixed upon the ends of the roller-shafts and engaging each other in the manner to rotate the rollers in the proper direction with relation to each other, or the roller shafts may have sprocket-Wheels fixed upon them adapted to be driven by chains which pass over the wheels. f y n The rollers at the bottom of the apparatus are thus variously connected, Whilethose above are free to move independently as, the belt or surface passes over them. In some cases it may be found advisable to fix ropes in the edges of the belt-surfaces, the ropes passing over suitable pulleys, by which they are moved.

It Willbe manifest that rope or belt pulleys' could also be fixed upon the roller-shafts to transmit motion, but these various transmitting devices being well known I do not especially limit myself to either.

The term gear is generally used to indicate any intermediate driving mechanism.

My arrangement enables me to use av belt or surface of considerable length and adapted to contain a large number of advertisements in arcomparatively small space.

The lower rollers are each positively driven, whichv overcomes the tendency ofthe folds of the belt' slipping at points intermediate of the e'nd rollers and also enables the said intermediate portions to be positively acted on to give a uniform motion to all parts of the belt, insuring an easy movement to the latter without danger of cramping or binding.

In order to transmit the power to drive the rollers and belts,various combinations of gearing may be employed, which gearin gis driven from the Wheels of the vehicle. In the present case I have shown two longitudinal shafts D, journaled at theends of the vehicle and having driving devices fixed tothem to intermesh with those upon the drums or rollers. These shafts have also fixed upon them bevelgears E, which engage with the corresponding gears F upon a horizontally-journaled This shaft has a pinion Gr fixed upon it, and the pinion is engaged by a gear-wheel IOO H, mounted upon another horizontal shaft, which in turn carries a pinion I, and this pinion is engaged by a mutilated gear-wheel J upon still another shaft K. This mutilated gear-Wheel has teeth upon one-third or other desired portion of its periphery. In the present description I have shown it having teeth upon one-third of its periphery. Upon one side of this gear-wheel is a projecting spur L, which engages a projecting pin or lug M upon the shaft of the gear-wheel H when the teeth of the mutilated wheel have arrived at a point which will cause them to mesh with the pinion I. This guide always places the teeth of the gear and pinion with such relation to each other that they are sure to mesh properly and not strike against each other in opposition.

Upon the same shaft with the wheel J is another gear-wheel O, which in turnengages with a mutilated gear-Wheel `l? fixed upon the shaft Q. This gear in the present case isrshown as having teeth upon one-fourth of itsperiphery, and it also has a guide-lug P', which engages alugl2 upon the gear-wheel O,-so as to insure the'correct intermeshing of the teeth. vUpon the shaft of the gear P is another gear-Wheel `R, and this engages -With a pinion S upon the driving-shaft or axle T.

`It Will be manifest that the mutilationof the .gears may be varied in any desired proportions, the'duration ofmovem'ent produced when the gears are `in mesh being the point tobeconsidered, and it `will bemanifest that the train of gears here described is rsimply representative of any train `which will produce equivalent results.

The operation will then beas follows: The vehicle being drawn or propelledin any usual or suitablemanner, the shaft T will be rotated and will transmit powerthrough the various gears to rotatethem when all are in mesh and to interrupt the rotation when either of the mutilated gears are out of mesh with their fellows. The proportion o'f the smooth to the gear part of these wheels and therelation of their diameters aresuch that the belts or surfaces upon which the advertisements are. displayed will be moved at each engagement a suicient distance to bring a newadvertisem'entupon the surface and cause the former one to disappear, or, if-preferred,twoor more may be exposed at one time.

.In order to enable the vehicle to turn corners, it is necessary to provide Aa clutch or clutches, as `shown at U, one part being fixed upon the Vshaft Aand the other slidable upon the key or feather and preferablyactuated by a spring, as shown-at Vf, sothat the two parts are normally kept in mesh; butif either wheel `runs fasterthan the other one or both the Vclutches lwill act, the parts :sliding over each other, so that thefaster moving `wheel will be allowed to travel temporarily independentof the remainder of the ishaft, and when the 1machine is again moving the clutch V action fis ysuch `as torevolvetheshaft from the wheels.

In Fig. 3 the pinion S is shown as fixed upon the main wheel-shaft.

In Figs. G and 7 I have shown the shaft X as a supplemental one journaled parallel With the main wheel-axle T', which in this case is stationary. The driving-gears S are fixed to the wheel-hubs and engage corresponding gears W upon the ends of the shaft X, the rest of the mechanism operating as before described. l

Having thus described my invention, what I claim as new, and desire to sec ure by Letters Patent, is-
