WALTER C. WALLIS, OF HOPE, ARKANSAS.

'rnansr'onrn rion DEVICE.

- Application filed June 29,

'1 '0 a whom it may concern:

Be it known that l, WALTER G. WALLIS, a citizen of the United States, residing at Hope, in the county ofHempstcad and State of Arkansas have invented new and. useful Improvements in Transportation Devices, of which thefollowing is a specification.

Thisinvention relates to transportation devices, the object in view being to produce a rolling carrier for merchandisein general, which may be operated either by animal or mechanical power, the container being in the form of a hollow cylinder to which access maybe had for introducing and removing the merchandise, said container also operating as an eiiicient road roller, thereby not only preventinginjury to the road surface but in reality improving road surface in a manner similar to the ordinary road roller' now in common use.

A further object f the invention is to provide novel driving mechanism for the transportation device, whereby the latter may be driven by engine power, in a simple and direct manner without any possibility of injuring the road surface due to the presence of the driving mechanism.

A further object of the invention is to provide in connection with a plurality of hollow cylindrical containers, '2. frame in which said containers are journaled, and.

# means for permitting one of the containers to turn relatively to an adjacent container in order that the device as a whole may be steered either when operated by animal or mechanical power.

With the above and other objects in view, the invention consists in the novel construction, combination and arrangement of parts, as herein described, illustrated and claimed. In the accompanying drawings:- Figure 1 is a side elevation of a transportation device embodying the present invention, the same being shown as equipped with an engine for driving the same.

Fig. 2 is a plan view thereof. Fig. 3 is a vertical longitudinal section taken about in line with one of the flexible driving elements.

' Fig. 4 is a side elevation omitting the engine and showing the device equipped with a draft animal appliance. I Fig. 5 is an end elevation of one container showing the same reticulated and. provided with a door. i

number of containers coupled together by a commonframe in which they are jour'naled.

In the preferred embodiment of this inf" vention, the transportation device comprises a plurality of hollow cylindrical containers l and 2 and as indicated in Fig. 6,,one or may be provided in accordance with the manufacturer and which the device is to be put in pract1ce'.' I

The cylindrical containers-1, are provided thereof or in one or both ends or heads thereof as indicated in the drawings. Each of the containers is also provided with end journals 5 which are received in journal boxes, 6 and 7 in the substantially paralle side bars 8 of a truck frame, the latter being shown as embodying in addition to the side de r o h the particular use' to leither in the cylindrical wall bars 8, a cross member or platform 9 upon an engine of any preferre heir/ 2 designat generally at A. I i

- In the preferred embodiment of the invention, each of 'the containers 1 and 2 is provided adjacent to the center thereof with annular depression 10 containing sprocket teeth 11 around which passes one of a plurality of sprocket chains 12, said chains passing around sprocket wheels -15 on the engine shaft 14. The depressions 1O enable the chains to operate within the outer or peripheral surface of the cylindrical containers, thereby preventing any possibility of injuring the road surface over which the device is being drawn or propelled. In some cases it may be necessary to drive only one of the cylindrical containers while in other cases the driving means may extend to one or more additional containers as indicated in the drawings; a

the engine and the con- In additionto tainer driving means hereinabove described, a draft appliance designated generally at B may be employed, the same being shown for convenience as comprising the draft pole or tongue 15 and the attaching bars 16 which are connected hereinabove referred to. In order to permit the device to be readily steered or turned, thejboxes 6 are shown as mounted for fore andaft' movement in slots or guide ways 17 in the side bars 8 of the frame so that in view of the fact that the bars the draft mechanism are attached to. said boxes 6, the forward container will be turned,

at an angle in accordance with the direction followed by the draft animal or animals, the

depression 10 in the forward container preventing the sprocket chain from jumplng oil the teeth engaged thereby. It will be understood that lnstead of sprocket wheels "and,

chains, pulleys and belts or gears may be employed for driving the device.

ance than an ordinary wagon or truck carrying the same load for the reason that the cylindrical containers have a broad extended surface and cannot sink into the road surface as in the case of ordinary truck wheels. Furthermore, the cylindrical containers act as road rollers and tend to improve rather than injure the road surface over which they ass. v p Having thus described my invention, I claim 1. A transportation device comprising a pair of hollow cylindrical containers arranged one in advance of the other and having their axes normally'parallel, a frame in which said containers are journaled, an engine mounted on said frame, driving means connecting said engine with one' of said containers, the frame comprising substantially horizontal side bars formed with longitudinal slots, journal boxes slidable in said slots, and container end journals working in said boxes, whereby the axes of the containers may be thrown out of parallel relation to each other for steering purposes.

2. A transportation device comprising a pair of hollow cylindrical contalners arranged one in advance of the other and ha ving their axes normally parallel. a frame in which said containers ar ournaled, an engine mounted on said frame driving means connecting said engine with one of said containers, the frame comprising substantially horizontal side bars formed with longitudinal slots, journal boxes slidable in'said slots, container end journals working in said boxes, whereby the axes of the'con tainers may be thrown out of parallel relation to each other for steering purposes, and yieldable means in front and rear of said journal boxes for centering the same.

In testimony whereof 1 aiiix my signature in presence of two witnesses.
