ROLLER.

Specification of Letters Patent.

Patented Aug. 29, 1911.

Application filed October 15, 1910. Serial No. 587,243.

To all whom it may concern:

Be it known that I, Jnssn S'roRoK, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Rollers, of which the following is a specification.

This invention relates to rollers and more particularly to that type which are adapted to be used as trucks for the transportation of heavy articles such as logs, machinery, crates, etc. Heretofore in moving logs or the like it was customary to place a plurality of rollers beneath the same which had to be picked up as the tail end of the log passed over the same and placed under the forward end. This operation had to be repeated many times according to the distance the log was moved and it is the object of this invention to provide a supporting roller by which logs may be moved any distance without altering the initial position of the roller beneath the log.

A further object of the invention is to provide a roller of this character which will be compact and which will have very little height so as to obviate raising the log or other article any great distance.

Further objects of the invention will appear as the following specific description is read in connection with the accompanying drawing which forms a part of this application, and in which:

Figure 1 is a side elevation. Fig. 2 is a bottom plan view. Fig. 3 is a longitudinal section. Fig. 4 is a transverse section. Fig. 5 is a perspective view of the shaft removed from the roller.

In the specific embodiment of the invention illustrated herein I have shown a shaft 1 having a central collar 2 arranged thereon and end collars 3. Where the roller is shorter the intermediate collar 2 will be omitted and if the roller is desired longer than the one shown more collars will be interposed throughout the length of the shaft to separate the rolls 4. The collars 2 and 3 are provided with recesses 5 forming diawhich the rollers 4 are mounted, the end thrust of said rollers 4; being taken against the ends 7 and the intermediate web 8. In order to hold the shaft in position within the shelf member, bearing brackets 13 are secured across the ends and held in place by suitable bolts, lag screws or the like. As shown in side elevation the rollers project only a sufiicient distance below the lower edge of the shelf to raise the same above the ground and to prevent contact thereof with small obstructions on the ground.

Having thus described the invention, what is claimed is .A device of the class described comprising a shelf having a semi-cylindrical recess, recessed end members on the shelf, an intermediate web connecting the sides of the shelf and having a recess therein, a shaft having a plurality of collars with square sides seating in said recesses of the end members, and the web, anti-friction devices arranged on said shaft between the collars, supporting rollers arranged on said antifriction devices and projecting below the lower edge of said shelf, said rollers arranged between said end members and web, and means carried bythe end members for securing the shaft in the recesses of the end members and web.

In testimony whereof I affix my signature in presence of two witnesses.

JESSE STORCK.
