IMPROVED TRUNK-GAMER.

@Llge l1thlllt were it in time finite tgatenttnt mating part at its smut.

TO ALL WHOM IT MAY CONCERN:

Be it known that we, LEWIS HORTON and JOSIAH A. McGAW, of Manchester, in the county of Hillsborough, and State of New Hampsl1ire,have invented a new and improved Trunk-Caster; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification,- in whichi t Figure 1 represents a front view of a trunl; provided with our improved corrugated swivel-casters.

Figure 2 represents a bottom view of the same.

Figure 3 represents a detached section of the caster.

Similar letters of referencelinclicatc corresponding parts.

This invention relates to an improvement in the construction and arrangement of casters for 't'runhs and other similar articles, and 'ccnslsts in a corrugated caster-roller hung in a frame that is swivelled on a pivot rigidly fastened to a plate thatis attached, by nails orserews, to the bottom of a trunk or other article, as hereinafter described.

The ordinary caster is attached to a frame with a shank that revolves in a ferrule or socket, and is easily broken and got out of order by the leverage strain upon the shanln To obviate thisdiiiiculty, we have devised a caster, the frame of which revolves on a fixed pivot fastened to a plate, and, at the same time, hears fiat upon the smooth surface of'the plate, whereby the weight of the trunk is supported without any strain'on the caster to bend or break it.

A represents a trunl ;,-on which is fastened a smooth metal plate, a, in which is set and fixed u pin, c, on which is pivoted allot-bottomed caster-frame, b, for supporting the corrugated roller (Z, that is hung in the sides a e. It will be ohs erved that the bottom of the caster-frame bi'ests always upon the plate a, when it turns on the fixed pivot-pin c, and thus prevents anystrain on the caster, sorthat a trunk or other article to which it is applied may lie-moved about in any direction without danger of brenlring the caster.

,Having described our invention, what we claim as new, and desire to sccureby Letters Patent, is-

The trunk-caster,consisting of the plate a, to whichthe plate Z: is hung by the pin a, said plate bearing between the two'arms e the corrugated roller d, all constructed as described, whereby the plate a is secured in place without the pin 0 entering the bottom of the trunk, and the plate I) allowed. to revolve in contact with the plate a without leverage, as herein shown and described.

The-above specification of our invention signed by us, this 30th day of November, 1867.
