Specification of Letters IPatent.

Patented Apr. at, iota.

Application filed July 31, 1912. Serial No. 712,474.

To all whom it may concern:

Be it known that 1, CHARLES J. ADAMS, a citizen of the United States, residing at Hatfield, in the county of Mingo and State of est Virginia, have invented certain new and useful Improvements in Casters, of which the following is a specification.

This invention relates to improvements in casters and its object is to provide a caster whose casing is provided with an angular slot in either face through which the axle of the caster passes. The slots are somewhat V-shaped but with one side shorter than the other and when the extremities of the axle pass through the short side of the slot the casing is raised clear of the surface upon which the device stands;

when the axle is disposed in the opposite side of the slotted portion the casing will be thrust down upon the surface upon which the device is disposed.

The invention consists in the combination and arrangement of parts to be hereinafter fully described in the following specification, pointed out in the claim and illustrated in the accompanying drawing which forms a part of the specification and in which- Figure l'is a perspective of my improved caster. Fig. 2 is a side elevation with'the parts in relatively changed positions.

Like reference characters indicate corresponding parts throughout the several views.

My casing comprises a pair of sides 1 and 2 united at the top by a portion 3 and at the lower extremity of the side of the casing and one of whose sides is shorter than the other.

8 is the wheel provided with an axle 9 adapted to extend through the slotted portion of the sides 1, 2.

The formation of the slot 6 is such that when the axle 9 passes through the shorter side of theslot the entire casing is lifted off the sustaining surface or floor upon which the device may travel but when the axle is disposed in the other side of the slot 6 the lips 5 of the casing will be thrust down upon the sustaining surface; the purpose of this construction being to take the weight ofi the wheel 8 when the piece of furniture provided with the-caster is at rest. The top 3 of the casing is provided with the usual stem 10.

' What is claimed is y In a caster, an angularly slotted casing, the slotted portions of said casing comprising a long and a relatively short side diverging from a common apex, and a wheel provided with an axle capable of removable disposition in the short side of the slotted portion of said casing whereby the casing will be supported upon the wheel, or, of removable disposition in the relatively long side of the slotted portion of said casing whereby the wheel will be thrown forward with relation to said casing and thereby relieved of the weight of the same.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two subscribing witnesses.
