Description
UNITED. STATES PATENT OFFICE.
GEVEDRA B. SHELDON, OF NEW YORK, N. Y.
-IMPROVEMENT IN FURNITURE-CASTERS.
Specification forming part of Letters Patent No. 137,251, dated March 25, 1873.
To all whom it may concern:
Be it known that I, CEVEDRA B. SHELDoN, of the city, county and State of New York, have invented anew and useful Improvement in Casters, of which the following is a speciiication:
The object of this invention is to render furniture and other casters more useful than they now are; and it consists in the arrangement of a series of friction-balls in a casing on and above the stand andbetween said stand and the cap or socket that is applied to the furniture-leg, the construction being such that the friction is greatly reduced and the casterwheel made to readily turn and conform to the motion of the piece of furniture moved.
In the accompanying drawing, Figure lisa longitudinal section, showingniyimprovement in an ordinary wheel-caster applied to the4 leg of a piece of furniture. Fig. 2 is a section of Fig. l taken on the line a: x. Fig. 3 is a section looking down from the line y y of Fig. l.
Similar letters of reference indicate corresponding parts.
In this example of my invention I show my invention applied to the ordinary wheel-caster; but I do not confine it to any particular kind of caster, as it is adapted to casters running on spheres or balls as well as wheels.
A is the stand or bracket. B is the wheel. Gis the fastening-screw. To the top of the bracket A I attach a corrugated cup, D, seen in cross-section in the drawing, with frictionballs E (more or less in number) on the bottom thereof. F is the head of the fasteningscrew. G is a cap, which is rigidly attached to the screw or fastening part ofthe caster by means of rivets H H or in any other manner. This cap is turned down at right angles, as seen at'I, and from the rim I it is turned under, as seen at J, thus forming an annular box or recess L on the outside of the cup D, in which recess is placed friction-balls K. The head of the fastening-screw rests on the friction-balls E. The upper edge of the cup D is turned outward into the annular box. This outer tier of friction-balls keeps in place the cap G and steadies the caster on the furniture.
Having thus described my invention, I claim as new and desire to secure by Letters Patent l. In combination with a caster, a casing composed of two or more parts, one of which is attached to the stand or bracket and the other to the fastening-screw or plate, with friction-balls between the two, substantially as shown and described.
2. The friction-balls K, arranged in the annular groove L formed between the inner side of the cap G and the turned-out flange of the cup D, as and for the purpose specified.
CEVEDRA B. SHELDON.
