OLE PEDERSON, OF AURORA, ILLINOIS.

FURNlTURE-CASTER.

SPECIFICATION forming part Of Letters Patent N0. 498,297, dated May 30, 1893.

Application filed August 30, 1892. Serial No. 444,5(l0. (No model.)

To all whom it may concern.-

Be it known that I, OLE PEDERSON, a citizen of the United States, residing at Aurora, in the county of Kane and State of Illinois, have invented certain new and useful Improvements in Furniture-Casters, as set forth in the accompanying drawings, forming part of this specification, inwhicl Figure l,is a side view of a caster embodying my invention. Fig. 2, is a vertical sectional view of the same. Fig. 3, is an inverted perspective view of the sleeve or socket piece. Fig. l, is a perspective view of the stem.

My invention relates to furniture casters and especially to that class denominated roller casters, and my invention consists of the constructions and combinations of devices which I shall hereinafter fully describe and claim.

To enable others skilled in the art to which my invention appertains to make and use the same I will now describe its construction and indicate the manner in which the same is carried out.

In the said drawings A represents a bellshaped supporting frame or shell of suitable design and ornamentation, having one side cut-away and provided with ears or lugs a through which the pintle or shaft B for the ground-roller or rollers C extends whereby said roller or rollers are mounted to turn within the cutaway side of the frame as shown in Figs. 1 and 2.

The top surface of the bell-shaped frame or shell A which overhangs the cut-away side, is provided with a slot or opening 1), within which is mounted an anti-friction roller D, against which the flange of the sleeve or socket piece E is supported and upon which it rotates.

Inside of the bell-shaped frame or shell A and depending from its top wall is a short cylinder 0 which is suitably braced and reinforced by a web cl which connects it rigidly with the inside of the side wall of the frame or shell opposite to the cut-away side portion, and through the cylinder or bearing 0 is passed the stem S of the caster, the said stem having its lower end upset or riveted so that the frame or shellA will not become detached when the caster is in position. The stem is cylindrical to form smooth journals except at a point near its center or just above the top of the shell A, where it is formed with a square, or approximately square, portion 6, and from this point the stem is grooved to its outer end at f, to receive a spring plate or tongue g, oneend of which is riveted or se-' .cured to the stem while the other end is free and curved outwardly beyond the plane of the sides of the stem and then carried over and seated in the grooved top of the stem. Upon the cylindrical portion of the stem be tween the under side of its squared portion 6 and the top of the shell A, is a loose washer F, and in the underside of the flange h of the sleeve or socket-piece E is formed a recess Z in which this washer is seated when the sleeve is in place whereby the washer receives the weight of the furniture.

' The sleeve or socket piece E has a cylindrical bore through which the upper end of the stem passes, and also has formed at the base of this bore a square opening or recess e adapted to receive the squared-portion of the stem to prevent the stem rotating; the said socket-piece or sleeve being removably held to the stem by the friction caused by the spring plate g binding against its inner wall. The upper end of the sleeve or socket piece is chamfered on the inside, and formed with projecting prongs or points m, which are notched or serrated on their outer surfaces whereby when the socket-piece is driven into the furniture these points are spread slightly apart to securely hold the socket-piece to the furniture.

A- caster constructed as above described contains but few parts, is of an ornamental nature, is not liable to injury and when in place makes a strong, simple, and effective roller support for furniture.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is I 1. In a furniture caster, the bell-shaped shell cut away at one side, and provided with a bearing for the stem, in combination with said stem loosely fitted in said bearing and provided with a spring-plate or tongue, the ground-roller mounted within the cut-away portion of the shell, and the sleeve or socketpiece engaging said stem and adapted to be IOO inserted in the furniture, substantially as herein described.

2. In afurniture caster, the bell-shaped shell cut away at one side and having the central depending stein-bearing the ground-rollers mounted in the cut-away portion of the shell, and a web or brace joining the bearing with the side wall of the shell,in combination with a stem loosely fitted in said bearing and provided with a spring-plate or tongue, a socketpiece or sleeve removably fitted to the stem and having a flanged lower end, and an antifriction roller upon which said flange rests, substantially as herein described.

3. In a furniture caster, the supporting shell or frame with its ground-roller, in combination with a stern having a centrally-disposed squared-portion, a washer loosely placed on said stem between the under surface of the squared-portion and the uppersurface of the shell or frame, and a socket-piece having a flanged lower end provided with a recess for the washer, said socket-piece having also an internal square recess for the reception of the squared portion of the stem, substantially as and for the purpose described.

4. In a furniture caster having a stem, a socket-piece removably fitted thereto having its upper end internally chamfered and provided with projecting roughened points adapted to spread apart when introducing the socket piece in the furniture, whereby said piece is retained in place, substantially as herein described.

5. An improved furniture caster, consisting of the bell-shaped shell cut-away at one side and provided with a depending central bearing and bracing-web, the ground-roller in said cut-away portion, the anti-friction roller, the stem mounted in said bearing and provided with a central squared-portion and longitudinal groove, a spring-plate in said groove, a washer under the squared portion of the stem and resting upon the shell, and a socket-piece fitted to the stern having a flanged lower end provided with a recess for the washer and square recess for the squared portion of the stem, said socket-piece having its upper end formed with roughened projections or points adapted to spread apart when the socketpiece is fitted to the furniture, substantially as herein described.
