. CASTER.

.SPECIFICATION forming part of Letters Patent No. 314,957, dated March 31, 1885.

Application tiled September 10, 1884i (No model.)

To all whom, it may concern:

Be it known that I, STEPHEN C. MENDEN- HALL, a citizen of the United States, residing at Richmond ,in the county of Vayne and State of Indiana, (present business addressCinc-innati, Ohio,) have invented certain new and useful Improvements in 'Iops for Furniture- Casters and in Tools for Making the Same, of which the following is a specification.

The object of the present improvements is to provide a simple and secure means of fastening to the pod of a castertop the cap which retains the horizontal anti-friction rollers within said pod. To this end said pod is formed with a fiange at the bottom, having a chainfered edge, over which the upper portion of the rim of the cap is turned, either on a lathe or by a suitable die, to be hereinafter more fully described.

In order that my invention may be more fully understood, I will proceed to describe it with reference to the accompanyin g drawings, in which- Figure I is a sectional view of the compressing-die employed for iiXing the two part-s of the caster-top together, the caster-top being shown therein in side elevation. Fig. II is a perspective view of the complete caster. Fig. III is a vertical section of a caster-top with the spindle in place therein, the cap being shown in position to he upset. Fig. IV is a similar view showing the top complete.

The pod 1 of the improved caster is made in one or two parts, preferably, however, in two, as here shown.

It is provided at the bottom with a circular ange, 2, having downwardly-projecting rim 3, the upper edge of which is chamfered, as shown in Figs. III and IV. When a two-part caster-pod is employed, a circular smooth ring, 4, may be placed Within the same to afford a smooth bearing for the horizontal anti-friction rollers 5. The cup 6 is made of wrought or malleable metal of such dimensions as to slip loosely over the rim of the pod l, as shown in Fig. III.

r:Phe anti friction rollers and ring being placed in position and said cup slipped on, the top is placed over a centering-pin, 7, and a die, 8, having a beveled face, 9, being placed over the top, is struck smartly with a inallet. 5o The top then assumes the shape shown in Fig. II, its Vparts being inseparable, by reason of the upset lip 10 of the cup 6 engaging over the chamfered surface of the pod-rim. It will be seen that not only is the cup held onto the top of the pod, but the two parts of the pod are themselves held rigidly together.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent: l

In combination with a pod for the top of a furniture-caster, having horizontal annular flange at the bottom, a ring or cup having up setlip engaging with said ilange, substantially as set forth. y
