CASTER.

SPECIFICATION forming part of Letters Patent No. 339,373, dated April 6,1886.

Application filed February 15,1886. Serial No. 191,995. 7 (No model.)

To all whom it may concern.-

Be it known that we, JOSEPH L. CARROLL and \VILLL-m H. CREIGHTON, both residents of Clarksvillc, in the county of Pike and State of Missouri, have invented certain new and useful Improvements in Casters; and we do hereby declare that the following is a full,clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure l is a perspective View from the inner side of the leg of apiece of furniture pro vided with our improved caster. Fig. 2 is a vertical sectional view taken on a line dividing the angle of the corner, and Fig. 3 is a perspective view of the three portions of the socket separated.

Similar letters of reference indicate corresponding parts in all the figures.

Our invention has relation to casters for furniture, and more especially for furniture having legs formed by two pieces placed at an angle to each other; and it consists in the improved construction and combination of parts of a socket for a caster, which socket is cast or made in three pieces, and may be secured in the corner formed by the two pieces of the leg, the socket serving to more securely attach the two pieces of the leg together, and the base-plate of the socket serving to hold the two portions of the socket together, as hereinafter more fully described and claimed.

In the accompanying drawings, the letters A A indicate the two pieces of the furnitureleg, which pieces are secured together at an angle, in the present drawings shown to be a right angle. The caster-wheel B is journaled between the lower bifurcated ends of a stem, 0, which turns in the socket, and the wheel or roller and the stem need no further description, as they will form 110' subject for any claims. The socket is composed of two longitudinal portions, of which one portion, D, will be fitted into the inner portion of the corner of the leg, and will therefore be termed the inner portion, 7 while the other portion, E, will be termed the outer portion. These portions or halves form portions or halves of either a cylinder of or a truncated cone, both closed at their upper ends, and the inner face of the outer socket-half is provided with an inwardly-projecting lug, F, which fits into a correspondingly-shaped recess, G, in the face of the inner half, the lug and recess being at the closed top of the socket. The inner side of the inner socket-half is formed with a ridge, H, near its upper eud,which ridge will fit into the corner of the leg, and at the lower end of the socket half it is formed with a semi-annular rib or flange, I. The outer socket-half is provided at its upper end with two perforated ears, K K, projecting obliquely in planes at a right angle to each other, and through the perforations of these cars the fasteningscrews which secure the socket to the sides of the leg pass The lower end of this half is formed with a short lip, L, at the lower end, and with a semi-annular rib or flange, M, above the lip.

The base-plate N has a circular perforation, 0, in its outer portion, into which the lower ends of the socket-halves may fit, and the inner edge of this perforation is formed withanotch, P, which corresponds in size to the lip upon the outer socket-half. The inner portion of the base-plate is triangular, and formed with perforations Q, for the reception of the fastening-screws, which pass into the lower ends of the portions of the leg, and thus secure and brace the portions of the leg, preventing them from spreading apart, while the screws at the same time secure the plate to the leg.

The socket-halves are introduced into the perforation by first placing the inner sockethalf with its lower end in the perforation, bearing with theportion above the rib or flange against the outer edge of the perforation. The outer half is thereupon inserted into the perforation, the lip registering with the notch in the inner edge of the perforation, whereupon the two socket-halves are revolved within the perforation, so that the halves will regain their proper places, when the lip upon the outer half will be diametrically opposite to the notch in the perforation.

The flanges will serve to retain the sockethalves in their proper position, and the lug fitting in the recess at the upper ends of the halves will also serve to retain the sockethalves in their proper places, so that when the base-plate has been placed in its position upon the socket-halves, and the entire socket and plate have been secured to the furniture-leg by means of the fastening-screws, the portions of the socket will be as firmly united as if they were made in one piece, and will brace the two pieces of the leg, besides serving as a socket for the caster-stem.

By making the socket in three pieces the cost of manufacturing the socket is reduced, the parts being easier to cast, which is the preferred mode of producing them, and the entire process of shaping, molding, and casting being greatly simplified.

Having thus described our invention, we claim and desire to secure by Letters Patent of the United States In a caster, the combination of a base-plate fitting within said recess upon the other part,

as shown and described.

In testimony that we claim the foregoing as our own we have hereunto affixed our signatures in presence of two witnesses.
