THOMAS E. GOULD, OF BROOKLYN, NEW YORK.

FURNIT URE-CASTER.

Specification of Letters Patent.

Patented June 30, 1914.

Application filed November 4, 1913. Serial No. 799,133.

ToizZZ whom it may concern .Be it known that I, THOMAS GOULD, a citizen of the United States, residing at Brooklyn, in the county of Queens and State to the article in connection with which it is used.

The invention therefore consists of the detailed structural features substantiall las y the ap ended claim.

In t e accompanying drawing is illus trated the preferred embodiment of my invention wherein it will be understood that various changes and modifications as to the detailed construction and arrangement of parts may be made without departing from the spirit of the invention, and in which drawing Figure 1 is a side elevation of my caster. Fig. 2 is a vertical section of the same taken centrally about therethrough and trans- "versely toand at one side of the caster-wheel axis, said caster-wheel with a portion of its carrying bracket being removed. Flgs. 3 and 1 are inverted disassembled perspective views showing more particularly the annular race-forming portions of the casterwheel and attaching members of the device.

In carrying out my invention, I form the same of two castings, one of which, designated as 1, may be termed as the casterwheel bracket-carrying member, and the other of which, designated as 2, may be termed as the attaching or base member, the two conjointly constituting a turn-table like arrangement. The member 1 includes an annular or disk-likeportion 3 and'opposed pendant-arms or bearings 1 between which is received or carried'the caster-wheel 5, the axle 6 of which is journalecl in said arms or bearings. The disk or member 1 head has an annular recess or chamber 7 in its upper surface, the wall 8 of which is perpendicular upon its inner surface, while its outer surface is tapered or beveled from the outer edge or perimeter of the disk-forming portion of the member 1 inwardly and downwardly as at 9, thus thickening and accordingly reinforcing said, wall against liability of breakage. The member 1 also has a central opening or aperture 10 therethrough, the purpose of which will presently be apparent.

The member 2, which is suitably provided with preferably countersunk aaertures 11 at its corners to receive the attac ing screws or fastenings (not shownl. has formed in its lower surface also an annular recess or chamber 12 to receive the annular wall 8 of the recess or chamber 7of the member 1' within which recess or chamber 12 the latter turns, the unner ed e of said wall bearing upon the bottom of t e chamber 12; in other words the wall 8 of the recess or chamber 7 telescopes the wall of the chamber or recess 12 of the member 2, the same thus constituting a turn-table like arrangement, as will more fully appear presently.

Concentrically arranged within the recess or chamber 12 of the member 2, and integral with the bottom of said chamber, is an annular protuberance 13, and interiorly of the latter and spaced oif therefrom is also formed upon the bottom of said chamber 12 a hublike pivot 14 which is somewhat flared toward its base and which forms with said annular protuberance an annular depression or race 15 suitably ,furnished with a plurality of bearing balls 16 to provide a practically frictionless and sensitive bearing for the caster-wheel bracket at this point. The inwardlv flared and accordingly outwardly tapered pivot 14 extends through the a erture or orifice 10 of the member 1, w ich aperture snugly receives said pivot and whereby it is apparent lateral unevenness of movement or wabbling of the caster-wheel carrying bracket is prevented.

A rivet-like member or pin 17 is inserted through the tubular pivot 14 and suitably held in effective position to efi'ec't connection between the two members 1 and 2, one end of the pin.or rivet bcim formed with a revious to its insertion and the other end 0 said rivet being subsequently headed to prevent its displacement, said pin or rivet-like connection being such, however, as not to interfere with the swivellng action of the caster-Wheel carrylng bracket.

It is believed that from' the foregoing' therefore needs no further elaboration;

10 herein.

1 claim- A caster of the type described, including two members, one member having a rimedg'e annular portion and a central tubular 15 portion extending through a central orifice of the second member, said central tubular portion receiving and having applied thereto retaining means for said second member,

rmame said first-referred to member having a second annular portion depending therefrom intermediate said rim-edge annular portion and said central tubular portion to form with the latter an annular depression, said second member having an annular portion received between said rim-edge annular portion and said. second annular portion of the first-referred to member, and rotary bearing members contained within said annular de pression of the first-referred-to member.

in testimony whereof I allix my signature 30 in presence of two witnesses.
