. GASTER BRACKET.

im utation filed Iiovember 10.1921. Serial No. 514,298.

To all whomit may concern Be it known that I, FRANK L. ROWNTREE, a citizen of the United States, residing at Meriden, county of New Haven, State .of Connecticut, have invented an Improvement in Caster Brackets, of whichth'e following is a specification.- p p This invention relates to casters and particularly to a bracket including a socket adapted to be secured to furniture to receive the pintle of a caster proper.

Itis an object of the invention to provide such a bracket of simple construction so that it may be easily and cheaply manufactured.

It is also an object to provide a bracket of this type which may be formed of sheet metal. p

It is a further object of the invention to provide an improved top bearing for a pintle in the socket.

It is a still further object of the invention to provide a bracket structure which may be secured to either a flat wall, the inside of an angle shaped le or the outside thereof.

D, with a very slight change.

With these and other objects in viewl have devised the improved bracket structure illustrated in the accompanying drawing, in which 1 Fig. 1 is a top plan view of what-1 call a straight bracket.

Fig. 2 is a front elevation thereof.

Fig. 3 is a top plan view of what 1 term an inside bracket showing it secured to the inside of an angle shaped leg of a piece of furniture.

Fig. 1 is a front elevation of the form shown in 3, a portion of the wall of the socket being broken away.

I Fig. 5 is a top plan view of what 1 term an outside bracket, and

Fig. 6 is a front elevation of the form shown in Fig. 5.

Referring to Figures 1 and 2 the bracket is shown as constructed of a pieceof sheet metal with its midsection bent to form a tube 10, the ends of the piece of sheet metal being brought together or nearly so at the back of the tube at 11 and are then bent away from each other, and in substantially the same plane to form wing portions 12 provided with any desired number OfClIlllBCl holes 13 to receive bolts or rivets to secure same to a support, such as the leg of a piece of furniture. as the wingportions 12 are in the same plane, this bracket is adaptedito be secured to the flat side ofthe support and I call it a straight bracket. The top ofthe tube is closed by means of integral lugs 1d the end of the tube, as shown. lnthe top .6 substantially triangular in shape bent over i of the tube or socket. I'provid'e a top bearing disc 15 formed of any suitable material,such as sheet metal Or fibre, and preferably provid'ed with a central raised portionlG 'forniing atopbearing for the end of-a pintle 17 "fora caster proper, 18, as shown in Fig. 4:,

this raised portion providing a substantially -;s mall bearing surface and allowing frees turning of the pintle in the socket. I preferably 101111 this disc separate from the ted and the end of the pintle curved to provide the small bearing surface,'if desired.

Any suitable means may be provided for retaining the pintle in the socket or tube bracket and insert it in the tube or socket .and retain it therein by the lugs 14: closing such as lugs 19 struck inwardly from the walls of the tube and adapted to coact with a groove 20 formed in the pintle, as shown in Fig. 1. \Vhen the pintle is inserted in the socket, as the walls of the tube are not connected at 11, the tube yields suificiently toallow the'lugs 19 to pass over the end 21 of the pintle, and then springs in to cause these lugs to enter the groove 20. A reverse oper ation will allow removal the socket.

Referring to Figures 3 and 4 the side portions or wings 12 are bent backwardly to ward the opposite sides of the tube so as to allow the bracket to be secured on the inside of an angle shaped leg 22 of a piece of furniture, the securing means being shown as rivets '23 although bolts or any other securing means may be employed. Otherwise, the structure of this socket is the same as'that shown in Figures 1 and 2. This form. of bracket 1 call an inside bracket.

In the bracket shown in Figures 5, and 6, the structure is also the same as thatfshown in Figures 1 and 2,.but the, side or wing portions 12 instead of being bent toward the tube, as in the form shown in Fig. 3, are bent to the rear so that the bracket may be of the pintle from secured to the outside of an angle shaped leg of a piece of furniture. 1 term this an outside bracket.

It will be apparent from the foregoing description that the bracket, including the socket, is very simple in construction and may be formed from a single piece of sheet metal. Also that it provides a very rigid structure which will effectively hold the caster in place, and at the same time will allow free swinging movement thereof.

Having thus set forth the nature of my invention, what I claim is:

1. A caster bracket comprising a substantially tubular socket, and a top bearing disc in the socket having a downwardly extending projection providing a thrust bearing for the end of a caster pintle.

Q. A caster bracket comprising a substantially tubular socket adapted to receive a caster pintle, and a separate'top bearing element for the pintle in the socket comprising a disc having a projection pressed downwardly from the body thereof.

3. A caster bracket comprising a piece of sheet metal with its midse'ction curved to form a tube and the end portions adapted to be secured to a support, and a top bearing for a pint-1e in said tube comprising a disc having a downwardly extending projection to abut the end of the pintle.

4. A caster bracket comprising a piece of sheet metal with its midsec-tion curved to form a tube and the end portions adapted to be secured to a support, a top bearing disc in the'tube, and lugs bent over the top of the tube to retain the disc therein, said disc being formed with a downwardly extending projection to abut the end of the pintle.

5. A caster bracket comprising a piece of sheet metal having its midsection' formed into a tube adapted to receive a pintle and the opposite ends extending away from each a other on one side of the tube, a topbearingidisc in the tube provided with 'a downwardly extending projection abutting the end of the pintle, and means for retaining a pintle. in

the tube. i

In testimony whereof I aflix my si nature.

FRANK L. RowNriiEE.
