CASTER FOR ANGLE-BAR FURNITURE.

Application led May 28, 1915.

To all fwwm t may concern citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Casters for AngleBar Furniture, of which the follow.- ingis a specification.

My invention relates to casters adapted to support furniture having legs or a frame comprising vertical angle-bar members, Such as metallic couches, divans, davenports, and the like. In such structures previously proposed a leg-supporting plate has been provided beneath the flanges of the angle-bar with ears struck upwardly therefrom riveted to the flanges of the angle-bar, the caster being revolubly mounted on a pintle secured in the leg-supporting plate.

My improved structure is an improvement on the above in that it provides a supporting frame of pressed metal so constructed as to be mounted upon the lower end of the angle-bar without the necessity of using rivets or other securing means. T0 this end a vertical flange extends upwardly from the leg-supporting plate to bridge across the opening of the angle-bar, this vertical plate being provided with end portions or ears which are bent around the flanges of the angle-bar. ln one forni of my device these ears are pressed against the outer surfaces of the angle-bar flanges to securely hold the structure in position, while in another form of my invention, these ears slidably engage the outer surfaces of the angle-bar flanges, the caster being held in position by a friction device mounted within the angle-bar and contacting the same and the caster frame. A top flange is also provided which extends between the flanges of the angle-bar and provides an upper journal for a revoluble pintle,which extends through the upper flange and the bottom flange or leg-supporting plate described. By the construction described, in either form, a strong and simple caster mount is provided which may be manufactured and assembled cheaply and quickly and presents a neat appearance.

In the following description the term Specification of Letters Patent.

Serial No. 30,895.

A33;-,caster is to be understood as including Be it known that l, ALBERT B. Diss, a

both the fixed and movable elements of the caster.

In order that a clearer understanding of my invention may be had, attention `is hereby directed to the accompanying drawings forming part of this application and illustrating certain embodiments of my invention.

In the drawings Figure l represents a side elevation of a caster removably secured to the lower end of an angle-bar, Figs. 2 and 3 arehorizontal sections taken on lines 2-2 and 3 3 respectively of Fig. l, Fig. l is a vertical cross-section through the caster supporting frame, the caster wheel, jaws and pintle being shown in side elevation, and Fig. 5 is a horizontal section similar to that of Fig. 3 of a modification in which the l(Saster frame is fixedly secured to the angle- Referring to the drawings, the angle-bar l is represented as having flanges l, l at right -angles to each other meeting in an apex 12. The caster-wheel or-rotatable element 2 is mounted between jaws 3 having a horizontal yoke portion 4c from which the pintle 5 extends upwardly. ln the preferred form of my construction the pintle is mounted to rotate and accordingly is secured at its lower end to the yoke ll of jaws 3.

The frame in which the pintle is journaled is formed from a sheet-metal blank pressed to form to provide a bottom flange 6, a vertical front flange 7 having ears 8, 8 at its ends and a top flange 9. The bottom flange 6 constitutes the leg-supporting plate for the caster and is of a generally triangular shape having one edge 6 constituting the hypotenuse of the triangle bridging across the opening of the angle-bar and other side edges which are approximately in the same planes as the outer surfaces of the flanges l, l of the angle-bar. The vertical flange 7 is bent upwardly from the edge 6 of the bottom plate 6, extends across the opening of the angle-bar and is bent around the edges of the flanges l to form the ears 8, 8 which as stated contact the rear surfaces of the flanges 1. rI`he top flange 9 is bent horizontally at right angles to flange 7 and is shaped to fit within the flanges 1 of the angle-bar, being of an approximately triangular shape, The pintle 5 1s Journaled in cylindrical openings in flanges 6 and 9 and is given an enlargement above the top flange 9, as by pressing the metal outwardly therefrom to form ears as shown at 10, to keep the pintle from falling out of its supporting structure. The pintle 5 is preferably provided with a bearing collar 11 below the bottom flange 6.

In the structure shown in Fig. 5 the caster is mounted fixedly in position by pressing the ears 8, 8 of the vertical flange 7 rmly into contact with the rear surfaces of flanges 1 of the angle-bar. In mounting this structure -it is merely necessary to slip the lower end of the flanges of the angle-bar between ears 8, 8, and the top plate 9 and the verticalflange 7 until the angle-bar -flanges contact the leg-supporting plate 6 after which the ears 8 may be pressed tightly against the outer surfaces of the angle-bar to clamp the structure in position. The structure illustrated in Figs. 1 to 4:, however, is made removable by the addition of a spring 12 which is formed preferably by bending a strip of spring metal into an approximately inverted U-shape having a depending leaf 12 adapted to lie against the inner surface of flange 7 and a leaf 122, connected by a horizontal yoke through which a hole is punched, through which the pintle extends, to support the spring in position. In this form of my invention, the ears 8, 8 are not pressed into securing engagement with the angle-bar but slidably engage the same. When the caster is mounted in position, the flanges ofthe angle-bar are slid between the ears 8, 8 and the flanges 7 and 9, the metal constituting flange 7 and ears 8 being bent to form slideways for the edges of the angle frame. Vhen the caster is pressed into position, the leaf 122 of the spring 12 engages the inner surfaces of the angle bar flanges acrossthe junction of the flanges as is shown in Fig. 3, the frictional engagement of the leaves 12 and 122 of the spring with the flange 7 of the caster and the flanges 1 of the angle-bar respectively, holding the caster frictionally in position. It is to be understood, however, that my invention is not limited to the use of the exact spring-holding means shown, but that the use of other forms of spring, performing the same function, is included within the scope of my invention. In the form illustrated the leaf 12 ofthe spring, which rests against flange 7 of the caster frame, prevents the spring from turning out of position, and also the bottom of leaf 12 may rest on the bottom flange 6 to support the spring.

Having described my invention, what I claim as new therein and desire to secure by Letters Patent of the United States is:
