FURNlTURE-CASTER.

SPECIFICATION forming part of Letters Patent No. 698,963, dated April 29, 1902. Application filed November 18, 1901. Serial No. 82,708- (No model.)

To all whom it may concern:

Be it known that 1, JOHN W. KENNEDY, a citizen of the United States, residing at Cecil, in the county of Berrien and State of Georgia, have invented certain new and useful Improvements in Furniture-Casters; and I do declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in furniture-casters.

The object of the invention is to provide a caster applicable to beds and other articles of furniture and having a spring-frame carrying a plurality of caster-wheels, the construction being such as to relieve the furniture of the injurious jars and shocks produced in moving the same from place to place and to obviate the transfer of vibration from the floor to the furniture, thereby adapting the casters for use upon beds used by those debilitated by acute illness or invalidism.

With these and other objects in view, which will readily appear as the nature of the invention is better understood, the same consists in certain novel features of construction and combination and arrangement of parts here-' inafter more fully described, defined in the appended claims, and illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a caster embodying-my invention. Fig. 2 is a section of the same.

Referring now more particularly to the drawings, the numerals 1 and 2 represent two spring metallic strips crossed to form an X- shaped resilient caster-frame, the ends of the strips forming a series of spring-arms 8, to each of which is swiveled a caster-Wheel 4:. The arms 3 have a downward inclination, while the central portions of the strips are flat and horizontal and are apertured for the passage of the stem 5, which has at its lower end a shoulder 6 and a reduced threaded stem 7 to receive a nut 8, which clamps said strips" connection with the accompanying drawings, it will be seen that a spring-frame is provided which adapts the caster to yield when passing over obstructions or irregularities of sur face, thus preventing the resultant jars or shocks from being transferred to the furniture; also, that when the casters are employed upon beds used by the sick or inva= lided the casters will take up the vibration produced by others walking over the floors, &c., and prevent the same from being transferred to the bed and disturbing the occupant;

Further advantages of the invention are that it prevents undue noise when the occupant of a bed turns therein, does not elevate the furniture to an objectionable height, and provides sufficient bearing-surface to prevent the tilting or turning over of an article of furniture while the same is being rolled across the door.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the prim ciple or sacrificing any of the advantages of this invention.

1. A caster comprising an X-shaped springframe the arms of which are free to vibrate and provided with caster-wheels at their free ends, substantially as specified.

2. In acaster, the combination of a pair of resilient metallic strips crossed to form an X shaped'frame, a stem connecting the strips at .the point of crossing, and caster-wheels mount ed upon the ends of the strips which form the radial arms of the frame, substantially in the manner set forth.

3. A caster comprising, in combination, an X-shaped frame formed of a pair of crossed spring-metal strips having an interlocking engagement at the point of crossing, the free ends of the strips forming independentlyyieldable radial arms, a caster-wheel mounted on each arm, a stem passing through the crossed portion of the strips, and means for clamping the stem and strips together, substantially as set forth.

In testimony whereof I have hereunto set my hand in presenceof two subscribing witnesses.
