My invention is not limited to the particular constructional details herein shown and described, for it is evident the same may be varied within the spirit and scope of my invention, as herein set forth.

Having described one embodiment of my invention, and without limiting myself as to details, what I claim, and desire to secure by Letters Patent, is

1. In a drawer-support, the combination of suitable runs, drawer-supporting extensionslides, the drawer provided with tracks fixed to the drawer and extending laterally over the slides, antifriction-balls interposed between the slides and tracks, and other and independent antifriction-balls interposed between said slides and runs, the said balls being confined between the ends of the runs, slides and tracks respectively in partly-circular grooves sunk to a greater depth than half the diameter of the balls to prevent the escape of the balls, the said balls having the capacity of distributing themselves in the direction of the length of said parts, substantially as described.

2. In a drawer-support, the combination with parallel runs, of the extension-slides arranged between the same, the drawer provided with laterally-extended tracks resting upon and supported by said slides, antifriction devices at the under sides of said slides and between the same and the adjacent runs, and a plurality of series of antifriction devices at the upper sides of each extension-slide and between the latter and the said drawer-tracks and independent of the antifriction devices at the under sides of the said slides, to operate substantially as described.

3. The combination with the runs, of the extension-slides, provided at their rear ends with the upwardly-extended projections b and at their lower sides resting upon the antifriction-balls arranged in grooves in the runs beneath said slides, the drawer provided with laterally-extended tracks 2, independent series of antifriction-balls arranged in a groove at the upper edge of each extension-slide, and the depending projections (1 d", on each of the said drawer-tracks, the latter projections separating the series of antifriction-balls at the upper side of each slide, substantially as described.

4. In a drawer-support, an inclosing case, runs therein, the drawer, and side tracks applied to such drawer, the extension-slides arranged above the lower runs and having slight grooves or depressions in their under sides, the lower runs being supplied with partlycircular grooves in their upper faces sunk to a greater depth than half the diameter of the balls to prevent the escape of the balls, anti friction-balls arranged in such grooves and next the bottom edges of the slides and fitted to the said slight grooves or depressions in the said bottom edges of the slides, and other and independent antifriction-balls arranged in partly-circular grooves in the upper edges of the slides and in slight grooves or depressions in the under sides of the side tracks, the several series of antifriction-balls having the capacity of distributing themselves in their respective grooves in the direction of the length of the parts, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JEREMIAH CURTIS KIMBALL.
