Application led April 3, 1911. Serial No. 618,746.

To all whom it may concern:

Be it known that I, MYRON Cossnr, a citizen of the United States, and resident of the borough of Brooklyn, county vof Kings, and State of New York, have invented certain new and useful Improvements in Drawer-Slides, of which the following is a specification. Y

It has been my purpose to improve t-he construction of the means used for guiding and supporting drawers and similar devices so that they may easily and accurately slide into place.

One of the objects of the invention is to provide a drawer with anti-friction sliding means which .will permit perfectly free movement longitudinally, but which will prevent movement in other directions which mi ht result in binding.

other object has been to produce the anti-friction slide in such form that it can be easily and cheaply made in light form but of sucient strength to stand the strains of practical use.

The novel features of the invention will be apparent from the following description,

taken in connection with the accompanying drawings. v

In the drawings Figure 1 is a cross section of avportion of the drawer and casing having the preferred form of my drawer slide applied thereto; Fig. 2 is a detail perspective view of the ball spacing and retaining means; Fig. 3 is a side view of a portion of the slide; Fig. 4 is a side view of the drawer and casing having my preferred form applied thereto, the drawer being pulled open; Fig. 5 is an end view of the preferred form of my slide showing the limiting stops; and Fig. 6 is a side view of t-he track members showing the limiting stops in operation. Fig. 7 is a sectionalview of a i modified arrangement of the slide.

In Fig. l I have shown a casingf 1, which vma be a deskor similar article of furniture,

which is provided with an ordinary drawer 2. These parts are usually made of wood and the side wall of the drawer is spaced from the corresponding side wall of the casing sufficiently to receive my improved slide. In the preferred form, my slide is made up of two .track members formed from sheet metal, preferably'drawn steel. As will be Seen by reference to Fig. 1, the track member 3 is .made substantially U-shaped in cross sectlon and it extends longitudinally of the drawer casing at the side from thc- The free edges of the movable track are Patented Nov. 2e, 1912.-

bent or rolled outwardly so as to leave inwardly, facing groovesv 8 and 9 which register with the grooves 5 and 6. The outward bends leave shoulders 10 and 11 on the interior of the movable tracks 7, and a mov- -able ball retainer 12 preferably made of steel fits loosely between the 'shoulders 10 and 11 and slides freely longitudinally within the movable track 7. This retainer is also U-shaped in cross section fitting over 'and embracing the fixed track 3 loosely, and

rovided with holes 13, Fig. 3 to receive the alls 14 moving in the registering grooves of the two tracks. This retainer serves to properly space the balls and to hold them in position, and it will be understood that it moves along the track with the balls. At the ends of the fixed track 3, I place the strengthening filler blocks 15, these blocks fitting between the sideflanges and being held in place by t-he screws 16. A pin 17 projects from the face of this blockalmost to the rear wall of the movable track 7 standing in the path of the spacer 12. This pin 17 may be in the form of a screw passed through the fixed track 3, and the block 15. At each end of the movable track 7 a pin 18 is placed 'projecting inward in the path of the retainer 12. These pins 17 and 18 serve as stops to limit the movementof the track 7 onthe track 3, because when the pin 17 at the front end of the fixed track 3 is struck by the retainer 12, it will prevent any further forward movement of that retainer and its balls and when the -pin 18, Fig. 6,

-at the rear end of the movable track 7 Vstrikes the other-end of the retainer 12 the movable track'7 cannot move outward ,any

farther. While I have shown the slide only on one side of the dra-wer it will be understood that a duplicate of this is used on the other side of the drawer, and it will be observed by reference to Fig. 1 that the drawer is supported from the slide by means of a longitudinal strip 19 which may be made of wood held in place by the screws 20. This strip or rail simply rests by gravity on top of the straight upper surface of the movable track 7 and the frictional engagement makes t-he movable track move forward when the drawer is pulled out, but it will be observed that when the track has moved its full limit, and the stops come into operation, it is still possible to move the drawer making the strip or rail 19 slide on the movable track 7, and thus the drawer can be entirely removed from the casing leaving the anti-friction drawer slides 'still in position in the casing. The drawer preferably lits closely against the inner straight vertical face of the movable track 7 so that movement is longitudinal.

vent binding and will make the drawer there will be no play or lost motionand the connection betweenthe movable track and fixed track is such that the only relative This will premove easily and smoothly into either open or closed position.

It will be observed that the form of slide shown in Fig. 1 can be easily and cheaply made of drawn steel which will be \com paratively light and which will at the same time have the requisite strength to stand'all the strains of practical use, and it willl further be observed that by the construction described the drawer will work easily on the anti-friction bearings yunder V all ordinary operations and that the drawer can be absolutely removed from the casing without disi turbing in any way the anti-friction slide.

In Fig. 7 I have shownV a modified arrangement in which the parts occupy different relative positions but the structure of the two sliding members and the structure of the ball retainers correspond with that described in connection with Fig. 1. In this modified form the outer slide 21 of sheet metal is secured to the casing 1 by screws 22 and the inner slide member 23 is placed with the open side of the U-shaped cross section facing in the same direction as the member 21 so as to form practically a slot in which slidably and loosely lits the strip 24 secured to the drawer 2. In this instance the drawer is supported through the strip 24 vfrom the member 23 and it is in turn'supported by the balls .from the fixed member 21 and it will be understood that the strip 24 can slide out beyond the end of the member '23 so that the drawer can be entirely removed just as in the structure shown in Fig. 1.

While I have disclosed avpreferred embodiment of my invention it will be understood that the invention its broader laspect is not limited to the detailsof construction described and shown. Having thus described the invention, what is claimed is: 1. The combination with a drawer, of a casing for said drawer, tracks supporting said drawer at the sides having separated grooves facing each other and extending in the direction of movement of said drawer, tracks secured to said casing and provided with oppositely facing grooves registering with the irst mentioned grooves, the tracks on the casing and tracks supporting thel drawer telescoping one into another, anti- 80 friction balls in each pair of grooves locking the parts against any movement except y longitudinal, and integral means engaging the balls in both grooves to hold the same in spaced relation to each other and allowing the simultaneous movement of the balls ybut holding the same against independent movement.

2. The combination with a drawer, of a casing therefor, a track secured to said casing having oppositely facing longitudinalgrooves, a second track movable on the first having grooves facing and registering with said first mentioned grooves, anti-friction balls in said grooves locking said tracks against any relative movement except longitudinal, one piece spacing means for said balls in both grooves to allowsimultaneous movement of the balls but to hold the same against independent movement, and said drawer being provided with a part slidably resting von sald movable track to support said drawer.

3. The combination with a drawer, of a casing therefor, a track secured to said casing at each side having oppositely facing longitudinal grooves, a second track movable upon each of the first mentioned tracks having grooves facing and registering with said rst mentioned grooves, anti-friction 110 balls in saidA grooves-` loclng said tracks against any relative movement except longitudinal, a spacing means for the balls in both grooves to permit simultaneous movement of said' balls but to hold the same 115 against independent movement, and rails on the sides of said drawer frictionallyl resting on said movable tracks whereby said drawer and tracks will normally move together and said drawer may 'slide on the 120 track when said track has reached the limit of its movement.
