DRAWER-GUIDE.'

SPEGFCATION forming part of Letters Patent No. 742,132, dated October 20, 1903.

Application filed January Z6. 1903.` Serial No. 140,475. (No model.)

To all whom, t mayV concern:

Be it known that I, JOHN SCHAAD, a citizen of the United States, residing at Knoxville, in the county of Knox and State of Tennessee, have invented a new and useful Improvement in Drawer-Guides,of which the following is a specification, reference being had to the accompanying drawings.

-The object of myimprovement is to provide the drawers of bureaus, desks, and similar pieces of furniture with antifriction devices for preventing the binding of the drawers while being opened or closed. It is the purpose of said devices to prevent the drawer from turning laterally'out of parallel with the space in which the drawerfnormally rests and also to prevent the rear upper portion from binding when the drawer has been par-` tially opened and the front part of the drawer bears downward and the rear portion is raised, the drawer resting pivotally upon the front rail.

My invention is specially designed to aiford simple and economical means for forming said guides. i

The present invention is animprovement upon the construction described in Letters Patent of the United States No. 710,523, granted to me October 7, 1902.

In the accompanying drawings, Figure 1 is a vertical transverse section through a drawer embodying my improvement. Fig. 2 is an enlarged fragmentary rear elevation of the drawer shown in Fig. 1. Fig.` 3 is a section on the line 33 of Fig. 2. Fig. 4 is a rear elevation,.and Fig. 5 is a plan, of a modification in which the guide-rollers are secured toa block and the block is secured to the rear face of the rear wall of the drawer.

Referring first to Figs. 1, 2, and 3, A is the drawer. B B are the horizontal front rails located above and below the drawer-com partment. C is one-of the horizontal end rails upon which the drawer rests. D D are back rails, and D D are panels filling the-spaces between the back rails D. Said rails D and panels D together form the rear wall of the drawer-compartment. Obviously said rear wall may be formed in any suitable manner, or it may be incomplete or altogether omitted, according to the nature of the article of furniture.

A is the rear wall of the drawer. v The upper edge of this is preferably lower than the upper edge of the front wall A2. At its mid- .dle the rear wall A' has a transverse vertical recess or notch a cut into its u credere of suitable width and depth to receive the vertical roller E, which is suitably journaled, as

upper face of the rear wall of the drawer and against or nearly against the lower face of the guide-rail F. Located directly over said rollerYE is a horizontal guide-rail F, secured in any suitable manner, as by the attachment of its ends to the adjacent front and back rails. The lower edge of said guide-rail a1- most touches said roller and is adapted to receive contact from the latter when the drawer is being pulled out or tilted upward at the rear.

On each side of the guide-rail Fa horizontal roller G is mounted upon the upper edge of the rear wall of the drawer, a suitable vertical post or axle G extending centrally through each of said rollers. Said rollers are placed so near the adjacent faces of said guide-rail as to cause engagement between Said rollers and said faces when the drawer shifts laterally to a slight extent. Thus the usual binding of the drawer at its ends when moved out of parallel by moving oneend in or out in advance of the other end is prevented. The lateral Inovementof the drawer is prevented by said rollers, and, furthermore, binding on the guide-railis prevented by the ready rotation of V the roller G, which, is brought into contact with said guide-rail. The attachment of said guide-rail is easily made by cutting it of proper length to extend across the space between-.the front and back rails. rollers is simply and economically accomplished. The notch a may be readily cut The attachment of said antifrictionout of one board or simultaneously cut out of a number of boards clamped together.

By placing the axle E against or into the vertical face of the rear wall of the drawer instead of into recesses cut down through the upper face of the drawer, as described in my said Letters Patent, the labor is lessened and the entire upper face of the drawer-wall is left clear and free for the application of the horizontal rollers G, and the axle E may be made of any desired length without intertering with the vertical posts or axles G, which support the two horizontal rollers G, and it is unnecessary to lill recesses in the upper face of the rear .Wall of the drawer preparatory to attaching therollers G. It will be observed that under this construction the guide-rail F maybe narrowed as much as desired and the rollers G brought correspondingly near to each other.

In Figs. 4 and 5 a block A3 is secured to the rear face ot the rear wall A oi"4 the drawer, the upper edge of said block being iiush with the upper edge of said wall, and the rollers E and G are secured to said block precisely as they are secured directly to said wall in Figs. l, 2, and 3. Said block A3 may be secured to said wall by screws a3 or in any suitable manner. These blocks A3 may be made separately from the drawers and have the rollers attached by theuse of special machines and applied to the drawers after the latter are otherwise completed. The block A3 is to be regarded as a part of the Wall A' of the drawer after said block has been secured to said wall. Said blocks may be ot Wood or metal and may be varied in form.

I claim as my invention- I. The combination of a drawer, the rear wall of which has a transverse notch in its upper portion, a vertical roller located in said notch and having its axle secured to one of the vertical faces of said Wall, two horizontal rollers secured to the upper face of said wall, one at either side of said vertical roller, and a guide-rail.

2. The combination ot' a drawer comprising a block applied to the rear wall of said drawer so as to constitute a part of said wall, said block having a transverse notch in its upper portion, a vertical roller located in said notch and having its axle secured to one of the vertical faces of said block at a proper elevation to bring the upper portion of said roller approximately into line with the upper face of said block, two horizontal rollers secured to the upper face of said wall, one at either side of said vertical roller, and a guide-rail.

In testimony whereof I have signed my name, in presence of two witnesses, this 12th day of January,` 1903.

JOHN SCIIAAD.
