3- Claims. 1

The present invention relates to novel, useful and improved means whereby slidable drawers in case goods may be more satisfactorily installed and caused to operate easily and a principal object of the invention is to structurally, functionally and otherwise improve upon prior art constructions in this field of: endeavor.

Commonly used case goods and complemental drawer constructions are considered to be highly objectionable due to factors which promote undesirable noises, clatter arising from mismatched impacting surfaces, and sticking.

Take, for example, the noise factor existing in certain standard methods of manufacture and assembly. In a so-called better construction, it is common practice to employ a rigid thumb tack, or equivalent glide, and this is fastened to the front side of the dust panel on which the bottom surfaces of the drawer sides run. As the metal glide is driven solidly into the wood, it obviously acts as a transmitter of sound, usually magnifying it as the drawer surface moves across same. When no glide is the action is rough and crude and even noisier, since wood running against wood generates friction and accompanying noises.

In other constructions, in order to compensate for swelling of drawer parts, the drawer frame is usually made smaller than the front opening in the drawer compartment of the case or other relatively stationary support. Consequently, when the drawer is drawn out to a position. beyond the central balancing point, the top portions'of the inward members of the drawer frame tilt up againstthe drawer guides, producing an objectionable clattering sound and, conversely, when the drawer is pushed back into-its receiver or compertinent,v it then falls to and resumes. its original position, repeating the hammerlike clatter.

If predetermined clearances between surfaces are taken into account and reduced to a minimum, in order to minimize the stated clattering, which is now being done. in building, precisionmade case goods, an additional risk is run because the drawers swell, warp, bind and hang. I'his results in sticking, which is equally as objectionable as the noisy clatter above referred to.

a result of studied consideration of the objectionable factors touched upon, I have evolved and producedfloating and cushioned drawer mounting means, characterized essentially by novel self-adapting glides, and in so doing have provided a construction which has substantially eliminated screeching noises, banging clatter, and nerve-racking sticking.-

In carrying out my aims, I provide an improved 2 drawer glide which is unique in that it embodies a concave-convex glide or button, a rigidly attached nail, and a resilient washer surrounding the nail and fitting and held in the concave or dished side of said button.

More specifically, novelty has to do with the use of a plurality of properly positioned. glides, two of which are attached to the cabinet or case and four of which are attached to the sliding drawer frame, these being coactable with nail holes which are oversize in respect to the nail and of lengths greater than the length of the nail, whereby to permit the desired independent expansibl'e and contractible and self-levelling action of the respective glides and promoting the desired floating and cushioning results.

Other objects and advantages will become more readily apparent from the following description and the accompanying illustrative drawings.

In the accompanying sheet of drawings, wherein like numerals are employed to designate like parts throughout the views:

Figure 1 is a view in section and elevation showing a cabinet, of any suitable type, upper and lower drawers fitting slidably into the compartments provided therefor, and my improved equipment, the novel glides properly installed.

Figure 2 is an enlarged fragmentary view showing one of the glides and the manner of installation of same.

Figure 3' is a perspective view of one of the imr proved glid'es. I

In Fig. 1, the case goods, which we may identify either as a relatively fixed support or cabinet, is denoted, generally visualized, by the numeral- 5. is shown as constructed to accommodate an upper slidable drawer 6 and a lower slidab'le drawer T. The drawer frame, in each: instance, is denoted by the numeral. 8' and the closing panel or dust guard by the numeral 9. The cabinetis provided with compartments of customary form and looking at the upper compartment, this is characterized by a divider or horizontal partition l0 forming the bottom of the compartmentand guide railsl l in the ceiling. of the compartment. Fig. I shows one drawer closed and one drawer partly open and its primary purpose is to illustrate the construction, arrangement: and functioning of parts. In the lower compartment II for drawer 1, the bottom l3 constitutes the: slideway and corresponds to the partition Hi and the guide rails are denoted by the numerals H and correspond to the aforementioned guide rails or runners ll.

Each glide is the same in construction and each comprises a concavo convexz anti-friction head of suitable strength and size provided with an integral centrally situated pin or nail IS. The cushioning washer, which is of resilient rubber or the like, is denoted by the numeral I1 and this surrounds the shank of the nail and is fitted and held in the concaved side of the head which then constitutes a cup or receiver therefor. It is desirable to fashion the marginal portion of the head into a clenching bead or lip l8 to facilitate maintaining the cushioning washer in place. In fact, in some instances, it is desirable to attach and bind the washer to the head by way of an adhesive compound (not shown).

Wherever the glider is installed, a nail-hole is provided and this is denoted by the numeral [9 (see Fig. 2 for example) and this hole is of a greater cross-sectional diameter than the crosssection of the nail. That is to say, the nail-hole is oversize and, in addition, is longer than the nail and thus permits the nail to have the desired "play by rocking from side-to-side and sliding at right angles to the surface with which it coacts.

To install a glide, use an oversize hole I!) as a guide for the nail or pin [6, making sure latter does not touch the bottom of hole and is free to move in a vertical direction. Cement cushion ll of glide in position with a resilient cement that will not congeal or harden, leaving glide free to move up and down as load is applied or taken off.

In practice, I install two cushioned drawer glides in front side of case dividers, one under each side of drawer frame and on which latter may then ride freely in and out. Two cushioned drawer glides 2| are mounted on drawer, top back side on which back of drawer glides. Two drawer glides 22 are mounted on drawer frame on the bottom back side which serve to carry load at top of drawer as drawer is pulled from case.

As drawer floats on four cushioned drawer glides 20 and 22, sound travel between drawer and case is practically eliminated as glides are not securely fastened to either drawer or case, each being self-levelling and floating on its expansible and contractible cushion.

Two glides 2| keep the top of drawer from clattering against the top guides when said drawer is pulled out as cushioned glides 2| compress when load is transferred to them. In returning the drawer glides 22 repeat the action upon absorbing load, again eliminating clatter.

Drawers can be given considerable clearance as the clattering is eliminated by using cushioned glides, top and bottom. Even though the slides 22 and 2| are purposely fitted with little clearances, a drawer will not stick because the cushioned and self-adjusting activities of said glides will absorb swelling of drawer sides, allowing freedom of action of the drawer.

Although I have referred to the cushioned glides in a collective and assembled sense, it will be understood that novelty is thought to reside in each glide per se as detailed in Fig. 3 of the drawing and that additional novelty has to do with the installation in a supporting member of a single guide as shown, for instance, in Fig. 2.

In view of the foregoing description taken in conjunction with the accompanying drawings, it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even 4 though there is herein shown and described a preferred embodiment of the invention, the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and within the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. In combination, a cabinet embodying an enclosed space defining an open ended sliding drawer compartment havin a firm horizontal bottom and at least one fixed horizontal drawer rail, 3. drawer telescoping and slidably mounted in said compartment and having a member thereof in spaced parallel relation to said bottom, the bottom having a vertical pin accommodation hole, and at least one drawer cushioning glide embodying a rigid concavo-convex anti-friction head having its convex surface in supporting contact with said member, a rigid pin fixed centrally and rigidly to the concave side of said head and extending therefrom and projecting slidably and loosely into said pin accommodation hole, and a responsively squeezable, self-adjusting cushioning washer encircling said pin and abutting and operatively cooperating with the concave side of said head and attached directly to said bottom surface by an adhesive, said washer being made of elastic rubber which increases and diminishes in size readily in response to varying pressure demands.

2. In combination, a cabinet embodying an enclosed space defining an open ended drawer compartment having fixed guide means including a horizontal member, a drawer telescoping and slidably mounted in said compartment and having a vertical member at right angles to said horizontal member, said vertical member having a vertical pin hole, and a drawer cushioning glide having a rigid smooth anti-friction head interposed between said members and having free sliding contact with said horizontal member, a rigid pin fixed centrally and rigidly to one side of said head and extending therefrom and fitting slidably and loosely into said pin hole, and a responsively squeezable, self-adjusting cushioning washer encircling said pin, interposed between said head and vertical drawer member and spacing the head from said drawer member and attached to said drawer member by an adhesive, said washer being made of elastic rubber which readily increases and diminishes in size in response to varying pressure demands.

3. The structure defined in claim 2, wherein said adhesive is of such character that the bond between the washer and drawer member will retain itself against a horizontal force exerted against the washer during drawer movements.
