DESK AND TABLE TOP.

Application filed May 8,

To @ZZ whom. it may concern:

Be it known that I, JAMES l/V. TUCKER, a citizen ot the United States, and a resident of Oak Park, Cook County, and State of Illinois, have invented certain new and use ful Improvemelits in Desk and Table Tops, of which the following is declared to be a i'ull, clear, and exact description.

This invention relates to desk and table tops, and more particularly to mats or cushioned border pieces, adapted to be interposed between the tops of desks or tables and plate glass tops. The object of the present invention is to provide a cushioned mat or border piece which will prevent the plate glass top from slipping on the desk in case ordinary force is applied to it, and also to present a neat and pleasingappearance to the desk top. To these ends the invention consists in the several novel features hereinafter fully set forth and claimed.

The invention is clearly illustrated in the drawing accompanying this specification in which;

Fig. l is a perspective view of a fragment of a desk and glass desk top illustrating one form of the present invention applied thereto Fig. 2 is a plan of a fragment of a. cushioned strip embodying one form of the invention; Fig. 3 is a central longitudinal section therethrough; Fig. 4L is a detail longitudinal section, upon a greatly enlarged scale, showing the parts before being assembled; Fig. 5 is an enlarged fragmental longitudinal section through fragments of a glass desk top, and desk with my cushioned strip interposed therebetween; Fig. 6 is an enlarged central, longitudinal fragmental section through av modified form of the invention; Fig. 7 is a plan of a second modification and Fig. 8 is a centra-l vertical section through a third modification.

Referring to said drawing and first to Figs. l to 5 inclusive; the reference character il, designates a fragment of a desk, table or like article of furniture, having a top a and B, designates a glass top supported thereon by a. mat or border C, embodying one form of the present invention. The mat is formed of strips of material cut into the right lengths and is placed adjacent the edges of the desk top 0..

In its preferred forni the'strip comprises a strip 10, of felt or felt like material, and friction members ll, secured to the strip in 1922. Serial No. 559,220.

any suitable manner and presenting on one or both sides of the strip a series of friction surfaces i2, that engage with the face of the' desk top or glass plate, which is contiguous with the friction surface 12, or with the contiguous faces of both desk top and glass plate.

The friction members ll, may take various forms, as for instance, they may comprise blocks of rubber or cork to obtain the necessary grip or frictional contact with the surface against which they contact. The strip l0 is formed with perforations 13 along its length to receive the blocks 11, and the latter may be held therein by friction against the sides of the perforations. They `are made slightly larger in diameter than the diameter of the perforations and when inserted thereinto, they bear tightly against the sides of the holes. When punched out of rubber strips, the blocks take` the shape shown, in exaggerated form in Fig. 4, their sides being concaved inwardly, and when inserted in the holes the larger end portions overhang the holes and further secure the blocks therein. This arrangement prevents accidental disconnection between the strip and blocks during shipment and during the handling of the strip.

The blocks are a` trifle longer than the thickness of the strip, in order that they will positively contact with the surfaces of the desk top or glass plate. When the glass plate is placed on a mat, constructed in accordance with the above description, the elastic or resilient blocks l1 are compressed slightly under the weight of the glass plate, until the latter rests upon the strip 10, and because of the frictional contact between the blocks and the desk top and glass plate, the latter is kept from sliding on, from, or being displaced on the desk by any ordinary force applied to it. The felt strip excludes dust from the space underneath the glass plate and prevents the accumulation of moisture on its under surface.

In the form of the invention illustrated in Fig. G a cylindrical block l1a of friction material, such as rubber or cork is shown, its ends protruding slightly beyond the faces of the strip 10a.

In Fig. 7 a felt or felt like washer 10b is shown in place of the strip, and the friction blocks lll are secured in said washer by friction as in the other forms. In Fig. S a

felt Washer 10C is shown, butin placevof the friction block, thin wafer like discs or washers 11c of rubber or other friction material, may be secured to one or both sides of the Washer to act as a grip or friction member to engage with the desk top or glass plate, or both. T his Wafer like form offriction? member may be used on the felt strip'in place of the blocks.

lf desired the friction members may be colored or `tinted to present tliesame color as the felt strip, or they may be given a distinctive color as desired.

The article is simple in construction, is inexpensive and effectively accomplishes the purpose for Which it is intended.

More or less variation of the exact details of construction is possible Without departingfrom the spirit of 'this invention; I desireytlierefore, not to limit myself to the exact form of the construction. shown and described, but intend, in the following)` claims, to point out all of the invention disclosed herein.

I claim as .new and desire to secure by Letters Patent:

l. A cushioned pad for desk tops comprising a body portion of felt or felt like material7 and a friction 'member secured thereto with a face exposed outside of the -face of the body portion and adapted to frictionally engage with the surface of an object placed against the adjacent face of the body portion.

2. A cushioned pad for desk tops-comprising a body portion of felt or felt like material, and a friction member secure-d therein and ht ving end portions projectingbeyond the faces of the body portion.

3. A cushioned pad for desk tops comprising a perforated body portion of felt or felt like material, and a friction block frictionally secured in said perforation.

A cushioned pad for desk tops comprising; a perforated body portion of felt or felt like material and a friction block having a concave side secured in the perforation with its end portions projecting beyond the faces of the body portion.

5. A cushioned pad for desk tops comprising a perforated strip of felt material and rubber blocks, secured in the perforatons of said strip.

6. A cushioned pad for desk tops comprising,` a perforated strip of felt material and rubber blocks having concaved sides secured in the perforations of the lstrip by friction, the end portions of the block projecting beyond the faces of the strip.
