BULLETIN BOARD AND THE LIKE.

Application filed June 23, 1923. Serial No. 843,305.

To all whom it may concern:

Be it known that I, GEORGE W. BROOKS, a citizen of the United States, residing at Topeka, in the county of Shawnee and State 5 of Kansas, have invented certain new and useful Improvements in Bulletin Boards and the like, of which the following is a specification.

This invention relates to certain new and useful improvements in drawing-boards, display-boards, bulletin-boards and the like, I and it has for its objects among others to provide a simple and cheap, yet eliicient and durable article of this character which shall be practically fire-proof in its nature and which will retain its shape under all condiions, not being subject to shrinkage or warpage and not bcin affected by dampness.

It has for a urther object to provide a fire-proof piece of furniture of this general character which can be used where a permanent surface is required for holdin blotters, tracings, notices, bulletins or the ike, or in any place where an even and level surface is required. A further object is to provide a cushion surface of such a nature as will hold the tacks until it is desired to remove them and when removed the holes or perforations will readily automatically close up. The surso faceis made of a cushion composition 01 felt, cork, sawdust, or similar material ground, and the particles thereof held together by rubber or elastic cement. The object of this surface covering is to form a as cushion or elastic bed which will be binding enough to hold the tacks and prevent them from rusting and yet permit them to be easily removed when it is desired to apply any surface, such as paper or the like, or to at? remove the same from the cushion surface. The cushion surface can be repeatedly used as by its elastic quality it will quickly close up the opemngs and will not waste or deteriorate as does the solid or nonelastic or $5 brittle surface. The metal backing to which the composition is firmly cemented forms a ermanent and substantial backing for the goardwhich is not subject to shrinkage or Warping or afi'ected by dampness. Furthermore, boards constructed in accordance with my present invention will not shrink or buckle when in stock re oratory to being installed and will not no le or War when installed on walls The metal asking and the firm cementing of the composition thereto mostefi'ectually prevent this.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawing, which, with the numerals of reference marked thereon, form a part of this specification, and in which- Figure l is a face view of a drawing or displayboard constructed in accordance with my present invention.

Figure 2 is a section on the line 2'-2 of Figure 1. looking in the direction of the arrows. I

Figure 3 is a face view showing the board a with a plain molding or backing.

Figure 4 is a section on the line 4-4 of Figure 3, looking in the direction of the arrows. 7

Like numerals of reference indicate like parts throughout the diii'erent views.

In carr ing out my invention, I employ a metal bac ing 1 of the requisite dimensions and upon this I cement a covering surface 2 which may be of a material well suited to the purpose, such, for instance, as a composition of cork, felt, sawdust or similar material ground and thoroughly mixed with rubber or elastic or analogous cement by which the .35

articles are held together, the composition eing of such a nature as to readily yield upon the insertion of tacks or the like thereinto, but to firml hold the tacks in place when once insert-e and still permit of ready 99 removal when desired, and when the tacks are removed the holes or perforations made thereby will be quickly automatically closed up by reasonof the elastic nature of the covering or be This bed may be of any thickness best suited to the purpose for which the board is to be used, and this surface may be enclosed within or embraced by a molding which may be of an desired character. In Figures 1 100 and 2 l ave shown this moldin as of an ornamental nature. It may be 0% any suit-- able material, such as fibre or metah'a'nd in Figures 1 and 2 this molding or enclosin member 3 is composed of a. hollow meta member 4 having the depression 5 in its face in which are located the securing means 6, the heads of which are below the top surface of the board and, in the present instance, this moldin strip is shown as enclosing the member 7 W. icli me he of any suitable material, the under edges of the metalheing 6 intnrned opposite sides, as shown in Fig ure 2,'to form an inturned flange 8 at each edge which engages in the filling or member 7, as shown, and these inturned portions or flanges 8 hear a ainst the metallic backing 1. This form. of binding or border is shown as mitered at the corners, although this is not essential.

As shown in Figure 2, the cushion coverfing or surface 2 projects slightly above the 5. outer face of the molding so that the molding will not interfere with the free use of the hands in applying the bulletins and to allow the bulletin etc. to stand out in bold relief on the cushion.

The board in some cases may he used Without an enclosing border or frame, as shown in Figures 3 and 4:, wherein the covering surface 9-is mounted upon the metal hack ing 10, the latter extended beyond the cover Linlgto form the surrounding border or the e 11. I

all forms the covering surface is firmly panama to the metallic hacking and is "protectedhy the latter so that the board does notwerp, buckle or shrink and constitnte menses an e'llicient metal furniture equipment where an article of this nature that is absolutely fireproof is desired.

Modifications in details may be resorted to Without departing from the spirit of the invention or sacrificing any of its advantages. For instance, as shown in Figure 4 the border 11 may be turned up at right anglee as indicated by dotted lines to form a border for the cushion cover, or it may lie extended as seen in Figure 3 through which portion nails or the like may he passed to secure it in place. This portion 11 may be ornamented in any suitable Way to give it a finished appearance.

What is claimed as new is 1. A bulletin or display board composed of a fireproof non-warpable backing, a cushion of yielding material firmly cement ed thereto, and a border around the cushion ends engaging the edges of
