` `FRQuvIE CONSTRUCTION Filed Feb. 3, 1931 BULLETIN Patented July 10, 1934 FRAME CONSTRUCTION Charlesr M. Dill, Manoa., Pa.
Application February 3,
6 Claims.
My invention relates to building construction, and the object of my invention is to provide a neat, substantial and ornamental frame for enclosing card panels, bulletin boards, blackboards, and the like, more particularly designed for use in class rooms of school buildings; such frame forming the final iinish between the black-board or panel structure and the wall receiving the same, and closing the gap between the wall and such board or boards.
A furtherobject of my invention is to place the black-board, panels, etc., and/or the supports therefor, in a recess in the wall, and to carry edge portions of such frame intovthe recess past the edge of the plaster or other wall-nish at the margin cf `such recess. Since the black-boards, panels, etc., are placed entirely within the recess left in the plaster `in the use of my invention, it is not necessary to wait until the plaster dries 'out before erecting the black-boards, panels,l etc.,` thus saving material time in the constructionof the building. ,Y
These and other features of my inventionare more fully described hereinafter; reference being had to the accompanying drawing, in which:`
Figure 1 is a front elevation, partly broken away, of my improved construction illustrating a card panel, bulletin board, and black-board combination enclosed by the frame structure forming the subject of my invention.
Fig. 2is an enlarged sectional View taken on the line IIL-II, Fig. 1; illustrating the chalk tray portion of the black-board and showing also a sectional view of the frame disposed adjacent there- Fig. 3 is a-fragxnentary plan view of an-end portion of the chalk tray showing also a sectional view of the frame at the side of the black-board. Fig. 4 is a cross-sectional view of a portion of 40 the frame taken on the line IV--IV, Fig. 1, and
Fig. 5 is a sectional View illustrating a modilied form of chalk tray construction.
The usual practice in placing black-boards,.
, bulletin boards, card panels and/or the like upon the walls of class rooms, is to mount them upon such wall and to enclose them in a heavy wooden frame, which frame is of a size that materially reduces the area of the black-board, panel and/or the like.
In carrying out my invention, the wall 1 is recessed at 2 for the reception of supports 3 for the black-board, panel boards, bulletin boards, etc., indicated at 4, 5 and 6 respectively. The recess .receiving the combined board structure is slightly oversize in order that the board and panel struc- 1931, Serial No. 513,191 (Cl. 35-15) ture may be readily set in place, even before the plaster or other wall nishis dry; the gap at the bottom being indicated at a, in Fig. V2; the gap at the side beingindicated at b, Fig. 3, and a gap that may exist between separate sections ofthe boards or panels, is indicated at c in Fig. 4.
The frame, preferably of metal, designed to enclose the several slabs or surfaces making up the combined structure, is indicated generally at 10. This frame comprises a continuous outer or marginal portion 10a, and division sections 105 disposed between and/or covering the joints between the several panels and/or board sections, and connected to said portion 10a. i
The outer or marginal portion 10a ofthe frame 70 comprises a flange portion A engaging'Y the surface of the several boards or panels, with a boxlike portion B in the form of a raised rim `constituting the actual margin of the frame, and a flange C, continuous with the box-like portion B, and extending into the gap which lies between the board or panel structure and the edges of the wall recess receiving the same. The frame sections are adjusted to the boards or panels when being mounted so that this ilange C may be placed in such position as to closely engage the plaster or other Wall nish at the edge of the opening or wall recess and thereby provide a definite closure for the gap that would otherwise exist between the board or panel structure and wall. The portions A and B of the frame section are of ample extent to cover the edge of the board or` panel and permit positioning so that the flange portion C may be spaced away from the board to the desired extent and engage the plaster or other wall edge. The frame may be secured in place by screws 11 which may pass through the flange portion "A of the same and through the blackboard or panel and enter one of the supporting members 3. v
The secondary or inner frame members 10b cover the joints between the respective board and panel sections and are preferably of the crosssectional contour indicated in Fig. 4; comprising a box-like portion B and side flange portions A integral therewith and in parallel relation. The several sections making up the frame are neatly tted together with miter joints at the several meeting points, as clearly indicated in Fig. 1, and these joints may be made permanent by welding, brazing, or the like.
A chalk tray 12, preferably of metal, is associated with the frame enclosing the board and panel structure, and this may be of the cross-sectional contour illustrated in Fig. 2. Such tray underlies the board and panel structure, and the lower portion of the marginal frame a is so arranged that the flanged portion A of the same overlies the top of the rear portion of such tray;
which rear portion may overlie and be secured to a support 3a carried by the wall 1 below the board and panel structure. The chalk tray may have end walls 12a designed to prevent the chalk and erasers usually carried thereby dropping off. In Fig. 5 I have illustrated a modified form of chalk tray, in which the tray portion is entirely below the board and panel structure and extends rearwardly beneath the same; such arrangement cutting down the amount of projection into the room. In this form of arrangement, the rear portion of the tray includes a flange 12b which may be secured to the wall 1 by screws. In Veach instance, the apron of the chalk tray maybe sef cured to backing members 3 by suitable screws.
While in most instances the plaster or'other material which may be used as a wall finish at the edges ofthe recess receiving the board and panel structure will present sharp'corners against which the flange C of the frame sections may abut, substantially at right angles to the surface of such plaster, I may employ a plaster terminal of the type illustrated in the patent of Baum, No. 1,727,- 953, at the several edges of such recess.
While I have shown a combination black-board and panel structure, it will be understood that my improved frame construction may be employed with one or more black-boards alone, or one or more panelsalone, disposed. in a recess of thewall upon which it is mounted, without departing from my invention.
` or the chalk or other dust wiped from the blackboards and/or panels, staining the adjacent plaster or other wall finish. At the same time such frame may be readily wiped or polished without marring or smudging the adjacent wall surface.
While I have referred to the use of a metal frame, it will be understood that I may employ forms of molded material, bakelite, kor various forms of synthetic plastic bodies, without departing from my invention.
Iclaim:
