' Filed Dec. 24. 1934 3mm GlennJ.d3arre?T WWW Patented Jan. 7, 1936 PATENT OFFICE SUPPORTING RACK Glenn J. Barrett, Grand Rapids, Mich., assignor to American Seating Company, Grand Rapids, Mich., a corporation of New Jersey Application December 24, 1934, Serial No. 759,037

2 Claims.

The instant invention relates to supporting racks and more particularly to folding racks especially adapted for attachment to an angularly disposed support.

The primary objects of the present invention are to provide a rack for supporting books, papers or the like which is adapted for attachment to an angularly disposed support such as a tiltable desk top; to provide such a rack which may be folded and concealed when not in use; to provide such a rack which is particularly well adapted for attachment to tiltable tops of school desks of the general character shown and described in my co-pending application for patent, Serial No. 759,038 filed Dec. 24, 1934.; and to provide such a rack which may be readily installed for use, a rack which is utilitarian in use, and a rack which is economical in manufacture.

An illustrative embodiment of the invention is shown in the accompanying drawing, wherein:

Figure 1 is a fragmentary front elevational view of an angularly disposed support such as a tiltable top of a school desk and showing the folding rack of the instant invention unfolded for use;

Figure 2 is a fragmentary side elevational view thereof showing in dotted lines the rack folded upwardly and rearwardly in its concealed position when not in use; 7 I

Figure 3 is an enlarged fragmentary end elevational view of the rack when in its upwardly and rearwardly folded and concealed position;

Figure 4 is a fragmentary sectional view of the rack on line 4- 4 of Figure 1 when the rack is in its upwardly and rearwardly folded position;

Figure 5 is an enlarged fragmentary end elevational view of the pivotally connected supporting arm for the rack;

Figure 6 is a fragmentary front elevational view of that part of the structure which is shown in Figure 5;

Figure 7 is a sectional view on lines 'I-'I of Figures 2 and 8;

Figure 8 is an enlarged fragmentary end elevational view of the rack and its pivotal connection with its supporting arm when the rack is in unfolded position for use;

Figure 9 is a fragmentary front elevational view of that part of the structure which is shown in Figure 8; and

Figure 10 is a sectional view on line Ill-l0 of Figures 2 and 8.

Referring to the drawing in which like parts of the structure shown are designated by the same numerals in the several views, an angularly disposed support it such as a tiltable top of a school desk of the general character shown in my co -pending application for Letters Patent, Serial No. 759,038, filed Dec. 24, 1934, has its rear surface It provided with a trough l2 adjacent its upper marginal edge.

A pair of brackets l3, preferably of metal, each having a flanged lip Hi, are respectively secured to the rear surface of the support l0 adjacent the marginal ends 15, H5 thereof and intermediate their lengths. A pair of arms ll, [8, likewise preferably of metal, are respectively pivotally secured to the lips M of the brackets l3 as by a pintle l9 and to the free ends of each arm are pivotally secured a member 20 having an inwardly turned portion 2|.

A cross member 22 of metal or other suitable material of sufiicient width to form a supporting rack for books, papers and the like is rigidly secured to the oppositely disposed inwardly turned portions 2i of the pivoted members 20 as best shown in Figures 8, 9 and 10.

In operation, it will be assumed that the cross member 22 is in the unfolded position shown in full lines in Figures 1 and 2. In this position, the cross member is adapted for use as a supporting rack for books, papers and the like. When this supporting rack is no longer desired for use, the arms ll, I3 may be folded upwardly and parallel with the ends l5, [6 of the support It] and the cross member 22 thereafter folded downwardly behind the upper edge of the support and into the trough, all as best shown in Figures 3 and 4 and as is indicated by dotted lines in Figure 2.

It will thus be seen that the supporting rack for books, papers and the like herein shown and described is particularly well adapted for attachment to tiltable tops of the school desk type and when attached to a tiltable top of the character herein shown and described, the rack may be folded upwardly and thereafter downwardly to a concealed position when not desired for use.

While but one specific embodiment of this invention has been herein shown and described, it will be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims.

I claim:

1. A supporting rack adapted for attachment to an angularly disposed support comprising a pair of arms pivotally connected at one end in termediate the ends of the support and a cross member pivotally connected adjacent the free ally connected at one end intermediate the ends of the support and a cross member pivotally connected adjacent the free ends of the arms whereby the arms may be folded upwardly parallel With the ends of the support and the cross member thereafter folded downwardly behind the upper edge of the support and into the trough.
