Patented Oct. 24, 1939 PATENT OFFICE CHAIR TRAY John J. Brazell, Baldwinsville, Mass, assignor to E. L. Thompson Chair Corporation, Baldwinsville, Mass, a corporation of Massachusetts Application September 25, 1937, Serial No. 165,727

2 Claims.

This invention relates to children's high chairs and particularly to trays for use with such chairs.

It is the general object of my invention to provide improved means for supporting such trays and for preventing displacement or breakage of the supporting parts.

A further object is to provide a combination of tray and support which will be pleasing in appearance and reliable and effective in use.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of the invention is shown in the drawing, in which Fig. 1 is a plan view of a portion of a tray and support embodying my improvements;

Fig. 2 is a partial side elevation, looking in the direction of the arrow 2 in Fig. 1;

Fig, 3 is a detail sectional side elevation, taken along the line 3-3 in Fig. 1; and

Fig. 4 is a perspective view of a metal clip to be described.

Referring to the drawing, I have shown a portion of a tray. l which is preferably formed of wood and which has a substantial thickness of stock at its rear corner portions. The tray II] is provided with supporting arms I I, which may be pivotally secured to the back frame of a chair in any convenient manner, as by screws I2.

The arms II are provided with cylindrical dowels M at their front ends, which dowels fit snugly in holes l5 of circular cross section bored into the rear corner portions of the tray ID from the back face thereof. The dowels M are preferablyintegral with the arms and are glued in place'in the holes I5 as the parts are assembled. The major part of each arm II is commonly of rectangular cross section.

The arms I l are supported and held from turning by metal clips 20, secured to the under side of the tray In in any convenient manner, as by screws 2|. Each clip 20 has an upwardly offset bottom portion 22 engaging and supporting the under side of its associated arm H, and also has upturned side portions 23 embracing said arm II and preventing turning of its dowel M in the hole l5, even in the event that the glue joint becomes loosened.

It has been found in actual use that the quite troublesome breakage of arms at the points where they are joined to the tray is practically eliminated by the use of the clips 20, which clips prevent any turning of the arms and the placing of excessive strain on the dowels.

The clips 20 may be polished or otherwise provided with a pleasing finish and are ornamental in appearance, in addition to their utility.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

1. In association with a childs chair, a wood tray having round holes in its rear edge near the corners thereof, supporting arms rectangular in cross section and having cylindrical dowels at their front ends snugly fitting said holes and adapted to be glued therein, and metal clips secured to the under side of said tray and each having a portion extending rearwardly and offset upwardly to engage the under side of its associated arm and having up-turned side portions contacting the sides of said arm, whereby said arms are supported and held from turning.

2. In association with a childs chair, a wood tray having round holes in the rear edge near the corners thereof, supporting arms having parallel flat sides and having cylindrical dowels at their front ends snugly fitting said holes and adapted to be glued therein, and metal clips permanently secured to adjacent portions of said tray and having spaced members projecting rearward from said tray and contacting the fiat o sides of said arms and thereby effective to hold said arms from angular displacement,
