Patented Sept. 24, 1929 UNITED STATES PATENT OFFICE FRANK B. HARMAN, OF KENOSHA, WISCONSIN, ASSIGNOR TO SIMMONS COMPANY, OF NEW YORK, N, Y., A CORPORATION OF DELAWARE METAL-FURNITURE CONSTRUCTION Application filed November This invention relates to metal furniture construction, and more particularly to chair construction, and has for its principal object to provide a strongly and rigidly mounted arm supportin post, and consists in the novel method 0 securing the supporting post on a suitable member such as the side rail of the seat frame of a chair.

Other objects and advantages will become apparent when reference is bad to the following specification when considered in connection with the accompanying drawing, wherein I have illustrated a selected embodiment of my invention, and in which:

Fig. 1 is a perspective view of a chair em bodying my improved structure, and

Figs. 2 and 3 are sections on the line and 3-3 of Figs. 1 and 2 respectively.

Referring now to the drawing and more particularly to Fig. 1 wherein I have illustrated a chair having rear corner legs 5 and front corner legs 6, the front and rear legs of each side being connected by means of a metal frame member 7 and the front legs being connected by a similar member 8, the rear legs being similarly connected. The

frame members

7 and 8 form a frame for recciving the seat cushion 17.

A conventional arm 9 is fastened at its rear end to an upwardly extending continuation of the rear legs 5 as indicated at 10, and is supported adjacent its front end by a post 11, preferably of tubular metal con struction, the upper end of which is secured to the under side of the arm 9 in any known manner. The lower end of the post is secured to and supported by the frame memher 7 in a manner to be hereinafter described. Suitable bracing members 12 and 13 may be applied to strengthen the leg structure of the chair and any desirable back structure 14 may be provided between the upper extensions of the rear corner legs 5.

The supporting post 11 which is preferably of tubular metal construction is apertured as indicated at 15 through oppositely disposed portions of the wall to receive the frame member 7 which is passed through the apertures 15 as clearly shown in Figs. 1 and 2. When the post 11 is properly positioned 9, 1925. Serial No. 67,818.

on the frame member 7, it may conveniently )8 welded thereto at exterior points of intersection as indicated at 16 and thereby permanently and rigidly held in place.

The arm and post construction above de scribed is efi ective to strengthen the chair against breakage at the connection between the legs 5 and the frame members 7, which breakage might occur due to force applied against the back of the chair. By the use of relatively wide frame members 7, as shown, I am able to produce a connection between the member 7 and post 11, which is very rigid and which strongly resists shifting of the post about the frame member, due to rearard force transmitted through the arm to the upper end of the post from the back rest.

The seat cushion 17 is supported on cross members 18 which extend between side frame members 7 and are secured in position thereon by being passed through suitable apertures 19, provided in the side rails 7, until the end thereof abuts the inner face of the outer wail of the side rail as indicated at 20. The member 18 may be secured in this position by being welded to the side rail as indicated at 21.

In order to enhance the appearance of the structure the supporting post 11 may be provided with a closure cap 22 at its lower end which cap may be of any suitable shape or of ornamental configuration.

lVhile I have described my invention in connection with a metal chair, I do not wish to be confined to its use in such a structure, and I reserve the right to make all such cl'ianges which fairly fall within the scope of the following claims which should be construed as broadly as possible consistent with the state of the art.

I claim as my invention:

1. In a chair, a seat frame including non circular side bars, a post carried solely by and rising from and fastened to an intermediate portion of one of the seat side bars and having an opening snugly receiving said side bar, a back member rising above the seat frame, and an arm member supported upon the post.

2. In a metal chair structure, the combination of a seat frame including a side rail of relatively great Vertical dimension, a back rest member extending upwardly from the back of said seat frame and rigidly connected thereto, and means for bracing said back rest member so as to maintain same in the desired position relative to said frame and so as to reinforce the connection between said back rest and frame, and comprising a post carried solely by extending upwardly from and Welded to said side rail and having an aperture snugly receiving said side rail therethrough, and an arm rigidly connected to the upper end of said post and to said back rest member at a distance above said side rail.
