REUBEN RICHARDSON, OF HUNTSVILLE, OHIO.

CHAIR.

SPECIFICATION forming part of Letters Patent No. 272,901, dated February 27, 1883,

Application filed February 3, 1882. (ModeL) To all whom it may concern:

Be it known that I, REUBEN RICHARDSON, of Huntsville, in the county of Logan and State of Ohio, have invented certain new and useful Improvements in Chairs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to chairs, and more particularly to that class of chairs which are adapted to be revolved upon a supporting standard, whereby they may be turned under a desk or to one side, out of the way, when not required for use.

The invention consists in the improved construction and combinations of parts hereinafter fully described, whereby the chair-seat is supported by a loop-bearing, the latter being pivotally connected to a stepped standard, thus firmly bracing the chair and permitting its being turned under a desk when not in use.

In the drawings, Figure 1 is an isometric view of a chair constructed in accordance with my invention, in connection with a desk-platformand desk, the chair being in position to be used. Fig. 2 shows a sectional view with the chair turned under the desk. Fig. 3 is a perspective view of the loop-bearingand chairpivot detached, and Fig. 4. is a similar view of the supportingstaudard.

A represents a post or standard, secured to an enlarged base, B, the latter being perforated, and adapted to be secured by screws 1) to the floor or desk-platform G, and internally screw-threaded to receive the screw-threaded end a of the post.

D represents a desk. The standard is preferably so arranged relative to the desk that a linedrawn from the inner edge of the top of the desk to the door 0 would pass centrally through the standard. Thus the standard will beout of the way when the chair is turned as shown in Fig. 2. A slight variance from this made, if desired. The standard is formed with a step, a, near its base and a second step or hearing, a, near its upper end, a which latter is pointed to receive the looped bearing of the chair.

E represents the chair-seat, which may be of any desired construction. To its under side is secured, by screws 6 or other means, a metallic or other disk, F. Depending or projecting from the center of the latter is the chairpivot G, of tapering form.

H represents the chair hearing or brace, consisting of a strip of metal looped or bent upon itself to form the supports it h. The latter are parallel with each other for a short distance from the bend, and each provided with a perforation or pivot-bearing, t, the latter being in the same vertical'plane to receive the pivot G of the chair. The lower brace, h, of the bearing H then extends forward and downward at an incline, and terminates in a horizontal bend, hfiwhich is provided with a perforation, W, of a size to allow the brace h to be slipped over the upper portion of the standard A and rest upon the lower step, a. The upper brace, IL, of the bearing H then extends horizontally forward to the front of the chair-.

seat, where it is bent slightlydownward and forward, as shown at i, and provided with perforations i adapted to fit over the upper end, a, of the standard and allow the brace to rest on the step (t of saidstandard. It will be apparent thatwhen the chair is thus secured it may be freely revolved both on the pivot G and around the standard A, and readily removed when desired. The looped strip affords a firm and secure bearing for the chair, as it forms both a horizontal and diagonal brace for the latter; and by the construction of the standard with the upper and lower steps or bearings and pointed upper end the perforated strip H may be readily removed.

The several parts of my improved chair are all of simple construction and may be manufactured at a small cost. 7

Many slight changes in the details of construction might be resorted to without departing from the spirit of my invention, and hence I do not limit myself to the precise construction shown in the drawings, but reserve the right to make such alterations in form as may properly fall within the scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination, with the chair-base B and brace and thereby furnished with an extended IO standard A, the latter constructed with the bearing therein, substantially nsser forth. upper and lower step-bearings, (t a, and the In testimony whereof I have signed this loop-brace H, having its upper arm journaled specification in the presence of two subscrib- 5 at its end on the upper step-bearing, (6 and ing Witnesses.
