IMPROVED CHAIR..

Specification forming part of Letters Patent No. 56,5511, dated July 24, 1866.

To all whom 'it ma/y concern:

Beit known that I, J oHN HABERMEHL, of Wheeling, in the county of Ohio and State of West Virginia, have invented a new and useful Improvement in Chairs; and I do hereby declare that the following is a full, clear, and exact description, which will enable others skilled' in the art to make and use the same,

reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a front View of my invention; Fig. 2, a transverse vertical section of the same taken in the line of x Fig. l.

Similar letters of reference indicate like parts.

This invention relates to an improved manner of constructing the rear legs of a chair by inserting the same into a rod or cross-piece, so as to make said legs strong, and also make said rod or cross-piece answer the purpose of a roller for the seat and back to turn upon the same; and it also relates to an improved manner of constructing a device in front, under the seat, whereby the seat and back are prevented from tipping back beyond a desired distance when an inclined position is given to the chair.

It further relates to a new way of preventing the front legs from becoming disengaged from the seat by means of springs while the chair is in the act of being raised up and removed.

The general custom of tipping the chairs on their rear legs, so as to gain au easy position, cuts the carpet and oil c1oth,and renders the rear legs liable to break, and by my invention any position may be taken on this chair without any of the injurious results taking place as named.

The legs of this chair are stiftened by a number of rods, Y, Figs. 1 and 2. The front legs, at the top, are inserted into a cross-piece or rod, A, Fig. l, extending from one side to the other, which supports the front of the seat, and the rear legs are likewise inserted into a crosspiece B, Fig. 2, extending from one side to the other under the seat, at its rear end, and supporting the same. By this simple arrangement the front and rear legs are made very strong, so as not to get out of repair, and by this reason no exact measurement is required so as to make a chair of this nature work well without coming to a bearing while it is in motion against some parts and cause a friction.

The motion of the chair canbe regulated by the size of the cross-piece or roller B to any degree desired. When a rm, steady, and slow motion is required, as in a barbers or dentists chair, the size of said roller may be increased, so as to make the chair turn more hard and steady. Said cross-piece may be brought to a bear-in g against the seat its whole distance, and be all of wood, and its bed in the seat likewise of wood, by means whereof this turning device for the chair will be strong, cause a iirm, regular motion, and avoid the noise caused by a spring or the screaking of a pivot and the iilth of lubricating the same.

The chair is prevented from tipping back beyond a desired distance by reason of a loop with both of its upper ends attached to the,

seat. G, Figs. l and 2, represents said loop, formed like a half-circle or hook at its lower end, and extending on each side below rod A that distance the chair is required to tip back, so that the inclining motion of the chair is stopped when the lower end of said loop C reaches the rod A.

This device may be of common hoop-iron, wire7 or wood, and one end may be fastened to the seat only, so that its lower end will form a hook. I do not limit myself to its precise form.

A chair with its Vlegs stationary, and which does not turn its seat and back by reason of a spring under the seat, at the rear end, but turns upon a pivot or roller, will let its front legs fall and drag when the chair is being raised up and in the act of being removed.

E, Figs. l and 2, is a spring attached to the seat, so made as not to hinder an easy turning motion of the chair by extending only a small distance below the seat, and having such power as required to the weight of the front legs, being bent somewhat like a half-circle, so that when the seat comes down said spring comes to a bearing against the cross-piece A, and is pressed back, so as to admit said crosspiece between it and the seat, and hold the front legs in said position when the chair is being removed in manner named.
