UNITED STATES PATENT CEEICE.

CHARLES Cr. PEASE, OF CHARLESTOWN, MASSACHUSETTS.

CHAIR FOR PHOTOGRAPHIC PURPOSES.

Specication forming part of Letters Patent No. 53,03S, dated March 6, 1866.

To all whom it may ooncerm Be it known that I, GHARLEs G. PEAsE, of

Charlestown, in the county ot' Middlesex and State of Massachusetts, have invented a new and useful Improvement in Chairs for Photographic or other Purposes; and I do hereby declare the same to be fully described in the' following,r specification and represented in the accompanying' drawings, 0f which- Figure l is a front elevation, Fig. L a rear view, and Fig. 3 a vertical section, of a chair provided with my invention.

In these drawings, A denotes the seat-frame ofthe chair. B is the back thereof, the latter having a slide-bar, a, projecting down from it and through a standard, b, erected on the seatframe.

rlhe bar a, placed in a recess of the standard, goes between the said standard and a jaw, c, erected on theseat-irame. A clampscrew, d, passes through thejaw and a long slot, e, formed vertically in the slider a, and screws into the standard or a piece ot' meta-hf, fastened thereto. By means of the jaw and the clamp-screw the slide a may be clamped in position when the back is at any desirable altitude relatively to theseat. The said back, near its Lipper part, has a circular aperture, g, made through it to receive a head-rest, G, connected to one extremity otl a rod, D, by means oi' a balland-socket joint provided with a clamp-screw, t'. This rod D is supported by and so as to be capable of being slid transversely on a standard, E, projecting from the back,

- and provided with a clamp-screw, k, for fixing the slide-rod in position.

rIhe above chair is specially designed for supporting an infant or small child while' he or she may be having aphotographic or daguerreotypic likeness taken. While the back may be adjusted so as to afford a good support for the child at the shoulders and back thereof, the head-rest and the back of the chair, or the head-rest alone, may be employed to excellent advantage in sustaining the head of the child. While the edges ot' the aperture g will afford more or less lateral support to the head, the rest Gr may be adjusted and employed so as to give the rearward support to it.

By means of the movablejaw applied to the standard, and by having the clamp-screw go through the jaw and a slot in the back-slide and screw into the standard, I am not only enabled to prevent the clamp-screw from doing injury to the slide, which it would be likely to were it to screw into the standard and directly against the slide, but I am able to very firmly clamp the slide to the standard. By adjusting the head-rest so as to be Hush with the back it will have the appearance of being al part of such back, which, in fact, it may be supposed to be.

The chair made as hereinbefore described may sometimes be used to advantage by a dentist in the practice of his profession with respect to a small child. p

Ido not claim the combination ot' a headrest with the back of a chair, as 'such is Well known and in common use; but

I claim- The arrangement 0f the adjustable head-rest so as to work through the chair-hack, and the construction of such bac-k with an opening, g, to receive the said rest, as specified.

- C. G. PEASE.
