UNITED STATEs I PATENT OFFICE.

HERBERT JOSEPH HARlVOOD, OF LITTLETON, MASSACHUSETTS.

TH EATER-CHAIR.

SPECIFICATION forming part of Letters Patent No. 426,013, dated April 22, 1890. Application filed November 25, 1889, Serial N0. 331,520. (N0 modeLl To all whom it may concern.-

Be it known that I, HERBERT J OSEPH HAR- WOOD, a citizen of the United States, residing at Littleton, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Theater-Chairs; and I do 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 appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Figure l is a front View of a chair provided with the invention. Fig. 2 is a vertical transverse section. Fig. 3 is a cross-section on line 3 Fig. 2. Fig. i is a similar view on line 4 4:, Fig. 2. Fi 5 is a detached perspective view, and Fig. 6 a detached side view.

This invention relates to what are styled opera-chairs, or chairs where the back and seats are capable of being moved so as to be compacted.

The object of the invention to produce a chair which, while simple and of few parts, will still. be capable of the desired action, and one of its purposes is to produce a chair whereof the seat may be tilted. by moving the back without the necessity of touching the seat itself.

The invention consists in a chair having a tilting seat and swinging back, a finger on the back coming over the pintle of the seat, so that the swinging of the back moves the point of the fingerto one side or the other of the pintle, and thus tilts the seat, or by tilting the seat the back is moved.

In the annexed drawings, the letter A indicates the usual seat-standards. These standards are provided with forward extensions a, wherein are hollow bearings 0.. In these bearings fit the pintles b of the seat 0. On each side of the seat is secured a casting B, having these pintles b, and just above the pintles the recesses D. These recesses D have their bottoms d just above the pintles, and their walls (1' (Z slope front and back from this bottom. The seat C rests by its pintles in the bearings a, so that the larger part of the seat is in front of the bearings. lVithin the recesses I) are the lower points 6 of fingers E, which extend backward and upward, and are fastened to the sides of the back F. As shown, these points (2 are preferably rounded. The castings of which the fingers E are parts are extended upward, and at the top have the forward projections (2, provided with the pins c which project outwardly, or these pins may be made on castings separate from those of the fingers E. These pins c are provided with rubber sleeves g and enter recesses G, made in the tops of the standards A. The recesses being arranged across the standards, are longer from front to back than from top to bottom. At the bottom corners of the back are trunnions f, which enter bearings f of the standards. Projecting from these bearings are lips f which are provided with rubber abutments 7b 71:, against which the rear edge e of the seat G bears when the seat is down, as shown in the drawings.

From the construction described it will be seen that in whatever position the seat may be it can be reversed by moving the back. If the seat be in the position shown in full lines in Fig. 6, the back will be in the position also in full lines. By bringing the back forward, as indicated in dotted lines, the points eof the fingers E bear against the rear walls (1 of the recesses D and force the back of the seat downward, bringing the seat up, as indicated in dotted lines. Should the parts of the chair be in the position indicated in dotted lines, Fig. 6, the above action is reversed, the point of the finger bearing against the front walls (1 of the recesses D, and bringing the parts in the position indicated by the full lines, Fig. 0. As these movements take place the rubber-clothed pins 6 move in the recesses G, the rubber relieving any shocks incident to quick movement of the parts.

llaving described my invention, what I claim, and desire to protect by Letters Patent,is--

In a chair, the combination of standards provided with two sets of bearings, a back pivoted in one set of bearings and provided In testimony whereof I affix my signature in with fingers, and a, seat provided with pintles presence of two Witnesses.
