OPERA-CHAIR.

SPECIFICATION forming part of Letters Patent No. 325,149, dated August 25,1885.

Application lilcdMaylT, 1884. (X0 model.)

Mi whom it may concern.-

Be it known that I, HENRY S. BACON, of Milford, in the county of NVorcester and State of lllassachusetts, have invented certain Improvements in Opera-Ghairs, of which the following is a specification.

This invention relates to chairs for theaters, railroad-cars, and other public places; and it consists in a chair having its seat pivotally connected with the frame near its front, and supported by a spring or springs near its back, and arms or arm-frames supporting the pivots of the seat, and pivoted to the back or fixed part of the chair-frame, so that they can be turned upwardly with the seat to reduce the chair to compact form, and thus unobstruct the space between each chair and the next one in front, the arm-frames being supported by the back, and thus caused to support the pivots of the seat when the armframe and seat are in position for use.

The invention also consists in the provision of yielding bearings for the arm-frames, whereby they are prevented from being absolutely rigid when in position for use, all of which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a side elevation of a chair embodying my invention, the seat and arms being in position for use. Fig. 3 represents a rear elevation, the seat and arm-frames being in the position shown in Fig. 1. Fig. 2 represents a side elevation showing the seat and arm-frames turned upwardly. Fig. 4 represents a top view of the seat. Fig. 5 represents a side view of a scat,showing a modification of the supportingsprings. Fig. 6 represents a bottom view of the seat shown in Fig. 5. Fig. 7 represents a section on line it as, Fig. 1..

The same letters of reference indicate the same parts in all the figures.

In carrying out my invention I provide a fixed back, a, which is preferably pivoted on a vertical axis supported by a base, a, which may be secured rigidly to the fioor,if desired, said base and back constituting the main frame of the chair. To the back are pivoted at I) 1) two frames,c c,whieh are adapted to swing on their pivots b, so as to project forward from the back, shown in Fig. 1, or to stand across the edges of the back, as shown in Fig. 2. Each frame 0 is supported in the position shown in Fig. 1 by the bearing of lugs c e on its inner side against the edge of the back a, the lug 6 bearing against the rear edge of the back above the pivot I), and the lug 0 against the front edge below the pivot. Then the frames 0 are in this position,they are in effect parts of the main frame, and their upper portions constitute the arms of the chair.

9 represents the seat, which is pivoted near its forward edge at h to the frames 0 c, and is supported at its rear portion by springs i 13, so that it can rise and fall at its rear portion,like the seat shown in Letters Patent No. 288,608, granted to \V. H. Bate, November 13, 1883.

The pivotal connection of the seat to the frames 0 c,and the absence of any positive connection between the seat and the fixed portion of the frame, enable the frames 0 0, when turned upwardly, to also turn the seat upwardly, as shown in Fig. 2, thus putting the chair in compact form and creating an open space at the front of the chair.

The yielding support for the back of the seat-,aiforded by the springs t i, makes the chair much easier to the occupant than any so-callcd operachair heretofore produeed,while the independent arm'frames pivotally connected to the fixed frame and to the seat enable longer and more comfortable arms to be provided than usual in this class of chairs.

I prefer to provide the lugs e c with springs s, which are interposed between said lugs and the back a, and constitute yielding bearings which enable the arm to yield slightly to downward pressure when they are in position for use, and prevent them from having an absolutel y rigid bearing on the back. Said springs may be blocks of rubber, or of other suitable construction.

The springs i may be supported by the chairframe, as shown in Figs. 1, 2, and 3, or by the arm-frames c c, as shown in Figs. 5 and o.

I claim 1. The combination, with the standard, of the main frame or back attached thereto, the arm-frames pivoted to the back, the seat pivoted to the arm-frames near its front, and supportingsprings on the standard under the rear of the seat.
