IRVING L. STONE, OF BATTLE GREEK, MICHIGAN.

OPERA-CHAIR.

SPECIFICATION forming part of Letters Patent No, 325,283. dated September 1, 1885.

Application filed May 31, 1884.

To all whom it may concern:

Be it known that I, IRVING L. STONE, of Battle Creek, county of Calhoun, State of Michigan, have invented certain new and useful Improvements in Opera-Chairs, of which the following is a full and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention consists, first, in the combination, with the standards and seat connected together by the front supporting-braces, of a rear brace connected at its forward ends to the sides of the seat and having'a single central connection with the frame of the standards.

It further consists in the combination, with the standards and seat connected together by means of the forward supporting-braces, and with the hinged or pivoted back, of arms or links connected to the seat and to the lower portion of the back, whereby said links may form a support for the seat when ext-ended.

It further consists in the combination, with the standards having the swinging-back pivoted therein, of the pivoted folding-seat connected to the swinging-back by means of the arms or links, whereby the lower edge of the back is caused to move toward the rear edge of the seat when the same is lowered into its horizontal position or moved into an upright or perpendicular position as the seat is folded.

It further consists in the combination, with the standards and seat connected together by means of the forward side braces and the centrally-pivoted brace, of arms or links connecting said seat and back,whcreby the seat is allowed a free rearward and upward movement and a firm support provided for the seat when extended.

It further consists in the combination, with the pivoted back provided at its lower swinging end with the projecting arms for engaging the buffers arranged in the standards, of the pivoted seat connected to the back by means g of the arms or links,whereby the rear edge of the seat is caused to rise as the pressure of the occupant is removed therefrom.

It further consists in the combination, with the back and seat connected together by means of the arms or links, of the buffers connected to the seat to engage said arms or links when (No model.)

the seat is extended, all as and for the purpose hereinafter described.

In the accompanying drawings, Figure 1 is a perspective view of my improved operachair, a portion of the seat being broken away to show the manner of connecting the links and braces to the seat and back. Fig. 2 is a sectional view of the same, showing the seat extended for use, and Fig. 3 is a similar view showing the same folded.

The standards A may be made in any usual or preferred form, and are provided at their lower ends with projecting lugs or feet through which to attach the same to the base or floor, and at their upper ends are made in bracketform to receive and support the arms B.

The back 0 consists, preferably, of an outer frame-work made in any desired form or configuration to combine lightness and strength, the central portion being filled in with wood or other suitable material. This back upon each side, about centrally of its height, is provided with a lug or arm, B, which projects therefrom at right angles to the face of the main portion, and through which the back is connected to the standards, a pin or bolt, Z), passing through a perforation formed in the lug or arm and engaging asimilar perforation formed in the standard, and said pin or bolt forming a pivot on which the back may swing. The lower end of this back is further pro vided upon each side with a projecting arm, I), which plays within a recess, A, formed in the standard, and by its engagement with the front and rear wall thereof limits the swing ing movement of the back.

The seat portion consists of an out-er rim or band, D, having a rib, d, formed on its inner face, and upon which rib the central portion of the seat rests, said central portion being made of board or of any other suitable material corresponding to the covering or central portion of the back. The rim D, upon each side near its forward edge, is provided with a downwardly-projecting ear, d, through which the supporting and holding arms are connected to the seat portion.

An arm, E, is connected to each of the standards near their lower ends by means of a pivotpin, 0, and extending up therefrom is connected to the forward end of the ear (1, as shown, said arms forming the support for the forward edge of the seat.

A brace, F, made in V form, is secured at its central portion by means of an eyebolt or staple to a board or bar, G, extending between the two standards, as shown, and has its forward projecting ends connected to the rear ends of the ears (1, as hereinafter described.

To the lower edge of the back and upon each side are connected links or arms H, which eX- tend forward therefrom, and are connected at their forward ends to the forward ends of the brace F, the ends of saidbracepassing through perforations formed in the forward ends of the links before being engaged with the ears d, the ends of said brace being connected to the cars by passing through perforations formed therein, and being secured in place by means of a washer riveted thereon, said links H forming the connection between the seat and back. In the recess A, in each of the standards adjacent to the forward wall thereof, is mounted a rubber buffer, a, with which the projecting arms I) on the back engage when the seat is extended, the links H, which act to draw said back forward as the seat is extended for use, being of such length as to bring the arms 1) into engagement with the buffers before the seat reaches the horizontal position, and to compress said buffer as the seat is brought into said horizontal position by the weight of the user in such manner that when the weight is removed from the seat the expansion of the buffer will cause the lower end of the back to be thrown backward, and acting upon the seat through the links H to throw the rear edge of the seat upward. The lower face of the seat is also provided with rubber buffers I, arranged thereon in such position as to engage the upper face of the links H near their inner ends when the seat is pressed into its horizontal position, and forming a yielding support for the seat upon said braces.

The board or bar G,to which the brace F is connected,is secured to the standards through ribs K, formed thereon. This board or bar may have any desired form of ornamental outline, and may be provided on its rear face with a pocket or clips to hold a hat or other article. This support for the arm can, however, if desired, consist of a straight iron rod extending across from one standard to the other, as shall be found most convenient.

By having the rear edge of the seat entirely disconnected from the standards it will beseen that the seat is adapted to be folded from its rear edge or upward and away from the occupant as he rises from the seat. It will also be seen that by connecting the links to the lower edge of the back and to the forward edge of the seat a firm support is provided for the rear edge of said seat, and the usual frail pins for connecting the seat with the standards are dispensed with.

Having now described my invention, I Claim 1. The combination of the standards, the front supporting-braces pivoted to the standards, a seat pivoted to the front supportingbraces, and a second supporting-brace having a pivotal connection at its forward ends with the seat, and a fixed single central pivotal connection with a bar or frame connecting the standards, substantially as described.

2. The combination of the standards having the back pivoted thereto, the seat, arms or links connecting the'lower portion of the back to the seat, said links at some portion of their length being nearer together than the width of the seat to support the rear portion thereof, and braces connecting the seat with the standards, substantially as described.

8. The combination of the standards having the back pivoted thereto, the seat, arms or links connected to the lower portion of the back and to the forward portion of the seat for tilting the back when the seat is folded, said links being pivoted at one end nearer together than the width of the seat, with arms or links connecting the seat with the standards, substantially as and for the purpose set forth.

4. The combination of the standards, the seat, the forward side braces connecting the seat and standards, the second supportingbrace having a central pivotal connection with a bar or frame supported between the stand- V ards, the back pivoted to the standards, and the links connecting the seat with the back, substantially as described.

5. The combination of the standards, the back pivoted in said standards and provided at its lower swinging end with projecting arms, the buffers mounted on the standards in the line of movement of the projections on the back, the links connecting the back and seat, and the braces connecting the seat and stand ards, substantially as described.

6. The combination of the standards having the back pivoted thereto, the sea arms or links connecting the seat and back, said links at some portion of their length being nearer together than the width of the seat, buffers connected to the seat to engage the links when the seat is extended, and braces connecting the seat with the standards, substantially as described.
