OPERA-CHAIR.

Specification of Letters Patent.

Patented May 11, 1920.

Application filed April 10, 1918. Serial No. 227,811.

To all whom it may concern:

Be it known that I, FRANK Fnssnnn, a

citizen of the United States, and resident v of Des Moines, in the county of Polk and State of Iowa, have invented a certain new and useful Opera-Chair, of which the fol- Still a further object is to provide such a chair mounted in such manner as to be adjustable rearwardly or forwardly, and having simple and effective means whereby the limits of the adjustment may be quickly and easily varied' With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of the device. whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which: 7

Figure 1 shows a front elevation of an opera chair embodying my invention.

Fig. 2 shows a side elevation of the same, the chair being shown in full lines in its forward position, and in dotted lines in its rearward position.

Fig. 3 shows a detail view of part of the tilting mechanism viewed from the side, and

Fig. 4 shows a detail view of the same part of said tilting mechanism, viewed from the front.

In the illustration of my invention shown in the accompanying drawings, I have used the reference numeral 10 to indicate generally the seat of an opera chair, having a back member 11 and arm rests 12.

I have provided a pair of brackets, each comprising a substantially upright member 13, designed to be secured to the back 11 and to extend downwardly to position adjacent to the rear edge of the seat 10. Formed on the portion 13, at its lower end,

is a forwardly extending portion 14 derearwardly signed to be secured to the under surface of the seat 10.

On each bracket member 14 is formed a bearing 15, in which is mounted a transverse shaft 16. Each bracket member 14 also has on opposite sides of the bearing 15, and preferably spaced laterally therefrom somewhat, a pair of downwardly extending screw-threaded sockets 17. Received in the screw-threaded sockets are bolts 18.

The bearings 15 are located preferably of'the transverse center of the seat 10. ocated forwardly of said transverse center are brackets or plates 19, each having abearing 20, the bearings 20 being arranged in alinement with each other across the chair. Each of the plates or brackets 19 has, forwardly and rearwardly of the bearing 20 thereon, downwardly extending sockets 21 which are internally screw-threaded and are similar in construction to the sockets 17, and receive bolts 18 similar to those already described.

Below the seat is a pair of supporting members 22 and 23. The supporting member 22 has at its upper end, spaced upwardly extending arms 24, operatively connected with a transverse shaft 25 mounted in the bearings 20. The member 22 has at its lower end, spaced arms 26 pivotally con nected at their lower ends with floor brackets 27.

The rear supporting member 23 has spaced arms 28 at its upper end, similar to the arms 24, which are operatively connected with the transverse shaft 16. The member 23 has at its lower end, spaced arms 29, similar to the arms 26, pivotally mounted on the floor brackets 30.

On each of the arms 24 are rearwardly and forwardly projecting lugs 31 designed to serve as stop or limiting devices, and coacting with the heads of the bolts 18 mounted in the sockets 21.

On the arms 28 are similar stops 31, de-

signed to coact with the heads of the bolts 18 in the sockets 17.

It will be seen that when the seat 10 is swung to its forward position of move ment, as shown in full lines in Fig. 2, the

heads of the bolts in the rear sockets 21 and o 17 respectively will engage the upper surfaces of the rear lugs .31 on the respective arms 24 and 28, and limit the forward and downward swing of the seat. This illustrates the position of the seat for ordinary use.

However, if a patron of the theater should desire to pass down the aisle in front of the seat being released, the person sitting may push his seat rearwardly to the position illustrated by dotted lines in Fig. 2, whereupon the heads of the bolts 18 in the forward sockets 17 and 21 would engage the forward lugs 31 on the respective arms 24 and 28, and limit the rearward and downward movement of the seat.

The limit of movement of the seat may be readily adjusted by screwing the bolts 18 inwardly or outwardly.

Many of the advantages of my improved opera chair may be seen from the foregoing description.

It will be seen that my device is of very simple and inexpensive construction, and that it makes possible an easy adjustment and swinging of the seat for accommodating the patrons of the theater.

Some changes may be made in the con struction and arrangement of the parts of my improved opera chair without departing from the essential features and purposes of my invention, and it is my intention to cover by my claim any modified forms of structure or use of mechanical equivalents which may be-included within its scope.

In this connection it maybe mentioned that it would be very easy to accomplish the same purpose as I have here accomplished by the construction shown, by putting sockets on the floor brackets 27 and 30 and mounting bolts therein and placing lu 's on the lower parts of the arms 26 and29. here is some advantage in the construction here shown, in that the floor may be more easily than if the bolts and sockets were placed at the lower ends of the supporting members 22 and 23. V

I claim as my invention:

In a device of the class described, an opera chair having a seat member, bearings disposed adjacent to the front and" rear edges of the seat member in position spaced from each other and secured to the" bottom of the seat member, supporting members pivotally mounted in said members comprising elongated strips of material, means for pivotally connecting the lower ends of said supporting members to the floor, stop devices extending downwardly from said bearings at either side thereof, means for adjusting the relative vertical position of the contact surfaces of each of said stop members and shoulders of substantially triangle shape formed integral with said supporting members andextending laterally therefrom, to a position where the upper surfaces of said shoulders may contact with said stop. members, the parts being so arranged that theengagement of each of the stop members with the shoulders 'may be independently adjusted and the shoulders may form reinforcing members to prevent buckling of the supporting members.
