To all whom t may concern Be it known that l, DAVID E. EMANUEL, a citizen of the United States, and resident of Des Moines, in the county of Polk and State of llowa, have invented a certain new and useful Opera-Chair, of which the following is a specification.

The object of my invention is to provide I an opera chair of simple, durable and inlcontemplated are attained,

expensive construction.

A further object is to provide an opera chair of the type having a seat adapted to slide rearwardly to-permit persons to pass through the aisle with a minimum of interference and inconvenience.

A further object is to provide an opera chair having a back pivoted near its upper portion and having a seat mounted with relation to said back and adapted to travel into a slot in the back and also having a partpivotally mounted on the back, both of the parts of said seat being capable of pivotal movement with relation to the back when the seat is raised.

My invention consists in the construction,

arrangement and combination of the vari device whereby the objects as hereinafter more fully set forth pointed out in my ous parts of the claims and illustrated in the accompanying drawings, in which:

Figure 1 shows a front elevation of a chair embodying my invention. Fig. 2 shows a vertical sectional view of the same taken on the line 2-2 of Fig. 1. Fig. 3 shows an enlarged vertical seetlonal view of the lower part oit the back and the rear portion oit the seat, ytaken lon the line 3-3 ot Fig. 1. Fig. A' shows a vertical transverse sectional view, taken on the line 4 4 of Fig. 3.

1n the accompanying drawings, l have used the reference numeral 10 to indicate' generally the lower support of a chair which may be of any desired form, for instance, as that of a pedestahzas shown in my drawings.

0n the upper portion of the supporting member 10 are suitable trame members 11.- My improved chair has the'spaced upwardly extending back members 12, and suitable arm rests 13, which may be of any desired construction.

Fivotally mounted between the upper ends or the members 12 is a back member 14:. rlIhe members 12 are inclined from their lower ends upwardly and -slightly rear- Mounted upon the frame 11 1s a substan-- tially rectangular frame 15 having approxlmately the form of a sheet of metal or the like, with its central portion cut away. At the side of the frame 15 are upwardly eX- tending members 16, at the upper ends of which are inwardly extending members 17. At the rear outer corners of the frame 15 are upwardly extending ears 18, pivotally connected with the back. Mounted upon the frame 15 is a suitable seat member 19 having in its sides grooves to receive the members 17.

In the forward portion of the frame 11 are rollers 20 on which the frame 15 travels. It will be seen that the seat 19 may slide with relation to the frame 15 and also that the forward end of the frame 15 slides freely on the rollers 20, and that the rear" ward end of said frame is supported by the back 1A and lswings thereon. ln this connection it may be mentioned that the rear portion of the seat 19lcomprises a plural ity of transverse members 21 connected by a flexible strip 22. rllhe lower portion of the back 14. is formed with a slot 23, and the parts are so constructed and arranged that when the seat 19 is in its forward position and is pushed rearwardly, the members 21 will slide upwardly into the slot 23. The back 1A comprises a wooden member covered on front and back b a pair of metal sheets. rlFhe wooden mem er extends to the lower ends of the metal sheets, anda space below the wooden member forms the slot 23.

1n the practical operation and use ot my improved seat, it will be noted that the seat member 19 projects forwardly beyond the other partsof the seat. Assuming that the seat is not occupied, the seat member 19,. and the frame '15 may be tilted upwardly to the position shown by the dotted lines in Fig. 2. en it is desired to occupy the seat, the seat member 19 and, trame 15 are -lswung downwardly to the position shown over the rollers 20 and the back 14 swings rearwardly on its pivot points. On the forward end of the frame 15 is a downwardly projecting member 24 which engages one of the frame members l1 when the back 15 has reached perpendicular position, and lthereupon the seat 15 slides rearwardly with relation to the frame 15 and the members 20 slide upwardly into the slot 23. When the i the fact that the back may be inclined to' various angles to suit the convenience of the occupant of the seat.

My improved chair is of comparatively simple construction, and can be manufactured at a small expense.

It will be understood that the chair will be constructed with curved edges, so that with such an arrangement of the parts, there will be no danger of tearing the garments of the user.

It will be understood that some may be made in the construction and arrangement of the parts of my improved opera chair without departing from its essential features and purposes, and it is my intention to cover by this application any such changes which may be included Within the scope of my claims.

My seat member is made partially colchanges lapsible for reducing it to the narrowest width from front to rear, for accommodating passers-by and at the same time affording suiiicient room for the occupant.
