zraseaf To all whom itmay concern: 1
Be-it known that I, FRANK FESSLER, a citizen ofthe Un1tedStates,2-,nd resident of Des ble of adjustment for. varying the positions between rows of such chairs.
,The obj ect'of my invention is to, provide an opera chair so constructediand supported 7 that the chair sea-t maybe swung rearwardly,
so that-,thetotal space from front to rear occupied by the chair will-not bematerially :increased, and yet: the ,distancel between; the
chair beingioperatedanda the rowiof chairs in front may be varied for-leaving: agreater orless space through which patrons of the 20 a so mounted that theseat and back maybe ,swungor tilted. from position where the back is inclined upwardlyand rearwardly to posi- 251 tion where the back issubstantially vertical, the lower partjof the baokrbeing swung rearwardly for therebvallowing a greaterspace in front of the chair. a v
,lVith these [and other objects in :view, my invention relates qto-gthe construction, =;ar-
rangement and combination of the various parts of the device, whereby the objects conopera chair embodying my invention,.rthe,
dotted lines showing the chair in its rearward position.
Fig. 2 shows a front elevation of said chair, and
Fig. 3 shows a vertical, sectional view taken on the line 33 of Fig. 2.
In the accompanying drawings, I have shown an illustration of one form of my opera chair, having the seat, which is indicated by the reference character 10, the arms 11 and the back 12.
I provide beneath the forward portion of the seat a bracket 13 having forked, spaced, upwardly extending arms 14, pivotally secured to the bottom of the seat near opposite sides thereof, and near the forward portion thereof, as illustrated in Figs. 1 and 2. At
Specification of Letters Patent. Patgnted N 20, 19121 -Application filed--March 13,1917. nSeriaLNo. 154,621.
, its lower end the bracket 13 is provided With I spaced, forked, arms. 1!, which are pivoted to the floor upon which, the chair is supported.
Rearwardly of thebracket is a bracket 16 having-arms 14, similar to those already described, pivoted to the bottom of the seat rearwardly of" the pivot points of the first arms 14 and near the side edges-of the seat.
The bracket 16 is provided at its lower end -with arms 15, similar tothose already ,de-
scribed, and similarly pivoted to the-floor.
It should be mentioned 111 this connection that the distance between the upper ends of the brackets-13 and 16 is substantially less than; the distance betwcenthc lower ends thereof, and that the total -length of the bracket-16 from the chair seat to the floor is 117 closed at its ends. I
Rotatably but non-slidably mounted on T the bracket 16 is a bolt 18,:extending forwardly andcslightlyl downwardly. The forward portion of the bolt 18 is screw-threadecl-at 19. On the'forwardend of the bolt lS is screwed an elongated socket 20, theforward end of which travels 1n the channel 17. 1111; the practical construction and opera- 1 tion of my improvedopera chair, itmay; be noted that the; back 12 may be'arranged at any desired angle with relation to the seat 10. I have shown one arrangement of the parts, in the drawings.
Inthe normal position-of, the chair, as Shown in the drawings, the brackets 13 and 16 extend upwardly and forwardly from the floor, and the back 12 is inclined from its lower end upwardly and rearwardly with relation to the floor.
The engagement of the forward end of the socket 20 with the lower end of the channel 17 prevents the chair seat from swinging downwardly and forwardly beyond a certain predetermined position.
If a person is seated in the chair and someone attempts to pass in front of the person so seated, the person seated may push the seat of his chair rearwardly to the position shown in dotted lines in Fig. 1. It will be noted that the seat and the lower portion of the back will swing rearwardly a considerable distance, but that the upper 1 Copies pr this patent ma be obtained for engages the upper end of said channel,
whereby the rearward and downward movement of the seat '10 is limited. 1 r
It will be seen that by adjusting the lower ends of the brackets13 and 16 rearwardly Y or forwardly on the floor 1, considerable variation in thepositions and adjustment of the chair may be secured, and the socket 20 is adjustably mounted on the bolt 18- for accommodating and making possible such adjustment andfor causing the bolt 18 and socket 20 to serve as a limiting device in all positions of said adjustment. The entire-device is of very simple and inexpensive construction and permits the rearward and forward swinging movement of the'seat with very little inconvenience'ito the persons behind the seat beingmoved;
On account of the rearward position of the back 12 in the-forward position of the seat, it will be seen that the seat 10 may be moved rearwardly a considerable distance forallowing a space in front of the seat, and for reducing the total space from front to rear occupied by the seat by'swinging the back 12 from its rearward position to its substantially vertical position.
Itwill, of course, be obviousthat the dis- "tance .of-the'swing-may be varied as may be desired.
