Z 0 all whom t may concern.'

Be it known that l, JOHN LEE, a citizen of the United States, residing at Klamath Falls, in the county of Klamath, State of Oregon, have invented-new and useful Auditorium, Assembly-Room, or Theater Chairs or Benches, of which the following is a specification. Y

My invention relates to improvements on an original mechanical combination as designed and applied to any conventional or standard form of auditorium or assembly room or theater chair, and the objects of my improvements and inventions are: Y

l. To construct a retracting, suspended, gravity operated chair, seat or bench which will permit by the action'of seat occupant, of increased space being formed at will between him and other objects or chairs in front and thus permit freer passage through wider aisle to any passer-by, without the necessity of the seat occupant rising.

2. To afford a more rigid and stronger type of chair by placing a through rod in the standards of said chair. f,

3. To afford a stronger lseat anchorage by supporting the same on said through rod and also on two hinges thereby making four supports.

4. To bring about the locking and holding of all movable parts of the chair when the seat is thrown up in vertical position.

I attain these objects by the mechanism illustrated in the following drawings in which- Figure l is a side view of chair, the nearest standard being removed and front half of exposed support panel broken to show interior.

Fig. 2 isa front-rear view with half vertical section at mid-point of back view at right.

Similar letters refer to similar parts throughout the several views.

The standards S S, the back, the seat G with ribs M M underneath and the support ing side panels FF, constitute the principal parts of the chair. The occupant seating himself on seat G is in a normal resting position, the weight of his body being partly carried by the xed through rod B to standards, and partly by hinge bolts H H in side panels F F. (In the drawing these bolts being in line with rod B, do not show separately). The side panels are lheld up by anchorages 7' 7 of hangers R R on the PAUL SATTER porting side panelsF F by inipinging on fixed rod- B, with slots of properdepth, Y,

lock seat Grand also the side panels from moving up or down and serve as a stop for side panels F F to limit the forward motion thereof. Y

Desiring to retract the chair, Vthe occupant places feet at K, either on rioor or over cleat K, and by a rearward motion of the vbody pushes the chair seat as well as the supporting side panels and back toward the rear to a point determined by ylimits of grooves g g which more with the seat over fixed bolt B. rfhis action is brought about by hangers R R swinging about anchorages r 1, carrying supporting side panels F F to the rear, also elevating and moving rearwardly points o o on the side panels in an arc of a radius equaling the length of hangers R R which move .about centers fr r. At the same time the seat moving back on bolt B is retracted and elevated an equal amount. Gravity tends to act and move seat Gr forwar again on inclined grooves g g, and keep it there. "N hen the chair is retracted, a clear space in front of occupant of width equal to length of grooves g' g is gained. action of spring Y fastened to hangers It R and through rod B, also assists the seat with its attached side panels to return, and takes up any indirection of movement on the part of seat G on grooves g through which the through rod B passes.

The chair being retracted with seat andl occupant to therear, allows clear space in front with wider aisles, and it is onlynecessary for the occupant to relieve the backward pressure on the chair, when gravity returns the seat to normal position together with the assistance of the spring which resists a decided effort on the part of occupant to move it from normal position.

' The swinging action of hangers R R may be maintained'in the same vertical plane by rolling checks between supportingside panels F F, and standards S S, while the travel of seat G on grooves g, is controlled by collars C C, on fixed through rod B placed at proper distances apart to retain ribs M M in a correct forward and back line. rlhe move-` ment of supporting side panels F Fat their upper edges is approximately in a straight rising line backward, and these may be Covered by a cap or hood cover Z which would protect the clothes ofV occupant from becoming caught as side panels F F vmove backward and forward, and also by containing and checking side panels F F, would tend to keep the action of the chair in line.

-To leek and hold all vmovable parts of the chair when the seat G is thrown up in clear about hinge bolts H H', Circular groove'g g is madeV in ribs M M, which seat Gr is,

revolved about hinge bolts 'H H, moves on the through rod'B `looking the seat back and Y Vand having angularly disposed slots theren in, one of saidA slots being arcuate Yfor Vel'- tioal movement of theseat about `its pivot; a'bo'lt Connecting the'side standards and passing through said slots so that engagement between thebolt and slots will allow the seat to move rearwardly or upwardly,

and a retraetile spring Connected to the links and to saidV bolt to cause the seat to resume a normalpositlon when moved therefrom. JOHN PAUL SATTERLEE.
