EDVARD G. DURANT AND ELI SHUPE, OF RACINE, IVISCONSIN; SAID SHUPE ASSIGNOR TO 'II-IOMAS'KANE, OF CHICAGO, ILLINOIS.
CHAIR.
SPECIFICATION forming part of Letters Patent No. 293,724, dated February 1,9, 188,4.
Application filed July G, 1883. (No model.)
To all whom, t may con/cern.-
Be it known that we, EDWARD G. DURANT and ELI SHUPE, of Racine, in the county of Racine and State of ITisconsin, have invented certain Improvements in Opera-Chairs and other Folding Seats, of which the following is a specification.
rIhis invention relates to that class of operachairs and similar seats in which the back and the seat proper are hinged to a supporting-standard and connected with each other in such manner as to fold upward simultaneously out of the way when not required for use.
rIhe invention consists in an improved connection between the parts of the pivoted arm and back, consisting; in a bar pivoted to one of said members and arranged to s lide end wise in a groove in the opposite member, as will be hereinafter more fully explained.
Referring to the accompanying drawings,
- Figure l represents a side elevation of a portion of a standard with the back and seat arms attached, said arms being inthe position which they occupy when in use. Fig. 2 represents a similar view of thesame parts, the arms being, however, in their folded position, and the plate by which they are held in place upon their trunnions being omitted to expose the part thereunder to view. Fig. 3 is asection on the line a' x, Fig. l.
A represents a standard 0r support, which may be made of any suitable form, and which will be secured rigidly in position upon the iioor or other support.
B represents a seat-supporting arm, and C the arm by which the back is supported, the two arms having their adjacent ends connected to the standard by means of pivots or journals, as hereinafter more fully explained.
It is to be understood that, as in other chairs 'of this class, there will be a standard and pair of arms at each side of the chair, a seat and back proper being secured at opposite edges to the sustainingarms. As a means for connccting the back and seat arms and insuring their simultaneous folding action, we pivot to the seat-arm B one end of a bar, D, the opposi-te end of which Ais mounted and arranged to slide freely in a groove, a, formed in the backarm C. The bar D is connected with the two arms at such points in relation to their pivots y acter.
that upon turning the seat-arm upward to a the bar downward, at the same time causing it Ato slide endwise in the groove of the backarm, and thereby turning the latter upward also to a vertical position. Inasmuch as the sea-t in folding is compelled to swing through an arc of substantially ninety degrees, while the back, having but slight inclination, swings through a smaller are, the bar is connected with the back-arm at a greater distance from its pivot than from the pivot of the seatarm, this arrangement insuring the proper relative motion of the two arms.
For the purpose of limiting the swinging motion of the arms in both directions, we provide the seat-arm B with shoulders b and c, adapted to encounter the opposite sides of the bar D, as represented in the drawings. The bar D may be made of a rectangular, round, or other suitable form in cross-section, and it may be connected 'to the seat-arm by means of a pivot-pin or journal of any suitable char- The preferred construction is that represented in the drawings, wherein the journal or pivot is formed upon the side of the bar D and inserted in the opening formed in the seatarm, as plainly indicated in Fig. 3.
The j ournals upon which the arms are mount ed may be cast upon the standard, and may be cylindrical, conical, or spheroidal in form, the spheroidal form shown in the drawings being preferred for reasons set forth in applications hitherto filed by me.
For the purpose of securing the arms in place upon their supporting-frames, we usually employ a plate, F, as represented in the drawings, this plate resting against the inner faces of the two arms and being secured in position by means of a central bolt, G, passed through the same into the standard. Vhile it is preferred to pivot the link to the seat-arm, it is obvious that the arrangement of parts may be reversed and the link pivoted to the bacle arm and arranged to slide in a slot or groove in the seat-arm.
The essential feature of the invention consists in connecting the two arms by means of alink pivoted to one and arranged to slide 4upon the other, and it is manifest that the form and arrangement of the details maybe IOO modified 'Without departing,` from the invention, provided the mode of action indicated is reta'ined.
Having thus described the invention, what is claimed is*- l. In a folding seat, a supporting-standard, in combination With a pivoted back-arm and a pivoted seat-arm, one of said arms being` provided With a recess, as set forth, and a bar pivF Oted to one of said arms and fitted to slide in the recess in the other arm, substantially as described and shown.
2. In combination with the supportingstandard, the pivoted back-arm and the pivoted seat-arm, the back-arm being provided with the groove or recess, as set forth, and the bar D,having its forward end pivoted to the seatarm, and its opposite end fitted loosely in the groove or recess in the back-arm, as shown.
3. In combination with asupportingstandthegroovein the back-arm, as and for the purpose described.
4. In combination with the standard and thel pivoted seat-arm provided with Ithe opening, as described, the pivoted bacl -arm provided with the open groove, as set forth, the bar D, provided with the circular lug loosely seated in the opening,` inthe seat-arm and iitted loosely in the groove of the back-arm, and the plate F, applied, as shown, to retain the bar i-n -its proper relation to the back and seat arms.
