CHAI-R.
SPECIFICATION forming part of Letters Patent No. 478,131, dated J' uly 5, 1892.
Application filed .Tune 20, 1891.v Serial No. 396,913. (No model.)
To all whom, i may concern:
Beit known that we, ARTHUR M. RICHARDS, of Bloomington, McLean county, and IRWIN VEEDER, of Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Chairs, of which the followingis a specification.
Our invention relates to chairs having their backs pivoted so as to yield to the occupant, and is intended to provide a device which will permit the chair-back to yield in one direction only, and which will on the back being relieved of pressure restore it to its original position.
In the accompanying drawings, Figure l is an elevation of a chair to which our improved device is attached, a portion of the chair arm and back being broken away to show the attachment. Fig. 2 is adetail View, on a larger scale, partlyin section, of the attachment and a portion of the chair back and arm connected therewith. Fig.3 is asectional viewof a portion of the attachment secured to the chairback, as seen from the-right of Fig. 2.
A is the varm of the chair, to which is affixed a plate B. From the inner side of the plate B a stud C projects. Said stud is of polygonal section and fits a sleeve D, on which is journaled a casing E, affixed to the frame F of the chair-back, the sleeve D being shouldered to receive the casing and to allow the back to tilt. Instead of making .the stud C of polygonal section, any other well-known means for preventing the sleeve fromjrevolving on the stud may be employed. The sleeve D has a projecting lug d, in apposition to which is a lug e, secured in or forming a part of the case E. Surrounding the encircling sleeve D is a C-spring G, the ends of the spring bea-ring against the lug d and the lug e, respectively, as shown in Fig. 3. The ends of the spring G are preferably curved outwardly, and the faces of the lugs d and c, against which they bear, are correspondingly hollowed, as shown, the spring G being thus kept in place, no other provision being necessary for that purpose. To limit the distance which Vthe back can yield, a short stud H upon the plate B projects into a slot I in the casing E. The dotted lines in Fig. 3 show the position of the parts when the back yields.
the manner shown in the patent granted to i' Arthur M. Richards October 7, 1890, numbered 437,93S.
The present device, in a combination employing the spring J,'serves as a positive stop when the chair-back is released from the pressure of the occupant, so that uniformity in the position of the chair-back `is secured, such uniformity being especially desirable when a considerable number of fixed chails arranged in rows is used, as in public halls and theaters. Y
Vhile we have hereinabove described the plate B, supporting the stud C, as secured to the chair-arm and the casing E as being secured to the part of the chair-back marked F, it is evident that the relative positions of the stud-supporting plate B and casing E to the parts A and F may be reversed without altering the mode of operation of the device; `or, what amounts to the same thing, the part A may be considered as belonging to the chairback and the part F as belonging to the chairarm, instead of vice versa, as hereinabove described. The first construction herein described, however, will be generally preferable where the spring J is used, as said spring is then covered by the upholstery of the chairback.
We claim- 1. The combination, with a chair and its back pivoted thereto. of a casing attached rigidly to one part and a stud attached to the other, a sleeve fitted upon said stud and forming a journal for said casing, a lug upon said sleeve, and a lug in apposition thereto attached to the case, and a C-spring surrounding said Vsleeve and bearing at one end against.I the lug on the sleeve and at the otheragainst the lug attached to the case, substantiallyas described.
2. The combination, with a chair-back and a support therefor, of a yielding pivotal attachment consisting of a casing attached to one of said parts and a stud C, attached to the other, a sleeve rigidly seated on the stud, a cas- IOO ingjournaledonthesleeve,alugdonthesleeve, I journaled on said sleeve, a spring G within a IngP e on the casing in apposition to said lug I the casing` C, tending to maintaln contact beon the sleeve, and a spring tending to lnaintween the lugs cl ande, anda spl'ingJ, secured,
tain contact between said lugs, substantially respectively, at its opposite ends to the pivoted part and the support therefor.
as described.
3. In means for pivotally attaching a chairback to a support, the combination of the cas- ARTHUR M.
