UNITED STATES FRANK D. WILT, OF ALLENTOWVN, PENNSYLVANIA, ASSIGNOR TO BENNO F. SOHLEGEL, OF SAME PLACE.
SPECIFICATION forming part of Letters Patent No. 343,654, dated June 15,1886.
Application filed December 31, 1885. Serial No. 187,272. (No model.)
To all whom it may concern:
Be it known that I, FRANK D.,WILT, a citizen of the United States, residing at Allentown, in the county of Lehigh, State of Pennsylvania, have invented certain new and useful Improvements in Reclining-Chairs, of which the following is a specification, refer-' ence being had therein to the accompanying drawings.
This invention has relation to recliningchairs of that particular construction which embodies a suspended seat and back portion pivotally connected to each other, and provided with means for adj ustably retaining the seat and back in a desired position.
Heretofore chairs of the particular kind to which my invention is, in this instance, applied, have been constructed with a supporting-link pivoted to the front portion of the frame-work and to the sides of the seat-frame near its front edge, the links serving to sup-' port the seat and permit of a forward and rear ward movement of the same, while the back corners of the seat and the adjacent lower edge of the back were also suspended from the framework by links, of which one was connected at two points to the frame-work ofthe back and at one point to the main frame-work--that is, at a point in the arm portion thereof-while the other of said links was secured to the side of the seat-frame and to its companion link, whereby, in any inclination of the back, the seat is carried forward, so that these two portions of the chair could be brought into the same horizontal plane.
The device employed'for retaining the parts in a desired position comprised a rack-bar having coarse teeth connected to the seat portion, arranged centrally thereunder, and passing over a rod arranged transverselyunder the rack-bar, so that the rod could be raised into the path of the rack-bar to take into one of the teeth thereof, where it was intended to be held merely by the friction of the rod and bar upon each other.
It has been found by experience that the .devices described for retaining the chair in a desired inclined position were unreliable, in that by a slight movement of the sitter the rod would fall by gravity out of connection with the rack-bar, and, by reason of the weight of the sitter, the seat and back of the chair were thrown out of a desired position.
Reclining-chairs have also been constructed with a base having curved upper edges, upon which theseat-frameis mounted, and provided with one member of a rack-and-pawl mechanism, the other member of which was arranged in the base, whereby the seat portion could be adj ustably secured in a desired position.
'The primary object of my invention is to provide more satisfactory devices for maintaining the moving parts of the chair in a de sired adjusted position. I also provide other means than the weight of the sitter forreturning the back and seat from an inclined to their normal position, and a compactlyarrangcd foot-rest; and my invention consists in certain features of construction hereinafter described, and particularly pointed out in the claims.
Referring to the drawings, Figure l is a side elevation with portions broken away, and Fig. 2 is a central vertical section of a chair provided with myimprovements. Figs. 3, 4, and 5 are details hereinafter described.
Like letters of reference indicatelike' parts in all the figures.
In this instance, what I designate as the frame-work A of theseat portion of the chair is mounted upon a base, B, the lower edges being rounded off to form rockers, and the usual coiled springs, C, are employed to make the proper connection between the base and the frame work. If desired, however, the frame-work may be extended in the form of legs, when it is desired to have other than a rocking-chair, as shown by the dotted lines X X, Fig. 2.
To the seat portion of the frame-work A, as at A, and upon each side of said frame, is pivoted the supporting-link A the opposite end of which is pivoted to the seat-frame C at A, while the link A is pivoted to the same ,franie-work at A, and rigidly secured, as at D D to the frame of the back D. A short link, 0, is pivotally secured, as at G", to the seat 0, and to the link A at O. This arrangement of suspension-links is duplicated at each side of the seat and back, so that when the back is downwardly inclined the seat r00 moves to the front, as hereinbefore mentioned. I lay no claim to the particular arrangement of the suspension-links above described.
One feature of my invention has particular reference to the retaining rack-bar E, which is pivoted to the seat-frame at E, and extended opposite the pivot to form a hook or arm, E the lower edge of the bar being provided with ratchet-teeth E. At the hook E is connected a coiled or it may be any other suitable form of spring, F, which is extended rearwardl y and connected to the framework-- for example, by means of a hook, F. The rack-bar passes over a fixed tooth, G, secured to the inner surface of theframe-work, where, also, is provided a cam-lever, H, having a thumb-piece, H, arranged above the bar E, so that the same may be operated to force the bar downwardly upon the fixed tooth G.
by the construction thus far described it will bcseen that the single rack-bar arranged at one side of the seat, and between the frame thereof and the frame-work of the chair, is adapted to perform the desired functions in the following manner: \Vhen desired tochange the inclination of the back of the chair, the canrlever H is raised to a vertical position, as shown in Fig. 3, when, by the tension of the spring 1*, the free end of the bar is elevated so that the teeth on the lower edge thereof pass over the fixed tooth G, whereby free movement of the rack-bar and a forward or backward movement of the seat is possible. Now, it will be' noticed that as the back is downwardly inclined and the seat moved to the front. the tension or strain upon the spring F is increased, and when the chair is brought t the desired ad;justmentas to the inclination of its back-the same is retained in position by simply turning down the cam lever H, whereby the bar is depressed and brought and retained in firm contact with the fixed tooth. It will be. further noticed that when it is de sired to bring the back upward to or nearly to, an upright position, simply raising the camlever H releases the bar from contact with the fixed tooth and the tension of the spring serves the desired purpose, whether the chair is occupied by a sitter or not. When the rack-bar is once forced down upon thefixed tooth by the action of the canrlever, the
not possibly release the bar, nor can the inclination of the chair be changed by any tionable feature is completely overcome.
In order to provide a simple and satisfactory foot-rest, I remove the lower portion, 0*, of the front board, 0 of the seat, and attach the same to a frame comprising opposite side rails, I, and a front rail, 1'- I also secure, the foot-board proper, J, which may or may not be upholstered, as shown, to the inner surface of the side rails, L, as at J, so that said footboard may turn upon its pivots upwardly between the side rails and over onto the end rail, 1, and front board, 0 as shown in dotted or the fixed portion of the chair.
lines, Fig. 2. No rear crossrail is employed, in order that the side rails may move within and along the inner surfaces of the seat-frame, and because said rear cross-rail would interfere with the springs K of the seat. The springs K of the seat-those arranged near its front-are supported upon a cross-board or cleat, K", whereby a recess is formed for the reception of the foot-board and its adja cent supporting parts when moved inwardly or closed after the manner of a drawer, and when so closed the front of the seat proper presents an unbroken, finished appearance. I support the foot-rest by passing said rails I thereof over lugs, L, formed on the castings L. secured to the inner surface of each of the side rails of the seat-frame beneath the cleat K. At the end of each side rail, I, is secured a casting, M, having alug, M, adapted to take 1 into notches or teeth L, formed in the rear edge of the castings L, so that when the footrest is withdrawn the lugs M come into contact with the edge of the casting L, and by placing the lugs into one or the other of the teeth L different inclinations of the foot-rest with relation to the seat may be secured, as
clearly indicated by dotted lines, Fig. 4. I do not, however, claim the construction of the foot-rest shown and described.
As before indicated, I do not limit my invention to reclining-chairs mounted upon a base, as a rocker; nor doI limit myself to the exact details of construction herein shown and described and not claimed, but reserve my right to vary the same in any manner and to any extent, provided any changes and modifications which I may make are the result solely of mechanical skill of persons conversant with the construction of articles of furniture of this class. By reason of the arrangement of the links A A, the former being below and the latter above the movable seat, portion, said portion moves in an irregular line, and therefore the rack-bar E must be pivotally connected with either the movable Heretofore, as ispossi-ble, a fixed rack-bar has been secured to the movable portion, but said movable portion was supported upon or moved in the arc of a true circle, to which the fixed rack-bar conformed. weight and movements of an occupant can! Having thus fully described my invention, its operation and construction, what I claim,
. and desire to secure by Letters Patent, isordinary use of the. same, so that this objec- 1. In a chair of the class described, a rack- 1 bar pivotal'ly secured toa movable seat-frame,
