CHAIR.

Specification of Letters Patent.

Original application filed April 5, 1907, Serial No. 366,531.

Patented Oct. 13, 1908.

Divided and. this application filed February 1, 1908.

Serial No. 413,804.

To all whom it may concern:

Be it known that I, ANTON G. EYLEs, a citizen of the United States, residing at Cedar Rapids, in'the county of Linn and State of Iowa, have invented anew and useful Improvement in Chairs, of which the following is a specification.

My invention relates particularly to chairs provided with adjustable foot-rests; and my primary object is to provide improvements pertaining to foot-rests and mechanism for actuating the same.

The invention is illustrated in its preferred embodiment in the accompanying drawings, in which- Figure 1 represents a vertical sectional view of a chair constructed with my improvements, the foot-rest being shown in the folded or sheathed position; Fig. 2, a broken sectional view showing the foot-rest in an extended position; Fig. 8, a broken front elevational View showing the foot-rest bars in section, the section being taken as indicated at line 3 of Fig. 2; Fig. 4, a horizontal section taken approximately as indicated at line 4 of Fig. 1, the dotted lines indicating the extended position of the footrest; Fig. 5, a broken, rear elevational view of the chair; and Fig. 6, a broken sectional view taken approximately as indicated at line 6 of Fig. 1.

' In the construction illustrated, A represents the frame of a chair having side-members A formed with arms A A seatsupporting and guideforming cleats applied to the inner surfaces of the side-members A A, a bottom connecting the side members A A a front cross-member connected with the front ends of the cleats A" and with the front edge of the bottom A; A, a cross-member connecting the rear legs which form a part of the side-members A B, a seat shown as removably supported on the cleats A C, a back provided with ad justing mechanism C of the character fully described and claimed in my pending application No. 366,531, filed April 5, 1907 (Patent No. 880,206, granted February 25, 1908), of which application the present application is a division; and D, my improved footrest which is carried by slide'bars D D rods connecting the front portions of the said slide-bars with levers D pivoted to swing in a horizontal plane immediately above the plane of the bottom A; and D*,

a crank-shaft equipped with an actuating arm D, the crank portion of said shaft being connected by rods D with the levers D which serve to actuate the foot-rest.

The frame A of the chair may be of any suitable design and construction. As shown in Fig. 3, the front cross-member A of the frame is provided with slots a in which the slide-bars D move; and extending inwardly from the slots a are narrower slots a through which the rods D work when the foot-restis projected. The cross-member A is equipped with a pivot-block a with which is connected a link or brace forming. a part of the back-adjusting mechanism.

The seat B comprises a frame 6 having slats b and an upholstered portion 6 connected with the upper portion of the frame 6 and having its immediate portion supported on springs which rest upon the slats 6 The slats are received by re cesses b which are formed in the upper edges of the cleats A as shown in Fig. 4:- The upholstering covering is extended over the front edge-piece of the seat-frame; and connected with the lower edge-portion of the relatively narrower front edge-piece is a rearwardly declining member 6 beneath which is afforded a space 6 for the foot-rest in the housed condition thereof.

The foot-rest D comprises a supportingmember d which occupies normally a vertical position, when in the housed condition, as shown in Fig. 1, and a rearwardly declining portion (Z equipped with upholstering d and lying normally beneath the member Z) of the seat. The upholstering d is extended over the upper portion of the front surface of the member 03, and the front surface of the member d is otherwise ornamented or carved, so that when the foot-rest is in the housed position a finished appearance results and the foot-rest forms to all appearances a part of the upholstering of the chair. The foot-rest is short enough (transversely with relation to the chair) to be received between the front legs of the chair, as shown in Figs. 1 and 4. The member (Z extends beneath the slide-bars D by whose front end it is carried, and the intermediate portion of said member is connected by hinges (Z which are applied to the inner surface of the member d and to the upper sur faces of the front portions of the bars D The front ends of the bars D are beveled or inclined forwardly and upwardly, as indicated at d, so that the foot-rest may assume the position shown in Fig. 2, in which position the downward extension of the member (Z beneath the hinges bears against said beveled surfaces. The lower edge of the member (Z is equipped with a cam-member d which is normally received within a loopform cam-member 6Z6 with which the front cross-member A of the main frame is equipped at its central portion, as illustrated in Figs. 1 and 3. The cam or loop (Z declines forwardly somewhat from the lower edge of the frame-member A, as illustrated in Fig. 2. The slide-bars D as has been indicated, project through the slots a in the front cross-member A and the rear portions of said bars lie beneath the cleats A" and rest upon the upper surfaces of the levers D Said bars are provided on their upper surfaces with slots (Z into which project guide-plates or bars d which are applied to the inner surfaces of the cleats A and depend beneath the lower edges of said cleats. The rods D are secured at their front ends to the inner lateral edges of the bars D and have their rear ends connected by pivots cl with the free ends of the levers D Theopposite ends of the levers D are connected by pivots d with the bottom A of the chair-frame. The rods D may be formed of one member having its central portion wrapped about anoifset d in the crank portion of the shaft D The rods diverge forwardly, as shown in Fig. 4, and their front ends are joined by pivots cl with The crank-shaft D? is journaled in the rear portions of the side-members A of the main frame at some distance above the plane of the slide-bars D so that the cranked intermediate portion of the crank-shaft normally depends downwardly and rearwardly some what from the axis of the shaft, as shown in Fig. 1, the dimensions being such that the crank-shaft will be housed between the rear folded position, and will swing forwardly over the rear portion of the bottom A of the chair when the foot-rest is extended, as in: dicated bydotted lines in Fig. 4. The actuating-arm D lies normally in a substantially horizontal position at the exterior of the rear portion of one of the sides A of the frame, where it may conveniently be grasped by the occupant. As indicated in F ig. 4, the actuating arms extend normally forward from the axis of the crank-shaft.

From the foregoing detailed description the operation of the foot-rest will be readily understood. The foot-rest may be projected by swinging the actuating arm or lever D upwardly, and thereby moving the levers D? to the dotted position shown in Fig. 4 and projecting the foot-rest. During the initial movement of the foot-rest in the projecting operation, the cams (Z d operate to tilt the foot-rest from its standing position to the inclined position shown in Fig. 4:, in which position the footboard (Z inclines rearwardly and upwardly in position to comfortably support the feet of the occupant of the chair. During the final portion of the return movement of the foot-rest, which re turn movement is accomplished by actuating the hand-lever D. in the opposite direction, the cams (Z d serve to restore the foot-rest to its original standing position. It will be observed that in this movement the cam 6Z5 enters the loop-form cam cl and impinges against the lower portion of the crossmemher A of the main frame, which therefore serves as a cam-member. The foot-rest may be operated with very slight effort on the part of the occupant of the chair, and is very comfortable and convenient.

The foregoing detailed description has been given for clearn'ess of understanding only, and no undue limitation is to be understood therefrom. 7
