"' Application filed June 16, 1902. Serial No. 111,822 (No model.)
1''0 all whom it may concern:
Be it known that I, WILLIAM A. WYLIE, a
'- citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented-new and useful Immovements in Reclining-Chairs; and I do do} clarethe following to be a full, clear,and exact description of the invention, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specifica-' tion.
My invention relates to chairs of the type that may be adjusted for either upright or reclining positions and that also may be quickly knocked down for shipment; and the invention has reference more particularly to ad justable chairs in which the adjusted positions of the seat and the back may be automatically locked or fixed and alsoautomatically readjusted. The invention also has reference to adjustable chairs having" folding foot-rests.
The objects of the invention are to provide inexpensive, durable, and convenient chairs that may be used with the greatest amount of comfort either with or without foot-rests and that may be either set up or taken apart by an unskilled person and that may be compactly crated for shipment.
My invention consists in an improved form of foot-rest adapted to be folded partly between the front chair-legs and partly beneath the chair-seat.
The invention consists, further, in the parts and in the combination andarrangements of parts, as hereinafter particularly described and claimed. 7
Referring to the drawings,Figure 1 is a front elevation view of a chair in which my improvements areembodied, having cushions thereon, and showing a portion of the footrest frame folded between the front legs thereof; Fig." 2, a longitudinal vertical sectional view showing the back and seat frames, respectively, adjusted for sitting uprightly thereon and the foot-rest extended for use; Fig. 3, a view similar to Fig. 2, but showing the back and seat frames adjusted for reclining positions and the foot-rest folded; Fig. i, a horizontal sectional view as on a line 1 1 in Fi g. 2, showing the top plans of the seat-frame,
main-frame rails, and also the foot-restwhen extended; Fig. 5, a fragmentary detail view showing the manner of pivoting the back and the seat frames together; Fig. 6, a fragmentary detail view showing the manner of pivot-ing the back-frame to the main frame; Fig. 7, a fragmentaryrear View of the main frame and the back-frame, showing several features of construction; Fig. 8, a fragmentary detail view showing porspectively the manner of constructing the main-frame rails and attaching the same to the corner-posts or legs; Fig. 9, a fragmentary side View of portions of the foot-rest; Fig. 10, a fragmentary side view showing the manner of connecting the seatframe to the back-frame; Fig. 11, a perspective view ofa part of the foot-rest frame; Fig. 12, a perspective view of the seat-frame pivotplate, and Fig. 13 a perspective View of the hack-frame pivot-plate.
Similar reference charactersin the several figures of the drawings indicate corresponding parts.
In thedrawings, A A designate the front corner-posts, and B B the rear corner-posts, of the main frame, comprising also the legs and the uprights for supporting the backframe and the arm-rests, the posts being made in any suitable style of ornamentation, preferably of wood; 0 C, the longitudinal or side rails of the main frame, permanently secured to the corner-posts; D D, the transverse or end rails of the main frame, preferably detachably secured to the corner-posts; E E, the arm-rests, permanently attached to the corner-posts; F F, the side'rails of the seatframe; G G, the end railsof the seat-frame; H H, the side bars of the back-frame, constitoting the main parts thereof; a, the seatcushion, and b the back-cushion. The above parts generally are of well-known forms and may be variously modified, according to designs and fancy.
In the practical application of my invention the principal larger parts are usually composed of wood, while smaller parts may suitably be made of metal. The main frame may be jointed together in the usual manner. The seat-frame is relatively flat and the parts suitably jointed together, the forward portion resting on the front rail D and suitably adapted to slide forward and backward thereon,suitableantifrictionalbearingsbeing usually provided. The side rails O C are provided with guides d at the inner sides thereof, preferably inclined.
The back-frame besides the side bars H H comprises a lower cross-bar e and an upper cross-bar fand also suitable slats g. The approximate pivotal points of the back-frame are designated at h in Figs. 2 and 3, the pivots proper being obscured in these views, and in the same figures, i designates the approximate pivotal points of the seat-frame connection with the back-frame. The backframe bars H H are provided with angular pivot-plates I, extending at the rear and the outer sides of the bars and having each a stud-shaftJ extending into a suitable socketbearing K in the upper portions of the rear posts B B. The side rails F F are provided with pivot-plates L, projecting rearwardly therefrom and having each a stud-shaftj at the rear end thereof, extending, inwardly toward the opposing one and into a socketbearing M in the lower portion of either one ofthe back-frame side bars H H, so that the.
rear portion of the seat-frame is pivoted to and supported by the back-frame and. the back-frame is pivoted to and supported by the rear corner-posts. The back-frame bars H H extend below the bar 6 and the seatpivots and are preferably notched at their outer sides oredges adjacently to the cornerposts to clear suitable gravity-locks N N, which are pivoted to the inner sides of the rails C G and having ratchet-teeth 1 and riding on studs 0, attached to the back-frame bars.
The foot-rests comprise a pair of shoulderarms P and P, pivoted at s s to the lower inner sides of the frontposts A A or their leg portions and adapted-to extend up to the front rail D and are connected by a crossbar Q, attached to the free ends thereof against lips 15, below which are stops u. Fore. arms R R are connected to the shoulderarms by pivots 'v and are adapted when in use to bear upon the bar Q as a rest and having shoulders to, adapted to engage the stops to. At the free ends of the arms R R end blocks S are connected thereto by pivots y, and a footboard 8 is attached to the end blocks, extending from'one to the other and may be suitably upholstered. The arms R B have fingers T extending from their outer sides and adapted to slide upon the guides d and support the foot-rest when folded. The end blocks S have lugs U, adapted to engage suitable shoulders at the ends of the arms R R to limit the movements of the blocks and the footboard, the end blocks being so counterpoised as to turn on their pivots when being folded under the seat-frame.
In order to readily knock down the chairframe, the rails D D have grooves 2 cut longitudiually at the ends of the inner sides thereof and cross-grooves 3 intersecting thegrooves 2. Between the ends of the rails and the grooves 3 blocks 4 are secured to the rails, extending across the grooves 2. Dowels 5 extend from the endsof the rails into suitable holes in the corner-posts. Screw-bolts 6 extend through the corner-posts, so as to enter the grooves 2, and nuts 7 may be attached to the bolts and tightened in the grooves 3, the bolt-heads being at the outer sides of the posts. This construction is also adapted to permit of the bolts being first inserted in the grooves 2 and then projected through the corner-posts, the nuts being then placed at the outer sides of the posts. In either case the nut or the bolt-head may bear partly against the block 4.
In using the foot-rest the arms are to be drawn forward until they are stopped in the positions indicated in Fig. 2. To fold the rest, the fore arms are to be pushed over toward the chair until arrested by the stopsu and w, when the arms P P are to be lifted and pushed back to their places, as shown in Fig. 3, the fingers T automatically engaging the guides d, and thereby supporting the extremities of the rest between the rails of the main frame out of sight, or nearly so.
When knocking down the chair, the bolts 6 may first be slackened somewhat, and the posts may then be drawnaway partly from the transverse rails, when the back-frame will be released from itspivots, and the seatframe may be folded against the back-frame or it may be disconnected therefrom. The arms P P may then be disconnected from their pivots. Then the bolts 6 may be entirely disconnected, so that the transverse rails may be removed, leaving the two entire sides of the main frame intact.
Having thus described my invention, what I claim is- 1. An adjustable chair including a main frame havinga front rail and front supporting-legs, a pair of shoulder-arms having each at one end thereof a lateral lip and pivoted at its opposite end to the lower portion-of a front leg, a cross-bar attached to the lips of'the shoulder-arms, fore arms pivoted to the shoulder-arms between the pivoted ends thereof and the cross-bar and adapted to bear upon the lips, stops connected with the arms limiting the rearward movements of the fore arms relative to the shoulder-arms, and a footboard operatively connected with the. fore arms.
