Specification of Letters Patent.

Patented Oct. 30, 1906.

Application filed February 6. 1905. se an No. 244,408.

To all-whom it may concern:

Be it known that I, J OHN FLINDALL, a citizen of the United States, residing at Chicago, in the county of Cook and State of IlliIlOlS, have invented certain new and useful Improvements in Chairs; and I do hereby deits horizontal fposition.

clare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in chairs, and more particularly to the Morris chair type; and the object inview is the facilitating of the adjustment of the parts of the chair to various positions.

A further object is the provision of the movably-mounted foot-rest adapted to be shifted for facilitating approach to the chair.

With these and further objects in view the invention comprises certain novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 represents a transverse vertical section through a chair, parts being illustrated in elevation and the seat-frame being shown in Fig. 2 represents a similar view' 0 the same with the seat-frame being pivoted to an inclined position. Fig. 3 represents a transverse vertical section through the parts as seen in Fig. 1, parts being illustrated in elevation. Fig. 4 represents a top plan view of the chair, arts being broken away and the cushion being omitte Referring to the drawings by numerals, 1 1 indicate any suitably-constructed sides of a chair, said sides being connected by crossbars 2 2, the sides and cross-bars forming a chair-frame. A rod 3 extends transversely across and connects the sides 2, and upon said rod 3 is pivotally mounted the seatframe 4, said frame being provided with rearwardly-exte'nding segmental plates 5, which are provided with the usual notched slots 6, a rod 7 extending transversely of the chair and projecting through the slots 6 and being en gaged at each end by a lever 8, each lever 8 extending to and being pivotally connected with the respective side of the back 9. Each lever 8 conslsts, preferably, of a strap of suitable material, preferably metal, extending past its pivotal connection with the back 9 and being twisted into a handle 10. The back 9 is pivoted, as at 11, to the seat-frame 4 in position for being swung back and forth from a vertical to an inclined position, said back being designed to be supported in its given position by the levers 8 and rod 7 engaging the respective notches of the slot 6. Pivoted to the sides '1 and extending across the space between the same is a bail-shaped pawl 12, said pawl being engaged by spring 13 for normally retaining the same in the extreme of its forward movement, a detent 14 projecting from one of the sides 1 in the path of movement of the awl 12 for limiting the forward movement t ereof. The horizontal cross-bar of the pawl 12 is designed normally to lie beneath and to su port the rear end of the bottom frame 4, ti? frame resting upon the front cross-bar 2. The bailpawl 12 thus normally revents movement of the seat-frame 4 upon 1ts pivot 3; but in order to make possible such movement of the seat-frame I provide a longitudinally-movable rod 15, projecting from the front of the chair and extending rearwardly near one of the sides 1 to a point contiguous to the pawl 12, the rear end of the rod 15 e front end of said curving downwardly, as at 16, past the pawl 12, so that when said rod 15 is moved rearwardly the curved end 16 will engage the pawl 12 and move the same against the pres' sure of spring 13 out of contact with the seatframe 4, so that said frame will be free to swing u on its pivot. gree of t e swing of the seat-frame 4 I preferably provide any suitable stop 17, projecting from one of the sides upon which the rear end of the frame 4 may rest when ivoted to the position indicated in Fig. 2. o restore the parts to their normal position, it is necessary to de ress the front end of the frame 4 to lift up t e rear end thereof, whereupon the bailed pawl 12 will swing forwardly under the action of spring 13 until the same contacts with the stop 14, whereupon said pawl-Will be in position for supporting the rear end of the frame 4.

In conjunction with the chair as above described I propose to employ a foot-rest con- For limiting the dedinal tongues 23, slidingly engaging grooves 24 24, formed in the rear end of the arms of the bifurcation of slide 18. The rear ends of said arms are also formed with shoulders 25 25, designed to contact with similar shoulders 26 26, carried by the front end of the guiding strip 21 when the slide is at the outer extreme of its movement, whereby said slide may be prevented from being entirely withdrawn from the bottom of the chair.

In operation it is to be observed that when the slide 18 has been withdrawn to the position indicated in dotted lines in Fig. 1 the same is free to be swung laterally to either side, as may be desired, the lateral position of the slide being indicated in dotted lines in Fig. 4. The slide 18 of course swings upon the pivot 22, the guiding-strip 21 swinging laterally to the required extent for accommodating the lateral movement of the slide 18. The lateral swinging of the slide 18 is designed to facilitate approach to the chair without necessitating returning of the slide to its position within the guides 19.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a chair, the combination with a frame, of a seat pivoted thereto, a stop movably mounted beneath said seat and designed to sustain the same against pivotal movement and a sliding rod projecting from said frame and extending to a point contiguous to said stop for moving the stop out of contact with the seat.

2. In a chair, the combination with a frame, of a seat pivoted thereto, a stop movably mounted beneath said seat and designed to sustain the same against pivotal movement, and a longitudinal, movable rod provided with a curved end, capable of moving the stop out of contact with said seat.

3. In a chair, the combination with a,

frame, of a seat carried by said frame, of a bail-pawl pivotally mounted upon said frame and adapted to be swung beneath said seat for preventing movement thereof, and a longitudinal, movable rod carried by said seat and capable of moving said pawl from beneath said seat.

4. In a chair, the combination with a frame, of a movable seat carried by said frame, of a pawl adapted to swing beneath and extended transversely across said seat for securing the same in an elevated position, and longitudinally-movable means carried by said seat and capable of engaging said pawl to move the same from beneath said seat.

5. In a chair, the combination with a frame, of a pivotally-mounted seat carried by said frame, of a bail-pawl pivotally mounted upon said frame and adapted to swing beneath said seat, a flexible member secured to said pawl at one end and to said frame at its opposite end, and a longitudinally-movable rod provided with a curved, inner end carried by said seat and capable of engaging said pawl for moving the same from beneath said seat.

6. In a chair, the combination with a frame, of a pivotally-mounted seat carried by said frame, notched, segmental members carried by said seat, a movable back carried by said seat, levers pivoted upon the sides of said back, a transverse bar connecting said levers and adapted to engage the notched portion. of said segmental members for securing said back in an adjusted position, a pivotally-mounted member carried. by said. frame to one side of said seat and adapted to be swung beneath the seat for securing the same in a fixed position, and means carried entirely by said seat and being capable of moving said pivotally-mounted member for permitting of said seat to be swung to an inclined position.

In testimony whereof I hereunto aflix my signature in presence of two witnesses.

JOHN FLINDALL.
