FOOT-REST FOR CHAIRS.

SPECIFICATION forming part of Letters Patent No. 39OA77, dated October 2, 1888.

Application filed October I, 1857. Serial AVG-951,464. (No model.)

To all whom it may concern.-

Be it known that I, JonN HOG-AN, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Foot-Rests for Chairs, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, forming part of this specification.

This improvement relates to devices for securing footrests in various positions; and it consists in certain features of novelty, to be hereinafter described, and then particularly pointed out in the claims.

In the accompanying drawings, Figure I is atop view of the base of a chair-frame, showing the device in folded position. Fig. II is a similar view to Fig. I, except that the frame is extended. Fig. III is a transverse vertical section at III IV, Fig. II. Fig. IV is a similar view to Fig. II, except that the bolts at the point of section are unlocked. Fig. V is a transverse section at V V, Fig. II. Fig. VI is a detail perspective view of one of the catchplates with part of the foot-rest frame. Fig. VII is a detail perspective rear View of one of the brackets with part of one of the slide-bars. Fig. VIII is a detail elevation of the bracket shown in Fig. VII. Fig. IX is a rear elevation of the base-frame of a chair with my improvement applied thereto. Fig. X is a vertical longitudinal section at X XII, Fig. III. Fig. XI is a vertical longitudinal section at XI XV, Fig. II. Fig. XII is a vertical longitudinal section at X XII, Fig. III, except that the foot-rest is shown in different position. Figl XIII is a detail elevation of the front end of the sliding frame. Fig. XIV isa vertical longitudinal section at XI XV,Fig. II, with the catch-plate disengaged from the hook; and Fig. XV is a similar view, except that the foot-rest is in such position that the catch-plate is engaged on the hook. Fig. XVI is a vertical longitudinal section at XVI XVI, Fig. IV. Fig. XVII is a detail perspective view of one corner of the sliding frame, showing the puslrbutton by which the bolts are disengaged. Fig. XVIII is a detail perspective view of one corner of the U-shaped frame to which the foot-rest is pivoted. Fig. XIX is a perspective view of the foot-rest and frames. Fig. XX is a perspective view of one of the quadrants. Fig. XXI is a perspective view of one of the front brackets with part of a slide-bar attached thereto. Fig. XXII is a detail perspective view of the front end of the sliding frame. Fig. XXIII is a perspective view of the Ushaped frame. Fig. XXIV is a detail perspective view showing the catch ing device by which the foot-restis prevented from tilting backward when in usev The chair has fore legs, 1, and hind legs, 2.

3 is the front bar of the seat-frame, 4 the rear bar, and 5 the side bars of the frame.

6 are brackets depending from the front bar 3, and 7 are brackets depending from the rear bar 4:. These brackets are curved inward at the lower ends, and to these ends are attached slidebars 8.

9 are slide plates, sliding backward and forward on the slidebars 8, and carrying at their front ends quadrants 10. The sliding quadrilateral frame has a front bar 11, side bars 12, and bind bars 13. The side bars are pivoted to the quadrants 10 by pivot-pins 14, so that the front end of the frame may be raised or lowered. The plates 9 are connected by a stay-bar, 15.

To secure the frame in any position in which it may be placed,bolts 16 are provided, which work through holes in the side bars 12, and which may each be made to enter any of the bolt-holes 17 in the quadrants. The bolts eX- tend inward to the middle of the rear or hind bar 13 of the frame, and their inner ends are pivoted to the opposite ends of the small lever 18, which turns on a fulcrum-pin, 19, at its middle, the construction being such that the disengagement of one bolt causes the disengagement of the other, and they simultaneously become engaged in the bolt-holes 17 of the quadrant.

20 are lugs upon the bolts, to which are at tached push-pins 21, that pass through curved slots 22 in the quadrants.

23 are spiral springs,surrounding the shanks of the puslrpins and bearing agai ust the heads of the pins and the outer sides of the quadrants, so as to push the heads of the pins outward and cause the bolts 16 to enter and remain in the holes 17. (See Figs. III and IV.)

2% are studs upon the inner faces of the slideplates 9, to arrest the downward movement of the sliding frame upon its pivot 14 when the frame reaches the position shown in Figs. II,

ICO

X, and XIX, the rear ends of the side bars 12 coming in contact with the under sides of the studs for this purpose. At the front ends of the side bars 12 are quadrants 10, constructed like those before described and having similar reference-numbers. To these latter quadrants is pivoted a U-shaped frame having side bars 25 and a front bar 26. The frame 25 26 is pivoted to the quadrants by pivot-pins 27, and otherwise connected thereto by bolts 16, engaging in the holes 17, and operated by the spring push'pins 21, as before described.

The foot-rest has side bars 28 and transverse bars 29 and 30. The side bars 28 are connected by pivot-pins 31 to the rear ends of the side bars 25 of the U-shaped frame. The construction is such that the foot-rest frame may be inverted, and either folded up within the sliding frame, as seen in Figs. I, II, XI, and XlX,or extended, as seen in Figs. XIV and XV,so as to rest upon the front bar 11 of the sliding frame. The inclination of the foot-rest frame is governed by the position of the U-shaped frame, as clearly seen by reference to Figs. XIV and XV. In Fig XIV the U-shaped frame is in the plane of the sliding'fraine and the outer end of the foot-rest frame is elevated, while in Fig. XV the rear ends ot'the U shaped frame and the foot-rest frame are elevated, thus depressing the outer end of the latter frame.

To change the position of the U frame 25 26, the bolts 16 are drawn from the bolt-holes 17 of the quadrants 10 by forcing "in one of the push-pins 21, and on the release of the pushpin the springs 23 will force the bolts into the bolt-holes ofthe quadrant and lock the U frame in position.

32 are locking-plates, which are attached to the side bars 28, so that the edges of the plates project somewhat beyond the inner corners of the bars, so that as the foot-rest is moved forward from the position shown in Fig. XIV to the position shown in Fig. XV the projecting edges of the plate shall be carried beneath hooks 33 upon the bar 11, and so prevent the upward movement of the outer end of the foot-rest.

3& are studs on the front brackets, 6, to limit the forward movement of the sliding frame. (See Fig. XXI.)

I claim as my invention 1. In combination with a chair, bars 8, supported from the frame of the chair, quadrants 10, adapted to slide on the bars 8 and provided with a series of holes, a foot-rest carried by said quadrants, and bolts adapted to engage said series of holes for supporting the foot-rest in various positions, substantially as set forth.

2. The combination of a frame, two sliding quadrants provided with a series of holes, bolts 16, connected together by lever 18, said bolts being adapted to engage said holes, and push-knobs for sliding said bolts, substantially as set forth.

3. The combination of the plates 9, sliding in the base of a chair and having quadrants 10, a frame pivoted to the quadrants and having bolts engaging bolt-holes in the quadrants, and quadrants upon the frame, to which is pivoted a second frame, 25 26, having an invertible foot rest pivoted thereto, and bolts by which the frame 25 26 may be locked to its supporting-quadrants at any inclination, for the purpose set forth.

4. The combination, in a chair or other seat, of the slide-bars 8, the slide-plates 9, working thereon and having quadrants 10, slide-frame pivoted to the quadrants and carrying similar quadrants, to which is pivoted a frame carrying an invertible foot-rest, and the described means of locking the frames to the quadrants, substantially as set forth.

5. The combination, with a chair, of a piv-- JOHN HOG-AN.
