WILLIAM :JAMES ARMSTRONG, OF PATERSON, NEW JERSEY.
CHAIR WITH EXTENSIBLE FOOT-BEST.
Specification of Letters Patent.
Patented Oct. 22, 1907.
Application filed September 15, 1906. Serial No. 334,719.
To all whom it may concern:
Be it known that I, \VILLIAM Linus ARMSTRONG, a subject of King Edward VII of Great Britain, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Chairs with Extensible Foot-Rests, of which the following is a specification, reference being had therein to the accompanying drawing.
The object of my invention is to produce a chair capable of adjustment so as to enable the occupant to enjoy the comfort derived from placing the body in a desired position that will stimulate a healthy circulation of the blood which is conducive to longevity The invention consists of an adjustable foot-rest capable of a horizontal as well as a vertical adjustment in relation to the seat of the chair to which it is attached.
The invention may be attached to a chair having either a movable back or seat and enables the occiipant to support the limbs at the point and elevation desired to relieve fatigue and induce the rest and circulation required for the purpose.
In the accompanying drawings similar letters of reference indicate like parts.
Figure l is a section through the middle of a chair showing the improvement which is the subject of this invention. Fig. 2 is a view showing a section of the improved chair on the line AA in Fig. 1, and Fig. 3 is an. enlarged sectional view of the adjusting device.
In the drawings, 1 is the frame of the chair; 2, the
legs; 3, the upholstering; and 4, the legs of the movable rest; 5 and 6 the upholstered portions of the foot rest.
The movable foot-rest is secured to the rod '7-* which is slidably connected with the inner and outer sleeves 8 and 9--- h old by the support -10- pivotally secured to the frame of the chair and which is adjusted by the spring -1land thumb-screw 12. The inner end of the outer sleeve 9 may be slightly raised or lowered owing to, and to compensate for, any unevenness of the floor and the spring .11 may be adjusted by a manipulation of the thumb -screw 12 so as to form a cushion for the inner end of said sleeve. The spring therefore co-acting with the function of the hanging lever-support 10 form a compensating device that obviates the objectionable features resulting from a connection between the chair proper and the movable foot-rest portion, were the sliding sleeve and rod and outer sleeve rigidly held in a horizontal plane.
The foot-rest is provided with a rack portion -13 which is engaged by the lever-pawl 14, the end -15 being operated by hand or foot to release the rack -13- when desired. Said lever-pawl is supported on the shaft l6 mounted in bearings 18.
The upper end of the pawl-lever is held in engagement with the rack-portion 'l3 by the spring 17.
It is obvious that the legs may be held at the eleva tion desired which may vary according to conditions and circumstances.
My invention may be applied to a Morris or other chair.
With this description of my invention, what I claim as new and desire to secure by Letters-Patent, is
movable i'oohrest portion, a pivotal hanger supporting said rod and sleeves beneath the chair and a spring to adjust the plane in which the rod and sleeves lie, substan tiully as set forth.
In testimony whereof I :ifiix my signature in presence or two witnesses.
\VILLIAM JAMES ARMSTRONG.
