This invention relates to a chiropodist chair and concerns itself with means for adjusting the foot rest and back to any desired angle.

The invention comprises the novel structure and combination of parts hereinafter described and more particularly pointed out and defined in the appended claims.

In the accompanying drawings which illustrate a preferred embodiment of this invention and in which similar reference numerals refer to similar features in the different views:

Figure l is an elevational view of a chiropodist chair involving this invention; p

Figure 2 is an enlarged front elevational View of the leg rest; v

Figure 3 is an enlarged side elevational view taken upon the line IIIIIIof F igure 2;

i 'ure 41:15 an enlarged sectional view taken upon the line IVIV of Figure 3;

Figure 5 is an enlarged sectional view taken upon the line VV of Figure 2;

Figure 6 is an enlarged fragmentary side elevation of the chair illustrating the means for adjusting the back;

Figure 7 is a rear elevational view of the structure shown in Figure 7 Figure 8 is an enlarged sectional view taken upon the line VIIIVIII of Figure 7; and

Figure 9 is an enlarged sectional view taken upon the line IXIX of Figure 8.

As illustrative of this invention, there is shown a chair consisting of a pedestal 1 which supports a seat rail 2 upon which a cushion 3 is supported. From the seat rail, there depends an apron 4 upon which a footboa-rd or rest 5 is supported upon which the occupant is adapted to place his feet when sitting up- 44 right.

A pair of rods or brackets 6 are adjustably secured to the foot board, preferably by slidably extending thru suitable bores therein. These rods have upwardly offset parts 6a upon which vertical bearings 7 are mounted. The bearings 7 are connected by a bridge 8 provided with a groove notch 9 (Figure 5) in which the end of a latch lever 10 is secured. The latch lever 10 is provided with to a circular aperture thru which a rod 11 1928.1 serial, No; "293,903,,

Means are provided for maintaining the back at any suitable angle of inclination.- Thismeansconsistsof arod 25 pivotedat its upper end'to'a casting 26 upon the back of the chair and extending thru an aperture in a locking plate 27 supported in a housing 28 attached to the rear of the seat rail 2. The locking plate 27 is provided with a pair of sockets 28 into which tenons on hand levers 29 extend. These hand levers 29 extend thru the'casing 28 and are provided with upward- 9o ly extending handles 30. A coil spring 31 surrounds the rod 25 and is confined between the top of the casing 28 and locking plate. The casing 28 is provided with a suitable slot 32 thru which the rod 25 extends and in which it may swing. It will be obvious that the spring 31 will normally force the locking plate 27 into frictional engagement with the rod 25 to maintain the same in any predetermined position. When it is desired to adjust the back of the chair, the rod 25 is released by actuating one of the levers 29. This can be quickly done.

In the use of the chair the leg rest 16 may be adjusted thru the sliding brackets 6 to vary its distance from the chair and may he raised and lowered by merely pushing upward upon the lever 10, either by the hand or knee for unlocking the rod 11. This is an exceedingly quick and easy adjustment. The leg rest 16 a may be properly tilted by the link 17. Likewise, the back 21 may be tilted to any desired angle by rotating or operating one of the levers 29 to release the bar 25. This is also a very quick and easy adjustment. It is therefore possible to adjust one to suit the other in order to secure the desired position for the patient or occupant of the chair.

I am aWa-rethat many changes may be made and numerous details of construction may be varied through a Wide range Without departing from the principles of this invention and I, therefore, do not propose limiting the patent granted hereon otherwise than necessitated by the prior art.

I claim as my invention: 7 r

In a chiropodist chair having a foot board, a bracket comprising a bearing having a pair of rods slidably mounted in said foot board, said bearing having spaced apertures and an intermediate aperture, a foot rest having spaced rods extending through said spaced;

apertures and an'intermediate rod extending through said intermediate aperture, said 1ntermediate aperturehaving an enlarged por tion, a spring mounted in said enlarged portion, a friction locking plate having an aperture for receiving said intermediate rod, said bearing having a slot for receiving an end of said plate and a shoulder adjacent said slot for supporting said plate, said spring normally engaging said plate and said plate projecting beyond said bearing for engage ment by the knee of the operator. 7 r

In testimony whereof I have hereunto subscribed my name at Chicago Cook County Illinois.

JOHN R. EMMERT.
