rThis invention relates to a chiropody chair,

and has for its obect to provide a chiropody chair having improved leg` rests which are independently adjustable, and which embrace a novel means of support and a latching device, thereby permitting the. leg restsv to be quickly and easily adjusted and latched in any position that may be required by varied conditions of use. n

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

As illustrative of this invention, therev is shown in Figure 1 an adjustable chairvconsisting of a pedestal 1 which supportsa seat rail2 uponwhich a cushion 43 is supported. Pivotallyl secured to the seat rail is a depending frame 4 whichl carries `an apron 5 `upon which a pair of? independently adjustable leg rests 6 are supported. By vsupporting each leg of an occupant upon an independent leg rest, it is apparent that each leg rest ma be made relatively narrow and also adjuste relative to the other one, thereby permitting the operator to so adjust each leg rest thatr his work may be performed with a minimum of int-erference. The lower portionoftheframe 4 carries a footboard or rest 7 which is adapted for supporting the feet of an oci cupant when sitting upright in thechair.

TheA apron isvindented or dished as atjS f to receive apany or open ended trough orl mounting 9 which is hingedly supportedfrom lugslO lprovided at the upper end of the apron.'` n Ik 1 y Since each'leg rest is similar in construction; only one of themy will be described herein. `A bearing bracket 11, secured t0 the underside .of the trough i, and extending through an aperture 12 in the apron, provides a connection in which the upper end of arod 13 is pivo'ted. This rod extends through a cored block 14 having its ends trunnioned in lugs 15 which are integrally rformed on a plate member: 16 which is kixedly secured lto the underside of the apron. Extending through the bloclr 14 isa rectangular aper-v ture 17 through which the rod`13 passes. An end wall Vof* this aperture is providedwith a groove or notch`18in which the end of a latch leverf19kV isoscillatably secured. This lever.`

isprovided with a circular aperture through which the rod i 13 extends. Longitudinal ,adjustment ofthe rod relative tothe block 14 is effected by means .of the latch lever n 19 which is yforced into lfrictional engagement with s'aidrod by a coilfspring 20, whichl is seated in they wall ofthe rectangular aperture 17;v It is-obvious that'the" rod may be easilyl releasedy by moving thelat'ch lever i against the pressure of the coiledspring. To

facilitate the releasingof the latchlever, a

like i pin 2l is supported in one of the trunnions of the block la for longitudinal movement. rIhis pin is beveled on its inner end for slidably engaging a. bevel 22 on the free end of the latch lever. A coiled spring 23 normally forces the pin outwardly against a shoulder Qsl which serves as a limit stop. if the pin is pushed inwardly against the pressure of spring Q3, the beveled end thereofV will move into engagement with the bevel 22 and force the latch lever to one side against the pressure of spring 20, thereby releasing the rod 13. Upon releasing the pin, it will be forced outwardly by the spring Q3 and the latch lever will frictionally engage the rod as before.

A padded member 25 is slidably supported for longitiuilinal adjustment upon a stationary guide rod Q6 which is secured to the trough 9. rThe stationary guide rod extends through a cored casting 27 which is secured to the underside of the padded member. This casting is provided with a notch or groove 28 in which one end of a latch lever 29 is oscillatably secured. VlShe latch lever which is provided with a circular aperture through which the rod 26 passes is forced into frictional engagement with said rod by means of a coiled spring 30 which is seated in a socket 31 in the casting 27, thereby releasably latching the padded member in place. A release rod S2 is provided with a handle 33, which, for convenience, is placed at the forward end of the padded member where it will be within easy reach of the operator. The inner end of this rod is connected to the free end of the latch lever in such a manner that, when the operator pulls the handle 33, the latch lever is moved out of engagement with the rod and the padded member is then free to be moved to a new position, if desired.

A further reiinement is preferably provided for operating the release pin 2l, which consists of an arm 35 which is pivoted at its upper end adjacent the frame 4l and carries a treadle 36 at its lower end adjacent the foot rest 7. The treadle 36 is normally held in a raised position by means of a coiled spring 37 which is supported in a bracket 88 in such a manner that it bears against the underside of the arm for forcingl it upwardly, as shown in Figure 9. Adjacent the outer end of the pin 2l a projection is provided on the arm 35 having an upwardly and inwardly extending beveled surface 39 which bears against the end of the pin and forces it inwardly when the arm 35 is moved downwardly. ItA will thus be seen that the latch lever 19 lmay be conveniently released by a downward pressure on the treadle 3G.

This invention, therefore, provides a chiropody chair having a pair of leg rests which may be quickly and easily adjusted and latched in any angular position as necessi` Therefore,

tated by varied conditions of use. The padded portion of the leg rests may quickly and easily be moved outwardly or inwardly by the operator and latched in the position desired. A novel means is also provided for quickly and easily releasing either of the leg rests to permit of either an angular or a longitudinal adjustment.

I am aware that 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 purpose limiting the patent granted hereon otherwise than necessitated by the prior art.

I claim as my invention:

l. In a chiropody chair, an apron member having a pair of depressed portions, a pair of leg rests pivoted to said member and adapted for entering said depressed portions, a rod pivoted to each leg rest and extending through said apron member, latching mechanism for cach rod including a slidable plunger, and a foot pedal pivoted to said apron member for operating each plunger, said plunger and foot pedal havin inclined coacting surfaces.

2. In a chiropody chair, an apron member, a leg rest pivoted to said member, a rod pivoted to the leg rest and extending through said member, latching mechanism for said rod including a slidable plunge said plunger having a beveled head. a foot pedal pivoted to said member, and having an inclined surface for coaction with said plunger.

3. In a chiropody chair, an apron having a dished portion, a pan having means pivoted to said apron and swingable into said dished portion, a rod carried by said pan, a padded member slidable on said rod, and releasahle latching member for securing said member to said rod in any desired position.

l. In a chair having an apron with dished portions, a mounting hinged in each dished portion, a rod carried by each mounting, a pad adjustably mounted on each rod for longitudinal movement and means for .independently elevating said mountings with respect to said apron.

5. In a chair, a chair frame including a depending swingable apron thereon, a pair of mountings independently and angularly adjustably mounted on the apron, pads slidably mounted in said mountings, and means for connecting said mountings to said apron for causing them to be swingable together with said apron as a single unit. Y

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

Illinois.
