ADJUSTABLE CHAIR.

Specification of Letters Patent.

To all whom if may concern:

Be it known that I, JERBOLD F. lVALTon, a citizen of the United States, the city' of Sturgis, county of St. Joseph, Stateof Michigan, have invented .certain new and useful Improvements in Adjustable Chairs, of which the following is a specification.

This invention relates to improvements in adjustable chairs.

The main objects of this invention are: First, to provide an improved adjustable chair having an adjustable foot-rest, which, when collapsed, is inconspicuous, the chair having a complete finished appearance. SQCOIICLiO providejin achair a collapsible foot-rest structure, adapted also to serve as a rack for books, papers, or the like. Third, to provide inan adjustable chair an improved foot-rest, which is simple and economical in structure, is very strong and durable and easily ad justed.

Further objects,

and objects relating to structural details,

will definitely appear from the detailed description to follow.

objects ofmy invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims. v a A structure which is a preferred embodiment of my invention is clearly illustrated in theaccompanying drawing, forming a part of this specification, in which:

Figure 1 is an inverted view of a structure embodying the features of' my invention. Fig. 2 is a. vertical section, taken on a line corresponding to line 22 of Fig. 1. Fig. '3 is a vertical section, taken on a line corresponding to line 33 of Fig; l, the foot-rest being extended; Fig. 4 is a detail perspective view with the foot-rest extended. Fig. 5 is a detail vertical section, showing the arrangement of one of the supporting brackets 18 for one of the slide ways 16. Fig. 6 is a detail perspective. of the foot card in itsrerected I accomplish the is an enlarged detail perspective showing means for retaining the supporting. arm 10 in the back.

residing at.

and, at the same time,

position, showing the. structure of the foot-board support. Fig. 7

similar reference char'-- several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring consists of the rear posts 1 and front posts 2, which-arc-extended to form the legs of the chair. On the upper ends of the posts are able side frame pieces 4 and front and rear pieces 5 and 6, respectively. The frame is also provided. with a horizontally-disposed bottom piece' 7, on which the adjusting mechanism for the adjustable back is mounted. This back consists of the side pieces 8 and cross pieces 9. The back is suitably pivoted, the pivots being such as'a-re illustrated in my application for patent filed March 29, 1909, Serial NO..486,4:70, and are noth l e illustrated.

The supporting ranged vertically through the cross pieces,- as illustrated, and is provided witha link 11 on its lower end, which projects. forwardly under the chair and is engaged by the adjusting rod 12. return spring 13 for the back is provided. This adjusting mechanism formsno part of my present invention, and I do not, therefore, illustrate and describe the same in further detail herein.

To retain the arm 10 in position in the back I provide an angled clip 14, shown in detail in Fig. 7, which is slotted or notched. to receive the rod, the'rod being provided with a laterally-projecting pin 15, so that, by giving the rod a quarter turn, the pin swings over and" engages the clip. This provides a very simple and eflective means for securing the arm.

bars 17 are formed of sheet metal, channel'- shaped in cross section. These slide ways are secured'by their upper arms to the lower edges of the front and rear frame cross pieces 5 and 6. The slide ways, are supported and braced by .the' brackets 18. These brackets are in the shape of a; double angle, the upper arm of the-upper angle, in-g'secu-red to the inner sides pfihe fra'me pieces 4,and their 110 er angles b'eing adapt;-

slide-ways' are, by this means, efiectivelylf braced. and supported. The brackets are.

to the drawing, the chair frame arms The posts are connected by 'suit- The slide-ways 16 for the foot-rest slide ids arranged at the front where the heavy strains occur when the foot-rest is extended. v

The front cross piece 19 is iiiortiscdonto the ends of the slide bars, and, when the foot-rest is collapsed, slides between the front legs of the chair and under the front cross piece 5, forming, in appearance, a continuation of the same. The cross bars are provided with a rear cross piece 20 of metal, secured to their under edges and having an offset 21 therein to accommodate the link of the back adjusting means.

The foot-rest 22 is mounted on a bail-like support 23, the arms of the support being provided with laterally-turned journals 24, which are journaled in the slide bars, so that the foot-rest may be collapsed between the same, and, when erected, the support will rest upon the front cross piece 19. The arms of the support are provided with ofi'set stops 25 for the foot-rest. The foot-rest is secured upon the'horizontal portion ofthe support by means of the clips 26. A rack 27 for papers, books or other articles, is provided, the rack illustrated being basket-like in form,havingside and rear walls but no front wall, so that the foot-board can collapse be- The rear wall ofthe rack is notched or cut away at 28, to accommodate the adjusting mechanism' forthe back. "With this arrangement of the parts, I secure a foot-rest which is simple in structure, and, at the same time, is strong and rigid when extended. Further, itis easily operated and when collapsed, does not in any way injure the appearance of the chair.

I have illustrated and described my improvements in detail in one of tlie forms in which I have embodied the same, the form illustrated being the form at present preferred b me, I do not illustrate or describe the mo ifications herein, as I believe such modifications will be obvious to those skilled in the'art' to-which this invention relates.

Having thus. described my inventiomwhat I claim as new and desire to secure by Letters Patent is -1. In an adjustable chair, the combination with the frame comprising horizontally-disposed, bottom, side,- front and rear frame. 'pleces; oppositely facing channel shaped slide ways secured by their upper arms to the lower edges of said front and rear frame pieces; corner braces in said frame; doubleangled brackets secured by the upper arms of their upper angles to said frame side pieces, the lower angles of said brackets bemg disposed beneath said slide ways and their intermediate parts being disposed beneath said braces; slide bars arrangedin said ways; a foot-rest; and a bail-like support for said foot rest pivoted to said slide bars and, disposed to rest on'said front cross piece thereof when erected and to collapse onto a suit-able support, the sides of said bail sup portbeing provided with offsets adapted to serve as stops for said foot-rest, said footrest being pivotally secured to the central pprtion of said bail, as described.

. 2. In an adjustable chair, the combination with the frame comprising horizontally-disposed bottom, side, front and rear frame pieces oppositely facing channel shapedslide ways secured by their up er arms to the lower edges of said front an. rear frame pieces; corner braces in said frame; double angled brackets secured by the u per arms of their upper angles to said rame side pieces, the lower angles of said brackets being disposed beneath said slide ways and their intermediate parts being disposed beneath said braces; slide bars arranged in said Ways; and a foot-rest carried by said bars andpivoted to collapse between said bars, as described.

3. In an adjust-able chair, the combination with the frame comprising horizontally-disposed bottom, side, front and rear frame pieces; oppositely facing channel -'shaped said foot-rest,'sa1d f00t-rest being pivotally secured to the central portion of said bail, as described.

In witness whereof, I have hereunto set my hand and seal in the presence of two witnesses'.
