CONVERTIBLE CHAIR.

To all whom z't may cohcem:

Be it known that I, LISA E. ERBEAU, a

city and county of Camden, State of New Jersey, have invented a new and useful Convertible Chair, of which the following is aA specification.

y invention consists of a chair that is convertible to various uses, more particularly for children, such as a low or high chair or for toilet use, and may be foldedA in compact form for transportation, carried by hand, packed, stored, etc., the construction being hereinafter described and the novel features thereof pointed out in the claims.

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be va-l ried, and so it is to be understood that the invention is not limited to the specific details shown and described, as long as they are within the spirit or scope of the claims.

Figure 1 represents a perspective view of a childs chair embodying my invention.

Figs. 2 and" 3 represent perspectivel views in reduced scale ofgthe chair in partly folded condition.

Fig. Il represents a perspective view of the chair in completely folded condition.

Fig. 5 represents a perspective view of the chair in use with a water closet bowl.

Fig. 6 represents a side elevation of the chair on a reduced'scale as converted into a high chair.

Fig. 7 represents a vertical section of portions of Fig. 6 on anenlarged scale.

Fig. 8 represents a transverse section on line 8 8 Fig. 7.

mechanism for lookin the side arms preventing folding thereo Similar numerals of reference indicate corresponding parts in the figures. Referring to the drawings,

1 designates the seat of the chair, the Same having therein an opening which may be placed on a chamber pot or the bowl of a water closet when the chair is placed over the same, said opening having a cover 2 for closing purposes.

3 designates the back of the chair which is hinged at the bottom to the rear of the seat and 4 designates a supplemental back which is stationarily connected with said rear and adapted to support said hinged back, and when the latter is lowered or folded provides -another back for the chair.

same being hinged to the sides of the seat and are adapted when the back 4 is in folded condition to be folded upon the same.

6 designates the legs of the chair, the same being hinged to the underside of the seat as at v7, whereby they may be folded upwardly against the underside of the seat. In order to retain said legs in operative condition as shown in Figs. l and 6, I provide the brace or stretcher 8 com osed of opposite bars or pieces which are hin ed at their outer ends to .said legs as at 9. I'he innerends of said legs are adapted to be connected by the sliding sleeve 10 which embrace said ends and so retain the brace against separation, but when said sleeve is moved tothe right or left, the ends of the members of the brace are uncovered and disconnected and so the bars 'or pieces may be folded on the legs and the latter folded with the' same against the underside of the seat, it thus being seen that the chair as thus constituted may be compactly folded, convenient for purposes of carrying by hand, transportation, packing, storage etc.

`When the legs 6 are in operative positions, the chair forms what I term a low chair, but in order to convert it into a high chair I pro- Fig. 17 representsa side elevation thereof,

loo

vide the bottom of said legs with sockets l1 Y legs 6, thus raisin the seat 1 and rendering the. chair serviceab e as a high chair. These sockets are hollow members securedto the legs and have closing walls at top, see said Fig. 7 so asto limit the upward movement of the legs by the abutment of the top edges of said legs against said walls and so sustain said legs in a firm and steady manner. When the chair is at normal height as in Fig. 1, the sockets 11 being on the sides of the lower ends of the legs 6, form feet on which said legs are supported-in addition to 'the legs themselves on a floor, and provide broad bases as feet for steadying said legs and consequentlf the chair and form reinforcements for the' ower ends of said main legs 6 and avoid boring said ends to receive the extension legs.

The chair is provided with the tray 13 which is journaled by the dowels 13x with 4the arm rests 5, whereby it may be raised and loweredas usual in such cases and serve Ato prevent the arms from closing in front.

In order to lock said arm rests at their rear portions and prevent inward motion thereat there are connectedwith the sides of the supplemental back 4, the chains or flexible members 14 with which are connected the .balls or heads 15 the latter being adapted to engage the bifurcated catches 16 on the arm seat, a back hinged thereto, a stationary back rests 5 of the chair, it being noticed that the flexible members 14 enter said catches and the balls or heads 15 drop in front of the lat- 'ter and so retain said members in position and connect the arm rests with the back preventing the former from im roper foldmg, this being particularly serviceable when the hinged back 3 is in folded position on the seat 1. v

When the ballsor heads and flexible members are raised from the catches 16 and so released from the same, the arm rests are unlocked. from the back 3 and theyv may be folded as hereinbefore stated.

In order to connect the chair with a chamber pot or water closet bowl and prevent it from slipping therefrom there are connected:` with the underside of the seat the resilientV jaws 17 of elbow form and adapted to be spread apart so as to be fitted over the flange of the p ot or bowl and then springtoward each other closed on the sam'e, thus retaining the chair in position while it is in use.

In order to operate said jaws 17 so as to separate or open them there are connected with the -same the rods 18 forming handles vent inward motion which are slidingly mounted inears 19 on the underside of the seat and accessible at the sidesofthe latter, as'most plainly shown in Figs. 9, 11 and 12.

The rear of the seat has connected with it the hook-likemember 20 which may be enaged with the wall of the top of the chamger pot or bowlor seat portion of the latter as means for additionally connecting the chair with said ot, or bowl or seat portion.

Having thus escribed my invention what I claim as new and desire to secure by Letters Patent, is

1. A chair of the character stated, `comprising a seat, a back hinged thereto, a supplemental back fixed to the rear of said seat,

side arms hinged to the sides of the seat, and means connecting the rear ends of said arms the upward motions of the-latter, said socket pieces primarily forming broad bases and reinforces for the lower ends of said main legs. 3. In a chair of the character stated, a

adapted tosupport the former 'in upright Y plemental back fixed to the rear of said seat,

side arms hingedto the sides of the seat,

means connectmg the rear ends'of said arms with the ends of the top member of the 'lastnamed back, and means on the supplemental back engageable with the arms of the chair vto lock the rear ends of said arms and preof the latter. i
