FOLDING CHAIR-commons. .y

SPECIFICATION forming part of Letters Patent No. 544,535, dated August 13, 1895.

Application led August 24, 1893.

To @ZZ whom it may concern:

Be it known that I, CHARLES O. HENNIG, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Folding Chair-Commodes, of which the following is a specification.

My invention consists of an improved folding commode-chair, the invention comprising certain details of construction fully set forth and specifically claimed hereinafter.

In the accompanying drawings, Figure 1 is a sectional view of my improved folding commode-chair showing the same extended. Fig. 2 is a sectional view showing the chair folded, and Fig. 3 is an enlarged section illustrating the means employed for connecting the receiving-vessel to the seat of'the chair and for closing the said vessel when the same is not 1n use.

The chair comprises a seat A, mounted upon opposite pairs of legs B B', which are pivoted together by means of a central rod a., each leg B being likewise pivoted, by means of a rod l), to the rear of the seat, while the legs B carry at their upper ends a transverse rod d, which engages with the hooked front end f of the seat when the chair is extended. When the front end of theseat is lifted, however, so as to free said hooked end f from engagement with the rod d, the legs B B are at liberty to fold together, as shown in Fig. 2.

Hinged to the seat A, near the back edge of the same, is a back D, which is connected by arms F to the legs B of the supporting-` frame, so that the back D is automatically are extended or contracted.

To the seat A is pivoted a lid G, cushioned or upholstered in any suitable manner, this lid serving to cover the opening in the seat, to which is fitted the receiving-vessel J, the sides of which are composed of rubber or other waterproof and flexible material, the bottom of the vessel being, however, comparatively rigid, so that when the chair is folded the vessel will be caused to collapse in contact 0f said comparatively-rigid bottom with the pivotal cross-bar a. Around the edge of the opening in the seat A extends a double rim or flange g ofsheet metal, and between the inner and outer portions of` this flange is securely confined the upper edge of the vessel J, as shown in Fig. 3. Theinner Serial No. 48 31955. (No model.)

iiange of the rim is threaded for the reception of a rib or flange upon a sheet-metal cap or cover K, having a flexible or elastic rim i, which, when the cover is screwed down into place, bears firmly against the rim G and serves to make a tight joint, which will prevent the escape of any odor from the vessel J. The rim g is secured in place by means of turn-buttons M, or other other equivalent movable fastenings, so that the vessel, with its rim, can be readily removed from the seat for the purpose of emptying and cleansing the same. y

My invention provides a compact and convenient form of commode-chair which occupies very little space when stored away or while it is being carried from place to place,

and yet it can be almost instantly extended and rendered available for use when required.

Having thus described my invention, I claim and desire to secure by Letters Patent- 1. The combination in a commode chair, of the seat having a receiving vessel 'and a hooked front end, the supporting structure consisting of pivoted legs hung to the seat at the rear end of the same and having a locking bar engaging with the front hooked end, a back pivoted to the seat so as to fold forwardly onto the same, and arms connecting the lower portion ofthe back to the legs of the supporting structure, whereby,`when the hooked front end of the seat is lifted out of engagement with the front bar of the legs, all parts of the chair can be simultaneously folded, substantially as specified.

2. The combination of the seat having an opening therein, the receiving vessel of Iiexible material, and the rim or flange consisting of a folded strip of metal between the oppo site folds of which the upper portion of the vessel is confined, the portion of the folded strip beyond the vessel being bent outwardly and forming a ange wherebyithe vessel is supported upon the seat, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
