taining a water-tight joint between the walls of the compartments.

In devices of this character, the walls are preferably made of sheet metal and for the sake of economy and transportation and handling they must usually be assembled on.

the job so that it is necessary that the parts be so constructed as to permit application of the finishing coating particularly where it is a vitreous enamel coating prior to the assembly. It must also be possible then to assemble the walls into a completed compartment without injuring this coating or exposing the bare metal which would cause serious deterioration due to corrosion. Considerable difliculty has been encountered in obtaining a construction that would permit of assembling the completely coated shower bath compartments so as to obtain a substantially watertight joint and still maintain the exposed interior surfaces of the compartments in smooth undamaged condition.

The present type of construction as illustrated in the accompanying drawings has been found to be particularly applicable to obtaining the results desired.

In the drawings- Fig. 1 is a vertical sectional view taken through a shower stall embodying my invention' Fig. 2 is a fragmentary perspective broken away to illustrate more clearly the construction;

Fig. 3 is a top plan view of one of the corners with parts thereof in section showing the manner of securing certain elements to-.

gether;

Fig.4 is a horizontal sectional view showing the application of my invention to a battery of shower stalls installed side by side; and

Fig. 5 is an enlarged sectional view of one of the joints in Fig. 4.

Referring now in detail to the drawings, the shower .stall is in general made up of the base or receptor 6-which I construct with an upstanding rim 7 having embedded therein the flange member 8 within which the vertical compartment walls such as 9 and 10 are adapted to fit. The wall elements 9 and 10 are of sheet metal and preferably coated with some coating capable of resisting the tendency to corrode under the influence of the water used in the compartment. The best coating for this purpose in the present use is a vitreous enamel coatingyvhich must be applied at a high heat and which when cooled is comparatively brittle and easy to chip if subjected to sudden blows or stresses.

Referring now to Figs. 2 and 3, I will describe specifically the construction of the joint between the side and back walls that I have found to be particularly efiicient in preported to the installation location. The back wall 9 is as shown bent forwardly adjacent its vertical edge at 11 at an angle of about 45 degrees to the plane of the back Wall and ex tended over in this direction for an inch or tWo when it is again bent as at 12 to extend substantially parallel to the main body portion 9. The free edge 13 is then bent back to extend at right angles to the main portion 9 to a point substantially aligning with the front surface of the back wall. It will be noted that this formation of the back Wall gives a smooth exposed surface to the interior of the compartment and at the same time provides at 14 a relatively wide fiat surface upon which pressure may be applied to force the back wall into assembly with the side wall 10 as will now be described.

The side wall 10 is bent at 15 so asto extend the portion 16 in the plane of the ultimate position of the back wall 9, and the width of the portion 16 is preferably such as to substantially overlap the space between the portions 11 and 13 of the wall 9 although, of course, 16 may be narrowed without deterioration from the advantages of the structure. The portion 16 has secured thereto a long strip 17 which may be secured by any suitable means such as by spot welding or by means of a screw 18. In case the material is vitreous enamel, I prefer to use the method shown in Fig. 3 for securing the member 17 to the portion 16. This member 17 has a bend at 19 to extend the portion 20 out substantially parallel to the wall 10, but spaced therefrom an extent somewhat more than twice the thickness of the wall metal The portion 20 is then bent as illustrated 1n Fig.

'3 toward the wall so as to form a narrow neck at 21 which is of just such thickness as to make a wedging fit of the portion 13 with v the wall 9, that 1s to say, slightly less the Thus in assembling the two wall sections 9 and 10, section 10 may be set up in place together with the corresponding opposite. section, and then the back wall 9 maybe shoved into position by means of relatively soft faced hammers such as wooden structures exerting the necessary amount of force against the face 14. Before doing this, however, the sp'ace between the portion 20 and the wall 10 is filled with a suitable water proof cement or putty so that, in-dragging in the portion 13, this putty will be forced into all of the apertures through 'which leakage might occur at the joint and this provides a very efficient watertight joint.

The cement 23 may be of any suitable plastic water proofing material such for example as a waterproof cement. When the structure is completed in this fashion, it will be clear from an inspection of Fig. 2 for instance thatthe entire interior exposed surfaces of the. side and back walls need .not be subjected to any treatment that would mar them in any way during the as-' sembly, .and the water proofing material, namely the tightjoint between the member 20 and the flange 13, together with the putty at 23 are completely hidden from view making a neat and lasting interior finish. Y

In Figs. 4 and 5 I. have illustrated the application of this structure to a multiple compartment installation where the ,side walls such as 10' serve each as a side wall for two compartments. In this case the side walls 10.- are provided at their back ends with the sheet metal members 24 and 25 secured on o posite sides thereof for example by spot we ding and these members 24 and 25 extend forwardly and are bowed outwardly 'as'indicated at 26 and 27 then inwardly at 28 and 29 to form the narrow necks at 30 and 31 with the free ends 32 and '33 turned outwardly to facilitate the entry efiicient means whereby the side walls of the shower compartment may be joined without exposing any unsightly sharp edges to the interior of the compartment and with the advantage of an absolute watertight joint for the purpose of the compartment is ob tained. Also the joint is such that it permits shipping of the wall structure in knocked downgpositio n and ready assembly thereof where it is' installed without serious danger of damage to the fine finish applied thereto. It is obvious, of course, that various minor modifications may be made from the exact structure shown and described without departing from the scope ofthe invention.
