2,133,497 Patented Oct. 18, 1938> _UNITED sTATEs PATENT OFFICE 2,133,497 METALLIC SHOWER-BATH CABINET Frank T. Winston, Forest Hills, Long Island, N. Y., assignor, by mcsne assignments, to Shower Sales Corporation Application December 27, 1937, Serial No. 181,838 2 Claims. (Cl. 189-2) This invention relates to improvements in me tallic shower-bath cabinets, and comprises a con tinuation-impart of my prior patent application; Serial No. 120,643, filed January 15th, 1937. 5 One of the objects of this invention is to pro duce a portable, knock-down shower-bath cabi net which will be composed of a minimum num ber of simple parts capable of being readily, quickly and easily assembled and dis-assembled without tools by unskilled labor and also capable of being manufactured at a low cost. Another object of my invention is to provide an interlocking connection between wall members and base members which will provide an inter locking connection or joint that will be more secure and stable than interlocking connections heretofore made, and furthermore, will provide, at the bottom edge, an inwardly-extending water shedding apron which will avoid cracks Within -30 which water may penetrate to cause corrosion. With these and other objects in view, the in vention comprises the combination of members and arrangement of parts so combined as to co act and co-operate with each other in the per 5 formance of the functions and the accomplish ment of the results herein contemplated, and comprises in one of its adaptations the species or preferred form illustrated in the accompanying drawing, in which:--30 Fig. l is a view in perspective of a cabinet em bodying my invention; Fig. 2 is a horizontal view on the line 2--2 of Fig. 3, looking in the direction of the arrows; Fig. 3 is a vertical section on the line 3--3 of _, Fig. 2 partially broken away at the middle of the cabinet; Fig. 4 is a vertical section on the line 4-4 of Fig. 3 looking in the direction of the arrows, the middle part of the cabinet being broken away: Fig. 5 is an enlarged vertical section showing my interlocking connection or joint between the side walls and the bottom or base of the cabinet. Referring now to the drawing, I indicates a base member comprising a rectangular frame having at its lower end integrally-formed foot portions I’ and at its upper end vertically-extend ing ñanges la. Within the base member I is fitted and supported a pan 2, the bottom 2’ of which extends transversely and is disposed intermedi ately between the foot portion I' and the top of the flanges Ia while the side walls 2* of the pan abut the inner surface of the base member I and‘i are fastened thereto by welds 2b. . Above the weld ing portion 2b the side-walls of the pan have ver vl 5 tically-projecting flanges 2° bent inwardly to form a shoulder 2d and are spaced from the flanges Iß of the base member to provide a groove 3 therebetween. The bottom of the pan 2 is provided, at its center, with a drain-opening 2°. The -bottom of the pan 2 is also preferably sup- 5 ported intermediate its center and edges by -Z shaped reinforcing members 4 which extend com pletely around the drain opening and in parallel relationship to the 'walls of the cabinet and the base member. 10 In my cabinet, in order to reduce the number of parts and simplify the construction, I prefer ably provide opposite side-wall members 4n hav ing edges formed to provide integral door-frame stile-casings. These side-wall members will be interchangeable one with the other, thus greatly increasing the facility with which my cabinet may be erected and dismantled, and also enabling the provision, at the factory, of holes h, h' for the faucet connections in one of such side-wall mem 20 bers so that when the cabinet is erected, the in terchangeable side-walls having the faucet-holes may be disposed in the necessary position, i. e., either at the right or left-hand side of the cabi net, to enable ready connection with the faucet _ connections, it being understood that in bath cab inets, it is often necessary to position the faucet connections at the right-hand or left-hand side of the cabinet. When. erected in proper relationship to the Water supply, the stile-casing at the outer edge of each side-Wall member will provide an effec tive and efficient door-frame stile while the stile casing at the opposite rear edge, the provision of which enables the interchangeability of such side-wall members as above indicated, will also provide a more stable and firm construction which reinforces the rear-Wall. 'I'hese opposite inwardly-projecting stile members also cooper ate with the interlocking-connecting members at 40 the bottom of the cabinet so that by mere in sertion, into the cooperating grooves, of the in terlocking connections at the lower edge of the side-wall members an initial erection of both side-wall members may be effected and the rear Wall may then be readily and easily applied and fastened to produce a strong interlocked and fas tened construction. In the embodiment illustrated, each of the stile-casings 5 of the side-wall members is com 50 posed of an intermediate rectangularly-bent face-portion 5', an inwardly-turned intermediate rectangularly-bent edge-plate 5“, another inter mediate rear-plate 5b parallel with the face-plate 5' and a terminal flange 5° extending parallel 55 2 - 2,133,497 to the edge-plate- 5* so as to form a box-shaped stile-casing of rugged and strong construction for the provision, as aforesaid, ef a doorway on which a door may be hung, if desired, without difllculty. ` In accordance with my present invention, the bottom portion of each of my side-wallmembers 4, of the typev speciiied, is provided, as more par ticularly shown in Fig. 5, with an outside groove 10 making strip 5d having an outside attaching strip 5e connected to the outer surface of the walls by welds 6d, an outwardly-extending intermediate shoulder portion 5d’ and a downwardly-project ing flange 5f spaced from the outside surface of the bottom part 6b of the wall 6 to provide a groove 5l into> which is inserted the flange 2c of the pan while the said outside flange'it is in serted within the groove 3 and the bottom part 6b of said Wall 6 terminates in abutment at 6¢ 20 with the bottom of the pan 2. A double inter locking connection is thus formed in which the flange 5f interlocks with the spaced flanges of the base member and pan and the flange 2° of the panis interlocked between the flange 5f and the outerA surface of the wall 6. By the pro vision of ¿the strip 5d and flange 5f on the out side of the bottom of the wall, the inner sur face of thewall is free of projections and sheds water fromI the internal surface of the walls and l30 permits extension of said bottom part of the wall down to the bottom of the pan. Thus', when the parts are so constructed, a water-shedding and non-leaking construction is formed which will deflect Water to the center of the pan and not permit water to contact with the inter 35 will locking connections so as to produce corrosion. Furthermore, the flange on the outside surface of the bottom of my side-wall member not only produces a strong reinforcement for the bot tom edges of the wall members and enables an eilicient frictional interlock to be produced at the connection between the said wall members and the base, but prevents any possible leakage of water to the outside of the cabinet. The rear wall member 6 simply comprises a fiat panel having similar bottom interlocking con nections and adapted to flt between rear stile casings and is preferably provided along its side edges with .bent-up stile-casings 6' adapted to fit over and conform to the edge sections of the stile casings of the side-wall members so as to close such edges of the construction against the ad mission of water and the like. ` The top edges of the side-wall members are each provided with horizontal reinforcing flanges 4b produced by bending an intermediate portion inwardly and folding the marginal edge on said bent portion, and the rear-wall member is pro vided with similar horizontal reinforcing flanges 6‘. To complete the construction, a sill member 1 having an interlocking connection comprising a double flange 1’ and an inturned water shedding flange 1* in all respects similar to those herein above described, is positioned over and inter locked with the flanges of the p'an and base member to provide a brace therefore as well as completely closing the groove 3, and a top rail member 8 of angle-bar formation is seated on the opposite stile-casings with its depending ñange 8’ abutting the outer face-plates thereof 10 and, as shown, is lfastened to the top flanges by plates S. ' Having described my invention, I claim: 1. A metallic bath cabinet embodying, in combi nation, base and pan members fastened together 15 and provided with interlocking elements compris ing vertically-extending flanges spaced to form inner and outer walls of an upwardly-opening groove extending around said base and pan mem bers, and vertical wall members each having 20 interlocking elements engageable with the inter locking elements of said base and pan members and comprising an outside welded strip having a downwardly-extending interlocking flange spaced from the outer surface of the wall and in 25 interlocking position engaging within said up wardly-opening groove in the base and pan mem bers, said wall having an uninterrupted surface extending on the inside of the cabinet below said interlocking members into contact with the bot 30 tom of the pan to shed water from the upper surface of said wall members to the pan and to prevent leakage of water sprayed within the cabinet to the outside thereof. 2. A metallic bath cabinet embodying, in combi nation, base and pan members fastened together 35 and provided with interlocking elements com prising vertically-extending flanges spaced to form inner and outer walls of an upwardly-opening groove extending around said base and pan mem 40 bers, and vertical wall members each having interlocking elements engageable with the inter locking elements of said base and pan members and comprising an outside welded strip having a downwardly-extending interlocking flange spaced from the outer surface of the wall and in inter locking position engaging within said upwardly opening groove in the base and pan members, said _Wall having an uninterrupted surface extending on the inside of the cabinet below said interlock ing members into contact with the bottom of the pan to shed water from the upper surface of said wall members to the pan and to prevent leakage of water sprayed within the cabinet to the out side thereof, said wall members having integral 55 stile-casings and said interlocking connections ex tending on the outside surfaces of said stlles to enable initial erection of said side-walls on the said base and pan members.
