RECEPTOR FOB SHOWER-BATES.

Specification of Letters Patent. Applicatidn filed May 11, 1907. Serial No. 373,188.

Be it known that .I, LEO I-I. PLEINS, a.

f citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use-; ful Improvements in Receptors for Shower-z Baths, of which the following is a spec1fication. Q

The object of the presentinvention is to provide a device for use as a substltute for the floor-slabs heretofore used in the conproved receptor.

struction of shower-bath stalls, with a'view to avoiding many of the objections to which former constructions are open, and to this end the invention consists in the features of novelty that are hereinafter described.

In the accompanying drawing whic is made a part of this specification; Figure 1 is a perspective view of the lower portion of a shower-bath stall having a receptor embodying the invention, the upper portions of the walls of the stall being broken away. Figs. 2 and 3 are, respectively, a transverse and a longitudinal section thereof in vertical planes passing centrally through the drain opening. Fig. 4 is a plan view of the im- The improved receptor comprises a footslab, A, and a part, B, hereinafter called a wall-base, by which the foot-slab is bounded. The foot-slab is imperforated, saye for a drain opening, a, formed through it and preferably located near the back thereof, and its top side slopes from the four sides, respectively, toward said opening. The wall-base extends above the margins of the foot-slab and has in its top side a groove, 6, resulting in parallel flanges, b, which extend above the foot-slab and are ada ted to receive between them the lower e ges of the slabs, G, which form the walls of the stall. The groove or space between the flanges, is slightly greater in width than the thickness of the slabs, C, so 'as to leave a space which is filled with a suitable cement made, 'say, of litharge and glycerin,

- also extends below the margins of the inwardly 'sloplng foot-slab and the top and,

bottom sides of the foot-slab are preferably parallel, resulting in a dead-air space D. In order to support and strengthen the foot-slab it is provided on its under side with ribs, a, the bottoms of which lie in the u plane of the bottom of the wall-base and divide the dead-air space into a number of separate cells. v

The entire receptor is water tight, save for the drain opening, and is preferably made in a single, integral piece of porcelain glazed on its exposed surfaces, so that every integrant part of the integral structure braces and strengthens every other part and absolutely prevents their relative move,-

' ment or displacement.

The improved receptor affords means for making an absolutely water tight stall which may set directly on top of the floor as shown in Fig. 1, or completely below the floor as shown in Fig. 2, or partly in the floor as Patented Feb. 13, 1912.

shown in Fig. 3. One of its chief advantages over a floor-slab as heretofore used lies in the fact that being water tight enables it to be used in any of the wa s above described and on any floor of. a uildihg without danger of wetting the floor with consequent injury thereto and to the ceiling below.

It has been attempted to preventthe leakage which has inevitably taken place between the floor-slab and Walls of the stall, as heretofore arranged, by using a sheet of lead extending beneath the entire floor-slab and having its edges bent upward at the edges of the floor-slab, but this has been 'found in practice to be inadequate because,

in time, the floor-slab inevitably ruptures the sheet lead and permits the water to escape. It has been found also that more or less sweating takes place between the sheet lead and the floor upon which it rests because of the condensation of the moisture carried by the air in the space between the sheet lead-and the floor, this space, al.-

'though slight, being open to atmosphere.

The space referred to is due to the inevitable irregularities in the surface of the sheet lead and in the surface upon which it rests,

it being impossible to make their extensive surfaces absolutely flat. This objection is obviated by the improved receptor because of the limited area of the surfaces of contact between the wall-base of the receptor and the floor, With such limited surfaces of contact a more perfect seating of the re- .ce tor is possible than where the surfaces of contact are co'-extensive with the fioorslab. Furthermore, dead-air being a poor conductor of caloric the changes in tem erature to which the foot-slab is subjecte are not so freely transmitted to the floor as they would be if the slab contacted with it throughout its entire extent, and therefore expansion' and contraction of the floor is materially lessened. But one of the most important advantages which the improved receptor has over a floor slab as heretofore used, is the absolute rigidity, relative immovability and wa er tight union of the time.

several integrant parts, there being no joints between them that can open and cause leakage, wh1ch is bound to occur in course of What I cla1m as new and desire to secure Q by Letters Patent is,-

As a new article of manufacture, a receptor for shower baths having an-imperforated foot-slab rovided with a drain 0 ening, and a wali base bounding the foot-s ab and extending both above the u per and below the lower surfaces of the slah, the wall-base being provided in its top side with a groove resulting in parallel flanges extendin above the upper surface of the foot-slab an adapted to receive between them and confine the lower edges of wall slabs, the foot-slab being LEO H.
