Application‘ August 27, 1936, Serial No. 98,241 12 Claims. (Cl. 7-2-70) The present invention relatesto improvements A shower pan l5, which advantageously is of in pans adapted to be embedded in the masonry sheet copper, is of any desired shape to conform ?oor of shower baths to provide a waterproof to the shape of the stall and is providedwith-up _c0urse therefor; and the invention aims general standing side ?anges l6 and end ?anges, Ilia. 5' ly to improve the construction of such‘ pans as The pan is laid over the course of blocks H and 5 well as the construction of the shower bath ?oor. isrembedded in a layer ofv mortar l1 above and Heretofore in the construction’ of a masonry below the pan. The upstanding ?anges l6 and ?oor for a shower bath stall, it has been custom‘ Mia of the pan extend. upwardly. between the‘ _ ary to lay a sheet of lead on the masonry ?oor walls l2 and Wainscot 13 sothat there will be no 10 to prevent the seepage of water therethrough. chance. of leakage at theedges of the pan, and. 10 It is very di?icult to lay' such a lead sheet free these ?anges ‘l6 may belbonded to the walls by- a. from depressions or pockets which collect water layer of mortar.

Theusual tile; or . seeping through the ?oor, to the end that the other suitable ?nish l8‘ maybe provided. for the _ lead sheet soon disintegrates from a chemical upper surface of mortar layer, or the upper sur15 action between the lead and the concrete ma face of the mortarlayer' I1 may be trowelled l5 sonry.‘ Furthermore, the lead sheet is so soft and smooth as desired. . pliable that it must be laid carefully and. then The pan I5. is advantageously formed with a protected against deformation during the laying plurality of stiffening, ribs IS in» its surface to ‘re ofthe-masonry ?oor, and great dif?culty has been 20‘ :experienced due to workmen walking on the sheet before the masonry- ?oor is laid. Furthermore the mortar of the masonry ?oor does not in any way‘ adhere to- lead sheet and‘ when it expands and contracts due to sudden changes from hot ‘'1 to cold water, cracking‘ and loosening of the-?oor often results. 7 My invention aimsto overcome the above and other disadvantages by providing a pan fabri cated from a metal, such as copper, which will not 30.: rust or corrode, which will be mechanically keyed to‘ the mansonry floor and provide an impervious Waterproof course for draining any seepage to the ?oor drain. . ‘My invention will be better understood by ref 3s'z‘erence to the accompanying drawing illustra tive of one preferred construction embodying the invention and in which Fig. 1 is a central sectional view of a ?oor of a shower bath stall with my improved shower 40' pan installed therein; ~ "Fig. 2 is a fragmental perspective view of my improved shower pan; and‘ Fig. 3 is an enlarged detail sectional view through the pan on the line 3‘—3 inFig; 2. 45 In the illustrated embodiment of the invention, inforce and stiifen the body of'the paniand pref erably the sides of these ribsare inclinedor un dercut as at 20 so as to securely bondwith- the mortar l1. As herein illustrated the ribs 19 are. shown asv dovetail ribs extending transversely of the pan body, but it is to be understood thatthey may be of other cross-section and may be other- 25 wise arranged in the body of the pan. The bodyof the pan l5 between the ribs l9 con stitutes water drainage grooves or'channels 2| and preferably these channelsextend from the marginal side ?anges l6 inwardly toward the. cen ter of the panv l5 so as to drain any water that may seep through the course. I‘! centrally of the pan and towardv the drain. M. In the embodi ment of the invention illustrated wherein the ribs l9 are disposed transversely of the pan‘ I5, the said ribsv may be ?attened centrally of the pan to provide a relatively widedrainagechan nel 22 communicating with all of the grooves 21. When installing the pan, the workman has merely-‘to cut an opening. as-at 23» in they body of 40 of building blocks H, as for exampleterra cotta the pan to receive the drain l4 and to secure the pan around. said opening tightly to the drain M as. by clamping. A thin layer of mortar hav— ing previously been. spread over the: course‘ ll of blocks, the pan is ready to. be pressed into, place. When so pressed into place, the lower layer of mortar I1 fills the grooves formed. on the under side of the ribs l9 and whenthe mor blocks, commonly used by the building trades; tar hardens the pan is securely bonded to. the, the shower bath may be constructed upon a masonryfoundation l0, over which is laid a course 50;’The size-of the’ stall may be de?ned by‘ vertical walls l2, inside of which is the usual Wainscot l3, whichmay beof marble, glass, the or other suit able'material- A ?oor drain It may be embed‘ Av layer of mortar I1 is then spread over the. body of the pan and then/?lls the spaces 21' of‘ dad.‘ in, the block course H at any convenient‘ 55*? place. 1 When this'layer ofmortar' hardens,1the pan is adequately secured to‘the foundation as a whole course of blocks. . i th‘e‘pan and completely embeds the body 45.

As is well known, all masonry construction is porous to some extent and permits the seepage of water therethrough, and in the case of ma sonry employing the usual building mortar, the are adequately protected against seepage through grooves to be drained to the ?oor drain. 5. A shower pan adapted to be embedded in a cementitious ?oor of a shower bath stall hav ing a ?oor drain comprising an impervious sheet the room below by reason of the impervious non- . metal body conforming to the shape of the stall corrodible pan which collects all ‘seepage water and ?tting the floor drain, the body of said pan being formed with a series of alternate trans verse ribs and grooves adapted to be embedded in the mortar, said ribs being ?attened along at least one section of the pan to provide a 15 seepage is relatively rapid. Shower bath stalls constructed in accordance with my invention and drains it to the drain l4 through small holes in the sides of said drain. Furthermore the con struction of the pan which provides alternate 15 ribs or grooves, produces considerable ?exibility between the sides of the ribs so as to accommo date expansion and contraction of the masonry covering mechanically bonded to the pan, due to sudden changes from hot to cold water, without liability of cracking or loosening of the masonry covering. It is advantageous that the upstanding ?anges l6 and Ilia of the pan be ribbed so that they may be mechanically bonded to the walls l2 or 25 Wainscot l3 or both. In the illustrated form of the invention, wherein the ribs l9 extend trans versely of the body of the pan, the side ?anges it may be integral with the body of the pan, but the end ?anges advantageously are formed of 30 separate ribbed sheets secured to the end edges of the pan bottom and side ?anges I6, as by soldering. Advantageously, the ribs adjacent the lower edges of the end flanges “3a are ?at tened as at 24 so that they may be soldered to a 35 plain edge portion 25 of the pan bottom. Pref erably the ends of the end ?anges Ilia extend around the corner adjacent the ends of the side flanges and are secured thereto, so as to rein force and strengthen the corners of the pan. It will be apparent to those skilled in the art that the invention is not restricted to the par ticular shape or arrangement of the ribs or other 45 drainage valley communicating with all of said grooves whereby water of in?ltration collected in said grooves may be drained to the ?oor drain. 6. A shower pan adapted to be embedded in a. cementitious ?oor of a shower bath stall which 20 is provided with a ?oor drain, comprising a sheet metal pan conforming in shape to the stall and formed with peripheral upstanding ?anges, the body of said sheet being formed with trans versely arranged alternate dovetail ribs and 25 grooves adapted to be bonded to said cementi tious floor, and means establishing drainage communication from all of said grooves to the ?oor drain.
