(Cl. 4—173) 'I’hi's‘invention relates to an improved bathtub. 2 and 3 are enlarged detail sectional views After extended use of‘the customary built-in vthereof, taken respectively on lines 2—-2 and 3-3 bathtub, it frequently occurs that the top edge of Fig. 1. of the tub separates from the wall structure caus ing a leak between the top- edge and the wall, enabling water to ‘seep into the wall and produce damagefthereto; , ’ , , _ ' bers .of the wall. .1 Fig. 5 is a partial sectional View, similar to that . It has been proposed to use attachingbrack'ets and attachments for" connecting ‘the top edge of 10 the tub and the wall,v to avoid such separation andleakage;.but these are objectionable, since they cause addedexpense in the manufacture and extra work and trouble in the installation, and do not fully solve the dif?culty. 15 Fig. 4 is a partial sectionalview of the tub in- , stalled and secured to the vertical frame mem?

I10 In the drawing my improved bathtub is illus trated in its preferred form of construction, com prising the customary main portion or body ill from the upper edge of which extend the ledges or shelf portions substantially horizontally out wards, including the front and rear side ledges 15 II and I2, and the two end ledges l3 and I3’. From the front ledge ll depends the front wall or apron l4, integral therewith and depending constantly secure and positively leak-proof con down therefrom to the ?oor. ‘ The rear ledge I2, and also one or both of the 20 and the wall, and thus obviate the necessity of end ledges I3 and I3’, according to whether one or both of the ends are built into the wall struc 20 nection between the upper part of the bathtub using any separate and additional attaching members. . ' I Another object of this invention is to provide 25 a built-in bathtub having integral ‘?ange means at its upper end which is arranged and equipped for conveniently and securely fastening the tub to'the wall structure to remain ?rmly in position; and is also arranged and equipped so as to pro 30 vide a positively leak-proof bonding connection between the upper part of the tub and’the wall. - A further object is to provide such a bathtub with an integral mounting ?ange which is pro vided with openings therein for substantially the 35 entire length of the ?ange, so that fastening ele ments may be conveniently placed therethru into the upright frame members of the wall, no mat ter where these members may be located along the ?ange, and these openings will also serve as 40 anchorage spaces for the ?nishing material of the wall. ’ _ ‘ These and various other objects and advantages are attained with this invention, as will become apparent from the following description, taken 45 in connection with the accompanying drawing in which this invention is illustrated in its pre ferred form of construction; it being understood that various other arrangements and forms of 50 construction may be resorted to for carrying out the objects and purposes of this invention. In the drawing: Fig. 1 is a perspective view of a bathtub em bodying this invention in its preferred form of 55 construction. ture, are provided with upwardly extending ?anges I6, and l‘! and I1’, respectively. These upstanding ?anges are integral with their respec 25 tive horizontal ledges l2, and I3 and I3’. Slots ‘l8, and I 9 and I9’, are provided respectively in said ?anges l6, and I‘! and I1’, and extend hori zontally lengthwise thereof. Solidportions or vertical ribs 20 are retained at the corner parts 30 of these ?anges, and similar solid portions or ribs 20' are left unslotted between the slots in said ?anges, apertures 2| being provided in said solid portion or ribs, as best shown in Fig. 1. The slots l8, l9 and I9’, provide openings along 35 substantially the entire length of the ?anges l6, l1 and I1’, and more fully so when the apertures 2| are considered in conjunction therewith, wherethru securing elements 22 can be conven iently entered at any desired position along the 40 ?anges, so that such securing elements can be readily fastened into the studdings or vertical frame members 23 of the wall structure, as such members are usually spaced from 16 inches to 24 inches apart, and these elements can be conven 45 iently driven into said members no matter where they may be located along the ?anges. The se curing elements used in the slots are preferably in the form of screws having laterally extending heads 22’, as indicated in Fig. 4, so that the heads 50 may be turned horizontally and passed thru the slots if desired. Screws may likewise be extended ' ' thru apertures 2!, as indicated by the screw 24 in Fig. 5. I It is preferred to provide grooves 25 additional 65 2,128,424 2,. 1y on the lower part of each ?ange, on the tub side away from the frame member, and prefer ably also to provide serrations 26 along said tub side of each ?ange, as best shown in Fig. 3. The slots extending longitudinally and substantially thruout the length thereof and having solid por tions therebetween provided with apertures, said slots and apertures providing openings for receiv ing securing elements to secure the tub to up right wall members that may be located any~ where along the length of the ?ange means, said ?ange means also having groove means provided therein, which with the slots and apertures are adapted to receive the ?nishing material of the 10 wall to bond the top of the tub securely and leak proof to the wall.
