PATENT oer 1' JOSEPH HIRSHSTEIN, or" CLEVELAND, oH-Idi oIiAMPINe MEANS;

Application fiiedrebruar 15; 1923. Serial-No. eiaiei.

My invention pertains'to drains fonroofs orfloors' and relates to means for holding a flashing or the surface sheet of water'- proof material in engagement with the drain.- The object of the invention is to provide a means for the purpose mentioned which willnotrequire perforation of the waterproof material orthe provision of co operating' boltor screw openings in" the clamping ring or'drain. The invention" is particularly applicable to and advantageous in connect-ion with drains which-have a recessed portion positioned below the surface to be drained and in which is seated a re movable strainen In the accompanyingdrawings, Figl is a cross" sectional View illustrating an' embodiment of myinVention'; Figs. 2 and? are side and rear ,elevational views respectively of the clamp holding member and associated"partsfFig, l is a crossjsection on the line t-lbfltig. 3 and Figs. 5 and 6 illustr'ate a modified form of clamp h ol din Tmeans'. V

l represents-a d rain'bo'dy adapted to be positioned in a} floor] or roof v and" provided with a recessec'l portionin which is seated a removable strainer 2 provided with a circumferential flange 3 forming" a sediment receiving cup and -means for withdrawing from the drain sediment which collects in and above said cup and around the strainer. A sheet of waterproof material 4 which forms the top surface of the floor or roof extends over the perimeter of the drain body as shown and is held in clamped relation therewith by means of the annular clamping ring 5.

It has heretofore been the practice to hold the clamping ring in position by means of bolts or screws passing through it and through the waterproof material and into or through the drain flange. This construction has the disadvantages ofrequiring the making of holes through the waterproof material, of the locating of the openings in he clamping ring, waterproof material and drain, in alignment for insertion of the clamping bolts and of difficulties in proportioning the length of bolts and extent of openings in the drain body to accommodate sheets of waterproof material of various thicknesses. To avoid the difiiculties mentioned in the prior structure, I provide the drain body with integral spaced lugs 6 having ahorizonta'lly extending por tion, through which a vertical openingis made; and, on the wall" of the" drain body and in alignment with these openings, .I provided locking teeth 7. The clamp holding' member 8 has a vertical leg passing through the opening through'thelugb and a]. horizontal leg-extending over the clamping ring 5, the horizontal ,leg'ibeingfprovided Wit-h a set crew-'9 in threaded en'- gagementftherewith and adapted to bearupon the clamping ring. I prefer to" use either three or four clamp holding members suitably spaced apart. 1 I

j The vertical QpeiiiIigsin" the h1g6 are slightly over sizeti ith respect tothefver tic'al leg of the clain 'iholdingmember 8 and? the lon' 'er" ends" of" these" legs are pro} vided with spacedmotcihes fbr engagement withthe teeth i', whereby thec'lamp hold.- ing niemberfcan be" adjusted vertically to ac onimo date for varying-thicknesses of the waterproof material 4.

7 Pressure between the screw 9 and, the cla m ngring 5fcauses the walls ofithe openings in the lugs 6']to' aot as'fulcrums, whereby pressureis applied tohold the" coo perating teeth and 7 selected notches en gagenient, and thtisfa sec rel'aijid satisfactory clamping" of the waterproof material between the periphery of the diam aiid the clampingring is obtained. The play between the vertical leg of the clamp holding member and the opening through which it passes is suflic-ient to permit disengagement of the teeth and notches and the adjustment or removal of the clamp holding member from the lugs 6 when desired.

In the modification shown in Figs. 5 and 6 wedging clamp 10 eccentrically mounted on the horizontal leg of the clamp holding member 8 is substituted for the set screw shown in the other figures. Y

I claim: I

1. In a device of the class described, the combination of a drain body having a recessed portion provided with a water outlet, a sheet of Water-proof material, an annular clamping member for holding said material in engagement with the drain body above the recessed portion and means extending into the recessed portion and engaging with the clamping member and the drain to hold said member in clamping position, said means being located out of the surface of the drain a ainst which material is clamped.

2. In a device of the class described, the combination of a drain, a sheet of waterproof material, a clamping member for holding said material in engagement with the drain, a clamp holding member, means on the drain body forming a vertical opening for the passage of the clamp holding member and inter-engaging locking means on said member and the inner lateral wall of said drain body.

3. In a device of the class described, the combination of a drain, a sheet of waterproof material, a clamping member for holding said material in engagement with the drain, means on the drain body located out of the surface of the drain against which the waterproof material is clamped and forming a vertical opening, an adjustable clamp holding member passing therethrough, and means for holding the clamping memberin adjusted position.

l. In a device of the class described, the combination of a drain, a sheet of waterproof material, a clamping member for holding said material in engagement with the drain, means on the drain body forming a vertical opening, an L-shaped clamp holding member having one leg extending over the clamping member and the other passing through said vertical opening and engaging the drain body and means carried by the first mentioned leg of the clamp holding member to apply pressure to the clamping member, the opening through which the clamp holder passes being so positioned that its walls serve as a fulcrum whereby application of pressure between the clamping member and holder increases the engagthe water-proof ing pressure between the vertical leg of the holder and the drain.

5. In a device of the class described the combination of a drain body provided with a recessed portion, a sheet of waterproof material, a clamp member for holding said material in engagement with the drain, an L-shaped clamp holder having its horizontal leg extending over the clamping member and its vertical leg extending into the recessed portion, means on the wall of the recessed portion forming a slightly oversized opening for the passage of said vertical leg, said vertical leg and the wall of the recessed portion being provided with inter-engaging teeth, a clamping screw in threaded engagement with the horizontal leg of the clamp holder and bearing upon the clamping member, the vertical planes of the passage-way, teeth, and clamping screw being in such relation that pressure between the clamping screw and the clamping member causes said teeth to be held in engage ment. 7

6. In a device of the class described, the

combination of a drain body, a sheet of waterproof material, an annular clamping member for holding said material in engagement with the surface of the drain body, and a clamp holding member having a vertical leg passing from a point below to a point above the clamping member and located within the inner edge of said member, said holding member being provided with a lateral extension projecting over the upper surface of the clamping member.

In testimony whereof, I have hereunto set my hand and afiXed my seal.
