A Conroe-Arion or .DELAWARE DRAIN' Application filed.l October 20, 1926.

This invention pertains to drains for roofs or ioors and more :particularly to. the prol vision of means for effecting a water tight 5.0 and the floor material.

connection between the side of the drain and The usual practice for maintaining a water tight connection be tween the drain body and the floor or roof,

is to employ a sheet of waterprooling material which is placed beneath the floor, and is shaped to surround the drain body. form of means for securing the flashing has necessitated the drilling and tapping of the drain body at spaced points. This cannot be done in a satisfactory manner, except at the f manufacturing plant, and consequently con siderable caution must be exercised 1n preparing the proper drain for each order, since some drains do not require the clamping apparatus. l

An object of the present invention is to provide means for holding the flashing in place against the drain body, without neces sitating the use of a tapped opening in the body, and without requiring cementing material, or the making of any holes through the flashing. Thus l provide fastening means which may be readily installed on the job in an expeditious manner.

T he preferred means for carrying out my invention is shown in the drawings, wherein Fig. 1 is a plan view of a drain having my invention embodied therein; Fig. 2 is a vertical section talren through the drainon a plane indicated by the line 2--2 in Fig. l; Fig. 3 is a similar section showing one of the clamping members in position for removal; Fig. 4t is a perspective view of one of the fasteningmembers; and Fig. 5 is a perspective view of part of the drain body.

The drain illustrated is one wherein the body 1() is provided with an adjustable head 11, which is adapted to be positioned flush with the floor or roof level, and is also provided with a seepage collecting panV or receptacle 12. The pan surrounds the drain body and is adapted to discharge into the drain through openings 13, any liquid which may be collected by the pan. This pan collects liquid which may leak between the drain Consequently, in

whichterminates in a1 horizontally disposed pad '21. "A lug 22 eX tends laterally from each side of the arm 20 and adjacent the shoulder 23 is formed in the armabove the top surface of the lugs. Moreover, the pad bottom thereof, while a' has a threaded opening 24, through which a.

set screw 25 may extend.

To hold each clamping member in position, the drain ybody has spaced groups of lugs, there being one group member.

Moreover, the lug at a suiiicient height above the horizontal. seat 12 to permit engagement with the shoulto each clamping 5 shows one of such'groups,y a lug 30 which extends later- -V 30 is positioned Y lugs lwhich are f spaced from the wall of the body a distance,

Each clamping member has bottom por,-rv 20 rounded, as at 27, to permit turning of the arm with'reference tothe tion of the arm body, whereby the clamping member may be inserted into place or removed from the,

be accomplished leo drain. Such operation may by loosening the set screw, and then lowervfor clamping ing the pad 2l until the shoulder 23 clears the lug 30 as shown in Fig. 3. The clamping` member may then be lifted out of place. Conversely, the member may be inserted into position by placing the lugs 22 between the lugs 3l` and the body, and then raising the arm until the shoulder23 engages beneath the lug 30. Thereupon the set screw tightened untilV the lower end thereof engagesthe clamping ring. Thereafter, each set screw may be selectively adjusted to attain the desired clamping pressure.

A clamping device made in accordance with my invention is advantageous, in that the flashing may be satisfactorily held in position against the drain without requiring theV use of a threaded connection with the drain. bodyl Consequently, all drain bodiesmay be .made in Athe saine. wa i and: Ithen those Whichareintended'for use with waterproofV` ing. material maybe` furnished withV additional clamping. members..
