ATTRNEY Patented May 4, 1937 l l :UNITED STATES PATENT OFFICE DRAIN? David S. Williams, Portland, Oreg. Application March 2s, 1936, serial No. 70,369

v 14 claims. (C1. 13s-32) This invention relates to improvements in drain fixtures for roofs and the like and more specifically to roof fittings of the dome type.

It is within the contemplation of my invention to utilize the gases, which are normally generated in sewers, for maintaining the drain,constructed in accordance with my invention, in working condition even in extremely cold weather. It is universally acknowledged that the waste disposals 1n in sewers generate gas;` and, inthe chemical reaction which takes place, suiiicient heat is given off. Some of this heated gas finds its way into the drain pipes and other outlets. By constructe ing my invention in the manner hereinafter to l5 be more particularly illustrated, these warm gases passing through the drain pipe to which the drain is connected are directed or shunted in such manner as to adequately warm the drain fixture and thereby maintain it in operating condition regardless of any severe weather.

The present types of roof drains do not provide against the possibility of excessive snow or frost completely rendering the roof xture inoperative. One of the principal objects of my invention is Q5 to provde a frost drain whichV will at all times be maintained in operative condition regardless of the weather.

Another important object of the invention is to provide a multi-slotted member and a cap therefor as a part of the drain fixture which provide against the contingency of the drain being rendered inoperative by dbris or other foreign substances.

Another equally important object of the invention is to provide a member possessing ample slots to afford sufficient waterways or drainage area for normal storm conditions and additional slots on the roof or dome of the member which accepts any overflow resulting from severe storm conditions, thereby assuring against flooded roofs caused either by excessive rains or as a result of the lower slots being clogged by dbris.

A further object of the invention is 'to provide means whereby parts of the drain xture are accessible for replacement or may be readily serviced or the flashing renewed.

Another object of the invention is to provide means within the drain ixture which prevents the forming of undesirable pools or water pockets in the base of the drain fixture or adjacent the meeting edges of the flashing and the drain fixture.

A salient object of the invention is to provide dome-shaped slotted means for protecting the drain fixture against being completely clogged by dbris or being frozen over.

. `A further object of the invention is to provide means for directing the gases .emanating Vfrom the drain pipe.

Not all of the objects, advantages and characteristic features have been stated. Many more 5 will become apparent from the following description and accompanying drawing which illustrates. by way of example, the application of the invention, vin which:

Figure 1 is a vertical section of a drain fixture lo embodying the principlesiof my invention shown as applied to a roof.

Figure 2 is a plan View of the device illustrated in Figure 1 with the cap member partially broken away to reveal the relative position of the drainl. age slots in the drainage member.

Figure 3 is a fragmentary, sectional view, parytially broken away, of a portion of the device shown in Figures 1 and 2, taken on line 3-3 of FigureZ, looking in the direction indicated, the 20 same being proportionately magnied to more graphically showthe details of construction and the openings toj carry o the water.

Figure`4 is a side view of the lower body portionof the drain fixture with a portion broken 25 away to show the position of the bolts within'the lower body portion.

The drain fitting embodying my invention consists of a support body generally designated by reference character A which possesses certain 30 structural characteristics now to be described. Internally threaded bore l is a part of the support body. 'A drain pipe (not shown) is threadably connected to the bore, but any water tight co-nnection between the bore and the drain pipe may 35 be used instead of a threaded connection. An inverted frusto-conical annular portion 2 integrally extends from bore l. Integral with portion 2 is a vertically extending annular portion 3. Formed as an extension of portions 3 is a later- 40 ally extending annular shoulder 4, and an inverted frusto-conical tapered annular flange t extends from shoulder fl.

A number of bolt anchoring and retaining recesses 6 are formed within portion 3 and pass 45 through a portion of shoulder 4. Lugs 'l are formed on the outside 'surface ofportion 3 in order to provide sufcient area for recesses 6 and to provide means for iXedly anchoring the whole 50 of the support body securely to the supporting surface, such as a roof. Threaded bolts 8 are removably disposed in recesses 6 so that the heads 9 of the bolts fit substantially snugly within the wide portions l0 of the recesses 6 and the 55 stems II of the bolts fit into the narrow portions I2 of the recesses and protrude substantially beyond the recesses.

An annular retaining and anchoring plate I3 is adapted for seating upon shoulder 4. It is, however, positioned so that its inner margin or periphery I4 avoids covering the narrow portions I2 of recesses 6 Which pass through shoulder 4. It is to be noted that there are no openings for bolts or other fastening means, thus eliminating the possibility of damaging the flashing without sacrificing a water tight connection.

The drain fixture embodying my invention also embodies a drain member designated generally by reference character B. This member is formed with a cylindrical wall I5 possessing therein a number of radially and vertically disposed elongated slots I6. The cylindrical Wall I5 extends upwardly and converges at apex l1 of dome portion I8. The dome portion I8 is itself4 provided with radially disposed slots I9. Slots I6 and I9 are separated from each other by annular portion which has an additional function hereinafter to be more specifically referred to. A laterally extending annular nange 2I is formed around the outer surface of wall I5 in coinciding relationship to the bases of slots I6. Holes 22 are provided within flange 2| so that they register with recesses 6 in order to permit the stems II of bolts 8 to pass therethrough. Flange ZI is not only seated on annular retaining plate I3 and functions not only to secure the drain member B againstsupport body A, but also to securely anchor the retaining plate I3 against the roof covering toprovide a water tight connection therewith. This is accomplished by threading tightly nuts 8A about stem II. An annular rim 23 extends below ange 2| and is a prolongation of wall I5 so that its periphery 24 is ibelow and in spaced relationship with shoulder 4. By this construction, provision is made for an annular passage 25 into which a number .of ports 26, formed within the under side of flange 2|, open, These ports not only act as drain openi ings toallow water to enter into the drain pipes, but also allow some ofthe gases generated in the sewer lines and emanating from the drain pipe to `escape therethrough and thereby raise the temperature around the area immediately adjacent to these ports.

`An inverted frusto-conical annular member, generally designated by reference character C, is positioned within support body A in spaced relationship to annular portion 3. This is accomplished by providing a number of legs 21 which extend from member C and which have their bases 28 beveled to coincide with the inclined surface 29 of annular portion 3. The outer peripheral edge 39 of member C is spaced from rim 23 and lies slightly below slots IB. The circumference of the inner peripheral edge 3| is slightly less than the circumference of the drain pipe (not shown). Member "C functions to direct the gases toward the annular passage 25 and ports 26 as well as toward'the inner surface of Wall I5.

Another important unit of the drain fitting embodying my invention is a dome-shaped cap designated generally by reference character D.

This cap is adapted to be seated upon and in spaced relation to the dome portion I8 and is removably secured to apex I1. To accomplish the above objects, a hub 32 is provided which extends downwardly from the center of the cap.

.A smaller hub 33 extends from hub 32. Hub 33 ts snugly within an opening 34 formed in apex I1. Another opening 35 passes through hubs 32 and 33 to accommodate pin 36. A wa'sher 31 is positioned around pin 36 and is held against the inner surface of the apex I'l in any desirable manner, as by cotter key 38. To give additional support to cap "D and to provide against its movement relative to the drain member B, a number of feet 39 are provided. These feet extend inwardly from the cap so that their beveled bases 4U rest upon annular portion 20. Adjacent the periphery of the cap are formed a number of radially disposed slots 4I which receive ilood waters in the event the slots I 6 are clogged by debris.

My invention-may be used on any type of roof whether of wood, metal or composition; and it may also be used for floor drains where considerable refuse is created, such as meat packing establishments and factories. In use, the body .A" is placed so .that the periphery of the tapered annular flange 5 is flush with the roof surface, as illustrated in cross-section in Figure 1. The flashing material of whatever composition is then placed overthe upper surface of the flange 5 and shoulder 4 of bodyfA, see Figures l and 3. The annular plate I3 is thenplaced over the flashing material which rests on shoulder 4. The water tight connection vbetween the body A, the hashing material and the plate I3 is produced by placing the ilange 2l over a portion of plate I3 with the bolts 8 passing through the openings in the flange 2l. When the nuts 8A are securely threaded about the stems of bolts 8, not only is pressure applied upon plate I3 and in turn upon the flashing material, but the drain body B is securely held against support body A. It is understood, of course, that member C is placed into position before drain body B is secured as stated above.

The dome-shaped cup D not only guards the dome portion I8 of drain body B and prevents the clogging of slots I9, but also accumulates the Warm gases and keeps the slots from becoming closed by frost. The cap D also provides additional drainage area by the slots 4I.

The foregoing describes the form embodying my invention, as exempliiied in the drawing, but I claim all such modifications of the form illustrated as fairly fall within the scope of the lnvention dened in the appended claims.
