Another object of this invention is to provide a leak proof combination roof and floor drain 'characterized by versatilityof application, simplicity of construction and efiiciencyfofop'era tion.
Other objects and advantages of this invention will be readilyV ascertainedrfrom thefolloWing specification and drawing in which:
Fig. 1 is a vertical front view of the roof type drain; Y I
Fig. 2 is a top view of the roof type drain; Fig. 3 is a vertical section taken alongthe lines3-3ofFig.2; Fig. 4 is a horizontal section taken along lines II-.4ofFig.1; Y Fig. 5 is a vertical section of theflo'or type drain; and y Fig. 6 is a top view of the floor type drain. While this invention is susceptible of various modifications and alternative constructions, it is shown in the drawings and kWill hereinafter be described in preferred embodiments. It isnecesfalling within the spirit and scope ofthe inven-KV tion as defined inthe appended claims.
This application represents improvements in my roof drain described and claimed inmy Pat-` ent No. 2,284,416 of May 26, 1942.
The drain generally designated at I comprises a main body portion 2, a top portion 3 through which fluids are strained before entering the drain, agravel and trash stop 4 intermediate I the main body portion and the top portion, and
a lower portion 5 which is adapted for connecting the drain to an ordinary standard drain pipe'.
The main body portion of the drain is of cylindrical shape having its top portion formed into an outwardly extending flange 6, said flange being parallel to either the'roof or floor into which the drain is to be set. Intermediate the main body portion and the periphery of flange i5 is a rounded depression' 'I having directly below it a relatively thick portion 8 ofthe flange t. The uppermost edge ofthe flange 6 is adapted to fit flush with the top of the concrete roof or iloor.
Thejupper part Aof this drain comprises a dome like or beehive structure 9 having a plurality of apertures I0 therein for straining out foreign materials in the fluid to be drained. The lower portion of the beehive structure has an outwardly extending flange I I having a rounded depending bead I2 thereon, and .fis adapted to fit snugly against the outwardly extending flange 6 `of the main body portion. Around its periphery, the flange I I has an upraised edge I3, said edge having formed therein a plurality of notches I4 which are adapted to prevent the entry of gravel, trash and the like into the drain.
It is kan object of this invention to have a leak proof drain. To that end, there is inserted between the flange` II on the top portion and the flange 6 on the main body portion, a sealing medium I 5. Though this medium may comprise l any one of numerous materials, it is shown in the drawings and herein described as roofing paper. Y The roofing paper is first inserted over the outwardly extending ,flange 6 of the main body portion and then the entire top structure of the drain is set down upon the roofing paper in such a manner that the depending bead I2 formed on the flange Il forces the sealing medium down wardly into the depressions 'I of the flange 6 formed on thev main vbody portion of the drain. In order to cause a tig-ht sealbetween the top and main body portionsnthere are provided bolts I6 extending from thearea between the beehive and the edge I3 downwardly into the main body portion of the drain.
This drain is adapted primarily for use in concrete roofs or floors. A primary advantage of the drain is Athat it may lbe set into the concrete structure at almost any stage in the construction. It may for instance be set in place just prior to the pouring of the concrete. After the pouring of the concrete the beehive structure may then be attached.
A primary advantage of this drain is the interchangeability of the top portion thereof so that it may be attached either for use as a roof drain or a iioor drain. Heretofore, drains, including the drain shown in my Patent No. 2,284,416, were constructed in such a way that the top portion and themain bodyy portions could not be readily detached' one from the-other. It became necessary therefore, to manufacture and use completely separate drainage units for roof use and oor use. mainbody structure 2 and the lower portion 5 of the drain are constructed as a unit, butfthese` two sections are completely separate from, theV uppermost portion of the drain. For this reason, it is quite convenient to afiix a different type of top to the drain depending upon the applica tionA to, be made with the drain. For instance, if the drain is to be applied to ay roof a beehive type top, such as is shown in Figs. 1, 2, 3 and 4 maybe utilized. However, if the drain is to be used in a fioor, the same basic structure may be used except that a fiat top such as is shown in Figs. and 6 may be aixed to the main body portion in the same manner in which the beehive structure was attached as was previously described.
This drain is provided with an efficient and quick operating slip joint between the lower portion of the drain and a standard drain pipe. Tc this end, the lowermost portion 5 of the drain is larger than a standard drain pipe and provided with an outwardly extending bell il forming within the4 cylindrical lower portion of the drain an enlarged circumferential recess i8. An internal flange 29. is integral with the lower end of the portion 5 and has an internal diameter just slightly larger than the O. D. of the pipe I9. A standard drain pipe I9 is .first inserted upwardly through flange 29 into the lower portion of the drain leaving a circumferential space between the standard drain pipe and the-- drain body. Some appropriate sealing means such as oakum is compressed into the space between the standard pipe and the drain. Approximately one-half of the space is filled withoalrum. The remaining space between the drain pipe and the drain is filled with leadl which lls the enlarged recess 18 thereby fastening thejoi-nt.
One of the. principal advantages of .my-.invention is the provision of a combination floor and roof drain having improved reinforcing qualities when used in concrete. It is wellknown that when drains are installed in either concrete roofs or concrete floors the concrete immediately surrounding the drain soon begins to crumble and fall away making it possible for the drain to be moved in such amanner as to shake it loose.- In order to prevent this crumbling it became necessary to provide a reinforcing means for connecting the drain to the concrete. My pre-` vious Patent No. 2,284,416 shows a type of re-v inforcement comprising lugs attached to -the main body of the drain and having connected thereto outwardly extending reinforcing rods. The reinforcing means shown in this application are considerably improved over that shown in my previous patent. The. means comprises a circumferential perforatedv disc 2 0 ywhich is affixed to the circumference of the` cylindrical main body portion of the drain. This perforated disc 20 formed cf two halves lM and Z2,
In this applicationV theV having thereon a plurality of perforations 23 extends outwardly from the drain a sufficient distance to adequately reinforce the concrete into which the drain is set. It is shown in Figs. 1 through 4 as extending slightly beyond the outer circumference of the gravel stop 4. This perforated plate serves numerous advantages. If the concrete generally shown as 24 into which the drain is set has not been previously reinforced, the perforated" disc will supplant the! ordinary reinforcement and prevent the concrete from cracking and crumbling. If the concrete has previously been reinforced by ordinary reinforcing .means theperforated disc 20 serves an important function in that it serves as a means for connecting-thedrain proper to the reinforcing means al- Vready in theconcrete, This provides a continuous -reinforcementfor the concrete up to the drain and does.` not permit the concrete immediately surrounding the drain to be unprotected. In addition to the foregoing advantages the perforated disc also serves the functionof partially supportingthe weight` of the` concrete above it. Such support adds immeasurably to the prevention of any crumbling of concrete immediately surrounding the drain.
in. order to properly affix the two halves of the perforated plate or disc in the drain, the lower portion of the main body portion 2. of the drain is provided with av plurality of outwardly extending lugs 25 having atleast onehole such as is shown at 2t, formed therein. from top to bottom. Each half of the perforated plate is designed to rest on. portions of more` than one of the outwardly extending lugs as shown in Fig. 4. In order to prevent vertical or horizontal movement of the perforated disc, tie-wires 2l are` used, one end of each being inserted through holes in the disc downwardly through` the bore of a lug; the opposite end of the tie-wire is inserted downwardly through another hole in the disc and along the outward end of the lugs 25. The free ends of each tie-wire are. then twisted together and tightened to draw the disc 2li firmly against lugs4 25 and inwardly against the outer surface of the main body portion 2 of the drain.
The preceding description was primarily directed to Figs. 1. 2. 3 and 4 which show the drain in the embodiment used for roof installation. The same type drain |0| is shown in Figs. 5 and 6 except that the beehive. type` portion has been replaced by a flat plate |00. AThis flat plate which is bolted by means of bolts H6 tothe main body |02 of the drain has therein a plurality of longitudinally extendingr apertures ||0 cut therein. The remaining structure of the drainuis the same as that shown in Figs. 1 through 4, the drain cornprising a main body section |02 and a lower section |05 having inserted therein a standard drain pipe l |91, said pipe and lower. section of the drain being connected by a slip joint of leadv |08 and a suitable packing |05)V such as oak-um. v
The drain shown in Figs. 5 and 6 is a completely sealed drain pipe by virtue of ther sealing tar paper l5 which is inserted between the topV portion and the main body of the drain and the flat plate |00.
This drain is, alsoA providedvwith reinforcing means for the concrete. .110er |2101? Withmeans connecting the main body Qi the ,drain t9-Preve ously installed concrete reinforcements. The" means comprises a circular perforated dise 129.
just asthe disc 2li-in Egs.- l through 4.
Though the description of both ofthese drains has been given in temas of a concrete base, it is t0 be understood dat sach. a grammar be. in:
stalled in any other suitable composition such as metal tile, marble, cement, terrazzo or wood sheathing. In the event the installation is made in wood sheathing, the top portion of the drain is provided with wood screws which are used to aix the drain to a wooden structure.
