6 Claims.

This invention relates to floor drains adapted to be secured to the upper end of the conduit leading to the sewer.

Usually the conduits arepositioned in a building structure prior to the laying of the floor which is usually of concrete and are originally set with the upper end sufficiently above the base on which the floor is to be laid and the drain conduit is usually required to be out olf at the upper end or broken as by a chisel to permit the floor drain head to be positioned with the upper surface thereof at approximately the floor level. This usual procedure results in a ragged upper edge of the conduit which catches lint and other refuse discharging through the drain head.

The purpose of this invention therefore is to provide a drain head with which is associated an' internal ange angularly disposed downwardly and inwardly and of a length to overlie the upper ragged end of the conduit to which the drain head is to be attached thereby preventing clogging of the inlet end of the outlet conduit.

Several forms of drainage fittings of such structure as to secure the said features and objects of the invention are shown in the accompanying drawings in which- Fig. 1 is a vertical section through a iloor drain showing an integral internalflange overlying the inlet end of the outlet conduit.

Fig. 2 is a half section showing another form of my improved drainage fitting including a separate flange overlying the upper end of the waste conduit.

Fig. 3 is a vertical section showing an alternative form of a drainage fitting for use in conjunction with a basket having an external flang supported by the drain head. Y

Fig. 4 is a similar view showing the basket formed with an out-turned flange supported by a flange provided on the body.

Fig. 5 is a vertical section of a drainage fitting showing a basket removably supported by the iiange of the drain head and including a means permitting now of liquid into the outlet conduit when the basket becomes clogged.

Fig. Y6 is a vertical section showing another form of construction showing a drainage by-pass through the basket. 1 K I f The invention in its simplest form isshown in Fig. 1 in which the usual vertical portion of the outlet conduitis shown at I and which originally extended upwardly a distance above theupper` end indicated by the dotted lines a in Fig. 1.

Prior to the placing of the concrete and after the floor level is established, the fitting comprising the body 3 and head 1I, are placed in position in assembled relation and the concrete is then poured subsequent to securing the body 3 to the conduit as by means of the threaded bolts 5 which center the fitting on the conduit I. The space 6 is provided between the body 3 and the conduit to receive a caulking material 1 shown in Fig. 1, as is the usual practice. Caulking material is similarly used in each of the forms of the invention shown.

The body 3 is provided with a flange 8 shown at the left side of Fig. 1 which may have the upturned flange 9 or it may be made without such upturned nange as is shown at the right hand side of Iiig. 2.

The drain head II as shown in Fig. l has an integral peripheral flange I0 which is secured as by means of screws II to'the iiange 8 of the body. Between the two anges 8 and I0 is secured a flashing I2 usually provided to prevent seepage through the concrete floor. A series of apertures I3 are provided above the ange I0 as shown to permit any liquids seeping into the concrete to discharge into the fitting. However drainage may be provided in either of the forms of the invention shown as is illustrated at I 3a in Fig. 2, in which case openings I3 need not be provided.

In the form of my improved drainage fitting shown-in Fig, 2 the flange Illa is integral with the head and carries the internal flange I4a which overlies the upper end of the waste conduit `and serves the same purpose as the flange I4 of Fig. 1.

The principal feature of the invention as above described resides in the provision of a downwardly inclined flange I4 or Ila having an opening I5'in the bottom of approximately the same diameter as the internal diameter of the drainage conduit l and thus extends over the upper end of the conduit I and directs allmaterial flowing through the grating I6 or the drainage openings I3 or I3a. into the discharge conduit I. The flange prevents floating material, such as lint for instance, from accumulating on the ragged upper end of the conduit I.

The drain head 4a is similar to that shown in Fig. 1 in that it has an inturned flange or apron Ida that extends over the upper end of the drainage conduit la but is not an integral part of the head 4a. The head III-'a has drainage openings Iv3a leading to within the body of the drain head as described relative to the structure shown in Fig. l, and also has a removable grating.

In the form of the invention shown in Fig. 3 the head 4c has lugs `I1 on the upper end of which the grating rests. These lugs have a recess I8 to receive the outer edge I9 of the flange 20 of the perforate basket 2l. By removal of the grating the basket may be removed for the purpose of cleaning and to permit access to the flange llb which may be required to be cleaned and which prevents the hand of the person from coming into contact with the ragged or broken end of the conduit la.

As shown in Fig. 4 the head 4c is not provided with an internal flange but the basket 22 is provided with an inclined wall 23 supported by an internal flange 24 integral with the body and overlying the upper ragged edge of the waste conduit Ib. Upon removal of the basket and grating for the purpose of cleaning, the ilange 'Mv serves as a protection for the hand. By providing notches 25 in the inner edge of the flange 24 and apertures 28 in the inclined flange 2.3 of the basket, liquid may still pass to the outlet when the lower apertures 2l of the basket become clogged by accumulation of dirt and refuse.

In the form of the invention shown in Fig. 5, the drain head a has an inwardly and downwardly projecting flange 2|a overlying the upper end of the outlet conduit 22a. The grating member 23a, has drainage apertures 24a and centrally disposed in the grating member 23a is a vertical conduit a opening through the upper face of the grating preferably at its center and extending through an aperture provided therefor in the bottom of the basket.

The perforate basket 26a has its flange 2l provided with a downwardly turned edge portion 28 supported on the ilange 2Ia of the drain head and the conduit 25a opens to the bottom of the basket which is perforate in character. By this arrangement, and particularly in the case of the flooding of the floor surface or in the event of clogging the apertures of the grating by debris from the floor, water may stillflow through the conduit 25 directly to the' outlet. Also in the event the apertures of the basket become clogged water may flow through the by-pass conduit 25a.

Fig. 6 is an alternati-ve' arrangement of the structure shown in Fig. 5 and includes the vertical conduit 25a. In this arrangement however the basket 2Gb is supported by the drain head as indicated at 21a rather than by the flange 2 la shown in Fig. 5 butin both the structures of Fig. 5 and Fig. 6 the flange of the basket is spaced about its major width from the flange of' the drain head.

Seepage may be provided for in the forms of the invention shown in Figs. 5 and 6 by means of channels 20a formed in the under surface of the flange thereof as shown at l3a in Fig. 2.

In either of the forms shown in Figs. 3 and 5 the body 3b in Fig.A 3 and the body 3d in Fig. 5 have the bolts 3e and 3f below the respective flange 3g or 3h rather than above the correspond'- ing flange as shown in Fig. l. In the arrangement shown in Fig. 1 thev retaining bolts enter the caulking space 6 and are subject to breakage due to the caulking being hammered forcibly to place. In the form shown in Figs. 3 and 5 the bolts are not subjected to such strain by introduction of the caulking.

In the form of the invention shown in Fig. 4 the flange 24 being integral with the body 3c will prevent introduction of the caulking between the upper end of the outlet conduit and the body. Therefore in the use of the device shown in Fig. 4 the outlet conduit lb would have a cement or other plastic applied to the exterior of the conduit lb and the member 3c assembled therewith while the cement or plastic material is in soft condition whereby portions of the caulking material would be forced into the space between the conduit l b and the body 3c in forcing the body to final position.

The preferred form of the invention is shown in Fig. 3.

In either of the structural forms shown the same object is obtained namely, the floor drain may be positioned at the time the iloor level is determined and prior to the pouring of the concrete and subsequent to the breaking or cutting off the upper end of the outlet conduit, it being understood that the shortening of the outlet conduit la when necessary be done at the time the floor level is determined and prior to the positioning of the drainage tting on the conduit.

Once the fitting is assembled with the conduit, subsequent cleaning of the floor drain may be readily accomplished without interference with the drain conduit.

It is believed evident from the foregoing description that the various features and objects of the invention are attained by the structures described'.
