.l leteir'ing new to the are hi h, and first to Figs 1 and '2, a floor drain 1 aceer mg to theinventieh amount of a fluid or liquid. The fluid or liquid to'be drained may enter the compartment '16 through a grating '3 having 'a plurality of apert e; 23 'inits'spherical bottorn and being removably placed; on a shoulder 80 of said compartment 16. The wallsof the floor drainIoonsist preferably ofone piece and-includea partition-2, aportion of which dips into the liquid contained in the cornpartment 16. The compartment 16 communicates with a downwardly extending outlet or pipe 4 which may be 1 used for connection with a sewer line. 7

An. opening 5 communicates with the portion of the compartment 16 behind the partition 2 and with the outlet 4. Said opening 5 may be used for cleaning purposes.

Aeeeiaihg te the mhedihieht shown in Figs. -1 a a 2, the recesses 9 are arranged opposite each other. The inclined rear surfaces of said recesses 9 are offst'icii "a width and length tliat they ermit an abutting eii' agemerit with a tool such as a chisel, for lifting the eaver by engagement of the tip of the tool with the lo tii'er s face of the laterally projecting edge-15 of "the sever 7. Also, the angle of the inclination of said 'in'eli-iied iear surface is chosen in such 'a why tha'tit inay sei'V-e an abutting surface for the tool when the latter'is iise'd above. In order to facilitate matters, the flail 8 at the cover '7 is provided with notches 10, or'the opposite "the recesses "9, which notches 19 may re'c ei'i e the tip 'of the tool leveling np'the cover 7.

The oiitl'etfi of the floor drain 1 is attached to the bowl-shaped liquid receiving compartment 16.

The floor drain 1 has an upper rhn provided witl'i'a catehiiigree've 19 arranged for receiving Water'br liquid losin'g r'tiie sle the. latterf-ioirl co'n mg 1-, the rim or a plilrality of slots'22 spaced from each other and-allowing the trickling water to reach the groove 19. Preferably the ledge 21 is 5 millimeters high and 3 millimeters thick. a a

The operation of the floor drain is as follows: The liquid collecting on the floor flows through the slots of the cover 3 shaped as a grating and 'collectsin the lower portion of the compartment 16. If sufi'icient liquid has accumulated therein, the upper level thereof rises above the upper edge of the partition 17, the channel provided between the two partitions 2 and 17 forming a water seal within the bowl 16. When the Water level rises beyond the upper edge of the partition 17 the water flows into the outlet or outflow pipe 4 from which it is conveyed by its own weight into a conduit (not shown), for example sewer line, or the like. The sealed cover 7 prevents any gases separated from the liquid, such as ammonia, from escaping through the opening 5.

However, when it is intended to clean the floor drain and/or outflow pipe 4 the cover 7 may be temporarily removed from the opening by inserting a tool or tools such as a chisel or the like into the recesses 9 for levering up the cover 7 and removing same'temporarily.

The embodiment shown in Figs. 3 and 4 substantially corresponds to that shown in Figs. 1 and 2. However the four recesses 9 of the embodiment shown in Figs. 1 and 2 are replaced by a chamfered edge 109 (Figs. 3 and 4) of the frame 11 of the floor drain 1 surrounding the rim of the cover 7 along its entire length. Again the cover 7 resting on the top of the inner Walls 25 and entering the groove 6 by its downward flange 8 may be levered up (for opening the passage 5) by means of one or more tools (chisels or screw-drivers, for example) inserted at suitable places into the recess 109 and engaged with the lower side of the projecting edge 15 of the cover 7. Preferably two tools inserted into the recess 109 at opposite sides of the cover 7 are used for lifting up the latter. If desired, however, the recess 109 and the corresponding projecting edge 15 must not necessarily surround the entire cover 7. For example the recess 109 and the corresponding projecting edge 15 may be arranged only at two opposite sides of the frame 11.

According to the embodiment of a closure member shown in Fig. 5 of the drawing, the cover 207 to be inserted into the aperture of the frame 11 of the floor drain 1 so as to prevent odors from escaping is provided with beveled corners 212 leaving a substantially triangular space 226 at the corners of the groove 6. Furthermore the cover 207 is provided with undercuts 227 at said beveled corners 212. Thus if the cover 207 shall be levered up for opening the aperture of the frame 11 for cleaning purposes, one or more tools 13, for example chisels, are inserted into the triangular spaces 226 for engagement of their tips with the surfaces of the undercuts 227. Thus, the cover 207 may be readily removed from the aperture of the frame 11. Instead of arranging four beveled corners 212 and four undercuts 227 as shown in Fig. 5, only two beveled corners 212 and two undercuts 227 could be arranged at opposite corners of the cover 207; such an arrangement could also be sufficient for lifting the cover by means of tools, such as chisels or screw-drivers.

Fig. 6 illustrates a hollow auxiliary body 329 which may be placed into the groove 6 of the floor drain 1 shown in Fig. 1 upon removal of the cover 7, if so desired. The auxiliary body 329 has an opening 305 arranged at a high level which may be closed by a cover (not shown) similar to the cover 7 shown in Fig. 1. The wall 311 of the auxiliary body has a plurality of inclined recesses 309 corresponding to the recesses 9 of the frame 11 shown in Fig. 1. The use of the auxiliary body 329 for an elevated arrangement of the cleaning opening 305 (Fig. 6) above the grating 3 (Fig. 1) of the floor drain is of special advantage in lavatories as this protects the attendant from contacting urine flowing or collecting in grooves.

I have described hereinbefore preferred embodiments of my invention, but it is understood that this disclosure is for the purpose of illustratiomand that various omissions and changes in shape, proportion and arrangement of parts, as well as the substitution of equivalent elements for the arrangements shown and described may be made without departing from the spirit and scope of the invention as set forth in the appended claims.

What I claim is:

1. A floor drain comprising walls defining a bowl portion, a substantially vertical downwardly extending discharge conduit portion connected to the upper end of one side of said bowl portion, a top portion above said bowl portion having side by side pair of openings including an inlet opening in alignment with said bowl and an access opening in alignment with said discharge conduit portion, said top portion including a downwardly extending baffle wall spaced from the side of said bowl adjacent said discharge conduit portion andextending downwardly into said bowl to a position spaced from the bottom of said bowl whereby to define a substantially U-shaped passage from said inlet opening in said cover to said discharge conduit portion, a floor level flange extending around theoutside of said drain at a location spaced downwardly from said cover portion, said flange including spaced upstanding portions with small openings therebetween to trap waste material thereon, said flange being sloped downwardly toward said bowl, at least one opening in said bowl at the inner end of said flange, said cover including an interior shoulder extending around said inlet opening and a shoulder extending around said access opening, a perforated drain plate positioned on said cover inlet opening interior shoulder and closing said inlet opening, and .a cover plate closing said access opening.

2. A floor drain according to claim 1 wherein said access opening has an upstanding peripheral wall at the inside of said shoulder portion and including a removable extension portion having walls which are positioned in said access opening and rest on the shoulder thereof on the outside of said interior upstanding peripheral wall.
