COVER FOR FLOORr-SUMPS.

Application filed March 1, 1919.

To all whom it may concern:

Be it known that I, EDWARD W. N. Boosnr, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Covers for Floor-Sumps, and declare the followingto be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to covers for floor sumps, and its object is to provide a simple and efficient construction of a cover for a sump formed of a crock body, the cover being adapted to be connected with the vent and discharge lines and provided with means of calking the said lines to the cover and avoiding the necessity of forming apertures in the crock body for such purpose as has heretofore been the usual practice. In previous sumps formed of crock a fiat cover has been provided having a reservoir in the nature of a trap preventing a backfiow of gas from the crock but, in such previous constructions, it is necessary to break the side of the crock for introduction of the vent and overflow lines, etc., resulting oftentimes in the fracturing of the body and also increasing the cost of installation. An object of this invention is to provide a metal cover having apertures by means of which the necessary vent and overflow lines, etc., may be calked in position on the cover as is hereinafter more fully described and claimed. The preferred form of the invention is shown 1n the accompanying drawings in which Figure 1 is a plan view showing my improved. cover in position on a crock body.

Fig. 2 is a vertical central section thereof.

Fig. 3 is a vertical section showing an alternative form of construction.

Heretofore it has been usual to place the upper end of the crock sump in the floor. In the use of my improved cover, the crock body 1 is positioned below the floor line as shown clearly in Fig. 2, and a cover 3 is pro vided therefor having a circular base portion fitting the shoulder at the upper end of the crock and an offset tubular portion 4: extending upward to the floor surface. This portion 4 has an upper enlarged end 5 adapted to receive the usual trap member 6 and fora-envious cover plate '7 therefor as Specification of Letters Eatent.

- shown. The vertical axis of this upright tubular portion 4 is eccentric to the axis of the cover as will be clearly understood from Fig. 1, and the cover on one side of the tubular portion is provided with a series of apertures 8 having a recess formed there' about for the lead calking 9 by means of which a pipe 10 insertible through the aperture may be calked in position to prevent an escape of water through the pipe aperture. The number of apertures 8 may be varied depending on the number of pipes calked in the apertures 8 therefor, the member 3 is covered with cement 16 sealing the crock at the upper end and preventing an escape of water therefrom. It is also to be noted that the tubular member 4 or 15, as shown in Figs. 2 and 3 respectively, may be provided with a trap reservoir as is-shown in Fig. 2, or with merely the ordinary grating 7 as shown in Fig. 3, there being many uses for the device in which a trap reservoir is unnecessary. It is therefore to be understood that the type of cover for the tubular portion whether integral or separate from the cover member is not material to this invention.

This sump is particularly useful in garages and places where oil and gasolene or grease from sinks, etc., may Wash into the sump and, for the purpose of recovering oil, etc., I provide the cover with a pump 13 (which may be of any approved form) hav ing a barrel extending below the lower surface of the cover 3. By this means, oil

may be drawn off from the sump previous to possibility of its overflow through the discharge pipe 10 as will be readily understood. By means of the vent mentioned, the gaseous vapors arising from the sump may be dis charged therefrom, the trap reservoir 6 preventing the discharge through the grating 7 The member 4: may be made integral with the" cover member 3 shown in Fig. 2

separate therefrom as indicated in Fig. 3.

I In this latter construction the cover 3 is provided with an aperture 14 at one side of the center of the cover, and a member 15 similar in all respects to the member A may be calked in position on the cover as shown. The cover in other respects corresponds to the cover shown in Fig. 3.

By the construction of a cover as described, a crock sump may be utilized providing an inexpensive installation that is fully as efficient as an all metal type.

Having thus briefly described my invention, what I claim is 1. A cover for sumps consisting of a base member having flanged apertures adjacent one side for calking of a pipe member thereto and an integral tubular portion positioned 'eccentrically ol the cover and opening therethrough, the said tubular portion being adapted to receive an apertured cover, and a trap reservoir therebeneath.

2. A cover for floor sumps consisting of a tubular portion opening through the floor and provided with the usual trap reservoir at the mouth, and a cover member at the loWer end for the sump body adapted to be calked thereto and provided with flanged apertures for discharge piping, and an aperture for attaching a pump or the like thereto.

3; A sump cover comprising a cover member having a comparatively large aperture positioned at one side of the center of the cover and a series of smaller apertures through which the piping may be connected,

a tubular member calked to the said aperture, the tubular member extending upward to the floor line and provided with the usual grating and trap reservoir.

4-. A metal sump cover for crock sumps consisting of a tubular member having the upper end positioned at the floor line and extending therebelow and a base member adapted to be sealed to the end of the crock body, the base member having one or more apertures at one side of the tubular member for introduction of the usual piping, the

, fication.

on one side for connection with a vent line,

the crock being adapted to receive the said base in sealed relation therewith;

6. A cover for floor sumps consisting of a base member havin an aperture adjacent one side for the callring of a pipe member thereto, a tubular portion positioned eccentrically of the cover and opening therethrough and extending to the floorline providing an inlet for the sump, a trap reservoir for the said inlet member, and an apertured hub formed in the side of the tubular portion for the connection of a vent pipe.

7. A floor sump consisting of a crock member having a bell end and a cover member adapted to be (cemented therein, the cover member comprising a base and a tubular portion opening through the base and extendingto the floor line to provide an inlet, the tubular member being eccentric-ally positioned on the said base, and the base being provided with an aperture for calking an outlet pipe thereto.

8. A cover for sumps consisting of a base having flanged apertures adjacent one side for calking pipe members thereto, a tubular portionat one side 01" the apertures eccentrically of the cover and opening through the base, an apertured cover for the said tubular portion, and a trap reservoir therein beneath the cover, In testlmony whereof, I sign thls speci- EDWARD W. N. BOOSEY.
