4 Claims. .(CL182F25) 7 -matic device of this character which is structurally sound, and is capable of being easily taken apart and assembled for repair and replacement purposes.

Other objects and advantages of my invention will be apparent from a reading of the following description of the drawings, wherein for purposes of illustration Ihave showna preferred embodiment of my invention.

In the drawings:

Figure 1 is'a vertical transverse sectional View through the embodiment.

Figure 2 is a horizontal sectional view through Figure 1 taken approximately on the line 2-2 and-looking downwardly.

Figure-3 is a top plan view-of the'strainer.

Figure 4 is a side elevational view of the float.

Referring in detail to the drawings, the numeral 5 generally designates a vertical cylindrical sewer pipe of cast iron which acts as the casing. The casing is provided at its lower end with a portion 6 which is of larger interior and exterior diameter than the upper part of the casing, and the portion 6 is provided with interior screwthreads I which are arranged for mounting the casing and connecting it with the sewer pipe elbow (not shown).

Within the main portion 1 of the casing is a radially inwardly projecting flange 8 which provides a concentric circular opening 9. Below the flange 8 is a sleeve 9' which snugly fits within the casing portion 1'. The lower end of the sleeve 9' is substantially on a level with the lower end of the interior of the casing portion 1', while the upper end of the sleeve 9 fits against the lower side of the interior flange 8. At the upper end of the sleeve 9' is an annular top portion II] which has on its inward edge a thickened vertical flange I! forming a collar which fits within the opening 9 defined by the flange 8 and reaches a point on a level with the top of the flange 8. A cross member which is vertically elongated is arranged across the opening l3 in the collar H for slidably supporting the float structure to be described.

Resting its lower end upon the top of the collar II is a strainer M. This comprises a relaa suitable number-of holes l6. As isobvious-in Figure l, the cylindrical'portion E5 of the strainer is considerably radially spaced from the interior walls of the upper part of the casing portion l, whereby a water receiving chamber I1 is defined. The upper'end of'the cylindrical portion of the strainer is provided with a plate 18 which is considerably larger in diameter than the upper end of the cylindrical portion 55 of the strainer and has its outer edges seated in an annular groove 19 which is radially outwardly formed at the upper end of the casing portion -i. The plate i8 is provided withholes 2!] which are located in a position to empty sewage into the sewage receiving chamber ll, the central portion of the plate 23 over the cylindrical portion I5 of the strainer being imperforate, whereby the sewage is made to pass through and be strained by the-cylindrical portion l5 before it flows through the opening l3 defined by the collar I! into the lower portion of the casing.

The outside of the collar H is milled toprovide an adequate engagement with the opening 9 defined by the flange '8 so thatthe sleeve 9 is properly supported in position.

Slipped into the sleeve 9 and engaging the side walls thereof as well as the lower side of the top Wall in is a compressible washer which has opening at its lower side hemispherical recess 22. A cylindrical passage 23 is provided through the top of the washer and communicates with the opening I 3 defined by the collar I l on the sleeve 9. As shown in Figure 1 the lower end of the washer is approximately on a level with the lower end of the sleeve 9.

For cooperation with the compressible washer 2i and for engaging its hemispherical recess 22 so as to close the vertical passage 23, is a hemispherical hollow float 24 which has projecting axially from its upper side a bifurcated standard 25 whose legs are arranged on opposite sides of the cross member l2 carried by the collar H. A removable pin 26 traverses the upper ends of the legs of the standard 25 and holds between the 'tively small diameter vertical: cylindrical hollow portion l5 which is provided in its sides with legs at this point a bearing member 2'5 which is arranged above the cross member I2 and to rest thereon when the float is in the lower position, as shown in Figure 1. Whenever sewage backs up through the sewer pipe elbow-into the lower end of the casing 5, the float 24 will be carried upwardly by the sewage until it reaches a position in engagement with the washer 2| in the manner described, in which position it will cooperate Although I have shown and described herein a preferred embodiment of my invention, it is to be definitely understood that I do not desire to limit the application of the invention thereto,

and any change or changes may be made in material and structure and arrangement of parts, within the spirit of the invention and the scope of the subjoined claims.

What is claimed is:

1. In a device of the character described, a vertical casing, a strainer in the upper end of the casing, radially inwardly projecting means within the casing defining a passage, an annulas within the casing at one side of said radially inwardly projecting means and having the lower side of its opening formed with a substantially hemispherical concavity, and a float having a substantially hemispherical upper portion, said float being arranged to riseand engage its hemispherical upper portion with said concavityfor closing said passage.

2. In a device of the type described, a vertical casing having a radially inwardly projecting shoulder dividing the interior of the casing into upper and lower compartments and defining a passage therebetween, a vertical tubular member connected to said shoulder so as to be supported above said shoulder, the walls of said tubular member being perforated to strain 'fluid passing from openings in thetop of the casing to said passage, the lower side of said shoulder adjacent said passage having a portion hernispherically concaved to provide a valve seat of unusually large area, and a float valve having a substantially hemispherical upper portion arranged to conformably engage with a major portion of said valve seat to close said passage.

3. In a device of the type described, a vertical casing having a radially inwardly projecting shoulder dividing the interior of the casing into upper and lower compartments and defining a passage therebetween, a vertical tubular member connected to said shoulder so as to be supported above said shoulder, the walls of said tubular member being perforated to strain fluid passing from openings in the top of the casing to said passage, the lower side ofv said shoulder adjacent said passage having a portion hemispherically concaved to provide a valve seat of unusually large area, and a ficat valve having a substantially hemispherical upper portion arranged to conformably engage with a major portion of said valve seat to close said passage, said hemispherically conoaved portion being formed of compressible material whereby close engagement of said float valve with a major portion of the concavity thereof is assured.

4. In a device of the type described, a'vertical casing having a radially inwardly projecting shoulder dividing the interior of the casing into upper and lower compartments and defining a passage therebetween, a vertical tubular member conformably engage with a major portion of said valve seat to close said passage, across member supported in said passage adjacent said shoulder, a pair of arms rising from said float valve and slidably engaging opposite sides of said cross member, and a member joining said arms and engageable with the upper side of said cross member while said valve is in the extreme depressed position for supporting said valve.
