SEWER-CLEANING MEANS.

Specification of Letters Patent. 7 Patented A r, 20 1915 Application filed December 10, 1914. Serial No. 876,429.

To all whom it may concern:

Be it known that I, ADOLPH BORNEMANN, a citizen of the United States, and a resident of Bettendorf, county of Scott, State of Iowa, have invented a new and Improved Sewer-Cleaning Means, of which the following is a full, clear, and exact description.

My invention relates to a means for cleaning sewers by flushing the same with water under pressure, and the prime object of my invention is to provide a means whereby to hold the pressure of the flushing head in the sewer pipe and cause a sudden ejective impulse of the flushing water, whereby to eiiectively remove any collected matter from the sewer.

In carrying out the invention the sewer pipe is capped at one end and. the capped end connected with a flushing pipe to conduct water under pressure. Near the opposite end of the sewer pipe a quick action valve is employed, and risers are connected with the sewer pipe between the capped end and the quick acting valve, which constitute sewer intakes. The intakes are fitted with valves adapted to be closed for holding the pressure of the flushing head. The quick action valve is normally maintained open by a spring, and a lever is arranged in connection with the said valve for closing the same against the tension of the spring, so that upon a sudden release of the lever the spring will instantaneously open the valve and cause a sudden ejective impulse of the flushing water. In addition to the risers other intakes may lead to the sewer from a cellar basin and drain pipe, and from a closet, or the like, as the requirements may necessitate.

The invention will be particularly explained in the specific description follow- 111 Iieference is had to the accompanying drawings forming part of this specification, in which similar characters of reference indicate corresponding parts in all the views, and in which: I

Figure 1 is a side elevation of a sewer embodying my invention, showing a series of intakes leading thereto; and Fig. 2 is a sectional plan View on the line 2-2 of Fig. 1.

In carrying out my invention in accordance with the illustrated example, the sewer 10 is composed of suitable pipe sections having the usual flanges 10*. At one end the sewer pipe 10 is closed by a cap 11, and into said cap leads a flushing pipe 12 adapted to conduct flushing water under pressure to the sewer pipe. A suitable valve 12 controls the flushing pipe 12.

Near the outer end of the sewer pipe, or that end opposite the cap 11 and flushing pipe 12, I arrange a quick acting valve generally designated by the numeral 13, and shown in the form of a gate valve. Around the stem of the valve 13 is a compression spring 14 normally tending to maintain the valve open. For closing the valve a lever 15 is supplied engaging the valve stem by a slot and

pin connection

16, 17, between the ends of the lever, said lever being fulcrumed at one end as at 18 on a bracket 19 in rigid relation to the casing of the valve 13.

Leading to the sewer pipe 10 are intakes 20 in the form of risers which connect with flanged Y-branches 21 of the said sewer pipe. The intake risers 20 are provided in suitable number, there being two shown in the illustrated example. Each riser is fitted with a valve 22, preferably a gate valve, the numeral 23 indicating the wheeled stems of the valve.

In practice the valves 22 are adapted to be closed when it is desired to flush the sewer, the closing of the valves serving to hold the pressure 01": the flushing water, it being understood that when flushing water is to be turned on, the lever 15 is depressed so as to close the valve 13, thereby confining the water under pressure until the sewer pipe is filled. By suddenly releasing the pressure on the lever 15 the spring 14 will instantaneously open the valve 13, thereby causing a sudden ejective impulse of the flushing water through the sewer whereby to effectively disturb any collected matter and carry the same outward with the flushing water.

I have shown the sewer pipe as arranged beneath the floor 24 and the risers fitted with flanges 25 at the flooring. In addition to the intake risers 20 various other intakes may connect with the sewer pipe, as will readily be understood. In the present example I have shown a cellar basin 26 in the floor 2 1; from said basin leads downwardly a drain pipe 27, which may be provided with a trap 28. Connection is-made between the drain pipe and the sewer pipe 10 in any suitable manner, as by a Y-branch 29. The drain pipe is provided with a suitable gate valve, or equivalent to hold the pressure of the flushing water when required. The illustrated example also includes a closet 81 connected by a pipe 32 to thesewer pipe 10 by. a branch 33, said pipe 32 having a cut-oil valve 34:. I

In practice, the pressure pipe 12 may be fitted, at any desired height, with a pressure-reducing valve, one type of which is in dicated conventionally at 35.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent, is:

1. A sewer and cleaning means therefor, comprising a main sewer pipe, flushing means connected with said pipe and adapted to discharge water thereinto under pressure, a quick acting automatically opening outlet Valve and actuating means therefor adjacent to the outlet end of the sewer pipe, whereby to impart a sudden ejective impulse to the sewer contents under pressure of the flushing water upon a quick opening of the said valve when released, and an intake leading to said sewer between the flushing means and the quick acting valve, said intake having a valve to effect a closure of Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, 7

the intake to hold the pressure of the flushing Water until the outlet valve is opened.

2. A sewer and cleaning means therefor, comprising a main sewer pipe, a cap on one end of the sewer pipe, a flushingpipe leading intothe sewer pipe through the said cap to conduct water thereto under pressure, a valve in the sewer pipe near the outlet end,

a spring normally tending to maintain'said valve open and adapted to instantaneously open the valve when closed, whereby to effeet a sudden ejective impulse of thesewer contents, a valve-closing leveroperatively engaging said valve to close the same in opposition to the tension of the spring, and risers connected with the sewer pipe between the fiushing pipe and the said valve, said risers constituting sewer intakes and being fitted with cut-otf valves to be closed or Washington, D.
