WASTE-PIPE-CLEANING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 576,507, dated February 2, 1897. Application filed January 10, 1896. Serial lilo. 575,042. (No model.)

To all w/Lom/ it may concern/.-

Be it known that I, WILLIAM A. McCLnL- LAND, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Waste-Pipe-` Cleaning Apparatus; and Ido hereby declare that the following is a full, clear, and exact description of the invention, such as will en able others to make and use the same, reference being had to the accompanying drawings, forming a part-of this speciiication.

The objects of my invention are, first, to employ the hydraulic force of a stream of water under pressure in connection with the receiver for the cleaning of waste-pipes; second, to adapt the apparatus to waste-pipes varying in diameter.

My invention consists in the novel construction and combination of parts, such as will first be fully described, and specifically pointed out in the claims.

In the drawings,Figure lis a view in perspective of my improved waste-pipe-cleaning apparatus with the water-supply pipe, also showing a sink, with a portion of the side of the sink removed, and the apparatus applied to the waste-pipe. Fig. 2 is a horizontal side view of the apparatus,shown connected with a street waste-pipe and with the apron clamped to the pipe. Fig. 3 is a Vertical sectional view in detail, showing the elastic receiver within the waste-pipe, the apron and clamp, and the hollow handle connected with the receiver. Fig. 4 is a detail view of the apron.

Similar letters of reference indicate correspending parts in all the iigures.

Referring` to the drawings, Arepresents the elastic receiver, which consists of an inverted cupmade of rubber and conforming exteriorly to the figure of a cone. In the apex a of the receiver A is a threaded opening eX- tending in the direction of the axis of the receiver, in which opening` is iitted the screwthreaded end b of the hollow tubular handle I5. The tube B is made short in length, and

the other end Z2 of said tube is internally screw-threaded, and to said end is fitted the screw-thread end c of an extended portion of the handle C, which is made up of wood and closes the end Z9 of said pipe B. In the side of tube B near the end portion of the handle C is an opening b2. To the outer side of said tube, around said opening, is attached rigidly one end d of a Water-conducting pipe E, which is bent at an angle in close position to the sides of the tubular handle B,and the other end of said pipe is extended in a vertical direction, and in said end is a back-pressure valve e. To said upper end dIV of pipe E is attached by a union-coupling f one end of a rubber or elastic hose F, the other end of which hose is connected with the water-supply pipe G of a street water-supply system.

On'the base F is an elastic collar or spool II, upon which is a clamp h, which clamps the end of the hose F to the water-supply pipe G near spigot g. On the tube B, a short distance above the point of attachment with the receiver A, is a disk Z, upon the upper side of which disk is a sleeve t', which extends around pipe B. The said disk Z and sleeve t', which are in one piece, are also for the purpose of removal cast in two parts in a vertical direction, and upon the said disk are lugs '17, opposite in position, which are provided with securing-bolts t2. Upon the separate parts of sleeve t" are lugs i3, opposite in position, which are provided with securing-bolts t4.

For the purpose of cleaning Waste-pipes, such as pipe M, leading to the sewer and larger drain-pipes, the connections are removed, so as to expose the upper open end of the pipe, over which is placed a rubber gasket L, to the outer edge portion of which is connected a circular apron Z, the apron and gasket being made in one piece. The receiver A, which is nearly of the same diameter as the pipe M, is inserted within said pipe, the apron Z extending around the outer side portion of said pipe. Aclamp N, in two separate parts, is itted over the apron Zand around the said end portion of said pipe, which parts of said clamp are provided with lugs n n and secured by the bolts n. Upon the separate parts of the clamp A are lugs n3, which extend over the edge of the disk Z and hold the disk in position.

In the operation of the apparatus the receiver A is placed within the sink K and eX- tending around the Waste pipe aperture. The operator seizes the handle C with both hands and bears downwardly with sufficient IOO force to compress the receiver A, which contains air, and the sides expand and drive the air forcibly through the waste-pipe. The pressure is then released from handle C and the elasticity of the receiver causes a reverse movement. The spigotg is then turned so as to admit the flow of water from the sewage-pipe G under pressure, which iiows through hose F, pipe D, into the tube B and receiver A, thence to the waste-pipe, the receiver A filling rapidly and containing an eX- cess of water which is above the opening to the waste-pipe. Pressure is then applied to the handle C downwardly, and this action causes the receiver to yield and force the water within its sides through the waste-pipe with great force, the return of the water up the pipe B and CZ being checked by the backpressure Valve e. The pressure is then released upon the handle C, and the receiver is expanded again with water and the movement upward and downward of the handle C continued alternately, forcing the water with great force through the waste-pipe and cleaning the sides of the pipe thoroughly and effectively,the water receiving an impetus si milar to that effected by the action of a hydraulic ram and carrying out of the pipes all waste obstructions.

In the cleaning of waste-pipes, as shown in Figs. 2 and 3, the handle is operated in the same manner, the surplus water in the pipes receiving the pressure of the water passing through the receiver under pressure.

Having fully described my invention, what I now claim as new, and desire to secure by Letters Patent, is-

1. In a waste-pipe-cleaning apparatus, consisting of an invertedelastic cup, and a handie connected with said cup, the combination of a pipe-closing cover extending around said 4o handle, substantially as shown and describedf 2. In a waste-pipe-cleaning apparatus, the

combination with the waste-pipe of an inverted elastic cup, a handle connected with said cup, a pipeclosing cover extending 45 around said handle and a gasket between said cover and said Waste-pipe having an apron extending around said pipe, substantially as and for the purpose described.

3. In a waste-pipe-cleaning apparatus, the 5o combination with the waste-pipe of an inverted elastic cup, a handle connected with said cup, a disk on said handle and a gasket between said disk and waste-pipe, having an apron extending around said pipe, and a clamping device for said apron, substantially as shown and described.

4. In a waste-pipe-oleanin g apparatus, the combination with the waste-pipe of an inverted elastic cup, a tubular handle con- 6o nect'ed with said cup at one end, and a flexible liquid-cond u ctin g pipe connected with the other end of said pipe, having a back-pressure or check valve, a disk on said handle and a gasket between said disk and said waste-
