1 Claim.

This invention relates to shower pipe cleaners for pulp, paper, board, and shingle machines and has for an object to provide a novel cleaner plug in the shower pipe and valve controlled pipes for reversing the ilow of water'through the shower p-ipe to alternately move the cleaner plug from one end of the shower pipe to the other to thereby effectively clean the jet openings in the shower pipe in minimum time and without manual exertion.

A further object is to provide a device of this character which will be formed of a few strong simple and durable parts, which will be inexf' pensive to manufacture and which will not easily get out of order.

With the above and other objects in view the invention consists of certain novel details of cony struction and combinations of parts hereinafter yfully described and claimed, it being understood that Various modifications may be resorted to within the scope of the appended claim without departing from the spirit or sacricing any of the advantages of the invention.

In the accompanying drawing forming part of this specification,

Figure 1 is a longitudinal sectional view of a wire covered cylinder used in machines of the class described and showing a shower pipe and cleaner plug therein constructed in accordance with the invention.

Figure 2 is a detail sectional view drawn to enlarged scale, and showing the plug at the opposite end of the shower pipe from the position shown in Figure 1.

Figure 3 is a detail perspective view of the cleaner plug.

Figure 4 is a side elevation of a shower pipe and valve controlled supply pipe and showing a modied form of cleaner plug.

Figure 5 is a side elevation, with parts in section, showing two valves, opening oppositely, in lieu of the three-way valve illustrated in Figures 1 and 4.

Referring now to the drawing in which like characters of reference designate similar parts in the various views, IU designates a cylinder of the type used in pulp mills and the like, the same being covered with wire screen I I, and being equipped with hollowed journals I2 which are mounted in pedestals I3 or other suitable supports.

In carrying out the invention a shower pipe I4 is mounted in the cylinder vto extend longitudinally thereof close to the screen Il and is provided with elbows I3 at the ends into which short pipes I4 are fitted and these latter are also equipped with elbows I5 which receive pipes I6 that extend through the hollow journals I2.

In order that water may be let into the shower .pipe from either end and sprayed against the wire screen through the jet openings Il in the shower pipe, a supply pipe I8 is provided with a conventional three-way valve I9 to the housing of which are connected branch pipes which extend oppositely to each other and are equipped with elbows 2|. Short pipes 22 are connected together by a coupling 23, and these pipes are connected to the elbows 2I and to elbows 24 that are secured to the ends of the beforementioned pipes I6 which extend through the hollow journals I2.

Mounted to slide longitudinally in the spray pipe is a cleaner plug for preventing clogging of the jet openings I'I. in Figure 3 to comprise a pair of discs 25 and 26 having passages 2l formed therein. These discs are xed on a short rod 28. A pair of disc valves 29 and 30 are slidably fitted on the rod and are of suicient size to close the passages 21 in the discs 25 and 26. Stop collars 3| and 32 are xed to the rod and limit opening movement of the disc valve 30.

In practice when the three-way valve I9 is turned in one direction water will ilow as indicated by dotted lines in Figure 1 whereupon the valve 29 will be forced open and moved against a stop collar so that continued flow of the Water will push the cleaner plug endwise to the opposite end of the shower pipe during which time the cleaner discs 25 and 26 will wipe over the jet opening I'I and remove clogging material. By reversing the three-way valve the flow will be as indicated by arrowheads in Figure 2 so that the cleaner plug will be moved in a retrograde direction to the opposite end of the shower pipe.

A modified form of the invention is shown in Figure 4 in which the shower pipe 33 is provided with supply pipes 3G and 35 at the ends through which the water may be fed in either direction to the shower pipe. In this embodiment of the invention a supply pipe 36 is equipped with a three-way valve 3l. The pipe 34 enters one end of the housing of the valve. A pipe 38 enters the other end of the housing and is connected to a pipe 39 which in turn is connected to the pipe 35.

By turning the three-way valve in one direction the flow in the shower pipe will be through the

pipes

39, 38 and 35 as indicated by the arrowheads and when the valve is reversed the flow will be reversed and will enter the shower pipe through the pipe 34.

The cleaner plug is best` shown The cleaner plug 40 illustrated in Figui- 4 may be simply a wood plug having an axial opening to receive a rod 4I. The plug is centered on the rod by means of stop nuts 42 which are threaded on the rod outside of the ends of the plug. The operation of the plug is the same as previously described, the plug when moved in either direction by flow of Water serving to Wipe over and open the jet openings 43 of the shower pipe.

In Figure 5 there is shown a modified form of valve which may be used in lieu of the three-Way valve. In this modied form of Valve a pair of plug valves 44 and 45 are mounted so that their 1 openings 45 and il will turn respectively opposite to each other so that when one valve is open the other valve is closed and thus flow from the; supply pipe 48 through the branch pipes 49 and 50 to the shower pipe, may be reversed.

For simultaneously manipulating the valves 44 and 45 the handles 5I and 52 of the valves are extended parallel to each other and are connected by a link 53 so that both valves will move in unison.

From the above description it is thought that the construction and operation of the invention will be fully understood Without further explanation.

What is claimed is:

A cleaner member adapted to be reciprocated longitudinally in a vpipe by the reversal of liquid oW, comprising, a rod, spaced discs on the rod of substantially the same diameter as the bore of the pipe to be cleaned, said discs having passages therethrough, Valves slidably mounted on the rod-between said discs for controlling said passages, and stopv collars on lthe rod intermediate said valves and against which said valves abut When actuated away from said discs to establish said passages in open condition.
