To (1, whom, it may curl/corn.-

Be it known that I, FERDINAND FINK, a citizen of the United States, residing at Newark, in the county of Essex and State of New J ersey, have invented certain new and useful Improvements in Automatic Hose-Cleaning Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

This invention relates to the cleaning of tubes or pipes, and more particularly to the cleaning of hose as it is done by brewers and the like, the objects of the invention being to provide a device to which the opposite ends of the hose may be attached and water driven through said hose in alternate directions and carrying with it a brush; to thus clean the hose with a plentiful supply of constantly-renewed water, which keeps both brush and interior surface of the hose flushed; to mechanically loosen the dirt by the moving brush; to utilize the water-pressure for driving said brush; to obtain an automatic operation of the device whereby it needs no attention other than coupling on and uncoupling the hose at the beginning and end of the operation; to thus reduce the labor and expense of cleaning hose; to secure more perfect cleansing, and to obtain other advantages and results, some of which may be hereinafter referred to in connection with the description of the working parts.

The invention consists in the improved hosecleaning device and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like figures of reference indicate corresponding parts in each of the several figures, Figure 1 is avertical central longitudinal section of my improved device. Fig. 2 is a crosssection of the device upon line 0:, Fig.1 and Fig. 3 is another cross-section taken upon line y, Fig. 1. Fig. 4 illustrates a form of brush adapted for use with my improved device; and Fig. 5 is a cross-sectional view upon line 1/, Fig. 1, illustrating the flow-valve more clearly.

In said drawings the body of my device is shown as comprising a longitudinal tubular part 3 with end portions 4-. 4 and a middle l portion 5 of larger diameter than said end portionsst 4. Said middlcpartis divided by atransverse partition 11, and a water-supply duct 6 communicates by branches 7 7 with the said end portions 4 of the body part and by smaller ducts 8 8 with the middle portion 5 on opposite sides of its partition 11. Each of said end portions st is threaded at its extremity, as at 9, to receive an end 10 of the hose, and obviously either one length or any number of lengths of hose connected together may be applied to the opposite ends of my device, as shown in Fig. 1, so as to form a complete ring or circuit through which the water passes. The coupling ends of the hose may be either screwed directl y to said threaded ends 9 of the device or any suitable and well-known form of intermediate couplings may be employed to facilitate the attachment of different sizes of hose, as desired. Within the said middle large portion 5 of my improved device and on opposite sides of the said partition 11 are pistonheads 12 12, which are rigidly connected by rods 13, extending slidably through the said partition 11. Each piston-head 12 carries at its outer side a stem or rod 1 1, projecting centrally and axially into the adjacent end portion 4 of the body part of the device and having in said end portion a slide-valve 15. Preferably each slide-valve comprises an inner solid disk 16 and an outer spider 17, both said parts having continuous unbroken pcripheries fitting against the walls of the tubular portion 4: and being separated by an annular space 18, as shown in the drawings. ()ther constructions might be employed, however.

The port 19 of the water-supply duct 7 and a discharge or exit port 20 in opposite sides of each portion 4 of the body part are disposed at such points along the length of said end portion that when the former is closed by the disk 16 of the slide-valve the other or discharge port is open to the middle open space 18 of the valve and similarly when the spider 1'7 closes the said exit-port 20 the inlet-port 19 is open to the space 18 of the valve.

Each stem or rod 1 1 and its slide-valve 15 are centrally bored to slidably receive each a shaft 21, which shafts are in alinement with a corresponding shaft 22, passed centrally through the partition 11 and sliding in a stufling-box 23. Upon the said shaft 22 at each of the opposite sides of the partition 11 is mounted a discous slide-valve 24:, fixed upon the shaft and perforated to receive the rods These slide-valves 24: are adapted to govern the admission of water by the ducts 8 8 to the middle portion 5 of the body of the device, the distance between said disks differing from the distance between the ports 25 of said ducts by at least the diameter of said ports, so that as one port is covered the other is uncovered.

As the device is shown in the drawings the port 19 of the water-supply duct 7 at the lefthand side of Fig. 1 is closed by the valve 15, while the discharge-port 20, leading from the tubular end portion 4, is open. The port 25 of the inlet 8 to the large central portion 5 of the device at the same or left-hand side of the partition 11 is open; but obviously the water-pressure entering thereth rough cannot effect the adjacent slide-valve 15, since the outer end of the same is engaging the end 10 of the hose connection as a stop. At the other end of the machine or right-hand side of Fig. 1 of the drawings the inlet 25 of the duct 8 to the middle portion 5 of the body partis closed by its valve 2 1 and the watersupply duct 7 to the adjacent end portion 4 is open, since the solid disk 16 of the slide-valve lies inside the port 19 of said duct. The spider 17 at the same time is closing the discharge-port 20, and thus the watersupply will be directed into the hose in the direction shown by the arrow and passing around the hose throughout its entire length escape at the open discharge-port at the opposite end of the device.

Within the hose is placed a short cylindrical brush 30, preferably comprising a rubber body portion 31, in which tufts of bristles 32 are set, so that the whole brush is somewhat flexible longitudinally. Flexibility of the brush may be otherwise secured, however, in any manner known to the art. The ends of the body portion 31 of the brush are flared and hollowed out, as at 33, so as to present cuplike extremities to the water-pressure. This brush is inserted in the hose before coupling to my improved device, and the water-pressure forces the brush ahead of it from one end of the hose to the other. With the parts as shown in Fig. 1 this would be from the right-hand end of the machine around to the left-hand end of the machine, where the brush would engage the end of the shaft 21. The shock of such engagement is transmitted to the middle shaft 22, and said shaft is thereby slid to reverse the positions of its two slidevalves 24, so that the one at the right-hand end of the figure will open the port of the inlet-duct 8, while the corresponding port at the left-hand end of the drawing will be closed. ater then enters upon the righthand side of the partition 11 and acts upon the piston-head 12 to force the same away from said partition. This slides the valve 15 at the right-hand end of the drawing to close the port 19 of the water-supply duct 7 and open the exit 20, while by means ofthe rods 13 the slide-valve 15 at the opposite end of the machine, or at the left-hand side of the drawing, is simultaneously slid to effect an exactly opposite result-namely, a closing of the exit-port 20 and opening of the port 19 of the water-supply duct 7. All the parts are now exactly reversed from what is shown in Fig. 1 and water runs through the hose in the opposite direction from at first or as indicated by the arrows, carrying with it the brush 30, which when it reaches the opposite end engages the shaft 21 to eflect another change. This alternation is kept up automatically as long as the Water-pressure remains in force, and obviously the cleansing of the hose is a wholly mechanical operation to a great saving of labor and expense. In fact, it is only necessary for the workman to couple the hose to the opposite ends of the device, turn on the water, and turn it off again when he thinks the hose is sufficientl y claimed.

It will be understood that stops suitably regulate movement of the center shaft 22, so as to bring the governing slide-valves 24 into proper relation to the ports 25 for instance,

by having the ends 26 26 of the hubs of said slide-valves engage the partition 11. Similarly the stops provided by the hose-coupling connections or otherwise are so disposed as to limit movement of the water-controlling slidevalves 15 to proper relation to the

ports

19 and 20.

The chambers of the middle portion 5 for the piston-heads 12 are each provided with relief-ports 34 35, one of which, as 34, is so disposed as to be covered and closed by the governing slide-valve 24: when the inlet-port 25 is open. The other relief-port 35 is located nearer the outer end of the chamber and adapted to be covered and closed by the piston-head 24 in its outermost position and exposed or opened when the said head slides inward.

It will be noted that in the operation of my device the impacts of the traveling brush against the shafts 21 simply slide said shafts longitudinally to move the governing-valves 24. These impacts do not affect the slidevalves 15 except as they move the governingvalves 24 to admit water-pressure against one or the other of the piston-heads 12, carrying the valves 15.
