Water Powered Brush Method and Apparatus

This invention pertains to a hydraulic powered turbine brush in a hydraulic line.

More particularly, this invention pertains to a water powered brush method and apparatus operable in a water line, by an off-chute line therefrom by the pressure thereof, and positioned at a point before the water line point of discharge, and without diminishing the water flow discharge therefrom.

Heretofore, as far as known in the use of water powered brushes, a water powered brush has been connected and operated in and by a water line and after the operation of the brush the water motive stream has either been returned to the water source, or the water brush has been at the line discharge point and the water has been discharged through the brush.

Applicant has developed an improved water powered brush method system whereby neither of the heretofore methods are used. His brush is operated by an offset line without interfering with the flow of the water through the main line, where the main line is directed to a given point of discharge such as to a shower head or a hose nozzle or some such use.

Accordingly, Applicant has as a principle object the provision of a water channel offset from a main water channel for operating a water powered brush to utilize the power of the water passing through the offset channel to operate the brush and to return the water to the main channel to permit its ultimate discharge from the main channel discharge outlet point without detracting from the volume of that discharge therefrom.

Another object is the method of providing the steps of an offset water channel from a main water channel to operate a water powered brush by the water flowing through the offset channel and then returning the water from the brush to the main channel for its ultimate flow to the main channel discharge point, and having the offset channel of flexible conduits with the brush secured thereto.

Another object is the provision of an operable valve means at the point of exit of the offset channel from the main channel to control the water flow from the main channel into the offset channel when in one valve position or to close the offset channel to prevent water from entering therein from the main channel when in another valve position.

Other and further objects will be apparent from the following detailed description and explanation of the operation of the preferred embodiment of the invention and from the drawings, in which:

FIG. 2 is a side view of the brush portion thereof.

FIG. 3 is a partial vertical cross-sectional view of the upper pipe and valves of FIG. 1, indicated by the number 3--3 of FIG. 1.

FIG. 4 is a partial cross-section of my water powered brush, taken as indicated by line 4--4 in direction of arrows of FIG. 1.

FIG. 5 is a vertical cross-section of my water powered brush taken on line 5--5 of FIG. 4.

Referring now to the drawings, in the use of my invention with a conventional shower head pipe 10, I provide a U-shaped pipe extension 11 having two right angular coupler arms 12 and 19. The water source enters the pipe end at 10a and flows therein to the left as illustrated. The first, or right as viewed, offset T-coupler 12 opening is provided with an inner manually operated pivoted crank door valve 13, designed to move on its pivot 14 in one position illustrated in full lines of FIG. 3, to completely close the opening 12 thereof, and in another position of pivoted movement of the crank valve 13, illustrated in dotted lines in FIG. 1, to open 12. That crank door valve 13 is at an angle within pipe 11, as illustrated in FIG. 1, to block the flow of the water to the left as illustrated, through 11 and to direct that water flow into the off-chute pipe 12--16 for reason to be explained. A suitable inner notch is provided within 11, not shown, to hold the crank door 13 in the closed valve position shown in FIG. 3, caused by the arm 15 manually moving crank door valve 13 on its pivot 14 into that position there shown.

A flexible water hose 16 is connected to extend the offset T pipe 12 to one end of a conventional turbine housing 31 of a rotary powered brush 17. A return other flexible water hose 18 directs the water from that housing 31 back to the other offset T 19 of the U pipe 11. A spring actuated pivoted door valve 20, normally spiral spring held in the closed position over the opening 19, as shown in FIG. 3, is provided. That spring on valve 20 thereof is a weak spring so as to not interfere with the normal water pressure flow coming thereunder from the rotary brush up through return conduit 18. The return water flow from the brush turbine causes that valve 20 pivoted door to be raised against the spring tension to let the water to be discharged into 11, as indicated by the dotted line position of 20 and the arrow of the water flow of FIG. 1, when the water coming from 10 enters into the water turbine through 12 and 16 as a result of the open position of crank valve 13, as illustrated in FIG. 1. Flutter spring pivot valve 20 is pivoted at 21.

My water powered brush is of conventional construction, having the housing 31 for the water turbine brush operable therein with the water entering the turbine by the inlet connection 16, and the water leaving the turbine at the outlet extension 18 causing a rotation of the rotatable paddle wheel 40 thereof in conventional manner, as illustrated in FIG. 4. Housing 31 has an inverted bearing cup 32 to hold the upper reduced end of the rotatable turbine shaft 39 therein, of the rotatable shaft 34. A floor 33 is suitably secured, as by screw-threading into the lower edges of 31, and the floor has a bearing central recess 33a designed to receive a bearing collar 35 of shaft 34 therein. The turbine paddle wheel has a shaft 34 and it has the collar bearing 35 as an integral part thereof to ride on recess 33a. A packing is provided in 33a for the purpose of water seal in conventional manner. A pin 36 is secured in the shaft 34, as illustrated in FIG. 5, for reason of adaptability of removable screw-securement of the brush 37 to the shaft. The brush 37 has a central upper stud 38 screw-threaded and is adapted for removable insert as shown into the lower end of shaft 34, upon manual holding of the shaft by pin 36. This water powered brush is of conventional turbine design.

Conventional water fins or blades 40 substantially fill the space within the housing 31, as shown, secured to the shaft 34, being attached to cause a rotation of that shaft by the water pressure entering the housing from the pipe 16 and leaving the housing by the pipe 18 as shown in FIG. 4, in conventional manner. The conventional brush 17 has bristles 51 extending from its circular head 37. An outer flexible removable shield 50 is provided around the exterior of the brush head 37. Suitable connection strips 52 are provided to hold the flexible hoses 16 and 18 together as a unit adjacent the water powered brush 17 as illustrated, for convenience of the operator in using the brush 17, by manually grasping of 16-18.

From the foregoing construction, it will be seen that my water powered brush can be used whenever the water flows through the main water line 10-11 to the discharge head S whenever desired, by a manual operation of the handle 15 of the first or manual pivoted crank valve 13 of the first off-chute T water flow line 12. By an opening of that first pivot crank valve 13 counter-clockwise, as illustrated in FIG. 1, to position the valve as there illustrated, that will cause a flow of the water through the pipes 12 and 16 and the water flow will thus operate the rotary water powered turbine brush 17, and all of the water will then return by the return flow pipe 18 and 19, through the exit offset pipe 19 by the water flow raising the spring valve 20 and the water will be fully discharged out of the head S without any diminishing of the flow of the water from its original source. On the other hand, should the operator not need to use the brush but desire to use the water straight out the discharge end S, then he will turn the manually operable pivot door valve crank 13-15 to cause that door 13 to pivot clockwise on its pivot 14, to position the door 13 to fully close the offset T pipe 12 as shown in FIG. 3, and thus the water will fully bypass that closed door 13 and will not enter the pipe 12-16 and will not operate the brush, but the water will flow completely out the head discharge S. It is to be noted in the latter condition of a closing of the pivoted valve 13 just explained and the passing of the water straight through 11, that the spring actuated valve 20, as heretofore explained, is fully closed by its spring, as illustrated in FIG. 3, due to the action of that spring tension and further due to its design and the water flow thereover by the water pressure assisting in that closing, so that there is no water then entering into the water powered brush through either of the offset pipes 16 and 18.

Thus, applicant has provided the method of providing in a water pressure flow line a water powered brush by the steps of taking the water pressure by an offstep flexible line from the main line to operate the brush and then returning the water to the main line, and having the offset line and its brush adapted for use adjacent to and with a water outlet from the main line. Further, with the brush being adapted for operational use only when desired, but not required to be used if not desired or needed on main line water flow.

Thus, while I have illustrated and explained a preferred embodiment of my invention with relation to a shower bath head, it is to be distinctly understood that many other uses could be made thereof within the spirit, teaching and intent of my invention. For example: My invention could be adapted for use as a dental brush appliance device, where there was a water main stream outlet, and where leading as an offset before that outlet there was a flexible water powered brush in a flexible offset line extension connection therefrom, adapted for use therewith as one combined dental element. In the cleaning brush industry, such as for household use or in the automobile washing industry, there could be my water powered offset flexible conduit remote from the outlet, having my water powered brush in the offset for use with the main stream but without taking water therefrom.

The use of my novel water powered brush in the flexible takeoff off-chute line of the main water line is operated according to the method consisting of the following steps: (a) Taking water power by a flexible U-shaped hose off-chute line from the main water power line for the purpose of operating the turbine of a rotary water brush and then returning all of the water from the turbine thereby to the main water power line; and (b) Directing all of the water in the main line by a continuation of the main water line to its outlet discharge point.

Having thus explained, illustrated and described my invention, it is to be understood that the teaching, spirit, intent, and scope thereof is to be limited only by the hereunto appended claims.
