. ll This invention relates to a washing machine and more particularly to a washing machine for hollow or tubulartmembers such as water glasses.

An object of the invention is to provide a rotatable brush, driven by a fluid pressure, which is automatically controlled by the application of the article to be washed :on "the brush.

Another object of the .invention is to provide -aplurality of adjacent brushes,, rotatable in opposite directions, for cleaning the external and internal surfaces of an article such as a water glass.

.A further object of the invention is to provide a mot-or, `driven by a cleaningfluid under pressure, for rotatably driving a plurality of brushes and to control the flow of fluid through the motor, by a valve means operable by engagement of the article to be cleaned on one of the brushes.

Other objects and advantages of the invention will more fully appear from the following description taken in connection with the accompanying drawings in which- Fig. 1 is a sectional View of my improved device showing an embodiment of my invention; and

Fig. 2 is a sectional view taken on line 2-2 of Fig. 1 on enlarged scale.

Referring to the drawings I have shown a motor housing i having a rotor chamber i2. The chamber i2 is elliptical and receives a rotor i4 having a diameter substantially square to the dimension of the minor axis of the elliptical chamber !2. A cover plate IB is provided to close the open side of the chamber |2 and to position the rotor l4 in the chamber [2. The opposite faces of the rotor are in sliding engagement with a raised boss l8 on the bottom Wall of the chamber i2 and an inwardly projecting boss 20 on the cover IB. The

bosses

18 and 20 are elliptical as shown by dotted lines in Fig. 2 and the major aXes thereof are of less dimension than the diameter of the rotor l4. There is provided between the wall of the chamber !2 and the bosses [8 and 20 an elliptical track or groove which receives a plurality of blades 22. The blades 22 are received in radially extending slots 24 which are spaced circumferentially in the rotor l l.

A tubular member 25 is journaled in the cover !6 and the bottom of the housing and is fixed to the rotor i4 so that rotation of the rotor l4 causes rotation of the tubular member 28. The outer end of the tubular member 26 detachably receives a stem 28 of a brush 30. The stem 28 is provided with a longitudinal passage 32 having a valve seat 34 at its lower end. A valve rod 36 is guided .in the passage 22 and ;projects ou'twardly above the ?brush 30. .A spring BBabutting \an .apertured .shoulder, '4.0 .in the ,.passage 3'2 and 'the outer end of 'the rod, .urges the rod 36 ou'twarly normally closes the passage 32 from the tube '2B by a valve '42 on therod'iifi 'Seating against the valve seat '34( 4 Below 'the valve '42, .and ;carried by 'the rod 30, asleeve valve 44inormally closing 'lateral open- 'ings '46 'in the tube 2.5. The sleeve valve 44 'is provided with an opening 48 [for the paissage 'of the cleaning fluid therethrough.

'Cleaning fluid 'under ,pressure is admitted to 'the motor through an inlet pipe 50 and '

branched passages

52 and 54. The fluid pressure at 'opposite sides of the rotor l4 causes rotation thereof in a direction indicated by the arrows in Fig. 2. Exhaust fluid is received in outlet passages 56 Which are connected to the bottom of the tube 26 by passages 58.

When the parts are in the position as shown on the drawing the fluid passage 46 is closed thereby preventing a flow of fluid through the pump and consequently the rotor i4 is Stationary. When the valves 42 and 44 are opened such as by pressing the rod 36 inwardly, the discharge passage 46 is opened permitting the fluid to flow through the system and rotate the brush 30 driven by the rotor l4 and tube 26. Ordinarily the rod 36 is operated by the application of a water glass over the brush 30, the bottom of the glass engaging the outer end of the rod 36 and a slight pressure downwardly permits the fluid to discharge into the housing 60. A portion of the fluid is conducted through the passage 32 and discharged at the top of the brush 30, inside the glass draining over the brush 30 into the housing B0.

The housing 60 is detachably secured to the motor housing [0 by Screws 62 with a gasket 64 between the housing IO and the housing 60. An overflow pipe 65 has been provided for discharging the fluid from the housing 00 and is of a 4 predetermined height to maintain a constant fluid level within the housing 60.

The tube 26 carries a gear 68 which meshes with

gears

10 and 12 at opposite sides of the gear 68;., The gears '10 and '12 are drivingly connected brushes 14 and lG respectively. Rotation oi\ he brushes are in opposite direction to the direction of rotation of the brush 30. The brushes 14 and 1B clean the outer periphery of the water glass when the latter is placed over the brush 30. The brushes 14 and 15 are journaled in an overhanging projection 18 of the cover plate i6 and a removable plate 80 which is secured to the projection 18 by screws 82. A spacer 84 positions the removable plate 80.

If it is desired to add a solvent or soap solution to the cleaning fluid, a container 86 may be seits scope other than by the terms of theappended I claims.

I claim: 1. A washing device comprising a fluid motor 2. A washing device comprising a fluid motor housing having inlet and outlet passages, a tubular member journaled in said motor housing, a rotor mounted in said housing and carried by said tubular member, said tubular member'projecting outwardly beyond said housing, a gear mounted on said tubular member external of said housin a pair of gears rotatably mounted on said housing and in driving engagement with said first named gear, the outer end of said tubular member having radially extending openings' through its side wall,

- a valve for controlling the openings in said tubuhaving inlet and outlet passages, a tubular member journaled in said motor, said motor having a a rotor carried by said tubular member, said motor outlet passage communicating with one end of said tubular member at one side of said rotor, said tubular member having an outlet passage at the opposite side of said rotor, a rotatable brush carried by said tubular member, a valve for the outlet passage in said tubular member, said brush having an axially extending passage therethrough, a valve for said axially extending passage, a rod extending through said axially ex-` tending passage projecting beyond said brush and carrying said valves, and rotatable brushes adjacent said first named brush and rotatably driven by said rotor.

lar member, a second tubular member forming an extension of said first tubular member and communicating therewith, a valve for controlling the communication between said tubular members,

'said valves being connected togethenan axially extending rod projecting through the outer end of said second tubular member for moving said valves, and brushes rotatably driven by said gears.
