- the handle comprises an upper fork and a lower fork 10].
- Each pair of legs or tines of the upper and lower fork members diverse from an intermediate yoke I02 which is connected to or formed integral with the lower fork.
- the upper fork is pivotally attached at a pivot I03 to the yoke 102 and the latching arrangement securing the upper fork in its extended position (FIG. 3) is best shown in FIGS. 8 and 9.
- the upper fork terminates in a pair of hand grips I04 integral with an intermediate piece I05.
- a shampoo dispensing control lever I06 and associated linkage is incorporated in one tine of the upper fork as seen in detail in FIG. 5.
- the lower fork is adapted to receive a shampoo tank 99 which is removably attached thereto as will be described in connection with FIGS. 6, 7 and 8.
- FIG. 5 which is a cross-sectional view taken on line 5, 5 of FIG. 4 illustrates the shampoo dispensing linkage interconnecting the control lever 106 and a valve actuating rod I20 of the shampoo tank 99.
- the lever 106 is shown in a stowed or retracted position in the figure and when it is elevated about pivot I07 by movement in the direction indicated by the arrows to the horizontal position, the inner end 108 of the lever bears against a shoulder I09 of the push rod IIO.
- the push rod III] is held in position within the recess of the fork 100 in any suitable manner.
- the other end of push rod 110 is bifurcated at its lower end.
- One branch "M of the bifurcated end of push rod I10 has a helical compression spring Ill concentrically surrounding it whereby the rod is urged upwardly so that the upper end of the push rod I10 engages a stop defined by the upper end of the tine recess as shown.
- the branch 110b of push rod 110 is positioned in a retracted position within the tine I00.
- the motion translator 112 is urged upwardly within the yoke by a compression spring 113, in which position the top of the actuator is just flush with the associated surface of the yoke.
- the translator I I2 is moved downwardly by the branch “0b of the rod "0 when the lever 106 is lifted.
- the translator end 112a of the translator 112 is therefore moved into engagement with the valve actuator rod I20 of the shampoo tank 99 and moves rod I20 downwardly against spring 115 which normally urges the rod I20 upwardly.
- the lower end of rod carries a valve 1200 (FIG. 6) attached to the rod in any suitable manner and a valve seat 990 is formed integral with the tank 99.
- the valve I201 is unseated when the lever I06 is lifted when in its extended position (FIG. 5) and the liquid in the tank flows into the mounting block I30 attached to the lower end of the tine I01.

- the tube 86 may deliver liquid into a channel formed integral with the splash plate.
- reference numeral 13a identifies an upstanding hollow conduit, integral with a splash plate and communicating with a channel (not shown) in the splash plate which conducts liquid to one of the brushes.
- the upper end of conduit 13a terminates in a suitable opening in the hood 5 as shown in FIG. I. As shown in FIG. I
- the tube 86 remains in position when the tank 99 is removed since the mounting block I30 remains connected with the tine of the fork IOI.
- the mounting block I30 consists of a resilient synthetic resin formed by moulding.
- the tine 10] of the lower fork is generally U-shaped and is dimensioned to receive the mounting block 130 as shown in FIG. 7.
- the mounting block is held on the tine by a finger I3I having a recess which receives the projection 118 of the tine MI.
- the block is free to move in a longitudinal direction relative to the tine I01 between an upper stop and a lower stop provided on the tine (not shown).
- a mounting block on the other tine of the lower fork is identical to mounting block 130 with the exception that no provision is required for passing shampoo liquid through it.
- FIG. 8 shows the upper end of the shampoo tank 99 held between the tines of the lower fork 101 by a pair of lugs 135.
- a handle 150 on the shampoo tank is pivoted at 151 and when the handle is lifted fromthe position shown in FIG. 8 in the direction indicated by the arrow, the surfaces 152 of the handle engage the lugs I35 forcing the bottle downwardly thereby moving the mounting blocks against the compression spring I36 (FIG. 6) concentrically surrounding the spring pilot I37 (FIG. 7).
- the lugs 155 on the handle cooperating with the lugs 135 are free to slip past the lugs 13S and the tank 99 is withdrawn from between the tines of the lower fork. Then the tank 99 is placed on the fork by placing the bottom of the tank on the mounting pads and pushing it into the fork I01 until the lugs 155 slip past lugs I35.
- each tine of the upper fork I has a configured ear 1000 which fit in an appropriate slot in the yoke I02.
