"9 Claims. -'-(Cl. 15128) .This .invention relates :to portable"v fountain-type brushes havinghandles which.are.- adaptedt to,be..connectecl..to a

source of liquid supply, and more particularly to...a..brush ..of.this;type. in .whichthe .surface .engaging. portion :thereof v.can be. veryeasily .maintained. ,insa position.approxi- ..mately normal to.the.surface being washed.

Brushes. having handles. which maybe connected ,to a

..used.today -to wash. walls, vehicles, and .the. like; however, such-implements have .not. been entirelvsatisfactory inasmuch as washers have..experienced.cQnSiderabIeIdifii- .culty .in.maintaining thebru'shhead vimpositions in which '..the. bristlesaresubstantially normal .to the surface.

Frequently,,when surfaces. approximately on alevelwith, or. below the head of a washer are being .scrubbed ortwhen the. surface. is curvilinear or irregular, .the..washer...will

t. mar or scratch the surface. being cleansedby inadvertently rubbing a. portion of the. brush device, other ,than the bristles. against .the surface being washed; or. the. trim.-

thereof.

.Oneofitheprime objectsof the instant invention is to design a brush which can .beremotely. adjusted; without 'shiftingthe. implement in the. handset .the user; by..sirnply turning the valve. controlling the volumeaofa,liquid..supplied which is ..located..on...the.elongated .handle,..of,,.the

brush.

. on the angular position of the brush relative.to,th

A spring ;36,.n0.rmally holds the. plunger 3 sure, ofthe incoming .water or. other liquid .forces it gut- .wardly. into: one of {the notches.

In" practice, the operator may rest the brush B against the surface to be washed and thence pivot the handle movement relative thereto,

23 about the pin 18 until it is at the desired-angle relative to the brush. If the lever 27 is now turned to positioni shown in Fig. 3, the pressure of the liquid forces the; plunger 34 forwardly into the particular notch 35 whichn is in alignment therewith. The liquid flows through the: opening 29, tube 28 flexible tubing 30 and tube 31'. into the nozzle 32 and is sprayed, with considerable force, through the openings 33 onto the front bristles of the brush. Since the surface being washed is usually avertical or vertically inclined surface, the liquid being sprayed must traverse the entire width of the brush and wilt used with a maximum efficiency. When the washing operation has progressed to a point where the relative angularity of the brush and handle should be changed, it: is only necessary to turn off the liquid momentarily at the lever 27 which permits the spring 36 to retract the plunger 34 from the head 13d. The position of the handle 23 may then be adjusted in the above described manner.

While I have shown the device as particularly useful to clamp a brush, I contemplate that a wiper blade, mop, or other surface-engaging member or applicator'could also be employed. It is to be understood that the description and drawings are in all cases to be interpreted as illustrative of the invention rather than as limiting the scope thereof, and it will be apparent that various equivalent changes may be made in the various elements which comprise the invention, without departing from the spirit thereof or the scope of the appended claims.

What I claim is:

1. In a washing implement, a handle, a surface engag ing head therefor mounted thereon for generally pivotal means for supplying liquid to said head, and means associated with said handle and actuated by the pressure of the liquid feeding to said head for holding the head in a given position of relative adjustment to the handle.

2. In a washing implement, an elongated handle, a: surface engaging head therefor mounted for generall} pivotal movement relative thereto, means associated with the handle for feeding liquid, under pressure, to one end thereof and feeding it thence to said head, and pressure actuated means movable under pressure of the liquid into engagement with said head to hold the same in a given position of adjustment relative to the handle when pressure is applied to said means.

3. In a washing implement, an elongated handle provided with a liquid passage therein, a surface engaging head pivotally mounted on the outer end of said handle,v a line connecting said passage and head to transmit liquid from said handle to said head, and means at the pivoted handle end of said passage movable under the pressure of said liquid into engagement with said head to holdv the same in a position of angular adjustment relative t the handle.
