A further object of this invention is the provision of a mounting for the cleaning elements, which will form an efficient means for the handlin'gof the device and alsopermits of said device to be readily and quickly applied to a hose.
A still further objectvof this invention is the provision of a brushl of the above'stated character which will be simple, durable and i eiicient, and which may bey manufactured and sold at a comparatively low cost.
With these and other objects in view as will become more apparent as the description proceeds, the invention consists y'in cero ment-s within the holder,

tles 4 constructedpfrom comparatively softY h air or 'material' and which project outwardly of the casing kfor the purpose of en- A rotatable cleaning element 5 is located within the casing and' also within'the head 3 of the stationary cleaning element 2-and .consistsof a head 6 of circular formation and has secured to one face a plurality of tufts of bristles 7 which are of a very soft nature. The head 6 is provided with a centrally arranged opening 8 and each face of the head surrounding said opening 8 is provided withbearing plates 9. The bearing plates 9 are secured to the head 6 by fasteners 10. A spindle 11 has formed upon one end ahead 12 provided with arms 13 that are secured to the top wall'of the casing 1 by fasteners 14 and said spindle extends downwardly through the opening 8 of the head 6. A nut and washer is positioned on the free end ofthe spindle for the purpose of retaining the head 6 thereon and to permit the cleaning lelements 5 to vhave free rotation within the casing and within the stationary cleaning element 2.
A band 15 is secured to the periphery of the head 6 and has ysecured thereto a plurality of radially' extending fins or'plates 16, the free `ends of which terminate in close proximity to the side of the casing 1. nozzle 17 is formed on the casing 1. and extends from the casing in an inclinedplane and hascomrnunication with the interior of said casing so that water injected into said nozzle from a hose 1S will strike against the' Specification of Letters Patent. f Patented Oct. 4, 1921.V l
and its outer end receives an ordinary nozzle on the endof the hose 18.
said nozzle and has its outer end cut away t0 the handle for the purpose of preventing said hose from coming in contact with the surface on which the brush 1s operating.
A protecting element 22 constructed from rubber or any other material suitable for the purpose is of a corresponding shape to the casing 1 and 'is placed over the casing and is provided with cut out portions 23 to receive the nozzle and the handle. The protecting element'22 is adaptedfto prevent the casing from coming in contact with the article on which the brush is operating thereby obviating any danger of the casing scratching or marring the surface of said article.
The water passing ,into the casing from the hose strikes againstthe fins rotating the cleaning element 5 withinV the stationary cleaning element 2 and the water saturates the bristles of the cleaning element 5 and passes onto the surface of the article being scrubbed or washed, thereby removing foreign' matter from the surface of the article thatl has been loosened by the rotation of the cleaning element 5. The bristles of the stationary cleaning element 2 confine the water and prevents the same from being thrown by centrifugal force over too large an area.
`IVhile I have lshownl and described the preferred embodiment of my invention, it will be understood that minor changes in vrconstruction, combination, and arrangement of parts may be made without departing from the spiritand scope of the invention as claimed.
I-Iaving thus described my invention what I claim is z- V A brush comprising a casing, a station? ary cleaning element carried by said casing,
a rotatable cleaning element carried by said j casing, a nozzle carried by said casing and arranged 'at the inclination to the casing, fins carried by the rotatable cleaning element, a
handle secured'to. the casing and inclining y toward the nozzle, a hose clamp `carried by said handle and adaptedtobel attachedto a hose for supporting the same inalinement
