Abstract
Abstract A hollow tubular handle is connected at one end to a pressurized water supply and carries a sprinkler head at its other end. A brush attached to the sprinkler head is formed with a hole through which water from sprinkler head passes without contact with the brush. A tubular member extends from the sprinkler head partially through the hole in the brush to prevent the bristles of the brush from being bent into the flow from the sprinkler head when the brush is pressed against a surface to be washed such as an automobile body.

Claim 1
Independent Claim
226 words
A brush assembly comprising, in combination: a hollow handle having an end portion which is threaded, said end portion comprising a sprinkler head formed with a nozzle having an outwardly extending flange; an annular plate connected to said nozzle and being formed with a hole therethrough which is concentric with and larger in diameter than said end portion, and being formed with an inwardly extending flange which is sealingly engaged with the flange of the nozzle; a sprinkler disc carried by said end portion; sealing means between said nozzle end portion and disc; a grouping of bristles extending from the plate axially away from the handle; a resilient diverter tube extending concentrically from said nozzle in alignment with the nozzle and located centrally witin the group of bristles, said tube being formed with a flange at an axially inner end thereof, the axial length of the tube being between 1/3 and 1/2 of the length of the bristles so as to thereby prevent the bristles from being bent inwardly toward the hole of the plate, whereby the bristles when pressed against a hard surface cannot bend inwardly to the point of closing off the hole; and, clamp means for sealingly clamping the flange of the tube to the annular plate and said nozzle, said clamp means including a nut formed with threads conjugate to said nozzle.
