Abstract
Abstract A quick-change brush mounting for use in a printed circuit board scrubber or the like. The shaft of a cylindrical brush is journaled at one end to a bearing cartridge having a flanged, cylindrical end which seats in the circular opening of a plate. A retainer extending over the flanged edge maintains the bearing cartridge attached to the plate. By rotating the cartridge until a notch in the flange is aligned with the retainer, the cartridge may be detached and the brush withdrawn through the opening in the plate. To facilitate vertical adjustment of the brush, the cartridge plates may be slidingly mounted to side panels of the scrubber and provided with micrometer screws for moving the plates and hence for adjusting the spacing between the brush and the circuit board being scrubbed. An ammeter, associated with the brush drive motor, indicates the amount of loading on the brush.

A scrubber assembly comprising: a housing having first and second spaced parallel side panels, a generally rectangular opening extending through each of said panels, a substantially cylindrical scrubber brush extending on a shaft between said panels, first and second plates each having slotted edges and being disposed respectively within said rectangular openings for longitudinal movement with respect thereto, each plate having a cylindrical opening therethrough, first and second bearing cartridges each having a cylindrical end concentric with the bearings thereof, said ends seating within said circular openings, one end of said shaft being journaled to said first bearing cartridge, the other end of said shaft being detachably connected to a spindle journaled to said second bearing cartridge, and means for selectively retaining or permitting removal of said first bearing cartridge from said first plate, removal of said first cartridge facilitating withdrawal of said brush through said circular opening in said first plate.
Claim 7
Dependent Claim
152 words
A scrubber assembly comprising: a housing having first and second spaced parallel side panels, a generally rectangular opening extending through each of said panels, a substantially cylindrical scrubber brush extending on a shaft between said panels, first and second plates each having slotted edges and being disposed respectively within said rectangular openings for longitudinal movement with respect thereto, each plate having a cylindrical opening therethrough, first and second bearing cartridges each having a cylindrical end concentric with the bearings thereof, said ends seating within said circular openings, one end of said shaft being journaled to said first bearing cartridge, the other end of said shaft being detachably connected to a spindle journaled to said second bearing cartridge, and means for selectively retaining or permitting removal of said first bearing cartridge from said first plate, removal of said first cartridge facilitating withdrawal of said brush through said circular opening in said first plate.
Claim 8
Dependent Claim
36 words
A scrubber assembly as defined in claim 5 further comprising micrometer adjustment means cooperatively attached to said plates and said side panels for simultaneously moving said cartridges and hence said brush vertically of said side panels.
Claim 9
Dependent Claim
102 words
A scrubber assembly as defined in claim 6 wherein said micrometer adjustment means comprises: first and seCond brackets attached respectively to said first and second plates, first and second supports attached respectively to said first and second side panels in vertically spaced relationship to said brackets, a first micrometer screw threadingly connected between said first bracket and said first support, and a second micrometer screw threadingly connected between said second bracket and said second support, and chain interconnection means for causing said first and second screws to rotate in unison, rotation of said screws thereby causing simultaneous vertical displacement of said plates.
