Powder dispensing and cleaning apparatus
First Claim
1. A dispensing apparatus comprising:
- a hopper formation including forward, rearward, side and bottom wall portions wherein the lowermost section of the forward wall portion terminates in a generally horizontally extending edge formation and the bottom wall portion presents a like horizontally extending edge formation so as to define a discharge orifice formation between said edge formations;
means supporting said bottom wall portion for swinging movement downwardly to move said edge formations towards and away from one another;
means for imparting reciprocatory movement to said swingable bottom wall portion;
a rotary brush formation mounted for rotation in spaced relation below and rearward of said edge formations on an axis parallel to said edge formations; and
means for imparting rotation to said rotary brush formation while reciprocatory movement is imparted to said swingable bottom wall portion.

Abstract
Method and apparatus for controlling dispensing of "dry" powdered compositions particularly carpet cleaning compositions wherein the confined finely divided particles descend in a stream under gravity and have oscillatory movement imparted thereto next before discharge through an orifice leading therefrom so as to agitate, separate and propel the particles therethrough; and in the case of carpet cleaning operations depositing the finely divided discharged particles onto the surface of the fibres in a substantially uniform pattern thereover followed by working same into the fibres through the application thereto of a rotary brush or beater and thereafter recovering the residues by a suitable suction or vacuum unit utilizing a rotary brush or beater and an associated two stage cyclone separator.

6. An apparatus for controlling the dispensing of a particulate composition onto an underlying surface comprising:
-
a receptacle portion having front, side and rear wall formations upstanding from a bottom wall formation including a displaceable pathway portion partially defining a discharge orifice formation for the passage of the particulate composition therethrough; means supporting said receptacle portion for travel over the underlying surface and so present said discharge orifice formation to extend across the path of travel; and means carried by said support means for imparting reciprocatory movement to said displaceable pathway portion.

7. A carpet cleaning apparatus comprising:
-
a hopper formation for the dispensing a particulate cleaning composition onto an underlying surface; a rotary brush for working such composition on the underlying surface; said hopper formation including a receptacle portion having front, side and rear wall formations upstanding from a bottom wall formation including a displaceable pathway portion partially defining a discharge orifice formation for the passage of the particulate composition therethrough; means supporting said receptacle portion for travel over the underlying surface to be treated and so present said discharge orifice formation to extend across the path of travel; said rotary brush being mounted for rotation within said support means so as to contact the underlying surface and extend across the path of travel; and means carried by said support means for imparting reciprocatory movement to said displaceable pathway portion and for rotating said rotary brush.

8. A carpet cleaning apparatus comprising:
-
a hopper formation for dispensing of a particulate cleaning composition onto an underlying surface; a rotary brush for working such composition into the fibres of the surface; a rotary suction fan, a collection means for collecting residues of such composition and a nozzle communicating with the rotary suction fan and the associated collection means for recovering and collecting residues of such composition from the surface; said hopper formation including a receptacle portion having front, side and rear wall formations upstanding from a bottom wall formation including a displaceable pathway portion partially defining a discharge orifice formation for the passage of the particulate composition therethrough; means supporting said receptacle portion for travel over the underlying surface and so present said discharge orifice formation to extend across the path of travel; said rotary brush being mounted for rotation within said support means so as to be presented to the underlying surface and extend across the path of travel; said nozzle mounted on said support means to embrace said rotary brush and communicate with said rotary suction fan and associated collection means through a conduit extending between said fan and collection means; and means carried by said support means for imparting reciprocatory movement to said displaceable pathway portion and for rotating said rotary brush and rotary suction fan. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A carpet cleaning apparatus comprising:
- a base and wheels for supporting the apparatus for travel, a swingable handle formation projecting upwardly from said base for directing said base along a path of travel, a rotary brush mounted for rotation within said base to extend transversely of the path of travel of said base and project therebelow, a hopper formation mounted upon said base for receiving a particulate cleaning composition to be dispensed, a receptacle portion having front, side and rear wall formations upstanding from a bottom wall formation, a displaceable pathway portion partially defining a discharge orifice formation for the passage of the particulate composition therethrough, the discharge orifice formation being responsive to the displacement of said pathway portion and being arranged so as to extend transversely of the path of travel of said base and deliver the dispensed particulate composition therebeyond, means carried by said base for imparting reciprocatory movement to said displaceable pathway portion and for rotating said rotary brush, and switch means for controlling the imparting of said reciprocatory movement to said displaceable pathway portion and the imparting of rotation to said rotary brush.
