1. A sweeping apparatus for releasable engagement with a blade of a blade-carrying machine, the blade being arcuate in cross-section and having a top edge, a bottom edge, a left end portion, a right end portion, and a front face, the sweeping apparatus comprising:
a. a height and depth adjustable mounting assembly, comprising;
i. a first vertical support and a second vertical support connected to one another by at least one cross brace, each said first vertical support and said second vertical support having a top portion;
i. a first vertical extension member slidably and adjustably mounted to said top portion of said first vertical support, a second vertical extension member slidably and adjustably mounted to said top portion of said second vertical support, said first vertical extension member including a first forward canted arm, said second vertical extension member including a second forward canted arm, said first forward canted arm terminating in a first rearward canted arm extending perpendicular to said first forward canted arm, said second forward canted arm terminating in a second rearward canted arm extending perpendicular to said second forward canted arm; and
i. a first L-shaped extension bracket slidably and adjustably mounted to said first rearward canted arm to form a first U-shaped channel into which the top edge of the blade is inserted when mounting said sweeping apparatus to the blade, and a second L-shaped extension bracket slidably and adjustably mounted to said second rearward canted arm to form a second U-shaped channel into which the top edge of the blade is inserted when mounting said sweeping apparatus to the blade;
b. a carrier frame fixedly connected to said mounting assembly;
c. a sweeper brush assembly mounted to said carrier frame; said sweeper brush assembly including;
i. one of a sweeper shaft or drum rotatable about a longitudinal axis substantially parallel with the ground; and
ii. a cylindrical brush head comprising a brush hub mounted to said sweeper shaft or said drum for rotation therewith, said brush hub having a plurality of bristles, and
d. a sweeper motor mounted to said carrier frame and having a crankshaft coupled to said sweeper shaft to cause rotation of said sweeper shaft when said motor is energized;
whereby mounting of said sweeping apparatus across the front face of selectively either the left end portion or right end portion of the blade is accomplished by tilting the top edge of the blade forward, driving the blade-carrying machine forward until the top edge of the blade is inserted into said mounting assembly, tilting the top edge of the blade rearward and simultaneously lifting the blade vertically until the bottom of said mounting assembly comes into abutting contact with the bottom edge of the blade; and
whereby, the depth of each said U-shaped channel is adjustable to accommodate blades of varying thickness by sliding said first and said second extension brackets proximally or distally relative to the rearward canted arms from which they depend.
