To all whom it may concern:
Be it known that I, R. D. CARY, of the city I"' are arranged in the same manner in re

The nature of my invention consists in com~ their fulcrum-pins e. The brooms in their
bining and arranging with a cart or wagon forward movement pass from a position at '
one or more brooms or brushes and scrapers right angles, or nearly so, with the wagon to

street by the upper edges near the rear end
