Rotary broom with gearbox drive
First Claim
1. A rotary broom that pivots angularly in relation to input power, said broom including a brush of bristles upon an axle, the axle turning upon framing under power from a power take off of a vehicle, comprising:
- a frame, generally open and rectangular, adapted to connect to a three point hitch from the vehicle, and adapted to admit a driveline from the power take off of the vehicle;
a double gear box having a bottom gear box and a top gear box locating above said bottom gear box, said double gear box connecting to said frame, said bottom gear box having an input shaft adapted to connect to the driveline from the power take off of the vehicle and an output shaft perpendicular to its input shaft and inserting into said top gear box, said top gear box receiving said output shaft of said bottom gear box and said top gear box rotating upon said output shaft of said bottom gear box;
a guide plate connecting to said top gear box outwardly from said frame, said guide plate having an arcuate slot therein;
a semi-circular pivot plate having a straight edge and an opposite arcuate edge, said straight edge of said pivot plate adapted to connect to the center of the framing of the brush, said pivot plate rotating about an axis perpendicular to the driveline from the power take off of the vehicle, said pivot plate pivotally connecting to said frame generally beneath said bottom gear box, said pivot plate slidably engaging said guide plate wherein said brush rotates through a predetermined angle;
a second driveline connecting to said top gear box and to the framing of said brush wherein said rotary broom transmits power from the driveline from the power take off of the vehicle through said gear box to said second driveline and to the axle of the brush; and
,said top gear box, said second driveline, and said guide plate being capable of disconnection from the remainder of said broom wherein said broom has an orientation of one of to the left or to the right of the driveline from the power take off of the vehicle.

Abstract
A rotary broom mounts upon a slotted plate that pivots upon a double gearbox. The broom has bristles upon an axle within a shield that receives power from a chain drive that receives its power from a driveline from a top gear box. The top gearbox orients in the direction of the chain driveline and delivers its power through an output shaft. The top gearbox joins to a slotted plate that turns in the same direction as the broom. The top gear box receives its power through an input shaft perpendicular to the output shaft. The top gearbox input shaft extends downwardly and becomes the output shaft of the bottom gearbox. The bottom gearbox has an input shaft that connects to a power take off. This rotary broom receives rotational power, rotates it 90° upwardly, then rotates it 90° downwardly and at an angle laterally to drive the broom.
