Abstract
The present invention is a flail of a size and solidity making it capable of cutting and shredding bushes and small trees such as are encountered on transmission line right-of-ways and other locations where it is necessary to periodically control the growth of the vegetation.
This bush-flail can also be used for clearing land by shredding the bushes and debris left after the merchantable wood has been taken out. The said flail consists of a generally horizontal rotating shaft with a plurality of chains attached to said shaft and a knife attached at the outward extremity of each such chain. The entire flail is supported by a frame adapted to be mounted on the articulated arm or boom of a crane-type carrier.
The said flail is equiped with a guard that prevents the debris from flying from the immediate proximity of the bushes and trees being cut.

Description
DISCLOSURE~
This invention consists of a rotating flail adapted to be mounted on the articulated arm or boom of a crane-type carrier such as an excavator and provides a machine capable of clearing the vegetation from a wide swath of ground by swinging such arm or boom to which such flail is attached from side to side while the entire machine moves forward. The flail consists of: a) a shaft, b) a drum mounted on said shaft and capable of rotating around said shaft, c) a plurality of chains attached to said drum, d) a heavy knife attached at the outward extremity of each said chain, e) an hydraulic motor capable of rotating said drum at a sufficient speed to enable the said chains and knives to efficiently cut and shred brush and small trees, said hydraulic motor being connected to a source of circulating hydraulic fluid, f) a frame adapted to mount the said bush-flail to the end of the articulated arm of a carrier An object of the invention is to provide an efficient machine that will not only cut but also shred the bushes and small trees over a wide area with one pass of the machine. A further object is to have a machine that can withstand without damage encounters with stones and large stumps and other obstructions that are often hidden among the bushes being cut. A further object is to provide a machine that can clear large areas, four hectares (l0 acres) or more per hour.
Some bush-cutting devices mounted on crane type vehicles are in existence. They are generally rotary mowers with cutting knives rotating in an horizontal plane around a vertical axle or shaft as in the bushwood chopper invented by Armand G.
Plante, number 2028676 or circular saws as in 2066291. These machines are often severely damaged by encountering obstacles such as rocks and large stumps that are hidden by the surrounding brush.
They are also generally inefficient, having to cut and shred one bush at a time. The hydraulic bush-flail, turning in a vertical plane around a generally horizontal axle or shaft, can cut and shred brush over and around such obstacles with ease thanks to its flailing chains equipped with heavy knives. Furthermore, it is a more efficient machine that cuts and shreds bushes and small trees encountered as it sweeps from one side of the right-of-way to the other. It does the job rapidly and neatly leaving the ground in an esthetic condition.

Claims (11)
1) An hydraulic bush-flail capable of cutting bushes and small trees, said bush-flail capable of being mounted on the articulated arm of a crane-type carrier. Said brush-flail consisting of:
a) a generally horizontal axle or shaft, b) a drum mounted on and rotating around the said shaft or axle, c) a plurality of chains mounted on the said drum so that when said drum rotates, said chains flail away in a generally perpendicular direction in relation to the axis of said drum, d) a plurality of heavy knives, one of said knives to be attached to the outward extremity of each said chain, e) an hydraulic motor mounted on said shaft and giving movement of rotation to said drum, and f) a frame supporting the extremities of the said shaft and adapted to be suspended to the outward extremity of the articulated arm of a crane-type machine.
a) a generally horizontal axle or shaft, b) a drum mounted on and rotating around the said shaft or axle, c) a plurality of chains mounted on the said drum so that when said drum rotates, said chains flail away in a generally perpendicular direction in relation to the axis of said drum, d) a plurality of heavy knives, one of said knives to be attached to the outward extremity of each said chain, e) an hydraulic motor mounted on said shaft and giving movement of rotation to said drum, and f) a frame supporting the extremities of the said shaft and adapted to be suspended to the outward extremity of the articulated arm of a crane-type machine.
2) An hydraulic bush-flail as described in claim 1 with the said drum being longer than the said axle, the part extending past the extremity of the said axle being hollow and leaving a cavity in which the hydraulic motor is situated.
3) An hydraulic bush-flail as described in claim 2 equipped with a strong semi-circular guard and enclosing the said brush-flail to a point at the front on a level with the said axle and at the back to a level with the lower extremities of the said chains and knives. The rear edge of said guard to be equipped with a double row of guard chains to stop any debris from escaping underneath the solid guard.
4) An hydraulic bush-flail as described in claim 3 where the hydraulic motor is connected to the hydraulic pump of a crane-type carrier.
5) An hydraulic bush-flail as described in claim 3 where the hydraulic motor is connected to an auxilliary pump activated by an auxilliary diesel motor mounted on the crane-type carrier vehicle.
6) An hydraulic bush-flail as described in claim 3 with an hydraulic cylinder mounted between the said frame of the said bush-flail and the articulated arm of the crane-type carrier to permit tilting the said bush-flail away from or towards the said carrier in order to position the bush-flail to conform to the slope of the surface of the ground where the bushes and small trees are being cut.
7) An hydraulic bush-flail as described in claim 6 equipped with an hydraulic adaptor where the said frame connects with the said articulated arm to permit the entire bush-flail to rotate on the horizontal plane 180 degrees in order to face in the right direction on the backswing of the said articulated arm.
8) An hydraulic bush-flail as described in claim 7 with an hydraulic valve to cause the automatic rotation of the said 180 degrees when the operator commands the articulated arm to reverse its direction.
9) A plurality of the hydraulic bush-flails as described in claim 3, each said bush-flail mounted on an articulated arm, the plurality of the said articulated arms being mounted on the same carrier permitting the said bush-flails to engage with the bushes and small trees to be cut by the forward movement of the carrier alone without having to swing the articulated arms back and forth.
10) An hydraulic bush-flail similar to the bush-flail described in claim 3 but with the hydraulic motor mounted on the frame and imparting a movement of rotation to the shaft, such shaft turning in conjunction with the drum.
11) An hydraulic bush-flail as described in claim 10 with the flailing chains attached directly to the shaft, thus eliminating the need for a drum.
