, scum. (01. 37- 144) The invention relates to graders ofthat type intended for heavy duty and sometimes known as bulldozers." Such machines are usually procrank-actuated mechanism to adjust the boom to the desired angle. At the forward end of the boom is a sheave L for a hoisting cable M vided with an endless chain or so called cater-- pillar tread, for advancing the same, and carry at the front end a heavy blade for cutting and shovgrader with means fox-quickly disengaging and removing such obstructions and to also adapt the machine for other-work. To this end the invention consists:

First, in providing the grader with a forwardly extending boom and hoist. which is operable by elevation of my improved provided atv its outer end'with a suitable hook N. The rear end portion ofthe cable is wound upon a drum 0 having-a hand-operated crank 0' and suitable ratchet or holding means 0'. mediate this drum and the sheave L there is mounted. preferably within the hollow boom, a hydraulic jack P, the plunger of which carries a sheave Q for engaging the cable M. The arrangement is such that when the plunger of the Jack is moved rearward. it will draw a loop in the cable M, thereby lifting the hook N to raise a load suspended thereby.

with the construction as described, the grader is operated in the usual manner, the boom G" being raised to a sumcient angle to be out of the way. If an obstruction is in the path of the blade D, the hook N on the cable M is lowered by unwinding the portion of the cable on the applied is of standard construction and forms I no part .of the present invention. Briefly described, it comprises a tractor A provided with a cab B for the operator and the controls, and

drum 0, and the hook is'then'suitably connected with the obstructlngmember. The slack in the I cable is taken up by winding up the drum 0, after which the hydraulic Jack P is operated to move rearward the sheave Q, drawing a loop in the cable, as indicated in dotted lines'-- in Fig. 1.

This will lift the obstructing member,- which can then be carried by the tractor to a suitable point for deposit. If the amount of movement eflected endless chain or caterpillar tread drivers C on opposite sides thereof. The blade D is carried prises the cylinder F, bell crank lever F, and link' l". The blade D is preferably centrally pivoted to the frame E and is provided at its opposite ends with adjustable links E through which the. angle of the blade may be changed as desired.

My improvement comprises a boom G having the bifurcated rear end portion G pivotally attached at H to the U-shaped frame E. The boom, preferably a hollow box member, extends forward over the blade D in the central plane of the machine and is supported at the desired angle and raised or lowered by a guy cable 1. One end of this is fixedly attached to one side of the frame E, passing forward therefrom and around a sheave J near the forward end of the boom and then rearward to the opposite side of the frame E where it is attached to a winding drum K. This drum may be operated by a suitable 55 out departing from the p r t of my invention.

by the hydraulic Jack P is not sufflcient to lift the obstructing member clear of the ground, the hydraulic cylinder F, connected withthe frame E, maybe operated to effect a further lifting.

My improvement also adapts the grader for the 7 it is obvious that it might be mounted on the blade itself. p

My improved construction greatly facilitates theoperation of the grader, for the boom is always in positiomready for instantaneous use. and

it is obvious that the structurebothofthe boom r and the hoisting apparatus, may be varied with- Interapparatus may also be quickly oper- I What I claim as my invention is:

1. In a grader, the combination with a tractor, a blade propelled thereby located forward thereof, and a frame on which said blade is mounted vertically adjustable in relation to said tractor, of a boom mounted on said frame and extending forward over said blade, 9. cable hoist depending from the forward end of said boom, and hy-' draulic-actuated means for operating said hoist.

2. In a grader, the combination with a tractor,

a blade propelled thereby located forward thereof. and a frame on which said blade is mounted provided with hydraulic operating mechanism for raising or lowering the same, of a boom having a 'hollow boom having its rear end mounted on said frame and extending forward over said blade, cable guy means for raising and holding said boom at a desired angle, a cable hoist depending from the forward end of said boom, and

a hydraulic jack mounted within said hollow boom for actuating said hoist.

4. In a grader, the combination with a tractor,

a blade propelled thereby located forward thereof, and a frame on which said blade is mounted provided with hydraulic operating mechanism for raising or lowering the same, of a boom having its rear end mounted on said frame and extending forward over said blade, means for raising and holding said boom at a desired angle, a cable hoist depending from the forward end of said boom passing around a sheave at said forward end, a winding drum mounted on the boom to which the opposite end of said cable is attached, a hydraulic jack mounted on the boom, and a sheave actuated by said Jack engaging said cable between its depending portion and said winding drum being adapted to draw a loop in said cable and to thereby raise its depending portion.
