LOREN GRANT JACKSON, OF WOODMAN, WISCONSIN, ASSIGNOR OF ONE- HALF TO OSCAR M. L OOMIS, OF SAME PLACE.

POTATO-DIGGER.

SPECIFICATION forming part of Letters Patent No. 330,898, dated November 24, 1885.

Application filed July 1, 1885. Serial No. 170,371.

To all whom it may concern:

Be it known that I, LOREN G. JACKSON, a citizen of the United States, residing at Woodman, in the county of Grant and State of WViscousin, have invented a new and useful Improvement in Potato-Diggers, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to an improvement in potatodiggers; and it consists in the peculiar construction and combination of devices that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a potato-digger embodying my invention, the near wheel being removed. Fig. 2 is a top plan view of the same. Fig. 3 is a detailed perspective view of the digger.

A represents the axle, to which is secured the rear divided end of the tongue 13, which forms the frame, a transverse beam, 0, being secured between the rear divided ends of the tongue, which extend a slight distance beyond the rear side of the axle, as shown. A transverse bar, D, is secured to the tongue at a suitable distance from and in front of the axle, said bar being secured on the under side of the tongue, and on the upper side thereof, in rear of the bar D, is a transverse beam, E. A spring-standard, F, is secured to the center of the axle, and carries the drivers seat G. Slotted standards H depend from the ends of the bar D, and similar standards, I, depend from the rear divided ends of the tongue, the standards H being braced, as shown.

K represents a hand-lever, that is journaled on one end of the beam E, and has an arm, K, bent at right angles, and L represents a similar hand-lever journaled on the rear end of the frame diagonally opposite the hand lever K, and having a bent arm, L.

The scoop or digger M is composed of the curved fingers m, which are secured at the proper distance from and parallel to each other on a transverse bar, m. To the outer 0f the fingers are bolted the curved beams 012?, which extend through the slotted standards H and I, and are secured together by trans- (No model.)

verse bars m, journaled in the braces W. This scoop or digger is suspended below the frame by straps m, which connect the bars in with the bent arms K and L of the handlevers. Transverse bolts or pinsm are passed through the forward extended ends of the beams m and bear against the front sides of the standards H, and sustain the draft of tlie digger. Rack-segments N are provided on the frame, and the hand-levers are provided with springactuated bolts 0, to engage with the racks and hold the levers at any desired position. Sup porting-wheels P are journaled on the ends of the axle in the usual manner. By means of the hand-levers the digger or scoop can be caused to run in the ground at any desired depth or to be raised out of the way when in transportation and not in operation. The transverse bars m form fulcrunrpoints for the beams of the digger. By means of the levers K L either the front or rear end of the digger may be raised or lowered, and thus in cline the digger to any desired angle. By this construction perfect adjustability is provided for the digger, and it is thereby rendered capable of being adjusted so as to run in the ground at any desired angle or at any desired depth. As the machine moves along, the digger uprootsthe potatoes, and as they move rearwardly over the digger they are cleared of adhering earth and roots and deposited on top of the ground.

A potato-digger thus constructed is exceedingly light, cheap, and simple, is thoroughly practical in operation, and is not likely to get out of order.

Having thus described my invention, I claim- 1. In combination with the frame and the levers, the digger or scoop composed of the 2. The combination of the frame having the,

levers K L and the depending slotted standards H and I with the scoop or digger having thecurved parallel fingers, and the side In testimony that I claim the foregoing as beams, m working in the slotted standards, my own I have hereto affixed my signature in the transverse bars m journaled in the beams, presence of two witnesses.

and the links W, connecting the said bars- LOREN GRANT JACKSON. 5 with the levers, whereby the scoop or digger Witnesses:

may be raised or lowered at either end, sub- J. MOLAUGHLIN,

stantially as described. HENRY R. FLORY.
