FRAME-ADJUSTING MECHANISM.

Specification of Letters Patent.

Patented Aug. 12,1913.

Application led .Tune 4, 1912. Serial No. 701,593.

To all whom, may concern.'

Be it known that I, HERMAN 1V. HITZE- MANN, a citizen of the United States, residing at Roselle, in the county of Dupage and State of Illinois, have invented a certain new and useful Frame-Adjusting Mechanism, of which the following is a specification.

'My invention relates to improvements in potato diggers, in which laterally revolving radial arms, secured to a disk, operate in conjunction with a plowshare; and the object is to furnish a framework, and wheelsA and axles to carry the same, for the mounting and operation of the mechanism described in my divisional application No. 731220 filed November 13, 1912.

Figure 1 is a plan view of my invention, showing it as ready to have a team hitched thereto and operate it; Fig. 2 is a side elevation of the same.

Like numerals refer to like out the several views.

Referring to the drawings: is a double bar connect-ing the front and rear axles of the digger; 11-11 are brackets securing the bar on the rear axle. The axle passes through these pivot-wise, and is rigidly secured at its ends to the rear wheels.

12 is a vertical shaft, secured at its lower end to the forward axle; 13 is a sleeve, bolted to the front end of the double bars; 14 is a bracket, bolted upon the upper, enlarged part of the shaft, 12, and bearing the segment of a gear or quadrant; 15 denotes the lower end of the lever 17 extending in front of the shaft.; 1G is a rod, pivoted on the lever, 17 and on the lug, 15 1,/2, secured on the front end of the double bars; 17 is a lever, pivoted on the bracket 11, at a point indicated. rlhis lever extends in front of the shaft, 12, and is pivoted to the rod, 16, as stated above.

1S is a rod which is pivoted to the lever 17. The rod 1S is also pivoted to the plug 20 1/2.

18 1/2 is a spiral spring of the usual common form, and it is secured about the plug parts through- 2O 1/2. This plug` is fitted to engage with the cogs of the quadrant which is a part of the bracket 111.

21-21 are bars, bolted to the bars, 10, and to the plowshare, 22.

The front end of the lug, 15 1/2, is slotted vertically to receive the clevis, 23, to which a double-tree may be attached.

The top of the shaft, 12, bears the casting, 24, rigidly secured thereon. To this a pole is attached. The clevis, double-tree and pole are each of well known, common construction, designed for hitching on a team to draw the digger.

A seat, l1, for the driver, is bolted centrally to the cross bar which is bolted to the double bars 10 near their rear end, and is so located that the driver has within his reach the handle of the lever, 17.

To Operate my invention a team is hitched to the digger by means of the double-tree and po-le above named, which are both well known, common construction; the driver, mounted on his seat, employs the handle, 17, with its spiral spring, 18 1/2, to depress the plowshare to the right level to bring its point below the potatoes in the hills.

'Vhat 1 claim as new and desire to secure by Letters Patent of the United States is In a frame adjusting mechanism, the combination of the double bars, 10, connecting the front and rear axles, the shaft, 12, bearing radial arm, 14, the sleeve, 13, inclosing said shaft, the lever, 17 pivoted on the arm, 14, rod, 16, pivoted at its upper end in the lower end of the lever, 17, extended, and at its lower end in the lug, 15 1/2, secured on the front end of the double bars, and the plowshare, 22, substantially as and for the purpose specified.

In Witness whereof I hereby subscribe my name and aiiix my seal to the foregoing specification, at Chicago, Illinois, this 17th day of May, A. D. 1912.

HERMAN W. HITZEMANN.
