DORSEY MALCOM ECKLEBERRY, OF LOCKWOOD, SASKATCHEWAN, CANADA.

DISK HARROW.

Specification of Letters Patent.

Patented Mar. 11, 1919.

Application filed February 21, 1918. Serial No. 218,526.

To all whom it may concern:

Be it known that I, DORSEY MALooM ECKLEBERRY, of the village of Lockwood, in the Province of Saskatchewan, Canada, have invented certain new and useful Improvements in Disk Harrows, of which the followin is the specification.

y invention relates to improvements in disk harrows and the object of the invention is to so construct a disk harrow that the weight of the driver is utilized to increase the draw upon the disks when in gear and thereby increase their cutting qualities and it consists essentially of the followin arrangement and construction of parts 8.8%1816- inafter more particularly explained.

Figure 1, is a perspective view of my disk harrow.

Fig. 2 is a side elevation showing the operative position by full lines and the inoperative position by dotted lines.

In the drawings like letters of reference indicate corresponding parts in the various figures.

1 indicates the main beam. 2 indicates a cross beam secured to the main beam intermediately of its length and connected thereto by inclined ortions 3 and 1. 5 indicates a supplementa cross beam, which is secured to the main beam 1 at one end thereof, the

ends of the cross beam 5 being connected by brackets 6 and 7 to the ends of the cross beam 2. 8 and 9 indicate pulley brackets secured to the outer edge of the cross beam 5 and provided with pulleys 10 and 11, 12

indicates a chain extending around'the pulley 10, and 13 indicates a chain extending around the pulley 11.

11 indicates a rod extending parallel to the cross beam 5 and adjacent to the outer edge thereof and to the ends of which the inner ends of the chains 12 and 13 are secured. The outer ends of the chains 12 and 13 are secured to the whiffletrees forming the draft gear of the cultivator.

15 indicates journal brackets. To one of the brackets 15 of each gang of disks l6 and 17 are bolted the outer ends of the cross beam 2. The brackets 15 are also provided with eyes 15* into which are hooked braces 1 which are connected at their opposite end' to the main beam 1. To the opposite end of the main beam 1 is secured the seat 18 mounted upon a suitable bracket 19, which is secured in position by a bolt 20 passing through one of a series of orifices 21 formed in the beam 1. Y

22 indicates a bearing bracket depending from the beam 1 beneath the seat 18 and-in which is journaled a bearing wheel 23. 24 indicates a foot rest, which is adjustably secured by a bolt 25 extending through one of the series orifices 21. 26 indicates a slot in the main beam. through which a controlling lever 27 which is usually employed for throwing the disks 16 and 17 in and out of angled position, passes.

It will be seen that when a team of horses is connected by the usual draft gear to the chains 12 and 13 that a downward pull will be exerted upon the corresponding end of the main beam 1, which is counteracted by the weight of the driver sitting on the seat 18 and thereby tending to force the cutting disks 16 and 17 farther into the earth, thereby producing a deeper cut and a more comp ete turn-over of the sOil.

The seat 18 and foot rest 2 1 may be adjusted longitudinally of the main beam 1 so as to suit the weight of the driver. When the machine is not in use or not in gear there will, of course, be no draft upon the disks 16 and 17 and the end of the main beam carrying the seat 18 will be supported upon the ground by the wheel 23 or in the position indicated by dotted lines in Fig. 2.

What I claim as my invention is In a disk harrow, a main beam, a draft connecting means carried by one end of the main beam, a cross beam also carried by the main beam adjacent to the draft connecting means and dividing such main beam into a long and short arm, gangs of disks located beneath the cross beam and on which the cross beam is mounted, and a seat carried on the extreme end of the long arm of the main beam remote from the disks whereby a downward draw is given to the disks by the weight of the occupant of the seat as the disks engage the soil.
