FRANK BUCHET AND ELMER A. MULLINIX, OF WALLA WALLA, WASHINGTON.

DISK HARROW WEEDER.

Specification of Letters Patent.

Patented Jan. '7, 1908.

To all. ulzom it 'may concern:

Be it known that we, F RANK BUCHET and ELMER A. MVLLINIX, citizens of the United States, residing at W alla Walla, in the county of Wallawalla and State of- Washington, have invented a new and useful Improvement in Disk Harrows or lfVeeders, of which the following is ya specili'catiorifl j This invention relates to liarrows or weeders of that class having a plurality of disks, and has forits object to provide an improved frame for supporting the disks, and provided with means 'for raising or lowering the frame to var v the depth of cut or to lift the disks from the ground. A further object is to provide novel and improved means for varying the angle of the disks with respect to the line of draft.

The implement is illustrated in the accompanying drawings, in which Figure l is a top plan view thereof. Fig. 2 is a side elevation. Figs. 3 and 4 are details of the disk hangers.

The frame of the machine is composed of front and rear bars A and B, and side bars C and D, joined together at the ends to form a rectangular frame. The bars are preferably angle irons with, the vertical flanges standing at the outer edge. The front and rear bars are connected by cross supports E, F and G and the tongue H is attached to the front bar A and to the front end of the cross bar F, by suitable braces and bolts. The seat K is supported on the middle cross bar F. The whole frame is thus cheaply and stoutly formed of angle and strap irons, bolted together. The disks R are carried in two gangs or rows, one under the front bar and the other under the rear bar of the frame. Each disk is supported by a hanger casting S which has at the top an arm s with a short end of which is pivotally connected the horizontal flange of the frame irons by a bolt T' and the long end of which is connected toA laterally sliding angle bars U by pivot bolts u, and by shifting these bars the disks are turned on the pivots T to vary the angle thereof with respect to the line of draft. The vertical flanges of the said bars C and D of the frame are slotted is indicated at c, and the ends of the bars U extend and Work through these slots, and vrest upon theh0ri zontal flanges of said side bars, the vertical flanges of the bars U being cut away at the ends, to permit the movement.

`The long ends of the arms s ot the disk nected by rods a to the shifting bars respec-v tively, and it is obvious that the angle of the disks may be varied as desired, by manipulation of the lever.

The frame and parts carried lthereby are' mounted upon cranked axles M and wheels- L, at opposite sides of the machine, each axle having its latch lever P and quadrant Q, the latter being bolted to the cross bars E and G and the axles nding bearings in said bars and in the vertical flanges of the side bars C and D. The depth of cut of the disks may be varied, or they may be lifted entirely from the ground, by proper operation of the levers. The simplicity, convenience and ease of operation are apparent, as well as the cheapness of construction, all the main parts being readily produced of stock or ordinary material, the only particular or special casting reuired being the disk hangers. The line of raft is not varied at any angle of the disks and the lateral pressure of one gang is counteracted by that ofthe other.

We claim An improvement in disk harrows, substantially as described consisting of a main frame having side bars provided with guide openings and having front and rear bars'in advance and in rear of their respective guide openings, slide bars' movable laterally in the main `frame and guided in the said guide openings, said slide bars being arranged one -in rear of the front bar and the other in ad- 'Vance' of the rear bar, a lever pivotally supported in connection with the main frame midway between the said slide bars and movable in a lateral direction between said slide bars, detent means for securing said leverl in operation of the` lever, disks below the front and rear bars, hanges'for said disks jour Operate to tilt the front and rear disks, all nal'ed vertically vin the frnt and rear bars substantially as and for the purpose set forth'. 10 and having for the front disks rearwardly .FRANK BUCHET rejecting crank arms, and for the rear disks ELMR A MULLNIX 5 orwardly projecting crank arms, the said front and rear crank arms being votally Witnesses: connected with their respective slide bars GEORGE W.
