SPECIFICA'JIIONVforming part of Letters PatentNo. 693,451, dated vlebruary 1.8, 1902.

Application ined october 21,1901. stanno. 79.4.61. (Nomads.)

To @ZZ whom, it may coi/accrul p Be it known that I, WILLIE H. C. SCHUBERT, a citizen of the United States,residin g at Britt, in the county of Hancock, State of Iowa, have invented certain new and useful Improvements in Plows; and I do hereby declare the following to be a full,clear, and exact descripa tion of the invention,such as will enable others skilled in the art to which it appertains to make and use the same. l

This invention relates to plows in general, and more particularly to the class of plows known as disk plows, the object of the in-` vention being to'provide a simple and efficient construction of this nature wherein the angle of the disk may be varied and reversed, as also the degree and direction of pitch thereof.

A further object of theinvention is to provide a construction'which will permit of ad-k justment of the parts easily and quickly without the operator leaving his seat, so lthat the parts may be shifted at the end of each row, other objects and advantages of the invention having reference to details of construction, which will be understood from the fol-4 i lowing description.

In the drawings forming a portion of this specification, and in which likenumerals of reference indicate similar parts in the several views, Figure 1 is a side elevation of the plow with the disk in a vertical plane, as when transporting the implement from place to place. Fig. 2 is a rear elevation of the plow with one side of the frame thereof lowered to give a corresponding pitch to the disk. Fig; 3 is a detail view of the disk with the mechanism for adjusting it rotatably to vary the width and direction ofthe furrow.

'Referring now Ato the drawings, there is shown a plow comprising a frame including an axle 10, having the straight end portions 11 and 12, forming spindles, on which are mounted the supporting-wheels 13 and 14, the portion between the spindles being curved upwardly to form the arch 15, Y

The wheels 13 and 14 are the front wheels of the implement, the rear Wheel-of the implement being a caster-wheel 16, the easter 17 of which is journaled at its upper end in a suitable bearing at the rear end of the plowbeam 18. At a point somewhat in advance of the middle of the plow-beam are pivotally connected the braces 19 and 2O through the medium of a collar 21, engaged in a circumferential groove formed in the beam,the outer or opposite enuds of the braces being connected to the sides of the arch 15. Connected also to the beam, but'rigidly, are the

arms

21 and 22, which diverge in the direction of the axle, beneath which their outer ends are passed.` the extremities of these outer ends having upwardl'y-c'lirected and spaced

fingers

23 and 24, between each pair of which is disposed one of the spindles of the axle, as shown. an angular' lever '25,` provided with a handle portion 26 for rocking it and havinga trigger 27, with which is connected the pawl 28 for engagement with the notched segment 29 for Vholding the lever at different points of its pivotal movement. The opposite end of the lever has a link 29' connected lheretowl1ich link4 Upon each side ofthe arch ispivoted in turn is connected, through the medium of the bail 30, with the upper ends of the fingers of the adjacent arm. If, then, one'of these levers 25 be raised and the other lowered, one arm will be raised and the other lowered and the plow-beam will be tilted laterally, While if both levers are similarly positioned the beam will be held level.

vThe disk of theplow is shown at 35 and is rotatably mounted upon the spindle 36 at the Vlower end of the shaft 37, the upper end of which is passed through a bearing 38 in the plow-beam in the rear of the 'point of connee tion of the

braces

19 and 20 therewith, and

.concentric with which shaft is arranged a notched segment 2l. A lever 22 is fixed to the upper protruding end of the shaft and carries a trigger 23', connected to the pawl 24s, upon the lever and arranged to engage the notched segment to hold the lever at different points of its adjustment.

By manipulatingv the lever the shaft may be rotated and the connected disk may be moved to reverse or vary its angles to the beam.

In practice when a furrow is to be made one of the levers 25 is raised andthe other' lowered, the disk having been adjusted to throw the furrow in the proper direction, and when the .endlof the furrow is reached the proper lever is oppersrated` to right theimplement, and while the plow is being turned the disk may be reversed for` the return furrow.

Itwill be understood that in practice modifications of the specific construction shown may be made and that any suitable materials and proportions may be used for the various parts Without departing from the spirit of the invention.

What is claimed is- 1. A plow comprisinga beam having a disk connected thereto for adjustment in a horizontal plane, an axle having supportingwheels, rods connected to the axle and having pivotal connection with the beam, arms connected to the beam, and extending at opposite sides thereof and below the axle, and levers pivoted to the axle and connected to the arms for raising and lowering the latter to tilt the beam and therewith the disk in opposite directions.

2. A plow comprising an arched axle provided with supporting-Wheels, a beam having a disk connected thereto for adjustment in a horizon tal plane, braces connected to the arch and having pivotal connection with the beam, arms connected to the beam and extending at opposite sides thereof and having ingers directed upwardly at opposite sides of the axle, and levers pivoted to the axle and having connections ,with the fingers to adjust the arms and tilt the beam and therewith the disk.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIE H. C. SCHUBERT.
