Specification of Letters Patent.

Patented Dec. 25, 1906.

.To all whom t may concern,.-

Be it known that I, IRENE DESY, a citizen of the United States, residing at Lewistown, in the county of Fergus and State of Montana, have invented new and useful Improvements in Sulky-Plows, of which the following is a specification.

This invention hasA relation to sulkyi-plows equipped with a plurality of plows-that is, furrow forming and turning means-and other various necessary appliances.

It is the object of my invention to provide improvements in. the class of plows mentioned that will render the same more efficient and more easily operated and controlled than plows of the same typeas heretofore constructed.

To these ends my invention consists of various improvements having in view the lessening of t e draft, the perfect turning of the ground, especially sod, and a construction whereby the same number of horses can plow or break ground to a much greater. width than heretofore, and the provision of an improved plow-frame and sulky-frame and' means whereby the plows and sulky can be raised with reater facility and ease than heretofore, allg as will lbe hereinafter fully described, and subsequently pointed out in the subjoined claims.

In the accompanying drawings, forming a part of this specification, Figure 1 is a perspective view of the invention looking from near the rear toward the front. Fig. 2 is a plan view of the same. Fig. S'is'a sectional view taken in the line 3 Brof Fig. 4. Fig. 4 is a sectional side elevation taken in the plane' 4 4 of Fig.2.v Fig. 5 isa sectional detail view taken in the plane of the axis of a disk .moldboard and showing the relationship of the latter to the share and colter or sodcutter. Fig. 6 is a sectional detail' view, on an enlarged scale, vof parts portrayed in Fig.

3, assisting to show the means for raisingand lowering the plow-frames. Fig. 7 is a sectional detailview of fewer parts than is intended to b'e represented in Fig. 4 with a design to make clear the relationship of the pivotal lever and its connections whereby the plow-frame is raised and lowered.

While the title given to the invention is sulky plowsf andk the specification discusses it as such, it is to be understood that the invention is not confined to plows of any particulartype. So far as the principles of the invention may admit it may be employed as a walking-plow, or parts may be used in vdifferent plows if found applicable -in other connections without surrender of any rights guaranteed me by law.

' In explanation of the construction and mode of operation of the improvements effected by me let a represent the sulky-frame, which is constructed of parallel side bars offset and widened at la point substantially where the supporting-wheel b is met, connected at their forward ends by a straight bar c and at their rear ends by an obliquelyextended bar d. A cross-rod e assists in' bracing or stiffening the sulky-frame laterally at a point where it is subjected to the greatest lateral strain.

The plow frame is arranged on a lower plane than the sulky-frame and consists of the central draft-bardf, extending from the front end, where the raft-clevis is attached, to the rear, where it is ivenarecurvate bend downward and forwar to near the ground.

4The said draft-bar is composed of one piece of steel or similar metal, and the plowshareg is attached to the lower rearward end, and a sod-cutter or colter h is connected withthe landside of the plow. The share has a V- shaped notch formed in its rear end, and the edge of the rotary moldboard or furrow-turning disk/i of each low is arranged ust behind the share, to the feft of the V-shaped notch j, and with its forward edge substantially in line with the sod-cutter 7L.

Each plow and its adjuncts is connected with a draft-bar 7c, having a recurvate bend at its rear end, like the central draft-bar, and is arranged laterally lof the latter bar and parallel with it and connected at its forward end either immediately or mediately through another lateral bar by an angular bend Z. The lateral bars k extend from substantially the line in which the widening offset is formed in the sulky-frame rearwardly to aline substantially coinciding with the lane of the rear connecting-bar of the sul y-frame, so that the line of plows is on an angle with respect to the line of draft, the plow on the ex- IOO ltreme. right being farthest forward. .Morev over, the lateral bars 7c may be arranged on both sides of the central draft-bar in number and order suited to circumstances and convenience. m designates obliquely-arranged braceebars between the lateral bars and cene tral bar to brace and keep said bars in proper place. The arrangement of these brace-bars is such as to enable them to most effectively perform the functions required of them.

The rotary moldboards or disks are each arranged on an arm n of an angular bar, the other arm of which is secured to the recurvate bend of its draft-bar, and the said disks are left to turn or be turned by the friction of the ground thereagainst. The shares are securedl to the ends of the draft-bars, which latter in their bends become substantial Standards to the shares and maintain the same in flat order-that is, so as to extend parallel with the surface of the ground-and they cut the ground in that order, while the colter cuts it vertically on a line coincident with the inside of the furrow, and the rotary Inoldboard coming in contact therewith turns it over. This, in connection with other contrivances-as, for instance, the described arrangement of the rotary moldboard with respect to the sod-cutter and the rear of the share-makes the plowing and turning of a furrow easy, vas hereinbefore stated.

An arm ois connected at one end to a plowstandard and having the other end free and flattened, which free end extends over the disk and in close proximity to the face of the disk, so as to scrape off or remove the adher ing ground or refuse therefrom.

p' designates an overbar having right-angular slotted and curved ends r depending therefrom, which are secured to the side bars of the sulky-frarne. A bar s below the overbar passes loosely through holes formed in pieces t, connected at their lower ends with the draft-bars, and the gudgeons at the end of the said bar s extend into the slots of the curved ends or arms r of the overbar p, Toggle-levers u are connected with the overbar p and the bar s through the intervention of suitable means-as, for instance, by clips 1, adapted to pivot and slide upon a common bail 2, fixed to said overbar p, and by sleeves 3, loosely arranged upon said bar s and having pivoted thereto said toggle-levers. A pair of rods 12, standing apart at their lower ends and pivoted upon the bar s at said ends, are brought together at their upper ends and pivoted upon the forward end of a curved lever fw, which is fulcrumed upon suitable means on the upper side of the overbar.

1 j is a sulky-seat secured on the upper end of a spring-bar j and attached at its lower end to the sulky-frame. (See Fig. 1.) At the right-hand side of the seat is a lever w for raising and lowering the plow-frame in the Sulky-frame. The said lever w is fulerumed near its center between a standard p2,extending up from the overbar 2), and the upper end p3 of a brace-bar p4, formed similarly to the standard p'-. In Fig. 7 the stand ard p2 is of exactly the same form as the part p3 and is just beyond the standard p, so that it is not seen. The brace-bar p4 extends rearwardly and downwardly and is at tached at its rear end to the sulky-iramc. The lever w is provided at its forward end with a downward extension in the form of an arm w', which is provided with numerous holes wx, adapting it to be adjustably pivoted to the converging ends of therods c, secured through the means shown to the sulky-frame. By operating the lever w on its fulcrum its pivotal connection at its front end with the sulky-frame will permit of raising and lowering the plowframe, as will be readily understood.

Qc is a toothed segment, the upper end of which is supported from the overbar p, and its lower end is secured to the outside of the brace-bar p1. The lever w has a detcnt or dog y operating in bearings on its outside, the inner end of which detent is adapted to engage the peripheral notches of the segment, and thus provide for holding the lever in any position to which it may be moved. A wire s connects the handle a with said dog for its actuation, which handle a is arranged closely to the handle 'w3 `of the lever w, so that when the operator takes hold of the lever-handle w3 to work it he may likewise take hold of the handle a and manipulate it and the dog y. By the means last described it will be seen that as said lever w is suitably operated the plows and )low-frame may be raised and lowered at will with respect to the sulky-frame, so that the implement as a whole may be taken upon the road or else where from place to place without having the plows come into contact with the ground.

b designates a lever fulcrumcd upon the frame A, as at c2, and pivotally connected to the arm c', projecting up from the axle of the wheel b, and e designates an externallytoothed arcuate bar connected at one end with the overbar and sulkyframe, with which a dog f is adapted to engage and. hold the lever b in adjusted position, said dog being connected with a handle g in close proximity to the handle b, so that the dogf may be manipulated substantially as the dog 1/ of the lever w.

A standard 7L extends vertically upward from the center of the dual lever vL, and to said standard is adjustably connected the outer end of a rod s, the inner end of which is connected. to the inner and downward extension @U2 of the lever w. A wire rod z2, having a spring wi connected.therewith, is attached at one end to the vertical lug w on the lever w, and the rod z2 acts to draw the lever in the direction indicated by the arrow and to depress the inner end of the dual lever lOO ltheir forward portions,

hf. 4 The operator with his feet onthe dual lever may actuate it as desiredagainst the stress of other means, and so raise or Ylower the' plow-frame the same as by operating the lever w, all. as will be understood by an inspection of Fig. 7. f

Guide or caster wheels'l m have theiraXlesupports n" passing'pivotally'through laterall Y vextensions o of the sulky-frame, and a rod p eHects' .connection between crank-'arms .q2 gx, forming upper end terminals of` said An arm n is connected at one of its ends to the side of each draft-bar at the point of its recurvate bend and is rounded at its other or free end; The said arm is bent angularly around the rear edge of the draft-bar and projects into a tubular bearing from the center of the back of the disk t', as shown in Fig. 5, by whichr means the disk is maintained in place, as hereinbefore described.

The head of the implement will be provided with suitable means for attaching and adjustingthe' draft-clevis and other necessary means.
