SIDE-HILL' PLOW.

SPECIFICATION forming part Of Letters Patent NO. 540,846, dated June 1 1, 1 895.

Application fi e November 14, 1894:. Serial No. 523,768- (No model.)

Io all whom it may concern.-

Be it known that 1, WILLIAM STRAIT, a citizen of the United States, residing at Elmira, in the county of Ohemung and State of New York, have invented certain new and useful Improvements in SideHill Plows, (Case 13;) and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to plows.

The object of my invention is to provide a sidehill plow and its reversible moldboard with novel means for shifting the colter and jointer.

Figure 1 represents a side elevation,partly broken away, of a plow embodying my invention. Fig. 2 is a sectional view on the Fig. 3 is a sectional view on the line y 'y of Fig. 1. Fig. 4 is a detail view of thefront edge of the standard. Fig.

5 is a detail side elevation of the standard and handles, showing the colter removed from its position in Fig. l and a jointer substituted therefor. Fig. 6 is a perspective view of the jointer and its operating mechanism.

The standard A is provided with an inclined fore and aft hole or opening B within which eitherthe colter O or the jointer D may operatively rest. When the colter O is used with this sidehill plow, the relation of the parts is as shown in Figs. 1, 2 and 3.

The opening B in the front of thestandard is vertically elongated, and the shank E of the colter is of similar dimensions as said opening at that point. The opening B flares laterally from the front toward the rear edge of the standard so as to provide a lateral 0s cillating motion to the colter-shank.

F are the shifting handles of the plow pivoted at any suitable point, and carrying-a plate G bolted on the under side thereof, and provided with lugs H which act, through the intervention of the lever I to oscillate and shift the colter 0 whenever the handles and the moldboard are shifted.

The lever I oscillates upon a pivot J carried in the standard and its upper end is recessed providing an openingK through which the rear end of the colter shank E projects. A curved bolt M is secured to the leverIand traverses this opening K passing through an eye in the rear end of the shank E. The lower end of lever I constitutes a projection which lies between the lugs H on the handles.

The opening K is of such lateral dimensions that the lever Ioscillates to some extent before that actuating side wall of the open- (depending in what direction the colter or jointer is tobe-shifted) comes in contact with the shank of the same for shifting it. The initial part of this motion in either direction is lost motion, the end movement of the oscillation accomplishing the shifting of the shank of the colter or jointer, such shank projecting through said opening.

In operation, when the moldboard and handles are shifted by being thrown to the right, for example, the lugs H are thrown to the left, moving the lower end of lever I in that direction, and the upper end thereof in the opposite direction, or to the right. The opening K, also moving to the right, its rear edge comes in contact with the colter shank E shifting it laterally to the right until it bears against the side wall of the opening B where it is securely held. The colter 0, being at the cpposite' end of the shaft is carried to the left for its operative position when the moldboard is thrown to the right, the colter and share being in alignment. It will be seen that a precisely reverse operation takes place when the moldboard and handles are shifted to the left. The bolt M passing through the eye of the shank holds the colterin operative position and at the same time allows a. free operative movement to the shank.

O is a lug formed on the rear of the standard which overlaps the upper edge of the lever I and aids in holding that lever in place during its movements.

When it is desired to substitute the jointer D for the colter G the latter is removed and the rotaryshank P of the jointer inserted in the opening B, said opening having circular portionsR therein within which the shank P has its bearings. The lever I is then removed, and the lever collar S is substituted and secured to the rear end of the shaft P, the collar S being received within the lug O on the standard. The casting T is then bolted on the upper end of the handles and has a pin which engages with the collar lever S for shifting the jointer when the moldlooard and handles are shifted.

I claim- 1. A colter or jointer shifting lever provided with an intermediate pivot having a projecting arm on its lower end and an opening in its upper end, within which the colter or jointer is shifted.

2. A colter or jointer shifting lever having a projecting arm on its lower end, an opening in its upper end provided with a bolt for bold- WM. STRAII. Witnesses:
