JESSE S. FELT, OF PORTLAND, MAINE.

PLOW.

SPECIFIGATEON forming part of Letters Patent No. 745,172, dated November 24, 1903.

Application filed March 16,1903.

To a. whom it may concern:

Be it known that I, JESSE S. FELT, a citizen of the United States of America, and a resident of Portland, Cumberland county, State of Maine, have invented certain new and useful Improvements in Plows, of which the following is a specification.

My invention relates to a reversible or double-pointed hillside-plow of that class using a swinging moldboard; and it relates particularly to an improvement on the plow patented to me November 8-, 1881, and numbered 249,234.

In my plow as formerly constructed the beam was pivoted to the plow proper in such a manner that when the team turned around they reversed the beam and the plow at the same time, and the plow proper had then to be reversed by hand to get the plow into position to turn the return furrow.

In my present invention the parts are so connected that the beam reverses while the plow remains stationary, the beam being pivoted to the top of the standard, so that it may be swung around in either direction without moving the plow from its position.

I illustrate my invention by means of the accompanying drawings, in which-- Figure 1 is 'a side elevation of my new plow. Fig. 2 is a plan of the plow with the beam removed. Fig. 3 is a view of the under side of the beam, showing a section on the line a; a: of Fig. 1; and Fig. 4 is a detail of the brace which holds the swinging moldboard.

A represents the beam, B the cutter, C the plow proper, having two opposite points, and D is the swinging moldboard pivoted to the side of the plow, all these parts except the beam being as shown in my prior patent.

The beam is pivoted to the top of the standard so that it can swing without reversing the plow proper by means of a pivot or bolt m, and it is locked in its two opposite positions.

- For this purpose the upper end of the stand- Serial No. 147,922. (No model.)

and connects with the bolt 2', and the rear end is bent in like manner and extends at right angles across the beam, near its under face. For the purpose of operating the sliding rod to throw the bolt I provide a cam f, pivoted to the beam by a vertical pin g. This cam has two nearly parallel straight edges, against one of which the rod presses when the bolt is in,

and a curved portion by which the bolt is pushed back when the cam is turned in either direction. For the purpose of forming a handle to operate the cam and to hold in place the swinging moldboard I provide a brace e, pivoted to the cam and having its free end formed with a dovetailed notch or hook n, which fits over the upper edge of the swinging moldboard and into a hole (1 near said edge. The pin g projects down far enough so that as the beam swings around it will catch the swinging moldboard and reverse it automatically.

The operation of the plow will be readily understood from what has been said of its construction. Then the end of the furrow is reached, the plow is run out of the furrow and the brace 6 released from engagement with the hole 01 and turned around, thus causing the cam to withdraw the bolt. The horses are now swung around on the land side of the plow, the plow remaining stationary while the beam swings, and after the beam has reached the reverse position the brace e is hooked into the hole (I of the other edge of the swinging moldboard and the bolt is allowed to snap into the opposite notch, thus holding the plow securely in its new position. As the pin g swings around with the beam it catches the edge of the swinging mold board and throws it over into its reversed position.

ating said bolt, a cam for operating said rod and a handle for turning said cam.

2. A double-pointed reversible plow having a swinging moldboard with a swinging beam pivoted at the top of the standard, a spring looking-bolt on the under side of the beam adapted to engage notches in the upper end of said standard, a sliding rod for operating said bolt, a cam for operating said rod and a brace pivoted to said cam and adapted to engage and lock the swinging moldboard in position.

3. A double-pointed reversible plow having a swinging inoldboard with a swinging beam pivoted to the top of the standard, a spring looking-bolt on the under side of the beam adapted to engage notches in the upper JESSE S. FELT. YVitnesses:
