ANDREW E. JESTER, OF JACKSON, TENNESSEE[ IMPROVEMENT IN PLWS.

Specification forming part of Letters Patent No. 176,138, dated April 18, 1876 application filed September 14, 1875.

W To all whom it may concern;

Be it known that I, ANDREW E. J ESTER, of Jackson, in the county of Madison and in the State of Tennessee, have invented certain new and useful Improvements in Plows; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters ot reference marked thereon, making a part of this specification.

The nature of my invention consists in the mode of securing the cutter and the mode of regulating the wings of the plow, all of which will be hereinafter more fully set forth.

In the annexed drawing, making part of this specification, Figure 1 represents a perspective view; Fig. 2, a longitudinal section, and

Fig. 3 a back view of the plow foot and wings.

In thefigures, A represents the beam, and B the foot, of a shovel-plow. To the foot B is attached and secured permanently the shovel G. Just above the upper edge of the shovel C are two wings, DD, which are hinged at their inner ends to the foot B. I 1 represent two bars or bolts, which pass through -from the back of the foot, and whose forward ends rest against the back of.the wings and sup port them in any position it may be necessary to place them. These two bolts I I are caught under the head ot the curved braco J, which passes through the foot, and then through the beam, in order to more secure] y connect them together.

To vary the anglc of the wings, to make the plow cut a larger or smaller furrow, it is only necessary to loosen up the nut on brace J, draw back or push up the bars I I to strike against the back of the wings, and then tight en up the brace J again, so as to hold them tirmly in place.

Upon top of the beam are placed two slotted metallic plates, a and d, and on the under side of the beam is a metallic loop or plate, e. The cutter or, colter -passes through the slots in these platos, and isby them held securely in the position it is desired to be held, without wedges or wear and tear on the wood of the beam. These platos are securely held in place on the beam by means of suitable bolts, which pass through for that purpose; and by changing them, or moving them forward or backward, the angle or inclination of thecutter can be changed, as also its distance to or from the foot B.

K represents a three or four pronged fender, which is formed n the end of a rod, ac. This rod is secured to the beam by a suitable bolt. This fender reaches hack behind the wings D, and serves to protect the tender plants which are being plowed from the falling of heavy clods, while it allows the light earth to pass between its prongs and drop about the plants.

The fender is easily adjusted to its dcsired position.by means of the bolt which confines it to the beam.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-* 1. The wings D D, hinged to the plow-standard, the bars I I, and brace J, in combination with the foot B and its shovel-blade, as and for the purpose set forth.

2. The slotted plate a d, set-screw b, and theplate or loop e, in combination with the beam, for holding andadjusting the cutter, as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 12th day of August, 1875.

A. E. JESTER.
