" Application man a-20,1914. Serial No. 833,259.

To all whom it may concern:

Be it known that I, JOHN Hnrr ann, a citizen of the United States, residlng at SaXton, in the county of Bedford and State of Pennsylvania, have invented a new" and useful Plow, of which thefollowing is a specification. 1 V

The present lnvention appertains to plows or earth tilling implements, and aims to provide a novel and improved device of that character.

The present invention contemplates the provision of aunique cutter attached to the shovel blade of a plow in a peculiar and effective manner, whereby the plow will be,

tion, in order'to enhance the utility of the plow, and to provide a structure which will be comparatively slmple and inexpensive, as

well as being practical,-convenient and efficient in its use.

lVith the foregoing and other objects in view which will appear as the descrlptlon proceeds, the invention resides in the combination and arrangement of parts and 1n the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing fro-m the spirit of the invent on.

The invention has been illustrated in its preferred embodiment in the accompanying drawing, wherein Figure 1 is a side elevation of the improved plow. Figs. 2 and 3 are sectional views taken on the lines 22 and 3-3, respectively, of Fig. 1.

The present implement embodles a suitable beam 1 having a standard 2 attached to its rear end, and having handles 3 attached thereto in advance of its rear end and between which the upper end of the standard 2 is secured in any suitable manner.

A stay rod 4 is preferably provided for holding the lower portion of the standard 2 in place, the ends of the stay rod 4: being engaged through the beam 1 and standard 2, so that the intermediate portion of the rod 4:

will extend diagonally or obliquely between the body of the beam 1 and the lower or depending portion of the standard 2. A nut 5 is preferably threaded on the rear end of the rod 4 to hold the lower portion of the ard to be adjusted by tightening or loosening the nut5. The plow further includes a shovel blade 6, which is preferably curved slightly, and seated against the lower curved portion of the standard 2, the upper end of the blade 6 having a lug 7 engaged upwardly through a staple or keeper 8 engaged to the forward side of the standard 2 below the stay rods. The central portion ofthe blade 6 is secured firmly to the lower portion of the standard 2, by means of a bolt 9 engaged through the standard 2 and having a countersunk head 10 at its forward end engaging in a countersunk recess within theforward side of the blade-6, in order that the head of the bolt 9 will be flush with the face of the blade. A nut or retaining element 11 is threaded or otherwise engaged upon t-herear end of the bolt 9, to clamp the blade 6 tightly against the standard, and to hold the retaining lug 7 of the blade in engagement with the keeper 8, whereby the bolt 9 and keeper 8 will hold the blade steady, and will prevent the displacement thereof relative to the standard, although the blade may be readily detached from the standard when desired.

One of the salient or cardinal features of the present invention resides in the provision of a cutter 12 disposed vertically upon the face of the blade 6, the forward edge of the cutter 12 being sharpened, and its rear or basal edge being thickened and having side flanges or lips 13 resting against the face of the blade 6. The lips 13 have their free edges sharpened, in order that the faces of the lips 13 will merge into the face of the blade 6, to provide a practically continuous surface between the side portions of the blade 6, and the lips 13. The faces or sides of the cutter 12 and its lips 13 also blend together gently, as seen in-Figs. 2 and 3, whereby there will be no obstructions or protuberances which would interfere with the action of the shovel, or which would serve to accumulate dirt and other extra neous matter.

The cutter 12 is secured to the blade 6 by means of screws or othersecuring members I standard 2 in place, and to enable the stand- 14- engaged through the lips 13 and taking into or engaged through the blade 6. A- plurality of screws or securing members 14: are preferably engaged through each of the lips 13, whereby the cutter 12 will be most effectively secured to the blade. The cutter 12 extends to the lower end of the blade 6, and tapers downwardly, in order that the forward sharpened edge of the cutter will extend to the lower end or extremity of the blade 6, as seen in Fig. 1.

In practice, the present plow is employed in the usual manner for tilling or breaking the soil, and is particularly desirable for breaking open new ground. The cutter 12 will split the soil open, whereby the soil will be thrown or deflected to the opposite sides by the cooperating lips 13 and side portions or wings of the blade 6, to thoroughly agitate or break open the soil. The cutter 12 will also sever the roots encountered thereby, so as to not only destroy the roots, but to permit the plow to continue the tilling of the soil without interference. Shouldthe cutter 12 become dull aftercontinueduse,3 the same may be sharpened, preferably-byi removing the cutter and sharpening the i same in any suitable manner. The cutter 12 i may be removed readily from the blade 6, by withdrawing or removing the securingi members 1 1. Thus, the cutter may also bei removed, when it is desired to utilize the ing basallips resting against the blade and having their edges sharpened whereby the faces of the lips merge gently into the face of the blade.

2. A shovel blade, a vertical cutter having sharpened basal lipsfitting against the face of, the blade, and securing members engaged through the said lips and through the blade.

3. A shovel blade, a vertical cuttebhavving basal lips resting against the face of the blade, and means securing the said lips to the blade, the faces of the cutter and said lips blending together gently, the free edges of the lips being sharpened whereby the faces ofthe lips merge gently into the face of the cutter, and the cutter being tapered downwardly.

In testimony that I claim the foregoing as my own, I have hereto aiiixed mysignature in the presence of two witnesses.
