SPECIFICATION forming part of Letters Patent No. 544,845, dated August 20, 1895.

Application filed April 30, 1895; 'Serial No. 547,660. (No model.)

ToaZZ whom it may concern: l

Be-it known that we, MARTIN M. COCHRAN and SAMUEL ADAMS, citizens of the United States, residing at Toll Gate, in the county of Ritchie and State of West Virginia, have invented certain new and useful Improvements in Flows; and we do 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 makeand use the same. 9 1

Our invention relates to improvements int plows, and more particularly to that class of plows known as shovel-plows; and it has for its general object to provide a plow embodying a root-cutter, arranged in advance of its shovel, and a cheap, simple, and advantageous means through the medium of which the root-cutter may be adjustably fixed at various distances above and at various distances in advance of the point of the shovel, such means being also adapted to permit of a ready removal of the cutter from the plow when desired, as will be presently described.

Other obj ects and advantages of the invention will be fully understood from the following description and claims, when taken in conjunction with the annexed drawings, in which- Figure 1 is a side elevation, partly in sec- 4 are sections taken in the planes indicated I lliy the lines or w, y y, and 2 z, respective1y,'of

In the said drawings similar letters designate corresponding parts in all of the views.

A indicates the beam of our improved plow, which is provided at an intermediate point of its length with a longitudinal vertical slot (1, and is also provided at or adjacent to its forward end with apertures b.

13 indicates a clevis which is provided with two pairs of vertically aligned apertures and has its lower apertures threaded. I

0 indicates the connecting-bolt which extends through the forward apertures of the clevis and the forward aperture b of the beam and has its lower end threaded to engage the threaded lower aperture of the clevis.

D indicates an auxiliary connecting-bolt which extends through the rear apertures of ingjaws o.

the clevis and beam and is threaded to en- F, and is designedto be connected by a suit- 7 able cross-bar c with the'handles d which extend rearwardly from tliebeam, as illustrated.

Gindicates the root-cutter or cutting-blade of our improvements, which is arranged in advance of the shovel F and extends through the slot or of the beam A, as better shown in Fig. 1.

H indicates the bar or'arm which connects the upper end of the blade G and the stock, and I indicates the strap or bar which connects the lower portion of the blade G and the stock. The rear portion of the bar H, which extends through the opening f of the stock E, is of a circular form in cross-section and is threaded, as indicated by g and h, for the engagement of the securing and adjusting nuts rlj, which are arranged in front and rear of the stock, as shown. The forward end of said bar H is fiattenedand bifurcated, as

better shown in Fig. 2, so as to form the resilient clamping-jaws m, which are adapted to receive the blade G between them and are designed to be clamped upon said blade by the bolt 01, which extends through them and is provided with a nut 19, as shown. The bar I, which extends through the stockE below the beam, has but one threaded portionq as indicated bys, and at its forward end, as 1 indicated by If, so as to enable it to brace the connection of the stock E to the beam A and strengthen the connection of the clevis B to said beam. At an intermediate point of its length said bar I is slotted vertically, as indicated by a, so as to form the resilient clamp- (Better shown in Fig. 3.) These jaws 'u are designed to receive the blade G between them, and they are adapted to he clamped against said blade by the transverse bolts w m, which extendthrough them and are provided with nuts, as shown. The bolt D for connecting the clevis B and the beam A is made in the form of a wrench, as before described, so that it may be removed when desired and employed to turn the nuts 63' on the cutting-blade G from the plow, or when it is desired to adjust the same vertically, it is simply necessary to loosen (not remove) the nuts on the bolts n w 00, when the jaws m 1;, by tending to spring outward, will release the cutting-blade, so as to permit a ready removal or free vertical adjustment of the same. When the blade has been adjusted to the desired position, it may be adjustably fixed in such position by tightening the nuts on the bolts, so as to clamp the jaws against the blade.

When it is desired to adjust the cuttingblade G forward or rearward with respect to the shovel or plow F, it is simply necessary to loosen the nuts on the bol'tsw a: and then move the bar H, through the medium of its nuts 71 j, until the cutting-blade rests in the desired position, when it may be adjustably fixed in such position by tightening the nuts t'j and the nuts on the bolts w 00.

It will be observed from the foregoing description, takenin conjunction with the drawings, that our improved plow, while very cheap and simple, is very strong and durable; and, it will also be observed that by reason of our peculiar construction the blade for cutting roots and the like may be materially adjusted to suit different conditions, which is an important advantage.

Having described our invention, what we claim, and desire to secure by Letters Patent, 1s-

1. In a plow, the combination of the beam having the longitudinal, vertical slot, the stock or standard connected to the beam and carrying a plow, a bar connected to and extending forwardly from the stock above the beam and having resilient clamping jaws at .its forward end, a transverse bolt taking through the clamping jaws of the bar and s c/provided with a nut, a bar connected to and extending forwardly from the stock below the beam and having resilient clamping jaws,a transverse bolt taking through said jaws and provided with a nut, and the root cutting blade arranged between the resilient clamping jaws of the upper and lower bars at the side of the bolts and extending through the longitddinal, vertical slot of the beam, substantially as specified.

2. The plow described comprising the beam having the longitudinal vertical slot, the stock or standard connected to the beam and carryingplow, a bar connected to and extending forwardly from the stock above the beam and having resilient clamping jaws and means for pressing said jaws inwardly, a clevis, the bar connected to and extending forwardly from the stock below the beam and having resilient clamping jaws at an intermediate point of its length and means for pressing said jaws inwardly a bolt taking through andconnecting the forward end of said bar, the clevis and the beam, and the root cutting blade arranged between the clamping jaws of the upper and lower bars at the side of the means for pressingsaid jaws inwardlyand extending through the longitudinal, vertical slot of the beam, substantially as specified.

3. Ina plow, the combination of the beam having the longitudinal vertical slot, the stock or standard connected to the beam and carrying a plow, the bar H, extending through the stock and having threads at its rear end and at an intermediate point of its length and provided with nuts engaging said threads and resting on opposite sides of the stock; said bar also having resilient clamping jaws at its forward end, a transverse bolt taking through the resilient clamping jaws of the bar H, and provided with'a nut, a bar connected to and extending forwardly from the stock below. the beam and having resilient clamping jaws, a transverse bolt taking through said jaws and provided with a nut, and the root cutting blade arranged between the clamping jaws of the upper and lower bars at the side of the transverse bolts and extending through the longitudinal vertical slot of the beam, substantially as specified.

In testimony whereof we affix oursignatures in presence of two witnesses.
