RICHARD H. CRUMMETT, O'F MONTEREY, VIRGINIA.

CONVERTIBLE HILLSIDE PLOW.

Application filed August 11, 1921.

To all whom it may concern:

Be it known that I, RIGHARD'H. CRUM- METT, a citizen of the United States, residing at Monterey, in the county of Highland and State of Virginia, have invented a new and useful Convertible Hillside Plow, of which the following is a specification.

This invention relates to reversible hillside plows, and the subject matter of the present application is designed as an improvement on the structure shown and described in the Patent No. 1,262,232, issued to H. l/V. Mullenax, of which I am now the owner.

The primary object is to provide a plow having a double mold-board capable of being reversed from the left to the right side or vice versa, to enable the use of the same upon a hillside, in the customary manner, the said mold-board being readily shiftable from one side to the other by the simple operation of afoot lever, thus leaving the hands free for other necessary purposes.

Another object is to provide means for shifting the said double mold-board, and simultaneously operating or lifting an auxiliary mold-board out of the way thereof to permit such shifting movement of the double mold-board, the auxiliary mold board being operated by a hand lever which also automatically releases a catch or looking member to rigidly hold the double moldboard in either of its positions, the said auxiliary mold-board being adjustable to fit the same to the contour of the reversible moldboard, and being adapted to snugly engage the active surface of the same and to convert the plow into an ordinary mold-board plow, when it is desired touse the same for this purpose.

A further object is to provide a plow which may be easily transported from place.

to place without the necessity for turning the same over on its side and dragging the same as is ordinarily done, the plow having an adjustable gage wheel at the forward end of the plow beam, and an adjustable trailing roller at the rearend of the shoe, to permit of moving the plow over the surface of the ground without the plow point penetrating the same, after the said gage wheel is extended downwardly by means of a hand lever.

Serial No. 491,440.

A full and completeunderstanding of the. invention may be obtained from-a consider- Specification of Letters Patent. Patented June 20 1922.

ation of the following detailed description,

taken in connection with the accompanying drawings forming a part of this specification, it'being understood that while-the drawings show a practical form of the invention, the latter is not to be confined to strict conformity therewith, but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention, as

specifically pointed out in the appended claims. I

In the drawings in which similar reference characters designate corresponding parts throughout the several figures:

Figure 1 is a side elevation of a plow constructed in accordance with the invention. Figure2 is a plan view thereof. p Figure 3 is an enlarged elevation of the plow looking from the opposite direction, the beam being broken away, as well as the handles, a

Figure 4k is a rear elevation of the subject matter of Figure '3, v

Figure 5 is ahorizontal sectional view taken on the line 5- 5 of Figure 3.

Figure 6 is a detail perspective view of the locking mechanism for automatically engaging the plow in either position when operated by the hand lever for the purpose.

In the operation of the plow disclosed in unlocking movement of the locking member I for the double mold-board, topermit the same to be swung from one side of the plow to the other, as when engaged in plowing the soil on a hillside, and after the double board has reached its active position on either side, by a reverse movement of said hand lever, the auxiliary board is caused to seat itself against the curved face of the reversible mold-board at the same time the said locking means is projected into engagement with the swinging supporting frame for the rear end of the said double board.

The improved plow includes in its construction a plow beam '1 having, adjacent to its forward or clevis end, an adjustable gage wheel 2, mounted on a vertically swinging V lever 3, and controlled by a hand-lever a fulcrumed near the rear end of the plow beam and adjacent to the handles 5, through the medium'of a connecting link 6. No novelty I is'claimed for this feature.

The rear endof the plow beam is turned downwardly and forwardly, in the usual manner, to form a standard 1 which is provided with a forwardly tapered shoe 7, adapted to bear upon the plowed soil in the customary manner, and having at its forward end, a longitudinally disposed trunnion 8, preferably cast integral therewith, and said shoe carrying, at its rear, widened end, when transporting the plow from field to field; a roller9'projecting slightly below the lower face of the shoe, whose side walls extend slightly beyond the rear face of the plow standard and between which the said roller -9 is located, the roller being carried by a removable plate 10 held by a thumb-nut 11, which permits the ready removal of the roller when it is desired to commence plowing operations.

The shoe 7 ends,'and in'advance of the plow standard, with an upstanding pivotal bolt 12, suitably secured in the said shoe and having a rear wardly directed, horizontal bearing portion 13 comprising a trunnion co-acting with the forward trunnion 8 to permit the swinging action of the double, reversible mold-board 1 1. The mold-board 1 1 has, at its forward portion, a suitable socket for the reception of said trunnion 8, and is provided, at its rear end, with a yoke 15, comprising angularly disposed arms 16 suitably secured, at their outer, free ends, to the inner or convex faces of the wings ofthe double mold-board, and joining at their lower ends and terminating in a pivotal arm 17, having a horizontal aperture for the reception of the trunnion 13, so that the double mold-board, which carries the usual plow point'll may be readily swung from side to side, as will be readily understood.

In order to swing the double mold-board,

a foot-operated rock-shaft formed of' a stout rod or bar of iron, is bent to form a longitudinally disposed bearing portion 18 mounted in a suitable aperture, provided in the lower end of the plow standard 1*, the rear end havinga crank-arm 19 formed thereon and adapted to be actuated by the foot of the is provided intermediate its formed between the arms 16 of the yoke 15, I

nut 21, in order to strengthen the yoke 15' during the operation of the plow.

The auxiliary mold-board '25 which is adapted to operate in the same manner and for the same purpose as that shown and described in the'aforesaid patent, is carriedby an upstanding staff 26, shiftable about its axis by a hand-lever 27, and slidable in a substantially vertical direction by another hand-lever 28 pivoted at its lower end upon a transverse bolt 29 carried by the plow beam, and which may serve also as a pivotal bolt for the aforesaid lever 4:. Thehand lever 28 has a forwardly extending arm 30 suitably connected to the staff 26, and the said lever may be actuated to elevate the said staff together with the rotary shifting lever 27 and the auxiliary mold-board, as clearly shown in Figure 3 of the drawings."

The hand levers 4 and 28 are provided with the usual latches and toothed segments,

and'the latter lever is further'conneoted by an'adjustable link 31, to a bell-crank lever 32, fulcrumed at its angle upona bracket 32 between the handles 5 of theplow, the other arm of the bell-crank lever extending down- I wardly to the rear end of the plow standard 1, and connected to the rear end of a' rod 33, passing through a suitable opening formed in the plow standard, from front to rear thereof, the forward end of thesaid 7 rod 33 being curved downwardly and connected to a locking member designated as a whole by the reference numeral 34.

The locking member which is'formed of suitable rod iron, comprises forwardly extending, spaced arms 35, joined at their rear ends by a transversely disposed gearing'portion 36 pivotally mounted within a bearing plate 37, which is seouredto the front facevof' the plow standard at a point in horizontal alignment with the intermediate portions of the yoke arms 16, as the latter are swung from side to side in the manner heretofore described. 7

At their forward ends the arms 35 carry, each, a fork 38, one or the other of which is adapted to engage the said arm 16, that is, at the time, in substantially vertical position, as illustrated in Figure 6 of'the drawings, and intermediate oftheir ends. The said arms 35 are provided with upstanding ears 39, in which is pivotally' mounted a rock-shaft 10 having an intermediate up; standing ear l-l fOI' connection with the forwardly extending downturned end of the aforesaid rod 33, an expansion spring 42 being mounted between the front face of the plow standard and the said ear ll, and in surrounding relation to said rod 33, for the purpose of normally maintaining the locking member 34 in a lowered position, so that one of the forks 38 may engage one of the arms 16 of the yoke, as will be readilyunderstood.

As has been stated before, the double duty performed by the hand-lever 28 is the principal feature desired to be embraced in this application, and a detailed description of the operation of the other features shown herein and described in a measure, is deemed un necessary. I

When the hand lever 28 is forced to the rear or towards the handles 5, the forwardly extending arms 30 act to elevate the auxiliary moldboard 25, as will be clearly seen. At the same time the link 31, which is provided with a plurality of perforations 31 for adjusting the bolt 31", which traverses one of the perforations 32 of the bell-crank lever 32, is depressed to rock said bell-crank lever about its pivot on the bracket 32, when the lower end of the same will pull the rod 33 rearwardly against the resistance of the spring 12, and draw the locking member 3a upwardly about its pivot 36, when the fork 38 will be disengaged from the arm 16, and the yoke 15, together with the double moldboard, may be swung to the opposite side of the plow, the auxiliary mold-board having, by this time, been elevate-d sufliciently to allow of such swinging action.

From the foregoing it will be seen that important improvements have been applied to the plow of the aforesaid patent and that the manner of operating and locking the reversible double moldboard has been reduced to a single operation of the hand and the foot, and, in addition, the removable rollerbearing plate 10 at the rear of the plow standard may be easily applied in position to elevate the plow point 14* above the surface of the ground, after the colter wheel 2 has been lowered by means of the hand-lever 4, when the plow may be transported in an upright position.

What is claimed is:

1. In a plow of the character described, the combination with a reversible moldboard, of an auxiliary mold-board movable into position for engagement with said reversible mold-board, a locking means for holding the reversible mold-board in its adjusted position, and a manually operated means for simultaneously control'l i ng said locking means and mold-board.
