My invention relates to improvements in plows, and more particularly to moldboards therefor.

The primary object of the invention, broadly stated, is to equip hand, or walking, plows for turning up the furrow slice further than can be accomplished with the usual types of moldboards, whereby plows so equipped are better adapted for plowing on hill or mountain sides.

Another object is to equip the ordinary hand, or walking, plow with an auxiliary moldboard manipulative laterally into different'set positions for co-operative relation with the usual moldboard to throw or turn the slice to varied extents.

Still another object is to provide an auxiliary moldboard manipulative as above described, together with easily operative devices for manipulating the same into different set positions, the auxiliary moldboard and devices being readily attachable to either right or left hand walking plows.

Other and subordinate objects, together with the exact nature of my improvements, will be clearly understood when the following description and claims are read with reference to the drawings accompanying and forming part of this specification.

In said drawings:

Figure 1 is a View in top plan illustrating the usual type of hand or walking plow equipped according to my invention.

Figure 2 is a view in side elevation.

Figure 3 is a view in transverse section taken on the line 33 of Figure 1 looking in the direction indicated by the arrows.

Figure 4 is a fragmentary view in horizontal section taken on the line 44 of Figure 2 looking downwardly, and

Figure 5 is a view similar to Figure 4 of a modification of the invention.

Referring to the drawings by numerals, the type of plow which has been illustrated as equipped with my invention, comprises the usual point I, share 2, moldboard 3, and land side 4. The handle bars 5 are bolted to the moldboard 3 and the land side 4, respectively, by means of bolts 6 on the moldboard side and bolts 1 on the other side. The beam 8 is bolted at its rear end, as at 9, to a bar l secured to the handle bars transversely thereof, as by bolts l The front end of the beam 8 is secured to the share 2 by means of a bracket l2 and a bolt l3.

My auxiliary moldboard I4 is mounted, as presently described, to extend rearwardly and laterally of the moldboard 3 and above the rear end of the same and to be clamped at its front end against said moldboard 3. The mounting for the auxiliary moldboard l4 comprises a pair of upper and lower clamping bars l5 and it, respectively, clamped at their ends upon opposite sides of the handle bars 5 by bolts I? to extend transversely of said bars. A hinged bar I8 is pivotally connected, as at l9, between extensions of said clamping bars and bolted to the rear side of the auxiliary moldboard, as by bolts 26. The arrangement of the described mounting is such that the auxiliary moldboard M may be swung inwardly or outwardly into different positions for co-operation with the moldboard 3 to throw the furrow slice to different extents. In the limit of its outward movement it is clamped against the rear end of the moldboard 3.

The auxiliary moldboard I4 is manipulated into different positions and set into the same by means of the following. A setting lever 2| is pivotally mounted at its front end, as at 22, to extend rearwardly between the handle bars 5. An angle bracket 23 is secured to the hinged bar 38. A pair of links 24 are pivotally connected, as at 25, to the lever 2| adjacent the front end thereof and upon opposite sides of the same and similarly pivoted to the angle bracket 23, as at 26. The rear end of the setting lever 2| is clamped between a pair of upper and lower detent bars 2'! and 28, respectively, the upper one of which is secured at its opposite ends to the handle bars 5, respectively, by means of shackle bolts 29. The lower clamping bar 28 is yieldingly urged upwardly by means of a pair of bolts 38 passing through said detent bars, adjacent the opposite ends thereof, and tension springs 3| surrounding said bolts and interposed between the upper ends thereof and the bar 21. The upper detent bar 21 is provided with a series of notches 32 in its lower edge into which the setting lever 2| is urged by the bar 28 in the different set positions of said lever and auxiliary moldboard. The notches 32 are so arranged that the setting lever 2| has three set positions upon each side of the center of said bar. Those upon one side of the center are for use when the auxiliary moldboard is attached to the right hand plow, and those upon the other side for use in connection with the left hand plow. As will be understood, the innermost position of the lever 2| upon either side of said center throws the auxiliary moldboard |4 into an ineffective position. The lever 2| may be released from the notches 32 by pressing it downwardly.

In mounting the auxiliary moldboard Hi upon right or left hand plows, it is merely necessary to reverse the position of the clamping bars 5 and I6 so that said board is disposed upon the appropriate side of the plow and to reverse the connecting links 24 so that they establish connection between the angle bracket 23 and the setting lever 2| upon the appropriate side of said lever.

In the modification shown in Figure 5, the hinged bar I8 is eliminated and the auxiliary moldboard 33 is provided at its rear edge with a hinged ear 34 pivoted to the clamping bars, as indicated at 35.

The foregoing detailed description will, it is believed, suifice to impart a clear understand ing of my invention.

It is to be understood, however, that the present disclosure is illustrative rather than restrictive and that right is herein reserved to modifications in details further than that described falling within the scope of the claims appended hereto.

What I claim is:

1. In a plow including its moldboard and handle bars, an auxiliary moldboard therefor, pivot means carried by one of the handle bars upon which said auxiliary moldboard is hingedly mounted behind the first mentioned moldboard in overlapping relation thereto and for swinging movement toward and away from the same into different set positions, and means for swinging said auxiliary moldboard into said positions.

2. An attachment for a plow including its moldboard and handle bars comprising, an auxiliary moldboard for cooperation with the moldboard of the plow, pivot means for connection with one handle bar of the plow for carrying the forward end of the auxiliary moldboard adjacent to said moldboard of the plow, and means cooperating with the auxiliary moldboard for swinging it into a plurality of positions with respect to the moldboard of the plow.

3. In a plow including handle bars and a moldboard, an auxiliary moldboard hingedly mounted on one handle bar behind the first mentioned moldboard in overlapping relation thereto and to swing against and away from the same, and means for swinging said auxiliary moldboard including, a lever pivotally mounted intermediate the handle bars to swing transversely thereof,

and means for holding said lever in difierent po- 1 sitions including, a pair of detent bars extending between the handle bars and engaging opposite sides of said lever, respectively, one of said detent bars being provided with notches in its lower edge, and the other of said detent bars being mounted on the notched bar and tensioned for downward yielding movement thereon.

l. In a plow including handle bars and a moldboard, a pair of clamping bars extending transversely of saidhandle bars in the rear of the moldboard and upon opposite sides of said handle bars, respectively, an auxiliary moldboard hinged between said clamping bars to swing thereon towards and away from the first mentioned moldboard and in overlapping relation to the same, and means for swinging said auxiliary moldboard including, a lever pivoted at one end between said clamping bars for swinging movement transversely of and between the handle bars, operating connections between said lever and the auxiliary moldboard, and means for holding said lever in clifierent positions.

5. In a plow including handle bars and a moldboard, a pair of clamping bars extending transversely of said handle bars in the rear of the moldboard and upon opposite sides of said handle bars, respectively, an auxiliary moldboard hinged between said clamping bars to swing thereon towards and away from the first mentioned moldboard and in overlapping relation to the same, and means for swinging said auxiliary moldboard including, a lever pivoted at one end between said clamping bars for swinging move ment transversely of and between the handle bars, operating connections between said lever and the auxiliary moldboard, and means for holding said lever in different positions including, a pair of detent bars extending between the handle bars and engaging opposite sides of said lever, respectively, one of said detent bars being provided with notches in its lower edge, and the other of said detent bars being mounted on the notch bar and tensioned for downward yielding movement thereon.
