IMPROVEMENT IN GRAIN-DRILLS.

Specification forming part of Letters Patent No. 154,053, dated August 11, 1874,' application filed August 8, 1873.

The same letters are employed in the designation of identical parts.

This improvement relates to that part of the mechanism of a grain -drill which is employed in shifting the hoes from a single to a double row, or vice versa.

The hoes A are attached to drag-bars B, respectively' hinged to the sliding beam C and Athe stationary beam O. The sliding beam has its ends secured in guides or ways on the main frame, so as to permit it to be freely moved, either forward, to arrange the hoes in a zigzag line, or back, to bring them into straight order. This adjustment is effected by means of the rod D, which is secured to the movable beam C', from which it extends rearward to and slightly beyond the rear end of the frame, at which point it is provided with a handle for the operator to grasp in shifting or adjusting the hoes. The outer portion of this rod rests in a recess formed in the upper surface of the cross-beam X of the frame of the machine, and, if necessary, maybe prevented from rising out of said recess by a cap, Y, secured to the frame, and made to pass over it, as shown in Fig. 3. From the bottom of the recess in which the rod D moves a short stud or pin projects upward through holes formed in the rod D, said holes being arranged with reference to the holding of the hoes in position when they have been adjusted either in a single or in a double rank.

Y From the above description, and upon reference to the drawing, it will be seen that the arrangement of the rod and stud or pin is such that, by a longitudinal movement of the their readjusted order; and that this is effected without the aid of any additional parts, and without imparti-n g to the rod any other movement than those just described, in which respect it diers from any `other shifting device known to me.

While I regard the position of the rod so as to permit it to be operated immediately behind the machine as especially important, other shifting devices may be adopted, either alone or in combination with the one already described. .Thus a shaft, G, oscillating in bearings in the side pieces of the frame, may

have arms G1 projecting'downward, which are connected to the sliding beam O by means of the links G2.

The arms G1 may be fixed, so as to secure the sliding beam in position, by bolts passing through said arms, and through the main frame, or in any other suitable manner.

I am aware'that it is not a novel feature in grain-drills` to so arrange a rod in connection therewith that the adjustment of the hoes can be ei'ected from the rear of the machine, devices for effecting such a result beingl shown in patents granted to Thomas, Mast, and Gardner, August 3, 1869; to G. S. Ball, November 26, 1872; and to C. E. Patrick, February 25, 1873. I do not, therefore, claim this feature of the invention, but intend to limit myself to the particular devices which I employ.

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination, in a graiiadrill the hoes of which are arranged to be shifted from a single to a double rank, and the reverse, of a movable bar, to which a portion of the hoes are attached, a rod extending rearward therefrom, which is made to both move and lock the hoes in position by a longitudinal move- -ment thereof, a locking stud or pin, which holds the rod in its adjusted positions, and a xed bar for receiving the locking-pin, the parts all being constructed and arranged to operate substantially as and for-the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
