Specification forming part of Letters Patent No. 133,202, dated November 26, 187i?.

To all whom it may concern:

Beit known that I, GEORGE S. BALL, residi ing at Dayton, in the county of Montgomery and State of Ohio, have invented a certain Improvement in Grain Drills, of which the following is a specification:

This invention relates to that class of graindrills in which the hoes may be arranged either in a straight or in la zigzag line; and my imi provement consists in the employment, in combination with an oscillating bar, to which the changeable hoes are connected, of one or more perforated bars fixed to the frame-Work of the drill, and a corresponding number of movable bolts on the oscillating bar, so arranged as to enter the perforations in the xed bars, for the purpose of locking the oscillating bar in `any required position to the said fixed bars.

It further consists in the combination, with said locking devices, of a system of levers so disposed that, by means of the hand or foot lever thereof, the oscillatin g bar may be iirst unlocked and then shifted to its new position.

Figure lis a bottom view representing so much of a grain-drill as is necessary to clearly illustrate my invention. Fig. 2 is a transverse section thereof. Fig. 3 is a transverse section of the oscilla-tin g bar at a point where it is provided with a looking-bolt.

The same letters of reference are .employed in all the figures in the designation of'identical parts.

The changeable hoes are carried by a series of drag-bars, A, and alternate with the unchangeable hoes, which are connected by the drag-bars B to the fixed crossbeam B of the frame of the drill. The drag-bars A are hin ged to the oscillating bar C, which is supported by its journals in suitable bearin gs upon the frame, and, in the example illustrated, moves over the two ixed metal bars D D, which are curved to correspond with the arc described by the under side ofthe oscillating bar (l in advancing or retiring the changeable hoes. Opposite to each of these' bars D a bolt, E, is arranged in the oscillating bar G, said bolts being intended to enter the perforations d in the bars D to lock the oscillating bar when the changeable hoes have been arranged in proper relation to the unchangeable ones.

The bolts are projected by spiral springs e, and are provided with laterally-projecting studs, e', Which extend, respectively, into eyes in the ends of the levers F and F. These levers turn upon the fulcrums f iand f1, and are pivoted together at f2, from which point the one marked F is bent downward, such bent end being linked to the arm or crank g of the swivel-bolt G, which is arranged in a pendant, G, fixed to the lower side of the oscillating bar C. Thefbolt G is fastened to tho rod H, which extends toward'the drivers seat v andterminates in a handle, H.

In shifting the changeable hoes, the operator first gives a partial rotation to the rod H, whereby the locking-bolts E are retracted and drawn out of the perforations in the bars D, and then pulls or pushes upon said rod to oscillate the bar G.

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

l. The combination ofthe Oscillating bar C, fixed perforated bars D, and locking-bolts E, substantially as and for the purpose specified.

2. The combination of theoscillating bar C, fixed perforated bars D, locking-bolts E, levers F F', cranked bolt G g, and rod H, substan tiall y as and for the purpose specied.

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

GEO. S. BALL.
