IMPROVEMENT lNSEEDlNG-MACHINES.

Specification forming part of Letters Patent N0. 157,166, dated November 24, 1874 application filed February 12, 1874.

To all whom it may concern;

Be it known that I, AUSTIN O. EVANS, of Springfield, in the county of Clarke and State of Ohio, have invented a new and useful Improvement in Corn-Planters; and Ido hereby declare that the following is a full, clear, and exact description of the same, in which- Figure 1 is a top or plan view. Fig. 2 is a side elevation, partly in section. Fig. 3 is a vertical longitudinal section of the dropping mechanism. Fig. is a bottom view of the feed-plate. Fig. 5 is a plan of the feed-plate of the second dropper. Fig. 6 is a section of the feed-plate.

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

Letters. Patent were recently issued to me for an improved corn-planter; and it is upon that machine that the improvements now the subject of application are more particularly intended to be applied, though they are capable of application to other analogous machines. The nature of these improvements will be distinctly indicated in the following specification and claim.

A is the frame, made of two pieces of 'wood, bent as shown, the clevis being attached to the front end, where they are united. B is a vertically-adjustable wheel, fastened to the front end of the frame. The rear end is supported on the covering-wheel 0. The seed is supplied from a hopper, 1), on the frame, having a feed-wheel, E, in the bottom, per- 7 forated with holes E, in which the grains are carried, one by one, to the spout L. On the bottom of the wheel E are a series of pins or teeth, E, arranged to receive the thread of the endless screw F, revolving with the shaft F and rotating the feed-wheel E. This shaft derives motion from a bevel-pinion, F meshing into teeth on the side of the coveringwheel 0. (Shown'at C The end of the shaft F runs in a box, G, attached, by a stem, G, to the lever H, which is pivoted to the plow-handles in such position that the operator may conveniently reach it when he desires to throw the pinion F into or out of gear with the covering-wheel. The axle of the wheel 0 rests in a bracket, I, which also serves as a guide and support for the stem G.

In order to prevent the grains from passing over the spout by lodging in the holes E of the feed-plate E, and clogging the action of the machine by jamming against the lower edge of the hopper, I place a thin piece of metal, K, on the back of the hopper and immediately over the pipe L, which is intended to conduct the grain from the feed-plate E. This plateK is set with its edge close to the wheel E, so that if any grains should project above the surface of the feeding-plate, they will be pushed down or sheared off.

In the bottom of the pipe L is the piece M, which, when the machine is used for drilling, remains open, so that the grains may pass downward without interruption. But if the corn is to be planted in squares, then it may be used to retain the grains of corn until they are dropped by the operator at the proper intervals. This is accomplished by the following-described mechanism: The piece M, which is sustained by the hoe P, is recessed to receive a cut-off slide, N, which is formed with a central hole for the passage of the grain, and two pins, (shown in Fig. 3,) which are received in theislots in the front and rear of piece 'M. (Clearly shown in Fig. 5, which is a bottom view of the same.) The slide N is actuated by a vertical lever, 0, connected, by a rod, 0 with the thumb -latch 0 This latter is pivoted to the handle, and so weighted upon the lower end that it will normally maintain the slide N in such position as to leave the opening from the tube L open but when the operator presses his thumb I do not claim any of the parts of the magravitating thumb-latch 0 all substantially chine broadly, as being new in themselves; as and for the purpose specified.

but In testimony whereof I have signed my name What I claim as my invention, and desire to this specificationin the presence of two subto secure by Letters Patent, is scribing witnesses.

In combination with the recessed, double- AUSTIN O. EVANS. slotted, and perforated piece M and cut-off W itnesses: slide N, constructed with projections to engage H. S. SHOWERS,

said slots, the lever O, connecting-rod 0 and F. O. RUNYAN.
