HAND CORNPLANTER.-

SPECIFICATION forming part of Letters Patent No. 427,625, dated May 13, 1890.

Application iiled February 13,1890. Serial No. 340,352. (No model.)

To all wil/0m it may concern:

Be it known that I, JOSEPH M. SEGUR, a citizen of the United States, residing at Adrian, county of Lenawee, State of Michigan, have invented a certain new and useful Improvement in Hand Corn-Planters; and I decl-are the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

In the drawings, Figure l is a front elevation of the corn-planter embodying my invention. Fig. 2 is a longitudinal central sec- Fig. 3 is a separate view illustrating how the door is hinged to the top of the hopper. Fig. 4 is a cross-sec tional view through the stop-plate. Fig. 5 is an enlarged view showing the relative position of the seed-cup and its cut-off when the plunger is at the top of its stroke. Fig. 6 is an enlarged front view of the cut-off and its spring.

It is the purpose of my invention to produce a hand corn-planter which shall possess certain novel features of construction; and it consists, lirst, in novel and convenient means for hin ging the lid to the top of the `hoppe 5 second, in novel and eflicientmeans for limiting the upward and downwardv stroke of the plunger; third, in a novel spring arrangement whereby the seed cut-oft is poised in its place, so that it may yield freely in a direction from side to side and longitudinally of the cut-off, while at the same time it may be pressed outward or yield to the pressure of the grain from within the seedcup.

In carrying out myinvention, A represents.

the standard, and B the seed-hopper, of the planter embodying my invention.

C represents the plunger; D, the plungerrods; E, the seedscup; F, the cutoff, and Ii" the cut-off spring.

At the top of the. hopper B is a lid B', hinged to turn outward about its outer edge.

In order to form a suitable hinge-rod, I employ a wire l), which is bent at its extremities to form arms h', and at the ends of these arms they are bent outwardly or inwardly, as shown at b2, whereby the said hin ge-rod is held iirml y in its place .by the bent end coming against the metal of the hopper. The nipple at the top of the' hopper is turned over this wire, which gives to the hopper at this point the requisite strength and finish.v This construction affords a ready means for hinging the lid, which is very effectual and makes a cheap and durable construction.

CZ represents the bends or kinks in the plunger-rods D, and D represents the stopplate, which is held in place by one or more bolts or fastenings d', which unite it with the standard. This plate and the bends d are so disposed with relation to each other that as the plunger is moved up or down these bends or kinks, coming into contact with the plate, will limit the motion of the plunger in either direction. This forms .a very effectual stop contrivancc for limiting the throw of the plunger.

The cutoff spring F is constructed as shown in the drawings. gated forn1-tliat is to say, it is bent upon itself two or more times between its middle and each extremity.

As shown at f, the extremities are united by screws or otherwise to the standard. The spring lies flat across the standard and the top of the cut-off F, and the cutoff is fastened to the middle loop or corrugation of the spring by a screw or bolt and washer f. Now, it is apparent that this seed-cup may be adjusted longitudinally with respect to the spring by simply loosening the said holt or screw f. This spring F', constructed as above described, has a very peculiar action. Its middle portion is flexible in all directions-that is to say, it permits the cut-off to vibrate, if necessary, in a longitudinal direction, and also permits it to.. vibrate lat cra-ily if it should be so impellcd, while at the same time any pressure of grain from beneath will lift its upper end, so as not to crush the grain, and this is accomplished by reason of there being at least two or more corrugations or folds in the wire between the middle and each extremity of the spring. Two complete loops upon each side of the middle one are sufficient for the usual purposes; but if it is desired to be adj usted still more sensitively an additional loop may he employed on each side, or more loops, it necessary.

It is made in corru- IOO y completely empty the seed-cup, causing it to descend with a portion only or none of its charge. I overcome this difficulty as follows: I adjust the throw of the plungerwith respect to the seed-cup and its cut-oft' so that when they seed-cup is at its uppermost point it will have only partially passed upward by the 1 cutoff, leaving the cut-off at such a point as topartially close the seed-cup, but at the same time leaving enough opening into the seed-cup above the cut-off to permit thecorn or seed to easily enterandfill the cup. Now, when thev plunger descends, the only kernels or grains that can by any possibility become clogged with the eut-off will be those close at the topk of the seed-cup, and should any such kernel bel expelled by the cut-off it cannotre sultin carrying out the other grains from the seed-cup. This arrangement insures that each descent of the plunger will carry substantially a full charge of seed in the seed-cup.

The spring arranged to admit of longitudinal and lateral as well as outward vibrations of the cut-off greatly assists to prevent ita wire extending across said outer edge,

thence backward along each side of the hopper, and with its extremities turned through fthe metal of the hopper to hold it in place,

. with plunger-rods D, of'bends or shoulders d and a stop-plate D', fastened to the standard and with its ends engaging said plunger-rods,

:substantially 'as and for the purposes described.

3. In a hand corirplanter, the combination, with its cut-off, of a flat corrugated spring F',

, said spring fastened at its middle to the cutoit and at its extremities to the standard or adjacent parts, and having two or more loops of its corrugations interposed between the middle and each extremity of the spring, substantially as and for the purposes described.

4. In a handcorn-planter, the seed-eupvand cut-off and means for actuating the seed-cup,

the travel of said seed-cup being s0 adjusted with respect to the eut-oit that at the'uppermost point of its travel the` cut-olf shall remain partly over the seed-cup, substantially as and for the purposes described.

5. In a hand corn-planter, the combination, with a seed-cup and means for actuating the same, of a yielding cutoff arranged in such position with respect to the seed-cup that it shall partly cover the seed-cup when the lat ter is at the top of its stroke, substantially as and for the purposes described.

6. The combination, with a hand cornlplanter, of a cut-olf poised in position by a `spring to which it is attached,` said spring adapted to permit vibrations longitudinally and laterally ot' the cut-off and to yield outwardly to a pressure of seed from within, substantially as and for'thc purposes described.

In testimony whereof I sign this specification in the presence of two witnesses.

JOSEPH M. SEGUR.
