URIAS SIIAEFFER, OF LANCASTER, OHIO.

CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 644,780, dated March 6, 1900.

Application filed August '7, 1899.

To tel]. whom, it may concern:

Be it known that I, URIAs SHAEFFER, a citizen of the United States, residing at Lancaster, in the county of Fairfield and State of Ohio, have invented a certain new and useful Improvement in Corn-Planters, of which the following is a specification.

My invention relates to the improvement of hand corn-planters, and has particular relation to the improvement of that portion of the planter which is known as the seed cut-off.

The objects of myinvention are to provide an improved cut-off of this class which will be simple and inexpensive of construction and which at the same time will be durable and effective when in use and to provide other improvements in details of construction and arrangement of parts, which will be more fully pointed out hereinafter. These objects I aocomplish in the manner illustrated in the accompanying drawings, in which- Figure 1 is a view in perspective, showing the character of hand corn-planter to which my invention applies. Fig. 2 is an under side view of the seed-cut-olfframe and cut-off therein. Fig. 3 is a detail view in perspectiveof a portion of one of the planter-legs, showing the seed. disk mounted upon a bracket-casting projecting from said legs at the usual point. Fig. 4 is a detail view in perspective of the cut-off frame-ri-n g, showing my improved cut-off therein. Fig. 5 is a detail view in perspective of'a portion of the cut-01f ring and cut-off, and Fig. 6 is a detail view in perspective of the cut-off.

Similar numerals refer to similar parts throughout the several views.

land 2 respectively represent the usual jointedlyconnected legs of a hand. cornplanter, the leg 2 being provided with a projecting casting or bracket 3, on which is retatably mounted a desirable form of seed-disk 4, the latter receiving its intermittent rotary motion through the engagement therewith of operating-arms 5, which are connected with the leg 1. The feed-disk 4 is provided in the usual manner with the desired number of eccentrically-arranged feed-openings 6, which are designed by rotation of said disk to register successively with a feed-opening in the casting 3. This construction and operation,

Serial No.726,361. (No model.)

however, is clearly set forth in my former patent, No. 571,935, dated November 24, 1896.

7 represents the cylindrical hopper, which, asset forth in said former patent, is secured to the forward leg 2 and has its otherwiseopen lower end provided with a cut-off frame ring 8, the latter being supported immediately above the feed-disk 4.

In constructing the frame-ring 8, which is substantially of a D shape, I cause the same to be intersected by a cross-arm or web 9, the

latter being formed on one side with an upwardly-projecting pocket portion 10, through the upper side of which is formed a small opening 11. i

12 and 12 respectively represent oppositelylocated bearing notches or recesses, which are formed, respectively, in the under side of thering-frame or web 9 and the corresponding side of the inner portion of the ring 8.

14 represents my improved cut-off, which, as indicated in the drawings, is in the nature of .a metallic casting,theinnerend portion of which turns upward and thence outward in the direction of the length of the casting, the horizontal termination 15 thereof being recessed centrally, as indicated at .16, and provided on opposite sides of said recess with downwardly-projecting lugs 17. At a point near the center of the length of the casting 14 Iprovide oppositely-located and laterallyprojecting trunnions 18, which, as indicated in the drawings, are adapted to bear within the oppositely-located recesses 12 of the ring 8. The outer end portion of the cut-off 14 is provided with a downturned and inclined shoulder or tooth 19. For reasons hereinafter set forth the under side of the cut-off is so formed as to present no sharp angles, and the upwardly'projecting portion of said cut off is, as indicated at 20, preferably rounded or concaved on its inner face. In order to provide a spring-actuated connection of the seed cut-off with the ring 8, I employ acoiled spiral spring 21, the upper and larger end. of which embraces the projectinglugs 17 of the cut-off, While an extension of the wire which forms the spring passes upward through the spring,'from the tapering end of the latter through the slotted opening or recess 16 of the contact with the surface of the disk.

the ring-frame pocket, where it is looped, as indicated at 12, to prevent its return through said opening. In this manner the cut-off is actuated by a spring and its downturned tion 15 of the out off will contact in case the latter is tipped an undesirable distance.

From the construction herein shown and described it will readily be seen that a simple and inexpensive form of cut-off and supporting-ring is provided, and that being formed of metal the same will be exceedingly durable. It will also be observed that in the manner described the coiled spring is made to serve both the purposes of hinging the out off to the ring-frame and of retaining the lip or shoulder portion 19 in desirable frictional Owing to the fact that the under side surface of the cut-off presents no sharp angles or corners it will be seen that the tendency toward the grain sticking orlodging thereon is obviated.

In case it is desired to remove the cut-off it is evident that the same may be so manipulated as to admit of its withdrawal from beneath the spring and disconnection of the latter without the removal of said spring.

I am aware that metallic cut-offs have been employed heretofore in other classes of cornplanters and that the same have been actuated by a coiled spring; but such construction differs from that herein set forth and claimed.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a corn-planter, the combination with a planter-frame, a perforated rotating disk mounted thereon, of a hopper mounted above said-disk, a ring-frame in said hopper, a metallic cut-off fulcrumed in said frame and having an end recess 16 and a coiled {spring having an extension at one end which passes through said end recess and engages the ringframe and having its remaining end bearing on the inner end portion of said cut-off and retaining the latter in place, substantially as and for the purpose specified.

2. In a corn-planter cut-off, the combination with a frame-ring 8 having a cross-arm or web provided with a pocket or depression, of a metallic cutoff fulcrumed in said ring and having a projecting portion adapted to bear in said ring-pocket, said cut-off being provided with a downturned lip portion 19 and a coiled spring, the upper portion of which retains the cut-off in hinged connection with the ring and the extension of the lower end of which passes through said coil and engages said ring cross-arm, substantially as and for the purpose specified.
