CHECK-HEAD FOR PLANTERS.

Specification of Letters Patent. Patentd Sept, 13

Application filed July 18, 1917,Seria1 No. 181,384. Renewed December 3, 1920. Serial No. 428,151.

To all 'MZ om it may concern lie it known that T, liiimr .lyl. Bax'rnn, a citizen of the United States, residing at (Forydo-n, in the cminty of ayne and State oi Iowa, have inveutml certain new and useful Tinprovcments in a ChecleHead for Planters, of which the following is a specification.

This invention has relation to check row corn planters, and has for an object to improve the check headin a manner to permit the check wircto be more quickly and conveniently threaded thereinto, thereby providin what may be termed a sellithreading check head.

In addition to the foregoing my invention comprehends improvements in the details of construction and arrangement of the parts to be hereinafter more fully doscrihed and particularly set forthinthe appended claims.

In the ac( :om1 )anyin;r drawings in which similar and corresponding parts are designated by the same characters of reference throughout the several views inwhich they appear; 1 a

Figure 1. is a viewin side elevation of the right hand clicekheadof a check row corn planter illustrating the embodiment therein of my invention. a

Fig. 2,,is a view of the check head in end elevation, i i

Fig. 3, is a View thereof in plan.

W'ith reference to the drawings, 10 indicates a pair of parallel spaced bars which extcml transversely ofthe corn planter and whir support the seed boxes andthe check head indicatedas an entii'etyat 11. i The check head comprises a a frame casting formed with upwardly diverging curved arms 12. connected at their lower end by means of a connecting strip13 which is enlarged as at 14 to provide a journal for the seed dropper shaft 15. The shaft is dismachine, parallel to the bar 10. and has fixedly mounted thereon an upwardly extending arm 16 which is hifurcat .l at its upper end to receive a fork 17 which i s mounted upon a. bolt 18 extended across the bifurcated portion; of the said arm whereby to. permit oscillatory movement of said fork in aplane which is parallel to and intersects the seed dropping shaft. As will. be seen the fork may be dis posed in a horizontal position when inoperas tive and in a vertical position when operative.

The upper terminals oi. the arms 12 of the check head casting are formed with concaved extensions 19 which are located so as to direct their coneavcd portion outwardly to receive and g'i'lide the check wire. A pulley 20 mounted adjacent each of said concaved extensions to coact with said exten sion in such a manner as to retain the check wire therein in the usual manner. The pulleys 20 are mounted upon a. casting 21 in the nature of a yoke upon the terminals of which the pulleys are mounted, and which. yoke is provided with a pair of trunnions extending in opposite directions to fit in apertured cars 23 formed upon'the upper terminals oi the arms 12 ot the cheek head casting. Thus, the pulley holder is mounted for oscillation in a vertical plane from a position wherein the pulleys are located as described or for rotation in a horizontal plane, to a position wherein the pulleys are inverted from their former positions'. The object of mounting" the pulleys for movement in this manner is to open the concaved extensions 19 that the check wire may he inserted therein, the pulleys being sul'isequently moved to a position to inclose the wire in said. concaved extension and to securely retain the wire against dis placement. To retain. the pulley holder in its first mentioned position a latch 24: is pro vided. pivotally mounted as at 25 upon a gear 26 formed upon the check head casting for ei igagring the ii'itermediate portion of the pulley holder. the latch being held in such position by means of a spring 27 which is interposed between an extension 28 of the latch and the check head casting. The latch may be readily disengaged by means 01": a rod 29 which extends from said latch to apoint adjacent the drivers seat. a a

In order to guide and support that part of the wire which is adjacent the planter while it is bcinp; moved (bodily, laterally; under tension) from or toward the machine I provide a guide extending laterally outward from the check head or frame. This ,g uidingi and supporting device comprises av lower clement, indicated as an entirety by 31., and an upper element- 30. The upper element. comprises a bar 34L extending from transverm: Vertical planes in. front oil to transverse vertical planes in rear of those of the fork. It is stationary relatively to the frame, to which it is secured rigidly by attaching devices, such as arms (integral with the part 34 at the bends 32). with downwardly turned legs fastened to the check head. The front and rear bars. or attaching parts 35, are'bent as at 37 so as to providei'nclined parts 35 which are extenddevices at 41.

verse vertical planes of the fork and is stationary relatively to the frame. It is attached thereto by arms 40 (integral with bar 39) terminating in vertical legs which are secured to the check head or frame by the The arms 40 are, at e12. bent so that their outer parts 4:0 eXt-endydownward; outward and longitudinally of the machine. there being bends at 38 at the ends 7 of the bar 39. The inner parts 40* of the lower element are positioned horizontally.

The bends at 3'7 and42 are in approximately the same vertical longitudinal planes.

The outer parts of. the lower member and of the upper member .of the guide 'and support device diverge outward from the vertical plane of the bends and also diverge inward, when observed on horizontal lines longitudinal of the machine. The bars and 39 are both approximately parallel to said longitudinal lines but the bar 3% is positioned, laterally, away'from the frame con siderably farther than is the lower bar 39. A passageway for a relatively long section of the wire is thus provided through which it canbe moved bodily laterally in either direction, its passage having an inwardly narrowing entrance way (between the outer parts of the guide elements). extending to the bends 37, 42 and an inwardly widening partextending from the throat of the bends toward the frame. 'The fork 17 is formed of a pair of spaced parallel bars 43 which are bent away from each other to form the arms 43 and i3, and it will be seen from Fig. 2 that when the fork is disposed in a horizontal or inoperative position. the diverging portions of said fork lie substantially par-. allel to the diverging outer ends of the guides 30 and 31, so that any object such as a wire which is caused to enter laterally between the guide elements 30 and 31 will also be compelled to pass between the diverging ends of said members L3 of the fork so as to enter said fork.

When using a planter having my improvements the dropping of the wire at the end of a row is accomplished quickly and in substantially the same way that is now followed in using standard machines provided with check heads. such as are herein shown. Thatis to say, the operator by means of the usual cord and while in his seat. opens the catch Ql and releases the swinging parts of the wire holding system. the rollers :20 and their carrier 21. Under the tension of the wire these swinging parts are carried from the positions shown in Figs. l and 3 to that shown in Fig. 2. the fork 17 also being carried downward and outward by the downward and laterally moving. tcnsioned wire. The wire after escaping from the pulleys :20 impinges on the lower element of the guide and holder and is shed from the inclined outer part'and from its seatin the fork. over the bar 39, to the ground.

After the operator has turned the machine and is ready for the return traverse across the field it is then necessary to move the check wire and its ground stake from its old location to the. new location and to rcstore the wire to its normal working position in the holder provided for it by the parts on the check head or frame.

\Vith my mechanism it is not necessary for the operator to approach the check head to place the wire in operative position or is it necessary for him to resume his seat and then by foot operated or manual devices place the wire in position. All that is required is that after pulling the check wire stake from its old location in the ground the operator. as he moves the check wire and the stake toward the new location at which the stake is to be reset (which is directly in the rear of the middle of the planter). should hold the check wire in such position that it will enter the passageway formed between the uppe and lower guides 30 and 3 respectively, as he passes back of the check head. Then as the point is reached where the stake is to be reset the operator with the exertion of a quick longitudinal pull on the check wirc gives itthe proper tension preliminary to setting the ground stake. The longitudinal pull causes the. wire to complete its travel inwardly through the guiding means 30 and 31, and the wire in its inward movement carries with it the check fork 17 and the pulleys .20, they, as shown. lying in the path that the wire is constrained to follow.

When the check wire moves inwardly in response to the tcnsiouing impulse above described it follows the parts -35" and 35" of the upper guide (in some cases resting more or less on the support parts i and id). The check fork 17 is caused to swing upward around its pivot under the inward lateral pressure of the wire and the carrier bar 21 is also caused to rock upwardly owing to its engagement with the arm 412-3" of the fork. or if preferred, the parts can be arranged for llll the cheek wire to impinge upon the pulleys 20 or the carrier bar 21 and rock them into closed position. The quick inward lateral pressure of the wire due to the longitudinal pull acts upon" the fork 17 and the pulleys 20 (upon the latter through the pulley bar 21) to snap them into the position shown. in Figs. 1 and 3 where they are locked by the catch 24 engaging the bar under the action of spring 27.

All of these matters have been accomplished without any movements of the guide elements 30, 31. reh'itively to the frame, both the lower and the upper element ren'iaining fixed in position. The wire through the force of tension exerted upon it has causelfl all of the movements of the parts from the positions of wire discharge to their normal working positions, and has caused an automatic locking of these parts in the latter po sitions.

If at any tune it is desired to use the planter with the ordniary parts, the bolts or fasteners 36 and 41 which attach the check wire holder and guide can be readily removed and the guide taken off, the remaining parts then constituting a complete operative holder and guide of the standard sort. a To persons acquainted with the use and operation. of checkrow corn planters, the saving of time and labor may be effected by the use of this improvement, will be immediately apparent.

\Vhile I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations thereover may be made. and I therefore desire to reserve the right and privilege of changing the form of the'details of construction, and of altering the arrimgement of the correlative parts without departing from the spirit of the invention or the scope of the appended claims.
