CHECK- ROWER.

SPECIFICATION forming part of Letters Patent No. 539,915, dated May as, 1895.

Application filed December 11, 1894. Serial No. 531,459. (No model.)

ure hereinafter described and it is defined in the appended claims.

In the drawings forming part of this specificatlon, Flgure 1 is a plan of check-row mechanism constructed in accordance with my invention. Fig. 2 is an elevation of the center movement of the check-rower from the position indicated'by arrow X, Fig. 1. Fig. 3 is a similar representation showing the connection between the check-rower and the shakebar disconnected. Fig.4 is an elevation of the front guide for the wire from the position indicated by arrow Y, Fig. 1. A seed box of a planter is shown at 1, a

shake bar at 2, a runner at3 and an end of a mtcmss bar of a planter at 1. The check row bracket 5 is shaped to fit the planter box, and it is secured thereto by bolt 6. Bar 7 is secured to the front end of the bracket and extended obliquely forward and outward. Bar 8 is fastened to the rear end of the bracket and extended rearward and inward. On the ex tended end of each bar is a forked lever 9 and a bracket 10 carrying guide pulleys 11 and 12,

' which will be described in detailhereinafter.

The vertical shaft 13 has bearings in bracket 5. It is supplied at its lower end with a hori-L zontally extended rockarm, 15, which may be connected with the shake bar 2 by means of rod 16, or in any other suitable manner.

The pin 22 extends transversely through the shaft and projects therefrom; and the shaft is held against longitudinal motion in its bearings. The rock plate let'is mounted loosely on the shaft above the cross pin, and a downward extending sleeve of the plate has A- shaped recesses adapted to receive the pin. The arm 17 is pivoted on the bracket at one end. It extends under the rock plate, and it has a hook, 18, that extends over the flange of the plate. Lever 19 is also pivoted on the bracket at one end and its opposite end is hooked downward in a manner and for a purpose to be hereinafter explained. Link 21 connects the lever 19 with the arm 17 and provides means for, using the lever to throw the rock plate in and out of clutch with the pin of the shaft. Rod 27 connects one end of the rock plate with the forward forked lever, and rod 28 connects the opposite end of the plate with the rear forked lever. The forward end of bar 7 is supported by brace 25, which is fastened to the barand to the front cross bar of the planter. The location of the planter seat, with relation to the check rower, is shown at 24:. The check row line 26 runs through the guide pulleys and the forked levers, as shown, and it is provided with knots by means of which thelevers are thrown and motion imparted t0 the planting mechanism.

The opposite side of the planter is supplied with check row mechanism the same as that shown and described, except that the arrange,- ment is reversed in order to carry the wire obliquely across the planter from the opposite direction. In other words, to use a com mon expression, the check row bars are rights and-lofts. I

As the planter moves forward a'knot on the the rear-forked lever and throws it backward to its shown position, and each operation imparts a dropping action to the planting mechanism."

While the check row line is used on one side of the planter the hooked-end 20 of lever 19, p

on that particular side, extends over the line in"a manner to hold it in the rower, and the clutch recess of the rock plate receives the cross pin of the shaft and completes the connection between the forked levers and the shake bar.

When an end of the field is reached the hooked lever, 19, is raised to the position shown in Fig. 3, thereby swinging it clear of the check row line and raising the rock plate.

from contact with the cross pin of the shaft; and subsequently the line is thrown off,.by detaching it from the rear guides by direct manipulation, and then raising it clearof the front forked lever and rear guide of thefrout pair of guides. This is done by the driver as he sits in his seat, that part of the line-adjacent to him being raised high enough to effect the desired result, and when the wire is clearof the rear guide of the front pair it will at once detachitself from the check rower. The planter may then be turned around, the line he placed I in the check rower on the opposite side of the planter, and the hooked lever on that side be swung downward over the wire, in, theman ner shown, and with the result that the rock plate on that side will be forced in clutch with the shaft that actuates the shake bar. This Will leave one side of the checkrower in en- As the front forked lever throws the rock plate in one direction and the throw of the rear forked lever reverses that direction, it will be seen that the plate may occupy either of two positions when the wire is thrownoff,

and that it is aneven chance whether or not the shake bar and the clutch member of the shaft will correspond tothe position of the rock shaft when the time foroperating the particular rock plate recurs.

If the parts should not properly coincide the inclined sides of the clutch recess of the rock plate will act on the pin to turn the shaft as the plate is forced down by the motiouof the hooked lever and will move the shake bar. to the position corresponding withithe forked levers of that particular side of the check rower; thereby making operative connection between the parts.

The manner of disconnectingithe line from the check rower, hereinbefore described, is; made possible partly by the oblique arrangement of the check rower and the provisionof two leversadapted to be successively actuated by the same knot, and partly by the construction and arrangement'of. the guides for the wire, particularly the front ones. The first named peculiarity brings the line and the rear guides in easy reach of the driver as he sits on his seat, and the last namedpeculiarity enables a simple raising of the wire, by the hand of the driver, to disconnect the wire from the front guards.

The guides 11 and12 are both shown and described herein as pulleys, and such is in fact the preferred construction; but it is not essential to a satisfactory operation of the device that guide 11 should rotate. The .essential features of this part of the device are that the front guide shall, rotate on an approximately vertical pivot and have an upper flange, and that the other guide, of the front pair. of guides, shall be flangeless at its'upper end. shal bevefli r ubstanti l y and helli a n a n a p ion'r vnih rear of the flanged pulley and outside the normal position of the check row wire. It is desirable, moreover, that the rear pair of guides be constructed as described and placed in reversed positions, as shown.

The forward pulley of the forward pair of guides-rotates to carry the wire, its flange holds the wire against upward displacement, and the rear guide of the pair holds the Wire against outward displacement. On the other hand, the rear guide of the front pair offers no resistance to the raising of the wire, in the manner specified, and when the Wire is once clear of Such guide t swings ree. o a

straint and is discharged from t. the check he hoo ed l e 19 i-d n etainins e wire in thecheck rower while the planteris. in operation, and it necessitates thedisen; gagement of the clutch mechanism prior to throwing oi the wire, thus; makingihcertai-n that itwill not be attempted-to run theplauter. with both check rowers in connection; with e ke ba y k g he c e k ower rasspeeifie e 'r w e may pas Over he e box, as shownin the drawings, and the open:
