I V MARKING ATTACHMENT-FOR CORN-PLANTERS.

To all whom it may concern:

Be it known that I, Omvnu SMITH, a citizen of the United States, residing at Sully, in the county of Jasper, Stateof Iowa, have invented certain new and useful Improvements in Marking Attachments for Corn- Planters; and I do hereby declare the follow .ing to be a full, clear. and exact description of the invention, such as will enable others skilled in the art to which it appertains to makeand use the same.

The present invention relates to improvements in marking attachments for corn planters, and it has for its primary object the provision of an extremely simple and effective device of that nature which maybe readily attached to the frame of a corn-planter of any ordinary type, may be swung to either side of the machine by means of a foot lever, thus leaving the hands of the driver free, and which will be positively guided and held against displacement during its swingmg movements.

More especially, the invention resides in the specific construction of the staff of the marker, in the particular manner inwhich the marker is mounted with reference to the frame of the machine, and to the guides carried thereby, in the particular mechanism employed for effecting the swinging movement of the marker, and in the particular manner in which the latter is connected with such mechanism.

The preferred embodiment of the invention is illustrated in the accompanying drawings, in which corresponding parts or features, as the'case may be, are designated by the same reference numerals throughout the several views, wherein:

Figure 1 is a plan View of the complete invention, showing the marker lowered. Figs. 2 and 3 are respectively, transverse and longitudinal sections taken on the lines 22 and 3-3 of Fig. 1. Figs. 4 and 5 are detail views, respectively, of the marker and of the crank lever by which it is operated. Fig. 6 is a side elevation of the invertion, showing the marker in upright position. Fig. 7 is an enlarged detail view of the bracket in which the lever and drive shaft are journaled.

Referring more particularly to the draw ings, 5 designates the frame of the corn planter, which latter may be of any ordinary type now in use, the longitudinal sills of said frame being provided intermediate their ends with bracket hearings in which the axle Specification of'Iietters Patent.

sills are connected together by a cross-beam S, and at their rear ends by a pair of parallel cross-beams 9 and 10 arranged in spaced relation to each other, the portions of each sill between the last mentioned beams and directly in front of the beam 9 being bent downwardly to form the seats 11 shown in Figs. 3 and 6.

Upon each of the beams 9 and 10 is mounted an upstanding metal arch l2, which, in consequence of the above-described arrangement of said beams, are likewise disposed in spaced relation to and parallel with .each

The rear beam 10 has set into its inner side face, intermediate the ends thereof, a horizontal pin 13 to which the marker rod 14 is pivoted at its inner end, said rod carrying at its outer end a revoluble marking disk 15. The marker, as a whole, is thus capable of a swinging movement in a vertical plane between the arches 12, which thus not. only serve to guide the marker during such movements, but also to hold it against lateral displacement, the movement of the marker in either direction being limited by its contact with the corresponding seat 11, the height of the beam 10 and the depth of the seats being sufficient to permit the marking disk to contact with the ground when the marker rod finger 19 which, however, extends in the.0p-"

posite direction from the finger l7 and pro-.- jects through the lower of a pair of horizontal openings 20 and 21 formed in an upstanding bracket 22, mounted upon the beam 9, the fingers 17 and .19 being heldagainst displacement from the slot 16 and opening 21, respectively, by any preferred devices.

The finger 19 has rigidly secured thereto a gear 23, which meshes with a larger gear 24 carried by a shaft 25 which is disposed longitudinally of the frame of the machine and has its rear end projecting through the upper opening 20 in the bracket 22, while its front end is journaled in a bracket hearing secured to a cross beam 26 whose ends are fastened to the side sills of the frame, the extreme rear end of said shaft having secured. thereto a treadle 27. The treadle is arranged for opera- I tion by the feet of the occupant of the seat -When, therefore, either end of the treadle is depressed, the consequentrotation of the shaft 25 will be transmitted to the crank lever 18- through the gears 24 and 23, whereupon said lever, and with it the marker, will be swung in a vertical plane, the direction of movement of the lever and marker being opposite to the direction of rotation of the shaft 25. Thus, when'the right hand end of the treadle, with respect to Fig. 1, is depressed, the marker will be swung downwardly to the left and vice versa. It will thus beunderstood that the movements of the marker are controlled entirely by the treadle which is operated "by foot pressure,

the hands of the operator being thus left free.

During the progress of the machine and while the marker is not in use, it may be retained in vertical position by pressure upon both ends. of the treadle.

\Vhat is claimed is:

1. In a machine of the class described, the combination, with a pivoted marker, of a lever disposed parallel with the marker and provided at each end with a crank finger; one of said fingers being engaged with said marker; a gear secured to the other finger; a shaft disposed at ri 'ht angles to said lever; a gear-secured to said shaft in mesh with the first-mentionedgear; and means for rotating said shaft in either direction, to swing said lever and said marker in a vertical plane.

2. In a machine of the class described, the combination, with a pivoted marker pro vided intermediate its ends with a slot; of a lever pivoted at one end and provided at its other end with a crank finger engaged in the ,lot in the marker; a gear secured to the pivoted end of the lever; a shaft-disposed at right an les to said lever; a ear secured to said shaft in mesh with the first mentioned gear; and means for rotating said shaft in either direction, to swing said lever and said marker in a vertical lane.

3. In a machine of the class described, the

combination, with a pivoted marker provided intermediate its ends with a slot; of a lever pivoted at one end and provided at its other end with a crank finger engaged in the slot in the marker; a gear secured to the pivoted end of the lever; a shaft disposed at right angles to said lever; a gear secured to one end of the shaft in mesh with the firstmentioned gear: and a treadle secured to the other end of said shaft, for rotatin the same in either direction, to swing said over and said marker 111 a vertical plane.

4. In a maclnne of the class described, the

combination, with a frame including parallel side sills, of a pair of spaced upstanding arches arranged transversely of the frame and having their ends secured to said sills; a'marker pivoted at its inner end to the frame for movement in the space between said arches; a lever dis osed )arallel with the marker and providerl at eac 1 end with a crank finger; one of said fingers being engaged with said marker; a gear secured to the other fin er; a shaft disposed at right angles to said lover; a gear secured to said shaft in mesh with the first-mentioned gear; and means for rotatin said shaft in either direction, to swing said lever and said marker in a vertical plane.

5. In a machine of the class described, the combination, with a frame including parallel side sills, of a pairof spaced upstanding arches arranged transversely of the frame and having their ends secured to said sills; a marker pivoted at its inner end to the frame, for movement in the space between said arches, said lever being provided intermediate its ends with a slot; a lever pivoted at one end and provided at its other end with a crank finger enga ed in the slot in the marker; a gear secured to the pivoted end of the lever; a shaft disposed at right angles to said lover;

a gear secured to one end of the shaft in mesh with the first-mentioned gear; and a treadle secured to the other end of said shaft, for rotatin the same in either direction, to swing said Iever and said marker in a vertical lane.

In testimony whereof, I affix my signature, in presence of two witnesses.
