A TTOR/VE V EDWARD J. GRUIBEN, OF ROYSTON, TEXAS.

PLANTER.

Specification of Letters Patent.

Patented J an. 16, 1917.

Application filed April 4-, 1916. Serial No. 88,916.

To all whom it may concern Be it known that I, EDWARD J. GRUBEN,

a citizen of the United States, residing at Royston, in the county of Fisher and State of Texas, have invented certain new and useful Improvements in Planters, of which the following is a specification.

This invention pertains to new and useful improvements in planters.

Various means and methods have been evolved and used for planting straight rows, but require more or less preparatory or mechanical work in every case.

It is the purpose of my invention to provide a planter by which the grain may be planted in a straight row and in which the foot or shovel may be guided by a swaying movement of the driver.

In carrying out the invention the mast on which the foot or shovel is carried is mounted in a roller guide frame and constructed to easily rotate. A swinging seat member is mounted on the frame and connected with the mast so that when the seat is swung to one side the mast will be rotated and the point of the shovel moved in the desired direction.

In planters now in common use the constructlon is invariably such that the elevating or plow raising lever is raised when the plow is lowered, said lever being constantly in the way of the driver. My invention also contemplates a construction whereby this lever is lowered to lower the plow or shovel and remains in a horizontal position during the planting operation.

Other objects will be apparent from a perusal of the following specification and the invention will be more readily understood by reference to the accompanying drawings, wherein:

Figure 1 is a plan View of a planter equipped with my invention, Fig. 2 is a side elevation of the same, certain parts being omitted and others indicated as broken away to show component parts, and Fig. 3 is a detail of the roller guide frame and'adjusting means for the mast.

In the drawings the numeral 1 designates a horizontal frame attached to a tongue 2 at its forward end and carrying a cross-bar support 3 at its rear end; while similar sup ports 4: and 5 respectively, are disposed forward and rearward of the aXle 6. The forward support 5 is enlarged at its center to permit a vertical mast 7 to pass therethrough. This mast carries the usual shovel or plow 8 at its lower end and is shown in Fi 2 in its raised position.

tandards 9 secured to the cross bar 5 support vertical shafts 10 carrying rollers 11 on their upper ends and rollers 12 on their lower ends. The lower rollers 12 rest on the cross-bar 5. These rollers of which four upper and four lower are shown, bear against the mast at equidistant points. The mast being cylindrical may be easily rotated, the rollers reducing the friction to a minimum. By observing Fig. 2 it will be seen that a slight partial rotation of the mast will swing the point of the shovel to either side of the center of the planter according to the direction of rotation of the mast.

For rotating the mast the seat 13 is arranged to swing. The seat is mounted on the upper end of a rearwardly inclined seat bar 1i having its lower end pivoted on the bar 4. An angular arm 15 depends from the seat bar and has a roller 16 mounted on its lower end. This roller travels on the bar 3 which has an arcuate portion forming a track for said roller. A connecting bar 17 is centrally pivoted on a bolt 18 passing through the seat and seat bar. This bar 17 extends transversely of the frame and has its outer end pivoted to the rear end of parallel lengths 19 extending forward and pivoted on vertical rods 20 fastened be tween arms 21 projecting laterally from the mast. As indicated by the dotted line in Fig. l the mast is rotated and the parts angularly displaced when the seat is swung to one side; the swinging movement of the seat being communicated to the mast through the agency of the parts 17 19, 20 and 21.

It is pointed out that the slightest lateral adjustment of the plow point 8 will cause the wheels and the whole frame to immediately follow; thus the seed tube will drop seed in the furrow and in the proper place.

A yoke 22 supports the links and is provided with a central depending shank 23 which is fastened to the rear standard 9. This yoke permits the links to be swung and supports them at the same elevation irrespective of the adjustment of the mast, the rods being free to slide through the ends of the links. A cap 24 is mounted on the upper end of the mast and rests on a collar 25 clamped about the said mast and having forwardly projecting cars 26. The upper arms 21 are mounted on the mast. A vertical link 27 has its upper end pivoted between the ears and its lower end pivoted in a crank arm 28 projecting rearwardly from a rock shaft 29 mounted on the frame and having one end supported in a segment bracket 30 which cooperates with an elevating lever 31 fastened on the shaft. This lever has a spring pressed locking plunger 32 engaging the bracket 30. The lever is made to serve the double purpose of elevating the mast and shifting the clutch of the seed dropping mechanism and with the shovel elevated and the dropping mechanism unclutched, the lever occupies an angular position of about. forty-five degrees to the perpendicular. The usual clutch sleeve 33 is mounted on theaXle 6 to engage with mechanism (not shown) mounted under the seed can 34: and forming no particular part of this invention.

A clutch lever 35 is pivoted on an arm 36 projecting inward from the frame 1 and has its rear end attached to a coiled spring 37 which is also fastened to the frame. The forward end of the lever is forked and embraces the sleeve 33 to which it is pivoted in the usual manner. The forked end of the lever is connected with the end of a chain 38 which passes over a pulley 39 mounted in a. bracket 40 projecting from the framenear the said end of the lever. The chain extends upward and is attached to the lever 31 as shown.

It is apparent that when the lever is swung downward the chain is slackened whereby the spring 37 swings the lever 35 and shifts the clutch sleeve 33 into engagement with the dropping mechanism; while at the same time the shaft 29 is rocked so that the arm 28 is swung downward whereb the link 27 is carried downward which results in the lowering of the mast and the opener attached to said mast, a seed dropping clutch mechanism, an adjusting lever having connection with the mast foradjusting the same and also connected with the clutch mechanism for shifting the same, and means for rotating the mast.

3. In a planter, a vertical mast, a furrow opener attached to said mast, a roller guide frame in which the mast is both rotatable and slidable vertically, a swinging seat, and a rotating structure connected with the seat and also with the mast for rotating the latter, said structure being supported in a fixed horizontal position, the mast being slidably connected therewit 4. In a planter the combination of a frame, a guide frame mounted on the frame and having a plurality of rollers, a cylindrical mast passing through the guide frame and engaging the rollers, a furrow opener attached to said mast, means for vertically adjusting the mast, a swinging seat mounted on the frame, a roller support for the seat, a track mounted on the frame and supporting said roller support, a pair of forwardly extending links pivotally connected with the seat, lateral members carried by the mast for. rotating the same, and connections slidably engaged by the links and attached to the lateral members.

In testimony whereof I affix my signature.

EDWARD J. GRUBEN.
