Specification of Letters Patent.

Patented July 21, 1908.

Application filed September 20, 1906. Serial No. 335,370.

To all whom it may concern:

Be it known that I, SAMUEL H. TINSMAN, a citizen of the United States of America, and resident of Fort Madison, Lee county, Iowa, have invented a certain new and useful Improvement in Planters, of which the following is a specification.

My invention relates to seed-planting machines of the type known as listers that is to say, planting machines in which a double mold board furrow-opener is combined with seed-dropping mechanism operated by the supporting wheels of the planter, and in which the corn or other seed is dropped in the furrow made by said furrow-opener as the planter is drawn over the field.

Generally stated, the object of my invention is the provision of an improved and highly efficient seed-planting machine of the so-called lister type.

Special objects are to provide an improved general construction; to provide improved means for operating the seed-dropping mechanism; to provide improved means for con trolling the seed-dropping mechanism when the planter is raised and lowered; to provide an improved arrangement in which the the forward wheels can be rocked to raise and lower the furrow opener in the frame; and to provide certain details and features of improvement and combinations tending to increase the general efliciency of a seed-planting machine of this particular character.

To the foregoing and other useful ends, my invention consists in matters hereinafter set forth and claimed.

In the accompanying drawings, Figure 1 is a side elevation of a lister embodying the principles of my invention, the near wheel eing removed for convenience of illustration,- Fig. 2 is a plan of the lister shown in Fig. 1,- Fig. 3 is a longitudinal section of said lister; Figs. 4 and 5'are details of the means for operating and controlling the seed-drop ping mechanism within the hopper; Fig. 6 is a view similar to Fig. 1, but showing the furrow-opener lowered to the ground; Fig. 7 is a detailed section on line 7-7 in Fig. 6. As thus illustrated, my improved lister comprises a double mold board furrowopener A, which is mounted upon a forward extending beam a. This beam is supported at its forward end by the upper portion of a bail-shaped axle B, and at its rear end by a swinging bail O. The said axle is supported in the hubs of wheels D. The said bail is supported in brackets c, which are secured to the body frame E. It will be seen that this body frame is U-shaped in form, having its rear end su ported by the double caster wheel F, whic latter is free to swing or caster from side to side. The said axle B is supported in bearings b secured to the forwardend portions of the said U-shaped frame. A spring G connects the rear crosspiece of said body frame with the said beam a of the furrow-opener, thus assisting in raising the latter from the ground. With the arrangement shown provision is made for attaching draft devices to the forward end of the said beam a. A clip H is fastened to the said beam and carries an ordinary sod cutter or colter I, which latter runs ahead of the double mold board furrow opener. The rotary covering disks J are secured to the rear ends of the two mold boards of the furrowopener, and arranged in position to assist in throwing the dirt over the seed dropped from the delivery spout K. It will be seen that this spout extends downwardly to the point just in the rear of the heel of the said rrow-opener. The double caster wheel F comprises two wheels which tend to push the dirt toward each other, thus assisting in covering the seed dropped by the planter.

A drivers seat L is suitably mounted and supported upon the rear portion of the U- shaped body frame. At its forward portion, the two ends of the U-shaped frame are connected through the medium of two uprights M and a bearing or casting m, as shown more fully in Fig. 5. This, in effect, provides an arch at the forward end of the body frame, and upon this arch is mounted the hopper N which contains the seed-dropping mechanism of any suitable known or approved type. The said seed-dropping mechanism is operated by a horizontal shaft m supported in said bearing m and provided with a bevel gear m which engages the rotary plate m on the bottom of the said hopper. A sprocket wheel m is secured to the other end of said shaft and a spring m is supported between the said sprocket wheel and a bracket arm m which extends around from the casting m. A collar m is keyed or otherwise secured to said shaft, and a slotted link or arm 0 is inter posed between the said collar and the said portion m. It will be observed that the slot 0 in said link or arm permits the latter to move up and down upon the said shaft. It will also be seen that the cam portion 0 on the said link or arm will engage the collar of and cause the bevel gear m to disengage from the rotary plate m when the said link or arm 0 is moved upwardly. At its lower end the said link or arm is pivotally con nected with one arm or vertically swinging portion of the bail-shaped axle, as, for example, by 'means of a clamp or bracket 0 secured to said axle (see Fig. 6). A sprocket wheel P is secured to a sleeve on said axle, which sleeve engages or connects with the adjacent supporting wheel D, whereby the said sprocket wheel rotates when the planter is traveling along. A s rocket chain Q connects the sprocket whee P with the sprocket wheel m, as shown more clearly in Fig. 6, and with this arrangement the rotation of the wheel D is accompanied by the rotation of the shaft m If the bevel gear m is in engagement with the seed-dropping mechanism, the latter is then operated. hand, if the furrow-opener is raised from the ground, and the axle B thus swung into the position shown in Fig. 1, it is obvious that the seeddropping mechanism is thereby rendered inoperative, by reason of the endwise shifting of the shaft m. When the furrow-opener is down, as shown in Fig. 6, the cam portion 0 then disengages from the collar m permitting the shaft m to shift endwise under the pressure of the spring m causing the bevel gear m to rengage the mechanism of the seed-dropping devices at the bottom of the hopper. When this is done, the seed-dropping mechanism is operated, and the seed discharged from the hopper is conducted through a pipe or hollow connection It to the spout and then dropped in the furrow made by the furrowopener A. The seed is then covered up, or partially so, in a manner previously described, and according to the adjustment of the disks J and the wheels F.

A hand lever S is secured to one spindle or end portion of the axle, and is provided with locking means ada ted to engage the tooth locking rack T, w ich latter, of course, is rigidly secured to the frame E. With this arrangement the driver can rock the shaft and thereby raise and lower the furrowopener, and at the same time automatically control the connections between the Wheel and the dropping mechanism. It will be seen that the spindles of the axle, and the axis about which the wheels rotate, are lo cated substantially above the point or toe of the furrow-opener, thus facilitating the turning around of the planter.

It will be seen that the covering disks J are provided with pivoted bearings On the other by these disks can be adjusted about vertical axes, so as to vary the angle of each disk according to requirements.

What I claim as my invention is ping mechanism, an endwise movable shaft provided with means for engaging said mechanism, means for automatically shifting said shaft endwise when the furrow opener is raised and lowered, a wheeled frame supporting said mechanism and furrow opener, and means for raising and lowering said furrow opener without raising or lowering said shaft and mechanism.
