fiPECIPICATIOI-I forming part of Letters Application filed March 21, 18st Z0 all whom it may concern:

Be itknown that I. Lnwrs E. WATERMAN, a citizen of the United States, residing at Mo line, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Snlky Listerllow Corn- Planters, of which the following is a specificatlou.

This invention relates to sulky listcrplow cornplanters or seed-planters of that class in which a seedplauting apparatus is combined with a sulky or wheel plow in which the plow proper is preferably a lister or double-moldboard plow; and the improvements hereiir after described and claimed refer to construe tions and combinations in the sulky plow; to means for throwing the seeding devices into gear when the plow is lowered to work and out of gear when the plow is raised above the ground; to the means used for tightening the chain belt which drives the seed-droppers when the plow is lowered for planting; to the means used for adjusting thcinclination of the seed tube; to the means used for securing the plow-beam to the swinging hail of the sulky, and to the means used for locking the pawl carried by the plow-raising lever.

The means hercinbefore recited and others embodied in my invention are hereinafter fully described, and are summarized in the claims herewith.

In the accompanying drawings,which illustrate my invention, Figure 1 is a top plan showing the sulky lister-plow and the seeding devices, the seed box shown with the greater part of its lid or cover removed to show its interior; Fig. 2, a sectional plan of the plow in the line arm in Fig. 4; Fig. 3, a sectional plan in line y 1 in Fig. at; Fig. 4, a side elevation showing the apparatus seen at its left-hand side, the near wheel removed, the axle in section in line in Fig. l, and the plow in section in linear x in Fig. 3. This figure also shows a front elevation of the upper end of the seedtube; Fig, 5, a side elevation of the apparatus, seen at its right-hand side, the near wheel removed; Fig. 6, a side elevation of the lever for raising and lowering, the

of the lever shown at Fig. 6; Fig. 8, a perspective showing the seatand guidepole'supporting arch, a part of the axlc,.and the means for connecting it with said arch in full lines, and a part of the plow-beam, the means for securing it to the axle, and a part of one wheel in section; Fig. 9, a plan of the seed box and some of the adjacent parts thereto, seen from below.

In all of the figures of the drawings where shown the guide-pole is shown broken away.

Referring to the drawings by letter,thesame letter indicating the same part in the different figures, A represents an ordinary sulkyplow axle, bent or formed in an ordinary manner, with a double crank central part, a, and end parts, a. I

B is an ordinary arch, secured to the axle and adapted to support the guide-pole B, seat 13, and arc-shaped rack-bar b in an ordinary mannner.

I have shown the arch B mounted on the axle and secured thereto in the followingdescribed improved manner.

0 O are plates bolted one to each angle formed by the bend of the axle at the inner ends of its horizontal parts by staples O", as shown plainest at Fig. 8. Each plate 0 and 0 projects forward from the horizontal part a of the axle and has a bearing-hole, O, at its forward end, in which rests a stud, b", which projects from the lower end of the arch B. This conncetionof the arch Bto the axle forms astrong, simple, and cheap connect-ion and locates the arch B forward of the axle and in such relation thereto that the weight of the arch and parts connected therewith and of the driver will aid in raising the plow when the crank part of the axle is turned upward for that purpose. One end, G", oil the plate 0 is extended to strengthen and stiffen the axle at the part where the plateis located and to form a support for the lever D, which is bolted to a projection therefrom, which projection forms a part of said lover.

The arc-shaped rack-bar I) is provided with ordinary teeth, and is secured to the arch 13 by brackets b. The end a of the axle is the plow and the toothed rack-bar which holds i fulcrum for the lever D, and itwill be evident it; Fig. 7, a side elevation of the upper end that when the lever is swung to turn the axle the rack-bar b will move with the arch B in such manner that the rack-bar will not operate well, if at all, with the pawl d carried by the lever D if the curved rackbar is concentric with the fulcrum of said lever. To make these parts operative to the best advantage, 1 make the curved raelebarconcentric with the fulcrum b of the arch B to the extended for ward end of the plate 0. The pawld is fixed to the lower end of a rod, d, which extends to a projection, d, from the ordinary thumb-lever, D,which is pivoted at d' to the lever I). The thumb-lever D is drawn by the hand to retract the pawl (1 from the teeth of the rackbar, and is moved into engagement therewith by a spring, 61, in the ordinary manner, and my improvement in this connection is in the use of a lug, D, which projects from the side of the thumb-lever D, and with which the rod d will come in contact when the thumb lever is thrown over into theposition shown by dotted lines at Fig. 6 and full lines at Fig. 7,and thereby lock the parts and hold the pawl d out of engagement with the rack-bar when desired, thus forming a lock for the pawl without the use of links or other agencies which require to be operated by hand when the thumb-lever is operated.

E is thebeam, and E the double-moldboard plowan ordinary lister-plow. A frog, 6, is bolted in the lower part of the plow and carries a rearwardly-extending arm, 6, to one side of which the end of the plow-beam is bolted.

F F are clamp-plates, each provided with a projecting boss,j", on one side, which is suitably perforated to receive the crank-arm a of the axle. The clampplates thus constructed can he slipped over the ends of the axle and into place when the axle is free of the plates 0 O, and are then bolted to the plow-beam by boltsf. The bosses fare free to turn on the crank-arm (t of the axle. The draftanimals are hitched to the forward end of the plowbeam. The plow is raised and lowered and locked at different heights by the lever D in an ordinary manner.

G is the seed-box, hinged at g to arms or brackets g,which project from the rearwardlyextended end of the guide-pole, so that the seed-box isearried on the guide-pole. if the frame of the sulky is otherwise constructed, the seed-box can be secured to any suitable part of said frame. The hinge 9 permits the seed-box to swing rcarwardly at its lower end in a vertical plane. This seed-box has a hinged lid, 5/, and is provided with an ordinary seeddropping wheel, H, having seed-cups h. The seed-cup wheel H has a bevel-pinion, h, which gears with a bevel drive-pinion, 1, carried on a shaft, I, which is located transversely to and beneath the seed-box and has suitable bearings thereon. (See Fig. 9.) The shaft I has a limited endwisc movement, which movement is given it by a lever, J, pivoted atj, its inner end resting in a groove in the shaft I and its outer end formed into an inclined cam-plate,

j, which, when the plow-beam is raised, as

shown at Fig. 5, is struck by an inclined camplate, k, carried on the plow-beam. The camplate It will in striking the cam j, as last described, swing the lever J and force the shaft l into the position shown by full lines at said figure and out of gear with the seed-wheel, thereby stopging the rotation of the seedwheel. When the plow is lowered into the working position shown at Fig. 4- the spring I will force the shaft 1 in the direction shown by dotted lines at same figure, and thereby bring the pinion i into gear with the teeth It on the seed-wheel.

K is a sprocket-wheel, which is loosely mounted to turn on an end, a, of the axle, and which I have shown as fixed to a sleeve, k, which is connected with and rotates with the hub of one of the supporting-wheels L. will be evident that the sprocket K may be secured to the wheel-hub direct. A chain belt, in, gears thesproeket K with asprocket-wheel, l, on the outer end of the shalt I.

In raising and lowering the plow the guidepole and arch B will change their distance from the arm a of the axle on account of the arch being carried on the arms of the plates 0 0 forward of the axle, and thus the distance between the seed-box and arm a will be variable and the chain belt is sometimes slackened. To keep the chain at all times in proper taut working order, I use the bar M, which is seated loosely on the arm a of the axle at one of its ends, and at its other end loosely connected with the shaft Land this bar, when the seed-box tends to approach the arm a, will swing the seedbox on the hinge g and preserve an unvarying distance between the arm a, and the shaft I, and will thus keep the belt tight. The arm M is adjustable in length to properly tighten the beltas it becomes worn or for any other purposes found necessary, being formed of two end parts and a central part connected by bolts and slots at m, respectively, whereby the length of the arm M may be adjusted and fixed after adjustment in an evident manner.

N is the seed-tube, provided at its lower end with a suitable shoe or opener, n. The tube -N is adjustably held in rear of the plow by bars P and R. The bars P (see Fig. 2) are located near the top of the tube N, one on each side of the plow'bcam at one of theirends, and at their other ends on each side of a tongue or plate, n,which projects from the tube N. The platen has holes a for said connection, and the bars P have holes 1) for the boltp. The bars R are bent and fitted to the mold-board and to theplow-beain,(see Fig. 3,) and extend rearwardly one on each side of a tongue or plate, 8, which projects from the tube N. The plate 8 has a series of holes, 8. By means of the holes 3 and a" and their respective bolts the tube N may be adjusted and fixed after adjustment at different heights relatively to the plow, as indicated by dotted lines at Fig. 4, to regulate the depth of planting below the furrow made by the lister-plow, and by means of the series of holes 1) and boltp' the inclination of the tube N may be adjusted and fixed after adjustment to suit its operation in different soils.

The coveringblades T are fixed in rear of the tube N by a bolt, 1, which passes through the head ends of said blades and through a plate, '5, which projects in rear of said tube. The adjacent faces of the blades T and plate i are serrated to hold the blades T firmly after adjustment to change their depth of penetration of the soil or to lower them as they become worn, or for other purposes.

The canrplate It is located on the inclined part of the plowbeam, as shown, and has a slot, 75, through which a bolt, k, passes to secure it to the plow-beam. Should the plate k or other parts of the device become so worn as to interfere with the operation of the plate, it can be adjusted in a higher position on the plow-beam, and can be held after adjustment by the bolt to compensate for the wear and to cause it to operate effectually.

N is a flexible tube fitted over and held by a band, N", on a tubular projection, N,which connects with the discharge-opening'G in the bottom of the seed bo x. The tube N extends into the tube N. (SeeFig. 4-.) In this class of planter, in which the drivers seat is located in front of the sced-dropping mechanism, it is very desirable that the driver know with certainty that said seed'dropping devices are op erating effectively, and to provide means whereby he may know this with certainty I provide an opening, N, through the front side of the tubular projection N and through the tube N, which can either be left open or covered with any suitable transparent covering. The driver, by leaning in a suitable manner, can see this opening, and thus know when the seed is dropping properly. In planters of that class in which the driver isin rear of the seed-dropping mechanism means have been provided whereby he may see the seed asit falls to the ground; but none of these means would be operative with my device, in which the rear parts ofthe seeding mechanism are invisible to the driver from his seatin front of the seed-dropping mechanism.

The plow E may be set to run at different depths to suit different kinds of soil by adj usting the handlever D on the rack-bar b in the evident manner, and by locking the pawl d out of engagement with the rack-bar the plow will be free to rise and fall when desired to run it Y in that way, and at whatever depth the plow may be adjusted to run the bar M will,in connection with the swinging seed box, keep the drive-belt taut. The seed-box, being carried on the sulky-frame, will not be tilted and shaken as it carried on the plow, nor otherwise affected byraising and lowering the plow, and when the plow is raised above the ground theseed-droppi ng will bestopped,as described.
