SPECIFICATION forming part of Letters Patent No. 60;},634, dated June 14, 1898.

Application filed November 12, 1897:. Serial1 lo. t58,324.' (No model.) I

To all whom it may concert 1.; j Be it known that I, WILBUR'O. DURYEA, a

' resident of Morning ,Sun, in the county of Louisa and State of Iowa, have invented cer-' tain new and useful Improvements in chec Rowers for Corn-Planters; and I do hereby declare the following to be a full, clear, and ex-' act description of the invention, such as will enable others skilled in the art to which it appertains to makeand use the same.

My invention relates to an improvement in automatic check-rowers for corn-planters, the object of the invention beingtoprovide'sim; ple and efficient means for operating the drop ping mechanism of a corn-planter so that the seed will be dropped in straight lateral rows, or, in other words, so that the rows will be in perfect check without the use of a line or wlre.

A further object is to provide a check-rower with simple means whereby to accurately operate markers without the use of wires.

With these objects in viewthe invention consists in certain novel features of construction and combinations and arrangements of.

out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a part of a corn-planter and showing a side view of my improvements. Fig. 2 is a'plan' view. Figs. 3 and 4 are detail views of lugs or projections on some of the links of, the sprocket-chains. detail elevation of the front axle and mountings of the same. Fig. 6 illustrates the form and construction of the frontwheel, and Fig.

parts, as hereinafter set forth, and pointed 7 is a perspective viewof one of the markers.

A represents a portion of the frame of an ordinary corn-planter; B, the-main axle; C, the carrying-wheels, and D'the tongue; A screw 1 passes through the tongue and is held in proper position by means ofjam-nuts2, the upper end of saids'crew being provided with a loop or eye 3 and the lower end made to enter a casting 4, which serves as a bearing for a revoluble shaft or axle 5. The shaft or axle 5 also has bearings near its ends in T-couplings '6' 6, which are connected together by means of a trussrod 7, passing through'the loop or eye 3 on the upper end of screw 1.. The revoluble shaft 5 is prevented from longitudinal movement in its bearings Fig. 5 isa by means of collars 8, secured thereto by 11163111501 set-screws and adapted to bear against the respective ends of thecasting 4.

. gitudinally the side rods or'bars9 are each made in two sections connected together by meansof turnbuckles 12. The frame is also braced by Ineansof diagonally-disposed rods Ior bars 13, connected at their forward ends to the easting4 by means of suitable staples 14 and connected at their rear ends in a similarnianner to the fixed shaft 11. It is apparentthatwhen the frame isadjusted the connections of the rear ends of the rods or bars 13 with the fixed'shaft will be moved toward or away from each other as the frame is lengthened or, shortened.

Sprocket-wheels 15 are secured to the rev= oluble shaft 5, and sprocket-wheels 16 are mounted loosely on the respective ends of the fixed shaft 11. Over these pairs of sprocketwheels sprocket-chains 17 pass, and it is for the purpose of tightening or regulatingthe tension of these chains that the said frame is 'made adjustable, and in order that said frame may be pulled forward properly as the apparatus rnovesforwardly and without putting too much strainon the bolt orscrew 1 the center of the casting is connected withthe tongue by means of a brace or truss rod 18.

.Each wheel 15is made of such size that one- ,half a revolution'of the same will represent the distance between two rows,and each wheel ispprovided at diametrically opposite points with markers 19. Thewheels 15 and 16 are so arranged with respect to each other that the sprocket-chain 17 will pass over the ground from one wheel to the other. Some of the links of each chain are provided with lugs 2O, (preferably having sharp free ends 21,) adapted to enter the ground as the machine moves forward and thus insure the accurate rotation of the wheels 15 16,and consequently the accurate marking of the rows. In order to prevent dirt from packing under the sprocket-chains as they pass over the wheels 15, the rims of saidwheels are made triangular in cross-section, so as to present a sharp edge a and inclined faces Z). The wheel 15 is also made with enlargements for the acconnnodation of the sprocket-teeth 0. Between the sprocket-teeth transverse enlargements (1 are formed and adapted to serve as seats for the links of the chain having the lugs 20 thereon, and said enlargements d are preferably made diamond-shaped, so as to present sharp edges and inclined or beveled faces. When the rims of the wheels 15 are thus constructed, there will be no danger of dirt packing between the sprocket-chains and the rims of the wheels.

The rear wheels 16 are made much smaller than the wheels 15, and, as hereinbefore intimated, are mounted loosely on the fixed shaft. These wheels are made with rims triangular in cross-section and may be made without sprocket-teeth, if desired, and in fact I prefer to make these rear wheels without sprocket-teeth. In order to properly guide the chains over the rear wheels 16, the latter are provided with U-shaped projections 22, which embrace the chains as they pass over said wheels 16, and to further insure against the chains becoming clogged with dirt the illner edges of the projections 22, which engage the chains, are preferably made sharp.

The revoluble shaft 5 is provided with an adjustable collar 23, provided at diametrically opposite points with pins 24, adapted to operate the dropping mechanism (not shown) and are adapted to act in unison with the marking devices, so that whenever one of the markers engages the ground the seed will be dropped.

A shaft 25 is mounted on the main frame A of the planter and provided between its ends with an arm 26. To the free end of this arm a link 27 is pivotally connected, and to the lower end of said link the upper ends of two chains 28 28 are secured. The lower ends of the chains 28 are attached to the rods or bars 13, or, more properly speaking, said chains are attached to a cross-bar 30, disposed under the bars 13 under the rear end of the tongue. The shaft 25 is provided with an operating-lever 31, having a locking-dog 32 to engage a toothed segment 33 on the frame A. By means of the lever 31 and cooperating devices the frame can be raisec, as usual, and at the same time my impiJved checkrower devices will be raised also.

In operation the planter is driven across the field at one side thereof and the markers permitted to leave an impression in the ground at every hill or place where the seed is to be dropped. The driver will then at the end of the rows raise the frame out of the ground in the ordinary way, and the machine will be turned around, when the driver will lean over and turn the sprocket-wheels until one of the markers on the chain is in alinement with an impression left by the marker in the row last made. The driver will then lower the frame and proceed across the field.

It is evident that instead of providing the chains and marking devices at both sides of the machine a single set of these devices may be employed at one side of the machine.

Various slight changes might be made in the details of construction of my invention without departing from the spirit thereof or limiting its scope, and hence I do not wish to limit myself to the precise details herein set forth.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is- 4 1. The combination with the frame of a cornplanter and a tongue, of a frame connected with said tongue, wheels carried at each side of said last-mentioned frame, a chain passing over each pair of Wheels and adapted to engage the ground, markers on one wheel of each pair, and means for raising said lastmentioned frame, substantially as set forth.
