LOUIS YIELKY, OF ROCK CREEK, KANSAS.

DISK MARKER.

SPECIFICATION forming part of Letters Patent No. 616,279, dated December 20, 1898.

Application filed Tune 27,1898.

Be it known that I, LOUIS YIELKY, of Rock Creek, Jefferson county, Kansas, have invented certain new and useful Improvements in Two-Row Disk Markers, of which the following is a specification.

My invention relates to what I term tworow disk markers for turning a furrow on plowed ground-that is, performing the work of a single plow or lister; and it consists in certain novel and peculiar features of construction and combinations of parts, as will be hereinafter described and claimed.

The object of the invention is to produce a machine of this character which may be adjusted lto accommodate rows of different widths and whereon the furrow-turning disks may be adjusted to vary the width or depth of the furrow.

A further object is to produce a machine of this character which is simple, strong, durable, and inexpensive of construction.

In order that the invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in which-'- Figure l is a side elevation. Fig. 2 is a` top plan view. Fig. 3 is a rear view showing the relation between a pair of the disks. Fig. 4e is a top plan View of the same on a larger scale, the scraper-arms being shown in section. Fig. 5 is a vertical section taken between the disks. Fig. 6 is a central transverse section. Fig. 7 is a top plan view of the disk-adjusting plates. Fig.` 8 is a view illustrating the relation existing between a disk and scraper.

In the said drawings, l designates a substantially horizontal U-shaped frame having its rear ends connected by a cross-bar 1a, carrying axle-stubs 1b, provided with Wheels 1c, which not only serve to support the operative parts above the ground in traveling to and from the lield, but also act as a guide to regulate the depth of cut.

2 designates a vertically-arranged U -shaped frame externally embracing frame 1 and secured thereto, as shown at 3. Said frame carries the tongue 4, and secured to the'latter is the standard 5, carrying seat 6.

An oblong rectangular frame is constructed as follows:

7 designates a transverse angle-iron arsenal No. 684,549. or@ moda.)

ranged a suitable distance below the frame l and slightly rearward of the frame 2.

8 designates a pair of longitudinally-ex tending bars having their rear ends bent downward, substantially like the ordinary shank of a cultivator, but provided at their front ends with the inwardly-turned slotted arms 9, which rest upon the horizontal flange of said angle-iron and are ad justably bolted to the vertical flange of said iron, as shown at 10. A pair of angle-brackets consist of the yarms 11, bolted to the inner sides of bars 8, as shown at 13,'and the transverse slotted arms l2, which overlap each other and are adj ustably secured together by means of the clamping-bolts 14. By this arrangement it is obvious that said oblong rectangular frame may be lengthened or shortened in order to accommodate the machine to rows of varying widths.

15 designates a substantially U -shaped bail which is pivoted in the lower ends of frame 2, and 16 a clip uniting said bail and the doubletree 17.

The oblong rectangular frame above described is provided at its front end with brackets 18, pivotally mounted upon the bail coincidentally with the pivotal point of the latter in the frame 2, as shown clearly in` Fig. 1, and 19 designates inclined braces which are secured at their lower ends to the lower end of the said frame and at their'upper ends to the tongue.

20 designates the curved shanks of the cultivating and in this instance subsoil shovels 2l, said shanks being secured to the bars S, as shown at 20, or in any other suitable manner.

In this machine there are two sets of furrow-turning disks or markers, one set in advance of each subsoil-shovel 2l, and as said sets are of duplicate construction a description of one will suiiice for both.

Referring now to Sheet 2 particularly, 22 and 23 designate a pair of companion diskadjusting plates, said plates being provided with inwardly-projecting overlapping baseflanges 22 and 23, respectively, and said anges are provided with central `registering apertures 24 and with segmental slots 25, the slots of one iiange registering with those of the other and all struck from the center of the apertures 24. rIhe clamping-bolts 26 ex- IOO tend through said registering slots, and by means of said bolts the disk-adjusting blocks may be clamped at any desired point of adjustment-that is to say, may be clamped so as to cause their side margins to converge forwardly more or less, as shown, to extend parallel or to diverge forwardly, if ever necessary or desirable. A pivot-bolt 27 extends through the registering opening 24, and upon said bolt the adjust-ment is made. Just above said flanges 22t and 23a the blocks are provided with segmental grooves 28, extending concentrically of said bolt and with grooves 29 in their side edges, said grooves being substantially T-shaped in cross-section (see Fig. 6) and enlarged at one end, as shown at 30, (see Fig. 5,`)as will hereinafter appear.

3l designates a standard which is provided with a pair of parallel arms 32, which embrace loosely opposite sides of the lower end of the bar 8 (see Fig. 5) and are pivoted near their lower ends to the lower end of said bar, as shown at 32a. They are also provided with a series of holes 32b in their upper ends, arranged concentrically of the pivot-bolt 32, and extending through the bar 8 and through one or another of the sets of holes 32b is a bolt 33. Then this bolt occupies the middle hole 32", the standard is vertical. When it occupies the hole to the rear of hole 32h, the standard is tilted forwardly, so as to rotate the disks hereinafter described a certain distance in the direction indicated by the arrow, Fig. 5, and 'when the bolt occupies the opening forward of the central hole it is obvious that the standard will be tilted rearward and downward, and the disk therefore rotatably adjusted in the opposite direction to that indicated by the arrow. The standard is also provided with an enlarged circular base 34, which rests upon the flange 22 and engages the segmental grooves 28 of said blocks. (See Figs. 3, 4, and 6.) To still further secure said standard in position, it is engaged by the pivot-bolt 27. The base-flange of said standard is provided with a pair of longitudinallyalined lugs 35, which overlap the slots 25 of the blocks, and through said lugs the clamping-bolts 26 also extend.

36 designates bolts provided with rectangular heads 37, and one of said bolts projet-ts outwardly from and at right angles to the side of each block 22 and 23. To secure said bolts in position, their heads are iirst slipped into the grooves by way of the enlargements 30 and then slid forward in a manner which will be readily comprehended.

38 designates the scraper-arm or standard mounted upon each bolt 36, and said standards are provided at their upper ends with the angle-knives 39, said knives being provided with slots 40, through which clamping-bolts 40 of arms 38 extend. By this arrangement the knives may be adjusted toward or from said arms, as will be readily understood by reference to Fig. 8. Said arms are provided at their lower ends and inner sides with grooves 4l and at their outer sides with sock ets 42, the former fitting snugly over the adjacent disk-adjusting blocks.

43 designates the disks, which are provided with hubs consisting of an outer section 44 and an inner section 45, secured together and to the interposed disk by means of the bolts or rivets 46, and the inner end of said hub is grooved or turned out, as shown at 47.

48 designates a sleeve mounted upon each rod 36, and journaled thereon are the disks 43.

As the inner ends of the disk hubs which project into the sockets 42 of the scraper-arms 38 occupy the same vertical plane, practically, as the corresponding ends of said sleeves a ball race or chamber is provided at this point, due to the existence of the grooves 47 in the inner ends of said hubs, and occupying said chamber or groove are a series of bean ing-balls 49, which by their position receive the end thrust or pressure of the disk hubs, and thereby reduce friction to the minimum at this point.

A dust-proof cap 50 lits over the outer end of each disk hub, and a clamping-nut 5l, engaging the bolt 36 and bearing against the outer side of said cap, holds the disk reliably in position.

From the foregoing it will be apparent that as the bolts 36, upon which the disks are mounted, project at right angles from the blocks said disks are parallel as long as the blocks remain in the same condition, but may be brought nearer together at their front edges, or, in other words, may be caused to converge by rotating said blocks inward and forward upon the pivot-bolts 27, as illustrated in Figs. 4 and 7 most clearly. If their front edges cannot be brought suiciently close together by this adjustment, the distance between said edges may be still further reduced by sliding the bolts 36 forward in the slots 29, as indicated, for example, in dotted lines a, Fig. 4. If this adjustment does not bring the cutting edges of the disks sufliciently close, they may be brought still nearer by ro tatably operating them. To make this latter operation clear, it is desirable to state that the edges of the disks nearest together after the two previous adjustments are those which lie in the horizontal plane of the centers ofthe disks, as at b, Fig. 5. Therefore to bring nearer together the cutting edges,which are of course always vertically below the disks axes, the rotation of the disks from the position indicated by b, Fig. 5, to the position indicated by c, same gure, will obviously cause the distance be tween the cutting edges to be correspondingly narrowed, as the narrowcst space between the disks-viz. ,at c-is nearer to the cutting-plane than it was before such rotatable adjustment. The relation between the disks 43 and the Scrapers 39 is such that the latter prevent the accumulation of dirt on the outer or exposed surface of the former, andthereby keep them in good operative condition.

In practice as the machine is drawn across IIO the field said disks, properly adjusted, not only cut down any growing Weeds in their path, but also turn a furrow and expose the subsoil, which is acted on with more effect than could be obtained if the markingdisks or furrow-turners were not employed.

The width of the furrow of course is determined bythe angle of the disks,and said disks may be caused to cut and the shovels to cultivate more deeply by mechanism described as follows: 52 designates a transverse shaft journaled on the frame 1 and provided with a pair of crank-arms 53, connected by links 54 to the bars 8 of the pivoted disk and shovelcarrying frame. A lever 55, mounted upon said shaft, is provided with the customary spring-actuated dog 56, for engagement with the sector 57 upon frame 1, and also with a pivoted grip 58, connected to said dog to withdraw it from engagement with said sector. When going to or returning from the field,said lever may be manipulated so as to raise the disks and shovels to an inoperative position, as will be readily seen.

From the above description it will be apparent that I have produced a machine of the character described which embodies the features of advantage enumerated as desirable; and it is to be understood that I reserve the right to make such changes as do not involve a departure from the spirit and scope or sac-Y ritice any of the advantages of my invention.
