DISK MARKER.

SPECIFECATION forming part of Letters Patent No. 747,754, dated December 22, 1903.

v Application filed April 8, 1903. Serial No. 151.640. 1dio model.)

To all whom t may conce-rn,.-

Beit known that I, CHARLES H.MYERS, a citizen of the United States, residing at Leroy, in the county of McLean and State of Illinois, have invented a new and useful Disk Marker, of which the following is a specification. y

My invention relates to marking devices of the class which are used in connection with seed-planters for the purpose of guiding the driver after the planting of the rst row in order to make the succeeding rows parallel therewith, and it has special reference to that class of devices in which the marker is composed cfa disk.

The object of my invention is to provide a device of this class in which the disk may be easily and quickly adjusted to any desired angle.

A further object of my inventionl is to provide adevice in which the disk shall be mounted in such a manner that the bearing thereof shall be practically dust-proof.

Another object is to provide a device which may be readily and quickly connected with a planter of any kind.

With these and other objects in view, all

` tending toward the production of a device of the rod whereby it is connected with thel planter. Fig. 2 is a rear perspective view of my improved disk marker, showing a portion of a pipe or tubular rod wherebyitis connected with a planter. Fig. 3 is a central sectional View of my improved disk marker and the attaching-bracket which constitutes a portion thereof.

Corresponding parts in the several figures are indicated by similar numerals of refer-v ence.

1 designates a block, which may be square or rectangular and is provided on one side thereof with a laterally-extending tapering spindle 2, at the base of which. an vannular groove or recess 3 is formed in the block. The

latter is provided on its opposite or inner side p with a longitudinal recess or cavity 4, which isV bounded by tianges 5 5 on either side thereof, said recess being in the nature of a segmental depression in the inner face of the block l, with which the tlanges are obviously 6o integral. A perforation 6 extends through the spindle 2 of the block 1.

7 designates a hub having a tapering bore whereby it Ais fitted upon the tapering spindle 2. Said hub is rounded at its inner end, as shown at 8, to engage the annular groove 3, in which the said rounded inner end of the hub is closely seated. The -outer end ofthe hub is interiorly beveled, as shown `at 9, to

vafford a` seat for a beveled washer 10, which 7o is seated upon a bolt l1, extending through the perforation 6 in the spindle, the outer end of said bolt beingprovided with a tightening-nut 12.

The hub 7 is provided near its inner end 75 with an ann ular flange 14, to which aconcavoconvex steel disk 15 is suitably connected by means of rivets 16 or equivalent means.

17 designates the attaching-bracket, which consists of a stout strap of iron curved seg- 8o mentally at the end where it is connected with the block 1 and provided in said curved portion with a longitudinal` slot 18, through which the connecting-bolt 11 extends,awasher 19 being interposed between the head of the 85 bolt and the slot, so as to form a rm and rigid connection. The curve of the strap 17 is of less radius than that of the segmental recess in the block 1, in which the said curved portion of the connecting-strap is seated. It 9o follows that a comparativelyshort adjustment will considerably change the angle between the connecting-bracket and the disk, which F latter may thus by merely operating the nut 12 be easily and quickly changed to anypo- 95 sition which it may be desired that it shall occupy.

The connecting-strap 17 is provided with perforations or bolt-holes 20, enabling it to be lconnected by means of bolts tovan ordiloc nary Wooden rod, as shown at 21 in Fig. lof the drawings. kIf preferred, the connectingstrap may be secured by means of clips 22 with a pipe or tubular Vrod'23,v as shown in' Fig. 2 of the drawings. In either case the connecting-rod 23 is to be suitably connected with the planter-frame, with which it is furthermore connected by means of a brace or guy-Wire 24:.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of my invention will be readily understood. My improved disk marker when attached to a planter will cnt into the ground, no matter what the condition of the soil may be, and leave a clear and distinct mark which may be clearly seen by the driver a long way ahead, thereby enabling him to keep the machine in the proper direction. Weeds and grass roots, as well as other similar obstructions, will not accumulate or hang upon the marker, but will be cut, thereby enabling the driver to proceed without necessity of stopping for the purpose of clearing the marker. Other advantages resulting from my improved construction will readily suggest themselves to those skilled in the art to which it appertains.

The device is extremely simple in construction, and it may be manufactured separately and applied to seed-planters of any known pattern. Itis obvious that the method of attaching may be varied within the scope of my invention; also, that I do not limit myself bythe structural details herein set forth, but reserve the right to any changes, alterations, and modifications within the scope of my invention and which may be resorted to without departing from the spirit orsacriiicing the utility of the same.

Having thus described my invention, I claiinl. A disk marker for planters comprising a block having a segmental recess in one side and provided at its opposite side with a tapering spindle and an annular groove surrounding the base of the same, a hub engaging said annular groove and having an interiorly-beveled outer end, a disk mounted upon the hub, a connecting-strap having a curved slotted end engaging the segmental recess in the block, a bolt extending through the slot of said connecting-rod and through the spindle, a washer upon said bolt seated in the beveled end of the hub, and a tightening-nut.

2. In a device of the class described, a diskcarrying block having a segmental recess, in combination with a curved slotted strap engaging said recess, and connecting means.

3. In a device of the class described, a diskcarrying block having a segmental recess in the rear side thereof and flanges adjacent to said recess, in combination with a strap curved to engage said recess between the flanges thereof, and connecting means.

4E. In a device of the class described, a block having a spindle and provided in its opposite side with a segmental recess, a disk-carrying hub mounted upon said spindle, a connecting-strap having a segmentally-curved slotted end, a bolt extending through the slotted end of said strap and through the spindle, a washer upon said spindle engaging the outer end of the hub, and a tightening-nut.

In tesiimony that I claim the foregoing as my own I have hereto aiixed my signature in the presence of two witnesses.

CHARLES I-I. MYERS.
