DISK ATTACHMENT FOR GRAIN-DRILLS.

SPECIFICATION forming part of Letters Patent No. 654,037, dated July 17, 1900.

Application filed Merch Z9, 1900. Serial No. 10,590. (No model.)

To @ZZ whom t may concern:

Be it known that we, STEPHEN B. ToLsoN and ANDREW `SOHOPP, citizens of the United States, and residents of Belleville, in the county of St. Clair and State of Illinois, have invented certain new and useful Improvements in Disk'Attachments for Grain-Drills, tbc. of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

Our invention relates to a novel manner of mounting groundsworking disks that are used in connection with grain-drill shoes, as shown, or independently thereof, our object being to so mount the disks as to afford for their adj ustment to any desired angle relative to the drag-bar, while they will be rigidly held at any angle to which they may be placed.

Our invention consists in features of novelty hereinafter fully described, and pointed out in the claims. y

Figure I is a perspective view illustrative of our invention. Fig. II is a top or plan view. Fig. III is an enlarged view of the box or housing by which the disk and shoe are attached to the drag-bar. Fig. IV is Aan enlarged vertical section taken on line IV IV, Fig. II. Fig. V is an enlarged vertical section on line V V, Fig. I. Fig. VI isla horivzontal section on line VI VI, Fig. V. Fig. VII is a detail perspective view showing the inner end of the arm of the shoe that is attached to the dragbar. Fig. VIII is a side elevation. Fig. IX is a section on line IX IX, Fig. VIII.

Referring to the drawings, 1 represents a drag bar, which may (with a number of mates) be made fast to the frame of a graindrill by means of a rod 2.

3 is one of the shoes of a grain-drill, made hollow, as usual, to receive one of the feedtubes. (Not shown.) The shoe has an inwardly-extending portion 4 cast thereon, (see Fig. IV,) to which one end of a sleeve or tube '5 is held by a bolt 6. The sleeve or tube 5 forms the journal for the hub 7 of the disk 8, the hub being held from outward movement on the journal by a shoulder or flange 9 on 5o the outer end of the journal.

hub 7 and provided with an oil-hole 11. Between the hub and the box there isl an oilspace 12. The outer end of the box bears against the periphery of the iange 9, and its inner end bears against a shoulder 13 on the hub 7.

The box or housing l() is provided with an arm 14, that is pivoted to the drag-bar by a bolt or pin 15 and having also a slot-and-bolt connection 16 with the drag-bar. The box or housing thus serves to connect the disk to the drag-bar, and by loosening on the bolt 16 the disk can be adjusted to any desired angle, as shown by full and dotted lines, Fig. II, and then by tightening the bolt the disk is held to whatever angle it may be adjusted. To avoid any possibility of the disk moving from vits adjustment when at work, the shoe 3 is provided with an arm 17, that has aslot and-bolt connection 18 with the drag-bar, the

adjustment being made here at the same time as the adjustment of the arm 14. There is a connection thus made between the dragbar and the disk on both sides of the latter:- by the box 10 and its arm 14 on one side and by theshoe 3 and its arm 17 on the other side so that the disk cannot possibly move from its adjustment.

20 represents a scraper for cleaning the disk, the arm 21 of which is made fast to the shoe 3 by a slot-and-bolt connection 22. (See Figs. I, V, and VI.) It is important that this scraper be so arranged that it can be efciently and quickly adjusted to the disk as it becomes worn. This We accomplish by forminga concavo-convex bearing 23 between the shoeand the arm of the scraper, as shown in Fig. V, so that when the bolt 22 is loosened and the arm moved downwardly the scraper will naturally be moved inwardly against the disk.

The scraper cleans one side of the disk as it cornes out of the ground, and to clean the other side of the disk we form the shoe with an inturned edge 24, (see Figs. VIII and IX,) that scrapes against the disk and cleans it as it comes ont of the ground.

We claim as our inventionl. The combination of a'drag-bar, a disk pivoted to the bar, a shoe to which the disk is journaled, and an arm` on the shoe and IOO which is adjustably connected to said bar, substantially as set forth.v

2. The combination of a drag-bar, a disk, a. box inclosing the journal of the disk and provided with a lug that is pivoted to the bar and has a bolt connection therewith, and a shoeto which the disk is journaled and which l is provided with i an arm having a slot-andbolt connection with said bar, substantially as set forth.

3. The combination of a drag-bar, 'a shoe having an arm adj ustably connected to said-i bar, a. journal connected to'said shoe,`a disk h In presence of"- having a hub fitting over said journal and a box inclosing said hub and having an` arm` that is pivoted to said bar and has also a slotand-bolt connection therewith, substantially asset forth.

4. The combination of a disk, a shoe to which the disk is journaled, and a scraper adapted to bear against the disk and having an arm that is connected tosaid shoe by a "bolt-and-slot connection; said armhaving al concave-convex bearin g against the shoe, substantially as and for the purpose set forth.

In testimonywhereof We have hereunto set our hands lthis 26th day of February, 1900.
