DISK FURROW-OPENER.

SPECIFICATION forming part of Letters Patent No. 744,711, dated November 24, 1903.

Application filed March 28, 1903.

To all whom, it may concern:

Be it known that I, WILMONT BILLS, a citizen of the United States, residing at the city of Dowagiac, in the county of Cass and State of Michigan, have invented certain new and useful Improvements in Disk Furrow-Openers, of which the following is a specification.

This invention relates to improvements in diskfurroW-openers. Itis particularlyadapted for use in grain-drills, although desirable for use in other relations.

The objects of the invention are to provide an improved disk furrow-opener in which the disks are satisfactorily cleaned and the collection of soil and trash prevented.

A further object is to provide an improved scraper mechanism for disk furrow-openers in which the tension can be quickly and easily adjusted.

Further objects will definitely appear in the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is fully illustrated in the accompanying drawings, forming a part of this specification, in which Figure 1 is a detail side elevation view of a double-disk furrow-openerembodyingthefeatures ofmy invention, portions being broken away to show the arrangement of the parts. Fig. 2 is a detail sectional view taken on line 2 2 of Fig. 1. Fig. 3 is an enlarged detail sectional view taken on lines 3 3 of Figs. 1 and 4. Fig. 4 is a detail View taken on line 4 4 of Fig. 3. Fig. 5 is a detail sectional view taken on Fig. 6 is a detail plan view showing the spring-pressure connection for the scraper-blades F for the inner faces of the disk, and Fig. 7 is a plan View of one of the scraper-blades F.

In the drawings the sectional views are taken looking in the direction of the little arrows at the ends of the section-lines, and

similar letters of reference refer to similar SerialNo.150,07 l. (No model.)

ings, the boot A is of the usual or any desired form. The bearings for the disks B 13, also of any desired. form, are carried by the boot.

Projecting forwardly from the boot A is a bracket A, to which the draw-bar A is secured. On each side of the bracket A are projecting lugs (0, which are provided with suitable hearings to receive the journals of the brackets O, by which the scraper-blades are supported. The scrapers D are adapted to rest against the outer faces of the disks. Pressure is applied to these scraper-blades by blade-springs O C, which are secured at one end to the brackets O and are adjustably secured together at the opposite end by a link E, into which the bolts 6, which are passed through the ends of the springs, are threaded. The bracket A is provided with a suitable perforation or opening E, through which the link E extends, so that the tension upon the scrapers D is capable of complete and easy adjustment and the tension on the two blades is equal at all times.

The blades D are pivotally secured to the brackets O by heads cl, which are journaled upon the pivot c of the bracket 0. These heads d are preferably formed of malleable iron with extending lugs at each side, so that the scraper-blade may be placed in position and the lugs hammered down upon the same, as clearly appears in l and 4. They are also provided with a lug at f, which is adapted to engage the flange 0 to retain the head upon the pivot. By this structure the parts may be produced very economically and they are conveniently and economically assembled, and should the blades D become worn new ones may be readily inserted. By this arrangement of parts the blades are held against the disks by a yielding pressure and are perfectly free to yield to any obstruction, so that wear upon the same is reduced to a minimum and also the danger of breaking the supports.

The inner faces of the disks B are freed from soil, and the accumulation of trash is prevented by scraper-blades F, which project between the same to the rear of the boot. (See Figs. 1 and 5.) These scraper-blades F are supported-upon a bracket A, which extends rearwardly from the boot and areheld against the innerfaces ofthedisksbyspring-pressure. The scraper-blades F are slotted at n to engage the pin g on the bracket A and are pivotally secured together at their inner lower ends by a suitable rivet or the like g. Aspring 71, which is retained in position by a pin it, engages suitable perforations in the upper ends of the blades F, so that they are held outwardly against the inner faces of the disks. The spring 72 is formed in one place so that the scraper-blades F are held against the disk with an equal pressure. Several perforations n are provided in the upper edges of the blades to engage the spring 7t, so that the tension can be adjusted or the blades can be adjusted to compensate for wear. This scraper is also very easy to construct and quickly assembled. In assembling, the ends of the spring h are engaged in perforationsin the upper ends of the blades, and the blades are swung down between the disks onto the pin g and there retained by a suitable cotter-pin or the like. By this arrangement of parts the pressure is applied to the scraperblades in a simple and satisfactory manner. A structure is produced which is economical and durable.

I have illustrated and described my invention in the form preferred by me on account of its simplicity and economy in manufacture anddurability in use. I am aware, however, that it is capable of very considerable variations in structural details without departing from my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
