DISK FU RROW-OPEN ER.
I SPECIFICATION forming part of Letters Patent No. 747,759, dated December 22, 1903.
Applioationled September Z1, 1903. Serial No. 173,928. (No model.)
To a/ZZ whom it may concern:
Be it known that I, FRANK R. PACKHAM, a citizen of the United States, residing at Springfield, in the county of Clark and'AStale ot Ohio, have invented certain new and usel'ul Improvements in Disk Farrow-Openers, of, which the following is a specification.
My invention relates to improvements in furrow-openers for grain-drills, and particularly to furrow-openers of the double-disk type.
The object of my invention is to provide a scraper for the inner sides of the respective furrow-opening disks, the especial object being to provide a scraper which can be quickly and easily adjusted to its proper working position against the sides of the disks and one which in any of its adjusted positions will always properly conform to the shape of the disks.
The invention consists in the constructions and combinations of parts hereinafter described, and set forth in the claims.
In the accompanying drawings, Figure lis a sideelevation ot' a furrow-opener of the double-disk type to which my invention has been applied, one of the disks being` shown removed to better illustrate the parts. Fig. 2 is a sectional view, the section being taken through the disks on the line :1; :n of Fig. l. Fig. 3 is adetail of a portionrof the scraper.
Like parts are represented by similar letters of reference in the several views.
The particular construct ion offu rrowopen ingvdevice which I have illustrated iu the drawings is described in my pending application, Serial No. 173,089, filed September I4, 1903, and may be briefly described as follows: a represents the bearing support or frame .for the disks b, said disks being journaled in said support or fratne in theinanner described in said application. The said support or l'ratne d is formed with a grain-conduit d' in front ot" the axial vcenter of the disks, the conduit having a curved discharge-opening a2 to detlect the grain to the rear of a vertical line through the center of the disks, a grain-spout d3 leading int-o the upper end ot' said' conduit.
d4 represents anoil-conduit secured to the supporting-frame d,'and d5. the attachment for the usual drag-bar.' VTo a suitable point on the said supporting-frame a between the respective disks b I secure my improved scraper c. In the present form of device I have chosen this point as that part of the supporting-frame in the rear of the oil-conduit a", which'portion of the frame extends backwardly and upwardly from the axial center of the disks. The scraper c consists of two plates c' and c2, said plates heilig pivoted at their lower or inner ends to theI said support a, as shown at c3 and c4, saidA pivotal pointsy being located in proximity to the central bearing for the disks. The said plates o and c2 extend along the supporting-frame to the outer peripheries of the said disks and each of said plates is formed on the side adjacent to its corresponding disk of a :shape lo conform to the contour of the disk.
The outer portions of the plates c c2 overlap, as shown, and are provided with slotted openings c5 c6,registering with each other when the plates are in position, the said plates being secured to the outer part of the supportingframel by means of a screw c7 or other suitable fastening device, which extends through the slotted openings. By loosening the fastening c7 the plates can be moved on their pivots c3 and c4 to or from the disks by reason of the slotted openings.
` By this construction I have .provided a scraper for the disks which can be easily adjusted laterally to and from the disks tol provide for taking up wear thereon and also to provide for the changing positions ot' the disks when taking up the wear of the diskbearings.
By making the scraper-'s adjustable laterally I am enabled to form the scraping edges of the scraper of a shape to more nearly conform to the shape ofthedisks, especially when disks like those shown in the drawings are employed having straight or flaring edges.
Having thus described my invention, I claim- V l. The combination of double disks, asup porting-frame, a discharge-opening in said frame located in front of the axial center of thedisks with itslower end curved rearwardly to deflect the seed to a point below and in the rear of the axial center of said disks, and a scraper secured to said support, said scraper being located on the opposite side of the axial center of said disks from said dischargeopening, substantially as specified.
2. In a double-disk furrow-opener, a supporting-frame, double converging disks supported by said frame, serapers pivoted at their lower ends and formed with slots in the other end, and means for adjusting laterally said scrapers, for the purpose specified.
3. In a disk furrow-opener, asupportingframe, double converging disks supported by said frame, double Scrapers pivoted at their lower ends, adjustable devices at their other.
