DISK DRILL.
SPEC IFICAT I ON forming part of Letters Patent No. 631,135, dated August 1 5, 1899.
Application filed June 22,1899. erial N0. 721,455. (No model.)
T0 at whom it may concern.-
Be it known that 1, WILLIAM STEPHENSON, a citizen of the Dominion of Canada, residing at Morris, in the county of Provencher, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Disk Drills; and I do hereby declare that the following is a full, clear, and exact description of the construction and Operation of the same.
My present device relates to further improvements in the class of machines above named by which the machine is rendered more perfect in operation by constructing the parts in such a manner as will prevent earth from accumulating between the disks and inconveniently clogging them and hindering their proper and easy working. I attain this object by mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of the grainspout casting as now constructed. Fig. 2 is a side elevation of the same with the addition of disks attached thereto and portion of drawbar. Fig. 3 is a rear view of the grain-spout and standard with a portion of the curved arm broken away. Fig. 4 is a rear elevation of the device as shown at Fig. 2. Fig. 5 is a rear view of the curved scraper. Fig. 6 is a longitudinal section taken on the line a: a: of Fig. 2..
In the drawings, A represents the grainspout casting as at present constructed, in which b is the top opening for the admission of the seed to be sown.
c is the circular corrugated projection to which the draw-bars g are bolted.
(l is the oil-conduit.
e e are the two hollow tapering axles.
g is the rear frame, formed quartei -circle shaped, with its lower portion elongated in a curve inward in such a manner as to allow a space a of about two and a quarter inches from its inner end to the axles e and strengthened by a brace 2, connecting the frame with the axle-standard, as shown at Fig. 1. On the said frame 9 is cast alug h, which is provided with a threaded hole to receive a corresponding threaded tap-screw Z after the latter has passed through the slot j of an inner scraper D, the scraper being located between the disks 0 and curved to conform to the outer surface of the lower portion of the said rear frame. The scraper impinges on the inner surface of each disk and keeps the same clear of earth during the operation of the machine. Any earth that may be carried up by the disks and dropped between them above the scraper D falls out through the space a, which thus prevents clogging.
In order to keep clear those portions of the disks around the axles not operated on by the curved scraper D on account of the opening a between the end of the frame 9 and the axles, I form two sharp-edged projections m m on the standard portion of the grain-spout casting A from the axles upward equal in extent to the width of the opening a, and each having-a slant to correspond to the position of the disks 0 O, which as they 'revolve slightly impinge on the said projections m m and so clean the central part of the said disks not acted upon by the curved scraper D. It will be seen that the projections m m form a scraper separated from the curved scraper D to permit the passage of earth, as before described. It will be observed that the surface of said projections m m will be of chilled metal and that the said projections are cast on the standard, and hence will not vibrate and will be noiseless during the operation of the machine. The chilled faces of the projections are always in proper position to fit the disks without any tool-fitting whatever.
An eye at is attached to the rear portion of the curved frame 9 for the purpose of securing thereto a drag-chain 0 to cover the grain in the furrows like a harrow after planting. Also two parallel lugs p p, three-eighths of an inch apart, are cast above the eye n on the said curved frame g, having a hole through each opposite to one another and are for the purpose of securing thereto,by abolt,a spring and press-rod q, the other end of which is attached to the ordinary presser-arm of the seeding-machine (not shown) for lifting the disks out of the ground or pressing them in, as desired; but I claim nothing on the mechanism for accomplishing the same.
It will be observed that the curved arm g as constructed to form the opening a between its end and the standard may be tapered to conform to the divergence of the disks, so as to correspond to the space between them and act as an inner scraper to keep the disks clean, except in the center, in the same manner as the projections m on the standard clean the center of the disks in proximity to the opening a, and it may further be seen that its edges may be chill-hardened, and it may be used as a scraper until the outer edges wear down, when a curved scraper, as D, may be adjusted thereto by a bolt l, made to pass through a slotj in the scraper and screwed into the frame 9, as shown in dotted lines in Fig. 1.
Having thus described my device and its advantages, what I claim as my invention, and desire to secure by Letters Patent, is
1. In combination with the standard of a disk drill having an axle on each side thereof, of revolving disks mounted upon the axles, a curved inner scraper formed on the rear of the standard, with an opening between its lower end and the standard, to allow the discharge of earth that may get in between the disks, substantially as and for the purpose specified.
2. In combination with the curved arm of a disk-drill standard, of an adjustable inner or central curved scraper made to conform to the said arm and secured thereto, and leaving-an opening between its lower end and the standard, all constructed substantially as and for the purpose specified.
In a seed-drill, the combination with a grain-spout having an axle on each side thereof, of revolving diverging disks mounted thereon, and two chill-hardened projections cast on the sides of the lower end of the standard of the grain-spout, to correspond to the divergence of the disks, the disks impinging against the said projections and having their centers kept clean thereby, substantially as specified.
4. A casting for seed-drills having an axle on each side of its grain-spout, and a curved arm upon the rear of the grain-spout, a projecting eye attached to the said arm for securing a drag-chain thereto, and two lugs also attached to the said curved arm to afford means for securing a spring and pressrod for elevating and depressing the disks in operation, substantially as and for the pur= pose specified.
5. The combination in a disk drill,ofa grainspout, disks carried on opposite sides thereof, and a plurality of inner scrapers separated from each other by an interval to permit the discharge of earth between them, but conjointly acting on the entire inner surfaces of both the disks, substantially as described.
The combination in a disk drill of two disks, of a curved scraper'a'cting on the outer portion of the inner sides of the disks and a straight scraper acting on'the central portion of the innersides of the di'sks,the two scrapers being separated from each other by an interval to permit the discharge of earth between them, but conjointly acting on the entire inner surfaces of both the disks, substantially as described.
