CLEANER FOR DISK DRILLS- SPECIFICATION forming part of Letters Patent N0. 756,697, dated April 5, 1904.
Application file-C September 15, 1903. Serial 110, 173,243. (No model.)
To all whmn it may concern.-
Be it known that I, OCTAVE A. POIRIER, of Gladstone, county of Ramsey, State of Minnesota, have invented certain new and useful Improvements in Cleaners for Disk Drills, of which the following is a specification.
In the operation of double-disk drills it is customary to provide cleaning devices arranged to yieldingly bear upon the outer surfaces of the disks and scrape OK the dirt that accumulates on said surfaces as the machine is moved over the field. These cleaning devices have usually been mounted on pivoted levers that are connected by a coil-spring which when one cleaner is moved away from the surface of the disk by the accumulated dirt thereon will exert a corresponding force on the opposite cleaner to press it against its disk. This last-named disk may have a perfectly clean surface, and its cleaner being pressed firmly thereon will greatly increase the friction and the draft of the machine and frequently stop the disk from turning.
The object of my invention is to provide a yielding connection between the cleaner or scraper levers Which will allow one cleaner to be moved away from its disk by the pressure of the dirt thereon without in any way affecting the other cleaner or increasing its pressure on the surface of its disk.
The invention consists generally in various constructions and combinations, all as hereinafter described, and particularly pointed out in the claims.
In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of a portion of a double disk and boot with my invention applied thereto. Fig. 2 is a section on the line 2 z of Fig. 1. Fig. 3 is a section on the line y y of Fig. 1.
In the drawings, 2 represents a grain-drill boot, and 3 the drill-disks mounted thereon. t represents levers having studs 5 to enter sockets 6 on said boots and pivotally support said levers thereon. I prefer to provide flanges 6 on said levers adapted to enter recesses 7 in the boot and prevent the accidental disengagement of the studs 5 from their sockets. WVhen, however, the levers are swung around to a reverse position, the flanges will pass out accumulates thereon while the machine is in use.
9 is a spring loosely'coiled around the vertical spout portion of the boot 2 and having ends 10, connected with the levers I. I This spring has a sufiicient number of coils around the spout portion of the boot to exert a yielding tension on the levers to hold the scraperplates against the surfaces of the disks, and each lever can swing on its pivot without in any way affecting the opposite lever. Consequently if mud accumulates on a disk, either through using the machine in wet ground or where dirt has been allowed to collect and dry on the disk-surface, and one of the cleaners should be pressed away from the disk-surface the opposite cleaner, which perhaps is operating on an entirely clean surface, will not be in the slightest degree affected, but will exert the same yielding pressure on the disk-surface that it would if the corresponding surface of the other disk were entirely clean. I am thus able to reduce considerably the draft of a machine and obviate entirely the danger of a perfectly-clean-surfaced disk being held by its cleaner against turning simply because the other disk is muddy and its cleaner engaged in the operation of removing the same.
I claim as my invention 1. In a double-disk drill, the combination, with a boot and the disks mounted thereon, of pivoted levers, cleaners carried by said levers and arranged to bear respectively uponthe corresponding surfaces of said disks, and a spring device arranged to yieldingly hold said cleaners against said surfaces and allow one cleaner to be moved away from its disk-surface without increasing the pressure of the other cleaner upon its disk-surface.
2. In a double-disk drill, the combination,
with a boot and the disks mounted thereon, of
pivoted levers, cleaner-plates carried by said levers and arranged to bear respectively upon the outer surfaces of said disks, and means yieldingly connecting said levers and permitting movement of either cleaner-plate away from its disk-surface Without aflecting the pressure of the other cleaner-plate upon its disk-surface.
3. In a double-disk drill, the combination, With a boot and the disks mounted thereon, of pivoted levers, cleaners carried by said levers IO and arranged to bear-respectively upon the outer surfaces of said disks, and a spring desaid levers, for the purpose specified.
In Witness whereof I have hereunto set my 5 hand this 7th day of September, 1903.
OCTAVE A. POIRIER. In presence of RICHARD PAUL, S. V. GRIFFIN.
