UNITED STATES ATENT OFFICE.
THOMAS MAXON, OF DAYTON, OHIO, ASSIGNOR OF ONE-HALF TO EDYVARD O. BOYER, OF SAME PLACE.
DISK HARROW AND CULTIVATOR.
SPECIFICATION forming part of Letters Patent No. 417,572, dated December 17, 1889.
, Application filed January 17, 1889. Serial No, 296,578. (No model.)
.To all whom it 17mg concern;
Be it known that I, THOMAS MAXON, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have'invented certain new and useful Improvementsin Disk Harrows and Cultivators, of which the following is a specification, reference being had therein to the accompanying drawings, in which Figure 1 represents a bottom view of my improved harrow and cultivator; Fig. 2, a vertical longitudinal sectional view; Fig. 3, a detail view of one of the automatic scrapers; and Fig. 4, a rear view of one of the diskgangs, showing the operation of the scrapers.
The invention relates to certain improvements upon that class of harrows patented to me on the 16th day of October, 1888, wherein two opposing gangs of rotary concavo-convex disks are arranged on opposite sides of the tongue and connected thereto in a suitable manner; and it has for its special object the provision of improved means for shifting the angle of the said gangs with respect to the line of draft, and also to provide improved devices for cleaning or scraping the concave sides of the disks, as will befully hereinafter explained.-
In the drawings annexed, the letter A designates the tongue or draft-pole, provided at or near its rear end with a rigid cross-beam B; O O, the gang-beams, pivdtally connected at their inner ends to the ends of the stationary beam B; D D, the gangs journaled in suitable divided boxes or bearings bolted to the under side of the said gang-beams O, and E an independent beveled disk inserted between the inner ends of the gangs to receive the end-thrusts thereof and cause them to work in unison. These parts of my machine are fully described in my former patent, (above mentioned,) and I therefore do not deem a further explanation of them in this specification necessary.
Secured upon the tongue is a segmentplate a, and pivotally supported upon this segment-plate is a lever 19, this lever being provided with a suitable spring-actuated bolt or catch to engage suitable teeth or serrations formed on the said segment and hold the lever in any desired position. Connecting the lower end of this lever to a yoke c, embracing and pivoted to the tongue, is a pivotal link d, as shown in Fig. 2. This yoke or frame 0 is composed of two vertical bars connected together above and below the tongue by means of horizontal bars, the horizontal pivotal bolt being passed through the tongue or pole. Pivotally connected to this yoke at a suitable point below its pivotal point are the inner draft or shifting rods 6 e, the rear ends of which pivotally connect, respectively, with the inner bearings of the gangs. Pivotally connected to the yoke at a suitable point above its pivot are the forward ends of the outer draft or shifting rods c e, the rear ends of the rods being pivotally connected to the outer bearings of the respective gangshafts. By this construction it will be observed that when the lever 12 is moved in a forward direction the inner draft-rods e e will also be pulled forward and the outer draftrods e e forced rearwardly, and vice versa. By this arrangement the relative angle of the gangs may be quickly and easily changed, whether the harrow is in operation or not.
The scrapers f consist each of a plate or blade provided with a vertical slot or opening f and a rounded upper end f. They are pivotally connected to a shifting-bar g, which passes through the slots f and is supported in suitable bearings or brackets h, secured to thegang-beams. The upper rounded ends of the scrapers fit in concave notches or sockets formed in the under side of metallic blocks or plates 2', fastened to the lower side of the gangbeams. Pivotally connected to the shiftingbars and pivotally supported upon the gangbeams are the operating-levers 7a, which extend up within easy reach of the drivers seat. The cutting or scraping edges of the scrapers when in operative position bear yieldingly upon theconcave faces of the disks, the weight of the levers serving to produce this yielding pressure, as shown in full lines in Fig. 4. When the levers are brought up to a vertical position, both the shifting-bars are moved in an outward direction, thus drawing the scrapers away from the disks, as shown in dotted lines in Fig. 4, stops Z Z on the gang-beams IOO serving to restrict the movement of the levers. The scrapers are held in this latter rounded notches in the wearing-plates, and an operating-lever, substantially as herein 3 set forth.
2. The combination of a gang beain and shaft provided with disks, a sliding bar,
mounted in hangers'se'cur'e'd to the gang-beam,
an operating-lever pivoted .upon the gangb'e'ain and connected to the sliding bar-,a stop Zupon the gang-beam to restrict the movement of the said lever, metal bearing-blocks 'L', secured upon the gang-beam and provided with concave notches in their under side, scrapers f, provided with longitudinal slots f and rounded upper ends f", said sliding rod being passed through and pivoted in the slots f and the upper rounded ends f resting in the rounded notches'in the bearingblocks 2', the Weight of the operating-lever being adapted to hold the scrapers yieldingly against the disks, as and for the purpose described.
In testimony whereof I affix my signature in presence of two Witnesses. H
