Specification of Letters Patent.
Patented Feb. 10, 1914.
Application filed April 3, 1913. Serial No. 758,659.
To all to 7mm it may concern Be it known that I, OHAUNOEY E. BUNKER, J12, a citizen of the United States, residing at San Jacinto, in the county of Riverside and State of California, have invented certain new and useful Improvements in Land- Graders, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to new and useful improvements in land graders and more particularly to a wheelless alfalfa land grader. The object of the invention is to provide a grader having means whereby the scraper blade is disposed at a suflicient angle so that the dirt will readily slide upon the blade toward one end thereof.
Another object of the invention is to provide means for adjusting the scraper blade so that it will load itself in solid ground or will be adjusted to prevent the same from loading too heavy on soft ground.
Another object of the invention is to provide a land grader of the above character which will possess advantages in points of efliciency and durability, is inexpensive of manufacture and at the same time is simple in construction. and operation.
With the above and other objects in View, the invention consists in the novel features of construction and the combination and arrangement of parts to be hereinafter more fully described, pointed out in the claim and shown in the accompanying drawings, 1n which- Figure 1 is a top plan view of a road grader constructed in accordance with my invention. Fig. 2 is a rear elevation of one of the platforms; and Fig. 3 is a side elevation.
Referring more particularly to the drawings, 1 indicates the scraper blade, to the lower longitudinal edge of which is secured a metal strip 2, which prevents the steady wear upon the front edge of the scraper blade. Secured to the front of the scraper blade 1 and arranged in from each end thereof are the eyes 3, in which are mounted the rings 1, said rings being adapted for attachment to the whiffletrees whereby the scraper blade will be readily transported from place to place.
Secured to the rear of the scraper blade and arranged adjacent each end thereof are the plates 5, which may be secured to the scraper blade in any suitable manner and having each end thereof bent outwardly at right angles to the body portion to form the spaced ears 6. Pivotally mounted upon the ears 6 by means of the pins 7 are the boards 8, which form suitable platforms upon which the drivers are adapted to stand. The platforms 8 are pivotally secured to the plates 5 by means of the brace members 9, one of the ends of said brace members being provided with a plurality of openings 10 and secured upon opposite sides of the platform 8 by means of the screw bolts 11. The other ends of the brace members 9 are disposed upon a horizontal plane, as shown at 12, and pivot-ally secured to one of the ears 6 by means of the pins 7. Secured to the inner ends of the platforms 8 and arranged upon the under side thereof are the plates 13, which are substantially V-shaped in form. The intermediate portions of the plates 13 project beyond the inner ends of the platforms and are adapted to be pivotally secured to one of the ears 6 by the lower end of the pin 7 Rigidly secured to the lower face of the platforms 8 and arranged in longitudinal relation therewith are the guiding shoes 1 1, said guiding shoes having formed at their upper edge, the outwardly projecting cars 15, which are rigidly secured to the under face of the platforms by means of the pins 16. Rigidly secured to the under face of the platforms 8 at the rear ends thereof are the wear plates 17 which are adapted to engage with the surface of the earth when the rear ends of the platforms are pressed downwardly to prevent the earth wearing against the wooden surface of the platform.
It will be readily apparent from the above description that the platforms which are pivotally mounted upon the rear of the scraper blade 1 are adapted to swing upon their pivot and be disposed at an angle with respect to the scraper blade. The inner ends of the platforms 8 are provided at each corner thereof with the beveled portion 18, which is adapted to engage against the rear of the scrape-r blade when the platforms are disposed at an angle, as shown in Fig. 1.
It will be readily apparent that from an observation of Fig. 1, that the platforms 8 are arranged in parallel spaced relation and the scraper blade 1 disposed at an angle thereto. From this it will be seen that the shoes 14 which are pressed into the ground to guide the platforms 8 will hold the scraper blade from slipping around the earth which has been scraped up in front of the same, the shoes 14 holding the platforms 8 against lateral movement. From this it will be seen that when the shoes let are pressed into the earth by the weight of the driver upon the platforms 8, the platforms will be held against lateral movement, thus holding the scraper blade at the proper angle. It will also be apparent that the scraper blade 1 may be readily adjusted through the medium of the screw bolts 11 and the openings 10, which are formed in the brace members, the upper edge of the scraper blade being adjusted forwardly or rearwardly according to the condition of the earth upon which the scraper is to be used. If the ground is hard and solid, the upper edge of the blade is adjusted rearwardly so that the lower sharpened edge will engage within the ground more quickly while if the earth is soft, the upper edge of the blade is adjusted forwardly so that the lower sharpened edge of the same will not engage in the ground so readily.
From the above description taken inconnection with the accompanying drawings, it will be readily apparent that I have provided a simple and durable land grader, which is especially adapted for use upon alfalfa lands. It will also be apparent that the scraper blade can be readily guided and adjusted to various positions. It will also be apparent that the device is extremely simple in construction and can be manufactured at a comparatively low cost.
WVhile I have shown and described the preferred form of my invention, it will be obvious that various changes in the details of construction can be resorted to for successfully carrying my invention into practice without sacrificing any of the novel features or departing from the scope of the appended claim.
What I claim is In a device of the character described, the combination with a scraper blade, a plate rigidly secured to the rear face of the scraper blade, the ends of said plate being bent at right angles and arranged in vertical spaced relation, a platform disposed at the rear of the scraper blade, brace members having one of their ends secured to the longitudinal edges of the platform and the other ends mounted upon one of the outwardly projecting ends of the plate, a V- shaped plate secured to the under surface of the platform at the inner end thereof, said plate being pivotally motuited upon the lower end of the plate at the rear of the scraper blade, and a guiding shoe rigidly secured to the under surface of the platform.
In testimony whereof I hereunto affix my signature in the presence of tWo witnesses.
