Specification of Letters Patent.
Patented Oct. 24, 19115.
Application filed July 23, 1904. Serial No. 217,843.
T a/ZZ wiz/0m, it 71mm/ concern.-
Be it known that we, NATHANIEL Gr. ROBIN- soN, JUSTIN A. ROBINSON, and AUGUs'r H. MEIER, citizens of the United States, residing at VVoolstocl, in the county of Wright and State of Iowa, have invented a new and useful Road-Grader. of which the following is a specification.
r1`he object of our invention is to provide road-grader in which a plow is arranged to deposit the loosened earth on a rotary carrier.
A further object of our invention is to provide a road-grader in which a plow is arranged to deposit the loosened earth on a rotary carrier, the rotary carrier being provided with a scraper for removing` the earth therefrom.
A further object of ourinventiou is to provide a road-grader in which a plow and rotary carrier or elevator` are arranged on a wheeled frame, the plow and rotary carrier bcing adjustable altitudinally andthe rotary carrier being provided with a scraper for removing the earth therefrom, the scraper being adjustable transversely relative to the machine for depositing the earth at different poinfs transversely of the road or place being graded or worked.
Our invention consists in the arrangement and combination of a plow, a rotating carrier, a frame and wheeled supports for the frame, as hereinafter more fully set forth, pointed outin our claims, and illustrated in the accompanying drawings, in which- Figure 1 is a plan of the complete machine. Fig. 2 is a side elevation of the complete inachine. Fig. 3 is a front elevation of the complete machine. Fig. 4 is a view illustrating the means for tilting` the rotary carrier. Fig. 5 is a view illustrating the means for raising and lowering the front end of the machineframe. Fig. 6 is a detail elevation of the means for raising and lowering the plow. Fig. 7 is a view, partly in section, showing the construction of the trucks on which the frame is mounted. Fig, 8 is a view illustrating the means for manually turning the rear truck.
Referring to the accompanying drawings, the reference-numeral 10 is used to designate the frame of the machine, and 11 a connecting rod or reach between trucks 12 and 13.
14 and 15 indicate caster-wheels designed to support that portion of the frame of the machine which carries the drivers seat 16, operators seat 17, and the plow 18 and its operative parts. y
A rotary carrier or elevator 19 is mounted on the connecting-rod 11, and a scraper 2O is carried thereby.
The plow 18 is carried by a vertically-movable bar 21. A lever 22, pivoted to the machineframe, having' an extension 23 pivotally fixed to the bar 21, is designed to move said bar.
A spring-pawl 24 is carried by the lever and coacts with a rack 25 on the machine-frame to hold the bar 21 and plow 18 at a raised or lowered position-or at intermediate points between the upper and lower limits of movement. A lever 26, pivoted to the plow 18, is provided and arranged to hold the plow in a horizontal plane at all times.
'.lhe carrier 19 is substantially circular in plan and is hung by radially-disposed arms 27 from a collar 28, embracing a shaft 29, the shaft 29 being supported by the connectingrod 11 and arranged to be tilted by the lever 30 and lever 31, the lever 31 being' fixed to the machine-frame. A contractile coil-spring 32 is fixed at one end to the lever 30 and at its other end to the lever 31 and is arranged to hold the carrier elevated when the levers 30 and 31 are in substantially parallel plane.
A concentric guard 33 is provided and is carried by arms 34 and is arranged in a position relative to the plow for retaining the earth on the rotary carrier during a portion of its travel.
A scraper 20 is arranged to take the earth from the rotary carrier and is carried by an arm 35, pivotally mounted on the shaft 29. A rod 35 and lever 36, paw] 37 on the lever 36, and a rack 38 on the machine-frame coact to hold the scraper at different points on the rotary carrier to deposit the earth from the scraper at different points transversely of the road.
The trucks l2 and 13 are substantially of the same construction, each having a non-rotating axle 39, provided with a socket 40, adapted to receive a ball-ended bar 41. The bar 41 is square in cross-section at 42 to prevent movement in a clamp 43, fixed to the machineframe, and set-screws 44 secure the clamp at various desired positions on the bar 41. To the :front truck 12 is fixed a tongue 45 for guiding the machine.
r1`he rear truck 13 has a manually-operative IOO IOS
To add further vertical adjustment to the plow 18, a lever 49 is employed. rIhis lever is pivoted to a sleeve 50 on the stem 51 of the caster 14 and to an angle-iron 52 on the front of the machine-frame, and a chain 53, fixed to the lever 49 and engaging a hook on the machine-frame, holds the lever in the desired position.
An equalizer of any desired construction 54 is fixed to the front end of the machine` to which draft-animals may be attached.
In practical operation, assuming' the machine to be in a working position on a place to be graded, it is obvious that earth loosened by the plow will be turned by the plowshare onto the rotating carrier and held thereon by the guard during a portion ol' its travel on the carrier and that the scraper will remove the earth from the carrier, and it is to be noted that any desired depth of cut may be made by the plow, and the scraper is arranged to deposit the earth at different points on the road transversely relative to the machine. It is to be noted, further, that the carrier has no mechanical means for its movement, it being driven solely by the earth as supplied thereto by the plow.
Having thus described our invention, what we claim as new therein, and desire to secure by Letters Patent of the United States therefor, is-
1. In a road-grader, a rectangular frame, wheeled trucks for supporting one side of the frame, casters for supporting the other side of the frame, and means for vertically adjusting the frame relative to the trucks and casters.
