ROAD GRADER AND DITCHER.
o SPECIFICATION forming part of Letters Patent No. 460,919, dated October 6, 1891.
Application filed May 22, 1890. Renewed June 25, 1891. Serial No. 397.432. (N model.)
To all whom, it may concern:
Be it known that I, MORGAN E. LASHER, of
Champaign, in the county of Champaign and State of Illinois, have invented certain new and usefulImprovements in Road Graders and Ditchers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part. of
this specification, in whieh- Figure 1 is a side elevation ofinyimproved road grading and ditching machine. Fig. 2 is a top plan view thereof. Fig. 3 is a detail view of the opposite side of the machine. Figs. 4 and 5 are detail sectional views of the extensible gearing connections. Figs. 6 and 7 are detail views.
This invention isan improvement in ma 2o chines for grading and making roads; audits objects are to more effectually throw the earth to the center or side of the road, as may be desirable, and to prevent the scrapings or cut earth from accumulating in front of the 2 5 scraping-blade, so as to prevent the machine from working properly or to put great strain thereon, and whereby it will not be necessary to throw the scraper-blade up out of position in order to pass over such accumulations of 0 earth.
To this end the invention consists in an endless movable belt above and just in rear of the scraper-blade and provided with blades which will catch and drag the earth to one or the other ends of the scrapenblade and out of the way thereof.
The invention further consists in novel mechanism for driving and tensioning said belt and for vertically adjusting the scraper blade with its belt without disarranging the driving mechanism of the belt.
Another object is to enable side ditches, if desired, to be cut simultaneously with the grading of the road-bed and to this end Ipro vide a cutting-plow at one end of the scraperblade, but supported directly upon the main frame, and which is vertically adjustable also.
The invention further consists in certain other novel details of construction and com- 5 bination of parts, as are hereinafter clearly set forth, and concisely specified in the claims.
Referring to the drawings byletters, Adesignates the main frame of the machine, which is mounted on wheels, the rear axle being rigidly connected to the frame, while the front axle or truck is pivotally connected thereto, as in ordinary wagons, and to the latter is attached the draft-pole.
B is a vertical bar supported by transverse pieces I) b, attached to the front of the frame A and standing to one side of the front axle, and O is a similar bar, also supported on transverse pieces (2 0, attached to the main frame in line with and in rear of the bar B.
D represents a horizontal beam resting against the bars B O and loosely confined thereto by vertical straps E E, the ends of which are bolted to the respective bars B C, so that the beam D can be moved vertically.
F designates a Windlass, journaled in bear- 7o ings in or attached to the upper ends of the bars B O, and G G are ropes or chains suspending the beam D from the Windlass F. g is a rope attached to the Windlass near the bar 0, but wound thereon oppositely to the rope G, and it runs down under a sheave g, attached to the lower end of the bar 0, and then up and is secured near the lower edge of the beam D. By this means the rear end of the beam D is positively shifted up or down by revolving the Windlass. The beam D projects beyond the barB and the frontof frame A, and to its front end is adjustably attached a rolling colter or guide-wheel H, as shown, and also a friction-roller h, which 8 5 bears against the front face of the bar B and prevents backward movement of the beam, and a pin 7L, attached to the beam D at the opposite side of the bar B, prevents forward movement of the beam.
I designates a plow-standard, rigidly secured to the beam D about centrally thereof, and J designates a turn-plow of any suitable construction, fixed to said standard I, with its landside outermostand themold'board in- 5 ward, and adapted to turn the earth under the frame A as the machine is drawn forward.
f is a hand-wheel on the Windlass F for revolving the same, and any suitable devices we may be provided for locking the Windlass in any position.
J designates a horizontal beam or frame, suspended from the frame A and lying below the same and diagonally thereof between the front and rear axles, its forward end lying just behind the plow I, and its rear end extending to a point just in front and a little outside of the rear wheel at the opposite side of the machine.
jj are metallic straps attached to the upper and lower edges at the front end of the frame J and loosely conuectedto a rod K, which is secured to lugs or ears k, projecting'from or attached to the mold-board, standard, and
beam D, as shown, permitting the front end of the frame J to be vertically adjusted, if necessary.
The rear end of the frame J is suspended by a rod L, the upper end of which passes through a vertical bracket M, attached to the side of the frame A in rear of the crosspieces 0 c and is formed with teeth or a rack 1 engaged by a pinion m, fixed on a shaft m journaled in the bracket M and operated by a hand-wheel M, so that the rod L may be Any suitable devices may be used to lock the pinion and hold the rod when adjusted, and a friction vertically adjusted thereby.
roller m is arranged opposite the pinion m for rod L to bear against. This rod only sup-,
ports the frame J vertically.
N is a draft-rod, attached to the rear side and end of the frame J and bent upward and over the same and forward, its front end being loosely connected to a vertical staple or keeper n, attached to a block 0 on the ends of cross-pieces c opposite the bar 0.
O designates a vertical drum or pulleyjournaled in bearings formed in the straps j j at the forward end of the frame J, and P is another drum j ournaled in bearings or brackets o 0, attached to the rear end of the frame J similarly to the straps Q designates an endless carrier-belt set vertically or edgewise and running around the frame J, over the drums O P; and it can be tensioned by means of an idler R, mounted on a vertical portion of a bent rod 7', which has its ends journaled in lugs or brackets r secured to the rear side and about centrally of the frame J. a" is a continuation of said rod,formin g an arm by which it can be shifted, and R is a sector-plate secured to the rear edge of the frame J above the idler R, with the notches of which the arm a" can be engaged to lock the idler in any position desired. As illustrated, a textile belt is shown; but I prefer using endless-chain belting, as being more durable, and, in this case, the drums would be replaced by sprocket-wheels or have sprocket-teeth. The belt has a series of vertically arranged scrapers q q, secured to its outer face at intervals, which will drag anything thrown in contact therewith to one end of the frame according to the direction of revolution of the belt.
T designates a metallic scraping blade or grader suitably-secured to the front and lower edge of the frame J and curved as ordinary Scraper-blades are. Its upper edge pro ects slightly over the lower edge of the belt Q, but not to interfere therewith. The front end of the blade T projects just in rear of the moldboard of the plow J, and its rear end extends beyond the drum P.
U designates a guard-plate attached to the top front edge of the frame J and bentdown so as to overlie the top edge of the belt Q, thus the portion of the belt passing along the front of the scraper-frame J is kept vertical and its edges shielded from injury.
U designates a bar mounted transversely on the frame A and projecting to one side thereof above the rear end of the frame J, and V is a short shaft journaled in brackets u u, attached to the projecting end of said bar U and having a sheave V and a bevel-.
gear 1) on it. W is a short vertical shaft journaled in hearings in the end of the barU and in a box U, attached thereto and having a bevel-gear WV on its upper end engaging the gear v, as shown. To the lower end of the shaft V is connected by a universal joint w a short socket-piece w, and P is a short rod telescoping into socket-piece w and angular in cross-section, so that it will be rotated with and by said socket-piece w, and this rod P is connected bya universal jointp with the upv per end of the shaft p of the drum P. The universal joints are of any suitable construction.
Motion is transmitted to the shaft V by a belt X running over sheave V, and a sheave Y, attached to one of the rear wheels or other mechanism may be used for driving the belt Q without departing from the principal point of my invention.
Z is a platform on the frame A above the scraper-frame, and y z are the seats for the driver and operator.
In operation the machine is drawn forward and the operator, if it is desired to cut the ditch or use the plow, lowers the same by means of the windlass F, as described, thus lowering therewith the front end of the scraper-frame. He then adjusts the rear end of the frame, as desired, so that the surface of the road over which the machine passes will be properly graded. The movement of the machine will, through the mechanism described, impart a movement to the belt Q, causing it to revolve, so that its front portion travels away from the plow. As the earth is thrown up by the plow and accumulates in front of the scraper-blade,if it bank's up and rises above the blade, the pieces (1 on the belt will catch and drag it toward the rear end of the scraper-frame, discharging it there. This action enables the machine to produce better work and greatly relieves the draft strain and the wear andgtear on the scraper-frame.
The sliding and universal joint connections in the devices for transmitting motion to the scraper-belt allow the scraper-frame to be readily adjusted without hindering the action of the belt.
Having described my invention, what I claim as new, and desire to secure by Letters Patent thereon, is
1. In a road-grading machine, the combination, with the scraper-frame, of an endless belt arranged vertically edgewise and in a horizontal plane and mechanism for driving said belt, for the purpose and substantially as described.
