To all whom it man concern:
Be it known that I, George E. Richardson, of Pomona, in the county of Manistee and State of Michigan, have invented a new 5 and usefullmprovementin Scrapers, of which the following is a full, clear, and exact description.
The object of my invention is to provide a scraper so constructed that the scoop may be io given any desired forward inclination, and whereby also the scoop may be elevated at the front and depressed at the rear in order that the load may be dumped from its rear end, thereby greatly facilitating work on 15 roads, since the scraper may be backed up wherever the load is to be deposited and the load dropped without requiring, in many instances, the rehandling of the load by shovels, and to that end the scoop is provided 20 with a removable back gate.
A further object of the invention is to construct the machine in an exceedingly light yet durable and economic manner.
The invention consists in the novel con25 struction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.
Reference is to be had to the accompanyingdrawings, forming a part of this specification, 30 in which similar characters of reference indicate corresponding parts in all the figures.
Figure 1 is a plan view of the scraper. Fig. 2 is a side elevation, the axle being in section outside of the frame. Fig. 3 is a rear eleva35 tion of the scraper, and Fig. 4 is a vertical longitudinal section taken practically on the line 1 4 of Fig. 1.
In carrying out the invention the axle A is provided with two loosely-mounted driv40 ing-wheels 10, one at each end. The tongue A'is either secured to the axle or to a frame B, which is attached to the said axle and extends forwardly and rearwardly therefrom, preferably a greater distance in a forwardly 45 than in a rearwardly direction. The frame B is of substantially skeleton construction, and in the said frame near the front a shaft 11 is journaled, being provided at each end, which extends beyond the frame, with a pin50 ion 12, and at each side of the center of the shaft, within the frame, ratchet-wheels are secured thereon, (designated, respectively, as 13 and 14, being best shown in Fig. 1.) A leveils is pivoted on the shaft 11, the lower end being bifurcated, so as to straddle the ratchet- 55 wheel 14, and this lever is provided with a thumb-latch 16, avhich at its lower end may be brought in engagement with the teeth of the ratchet-wheel 14. The teeth jof the tavo ratchet-avheels 13 and 14 are inclined in op- 60 posite directions, and the ratehet-avheel 13 is straddled by the bifurcated end of a lever 17, also provided with a thumb-latch 18, adapted for engagement with the aforesaid ratehetavheel, so that by moving the lever IS the 65 shaft may be turned in one direction and maj<sup>r </sup>be movedin the opposite direction by manipulating the opposing- lever 17. The shaft may be held, hoavever it is turned, through the medium of a third ratchet-wheel 19, secured 70 on the shaft near one end and engaged by a pawl 20, pia-oted to the frame, and which may be operated by the foot of the driver.
At the rear of the frame B a shaft 21 is journaled, which extends beyond the sides of the 75 frame, and at each end of the said shaft a pinion 22 issecured. The shaft is turned through the medium of a lever 23, avhich is secured on the shaft in any approved manner, and the said shaft is further provided with a ratchet- 80 avheel 24, avhich is engaged by a pawl 25, the said pawl being pivoted on the axle A, and it is adapted to be operated by the foot of the operator or driver.
A grooved pulley 26 is secured, ordinarily, 85 at the central portion of the rear shaft 21, and a chain 27, which is attached to the footlever 28, located on the axle or on a near-by support, is carried downward over the aforesaid grooved pulley. The driver’s seat 28<sup>a</sup> is 90 so placed that all of the levers will be within easy reach of its occupant.
Near the forward end of the scraper C a rack 29 is secured at each side, and these racks are carried upavard to an engagement 95 avith guides 30, located on the frame B, and the toothed surfaces of the aforesaid racks are brought in engagement with the pinions 12 on the forward shaft 11. Correspondingracks 31 are secured to the sides of the rear 100 portion of the scraper, and these rear racks are carried upavard through guides 32 to an engagement with the pinions 22 on the rear shaft 21.

Slideways 33 are erected at each side of the rear portion of the scraper, and in the said slideways a gate 34 is loosely mounted, being adapted to close the rear end of the said 5 scraper, and this gate at its central portion is attached to the chain 27, connected with the foot-lever 28.
By manipulating one or the other of the forward levers 15 and 17 the forward end of io the scraper may be lowered to working position, as shown in Fig. 2, or it may be raised entirely from the ground, as shown in Fig. 3; and after the scraper has received its load the lever 17, for example, may be manipu15 lated to raise the forward end of the scraper and the rear lever 23 operated to drop the back end, as shown in Fig. 4; and when the dumping-ground is reached the foot-lever 28 is pressed forward, which will carry the end20 gate 34 upward from the rear of the scraper, permitting the load to be discharged therefrom, since the scraper will have a rearward and a downward inclination; and it is evident that by means of the forward pawl and 25 ratchet 19 and 20 and the rear pawl and ratchet 25 and 24 the scraper may be held in any position to which it may be necessary to adjust it.
