Application filed April 27, 1914. Serial No. 884,697.

To all whom it may concern:

Be it known that I. JARED H. MOORE, a citizen of the United States, residing at Gilson, Knox county, Illinois, have invented a new and useful Grading and l illingll/Iachine, of which the following is a specification.

My invention relates particularly to apparatus adapted to cut off the tops of hills,

carry the dirt to the place where it is to be dumped whereby to fill a low place, and then automatically dump or discharge the load.

The principal objects of the invention may be summarily stated to be to generally improve the construction and to increase the capacity, utility and efiiciency of devices of this character. However, the objects and purposes of the invention will be-Inore specifically stated in the descriptions of the elements of which it is comprised and in the description of the operation.

It consists, substantially, in the improvements hereinafter described.

In the accompanying drawings, which illustrate my invention, Figure 1 is a side elevation, showing the complete machine as in operation, a hill top shown as partly graded down. a hollow partly filled, and a source of motive power; Fig. 2, a side elevation of one of the novel scrapers and the novel cable-clamp therefor and connectors therebetween; Fig. 3, a front elevation of the driving mechanism and other elements; Fig. 4, a fragniental sectional detail of either of the sheaves or pulleys hereinafter referred to: Fig. 5, a detail of one of said sheaves and a sectional view of the cable-clamp; Fig. (3, a side elevation of the driving mechanism and adjacent elements; Fig. 7, a detail of the shaft bearing; Fig. 8, a detail of the clutch mechanism; Fig. 9, a top plan of the structure shown in Fig. 3; and Fig. 10, a detail, partly broken away,.showing a portion of the main transverse shaft and parts connected therewith. 1

Coming now to a detailed description of the drawings, and referring thereto by distinguishing, reference characters, the same one of which is uniformly employed throughout the several views to designate the same part, 2' represents a maln frame comprising side sills 3, 4, end sills 5, 6, posts 7 and top pieces 8, 8'.

11, 11 designate brackets secured to a pair of posts 7. 12, 12 indicate strips secured on said brackets and supporting a pair of journal-bearings 13 in which a drive shaft 14 is mounted. 15 is the belt-wheel keyed on Saidshaft, and 16 is the driving belt' embracing said wheel and the belt-wheel 17 of an engine or other source of motive power 18.

19 designates an arch or truss on which the median portionvof the inner strip 12 is supported. 20,20 indicate bolts securingthe inner ,box l 3jto said strip and arch.

Securedon the inner end of the shaft 14 is a sprocket wheel 21 which is embraced by and drives a chain 22 which embraces also a PatentedFeb. 1, 1916. v

sprocket wheel 23 keyed on a shaft -24 the outer end of the section 27 being threaded into the adjacent knuckle (26) and, the outer end of the pipe 27 engaging the adjacent knuckle 26. The adjacent ends of the plpe sections are threaded and connected by an interiorly threaded annulus 28 having a flange 29.

30 indicates a'ring threaded onto threads cut on the outer face of the small end of the annulus, and is spaced therefrom to provide an annular way or channel in which seats a shift collar 31, the sleeve of Which is secured on a rock-bar 32 seated in bearings 33 secured on supporting plates 35.

34 designates a shlft-lever suitably secured on the rock-bar 32. with trunnions 36 on the collar 31 is a shiftyoke 37, the arm of which is'keyed on the shaft 32 to be actuated by the lever 34. (See Figs. 3 and 8).

38 designates a socket piece including a base-plate mortised into the sills, 5 and 6. 39 indicates an anti-friction hearing (as Babbitt metal) therein. 40 is a transmission shaft, its base seated to rotate in said bearing 39.

- 41 indicates a cap provided with an oilhole 42 through which oil-may be introduced into the concaved upper end of the bearing 39. V

43, is a set-screw for securing the cap in place.

The upper end of the shaft is supported in suitable bearings 81 at the central upper portion of the frame 2.

Fixed on the upper end of the shaft 40 Hingedly connected is a bevel gear-wheel 50 which is always in mesh with a pair of bevel pinions 51, 52, loosely mounted on the shaft 24. Each of these pinions is provided with a clutchmember 53, 54, respectively, whereby it may be thrown into or out of engagement with the adjacent or companion clutch-member 26 or 26- as the case may be, in the ordinary manner of such devices.

Fixed on and near the upper end of the shaft 40 is a sheave 55 having a peripheral channel 56 and a peripheral groove 57, the latter arranged just within the former. Also the lower flange of the sheave is much greater in circumference than is the upper one. less cable 58 which embraces also a similar sheave 59 rotatably mounted on. a shaft 60 secured in any preferred manner in the central portion of a jack or framework 61 ha"- ing placement at any suitable distance from the frame 2, as shown clearly in Fig. 1.

62, 62 designate U-shaped spring clamps through the ends of each of which a bolt 63 passes, and said bolt is engaged by a nut 64 which may be drawn down to V draw the clamp sides together to firmly bind the cable 58. As shown in Fig. 5, the arciform portions ofthe clamps seat and are bound (by the tension of the cable) firmly in the channel 56 when they come into contact with either sheave, and when they have passed therefrom, the cable at once drops into the groove 57 and is to quite an extent frictionally bound therein and driven thereby.

65 designates a link, 66 a ring, and 67a clevis hinged to the yoke 68 of a scraper 69.

It will be evident that there may be any desired number of scrapers and their securing means.

- In order to carry out the ends of myinvention in the most practical manner, it became necessary to devise a novel scraper which would automatically dump its load when it was drawn by the cable to the hollow. to be filled. For this purpose I have found the one shown best in Fig. 2 admirably adapted. The scraper body is preferably formed of a piece of sheet metal and comprises a bottom 71, bent-up sides 72, and beaded and overlapped rear end pieces 73, 73 secured together by rivets 74.

75, 75 designate apertured plates with which the yoke 68 is pivotally connected.

76. 76 designate runners the ends of both of which are securd t0 the sides and bottom of the scraper body.

77, 77 designate handles for convenience of operation in loading the scrapers.

It is to be noted that the end 73, 73 is so inclined as to form an obtuse angle with the bottom 71.

79, 79 designate curved guards, the ends of which are secured to the posts of the frames 2 and 61.

This sheave is embraced by an end- The operation As illustrated, the clutch members 26 and 53 are engaged, whereby the pinion ,51 is drivin the wheel 50 in the direction shown by t e arrows near the sheave in Fig. 3,'and, owing to the clutches 26 and 54 being disengaged, the pinion 52 is running as an idler. The movement ascribed is transmitted from the engine beltwheel 17 to the belt 16, thence through the belt-wheel- 15, shaft 14, sprocket wheel 21, chain 22, sprocket wheel 23 and shaft 24 to the clutch member 26. The wheel 50 will transmit motion to the vertically arranged shaft 40 and through it to the sheave 55, and the latter will impart motion to the cable 58. The clamps being secured on said cable will be drawn thereby and will carry with them, by means of the elements 63, 66, 67 and 68, the scrapers 69. Each clamp and link will be maintained, as it passes around each sheave, in the position shown in Fig. 5 or approximately so, to hold the scrapers 69 and yokes 68 well away from the sheaves and center shaft. If the cable is moving at a relatively high rate of speed, centrifugal force will tend to throw the scrapers outwardly when passingaround the sheaves,

and to prevent injury to either the scrapers or the frame-posts, I have provided the curved guards 79, against which the scrapers may strike. These guards may be of any suitable lengths. As is indicated in Fig. 3, the back or bottom'of the scraper is at all times when suspended from and supported entirely by the cable, carried in advance or directed toward the work. Therefore, when it strikes any obstruction, such as the proximate edge of a hill or ridge, the scraper will automatically right itself by being thrown thereby onto its bottom'and runners, in position to be grasped (by the handles 77) by the operatoras shown clearly in Fig. 1tosteady it as it progresses and scoops up its load. The load having been picked up, the operator may turn and grasp a scraper approaching from the opposite direction and then proceed in like manner to steady it while it is picking up its load. The'cable will continue to draw the scrapers in its own direction of travel, with the bottoms 71 and runners 76 sliding over the ground, in which position the scrapers will be steadily maintained until a decline is reached, whereupon the rear end of the scraper will begin to travel downwardly and inasmuch as the cable is taut and supports the front end of the scraper constantly at substantially the same height, said rear end will lie in a much lower horizontal plane than does the front end and it will therefore begin to automatically discharge its load, all of which will slide down the inclined rear end 73, 7 3' as the scrapers reach that point where they are entirely suspended from and by the cable.

1,iee,sae

It will be noted, as incidentally above stated. that the dirt may be simultaneously out and carried. from opposite sides of a hill, and that two hollows, on opposite sides thereof, may be simultaneously filled.

Fig. 1 is provided not to show the details of the device but to clearly illustrate the mode of operation thereof.

Ordinarily it will not be necessary to change the directionv of travel of the scrapers. However, under some conditions and circumstances, 1t does become desirable to make such change, and it may be accomplished by shifting the, lever 34 from the full to the dotted line position indicated in Fig. 3, thereby actuating the rock-bar 32 and arm 37 to move the shift collar 31 to the right, thereby disengaging the clutchmember 26 from its mate 53 and simultaneously throwing the clutch-member 26' into engagement with its mate 54, whereby the pinion 51' becomes an idler and the pinion 52 an active or drive pinion, and whereby the, direction of movement, of the bevel wheel 50 andsheave 55,a'nd thereby of the cable 58 are reversed.

If it be desired to remove the scrapers, or any of them, or to change their direction of placement relatively to thecablel, it may be quicklydone by merely removing the clevis 1n 80. I 'It will be evident that a plow or in fact .any one of the numerousv tools or implements'employed fora like purpose may be substituted for a scraper. Therefore, although thespecificword scraper is in the appended claims employed, I consider it as sential to the invention, broadly considered.

All this will be indicated in the claims hereof, wherein the omission of an element or the non-inclusion of reference to the detail features of the elements recited is intended to be a formal declaration of the fact that the omitted features or elements are not requisites of the invention covered by that claim.

I claim as new: 1. In combination, 'a horizontally arranged sheave having a peripheral channel and a peripheral groove therewithin, a sec ond sheave, meansfor driving one of said sheaves, a cable traversing said sheaves and riding in said groove, a cable-clamp engaging said cable and riding in said channel, a scraper, and means intermediate said clamp and scraperfor sustaining the latter.

2. In combination, a sheave having peripheral flanges one of which is greater in diameter than the other, said flanges providing a channel, and said sheave having an annular peripheral groove at the median portion of said channel, a second sheave, means for driving one of said sheaves, a cable traversing said sheaves and adapted to ride in said groove, a clamp grasping said cable and adapted to ride in said channel, a scraper and means for connecting said clamp and scraper.

3. In a device of the character described, a sheave having peripheral flanges one of which is greater in circumference than the other, said flanges providing a channel, a narrow peripheral groove within said channel, a cable adapted to travel in said groove, a cable-gripping clamp arranged to travel in said channel, a link connected with said clamp, its outer'end projecting over the edge of the larger flange, and a scraper connected with said link.

4. In a device of the class described, a sheave having a substantially U-shaped peripheral channel and a substantially U- shaped peripheral groove arranged interiorly thereof, means for driving said sheave, a cable, a second sheave traversed by said cable, a U-shaped clamp t'rictionally grasping said cable and its curved end conforming to and traversing said channel, said cable conforming to and fitting said groove, a link engaged by said clamp, and a tool suspended from said link.

5. In a grader, a frame including posts arranged to form a rectangular quadrangle, a vertically arranged transmission shaft located centrally thereof, means for driving said shaft continuously in one direction, a sheave on said shaft and driven thereby, an endless cable traversing said sheave, a second sheave traversed by said cable, and a tool carried by said cable and passing around said sheaves and intermediate the one first recited and said quadrangularly arranged frame-posts.

In testimony whereof, I hereunto afiix my signature this 22nd day of April, 1914.
