tions, and arrangements herein described and claimed. v

An object of my invention 1s to provide a scraper of a substantially cylindrical form ing the necessity of stopping the device, backwhich is mounted on wheels, and which is primarily designed to be drawn. by horses,

novel means being provided whereby `the scraper may be emptied of its contents rn a continuous movement forward, thus obviatl5 ing it up, and manuallyrightingpit, as isnec- 0 operator may rock essary with ordinary Scrapers.

A further object of my invention is to provide a wheeled scraper, wherein the bucket is pivotally mounted in such a manner that the the bucket -fromloading position into carrying position without the necessity of manually lifting the load as 1s the case with standard bucket Scrapers.-

A further object of my invention is to provide a wheeled scraper of compact form,

#wherein the ,supporting wheels are disposed within the cutting edge of the scraper.

A further obj ect of my invention is to provide a wheeled scraper which can not only carry a much larger load than can be carried by ordinary Scrapers, but can be operated readily by one person, Vices require two or more operators.

Other objects and advantages will `appear in the following specification, and the novel features of the invention Will be particularly pointed out in the appended claims.

My invention is illustrated 1n the accompanying drawing, forming part of this application, in whchy Figure 1 is a side elevation of the device,

Figure2 is a. plan View of the device,

Figure 3 is a section along the line 3-3`of Figure 2, Y

In carrying out'my invention, I provide a frame 1, preferably made of a channel iron ofthe shape shown in Figures 1 and 2. Apair while the ordinary de I will now describe the bucket, see Figure 1. The bucket 3 is formed of two sides 4, substantially circular in shape, but having flattened portions fora purpose hereinafter described. The sides 4 are reenforced by angle irons 5, which are composed of sides 6 and 7. The portions 6 are riveted to the sides 4 1n such a manner that the outer surface of the portions 7 will follow the contour of the sides 4. A sheet metal plate 8 conforms to the contour of the sides 4, between the points 9 and 10, and it is riveted to the-portions 7 of the angle irons 5. This' plate 8 forms the bottom 11 and the' backl 12 of the bucket. The b ack 12 has integral flanges'13 projecting at r1ght angles from the sides of the bucket.

The foremost portions of the sides 4 arev External bearings 19, having annular flanges 20, are placed against the outside of the plates 15, the flanges 20 projecting through the openings 18, and being rigidly held in place by bolts 21. The external bearings 19 are rotatablydisposed within the bearings-2. Each of the external-bearings 19 is provided with a bore 22 and a partition 23. The partition 23 has twothreaded o enings 24 and 25. An oil cup 24 is screwe into each of the openings 24.

The wheels 16 are placed in the spaces between the sides 4`and plates 15, the hubs 26 of the wheels being in alignment with the Aopenings 17 and 1-8. Hollow axles 27 are passed through the hubs 26 and into the bores 22 until they strike against the partition 23. Rods 28, threaded at both ends, are passed lthrough the hollow axles 27 andtheir outer ends are screwed into the openings 25.

A Internal bearings 29, each having an annular iiange 30, and a threaded opening 31 in the central portion thereof, are placed over the inner ends of the axles 27 until the threaded openings 31 are in position to receive the inner ends of the rods 28. The bearings 29 ing the bearings 29 tothe sides 4 the mounting of the wheels and bucket is completed.

i' the wheel axes, by pivots 34, as shown in Fig.

1. Said apron is adapted to swing fore and aft about said pivots into or out of operative relation to the front margins of the bucket, as will be evident from a eomparisonof Figs.

V1 and 3. The arrangement is such that when the parts are in loading, or in carrying position, the rear margin of the apron underlies the front margin of the bucket and supports it against independent rocking in a clockwise direction as viewed in Fig. 1, and, therefore, serves as a means for controlling its position. The apron may, however, be swung forward away from the bucket, as shown in Fig. 3, to

.permit the load to be discharged, as will be hereinafter explained. In loading the apron serves also as a scraper to take up the dirt, and direct it to the bucket, as indicated by the dotted lines in Fig.,1, said apron being provided with a front'cutting edge for that purpose. The apron 32 is moved into and out of engagement with the bucket by means aboutto be described. A rock shaft 34', having two levers 35 keyed thereto nearI its opposite ends, is rotatably mounted upon the lframe 1. A pair of links 36, adjacent to the sides of the bucket, are provided with integral pins 37 whichextend at right angles to the body of the links. The pins 37 are inserted in open- ,ings in the upturned portions 33, andthe free ends of the links 36 are pivotally connected to the tlevers 35. A hand lever 38 is keyed onto one end of the shaft 34', and the operator, by moving the hand lever 38 up or down, can disengage the'apron from the bucket, or lower the apron and the front of the bucket into scraping position.

The means for lowering the front of the bucket into loading position comprises bars 39 at opposite sides of the bucket, which are pivotally connected at one end to the levers 35 and their free ends formed into the shape of hooks 40. When the hand lever 38 is actuated in a manner so as to lower the apron, the swinging movement of the upper ends of the levers 35 will draw the bars 3 9 forwardly causing the hooks 40 to engage with lugs 41' which are upon the external bearings 19, and

thus rotate the bucket to lower its front edge in cooperation with the apron.

The device is provided with a tongue 42 which is rigidly secured to the frame 1 and to a channel iron 43, the channel iron V43 extending across the tongue and being riveted to the sides of the frame.` A bar 44, connected to the frame 1 by means of chains 45, and to the apron by means of links 46, is provided with a pair of sheaves 47. A chain or steel rope 48 is passed around the sheaves 47 in a manner shown in Figure 2 and its ends secured to single-trees 49. Thus the draft 1s 'applied directly to the apron.

rious parts of the device, the operation thereof may be readily understood. Figure 1 shows the carrying or transport position o f the scraper. It is primarily designed to be drawn by horses, but may of course be drawn by a tractor, and it is lowered to scraping or loading position, as indicated by dotted lines in Fig. 1,v by first freeing thehand lever 38 from the hook 52, and raising said lever tothe proper height. By raising t-he hand lever, the shaft 34 is rocked and the levers 35, together with the links 36, Iswing the apron 32 downwardly and rearwardly to loading position. As the levers 35 are actuated, the bars 39, which are pivotally secured thereto, engage with the lugs 41 at the hooked portions 40, and in this manner the bucket 3 is rocked forward until it isheld from further movement by the apron.A The parts being in the loading position shown by dotted lines in Fig. 1, the apron scrapes up the material to be loaded and delivers it to the bucket. The apparatus can/be made to cut at any desired depth merely by raising the hand lever 38 to a predetermined height and holding it there until the bucket is filled.

The bucket being filled, the hand lever 38 is lowered and placed under hook 52. This brings the bucket and apron up into carrying position again, as shown in full lines in Fig. 1, and they are held in this position'until the scraper reaches the place where the contents thereof are to be emptied. e

At this point, I wish to draw special attention to the diameter`of the sides 4. It will be observed that Athe diameter of the sides 4 .is

somewhat greater than that of the wheels 16, and that both sides 4 and wheels16 are .pivot-- ally mounted at their centers upon the same axls.- l

To emptyv the bucket, the hand lever 38 is pressed downwardly below the hook. This actuates the rock shaft 34 in lacounterclockwise direction as seen in Fig. 3, and moves the levers 35, and links 36, in a manner so as to swing the apron 32 forward and upward away from the bucket 3. This is usually done while the scraper is still lin motion. When the apron 32 is free from the bucket, as shown in Fig. 3, levers 53, which are pivotally mounted upon the inner surface of the plates l andare prbvided with lugs 54, will drop so that the lugs 54 will engage with ratchets 55. The ratchets are integral with the Wheels 16 and as the lugs '54 engage therewith, the bucket is forced to rotate with respect to the wheels until .it strikes the ground, as also shown in Fig. 3. At this point, the carriage or supporting structure starts to ride upon the bucket, with the wheels clear of the ground, and as the scraper is drawn. forward, because of its engagement witlrthe ground, the bucket is revolved, further; until it makes a complete turn, thus emptying its contents. However, before the bucket makes a complete revolution, the hand lever 38 is released and allowed to assume its normal position again in engagement with the hook V52. 'lhe purpose of this is to lower the apron 32 into its normal position. Therefore, when the bucket has revolved far enough to empty its load, the wheels 16 will again engage with the ground and the apron 32 will catch the bucket and retain it in normal position.

Drawing attention again to the levers 53,

' it will be observed that the forward free ends 56 thereof are bent outwardly at right angles Yto the length of the levers. Vhen the appathe contents thereof. When the bucket comcome in contact with the ground. -Atthispletes its revolution, the projections 57 ofthe bars 39 which have regained their normal position, will catch the ends 56 and hold the levers 53 in a position so that the lugs 54 willv not 'engage with the ratchets 55. As vthe bucket turns over the free ends of the levers 53 are held against droppin down into engagement With the ground. 4y stop lugs 58 extending inwardly from the upper edges of the side plates 15 in position to hold the levers. 53 in proximity to the ratchet wheels 55.

lt. will be observed that the bucket has a load-receiving edge, which is adapted to be lowered with the apron, and to receive the Said ucket in loading and in carrying posimaterial to be loadedas it is cut from'th ground by the apron. When the bucket is again brought back to normal or transport position, the vapron swung 'free' from the bucket, and the latter rotated, the load-receiving edge is the first portion ofthe bucket to point, as the forward movement continues, the wheels are swung free from` the ground, and the bucket is rotated into dumping position. e
