DUMPING-SCRAPER ATTACHMENT FOR RIDGERS, 8w.

Application filed. January 12, 1918.

To all whom it may concern:

Be it known that I, J AMES M. 0001:, a citizen of the United States, residing at Anaheim, in the county of Orange and State of California, have invented new and useful Improvements in Dumping-Scraper Attachments for Ridgers, &c., of which the followin is a specification.

My object is to make a dumpmg scraper which may readily be attached to ridgers, cultivators and the like, and especially suited for irrigating loose soil.

My present invention is alternative to and an improvement upon my invention shown in a companion application for corner finishers for irrigation, filed October 29, 1917, Serial No. 199,088.

Figure 1 is a top plan View showing two of my dumping scraper attachments applled to a ridger.

Fig. 2 is a side elevation looking in the direction indicated by the arrow 2 in Fig. 1.

Fig. 3 is a rear elevation of one of the attachments as seen looking in the direction indicated by the arrow 3 in Figs. 1 and 2.

Fig. 4 is a fragmentary sectional detail on the line 44 of Fig. 3.

Fig. 5 is a view analogous to Fig. 1 and showing two dumping scraper attachments embodying the principles of my invention applied to a cultivator, the scrapers being farther apart and the foot lever rock shafts being longer than in Fig. 1.

Fig. 6 is a side elevation looking in the direction indicated by the arrow 6 in Fig. 5.

Fig. 7 is a fragmentary sectional detail on the line 7-7 of Figs. 4 and 8.

Fig. 8 is a sectlonal detail on the lines 8-8 of Figs. 4 and 7.

The details of the dumping scraper 1 are as'follows: The axles 2 and 3. are formed upon rectangular blocks 4 and 5, the ends of the blocks opposite the axles being slotted to form attaching plates 7 and 8. -The scraper blade frame 9 isinserted between the plates 7 and 8 of the blocks 4 and 5 and secured by bolts 10 so that the axles 2 and 3 are opposite each other and at the center of the frame 9. The edges of the frame 9 are notched to receive the blocks 4 and 5 which Specification of Letters Patent. Patented Sept. 17, 1918.

Serial No. 211,623.

are between the axles and the attaching plates, so that the shoulders of the axles are close to the edges of the frame 9. The bearings 11 and 12 are mounted upon the axles 2 and 3, the arms-13 and 14 extend upwardly from the bearings, and the draw- bars 15 and 16 extend forwardly from the upper ends of the arms 13 and 14. The supporting plate 17 has clown-turned ends 18 and 19 secured to the rear ends of the draw- bars 15 and 16 by rivets or bolts 20. The adjusting shanks 21 extend downwardly from the forward ends of the draw- bars 15 and 16.

The scraping blades 22 are attached across the ends of the frame 9 by bolts 23, the edges of the scraping blades extending beyond the ends of the frame. Triangular side wings 24 and 25 are secured against the outer-edge of the frame 9, said wings projecting in opposite directions, that is, the lower wing projects forwardly and the upper wing backwardly when the frame 9 is in a vertical position as in Fig. 2. Angle iron braces 26 are inserted inside of the wings against the front side of the frame and secured by rivets, so that the wings project forwardly at right angles from the frame when in scraping position and the lower edges 27 of the wings are out to curved lines concentric to the axle. Tire bands 28 and 29 each form substantially a half a circle with their ends turned inwardly, and these i'n-turned ends are rigidly fixed to the ends of the frame 9 so as to make segments of a band wheel between the scraping blades 22, so that when the scraper in contact with the ground is loaded to the desired extent or has reached the desired point it may dump and the band 28 or 29 will rotate the frame 9 upon the axles 2 and 3 to bring the other scraper into working position.

Posts 30 and 31 are rigidly fixed upon the upwardly. The lever 32 has a plurality of bolt holes 33 and the lever is mounted between the posts 30 and 31 and a bolt 34- is supporting plate 17 at its center and extend exerted to hold the roller 35 down in the track of the upper end of the frame. A. link 37 is pivotally connected to the forward upper end of the lever 32, a rock-shaft 38 is rotatably mounted upon the ridger 39 parallel with the axis of the scraper, and a crank arm 40 extends upwardly from one end of the rock-shaft 38 and is pivotal connected tothe forward end of the link 3 there being a plurality of bolt holes 41 in said link so as to adjust the length of the link. A footlever 42 extends upwardly from the other end of the rock-shaft 38 in position to be engaged by the right-hand foot of the operator sitting upon the seat 43. The shanks 21 are adjustably mounted in the clamps 44 carried by the cross-bar 45 rigidly mounted upon the ridger 39, said clamps being controlled by cap screws 46, so that by manipulating the cap screws the shanks 21 may be adjusted up and down in the clamps 44 to regulate the operating planes of the blades 22 relative to the lower edge 47 of the ridger.

When the foot-lever 42 is pressed forwardly the roller 35 is raised out of engagement with the frame 9 and forward movement of the ridger will cause the frame 9 to revolve upon its axis and dump the dirt which has been accumulated by the scraper and wing, the band 29 will engage the ground and continue to rotate the frame 9 until the other end of the frame is brought into operative position, then the roller 35 will hold the frame to continue the operation of accumulating another load of dirt.

The working position of the frame 9 may be slightly inclined forwardly and downwardly from the axis as shown in Fig. 2, or by moving the bolt 34 to the last hole 33 in the lever 32 the frame may be set to work practically straight up and down, and by moving the bolt into the front holes the inclination of the frame may be increased. This adjustment is desirable in working different kinds of soil. 1 The dumping scraper attachment 48 is identical in construction with the attachment 1 except that the attachments are made right and left to the extent that the wings 24 and 25 are upon the outside so that as the scrapers move forwardly the wings will hold the dirt from spreading outwardly andthe absence of wings at the insides of the frames 9 will allow the surplus of dirt to move inwardly toward the ridge formed by the ridger 39. These scraper wings 24 and 25 arranged upon the outer sides of the scrapers the links 37 and the rock-shafts 54 and 55 attachments 1 and 48, the only difference being that the links 52 and 53 are longer than are shorter. The bar 56 of. the cultivator frame earriesa series of clamps 44 for the purpose of mounting the cultivator shovels 57 shown in dotted lines in Fig. 6. When it is desired to apply the attachments the shovels 57 are removed from the clamps and the shanks 21 inserted into any desired ones of the clamps so as to locate the attachments the proper distance apart for the proposed work. The other clamps may be removed from the bar or may be secured upon the'bar in any suitable way. I

While in Fig. 1 I have shown two'attachments 1 and 48 involving two rock shafts 38 and two foot levers 42, it is obvious that either scraper is operative without the other; and while I have shown in Fig. 5 two attachments 50 and 51 and two rock shafts 54 and 55 and two foot levers 42 and 42, it is obvious that either attachment is operative without the other.

Various changes may be made in the details of construction without departing from the spirit of my invention as setup in the following claims. l

I claim:

1. A dumping scraper attachment for rldgers, cultivators and the like, comprising an axle, a blade frame rigidly mounted upon the axle, a wing extending from one side of the blade frame, a lever adjustably mounted 111 position to engage the blade frame to regulate the angle at which the blade frame engages the ground, and scraping blades upon the ends of the blade frame.

2. In a dumping scraper, a blade frame, blades upon the ends of the blade frame, blocks secured to the blade frame, axles formed upon the blocks, bearings upon the axles, arms extending. upwardly from the bearings, draw-bars extending horizontally from the upper ends of the arms, shanks extending downwardly from the draw-bars and adapted to be adjustably mounted in clamps, a supporting plate connecting the rear endsof the draw-bars, a lever pivotally mounted upon fi-the supporting plate and adapted to engage the upper end of-the blade frame and hold it in operative posi-' tion, means for'adjusting the lever backavardly and forwardly to adjust the angle and the like, and having rotating scraper of the blade frame, a rock-shaft, means for blades and Wings extending forwardly from mounting the rock-shaft, a link connecting the outer ends of the scraper blades so as to 10 the rock-shaft to the lever, and a foot-lever conduct the surplus dirt inwardly. 5 upon the rock-shaft. In testimony whereof I have signed my 8. Dumping scraper attachments adapted name to this specification. for connection to ridgers, cultivator frames JAMES M. COOK.
