fApplioation filed May L 1907. Serial lilo. 371,348- l T alliwlom "it may concern:
Be it known that I, CnAnLns lll. GUNN, a citizen of the United States, residing at Mai Tsville, in the county of Yuba and State of alifornia, vhave invented certain new and useful Improvements i'n 4Dredgers and Scrapers; and l do declare the following to be a full, clear, and exact description of the Same such as will enable others skilled in the art to which it appertains to niale and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon., which forni a part of this speciiication.
This inventionrelates to improvements .in
dredging and scraping machines, the object of the invention being to produce such a mafA chine as will automatical r scrape the earth and advance the saine to lan elevating con-` veyer, dump the same onto said conveyer, lmrnediately rise clear of such convever, and
,return to a sera ing position again, all of said movement, ine uding themoveinent of the conveyer, being simultaneous and coperative and actuated bv. a single actuating IIneans. This main object and many minor ores I accomplish by means of drive wheels having pitmen pivotally secur'ed thereto, means for oscillating or vibrating said pitmen, aseraper arrangedin operative connection with said pitmen, and an elevating conveyer operated by the movement of said drive pulleys and arranged in operative connection with said scraper, also by such other and further construction as will appear by a perusal of the following specification and claims.
In the drawings similar characters of reference indicate correspondingl parts in the 'several views.
Figure 1 is a side elevation of thecoinplete device. Fig. 2 is a longitudinal section of the device. Fig. 3 is a sectional view taken on aline a; x of Fig. 1. Fig. 4 is a front elevation of a serrated spading bar.
.Referring more particularly to the char acters of reference on the drawings 1 designates base beams., Across the under sides of the said beams 1 near the front thereof is a .cross beam 2 in the center of which is journaled a. roller 3.
1 are inclined beams secured to the rear of the beams 1 and supporting at their upper ends inclined beams 5, said beams 5 being secured to the beams 1 at their lower ends.
Secured to the beams e is a cross beam 6 'at the ends of. which beam are j ournaled supporting wheels 7. Secured across the beams 1 near the rear thereof isa platform 8 on which. is stationed an engine 9, the shaft 10 from the crank; having a worin' gear 11 secured thereto aid interineshingwith a screw gear 12 oir-a shaft 13 journaled on supports 111-, on the ends of which shaft 13 are secured sheave pulleys 15.; Cables or straps 16 connect the pulleys with larger sheave pulleys 17 secured on a shaft 1S, which shaft 18 is ournaled across the top ends ofthe bea-ins Secured to the shaft 18 between the beams 5 is a roller 19.-
2O and 21 are suitable cross braces and cross beams joining the beams 5. Journaled between the beams 5 at their lower ends is a roller 22. 22 is a conveyer belt 23, the same" resting on concave rollers 24 disposed between the beams 5, all fora purpose as will appear. Se cured to the sides of the beams 5 near the lower ends thereof' are metal side plates 24 and upward from said plates 25 are beams 26 secured to the beams 5 by means of angle irons 27, said beams extending slightly over the 'edges of the conveyer belt 23. Secured between the lower ends of the beams 5 is an inclined plate 28, the same extending 'u over the belt 23. Tied to the beams 1 anc, 5 by U-shaped ties 29 are slightly inclined beams 30, the same being tied at the top end by means.
of cross beam 31 and cross rod 32. J ournaled between the ,beams above the beams 5 is a roller 33'. Secured in the rims of the pulslevs 17 are wrist pins 34 on which are pivotally mounted pitinen 35, said pitmen extending along side of and beyond the beams 30. Tied vto the outer ends ofthe pitmen l35 are .cross beams 36 and tied to the said pitmen 35 to the rear of the beams 30 are higher cross beams 3' Tied to the beams 36 and 37 are longitudinal beams 38 provided with bottom iron rails 88 a, which beams 38 extend over the roller 33 and between the beams 30. On the outer ends of the beams 38 is secured a scraper 39 having a removable blade 40 and strengthening chains 411 connecting the lower part of said scraper to the beams 38. Held outward from the rear of said scraper is a serrated spading bar 4.2 for the urpose as will a pear. To the rear of the rol er 19 is secured a iopper 43 having side chutes 4i.v
Tn practice the pitmen 35 are secured t0 the pulleys 17 at such points andWill prov duce the `following motion z-Fresuining the i pitmen to be in their' lowest position as i yet admirably adaptable for the purpose for v shown at a in the drawings, the beams 38 are which it is designed.
lresting on the rollers 33.. The pulleys 17 revolve rearward, thus advancing and raising the pitmen 35 to a point as at b, thusraising the beams 38 from the roller 33 and thus causing the whole Weight of the pitmen and Thus it will be seen that thelmotion E their parts to fall on the scraper 39. When this position is reached the scraper 39 is adapted tol engage with the earth. The pitmen are then, by rotation of the pulleys 17, pulled backward and upward to a point as at c, which action pulls the sera er alon the ground up to the incline 28, f ing the owl of the scraper with dirt and depositing it on the conveyer 23. The rotation of the 'pulleys 17 then pull the pitmen to the position a, thus causin the beams 38 to rest on the roller 33, w ich action lifts the scraper 39 immediately upward ready for another drive.
'ust described is most advantageous in tiat the most possible weight is thrown on the scraper 39 just as it is to perform its scraping i'unction, thus making the same more eiiective. Then when its function is performed it immediatelyrises clear of the machine ready for l another operation.
The urpose of having the pitmen extend outside of the beams 30 and the beams 38 inside is to permit a freedem of motion to the pitmen and a restricted motion to the beams 38 by the roller 33 as described. The member 33 by means of the members 36-37 and 38 holds the pitmen in suspension, thus restricting the movementl thereof to cause the scraper 39 to properly engage with the plate 28. The pulleys'. 17 and wrist pinsA 34 perform the functions of cranks in oscillating and reciprocating the pitmen 35, hence in the claims I have employed this designation in claiming these elements.
The serrated. bar 42 extending to the rear of the scraper 39 tends to spade and loosen the earth while the scraper is performing its functions, thus rendering it more easily handled by said scraper. As the earth is deposited upon the elt 23 it is lcoiiveyed up- -ward, the oval shaped rollers 24 and the side member 25 and 26 iorm 'ing a trough and holding 'the earth in the center of said belt, thus preventing lit from falling oil the edges. As the earth reaches the top oi the belt 23 it is deposited in the hopper 43 and then distrib-- uted through the chutes 44 to any desired oint. By reason of the binding irons 29 the beams land their parts may be moved to any desired position. The roller 3 permits the front of the machine to be easily turned inany desired direction.
Thus it will be -seen that I have produced a device which is invaluable for dredging and scraping and particularly for ditch making and grading, the Whole' machine and the movement thereof being extremely simple While in this specification I have set forth in detail the present and `preferred construction of my invention, still in practice many small deviatins therefrom may be resorted to in practice without departing froml the Vspirit of my invention.
Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is 1- l. In a device of the character described an inclined conveyer, drive pulleys journaled at the top thereof, means for rotating said pulleys, pitmen pivotally secured to the rims ci said pulleys, a scraping means in operative connection with said pitmen, and means whereby oscillating movement imparted to said pitmen will cause said scraper to cut and draw earth to said conveyer, as specified.
