Fi@7,@' 1-4- is ,t fr,,igmentary detail perspeetive . the alitomatic clute@ operating mech.55 anism. Fig. 15 is a frltgmentary dethil of the scraper. The ditch digger ,tnd grader -is inounted ol- constructed upon a motor vehicle comprising@a rear axle 1, a front ,txle 2, a framc 60 3 mounted- Lipon the axles 1 and 2, wheels 4 upon the rear. axle, wheels 5 upon the front axle, and an engine 6 upon the forward end of the frame 3. Sills 7 and 8 are mounted below the txles 6,5 I and 2 inside of the wheels 4 and 5 and rigidly secured to the side bars 9 and 10 of t e ame 3 by races 11. The sills and 8 extend a considerable distance back of_the rear end of the frame 3 and a considerable 70 distance in front of the forward end of the frame 3, and the sills 7 and 8 are just above the oro,und. An ektension frame 12 is constructed upon the forward ends of the sills '7 tnd 8 substantially on a level with the 75 frame 3. A winding drum 13 is moi-inted transi-ei-sely and liorizontally at the forwtrd end of the' frame 12. The winding dr-Lim 13 is mounted loosely -Lipon a shaft 14 and is con- 80 trolled by ,t clutch construction 15. A sh,,tft 16 is MoLinted in the frame 12 behind the shaft 1.4 -,ind connected to the shaft.14 by sl)ur ge,,trs 17 and 18. The shaft 19 is coilnectecl to the forw,,Lrd end of the engine 85 shaft 20 by a coupling 21, tnd ,L bevel pinion 22 is mounted upon the forward end of the extension shaft 19 and meshes with the bevel pinio n 23 upon the shaft 16. he pin on 22 is controlled by a eltitch constriietion 24. 90 Th e shaft 16 extends beyond the side of the frame 12 ,Lnd has tn end 25 ,tdapted to be engaged by a suittble crank wfench for starti ng the engine. Tn starting the en,-ine the clutch 15 is disconnected and the clutch 95 24 connected, and after the engine is started the clutches 15 and 24 may be manipiillted as desired. A brake drtim 26 is fixed iipon the sh,,tft 14, a brake band 27 is connected to ari abut- ioo ment 28 at one end ,tnd extends @iround the brak e drum 26, ,t ro 29 exten s throu the ab-Litment 28 and connects to the free en of the band 27, and a hand lover 30 operates the rod 29 so as to control the winding lo5 dru m' 13. Th e lever 31 controls.'the. clutch 24, the rod 32 controls the lover 31, and the hand leve r 33 controls the rod. The scraper or sbovel 34 has a b,,tck 35 fitting again-,,t the 110

[3]1,360)874 cable 86 the c,@ible will pull upwardly upon the forward end of the boom 72 thereby raisin,,), the kraper 34 c,,Lrrying the load of dirt, arcl as the s-Iraper is raised the tension of the o-uy 79 pulling upwardly on the back 35 lv4lll liold the sertper -Liprioht to carry the load, and as the scraper continues to go upwarc[13, the tension of the Yuy 't9 will inove the forward end of the bo;m 't2 to the left :Lo until Viie Oesired hei,ght is re,,tched, then an extra str,,Lln upon the cable 86 will upset the scrafer @uncl dump the loid as shown in dottecl nes n Fiu. 1. Releasing the cable 86 wi 'II allow the wei,-ht of the ser,,tper to swing 15 the boon-1 't2 backwardly toward its normal position. 1,Vhen the boom 't2 goes upivardly the tenSion of the Spring Doa will wincl'the guy '18 a Sa W' upon the drum 4 and the panvl ill hold 20 the drum 4a to hold the guy 78, so th,,tt wlieii the boom 't2 st,,trts doilviiwarclly the guy @S will be short and hold the scraper 34 some dist@,ince above the orotind. A nlit 3b is f ormed in the guy 78 in front of the 25 roller lb to limit the ivind;no- up moi,ement a of 'Lhe drui-n 4. When tCe boom '(2 has been lowered uiltil the guy ts is tiglit the boom 't2 will snvinz 1,,tter-all3T toward the post @l thus bringin@ the scraper 34 cli3-@e6tly 3 0 into line ancl then @he boom T--? will strike thc" Iliandle 9,1 ,tiid release the pawl 8a frojii the ptwl wheel ba and the weight of the boom i-vi-li -Liniviiid the guy 't 8 from the driiin 4,1 aiid allow the scraper 34 to settle str,,t.'Lglit 3 5 do-wn into place. Then the po-,ver will I)e ,tppl'ed to move the, Nieliicle forwctrdl to y plisli the scraper iiito the b,,tnl,: 40 to obtiiii ,,t iiev@T load. When it is clesired to cluiiip t'lic dirt to 40 the right instead of to the left the guy 't@9 will be connected to the guy ,tiielior 69 ,Lnd @-he I)oom 72 will be upo-.i the rightbtii-id side of the post 71. Referring to the modification shoivii ii 45 rA igS. 13, 14 and 15, the elevating frame 88 is built ilpon the extension frame 12. The rja"Lin fe,-,ture of the elevatin frame 88 con9 sists of the double track b,,trs S9 ,tnd 90 extencling upwardly from the forward end of the extension frame 12 and making a qliarter tlirn above the exteiision frame 12 and then going straight upwardly Ind outiv,irdly at i-iolit anoles to the axis of the machine. Pots'ts 91 t,.tnd 92 support the up55 per outor ends of the track bars 89 and 90 11 and Ire idapted to rest upon the ground ,i,nd to be moved ,tloug the surf,,tce of tlic, gro,,ind. At tho Lipper ends of the tr,,tek bars 89 tiiid 90 the track bars are separated 60 to produce the sidgle tr,,teks 93 and 94 and 95 ancl 96. The scraper 97 consists of a bottoln 98, a bc,ek 99 and sides 100 and 101 riuidly secutre,-l to.-ether. The U-shaped bail 102 is 65 pivot,,tl'ly coiinected at its lower encls to the sides 100 and 101 by pills 103 and 104. Stops 105 ,tre secured to the sides 100 and 101 to allow the b,,Lil 102 to swing upwardly to a vertica l position against the stops. The pins 103 ,tnd 104 are near the back ptrts Of 70 the sides and the stops 105 hold the scraper 'T'RO M t@ppljig forwardly. Wide wlieels -106 ind 10i ire inounted at the lower back cori-iers of tlje sides 100 and 101 to run Lipon the double track bars 89 and 90 ,Ind tO run 75 upon the siiagle tr,7tek bars 93 and 94. Narr6w wfieels 108 ond 109 are secured to the Lipper rear corners of the sides 100 ancl 101 in planes to run upon the clouble track bars 89 and 90 tiid to run upon the sing'le track 80 bars 95 and 96. Th e cable 110 leads from the ivindilig drum 13 upwardly around the guide p-ulley Ill upon the exteiision frlme 12 and upivtirdl y around the guide pulley 119- and 86 clown wa@clly arouild the guide post 113 aiid is att,,Lched to the center of the ball 102. The clutch lever 114 for opertting the ellitch constr uction 24 is mounted upon a I)i-vot piii 115 secure(-l to the frame and extencts 90 across the frame and is coiinected to a lever 116. The lever 116 is mounted upon'a pivot 11T and has ,Ln eye 118 in its free end, ,tiid the cable 110 s throtigh the eye 118. A nli'u 119 is fo= iii the cable 110 so that 95 wli(-,n the drum 13 is operated to ptill tiie scrtpe r 9@ to the tol) of the elevttilIL): frajiic, 88 the nut 119 ivill eiigtlge the eye 118 aii(t tlii-ow tlle el-uitell 24 otit and the Aveight of the sem, per 97 will plill the cable 110 the loo oluIier -Niay ,.iid reti-iril the sertl)er to 1'.ts iiormal position.
