A further object of this invention is to provide improved ymeans for dumping a skip.

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in the claims and illustrated by the accompanying drawing, in which# l Figure 1 is a plan offthe'complete machine. Figure 2 isan end elevation of the same. Figure 3 is *a-crov tially centrally of the machine. Figure 4 of the machine.

In the construction of 'the machine as shown a suitable frame lis built up' of skeleton form of beams bars, standards and braces and comprises generally a base or draft frame and a superstructure carriedthereby, which frame is supported on

trucks

10, 11 adapted for travel `on track rails 12.

The track lrails 12 are suitably supported be moved conjunctivelyl and are adapted to laterally relative toa pile or'rick of substance to be gathered, elevated, loaded and.

transported by the machine. The ygeneral frame'of the `superstructure is formedvvith an opening in its side farthest'froin the substance to be moved, Which opening'extends across the centerof the frame. A skip or hopper 13'is` mounted in the central portion ofthe superstructure frame, rests at one side on a side beam 14 of the -baseframe and projects slightly.; through the side space above mentioned. The skip v13 i's formed with an outerl sidewall at the side thereof I farthest from the substance to be moved7 end Walls at right angles thereto and a bottom, butis open on the sidethereoflnearest thisinvention is to y ss-section substan- '.y' e 'Application led October 19, 1925.

saidshaft also extending longitudinally of thevskip and frame. l

the llower portion ofthe A stub axle16 is fixedv to and extends laterally from the center of side Wallof ther skip 13 and a dumping Wheel- 1.7 iscarriedy thereby and'is adapted to travel on an in:

clined track` elevated relativeto the .rails 12 and oscillate the skip for dumpingk the contents thereof between the vrails 12, atm times. Thelinnery ends of the end Wallsl ofV the -skip 13 are 4inclined land a plate 18 is mounted on the superstructure frame and.

The hub 21 is substantially at right yangles to the-plane of the plate 18 and is journaled on an. axle 26 extendingthrough the plate and through'the block, 20. thussuspendingl the Wheel in aninclined plane substantially a `"shelf adapted to.. receive `*substance from the uppermost pockets of the'wheel and "deliver it laterally into the skip 13.` lAshield 28 Yis fixed to the frame and normally over- `lies the lower portion of the wheel exceptv the open fronts of the pockets therein. Brace

arms

29, 30 are fixed to -theforward inner corners vofthe base'frame'and drags 31,. 32 are pivotally suspended from said arms and have their lowerfmargins sub-- stantially 4coincident with the groundsurface. The drags 31,732 are kadapted' to swing outwardly freely, but noty inwardly, so that,in the travel ofthe machine in eitherdirection, one drag willengage and move substance on the groundsurface away fromthe inner rail'12 while the-followingydrag will pass ,freely over such substance as may lie in its path. A shaft 33 is Amount-A ed for oscillation inl bearings34, 34on the mainframeand extendsbetwe'en the drags 31, 32 ina horizontal position)` A yoke 35 is pivoted at one end kto onewend portion of the shaft 33 andr extends,A as a square arch, laterally therefrom`-away frointhe basey frame. Agathering blade or scraper Y 36 is arranged normally horizontally atan oblique angle to the base frame and is fixed, near its forward runner end, to'the outer y arm of the yoke and saidblade isixed i at its rear end to a collar 37 o n the central The blade orl portion vof the shaft 33. *y scraper 36 extends rearwardly, across the transverse, center of thelmachine and into' 1 proximity with the lower open face lof the Wheel. 1A shaft y38'is mounted' parallel with,` in a lower lplane thanV 50 the yoke 35. The shaft 38 is journaled at;v

at 'i the yrear. of and oneend'in a bearing collar 39 `fixed to the shaftv33fand .is journaled at` its outer end ina bearing 40 carried by the scraper or bladep36., A disc wheel or'rolling coulter V41lis Afixed to the shaft38 between the scraperorr'blade 36 and theshaft 3 3 and is adaptedto engage the substance to be moved vand cut, agitate. and loosen Vsaid substance for action thereon .of the scraper. A Vhand lever .42,'is pivoted at one end fon afulcrum 43 mounted Ain the ,superstructure frame and `normally extendspartiallyacross said frame in` aL horizontal position. The'y hand lever 42-is provided with a detent 44 Yadapted for engagement with a rack-bar 45 carried by the superstructure frame and hold said lever 1n any position in which it may beplaced manually. An extension bar 46 is pivoted at one end on the fulcrum 43 and extends in alinement with thehand lever 42. A

"strut47 isipivotedatone end on the fulcrum 43 and rises therefrom. Braces 4S, 49

Vare connected at their inner ends by a bolt 59th the upper end of the strut 47 and extendlaterally and downwardly therefrom and are connected at their outer ends to the extension bar 46 andv hand lever 42 respectively. Thus is the hand lever 42 t-russed. f

A chain 52 is arranged obliquely and connects the outer end of the extensionv bar 46 -to the forward end portion of the scraper orblade 36. Thus the scraper or.blade 36 may be raised and lowered, together with the ycoulter 41, bymeans ofthe hand lever 42. Such movement of the scraper or blade 36 results in oscillation of the shaft 33 which articulates about its axis in the bear ings 34.- Eyes or clevises y53 are fixed to the central portions of the end bars of the base frame and draft means, such asa cable or coupling of a pullmgmachl'ne, may be attached thereto selectively. The machine may be drawnfalong the rails 12 by cable, animal power or in any suitable way, rearwardly to position vthe machine relative to the substance to bemoved and yforwardly to engage andv move saidsubstance. After aV rearward movement of the machine ,toy

initial position,'the track rails 12 `are ad-Vv justed laterally vrelative to the `pile or rick' ofA substance. Then the scraper or blade 36 is lowered, by the hand' lever 42, so that its ruimer margin is on the ground or floor surface and vthejcoulter 41 is engagedv with the ground.v Then the ,machine is moved forwardly andthe Yscraper or bladeV 361engagesfanddathers aquantity of the substance toward and into the outer openings of the 'pockets of the elevating. wheel,` said wheel revolving' by engagement of its spokes with the ground or floor surface and raising the substancein its'pockets vand ,deliveringv the same over the apronv 27 into the ski'pf13f The machin'e'is advanced until the skip is loadedv and, during such. advance. the drag 32 pushes loose substance outwardly toward the path of advance of the scraper or blade 36, During the reverse movement of the machine the Vdrag 31 pushes loose material into position tobe engaged by the drag32 in its next advance.' After the skip is loaded, the scraper or blade 36 and coulter 41 are raised by the lever 42 and the maf chine is further advanced up an'inoline or over va-pit not shown to a position or vplace where it is desired to deliver the substance such as over a wagon, car or fill, and, then, the'slrip 13 is dumped, preferably'byl the elevation of the zdumping wheel 17 by an inclined or arched dumping. track, not

shown. T he contents of the skip are dumped between t-he track rails l2. Thereafter, the skip is allowed to assume a normal horizontal position by gravity when the dumping wheel 17 is withdrawn from engagement with the dumping track. The machine is primarily designed for handling coaland also may be utilized in handling sand, grain, loose earth and other granular substances.
