A ORNEYS.
Patented Sept. 29, 1931 l Y 'aixciufrruzrmf scoorA i AppuaumleaFem-1151111930. rserial 'nog 426,694.
My invention relates `to .excavating scoop. It relates more particularly toascoop. having two material-receivingz compart-4 ments andmeans` adjacent each compartment for penetratingandcutting the material to be excavated. 1
Most of the present day scoops comprise a body portion. provided `with teeth yattached to the lower forwardcdge thereofi- These teeth serve the function of breaking thematerial in advance of the scoop,thus facilitat ing the ready entry of thegbrokenmateria-l"v into the interior of thescoop. l
When operating in hardqpan, or similar substance, especially inl trench ,work where the trench is narrow-walled. .and` the dipper is precluded from lateral movement, the'teeth plow urrows in the hard pan, and with `AeachL succeeding stroke tend to reenter the alreadyformed furrow. It can be seenireadilyithat the dipper teeth will follow the path of, least resistance and will, under such circumstances, beY rendered useless :for digggging.,` i 1.
One object of my inventfl lies `in the provision of a scoop having meanswhereby the urrows plowed in the groundor hard pan, by the digging' teeth on ,thel forward end ofthe scoop will be removedc during each digging operation anda clean diggingsurface will be presented for eachsublsequentgdigging operation.
Another y provision of a scoop that may be ly with a minimum stroke. x
Still another object of my obj ect LVof myinvention lies .y @he 511851 rapid.-
k invention lies in the provision fof an excavator bucket tliatf is provided with a pluralityfof`v entries and compartments for thereception of excavated material. 4 f
A novel feature ofmy inventionllies inthe provision of a cutter plate disposed inrthe rear of the mouth ofsaid scoop and .ei'ective on the material. tobe excavated at,v a levell below the bottom ofthe bucket', to cut out the furrows ,formed bythe teeth adjacent the,
mouth of the vscoop and todirect the material forming suchffurrows into the interior of the scoop. `i f Another novel feature of my invention lies' in the provision of a scoop that is adapted to receive. excavated vmaterial through lthe 'mouth thereof and through an opening disposed in rear o such mouth'. The provision of this double entry will allow the scoop to be filled with rapidity, yet themateri'al there.,-v lnma-y-bed-ischarged freely through the forf ward open end of the dipper.
. kkStill another novel feature* of myv invenl.
tion lies in theffact that I provide, inreality',` two compartments separated by, a swinging door; each Acompart-ment 'having an entry'` ora mouth and-amaterial-penetrating means in cooperation therewith,to break up or cut, and tov facilitate theentry of excavated mafv terialthereinto and,. in addition, thejswinging door forms the rear wall`ofthe;forwardk compartment and precludes ,the` escape of excavated material into the rear compartment during the digging operation. lDuring the emptying operation, the door swings out of position allows the exit of all material inthe second comp artment through the forward'` l month of the scoop. a l
A `Otherzobjects .and a:dv'antageousy features f ofmy invention will besliown and described 4in the .accompanying drawings andthe writ ten ydescription 4*wherein similar characters of' reference Adesignatecorresponding' parts and Whenzfi j i. p
Figure 1 isa perspective view showingthe preferred embodiment of `my. inventionf:
Figure' -2 is a longitudinal e sectional view Showing: the 'scoop during the digging loperation..v- `f1, A. Figure 3 `is a longitudinal sectional view showing the f scoop during .the emptying y op; eration. w
betweenthe two compartments and plate, hinged door and door stops removed cated lower portion from which thescoop is hung. The scoop is not limited to a dipper stick mounting but it may be suspended. otherwise, as vfrolnthe cables, or chains 4, kFi'gfV ure 2, for drag linework. A hauling line 28- may be attached to the forward end ofthe dipper.
This scoop is, preferably-formed side', walls 5, bottom 6 and curved rear walt asf shown. The top and forward end are prefer ably Open. The lower forwarde'nd'ofthebot Fteeth Sfandf is..removi1lg this furrow in the tom 6 is providedwith teeth 8. yAnd the forward ends of the sides 5 are provided with;y side rake teeth '8a. 'These teeth may be of any type desired. f
The bottom 6 of this s coop isprovide'd, ad
" jacent its rear end, with a transverse opening' 9.v The sidesof the scoop adjacent this transverse opening are. cut away vertically. as at 10. A cutter plate 11.,.eomprisingthe' twoV vertical brackets 12 and van integrally formed inclined lip 13termin'ating in the cutting edge 14, is disposed adjacentthis opening 9. The cutter plate brackets 12 may be firmly riveted or bolted to the .sides'of the scoop.
In Figure ,2, it will'benoted ,that'thetbot tom of the scoop is maintainedat substantial.-
, ly the same plane throughout its-length Thel dipper teeth 8 depend somewhat below' the bottom of the bucket, that is, the lower` faces of the teeth, as at 15, are disposed in a lfnlver` planethan thebottom of the scoop.. The cut-V ter plate 11 is so disposed that the angling lip y13 thereof extends downwardly to such'an extent that the cutting edge 14 will be on line Yth the lower faces 15 of the teeth v8. If des1red,the plate 11 may extend belowthelevel of the faces 15 ofthe teeth 8.
' V.The interior of the bucket provided with a swinging door member 17, located approximately at the forward edge of the opening 9. The upper yend of this door has aho'llow sleeve 18 formed integrally therewith, Figure 4, and a rod as' at 19 (shown in dott'ed linelextends therethrough i ,and is journaled in suitable bearings 21 disposed inthe snpportig'blocks 22 that are mounted'on the interior'of'the bucket walls. 'i
This door forms the rearwall oftheffor` ward half ofthescoop. Itis adapted to' swing forwardly only and the stop members 24, which ycomprise narrow strips of metal, or similar material, are' disposed en the inner faces of the side walls 5adjacent the opening 9, as shown, to preclude the door fromfswjinging rearwardly to obstruct this opening 9. If
from entering desired, a strip may be Idisposed across the bottom of the scoop intermediate the two strips 24 to further aid in limiting movement of the door'past this point. The door is preferably hung as near to the forward edges of the opening 9 as possible, it being obvious that the further back the door is positioned, the greater will be the capacity for holding material in the forward end of the scoop.
In operation, the scoop may be attached to an excavating machine in any one of several well known methods, such 'as by a drag line or a stick, as illustrated. Figure 2 shows the teeth 8 entering the material to be excavated and the vletter-YA shows a furrow that f isbeing formed'underneath the bottom of the The cutter plate 11 is penetrating this material in line with the faces 15 of the manner shown. The excavated material is directed into 'the rearhalf of the scoop. The forward half is being filled, as shown, the dirt therein' packing against the door 17. It `will be seen readily that the excavated material in the forward 'compartment will be precluded the rear compartment.4 f
Whenfthe'- ucket is dumped, the mouth of the scoop falls forward, as shown in Figure 3, andthe excavated material in both compartments falls therethrough. The door y17,
since itis pivotally mounted, always tends to hang vertically, and swings outof the way of the material. Thus, the material in both compartments, although taken in at two separate entries, is exude'dthrcugh the mouth of the scoop.' When the material is dumped, the door Vassumes the positionl shown in Figure 3 and does not interfere with, or preclude the discharge'of material. Q,
If, for any reason, the material should pack in the 'forward compartment, the mass of material in 'the rear compartment, falling against the doorl 17 ,will assist in forcing the material 'tout' of the forward compartment. Itjyris obviousv that drop bottom scoops may be equipped with the cutter plate, it being only necessaryv to provide the proper opening vinthe bottom of-the scoop. :The'door 17 couldjb'e easily mounted Vin la'seoop of this'type and, if desired, itcould be lprovided with the proper means to prevent it fromswinging. i
kdoor lvshouid swing rearwardly. and the real-'dumping doorco'uldbe connected thereto Sothat they vcould bothbe moved simultaneonsly, or, if desired, a separate means for moving the' door could be Lutilized, e
Having thus described my invention, what I claim is: i
l. In an excavating scoop, a body portion, material-penetrating means adjacent the mouth of said body portion, a memberk mounted to swing within said scoop, an opening in the bottom of said body portion inrear of said swinging member and a cutter plate on one wall of said opening.
2. In an excavating scoop, a body portion, a hinged door within said body portion, an opening in the bottom of said body portion in rear of said door and a material-penetrating means extending below a wall of said opening.
