GEORGE HENRY DUNLOROF AUBURN, VICTORIA, A'U'STRALI ExcAvarINe-Maonrnnf Specification of Letters Patent.
Patented July 2d, 19t?.
Application filed November 17, 1911. Serial No. 660,786.
To all 'ui/wm 'it may concern Bo it known that l, GEonoE HENRY DUN- Lor, a subject of the King of Great Britain and Ireland, residing at No. Q0 Robinsons road, Auburn, in the British State of Victoria, Commonwealth of Australia, have in- Vented new and useful Improvements in Excavating-Machines, of which the following is a specification.
This invention relates to excavating machinery of that type in which an excavating scoop or bucket is guided in its course across a cutting, such as a channel by runways, in which the scoop is suitably mounted on wheels, and which runways are shaped to conform to the profile or transverse cross section of the cutting to be excavated.
The objects and nature of the invention will be readily understood by those skilled in the art in the light of the following explanation of the accompanying drawings illustrating what I now believe to be the preferred embodiment from among other constructions and arrangements within the spirit and scope of the invention.
The invention consists in certain novel features of construction and in combinations and arrangements as more fully and particularly set forth and specilied hereinafter.
In the drawings Figure l, is a side elevation.
Fig. 2, is a part plan and Fig. 3, a cross sectional elevation taken from line a. a Fig. l, of a machine adapted to be used with a double acting scoop, the runway frame being raised and lowered by means of gearing mounted on one side frame and gearing for propelling the machine, while,
Fior. 4, is a side elevation showing a single acting scoop and runway frames pivotally mounted at one side of the cutting and adapted to be raised and lowered on pivotally mounted struts on the other side.
5, is a part elevation showing the runways supported on racks or screws supported on wheels on rails or on the ground, the axles of the wheels and the tops of the racks or screws on each side of the cutting being connected together.
Figs. 6, 6, 6b are side views of the scoop and part of the runways when the scoop is pivotally mounted on two wheels and operated by three ropes.
ln Figs. l to 5, on the axles A there are wheels B resting on the ground or on suitable rails; these axles A have bearings l on side beams F with vertical channel irons .l having bracing as K, K1, K2, said channel irons J being connected across at the top by channel irons L, L1. Each set of framing on wheels constitutes a side frame, one' at each side of the excavation.
The runway frames consist of a pair of braced girders as G, having their lower booms of channel irons as W, suitably shaped to conform to the profile of the cutting, with the flanges turned inward and forming runways for the wheels s, on which the scoop S is mounted. Upon the runway frames there are pairs of angle irons M flanges outward fitting closely but easily one at each side of each channel iron J ofthe side frames forming a sliding connection guiding the runways on the side frames, while on the axle A, or suitable framework, is a guide C which is free to move vertically in a channel iron c on the frame; or if desired two angle irons o1, may be used as shown in F ig. il. At each end of the runway frames the runways are enlarged into box-like chambers N, which constitute the reversing places in which the scoop is reversed. The framework comprising two running frames suitably braced together and carrying the scoop mounted in the runways is suspended from the side frames by two pairs of screws l?, one pair at each side frame, connected to the runway frames by pins as 771 through parts of the cross bracing 772, and passing through geared nuts T set between the pairs of channel irons L, L1.
The scoop S is mounted on axles S1 at each end having wheels s which travel between the flanges of the runway channel irons W. It is formed of a U shaped plate s1 forming those parts which are alternately the bottom or top of the scoop (according to which way it is moving) and the curved back, side plates s2 with bearings s3, attached at the front of the scoop and at the back of the scoop s4, for the axles. From the back of the scoop hauling ropes extend each around a guide pulley V placed one at each end of the runway over the reversingv places and thence to one of the winding drums a2, placed on the machine as shown. There is a guide pulley V1 placed at the center of the machine just clear above the space traversed by the scoop, under which the ropes pass so to render the pull on the scoop more effective when the scoop is on that half guides h2 and having a forked bearing 71,3 at theirI lower ends to carry the wheels B.
The process of removing a scoop full of earth with the single acting scoop with two ropes is precisely as described for the double acting scoop, but the scoop is so formed as shown that on the passage when empty it does not project much if at all below the runways and therefore clears the ground on the passage when not required to cut.
Ihe single acting scoop with three ropes is hauled by the main hauling rope Z tilted forward by the tipping rope Z1 and hauled back by the back-hauling rope Z2, the ropes Z1 and Zzbeing attached at the back of the scoop. The scoop passes across the cutting each way in the same position as the single acting two rope scoop, that is bottom down when filling, bottom up when returning empty.
rIhe single acting machine pivoted at one side of the cutting and raised and' lowered only at the other side of it is operated in the manner already described, but it is adj usted vertically for successive cuts by lowering it on the longer struts H1 and for different depths of channel by the struts I-I.
It will be evident that other well known means may be adopted for raising and lowering the runways and for propelling the machine, and that it may move on slides or on wheels on the ground, or on rails, or be mounted on a floating pontoon.
I'Iaving now described my invention, what I claim as new and desire to secure by Letters Patent is:
l. In an excavating machine of the class described, a scoop mounted on wheels, runways in which said scoop is reciprocated, and reversing places forming enlargements of the ends of said runways in which said scoop is reversed.
2. In combination, in excavating apparatus, runways, supporting means therefor, said runways having end enlargements forming reversing places, a reversible scoop movable back and forth longitudinally of said runways and provided with supporting wheels confined to travel in said runways and to said end enlargements therefor, and operating cables for propelling and reversing the same, substantiallyT as described.
3. In an excavating machine in combination, with runways and means for supporting the same, reversing places connected to the ends of said runways, a scoop mounted on wheels adapted to travel in said runways, means for reciprocating said scoop in said runways, means for overturning said scoop and wheels in said reversing places so as to reverse said scoop and wheels for making successive passages to and fro along said runways.
