SPECIFICATION forming part of Letters Patent No. 278,399, dated May 29, 1883.

' Application filed February 13. i883 (No model.)

To all whom it may concern:

Be it known that I, D. IRVING CALHOUN, of Weedsport, in the county of Cayuga, inthe State of New York, have invented new and useful Improvements in Excavators and Loaders, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

The purpose of this invention is to expeditiously gather earth and other substances and elevate and dump the same ontoa suitable vehiclefor conveyingit away or onto an embankof deposit.

The invention consists, first, in the combination of a scraper or other suitable device for gathering earth or other substance, said device having thereon back of the center thereof draft-arms for the attachment of the draft chains or cable, a catch for holding said draftits said engagement.

bankment in process of construction.

The invention also consists in a novel construction and combination with a carriage mounted on an elevated track of an. arm connected with said carriageand adapted to engage the aforesaid tripping-lever, all as hereinafter more fully described, and specifically set forthin the claims.

In the annexed drawings, Figure] is a perspective viewof myinvention, illustrating its operation in gathering earth from the ground and the means for elevating-and depositing said earth either onto avehicle or onto an em- Fig. 2 is an enlarged isometric detail view of my invention' as applied to an earth-scraper; and Fig. 3 is a longitudinal section of the latter, taken. along the side of that portion of the handle which is attachedto the scraper.

Similar letters of reference indicate corresponding parts.

Arepresents a stout portable horse or trestle, provided at or near its top with a longitudinal track-rail, R, on which is mounted a carriage, G, of any suitable form and construction.

In front or in advance of the carriage G, I place on the track It a runner, T, in the form of a circumterentially-grooved rollertraversing said track, and having suspended from its axle a hanger, h, thefoot of which is connectconnection with the hanger. A spiral spring,

frame and hanger, and exerting an expansive force against said parts, serves to normally hold them asunder. A stop, s, is adjustably secured to the track R, and adapted to be set i at dilferent points in the length thereof, accord- ;ing to the location ofthe place where the scrap- To the foot of the hanger h is attached.an jarm, N, which is inclined toward the carriage ,O, and terminates with a vertically-elongated lface, i, for the purpose hereinafter explained. D denotes a dirt-scraper, preferably constructed of sheet iron or steel and of the ordinary form. The handles 1 of the scraper I so: cure along the top edge of the interior of the vof the handle by a web or flange, m, attached two flanges m, at opposite sides of the scraper, are hinged two draft-arms, a a, which are united by across-bar, a, and braced. laterally by braces a arms a is arranged back of the center of the scraper, so that a draft on the arms a will tilt the scraper forward.

To the inner side of the attached end of the scraper-handles is pivoted a hook or catch, 1), the free end of which projects through a slot in the web in, and. engages with its hooked end the top ot'the free end of the arms a, when the latter are relieved of the draft and laid 2 and 3 of the drawings. A spring, 1', arranged under the web m, back of the catch Z), and pressing against the interposed slide g, holds the catch in a position for interlocking with the draft-arms a.

c is a bail extended across the top of the scraper and hinged on the web m. The end of said bail is formed into a lover or crank, e,

from the side of the catch b.

To the forward end of the arms a are connected the draft-chains E, or a bail or rods, on which is hung a tackle-block, F. Around the block runs a cable or chain, a, .one end of which is firmly attached to the carriage 0, be-

fore described, the opposite end passing over ed with the frame of the carriage (J by a rod, 1', which is adapted to slide lengthwise in its '16, surrounding the rod 0'', between the carriage;

scraper-body and cover said attached portion down upon the scraper, as illustrated in Figs.

to the top edge of the scraper. On top of the.

Said hinge-connection of the.

which lies in front of a pin, d, which projects IOO 2 avaeeo a loose pulley, 0, pivoted to the forward end. of the frame of the carriage G, from whence said cable or chain is extended to the forward end of the upper portion of the trestle A, where it passes over a pulley, 1), connected to the upper part of the trestle, and thence passes around a pulley, 19'', connected to thelower part of the trestle. The horse or horses, being hitched to said end of the cable and traveling in line with the trestle, draws the scraper D along the ground toward the trestle, the operator in the meantime guiding the scraper by the handles 1, in the usual manner. The scraper thus becomes loaded in its approach to the trestle, and is then lifted and carried along in a suspended position by the carriage O, traveling on the track R, before described. The travel of said carriage is finally arrested by the collision of the advance runner T with the stop 8. By this collision the carriage G is caused to approach the runner T, and this approach causes the lower end of the arm N to throw back the hail of This movement of the bail 0 causes the lever end 0 thereof to strike the pin 61 of the catch 1), and thus throws the latter out of its engagement with the draft-artns a. This releases the front or open end of the scraper and allows it to tilt forward and discharge its contents, as illustrated by dotted linesin Fig. 1 of the drawings. The empty scrapercan then be moved back and lowered by backing the horse hitched to the cable a, and the operation of filling and lifting the scraper can be repeated in the manner before described.

ltcis obvious that the trestle A can be placed astride of a pit'or other place. to be filled or overa roadway to dump the load of the scraper into carts or wagonsfor carrying the substance to a distant locality; or the trestle'may be dispensed with and the track-rail R, with thecarr-iage O, secured to some otherst-ructure-such as a barn 0r storehouse-and a rake or other suitable implement used in lieu of the scraper,

said implement being rigged with draft-arms 5 a, held bya catch, 1), and tripped by a lever, c,

as hereinbefore described.

Having described myinvention, whatlclaim as new, and desire to secure by LettersPatent,

an eleva'ted'track provided with a stop, 8, and 5 5 a carriage having an arm, N, adapted to encounter the bailc, substantially as and for the purpose set forth.

2. In combination with the elevated rail R,

provided with the stop 8, the carriage O, mount 60 ed on the rail R, and the advance run ner T, provided with the hanger h, and connected with the carriage by the sliding rod 1", the spring-u, interposed between the hanger anti carriagefand the armN, extended from the hanger,substan- 6 tially as and for the purpose set forth."

- 3. The combination, with the scraper D, of the arms a, hinged thereon back of the center thereof, the pivoted hook I), provided with the I projecting pin d, the springf, back of the hook, 7c

and the bail 0, having the lever e in the front 'of the pin 61, all constructed, combined, and op erating substantiallyin the manner described:

and shown.

In testimony whereof I have hereunto signed 75 my name and affixed my seal, in the presence of two attesting witnesses, at Syracuse,in the county ofOnondaga, in the State of New-York, this 27th day of January, 1883.
