At each end of the gir is a dei-rick frame K in which the Wheels K1 for the i arms K"i held byf'icables K* by which t. ey.

endless conveyers are mounted, and the material collected may be drunped at either end of each conveyer according to the direction in which the ,convey/ers are moved', and the material thus ldelivered. may be received in suitable wagons. or cars for transportation, or, illustrated in Figs. 1 and 2, ma be deposited on endless chains of carriers ''f' t The carriers K1" re shown as supporte o may be r: ised or lowered as required '01' swung Wit iin certain limits, to -deposit the material along each side f the excavation at suiiicient distance'to avoid interference with the cars LHJMQ/ing the 'rders Each ca r is supported' on a pair of trucks L and is maden-p of I-bearns suitably joined and extending longitudinally resti on bolsters and connected to the trucks y kingpins as usual.

slightly `in all directions. Beneath the girder-ends are springs L mounted on the bols-ters. and the latter are rounded laterally, as shown in Fig i?. to allow the truck to rock slightly under them.

(hi the outer far-es of the girders above the cars l, area strong ,lirackets or lugs A and behave their plane under faces are supports l.""fsm'urel.v .seated on the ends of the cars. 'l'hus equipped the girders may be held upright without regard tol inequalities and roughness of traf-k roadbed usually encountered in this class of work.

.Power for driving the various moving parts may be derived from `any source and applied in any convenient manner, electric motors may beemployed it' ,current'be available. rl`he driving mechanism is therefore onl \v partially ihdicaled inthe drawings; the turutaljlc is revolved byu vertical shaft l. and pinion P in mesh with a lixed annular rark Il on the carriage B; the vertical shaft lis'driven by beveled-gears l" 1"-l and l on the inainshaft and shaft P respeta, tively isturned in one direction or-lhe other. 1

Another Ivertical shaft R driven by beveled gears R2 R2 on the main shaft Cand shaft yR respectivelyY carries .a pinion "R1 in mesh `with an annular rack E* connected to the circle of pans E and drives thelatter.

T he swinging frame is moved and held by a cable S running on horizontal alleys S1 S1 atV the corners of the turntable rame C, attaehed tothe swinging frame and making a number of turns about a drum Sonl a vertical shaft, S3 driven by beveled` gears S4 S* respectively-on said shaft S3. and on a countershaft- S? carrying a pulleys on which runs a belt S7 from a pulley Ca on the main shaft.` A clutch S permits the pulley to engage the countershaft when the kswinging frame is to be moved.

A stationary engine I on the. tu-rntable- :may supply power for these purposes, and

engines Il Il at the-ends of the girders may supply` power for 'running the conveyers A2 andA carriers K2, and other purposes.

The cars L sup orting the entire apparatus are moved. a on y wheels L on the ax es, driven b worms L7 on a shaft L having universal ]oints L to provide fiexibility, and a. slide L10 in the midlen'gth' to permit telescoping for variatinns'in length as in traversing curves. The shafts L8 may be driven eachindependently the tracks' by wormf from the engine I1 on the adjacent end of the girders or ,in any other convenient manner.

Importance is attached to the construction of the excavating buckets Xl and fingers N2 in their relation tol each other; the

`fingers are'arranged in transverse rows on bars N3 between each pair of buckets and serve to loosen the earth or other material to be moved The ngers'all' project beyond the line of the working edges of. the buckets. and the outermost fingers of each row are f greater length than those between to insure a clear path for the sides of the succeeding bucket, thus tending to relieve the latter and the boom from torsional strains.

Atvthe extreme lower end; of the boom are rollers Fu serving to support the boom and 'facilitate its movements while inr Contact with. the surface. p. i

On the outer side of each girder near the top and bottom are runways or walks A? serving as decksor platforms for the attendants. and their supporting brackets and cross-bracingl greatly stiifen the girders.

Modifications may be made in the forms, proportions and various details of construction Ywithin wide limits Without de arting from the invention, and parts may used without the Whole.

Although the apparatus'is shown and delioequipped with a turntable and boom, three or more ma be employed, or one alone used if preferre The twoare preferable in that the tw'o setsof pans E may deliver each to one of the conveyer belts independently of the other. If more were installed they would deliver to the same belts. v

Such portions of the apparatus as are not fully shown may be understood tobe of any ordinary' or approved construction, and although theinvention is described as applied to canal or analogous engineering operations it will be understood that it may be applied to.ldred'ging,and to handling ores, coal or other` materials,. and iny other work to which it maybe adapted. .t I claimt-fv v j`1.-In an apparatus of thecharacter set forth, a pair of girders dis osed horizontally chain and and parallelv and provi ed, Vwith bottom stringers, acarriage sup orted by the bottom stringers Arml- 'of sai ,girders andmovable longitudinal y thereof in the space between them, a turn table in said carria e, a boom havingside bars, a conveyer o the ucket type mounted on said boom, the buckets of which are movable betweentheside bars ofsaid boom, cars movably supported on the turn table'on said carl tally Iand parallel to each ot er, a carriage.
