To all whom it may concern..-

Be it known that I, THOMAS DILL, of Bay City, Michigan, have invented new and useful Improvements in Excavating- Machines, of

v I 5 which the following'is a specification.

My invention relates to excavatingmachines; and itconsists,flrst,in the combination of the dipper, hinged upon the end of a sliding stock or handle, with a bell-crank lever, a

connecting-rod between the bell-crank and the hinged dipper, and a slotted way or hearing adapted to cause the vibration of the bellcrank as the dipper-handle is reciprocated by the stroke of the piston, whereby the dipper will be tilted so as to present its cutting-edge to the earth, or thedipper be righted into p0-.

sition'for dumping, according to the direction of the stroke ofthe piston; second, in the combination of the hinged dipper and sliding upon the dipper-handle, a connecting-rod be; tween the'bell-crank and the dipper, a piston with'its rod attached to the dipper-handle for moving the same, and a casing formed upon the steam-cylinder and provided with a slotted way for vibrating the bell-crank lever, whereby the dipper-handle will be reciprocated by the stroke of the piston and the bell-crank leversimnitaneouslyszibrated to tilt the dip- 30 per; third, in the combinFtion-of the sliding dipper-handle, bell-crank lever, and casing upon the steam cylinder, the said casingbein g adapted to guide and support the sliding dipper-handle, and being also provided with a central longitudinal partition having a slot running in a horizontal plane aportion of its length, and then terminating in an inclined slot fourth, in the combination of the mast with a shoe surrounding it at its base and having a partial bearing upon the mast, also an independent semi-cylindrical collar applied against the mast as a continuation of the bearing of the shoe, a screw-bolt being arranged to tighten up the parts, and the crane being rigidly secured to the shoe and hinged to the mast, whereby by loosening the screw the crane may be tilted; fifth, the combination of the crane, hinged to the mast and rigidly secured to an independent shoe, with dipper-handle with a bell-crank lever mounted the shoe against the mast; sixth, in the com bination of the mast and the crane with a shoe having the peculiar conformation hereinafter specified; seventh, in the combination of a swinging crane with a steam-cylinder and piston swinging vertically upon ,trunnions journaled in the crane, the piston being connected with the sliding dipper-handle, so that the dipperhandle-may be reciprocated, by means of the steam cylinder and piston, and the-dipper may be raised without littin'gthe weight of the'cylinder and piston.

In the drawings, Figure 1 is a perspective view 'of my improved excavating-machine. Fig.2 is a side elevation of the same, showing the dipper in position for cutting into the earth. Fig. 3 is a side elevation of a portion of my machine, showing the bucket hauled up by the tackle'chain and in a vertical position, with its door open for dumping. Fig. 4 is a top or plan view of the machine. Fig. 5 is a. section on the line as 0;, Fig. 4. Fig. 6 is a sec tion taken on the line 3 y, Fig. 5. Fig. 7 is a vertical central section, mainly of the mast and the shoe at its base. Fig. 8 is a detached view of the shoe and its adjuncts.

I willhere premise that I propose emplo in g, in connection with my improved machine, an engine as the source of power, together with appropriate mechanism for swinging the crane: As I claim, however, no novelty in eitherthe engine or its attachments, I have deemed itunnecessary to herein illustrate the I), while the lower inclined timbers of the crane are securedat the base of the mast to a shoe, the functions of which will he presently described. The hollow mast B is so stepped that the craneA will swing freely laterally, as in ordinary dredges. Thecra-neis properly strengthened by crossbars a a and diagonal timbers or rods a, and it is provided at its jib-head with the requisite double pulleys c for the tackle-chains D. The hauling-chain, which is woundup'on a drum, (not herein shown,) enters I50 proper means for tightening the bearing of the hollow mast under a pulley, E, and passes :00

up and. over pulley, e, noon the crane near the mast-head, and then as to the double pulleys O at the'jib-hearl and. ronml the blocks, to which the dipper is suspended by a hinged yoke, F. r

In carrying out that part of my invention which relates to means for actuating the clippeohanclle and clipper I provide a steam-cylinder, G, with the usual auxiliaries for operm ating its piston G, and support the said cylinder upon the crane by means of suitable trunnions, so that; it shall be free to turn upon its hearings, The pistonqod g is'conuected at g with the (lioper-hamlle H, so that the 1 5 latter will move simultaneouslywith the strokes of the piston, The dipper-handle H reciprocates in a casing, I, which is either cast with or see real upon the steam-cylimier. This easing, which is formed with ledges i overlap- 2o ping the upper edges of the hanolle, serves both as agnide and a support for the some.

It will be seen by referring to Fig. 4 that the handle H is (liviilecl'along' izhas portion which works within the casing I, so that the 23 two sides of such. clivirled part will slide under the ledges i of the casing, as shown in Fig, 5. The dipper K is journaled at the hii'urcateil front end of the handle H, and in order to till; the dipper to the proper angle for presenting its cutting-edge to the earth and to right it into position for dumping, I employ a hell-cranklever, L, which, when vibrated about its axis, will tilt; the dipper through the medium of a connecting-rod, M.

H, and is vibrated simultaneouslj? was the reciprocations of the handle. As one'practical way in which this bell crank-lever may he actuated, I form its lower arm of two prongs,

, 4o whichstraddleacentrallongitudinal partition,

' "n, in the casing Land from the said prongs pass a pin through a slot, P, in the partitiois. This slot runs horizontally a portion of the v length of the partition, and then inclines Gown- 45' wardly as the end nearest the dipper, as shown ahP, Fig. 6. When the handle Hjs retracted by the action of the steam against the piston the movement of the lower arm of the helicrank lever in the slot will cause a vibration of the bell-crank lever, which, through the .medium'of the connecting-rod, will tip the diption enables me to force the dipper-into the earth to he excavated, anclyeg d'oes not add (the weight of; the cylinder and iston 11o fsh $51, A to he'raised by'the iaeklec ain.

, it is obvious thflaothe piston may he ochre This hell-crank lever is 5 pivoted in suitable bearings upon the handle atecl by water or compressed air without departing from my invention.

The flipper is provided with a hinged bottom, which may he opened. and ciosed by the devices in ordinary use for that purpose.

The shoe or collar Q, to which the lower end oi the crane A is secured, partially embraces arid hears upon the lower end of the mast, and is sloiierl longitudinally forward of the center of the mast, as shown in 1, so as to permil; the shoe to slide back of the mast when the crane is tilted, as hereinafter described; The remaining portion of that section of the mast which is not embraced by the said shoe or collar Q is embraced by a semieyiiodrieal means of a screw, the collar-Q.

By iooseoing the screw the crane may he tilted to a considerable extent, since its angle of inclination will only be limited by the check given. to the oollarpli; hy the wall of the shoe at thai side through Wlllflil the screw enters,

S, which has its hearing in cavatingmachine, as ehis has been done be- -fore; but
