To all whom it may concern.'

Be it known that I, CHARLES E. BATHRICK, a citizen of the United States of'America, and resident of Chicago, Cookcounty,1l1i nois, have invented a certain new and useful 'Improvement in Excavating Machines, of `Which the following is a. specification.

My invention relates to machinery of the kind employed for general excavating purposes, such as grading, but more'particularly for building ditches, andpfor other similar purposes Arequiring a level road-overv-'hich the machine can advance in the direction of the excavation, For example, a drag line excavator is of this general character, and when used .for this purpose requires, very often, the leveling of the ground ahead or in advance of the machine. This, of course, must be done by a separate machine, under the conditions prevailing prior to my invention, and usually with some difficulty and at considerable expense.

My invention contemplates, therefore, a combination dipper and drag line excavator,- the dipper being disposed at the forward end of the machine to level or otherwise prepare the ground over which it must travel, and the drag-line bucket being arranged to operate at therear of t-he machine, whereby the one machine is suiicientiorjboth pur=V4 poses, and thevwork of preparing or leveling the ground and then forming a ditch therein is expedited and rendered more satisfactory in general. The nature and advantages of my invention will, however,hereinaftcr more fully appear.

In the accompanying drawings-Figure 1 is a side elevation of the front or dipper end of a machine embodying the principles of my invention. Fig. 2 is a side elevation of the middle portion of said machine. Fig. 3`

is a side elevation of the rear or drag-line end of the machine.

As thus illustrated, and referring to Fig. l, the front of the body A has a turn-table B thereon, which turn-table has a boom b' pivoted at b and provided at its middle with a pivoted arm b2 that carries a dipper b3 of any suitable character. The said dipper arm is operated or controlled by a rope` b* that is attached to the mouth of the dipper b3, and which is arranged over the sheave b5 on the end of the boom. From here the said rope then extends rearward along the boom to the sheave b on the turntable,and thendownward-'around the sheave '1)7, the vertical portion ofthe rope between the sheaves b and b ybeing coincidentwith" the axis of the turn-table. The boom is yraised and lowered 4by a rope bs that runs bs are operated by a drum or windi-ng mechanism D, which latter may be of any Well known character and controlled in any suit? able manner,'being driven by an engine l through the medium of a suitable connection.

The rear end of the body A has a turntable E upon which a boom eis pivoted at e;

said boom having its outer end provided with sheaves e2 and e3, and with a third sheave e4 for the ropeor line e5 by which the boom is raised and lowered.` This rope or line extends over the sheaves 6 and e7 on the mast es, which lat-ter has upper and lower sheaves e and el". The turn-table E has a sheave e, and directly below, onv the body A, there is a sheave 612. The drag-line bucket F may be of any suitable, known or approved construction, and is operated by a drag-line f that extends over and under the sheaves e and @12, the vertical portion of this line being coincident `with-.the axis yof the-turn-table F. The bucket hasa'hoist line f that extends upward over the sheaves e2 and c, and a dumping line f2 that extends upward and over the sheaves e3 and c, the hoist line being attached to the rear edge of the mouth of 'the bucket, and the dumping line being attached to the bottom of the bucket. The lines or ropes f and f2 lead to the drum or winding mechanism G, while the lilies or ropes f and lead to the drum or winding mechanism H, which are driven by the engine al and controlled by any suitable means. The line f runs between the guide sheaves f3 on the boom.

The masts C and es have their upper ends connected by a rod I, and said masts are also connected vby the crossed braces J, whereby a strong superstructure or frame is insured. l

The body A is supported on wheels K or other suitable devices for enabling the machine to move forward in the direction desired for the ditch.

The mode of operation, in making a ditch a; with the'drag-line bucket F, is as follows: The dipper b3 is employed for smoothing olf lso' or leveling the ground in-front of the Vmachine, any suitable expedient being '..employed for causing the dipper to dump its load.A This is done Aas the machine'moves forward from time to time, and at the same 'same machine. This means, of course, that fewer attendants are necessary than heretofore, and that a saving is effected in the cost of constructing the ditch. s

What 'I claim as my invention is:

1. In an excavator, a body, a vturn-table with a drag-line bucket equipment at one end of said body, and a turn-table with a dipper equipment at the other end of said body. i y

2. In an excavator', a body, a ditching apparatus at the rear end of said body, and an excavating apparatus on theforward end of said body.

3. In an excavator, a body, aturn-table with a drag-line bucket equipment at one end of said body,'a turn-table with a dipper equipment at the other end of said body, and a power plant and winding drum mechanism for the entire excavator, carried von the middle portion of said body.

4., In an excavator, a body, a ditching apparatus at the rear end of said body, an excavating apparatus on the forwardv end'of said body, and apower plant and' winding drum mechanism for lthe entire excavator,

carried on the middle portion-of said body.

5. In an excavator, al body, a turn-table with a drag-line bucket equipment at" one endy of said body, a turn-table with a dipper equipment at the other end of said body, a mast for each en d of the excavator, vand brace members connecting said masts together, wheels for said body, an engine near the forward end of the body, a winding drum mechanism vbetween theengine and the rear end of the body, therebei-ng comprised in `the foregoing a boom overhanging each end of said body.

6. In an excavator, a body, a ditching apparatus at the rear end of said body, an excavating apparatus on the forward end O f said body, a mast for each end of the excavator, and brace members connecting said masts together, wheels for said body, an engine near the forward end.. of the body, a winding drum lmechanism ,between the engine and the rear end of the body, there being comprised in the foregoing a boom'overhanging each end of said body.

Signed by me at Chicago, Illinois, this fifth day of January, 1911.

CHARLES E. BATHRICK.
