Application filed July 23, 1907. Serial No. 385,168.

To all whom it may concern:

-Be it known that I, WILLIAM MILES BROWN, a citizen of the United States, residing at Orookstomin the county of Folk and State of Minnesota, have invented new and useful Improvements in Excavating- Machines, of which the following is a specification.

This invention relates to ditching and excavating machines adapted to be used for digging or excavating ditches, drainage canals, and irrigation ditches and the like; and it has for its object to simplify and improve the construction and operation of' this class of devices; to provide a machine of simple construction which shall be operable in two directions so that it will not be necessary to turn the machine at the end of the excavation; to provide a machine in which the dirt that is being excavated maybe conveniently discharged at either side of the excavation and at a suitable distance therefrom; to provide an improved structure in which the excavating member shall be movable laterally of the frame of the ma chine,-so that an excavation of considerable width may be made without re-setti'ng or readjusting the machine; and to construct a machine of the character described which shall possess superior advantage in point of simplicity, durability and general efficiency With these and other ends in view which will readily appear as the nature of the inventionis better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention; it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the invention may be resorted to when desired.

In the drawings, Figure 1 is a top planview of a portion of an excavating machine constructed in accordance with the invention. Fig. 2 is a longitudinal vertical sectional view taken on the plane indicated by the line 22 in Fig. 1. Fig. 3 is a transverse sectional view taken on the plane indicated by the line 3-3 in Fig. 2. Fig. 4 is a'vertical transverse sectional view taken on the plane indicated by the line 44 in Fig. 2. Fig. 5 is a detail plan view of the laterally adjustable frame which serves to sup ort the scoop frame and related parts. Fig. 6 is a vertical sectional view taken on the plane indicated by the line 6-6 in Fig. 5. Fig. 7 is a diagrammatic view showing the machine in position for operation. 1

Corresponding parts in the several figures are denoted by like characters of reference.

The two ends of the improved machine are practically of identical construction; and in Figs. 1 and 2 of the drawings the central portion and one end of the machine, only, has been shown, for the purpose of showing the parts on a larger scale than would otherwise bepossible it being understood that the end of the machine which does not appear in these views is a duplication of the end which isshown.

The main frameA of the improved machine is preferably built of structural iron; it being composed of beams or bars of any suitable cross-section to insure the necessary qualities of lightness and strength; said bars or beams being assembled in any convenient manner to form a frame structure of the desired dimensions; the main frame beingsubstantially rectangular in shape, and supported at the ends thereof in trucks, one of which is shown atB; said truck including the wheels 1, axle 2 and bolster 3; the latter being mounted pivotally beneath the frame upon a king bolt 4 which is equipped with a pinion 5 meshing with a pinion 6 upon a steering rod 7 having a hand wheel 8 by means of which it may be manipulated to steer the machine.

- The main frame A supports at its center an auxiliary frame C including posts or uprights 9. This auxiliary frame supports a main shaft 10 which extends transversely across the main frame and which is of non-circular cross-section forthe greater portion of its length, as'will be clearly seen by reference to Fig. 2 where a shaft of s uare cross-section has been shown. Slidab y mounted upon the shaft 10 is a main driving pulley 11,

which latter is preferably grooved for the accommodation of a chain, cable or other flexible element which may be wound at least once around said pulley.

Suitably supported in brackets 12 that depend from the sides of the main frame, adj acent to the auxiliary frame 0, are transverse shafts one of which is shown at 13; slidably supported upon said shaft 13 is a frame D including the beams or side members 14, the outer ends of which are secured upon and connected by a plate carrying a suitably constructed scoop 16 having a sharp edge 17 adapted for engagement with the soil that is to be excavated.

18 is an elevator frame or trough, the upper end of which is slidably mounted upon a transverse shaft 19 of square or non-circular cross-section; the lower end of said frame or trough being loosely supported. upon the plate 15 adjacent to the scoop 16. The frame or trough 18 supports an endless carrier 20 of suitable construction; said carrier being mounted upon rollers 21 and 22, the former of which slidably engages the shaft 19, while the latter is mounted upon a shaft 23 near the lower end of the frame 18.

The main frame A includes transversely disposed channel bars 24, said channel bars being disposed in pairs above the lower end of the frame D; said channel bars serve to support a laterally slidable frame E wherein is ournaled a transverse shaft 25 having grooved. wheels or pulleys 26 upon which are wound chains or flexible elements 27, the free extremities of which are made fast to the frame D, near the free end of thelatter. The shaft 25 carries a worm gear 28 meshing with a worm 29 upon a shaft 30 which is suitably supported for rotation in the frame E and carries at its upper end a hand wheel 31 whereby it may be manipulated to effect rotation of the shaft 25, thereby winding or unwinding the flexible elements 27 and raising or lowering the free end of the frame D, as may be desired. The frame E also carries an upright shaft 32 having a hand wheel 33 and secured upon said shaft, and wound several times thereon are the inner ends of chains or flexible elements 34, the opposite ends of which are made fast to the sides of the main frame A thus it will be seen that by rotating the shaft 32, so as to wind one and unwind the other of the chains 84, the frame E may be moved transversely of the frame A, thus offecting lateral adjustment of the end of the frame D with which the said frame E is connected by means of the flexible elements 27 For the purpose of effecting lateral adjustment of the upper end of the frame I) there is provided an upright shaft 35, supported for rotation in suitable bearings upon th frame A and provided with a hand v. heel 3G. Suitably secured to the shaft 35 are the ends of a pair of chains or flexible elements 37, said flexible elements being guided over suitably supported pulleys 38 and connected with the opposite sides of the frame D, near the upper end of said frame. F or the purpose of effecting lateral adjustment of said frame D the shafts 32 and 35 are preferably rotated simultaneously and in unison, thus causing the said frame D to slide or move upon the supporting shaft 13, the elevator trough or frame 18 sliding in like manner upon the transverse shaft 1 9, until the desired. adjustment has been effected. liy this run struction a scoop of suitable width may be mounted in a supporting frame of a idth greatly exceeding that of .:aid scoop, and the latter may be adjusted to make an exravat ion of any desired Width \iithin the limits of the Width of the supporting frame in two or more operations, thus enabling a machine, capable of making an excavation of large dinnnsions to be o iierai'od successfully with romparatively light motive power. it is obvious t hat no limitation is made to the dimensions or proportions shown in the arrompauying dravv ings, but that the supporting frame may be made, relativel of much greater nidth, thus enabling a eorres 'iondingly vvide r e. ira vation to be made by the machine.

Supported in suitable bearings below and parallel to the main shaft 11) is a siaa't ihi which receives motion from said main shaft .10 through the medium of a chain it) eng=iging sprocket vi'heels upon. the aid shafts. i rlonnted upon the shaft 231) is a sprocket. wheel 41 from. vihieh motion transmitted by a link belt to a sprocket: wheel 1.; upon the shaft 19 21inch supports the upperond of the carrier tri'iugh it! and of ti o endless carrier mounted in said trough.

Suitably supported ansversil of the main frame in an endless carrier '11; said carrier being arranged l noatli the disrhzirgo ends of the carriers 21) in the troughs or frames 18 extending towards the tvso riids of the main frame A. The carrier-1i is mount ed upon rollers 115 upon longitudinal shafts 4.6; the means for driving the endless carrier 44 n ill be presently drsrribrd.

The sides of the frame A are provided r. it h lateral y extending lugs or hraeitets -17 supporting shafts -18 upon \rhirh thrrarriir fran es -19 are hingedly 11l 1l11i '(l 1 said fra ines are provided near their out or ends wit it shaft s 51 'nhirh serve, in conjum'tion with the shafts 48, to support endless rarrien-i :31 of suitable dimensions. .l f'ivoially sup iorted upon the shaft 49 adjacent to th lugs or iilffialhiS 41-7, are l:-ra -e rods 53 rabieh run-- verge outwardly to form V-shaprd frunns i the apices of uliich are connected with th sides of the carrier frames 111 by means of chains or flexible elements 5;). .dditional chains or .flexible elements 531 ('onnnrt th apices of the frames l! \Yit h shafts 5:; that are supported for rotation in the auxiliary frame C, said shafts 55 c mstituting drums upon which the flexible elements 5 .1 may be rxouud for the purpose of elevating the outer or free ends of the carrier frame Elfi. 'lhe drums or shafts 55 may be operated in any suitable manner; in the dranings, there have been shown. additional shafts 5d, supportrd par allel to the shafts 55 and having piuions 5T meshing with pinions 52% upon. the shaft 535. The shafts 56 are provided \-;it h hand v-Jhoels 59 whereby they may be rotated for the purpose of rotatin the shafts to wind or unwind the flexible elements 54, as may be desired, for the purpose of effecting the desired adjustment of the carrier frames 49. Suitable well known means of any kind may be used for the purpose of retaining the shafts 55 at various adjustments, or for the purpose of checking their rotation; but-such means are well known in this class of mechanism and have not been illustrated.

Countershafts 60 are supported for rotation in the auxiliary frame 0 above'and adjacent to the shafts 55, and said countershafts are provided with bevel pinions 61 meshing with bevel pinions 62 upon the main shaft 10, from which motion will thus be transmitted to the countershafts60. One of the latter carries a sprocket Wheel 63 which is connected by a link belt 64 with a sprocket wheel 65 upon one of the shafts 46 supporting the transversely disposed endless carrier 44, which will thus be driven.

Suitably secured upon the sides of themain frame A, adjacent to the endless carrier 44 are aprons 66 overhanging the carriers 51 supported by the frames 49 for the purpose of guiding material from the said carrier 44 onto either one of the carriers 51, as will be readily understood.

In operation the improved machine is intended to run in the ditch. or excavation that is to be made, the machine being obviously made of suitable dimensions, especially as to width, to make an excavation of a desired size.

The machine-may be propelled by power supplied by two stationary engines, one at either end of the work, the power being trans mitted by means of a chain or cable one end of which is attached to ashort tongue or draft member at the end of the excavator, the other end being attached to a drum or capstan device on the engine.

The elevators may be driven by a wire cable, V passing around the pulley 11 upon the shaft 10 of the machine, the ends of said cable being anchored or made fast in any suitable manner adjacent to the end of the path of the excavating machine, or the elevators may be driven by a gasolene, steam or other motor supportedupon the main frame of the machine, said motor being utilized for transmitting motion through any suitable intermediate mechanism of the shaft 10 carrying the pulley 11. It will be under stood, however, that no limitation is intended to be made to these or to any other particular methods of operating the machine to propel the same or to supply motive power to the live parts of the machine. Under some circumstances it may be desirable to construct a machine operable in one direction only but involving in its structure the principles herein shown and described a machine of such structure, which will be comconveyed over the scoop onto the endless,

carrier 2-0 whereby it is conveyed to the transversely disposed carrier 44, which latter discharges onto the carrier 51 at either side of the frame, thus causing the dirt to be discharged at the side of the ditch, and at any desired distance from the excavation. The

dirt may obviously be discharged into the boxes of dump wagons or other receptacles, if desired, or it may be dumped at the side of the ditch.

The machine may, as previously stated, be operated by a stationary engine, and when this is the case it will obviously make a trip or a length which is governed by the amount of available power, and by the length of flexible connections that are being utilized; when the end of the excavation or the end of the trip is reached, the movement is reversed; it being obvious that the scoop frame which is temporarily at the rear end of the machine will be raised to a position where it will not interfere with the progress of the machine.

The scoop carrying frame D may be readily adjusted by the means provided for the purpose, as hereinbefore described, and it is obvious that the lower or free end of the frame 18 supporting the carrier 20, which rests loosely upon the frame D will be adjusted with the latter.

The improved machine is simple in construction, and thoroughly efficient for the purposes for which it is provided.
