EARTH-BORING MACHINE.

Specification of Letters Patent.

Patented Sept. 9, 1919.

Application filed May 9, 1918. Serial No. 233,602.

To all whom it may concern:

Be it known that I, WILLIAM A. MnYERs,

cisco and State of California, have invented a certain new and useful Earth-BormgMachine, of which the following is a specificabodies a machine which can be detachably mounted on the chassis of an ordinary motor truck, and its operating mechanism coupled to the engine shaft of the auto motor, thereby enabling the drilling operation to be effected by means of power derived from the motor car engine.

Speaking more spec1fically, the invention,

from a structural standpoint, embodies sev-' eral novel features, among which may be mentioned the following. A fixed frame or platform which may be secured to the chassis of the motor car, and thus form the base or support of the boring machine; a movable platform or support, upon which the operating mechanism of'the boring machine is directly mounted, and which is movable relative to the stationary platform, whereby the boring tool may be placed in a w1de range of positions; improvements in a pivotally mounted tower in whlch the boring tool and its shaft are mounted, whereby the tool may be operated at any desired angle; improved means for adjusting the angle of inclination of the tower; lmproved means for raising and lowering the boring tool and its shaft; and mechanism for adjusting the countershaft with reference to the main driving shaft of the boring machine to compensate for thediiferent positions of the slidable platform with reference to the stationary platform.

Features of the invention, other than those adverted to, will appear from the hereinafter detailed description,read in con1unction with the accompanying drawmgs.

The drawings illustrate the preferred, practical embodiment of the invention, but this construction is to be understood as illustrative, only, and, therefore, not exclusive of the dilferent embodiments of which the 1nvent1on may partake.

Referring to the drawings, Figure 1 shows the machine, in front elevation,

mounted on the chassis or frame of an autotruck;

Fig. 2 is a side elevation of the same;

F g. 3 is a top plan View;

Fig. 4 is a fragmentary'plan of the gearbox and its associated parts;

F g. 5 is a section on line 5-5, Fig. l;

Flgs. 6 and 6 are detail views showing the manner of securing the machine to the chassis; and

Fig. 7 is a detail showing the slidable connection between the auger shaft and its driving gear.

Referring to the drawings, and particularly to Figs. 1, 2 and 3, A designates the outlines of a motor car, the wheels thereof being shown at B. A plurality of I-beams 8, positioned transversely with reference to the'channel beams 9, forming the side memhere of the chassis of the motor vehicle A, I

constitute a stationary frame or platform. The ends of I-beams 8 are secured to the channel beams 9 through the medium of bolts 10, clamps 11 and nuts 12, said bolts extending through the upper flanges of the channel irons 9 constituting the side frame of the chassis, as clearly appears, in detail, in Figs.- 6 and 6"".

Superimposed on the stationary frame described is a movable frame or platform embodying a plurality of I-beams 13. positioned above and extending in alinement with I-beams 8, and the further set of I-beams 13 extending at right angles to beams 13 and secured thereto by gusset pieces 14, see Fig.' 3, thereby forming a rectangular frame. Two of the I-beamsl? of the movable platform are provided with legs 15, in each of which are journaled rollers 15' and 15 the rollers 15 riding on the upper face of the flanges of I-beams 8, and the rollers 15 on the under face thereof (see Figs. 1, 2 and 6), whereby the movable frame may be reciprocated with reference to the stanism. Shaft 20 is driven from the engine shaft 22 or shaft from the reversible transmission ge'ar through the medium of gear 21 on shaft 20, gear 23 on the engine shaft and the sprocket chain 25 which meshes with said gears.

Fixed to the shaft 20 (see Fig. 3) is a miter gear 26 coiiperating with another miter gear 27 mounted on a counter-shaft 28 ,journaled in bearings 29 and 30 positioned on the movable and fixed platforms respectively; Secured to the forward end 'of-shaft 28 is a miter gear 31 meshing with a miter gear 32 fixed to shaft 33, whereby the latter is driven.

In order that shaft 28 may accommodate itself to different positions of the movable platform without disturbing the operative relation of gears 26 and 27, said shaft 28 is adjustably slidable through its bearing 30 and miter gear 27', thereby permitting the movable table to be shifted to different positions without changing the positions of gears 26 and 27. When the table has been placed, in its operative position for drilling, the gear 27 may be fixedly secured to shaft 28 in any suitable way. The bearing 29 is supported from any suitable crossing 29 which connects two adjacent parts 13, as shown in Fig. 3.

Secured to the inner end of shaft 33 is a pinion 34 which meshes with a gear 35, fixed to the auger or jack shaft 36, to the bttom of which shaft is detachably secured, in any suitable manner, (see Fig. 7) the anger or boring tool 37. The pinion 35 and gear 34 are housed within a gear-box 38, which forms a bearing for the auger shaft 36 (see Figs. 1 and 4).' Fixed to the upper end of shaft 36 isxa cross-head 39, slid'ably mounted in a suitable frame or tower, hereinafter to be described, for the purpose of raising and lowering the auger and its shaft.

Pinion 34 and gear 35 are fixedly mounted in the gear box 38, and this construction necessitates, of course, that the auger shaft 36 be slidably mounted relative to gear 35, in order that said shaft may be reciprocated therethrough. This slidable movement may be effected in any suitable manner, as by providing the shaft 36 with a key-way as 36', and the gear 35 with a feather 35 that fits therein, (see Fig.7) thereby coupling the shaft and gear for rotation, but permitting of a sliding or reciprocating movement of the shaft relative to the gear.

Secured to shaft 33 is a gear 40 Which meshes with a gear 41 fixed to the end of shaft 42, which shaft is supported in beartower in a manner hereinafter to be described. To the opposite end of shaft 42 is fixed a gear 45 which meshes with a gear 46 secured to shaft 47 mounted in learings 651819, on the movable platform'Fl'It will,

ings 43, 44 (see Fig. 1) mounted on thethus, be seen that power may be transmitted from shaft 33 through shaft 42 and associated gearing to shaft 47.

The tower, hereinbefore referred to, embodies any suitable form of supporting structure, such as angle irons 51, the upper ends of which are connected by a tie member 51, and the lower ends of which are connected by cross-pieces, pivotally mounted on shafts 33 and 47, thereby providing for a tiltable movement of the frame, for the purposes hereinafter specified. This tower may be reinforced by means of a cross-piece 52, from which extend inclined members 53, the lower ends of which are provided with forked members 53' which pivotally straddle shafts 33 and 47 laterally of bearings 19, thereby enabling the bracing members 51 to partake of the movements of the tower, whereby the tower and its reinforcing members may be inclined at such angle as to transport it effectively, but, more particularly, to enable the auger to be presented to the surface to be drilled, whether horizontal or inclined, at any desired angle.

The tower may be securely held in its vertical or inclined positions by means of pipes 54, pivoted at their lower ends, as at 55, to the movable platform. The inclination of the tower is effected by means of slidable sleeves 56 on pipes 54, said sleeves being connected by a tie member 57. Pipes 54 and sleeves 56 are provided with registering openings, thereby permitting the sleeves to be locked in any desired position 100 on the pipes by pins 58.

he mechanism for raising and lowering the. auger shaft embodies a gear 59 fixed to shaft 42 (see Figs. 2, 3, 5 and 6) and this cotiperates with a gear 60 mounted on a 105 shaft 61 journaled in housings 62, extending upwardly from the top of'the tower. The endless chain 63 coiiperates with gears 59, 60; and the cross-head 39, heretofore dcscribed, is provided with a tooth or lug 64 110 secured to the chain, whereby the cross-head parta-kes of the movement of the chain, thereby lifting or lowering the auger shaft and auger in synchronism therewith.

The movable platform, carrying the drill- 115 ing machine, is reciprocated on the fixed platform by the mechanism now to be described. Fixedly mounted on one of the 'I-beams 8 are gear wheels 65 on which travels the endless chain 66, movement being im- 120 parted to said chain through the medium of crank 67 which directly drives one of the gear-wheels. Depending from the adjacent beam 13 of the movable platform is a tooth or lug 68 which has a fixed connection with 125 chain 60, whereby said movable platform may be recipromtcd in either direction depending upon lhc direction of motion imparted to crank 67.

It is usually desirable, in order to give the 130 boring mechanism an extended range of operation, to provide for extending that portion of the movable frame carryin the bor-' ing tool somewhat beyond the side bar of the chassis. There are various Ways in which this might be accomplished as is obvious or a simple way is shown in Fig. 2, wherein the vI-beams 8, on which the rollers 15, 15 of the movable frame ride, are extended laterally.

the loosened earth. Any suitable means,

which it is not deemed necessary to illustrate, may be employed for readily throwing shaft 20 out of operative engagement with the engine shaft.

The machine is particularly speedy and efficient in operation and requires no special skill in its operation. Moreover, it is adaptable, or can be readily made adaptable, for use on any special or standard motor car.

It will be understood that slight changes may be made in the mechanism described, such as the substitution of equivalents, or a change in location of the boring mechanism with respect to the motor car engine, without departing from the spirit or substance of the invention, the scope of whichis commensurate with the appended claims.
