This invention relates to combined earth 7 boring and derrick apparatus, and more particularly to arrangements of this character which are of the portable power driven type and adapted for boring holes and installing poles therein.

One of the objects of this invention is to provide a combined earth auger and derrick apparatus adapted to be mounted on a motor truck and so positioned that the operating mechanism therefor may be coupled to the engine shaft or power take-01f of the truck, thereby enabling the boring operation of the auger or the adjustment of the derrick to various heights to be effected by means of the power derived from the engine.

Another object of. the invention is to provide improved leveling mechanism for the boring mechanism whereby in case the truck is standing on sloping or uneven ground, the auger and connected driving mechanism may be adjusted by power to assume a plumb position; or where required, may be adjusted to bore in an inclined position.

A further object consists in the provision of braking mechanism for insuring positive locking action for the apparatus when in normal position.

These and further objects will be apparent from the following detailed description,

when considered in connection with the accompanying drawings in which one embodiment of the improved invention is illustrated.

In the drawings, inwhich likecharacters of reference designate like parts throughout: Figure 1 is an elevation partly in section,

The-apparatus shown on the accompanying drawings including the boring and derrick apparatus,

in detail, is adapted to be suitably'mounted upon a truck and operated by the truck engine through changeable speed transmission (not shown). The boring. apparatus functions to dig holes in whi h poles or the like are to be positioned and'the derrick apparatus functions to place poles in'these holes. This latter operation is performed by means of a line wound upon a wi ch drum carried by the truck, which passes over-a sheave carriedby the derrick and is secured at one end to a pole or the like.

113 and 114.

A drive shaft 69 (Fig. 1) is journaled in the upper part of casing 13 and has a pinion 70 on its lower end which meshes with bevel gear 36. An idler gear 71 is also carried by the shaft 69, and is provided with jaws for engagement with jaw clutch 72, which is splined to'shaft 69 and controlled by a handle 72 (see Figs. 3 and 10). This handle is mounted on a casting carried by casing 13. The drive shaft 69 also carries an idler sprocket 73 provided with jaws for engagement wzth jaw clutch 72. Bevel gear 71 is: in mesh with pinion 74, and this pinion has I an extended shaft 'to which. a sprocket 75 is attached. The sprocket 75, by means of chain 76, drives shaft 78. A double sprocket 109 lies between the

sprockets

75 and 77, and has a shaft 110 journaled in a double eccentric mounting 111, which is secured The'mounting of the shaft 110 in this manner permits the clamping of the shaft after adjusting each eccentric, in order to tighten the chains 76 and 7 6. Shaft 78 is journaled in a housing 79, and carries a worm which is in mesh with worm-wheel14. The housing 79 is bolted to casing 13 in a horizontal position and in such manner that when the worm 80 is driven it will turn the casing 13 and the attached casing 5 with its contained rack shaft and auger, to either side of is standing on e1 chain 73', shown in drives a sprocket 82,

,shaft 110 in Fig. 3.

-It-' will be thus seen that worm 80 will tilt the sprocket 77 which is keyed to in a clamping bracket 112. 3

provided with a lower the vertical axis of casing 39 according to the direction of rotation of the worm 80 on worm-wheel 14. The tilting of the casing 5 in this manner permits the auger to be 'adjusted angularly to the right or left as required. Worm housing 81 is bolted to casing 13 in a vertical position (Fig. 1), and when its worm 82 is driven, the worm-wheel 14 will raise or lower on its worm, thus tilting casing 5 with its contained auger forwardly or rearwardly with respect to the horizontal axis of casing 13. This permits the auger to bore in a plumb position when the truck her a horizontal or an inclined plane. Shift handle 7 2 is adapted to be moved to engage jaw clutch 72, with jaws of gear 71 and through mating gear, sprockets and chains to drive Worm 80 or to be moved to engage jaws of sprocket 73 on shaft 69. Sprocket 73,-by means of a dotted lines in Fig. 3, which is on the same shaft as the drive worm 82. A double' sprocket 109 lies between the sprockets 73 and 82', and has a shaft 110' journaled in a double eccentric mounting similar to that shown in connection with the gear 109 and This arrangement permits of adjustment to tighten the chains 7 3 and 82" through which sprockets 73 and 82' are interconnected. When the clutch 72 is. engaged to drive the sprocket 73, the chain of gearing above described operates the worm 82 (Fig. 1) to drive the worm-wheel 14; A neutral position is provided for handle 7 2. the operation of auger to bore in an angular direction to the right or left, and the operation of worm 82 will tilt the auger to bore in an an ular direction to the front or rear as seen rom Fig. 1. A derrick to be presently described, which is carried by the casing 5 partakes of the angular adjustments 7 ofthe auger shaft. A plumb bob 118 is attached to casing 5 (Fig. 3) to indicate the) plumb position of the auger. The rack shaft 7 has a cap 104 at its top (Fig. 7) which is provided with spaced projections. These projections successively register with associated arm to successively strike a gong a pivoted spring'and cause its 105 to signal that the rack shaft is near is v lowermost position. K j

The derrick shown in Figs. 7, 8 and 9 is tubular "portion 83 and an upper tubular portion 84 which telescopes therein. A stop 83' is attached to the tubular portion 83 and serves to limit the upward travel of the tube 84. The outer tube 83 is provided with a base 85, which may be bolted to the casing 5, shown in Fig. 1. A collar 86 is threaded on the end of the carrier 6, and is provided with peripheral ear teeth 87. These teeth mesh withlpinion 8, which idles on shaft 89 and this s aft\is journaled in the casing 85. Thef'shaft- 89' carries a 1 V be followed byjreferen'ce to-Fig. ;10,.-:pQeer3 A worm 95 which is driven through the engagement of the j aw clutch 96, which is operated by handle 97. A rack 98 carriedby the'inner tube 84 meshes with worm 95 andsaid tube israised or lowered inits companion tube 83in accordance with the direction of travel of the worm 95. A sleeve'90, having i jaws, is keyed and locked to thetop of shaft 89 'and is in line with an upper shaft 89', which is provided at its bottom with a sleeve 92, having jaws and being adjustably keyed to shaft 89 to permit its. sliding in a vertical direction. A helical spring 93is seated on "top of sleeve 92 and-extends about shaft 89' in the tubular casing 91 which is adjustably. mounted on sleeve 9.0.
