Application 1ed September 7, 1918. Serial No. 252,994.

To all whom it may concern:

Be it known that I, WILLIAM E. MOORE, a citizenl of the United States, residin at Chicago, in the county of Cook and tate of Illinois, have invented certain new and useful Improvements in Earth-Boring Machines, of which the following is a specification.

This invention relates to earth boring machines.

The invention is particularly applicable to power operated earth boring machines of the mobile type.

One of the objects of the invention is to provide an improved earth boring machine.

Another object is to provide an earth boring machine which may be readily controlled.

Another object is to provide an earth boringmachine wherein the boring tool is rotated, raised and lowered, positioned relative to the work, and inclined by a common source of power and without danger of interference.

Another object is to provide an earth boring machine having improved operating and controlling mechanism.

Another object is to provide a mobile earth boring machine wherein the boring auger may be readily positioned above the work.

Another object is to provide an earth boring machine wherein the auger is rotated and driven to the work by a common source of power and wherein the operations are independently controlled.

Another object is to provide an earth boring machine which is efficient and reliable.

Other objects and advantages ofthe invention will appear from the specification and claims.

An embodiment of the invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of an earth boring machine.

Fig. 2 is a top plan thereof.

Fig. 3 is a rear elevation.

Fig. 4 is a section on the line 4 4 of 5 is a section on the line 5-5 -of Fig. 7 is a section on the line 7-7 of Fig. 2.

. he earth boring machine has a frame 1()A and wheels 11 forming the chassis of a vehicle. Chassis frame 10 vsupports aturntable 14. Upon turntable 14 is mounted the operating motor, auger tower and transmission and control mechanism whereby the motor supplies the power for producing the desired operations of the boring, auger and the operations thereof are controlled.

Rigidly secured to chassis frame 10 is a gear wheel 12, through which the turntable is rotated, and a circular track 13, upon which the turntable is mounted.

The turntable is pivoted to chassis frame 10 by a stud or shaft 15 which is rigidly secured to the frame and passes axially through gear wheel 12. vThe frame of the turntable is composed of two side bars 150, end member 16 and transverse stays 17. These members may be made from channel iron. Secured to the bottom of the frame is an annular turntable support or track 18. Support 18 is formed of parallel facing channel bars to which are secured a number of journaled rollers 19.. Rollers 19 rest upon track 13 and convey thereto the weight of the turntable and the apparatus carried thereby and upon these rollers the turntable may be rotated.

Mounted on one end of turntable 14 is a motor 20, such as a gasolene engine. Engine 20 has a shaft 21 which is connected to a mainshaft 22 of the transmission mech` anism by a sprocket wheel andchain connection 23. Main shaft 22 is located longitudinally intermediate the ends of -turntable 14 and extends entirely across the same.

From main shaft 22 power is taken for rotating the turntable to position the auger relative to the work, for rotating the auger to effect the boring operation, pfor-raislng and lowering the auger and for tilting the auger to produce inclined holes or move the auger to carrying and operating positions, ete. I f

Ro tat'lag turntable.

reverse direction through an intermediate shaft 26. Rotatably mounted upon shaft .25 is a sleeve 27 to 'which is rigidly connected the cu of a clutch 28 and a sprocket wheel 29. n endless chain 30 interconnects sprocket wheel 29 and a sprocket wheel 31 keyed 'to shaft 22. The cone 32 of clutch 28 is mounted to slide upon and rotate shaft 25. ,Cone 32 is moved along shaft 25 into and out of driving position by a lever 33, which is operated through a link 34 and a rod 35 by an operators lever 36.

Shaft 26 is provided with a sleeve 37 rotatably mounted thereon. Sleeve 37 has rigidly secured thereto the cup of a clutch 38 and a sprocket wheel 39. Sprocket wheel 39 is interconnected by an endless chain 40 with a sprocket wheel 41. Sprocket wheel 41 is keyed to main shaft 22. The cone 42 of 4clutch 38 is adapted to slide upon and rotate shaft 26. Cone 42 is moved into and out of driving position by a lever 43 which is secured to link 34 by a pivot 44. Clutches 28 and 38 are therefore simultaneously operated by operators lever 36. The relation of the clutches is such that both may be in non-driving position at the same time, when the turntable is to be held relatively stationary and one or the other, but never both simultaneously may be in driving position to rotate the turntable in the desired direction.

Shaft 25 drives shaft 24 through meshing gear wheels 45 and 46, keyed to the respective shafts. Shaft 26 drives shaft 24 through sprocket wheels 47 and 49, keyed to the respective shafts and interconnected by an endless chain 48. Shaft 24 is thus driven in one direction by shaft 26 and in the opposite direction by shaft 25.

A beveled gear wheel 50 is keyed to shaft 24. Gear wheel 50 meshes with a beveled gear wheel 51 keyed to a shaft 52 which also carries a pinion 53 meshin with gear wheel 12.' Consequently when s aft 24 is driven ineither direction pinion 53 rotates upon and about the stationary gear wheel 12 and the turntable is accordingly rotated.

If, for example, the turntable is to be turned to the right, operators lever 36 is moved to throw in clutch 28. The turn table is then rotated by the engine through chain 23, shaft 22, chain 3,0, clutch 28, gear wheels 45 and 46, shaft 24, ear wheels 50 and 51, pinion 53 and gear w eel 1.2.

When the turntable is to be stopped lever 36 is moved to mid-position wherein both clutches 28 and 38 are thrown out of driving position. y

To reverse the direction-of movement of the turntable, operators lever 36 is moved to the opposite position. Thereupon clutch 38 is thrown in and the engine rotates the turntable through chain 23, shaft 22, chain` 40, clutch 38, chain 48, shaft 24, gear wheels 50 and 51, pinion 53 and gear wheel 12.

The turntable may therefore berotated in either direction upon the manipulation of a single lever readily accessible tomthe operator. T he relation of the clutches pro-vides a positive safety arrangement for preventing both clutches from being thrown in simultaneously which might result in broken gears, sprocket wheels, chains, shafts, or other parts of the structure. The proper operation of the turntable is thus insured and theauger may be readily and quickly positioned above the work.

Rotating auger.

The auger is rotated always in the same direction by the engine and the loperation may be started and stopped by the manipulation of a single lever.

Shaft 22 has rotatably mounted thereon a sprocket wheel 80. Sprocket whel 80 is rigidly secured to the cup 81 of a clutch 82. Cup 81 coperates with a clutch cone 83 which is adapted to slide longitudinally upon and be rotated by shaft 22. A lever 84 is Asecured to cone 83 and acts to force the cone into and out of engagement with cup 81. Lever 84 is actuated through a rod 85 by an operators lever 86.

An endless chain 87 interconnects sprocket wheel 80 and a sprocket wheel 88, which is (See particularly Figs.

located in a gear box carried by thel lower end of the auger tower.

An auger or boring tool 104 is carried on the end of an auger shaft 103. Shaft 103, which has a square cross section throughout the greater portion of its length, passes through a square opening in a sleeve or 'bushing 110 of gear wheel 109. Shaft 103 is adapted to slide through the opening in sleeve and gear wheel 109, Abut is rotated `when gear wheel 109 revolves.

Raising amd lowering wager.,

Theauger is lowered and raised or driven to and from the work by the engine and its up and down movement is independent of the rotation so that these operations may be independently varied to best suit the conditions of the work.

Keyed to shaft 22 is a bevel gear wheel 54. Gear wheel 54 meshes with a bevel gear wheel 55 keyed to the end of a shaft 56 journaled in a bearing 57. Surrounding shaft 56 is a sleeve 160. Sleeve 160 is feathered to shaft 56 so as to be adapted to slide upon but be rotated thereby. Sleeve 160 is journaled in a collar 161 movably carried in a thrust bearing 58 and thus supports one end 0f shaft 56. Rigidly mounted upon sleeve 160 are a pair of facing bevel gear wheels 59. Gear wheels 59 are adapted to engage either of two facing bevel gear wheels 60 and 61. Collar 161 has a pin 162 extending through a spiraled slot 163 in bearing 58 and carries a lever 164. When lever 164 is rotated collar 161 is turned and the coperating pin and s-lot move sleeve 160 and gear wheel 59 to the right or left, as viewed from Figs. 1 and 2, depending upon the direction of rotation. v

The position of gear wheels 59 relative to gear wheels 60 and 61 is controlled by a lever 77 which moves lever 164 and is interconnected by a rod 78 with an operators lever 7 9. i

Gear wheel 61 is keyed to the end of a shaft 63. A sprocket wheel 72 is rotatably journaled on shaft 63 and carries a cup 73 of a clutch 74. Clutch 74 has a cone 75 keyed t0 slide upon and rotate with shaft 63; Clutch 74 is thrown into and out of driving connection by a lever 76 interconnected by a rod 70 with an operators lever 71.

Sprocket wheel 72 is interconnected by an endless chain 90 with a sprocket wheel 91 carried by a sleeve 92 which is journaled upon shaft 89. Sleeve 92 has a sprocket wheel 93 rigidly secured thereto. Sprocket wheel 93 is interconnected with a sprocket wheel 94 by an endless chain 95. Sprocket wheel 94 is keyed to a shaft 96 journaled in bearings carried by the auger tower.

The auger tower comprises four posts 100 of angle iron, rigidly secured at their bottoms to a gear box 105. Gear box 105 is journaled on opposite sides upon the turntable by shaft 89-and a'trunnion 111, which have suitable bearings supported by the turntable framework as shown in Fig. 6. Posts 100 carry a pair of longitudinally extending guides 101 which provide ways for the opposite sides of a slidin cross-head 102. Head 102 has journaled t erein a circular cross sectioned portion of auger shaft 103, whereby, when the head is moved up and down in the tower, the auger shaft and auger are raised and lowered. The head and its guides brace the upper end of the auger shaftv so that the same is securely retained 1n proper position within the tower and is protected against objectionable deflection.

Head 102 has a lug or clamp to which is secured lan endless chain 112. Chain 112 passes over a sprocket wheel 113 journaled at or near the top of the tower and a sprocket wheel 114 keyed to shaft 96. Thus- Wheel 72, chain 90, sprocket wheel 91, sleeve 92, sprocket wheel 93, chain 95, sprocket wheel 94, shaft 96 and sprocket wheel 114 and chain 112. y

To move the auger in the reverse direction, operators lever 79 is thrown to the reverse position, whereupon the right hand gear wheel 59 engages gearwheel 61 (see The direction of rotation of shaft 63 is thus reversed and consequently the movement of the auger shaft and auger 1s reversed.

Tilting auger' tower.

The auger is tilted or inclined by the engine and the tilting movement may be controlled by a single lever.

Gear wheel 60 is keyed to a shaft 62 which has journaled thereon a sleeve carrying a ear wheel 64v and a cup 65 of a clutch 66. lutch 66 hasa cone 67 adapted to slide upon but rotate with shaft 62. Cone 67 is provided with a lever 68 which is connected to rod by a link 69. Consequently when operators lever 71 is actuated, it movesI cone 67 into an out of driving connectionV with cup 65. The relation of clutches 74 and 66 and their operating connections are such that when one clutch is moved to driving position the other clutch is simultaneously moved out of driving position. Thus it is impossible to raise or lower the auger while it is being tilted and vice versa.

Gear-wheel 64 meshes with a pinion 115 towhich is secured a sprocket wheel 116. An endless chain 117 interconnects sprocket wheel 116 and a sprocket wheel 118. Sprocket wheel 118 is keyed to a shaft 119 which also has keyed thereto a bevel pinion 120. Pinion 120 meshes with a bevel pinion 121, keyed to the end of a short vertical shaft 122. Shaft 122 carries a worm 123 adapted to engage a segmental rack 124. Through rack 124 the tower is tilted -about a horizontal axis provided by shaft 89'and trunnion 111 on gear box 105. Rack 124 is rigidly secured to a frame 125 which fits' on one side, are t ereby lessened.

tower mounte When the tower is to be tilted to a position to bore an inclined hole or for ready transportation, lever 79 if not already in position to cause the en agement of gear wheel 60 and the require gear wheel 59, is moved and then clutch 66 is actuated by operators lever 71. Lever 71 insures that clutch 74, controlling the up and down movement of the1 auger, is thrown out of driving position before clutch `66 is thrown into driving position.

Thus if lever 79 is in one position and clutch 66 is thrown' into driving position, the auger tower and auger is rocked or tilted by the engine through sprocket chain 23, shaft 22, gear wheels 54 and 55, left hand gear wheel 59, gear wheel 60, shaft 62, clutch 66, gear wheels 64 and 115, sprocket wheel 116, sprocket f chain 117, sprocket wheel 118, shaft 119, gear wheels 12() and 121, shaft 1,22, worm 123 and rack 124.

Throwing operators lever 7 9 to the reverse position will move gear wheels 59 so that the right hand gear wheel will engage gear wheel 60. The direction of rotation of shaft 62 will be reversed and the tower will be tilted in the opposite direction.
