Abstract
Abstract An earth boring machine having a power head including an auger drive shaft movable toward and away from the ground and having means for tilting the auger shaft for boring holes at various angles relative to the vertical. A single prime mover on the machine operates to impart movement thereto over the ground, tilt, raise, and lower the power head, and rotate the drive shaft, selectively, by means of transmission and control mechanisms.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
317 words
A mobile earth-boring machine comprising: a. a normally horizontal base frame having front and rear ends and laterally spaced sides; b. supporting and driving wheels operatively journaled at the opposite sides of said base frame; c. an elongated normally upright guide member having a flat plate-like rear wall; d. a power head including a rotary drive shaft generally parallel to the longitudinal dimension of said guide member; e. means including a cradle means mounting the power head on said guide member for movements longitudinally of said guide member; f. elevating mechanism for imparting said movements to the power head; g. a prime mover mounted on said base frame; h. power transmission mechanism operatively connected to said prime mover for imparting driving movement to said wheels, elevating movements to said elevating mechanism, and driving rotation to said drive shaft; i. control means for said transmission mechanism operative to control driving movement of said wheels, elevating movement of said elevating mechanism, and rotary movement of said drive shaft, selectively; and j. means mounting said guide member of said base frame for universal swinging movements in forward, rearward and sideward directions relative to said base frame and comprising: 1. a generally upright plate-like standard having a lower end hinged to the front end of said base frame on a horizontal axis extending transversely of the base frame; 2. means pivotally mounting said guide member rear wall in face to face engagement with said standard for swinging movements of said guide member on an axis normal to said horizontal axis; 3. clamping means operatively associated with said standard and rear wall for releasably locking said guide member in desired set positions for swinging movement thereof relative to said standard; 4. stop means positively limiting said swinging movements of the guide member relative to said standard; and 5. means for imparting limited swinging movements of said standard relative to said base frame.

Claim 3
Dependent Claim
31 words
means pivotally mounting said guide member rear wall in face to face engagement with said standard for swinging movements of said guide member on an axis normal to said horizontal axis;
Claim 4
Dependent Claim
31 words
means pivotally mounting said guide member rear wall in face to face engagement with said standard for swinging movements of said guide member on an axis normal to said horizontal axis;
Claim 5
Dependent Claim
140 words
The mobile earth-boring machine defined in claim 1 in which said elevating mechanism comprises an elongated flexible link chain having opposite ends each anchored to a different end of said guide member, a fluid pressure operated elevating motor mounted on said cradle and having a rotary shaft, and a chain engaging drive sprocket wheel on said rotary shaft, characterized by a pair of idler wheels journaled in said cradle in spaced apart relationship longitudinally of said guide member and disposed to engage said link chain, said drive sprocket wheel being disposed in laterally offset relationship to said idler wheels so that said chain runs from one of said idler wheels generally transversely of said guide member in one direction to and over said drive sprocket wheel, and from thence in the opposite direction to the other of said idler wheels.
