lnitrd A (lteres @anni @imita Letters Patent No. 111,167, dated January 24,1871.
IMPROVEMENT 'lN HQLLOW AUGERS.
The Schedule referred to in these Letters Patent and making part o the same.
To all whom it may concern Be it known that we, AARON BAUMAN and Orrin O. WITHERELL, of Toledo, in the county of Lucas and `State of Ohio, have invented a new and useful Improvement in Hollow Angers; and we do hereby de-V clare that the following is a full, clear, and exact description thereof', which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specication, in whichv Figure'l is a longitudinal section of our improved hollow anger.
Figure 2 is a front end view of the Sallie.
Similar letters of reference indicate `corresponding parts. Y
Our inventiony lhas for its object to furnish an improved hollow auger, which shall he simple and inexpensive in construction, not liable to get out of order, and which shall require less power to operate it than the hollow angers constructed in the ordinary manner.
And it consists in the construction and combination of various-'parts of the machine, as hereinafter more fully described. p
A is the hollow cylinder, which revolves in hearings B, and which is revolved by power applied to the pulley O, attached to ysaid cylinder. l
To the forward end of the cylinder A is attached a cutter-head, D, which is provided with three bit-s or cutters d1 d2 f d, the two foremost ones, LZ1 d2, of which out thewood away, le( ving a central core, which serves as a guide to the auger to keep it in line and prevent it from following the grain of the wood. After the core has served its purpose as a guide, the third bit d3., following the other two, cuts the `core away, so that it may not obstruct the chips or cuttings in their passage from thecylinder.
lhe operation of the cutters is assisted, and the chips or cuttings are blown from the' cylinder A by steam, which is discharged in the forward end of the cylinder A, to act upon the wood being' cut, and s'often it softhat the auger may .cut faster and leave smoother hole, and at the same time the steam blows the chips or cuttings from the cylinder, and thus prevents'it from becoming clogged.
The' steam is introduced through the half-round or concavo-convex pipe E, which passes along the lower side of the interior of the cylinder A, and is held stationary while the said cylinder revolves; the edge of the said pipe E, from its peculiar shape, thus clear'- ing o" the chips from the sides of the said cylinder while allowing a large space for the escape of said chips.
Upon the forward end of the pipe E is formed a point, c',- which, from its* position just in the rear of the bits d*l d2 d, stirs up the chips and prevents them from clogging the augert The chips :are thus kept light and free, so that they may readily pass from the cylinder.
Having thus described our invention,
We claim as new and desire to secure by ALetters Patent- 1 The arrangement, upon a rotary stock D, of the front hits Z1/rl?, and rear bit d, as and for the purpose specified.
2. The arrangement, With respect to'the tools, and near the internal surface of the revolving hollow shaft, ot' the separate and independent steam-pipe E. 'to discharge the chips in the manner described.
3. As au improvement in pipes for injecting steam4 l into a hollow' auger-shaft, the arrangement on the end thereof, and with respect to the tools, of the point e', to stir up the chips and prevent them .from clogging the auger. y l

ORIN O. WITHERELL.
