- drawiugs- A represents the stock of my hit, conical toward the point a, which is provided with a cutting-lip, b.
- b B is a spur, of the form generally attached to centerits.
- C is the cutter, which is a halt' convolution of a screw about the stock.
- the point being provided with the cutting-lip cuts its passage as it advances, and is not to be forced into Y the Wood, as is the case with auger and center-bits.
- the point of the spur circumscribes the bore, and gauges the depth of cutterfollowiugit, while the latter being but of suici'ent length to feed down the tool, and to carry back the chip, the'boring is effected with the least friction and perfect truth.
- the spur may be in the form of a partial convolution of a screw about the stock, it' desired, or it may extend the full length ofthe stem.
Description
@wat @Win12,
DANIEL KNEL-LY, OF MUSKEGON, MICHIGAN.
Letters Patent No. 102,829, dated May 10, 1870.
IMPROVEMENT IN BORING BITS;
The Schedule referred to in these Letters Patent and making part of the same.
To whom Iit 'may concern:
Be it known that I, DANIEL KELLY, of lMuskegon, in the county of Muskegon and State of Michigan, have invented a new and useful Improvement in Boring-Bits; and I do declare that the following is a true and accurate description thereof, reference beingv posite side with a cutter formed of a half convolution of a screw; also, in providing the elongated point with a cutting-lip, the whole brming a more durable hit than any now in use, and easier to opera-te.
In the drawiugs- A represents the stock of my hit, conical toward the point a, which is provided with a cutting-lip, b. b B is a spur, of the form generally attached to centerits.
C is the cutter, which is a halt' convolution of a screw about the stock.
The point being provided with the cutting-lip, cuts its passage as it advances, and is not to be forced into Y the Wood, as is the case with auger and center-bits. The point of the spur circumscribes the bore, and gauges the depth of cutterfollowiugit, while the latter being but of suici'ent length to feed down the tool, and to carry back the chip, the'boring is effected with the least friction and perfect truth.
It will readily be seen that this bit will last or wear longer than either the center or auger-bit, as the cut# ter of the former and screw-point ofthe latter will not permit of much filing. v
The spur may be in the form of a partial convolution of a screw about the stock, it' desired, or it may extend the full length ofthe stem.
What Iclaim as my invention, and desire to secure by Letters Patent, isi A hit, having a conical point, a, provided with a cutting-lip, b, and its stock A, with aspur, B, and cutter C, the latter in the form of a partial convolution of a screw-thread about the stock, substantially as described.
DANIEL KELLY;
Witnesses H. J. HOYT, GHAs. C. CHAMBERLIN.
