` Letters Patent No. 86,956, dated Febwm'y vlo, 1869.

ILIPRQVEMENT IN BORING-FAUCETS The Schedule referred to 1n those Letters Pat'ent and making parl: of the same.

ro all whom t ma/y concern Be it known that I, ALFRED WEED, of Boston, in the county of Suolk, and State of Massachusetts, have invented an Improvement in Self-Boring Faucets; and I do hereby declare that the following, taken in couneotion with the drawings which accompany and form part of-thisspecifcation, is a description of 'my invention, sufcient to enable those skilled in the artto prac-v tise it.

My improvement relates to the construction of that class of faucets, the entering end of each of which is provided With a bit for boring the hole into which the faucet is driven or screwed, to attach it to the cask.

' Such a faucet is shown in United States Letters Patent, No. 7 8,499, granted to me, June 2, 1868.

In such patented faucet, and in all other self-boring faucets with 'which I am familiar, the boring-device is made of steel, and when the bit is Within the barrel,

(to which the faucet may be applied,) the steel quickly oxidizes, and causes the cutting-edges thereof to be ruined.

To remedy this and The improvement consists in making the bit of a self-boring faucet of metal which is practically unoxidizable, or oxidize's so slowly as not to be injured by is the object of my improvement;

contact with the contents of molasses-casks, and other c, the valve-stem;

d, the induction-orifices;

e, the .entering bit;

f, the handle, by means of which the bit is turned irl-boring; and

g, the screw-thread upon the faucet-tube, by means of which the faucet is confined to the cask.

The bit e is sb'own as having a centre-gimlet point,

h, a side spur or cutter, i, and a chip-cutter, k, and it will be observed that the chip-cutter has nospur-cutter at its end, the spur being on the opposite side of the entering point h, this construction not only enabling the cutter It to be readily sharpened, but enabling the faucet to be turned more readily in` boring, as the chips .raised by the cutter k do not clog against the spur-cutter fi. The faucet-body a is preferably made of cast-iron for the purpose of cheapness; but the bit e, I make of brass, bell-metal, or some other composition of copper and tin, (preferably cast,) this composition-bit being fixed to the end of the faucet-tube, the same as a steel bit would be.

The composition-bit thus applied is cheaper than a steel bi-t, cuts with perfect freedom, preserves 'its cutting-edges Well, and does not readily oxidize, or become impaired (as regards its boring-capability) by oxidation.

I claim the described self-boring faucet, having a bit riveted thereto, and having the parts 71. t k, formed of composition-metal, all substantially'as and for the purpose described.
