TAP FOR DRAWING OFF LIQUIDS FlROlVl TlNS.

Specification of Letters Patent.

Patented Oct. 1'7, 1905.

Application filed March 30, 1903. Serial No. 150,121.

To all whom it may concern:

Be itknown that I, GEORGE HELLEUR, asubject of His Majesty the King of Great Britain and Ireland, residing at Pahiatua, in the Provincial District of Wellington, in the Colony of New Zealand, have invented new and useful Improvements in and Relating to Taps for Drawing Off Liquids from Tins, of which the following is a specification.

The object of this invention is the provision of a tap which can be readily attached to a receptacle such as is commonly employed for holding kerosene.

In my invention the screwed stem of the tap is made integral with or has fixed upon it a cutter which is caused to pierce the sheet metal of the receptacle and form a hole to receive the stern of the tap which is screwed into said hole.

In the drawings accompanying this specification, Figure 1 is a side sectional elevation of a tap, and Fig. 2 a similar View showing the tap attached to a-receptacle.

The tap has a barrel 1, preferably of wood, fitted with a hollow metal plug 2, operable for withdrawal of liquid from a receptacle. In the end of the tap is screwed the tubular metal stem 3, screw-threaded throughout its length and provided at its end with the projecting end 4. The cutter shown in the drawings is preferably of steel and resembles the nose of a boring-bit. The cutter is integral with the projecting end 4 and is made by cutting away the part 6 until a sharp point 7 is formed and a cutting edge 8 is formed longitudinally along the sloping rim of the central hole 9'. The hole made by the cutter is of the same diameter as the stem at the bottom of the screw-thread, and in operation the stem is screwed into the hole, forming its own thread as it enters.

A washer 5, of cork, is threaded upon the stem and makes a liquid-tight joint between the tap and the receptacle.

I am aware that faucets have been provided with means for piercing a hole in the can to which the faucet is to be applied and with means for making a liquid-tight joint. In the patent of James H. Lord, No. 105,818, dated July 26, 187 0, such a faucet is described. Therein a hollow auger makes the hole in the can and is then passed completely through the Wall of the can into the interior thereof, a

back nut upon the stem of the tap being employed to clamp the wall of the receptacle between the vertical back face of the auger and an elastic washer threaded upon the stem of the faucet. In my invention the stem of the tap is parallel, not tapering like an auger, and the cutter integral with the screwed stem forms a hole in the wall of the receptacle of diameter equal to that of the stem at the bottom of the screw-threads thereon. The action of screwing the stem of the tap into the material of the can clamps the washer against the face of the can, no back nut being required to insure a perfectly fluid-tight joint.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

For the purpose indicated in combination a tap, a tubular metal stem screw threaded throughout its length adapted to screw into the tap at one end and having a hole throughout its central axis, acutter integral with the opposite end of the stem comprising a mutilated end terminating in a point and a cutting edge formed longitudinally along a sloping rim of the central hole, as specified.

In witness whereof I have hereunto set my hand, in the presence of two witnesses, this 26th day of February, 1903.

GEORGE I-IELLEUR.
