'CONDUI'I DEVICE FOR TAPEING CANS.

Application filed May 4,

tween the receptacles and the conduit de vices and the object of my improvement is' to provide simple and eificient means by which an outlet conduit as a faucet, may be tapped into and secured by a rigid leak proof connection to aclosedreceptacieof thin metal without having access to the inside of said receptacle.

The invention consists in the novel construction, adaptation and combination of parts as will be more clearly hereinafter described and claimed.

In the accompanying drawings Figure 1 is a View in side elevation of a faucet that is equipped with devices constructed in accordance with my invention, certain of such devices bemg shown in cross section and a fragment of a receptacle to which the fancet is connected being shown in cross sec tion. 7

Fig. 2 is a view partly in section and partly in elevation substantially on broken line 2, 2 of Fig. 1.

Fig. 3 is a view partly in section and partly in elevation substantially on a broken line 3, 8 of Fig. 1, the receptacle being omitted.

Fig. 4 is a fragmentary view in elevation of a receptacle that hasa hole and a slot cut therein preparatory to applying the faucet shown in Fig. 1 thereto.

Fig. 5 is a fragmentary view in perspective of the same receptacle showing the metal adjacent the slot bent outwardly in a suitable position to engage within a groove on a knob on the end of the faucet.

Referring to the drawings, throughout which like reference numerals designate like parts, the numeral 6 designates a faucet of ordinary construction that is provided with a threaded shank 7 which is adapted to be Specification of Letters Patent.

connected with any suitable receptacle or conduit from which liquid is to-be drawn off.

The end of the shank 7' has a relatively large knob or head 8 rigidly secured thereto which head 8 is rounded on its outer side and is flat on its inner side to form an annular shoulder 10. The head 8 is provided with a spiral slot or groove 11 that is cut entirely through such head and preferably extends from the periphery thereof inwardly in spiral fashion and intersects the shank? at a. point substantially ninety degrees from the point of beginning.

The head 8' may be screwed onto the end of the shank 7 until its outer surface is flush with the outer end of the shank and may then be soldered or brazed thereon to prevent it from turning. 8 is put onto the shank, a nut 12, a metal washer 13 and a hard rubber or fiberw-asher- 14 are placed on such shank 7 in the order named so that the rubber or fiber washer.

14 will bear against the side of a tin or sheet metal container 15 when the nut 12 is tightened in the final position as shown in Fig. 1. V

"Thecontainer 15 is prepared for the reception of the faucet by cuttin therein a cylindrical hole 16 of just large enough diameter to fit over the shank 7 then cutting a slot 17 outwardly from the hole 16, a dis tance equal to substantially the width of the flange or shoulder 10 and then bending the metal at one side of the slot 17 outward slightly as shown at 18 in Fig. 5. I

In inserting the head 8 through the hole 16 such head is placed againstthe outside Before the head of the hole with the outwardly bent portion 18 of metal inserted-a slight distance into the groove 11 and the head is then turned in the proper direction to cause the bent portion of metal 18 to pass into and through the groove 11 and the head to pass entirely through the hole 16. As the head 8 passes through the hole 16 the metal at the two sides of the slot 17 will necessarily be bent so that it will. leave an opening somewhat larger than that shown in Fig. 5 but when the nut12 is tightenedas shown in Fig. 1 the bent portions will be bent back into their original positions and the metal of the container will be tightly clamped between the washer l and the head 8 thus forming a liquid tight connection. The

washer 14c will preferably be of slightly larger diameter than the head 8.

In removing this device from a can or receptacle the nut 12 is loosened, one of the edges of the metal adjacent the slot 1'7 is bent inwardly enough so that it will engage within the slot 11 in the head 8 and the faucet is turned far enough to permit the head to pass out of the hole 16.

In inserting the faucet in a closed ca that is full of liquid, as oil, the can will preferably be laid on its side and the hole 16 cut in the uppermost side of the can near the bottom thereof. After the faucet is inserted and the nut 12 tightened the can may be strightened up and the faucet used in the usual manner to draw off the liquid.

In practice the spiral groove 11 will pref erably be at the uppermost portion of the head 8 and the slot 17 will preferably intersect the bottom of the hole 16 so that the groove 11 and slot 17 will not be opposite each other in the final position.

The invention is shown as applied to a faucet but it will be understood that the shank 7 may be any cylindrical member either solid or tubular.

From the above description taken in connection with the accompanying drawings the advantages of the construction and of the method of operation of my invention will be readily appar nt to those skilled in the art to which the same relates, but, while I have described the principle of operation of the invention together with the device which I now consider to be the best em bodiment thereof, I desire to have it understood that the device shown is merely illus trative and that such changes may be made as are within the scope of the following claims.

What I claim is 2-- 1. The combination with a plate of flexible material having a circular hole therein and provided with a slot that intersects said hole, of a cylindrical shank adapted to be inserted in said hole, and a head on said shank, said head being of larger diameter than said hole and having a groove extending spirally from the outer to the inner surface thereof and arranged to permit the passage of the material around the circumferenceof said hole whereby said head may be passed through said hole.

2. Apparatus of the class described comprising a closed receptacle of thin flexible metal having a circular hole therein and provided with a slot that intersects said hole, a tubular shank adapted to fit snugly within said hole, a head on said shank, said head being of larger diameter than said hole and being convex on its outer surface and plane'on its inner surface and said head having a groove extending spirally therethrough from the plane inner surface to the convex outer surface and arranged to permit the passage therethrough of material surrounding said hole whereby said head may be passed through said hole by turning the same, and means on said shank for clamping the metal around the circumference of said hole against the plane side of said head.

. In witness whereof, I hereunto subscribe my name this 29th day of April, A. D. 1920.
