UNITED STATES GEORGE A. KNAPP, OF SPQKANE, WASHINGTON.

DETACHAIBLE can srour.

Application filed January 26, 1926. Serial No. 83,931.

This invention relates to improvements in detachable spouts for cans for fac1l1tat1ng egress of liquid contents therefrom.

The device of my invention is generally L-shaped and it is a novel feature to provide the same with a tapered piercing limb whereby the can top may be readily pierced to permit partial insertion of the spout therein.

It is a feature of my invention to form the reinainingilimb as a pouring limb, the same being provided with pouring and air vent passages of a novel formation to facilitate egress of the liquid contents.

It is also a feature of my invention to provide means for effectively sealing the can after the device of my invention has been applied thereto so that evaporation will be reducedto a. minimum.

In this connection, it is a feature of my invention to provide means forcausing one or more portions of the device to positively engage the can when secured thereto for the purpose of rigidly holding the device in position.

My invention'has many other features and objects that will bemore fully described in connection with the accompanying drawing and whichwill be more'particularly pointed out i in and by the appended claims.

In thedrawing 5- y 1 ,Fig. 1, is a view in section of a can and showing how the device of my invention is inserted therein. r

Fig. 2, is asimilar view after the device ;hasbeen inserted and before the same has been secured in an inserted position.

Fig. 3, is a view showing the device secured in a fixedv position. i i

Fig. l, isa plan view thereof with the closure omitted.

Fig. 5, is a sectional view of the spout detachedfrom its associated parts. 1

Like characters of reference designate similar parts througl'iout the different figures of, the drawing.

The device of my invention includes a substantially L-shaped spout having a. pierc-.

ing limb 1 and a pouring limb 2. The piercing limb l tapers from what I will-term its juncture end 3, toa sharply pointed piercing end 4. As will be seen by reference. to Fig. 5, the piercing limb is slightly arcuate, which form disposes the sharp end or terminal 5-, at a sufficient elevation with the mid-center portion 6, to insure engagement of the terminal 5, with the under face 7, of the top *8,

of the can 9, when the device is in a final tightened adjustment, as shown in Fig. 3.

The end 4, is preferably solid, but the limb IS hOllOW as indicated at 10, from the solid portion toward the juncture end 8,to form an air vent passage. The discharge outlet for said passage is indicated at 11, and the same opens through the periphery of the prong and preferably upwardly with respect thereto in a manner to freely communicate with theinterior of the can. It is also a feature of my invention to make the limb 1, relatively elongated thereby affording a sulficient leverage in order to render it more effective in stabilizing the spout, as will be more fully described.

The remaining orpouring limb designated at 2, joins the piercing limb 1, atan elbow or juncture, and I preferably make the pouring limb of slightly less diameter than the larger cross section of the piercing limb so that a substantial shoulder 12, will be formed, the main function ofwhichis to bend double the mutilated portions of the can resulting from the piercing operation. This affords a better engagement ofthe spout with theperforated top of the can, as will later appear, although this is not an essential feature of my nventlon.

The pouring limb, 2, is tubularand preferably cylindrical and its upper 'openend 13, is inclined as shown to facilitate pouringof the liquid contents of the can. I have shown the pouring limb partitioned off as by a partition 14, which functions to divide the limb into an inner air vent passage 15, communicating with passage 10, and an outer pouring passage 16. The pouring passage 16 has an intake at 17, disposed below the top 8,. of the can and always tin-obstructed to ingress of the liquid contents.

It is a feature of my invention to provide the device with means whereby not only a. tight, closure of the can may beeffected,' but which means alsoc performs the additional function of causing a portion of itself and aportion of the spout to so engage the can as to stabilize the device there on when said device is attached thereto, which means I will next describe in, detail.

On the pouring limb 2, is a. cam lug 17. A cam sleeve 18, is rotatively adjustable on said limb 2, and has a cam edge19,adapted for coaction with lug 17. I dispose a yield ing washer 20, about limb 2, and preferably upon this washer is a metal washer 21, the

latter being adapted not only to take the wear but also to distribute the compression of washer 20. The cam sleeve 18, has an actuator 22 which is preferably winged shaped, and which forms, as shown, a continuation of said sleeve 18. In order to render said sleeve easily attachable and detachable to and from limb 2, I terminate one edge or end 23, thereof, siort of a complete circle whereby the sleeve can be slipped on and off from the end of limb 2. Said actuator 22 has a lower edge 2%,adapted to engage the top of the can 9, and to its upper edge 25, is pivoted. at 26, a spout closure 27, having a handle lever 28. A spring 29, serves normallyto seat said closure 27.

1 The operation of my device is as follows The limb 1 is inserted as shown in Fig. 1, until it has reached an inside position in the can, whereupon, it is shifted into the position shown in Fig. 2. When the device is in the Fig. 2, position, it is not only unstable but it is loosely disposed in the can top 8. Next, the actuator 22, is turned from the Fig. 2 to the Fig. 3, position, the turning movement being clockwise, viewing Fig. 41. This adjustment of the actuator 22, causes edge 19 to coact with lug 17, and elevate the device to the position shown in Fig. 3, wherein the end 4 is in engagement with the top 8, and the enlarged shoulder 12, fits snugly in the opening pierced by the limb 1. The edge 24, of the actuator 22, bears downwardly on top of the. can in opposition to end 5, and between the end A, and shoulder 12. Irrespective of the shoulder 12, the bight 30, and end 4,. would afford spaced .points of contact or engagement, with the top of the can in the absence of the enlarged juncture of the limbs. Thus, I not only obtain a substantially air tight closure of the can, but I also obtain a very rigid detachable connection therewith.

Now as the can is tilted, in the usual way, the liquid contents can egress from passage 16, and the air will ingress through 15 and .10 and discharge into the can through opening 11.

It is believed that the device of my invention will be fully understood from the foregoing description and while I have herein shown one form of my invention, I do not wish to be limited thereto except for such limitations as the claims may import.
