UNITED STATES PATENT OFFICE.

WALTER LUNSFRED WHITESIDES, 0F LONG BEACH, CALIFORNIA.

DETACHABLE can sron'rl Application filed November 18, 1924. Serial No. 749,751.

To all whom it may concern Be it known that I, WALTER L. WHITE- SIDES, a citizen of the United States, residing at Long Beach, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Detachable Can Spouts; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to readily attachable and detachable pouring spouts for numerous kinds of cans, and the invention is intended primarily for use upon evapo-' rated milk cans. A similar article was patented by me on April 29, 1924, under Patent No. 1,492,501, so that it is the primary object of the present invention to'provide a simplified device which may be easily made at less cost than the device disclosed by such patent.

Iemploy a tube which is adapted to be forced through a can top or other wall and then turned to interlock with such wall, and to tightly engage the outer side of the can. I provide a gasket which is held in place by a continuous ring surrounding the tube. A further object is to provide a novel ar rangement of wings extending from the ring to the tube, said wings serving as fingerpieces for turning the tube and also acting to relatively brace the tube and the ring.

One end of the tube is obliquely cut and is provided with an external sharp-edged longitudinal rib to be forced through the can, and a further object of the invention is to so locate the rib'as to have its inner end constitute a shoulder-for engagement with the inner side of the can wall, after the tube has been forced through such wall and turned, the shoulder then serving to effectively retain the device in place.

Fi res 1, 2 and 3 are side elevations of the evice looking in different directions and showing it engaged with the top of a can.

Figure 4 is a plan view of the device.

Figure 5 is a vertical longitudinal sectional view on line 5-5 of Fig. 2.

" Figure 6 is a perspective view of the Figure '8 is a perspective view showing a sheet metal blank from which the, tube may be constructed.

Figure 9 is a perspective view showing the tube formed from such blank.

In the drawing above briefly described, I have illustrated the preferred form off construction, and hereinafter, such construction will be specifically described-with the understanding at the outset however, that within the scope of the invention as claimed, latitude is allowed as to details.

The numeral 1 designates a straight; metal tube having an outwardly pressed, Elongitudinal portion 2 which imparts a substantially ovate shape in cross section to oiie end portion of said tube and rovides an? external, sharp-edged rib whic is straight from end to end. The inner extremity of this rib constitutes a rather abrupt shoulder 3 of a width corresponding to the width of the rib, this shoulder being adapted'gto engage the inner side of a can top or other wall as will be clear from the drawing. The above-described ovate end of the tube 1 is obliquely cut, preferably on a curve as shown, thus providing a point 4 and a cutting edge 5 which adapts the tube to be forced through a wall of a can, during which movement it willcut a clean opening, turn= ing the metal from the opening back, as in dicated in Figs. 1 and 2. After insertion of the tube in this manner, it .is turned so that the shoulder? will engage the inner side of the can wall, to retain the device in place.

I provide an elastic gasket -6 to contact with the outer side of the can wall, and this gasket is held in place around the tube and against the can,-by a ring '7 which may be frictionally or otherwise held around the tube 1. A pair of wings 8 are carried by the ring 7 and extendtherefrom into con- I prefer to stamp a piece of metal as shown in Fig. 7, so that the major portion of this piece forms the ring 7 while diametrically opposite portions of the metal are severed partly from the body or ring-fonning portion of the metal, by arcuate slits 9, the metal between these slits and the adjacent In forming the ring 7 and the wings 8,

edges of the piece of metal, being bent upwardly in'the same direction on a diametrical line, as will 'be clear by comparing Figs. 6 and 7. When the wings 8 are bent upwardly in the manner referred to, the distance between their uper ends, is preferably identical with the internal diameter of the ring 7, and both of these distances are a trifle less than the external diameter of the tube 1. Thus, by forcing the tube through the ring with a suitable press or the like, a tight frictional engagement is provided between the tube, and the ring and wings. This frictional engagement is suflicient to hold the parts in assembled relation, but preferably the entire device is tinned and the coating serves to further connect them.

When the tube 1 is formed from a sheet metal blank such as that disclosed in Fig. 8, the tube will have a seam on its short side, as disclosed in Fig. 9. When the ring 7 is pressed in place around the tube, this scam will be tightly closed. The entire device may then be case hardened and tinned, and the tinning operation will effectively seal the seam.

It will be seen from the foregoing that an exceptionally {simple and inexpensive de vice has been provided, yet that it will be highly eificient and desirable, and may be attached or detached with ease.

Excellent results have been obtained from the details disclosed and for this reason, such details are preferably followed. However, attention may again be directed to the fact that within the scope of the invention as claimed, modifications may be made.

I claim:

1. A device of the class described comprising a tube adapted to be forced through a can and turned for inter-locking engagement therewith, a can-engaging gasket surrounding said tube, a ring ti htly surrounding the tube to hold the gas et against the can, and a pair of wings carried by the aforesaid ring and disposed at opposite sides of the tube, said wings contacting with portions of the tube longitudinally spaced from the ring to relatively brace said tube and ring, said wings also constituting fingerpieces for turning the tube.

2. A device of the class described comprising a tube adapted to be forced through a can and turned for inter-locking engagement therewith, a canengaging gasket surrounding said tube, a flat ring tightly surrounding said tube and having diametrically opposite integral wings extending therefrom, said wings having their free ends disposed in contact with the tube to relatively brace said ring and tube.

3. A device of the class described comprising a tube having an outwardly pressed lon itudinal portion providing a substantially ovate cross-sectional shape to one end portion of the tube, the inner end of said outwardly pressed portion terminating in an external shoulder, said end portion of the tube being. obliquely cut from a point diametrically opposite said shoulder to the outer extremity of said outwardly pressed portion, providing a point and a cutting edge adapting the tube to be forced through a can wall, a flange extending outwardly from said tube in spaced relation with the aforesaid shoulder, and a can-engaging gasket surrounding the tube in engagement with said flange, said shoulder being adapted to abut the inner side of the can when the tube is turned after insertion, whereby to retain the device in place.

In testimony whereof I have hereunto afiixed my si ature. WALTER L NSFRED VVHITESIDES.
