FREDERICK WESTERBECK, OF ST. LOUIS, MISSOURI.

l `SFOUTED CAN.

SPECIFICATION forming part of Letters Patent No. 761,342, dated May 31, 1904.

Application filed April 22, 1902.n

To all whom t may concern:

v Beit known that I, FREDERICK WESTER- BEGK, a citizen of the United States, residing in the city of St. Louis,k in the State of Missouri, have invented certain new and useful Improvements in Spouted Cans, of which the following is a full, clear, and exact description, reference being had to the accompanying drawingsformingI part of .this specification.

My invention relates to that class of sheetmetal cans that are provided with pouringspouts; and lit has for its object the production of a can having the spout formed integral `with the top of the can and produced from the same blank, thereby greatly lessening the cost of manufacture of the article and avoiding liability of leakage frequently occasioned byreason of imperfect and insecure connection between the spout and cantop,-wh'er e the parts are united by solder as usual. y

My invention consists in features of novelty hereinafter fully described, and pointed out in the claim.

Figure I is a View ofthe blank from -which my can-top with spout is produced. Fig. II is a perspective of the upper part of a cantop constructed according to my invention. Fig. III is a horizontal section taken on line III III, Fig. II. Fig.- IV is a cross-section of the spout, showing the edges overlapped. y

I designates the can-top, that is formed,flirst, into the blank shown in Fig. I in segmental shape, with a centralgoriice 2. Extending from the facing ends of the segmental-shaped blank are tongues 3, thatare narrowed toward their ends and occupy positions on said ends intermediate of the outer edge of the blank and the central orifice 2 and preferably nearer the orifice than the outerl edge. y

In forming the can-topfrom the blank it is bent into the conical shape shown in Fig. II and usual to-spouted cans. The body of the blank in `proximity to the tongues 3 is struck outwardly when subjected to the action of a suitable die or former, thereby producing the bulging contour of the tongues most clearly illustrated in Fig. III and forming the side Serial No. 104,225. (No model.)

walls of the can-spout. To unite` the side walls of the spout and complete it, the edges Aof the tongues are bent toward each other at t (see Figs. II and III) and overlapped and in such position are soldered together to lform a seam. The ends of the blank are also overlapped above and below the tongues and soldered to unite them, bulging the blank outwardly at the location of the tongues 3. I make the tongues of a braced form, owing to their extending from points considerably to each side at the outer end of a spout when completed, and therefore produce a spout having much greater rigid ity than can be obtained where the kspout-tongues extend directly from the body of the can-top at right angles thereto.

. When ythe can-top blank with the spout is Vformed into shape and secured, the orifice 2 furnishes the mouth of the can-top, and at this location ascrew-neck 5 is applied to the top to receive a screw-cap. A screw-nipple 6 is also preferably applied to the end of the spout to receive a screw-cap.

It will be seen that by the construction herein set forth I produce a can-top with an integral spout that has characteristic strength and rigidity and one that contains very little seam-surface, thereby lessening the liability of leakage as a result of insecure joints at the seams. Furthermore, the cost of producing the completed can is materially lessened as compared with such cans as usually manufactured by reason of the fewer operations incident to the construction of the can-top.

I claim as my invention-,-

Acan-top formed from a blank having a segmental portion bent into conical form and tongues projecting from the ends of and integral with said segmental portion; said tongues having bulged side walls and narrowing towardtheir outer ends and being overlapped y'
