`Specification of Letters Patent.

Patented March 23, 1909.

v Application led December 7, 1908. Serial No. 466,325.

To all 'whom it may concern:

Be it known that I, RICHARD BRAY, a citizen of the United States, residing at Arlingf ton Heights, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Milk-Cans, of which the following is a speciiication, reference being had to the accompanying drawings.

This invention relates to ,milk cans and particularly to improvements in the construction of the necks thereof.

Cans used in the shipping of milk are ordinarily subjected to roughusage and many expedients have been employed to strengthen them in various parts to better withstand such usage. The necks of such cans are recognized as being among the places that require extra strengthening and elforts have been made to protect such parts, but, so far as I am aware, such efforts have been confined to protecting only the lower or cylindrical portion thereof either by the use of a protective band or by making said lower portions of the neck of more than a single thickness. It is found in practice that the entire neck portion of a can-that is the flaring upper portion as well as said lower cylindrical end-must beequally strong to secure satisfactory results, for even if the lower cylindrical part be maintained in perfect form or shape, a denting or battering of the said upper flaring portion will prevent that accurate fit of the cover in the neck that is essential to a perfect closing of the canin order to maintain the contents thereofin a sanitary condition.

It is the object of my invention to provide an improved construction whereby the'entire neck portion of `a milk can will be given great strength at all points and hence will be able to resist all ordinary blows tending to distort it.

A further object of my invention is to provide an improved connection or joint between it and the breast of the can.

In the drawings-Figure l is a side elevation of a milk can with my improved neck portion applied thereto; Fig. 2 is an enarged detail, being a vertical section through a portion of my improved neck, showing the formation of the inner member of the neck before the neck is secured to the breast; and Fig. 3 is a view similar to Fig. 2 but showing the manner of connecting the neck and breast together-a portion of a can breast being also shown.

Referring to the several figurea-A represents a milk-can body, B the breast thereof and O the neck of the can.

The neck O is formed of two members, an inner andan outer one, indicated, respectively, by a and b, each formed of a single piece of sheet-metal and preferably seamless. Each member can be drawn into the required shape by suitable dies, the closed end of the cylinder produced in the drawing o eration being, of course, cut out as usual. T e member a iits closely within and against the member l), as shown, each part being drawn so that the neck as a whole has the. usual upper flaring portion and the lower cylindrical portion.

In the formation of the neck O the upper edge of the inner member a, will extend beyond the upper edge of the other member so as-to permit the formation of a roll edge o that will inclose the outwardly-turned edge c of the outer member b, and the lower edge of the outer member will extend below the lower edge of the inner member so as to permit the forming ofv an outwardly-turned flange d that will, when the neck is secured in place to a breast, lie against the outer face of said breast. By turning the upper edges of the members a and b as described, so that the edge of the outer member is inclosed by the rolled edge of the inner member, the two members are securely locked together. The inner member a at its lower ortion projects below the line along whici the outer member is turned to form the ilange d, as clearly shown in Fig. 2, such projecting portion being adapted to form an outwardlyturned flange f that will lie against the inner face of the 'breast B, as clearly shown in Fig. 3.

A completed neck is illustrated in Fig. 2,

' and its manner of attachment to the breast of a can is seen in Fig. 3, the ilanges d and f lying against the outer and inner faces, respectively, of the breast, as already described, where they will be secured by solder applied along the edge of the iiange d. I do not deem it necessary to solder the flange f to the breast because for plurposes of strength the soldering of the ot er flange d to the breast will be suflicient, and for the purpose of ii'lling up the crack between the lower edge of the flange f and the innersurface of the breast the tin deposited during the usualtinning bath will be found sufficient to prevent the lodgment ot particles of milk. As it is highly advisable to have as nearly a perfectly smooth interior surface in milk cans as possible, I make provision for avoiding the ridge that would occur if the 'flange f rested on the inner face of the breast so as to be raised above that portion of such sur.- face below the flange. l avoid having such ridgeby making. a small bend, as at g. (Fig. 3), around the breast B a short distance from itszdge, thus raising theedge. portion of the breast, and it is` against this raised portion that the flange]r rests, the edge of the flange terminating at the saidbend. This construction provides for a smooth interior surface at the joint between the said flange f and the breast. The smallv crack left will be, as stated, filled up by the molten. tin` during the tinning-bath to which4 theentire neck is subj ected. Theouter flanged is, asv shown, also slightly bent to conform to the bend at g in the breast, and fitting snugly, as it does, over such bend aids in more securely locking the neck and breast together.

Ln, addition to the great strength produced by my construction, the entire interior of the neck is of, course perfectly smooth as there is nojoint at any point fromthe upper to the loweredge, which enables this portion of the can to be easily cleaned and 1naintained at all times in ay sanitary` condition.

That which l claim asA my invention, and desireto secure by Letters Patent, is,-

l'. A milk-can neck, comprising al flaring upper portion and a, cylindricalA lower portion, said neck being formed ol' two walls lying in contact with each other and,- connected together along the upper edge ci' said flaring portion, and adaptedl to. beeonnected along` t ie lower edge of saidl oylindrical.l portion to` av can breast.

2. A milkfcan neck, comprising a flaring upper portion and a cylindrical lower por.- tion, said neck being formed of, two. walls lying in contact with each other and connected together along the upper edge of the saidl flaring portion and separated` at the lower edge of,` said cylindrical portion to adapt them to receive between them the upper edge of a` can breast.

3. A milk-can neck, comprising a flaring upper portion and a cylindrical lower portion, said neck being formed ol' two walls lying in contact with each other, the upper edges of said walls being curved outward,-the edge portion of the inner wall being curved around and inclosing the curved edge portion of the outer wall, and said cylindrical portion of the neck being adapted to be secured along its lower edge to the upper portion of a can breast.

ln a milk-can, a neck comprising a. flaring upper portion and a cylindrical poi:- tion, said neckI being formed ofl two walls lyingy in contact with each other and connected together along the upper edge of said flaring portion and separated at the lower edge of said cylindrical portion and bent to l'orm two outwardly-directed., flanges, in combination with a can-.breast having its upper edge extending between saidi flanges, said can-breast being bent a short distance from its edge to provide a raised portion against the inner Vfalce of.' which the innerl one of said two flanges rests, substantially as and for the purpose specified.

In a milk-can, a neck comprising a flaring upper portion and a cylindrical portion, said neck being` formed oll two walls lying in contact with each other and connected together along the upper edge of said flaring portion and separated at the lower edge` ol' said eyliiulriea portion and bent to forni two ouinwardly-directed flanges,` in combination with a can-breast liaving its upper edge extending between said flanges, said can-breast being bent a short distance l'ronr its edge to provide a raised portion against the inner face of which the inner one of said. two flanges rests, and the outer one of' said flanges being bent to correspond to the bending in said breast, substantially as and for the purpose specified.
