MILK-CAN.
SPECIFICATION formng'rpart of Letters Patent No. 650,967, dated June 5,1900.
' Application filed February 261900. Serial No. 6,478. (No model To (LZZ- whom t vii/ty concern:
Beit known that we, CHESTER CoMsTooK, residing at New York, (Brooklyn,) in the conntyof Kings and-State of NewYork, and JACOB B. CONOVER, residing at Metuchen, in the county of Middlesex and State of New Jersey, citizens of the United States, have invented certain new and useful Improvements in Milk-Cans, of which the following is a speci'-A cation.
- This invention relates to milk-cans, and more particularly to the construction of the neck thereof; and it has for one object'the provision of an improved can provided with a reinforced neck comprising a pair of neck portions, one integral with the breast and the other integral with the bowl, overlapping each other throughout the entire width or height thereof, one of said neck portions being provided with an integral daring lockingflange, chamfered or beveled so that its free edge will form at one side of such neck substantially a flush connection or joint with the member with which it engages, thereby to do away with the provision of a' recess formed in the metal or by bending the metal for the reception of such flange.
A further object of the invention is tofurnish a milk-can formed of a breast member provided with a rigid or integralneck and a bowl member having a rigid or integral neck, one of said necks extending withinand being overlapped by theotherneck and one of said necks having a reinforcing and locking flange extending at an angle to the plane of said neck and in engagement with an unrecessed face' of one of said members".V
In the drawings accompanying and forining part of this specification, Figure l represents the upper part of a milk-can, partially in section, showing the present improvement.l Fig. 2 is a similar view to Fig. l, showing a reversal of the construction presented in said Fig. l. Fig. 3 is a sectional View substantially similar to the part shown in section in Fig. 2, but showing the bowl and'breast disconnected; and Fig. at is an enlarged sectional view of the neck portion illustrated in Fig. 2.
Like characters denote similar parts in all the views.
For the purpose of more clearly illustrating the differences in construction between the present improvement and the prior art itY is deemed necessary to herein briefiy refer to such prior art.'
We are aware that it is not new to form the bowl, neck, breast, and a portion of the body in one piece or as an integral structure, which, however, aside from the difficulty in the manufacture of such al structure, results simply in the production of a can which must necessarily be weak at the neck portion, where it should be of great strength and rigidity, since such neck, being formed in one piece with the bowl and breast, mustbe bent at twoy points, to the injury of the fibers of the metal. Moreover, since the neck is of the same thickness as the breast and bowl it is therefore not reinforced at that point where it is subjected to rough usage in the handling of the can, it being the practice to catch the saine, especially when empty, under the flaring mouth, s0 that cans made in this manner frequently become bent at the neck thereof, such iiexure materially interfering with the proper fitting of the cover, whereby the usefulness of the can is impaired. We are also aware that it is not new to provide a bowl and abreast each with an integral neck; but in this construction no means is provided other than the tinning material for lnaintaining the bowl and breast together. We are also aware that it is not new to provide the bowl Vwith an integral neck and the breast with an integral neck overlapping the bowlneck vand having a part adapted to overlap the breast and thereby provide not only a reinforced neck, but a reinforced breast. We are also aware that it is old to provide a bowl and a breast formed independently of each other and connected together by a pair of necks formed independently of such bowl and'breast and each provided with flaring flanges overlapping the bowl and the breast. In this construction, however, the neck-s are not formed integral with the bowl and breast, but are separate therefrom, whilethe edges of the Haring flanges form a plurality of relatively-large joints, which easily become impregnated with foul milk and germs. XVe are also aware that it is old to provide the bowl with an integral neck and the breast IOO with an integral neck and a flaring lockingtiange, the bowl or breast being recessed adjacent to itsjuncture with its neck for the reception of said lockingflange, thereby to form a flush joint. In this construction a flush joint is provided to prevent the fouling ofthe eau; but to provide such flush joint it is necessary that. an annular recess be formed inthe bowl or breast or that such bowl or breast, as the case may be, be bent to form said recess. In eithereventthe formation of this recess tends to weaken the can, since if the recess be formed in the metal some of the metal must necessarily be removed, while if the metal be bent such flexure strains the fibers of the metal, so that weakness results at a point where the can should be of considerable strength and where it has already beenv beut-namely,at the j unct ure of the bowl and the neck or of the breast with the neck, as the case may be-so that in such construction by reinforcing the neck one part of the neck is robbed of its strength and resisting qualities,
lo reinforce another part thereof.
'lhe above is, so far as we are aware, the only construction in which a flush joint is provided, and as it is a well-known fact that a few drops of foul milk will when brought into contact with pure milk during even a short. railroad journey foul the entire contents, consisting of many gallons, it will be readily `seen that the provision of a flange the edge of which is not substantially .flush with the part with which it engages merely leaves a joint of considerable size to constitute a means of retaining foul particles of milk, so that it is absolutely necessary if a flange be provided for locking the bowl and breast together and which is essential to a rigid and durable structure that such Hange shall constitute a flush joint to all intents and pu rposcs with the part with which it engages; and to do this without weakening the metal adjacent to the juncture of the neck by the bending thereof or the formation of a recess therein, while at the same time to provide an organization in which the bowl will have an integral neck and the breast an integral neck, each formed independentlyof the other,there by facilitating the manufacture of the product an d form ing when assembled a reinforced duplex neck, is the object of the present invention.
To this end the improvement comprises in a general way a bowl having a rigid or integral neck and a breast having a rigid orintegral neck, each formed separately from the other and one of said necks having a flaring locking-flange beveled or chamfered toward its free edge and adapted to engage the bowl or the breast, as the case may be, and form therewith at such free edge substantially a flush joint.
In the form thereof herein shown and described the improvement comprises a bowl 2, the upper edge 3 of which may be reinforced in any desired manner and havingvan integral depending neck extending at an angle to such bowl, a breast 5,which may be united to the body in any desired manner, having an upwardly-projecting neck 6 extending at an angle to such breast, the neck of one member adapted to overlap the neck of the other member throughout the entire width or height of such necks. One of these necks-as, for instance, the neck of the breast (see Fig. 2)-is provided with a flaringloeking-flange 7,which is beveled or chamfered toward its free edge, so that such edge may be brought into very close engagement with the inner face of the bowl, whereby a flush joint is provided for all practicable purposes, the construction beingsuch that the bowl hasa relatively smooth and unbroken inner face from the juncture of the locking-Harige with its neck to the u pper edge of such bowl.
In another form thereof (shown in Fig. l) the construction shown in Fig. 2 is reversed, the neck 4 of the bowl 2 having the flaring locking-flange 7', constructed in the manner above specified, whereby it will form with the inner face of the breast substantially a flush joint.
By turning the locking-flange 7 or 7/ outwardlyata relatively-sharp angle to its neck itis effective to lock the parts firmly together, and by providing such flange with a beveled or chamfered edge the upper surface 7" ot' such flange merges into the inner surface S of the bowl or breast, as the case may be, withont the formation of any appreciablejoint.
,lly the provision of a can having the construction set forth ity will be seen that the bowl and the breast may be form ed separately from each other,which is an essential feature in the manufacture of milk-cans, while at the same time a reinforced neck is provided consisting of two parts of the samev width or height, each of substantially the same-thickness as the metal of the bowl or breast and out the necessity of bending the metal of the bowl or breast to form a recess,thereby straining the fibers of the metal, or to remove a portion of such metal to form such recess.
Vhen the parts have been assembled and firmly located together, they are subjected to the usual tinniug operation, whereby the seams are filled and the parts firmly united by the tinningmaterial,which acts as a soldering medium. In practice this tinning material will constitute abridge between the practically inappreciable edge of the 'beveled flange and the face of the bowl, thereby positively preventing the formation of any appreciable joint for the retention of foul particles of milk or germs.
From the foregoing it will be seen that in the present improvement a can is secured which from a sanitary point of view is equal in every way to a can made without joints,
