HOMER WRIGHT, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR or TWO- THIRDS OF HIS RIGHT To HENRY n. COLLINS AND BENJAMIN r. con
LINS, OF SAME PLACE.
IMPROVEMENT m JUG-TOPS.
Specification forming part of Letters Patent N 0. 129,303, dated July 16, 1872.
I, Home WRIGHT, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented anew and useful Improvement in J ug-Tops, of which the following is a specification:
My invention relates to a jug-top, constructed so as to return the drippings or overflow to the jug; and consists in the use of a sheetmetal inner lip, in combination with a cast body and neck, economy of metal and facility of manufacture being the prime objects.
In the accompanying drawing, Figure 1 is a perspective View of my sheet-metal lip. Fig. 2 is a side elevation of a jug-top, showing the sheet-metal lip in place. Fig. 3 is a vertical section through the middle of the lip, body, neck, and lip.
To enable those skilled in the art to make and use my invention, I will proceed to describe it.
With a proper die I cut my lip A from thin sheet metal and form it into the general halfcircular shape shown in Fig. 1, with its lower edge at B grooved or perforated for the purpose of giving it a firmer hold in the cast alloy. I provide also a metallic mold, with cores properly shaped, and within which is provided a recess or carp for the purpose of receiving and retaining the lip A in proper'position Within the mold. In the production of a jug-top I first introduce the lip A into the recess or carp in the mold, permitting the grooved or perforated edge B to project within, and having prepared a quantity of melted alloy, (Britannia, for example,) I pour this into the mold, and thus form body 0 and neck D, when it immediately unites with or embraces the grooved edge of lip A and forms a permanent joint. It is now ready for the reception of the lid E, when it is turned and finished in the ordinary manner.
It will thus be seen that I can produce a jug-top so constructed as to return the drippings or overflow to the jug, having an inner lip of thin sheet metal, which does not require to be over one-half the thickness of cast metal, (the latter will not flow in the mold at a less effecting a saving of one and three-quarter pounds of metal per gross, which is no inconsiderable item in view of the fact that several thousand gross of jug-tops are annually made at the factory with which I am connected.
I prefer Britannia sheet metal for the lip, as it united more readily with the cast metal, while it takes a high polish from the rolls and requires no further finish. In case a sheet metal is used that will not unite with the cast alloy--sheet-tin, for example-I find that the groove or perforations B afford suflicient hold for the cast metal.
A skillful workman with the aid of the blowpipe may be able to solder an inner lip to a jug-top body, but it would be a tedious and expensive process; while in the abovedescribed mode any one capable of placing the lip within the mold and handling an ounce of metal alloy may-produce the body and neck, and attach the lip by the simple act of pouring the metal into the mold.
I am aware that metals of different kinds have been united by casting one upon the other; and that articles denominated pitcher-tops have been made of several pieces, and soldered together or cast solid; but they lack the distinguishing features of a jug-top, to which alone I seek to apply my improvement,
Which is an article of a distinctive form, having a ewer mouth, and is a well-known article of manufacture; and I am not aware that it has ever been provided with an inner sheet-metallip, attached as described above, previous to my invention.
Having thus described my improvement,
what I claim as my invention is- A jug-top having an inner sheet-metal lip, in combination with a cast body and neck, the body and neck being cast upon the lip substantially in the manner described.
