COVER-FASTENING FOR JARS, 84.0.

SPECIFICATION forming part of Letters Patent No. 417,540, dated December 17,1889.

Application filed April 29, 1889.

To all whom it may concern.-

' Be it known that I, JAMES CAMPBELL, a citizen of the United States, residing at the city of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Oover-Fastenings for Jars, &c., of which the following is a specification, suflicient to enable others skilled in the art to which the invention appertains to make and use the same.

My invention relates to fastenings for the covers of the glass jars employed in the transportation and delivery of milk to daily customers; and it consists in the construction and arrangement of parts, hereinafter described and claimed specifically, whereby a simple cover and fastening device is attained that is convenient and effective in use, and cheap of construction.

Owing to the large percentage of loss and breakage of the glass jars in use, for which the milk-dealer has to suffer, economy in the first cost of the jars is an item of importance, and it will readily be seen that the simplicity of my device admits of its application to the jar at a minimum cost, while it is none the less effective in operation.

My device is especially designed and adapted for application to the ordinary glass milkjar found in the market, the form of the neck of which is shown in the drawings, one object of my invention being to avoid the necessity of using a jar of special form and manufacture. For instance, I avoid the necessity of a specially-formed shoulder on the neck of the jar for holding the connectingband away from the shoulder upon the neck with which the fastening-bail is usually made to engage, by making in my device an enlargement or spacing-block directly upon the connecting-band, which spacing-block by engaging with the under side of the said annular shoulder holds the connectin g-band'asufficient distance below said shoulder to permit the horizontal bar of the bail to be freely sprung on or off the annular shoulder.

Another feature of my construction con sists in forming the connecting-band and upright loop to which the cover is attached of a single piece of wire, the ends of which are brought together under the annular shoulder Serial No. 308,915. (No model.)

of the jar, and connected by the spacingmetal having an extension or tongue, which,

is bent over and around the upright hingeloop of the connecting-band, said cover-plate having attached to it centrally a swinging bail made of a single piece of wire, the ends of which are inclosed and held by a cap extending centrally across the cover-plate.

In the accompanying drawings, Figure 1 is a' top View of a milk-jar provided with my improved form of cover and fastening. Fig. 2 is a side elevation of the neck of the jar with the cover loosened; Fig. 3, a similar view at right angles to Fig. 2, showing the cover fastened down; Fig. 4,-a view similar to Fig. 2, showing the cover fastened down; Fig. 5, a similar view showing the hinging of the cover. Fig. 6 is a central vertical section, upon an enlarged scale, through the neck of the jar provided with my improved cover and fastening.

The glass jar A is of the usual construction found in the market, no especial form or manufacture being requisite. The necks a of these common jars are formed withthickened side walls and the ordinary exterior annular shoulder a.

The cover B consists of a simple disk of sheet metal formed with a radial tongue or extension I) at one side, which is bent around the horizontal top of the hinge-loop c,'which forms a part of the connecting-band O, and is then brought back to the top of the cover B, thus constituting a simple but effective form of hinge. The under side of the cover is adapted to fit upon and over the edges a of the mouth of the jar in the usual manner.

The connecting-band C and the upright hinge-loop c are formed of a single piece of wire bent around the neck of the jar and twisted into the said loop 0, the ends of the wire being brought together and secured by the spacing-block c, which latter is designed to be formed of solder or some other similar substance adapted to have the ends of the IOG wire embedded in it, and to be shaped to fit under the annular shoulder a of the jar. The size or thickness of the spacing-block c is made sufficient to hold the band C (which is bound by it tightly around the neck of the jar) below and away from, but substantially parallel to, the annular shoulder a, thus creating a space or recess (0 Fig. 6) between the connecting-band C and said annular shoulder a, into which the horizontal bar (Z of the bail D may be pressed to secure the coverB against the edges a of the mouth of the jar.

The bail D is formed of a single piece of wire, the central portion of which forms the horizontal bar 01, the side arms d d being bent upward therefrom and then inward toward each other, and the horizontal ends thus formed being secured to the central portion of the cover B by the transverse cap b.

\Vhere the bail D is formed of wire of a suificient degree of elasticity to admit of the bar d being readily sprung on or off the annular shoulder a, the loops (1 (1 may be dispensed with; but under ordinary circumstances I prefer to form the bail with such loops (1 (Z as they not only increase the clasticity of the bail, but also afford a convenient bearing for the fingers while fastening or unfastening the cover.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In combination with an ordinary glass milk-jar A, formed with the usual exterior annular shoulder a, the connecting-band O, and hinge-loop 0, formed of a single piecebf wire the ends of which are secured by the spacingblock a, the cover B, hinged thereto, and the locking-bail D, the Whole arranged and operating substantially in the manner and for the purpose set forth.

2. In combination with an ordinary glass milk-jar formed with the usual exterior annular shoulder a, the locking-bail D, cover B, and loop 0, which unites the cover and the connecting-band C, the latter being formed with a spacing-block c, for the purpose of holding said connecting-band C from contact with said annular shoulder a, substantially in the manner and for the purpose described.

.3. The combination, with an ordinary glass milk-jar formed with the usual exterior annular shoulder a, the connecting-band O, and hinge-loop 0, formed of asingle piece of wire, the sheet-metal cover B, formed with the tongue or projection 11, which is bent around the top of the hinge-loop c, and the lockingbail D, formed of a single piece of wire, the ends of which are-secured centrally to the cover B by the cap I), the whole arranged and operating substantially in the manner and for the purpose described.
