SPECIFICATION forming part of Letters Patent No. 476.309, dated June 7, 1892.

Application led .T anuary I2, 1892. Serial No. 417,898. (No model.)

To @ZZ whom it may concern.:

Be it known that I, GEORGE J. RECORD, of Conneaut, in the county of Ashtabula and State of Ohio, have invented certain new and .zle and cap complete.

useful Improvements in Fastenings for vthe Caps of Cans and other Vessels; and I do hereby declare that the following description of my said invention, taken in connection with the accompanying sheet of drawings, forms a full, clear, and exact specification, which will enable others skilled in the art to which itappertains to make and use the same.

This invention has general reference to improvements in fastenings for closures of vessels, especially the caps of nozzles of cans, fruit-j ars, and similar` objects; and it consists, essentially, in the novel and peculiar combination of parts and details of construction, as hereinafter lirst fully set forth and described, and then pointed out in the claim.

In the drawings already mentioned, which serve to illustrate my said invention more fully, Figure l is a sectional elevation of a can-nozzle provided with niy removable sealing-cap. Fig. 2 is a side elevation of the cap removed. Fig. 3 is a similar view of the noz- Fig. 4 is a transverse sectional elevation of a spouted closure secured to the top of the vessel by my improved fastening.

Like parts are designated by corresponding letters of reference in all the figures.

The object of this invention is the production of a metallic removable and hermeticallysealing cap for the nozzles of sirup, varnish, oil, and similar cans to take the place of the now usually-employed metallic cap which is put upon these nozzles and then burred onio the same to securely seal the nozzle, such burred caps requiring to be destroyed when it is desired to remove the same and also requiring aspecial burring-tool to apply the cap to the nozzle. This latter requirement especially is objectionable for many reasons, prominent of which is that it is a slow operation and, if improperly performed, makes the cap a useless appendage to the nozzle. To overcome these objections, I construct this fastening for the nozzle substantially as follows:

In the body A of the nozzle and in close proximity of the upper curled (immitat-ion wired) edge B of the nozzle I produceau outwardly-projecting bead C, forming in the interior of the nozzle a groove D, said body being soldered or otherwise secured to the top or body E of a varnish, sirup, oil, or other can in the usual manner.

In the cap F of the nozzle A (which cap consists of a dish-shaped body having a bottom G, an upper laterally-projecting Iiange, 6o and a downwardly-projecting rim) I produce a series of outwardly-pointing projections J, so located in relation to the groove D that when a washer K is placed into the space between the body or rim of the cap and the cap pushedinto the nozzle said projections will engage the groove D, and thereby lock the cap tightly into the nozzle, it being understood that the body of the cap fits the interior of the nozzle, (a close fit,) so that some force 7o is required to push the cap into the nozzle, which cap will snap, as it were, into position, and thereby hermetically seal the nozzle, yet be not so tightly locked but that it may be pulled out by prying it out with any suitable 7 5 instrument or simply pulling it out with the hand. It will thus be seen that but a slight effort is required to seal the :nozzle with the cap and that no instrument of any kind is needed to accomplish the object of closing the 8o same.

In some cases where a spouted faucet is used on cans and Where the empty can is shipped with the faucet detached I produce in the top of the can an upwardly (or downwardly) pointing rim A, as shown in Fig. 4:, and provide this rim with a groove D, the same as the nozzle heretofore described. I then form on the faucet a rim having projections J, analogous to those on the cap F and 9o engaging the groove in precisely the same manner as those of said cap engage the nozzle, so that when it is desired to attach the faucet to the can it needs to be pushed into the rim only to iirmlylock it in position. This construction is. an equivalent of the one described and clearly within the scope of my invention. As a reversal of the order of things,

I may mention the placing of the groove into the cap and the projections into the nozzle, zoo though this construction will interfere with the sealing of the nozzle with the usual corkstopper in addition to the sealingcap, and for this reason I do not recommend the same.

It is obvious that this device for securing the cap is applicable to nearly all covered vessels-such as fruit-jars, butter-tubs, lardpails, &c.-without change or modification.

Having thus fully described my invention, I claim as new and desire to secure to me by Letters Patent of the United States-- The combination, with the top E, of the tapering nozzle A, having the curled upper edge and an inner annular groove below the curled edge, the dish-shaped cap having the depressed bottom and the downwardly-project-
