SAFETY APPLIANCE FOR CONTAINERS.

To all whom it may concem Be it known that I, SAMUEL N. NORTH, a citizen of the United States, residing at Mnncie, in the county of Delaware and 6 State of Indiana, have invented certain new and useful Improvements in Safety Appliances for Containers, of which the following is a specification.

This invention relates to improvements in safety appliances for the cans or other containers for gasolene or other hydro-carbon compounds or liquids, and has for one of its objects to provide a simply constructed device which will effectually prevent blazes 16 from igniting the gases generated in the containers, and may be applied to cans or like containers of various kinds, automobile tanks, gasolene and stove tanks, reservoirs or other containers which are liable to come in direct vcontact with. flames.

Another object of the invention is to sim plify and improve the construction and increase the efiiciency and utility of devices of this character.

Another object of the invention is to provide a device of this character which may be readily applied Without structural change to cans or other containers of various sizes.

Another object of the invention is to pro 0 vide a device of this character which may be readily removed when the can is to be filled and which does not interfere with the ordinary uses of the can or other container.

With these and other objects in View,

the invention consists in certain novel features of construction as hereafter shown and described and then specifically pointed out in'the claims.

The improved device may be appliedto eans,,automobile tanks, gasolene stove tanks,

reservoirs or like containers, but is ,more particularly, ap licable to cans, and for the purpiose 'of illustration 'is shown thus 'applie and in the drawings enii loyed. to @5 illustrate the invention: v

' Figure 1 is a sectional elevation of a conventional can with the improvement applied: Fig. 2 is a plan view of the same;

preferred embodiment of the Fig. 3 is "a transverse section .011 the line 3-3 of Fig. 1; Figs. ,4 andhfare views similar to Fig. 1 illustrating.modificati ons in the construction.-

- Corresponding and like parts are referred to in the following description 'and' indi- Speeification of Letters Patent.

cated in all the views of the drawings by the same reference characters.

The can to which the improved device is applied, is represented as a whole at 10 and is provided with the usual threaded nozzle 11, the nozzleextending outwardly as shown in Fig. 1, or turned inwardly as shown in Fig. 4, and it is not desired therefore to limit the improved device to nozzles of any particular shape or form. The improved device will preferably be of the screw form, but the improved device may be permanently attached to the can as represented in Fig. 5.

The improved device comprises a guard or shell 13 of foraminous material such as perforated metal, as shown in Fig. 1, or wire cloth as shown in Fig. *i, but any suitable foramiuous material may be employed for the cage. The apertures or meshes of the cage are sniiiciently fine to prevent the pass sage of flame, but will permit liquids to freely pass.

When the improved device is applied to an outwardly directed threaded nozzle 11, as shown in Fig. 1, the cage 13 is turned over at its upper end and thence directed downwardly with the downwardly directed portion threaded as shown at 14. to engage over the threaded nozzle, and when the cage is applied to an inwardly directed nozzle as shown in Fig. 4, the upper portion of." the body of the cage is threaded as shown at 15 to engage the threads of the nozzle and with the upper terminal of the cage directed outwardly in the form of a flange 16 to bear over the upper edge of the can top. When the turned-over form is em ployed as shown in Fig. 1, a gasket 17 of cork or other like material is lnserted between the upper edge of the nozzle andthe turned-over portion of the cage, and when the form shown in Fig. 4 is employed the gasket 17 will be inserted betweenthe flange 16 and'the body of the can. By this means the joint between the cage and the can is packed" and leakage of gas at that point effectually prevented.

' When the cage 13 is permanently con nected to the can as shown in Fig. '5, of coursethe gasket 17 will not berequired. A cap device is employed over the upper open end ,of' the cage, and in the construe tion shown in Fig.1, the cap comprises a horizontal-p0rtion 18 and athreaded depending portion 19 which engages over the .i'ided "Withradii:

By this means i outlets of the can are provided with electusl safety attachments and all danger of explosions prevented.

Having thus described the invention, What is claimed as new is:

1. In a. safety appliance for containers which the container is. provided with 5 th ceded extension, a cage of forarninous riel disposed to extend within the contamer, .d cage having it threaded extendisposed parallel and in spaced relait with respect to its body portion, said wision being; received on the threaded -.sion of ti container. a cap including led portion "which is eceived on led extension of the cage, said esp rmed with an open end, :1 plate threaded extension, e cage of foraminous materiel disposed to extend Within the container. said cage being formed with e threaded extension which embraces the cage and which is received by the threaded-extension of the container, the extension of the container being; formed with en inwardly era the conical portion perforated. A

a closure for said open end and disposed flange, there being a packing disposed between said flange and the extension of the cage, a ca provided with a threaded portion received on the extension of the cage, a plate constituting a stop interposed between said ca and the cage, said plate being formed with a central aperture, the cap being provided with an opening which alines with the aperture formed in the plate, a sprin disposed within the ca said spring being formed with curved extensions which contact with the plate, a

tioned plate and said s ring.
