Application February 6, 1937, Serial No. 124,454

1 Claim.

This invention relates to certain new and useful improvements in an emergency light and container therefor, and is particularly adapted for construction work or for railroads and embodies a light and its container that can be quickly made available and one which can be produced at a comparatively small cost.

A still further object of the invention is the provision of an emergency light having a carbide casing and a container in which the carbide casing is inserted, and means to retain the latter in fixed resilient position within the container.

A still further object of this invention is the provision of an emergency light, efiicient'in operation and one that can be quickly assembled and made ready for use at all times.

A still further object of this invention is the provision of an emergency light and container therefor, which container is adapted to be filled with water and toretain the casing of the light proper in fixed position therein, and ready for use in any emergency in construction or railroad work.

With these and other objects in view, the invention consists in certain novel features, combination and arrangement of parts as will be hereinafter more fully described, pointed out in the accompanying drawing, and claimed.

In the drawing,

Figure 1 is a vertical, longitudinal, sectional view of the casing and container, with the container partly broken away, illustrating the device as made in accordance with this invention;

Figure 2 is a perspective View of the container and casing in fully assembled position;

Figure 3 is a transverse sectional view, taken on the line 3-3 of Figure 1; and,

Figure 4 is an enlarged, fragmentary, sectional view, taken on the line 4-4 of Figure 3.

Referring to the drawing, the numeral 5 indicates a casing in the form of a cylindrical shell having a bottom portion 8 and top portion 1, all soldered or welded together to form an air and water tight casing, as clearly illustrated in Figure 1. ihe bottom 6 of the casing 5 is provided with an opening 3, through which opening water is admitted into the casing, the purpose of which will be hereinafter more fully described. The top of the casing 5 is provided centrally with openings it, which coincide with the opening 8 for the purpose of permitting gas generated in the casing 5 to escape therethrough to the atmosremovable tab I I sealed thereto to normally close the opening against air and water until ripped therefrom by virtue of the handle portion 52.

The openings H1 in the top 7 are normally closed in an air and water tight condition by a cap I3 provided with a handle M to permit the cap to be readily removed therefrom, the purpose of which will be hereinafter more fully described.

A supporting tube l5 has its lower open end secured around the opening 8 in the bottom i of the casing and projects upwardly in a vertical position within the casing 5. Its upper closed end It is provided with openings ll which establish a communication between the exterior of casing and interior thereof by virtue of th opening 8 and openings 17, the purpose of which will be hereinafter more fully described.

A perforated tube I8 is secured by one end to the interior of the bottom 6 of the casing 55 and completely surrounds the member it, extends upwardly and vertically through the casing 5 and has its upper end secured to the interior of the top 1 surrounding the openings ill therein. ihe purpose of this tube is to protect and prevent the openings l1 and 8 from becoming clogged or choked up by the mushy detritus of the spent carbide, as will be hereinafter more fully described.

Surrounding the tube IB, near its central portion, is an annular disc l9, and it is secured to said tube in such a manner as to separate the casing 5 into a gas chamber 2i! and a carbide chamber 25, and the latter chamber has placed therein suitable carbide A.

The diameter of the disc I9 is such as to permit gases formed in the carbide chamber to pass between its peripheral edge and the interior wall of the casing and to pass up into the chamber It is also to be understood that gases generating in the carbide chamber will pass up through the tube [8 into the chamber 23 and through the openings 1 i! of the top I.

When it is desired to use the structure de-- scribed, it is only necessary to place the casing in a container of water. Prior to placing the same therein, the tab H and cap l3 are ripped from their respective covers by virtue of handles l2 and I4 thereof. Water entering through opening 8 is forced upwardly through openings ll, out through the perforations of the tube l8 into the carbide A, gas generating therein passes up through the tube and around the peripheral edge of the bafile l9 into the chan ber 20, and when suflicient gases are generated in chamber 2i! they pass back through tube out the openings l where they are ignited at that point.

Now, to provide a container for this emergency light I have provided an open end receptacle 22 having its bottom fully closed, as at 23, and its open end provided with an entrance opening 24 of a diameter slightly larger than the casing 5. The inturned flange 24, constituting the entrance opening of the open end of the receptacle 22, definitely positions the casing centrally within the receptacle 22.

To normally center and retain the casing 5 in fixed position within the receptacle 22, I have secured in said receptacle on its side and'bottom walls, resilient supporting elements 25, which are secured to the bottom and side walls of the receptacle 22, as at 26, by any fastening elements suitable for the purpose.

The resilient supporting elements 25 firmly hold the casing 5 in fixed relation about the central axis of the receptacle 22 and also hold the casing 5 in proper position with relation to the open end thereof, as can be clearly seen in Figure 1 of the drawing. The receptacle is also provided exteriorly with a suitable handle 21, which renders the same portable and permits it to be easily transported from place to place and put in proper position when it is desired to use the same.

And to retain and lock the casing 5 in the receptacle 22, there is provided a turn catch 28, pivoted as at 29, to the top of the receptacle 22, one end constituting a handle and its free end constituting a retaining member to hold the casing 5 against vertical movement within the receptacle 22.

The receptacle 22 is to be approximately filled with Water and the casing 5 fastened therein. When it is desired to use the emergency light it is only necessary to turn the catch 28, lift the casing from the receptacle 22, rip the tab H and cap I 3 therefrom, reinsert the casing in the receptacle 22, which submerges it in the water contained therein, refasten the catch 28 and ignite the generated gases emanating from the openings l 0 of the casing.

The action of this emergency light in operation is practically identical with the structures claimed in co-pending applications Serial Nos. 124,451 (now Patent No. 2,120,523), 124,452 and 124,453, executed and filed of even date herewith, the only exception being the container and the construction of the tube l8.

While I have described one embodiment of the invention, it is to be understood that various changes might be made in the construction, combination and arrangement of parts, without departing from the spirit of the invention as claimed.

Having thus described my invention, what I claim as new is:

A portable emergency light and water container therefor, comprising a carbide casing having a water entrance and gas exit therein, removable closures for the entrance and exit, a perforated supporting tube secured to the entrance and extending upwardly in the casing, a perforated conveying tube secured to and about the first named tube and having its free ends secured to and about the entrance and exit openings, and a portable water container provided with interior flexible means to receive and retain said carbide casing in vertical position in said container so that the device may be held against displacement in transit.
