FLASH LIGHT.

Application filed August 5, 1925.

My invention relates to Hash-lights, and it is a distinct and practical improvement to overcome certain practical objections to, and defects in, Hash-lights of the present construction.

The object of my invention is to provide a flash-light with a tin foil, or equivalent, covering for the casing thereof to act as a conductor of electrical current.

A further object of my invention is to provide a flash-light with a tin foil, or equivalent, covering for the casing thereof to act as a conductor of electrical current and with depressible circuit controlling means for making and breaking` the electric circuit.

A further object of the invention is to provide a Hash-light having` an electric circuit partly within a container and partly upon the outside of the container and yieldable controlling means for said circuit.

A further object of the invention is to pro-v vide a circuit closing means in contact at one end with a lengthwise conductor of electrical current and having a yieldable portion provided at one end with an extension to be depressed by the screw threaded sleeve holding` the reflector and lens in position and held in such depressed position for engagement with the metallic reflector carrying an electric lamp for affording a permanent light.

A further obj ect of the invention is to 3rovide a flash-light container of fiber stoc to which is fixed a circuit closing element that can be moved into contact with the reflector for closing a circuit by depressing one end of the circuit closing member.

A further obj ect of the invention is to provide a fiash-light having an outer conductor, an inner yieldable conductor connecting at its inner end with the outer conductor and at its outer end with the reflector, means for holding the outer end of the inner conductor in or out of contact with the reflector, yieldable circuit closing means and means for holding the circuit closing means in a closed position to afl'ord a permanent light when a flash light is not desired.

A still further obj ect of the invention is to provide a flash-light having an outer conductor in the form of a tin foil covering for the casing and in contact at one end with the reiiector and yieldable circuit closing` means at the opposite end of the Hash-light and means for holding the circuit closing means in a closed position when a steady light is desired.

Serial No. 48,208.

A still further object of the invention is to provide a flash-light, an inner conductor yieldable at one end for contact with a reflector and fixed at its opposite end for contact with a metallic closure for said latter end of the flash-light.

A still further objectof the invention is to provide a flash-light which possesses advantages in points of simplicity and efficiency, and, at the same time proves itself comparatively inexpensive in cost of manufacture.

With the above and other objects in view, the invention consists in the novel features of construction, arrangement and combination of parts hereinafter more fully described and finally pointed out in the claims hereto appended.

Referring to the accompanying drawings forming a part of this specification, wherein like characters of reference denote similar parts throughout the several views:

Fig. 7, is a view partly in side elevation and partly in sectional elevation of a further modified form of Hash-light, with the circuit controlling means in open position.

Fig. 8, `is a detail of one end thereof showing the circuitcontrolling means in closed position.

In the drawings, the reference character l represents a tubular container which is made from suitable ber material and which is of any size., such as length, diameter and thickness of wall. The reference numeral 2 represents a pair of suitable batteries; 3, the lens; Ll, the metallic reflector; 5, the electric lamp bulb for said reflector; and, 6, the electrical connection between the batteries and the lamp. The batteries, lens, lamp bulb, reflector and electrical connection 6 are of the usual character, as is manifest.

The forward end of the tubular container 1 is provided with a fixed metallic screw threaded sleeve 7 having the inturned forward edge 3 engaging the end face 9 of the container. Mounted upon the inturned edge 8 of the sleeve 7 is the customary reflector 4 which has an outwardly flanged forward edge 10 to seat upon the inturned edge 3 of the sleeve 7. The'lens 3 is seated upon the reflector flange 10 and the lens 3 and the reflector 4 are both secured against displacement by means of a metallic screw threaded retaining ring 11 engaging the sleeve 7, which ring 11 is provided with the inturned edge 12 for engaging the lens 3.

The container 1 is provided at its rear end with a fixed metallic screw threaded sleeve 13 having the inturned rearward edge 14 engaging the end face 15 of the container 1.

The numeral 16 designates a suitable outer conductor. The outer conductor 16 acts as a covering for the container 1 and itis inl the form of a sheet of tin foil applied to the outer face of the container 1. The sleeves 7 and 13 engage the tin foil conductor covering 16 as clearly shown in FiO'. 1, and are crimped to the container, as at 17, as shown in Fig. 2.

The circuit controlling means comprises a suitable disk 18 of non-conducting material limited as to outward displacement by means of an inturned flange 19 at the rear edge of a screw threaded retaining ring 2O mounted upon the sleeve 13. A suitable conductor 21 in the form of a fiat metallic strip, is fixed to the inside face of the disk 18 at the center thereof by means of a suitable rivet 22. The conductor strip 21 extends radially to the peripheral edge of the disk 18, as shown in llig. 4. A coiled spring conductor 23 is lconnected at its outer end to the rivet 22 and the forward end thereof is in contact with the rear end face of the rear battery 2. The coiled conductor 23 serves the dual function'of holding the batteries in contact with each other and the front battery in contact with the lamp connection 6 and also for holding the conductor strip 21 out of contact with the inturned flange 14 of the conductor sleeve 13 when the ring 20 is slightly backed ofl` on the sleeve 13, as shown in Fig. 1.

It will be here observed that when the circuit controlling disk 13 is forced inwardly by means of the lingers of the operator that the conductor 21 is moved into contact with the flange 14 of the sleeve 13, thereby closingv coiled spring conductor 23, thereby opening the circuit.

Now, if it is desired to establish and burn a steady light, the operator turns the ring 2O inwardly upon the sleeve 13 which moves the conductor 21 into contact with the flange 14 of sleeve 13 for closing the electric circuit, as is manifest, and which is clearly shown in Fig. 3.

In the modified form of device shown in Figs. 5 and 5, it will be observed that I elimi nate the ring 20, the disk 18 and the conditietor strip 21 and substitute therefor the screw threaded cap 24; also, l eliminate the rivet 22 due to the fact that the base of the coiled conductor 23 is enlarged to bind against the side wall of the vcap l further eliminate the flange 3 of the screw threaded sleeve 7 so as to cause the flange 16 of the reflector 4 to engage the end face 9 of the non-conducting container 1.

The circuit controlling means in the modified form of invention, instead of being in the form of a yieldable disk and conductor strip 21 in cont-act with the coiled conductor 23, I employ a flat conductor 25 in' the form of a flat metallic strip which is fixed to the inner face of the container 1 near the forward end thereof by means of a rivet 26. The rivet 26 passes through the wall of the container' 1 and engages the tin foil covering 16 and thereby also acts as a conductor between the conductor 25 and the tin foil conductor 16. The forward end of the conductor 25 is bent upwardly, as at 27 and then back upon itself, asat 23. This folded end of the conductor 25 passes Athrough an opening 29 in the wall of the container 1 and a registering opening 30 in the sleeve 7 with the outer end thereof' exposed to be depressed by the linger of the operator to bring the inner end thereof into Contact with the reflector when it is desired to close the circuit when opera-ted as a flash-light.

Vhen it is desired to establish. and burn a steady light, the yretaining ring 1l is moved inward upon the sleeve 7 causing the inner edge thereof to engage and depress the folded end of the conductor 25 for firmly holding it in contact with the reflector 4.

The modification shown in Figs. 7'and 8, it will be seen are the same as shown in Figs. 5 and 6, with the exception that l eliminate the tin foil conductor 16 which also acts as a cove ering for Vthe non-conducting container 1, and, the conductor strip 25 in this modification is provided with a rearwardly directed extension 31 which has its rear end hook shaped, as at 32, and held between the sleeve 13 and the end face 15 ofthe container 1.

The many advantages of the herein delimited myself to the exact details of construction shown and described, but desire to have it understood that the invention I have shown in the drawings is merely illustrative, as it is manifest that various minor changes may be made in the exact construction and particular arrangement of parts without departing freni the spirit of my invention, hence I reserve the right to make any suoli changes, or modifications as may fairly fall within the scope of the appended claims when fairly construed.
