FLASH-LIGHT SWITCH.
Specification of Letters Patent.
Patented Jan. 2, 1917.
Application filed March 14, 1916. Serial No. 84,138.
purpose to provide an ordinary flashlight with a lever or cam member of non-electric conducting material which is disposed between the spring contacts and so arranged as to positively prevent the contacts engaging with each other except when actuated and whereby the short circuiting of the battery will be effectively prevented.
With the above and other objects in view the improvement resides in theconstruction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended claims.
In the drawing: Figure 1 is a vertical longitudinal sectional view through a flashlight constructed in accordance with the present invention, Fig. 2 is a horizontal sectional view approximately on the line 2-2 of Fig. 1, and Fig. 3 is a perspective view of a cap for the flashlight. Fig. 4 is a detail vertical longitudinal sectional view through a portion of the device showing the switch member arranged between the contact members.
In the drawings, A designates the flashlight in its entirety.
The flashlight is of the ordinary construction including a metal casing 1 having one of its ends open to receive the battery B, and the said battery has a covering of insulating material. The numeral 4 designates the lamp bulb which is suitably connected with the casing 1 and which contacts with one of the poles of the battery. The bulb is further provided with a metallic or electric conducting member connecting the same with the metal casing.
The other pole of the battery at the outer end thereof has arranged thereon a spring contact member 5, and the numeral 6 designates a threaded cap which is constructed of metal and which is screwed upon the outer and open end of the casing. Arranged within this cap is a spring contact member 7 which is normally arranged to engage with the contact member 5, and the numeral 8 designates a switch lever which is eccentrlcally pivoted to the casing 6, as at 7 and which is disposed to overlie the spring con tact member 7 and to engage with the spring contact member 5. This switch lever is, of course, constructed of some suitable nonelectric conducting material and may, if desired and as shown in the drawings, be in the nature of a cam. The operating finger extends through a suitable slot in the cap, and.
the said finger, indicated for distinction by the numeral 9, may have imprinted adjacent its opposite edges suitable instructions to designate when the cam is moved to permit of the engagement of the contact members and the lighting of the lamp bulb or when the switch is moved to a wiping position or between the contact members 5 and 7.
From the above description, taken in connection with the accompanying drawings, the simplicity of the device as well as the advantages thereof will, it is thought, be perfectly apparent to those skilled in the art to which such invention appertains without further detailed description.
Having thus described the invention, what I claim is: a
An electric flashlight including a casing having a battery therein and a lamp between one of the poles of the battery and the casing, a spring contact upon the opposite end of the battery, a cap engaging the casing and surrounding the said contact, a spring contact member in the cap normally engaging with the said contact member on the end of the battery, a pivoted lever of insulating material for the cap having one of its ends projecting through an opening in the cap, the portion of the lever in the cap and beyond the pivotal connection between the said lever and cap being offset, and said ofl"- set portion adapted to ride between and separate the contact member of the battery from the contact member of the cap, when the lever is swung to one position.
In testimony whereof I affix my signature in presence of two witnesses.
