'ro JOSEPH sATLow, or
SWITCH FOR FLASHL-LIGH'I'S.
Specification of Letters Patent. Patented Feb. 15, 1921.
Application filed April 1, 1918.'- Serial No. 225,929.-
To all whom it may concern:
Be it known that I, HARRY M. KoRE'rzKY, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Im switches of this character so as to be reliable and cilicient in use, comparatively simple and inexpensive to manufacture, and so designed that none of the parts will readily get out of order or loosen.
A more specific object of the invention is the provision of a novel combination of pushbutton and slide button so arranged that they are employed independently for closing the circuit by engagement with the contact strip within the caslng of the flashlight that lies between the switch and the metal, piece of the lamp holder.
Wit such and other objects in view, the
invention comprises various novel features of construction and arrangement of parts which will be set forth with particularity in the following description and claim appended hereto. I I In the accompan ing drawing, which illustrates certain em odimentsof the invention and wherein similar characters of reference indicate corresponding parts in all the views,
Figure 1 is a side view of a flashlight with portions shown in section to illustrate the details of construction;
Fig. 2 is a similar view showing the slide button in closed-circuit position;
Fig. 3 is a view of the switch'detached;
. Fig. 4 is a transverse sectional view on the line 4-4, Fig, 1, drawn on an enlarged scale; and
Fig. 5 isa detail view of a modification.
Referring to the drawing, 1 designates the metal casing of a flashlight having a base cap 2, a head-piece 3, and a lens 4, and containing a battery 5, a reflector 6, a lamp 7,
and a holder 8 for the lamp and battery.
The holder 8 includes a metal piece or conductor 9 which engages the metal base of the lamp and with which engages a contact strip 10 fastened in the casing and extending to the switch A. The battery is grounded on the casing and has its grounded terminal connected through the switch A, contact 10 and conductor 9, with one terminal of the lamp. The other terminal of the lam is connected by a contact 11 with the terminal 12 of the battery, the contact 11 being mounted on a metallic bridge-piece or protector 13 mounted on the holder 8 to protect the lamp from injury by the battery, details of which protector are shown in a co-pending application.
The switch A comprises a shell-like metal housing 14 which is fastened to the casing 1 by rivets 15. Within the housing 14- is arranged a leaf spring 16 fastened at one end by a rivet 17, and on the free end ofthe spring is a pushbutton 18 which projects out of the opening 19 in the housing, and under the free end of the leaf springis a switch contact 20 formed by the bending out through .an opening 21 in the casing 1, of the extremity of the contact stri 10, which latter is carried by a flexible strip of insulation 22 secured by rivets 23 to the casing 1, whereb the contact strip 10 is insulated from t e casin On the outside of the housing'is a sli e button 24 which has lugs 25 extending inwardly through longitudinal slots 26'Which have rigidly secured thereto a finger-like contact 27 which is yielding and has a sliding engagement with the projection 20 of the contact strip 10, and which slides under the free end of the spring 16. By this arrangement the circuit can be completed either by the pressing of the button 18 to engage the spring contact 16 with the contact element 20, or the circuit can be closed by moving the slide button 24 toward the pushbutton from the position shown in Fig. 1 to that shown in Fig. 2, whereby the contact finger engages the contact projection 20.
In Fig, 5 the casing 1 is shown as made of fiber insulation, and in this case the in sulating strip 22 of Fig. 1 is dispensed with and the contact strip 10*.is riveted directly to the casing 1, and the switch housing 14:
is connectedto a conductor strip 28 which lies within the casing 1 and is adapted to connect with the battery inthe usual manher. I I p From the foregoing description taken in connection with the accompanying drawing the advantages .-of the construction and method of operation will be readily understood by those skilled in the art to which the invention appertains, andvwhile I have .described the principle of operation, togethe with the device which I now consider to be the best embodimentthereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made when desired as fall within the scope of the appended claim.
Having thus described my invention, I claim as new and desire to secure by Letters Patent: 1
y In a flashlight switch, the combination of I a metallic casin a resilient support in the form of an insu ating stri fastened thereto, a contact strip carried y the insulating strip and insulated from the casing by the latter, said casing having an opening and one extremity of the contact stri projecting out of the opening, a spring xed to the casing, a push button on the spring for engagement with the projecting part of the contact strip, a slide on the casing, a finger beneath the spring, and means connecting the finger to the slide and movable along the spring to cause the finger to comeinto engagement with the projecting part of the contact strip;
