This invention relates to flash lights. 4 An object of the invention is to provide a flash light having shock resisting ends so that in case it is dro ped the lens and battery and 5 bulb will not he injured. A further object is to provide in a flash light `of this character a novel switch.
Referring to?the accompanying drawings, which are made a part hereof and on which r parts, Figure 1 isa view partly in section ofthe 'j flash light showing my f invention incor-l porated therein,

In the drawings -numeral 10 indicates a metallic-casing surrounding a fiber tube 11. The casing 10' may be made of any suitable metal such for example as brass plated with nickel to give it an attractive appearance. The inner `tube 11 may be of any suitable material but preferably of insulating material. A partition 12 of insulating material is secured in -one endof the casing 11; Secured to one side of the .partition is. a metall plate 13 having a socket for receiving an electric bulb 15 and having a bent end 14 forming one Contact for a switch. A reflector 16 may be Secured to the outer side of the plate 12, the reflector and plate 13 being held to the partition 12 as by a rivet 17.v The metal casing 10 has threads 18 and 19 formed at its ends. The rear end of the bulb has a back plate 20 which has a threaded portion. 21 to fit the threads 18 on the casing 10. A rubber cushlan View of the switch elethe back plate 20. This rubber being secured tothe plate 20 and forms a cushion for this end of the flash light. A s ring 23 may be secured on the i bear against the rear end of one of the batteries 24. Theispring 23, if desired, may be loosely positioned between the rear end of battery and the plate 20 to urge the forward p 5o battery into 'contact with the end of the bulb ion 22 is formed around and at the rear of f nner face o the plate 2.0 Itov iaso.. serial No. 442,650.:
15, the spring 23 alsovforming a ground between one end of the battery and the metal casing .10 of the flash light. A front rubber cap 25 has a reenforcing metal ring 26 embedded therein and has alens 27 secured in a groove on the inside ofthe rubber to support this lens resiliently upon the flash light ca/sing, a flange 28 on` the rubber ring extend-l ing 1n around the forward edge of the casing of the flash light.` The rubber cap is proiscrew threads thereon lfor holding the cap on the end of the flash light casing. In any case a cushionis provided by the rubber ca 2 5..wh i'ch .relieves the shock in case the llas 1 lightis dropped upon 'the floor and prevents breaking o the lens 27 or the flash light bulbi-25 or injury to eitherof theY batteries 24. j
switch for lighting the bulb comprises acas1ngS-30 secured to the metal sleeve 10 by lmeans of rivets 3 1, This casing is slotted at 32-to receive the depending end' of an operating button 33. This button is preferably of rubber or similar material. The inner end of this button is-secured Aupon 'a-contact element 34 which has one end bent at 3 5 to make conytact with the outer end 14 ofthe plate 13. The rear end 36 of the switch element is held in either rear or forward position bya hump 37 on; the casing 10. The casing 10 is Acut away at 38 to prevent contact betweenthe outer-end-14 of the element 13' and the casing 10. to prevent a short circuit around the switch. It is noted that the batteries 24 are grounded to the plate 20 so that closing acircuit through element 34 and 13 will light the bulb 15. From. the foregoing description it is thought the operation and advantages of my flash light should be clear.
This flash light particularly adapts itself for use in theaters in that the rubber button 33 will not injure the gloves worn by an usher in seating `patrons in theaters. This rubber button provides sufficient friction on the thumb to make it very easy for lthe operator to push the switch element 34 forward to light the bulb. The rubber ends 22 and 25 rovide shock absorbers in case the flash light should be dropped upon the floor. This not 2 y 1,7ss,a77
only prevents breaking any element in the lash light but also would make it less noisy.
It will be obvious to those skilled in the art that various changes may be made in my dei vice without departing from the spirit of the invention and therefore I do not limit my-` self to what is shown in the drawings and described in the specification, but only as indicated b v the appended claims.
Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:
1. A flash light comprising a tube of insulating material, a metal casing surrounding the tube, a partition in the tube, a bulb mounted in the partition, a plurality of dry cell batteries in the tube, a metal' plate secured to one end of the tube, said metal plate having a spring positioned on one side, said spring being in Contact with the rear end of one of the batteries to hold the batteries in circuit making engagement with the bulb, a rubber cushion positioned about said plate, a rubber cap screw threaded upon the front end of the easing, said cap having a lens secured therein, and a reenforcingmetallie ring embedded in the said last-named rubber cap, substantially as set forth.
2. A flash light comprising a casing, a bulb secured in said casing, a plurality of 'dry cell batteries in said casing,.a plate moun t ed on one end of said casing having a spring secured thereto adapted to contact with the rear of one of the batteries to hold the batteries in contact with the bulb, a rubber cushion positioned about said plate and a rubber cap mounted upon the front end having a metallic re-enforcing ring embedded therein, said cap having a lens secured therein, substantially as set lforth.
In witness whereof, I have hereunto set my hand at Minneapolis, Minnesota, this 28thy day of March, A. D. nineteen hundred and thirty.
