The audible vsignal means 12, flash light means 14 and batteries l15 provide advantageously an additional Weight to the casing 10, to render the same more effective when it is being used as a club, as will be readily understood.
Referring to Figs. 1 and 2,'the audible signal means 12comprises a diaphragm 17 disposed across the interior of the casing 10, said diaphragm being adapted to vibrate Vso asto constituteywith the casing end 11, a horn. The diaphragm 17 is preferably of .magnetic material, by which it is attracted by a magnet coil 18 having a core 19 extending in close proxiniity to theinner face of the diaphragm. Y t
As shown in Fig. 1, vthe magnet coil 18 may be mounted in a metal cup 20, which when formed of magnetic material will constitute in large measure a return magnetic circuit for the coil 18. The cup 20 is shown as fitting normally within the casing 10, and in the event-thatthe casing "should alsobe constituted of magneticvmaterial it would further actas a part of a return magnetic circuit for the magnet. j,
The end 11 of the'casing 10 has a perforated grill plate or disc 22 which is securedfinasleeve 23 snugly tted in the casing 10 and at its inner end Yhaving an inturned flange for positioning an annular insulating ri'ng 25 in which the diaphragm 17 is carried. An externally threaded ring 26 secures `the insulating ring 25 in place, against the internal flange of-the sleeve 23.
Attached to the diaphragm 17 is a breaker arm 28 to which one end 29 of the coil 1'8 isV attached, said breaker arm extending through an opening 30 inthe cup 20 and being engageablewith alcontact 31 carriedby a. stepped contact cup 32 mounted within anl insulated sleeve 33 snugly Vfitted in thecasing 10. l
Attraction of the diaphragm 17 by the core `19 will eiect a flexing `of the diaphragm and a'separation of the breaker arm 28 from thercontact 31,` and suchl action is utilized to continually interrupt the circuit throughthe Vmagnet coil 18. in the well-known mannerV of a buzzer,
to eifect continuous vibration of the diaphragm 17. This will, in the manner of a horn, provide a loud audible signal, the sound emanating from the protective end grill 22. -v
Between the audible signal 12 and the batteries 15 I provide a manually operable switch means comprising in part the stepped contact cup 32 and a second contact `cup 35, the latter being also carried within the insulating sleeve 33 and being adapted to engage a center terminal post 36 of the adjacent battery 15. The insulating `sleeve 33 has. slots or notches 38 and 39, through which lin a formedV sheet metal slide member 42, which may be attached to the casing 10 by any suitable means, that shown beingV in the form of rivets. Completion of the circuit for the signal 12 is effected by connecting the remining wire 44 from the con 1s to the mem Acup zo which is grounded on the casing 10. It will be understood, as is also hereinafter disclosed, that the remaining terminal of the battery power means 15 is also grounded on the casing at all times. By Vthe above construction, the person carrying the protective device may whenever desired activate the signal 12 by shifting the button 41 into the position of Fig. 1, and may shutA olf the signal by returning the button to its open-circuit position.
In accordance with the present invention I also provide an automatic switch means for activating the audible signal 12, said automatic being responsive to any appreciable jarring or jolting of the casing 10. This automatic switch means is shunted across the manually operable switch means, and comprises a metal weight 46 carried by a metal coil spring 47 which is rigidly secured to thebottom of the contact cup 35. The weight 46 has an eye or loop 48 engageable with an insulating hook 49 which is secured to the bottom of the cup 32 and is constituted of an insulating material such as nylon plastic or the like. Normally, when the weight 46 is hooked as shown in Fig. 1, the automatic switch is open-circuit. However, if the casing 10 should be jarred or jolted it would disengage the'weight 46 from the hook 49 and the said weight would then rest against a ridge or shoulder 50 of the cup 32, by virtue of the spring 47 yielding under the force of the weight, thereupon electrically connecting the contact cups 32 and 35 and closing the circuit through the alarm device 12. The alarm will now be given, and may be shut off by standing the protective device on its end 11, in an upright position. Since such positioning of the protective device is extremely unlikely during a scuffle, or when the device falls to the ground, it is virtually impossible to prevent the alarm from being sounded once the weight 46 has become disengaged from the hook 49.
Also, in accordance with the present invention I provide novel means for energizing the flash light portion 14 of the protective device. This means comprises a metal tube or sleeve member 53 which surrounds the casing 10 and is insulated therefrom by an interposed insulating sleeve 54. On the tubular member 53 I provide a formed metal slide member 56 carrying a switch button 57 which has a connecting arm 58 extending through slots 59, 60 and 61 in the sleeves S3 and 54, and the casing 10 respectively. The contact arm 58 is adapted to engage a contact button 63 carried by the insulating sleeve 33 and the contact cup 35, such button being electrically connected to said cup. By this organization, shifting of the button 57 from left to right as viewed in Fig. 1 will cause the arm 58 to engage the contact 63, thereby applying an energizing potential to the outer metal tube or sleeve 53.
At the end 13 of the casing 10 I provide a removable cap in the form of an annulus or ring 65 having a lens disc 66 and a reflector 67 in which latter a bulb 68 is carried. The ring 65 has bayonet slots 70 cooperable with bayonet pins 71 of the casing end 13 whereby the cap may be readily applied to or removed from the casing. The cap also comprises a metal cup 73 secured to the ring 65 and having a coil spring 74 engageable with the bottom terminal surface of the end battery cell to effect a grounding connection from the battery power means to the casing 10.
In the cup 73 there is provided an insulating strip 76 carrying a contact member 77 engaged with the tip contact of the bulb 68, said member extending through a slot 78 in the cup 73 and engaging a contact stud 80 which is carried by the outer tube 53 and is insulated from the casing 10 by a bushing 81. In this manner a circuit is eifected from the tube 53 through the lamp 68 to the ground or casing 10, inasmuch as the reilector 67 is of metal and engages not only the shell of the lamp 68 but also the cap ring 65. f
It will be readily understood that actuation of the Cil switch button 57 may now eifect energizing of the lamp 68 from the batteries 15. It will be seen that batteries 15 may be readily removed and replaced by merely removing the cap ring 65 and ash light assemblage attached thereto, as made possible by the bayonet slot and pin connection between the ring 65 and the casing 10.
It will be further understood that, as effected by the above construction, I have provided a novel and improved protective device constituted to function as a night stick or club, said device having incorporated therein a flash light means and an electric, audible alarm means and further including an automatic switching arrangement by which a loud sound or signal will be given in the event that the device is suddenly jarred or jolted. The construction is relativelyv simple and utilizes few components which may be economically fabricated and assembled.
Variations and modifications may be made within the scope of the claims, and portions of the improvements may be used without others.
