Application led. January 11, 1926. Serial No. 80,403.

rllhis invention relates to, alarm apparatus, and more particular-ly to7 an. apparatusk which is primariltyT intended' for application to moter vehicles for the purpose of apprising the "i owner and others that an attempt is being circuit connected in the primary circuitv and;

having one or more-concealedl switches interposedA therein. whichl when momentarily closed; will' cause the: operation of the alarm, and'f said circuit alsoincludingmeans wher-ef' by the sounding oli the alarm wilt continue even: though` the switch be again opened. o

tzi'sone of' the importantv objects ofthe invention to provide` a. single manually operable part for operatingv` the makel and, breal device in the primary circuit toopenthe same', said-fpart forming a partot the alarm operat-y ing circuit` andi coactingf with key controlled means to cause a. breakV in said circuit. This l'rey actuated means is so.y constructedand arrangedthatit is not necessary to: employ the key for closing the alarm. operating; circuit, t-lie use of the key' beingrequired only in orden` torelease said. manually operable part for thev urposel of opening the alarm circuit i andi closing the break: inthe primary circuit.

Et is4 another important object of the ini ventionitofprovide amaking andbreakingde.-

vice for tliealarm circuit as above reerredtO which. i's-v so constructed, mounted and arranged. that after it has once been operated4 by the push button or other manually operatedl to close thel circuit, it is impossible to open said circuit to. stop theV operationv of the without the use of the proper-:key

It may also provide an additional switchv for closingthe alarm` circuit operated: upon? Vthe. insertion of the key to-fopen they-alarm, Cu?

cuit whereby said alarm device willg'be momentarily operated prior to openingofitsA circuit, thus warning the owneneven though the proper key be usedathatanattemptat theft ofthe vehicle is being made.

ductor with the binding post 6. `The remaining binding post 7 isV connected by. coiiductoi" 51 withv a contact?J opposed to the Contact 49.Vv

The part 19 is normally urgd in Oh reotion to anormal positioiibya coilfspring v53, in'which position of saidA parts, contacts 36n and 37 are engaged for closing the igni'-; tion circuit.

For the purpose of operating theplat'es 25l and l26 to permit the returnof said-part to its normal positi-onand the breaking of the alarm circuit at thecontacts 49 1 and 52,1 provide a pin tumblerlock 54 'so Y '9o J mature being provided ,withv a' contact pin 49 j ninsulateditherefrom and connected by con-Q of any conventional type suitably mounted in the dashboard` D of the .vehicle andV havingits barrel connected by arrod 55V with the intermediate".pivoted or hingedv plateY 28./

Thus, it willvbe app-arent that upon, the in'-y sertion of theproper key and Ythe rotation of the lock'barrel .the plates 25 and 26 may be moved' with respect to'` the-partVV 19y so,y Vasl to di'sengage shoulder 30V rom; theend of the armature and 'the a`rmg31 of;.1plate V26 from the notch 34 of the partrv 19. f' .a

'As shown kin Figs. 10` and 11 of thedraw ings, I maygprovide Van `additional switch connected inthe lines 1 and Qand closed by the'lock key 56 so as to momentarilyclose the alarm circuit when thelrey .is inserted and beforeV Yrotating Y the lock.y barrel.v y As` shown, thrisvs'witchA may'flconsist of opposedv 'p fixed and movable contacts 57 and 58 respec-V tively, the'contactf58 being resiliently held ina normal open position ian-d provided with' -a pinror stud 59-movable throughv an Vopening inl the wall of thelockv Caseland normally projecting into the :key passage-of-the lock barrel Y Thus, this pinor stud will lock the Gui Cil

the proper key 56 is inserted, the pin e59 will he forcedoutwardly, thereby engaging ,con-y tact A58 with the contact 57V andl closing the circuit so that the alarm device'12 will be sounded in a manner whichT 'shall now eX- p'lain.

ln the normal operation of the vehicle equipped. with my new alarmapparatus,.the parts are in-the relative positions' shown in Fig. 9 of the drawings, with the contacts 86 and 87 engaged with each other while v.the insulation 32 on therarm 31 of the hinge plate 2G isengaged withthe part 19. Thus, when the'ignition switch'll is closed inthe usual way, the current flows from battery A 10 through conductor 9 to the post 5 and along the conductor 1 38 through contacts 36 and 37 and conductor bar 35 and post 4 and hence through conductor 8 to the ignition apparatus and from the latter tothe ground.

lVhen the owner or operator of the vehicle leaves the same unattended, he merely 'pus ies upon the button 24, and thereby rocks lever 22 to force the part 19 inwardly. TheA end of this part bearing against the lug 39 `disengages contact 36'from the contact 37 and thereby breaks the ignition circuit independently of the switch 11. At the same time, the notch 34 in the iiange of said part 19 moves beneath the arm 31 of plate 26 and this arm is urged downwardly into said notch by the spring 27 so that the opposite'end edges of the notch are engaged with the side edges of said arm. The parts are now in the position shown in Fig. 1 of the drawings. Should the ignition switch 11 now he closed in the attempt by one contemplating the theft of the machine to operate the same, the current will flow from the bat tery along the conductor 9 to the post 5 and fie conductor .38 to the post 40 through con- .uctor 43 and the windings'of the magnet 16 to the screw along the strip 47 to the post 41, thence along conductor 44 to plate 26 through part 19 to hraclret 17 and the wall of the casing or housing to the ground. Thus a circuit energizing the magnet 16 is completed whereupon the armature 48 is attracted to engage contact 49 with contact 52, the armature heing locked in such position by plate 25, the shoulder o0 of which drops behind the end of the armature. This condition of the parts is shown in Fig. 3 of the drawings, and in such movement thereof strip 47 is disengaged. from the screw or pin 46 and the current from the battery now flows through conductor 14,

post 7, conductor 51, contacts 52 and 49 and conductor to post 6 and hence to the grounded horn 12 or other sounding device. It will he observed that such circuit is entirely independent of the ignition switch 11 so .that if ythis"switch ihex` again opened, (the. horn will nevertheless, continue Atosound. The same. .condition willV ,obtain4 in thel eventi that .any one of the .other switches interposed in the lines .1 and 2 is opened and thenlsubsequentiyclosed. In orderto stop .the operation of the alarm, the 'proper key is inserted inthe,

lock and 4the lock barrel given a half turn, tlierehydisengaging .parts ror latching devices 25 -and26 from .the armature48 `:and vpart 19 re' specti-vely. AThe spring 5,3 thereupon retracts;

and :returns saidv pant to its :normal position i while fthe contact 3&6 again (engages :the contact 37 .to close .the ignition circuit. Before Withdrawing the key, the rotation of the lock lbarrel is reversed, thus permitting the springs 27 to actupon plates '25 and 26until the insulation 32 of the latter .plate engages upon the part 19.; J

From .the foregoing, it will he seen ythat .I have materially improvedV the .apparatus shown in .my former application .and have eliminated the necessityxof Ausing the key in order to place .the parts in condition to 'close the alarm circuit, suchfoperation heingin, stantly performed merely by the pressure of the nger upon the push button 24. Since l mount the entire apparatus. upon the 4under,

sidek of the dashboard, it isentir-ely inaccessi-y ble `and by ingeniously concealing the various switches,it becomes practically impossible for one contemplating theft of .the vehicle to ac* oomplish hisl purpose without operation Of the audible signalling device. vWhile I have particularly referred to the alarm apparatus as intended for use in connection with motor vehicles, it is possible that the essential features of the invention might also :be .advantageously employed in various Lother connections and for different purposes. Accordingly, it is to he understood vthat I Areserve the 4privilege of adapting the dev-ice to such other uses and also the right .ofincorporating the novel =features 'thereof Vin various vother V'alternative structures .and adopting all suchleg-itimate modifications in the form, construction `anc relative arrangement of the several parts as may be fairly .embodiedwithinthe spiritrand scope ofthe invention as claimed.
