To all'lwliom tmay concern.' t

lle. it. known that I, Enwaao R. Moolnziaa citizen otA the United States, and a resident at' Albany in the county of-Albany and State of hcw York. have invented a new and Improved Safety Locking Deviceifor` Vehicles` of which tliefollowing is uV full, clear. and exact description.l

The invention relates to automobilesl antotruchs, acroplanes and similar vehicles iising internal combustion engines as the motive power. 4

'l'he ohjcct of the invention is tolproride a new and improved safetyflocking device for such vehicles,arranged to prevent an unauthorized .person from startin and runnin, r the niotor. Another ohjectis to permit at' conveniently applying 4the llockingdcvico in vehicles now in use without .materially altering the construction thereof. Another object. is to sound an alarm whenever an unauthorized` person tampcrs .with the safety locking device.

In order to accomplish the desired result', use is made of an ignition circuit, an alarm circuit and a scriesof button controlled rwitches. sundry selected switches heini: in operative relation with the said ignition cireait and the remaining switches being in operative relation with mechanism controlling -an alarm switch in the alarm circuit to close the, latterand sound an alarm whenever sui-h alarm switch is moved into active position h vnan, unauthorized persen. `,Uso is also made of locking means to' lock tho actuated alarm `switch at i'ton'iatically in aetire position, to continue soundin of the alarm on release ofjan actuated switeli,.ai"id a Ice r controlled mechanism connected with the alarm switch torcturn tliclatterto nor-r mal open or. ii iactivc positiph. f

When thclt driver on leaving the car turm the key 118i; i in tho rcversedircctioa then the contact 1l-1!:80 mot-cs out of engagement with thc contat-tsv to break the Ignition circuit at this pointa'i and tite Switch lever 1li! also exerts a puliti on the ofl'set 111 thus canning.` the lever 10u. to im art a Sliding movement to thc slide-85" 100 w terehy the link 105 imparts` a rocking: motion tn the corresponding shaft 101 where-.t by both shafts 10| aro rocked and the :troisA` 100 impart a swinging motion to the look-1'` ing catches liti to release all the arms 5T that, 90 may havo been in locked position. Wheat this takes place the-switch levers 40 retnrir. to their normal inactive position by the :io-Q` tion of their springs 52 and the ignition cir-.1 C cuit is further broken in three plat-cs. .196 Ono of the shafts G3 (sce Fig. 3) is provi vided with a switch arm 120 provided with! au insulation 121 ou which in mounted a con-1 tact, 122 adapted to pasa between two springt f; contacts 123, 124, of which the contact 12J-15100 forms mrt of the. adjacent contact 47. lfff all tho-y atttons 23 are simultaneously pressed; br an unauthorized person it causes the con-i tact 122 to swingout of engagement witht it the contacts 123 and 124 thus breakingT the' las ignition circuit also causing the contact 78: to swing into engagement with the contacte and causingthe alarm. to sound.

Tho magneto and batter;y buttons 9.4 and a 25 are arranged to control one the other.: that is. when one is pressed the other is; released and vice versa. For this purpose: tito following arrangement is made. special reference being' had to Figs. 2, 3 and 6: 'The button 24 is mounted to slide in a bracket, attached to the front plate 22` and the' button is provided witha reduced portion: 131 on 'which is coiled n sprintf-132 resting witlroneendontho bracket. 130 and pressin with its other end -on the button Qtto' the lattrrfnortnnlly in forward position.` -'On the reducedportion' 131 is formed a nlotrlatlapted to engagea switch .ievor' oa back plate- 82.' "On the-lever 126 134 is seeuredan insulation 136 supporting a contactladapted to passhetween two npxfingcontact's 138 and 139 held on the book plate 82. Thebattery button 2-'iis proat vided with tt reduced portion on which 1:10

is coiled aI spring 141 nesting` with one and on the bracket 142 in which the button and its reduced portion 149 are mounted .to slide. The reduced portion is irovlded with a slot 143 engaging a switch ever 144 full the arm 154 is adapted to engage the springpressed tail 156 o a catch 157 mounted to swing ona bracket 158 attached to the back plate 32. The. catch 157 is adapted to engage and lock the switch lever 144 in ositon at the time the contact 147 engages th contacts 148 and 149. Tho arln 155 on the shaft 153 is adapted to engage the springprcsscd tail 160 of a catch 161 `fulcrnl'ned on n. bracket..162 attached to the back plato 32. The sprin catch 161 is ada ted to engage the switcliy lever 134 contro led by the magneto button 2410 lock tho said switch lever 134 in place at the time its contact 137 engages the contacts 138 and 130. fThe tails 156 and 160 are each pressed on by a spring 163 (see Fig. 3) to hohl the corresponding catch 157 or 161 in engaement'with their corresponding switch lever 144 or 134. It will benoticed that when the button 24 is pressed the contact 137 swings into engagement. with the ' contacts 138 and 135 und at the same time tho free end of the lever 184 engage the arm 150 and im `arto a swinging motion to the same there y roeklnfg the shaft 152. .The rocking of the sha t 152 causes its arul 154 to engaze tail 156 of the catch 157 w iereby tie latter moves out of en 'agement with tho switch lever 144 thus re. easing the latter. The action nf the spring 141 on the button 25 and its reduced port ion 140 now causes the switch lover 144 to swing forward 'whereby' the contact 147 moves ont of engagement with the contacta 148 and 140. Tn a similar lnnu ner when t.he button 25 is pmtsed the contact. 147 moves into engagement with the contacts 148 and 140 and at' the same titllne4 1o.

the switch lever 1,84 is .released and s )ring 182 returns the switch lercr 134 and the' button 24 tov normal innctivmposttion.

The' forward movements ofthe buttons- 114=` mthlcitlwcthe magneto 4or the battery on and 25 are limited-by stop pins 165 ,andltl adapted'4 to *ah'uttv ngainstf-the' bracket! F7150 and 142.1: The cont and 178, and' the connected contacts 180 and presa the acts 138 and .Mnarq'connecticii b wires 170 and 171 with lnndmg postll 2.

and 141) are connected by n wire 174 with one of thc end contact plates 48, as plainly shown in Fi 10. The opposite end contact platefl is connected by a wire 175 with a bindingpost 176, and the binding post 172 is connected b a wire. 177 with a niagncto, and thebuu mg post 176 is connected with the wire 178 ot the ignition circuit which has its other wire 170 connected with the battery clrcnit 86.

The operation is as follows:

When the several parts are in the position shown in4 Fi 1, 2, 3, 4, 5 and 6 and the keys 1,18 an( 96 are removed then the ignition circuitis open. When an unauthorized person now presses any one of the buttons 23 other ythan those in the combination 3, 0 and 410 it ca nses the corresponding 'switch lever 40 to be actuated whereby the alarm circuit is closed, as previously explained and-thc alarm is sounded. As the actuated switch leveris locked against return movement by the spring 83 it is evident that the alarm A81 keeps on sounding and the unauthorized person 1s foiled in closing the ignition circuit and hence is not able to start. the engine. The sounding of the alarm naturally attracts tho` owner ,of themachine who.. by insentln th'ekey 06 and actuating the' i'ilechnnism 2 causes the switch lever 74 to move out l? engagement with the contact 70 to break the alarml circuit. When the driver desires to start it is necessaryr for him to press the buttons 23 in the combination, that is,.thoso`1narkcd 3, i) and 11),

where-by the corresponding switch levers 46 close the gnitioncircuit at thc corrcspondf ing ips, and when the driver now inserts the ey 1 18 and turns the same then the contact 114 is moved in engagament with the contacts 115 to finally close the ignition circuit thus allowing starting of the engine.

The key 06 may be withdrawn by the driver but the key 118 remains in osition and when thc driver leaves the mac xine he turns the key 11 8 back to the witlulrawalI position and removes it thus moving the contact 114 out of engagement with the contact and atthe saine time the set switch levers 40 ale released and return to their normal-inactive.

position'.

It will noticed that'fthe unauthorized nmin ignition circuit at the contacts 11 and 115, al previously explained.

Itis understood that. thel driverean startpressin thscorrespondiug button 24er 25. It w, ll be Anoticed that r incaseA an ,unam

l' is understoml that th" .lriver of the vehicle can readily change the combination by chan ingI thel posit-'ons of the corres onding num vera 43 of tle switch levers 4( and removing the isciewi4 51 from -between the eorres|mndinr plates 50.

Although uit thiee buttons marked 8, 0 and l0 are in the combination shown and described it is cviilent. that the locking device can bc set with more or lese:A buttons in the combination.
