LOCKING DEVICE FOR AUTOMOBILES. l

To all whom it may concern Be it known that 1, JOHN P. GERAGHTY, a citizen of the United States, and a resident of Jersey Cit in the county of Hudson and State of N ew Jersey, have invented a new and Improved Locking Device for Automobiles, of which the following is a full, clear, and exact description.

The object of the invention is to provide anew and improved locking device for automobiles and similar vehicles and arranged to prevent unauthorized persons from start ing and running the motor thereby preventing such persons from stealing the vehicle. Another object is to provide means within the hood inclosing the motor 'to prevent starting of the motor and to provide a locking means for locking the hood to prevent unauthorized persons from gaining access to such means with a View to prevent starting of the motor. Another object is to provide a plurality of devices for rendering various parts of the motor inoperative to prevent even highly skilled, unauthorized experts from running OH, with the car even if one of the said devices is rendered operative owing to the remaining devices being still in inoperative position thereby preventing starting of the motor.

With these and other objects in view, the invention consistsof certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming apart of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a longitudinal sectional elevation of the forward end of an automobile provided-with the improved lockin device,

Fig. 7 is an enlarged sectional side elevation of the permutation lock for locking the several devices when in operative "position,

and c. X Fig. 8 is a face'view of the same.

On the chassis 10 of an automobile or other vehicle is mounted the usual motor 11 inclosed within a hood 12 adapted'to be locked to the. chassis by interior locking devices 15, preferably two on each side, as shown in Figs. 1 and 2, but alike in construction so that it suflices to describe but one in detail. On the inner face of the hood 12 is secured a keeper 16 adapted to be engaged by a bolt 17 mounted to slide in a guideway 18 attached to the chassis 10. The bolt 17 is normally out .of engagement with the keeper 16and the bolt is'attached to or forms part. of a longitudinally extending rod 19 provided near its rear end with a pivot 20 connected by a link 21 withan arm 22 secured on a shaft 23 extending transversely and journaled in suitable bearings 24 attached to the transverse partition 25 forming part of the dashboard 26. The shaft 23 is provided with an arm 30 pivotally connected with the forward end of a link 31 extending rearwardly through the partition 25 and the dashboard 26 and through the footboard 32 formingpart of the dashboard 26. The rear end of the link 31 is pivotally connected with a pedal 33- pivoted at 34 to the footboard 32 and under the control of the operator in charge of the automobile. A spring 35 attached to the under side of the footboard 32 is connected with a collar 36 held on the'link 31 to normally hold the latter in rearmost position at therear end of the hood 12, the partition ion with the pedal 33 standing upright, as I plainly indicated in Figs. 1 and 2.. Each of the rods 19 is mounted .to slide in the lower portions of the bearings 18 to insure. proper engagement "of the bolts 17 with the keepers 16 whenever the pedal 33 is pushed forward and a rocking motion is given-to the shaft 23. which by the arms 22 and links 21 causes a forward sliding movement of hood 12 in closed position thereby preventconnecting the pipe 51 with the manifold 52.

ing access to the motor 11.

Within the hood 12 are arranged a plu-' rality ofdevices .controlled from the shaft 23 and connected with difierent members of the motor 11 for renderingthe latter inoperative by each of the said devices. As shown in the drawin s, use is made of a shut-off valve 40 arrange in the pipe 411 connecting the reservoir 42 with the carbureter of the motor, it being understood'that this valve 40 is normally in open position but is moved into closed position whenever the operator presses the pedal 33 in a forward direction. It is .understood that when the valve 40 is closed the supply of" the motor fuel is cut off and hence the motor cannot be run. .The valve 40 is provided with an arm 42 connected by a link 43 with an arm 4: 1 secured on the rock shaft 23 and hence when the latter is rockedon pressing the pedal 33 the valve 10 is moved into closed position for the purpose mentioned.

' The butterfly valve 50 arranged in the pipe 51' connecting the carbureter with the intake manifold 52 of the motor is provided with a rock shaft 55 on one outer end of which is secured the usual arm 56 connected with the usual controlling mechanism under the control of the operator for moving the butterfly valve 50 into open or closed po-. sition. When the automobile is stopped the butterfly valve 50 is usually moved into closedposition by the operator correspondingly manipulating the actuating device for the butterfly valve, and in order to hold the butterfly valve locked, when in closed position use is made of an arm 60 fulcrumed on a bracket 61 attached to the

flanges

62, 63

The free end of the arm 60 is in the form of a fork 65 adapted to straddle the arm 56 thus holding the latter against movement. thereby preventing opening of the butterfly 50, as will be readily understood by reference to Fig. 5. The arm 60 is pivotally connected by a link 66 with an arm 67 attached to the rock shaft 23 sothat when'the latter is rocked as previously explained the arm 60 is swung forward into locking engagement withathe arm 56 of the butterfly valve 50 thus holdin the latter locked when in closed position. t is understood that when the utterfly valve 50 is locked in closed position the motor 11 cannot'be started and run,

Another device in the form of a switch is provided for breaking the ignition circuit of the motor 11 thus rendering the latter inoperative. For this purpose use is made of a switch bar 70 mounted to slide up and down 1n suitable bearings 71 arrangedon the front face ofthe partition 25, and the lower endof this switch bar 7 O isprovided with a to the number of motor cylinders.

slot 72 engaged by a pin'73 held on an arm 74 attached to the shaft 23. Normally the switch bar 70 is in uppermost position but when the pedal 33 is pressed and the shaft 23 is rocked as previously explained then the arm 74 impartsa downward sliding moveinent to the switch bar 70. The switch bar 7,0'is provided with a crossbar 79 of an insulating material and on which are secured a number of spring contacts 80 corresponding I he spring contacts 80 normally engage contacts 81 mounted on the partition 25 and connected by wires 82 with a timer connected with a source of electrical energy. The spring contacts 80 are connected by wires 83 with the spark plugs of the'engine cylinders. It will be noticed that when theparts are in a normal position, as shown in Figs. 1, 2 and 6, then the wires 80 are electrically connected with the wires .83 to insure proper ignitionof the explosive mixture in the motor cylinders in the usual manner, but when. the pedal 33 is pressed forward and a rocking movement is given to the shaft 23 then the switch bar 70 is moved downward whereby the spring contacts SO-move out of engagement with the contacts 81 thus breaking the ignition circuits for the several motor cylinders and thereby rendering the motor inoperative. Normally the several devices are in inoperative position and are only moved into operative position on the operator pressing the pedal 33 in a forward direction against the tension of the spring 35,

it being understood that when this takes place the hood 12 is locked, the valve 40 is moved into closed position, the butterfly valve 50 is lockedagainst movement, and,

the ignition circuits for the several motor cylinders are broken. Hence, the motor is rendered inoperative and the hood 12 is locked by the interior locking device thus preventing access to the motor and the sev eral devices above referred to.

In order to hold the bolts 17 in looking position, the valve 40 in closed position, the arm 60 in locking position, the switch bar 70 in circuit breaking positionand I the pedal 33 in forward position, use is made of a locking bolt adapted to engage an aperture 91 formed in'the upper end of the switch bar 70. The bolt 90 is, mounted to slide in a casing 92 mounted on the partition 25 and the dashboard 26, and the bolt 90 is pressed on by 'a spring 93-to normally hold the bolt in rearmost position, that is, ,out of engagement with the switch bar70. The rear end 94, of the bolt 90 roj'ects beyond the face'of the dashboard 26 and is adapted to be engaged by a locking arm 95 pivoted on a bracket 96 attached to the face of the dashboard 26. Immediately after a forward swinging movement has bee g v n t the p al 33, as above derear end 94 of the boltl90thus pushing the scribed, the operator swings the locking arm 95 upward into engagement with the latter forward and into engagement with the aperture 91 of the switch bar 7 0 now ,in lowermost position, thus locking the switch bar in this position. It is understood that when the bolt '90 engages the aperture 91 the switch bar 70 is locked in lowermost position, and as this switch bar 70 is connected with the rock shaft 23 the latter and the several devices connected therewith, including the pedal 33, are held in locked position with the several devices in operative position.

When the arm 95 is swung upward its free end 97 engages a locked frame 100 attached to the upper portion of the dashboard and thisframe 100 forms a part of a permutation lock of any approved construction, but preferably of the construction more fully shown and described in the application for Letters Patent of the United States, No. 291,028, filed by me on April 18, 1919. The permutation lock is provided with a looking slide 101 adapted to'engage the freeend 97 of the lockingarm 95 to lock the latter in closed position, and the said-locking slide 101 is controlled by tumblers 102 mounted to turn on the frame 100. and provided with the usual letters, numerals and other characters (see Fig. 8) to permit of setting the tumblers to any desired combination and which combination is only known to the operator in charge'of the vehicle and hence unauthorized persons cannot'open the lock and release the arm 95. -When the operator in charge desires to start the vehicle, he sets the tumblers 102 to the predetermined combination thus unlocking the arm 95 and allowing the same to swing downward intov unlocking position thus releasing the bolt 90. The latter now returns by itsspring 93 to rearmost position thus disengaging the switch bar 70. When this takes place the several parts return to their normal inoperative position. by the action of the spring connected with the pedal link 81. It is understood that when this takes place the hodd 12 is unlocked, the valve 40 moves into open position, the arm 60 disengages the arm 56 of the butterfly valve 50, the spring contacts 80- move into on gagement with the contacts 81 thus closing the ignition circuits, and the pedal 33 returns to normal uprightposition.
