Application filed January The invention has for an obj ect'to provide a simple form of combination controlled lock that locks, in open position, a compound switch controlling the spark plug circuits of the engine, and which also serves to lock the emer ency brake lever in position with the emergency brake set.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the. invention are more particularly set forth.

.Fig. 1 of the drawing is a plan view showing the device as in position on, an automobile, the cover ofthebox or housing being thrown back.

Fig. 2 isa side view of the device as applied. p i

Fig. 3. is a longitudinal sectional view of the device, this view being taken ,on the line 33 of Fig. 4.

Fig. l is a horizontal sectional view taken on the line 4-4 ofFig. 3 and looking upward. 1 1 t Fig. 5 is a detail plan view showing more particularly the compound spark plug control switch. r

Fig. 6 is a transverse sectional view taken on the line 66 of Fig. 5.

Fig. '7 is a fragmentary horizontal section taken on the line 77 of Fig. 3.

My improved device comprises a box 10 that is fixed to the automobile floor in front of the drivers seat, a portion of the said floor being indicated at 11. Extending across this box 10, approximately mid-way of its height, is a horizontal partition 12 below which are the lock and switch mechanisms, while the knob 14 for the combina tion lock, and the handle 15 for throwing the locking bolt are supported by and above this partition, the numbered dial, with which an anti-thief lock:

19,- 1925. serial No. 3,473.*-

the knob 14 co -operates, beingshownat l on the partition. l

The handle l5is fixed on the upper' end of a spindle 20 extending through, and-r0 tatable in, the partition 12, this spindle having fixed to its lower end an angular lever 'arm. 21, onearm21 of which is engaged .in

a notch 22 in a; switch operating plate 23,

while the other arm 21 is engaged by the ,bolt 24 of the lock,.this arm'havingan' angular recess 25 in the end thereof that engages the'end of the-bolt, the swingof the arm being transverse to the direction of movement of thebolt, the latter beingslidable in a casing 26 containing ordinary lock mechanism controlled by the knob 14;

The switch operating plate 23 is sli'dable in the box 10, under the partition 12, and is guided partly by a headed screw 30 passing, through a slot 31 in the plate and screwed 'llltO the partition 12Land partly by means of a projecting pin 32 fixed tosaid plate 23 and engaged inan aperture in a transverse j rib 34 depending from the partition12and to which further reference will presently be, The switch operating plate: 23 is provided at one end with a transverse cross. piece 23 which has attached thereto one end; 7 ofia rod 38 that extends parallel to the di,-

made.

rection of ,movement of .the plate.-.-To the;

other end of this rodv is attached; a com- 5 pound bridging elementalined with said-rod that bridges contact members formingypart of the individual circuit to the various spark plugs of the automobile engine- These contact members comprise the studs-40v that are.- sunk in a pair of, elongated insulating baseblocksAl between which the. said bridging l element extends,these studs having their a djacentends roundedas shown and projectj 1 ing slightly beyondv the vertical surfaces of l the blocks. .Conn ected to these stud s,., as T shown. are the vertical binding screws 44:- to

which theleads to and ,from the spark plugs:

connect. "The contact supports 41 may be mounted on a bracket fixed to the bottom of the box and having upturned ends 46 which are ape-rtured, the one to receive the end of the rod and the, other to receive an extension 46 from the other end of the contact bridging element whereby the latter is guided for movement between the rows" of contacts.

This bridging member is in the form of a The member 48 is: normallys-urgedto a posi-- tion with'the studs-thereon to engage the respective pairs of studs by means of a coiled expansion spring 50 surrounding the, rod 38 and bearing on a collar 51 fixed thereon, the movement of the said member, under the influence of the said spring being limited by a nut and washer element indicated generally at 52 that bears on the end of the bracket:4;6.

Referring now to the rib 34: before mentioned-as depending from'the partition 12 and: apertured to receive the pin 32 on the plate 23, the said rib is formed with a'socket 55' that. is entered longitudinally thereinto fromst'heside of the casing and in which is slidab'ly'positioned a flat bar 56 that has 'a'hole 57 therein, near its inner end, through formed with another aperture or hole that receives a: stud 57 on the side of a collar 58 that freely surroundsthe emergency brake lever 59- thereby locking the said lever in place. The box may be provided with a sliding cover made in sections 60 that overlap one another when the cover is opened, and may have an electric lamp 61 in the top compartment thereof to enable the dial of the combination lock to be seen at night.

' In connection with my improved: attachment I preferably provide aedevice thatensures of-the release of the emergency brake lever'before the bridging element 48 is moved sufliciently toclose the ignition circuits.- "-As' shown in, Fig. 7 the pin- 32 is formed with a notch 65 in whichisadapted to:be engaged a spring pawl 66 secured on one end of an angular rock lever 6'? whose other end'projectsthrough a slot 68 in the rib to: bear on the: bar56, a weak tension 'plate'23', sulficiently to disengage from the spring 69- being connectedtothis lever and urging it in a direction to move the pawl 66 away from the pin 32. When the bolt is released the pin 32 may be moved with the bar' 56 before the pawl 66 rides into the notch 65-, at" which point the contacts of the ignition control device are not as yet bridged, The bar 56 must then be with- 5 drawn, to allow the lever 67 to swing under ranged; in pairs forming part of the ignition circuit of the automobile, a slidable bridg ing element adapted to engage and bridge the contacts of the respective pairs, a collar adapted to freely surround the emergency brake lever of the automobile, a bar connected at one end to the said collar, apin movable with the said bridging element and engaging in an aperture in the said. bar to retain the same against movement, and a lock controlling the movement, ofthe said pin and bridging element, and means pre venting complete movement of the said bridging element to operative pos1t10n when the said pin is engaged with the said bar.

2. An anti-thief attachment for automobiles comprising a series vof spaced contacts arranged in pairs forming part of theigni-tion circuit of the automobile, a slidable bridging element adapted to engage and bridge the contacts of the respective. pairs, a collar adapted to freely surround the emer-, gency brake lever ofthe automobile, a bar connected at one end'to the saidcollar, a pin movable with the said bridging element andengaging in an aperture in thesaid bar to retain the same againstmovemenhand a lock controlling the movement of the said pin and bridging element, and means preventing complete movement of the said.

bridging element tooperative position, when the said. pin is engaged with the said bar, comprising a lever, a pawl carried by said lever andadapted to engage in a notch in the said pin, said lever having a part .projecting into the path of the said bar whereby the lever is retained by the said bar in position with the saidpawl bearing on the said pin.
