Serial No. 183,144. Renewed October 2, 1929. Patent No. 1,759,462, dated aMy 20, 1930. Application for reissue led April 12,1932. Serial No. 604,841.

This invention relates to controls and locks therefor, and particularly to apparatus for preventing the unauthorized use or theft of an au tomobile.

This application is a division of my copending. application, Serial No. 130,615, filed August 21, 1926.

One of the objects of the present invention is to provide a controller which may be unlocked by the use of a key, but movement of the controller to operating position 1s prevented so long as the key remains .in the lock. Preferably, the controller includes means for automatically moving the operating member of the controller to operating position when the key is withdrawn from the lock. The invention is susceptible of many appllcations, and, when applied to an electricswitch, -the objects of the invention are accomplished by providing an electric switch with means such as a spring tending `to move the movable contact of the switch to closed position, a key operated device for releasing the spring and a Adevice which permits unlocking the switch, but prevents complete movement of the switch to closed position, so long as the key is in the lock. Consequently when the key is removed the switch will be ,automatically moved by the spring to closed position.

A further object of the invention is to provide a combined switch and lock comprising separate unitary subassemblies, one of which includes an operating member'nd lockutherefor and the other of which includes the complete switch. lVhen these sub-assemblies are joined together, the operating member of the switch will be positioned for operation by the operating member of the controller. y A furtherl object of the invention is to providea unitary ignition coil, -ignition cir Cuit switch, controller for the switch and lock therefor including novel features such yas mentioned in the foregoing paragraphs.

Further objects and advantages 'of the 4.present invention will'be apparent rom' the following description, reference being had to the accompanyinlr drawing, wherein a .preferred form of em odiment of the present invention is clearly shown.

In the drawing:

Fig. 1 is a front View of a unitary lock and switch constructed in accordance with the present invention, the rectangle drawn with dot-and-dash lines representing the instrument board to which the structure may be attached. t

Fig. 2 is a longitudinal sectional view on the line 2 2 of Fig. 1.

Fig. 3 is a view similar to Fig. 2 showing certain parts in positions differing from the positions shown in Fig. 2.y Y Y Fig. 4 is a-sectional `view on the line 4-4 of Fig. 3.

Figs. 5 and 6 are sectional views taken respectively on the lines 5 5 The. controller and lock therefor which comprises one of the unitary sub-assemblies of the structure shown in the drawing will first be described. This controller includes an operating member comprising an endwise movable member 20, anda cupped disc 21 carrymg a metal stud 22 surrounded by a non-conducting tube 23. As will appear more clearly hereinafter these parts to 23 constitute the operating member of theconltrller although the member 20 might be referredto as the operating member, and the 'parts 22 and 23 collectively as means for transmitting motion from the member 20. The members 2O a slidable within a tubular 24 which together with a tubular outer jacket o erating udp 21 are 25 and a plate 26 provides a case and support.

for tlie operating member and' lock of the controller. The jacket 25 is provided with an inwardlyextending flange 27' which engages a shoulder 28 of the guide 24,.and with a plurality of tangs 29 which extend through holes 30 in the plate 26 and are `bent over so asto secure the casing members 24, 25 and 26 in' assembled relation'. A screw. pin 31 extends through the members 25 and 24 in order and 6 6 of Fig. 2.y

guide or. bearing to prevent relative rotationl between them.

Rotation between members 20 and 24 is prevented by .providing the member 20 with an elongated groove 32` which receives the inner endof aiscrew 33 which is threaded into a tapped hole extending through the side wall of the'member 24.

The-operating member 20 is locked 'coiled .around the shaft 51, one end bearing in -non-operating position shown in Fig. 2 against Ya pin 55 attached' to member 20'and by a bolt 41 which is adapted to enter a the other bearing against'a side Wall 56 of recess 42 in a Side Wall 0f the member 24. the cover 52. The spring 54 is biased so as The bolt 41 is slidable within a recess 43 to tend to move the` cover 52 in a countel tion by a'spring 44. The operating member. ythe movement of the cover is limite by en- 20 carries a rotatable key barrel or cylinder gagementy'with the stop 55. Whenthe key 45 which can beturned only by the proper key 46 is inserted in the key operated member or indicated at 46 in Fig. 3. The-mechanism fOr cylinder" 45 the cover 52 will be movedv from causing the bolt 41 to be withdrawn fromrthe the full line position shown in Fig. 1 to the recess 42 when the key cylinder 45 is rotated position 52 (indicated by dot-and-dash lines has been omitted aS illustration thereof lWill in/Fig. 1) and the stop 5() will be moved from be unnecessary to those skilled in the art. //t/he full .line position shown in Fig.' 5 to the will be understood, however, that the par position 50a (indicated by dot-and- dash lines 20, 24, 41, 44 and 45 are comprised-in/what in Fig. 5).` Therefore, the inserting of the is known to the trade as the automobile type key 46 in the lock lwill cause the stop 50 to cylinder lock. It will be' understood that move into a recess 57 provided by cutting when the cylinder 45 is rotated by the key the away a portion of the side wall of the casing bolt 41 will be withdrawn from the recess member 24.' The recess 57 is Ofsuch width 42 thereby ,releasing the s ring 40 in 4order to relative to the thickness 0f the Stop 50 as t@ cause the operating mem r 20 to be moved permit movement of the operating member toward the left, until the right hand end of l20 from thevposition shown in Fig. 2 to that the groove 32 engages the inner end of the shownin Fig'. 3, the cylinder 45 having been screw 33. After lthis movement has taken turned by the key 46 to withdraw the bolt place the key 46 may be released to allow the 41- from the recess 42. Therefore, so long as spring 44 to move the bolt 41l against the the key 46 remains in the key cylinder 45 the interior surface of the casing member 24. operating member cannot move the fulll Then the key 46 may be withdrawn. The amount toward the left into operating posioperating member 20 may be moved toward tion.l When the key. 46 is withdrawn the the right into non-operating position and spring 54 will be released to return the co'ver locked in said position without the use of a 52 and the stop 50 to normal position as inmaintained in position entirely within thekey., It will be apparent that when the opdicated in full linesin the drawing, lthereby y erating member 20 has been moved so that permitting the spring V40 to complete the will be in alignment with the movement of the operatin member 20 Itorecess 42l the spring 44 will automatically ward the left ory until the rlght hand end of move the plunger 41 into locking position. the groove 32 engages the .inner end of the In order to compel' the -o'eration of the screw 33. controller to remove the key efore the oper` While the controller-may be used to operating member 20 can be moved fully to opernte various sorts of mechanism particularly ating position, means operated b the keyl for rendering some essential part of an autoare provided for preventing the ull movemobile operativeor inoperatlve, the form of. ment of the operating member204 toward the control which has been illustrated is particleft or into operating position while permit- `ularly adapted for controlling an electric ting the'bolt 41 to e withdrawn from the switch which may be included alone or with the operating an ignition coil in a unitary sub-assembly member 2O to be moved a limlted amount so which is-adapted to bepattached to the plate that the locking bolt 41 will be held in un- 26 formin locked position by engagement with the insub-assemly. v terior wall of the casing member 24. This The sub-assembly y includinl the electric key-controlled device comprises a-movable switch for an ignition coil'wi now be destop 50 which is located with a recess 51al proscribed. The yignition coil comprises a cenvided in the right end of the operating memtral magnetizable core 60 surrounded bv secber 20. The stopv 50 is attached to the ondary coil 61 nd a rimary c oil 62. These squared end of the shaft 51 which extends coils are suriinded y an external magnetic through andA is rotatably :supportedby the circuit 63 a all of these parts are housed 20. The left end orexwithin avcontainer which comprises a metal the plunger 41 operating member posed end yof the `shaft 51 4is also square and tube 64 attached to non-conducting end mem-- i is attached vto a. cover. 52 for the key hole -53 ers 65 and 66. 'The member 65 carries ter- `mai n. minals 67 and 68 connected'withithe Sends of 53 as the primary coil 62, respectively. The ter- 50 is minal 68 is connected with the outside end of of the cylinder '45. The cover 52. is tained in position covering the key hole shown in Figs. 1 and 4 and the stop a partof the controller and lock mais? the secondary winding 61 and its inside end is connected with a terminal 69. One of the turns of the primary winding 62 is cut to provide leads 70 and 71 which extend through hollow rivets 72 and 73, respectively, and are attached to switch contacts 74 and 75, respectively. The rivets 72 and 73 secure said contacts 74 and 75 respectively, to the member 66. Member 66 is provided with a recess 76 for receiving a non-conducting tube 77 having diametrlcally opposite notches 78 and 79 for receiving, respectively, the inner ends of the switch contacts 74 and 75. The contacts 74 and 75 "maintain the tube 77 within t-he recess 76; and, since the inner ends of these contacts fit somewhat snugly within the notches 78 and 79, rotation of the contacts 74 and 75 with respect to their attaching rivets 72 and 73, respectively, is prevented.

The stationary contacts 74 and ,7 5 are adapted 'to be engaged by the outwardly ex-l tending ilange 8() of a metallic, cup-shaped switch operating member 81 which is located within thevtube 77. A spring 82 tends to contact opera-ting member.

urge the contact operating member 81 outwardly with respect to the recess 76 and its flange 80 into engagementwith the'contacts 74 and 75. It is therefore apparent. that.'

these contacts will maintain'the contact actuator 81 within the tube 77.

The non-conducting end member-66 is supported bya metallic coil housing end member which is attached at 91 to the coil housing tube64 and which is provided with an aperture through which'a portion of the non-conducting member 66 extends-as shown in Figs. 2 and 6. A case or. support for'the switch is provided b the member 66 and 90 and by a.` flanged tuliularmember or collar 92 which is permanently secured to the metal coil housing tube 64. The collar 92 has an outwardly extending flange 93 which-visv adapted to be secured to the gplate" 26 by rivets 94 and rivet studs 95. Itis therefore apparent that the parts 66, 90, 92and 26 will y provide a housing fortheswitch.v

Like the controller and" lock,l the ignition 'coil and switch may be constructed as a separate sub-assembly. When ythe controllery and lock sub-assembly is united to the switch subassembly, the operating member of the c ontroller will operatively "engage the switch semblies may @be readily disassembled by shearing olf the riveted portions in case repairs or displacements of either sub-assembly are desired.

The studs 95 are providedwith'tapped holes 96 for receiving screws 97 by which' the structure may be attached instrument board'98.

The operation of the controller with respect to Vthe switch willnow bel described. When the controller is in locked positionas shown in Fig. 2, the switch Contact flan'ge180 lthere y breaking the circuit of the These subr-asto the back .of an is se arated from the contacts 74 and 75,

rimary winding ofthe lgnition coil. Thellslnge 80 is spaced from the end wall of the -recess 76 so as to permit complete movement 'oi the operating member- 20 to locking position While at the same time allowing for variations in manufacture. When the key.46v.is inserted in' theJ cylinder 45 and turnedto withdraw the bolt 41 from the recess 42, the operating member 20 will be automatically moved by the spring 40 into'the position shown in Fig. 3 wherein the locking bolt'41-is held in retracted position. Due to the engagement of .the stop 50 with. the wall 57 defining the recess 57,` movement 1of the operatingl member 20 is arrested and hence the contact llange 80 cannot engage the switch contacts 74 and 75 while the key remains in the lock. This feature compels the car driver to withdraw the key from the lock in order to start the engine of the I automobile. When this is done the stop 50 will automatically move away from the recess 57 as already described and 'the spring 40 will be released to move the operating member2Q further toward the left so that the spring 82 may move the contact flange 80 into engagement with the contacts 74 and 7 5. When theoperating member 2O has completed its full movement toward the left, and when the' contact flange 80 has engaged the contacts 7 4 and 75 there will be a slight space between the night hand end of the non-conductz the switch is assured although vthere may bev some slight variations inmanufacture.

'To open lthe switch the oper'ator has but to pushin theqoperating member 20 until the 'l `bolt 41 is "i alignment with the recess 42 whereupon the spring 44' will be released'to maintaln theoperating member innonop erating position andthe switch in open position.' i

One ofl the principal "advantages of the present invention lis that-the opera-tor is required to remove the key from the. lock before the controller can, lbe moved to operating n position"`to 'render operative some essential part of the automobile such as the ignition apparatusx Another feature is that the controller may; b e .moved and locked in'` non-p- `erating positron or the ignition switch in" open position' withouttlie use of a key. Asa result of these.` features ,the likelihood of a car driver leaving the key in the lock whenv nated. i Anotherv feature of the' invention is that the controller .is automatically moved to operating position 'to permit movement` of theswitch'to on position 'when the key i'sref moved from thelock. No further manipulaytion/by.thevoperator is required to render the ignition apparatus -operative while the form Qf embodiment of the presleaving the-car has been. substantially elimientinvention as herein diselosed, constitutes a preferred form, it is to be understood that other forms might be adopted, all coming within the scope of the claims which follow.`
