Figs. 6,7 and 8 are sectional viewstaken .respectively v.on the lines fi- 6. 77 and `8`8ofFig.`5. i Fig. v9 is a sectional viewfon the line 9-9 i of Fig; 8. b i i Referring to Figs. Vl and 2, 2O designates an.internal.combustionvengine located be-` `50 tween a radiator 21 and a partition orrdashboard 22 which together with hood parts 23 i and 24, hinged at 25, provide an enclosure for thev engine, an ,1gn1t1on tuner 26 con- Y nectedtherewith, `an ignition coil 27 ,1 and an ignition switch 28. A wire 29 connects the highA tension winding Vof the coil 27` with a center terminal of a distributorcap 30. Al wire 311connectsa primary ter1ninal132 of the coil 27 with the insulated terminal 33 of the timer 26. 1 A wire 34 connects the;
terminal of the v,coil 27 with a terminal 36 ofthe switch 28. The other switch terminal 37 is connected with a'batteryorother current source 38 shown Vdiagrammatically in Fig. 2.` By mechanism `.within the switch:
`The switch 28 comprises a cup-shaped case 40 havinga tubularjshank 4l which extends through a suitable opening in the partition wall .22. The case 4()` is provided with aper- .tured `ears-42 Afor receiving bolts 43vwhich attach the case to the wall 22 as shown in Fig. 2.` The tubular shank 41 provides am;
`bearing 44'for a switch operating shaft 45 which isprovidedk with a flange 46 notched` at v47 to provide stops 48 and 49 which cooperate with a pin `50 attached to the case `40 in order to limit rotation ofthe shaft 45.1,
The flange 46 carries a pin ,or stud 51 fwhich is received by a suitable notch in a plate A52 (see Fig. 6) mounted upon the shaft 45 and drivingly connected therewith by the pin `51. The plate 52 is provided with lugs 53l which. are received byy suitable notches in a plate 54 in order to support the plate 54 and drivingly connect it with the plate 52. i The p1ate54 isconnected with a nonconducting plate 55 bythe shank 56 of astud57. The stud .57 isfcoaxial with the shaft V45 and extends through suitable holes in the plates 55 andI 54, these plates beinglocated between a shoulder 58 of the ,stud 57 and the rivetedover endV 59 of -the stud. The plate 55 is also drivingly connected withthe plate 52 by providing it with notches for receiving thelugs 53. Y
The plate 55 carries rivets 60 having flat heads 61 received by countersunk apertures.
in the plate and bearing against the plate 54 in order to limit axial movement of the rivets relative to the plate 55. The rivets 60 have round heads 62 which are spaced from the plate 55. The shanks of the rivets 60 pass through suitable holes in a metal disc 63 which is formed of sheet metal thinner than the space between the head 62 of each rivet 60 and the plate 55. Thus, the met-al disc 63 is drivingly connected with the plate 55 and hence with the shaft 45 and is free to move axially of the shaft to a limited eX- tent. The disc 63 is provided with a central aperture to provide clearance for the shoulder 58 of the stud 57. The disc 63 is provided with spherical projections 64 urged by springs 640J into engagement with stationary switch contacts 65 (see Fig. 6) provided by the switch terminals 36 and 37 which are preferably in the form of tubular rivets for securing a non-conducting block 66 to a metal cover 67. Screws 71 engaging tapped holes 72 in the case 40 secure the cover 67 to the case. Each of the terminal members 36 and 37 is threaded internally for receiving a wire securing screw and is insulated from the cover 67 by insulating washers 68 and 69. The block 66 is provided with a hole 70 which is in alignment with the shaft 45 when the cover 67 is attached to the case 40. The hole in the block 66 receives the stud 57 and therefore the plates 54 and 55 are held in alignment with the shaft 45.
The case 40 is provided with tubular estensions each .divided by longitudinal slots 81 to provide portions which may be clamped around one end of a Bowden wire tube 82. A clamping band 83 cooperates with a bolt 84 and a nut 85 to squeeze the two parts of the tubular extension 80 against the Bowden wire tube 82. The other ends of the Bowden wire tube 82 are attached to blocks 86 which are fastened to the automobile frame inside of the hood. Each tube 82 encloses a Bowden wire 87 having one end attached to a locking bolt 88 adapted to pass through a hole 89 in a lug 90 which is attached to the hood on the inside thereof. The Bowden wires 87 extend through the tubular extensions 80 and within the ca se 40 and each wire 87 passes through a stud 9.1 which is pivotally supported by the plate 52. Each wire 87 is clamped to the stud 91 by a set screw 92 which is threaded into a tapped hole in the stud and which engages that portion of the wire which extends across the threaded hole. Each stud 91 has a portion 93 reduced in diameter to form a journal within the plate 52 for the stud 91. The portion 93 is slightly greater in width .than the thickness of the platev52. Each stud is retained bv riveting it to a washer 94.
A tube 100 extends from the tubular shank 41 of the switch case 40 and receives one end of a key barrel 101 which is attached in any suitable manner to a supporting plate 102 which may be the instrument board of the automobile. When the proper key 103 is inserted in the lock, a lock shaft 104 may be rotated by the key. Rotary motion is transmitted from the lock shaft 104 to the switch shaft 45 by a rod 105 attached at one end to the shaft 104 and provided at its other end with a pin 106 which extends into longitudinal slots 107 provided by the shaft 45. lVhen the switch contact member 63 is in the position shown in the drawings, the ignition circuit will be interrupted and the locking bolts 88 will be extended through the lugs 90 which are attached to the hood members 23 and 24. In this way the ignition circuit is rendered inoperative and the ignition apparatus is locked within a case provided by the hood members 23 and 24 so that the ignition apparatus cannot be tampered with or the switch terminals 36 and 37 connected outside of the switch. When the switch contact members 64 are turned so as to engage the inner ends of the terminal rivets 36 and 37, thc locking bolts 88 will be withdrawn from thc lugs and the ignition circuit will be closed so that the engine may be supplied with ignition.
The device is constructed so that either the lock or the switch may be removed from its support without disturbing the other` and so that parts of the switch may be removed from the switch case while the latter remains attached to its support. The Bowden wires and Bowden wire tubes may be removedV while the switch case remains attached to its support.
The lock barrel 101, which is provided with flats 110, is received hy a hole in the metal instrument panel 102 having corre' sponding flats 111. A nut 112 cooperates with the interrupted screw-threaded portions 113 of the barrel 101 to clamp the panel 102 between the nut 112 and a shoulder 114 of the barrel 101. To make difficult the removal of the barrel 101, there is provided a washer 115 having a central hole the same shape as the hole provided in the panel for the lock barrel. and having ears 116. The washer is located between the nut 112 and the panel 102 and. after the nut 112 is tightened. the ears 116 are bent against the Hats ofthe nut to prevent turning the nut. It would require a thief with special tools a considerable period of time to remove the lock barrel so that the switch could be manipulated. After the nut has been removed the lock barrel and connecting shaft 105 can be removed bv passing them through the panel 102 while the switch 28 remains assembled with the dash 22. The
tube is of hard metal and is loosely mounted upon the shank 41 of the switch case and upon the lock barrel 101. The tube 100 prevents the use of a pipe wrench upon the shaft to turn it.
The switch 28 may be removed from the dash 22 provided the switch is unlocked so that the hood may be raised. The carriage bolts 43 which are used to attach the case 40 to the dash 22 have their threaded ends located on the engine Yside of the dash when they cooperate with nuts 43a to secure the case to the dash, and have their heads Hush with the drivers side ofthe dash so that the bolts cannot be turned to permit removal of the switch without raising the hood. After the nuts 43a have been removed, the switch 28 may be removed fromthe dash without disturbing the lock.
After removing the switch case cover 67,
loosening the screws 92 which attach theV Bowden wires 87 to the plate 52, and loosening the nuts 85, the wires 87 and the tube S2 may be removed without removing the switch case Al0 from the dash 22.
By providing for the removability of certain parts without disturbing other parts, the maintenance of the device in service is greatly facilitated.
