SWITCH.v

'i i Application filed May 6, 1922. Serial No. 558,852.

This invention relates to lighting and ignition switches for automobiles and has among its objects the provision of a switch which is relatively compact and small in dimensionsfbut which ycan be used to con trol a relatively large number of lighting circuits as well as to control the ignition.A

In carrying out this aim of the invention, it is a further object to provide the maximum number of positions for the light switch lever, and to provide a plurality of oi positions for the ignition switch lever, in'order that the ignition lever may be used to con-y trol certainlighting circuits.

Further objects and advantages ot the present invention will he apparent from the following description, reference being had to the .accompanying drawings,- wherein a pre erred embodiment of the present invention is clearly shown. Y

In the drawings:

F ig. 5 is an inside view, the switch back 'The diai ai bears ail-ee indicia. Ignition, OllandCurbvto indicate the positions of the ignition switch handle 26; and also indicia Oil, Courtesy, Bright. Dim and All to indi- Y cate the p positions of the lighting switch handle 27. i, p Handle 26.includes a barrel or hub carrying contact 28 having lingers 29, 30 and 31, also carrying a ratchet pli-ate 32v havin-g a notch 33. Handle 27 includes a similar bar'- rel or hub 34 (Fig. 4) carrying acontact 35 having ngers 36, 37, 38, 39 and 40, also carrying a ratchet plate 41.` The construction of these handles and the parts carried thereby is described and claimed in the copending application Serial No. 481,138. A spring pressed ball 42 cooperates with each ratchet shown in Fig. 10) to :yieldingly maintain the switch handles lin their difterent positions. Each handle extends through one of the terrule's 25 (Fig. 4).

,s A lock of the Yale type comprises a lock housing having lugs 51 by means of Which the housing is mounted upon the switch housing 20 Irising screws 52. Within housing 50 is a rotatable key operated `barrel 53 which projects through ferrule 24. Barrel 53 carries .discr54 having segment 55 adapted to Contact with pin 56 carried by plate vfwhich is loosely mounted concentricwith disc 54. Plate 57 has lugs 58 and 59 adapted to engage a lug; 60 carried by locking bolt 61 which is slidably mounted upon guides 62 and 63 provided in housing 20. A screw 64 threaded into hole 65 in housing 20 assists in holding bolt luponthe guidesf The lock housing 50 extends through the opening 66 in bolt 61, and also a stop pin ,67 against which the lug 58 may strike (Fig. `5). Pin 67 is carried by lock housing l50. Bolt 61 is providedwith lug 70 adapt-ed to be moved into the notch 33 of ratchet'plate 32 when the lock barrel 53 is turned clockwise as viewed in Fig. 5. Therefore. when the bolt .61 is in locked position, the handle 26 cannot be moved into Ignition position (meaning ignition On). but the handle 26 can be moved from Off to Curbposition (meaning curb or parking light On).

' is concentric with the switch contact 32.

Contact 93 is connected with battery terminal post 96, contact 89with courtesyY light terminalpost 97, contact 87 with` tail light terminal postl 98, contact 85 with dim light terminal post 99, contact 84 with strip` 100 and head light terminal post 101, contacts-82 and 90 with strip 102 and curb light terminal post 103, and contact 91 with ignition terminal post 104. y Strip 105 connects contacts v86and 87 with contact 92. Strip 106 connects contacts 93, 941 and 95 with contacts 88 and 88a.

` :When the levers 26 and 27 are in the po-v sition shown in Fig. 1, and the contacts l32 and 35 in the position shown in Fig. 3, the battery terminal 96 will not be connected with any of the work circuits such as the ignition and lighting. circuits indicated on Fig. 3. It the lever 26 be moved clockwise to ignition position as shown in Fig. 1, then the Contact 32 will be moved counterclockwise as viewed in Fig. 3, and the contact linger 31 .will engage the contact 96 and the Contact linger 30 will engage the contact 91 thus connecting the battery with the ignition circuit. It the lever 26 be moved counterclockwise into curb position shown in Fig. 1 then the Contact 32 will be moved clockwise so that the contact linger 31 will engage the contact 95 and the contact 29 will engage thev contact-90 and so that the contact l klinger 30 will engage the contact 92. In this manner the battery terminal 96 will be connected with curb light terminal 103 and with the tail light terminal 98.` Thus. it is Vapparent that the ignition lever 26 may be utilized when not in use for making an ignition circuit connection, in establishinga connection from the battery tothe parkingV lights whichl are provided for by curb lights and a tail light. rihis feature olz the invention is advantageous since the one lever can be used not only as an ignition switch lever vbut also asa light switch lever for control- It isfapparent from the drawings that the lever 27 can have but live positions, Where the proportions shown are maintained. It is of course tobe understood that it the dimensions oi' the switch were enlarged or the contacts made smaller it would be possible'to provide more circuit controlling positions for the lever 27. But, whatever may be the dimensions of the switch and the relative proportions of its parts, the utilization of the ignition switch lever as a lighting switch lever will increase the capacity of the switch since it is possible'to add more circuit controlling positions 'lor the lighting switch lever than would otherwise be possible.y

Counterclockwise rotation of lever 27 into Courtesy, position results in clockwise movement ot contact 35 as viewed in Fig. 3 wherein the linger 36 will engage contact 85, linger 38 will engage contact 87 and finger l0 will engage contact 89, and contact finger 39 will engage contact 88a. In this manner the battery terminal 96 will be connected with the courtesy circuit terminal post 97, wi thtail light terminal post 98 and with dim light terminal post 9, y f

Movement' of lever 27 into Bright position will cause the contact 35 to be moved clockwise so that` linger .t0 is olif contact, linger 39 is on cont-act 88, linger 38 is on contact 86,-linger 37 is ott contact and linger 36 is on contactf84. In this manner battery terminal post 96 will be connected with tail light terminal post 98 and with head lamp terminal post 101.

Movement ol the lever 27 into Dim position will cause the contact v35 to be moved clockwise as viewed in Fig. 3 until the nfer 4:0 contacts with contact 88a, linger 39 with contact 87, linger 38 with no contact, finger 37 with contact 85, and contact linger 36 with contact 83 whichis not connected with any circuit. The 4battery terminal post 96 will therefore be connected with tail lamp terminal post 98 and with dim light terminal post 99.

lVlien the lever 27 has been moved into All position each linger of contact 35 will be moved clockwise tour spaces or so that contact 40 touches contact 88, contact 39 touches contact 86, Contact 35 touches contact 84, and contact 36 touches contact 82. Therefore the battery terminal post will be connected with tail lamp terminal post'98 with head lamp terminal post 101 and with curb lamp terminal post 103. y Itis apparent from the foregoing that there has been provided a lighting and ignition switch which is relatively very compact in construction and small in dimensions and is capable of providing an ignition circuit connection and live dilierent lighting circuits. A lock has been provided to lock the ignition lover in otl' positions, that is, to prevent this lever from being moved into ignition circuit making position. However both the ignition lever and the lighting switch lever may be moved to select any one ot the lighting circuits while the ignition is locke 'y iVhile the form of mechanism herein shown and described constitutes a preferred form of embodiments olf the invention, it

is to be understood that other forms might be adopted, all coming Within the scope of the claim Which follows.

I Claim: y

In an automobile, in combination, an electrie switch having a battery circuit terminal, an ignition circuit terminal and a parking light circuit terminal, and a look controlled switch member movable when in unlocked oonditionoto connect ythe battery terminal With either the ignition terminal or parking light terminal or to 0E position, and movable Wheninlockedconclition to connect the battery terminal only With the parking light terminal or'to oli' position.
