Ta t/ll whom it may (am-era:

Be it known that I. Lenoir I). KELLoco, a

State of Illinois, have invented certain new and useful Improvements inilgmtion and Lighting Switches, of which the'following is a specification.

My invention rela-tes'to electrical switches and has more particularly to do with combination liphting and ignition switches for' automobi es, such as are generally provided for control b the operator. Tie general object of my invention is to provide a unitary structure including both a lighting and an ignition control switch whichembodies desirable features and advantages all in a simple, compact, eflicient and economical manner. Lighting and ignition switches of the type now commonly used, have two separate actuating members for operating the switches; one for controlling the lighting circuit and the other for controlling theignitionicircuit, and they are generally provided with more or less complicated locking means for. locking the switchesin their different desired positions. A special object of my invention is the provision of a switch of the above type which eliminates this more or less complicated locking mechanism, but

which is so arranged "as to prevent its tion to another un switches from beinp moved from one posiess the operator is provided with the necessaryoperatmg means for performing this function. There are other features of .myinvention which will be more particularly pointed out in the ensuing specification claims.

Referrin now more in general to the de-' I vice as il ustrated, switch S havinfi in positions w lig h it comprises a light a normal and three operatereby three combinations of.

ts may be connected in circuit, the 'referred arrangement being such that w en the light switch is moved to its sition B, the side andrear lights are lig ted, when the'light switch is moved to its position 0, the head and rearlights are lighted, and

when the light switch is moved to its po'sition D, all of the'lights are thrown in.cir-' cuit. It is to be understood-that my invention'is not limited to this particular combination of lights or to the four positions of the ignition circuit interrupted without affecting the position of the lighting switch as will also more fnlly'hcreinafter described in the ensuing specification.

,Wi'th this general understanding of my invention as illustrated, Iwill now describe it more in'detail. A mounting late 1 is provided for carrying a -rotatabe switch supporting member '55 as shown in Fiinia, which membercomprises a shaft 2 w ich carries a pair." 50f insulatingly mounted wipers 3 which are held apart although elec tricallyconnectedby a washer 4 the "said wipers and washerfhcing clamped n'pon theshaft by means of a nut 5 which has screw threaded enfgagementwvith the upper portion 'of the sha I I provide a device for ieldingly holdingthe light switch S in its iflerent operating positions, this device including a notched or serrated disk ,6 which is preferably integral with the' shaft 2, and an arm 24 provided with a roller 25-ior co-operating with the member 6 in a manner to be morefully hereinafter described. To insure that the relation between the disk (i-andwipers 3'rcmains the' shine; a pin 7 is prov ded which is pressed through an insulating bushing in the disks, the pin and bushing then through the wipers 3. The wipers extending are pre erably constructed of two parts 'electricall .umted by the washer 4 as before Iii-" 8! afar-tummy shown "in Fl a, while the mentions the up r wiper comprising 8* an the lower vwiper comapartsli and 3, the upper blades with a common se ent with 'tli e segments'fl 10 and 11 most clearly shown in ig. -9. 'lhe segmerits 9, 10 and '11 areconnected to the terminals 12, 13

' and 14-by means of screws 15, while the cum, ,mon segment 8 connects to. the terminal '16 by means of clam ing screw 17. The light switch S, as a who e, is rotatably supported -.in an annular "orifice 18 in the mounting late 1 and held against. longitudinal motion y means of a nut'19 which has screw threaded engagement with the lower portion ofeth e shaft 2. The segments 9, 10 and 11 are .insulatingly mounted on the plate 1 by means of the screws 15, and the common segment 8 is supported by studs 20, 21 and held in place by means of the insulated clamping screws 17. In Fi 12, I have illustratedthe manner inwhic a se ment as 9, is connectggi to its rear termin' this figureheifi'ga section along line 12,12 of Fig. 4. The segment 9 is insulated from the plate 1 by means of the insulation block 22 and conncted to the terminal 12 by means of the pcrews 15. -'The said terminal 12 is also insulated from the mounting plate L by means ofthe insulation strip 23. With the light switch wipers in their normal msitiou A, there is no effective connection etween .the contact segments of the switch, but when it is moved to the position B, segments 8. 9 and 10 are connectedas indicated in Figs.

8'and 9 giving one combination of lights.

-- Now, if'the light, switch is moved to itsposition C, contact segments 8,10 and 11 areconnected as indicated in Figs. 8 and 9 grvuig a second combination of lights, the segment 9 has its right end position cut ,away so that when the light switch is in position 0 the wipexsrest over so cut 9 ut do, not make contact therewit as is clearlyshown m Fig. 6, if theulie'ht switch art,

switch in any of its'plurality 'of operative positions, 1' provides holding device H comprising an arm 24 carrying a rotatable roller 25' adapted to co-operate with the serrated disk 6, the said arm being pivotally supported at its other end by means of the ,stud 26 carried by the. plate 1." A spring member 27 rests upon the connecting bridge 28 of the arm 2i and this spring presses the roller 25 against the disk 6 so that when -the light switch is operated a tooth of' the notched disk 6 presses against the roller 25 forcing it outwardly against the action of the spring 27, and as the disk advunces,.tl1e

'roller .acts upon-the opposite face of the 'tooth to give a quick snap action to the switch, and thereafter 0 rates to maintain the switch in its operate position.

Referring now to the ignition switch IS, it comprises resilient spring members 30 and 31 insulatiri'glymounted upon a tripod 32 which is fastened tothe. mounting plate 1 in. any suitable manner as by means of the screws 33. Suitable terminals 34 are provided for'the" resilient spring members 30 and 31. I provide a casing 35 in the form of a cylindrical tube for enclosing'the switch appanatus, the said casing 35 also forming the' supporting means forthe mounting plate 1. I The 'plate 1 has a plurality of earsr ifi struek'np at right angles to the face of said plate 1, the said cars 36 aligning with suitable slots 37 cut in theorising 35 so that when the mounting plate 1 is inserted into the easlag-35, the port-ion 36 ofthe cars 36 enter the slots 37 in 'the casing 35. Suitable holes are provided in the ears 36 to receive screws 38 which have screw threaded engagement with tapped and threaded holes 39 in'the casing 35, thus securely holding the lighting and-i nition switches as a unit in the casing 3: cap -16 15 provided for enclosing the lOWQIPOl'tIOH of the swltch structure and is held in place upon the casing 35 by means of screws 52. The cap is also provided with an openmgfitl' through which leads arecxtendcd from the terminals of .the switches. A

front'mounting plateiO is provided which fits over the opposite end of casing 35 and is provided with an integrally formed flange 40 for securing the device as a unit to any desirable mounting member. The'cap 40 is fastened to the gasigg by means of the screws 41, and encloses the upper,por'tion. vof'the f switch as a whole. The cap 4fl salso proyided 1witlala clpllar 43 whosejoentratlfignfics .1 p e x g l in pej .i ,gfe i. a being rotatably mounted in annular'oritigein the ca many suitablfijm' ner,as.i-;inosfi;clearly by spun over the-ooverrofthe andits' other end spun over a w a9, ichhi slinserted between the ca the q-igpun'portion of the collar 43.- oo

an 'actuatin shaft orke -45 which isvtused to operate t e light and also used to control the ignition switch as will be described. i

The actuating plunger 45 is divided into three portions the upper portion 45 being preferably hexagonal in shape co-operating with the collar 43 which is rotatably secured to the cap 40, the central portion 45 being square in sha and co-operating with a rectang'ularori cein the shaft of the light switch while its oppositeend 45 is adapted to co-operate with the ignition springs- 25 and 31. The hexagonal portion 45 of the key 45 has an indicating arrow 47 fastened thereto in any suitable manner as by means of a pin 48, the arrow serving the purpose of indicatin the different operative positions 50 of the lig t switch, namely oil, side and rear, etc, thus enabling the operator to see at a glance which combination of lights is in use. The end of the hexagonal portion of the key is threaded to receive a knob 50 .35 which facilitates the turning of the key to rotate the light switch to its difierent operative positions. The shaft 2 of the light,

switch S has a square orifice extending the length of the said 'shaft one side of which is provided with a bead or rib 51 extending the a length of the opening, the square portion of the key 45 h ving a groove or slot 53' of a size and shape to receive the bead 51 of the square opening of the light switch shaft.

45 The oposite end of the key 45 has an insulating annular button 54 attached to it and next to it a metallic ring 55 suitably insulated from the key, which co-operates with the ignition springs 30 and 31.- v p Referring now to Fig. '3, the key 45 is shown in its operative position, that is, the metallic ring is in contact with the ignitionsprings 30 and 31 thus closin the cir- -cuit of the-ignition apparatus. he light 55 switch is so arran that it may be moved .to any of its p'ositipns without affecting the ignition circuit.

, To move the said-lighting switch S\into any one of its plurality of positions the c athe operator'grasps the knob 50 and rotates "it-Lin the direction to light any particular combination of lights, that is desired. The

. movement of the key 45 rotates the wipers 3 Zinto engagement with the difierent segments fii'to close circuit, arrangements to give the combinationof lights desired. The light Sis' held in its operated position by longitudinally move the key 5 until the portion 54 is brought between the springs 30 and 31. The ignition circuit is thus opened but the light switch S will be held in its position due to the yielding holding device H. Should the operator desire to leave his car stand at any place for any length of time, he disassociates the actuating member or key 45 from its casing by entirely removing it therefrom, thereby opening the ignition switch while permitting the lighb ing switch to remain in any desired position. When the plug is removed the ignition switch is inaccessible to any person other than the one provided with the proper combination key. The lighting switch is also rendered inaccessible to any other than the operator provided with the proper key. The

bead 51 and groove 53 in the shaft 2 and the. portion 451 of the key 45 respectively provide means so that upon the reinsertion of the key the operator will always be able to place the key back into the light switch in the same position as it was at the time of withdrawal, and the arrow will oint. to the combination that is lighted. hen the key is inserted into the collar 43, the'operator rotates the key, due to the rdtatable collar 43 until the groove 53 in the poition 45 of the key 45 coincides with the head 51 in the shaft 2 of the light syvitch and when the key is in 10 this position it may be further :longitudi nally operated to bring the portion 54 of the key into operative relation with the springs 30 and 31. The grooves in the members 54 and 55 co-operate with the rounded end portion of the s rings 30 and 31 to provide means for yie dingly holding the actuating member a ainst longitudinal movement, thereby holding the ignition switch in its on or of! position.

From the above it may be seen that the lights of the car may remain in circuit and at i the same time the circuit of the ignition apparatus may be opened and the actuating members disassociated from the rest of the switch so as to prevent tampering with the same. \Vith my improved switch, I do away with many compilicated parts, this producing a-switch simple in construcilon and most efiicient as a lighting and ignitionj 13o switch, cheap in its construction and at the same time a positive lock against operation by other than the operator. It is of course understood that many different sizes and shaped actuating members may be used thereby giving an infinite number of combinations without departing from the scope of my invention; It is also apparent that the actuating member may be provided with a greater number of irregularly shaped sections for co-o ration with an equal number of similarly slizped apertures respectively.

In illustrating my invention I have chosen a preferred form but it is to be understood that many chan es and modifications will readily suggest t emselves, and I therefore do not desire to be limited to the exact structure as shown but aim to cover all such changes and modifications as come within the spirit and scope of the appended claims.
