,n si mfp@ admini, a cui Application filed March 18, 1911.v Serial No. 614,764.

T0 @ZZ evito/m, if may concern Re it l" f ivn that I, HENRY G. COX, a citizen ci the nited States, residing at Detroit, in the county et llfayne and State of Michigan, have invented a new and useful Mag netovliattery Switch, of which the following is a speciiication.

In the operation of internal combustion engines, especially of the type commonly in use in automobiles` the ignition is accomplished by means 'ot electric sparks produced either troni a battery or a magneto. generator, and the object of my invent-ion is to produce a switch of such form that it may be readily and accurately operated by toot in such manner that either battery or magneto may be connected with or discon-v nected trom the distributing circuit and also of such character that, When in battery con necting position, slight additional pressure will bring into operation a vibrator .which will operate to produce a continuous stream of sparks Within that particular engine cylinder connected by the distributer with the The accompanying drawings illustrate invention.

Figure 1 is a front. elevation of one torm ot the improved switch, With the cover plate removed, and with a Wiring diagram; Fig. 2

a section on line 2-2 oit' Fig. 1 Fig. 3 asection on line 3 3` of Fig. 1; Fig. 4 a front ele-v vation of the apparatus with the cover in place; andFig. 5 a sectional vieW'ot a detail. In the drawings, 10 indicates a cup-like .base preferably formed of insulating material and conveniently triangular in shape. Rising from the bottom of base 10 are three pins 11, 12 and 13, each of vvhich is provided with a semi-spherical enlargement 14 at its base' The three pins 11, 12 and 13 are arranged at the middles of the sides 'of the base 10 and sleeved over said pins is a triangular metal sivitch trame 15, each side of which is perforated, as indicated 'at 1G, to receive one ot the pins. Each of the perforations 16 has a semi-spherical scat at its inner end to receive one ot the enlargements 14, the construction being such that the trame 15 may be readily rocked in any one of three directions upon anypair of pins. Carried at the apices ot' trame 15 are push buttons 17, 18 and 19 which project trom the trame 15 preferably through a suitable coverplate 21. rThe frame 15 is preferably open in its center in order to givel space for the Patented July 39, 11912.

4.18, is a linger 31 Whichfis a aptedto cooperate with a terminal '32'. Projecting from that apex of frame 15 which carries button19 is a finger 33 arranged to cooperate with a retainer 34. The terminals 29 and 32 and retainer 34 may be like ter# minals 28. Projecting from the apeX Which carries' the push button 18is an arm 35 adapted to engage an insulating button 36 Acarried by a spring terminal 37 secured in the bottom of the base 10, and this terminal 37 is adapted, when suiiiciently depressed, to'

contact with a terminal 38.

In order that the device may be readily rendered inactive I mount the push button 19 removably and rotatably in the frame 15, and provide said button With a projecting key 41 which may be irst introduced into slot L12in trame 15 and then turned into slot 43- of said frame so as to drive a spring termmal 111i, attached to, and in electrical contact with, frame 15, into contact with a terminal 4:5 mounted in the cup 10. In use, y

this con'tactI being maintained in all ,positions of trame 15, the apparatus Will'be set in front of the operator, either upon the floor or upon the dash board of the car in such position that the operator may engage any one of the push buttons 17, 18 or 19 and operate the same by a direct leg push. I prefer .to mount the apparatus substantiallyvertically on the dashboard with the button 19 uppermost. The followingwiring connections are then made z-From one side of battery 51 by a Wire 52 .to terminalv 32 and1 from the other side of battery 51 by Wire 58 to terminal'28; Wire 54 from terminal 28 to terminal 23; wire 55 from terminalQt-` to one end` of the coil of the vibrator 22, and Wire 56 rem'the other end ot said coil to terminal 37 Wire- 57 from wire '58 (or termina 28) to the insulated` terminal 58 otA the u ual interrupt'er 59 car ried by the magneto 51'; by Wire 62 from the ungrounded terminal 63 of the magneto to terminal 29; wire (54- trom the terminal G5 of the spari; coilGt tothe `grounded lterminal 57 oit the magneto; wirel (3S from terminal. 33 to termi ual (35, and wire (Si) trom the primary terminal 71 of the spark coil 6G to tern'iinal a5.

rThe operation is as follows; An inscrtion ot the button 19 into its proper place in iframe 15 to the position shown in 1, will serre to bring` into contact the terminals l-ll and 115, thus putting the trame 15 into the primary circuit. A pressure upon-the button 19 will cause the frame 15 to swing upon pins 11 and 13 as a tulcrum so as to drive finger 33 into the i.'etaininf l engagement ot the member 34 so as to hold traine 15 in its neutral position. In this position of trame 15 both thebattery and magneto circuits are broken. By exerting` a pressure upon button 1S, trame 15 will swing` upon pins 12 and 13 as a i'ulcrum so as to withdraw finger 33- from retainer 34e and drive finger 31 down into engagement with terminals 32 where it will be yieldingly 4retained so as to complete the battery circuit 51, 52, 32, 31, 15, M, 15, 69,721,135, G11, 67, 58, 57, 53. lf a starting' spark is desired the operator will. press hard enough upon button 18 to drive the spring terminal 37 into vContact with terminal 38, whereupon a 'circuity will be established trom battery 51 through 53, 23, 5st, 23, 25, 24, 55, 22, 56, 37, 38, 68,65, 71, 69, 45, fist, 15, 31, 32 and 52 so that by reason of the action oit the vibrator 22, a rapid succession of sparks will be automatically produced in whichever cylinder is in proper condition to receive a spark Ytrom the secondary'circuit 81. As soon as the engine is started, the additional pressure upon frame 15 will be withdrawn so as to permit terminal 37 to withdraw from terminal 38, and the movement of the engine will rotate the magneto 'and interrupter. Thereafter so long 'as the trame 15 remains in the position indicated, the sparking-circuit will be as previously described.

Whenever the magneto has reached a desired and proper generating speed, the operator will then press upon button 17 so as to swing frame 15 upon pins 11 and 12v thereby withdrawing ingg'cr 31 from terminal 32 and projecting fingers 26 and 27 into contact with terminals 28 and 29, respectively, whereupon the following circuits will be established: (1) Art the times when the points in the interrupter box are in engagement the circuit will be, 63, 62, 29, 27 15, 26,23,57,58,generator (2) At the times when the points in the interruptor box are not in engagement the circuit will be, 63, 62, 27, 15, 111,115,69, 71, 65, 64,57, generator, 6. V E

.lt is desirable at times to be able' to deinsegne liver a stream of sparks to the engine while the operator is in 'front orn the machine cranling it and igor that purpose, I provide a push button 91 which is mounted in the main body 10. This push button is normally urged outvardly by a spring 92 and at its inner end carries a spring terminal 93 which, at its tip is formed into a catch 93 adapted to coperate with a terminal. 91- which is secured to and in electrical contact with terminal The terminal 93 is connected by a. wire D5 with wire G3 and at its inner end is provided with a tip which, when frame 15 lis depressed by operation upon button 1S, will overlic the trame, clearly indicated in Figi. The terminals 93, 3l thus form a parallel around the two terminals 37, 38, when terminals 93, 91- are in contact and the same insults may then be attained as may be attained by a sulticient pressure upon lmtton 1S to bring` terminal 37 into contact with terminal 38. ltfhen pressure is applied to button 17, however, frame 15 will 'engage the tip 93 ot tcrminal 93, 'aise it from engagement behind terminal 94, and spring will serve to drive the terminal 93 away from terminal 94. 1
