To all wjzom it may concern:

Be it known that I, FRANK A. Znra, a. subject of Austria-I'Iungary, and IQSlClGlllfOf Chicago,in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Systems of Electr cal Distribution, (Case 1),) of which the fol lowing is a full, clear, and exact spec1heation.

My invention relates to improvements in high potential circuits for the electric spark producing means for internal combustion engines and means for controlling said oncuits.

One of the objects of my invention is to provide means for controlling the high potential circuits coming from two sources of current supply for a dual set of spark plugs for each of the cylinders of an internal coinbustion engine, whereby either source of can rent supply may instantly be connected to either set of spark plugs or both sources of current supply may be connected to the re spective set of spark plugs by a simple and easily operable switch and whereby all wires and connections for the entire number of spark plugs may immediately and simultaneously be removed, in a self contained structure, from said plugs.

Another object of my invention is to-pro- Vide a housing or protecting cover for the spark plugs, comprising an integral. structare, such as a continuous tube adapted to Fig. 2 is a longitudinal section taken on line -2 of Fig. 1. Fig. 3 is a section taken on line 3 3 of Fig. 2. Fig. 4 1s a transverse section taken on line H of Fig. 1. Fig. 5 is a central sectional view of the switch mechanism. Fig. 6 is a transverse section taken through the switch on line 6-6 looking in the direction of the arrows. Fig. 7 is a similar section taken on line 7-7 of Fig. 5; looking in the direction of the arrows.

with a metal cap 28, containing Fig. 8 is a similar section taken on line 8-8 of Fig. 5, looking in the direction of the arrows, and Fig. 9 is a top plan view of the re movable member or cover of a switch, and Fig. 10 is an enlarged detail section taken on the line 10--l0 of Fig. 1.

In all the views the same reference charactors are employed to indicate similar parts.

15 is an engine of the ordinary type, 16 is a fly wheel, 17, l8, l9 and 20 are the respective cylinders of the engine, 21 is the magneto for supplying high tension current for the purpose of producing sparks within the cylinder of the engine and affording one source of current supply, and 22 is a battery affording another source of current supply. 23 is the induction coil casing, which also contains a switch operable by the handle 2%. 25 is the usual current distributor and 26 is the vertical shaft rotatable for the purpose of operating the distributer as usual in such structures. So far I have described the parts common-to engines of this type. Each of the cylinders is provided with two spark plugs. One of the series for each engine I have indicated by the letter A and the other series I have indicated by letter B. A tube 27 of suitable material, may be of hard rubher or the like, extends hmgitudinally of the cylinders and is provided on each of its ends a clip 29, and a set screw 30. A rod 3]. is secured to the end cylinder, 17 and 20, as by bolts32, the upper ends of the rods extend above the cylinders and are adapted to enter the clips 29-29, the tube 27 is adjustable on said rods and is secured. in position by means ,of the clamp screws 3030. The tube 27 is perforated at intervals as at a=b for insertion of the respective spark plugs A and B. A partition 34, of insulating material, extends longitudinally of the tube and is secured in substantially diainctric position by means of pins The partition 34: may be centrally perforated as at 36, or divided into two parts for admission of the wires that are to be connected to the plugs a and 7), re spectively, that are screwed into the partition support and are located in such position as to register with the perforations a and Z) in the outer tube 27. The plugs a and I) each have connected on their lower ends a spring clip 38 which is secured thereto by means of a screw 39. The clip 38 yieldingl engages a contact 40 carried by the upper Patented Mar. 30, 1915.

end of the spark plugs A and :6. Wires a, a, a and a connect the respective plugs A that are supported in the partition 34c with the magneto ill, and wires 6, b, I), connect the respective plugs B with wires leading from the secondary of the induc tio'n coils contained in the casing Other wires m m m and m lead from the magneto 21 to a suitable switch containedin the casing 23. Wires al (P, d and at connect the said switch with the distributer 25, and wires 22- and 22 connect the storage battery 22 with (the primary oi the induction coils contained within the casing; 23. By this means the spark plugs A of the

respective cylinders

17, 18, 19 and 20, may be energized-by sparks coming from the magneto 21 and. spark plugs designated by the letter B may be energized by current coming from the induction coils, located within the casing 23. These wires are contained for purpose of convenience, within fixed protecting pipes 411, 42, and Pipe 43 terminates in a switch. set. These pipes are fixed to the engine structure by clips 415, or otherwise. The lower member, l6 oi the switch 44, is secured tothe upper end of the pipe 43, and the up gier or top member 4:7 of the switch, is secli red to a pipe 48, which is secured to the protecting pipe or tube 27, as-at 49. The arrangement is such that when the tube or pipe 2? is removed the pipe 48 the upper cap member 4.5 of the switch is, as Wiili'RS the wires connecting these instrumentaiities may be bodily removed with the tube.

The switch 4% is preferably made of hard rubber and contains five major parts. the.

base L6, the cap 47, aindtbe cup part 50, which contains a. movable ring 51, and an internal rotatable dist: The latter rotates upon a central stem The ring 51, is adapted to be slightly oscillated by means of the radially extending handle 51, which is secured thereto, and the disk 52 is adapt ed. to be. slightly oscillated by the radially disposed handle 55, which is secured to the said disk. These parts are limited in their movements in slots 56 and 57 respectively, which are made in the side walls of the cup shaped member 50. The ring; 51 carries con tact pins A A, ii and A which are adapted to complete the circuit for the spark plugs indicated by the. letter A. and the dislc 52 carries similar pins designated by the letters ll, 13, B and l3 which are adapted to complete the electric circuits for the 'spective spark plugs B. These pins are circurnferentially elongated on t under side "of: the disk as at A, A A i i-i' as t maintain electric circuit with the resueettve pins immediately underlving the ring. fit, when the said rings are ightly oscii a and the disk 52 is pro ided with similar elcngations B", B B and .5?)

, respectively.

The cup shaped member 50 contains similar contact pins without extensions which I have indicated by the same reference numerals A A, A", and A and B B B and B", respectively.

The cover or top member 47, shown reduced in size in Fig. 9, is provided with 16 perforations and an equal number of contacting pins, four of which pins I have des ignated by reference characters A A, A and A and the other complementary pins 1 have designated by reference characters A, A, A and A. The other set of pins I have designated by the reference characters B B B and B and'the complemem tary pins by 13 B, B and B A and B are connected togdtherby a crossipiece and from this cross piece the wire a" is connected, and this 'wire communicates with the spark plug A of cylinder 17, and in like manner the respective connections for the other pins are made on top of the cover, as clearly indicated in Fig. 9.

A switch lever 60 is pivoted, as at 61, and is connected at its ends by rods 62 and 63, respectively. The rod 63 is pivotally co nected with the switch lever- 54 which oscil lates the disk 52 and the rod 62 isconnected with the lever 55 which oscillates the ring 5]., so that when pressure is applied to either end of the switch lever 60, as in theoperation of a push button switch, the levers 54 and will be respectively oscillated, one will be moved ahead and the other lever will be moved in a rearward direction. Nowit is evident that if the disk 52 be rotatedsli 'htly' in one direction, by means of the push button switch referred to, that the current will 7 be communicated from the magneto to the series of spark plugs A, for instance, and it the ring 51 be at the same time slightly oscillated in the opposite direction, current- Will be carried from the induction coils, energized by the storage battery, to the series of spark plugs 13 and if the ring and disk be oscillated in the opposite direction, as by pressure upon the other end of the switch.

lever 80, the respective spark plugs will be ener zed from the other source oi: electric Q energy so that by merely pressing on one or the other end of the switch lever 60 the series of spark plugs may be energized by either source of electric energy, the battery or the magneto, or from both sources of energy, or by pressing the switch lever only slightly in one direction or the other, either over one Wire from the magneto to a spark,

plug, and from the v spark plug -to a mnded to the framebf llltl engine, the

messes g ground on the engine frame and from that ground to the rotating member of the distributer 25 and through the wire selected by the distributor d d d and d, as the case may be, back to the magneto, over one of the wires m m m, or m*, and in this manner the clrcuit may also be closed and traced from the secondary windings of the inductioncoils contained within the casing 38, throughany one of the respective spark plugs. 1

. As the tube27, and the tube 48 are-secured together and contain the wires necessary for completing the circuits to the spark plugs, and as the tube 48 is also secured to the bodily removable cap member 47, of the switch, "it is only necessary to loosen the thumb screws '30 from the stems or rods 31-31 in order that the conductors contained within the tubes 27 and 48 may be entirely taken away and the spark plugs examined, removed or changed, and when necessary a new structure of the same character may re place the one removed; I

While I have herein shown a single embodiment of my invention and certain arbitrary arrangement of circuits for the purpose of clear disclosure, it is manifest that changes may be made both in the arrangement of the circuits and the character of the parts, without departing from the spirit of my invention or the scope of the appended claims.
