IGNITION SYSTEM.

Specification of Letters Patent.

Patented Jan. 5, 1915.

Application filed August 25, 1911. Serial No-646,000.

To all whom it may concern:

Be it known that 1, PAUL R. WERNER, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Ignition System, of which the following is a specification.

My present invention relates to an ignition system which is adapted to be used with one transformer and wherein the secondary or high potential current is directed to the proper cylinders in consecutive order by use of a rotating switch or selector, the primary current being produced by the proper action of the contact points.

' In a prior patent granted to me on November 17th, 1909, No. 940,376, I have shown and broadly claimed an ignition system which operates in the manner above referred to and in my present invention I have devised a novel construction of ignition system wherein the primary circuit is made and broken in such a manner that the contact will always be performed at the same time regardless of the engine speed.

My invention further consists of a novel construction of a contact mechanism.

It further consists of a novel construction of short circuiting mechanism whereby any or all of the cylinders may be readily short circuited when desired.

It further consists of a novel and simplitied constrfiction of contact mechanism wherein the number of parts employed are reduced to a minimum and wherein the device may be readily removed or taken apart without the necessity of employing any tools.

It further consists of novel means for ad vancing or retarding the spark.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustrating my invention, I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described;

Figure 1 represents a sectional elevation,

on a reduced scale, of an ignition system embodying my invention, the wiring being omitted. Fig. 2 represents a perspective view of the upperportion of the same having the cover removed and showing more clearly certain parts of the contact mechanism. Fig. 3 represents a sectional plan view of Fig. 2. Fig. 4 represents a top plan view of a portion of'the device having the cover removed. Fig. 5 represents a side elevation of a portion of the short circuit- Ing mechanism. Fig. 6 represents a sectional plan View showing a portion of the contact mechanism the parts being shown in different relation from that seen in Fig. 3.

Fig. 7 represents a perspective view of another portion of the short circuiting mechanism. Fig. 8 represents a perspective view of a portion of the contact mechanism. Fig. 9 represents a sectional plan view similar to Fig. 6 but showing the parts in different relation from that seen in said figure. Fig. 10 represents a side elevation of a portionof the contact mechanism.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings :1 designates a casing provided with a suitable support 2 and a cover 3 which latter is secured thereto in any desired manner.

4 designates a casing member in which is journaled a housing 5, said housing having journaled therein a shaft 6 which is operatively connected withtheengine shaft and provided with a gear 7 meshing with a gear 8 rotatably mounted in the housing 5.

9 designates a gear meshing with the gear 8 and mounted on a shaft 10 journaled in the housing 5 and also in a bracket 11 suitably carried by the casing.

12 designates an arm secured to the housing 5 and adapted to be connected with any suitable mechanism for controlling the revolution of the housing.

The shaft 10 has mounted thereon the selector 13 adapted to engage with the con tacts 14' for the different cylinders, it being evident that any desired number of cylinders may be emploved.

In order to provide means for short circuiting any or all of the cylinders I provide spring members 15 which are suitably aper-' tured as at 16 thereby adapting them tobe carried by the insulation of the contacts 14. Each member 15 is provided with one or more resilient arms 17 which are deflected otherwise adapted to receive thepcontactto coact with a recess 43 in a to form a recess or seat 18 for the journals 19 of the members 20 which latter are defiected so that they are normally held out of engagement with the contacts 14. I

21 designates an extension adapted to engage the casing 1 at certain times.

22 designates pins seated in recesses 23 and having enlarged heads 24 adapted to engage the short circuiting members 20 to actuate the same, the construction of the parts being such that they are normally maintained in'the position indicated at the left hand side .of Fig. 1.

25 designates a primary terminal which has a connection 26 leading to the post 27.

28 designates the secondary terminal which is an electrical coimection with the selector 13.

The top .3 is provided with a boss 29 forming a journal for the shaft 10 which latter extends therethrough and at its outer end is recessed as indicated at 30 thereby forming shoulders 31. The number of such shoulders preferably corresponds to the number of cylinders employed. 32 designates aplate connected with the post 27 andalso'with the post 33 which latter is split or member 34 which is adjustable therein and forms the stationary contact.

35 designates a pivot pin or its equivalent suitably carried by the top 3 and provided with an enlarged heagl 36.

37 designates a movable member which preferably consists of a strip of materialwhich is deflected as indicated at 38 to form a semicircular recess thereby adapting the same to be fulcrumed on the pivot 35. The rear end of the strip 37 is laterally and forwardly deflected as indicated at 39 and the forwardly extending portion is provided with an aperture 40 through which passes a pin 41 the inner end of which is upset or headed to prevent its disengagement from the aperture 40. The opposite end of the pin is provided with a head 42 the outer face of which is rounded or otherwise adapted pin 44 carried by the top 3.

45 designates a spring intermediate the head 43 and a washer 46 loosely mounted on the pin 41 whereby the movable member 37 is held in'proper relation with respect to its fulcrum 35.

47 designates a resilient member one end of which is fixed to the strip 37 while the opposite end thereof has its movement limited by a hook 48 carried by the strip 37 it being noted that the resilient member 47 carries the movable contact 49.

' 50 designates a strip of material forming a movable-member and deflector to provide a recess '51, the rear endof such member being outwardly and forwardly deflected as indicated at 52 and provided with anaperture 53 through which passes a pin 54 suitably headed to prevent its disengagement from such aperture. The opposite end of the pin 54 is. provided with a head 55 the outer face of which is rounded to engage a seat in the pin 56 carried by the top 3, in a manner similar to that already described with reference to the part 37.

57 designates a spring interposed between the head 05 and a washer 58 loosely mounted on the pin 56 whereby the deflected portion 59 is normally maintained against the stop pin 60. The forward end of the member 50 is bent inwardly and then forwardly so that the forward end of the member 37 is normally seated on the extension or striker 61 of the member 50, said striker riding on the shaft 6 and adapted to be operated thereby as will be clearly understood from the description of the operation. The stop pin 60 is preferably provided with an enlarged head 62 which together with the head 36 prevents the

members

37 and 50 from imin any desired manner but preferably as herein shown which is similar to the manner described and broadly claimed in'my prior patent 940,376, November 16th, 1909.

The operation of my novel ignition-system will now be readily apparent to those skilled in this art and is as follows :--In my present invention the contact mechanism is mechanically operative on the movement of the actuating means in opposite directions and is electrically operative on the movement of the actuating means in but one direction, it being seen that the shaft 10 can be'operated in either direction, and the contact mechanism is constructed in such a way that a contact will be made only when the shaft is operated in one direction.

The shaft 6 is operatively connected with the engine shaft and driven thereby, thus rotating the shaft 10. Assuming that the parts are in their normal position as seen in Fig. 3, as the shaft 10 revolves the member 50 will be moved away from the stop 60 from the position seen in Fig. 3 to the position seen in Fig. 6 which will permit the member '37 to move rearwardlv and abut against the stop 60 as seen in Fig. 3. As

similar manner to that described in my prior patent No. 940,37 6 and I have therefore deemed it unnecessary to describe the same since it is now well known by those skilled in the art.

I will next describe the mechanism employed for advancing or retarding the spark. The arm 12 is connected with any suitable operating mechanism for revolving the housing 5. The result will be that the idler S will be revolved thereby reducing or in-.

creasing the speed of rotation of the shaft 10. It will thus be seen that the rotation of the shaft 10 may be stopped or reversed without stopping the rotation of the shaft 6 or the engine connected therewith. When it is desired to short circuit a cylinder the corresponding pin 22 is depressed thereby causing the member 20 to contact with the casing 1 and with the corresponding contact 14 as will be clearly understood by reference to the right hand side of Fig. 1.
