IGNITION DEVICE.
Patented Jan. 6, 1920.
Application filed October 13, 1917'. Serial No. 196,372.
I To all whom it may concern:
a specification, reference being had to the accompanying drawing.
The invention relates to new and useful improvements in ignition devices for internal combustion engines and more particularly to an ignition device including ignition electrodes, a generator and a trip-operated spring actuated mechanism,- for the generator and electrodes.
An object of the invention is to provide an ignition device of the above character with a two-part supporting bracket, one of which parts carries the generator and is vertically adjustable relative to the other parts to accommodate the generators where the shafts are of different heights.
A further object of the invention is to provide a two-part supporting bracket of the above character wherein the part carrying the generator ismounted upon and carried by the other part which supports the electrodes and the spring-actuating mechanism and wherein the connection between the parts of the supporting bracket is such as to maintain the supporting shelf for the generator in a horizontal position independently of the clamping bolts which unite the two parts of. the bracket.
A stillfurther object of the invention is to provide a two-part supporting bracket of the above character wherein the part car-' rying the generator may be vertically adjusted relative to the part supporting the trip lever for the purpose of varying the time of maximum current generation relative to the time of breaking the contacts of the electrodes.
These and other objects will in part be obvious and will in part be hereinafter more fully disclosed.
In the drawings, which show by way of illustration, one embodiment of my invention:-
Figurel is a view artly in side elevation and partly in section showing an ignition device embodying my improvement;
2 is a front view of the same, the
tuating mechanism; Y v

generator being removed to show the ac- The invention broadly consists in an ignition device including ignition electrodes,
one of which is preferably movable for a make-and-break ignition. Current is ,fur-
.nished by a generator having a flux shifting element, which is oscillated for producing ignition current. The movable electrode and the flux shifting element are actuated by a trip lever which is moved, by
springs for effecting the movement of the v electrode and the generator shaft. A pushrod moves the trip 'lever and releases the same. The ignition device is supported by a two-part bracket. One of the parts of the bracket carries the electrodes, the trip lever and the springs for actuating the same, while the other part oflthe b'racketcarries the generator only. The part of the bracket carrying the generator is mounted upon and supported by the other part of the bracket. The, part of the bracket carrying the generator is in' the form of a shelf and this shelf is vertically adjustable whereby the said.
shelf can be properly positioned tosupport the generator, so that the shaft of the generator will be in alinement with the axis of the trip lever. There also may be times when it is desirable to raise or lower the shelf to vary the position of the axis of the shaft of the flux shifting element of the generator relative to the axis ofthe trip lever, for the purpose of retarding or advancing the time of maximum generation so that it may accord with the timeof separating the electrodes for producing the spark.
Referring more in detail to the drawings which show one embodiment of the invention and my improved ignition device includes, a two-part supporting bracket, one of which is indicated. at 1, and the other at 2' The supporting part 1 carries a sleeve 3, which is adapted to extend through an opening in the wall of the cylinder, which wall is indicated at W in the drawings. Mounted in this sleeve 3 are the electrodes 4 and 5. The electrode 4; is fixed while the electrode 5 is movable. The electrodes are provided with ignition points 6 and 7 which are adapted to normally contact and which pin 10 while the other end is attached to a roller on the pin 13 carried by an arm 14 projecting from part 1, of the supporting bracket. One end of a spring 15 is attached to a roller on the pin 11 and the other end is attached to a roller on a pin 16 which is carried by a downwardly projecting part 17 of the supporting bracket 1. c
The trip lever is moved in a clockwise direction by a push-finger 18 which is adapted to engage a shoulder on the trip lever and release the same when the trip lever is return movement of the trip lever through the action of the springs serves the double function of separating the ignition points of the electrodes and operating the generator. The movable electrode 5 carries the arm 19 which lies in the path of a cam projection on the trip lever. A spring 20 bearing at one end against the arm 19 and at the other end against an abutment 21 iarmally moves the electrode, so that the igmtion points are brought into contact.
The generator is indicatzd at G in the drawings. This generato is mounted on part 2 of the supporting bracket which is in the form of a shelf having a flat horizontal surface 22. Bolts 23 passing up through the shelf are threaded into the base of the generator for holding the same in place on the shelf. The armature or flux shifting element of the generator is provided with a forked arm 24 which is adapted to straddle the pin 10, so that the movement of the trip levers ,are imparted to the armature or flux shifting element. The part 1 of the sup-' porting bracket is formed with a vertical recess'25, while part 2 of the supporting bracket is formed by a vertical rib 26, adapted to seatin said recess 25 and to fit the same. A bolt 27 is secured to part 1 of the supporting bracket and extends through a vertical slot in part 2 thereof. This bolt permits the supporting part 2 of the bracket to be vertically adjusted and holds the same in adjusted positions.
From the above description it will be apparent that the thrust of the push-finger on the trip lever and the strain incident to the actuating ofthe springs is carried by the.
Then again, if any strain occurs through the movement of tne armature or flux shifting element by the trip lever, it is brought directly against the vertical rib connection between the parts of the bracket, and not against the supporting bolt for the part of the bracket carrying the generator. By loosening the winged nut on the bolt 27 the supporting part 2, of the bracketmay be readily adjusted. This vertical adjustment of the supporting shelf with the generator enables generators having shafts of different heights to be used. By adjusting the shelf the axis of the armature shaft may be brought into alinement with the axis of the trip lever, which if the parts are properly constructed, brings about a maximum cur rent at the time the electrodes are sepa rated for producing a spark.
If, however, it should occur, throiugh faulty construction, that a maximum cunrent is not produced at the proper time, the\ generator shaft may be raised or lowered to vary the time of maximum current generation. The trip lever and the arm of the movable electrode are perfectly formed without adjustments, so that the trip lever will strike the arm to separate the i ition points at a fixed time. At this time t e pin, on the trip lever which actuates the armature, will have a predetermined angular position relative to a vertical line passing through the axis of the trip lever. It will be apparent that if the generator is raised to bring this axis slightly above the axis of the trip lever, the time of maximum current generation will be advanced, while if the axis of the armature shaft be dropped, the time of maximum current generation will be retarded.
It is obvious that minor changes in the details of construction and arrangement of parts may be made without departing from the spirit of the invention as set forth in the appended claims.
-Having thus described my invention, what I claim as new and desire to secure by Let-- I tically relative to the part of the bracket carrying the trip lever.
