Application filed January 52, 1913. Serial No. 210,004.

To aZZ whom 2'23 may concern:

Be it known that I, ALBERT Enronson, citizen of the United States, residing at Chicago,' in the county of Cook and State of Illinois, have invented certain new and use- 'iul improvements in Ignition Devices, of which the following is a specification, reference being had to the accompanying draw- 111'.

he invention relates to new and useful improvements in ignition systems and more particularly to an ignition system havmg'an ignition generator wherein the rotor or 111':- mature shaft is oscillated for furnishing current to produce the sparks for ignition. An object of the invention is to provide an ignition. system of the above character wherein the rotor shaft and the trip lever for actuating the same are both moved by a torsional spring. which is preferably arranged coaxial with the trip lever and shaft.

.A -further object of the invention is to provide mechanism of the above character whereinthe movable electrode of the ignition device is actuated by a member dis posed between the trip lever and the movable: electrode, which member is normally out of cont-act with the arm on the movable electrode so as to permit the ignition points to remain in contact as they wear.

A further object of the invention is to provide a device of the above character wherein themember disposed between the trip lever and the movable electrode is forced toward the trip lever by a spring which is of slightly greater tension than the torsional spring when in its released posi-- tion so that said member may be moved away from the movable; electrode.

A still further object of the invention is to provide a device of the above character wherein the torsional spring is supported by a part moving with the trip lever and wherein the torsionalspring-is also provided with a roller which bears against the trip lever.

A still further object of the invention is to provide an i nition system of the above character wherein-the ignition electrodes are mounted in a bracket adapted to be attached v These and other objects will in port bev obvious and will in more fully disclosed,

in the drawings J Figure 1 is a view partly in front elevapart be hereinafter tion and partly in vertical section showing a device embodying myinvention;

Fig 2 is a sectional view on the line 22 of Fig. l;

Fig. 3 is a view showing ,inperspe'ctive certain of the parts, said parts being detached and separated from each other;

Fig. 4 is a vertical sectional view through 'thisbraeket are ignition electrodes carrying ignitlon points and one of the electrodes is" movable. Extending outwardly from the bracket is a rod which supports the generator preferably by means of a perforated lug formed integral with the housing of-the rotor which lug iskeyed to the rod and held thereon by a clamping nut. Also projecting outwardlv from the bracket and in alinement with the axis. of the rotor shaft is a second rod on which the trip'lcver is mounted to turn freely. The trip lever is connected to the rotor so that the two move as one. Said trip. lever has a projecting sleeve around which is located a torsional spring which isco-axial with the trip" lever and rotor shaft. One end of this spring is connected to the bracket while the other end carries a roller bearing on the trip' lever. The trip lever operates directly upon a sliding rod which is adapted to be struck a blow by the trip lever and the endwise movement of the. rod through the action-of said trip lever moves the electrode to separate the ignition points. This sliding rod is spring pressed toward the trip lever and a stop collar limits its movement. Thetension of the spring may also be varied so that said spring in tension is slightly greater than the tension of the torsional spring when the trip lever is in idle or released position. This enables the sliding rod; to

1,10 i move to its limit toward the trip lever and 4 k "thus carry the end thereofout of engagement with the movable electrode so as to permit the ignition points as they Wear to always be in contact.

Referring more in detail to the drawings, nry improved ignition system includes a supporting bracket 1 which is bolted to the outer Wall of the cylinder of the engine in to contact With an. ignition point 7 on the of the rod.

electrode The electrode 4 is movable so as to separate the ignition points 6 and and again bring the same into contact. Un the outer end of the electrode l there is an arm 8. A spring 9 encircling the electrode 4: is connected to the bracket at one end and at the other end to the electrode. This spring operates to normally hold the ignition points in contact. The movable electrode is held seated in the usual manner.

Projecting outwardly "from the, bracket 1 is a rod 10. This rod 10 is rigidly secured to the bracket in any suitable Way. Mounted on the outer end of the rod 10 is a magneto generator indicated at G in the drawings. Said generator includes magnets M and a rotor, the rotor shaft supporting the rotor being: indicated at 11. Extending about the rotor is a rotor housing 12 which is or the usual construction. Formed integral. with the rotor housing is perforated lug 13 through which the rod 10 extends. This lug. as clearlv indicated in the drawings. is located Within the ltshapcd magnets M. The rod 10 is formed with a reduced section Ll which provides a shoulder 15. The lug seats against the shoulder 15 and is held thereag'ainst by a nut 16 which is threaded onto the outer end or the reduced section 14. The rod is preferably termed with a her-var which is adapted to register with the lrev-ivav in the lug and a locking key 17 extended into said key-Ways prevents the magneto generator from movement arziallv about the rdd l0. 1

Also projecting from the bracket 1 is a second rod 18 Which may be. secured to the bracket in auv suitable Way so as to be rigidly held therebv. This rod 18 is in co-ax'ial lnienient Fill; the axis of the rotor ill. .L;i-,-unted to turn on tl. rod 18 is a trip lever 19. The triplever 19 has an inner recess 20 Whi ch its onto the rod 18. The trip lever l9 has a coupling member 21 which is connected to the coupling incinher 22 on the rotor shaft ll. The rot r shaft coupling 22 is formed with oppositely disposed recesses 23-23. The coupling member 21 is formed with projecting lugs same time the rotor shaft E e-24?: which are ads te to extend into and tit the recesses 23 and in this the trip lever is locked or engaged With the rotor shai't so that the two turn as one. At the may be readily disconnected from the trip lever.v Extending from the other side of the trip lever is a sleeve Which is prel ernbly formed integral with the trip lever. This sleeve snr rounds the rod 18- and preterabl efcends from the trip lever to the bracket 1 so that the trip lever is Oil-SlitfiflOHl' the bracket. Extending about the sleeve 25 is a torsional spring 26 which is (to-axially arranged with the trip lever and the rotor shaft. The inner end 27 of the torsional spring is connected to the bracket. The outer end '28 oi the torsional spring carries a roller 29 "which bears against the outer face 30- of the trip lever 19. This roller 29 has projecting flange 31 Which extends along the side edge oi": the trip lever and the flange serves to retain the roller on the taco of the trip lever.

Disposed between the arxi able electrode 4- and the trip lever 19 is a sliding rod Said rod slides in the bearing lug formed on the bracket and also in the sleev 34cwhich is threaded into a bearing lug formed on the bracket. The outer end 36 of the rod .is adapted to bear against the trip lever when said trip lever is in idle or released position. as shown in Fig. 2. Secured to the slidin;-; rod. 32 is a. collar 37. l

8 of the niovupper end of the W hiscollar is adapted to engage the bearinglug 33 and serves as a stop to limit the movement the rod toward the trip lever. A coiled spring; extending about the sliding red 33 bears against said collar 37 and at its other end against the sleeve This spring normally forces the rod to the right, as viewed in Fig. 2, holding the collar against the hear ing lug. llv adjusting the sleeve the tension of the spring 38 may be varied. The end 39 of the sliding rod 83 is adapted to engage the. arm 8' of the movahle electrode when the parts are in idle or released pcsition shown in 2. The end of sliding rod is spaced from tire face of the arm 8. so that as the ignition points i 1'' Wear the spring can turn the EHOVR-lfllfllfifiilffififi so as to maintain these ignition poi; in contact. This results always being in contact when the in released or idle position. tr is operated in the Well linowr. i type of devices.

As clearly shown in o? the n in the ignition points lul This spacing snilicient ment of the generator.

' ish rod so downwardly and release the shoulder -l1 from the projecting lug 42. As the pus-h rod moves to the left, as viewed in n clo wise directioricompressing the torsional spri 26, thus storin uppower in said in The upper enc of the trip lever at time is moved away from the end of sliding rod The rotor shaft is also oscillated by this movement of the trip lever as "he two are connected together and moving: as one. When the shoulder i1 is tripped or disengaged from the trip lever, the torsional spring will rotate the trip lever and the rotor shaft in a counter-clockwise direction, the upper end of the trip lever will strike the sliding rod 33 a blow which will force the rod to the left, as viewed in Fig. 2

compressing the spring 38 which serves in'a measure as buffer spring, preventing Wear on the parts. The other end 39 of this sliding rod 33 will be caused tomake contact vjh the arm 38 so as to separate the points 6 and 7. The parts are so adjusted and timed that the points will be separated just as the rotor reaches the point of maximum current generation. When the trip lever has reached the point indicated in Fig. 2, the torsional spring will substantially have spent the newer stored therein so that there is very little tension in the spring tending to turn the trip lever in a counter-clockwise direction at is time. The tension of the spring 38 ater than the tension of the spring 26 n the parts are in the idle or released position, so that this spring 38 returns the push rod 33 until the stop collar limits this movement. movement of the rod 33 moves the end 39 out 1 of engagement with the arm8 and permits the i uition points to make contact through the onion of the spring 9.. As clearly shown" in the drawings, the torsional spring is mounted on a sleeve pro ecting from the trip ver and this prevents any jam or Wear on the torsional spring through the movements the trip lever. Furthermore, the torsional spring bears on the trip lever through an interposed roller which not only reduces the i 1.. 1011 due to the movement of the spring on the trip lever but also prevents the projecting end 28 of the spring from breaking;

In Fig. 5 of the drawings I have shown a htly modified form of the invention in the rod for supporting thetrip lever 19 extended sons to engage the rotor shaft of the generator. The rod is indicated at 18. Said rod is rigidly carried by the lret'i but projects entirely through the trip lever and the outer end of this rod -eX- tends into a recess or housing 18 in'the end the rotor'shaft 11. The rod 18 insures rhe co-axial alinement of the rotor shaft and the trip lever and prevents any displace the trip lever Will be turned in a y This retracting or returning.

The generator is supp rted the rod 10 and is keyed thereto, in the form of the invention shown in Fig. 1. With this rod 18*, however, extending into the rotor shaft, the keyway connection between. the perforated. 1119," 13 and the rod 10 may be done avvay with. In other words, the rod 18 will pre- .dra'ivin s. the 'e nerator Will be ri 'idlv su ifi ported by the bracket so that it is impossible for the rotor shaft to get out of timing with the electrodes due to any false or improper movementsof the generator on the bracket.

it will be further noted that my improved ignition system which includes the ignition devices and the generator and the actuating" mechanism therefor, are all mounted on a.

single bracket which may be readily removed and replaced. The parts may be all assembled at the factory and-placed on an cnnine and Without requiring adjustment thereof. 1

It Will also be noted that I have reduced the number of parts over that contained in the structures heretofore used and have greatly simplified the structure, as Well as rendering! the same more durable and lasting.

It, is obvious that minor changes in the details of construction and arrangementof 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 Letters Patent, is:
