' Application meaeprn 15, 1912. So -1 REISSUED To all whom z'imag concern:

Be it known that I, EMIL Poonnsifir, a citizen of the United States, residing at 'lh'fiin, in the county of Seneca and State of Ohio, have invented certain new and useful Improvements in Current-Generators and I iters for Internal-Combustion Engines,

0 which the following is aspecification.

This invention relates to igniters of the make and break type and in which the magneto or current generator is combined therewith as a unitary structure that is fastened to the head or other, suitable part'of the engine cylinder, the rotor of the generator being operatively connected with the inov able electrode of the ign'iter so that a recip means operatin on the rotor trip finger agalnst the tension of spring meanscauses the rotor to move to "cocked position while 0 the electrodes of-- the igni ter are broughttogether, and then released from such cocked "position so that the electro-motive force generated 'by the sudden return movement of the rotor through the magnetic field of the generator will produce the igniting current 'Whereby the spark is produced between the electrodes in, the compimsion chamber of the engine. The. combination of means and instrumentalities above referred to is the subject-matter f my pending ap lication for Letters-Pa ent of the Unite States,

.Serial'No. 668,153, filed December 27, 1911,

and the presentinvention relates to improve ments es cially adapted for combined igniters an generators of the type referred to.

The actuating means. for the rotor and movable electrode is mounted on the engine cylinder'or other suitable part and is operatively connected with some moving mechanism and, has no connection with the magneto or igniter, since the actuator, whichmay'be'a push rod, rotating or oscillatory arm or the like, merely contacts'with the trip finger of the rotor. generator must be removed from time to time for cleaning the electrodes and other reasons, it is of great importance tha tlthe igniter and generator be replaced in exactly the same position it was before removah otherwise;the push rod will not be disposed in proper relation to the triptinger of the rotor to. accomplish satisfactory results in the operation of the engine, generator and igniter. The reason for this liabilityof the igniter being replaced in a different position As theigniter and,

tude between the parts being provided so as to facilitate easy removal of the igniter and to obviate the necessity of careful and receiving the body of-the igniter, this lstiexpensive machining and fitting of the parts.

-By reason of the liability to error in replacing the igniter, there is provided an arm or equivalent means onthe igniter body to inter-engage with a. fixed part on the engine cylinder, so that there can be but one position in which the igniter can be attached to the cylinder, and that position is the one where the pushrod .or other actuator is in proper relation" to the trip finger of the rotor. As the" result of this arangement, it is never necessary to adjust the relation of the various instrumentalities in replacing the ign'iter when it has been removed for cleani or any other purpose.

In dition to the foregoing objects and advantages, the invention has certain other minor a vantages which will appear hereinafter as the description proccedsgin reference to theiccompa'nying drawings, in. which,

Figure. 1 is a front view of the combined ,ignite'rgahd current generator applied to the sectional ne on line 33, Fig. 2. Fig. 4%

The igniter B comprises a'cylindricalbody i. which passes through an,.,-o"ning 2 in the cylinder headA, the opt ining 'heing of slightlylarger-diameter than the diameter of the igniter body, so that latter can be easil inserted or removed. B'assin D.

'llic ouier end of the bo iy is for-flied with; a i'liomboiilsl cinch, us sl'aou'n in Fig. i, has bolh openings 6 that. are slightlylurgei' diam ter than the fastening bolts or :-;tu ls 7 list puss tl ntough the openings and are fastened to the cylinder head A Thus, there is considerable latitude allowed between. the body of the ignite: on the one bend and the cyiimler head and fastening bolts on the, other, and by reason of this, the ignites hotly liable to be fastened to the cylinder head in a variety of positions within the limit of this latitude, the disadvantages oil? which have been hercinbcfoi'e pointed. out, butiire overcome by the improvements later to be set forth.

Extending from the plate portion 5 of the igniter body is a shelf or bracket 8 which forms s wise to Wli h the generator I is re moi-ably secureiil by stiul bolts 9. Projecting l rally them the l sclie i oi. shelf 8 is c. n i, t

The outer extremity of lhis extension rod is located at a consideriible distance from the axis of the igniter, end this extremity is adapted to engage some fixed part of the engine, such for instance s lugs 1% on thcsrm 15 in which the operating shel 16 rotates. The lugs 14 are spaced apart for enough for i'he extension rocl to enter between them as the igniter hotly is inserted. in the opening in the enine cylinder, end when thus positioned it. is impossible for the ignite? body to shift ungulzii'ly oi zii ouni'l its axis and thereby disturb lhe propel relation of the ignitei' and generator opemiing means The parts 1%, l2 :inil thus cons tliP means for iniihc pro e-i" no mung of she. igniler the.

Between the polepieces oscillates a cx uciit'omn roioi' ZOmountecl one shaft 21 which' hssizit one. end oppositely-disposed ci'snlz ermsQQ ,which are connected with springsfsS that assume an alining position through the axis oi the rotor when the latter is idle, hhsgonicn ends of the springs being fastened to studs '24: on tho generator frame. 0n the opposite end of the rotor shaft is o tripling-c1125 which is adapted. to have a Wiping engagement with a push rod 26 or othei' equiyaleutactuator. which rod has its end oppositc from the trip linger connected- With the crank pin 27 of the rotating shaft 1G. The push rod or actuator has a combined rccipi'ocatory and rocking movement on a bearing pulley 28 journalcd on a support 29 which is fastened by ll bolt or equivalent means 30 to the arm 10 of the igniter frame, said bolt forming a pivot on which the member 29 can be adjusted to different positions for bringing the free end of the push rod 25 into proper cooperative rclotion with the trip finger 25. The trip finger has a tail piece '01. arm 31 which 18 adapted to be engaged by an arm 32 fastened to the outer end of the movable electrode ii, the arm 32 being held yieldingly against the arm 31 by a helical extension spring 33 which has one end connected with the arm 32 and the other end anchored at 34 on the ignitcr frame. To obtain the proper set of the sparking points of the electrodes with respect to the rotor of the generator, one arm, such as 32, has an adjustable screw which engac'es the arm 31. The spring 33 is of less tension than the-return springs 23 of the rotor and is sullicicut to maintain the arms 31 and 32 in contact during the firstpart; of the cooking movement of tho armature and to maintain the electrodes in contact during the final part of such cool:- ing; movement, it being understood that the electrodes are normally separated, and that they coinc into contact before the rotor or armature finishes iis cocking movement, 1 the position of the rotor shown by dotted lines in Fig i. it the end of the cocking movement, the push rod "26 sli is off the tip of the trip finger, and the springs 23, which have been extended or placed under tension during the cocking movement, quickly snap the I'OEOX hack to and beyond il's normal position, as l]l(ll(21l(2tl by the (lot and dash lines, Fig. 1. This quick movement of the rotor quickly changes the path'of the magnetic fiux through the pole nieces and rotor,

with the result that a high elect-ro-motive force is induced in the generating coils, the maximum electro-moitive force occurring at about the tin'tc the electrodes are separated during the return movement of the arm 31 of the trip finger such arm being adapted to strike the arm 32 :i hammer blow for effecting a quick separation of electrodes. Byrcferring to Fig, 4, the effect of a defective positioning'of the igniter is clearly depicted. Without the use of the positioning controlling psrtsw; 12 and 14, it is possible .for the igniier to be sccurealin either the full line posit-ion c or dotted line Sil cylinder wall.

position Z), because of the latitude provided between the igniter body and the bolts and in other words, the igniter can be fastened to one side or the other, of: its true central position to an. extent. correspending; to the gle 0. Thus, the trip arm of the rotor would in the dotted line position 1: when the igniter is in the dotted raising the active end of the trip rod above the tip of the trip finger. When the igniter body is in the full line position athe trip finger is shifted to the right and thdsrmporting roller 28 is lowered so that the push rod and trip finger will obviously be improperly positioned.' These contingencies can be guarded against by providing the arm 10 on the igniter body and having some means on the fixed part of the engine to engage such arm, such means being the lugs 14-, as in Fig. l, or a bolt'or pin 14 engaging in the slot 10 of the arm 10, as in Fig. 9.
