COMBUSTION ENGINES.

' Original application fled 81, 1923, Serial No. 654,879. Divided and thil'application fled Decemb'er 1 i 1 11, '1923. Serial No. 680,009.

To all w kom it may concerns Be it known that 1, Julius COURTIER, citi- *zen ofthe Republic of France, of 20 Rue 1 Ernest C'resson, Paris, France, have invented Restorer of Normal' Ignition for Dual-' Ignition Apparatus of Internal-Combustion Engines, of which the following is a full, clear and exact description.

This invention relates to an auxiliary ap-' paratus for internal combustion engines hav ing dual ignition forproducing rcgulable into .a plurality of

contacts

34, 34, 34",

breaksparks foridoing away with niisfires due to the sooting of sparking plugs and automatically cleaningthese plugs during the running of the engines and of the vehicles driven by them.

This invention over applicants copending application 654879 filed July 31, 192cm that it permits of normal ignition in a circuit fed by one source, while at the same time permit- I ting the introduction of a seriesof avariable number of breaking sparks in another circuit fed by another current sdurce. The present improvement also has a circle divided into two conductive segments and two series of separatecontacts, said circle being controlled by the operating handle assing under the pair's-of fixed K1 rangement is independent of the 'magneto which latter is combined with" the earlier construction.

This apparatus permits a single controlling organ to efi'ect the introduction of break sparks regulable at will, separately into one or the other of two ignition circuits. "The general arrangement is such that when the apparatus is at rest-the two ignitiong work -without any secondary spark ap, and when one of-the .iglmtions is work-' mg with break sparks the ot er ignition continues to work "without break sparks.

The invention is clearly illustratedim the accompanying drawin s, in which:-

, Figure 1 is 'avertica sectional view of .an arrangement of'a'pparatus comprising for each ignition a conducting armature coin-'5 posed of two, parts, the one continuous and theother-divided by gaps into multiple ,con-

stacts, 'andtFigure 2tis a detail of a slightly modifie arrangement of ental. sectional the apparatus, 4 Y

The apparatusshowii comprises an insulating support2 in the for'm of a rotacovers an, improvement oreover this artably mounted in a casing 6. This insulat it to be turned about its pivotal axis A one on ;each side of adiameter. Eachof theconducting armatures A", A, comprises a

continuous segn ent

30, 31, and a segment cut by the

aps

32,32, 32", etc. and 33, 33, '33. etc.- dividing it etc. and 35, 35', 35", etc.

. nsronmor woman. rein'rrorr' IOR DUAL-IGNITION Arrm'rus or rn'rmnning disc is provided with a handle 26" which Non-conducting partitions 36, 36', elec- I trically insulate the armatures A ,'A from each other.-

- Upon the casing 6' am rigidly fixed the terminals Y17 and 5, and 17, and 5', for connecting the apparatus within the double ig- I nition circuits.

These terminals are directly connected with nuts which secure the metalsprings 37 38, and 39, 40, terminated

bybrushes

41, 42, and 43, 44, which remain in contact with the armat-ures-A and A, both whenthe ap-' par'atus is in its normal position of rest and introduce secondary spark g'a s.

In engines wi h fixed cylin ers,

nections, between the collector and the distributor of 'the magneto of thefirst ignition circuit through its terminals 5 and 17,

'also'when it is brought into operation, to-

the apparatus described is inserted so/that it is airranged, as far as concerns the electrical conand between the collector and the, distributor of the magneto of the second igniti'onbircuit 'throu h its terminals 5 and 17".- .As

concerns t egelectrica'l connections to 1'0- tary engines, the apparatus'is inserted between. the collector of the magneto andthe distributor of the cylinders of the first and of the second ignit on circuits respectively- "through thesaine terminals 5,- 17 and 5,.17 .1

' The operation of the device is as follows:

su ose the electric current'of'the i ition I enters the apparatus by the flexible wire 45 and leaves it y the flexible wire 48.- When the a'paratus is at rest the cir- I p p ythe flexible wire 46, and the ignition'current M enters the aparatus by the {flexible wire 47 and leaves is closed by the continuous blade' 31 between the two brushes 43 and 44.

For restoring the ignition of the fouled sparking plugs and for cleaning the same, if the-misfires are produced in the ignition circuit M the handle 26. is, moved in the direction of the arrow a. "The brush 41 leaves the continuous segment of the armature A in order to pass successively over the associated fractional contacts 34,

34', 34", etc. of this armature. The

gaps

32, 32', 32", etc. areintroduced in this 7 manner into the ignition circuit M thereby roducing break sparks conjugated in seriesn this circuit.

During this time the armature A' turns I also in the direction of'the arrow a. The

' brushes 43, 44, do not leavethe continuous blade 31. but slide upon it and the-ignition circuit M remains c osed without any secondary spark gaps.

' When the number of break sparks in se-.

ries introduced into the ignition circuit, M is suflicient to reestablish'the normal .spark-.

ing at the points of the fouled sparking plug and the misfiresare no longer hear the handle 26' is secured in the place to which it has been moved, thishandle being j provided upon its lower face with a stud 28' adapted to engage in one of the notches 27 with which the casing 6 is provided; At the end of the time necessary fo'r cleaning the sparking plug the handle 26' is returned to the mediumiposition in which the apparatus is at rest and the two ignition circuits operate again without break s arks.:

If the misfires are taking place in te. ig-

nition M, the disc support 2' is turned in the direction of the arrow' 12'. The b'rush 43 leaves the continuous blade 31 of b11681? mature A" and passes successively upon the

contacts

35, 35', 35". S arks electrically arranged in series are pr need in the associated'

gaps

33, 33', 33, etc. nitioncircuit M. n v f During this movement the ignition circuit M remains closed without secondary spark gap for the brushes'41 and 42 while a in the igsliding remain in contact with the continu{ ous blade ofthe armature A".

In another constructional form of the ap- 1 continuous blade and .a bla'dp tinuous conductin vide paratus, the

brushes

41 and 43, wheii leaving respectively, through the motion'of the disc break spark jumps between 41 and the

contacts

34, 34, 34" or between 43. and 35, 35", 35", the break sparks in series continuing to jump in the

gaps
