WILLIAM n rnosr, or ISCHENECTADY, NEW YORK, ASSIGNOR T0 GENERAL-annotate COMPANY, A CORPORATION on NEW YOBKJ'J' I jMAGNETO-DRIVE FOR IN TERNALQCOMBUSTION, ENGINESL To all whom it may concern: Y
.Be it known that I, WILLIAM H. F Ros'r,
a citizen-ofthe United States, residingat- Schenectady, "county of Schenectady, State of New York, have invented certain new and useful Improvements "in Magneto-Driyes for Internal-Combustion Engines, of which the following is a specification.
-' to each other.
: This'invention relates to internal combustien engines, and especially to those in in two or more groups placed at an angle In one form of engine, for example, there may be eight cylinders arranged int two groups, 'foui' cylinders in each group, andlthe crank shaft-may have four cranks,-the connecting rods being so Provision must therefore be made for .pro-.
arranged that each pair of corresponding pistons can be coupled to'the same crank. Owing to the angular relation of the cylinders in each pain-the timeof ignition in one will not coincide with that in the other.
ducing the ignition spark in the second cylinder in each pair, when the common;
crankhas made a certain angular advance from the position it occupied when "the spark was producedin the first cylinder of the pair; As the angular displacement (Hi the two cylindersmay-be somev o'dd number of degrees not evenly divisiblev into 360, it
is evident that-the problem is not-an easy one when reliance is placed. upon; only one source of igniting current, such as a magneto. 9 I
Various attempts have been made toovercome the difliculties andcomp'lications of this situation, and my invention aims to simplify and at the same time solve the trouble: Moreover the construction-which l have; devised enables me 'to"suhic'iently ac--.
celeratethe armature i-n the'field magnets of the magneto or magnetos so as to produce a good spark at the proper time to start an engine, thus overcoming the difficulty of suilieiently accelerating the mag neto armature by the rotation of the shaft of an engine by hand 'lhis'fe'ature is applicable to engines of any type, whether single or multiple cyl nder. Inorder to accomphsh theseresults, I mount the magneto in Specification of Letters Patent. Application-filed September 13, ii-ii Serial na'cna'osa, f; I

inan arc concentric withthe driving gear.
I am aware that it,.has been proposed to rock the .field magnet ot a magneto angle larly aboutthe axis of the armature shaft in order to advance or retard the spark,-but this is a different proposition from. theone herein set forth, wherebythe entire..magnetois shifted bodily from one. angular 60. position to.- another around the periphery This means that the armature is-frotated in the magneto-field during its lateral movement of revolution with the magneto around said gear, This rotation of-the armature induces aspark. at the point of the'maximum induction, if the motion is sufiiciently rapid, .so that a charge in a cylinder can be exploded;
Then the engine has m'orethan'one cyl -170 inder or group of'cylinders; I employ separate m a netos one for each groupiofv cylinders, dach with" its armature so setwith relation to itsfield magnets that the point of maximum induction occurs at the {K013631175 'instant for that particular group of cylin ders. The magnetos are geared to the same driving gear so that they always maintain the same diiierence in times of sparking. They are mounted in sucha mannervas" to 80. becapable of angular adjustment"concen tric'witlnthe driving gear in orderthat' the sparks may be advanced or retarded simultaneously and to. the -same extent'in' 'the groups of cylinders by shifting said mag netos bodily in one direction orthe other, and this'const-ruction also permits the pm; duction sparks for starting the groups of the magnetos simultanetmsly; a In the accompanyingdraWingsLFigure 1V isan end elevation of aportion of a multicylinde'r "internal combustion engine? embodying myinvention. 1 'Fig." 2 is a diagran'imatic' View," showing the relative far- 'rangement of the cylinders, cranks, etc, and Fig. 3 is a side elevation parts shown in'Fi'g. 1'.
