IIIlIIIJIIIII/llllllll UNITED STATES PATENT OFFICE.
WILLIAM MULHOLLANI), OF BELFAST, IRELAND.
Specification of Letters Patent. Application filed November 11, 1909.
Patented. Dec. 20, 1910.
Serial N0. 527,431.
'1?) all whom it may concern:
Be it known that I, lViLLIAM -'l\ltn.noL-
LAND. a subject of the King of England, and .i'esident of Belfast, Ireland, have invented Improvements in Magneto-Ignition Devices for Use in Connection with Internal-Com.- bustion Engines of which the following is a specification.
This invention relates tion. devices for use in connection with internal combustion engines and the improve ments consist in providing means for mechanically advancing and retarding the ignition while retaining the maximum spark in to magnetodgniall positions whether fully advanced or fully retarded thus rendering magnetodgnition equal in flexibility or adaptability to accumulator or battery ignition.
The invention is especially adapted for use with magneto-ignition devices c0-nstructed on the Bosch and other well known systems.
In order that my said invention may be properly understood I have hereunto appended an explanatory sheet of drawings, whereon:-
Figure 1 is a side View of a magneto-ignition device constructed under my invention Fig.2 is a sectional plan of same taken on the line All, Fig. 1. Fig. 3'is a sectional end view taken on the line C, I), Fig. 2. Fig. dis a detail view.
In carrying out my invention I mount the magnets a on a suitable base 5. as usual, and fitted to or forming part of the base 5 is a hollow bracket or sleeve 0 which has fitted in it a hollow coni'itershaft d preferably slightly tapered and screwed at one end for the reception of a toothed Wheel 6 which gears with'a. corresponding wheel f fitted on the armature spindle g. This toothed wheel 0 may be suitably secured onthe tapered screwed end of the hollow c0untershaft (Z by means of a jam nut or its equivalent it.
The hollow countershaft d is preferably provided with a collar or the like about midway of its length and fitted loosely on the exterior of said hollow countershaft d is a driving pinion actuated by achain drive, pinion drive or in other convenient manner from the usual half-speed or other suitable shaft. The driving pinion j is made with a boss or sleeve j which extendsalong the exterior of 'thehollow countershaft so pmion j.
that its end bears against the collar or the hke 71 formed thereon. V
Fitted in the hollow countershaft extending a short distance beyond one end thereof is another shaft In which is capable of being moved backward and forward longitudinally and is provided with a pin or its equivalent Z which projects at right angles therefrom.
The boss j of the driving with a short or helical slot at while the hollow countershaft (Z is likewise made with a slot'n parallel to its axis the arrangement being such that the pin or its equivalent .Z fitted on the longitudinally moving shaft 1: projects through the longitudinal slot 22. in the hollow countershaft into the volute or helical slot 912 in the boss 7' of the driving In order to prevent the ends of the projecting pin Z abrading or Wearing the interior surface'of the hollow bracket or sleeve 0 where they come in contact with same an additional liner or casing 0 made of harder metal may be fitted in the interior of the bracket or sleeve.
The projecting end of the longitudinally moving shaft 7; has preferably fitted-to it an end piece 0 to which one arm of a bell crank lever Q is suitably secured. In order to allow of freedom of movement this end piece 0 may be provided with a ball bearing or such like 7).
The bell crank lever Q issuitably fulcrumed at 1" to the base 6 carrying the mag nets a andlas already stated the one arm Q thereof is connected to the longitudinally moving shaft is while to its other arm 9 is secured the lower end of the usual advancing and retarding lever s.
The arrangement "of the mechanism is such that when the advancing and retarding lever s is raised or depressed the longitudinally moving shaft k is actuated either in one direction or the other and in such longitudinal movement the projecting pin or its equivalent Z in said shaft the slot at in the hollow as said helical slot at in the sleeve or boss j of the driving pinion j and as this latter is capable of a certain amount of rotary movement on the h low countershaft-d its inovement can be eit e1 advanced or retarded in accordance with the direction of movementof the longi-- tudinally mogjgig'shaft is; As the driving moves freely along countershaft d but pinion j is made pin Z also projects into the volute or pinion j is directly connected to the armature of the magneto it will be obvious that when the movement of the pinion is advanced or retarded the armature is similarly advanced or retarded.
By advancing or retarding the movement of the driving pinion j and the armature of the magneto in the manner described through .7 the medium of the lever 8, bell crank lever dust-proof and therefore more suitable for exposed positions than advancing 'or retarding mechanisms hitherto used.
Having fully described my invention, what I claim and desire to secure by Letters Patent is Improvements in magneto-ignition devices, comprisin in combination, an armature spindle and a gear wheel thereon, a
through base, a sleeve carried on the base, a slotted, hollow countershaft in said sleeve, a toothed wheel which is carried by said eountershaft and gears with the wheel on the armaturespindle, the said counter-shaft also being slotted, a collar on said coun-tershaft, a driving pinion carried on the latter, a slotted boss integral with said inion, a longitudinally movable shaft (5) arranged inside said hollow countershaft, a pin carried at the end of the shaft and adapted to project the slots in said boss and said countershaft, an end piece at the end of said shaft, a bell crank lever fulcrumed to the base, one arm of said lever being piv oted to said end and retarding lever secured to the other arm of said bell crank lever, substantially as described and shown, and for the purpose set forth.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. 7
