To'aZZ whom 'it may concern:

Be it known that/I, PAUL B. FANT, a citi= zen lof the United States, residing at Newark; in the county of Licking and State oi? Ohio, have invented certain new and useful Improvements in Timers for Combustion'- vEngines, of which the'followiug is a specifi-4 of A'to its fnounting.

' V,at hig .the bottom of t e casing cation.

This invention-'relates toimprovements in sparkling devices-for ignition systems in corr- Junction with 'variable s eed` combustion engines, and particularly. or increasing the spark crease the spar efiicieney atnny rate of A further object of this invention is the provision of a simplified form of centrifugal 'device for operating automatically with 'Increase in speed., to effect anv increased s peed nndudecreasethechance of the spark the engine is operating le'ngth lo contactbetween the'contact elements of the timer.

-`In the aceox'npanying'ldrztwings wherein." likenumerals refer to llkeparts, Figure 1 is 'a planview .of 'my invention with the infer 'removed and 1nv4 coninnctlon with a common, f orfmof ign`1t1on .c1rcu1 t. Fig.- 2

Fig.4 is' a detailed view partly in section of the preferred forni of electrical .contacting device,- 'and, Fig. is a detd-ilplanview ofjcc'ntrifugally operated member. of g e'timer with especial Areference In the drawings, in the preferred formfo'fmy linvention is open l' at oneside, Crucible-Lilie' n-sha-pe and opezi at one. side' as shown."

In the centers of said faces arctap ed holes, in alinementvwith each other, or the reception of pivotal bolts 20. The'otlier branch of the forked. member 12'is thear'm 13, circular in cross.- -5

Around the inner ing 6l arelaid metal c segments 38. The metal ic;A segments, besides being insulated from eachother are insulated from the casing 6 by suitable material 36. For securin themetallic se ments to the sidewalls o the casing, an for affording a means for connecting them in the electrical circuits of the ignition system, are provided bolt Shanks 39, integral with said metallic segments and extending throu h holes 40 in the casing 6 and insulated t erefrom by a continuation of the material 3'6. On the outer ends of said bolts are insulating washers 41, clamping nuts 42, and on one set additional nuts i3 for firmly holding connection wires 44 of To avoid raising of.
