` JULES ALBERT AoERoN AND BLAISE vJEAN MARIE REMY, or LYON, FRANCE. EXPLOSION-MOTOR-STARTING YMEQHA'NISWI- ICI To wr! whom t may concern:

Be it known that We, J ULEs ALBERT Asn RON and BLAISE JEAN MARIE REMY.Y citizens of the FrenchRepublilc, residing at Lyon, France, have invented certain new and use` ul Improvements in Ex losion-Motor-Stsrif ing Mechanism, of wh'ic the following is e specification.

's invention relates to explosion motor starting mechanism in which the motive force necessary for overcoming the resistance of the erplosion motor to the rotation of its crank shaft previouslyto the occurrence of an explosion therein, is derived from s. fluid under pressure.

The improved starting mechanism is illus` trated in the ennexedfdrewing in which :fe FI e '1 is a section online A-A of Fig. 2 and ig. 2 is a. plan partlyin section showing part of the frame of a motor or of a motor car and of the motor starting shaft with the im proved starting mechanism e plied thereto. 'g. 3 is a front elevation and) ig. 4s horizontal section on line B B'eFig. 3 illustrating another form of the improved starting mechanism.

In Figs. V1 and 2 c may represent the fronttransversc member of ia motor car frame, or any membertransverse to the am's of the motor.

Y The spindle revolution in the brd f is s socket to Whc c' and in the bracket l.

This nut i e" apes the spindle r.- The nut i is normallyngeli from e cal by e setscrew 7'.
