To all whom 2f may concern:

Be it known that l, Henin? Hess, a citizen of the United States, residing at l/Vava, in the county of Delawareand State of Pennsylvania, have invented certain new and useful Improvements in Starting Devices for Explosive-Motors, of which the following is a. specification, reference being had therein to the accompanying drawing.

`his invention relates to means for starting that type of motors ior automobiles which are operated by explosive charges ignited by an electric spark generated by a dynamo or Z sparker driven by "he motor, the aim of the invent-ion being to start the motor without cranking or manually turning` the motor shaft., or parts connected therewith. l

lilith this end in View, my invention consists of improved means tor actuating the dynamo independently of the motor, a spark may be formed in the motor cylinder to ignite the charge therein without the necessity of cranking the motor shaft, which would be necessary it the dynamo were incapable of independent operation. This result is accomplished by interposing between the' dynamo and the motor, mechanism adapted to permit the continuous driving ot' the dynamo from the motor as usual, but adapted to permit the disconnection of the motor from the dynamo, so that the lat ter may be operated or turned over independently ot' the motor.

ln the operation of my improved mechanism., the independent actuation of the dynamo will ignite the charge in the cylinder and start the engine, and-the latter in its continued operation will take up the motion oit the dynamo and operate the same continuously and normally.

My invention consistsl also in an improved form ot the driving connection between the motor and dynamo, adapted, after-the independent operation of the dynamo and when the latter is again connected up with the motor, to preserve their phase relationship.

ln the accompanying drawings: Figure ,l is a side elevation ot a mlotor and dynamo, showing the same connected in accordance with my invention; Fig'. Q, is a tace view on an enlarged scale ot the independent driving means toi-'the dynamo,sho\ving the latter connected for continuous operation hy the motor; Fig. 3 is a side elevation oit the so that saine with parts in section; Fig. l is a sectional view on the line -A of Fig. 2, showingthe motor and dynamo disconnected tor independent operation o' the latter.

Referring now to the drawings: l represents a motor comprising power cylinders la, lb, etc., provided with pistons, as usual, coupled to the driven power shaft 2, which shaft may he geared in any suitable manner to the wheels ot the motor car 3. The pistons are given their power strokes by the explosion ot' compressed explosive charges in the cylinders, which charges are ignited by an electric spark produced by means oi' a dynamo or magneto-speaker 4:, suitably sustained hy the frame of the carand having its rotary armature driven from the motor, trom which armature the current passes by means ol conductors 5, 5a, etc., to the in'- terior of the respective cylinders, the rotary motion ot the armature delivering a spark to the interior o the cylinders in succession and thereby igniting the explosive charges compressed therein. The foregoing parts maybe of any-appropriate and customary construction, and, except in so tar as hereinafter indicated, they of themselves form no part of thisl invention.

in applying;` my invention, ll so torni the driving` connection between the mot/Or and dynamo that7 while under ordinary and normal conditions the dynamo will be driven continuously by the motor, the two may be disconnected and the dynamo driven manually and independently of the motor, so that a. spara may loe produced in the cylinders by the manual operation of the dynamo without at the same time operating the motor shaft or parts connected therewith. This result and mode of operation is preferably etiected by providing` the armature shaft with a driving pinion 7, adapted to be driven normally by means o' a driving clutch disk 8, receiving its rotary motion from the motor sha-ft 2 through the medium ot a counter-shaft E), to which the driving clutch is connected, a pinion 10 'on the counter-shaft and a pinion 11 on the motor shaft meshing with pinion 10. The clutch disk is adapted to be disengaged' from driviing` connection with the armature shaft, and the latter driven independently by means of a gear wheel 12 adapted to be operated manually, preferably fi the drivers seat, and in such manner that operated 7given usuai 'irre shaft ndependentiy or the motory and tne necessary produced to the ellarges in the eyiind-ersa he dri ving clutch disk 8 spiined to the oonnterenaft i) so as to oe inovabe lon:- ltudinallv tnereon the disl seine; acted on hy a. spirai spring '1- circiing the shatt and oeari i machine freine and disk rcs and to norinaliy lio-id the d ggiy in 1ring engagement with the armati-ire parte comprising a lng ifi on the tace of tlpinion te heengaged hy a driving; adgaeent` Jrace the elnteh pinion, o e driving connection between these tion temi oit the gear wheei l2 such when 'tn iea hy hand it will nrsd automaticaily dif ngage the driving ciutch disk from the j oinion, 'then engage with Vthe pinion and impart to the latter a partiai revoiution, after ivnieh it will automatically disengage from 'the armature pinion and permit the rengagement therewith o the clutch disir, rEhis is effected by providing at intervals on the Wheel, a series o driving gear teh l2, 12b, i2-C and teeth are to mesh with the teeth of the armature pinion and give the same a partial turn, in the -present'instance about haiiC a revolution' Near the edge of the Wheel l2, on its rear tace, are a series of cams 16, corresponding in no mber and iocation to the series of gear teeth thereon, which cams are adapted, when the Wheel is turned, to engageithe face of the clutch disk and force the same back against its spring and out of driving Connection with the armature IpiniOn, as shown in ig. e, thev disengagement of the clutch disk taking piace co-inoidentiy with the engagement of the gear teeth with the armature pinion, the crutch diei being heid ont ot engavement with Athe pinion nhiie the gear Wheel 1s in engage therewith. To effect this the cams each formed with an inclined forward face jefa, and a rearwardly extendingl face 16, the former acting 'to engage the clutch disk and push it gradualy out of engagement with the armature pinion, and the face lob acting to hold` the same out of engagement, the form and relation of the parts being snoh that by the time the last tooth of the series noe-aiesot teeth on the Wheei l2 ieaves the armature pinion, the end of the face 1U Will pass beyond and disengage the ciutch disk, and alien the latter to he pushed by its spring haelt into position where its ing l5 Will be :in the path of the lug on the armature piniono The mutilated i9, may be operated ,annally hy any all ronriate means, but l refer to adopt the oonstrnetion shown in 3, Where it he seen that the wheel 'ionnted on the turn is mounted suitable hearings, and s fined to it a ratehet Wheel 18 engaged J a driving jgayvi 19, piyoted to an operatlever 2O mounted to ulcrum on the end i the shaft, the movement of the lever in he direction of the arrow 2) serving o impart a turning motion to the shaft and acting to cause the Wheel l2 to be moved in the direction of the dotted arrow in said tignre. These connections for the manual operation of the Wheel may be extended to the driver-s seat, and the operating lever formed to be actuated either hy'the hand or footg'it heing hutnecessary to give the lever a forcible push to canse the proper impulse to he given to the mutilated gear to effect such a movement of the armature as to produce the igniting spark.

lfn order to prevent the mutilated gear `Wheel from being given a greater motion than necessary by reason ot' the suddenness of the'impulse given to it by the operating lever and in orde;` to maintain the Wheel .in

proper relationshipafter starting, Wit-h ref erence to the armature pinion, l provide on the tace of the Wheel. a series of sockets or depressions 2i, corresponding in number to the series of gear teeth, which socket-s are adapted to receive a spring actuated plunger 22, sustained by the frame, the parts loeing so positioned relatively to the series of gear teeth on the Wheel 12, that when the plunger engages With one of the sockets, the Wheel will be held with its gear teeth disengaged from the armature pinion, ready Jfor the engagement of the next series of teeth with said pinion on the succeeding motion of the Wheel.

By reason of the factthat there is but a single point in the rotation of 'the clutch disk and armature pinion, Where the disk can engage and drive the pinion7 it Jfollows tho-se parts when engaged will always preserve the saine reiation to each other, so that the phase reiationship of the dynamo and motor is not disturbed in the operation of disengaging the parte :tor manual-action and again' connecting them. for normal action, i
