' My invention relates to engine starters, and it has particular relation to starters for internal-combustion engines of automobiles or other motor vehicles.
. My invention has for'one of its objects to;
provide an engine starter that is automati cally operatively connected to an internal I combustionengin'e upon the operation of the starting-motor.
t -A second objet lo'f'my invention is to provide an engine starter"ofzthecharacter de- -'scribed above wherein a member that-is movablexaxially ofa; pinion operates automativ eally toshiftthe pinion'in-the plane of its rotation into and'out of engagement with a coacting member. p p -An engine starter constructed in accordance with my'invention comprises a member that' is oprativ'ely connected to the shaft. of.- the-startingmotor in such-manner as 'to be moved longitudinally upon the rotation of the shaft. The longitudinally movable member coacts" with the driving pinion to actuate the latter'radially or in the plane of its rotation up the outward movement of the longitudinally movable member.
' In the accompanying drawing,v
Figure 1 is a view, partially in elevation and partially in section, of a portion of an o englneflywheeland an engine starter constructedin accordance with my invention Fig. 2 isaa'view, similar-tolfig. 1, illustrating'the'pinionuin engagement with the fiywheel gear;
Fig. 3 is a view in end elevation of the mechanism of Fig. 2.
Referring to-the drawing, an engine fly-' wheell, only a portion of which is shown, is.
, provided with gear teeth 2. A starting motor 3,:which'may be, for example. an electric mo'tor,=is provided wrtlran: armature shaft 4' having a hollow borcriiidieatedat 5. p

- The bearing 16 is mounted in an oblongslot 21 in the members i 15 and 19 for vertical movement relatively to the latter members, and is maintained in 'horizontal aline'm'ent 79 during this movement by means ofvert ieally: " j extending pins 22 and 23, A spring 24 nor-Q mally holds the bearing 16 and the pinion-18 a in their uppermost positions in which] they are illustrated in Fig. 1.' I '3 The pinion,on its side adj acent to the motor, is provided with a'fiange 25 and with a relatively deep recess 26 that is tapered at its in ner portion at substantially the same angle as the conical surface 11 of the shaft 6. The flange 25 carries a pin 27 that extends into the slot 10 in the flange 9 to operativelv eon nect the pinion 18 to the shaft 6 and thereby to the shaft 4 of the motor.
Normally, the several parts are'in their rc- 5 spective positions in which they are illustrated in Fig. 1. When the motor 3 isenergized in any usual or suitable manner by meansnot shown. the shaft 4 rotates in a vclockwisedirection, as viewed from the left v the slots 8 that are enfiafiedfbyjthe pin 7.
The 'longitudinal outward movement of v the shaft 6 causes the conicals'urface'll to eie'r't a cam action upon the inelined surface of thejrjec'ess 26 in the pinion 18. and the lat- 1 ter, together with thebearing '16 and pins 22 aind 23i' are moved downwardly against the force of the spring 24 until the shaft 17 is in aitialaline'ment with the shared The parts are' -thenin' theirrespectivepositions in .105 which they are illustrated in Fig. 2, the pin-' ion 18being completely meshed with the flywheel gear 2. The motor thereupon drives flange 9, "pin 27 and flange 25.
