Description

W. L. MCGRATH.
ENGINE STARTER.
APPLICATION men APRA, 1919.
$329,535. iunm Feb. 3, 192() of proyer meshing ure enormously increased mi Ille chances ol' abutting end to end are reduced to a. minimum.
It is ovious that when the pinion teeth are presented to the y wheel teeth somewhat out of register, the letter teeth will Sir/rik@ against.' the inclined surface 7d whereulmn the pinion will be moved slightly so ne, to xeuse proper xegieiwer. Moreover by having the cutaway portion THy the pinion teeth will be permitted to enter the fly wheel teeth without :my contact. between sueh Hy wheel teeth und the broad fuee 7 of the pinion tooth, 'iermittiiw the lower portion ol' enel: tooth, tlmt is Said portion 7d, to first contact the fly wluel teeth and be guided or moved into proper register.
`he described construction of the pinion teeth is such as to eimit of the ready mesh ing thereof with t e lv wheel teeth whether cluunfered or not an Whether rounded es shown in Figs. 1 and 6 or not.
I claim:
For use in un engine Starter transmis .wiou or drive, a pinion having the enger. end o eheh of ils. leeli rut away substrintinlly vertically :il: an angle lo its longril tudinel exis, el; uil 'living curved from :L point slightly i linee. of the tooth :sud extending; emilie: d j; into the tenth `und iheuee upwardly te che op edge of the tooth.
