Definitions

  • My invention relates to a starter for an engine, more particularly an internal combustion engine, and the object thereof is to provide a simple and eliicient device of this nature and having the general characteristics of the starter shown in my Patent No. 1,25%,19G, issued to me on January 22, 1918.
  • My invention concerns more particularly the drive or transmission of an engine starting system and the embodiment thereof as herein shown is characterized by a rotatable shaft (either power or hand driven), provided with preferably a plurality of coiled springs on which are mounted the driving member, (such as a pinion), adapted to automatically' travel or advance in a direction longitudinally of the shaftl to engage a rotatable engine member (such as the toothed fly-wheel), and to thereupon rotate with such shaft to rotate the fly-Wheel and thereby start the engine.
  • a rotatable shaft either power or hand driven
  • the driving member such as a pinion
  • a rotatable engine member such as the toothed fly-wheel
  • the spring serves as a yielding driving connection in the starting of such engine member, and the subsequent rotation thereof, and also as a cushioning means in case of abutting of the pinion teeth and fly-wheel teeth end to end.
  • Figure 1 is an elevation ofl a starter embodying my invention.
  • L Fig. 2 an end elevation of thepinion.
  • Fig. 3 an elevation of a modiiedform illustrating the use of a plurality of springs.
  • a coiled spring 5 Upon this sleeve is mounted a coiled spring 5, with one end 5a, fastened thereto, and its other end free and normally functionless.
  • This spring which encircles the sleeve and which is here shown extending nearly the entire length of the sleeve in the space between the head and nut, acts-as a thread for the driving member.
  • the free end of the spring has a return bend forming a clutch jaw 5b, for a purpose hereinafter explained.
  • Thev driving member is here in the form ofapinion 6, adapted, when advanced longitudinally along the shaft, to mesh with the teeth of an engine member which is here the fly-wheel 7.
  • This pinion normally occupies a position intermediate the length of the spring, with the ends of the latter eX- tending beyond both ends of such pinion, and is adapted to move to the left along the spring, whereupon, a clutch jaw 6", formed on such pinion will be engaged by the jaw 5b, of the spring.
  • Fig. 3 I have shown a modified form l in which a plurality (two) of springs 8, are
  • the spring may take all the torsion load of the pinion, as in the described constructions, or. only the initial torsion load, in which case, means may be provided to take the final load.
  • modiilo f v ded form is shown in Fig. 5, in which a.
  • the spring has a comc pression action in the driving operation instead of a torsional action as in the other forms.
  • the spring may be of any desired shape in ⁇ cross section, but I preferl to make 1t polygonal, such as the rectangular form shown. Obviously, the grooves in the bore of the pinionv would be similarly shaped in' The relative groove widthV cross section. and spring diameter are such as to permit of theactions hereinbefore described.
  • the inboard type of drive With the pinion advancing inwardl toward the motor and Without any outer earing, but it is obvious that the outboard type may be readily produced by locating the motor at the opposite end of the drive, than here shown, and roviding a bearing at the outer end. oreover, it is obvious that the rotatable shaft instead of being a sleeve upon the extended armature shaft, maybe one and the same,- with such armature, or, in other words, the sleeve may be dispensed with, and the armature shaft utilized as the direct support for the spring and pinion. In such c'ase, the use of a smaller size of pinion is possible.
  • said driving member having its bore screw-threaded and directly threaded upon said spring.
