Definitions

  • My invention relates to a starter for an engine such as an internal combustion engine, and pertains more particularly to the drive or transmission thereof for automatically connecting the starting motor or other source of power to a member or part of the engine to be started and for thereafter transmitting the power thereto for the startlng of such engine.
  • My invention is embodied in thepresent instance in a structure of the type known as the Eclipse-Bendix type of drive such as exemplified by patents heretofore issued to Vincent Bendix, for example Patent No. 1,125,935, dated January 26, i915, but my invention is not limited to any specific type of starter as I contem late using the same wherever applicable. and definite description of my invention I have chosen to describe it in connection with said type of drive which is characterized by the employment of a rotatable member, such as a screw shaft, and a driving member, such as a pinion mounted thereon for longitudinal movement thereof and rotary movement therewith and adapted to be con nected either directly or indirectly with the engine member.
  • a rotatable member such as a screw shaft
  • a driving member such as a pinion mounted thereon for longitudinal movement thereof and rotary movement therewith and adapted to be con nected either directly or indirectly with the engine member.
  • the driving member is the pinion itself and the same is adapted to be connected directly with the engine member.
  • My invention re-' lates more particularly to the construction of this pinion whether the same is directly mounted upon said'screw shaft or operated directly or indirectly thereby, and the object thereof is to provide simple and efficient means for facilitating the meshing of the pinion with the engine member such as the fly wheel.
  • I accomplish this object by providing such pinion with a pilot member having teeth similar to the pinion itself and capable of movement with respect thereto and adapted not Specification of Letters Patent.

  • Fig. 10 a detail view of a modified form of screw shaft which may be used.
  • My invention relates to the pinion'structure and the same is not the ordinary plain pinion but a special. form of construction consisting of a pinion proper 6 and a pilot a member 7.
  • the pinion such member is not screw-threaded upon thescrew shaft but is merelymounted upon the top faces of the threads of the screw shaft, the borejof such pilot member being slightly greater in diameter than the 'full diameter of the'screw-threaded portionof the screw shaft including the screw threads.
  • the pilot member is carried by the pinion pro er and is held projected therefrom slig tly in advance of its right-hand face in a yielding manner, and the same also has an interlocking-connection therewith.
  • a plurality of coiled springs 9, here four in numin the pinion ber, are anchored at their opposite ends in the bottom of socketst and 7 respectively proper and ilot member, as shown in detai in Fig. 4. hese springs are of such length. that the pilot member will be held projecteda' certain'distance in front of the pinion proper, as indicated by the clearance space 10 in Fig. 4, and said sockets have beveled mouths 6 and 7 respectively in order to accommodate the spring when the pilot member is moved rotarily with respect to the pinion as hereinafter explained.
  • the pinion and pilot member have an interlocking connection which, as shown, is in the form of a tongue-andgroove connection, the grooves 6 being here .1n the pinion and the tongues 7 in the pilot member.
  • the grooves are of greater width than the tongues which normally occupy a central position in the grooves as shown in Fig. 1 so that the pilot member may have a slight yielding movement rotarily before coming into contact with or disturbing the position of the pinion.
  • the pilot member has the forward or engaging end of its teeth properly chamfered in order to assist'in the operation of meshin with the fly wheel teeth. As shown in ig. 1 for instance these teeth have a single chamfer, but owing to the fact that the pilot member is capable of oscillating in either direction, a double chamfer, that is-a chamfer on both sides'of the teeth may be employed.
  • the pilot member is capable of oscillating in either direction, a double chamfer, that is-a chamfer on both sides'of the
  • the ilot member will be first presented to the y wheel teeth and in case of perfect register between the teeth thereof (and consequently of the pinion teeth) and the teeth of the fly wheel, the pinion and its' pilot .member will be continued to be advanced without any interruption or change in their relative positions until the pilot member contacts the stop nut '11 whereupon the pinion will advance until it comes into contact with its pilot member and will thereupon partake of the rotary movement of the screw shaft and rotate the fly wheel.
  • Fi 5 and 6 I-have "shown a modified form of construction in'which the pinion When the -en ine starts on its own power the pinion wil be automaticall nally into contact with such pilot member.
  • Figs. 7 and 8 I have shown another modified form of construction according to which the pilot member 13 instead of being loosely mounted on the screw shaft is screwthreaded thereon, but provision is made for a yielding longitudinal movement on the screw shaft and toward the pinion and against the tension of the springs 14.
  • the pilot member has screw-threads 13 which are much less in width than the distance between the screw-threads 2 of the screw shaft, with the result that the pilot member is capable of said longitudinal movement toward and away from the pinion and against'the tension of the springs 14 which normally hold ,the pilot-threadsT18 he mode of operation is substantially the same as above described except that in.the driving operation the teeth of the pilot member take some of the load, depending upon the amount of space between the threads of the screw shaft and those of the pilot member relative to the space between the pinion and the pilot member.
  • Fig. 9 I have shown a modified form of construction in which the pinion 15 has a forward sleeve extension 16 on which the pilot member 17 is mounted to slide longitudinally and also rotarily. This member is held projected from the pinion by springs 18 but retained thereon in suitable manner as by the split ring 19 engaging in a peripheral groove in such sleeve extension.
  • this construction embodies the feature of a pinion stop independent of the pilot member, in as much as the sleeve extension of the pinion will come into contact with the stop nut 11, it being understood that this pinion is mounted on a screw shaft such as shaft 2. In thisway the pilot member is relieved of all load.
