ENGINE STARTER. i
Application led September 29, 1926. Serial' No. 138,558.
My invention relates to engine starting apparatus for the starting of engines such asinternal combustion engines, and more particularly but not necessarily airplane engines, and the object thereof is to provide a simple,
' efficient and reliable apparatus capable of either manual or power' operation or both andcharacterized also by the provision of simple and efficient inertia means actuated bysucli power'or manual means for the accumulation and storage of energy which is thereupon utilized by the application thereof to the engine for cranking the same. Speaking more specifically, the main object of my invention is to provide the power means, such as an electric motor, with a connecting means l' which is automatically connectable with and disconnectable from a certain part ofi' the reduction gearing which is associated with the inertia means, such as a flywheel. The construction and arrangement is such that a variable ratio between the armature of the niotoi and the fiywheel is permitted instead of the necessity of a one to one ratio. My invention also provides for the ready application to and removal from the starting apparatus of the electric motor which is disposed at an angle to such apparatus, in the present Linstance at a ninety degree angle.
In the drawing', Figure 1 is a section ot an apparatus embodying my invention; Fig. 2 an en'd view of the bell gear of the reduction gearing; and Fig. 3 a perspective of the apparatus.
My apparatus comprisesa transmission or drive having an element hereinafter designated a driving member adapted to engage and crank a. member of the engine to be started, reduction'means such as gearing, and inertia means such as a flywheel, and means for actuating such drive, gearing` and flywheel. Intl'ie present insta-nce I have shown two such actuating or driving means, to Wit: power means, such asan electric motor, and manual means including-,acrank shaft, either one of which two means may be dispensed with and i removed hfrom the apparatus if desired, though I prefer the complete apparat-us as hereinafter illustrated, that is, with both the power means and the manual means employed. For the purpose of a clearand accurate description of my invention and for convenience, I will describe my apparatus as used in connection with airplaneengines although it will be understood that the same is yfor the carrying out of my invention.
First describing the transmission .or drive,
the same is located within a. main casing 1 which is suitably supported as by being detachably connected with the crankcase 2 of the engine as by means of bolts 3, a small portion of which crankcase is illustrated. Within the casing, there rotates a driving barrel 4s and a nut 5 located and operating concentrically therewithin and operatively connected with the barrel by a yieldable driving'connection which is here in the form of a friction clutch 6. This clutch is composed of two sets of disks which arel splined respectively to the interior of the barrel and to a right-hand extension (Fig. 1) of the nut. The properpressuie for the disks is provided by a series of springs 7 located Withinthe barrel and such pressure is regulated by the adjustable ring 8 screwing in the interior of the bariel. The tlirust of these springs is against the flange 9 of nut 5 and tends to force suoli nut inwardly and consequently force p the clutch disks against the spacing ring 10 and into frictional contact with eachother.
The nut 5 is providedwith internal long lead threads 12in which is threaded a screw shaft 13 constituting the main portion of the driving member whose other principal portion'is a clutch member 14 adapted to engage a member of the engine to be started, such as the corresponding clutch member 15 forming a part of or secured to a rotatable part of the engine.l The elementli is inthe form of a disk having. clutch jaws 17 adapted to engage complementary clutch jaws 18 on the engine member and provided with a hub or sleeve portion 19 which is splined'to the outer end of the screw shaft by means of splines 20, whereby element 14 and screw shaft 13 have a `relative longitudinal movement of limited degree independent of each other.
The element 14 is' held in outward position with a yielding pressure in suitable manner as by means ot' a coil spring'- 22 Whichbears at its outer end against the bottom of sleeve 19 and at its inner end against thebottom of a socket formed in the outer end of the screw shaft. The outward movement of element 14 is limited'by the head or nut 21 on the outer or Ileft-hand end of an operating rod 23 which passes centrally through theand a plate 26 parallel therewith. This end' plate 4 has a hub 27 extendingv laterally the right in Fig. 1 and on the same there 1s loosely mounted a hub 28 of the, internal gear 29. This reduction gearing is opera.
tively connected respectively with the manual means and with the power means in the following manner:
Referring to the manual means, the same comprises Va cranking Ashaft 30 entering through one side of the casing 1 andhaving suitable bearings 31a and'32 therein. This shaft is provided with suitable means, such as the pins 33, for engagement with an ordin nary hand crank. At its inner end, the cranking shaft is provided with a bevel pinion 34 secured thereto and meshing with a corresponding bevel pinion 35 which is secured to the hub 27 of the barrel 4'.
Next referring to the inertia means, the same consists of a/lywheel 38 which hasva central hub keyed and. splined to a central shaft 43 which is here in alignment or tandem' relation with the axisof the driving member of the transmission. This shaft is provided at its left-hand end with a pinion 45 which meshes with peripheral gear teeth 46 of the bell gear 47 whose central shaft 48 is mounted within the bearing 49 of the casing 1a. This bell gear 47 is provided at one end with a pinion 50 which meshes with the internal gear 29.
Next referring to the power means or electric mot-or and its operating connections,- the electric motor 36 is removably secured by means of the bolts 36a to the upper extension of the casing 1. The armature shaft 37 of this motor is extended and provided with a screw threaded portion 38. On this extended armature shaft there is mounted the aut0.
matic engaging and disengaging', device which here comprises a c ontrol member or nut 39 and a pinion 40 which .is operatively connected with the nut 39 and controlled in itsmovements ,and ,driven thereby through the medium of a barrel 41. This barrel and nut are held in yielding extended position by means of a coiled spring 42, such barrel being splined at its upper end to the nut 39. The pinion v40 meshes with anintegral crown gear 47 on the bell gear 47 which constitutes an intermediate member of the` reduction means, and is ,adapted to rotate the latter. In addition to the main spring 42 which permits the pinion 40 to have longitudinal endwise movement in case of abutting of its teeth with the gear teeth 47 a, an additional spring 59 is provided in order to hold the device or shift in its out of mesh position.
' The rod 23 is adapted'to be manually operated by suitable connections extending through the side of the casing la, not shown.
Describing a cycle of operation and beginning with the-parts in their normal position shown in Fig. 1, except that the pinion 40 is here in its engaged position, and first describing such operation when the electric motor is employed as the starting means for the ilywheel and the drive, when the motor is energized the automatic connection between its armature shaft and the bell gear will be automatically. advanced so as to bringthe pinion 40 into mesh with the crown gear 47a and the reduction gearing as well as the flywheel will be rapidly rotated and the torque' will be transmitted to the drive or transmission including the screwshaft 13. However, this shaft will now be merely rotated. and will not be advanced as its rotation is comparatively slow because of the reduction gearing. When the flywheel rotation has reached the predetermined degree the current may or may not be cut off from the electric motor as desired by the operator but the rod is now operated by being thrust to` the left asin Fig. 1 with the result that the screw shaft 13 will be caused by such pressure and by lautomatic action between yits screw threads and those of the nut 5 to be advanced, thereby bringing the clutch jaws 17 and 18 into engagement. The engine member will thereby be rotated and the engine will be cranked. When the engine operates under its own power the driving member will be automatically disengaged through the screw action between the screw shaft 13 and the nut 5 and also the inclined formation of the clutch jaws.
Next describing a cycle of operation when themanual means is the source of power, when thecranking shaft 30 is rotated by an ordinary-hand crank the bevel gear 34vwill be rotated and thereby the bevel gear 35 and hub 37 and entire barre1`24 of the drive. At the same time the planetary gears will cause rotation of the internal gear 29 which in turn will operate the transmission gearing composed of the pinion 50, gear 47, pinion 45 and shaft 43, with the result tha't the flywheel 38'vwill be rapidly rotated. At this time the electric `motor is disconnected inasmuch as .the automatic connecting device is normally gearing will automatically disengage said device and cause it1to assume its normal position which, as stated, is a position of non-engagement with the bell gear. Still describing the manual operation, when the desired or predetermined R. P. M. of 'the flywheel is reached, the operator will actuate the rod 23 in the manner and with the result hereinbefore explained in the case of the use.of the motor as the actuating means.
The above described apparatus provides a very compact forni of electric inertia starter of the vertical form and the connecting device on the extended armature shaft serves not only as the automatic connection and disconnection between the armature and the gearing of the apparatus but furnishes an advantageous ninety degree gear drive as well and, `moreover, permits 4of a variable ratio between the armature and the flywheel.`
