ENGINE sran'riin.

Application led January 20, 1928. Serial No. 82,394,

My invention relates to engine starting apparatus forr the starting of engines, such as internal 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 and characterized also by the provision of simple and eiiicient inertia means which is actuated by such power or manual means for the accumulation and storing 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 a very compact and most eflicient apparatus, providing particularly for the greatest possible compactnessfor installation purposes and yet maintaining the greatest etiiciency in operation, especially in the case of airplane engines wherein the installation dimensions are very limited.

. In the drawings, Figure 1 is an elevation partly in section of an apparatus embodying my invention; Fig. 2 a section on the irregular section line 2-2 of Fig. 3; Figs. 3 and fi sections on the same section line of Fig. 2 marked 3-3 and 44 but looking in opposite directions as indicated by the arrows:I and Fig. 5 a section on the line 5-5 of Fig. 2.

Myapparatus comprises a transmission or drive having an element hereinafter designated a kdriving member adapted to engage a member .,of the engine to be started, reduction ineanszsuch as gearing, an inertia means such as a flywheel, and means for actuating such drive, gearing and iiywheel. `Inthe present instance, I have shown two such actuating means, to-wit power means such as an electric motor and manual means including a cranking shaft, either one of which two means may be dispensed with and removed from the apparatus if desired, although l prefer the complete apparatus as herein illustrated, that is with both the power means and the manual means employed. For the purpose of a clear and definite description of my invention and for convenience, I will describe my apparatus as used in connection with airplane engines, although-it will be understood that the same is not limited thereto in its application.

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 portlon of which ,crankcase is illustrated. Within the casing, there rotates a driving barrel 4 and a nut 5 located and operating concentrically therewithin and operatively connected with the barrel by a yieldable driving connection which is herein the form of a friction clutch 6. This clutch is com osed of two sets of disks which are spline respectively to the interior of the barrel and to a right-hand extension (Fig. 2) of the nut. The proper pressure for the disks is provided by a series of springs 7 located within the barrel and such pressure is regulated by the adjustable ring 8 screwing in the interior of the barrel. The thrust of these springs is against the flange 9 of nut 5 and tends to force such nut inwardly and consequently force the clutch disks against the spacing ring 10 and into frictional Contact with each other.y The nut 5 is provided with internal long lead threads 12 on 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 en gine to be started, such as the corresponding clutch member 1.5 forming a part of or secured to a rotatable part of the engine suoli as the crank shaft 16 thereof. The element 14 is in the 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 18 have a relative longitudinal movement of limited degree independent of each other. The element 1li is held in outward position with a yielding pressure in suitable manner as by means of a coil spring 22 which bears at its outer end against the bottom of sleeve 19 and at its inner end against the bottom of asocket 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 left-hand end of an operating rod 23 which passes centrally through the driving parts and centrally through the reduction gearing hereinafter described.

Next referring to the reduction means, the same is in the form of gearing contained within the main casing 1 by which such gearing is supported and in which it has its bearings. A stationary internal gear 24 is secured to casingl in suitable manner as by screws 25 and with the same there meshes a series of three lanetary gears 31. These gears are journa ed between the end plate 4 and a plate 26 parallel therewith. This end plate 4' has a hub 27 extending laterally to the right in Fig. 1 and on the same there is loosely mounted a hub 28 of the internal gear 29. This reduction gearing is operatively connected respectively with the manual means and with the power means in the following manner:

Referring to the manual means, the same comprises a cranking shaft 30 entering through one side of the casing 1 and having suitable bearings 31lL and 32 therein. This shaft is provided with suitable means, such as the pins 33 for engagement with an ordinary 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 power means or electric motor and its operating connections and also referring to the inertia means which is combined therewith, the electric motor 35 is removably secured by means of the screws 37 to a cover plate 1 which encloses the inertia means which is here in the form of a flywheel 38 and also the bearing extensions of the casing 1. The armature shaft 39 of the motor is operatively connected with the flywheel, and consequently tothe reduction gearing in such manner that the torque of the motor is transmitted in one direction only, that is from the motor to the fiywheel and the gearing. To this end, the armature shaft is provided with a screw threaded portion 40 on which is threaded a shell 41 whose marginal flange portion is adapted to be clamped in automatic manner against the plate 42 secured to the web of the fiywheel 38 whenever the motor is energized. This flywheel is splined to a shaft 43 and also keyed thereto by key 44. This shaft 43 also provides a bearing for the outer end of the armature shaft and for this purpose such shaft 43 has a socket at one end to receive the armature shaft. The shaft 43 is provided at one end with a pinion 45 which meshes with the gear teeth 46 of the bell shaped gear 47 whose central shaft 48 is mounted within the bearing 49 of the casing 1. This gear 47 is provided at one end with a pinion 50 which meshes with the internal gear 29.

The rod 23 is adapted to be manually operated bv suitable connections extending through the side of the casing 1. As shown in Fig. 3, a rock shaft 51 extends through a bearing 52 therein and is provided at its outer end with a collar 53 secured thereto which collar has a crank arm 54 which may be operated directly by hand or may be provided withan actuating rod 55 if desired, such rod extending to any suitable point within easy reach of the operator. The inner end of the rock shaft is provided with a crank arm 56 having a slot 57 through which the rod 23 passes and a pin 58 securing such rod to the crank arm.

Describing a cycle of operation and beginning with their parts in the normal position shown in Fig. 2 and first describing such operation when the electric motor is employed as the actuating means for the fiywheel and thc drive, when the motor is energized the clamping member 41 will be automatically advanced into clamping position with respect to the fiywheel plate 42 and rapid driving relationship thereby established between the motor and the iiywheel 38. The flywheel is thereupon rotated and likewise the torque is transmitted to the shaft 43, pinion 45, gear 47 and pinion 50 to the reduction gearing 'composed of the gear 29, planetary O'ears 31 and thence to the barrel 4 and through the clutch 6 to the nut 5 and screw shaft 13.A However. this Vscrew shaft will be merely rotated and will not be advanced as its rotation is comparatively slow because of the reduction gearing. Vhen the rotation of the flywheel has reached the predetermined degree which in practice is between fifteen thousand and twenty thousand R. P. M., the current may or may not be cut on' from the electric motor as desired by the operator and the rod 23 is operated by beine thrust to the left in Fig. 2 with the result that the screw shaft 13 will be caused by such pressure and by automatic action between its 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.

The normal position of the sleeve 19 of the clutch member 14, which forms a part of the driving member, is in contact with the nut 5, as shown in Fig. 2 and the inner movement of such sleeve is thereby limited but after the screw shaft 13 has been advanced towards the left in Fig. 2 and in case of abutment of the clutch jaws 17 and 18, such clutch member 13 will be momentarily stopped in its advance, but the screw shaft 13 will continue to advance but as soon as register between the clutch jaws 17 and 18 occurs upon the rotation of the clutch member, the spring 22 will-snap such clutch member into full engagement with the engine member. This functioning of the parts is permitted by reason of the relative longitudinal movement of the screw shaft and its clutch member 14.

Next describing a cycle of operation when the manual means is the.,source of power, when the cranking shaft 30 is rotated by an ordinary'hand crank the bevel gear 34 will be rotated and thereby the bevel gear 35 and the hub 27 and entire barrel 4 of the drive. At the same time, the planetary gears will cause rotation of the internal gear 29 which in turn will rotate the transmission gearing composed of the pinion 50, gear 47, pinion 45 and shaft 43, with the result that the flywheel 38 will be rapidly rotated. At this time, the electric motor will be disconnected inasmuch as the clamping member 41 is adapted to transmit torque in one direction only. When the desired or predetermined R. P. M. of the flywheel is reached, the operator will operate the rod 23 in the manner and with the result hereinbefore explained in the case of the use of the motor as thek actuating means.

The starting apparatus above described is very compact and eflicient, and also well balanced and the various moving parts are arranged in concentric relation and in alinement withthe rod Q3, shaft 43, and armature shaft 39 as the center. Moreover, the different units such as the drive, reduction gearing and transmission and also the manualy means are located in a single casing and the inertia means or ywheel is arranged in a supplemental casing. Furthermore, the electric motor is detachably connected to the supplemental casing and operatively connected to the apparatus therewithin in such manner that it may readily be removed from the apparatus if desired whereupon such appalratus becomes operable by manual means on y.

The casing is advantageously made in the two parts shown, one part containing the assembly of drive proper and planetary gear-` ing and the other assembly of spur gearing and flywheel. Both assemblies are individu-v ally or separately made, and are then bolted together, the operative connection being made through the meshing of the spur pinion with the internal spur gear. This construction of the casing in two such parts has resulted in considerable and material advantage over the use of a single casing.

T he particular construction and arrange..- ment of the friction clutch herein snown and described, especially the means and manner of applying the spring pressure to its clutch plates, are of importance and advantage. In the present instance, the clutch is mounted and constrained within the barrel and the spring pressure passes through the clutch plates and is resisted by the closed end of such barrel. The spring reaction is taken by the adjustment nut and endwise constrainment is effected by the inclusion of the outwardly projecting flange of the nut member. This particularly enables the use of a shorter and lighter nut, no extension thereof being required within the spring assembly, wherefore a greater section is provided for the driving member whose clutch member then occupies space heretofore occupied bv the extension of the nut, thereby allowing freater size and strength for the driving memtber.
