LANSING,'OF MONTCLAIR, 1\`I'EW T1]RSEY,v ASSIGNOR TO ECLIPSE MACHINE COMPANY, OF ELMIRA., NEW YORK,E A CORPORATION OF NEW YORK ENGINE STARTER Application filed September My invention relates to engine starting apparatus for 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, efiicient and reliable apparatus for either manual or power operation or both and characterized by the provision of inertia means which are actuated by such power means 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, and further characterized by the provision of means for disconnecting the power means such as an electric motor when the manual means. are operated and still further characterized in the construction hereinafter described by the yprovision of novel and efficient clutch mechanism, whereby the inertia means is operatively connected at the will of the operator with a member of the engine to be started and the energy/of such inertia means is transmitted to such engine member and the engine is thereby cranked.

proper and reduction gearing. First describing the drive proper the same is located within the main casing 1 which is suitably supported as by being detachably connected with the crank case 2 of the engine, a small portion of which is illustrated. Within a bushing 3 in the casing there rotates a driving barrel 4 and a shell 5 concentrically arranged therewithin and providing a considerable annular space between them to receive a yieldable driving connection which is here in the form of a friction clutch 6. This clutch is composed oftwo sets of clutch plates or disks which are splined respectively to the interior of the barrel and the exterior of the shell. The proper pressure for the disks is provided by a series of springs 7 located in such annular space and such pressure is regulated by the adjustable nut 8 screwing onto the outer end of the shell. The uthrust of these springs tends to force the shell outwardly whereby the ring 9 clamps the disks -together by forcing them against the ring 10 which bears against the annular internal flange 11 within the shell.

The shell 5 is provided with internal long lead threads 12 (Figs. 2 and 7 on which is threaded'a screw shaft 13 which constitutes the main or body portion of the driving member whose other principal portion is a clutch member 14 which is adapted to engage a member of the engine to be started such as the corresponding clutch element 15 forming a part of orgsecured to a rotatable part of the engine such as the crank shaft 16. thereof. The clutch element 14 is in the form of a disk having clutch jaws 17'adapted toengage the complementary clutch jaws 18 on the engine member` and provided with a hub or sleeve portion 19/ vwhich has a bearing t within the shell 5 and which has internal longitudinal splines and grooves 20 cooperating with corresponding splines and grooves 2.1 on the outer end portion of the exterior of the screw shaft 13,

' suitable manner as by means of a coiled spring 22 which bears at its outer end against the bottom of the sleeve 19 and at its inner end lagainst the bottom of a socket formed in the outer end of the screw shaft. The outward movement of the clutch element 14 is limited by the head of a rod 23 which passes centrally through'the driving member parts and centrally through the main supporting shaft 24 of the reduction gearing, such rod being a manually operated rod terminating in a handle 25 at a point exterior of the apparatus and in the present instance being located adjacent the exterior of the casing of the manually operated means. In the present instance, for assembly purposes, this rod is made in two sections screwing together intermediate the length of the rod and provided at the point of juncture with a flange 26 bearing against the inner end of the screw shaft in order to limit the movement of the rod to the left with respect to the screw shaft, Fig; 2. The inner end of the screw shaft is provided with two nuts 27 the one nearest the end of the screw shaft being a lock nut and the other providing an abutment for .the outward movement of the screw shaft against Ithe internal shoulder 28 within the shell-5.

Next' referring to the reduction gearing the same is contained within the main casing l and the cover plate 1a by which such gearing is supported and in which it has its bearings. A main stationary internal gear 29 is secured by screws 30 to the casing 1 and with the same meshes a series of three planetary gears 31 which are journaled between two

parallel plates

32 and 33. These plates are spaced apart by suitable lugs 34 on adjacent facesz of these two plates and the same are held together by screws 35. The inner plate 33 is connected with the driving barrel 4 in suitable manner and in the present instance the same is splined to the inner end thereof .through the splines 36 and grooves 37 cooperating with corresponding splines and grooves on the outer face of the plate 33..

This plate 33 has a hub provided with longitudmal grooves-adapted to receive the oppovsitely extending projections or pins 38 at the left hand end of the shaft 24 (Fig. 2)

- whereby such shaft and' plate are detachablv connected and the shaft is adapted to drive the plate and its attached gearing.

The pinions 31 mesh with a central pinion 39 which as shown and by preference is formed as a part of the hub' 40of a gear 41 mounted to rotate freely upon the shaft '24 through the bushing 42. This gear 41 meshes with a pinion 43 which as shown and by preference is formed upon the hub 44 of a secured by screws 51 to the casing plate 1.

In additionto this pinion 49 the manual means consists of a cranking shaft 52 extending extraneous of the casing 50 and thereat provided with suitable means as the pins 53 for engagement with an ordinary hand crank. This cranking shaft 52 is journaled in ball bearings 54 Within the casing 5() andy the same is held in proper position longitudinally by the nut 55 and collar 56. The shaft 52 is provided at its inner end withv a beveled pinion 57 meshing with the corresponding pinion 49.

Describing the inertia means the same comprises a fly wheel and operating connections with the beveled gear 45 and with the prime mover which is here an electric motor, such inertia means being contained within and supported by a casing 58 which is secured to the main casing 1 in suitable manner as by the screws 59. The fly wheel comprises a riml 60 having the predetermined. or desired mass or weight, a web 61 and a hub 62. This hub is drivingly secured as by 3fly wheel is held in proper position on 4the shaft 63 and with respect to its bearings by the nut 65. The outer surface of the hub is formed as one of the members 66 of a one-way or over-running clutch, the other rov tatable member of which 67 is formed on the inner circumference of a shell 68 secured in suitable manner as by splining to the extended armature shaft 69 of an electric motor 70 and held in place thereon by the nut 71. The outer end of the armature shaft extends downwardly into the sleeve and is received by the socket 72 in the upper end of the shaft 63 actingas a bearing for such lower end of the armature shaft. The clutch may be of any desired type but in the present instance it is of the friction ball or roller type in which spring pressed balls or rollers 73 located in recesses in the clutch element 66 are employed to frictionally engage and grip the inner cir-A ning clutch which is adapted to transmit torque in one direction only, and in the present instance from the electric motor to the shaft 63 and to the succeeding elements in the train of the transmission. The fly wheel is consequently rapidly rotated and when its R. P. M. reaches a predetermined ligure such as in practice from fifteen thousand to twenty thousand the current may if desired be switched off from the electric motor and thereupon the rod 23 is manually moved inwardly, that is to the left in Fig.l 2, and the screw shaft and its clutch element 14 are moved longitudinally and such clutch element is thereby advanced and brought into engagement with the other clutch element 15-and the engine is thereby cranked in view of the fact that the clutch element 14 is being rotated through the drive or transmission by means of theiiywheel, andsuch rotation will continue so long as there is sufcient energy left in the Hy wheel for that urpose. Describing transmission of torque from the shaft 63 through the reduction gearing and the drive proper, the rotation of the shaft 63 will rotate the gears 45 and 41 whereupon the central pinion 39 will be rotated and consequently the planetary pinions 31. As a result these latter pinions by reason of their meshing with the internal stationary gear 29 will cause the entire frame or cage by which they are supported consisting of the

plates

32 and 33 to be rotated. Inasmuch as the plate 33 is drivingly connected to the` driving barrel 4 the latter willl be rotated and consequently the shell ornut 5 will be rotated through the medium of the friction clutch 6. Although the screw shaft 13 is screw threaded to the now revolving shell or nut 5 it will. not advance longitudinally but will rotate with such shell and consequently the clutch element 14 will .likewise be rotatedj However, at this time such clutch element is in normal position that is out of engagement with the engine clutch element 15, but when the rod 23 is moved to the left (Fig. 2) as hereinbefore explained the screw shaft will be moved longitudinally whereupon said clutch elements will be brought into engagement and the torque or accumulated energy of the inertia means or fly wheel will be transmitted to the-engine to crank the same.

When the engine starts on its own power the excess speed 0f rotation of the engine and its clutch element 15 will cause the screw shaft and its clutch element 14 to be retracted by the screw action between the screw shaft and its sleeve or nut 5 and thereby to become disengaged from the engine in automatic manner.

Next describing the manual means as the source of energy a hand crank is applied to the cranking shaft 52 and rotated by the operator first slowly until the fly-wheel gathers screw shaft.

speed and thereupon more rapidly until the desired or predetermined R. P. M. of the fly wheel is reached. In this operation the torque is transmitted from the cranking shaft 52 through the

pinions

57 and 49 to the shaft 24 and thence through the cage or frame of the planetary pinions 31 to the

pinions

31 and 39 and gear 45 and thence to the shaft 63 and finally to the fly-wheel 60. In this operation owing to the presence of the oneway clutch the torque is not transmitted to the electric motor but such motor is disconnected from the shaft 63 and it will thereupon remain idle. Ihis is of advantage inasmuch as the considerable load occasioned by the pressure of the brushes74 upon the commutator 75 is removed from the cranking operation. This load is considerable owing to the fact that it is multiplied many times through the gearing described. The fly-wheel having nowbeen rotated to the proper speed` the rod 23 is operated and the engine cranked in the same manner as above explained.

The engagement between the

clutch elements

14 and 15 is a yielding one owing to the provision of relative longitudinal Inovement between the clutch element 14 and the In case the clutch jaws do notregister at the timeof such advanced movement of the j aws 17 the clutch element 14 will be momentarily stopped but the screw shaft will continue its longitudinal movement and owing to such stoppage the screw shaft will rotate slightly and thereupon bring the

clutch jaws

17 and 18 into register whereupon the spring 22 will snap the jaws 17 into engagement with the jaws 18.

The construction is such that the-rotation of the clutch element 14 is in a direction the reverse of that of the cranking rotation, that is the direction of rotation of the nut 5, and consequently the actual engaging speed of the clutch element 14 is a resultant speed which is the difference between the forwarc speed and this backward speed of the clutch element 14, therefore, the engagement between the clutch jaws is at a low speed which is of considerable advantage.

In case of back lire ofthe engine or of any undue\resistance of the engine during cranking operation the friction clutch 6 will slip and the parts of the apparatus will thereby be protected.

In the event that after the engine has once started but the explosions should then cease after the clutch `jaws have become auto` matically disengaged, the rod 23 may be again operated to engage the clutch jaws for a second cranking operation, there being suicient energy still available in the flywheel for another cranking operation inas` much as in practice a number of successive If, upon cranking, the engine should fail to start because of no explosions and the engine by first withdrawing the jaws 17 `from mesh with jaws 18, because of relative movement of the clutch element 14 with respect to the yscrew shaft l'against the tension of spring 22, and then when the body of such clutch element ab-uts the left hand end of the screw shaft, the entire screw shaft and clutch element are withdrawn to full extent to the right, that is to normal position.
