scription of'my invention and for conven-* lust-rated. of which Figs. 1 and 2 show the present preferredand recommended form, although .it will be understood that the same is not limited thereto but may partake of difierent'forms and arrangements of embodiment.- f p My apparatus com rises a drive or trans-- mission proper inclu ing a drivin member adapted to'engage and crank a mem er of the' 4 engine to be started, gearing which'is speed multiplying gearing or reduction gearin according to whichever end thereof is the riV.-" er, an inertia means or flywheel, and power means and manual means for actuating the flywheel through such gearing.

-First describing the drive proper as herein illustrated, the same is located within a main casing 1 which is suitably supported. as by being detachably' connected with the crankcase 2 of the en ine in suitable manner as by means of the ho ts 3, a-small portion of which crankcase is illustrated. Within the casing there rotates a driving barrel 4 and a control member or nut 5 located and operating concentrically therein and operatively connected with the' barrel by a yielding driving connection which is here in the form of a friction clutch 6. This clutch is composed of two sets of disks which are splined respectively to the interior of the barrel and to a right-hand extension of the nut, Fig, 1. The proper pressure for the disk is provided by a series of springs 7, located within the barrel and suchpressure is regulated by an adjustable ring 8 screwin into the interior of the barrel at the left-hand end thereof. The thrust of these springs is a ainst the flange 9 of the nut and tends to orce such nut inwardly and consequently force the clutch disks against the spacing ring 10 and into frictional contact with each other.

The nut 5 has internal long lead threadsin which isthreaded a screw shaft 11 concorresponding clutch member 13 which may form a partof or be secured to any rotatable part of the engine such as the crank shaft 14 thereof. The member 12 has clutch jaws 15 adapted to engage complementary clutch jaws 16 on the engine member, which jaws are adapted to become automatically dlsengaged because of their inclination, when the engine starts on its own power; The clutch member 12 is splined to the outer end of the screw shaft 11 whereby such parts have a relative longitudinal movement of limited degree independent of each other. 1

The clutch member 12 is held in outward position and kept in place upon the shaft 11 with a yieldin pressure in suitable manner as by means 0 a coil spring 17 which bears at its outer end a ainst the bottom of the sleeve portion 18 or the driving member and at its inner end against the bottom of-a socket 19 formed in the-outer end of a screw shaft. The interior of this sleeve 18 has splines 20 whereby thesame is splined to the shaft 11 as above stated. I The outward movement of the member 12 is limited by a nut 21 screwing onto the outer or left-hand end of an operatin rod 22 which passes centrally through the riving member and also throughthe reduction gearin and starting motor ashereinafter explained. In the present instance this rod is manually operated and connected at its outer end which is extraneous to the motor with an operating link 23 which extends to some convenient location whereby it may be operated by the operator-either directly or through other connections, not shown.

The driving barrel 4 has an end or bottom portion 24 which has a central bore to drivingly receive the smaller diameter. portion 25 of a hub of a pinion hereinafterdescribed,

through which hub the rod 22 passes freely and on which certain members of the gearing are mounted. Upon such end portion 24 there is mounted a series of planetary pinions 26 by means of a ring 27 and studs 28. These pinions mesh respectively with a stationary internal gear 29 secured to the casing 1 in suitable manner as by means of screws 30 and with a central pinion 31 here formed on the hub itself of a large gear 32 which is mounted to rotate freely upon the hub 25 through i the medium of the bearings 33.

The gearing further comprises a pinion 34 here formed on the hub itself of a large gear 35 and meshing with the gear 32. This gear 35 in turn is operatively connected with a pinion 36 formed as .a part of the inertia means or flywheel.

The gearing described'is located in a casing 1 which is secured to the main casing in suitable manner as by means of the screws 37, and in opposite walls of such casing 1" are mounted the bearings 38 and 39 for the shaft 40 on which the gear 35 is mounted either e ea? which fits in the upper end of the casin 1 The flywheel is composed of a rim 42 aving a predetermined or desired mass or weight, a web 43 and a central extending hub 44: which is mounted in the bearings.4546

in the casing 1 and extension 1 and which is drivingly secured vin suitable manner as by key d7 to the hub of the pinion 36.

Next describing the manually operated means, the same comprises a cranking shaft 48 rotatably mounted in one wall of still another casing l which'is secured to the casing 1 in suitable manner as by means of the screws 49. The outer end of this cranking shaft is provided with' suitable pins 50 which are adapted to be engaged by an ordinary hand crank applied thereto and rotatedby the operator. The inner end of this cranking shaft is provided within the casing 1 with a bevel gear 51 which meshes with a corresponding bevel gear 52 the larger diameter portion 53 of whose hub is mounted in the bearings 54 in one of the walls of the casingl and held in position by the lockhut 55. Referring to the startin motor which is indicated generally at 56 t e same is detachably secured to the casing 1 in suitable manner as by means of the screws 57. This motor which is of the low speed high torque type and preferably series wound has an armature shaft 58 having a central bore through which the rod 22 loosely passes and being extended and preferably supported towards its outer end in bearings 59"which are located in a cylindrical extension 60 secured to the frame of the motor by the screws "61.

The automatic operating connections between the motor and the gearing-here comprise a nut 62 which is threaded upon'the threads 63 at the outer end of the armature shaft Wherellf) by when such shaft is rotated this nut will automatically move or advance. outwardly towards the left. This nut is provided with clutch jaws 64 adapted to engage corresponding clutch jaws 65 formed on the inner or right-hand face of the bevel pinion 52. The described advance movement of the nut 62 is against the tension of a light spring 66 bearing thereagainst, and agalnst a spring abutrapidly through the gearing in Vance outwardly to the left and engage the que of the armaturebevel inion 52. 'The tor will t 'ereupon be transmitted to thepinion I 52, plate 24, planetary gearinmandgear 32 and thence'to'the gear 35 and finall to the flywheel 42 through the pinion 36. T 1e start. ing motor is a slow speed high torque motor, as stated, and the-torque being transmitted adireet-ion to the flywheel such gearing will bespeed multiplying gearing and. the speed of the motor will thereby be multiplied and the flywheel will I be rapidly rotated. "When the desired may or may not be interrupted as desired,

but the rod 22 is moved longitudinally to the the operator thereby causing the left by screw shaft 11 and its clutch member 12 to be likewise moved -tothe left through such longitudinal movement and the screw threaded connectlon of such shaft with the nut 5,

whereupon the clutch jaws and '16 will en "age and the engine will be rotated and therey cranked by the stored up energy of therotatmg flywheel 42. This 1 energy is transmitted through the gearing nowacting as reduction gearing,'that is, through the gearing an such and gears and 32 to the planetary thenceto the driving barrel 4 and from barrel through the clutch 6 to the nut 5 screw shaftlland clutch member 12 and fi- I nall y When the engine to the engine as described. The screw threaded connection between mg operation. I

starts on its power, the

. driving member 11.12 will be automaticall 13 and its nut'5'; It is obvious that the motor operation-but disengaged from the engine member, hot by the action of the inclined jaws 15-16 and the screw thread connection between the shaft may be kept energized during the starting the desired speed of rotation ofthe flywheel Fl no is reached and rod 22 has been. actuated. When the motor is thus de-energi ze'd and the gearing becomes the driver the nut 62 is automatically' disconnected and. restored toflthe normal position shown assistedby the light spring 66.- I

When the manualmeans is employed, the operator cranks the'shaft 48 whereupon the pinion 52 will be rotated together with the gearing and the flywheel in the same manner as performed by the starting motor. When the flywheelhas reached the desired or predetermined speed the apparatus is operatet in the's'ame manner as already explained. I It will be noted that during the manual operation the starting motor isdisconnected and the only load to 'the hand cranking is the load of rotating the flywheel.

speed of rotation of the. I flywheel is" attained the current to'the motor the shaft 11 and its nut 5 assures full engagement of theclutch 'aws and maintains thesa'me during the 'driv-.

in practice it is sufficient .to cutoff the current supply to the motor as soon as "In I'have'shownthe'modified forin of construction which is characterized by the of-Fi 's. 1' and 2.

. Referring to Fig.

same reference numerals. In this modification, the clutch jaw instead of being upon or a part of the gear 52 is-connectcdwith or as herein shown forms apart of ashaft 68 and to the ,casing l also serves as the'mounting for the manually arrangement of the electric motor in a poslthe actuation desired, the motor; itself may be made to-run in a direction opposite to that of the motor 3, the parts corresponding to those shown 1n Figs. 1 and 2-are given the has its'bearings in a casing 1 which is secured I I and to the motor frame and. I

operated means, 'At' the inner .end of this shaft 68 there is drivingly secured a bevel 52, this shaft 68, andthe cranking shaft 48 being in axial al ine ment and meshing with thelgear 52 at diametrically opposite points.

In .this. construction,

pinion 69 which meshes with the bevel gearthe manually operated.-

'rod 22 extends between-the ends of the two if "1. The mode of operation is the same as that her 62 does not clutch the gear 52,but becomes automatically connected with the shaft 68 through whose'rotation the bevel pinion 69 and consequently the remainder of the mechanism are operated.

Referring to the modification illustrated in .Fig. 4, a common cranking shaft. is employed for a smgle bevel pinion which meshes common cranking shaft being in axial alinement. Accord1ng to thls construct1on, the

common shaft is a shaft 70 having itsybea rshafts 48 and 68 andextraneous of the casing I with the gear 52,'the motor armature and the I manual cranking shaft which now becomes .a.

above described with the exception of course that the automatically operating clutch mcm- 'ings in a casing 1 and having intermediate its length and drivingly secured thereto a bevel pinion71 One'end of this shaft extends extraneous of this casing for the application of a hand crank as in Figsgl, 2 and 3 a clutch member '72 sim as or provided with and adapted to ilar to the clutch member 65 while the other end of such shaft is formed be drivingl'y connected with a clutch member" I 1 such as the member 62 and driven bythe motor as illustrated in Fig. 3.. The manually operated rod 22' is obviously curved around such cranking shaft as indicated in the drawing; The mode of operation is the same as that above described.

For practical purposes, the electric motor may have a normal end point of say 100 R. P. M. prior to engine engagement and as the gear ratio here shown is about 150 to 1, it follows that the flywheel will be accelerated to a speed of 15,000 R. P. M. If a higher flywheel speed is desired, the same can "be obtained byeither increasing the gear ratio or modifying the motor to operate at a higher normal speed. Inasmuch as the motor is series Wound and startsunder no load, its initial acceleration is considerable which, assisted by the inertia of the nut 62, causes engagement with the gear 52.

It will be understood that the gearing above described is speed multiplying means when.

the torque is transmitted in a direction towards the flywheel and that it is speed reduc- 4 ing means when the torque is transmitted from the flywheel or inertia meansto the driving member and thence to the engine,'but for convenience, I Will refer to such means in the claims as speed multiplying means.

By means of my apparatus I am enabled to employ a low speed high torque motor and to utilize the same gearing to multiply the speed of rotation that is utilized by the manual means.

In the present apparatus, there are employed certain constructions and features (such as the drive proper and the manual control of its driving member, the speed multiplying mechanism for the most part and the actuation by either or both manual means or power means), which are described and claimed in certain of my prior patent applications, such as those filed on September 28, 1925, Serial No. 59,113 and 59,114, and therefore I do not claim herein anything in common with such applications but the particular invention defined by the claims herein.
