GEARING.

Specification of Letters Patent.

Patented Aug. 3, 1915.

Application filed December 16, 1912. Serial No. 736,954.

To all whom it may concern Be it known that I, VINCENT G. APPLE,

' a citizen of the United States, residing. at

Dayton, in the county of Montgomery and reduction gearing which will have an axial over all dimension substantially that of the dynamo armature alone, thereby greatly compacting the device and making it particularly adapted to mounting coaxially with the engine shaft either at the front or rear thereof.

Another object of my invention is to provide a self-starting motor of suitable construction and to mount it in front of the engine in coaxial relation therewith, with its mainv support resting in the crank lever bearing so that my improvedmotor may be quickly substituted for the usual manuallyoperable crank lever, for starting the en olIlG. V

b Other and further objects of my invention such for example as the gearing itself Will become readily apparent to persons skilled :in the art from aconsideration of the following description when taken in conjunction with. the drawings, wherein:

Figure 1 is a front elevation of an automobile, showing my motor in place; Fig. 2 is a broken-away side elevation of the front end of the vehicle; Fig. 3 is an enlarged central horizontal section of the motor; and V Fig. l is-a similar transverse section taken on line 4t of Fig. 3.

In all the views the same reference characters indicate similar parts.

In the exemplification which Ihave chosen for the clear disclosure of my invention, 10 is the bonnet or hood of an automobile, 11 is the radiator arranged in the usual manner upon the chassis or frame 12, provided with semi-elliptical springs 13, and having traction wheels .14. The internal combustion engine 15 is'mounted in the usual manneron the chassiswithmthe bonnet and. the axle .wardly-projecting poles.

16 is adapted to support the front end of the automobile upon the traction wheels. A cross sill 17 is secured to the respective bars or side frames 12, and provides a hearing 19 which is usually employed for supporting and guiding the manually-operable crank lever.

20 is the frame forming a substantial part of the housing and also the magnetic path for the field magnets 21 of the dynamo. It is provided with a perforated hub 22. which is adapted to fit neatly in the crank lever bearing 19. It is also provided with four rearwardly projecting

arms

21, 22, 23, and

24, that are secured to the cross sill 17 as by means of bolts '25 and 26. V The hub 22 of the dynamo frame is perforatedto provide rotary bearing for an elongated sleeve 27 which, in some conditions of operation, is adapted to turn in the said bearing.

28 is the engine coupling to which the motor shaft 29 is adapted to be removably connected by means of the .pin 30.. The

shaft 29 is enlarged, as at 31, to form one member of the roller clutch and, as at 32, it is provided with ball bearings33. It is also screw threaded at its outer end, as at 34, to permit the mounting of the screw threaded nuts 35 thereon for holding a member of the roller bearing 33 in place. It is also provided with a transversely positioned pin 36 as a means for turning the shaft 29,

and through the connecting coupling 28, the engine shaft, by the manually-operable crank arm or lever in usual manner. A cap 37 is removable for insertion of said lever The field magnets consist of a series of magnetic rings having eight salient in The number of poles of the machine may be varied according to the ideas of the constructor, as my invention is not limited to the number of poles that it shall contain.

Bolts or studs 38 are adapted to take through the laminae of the field magnet core and enter the main frame 20. for the purpose of securing the magnetic fieldportion to the frame. The bolts 38 project outwardly be yond the field to provide a means for securing the removable jacket or cover 39 in place. A rotatable armature 40 consists of a series of laminae of ringsheld together by screws 41 which also secure them to the rotating shell 42. Thesshell 4:2. with a plate 43,forms ahousing upon whiehthe arma-L ture core is mounted in a manner heretofore described. Within this housing is contained a pair of gear wheels 4a and that are secured together on the shaft 4:6 so that they turn as one. There is a slight difference in diameter of these wheels, the wheel .Lthaving; one or two more teeth in its circumference than the wheel 45. They are both mounted on a sleeve which has bearing on the stud 46, the latter being secured in the shell 42 and the plate l3. In the drawings I have shown three pairs of such wheels, but it is, of course, obvious that one or any convenient number of pairs may be used.

Mounted on the shaft 29 is a gear wheel 47 which meshes constantly with the gear wheel -15 and is secured to the shaft 49 by means of keys 48. The sleeve 27 is radially enlarged, as at 19, to provide a gear 50 which is constantly in mesh with thegear wheel 44. Secured to the sleeve 27 is a brake wheel 51 rotatably attached thereto by means of the keys 52-52 and the screw 53. A brake band 54: passes over the brake wheel 51 and is adapted to be tightened thereon by means of lever 55 and

cam members

56 and 57, operating on a rod 58, such parts serving to draw the two ends of the brake band together for the purpose of holding the brake wheel stationary at the time when the engine is to be started. This feature, and several others of my invention not herein claimed, are clearly disclosed and claimed in a copending application filed November 9, 1912, and identified by Serial No. 7 30,37 7

60 is a roller clutch interposed between the shaft 29 and the armature 10. A bearing ring 61 of the clutch is secured in the shell 4-2 of the armature. A ball bearing 63, one member of which is supported on the sleeve 27 andthe other member in the plate 4C3, serves as another bearing for the arma ture 40. Upon a flanged ring 6% the commutator 65 is mounted, the ring being se' cured to the shell 42 which carries the armature 40 and the commutator rotating therewith. A series, of brushes 66 bear upon the commutator segment in the usual manner.

The operation of starting the motor is as follows :The brake wheel 51 is held firmly in place by application of the brake band 54:, through the operation of the rod 58 and the lever 55 in a manner clearly understood. Then it is desired to rotate the engine shaft until the engine becomes self propelling, the motor is energized by suitable electric current, (passing through electrical conductors which for sake of clearness are not shown in the drawings), when the armature will begin to rotate,in clock-wise direction looking toward the front of the automobile. The brake wheel 51 and'the connecting sleeve 27 now being stationary, the rotation of the armature iOband' the differential gears 4 1 and 45 carried thereby indvethe shaft 29 at a speed much less than that at which the armature is rotated, and thereby the engine shaft will be rotated at a relatively low speed. When the shell 12 of armature 10 is rotating at a higher speed than that of the shaft 29, the centrifugally acting clutch 60 will not engage these two parts and therefore the connection between the armature a0 and the shaft 29 is necessarily through the train of speed-changing gearing heretofore described. \Vhen the engine becomes self propelling, the brake band 5% is released from the wheel 51 and the centrifugal effect of the rotating parts will cause the clutch 60 to engage the shaft 29 and the shell 12 of armature 40, thereby connecting the armature directly with the engine shaft. At this time the sleeve 27 will be rotated with the shaft 29, the gear wheels l-il and 15, contained in the housing provided by the shell upon which the armature is mounted, will not be rotated on their own axes, and the dynamo electric machine will be driven as a generator directly by the engine, without any intervening gearing.

Should the dynamo electric machine be out of order or for any reason should it be desirable to start the engine by the usual manually-operable crank lever, the cap 37 is removed and the crank lever is inserted on the end 34 ofthe shaft 29 until it is in engagement with the pin 36, when the engine shaft may be directly rotated by means of the crank lever and without the necessity of rotating the armature, the sleeve 27 being rotated by the instrumentality of the gearing connection. Should it be desirable at any time to resume operation of the manually-operable crank lever, the dynamo electric machine may be removed and the crank lever restored to its original position in the bearing 19 without the necessity of changing the construction of the automobile.
