UNITED STATES VINCENT G. APPLE,

OF DAYTON, OHIO.

STARTING AND LIGHTING APPARATUS.

Application filed April 23, 1917.

To a]? 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 State of Ohio, have invented certain new and useful Improvements in Starting and Lighting Apparatus, of which the following is a specification.

y invention relates to starting and lighting apparatus for self-propelled vehicles.

One of the objects of my invention is gen erally to improve devices of this character and the manner of association of the various parts thereof.

more specific object of my invention is to provide an improved coupling for the shaft of a dynamo electric machine, and associate parts, whereby the armature of said machine may be directly but impositively connected to the propelling engine to increase the effect of its starting torque without impairing its operative efficiency, and by the use of which the machine maybe supported on a standard automobile without the necessity of materially changing or disturbing any of the parts of the said vehicle.

My invention furthermore relates to association of improved devices, most of which are to form subject matter of applications to be hereafter filed and more specifically described and claimed.

Other, further and more specific objects of my invention will become readily apparent to persons skilled in the art, from a consideration of the following description when taken in conjunction with the drawings, wherein:

Figure 1 isan elevation of the front end of a standard automobile, with parts in section, showing my starting and lighting system applied thereto.

Fig. 2 is an elevation of the dynamo-electric machine showing parts of the connecting mechanism and of the vehicle in section.

Fig. 3 is an end view of the dynamo-electric machine, as it appears when mounted on the vehicle.

Fig. 4 is a central longitudinal section of the dynamo-electric machine taken 1n a horizontal plane on line .l 4 of ig. 3.

' Fig. 5 is a transverse section through the removable end plate of the dynamo electric machine, taken on line 55 of Fig. 6.

Fig. 6 is a rear view of the end plate looking at the inside portion thereof.

- Specification of Letters Patent.

Patented Nov. 8, 1921. Serial u o ieasoa.

Fig. 7 is a transverse section through a part of the end plate, taken on line 77 of Fig. 8 is an end view of a portion of the armature spider and the engine shaft with the end plate removed.

In starting and lighting systems, as heretofore made, so far as I am aware, a train of speed-reducing gearing is invariably employed to connect the armature of the dynamo to the power shaft of the engine and automatically operable mechanism has been. heretofore, employed to change the speed relation of the dynamo and engine when the engine becomes the driver or vice versa. In some instances, relatively large dynamos have'been mounted on the automobiles with their armatures directly and rigidly con nected to the power shaft of the engine, but these have been cumbersome machines, necessarily, in order to produce the required initial starting torque and by reason of their low efficiency coeflicients are undesirable.

In my present invention the dynamo possesses almost unheard of efliciency; it may therefore be small, light and compact and may readily be carried on the front end of the automobile with its armature mounted yieldingly but directly on the crank shaft of the engine so as to permit some initial movement of the armature shaft before the engine shaft is moved, when the dynamo is the driver. The efficiency of an electric motor, in starting a load is greater if the armature be permitted to preliminarily move, even though the extent of movement be very small, before the load is imposed upon it. If the armature be rigidly connected to the load the effect of its torque is not maximum when the armature makes its initial movement, in its Effort to overcome the inertia of the static loa While I directly connect the armature, of a dynamo electric machine, to the power shaft of the engine I do not rigidly secure it thereto but provide a yielding connection that permits some relative movement of the armature, with reference to the power shaft, so that the armature may move at least a part of a revolution before the load is picked up. The subject matter of these preiminary statements and other features of the invention will be sufficiently pointed out 'n the drawings and more clearly referred to in the following description.

together and ho The specific structures of several of the devices will be fully described and claimed in the applications to be hereafter filed.

In the exemplification, depicted in the drawings, wherein I have shown one form my invention may take, 15 is an automobile of the standard type. 16 is an internal combustion engine. 17 is a power or crank shaftshown in Fig. 4.

The dynamo electric machine 18, for starting the engine and for charging the storage battery or batteries to be associated therewith, is secured to and supported on the cross member or beam 19. The field frame 20 of the dynamo is provided with rearwardly extending perforated lugs 21 and 22, spaced apart so that the perforations in the lugs will register with the

bolts

23 and 24 that extend through the clip-plate 25, of the machine, used to hold the cross member or beam 19 and the front spring 26.-together.

The front support 27 is secured in the trunnion block 28, which is secured to the clip plate 25 by bolts 29 and 30. The support 27 is provided with a rearward extension 31 which is semi-conical in form and which is secured to the bottom plate 32, as by rivets, or otherwise.

An armature shaft 33 is supported on ball bearings 34 and 35 within the hub 36 of the field ma net frame 20. The shaft 33 is secured to t he armature hub 50 of the spider 37 by a key 28. .The front end 39 of the shaft 33, is eccentric to the main portion and is screw threaded exteriorly, as at 40, to receive a threaded nut 41. This nut is provided with radially projecting lugs 42 and 43, for engagement withthe hand-crank starting-lever 44. The shaft 33 is provided with an integral collar 45 which engages the member 46 of the ball bearing 34, and which memberis suitably secured to the shaft. Between the member 46 and a similar member 47, is a spacing sleeve 48, to hold the ballbearing members 46 and 47 in spaced relation in proper positions with respect to similar cooperating members 49 and 49', res ectively, that are secured in the hub 36. hen the nut 41 is screwed home on the reduced threaded end 39 of the shaft 33 the hub 50,.

of the spider 37, is forced into contact with the ball bearing member 47 which in turn is brought into contact with the sleeve 48 and that with. the ball-bearing member 46 which latter is forced into contact with the collar 45, thereby tightening thesemembers ding them in spaced relation' in ,a substantial. manner. plate 51 closes the end of the hub 36 and is in substantial contactwith the hub 50 so as to prevent oil or grease from the hearing from leaking into the interior of the armature structure. Projecting rearwardly of the shaft .33. and, an integral part thereof,

A disk or vided near its outward end with a transversely extending bolt 54 and is connected to the engine shaft 17, by means of a double coil spring coupling and 56. The spring is provided with an eye 57 which surrounds one end 58 of a transversely extending bolt 17 that passes through the shaft 17. The coil spring 56 is provided with another eye 60 that surrounds the end of the bolt 54, on the opposite side. of the axis of the main and armature shaft. The coil spring 56 is provided with an eye 61 which surrounds the end 62, of the transverse bolt 17 that passes through the engine shaft 17, and at its other end is provided with another eye 63 that-surrounds the opposite end of the bolt 54. By having a double spring, each withits eyes on the opposite sides of the axis, when stress or torque is applied to the springs, the shafts 17 and 33 do not receive any stress or strain that tends to throw them out of their normal coaxial positions. The flexible connection, provided by the transmitting springs 55 and 56, will, however, permit some axial displacement of the shaft members without imposing a great deal of frictional resistance to their rotation. This flexible connection also permits the armature shaft to be rotated, to some extent, before the maximum rotating torque is transmitted from the armature shaft to the engine shaft. A fan pulley 64 is provided with an inturned hub 65, that fits over the shaft 17, and'a crowning face 66. The face of the pulley is perforated, as at 67 and 68 for insertion of the transverse pin 17' in the shaft 17. Irto the ends of the transverse pin 17 are driven tapered pins 69 and 70 to hold the major pin in place.

Upon the armature spider 37 is mounted an armature core 72 provided with the usual armature conductors 73 and 74, which extend through the core, or are included in slots therein, and which are connected to commutator segments 75 as usual in such structures.

Extending inwardly from the magnetic frame 20, is a series of magnetic poles 76, of which there maybe any desired number, (there being 12 in the structure illustrated) which are surrounded with shunt field windings 77 and preferably with a differential compound field winding 78. I

A front plate 80, forclosing the front end of the field frame, is preferably molded of insulating material, such as bakalite, or the like. The plate 80 is provided with a series ro ecting axia'lhub 88 which is preferably 90 for the commutator brushes 91-9l.

I contact that is an integral part thereof. This hub 88 is radially slotted to provide guideways 89 and The guide ways 89 and 90 are divided by a radially extending slot 92 in which the brush connecting wires 93 and 93' may freely move to compensate for the wear of the brushes which are in contact with the inner surface of the commutator 75. In the same radial plane with each of the brushes 91, 91 is a depression or a cylindrical cavity 94, each to contain an open helical spring 95 that yieldingly holds the respective brushes in contact with the inner surface 7 5' of the commutator 75.

Embedded in the plate 80, or contained in an angular groove 96' is a conducting ring The flexible conducting wires 93, one for each of the brushes 91', are connected to the ring 97, as by use of a screw 98, or the like. Another ring, 100, concentric with the ring 97. is contained in a groove 101 in the plate 80, and projecting inwardly in planes parallel to the armature axis. from the ring 100 are a series of studs 102 to each of which a flexible brush connected wire 93. is connected, as by a screw 103. A strip 103 extends from or is a part of the ring 97 and is embedded in the plate 80. This forms one terminal for the series-field of the dynamo and also one terminal for the shunt-field of the dynamo and is a terminal to which the negative end of the battery or batteries to be charged may be connected, as will be more clearly shown when the circuits are described. The connecting strip 103 is enlarged, as at 104, and is provided with an oblong perforation 105. Another strip 106 is provided with a similar terminal end 107. having an oblong perforation 108' overlying a similar perforation in the plate and is embedded therein and in connection with the binding screw108 is the terminal for the other end of the hunt field winding.

The plate- 80 is provided with an axial perforation for containing a current regulator 106. The regulator 106 is of the vibrating type operable by an electric coil 207 contained therein in connection with an eccentrically rotatable contact 208 in the end of shaft 33 and yieldingly pressed outwardly by a spring 109 for cooperation with the moved by the vibrating regulator element. I will not describein detail the operation of this regulator as that will form subject matter for another application to be filed in which it will be more specifically described and claimed.

A binding post or bolt 110 extends rear- Wardly of the dynamo and is insulatedly supported in a bracket 111 that is attached to the cross member 19. A wire or cable 112 is connected to the screw threaded bolt 110, which forms the battery connection, through the switch, as by a nut 113. The cable 112 extends to and is connected with, preferably. a controlling switch and thereby to the negative terminal of the battery. The front end of the screw threaded binding bolt 110 to which the controlling switch is connected, is connected to the binding post 108. A noninductive resistance element 115. which is adapted to be connected in series with a controller, or regulator coil 20?, is provided with two terminals, 116 and 117. The terminal 116 is connected to a binding post 108 and the terminal 117 is grounded to the frame, as at 118. A bracket 120 is supported on the front end of the dynamo, by the cap screws 84 and S5. and is intended for supporting a license plate 121, which is secured thereto by thescrews 123. 124. The bracket 120.'is provided with downwardly project ing legs 12:") and 126 which serve as means for supporting the resistance element 115.
