STARTING, GENERATING, AND IGNITION APPARATUS.

Application filed .Tune 29, 1917.

To all whom it may concern Be it known that I, lVILLIAM B. Moses, a citizen of the United States, and resident of Brookline, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Starting, Generating, and Ignition Apparatus, of which the following is a specification.

This invention relates to starting, generating and ignition apparatus for engines, and with respect to certain more specific features thereof to such apparatus forautomobile engines. It has special applicability to Ford automobiles.

One ofthe objects of the invention is to provide apparatus of the character above mentioned, which shall be simple in construction, easy to install and durable. I

Another object is to provide improved means whereby an ignition unit may be as sociated with starting and generating units in a compact organization, which latter is adapted in turn to be attached to an automobile engine Within the limited space available.

Still another object comprises the provision of reliable and inexpensive means for securing and maintaining certain parts of the apparatus assembled and in operative relations, while" nevertheless permitting their detachment in a quick and convenient manner. 4

Other objects will be in part obvious and in part pointed out hereinafter,

The invention accordingly consists in the various features of constructitm, comb-inai n o l m nts an ."1.-ang 1,1;1 1.1 s o par s which will be exemplified by the n u tion. hereinafter set forth and the scope of h application of whi h i l be indicat d in h following claims.

Fig. 6 is a right side elevational view with parts in section of the line 66 of Fig. 1.

Referring now more particularly to the drawings wherein similar reference characters refer to similar parts throughout the several views there is indicated generally at 1 a Ford engine comprising a water acketed cylinder casting 2, with inlet pipe 3, a cylinder head casting 4, Wit'h outlet pipe 5,

and a crank case 6 with extending nose or snout 7. The forward end of the cylinder block or casting 2 is formed to provide a flanged timing gear housing 8 and the present standard Ford engine has associated with this housing a cover plate, which for the purposes of this invention may be discarded.

In accordance with the rules reference is made to my co-pending application for United States Letters Patent for improvements in starting and generating apparatus, filed March 30, 1917, Serial No. 158,541

Referring now to Figs; 1 and 2, it will be noted that a supporting plate or bracket 10 issecured forwardly of the engine and trans.- versely of its crank shaft 11. The attachment is made at points around the peripheral flange of the timing gear housing by removing the before-mentioned timing gear cover plate and bolting the bracket 10 in place thereof. Other points of attachment are provided at the base of the bracket in the form of lugs having bolt holes positioned to register with standard points of attachment between a flange of the cylinder casting d a cor esponding fl ng 'th rank case- A t mingshaft 1,2 i d iv n in the usual way from a g a on the crank haf a gear twi e s z on the timing sha t The e g ars. are uita ly incased. t run in oil in th using; 8-. he bra ket 1, is p ovided Q11 on side with means or adjustably securing a motor unit 13, and on the opposite sid the bracket i provided with milar means. for adiustably wr-ina a g n rating unit .4, the mean ,con'mri ne inoth nstances, S t of bolts 1'5 two of which pa s through slots 16. in the bracke 1 an n into. th

The bracket 10 is provided with a substantially large circular opening 17, Which in assembly position, is concentric with the timing shaft 12. The bracket is also apertured at 18 concentrically with the armature shaft 19 of the generator unit, and a filler spout 20 is provided, suitably shouldered to engage the bracket 10 at the opening 19 and normally close the same. This filler spout is held in place by a spring finger 21 pivotally mounted on the bracket 10 so that it may be swung into and out of engagement with the spout, as desired.

Referring now more particularly to Figs. 1, 2 and G, the crank shaft 11 has secured thereto a pulley 23 which is formed with a wide laterally extending flange 24. To this flange are bolted web portions of a spur gear 25, this gear being preferably of as large a diameter as is possible to fit into the nose or snout '7. The pulley 23 is connected by means of a belt '26 with a fan pulley 27, whereby the engine fan is driven directly from the engine crank shaft. Means are provided in the form of an adjustable stop and a lever arm 28, which serves as a support and bearing for the fan shaft, for increasing or decreasing the tension on the belt 26.

The power transmission from the. motor unit to the crank shaft is as follows: (Figs. 1, 2 and (3:) On the end of the armature shaft 30 of the motor there is fixed a sprocket 31 which is connected by means of a chain 32 with a sprocket 33 formed on a sleeve 34, which sleeve is journaled in the bracket 10. l/Vithin the sleeve'3l, there is mounted a counter shaft 35 having a threaded portion 36 upon which is mounted for relative longitudinal movement'an unbalanced pinion 37. The shaft and sleeve 34 are yieldably connected together by means of a torsion spring 38, one end of which is connected to the sleeve 34 by a bolt 39, the other end of which is connected to the shaft 35 by a bolt 10. The transmission parts are soarranged that when the motor is energized," the sprocket 33w'ill be driven from the sprocket 31 rotating the sleeve 34 and through the yielding connection just described turning the counter-shaft 35 at a "ate of speed suit able to cause the pinion 37 to move longitudinally along the threads 3(3 until the teeth of this pinion completely engage with the teeth of the gear 25 and until the pinion is obstructed in its longitudinalmovement by a stop 41 whereupon it will turn with the counter shaft 35, rotating'the gear 25 and give the engine crank shaft the initial move ment required.

Movement of the crank shaftunder the engine fifel will zultolmitically return the pinion 37 to"no'rmal position of disengagement with the gear 25 and the motor being de'energizcd will remain at rest. Through the timing gears, however, as is well known, the timing shaft is rotated at one-half crank shaft speed. By the substitution on the timing shaft 12 of a sprocket 45 for the standard lock nut therein employed means are provided for driving through a sprocket chain 16 a smaller sprocket 17 keyed to the arn'lature shaft 19 of the generator unit, whereby the generator armature may be rotated continuously from the engine at comparatively high proportionate speeds. The generator unit 11 isformed with a substantially wide end cap member 18 recessed at 49 to receive a spirally toothed ignition shaft driving gear 50, this gear being keyed to the generator armature shaft 19 adjacent the sprocket 17. The end cap 18 provides a journal 51 for the main vertical shaft. on an ignition device 52. As seen in Fig. 3, this shaft is provided with a spirally toothed gear 53 which meshes with the gear 50, providing the driving connection, whereby the main shaft of the ignition device is driven in direct proportion to the armature shaft, and likewise, therefore, to the engine shaft. It will be noted that the removable filler spout 20 is adapted for attachment opposite the end of the armature shaft, which provides for lubrication of the ignition and generating power transmitting devices by the oil introduced for cylinder lubricating purposes. Furthermore, the spout being removable permits access to the end of the generator armature shaft. for purposes of assembly or removal of the parts. The innor faces of the bracket 10 serve as conduits for the lubricant introduced through the filler spout and complete the oil passage between the ,filler spout and the engine casing, a suitable outlet being provided at the rear of the bracket where the same attaches to the timing gear housing of the cylinder casting.

Tn assembling the apparatus, the standard Ford crank shaft pulley may be removed "andthe combined pulley and gear 23 and respectively, substituted. The original commutator, roller arm, timing gear. lock nut and'timing gear housing cover may be removed and the bracket 10 secured in position, after which the large sprocket 15 is screwed on to the threaded end of the timing shaft 12 in place of the standard lock nut. Apcover plate oosuitably shouldered is then fitted into the aperture 17 in the front of the bracket and thisplate is providednyith packing adapted to fit'tightly; around a hub 56 tirttlre large sprocket' The original rel-a commutator parts are then restored to with thespring finger 21. The commutator" cap 57 bears against the outer face of the essee].

cover plate 55 and in turn seals the same in quick detachable relation with the bracket 10.

The easy accessibility of the working transmission parts is one of the features of the present invention. By swinging the fingers 58 and 21 out of engaging positions with their respective arts, the filler spout 20, commutator cap 15 Ford roller carrying armand cover plate 55 may be quickly removed from the assembly giving free access to the chain and sprocket connections of the generator drive. If it is desired to remove the generator unit for any reason it is only necessary to remove the filler spout and the sprocket 47 may be withdrawn from the generator armature shaft from the front of the bracket through the opening normally closed by this spout. The generator and ignition units may then be removed by freeing the bolts 15 from the end cap 48. B this means it is not necessary to open the sprocket chain46 or remove same from either one of its sprockets.

It should be noted that the various parts described have multiple functions whereby the exceptional compactness is obtained and the application of power confined to points of exceptional reinforcement against lateral stress. The bracket 10 not only performs a supporting function but is hollow and shaped to serve in the oil conduit from the filler spout to the lower crank casing. And so, as well, does the bracket serve as a housing forthetransmission parts, enabling them to partake of the cylinder lubricant passed through from time to time and preventing the ingress of dirt. Further, the bracket serves to incase the timing gears, and disregarding the motor side for the moment becomes, in short, a cover'plate for the timing gear housing of the engine casting, with but a short lateral extension to receive the generator. This extension comprises a hollow chamber with an opening at the rear to communicate with the coupling or end-cap member and an opening at the forward side to which is fitted the filler spout. Obviously as far as the oil filling features are concerned, the dynamo might be attached directly to the rear wall of the bracket without including the coupling or ignition member.

It will be found that the member 48 performs several services. It carries the igniter shaft properly journaled, provides for attachment to the rear wall of the bracket and to a forward part of the dynamo frame. It provides a housing for the driving connection-between the armature shaft and the igniter which housing is in communication with the oil conduit formed by the bracket permitting the passage of oil to said housing for lubrication of the driving connection. The mounting of the igniter, as shown herein, at a point in close proximity to the point of attachment of the generator unit to the bracket, has an important effect in minimizing vibration.

As many changes could be made in the above construction and as many apparently widely difi'erent embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter set forth in the foregoing description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
