END PLATE'FOR COMBINED IGNITING AND LIGHTING GENERATORS.

Application filed June 30, 1915.

To all whom it'may "concern:

Be it known that 1, JAMES M. W ILSON, a citizen of the United States, residing at Newark, in the county of Essex and State of New" Jersey, have invented certain new and usefulImprovements in End Plates for Combined Igniting and Lighting Generators, of which the following is a specification.

My invention relates toimprovements in generators used for both ignition work and lighting,v in which the ignition current is generated within the machine and deliver d direct to the spark plugs or ignition deyices of an internal combustion engine and the current for lighting the lamps and charging the battery of the vehicle to which the generator is attached is generated in the same machines, but from a separate armature- My present invention is directed to ways and means for mounting the igniting and lighting armatures within the same magnetic field frame, so that'in case of necessity, the armatures may be readily removed for the purpose of inspection and repair.

In order to accomplish this purpose, I have provided a combination of end plates which-are adapted to be quickly attached or detached from the field frame. The end plates serve to carry the bearing supports for the two arniatures and as housing for the electrical connectors and mechanical devices used in connection with the operation of the entire structure.

In my application, Serial Number 832539, filed April 17', 1914, patented March 20, 1917, Patent No. 1,219,518, I have shown a sectional view of my igniting and lighting generator having the end plates which constitute the subject of this application.

Referring now particularly to the draw ings, Figure 1 is a longitudinal sectional elevation of my combined igniting and lighting generator diagrammatically illustrated in Fig. 7, showing, however, only the end plates in section.

Fig. 2 is a left hand end view of Fig. 1 with the cover plates removed from the plates which house the circuit interrupters for both armatures.

Fig. 3 is an end view of the righthand end plate of Fig. 1.

ing for the lighting armature slightly withdrawn from the end plate.

Fig. 5 is an end view of the two larger end plates of the left sideof Fig. 1.

Fig. 6 is a side elevation of Fig. 5 but with the outer end plate slightly withdrawn from the inner end plate.

Fig. 7 is a. diagrainmatical illustration of the circuit arrangement used in one form of my invention and is the same as Fig. 7 of my application, Serial No. 832539 above referred to.

Fig. 8 is an end view of an auxiliary platemounted on the outer plate of Fig. 6 and carrying the contact switching members shown in Fig. 7.

Fig. 9 is a section on the line AB of Fig. 8.

Fig. 10 is a modified form of an auxiliary plate carrying switch members.

Referring now particularly to the drawings in which like numerals refer to corresponding parts in the various views, 1 is a base of non-magnetic material to which is attached in any suitable manner, pole pieces 2 and 3. These pole pieces have extensions 52 and 1- to which are attached by any suitable means, such as screw, pole pieces 5 and 6. Bridging the extensions 52 and i is a yoke 7 carrying a coil 8. Mounted on the pole pieces 5 and 6 are held coils 9 and 10. Between the pole pieces 2 and 3 and mounted on suitable bearings 11 and 12 (shown in- Fig. 1) is a high tension armature 16 of a type particularly adapted for firing a two cylinder engine in which the cylinders are placed at an angle- The current in the primary winding of the high tension armature 16 passes through the circuit breaker 22 and is interrupted at the proper intervals by means of the cams 13 and 14 located within the cam holder which is mounted on one of the end plates 34. The high tension. current is taken off the spool 15 by brushes inthe usual manner and is conducted to the spark plugs in the usual manner.

Mounted above the ignition armature 16- on suitable bearings-18 and 19 is a low tension armature 17 which is driven by means of gear-wheel 20 attached to one end of the armature shaft through the medium ofgearwheel 21 that is fastened to the ignition armature lfi. ()nthe end of the generator shaft ismounted a sleeve 23- which is free 24 carries governor weights 25 pivoted in any well known manner. Mounted in the end of the sleeve 23 is a ball 26 which runs against the friction bearing plate 27. This friction bearing plate is attached to a movable spring 28, which carries a contact 29. Mounted in any suitable manner within the auxilary plate 30 is a stationary member 31 carrying an adjustable contact 32. Members 2324-25 and 26 constitute a centrifugal governor which operates in accordance with the speed of rotation of the armature to close and open the contacts 29 and 32. The members 28 and 31 are both suitably insulated from the auxiliary plate 30. Also mounted within the auxiliary plate 30 is a somewhat resilient contact member 47 which carries the contact 48. The position of this member 47, and its contact 48 is determined by means of an adjustable stop 36 which is carried by member 31. The adjustable member 36 however, has an insulating piece 35, such fiber, interposed between it and the member 47. The members, 28, 31 and 47 have holes 37, 38 and'39 through which contact studs, 40, 41 and 42 are adapted to pass and to make electrical contact there with by means of suitable nuts screwed on to the said studs. Proper electrical connections are made to the inner end of said studs 40, 41 and 42 and by means of them, these connections are brought to the governing switch contact elements 28, 47 and 31. The said studs, 40, 41 and 42 are insulated from but fastened securely to the plate 43 by suitable bushings and insulators.

The end plate 43 carries an oil cup 44 for the purpose of oiling the bearing 19. The end plate 43 has a shoulder 45 adapted to fit within corresponding grooves, not shown, on

" pole pieces 2 and 3 in the diagrammatic arrangement shown in Fig. 7. After the plate 43 is mounted on the field frame of the generator by means of four screws through holes 55 being centered thereon by the annular shoulder 45, plate 34 is placed in position on plate 43, being guided by the dowel. pins 49 and the annular shoulder 50 which is fitted to the inner surface of the plate 43. The dowel pins 49 project on both sides of plate 34 and their outer ends serve to guide the auxiliary plate 30 by means of the holes 51. Screws 75 are then passed through the holes 54 into the plate 43, thereby holding the supplemental plate 34 and the auxiliary plate 30 in position on the plate 43. The upplemental plate carries oil cups 56 for the purpose of oiling bearing 12. An annular steel bearing ring 57 mounted within the boss 58 of the plate 34 provides a bearing for the cam holder 59. Also mounted within the boss is a plate 60 of good wearing material, such as bronze, upon which the ground brush, mounted on the backside of the circuit breaker 22, runs. 61 is a slot in the bottom portion of the boss within which the stop. pin 62 of the cam holder 59 moves. A cover 63 is adapted to fit on the auxiliary plate 30 to protect the circuit controlling springs, heretofore described, while a second cover 64 fits on the cam holder 59 to protect the circuit breaker mechanism 22.

Attached to the right hand end of the field pieces 2 and 3 by means of screws passing through the hole 65, is a main end bearing plate 66. Two additional screws are used to pass through the holes 84 and enter the polar extensions 52 and 4 to assist in holding the plate 66 securely in position on the field frame. The upper portion of this plate is adapted to carry a commutator housing or cap 67, the same being held to the main plate 66 by means of screws passing through the holes 38. In Fig. 4 the cap or housing 67 is shown withdrawn from the plate 66. The cap has an annular flange 68 which fits within the annular opening 69 of the plate 66. The cap 67 carries an oil cup 70 for the purpose of oiling the bearing 18, shown in Fig. 1. Mounted on but insulated from the cap 67 are brush holders 71.

These brush holders carry brushes which.

run on the commutator of the armature 17. The lower portion of the plate 66 has the boss 72, the opposite sides being machined flat to accommodate brush holders which are fastened to the boss by means of screws entering the holes 7 3. One portion of these brush holders enters the hole 74 and supports brushes that run on collector spool 15, which, in the case of a two cylinder machine carries a segment something less than 180 degrees. These brush holders and other de tails relating thereto, since they form nopart of this invention, are not shown. An oil cup 75 is carried on the upper portion of the boss 72 for the purpose of oiling the bearing 11. Mounted on but insulated from the plate 66 at the top thereof are three connecting studs, 76, 77 and 78. These studs are used for making the electrical connections with the interior of the machine as well as to the exterior circuits. The commutator housing or cap 67 has an opening 7 9 in the tcp for cover plate, not shown in Fig. 4 but adapted to be held thereto by means of screws entering the screw holes 80. cover plate is used for the purpose of inspecting the commutator. A cap 81 is adapt- 'edtogfit-around a rim 82 for the purpose of covering the commutator. housing and the circuit studs 76-, 7-7- and 78. The cap is held in place by screws which enter the holes 83 in the end of the commutator housing'67.

Surrounding-the field structure which carrice the two armatures, exciting and regulating coils, etc., I place a cover 85 which fits in the groo e86 ofwplated and around the rim 87 of plate 66;

It will be seen that I have arranged the end bearing plates of my generator in such a manner that they may be readily applied to the field structure-and that the plates for each end of the generator forming as it were units, which carry the necessary bearings and electrical connecting studs. The use of theconnecting studs, securely fastened to the end plates constitutes an. important feature of my invention as these fastening studs do away with a lot of flexible wiring which in the operation of the generator on a motorcycle-where vibration is excessive is apt to become displaced and the insulation worn, thereby causing trouble. By making the interior connections to the inner portion of the studs and extending these connections to the outer plates through insulating bushings, considerable time is saved in the assembly of the generator and a muchbe'tter job, both electrically and mechanically, is obtained.

It will also be seen that by the use of suitable covers for various parts that I have made my generator as nearly water and dust proof as it is possible to construct it.

It will be apparent to anyone skilled in the art that numerous changes and alterations can be made in certain details but these alterationsand'changes are believed to come within the scope of the appended claims.
