- 1906. Serial No. 344,703.

To all whom ctmnyconcem:

Be it known that I, TnEonoR HUBER'r, a citizen of the United States, and resident of New York city, borough of Brooklyn, New York, have invented certain new and useful Improvements in Electric Ignition Devices, of which the following is a specification.

This application is adivision of my. application filed April 4, 1906, Serialite. 309,736, for improvements in electric ignition devices, and my present invention has for its object to provide improvements whereby sparks may be produced at the same spark plugs either by means of a magneto or by means of a battery and .vibrator coil or coils, at will, by a simple manipulation, whereby the magneto may be cut out and the battery cut in circuit, or vice versa.

My invention comprises the novel arrangements and combinations of parts that will be more fully hereinafter set forthand then pointed out in the claims.

Reference is to be had tothe accompanying drawings forming part hereof, wherein Figure 1 is a'central sectional view of ya magneto having primary and secondary cir-, cuits adapted for use with my improve-l ments, Fig. 1 is a detail View hereinafter referred to, Fig.2 is a diagrammatic viewillustrating the combined magneto and bat? tery ignition circuits and controlling de-% vices, Fig. 3 is a detail view of the switch: shown in Fig. 2, and Fig. 4 is a detail sec? tional view illustrating a support for bind-- 24 attached to the magneto frame, the oppoing posts.

Similar numerals and letters of reference indicate corresponding parts in the several views.

The magneto 1 may be of any well known construction provided with a distributer for distributing the secondary current to ignit 111g devices or spark plugs 2. The armature 3 is mounted to rotate within usual fields,

(not shown) and shaft 4: of the armature ll'l.

rigidly attached thereto and mounted I suitable bearings cai'rledbythe magneto frame. The primary winding 5 of tie armor ture is shown connected with a metal plate .6

rigidly carried by the armature :but insu-' afrom the frame of the magneto.

lated therefrom, as by insulation 7, and engaging a brush 8 carried by but insulated At 9 is a contact in the primary circuit supported by and insulated from the frame of the mag- 'neto, and at 10 is a movable contact shown carried by a pivoted arm 10 supported by the frame of the magneto, which arm may be grounded through the frame with which one terminal of the primary winding may also be grounded. The contact 10-is operated by a cam 11 carried by the magneto shaft 4*, saidcam being shown provided with two projecting portions to engage a roller 12 of arm 10., a coil spring 10 serving to pull the arm toward the cam, all whereby when the primary magneto circuit is closed and opened the discharge in the secvondary armature winding 13 will be produced in well known manner in high tension magnetos. To control the magneto primary circuit at will I providea switch indicated at, 14.- in a branch line 15 as more fully hereinafter explained.

The secondary magneto winding 13 is shown connected by a screw 16, insulated from shaft 4, with a spring pressed contact 17 in circuit with a binding post 18 shown carried by an insulating cap 19 screwed upon the magneto frame, the post '18 being shown connected (Fig. 1) by wire 2Q with "a post 21 in circuit with a distrib'uter con-- tact. 22, as by means of a spring pressed contact 23 shown carried by an 1nsulat1ng cap site terminal of the secondary winding being grounded through the magneto frame, as indicated in Fig. 2. As shown in Fig. 2 and as hereinafter explained I provide a switch, as at 25, in the secondary magneto circuit. Withthe arrangements above described and the primary and secondary magneto circuits closed, [current will be generated during the rotation of armature 3 as in well known high-tension magnetos, the discharges in the secondary circuit being produced during the make and break of the primary circuit as the cont'acts'9,1'0. I

Ijmvtmsbcwn means to advance and retard either direction around shaft 4 said arm and the ignition or sparking in internal combustion engines by advancing and retarding the armature 3 with respect to the armature driver or pistons of the engine, and also for advancing and retarding the movable contact 22 of the distributer, as follows: Upon the magneto shaft '4 is loosely mounted a sleeve 26 provided with one or more projections or pins 26*, 26" that enter spiral grooves 4 in shaft 4, and upon sleeve 26 is mdunted an arm 27 Whose hub portion 27 is so connected with sleet-e 2621s to rotate with respect thereto and yet not have lateral motion independent of said sleeve. I have .-v shriWn ball bearings interposed between'hub 2'7 and sleeve, 6, the latter being shown provided with a ball race 26 receiving the balls 28 that are within a ring or the like 29 carried by hub 27 and shown held in place by a retainer 30.

Hub 27 is shown provided with pins 31 that extend into slots 32 in blocks 33 secured on the magneto frame (see Fig. 1") which slots are disposed at an angle to the plane of arm 27, said slots extending in opposite directions whereby as arm 27 is rocked in thereby sleeve 26 will be caused to move to the right or left the desired distance along shaft 4 by reason of the ball bearings interposed between said sleeve and hub 27. This sliding motion of sleeve 26 on shaft 4 will,

by reason of the projections 26 of sleeve 26 entering grooves 4 in shaft 4, cause said shaft to be rotated more or less and thus will adjust the armature correspondingly with respect to its fields and thereby with respect to'the point of connection between shaft 4 and its driving part, such as an engine shaft, cam 11 being similarly adjusted with respect to contact 10. Connection is to be made between the driving part or an engine shaft and sleeve 26 so that shaft 4 of the armature will be free for adjustment with respect to the engine shaft and yet be rotated thereby, and to this end I have shown a sleeve or driving part 35 mounted freely upon shaft 4 and provided with internal grooves 35 that receive the arms or projecting portions 26 of sleeve 26, in the nature of a tongue and groove connection, whereby sleeve 26 may'slide along shaft 4 freely with respect to sleeve anclmaintain rotary connection therewith.

- The sleeve 35 is to be rigidly connected with a driver, as with a shaft of a gas engine, whereby the rotation of said shaft will be communicated to armature 3. With arm 27 inposition to causeretarded breaks in the secondary circuit of the magneto the explosions in the engine cylinder, indicated at A, Fig. 2, will be. late, and toadvance the spark in the cylinder the arm 27 will be rotated a suitable distanceto cause it tomove laterally thereby moving sleeve 26 to the right in Fig. 1) to rotate shaft 4 forwardly in ependently of sleeve 35, thereby also advancing cam 11 with respect to contact 10, whereby the break in the primary magneto circuit will be caused to occur earlier than before, and so on according to the position of arm 27. To retard the spark,

arm 27 is moved reversely thereby correspondingly rotating shaft 4 and armature 3 reversely with respect to sleeve 35, thus retarding the breaking of .the primary magneto circuit with respect to the engine pistons.

The distribution of the secondary current for a plurality of spark plugs 2 of the engine cylinders is produced by the contact 22 whose shaft 40 is geared to the shaft of the armature, as in the ratio of two to one for a four cylinder engine, by means of gears 41 and 42 carried by said shafts respectively, as shownin Fig. 1, and thereby it will be understood that as shaft 4 and its armature 3 are advanced or retarded with "respect to the driving part or engineshaft the distributer contact 22, through said gearing,

-will be correspondingly advanced or 'retarded to cause the distribution of the secondary current for the several cylinders of the engine to accord in time and position with the breaking of the primary circuit of the magneto, the contact 22 controlling contacts 22, 22 22 and 22, to be connected with wires a with the spark plugs 2.

The above described magneto, and the means for advancing and retarding its armature with respect to its driver or an engine shaft illustrate a high tension generator adapted for use in connection with my improvements, and I' have shown in Fig. 2 means whereby a battery circuit and vibrator coil or coils may be used in connection with said high tension magneto and its circuits, and wherein when the battery circuits are being used the magneto circuits may be cut out, and vice versa. To this end I have shown the wire 15 of the primary magneto circuit connected with a binding post 6 and the wire 15 of said circuit connected with a binding posts, wires 15", 15 connecting said posts 6 and-c, respectively, with contacts d and e. The circuit through contacts (2 and e is adapted to .be opened and closed by the contact or switch 14 that is shown secured ,to an insulating block 45 controlled by a handle orvbutton 45*, suitably journaled, whereby when circuit is closed at d, e the current will fiow from brush 8 through 15, 15 (Z, 14, e,

and 15*, the contacts 9 and 10, and thence through the -primary coil of the magneto back to brush 8. The secondary circuit of the magneto is also to be opened and closed with the opening and closing of the primary circuitthereof, and to this end the circuit, I

tween contacts (5 and e, as shown in dotted lines in Fig. 2. Switch is shown secured to insulatlng piece 45 so as to be operated colncidently with switch it. Thus, when switch 25 closes circuit between contacts f and g the secondary circuit of the magneto will be; from the secondary winding 13 through. post 18, wire 20, contact f. sw1tcli 25, contact, g, wire 20*. contact 22. and

through contacts 22, 22". 22 or 22 and wire a to ground at .the engine. and. thence through the frame of the magneto back to the secondary winding. as indicated by wire w in Fig. 2.

The battery, with the primary and secondary .of the vibrator coil and their circuits are "indicated in Fig. 2 as follows From battery 46 the wire it leads to the i primary coil 47, and thence by wire 2', contactj, and vlbrator spring 7a through wire Z,

ton contact m, and froin'an associate contact a, th'roughwir'e 0, post p, and wire Q, to a spring or contact 48 adapted to make. and break circuit with moi'able member 10*, which member leads thence back-to the battery as by ground'through' the mechanism,

indicated in Fig. 2 by wires 1 and s to ground. The contacts I), c, and p are shown .carried by an insulating piece 50, such as rubber, that may be held upon the magneto frame by screws 51, (see'Fig. 4;). Switch 14 is adapted to open and close the circuit through contacts m and n. and when in such position, as shown in Fig. 2, the rotation of cam 11 will causelthe primary battery cir cuit to be made and broken at contacts 10 and 48. Thus it will be seerfthat the time of the make and break between contacts 10" and 48,'ca'i1sed by the lifting of contact 10 by cam 11, will be slightly retarded with respect to; themake and break between con- 'tacts 9 and 10 of the primary magneto circuit,so that, for instance, whenthe engine is being started by means of the battery circuit the spark will be slightly retarded with respect to thetime of theretarded spark produced by the magneto, because'the latter occurs at th'e'break'between contacts 9 and 10 and the battery circuitbreak does not occur until after the camlias left arm 10and spring 1O has pulled the latter from contact 4'8, thereby making it more safe'to the operator, as respects a back kick from the engine, to-start the engine with the battery circuit. The secondary winding 49 of the vibrator coil is grounded atone terminal,

as through the mechanism, or through wire h in Fig. 2, and the wire .25, leads from the other terminal to the contact u to be engaged by switch 25 to place said winding in circuit with contact 22 through contact 9 and wire 20 when switch 25 is in the position shown in Fig. 2. Thus, when the battery primary circuit is closed by switch 14 at contacts m, n, the battery secondary circuit will. befrom ground or the mechanism through winding 49, wire 23, contacts at and 9,

contacts 22 22 22 or 22 and wire a to the engine and back to ground. I

From the foregoing it will be understood that by simply turning button 46 for conswitch 25, wire 20 contact 22, and through tacts cl, e, and f, g the magneto primary and. i secondary circuits may be closed for operat-ing the igniting devices while the battery primary andsecondary circuits will be broken, and that by placing the switch in the position shown in full lines in Fig. 2 the magneto primary and secondary circuits will be broken while the battery primary and secondary circuits'will be closed for the igniting devices.

As the switch 14:, as shown in Fig. 2, is

adapted to control both the primary'of the magneto circuit and the primary .ofthe battery circuit I have shown said: switch make firm contact with the contacts cl and e of the magneto secondary circuit to prevent IIIJIH'Y from sparks thereat.
