To all whom i! may concern:

Be it known that I, WILLIAM B. HAYDEN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Electrical Sparking Devices for Explosive-Engines, of which the following is a specification. I

This invention relates to electrical sparking devices for explosive engines, and aims to provide a device of such class in a manner as hereinafter set forth, withelectricallyoperated means for moving an electrode to and from contact with another electrode, both of which are in a spark circuit, thereby creating the ignition spark. The circuit for operating the said means, which is termed the main circuit, communicates with a single source of electrical energy while the spark circuit communicates with two sources of supply, one of which is the source for the main circuit. The main circuit is opened and closed during the operation of the engine by the timing device or the circuit-making and breaking means carried by the engine, while the spark circuit is opened and closed owing to the actuation by the electri calYy-operated means, of a movable electrode which intermittently engages with a fixed electrode, thereby creating the ignition sparks. v

The invention further aims to provide the device with me'ans to form what may be termed a starting circuit for initially throwing into operation said electrically-operated means, forming an ignition spark, thereby igniting the explosive mixture in the combustion chamber of the engine, causing the explosion of such mixture and the operation of the engine; consequently causing the intermittent operation of the timing device or ci rcuit-making and breaking means carriedby the engine, thereby creating the ignition sparks. The said starting circuit when closed so as to create the spaik, owing to the-actuation by.the electrically-operated means of the movableelectrode', overcomes the necessity of cranking motor boat, the closing of the starting circuitcuables the operator to readily start the engine without any in-- convenience, as is generally the case at present.

The invention further comprises in its construction a plug set up in such manner that'the movable parts When used for a'motor vehicle 01" thereof can be kept in a state of lubrication owing to the fact that the bearings for the said movable parts are arranged away from the heat of combustion in the cylinder of the engine.

The invention further aims to provide an electrical sparking device for explosive engines which shall be extremely simple in its construction, readily positioned with respect to the cylinder of the engine, eflicient in its use and operation, strong, durable, obtaining an in- I tensified ignition spark, easily set up in operative position, requiring no complicated wiring, compact, enabling an operator to obtain what may be termed the initial spark, in a convenient manner and comparatively inexpensive to manufacture.

With the foregoing and'other objects in view, the invention consists of the novel construction, combination and arrangement of parts hereinafter more specifically described and illustrated in the accompanying drawings, which form a part or" this specification, and wherein is shown the preferred embodiment of the invention; but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In describing the inyention in detail, reference ishad to the accompanying drawings, wherein like reference characters denote corresponding'parts throughout the several views, and in which:

Figure 1 is a side elevation of a sparking device in accordance with this invention, with the circuit connections removed; Fig. 2 is a top plan; Fig. 3 is a section on j line 3-3, Fig. 2; Fig. 4 is a section on line 4- 4, Fig. 2; Fig. 5 is a perspective vie/w of a movable electrode and shifting means therefor, theparts being disassembled, and Fig. 6 is'a diagrammaticai view of a sparking device in accordance with this invention, showing the circuit connections.

'An electrical sparking device for explosive engines in accordance with this invention, comprises a sectional hollow plug open at one end and closed at its ether end, the inner or 0 en section bein indicated is r P g I the reference character 1, ano the outer or closed section indicated by the reference character 2. The sec in 1 is open from end to end, 15 exteriorly screw-- threaded, as at 3, and at one end is providil with a protuberance 4 which is slitted to receive a'contact point 5, preferably constructed of platinum. The protuberance 4 is arranged at the lower portionof the section .1, and the said protuberance 4i withthe contact point 5 forms a fixed electrode. The section 1 is adapted to be screwed into the enginercyglinder 8 so thafthefixed electrode will project into the combustion chamber of tlie engine and cooperate with a vibratory electrode to be hereinafter referred to, said vibratory electrode also projecting into the combustion chamber oi the engine. Holdfzlst means, as at 7, is provided upon the section 1 which abuts against the cylinder 6 so as to prevent the looseningbf the section 1. The outer end of the sec tion 1 is formed with a plurality of apertured ears or lugs 8, for a purpose to be hereinafter referred to. The section 2 of the plug has its outer end closed and its inner end open, and the said section 2 is hollow and provided with apertured lugs or protuberances 9 of the same contour as the aportured ears or lugs 8. The section 2 is adapted to be secured to the section 1 through the medium of the hold fast devices 10 extending through the apertured ears 8 and 9, and the two sections 1, 2 are insulated. from one another through the medium of the insulating material 11 which is interposed between the inner ends of the said sections and clamped between the same by the holdiast devices 10. Any suitable form of insulating material may be employed. Although the sections 1, 2 are provided with apertured ears or lugs which receive holdiast devices forconne'cting said sections with one another, yet any other suitablemeans for this purpose can be employed, and although the sections 1 and 2 are shown substantially square in contour, yet the same may be of any suitable shape. The section 2 is provided atone side with an opening closed by a removable plug 12. By such an arrangement, access can be had to the interior of the section 2 for cleaning it, or for other purposes.

The reference character 13 denotes an electro magnetic device which is suspended in close prcximity to the closed end of the section of theplug, and the said cult-wire 23 and leading from the post 19 to the elec-' device 13 is suspended through the medium of a casing 14 which is suitably connected to the device 13; and

- the casing 14 is formed with an arm 15 secured upon the section 1 by the holdfast devices 16 and provided with a vertically-extending portion 17, to which binding posts l8, 19 are connected but insulated therefrom. From the post 18leads the wire 21 to the magnet, and from the magnet to the post 19 lead the wire 20. Leading from the electrical source 22 to thep'ost 18, is a cirtrical'source 22 is a circuit wire 24. interposed in the circuit wire 23 is the timing or circuit-making and breaking device 25 which is carried by the engine. ln-

terposed in the circuit Wire 23 is a suitable switch 26. The armature of the magnetic device is indicated. by the reference character 27, and is provided with a depending arm 28 carrying an adjustable lilting screw 29,

l the function of which will be hereinafter referred to;

downward movement of the armature.

I irom a point in the section 2 of the plug through the section 1 of the plug, is arranged within the said section so it will not contact with either of them, and has that end which is positioned in the section 2 suitably connected,

as at 35-, to the inner end of a rock-shaft 36 which is mounted in one wall'ol the section 2 and in the bearing arm 37 which projects laterally from one side of thescc' tion 2. The inner end of the shaft 36 is provided with a bifurcated head 38 having a screw-threaded recess "38, and the said bifurcated head 38 is adapted to receive one end of the arm 33, the latter being provided with an opening 38 through which extends a holdiast means 38, the said holdfastmeans 38 engaging in the screw-threaded recess 38", thereby securing arm 33 to the head 38 of the shaft 36. The head 38 bears against the inner wall of the section 2 and acts as a means to prevent leakage through the opening in the section 2 in which is mounted the shaft 36. Fixed to the rockshaft 36, through the medium of a pin 38 is a sleeve 40 recessed, as at 40, to form a pocket to receive a spring 40 which also engages in a pocket formed in the outer face of the side wall of the section 2 through which the shaft 36 extends. The spring 40 acts as a means to re tain the head 38 against the wall ofthe section 2.' The sleeve 40 is provided with a longitudinally-extending actuating arm 41 which isof such length as to extend over the adjustable lifting screw 29 so that when the armature 27 is elevated, the screw 29 will engage the arm 41 and rock the shaft 36, thereby shifting the movable electrode against the fixed electrode. The electrodes are normally retained separated through the medium of an adjustable compression spring 42 mount? ed upon the arm 41 and engaged by an adjustable member 43 carried by the arm 15, the latter being provided with an offset to receive the said member 43. The tension of the spring 42 is regulated through the medium of the adjustable member 43. i

The main circuit is formed by the circuit wire 23 ironrthe electrical source to binding post 18, branch wire 21 to magnet 13, through the magnet, thence to binding post 19 and circuit wire 24 to source 22. The timing or circuitmaking and breaking device 25 and switch 26, as before stated, are interposed in the circuit wire 23.

With the electrical source 22 is coupled, as at 22*, an electrical source' i. The two sources of supply 22 and 44 are in the sparking circuit and the said circuit is formed by the coupling 22, and circuit wire 45 leading to a non-vibrating coil 46. From the coil 46 leads a branch wire 47 to the engine bed 48, through the engine bed 48 to fixed electrode, through vibratory electrode, section 2, binding post 48, circuit wire 49, part of wire 24, thence to coupling 22. The interposition of the non-vibrating coil 16 acts as a means to intensify the spark, as will be evident. The non-vibrating coil may be of any suitable construction.

From the arrangement of the circuits it will be evident that the main circuit is somewhat weaker than the sparking circuit as it embodies but a single electrical source, consequently as the sparking circuit em bodies the two-fold source of electrical energy, the

scones making and areal words, the spark will not be suede until the main circuit is broken. The plug when set up lias'only a. portion oi the screw-threaded section l. extending in the cylinder, the section 2 being in 2. position at a point removed iron: the cylinder and by such arrangement,

it is evident that the movable parts or the plug and engine so as to bring the elements of the timing or.

circuit rnaking and breaking device into contact to form initial spark, starting circuit is provided.

which is independent of the main circuit, and which is adapted to energize the magnet so as to form the initial spark. This starting circuit comprises a switch in the form oi an ordinary push-butt0n, the movable member of which is indicated by the reference character 50, and the fixed member by the reference char actor 51. The push-button is interposed in the circult wire connection 52, leading from an electrical source 53 to the circuit wire 23, and-leading from the vice can be understood from the foregoing descrip tion, taken in connection with the accompanying drawings, but it will be s te ted that whe'nthe electro magnetic device is energized, the armature 27 will be attracted; consequently moving the contact points 5 and 34 together. When the magnet is-denergiZed,

the action of the spring 42 will causethe contacts 5 and 34- to separate, thereby creating a spark. The

energizing end deenergizing oi'the magnet 13 will be had while the engine is running, and owing. to the action of the movable electrode with respect to the fixed electrode, it will. be evident that the sparking circuit will be intermittently closed and opened;'

consequently intermittently creating an ignition spark which will be intensified owing to the interposition of the soft core coil or non-vibrutingcoil, or what may be termed a primary current coil. The initial energizing oi the magnet so as to form the initial spark is bad, as before stated, owingto the operation in one direction of the push-button, thereby ,closing the starting circuit which will remain in such condition untilpressure is removed from the push button, this formins' the initial seer- I .J r
