To all whom it may concern:

Be itknown that I, ALBERT C. HEMP L, a citizen or the United States of America,.and

resident of Bartlett, in the county of'Bell Sand State of'Texas have invented certain new and useful Improvements in Sparking Devices for Internal-CombuStion Motors, of which the following is a specification."

This invention relates to igniting means for internal combustion motor s, and has'referen'ce particularly to novel means whereby a plurality of sparks areproduced in a combustion chamber of a'mo'tor to insure proper firing of the charge therein.

A further object of this invention is to provide a sparking device if the character indicated, capable of being used in association with spark plugs such as are now commonly employed, with the exception that the spark plug must be devoid of a ground ing electrode.

A still further object of this invention is to provide a sparking device of the character indicated which may be installed in motors in a manner to prevent their being fouled by carbon, oil or the like, and whereby the contact between the electrode of the spark plug and the conductor of the sparking device may be so housed as to prevent the accumulation of carbon or oil which might have a tendency to interrupt the circuit between the sparking plu and the conductor leading to the sparking evice.

A. still further object of this invention is to produce a sparking device having an in sulating body adapted to be secured on the interior of a cylinder head in association with a sparking plug applied to the usual spark plug socket or hole.

lVith the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this application wherein like characters denote corresponding parts in the several views, and in which- Figure 1 illustrates a sectional view of a fragment of the cylinder head, showing a de- 4 vice embodying the invention applied thereto; V

Figure 2 illustrates a sectional view on the 55 line 2-2 of Fig. 1; and

' izr aregs mates carryin out the invention, I employ a spark plug 5 threaded acylinder head 6, the jspark plug having 'a singleelectrode "7 q'vhi'ch is adapted to conduct current to the sparkingdevice, as will presently appear.

Within the cylinderhe ad I prefer to. an-

chor' the 'sparking device which, .in the present eniljodimntjof the invention, comprises twofinsulating{disks 8 and, 9, secured. to-

geth r b rastenngs 103mm 1 1, which maybe 'intl'ie nature of bolts; the fastening 11 being employed also as a ground connection for the circuit.

The insulating disk 8 has an aperture 12 therein through which the electrode 7 projects, and the insulating disk?) has a recess 13 into which the said electrode projects.

A conductor 14 lies between the insulating disks and it terminates at the recess 13 in position to be engaged by the electrode 7. The conductor 14 extends through the in sulator 9 and projects over the surface of the insulator 9. Another conductor 15 is anchored in the insulator 9 with its end in proximity to the end of the conductor 14, in order that a spark gap will be formed between the said conductors. The conductor 15 is anchored in the insulator by reason of the fact that the said conductor 15 is looped as shown at 16, the said looped portion extending through the insulator, and the looped portion is bent to engage the inner surface of the said insulator so that the conductor cannot be displaced. There are a series of conductors 17, 18, 19, 20, 21 and 22, all of which are preferably anchored in the insulator in the manner described. Of course these insulators may vary in number to suit particular requirements, and they are in spaced relation to each other, in order to form spark gaps, so that when the current is delivered through the conductors, a spark is produced at each of the spark gaps. The conductor 22 is grounded through the con ductor 23 which is anchored on the securing member 11, thus establishing a sectional circuit with spark gaps between the spark plug and the ground. I

The conductor 14 where it engages the electrode of the spark plug is imbedded between the insulators, and hence these elements are protected from the accumulation of foreign substances which might have a v an underneath plan view- 0f the sa d device.
