.ELECTRIO IGNITION DEVICE.

Application filed JulylO, 1908. Serial No. 442,931.

T 0 all whom it may concern:

Be it known that I, ARTHUR H. Mosrnn, a citizen of the United States, and resident of the borough of Manhattam in the city and State or New York, have invented a new and useful Improvement in. Electric Ignition Devices, of which the following is a specification.

lily invention consists in an improvement in electric ignition devices and has for its object to provide a multiple electric ignition device which is particularly well adapted for use in connection with double or multiple sys toms of ignition in connection with explosive structed and arranged that a cluster shell of: novel construction forms one electrode and the conducting wires of the several plugs term the other electrodes, a glass sight beingprovided, which glass sight is trained upon the sparking points of the electrodes so that the character of the sparks may be observed from the QYt-GllOl of the engine.

A practical embodiment of my invention is represented. in the accompanying drawings, in which- Figure 1 represents a top plan view o my multiple ignition device attached to the cylinder of an. explosive hydrocarbon engine, Fig. 2 is a section taken in the plane of the line A e of Fig. 1, looking in the direction of the arrows, Fig. 3 is an inverted plan view of the cluster shell, and liig. 4+. detail sectional view of a modified form.

The portion of the cylinder of an explosive hydrocarbon engine is denoted by 1. its explosive chamber by Z and its inlet valve by 5.

In. the "form shown in Figs. 1 to 3, inclusive, the cluster shell which forms part of the plural electric ignition device comprises an. inner member i, an outer member 5, and an intermediate member 6. The outer memher 5 has a screw threaded engagement with the hole 7, the intermediate member 6 has ascrew threaded engagement with the outer her 5 and the inner member l has a screw threaded engagement with the intermediate member 6. This inner member is provided with one or more open. 8 in its ""de walls beyond the end of the intermedi- 16 member 6 and a omit-rally arranged opening 9 in its end.

A packing ring tweenthe outer m.

10 may be interposed be amber and the wall of the Specification of Letters Patent.

Patent-ed May 2, 1911.

being so conengine cylinder be provided between the intermediate and outer members.

The intermediate member 6 is provided with a plurality of screw threaded holes 12. In the present instance, three-ct these holes are shown for receiving one or more spark plugs as the case may be. in the present instance, two of these holes are shown as receiving spark plugs and the other hole is shown as receiving a magnifying glass sight. This magnifying glass sight comprises a plug 18 having a screw threaded engagement with one 01'' the holes 152 and a magnifying glass 1i held in position by a ring '15, which magnifying glass is trained upon the hole 9 in the end of the inner member 4 for indicating to the observer the character of the sparks of the electric ignition device.

The conducting. wires 16 wl'iich term the central electrode of the two spark plugs oxtend diagonally inward so as to bring their points adjacent to the walls of the hole 9, the distance between the walls of the hole and the point of each of the conducting wires being less than the distance between sai points, so as to absolutely insure the formation of the sparks bctweei'i each of the points and the wells or the hole rather than between the points themselves. Each. of these conducting wires 16 is PYOVllli with an insulating block 17 heldin position between the screw plug 18 and cap 19.

"lhe conducting wire 1.6 is held in position between a. nut 20 in a recess .21 and thumb nut 22 engaging the outer end of the b 17. A. wasl'ier 23 is interposed etween nut 20 and the block i? for f ing In the form s tight joint at this point. v in F 1g. 4i, a smgle meinlier 24k 1s provide. it

stead of the inner and intermediate 11 hers, and the openings 8 and hole formed therein.

it is evident that a multiple electric igni tion deviee of this character may be made number of spark 'sh to limit myself and a packing ring 11 may i having its conducting Wire forn'i the other electrode, and a magnifying; glass sight mounted in said shell and trained upon the end of the said inner nnnnber.

2; A plural eleetrie ignition device comprising a cluster shell having a separable inner member provided with holes t lirrough its end and side walls and forming one electrode, spark plugs mounted in said cluster Shell and having their conducting wires form other electrodes, and a inagnifving glass sight mounted in said shell and tan: med upon the end of the said inner member.

3. An electric ignition device comprising a cluster shell having separable inner, outer and intermediate members, the said inner member being provided with holes through its end and sidewalls and forming one electrode, a spark plug mounted in the intermediate member and having its conducting wire fornrthe other electrode, and a magniying glass sight also mounted in the interl I, l

eemee mediate member and traii'led upon the end of the inner men'iber.

4. A plural electric ignition device comprising a cluster shell having separable inner, outer and interm diate members, the said inner n'iember being; provided with holes through its end and side walls and formingone electrode, spark plugs mounted in the intermediate men'tber and having their conducting wires form other eleetrmles, and a magnifying glass sight also mount-ed in the intermediate nieinl'axr and traintal upon the end of the innermember.

in teslin'ionv, that; 1 claim the foregoing as my invention. 1 ha v0 signed my name in presenee of two witnesses, this twenty fourth lay of June 1908.
