13 Claims, 9 Drawing Figures IGNITION INDICATOR BACKGROUND OF THE INVENTION This invention is in a field of indicating devices to determine by visual indication, the operability of an ignition system.
No prior art wherein the visual indication of an ignition system by a device which is integral with such system, is known.

EXEMPLARY EMBODIMENT Referring to FIGS. l-9, an electrical ignition system, comprising a distributor 30 driven by engine shaft 10, and connecting wires 18, 20, 22 and 24 to a plurality of igniters 19, 21, 23 and 25 which are grounded to the engine as at 29, has provided or adapted thereto means 40, 50, 60 or 81 containing gas integral with said system for indicating operation of said system due to periodic ionization of the gas illuminating said means. The distributor normally comprises lower member 31 through which shaft 10 extends, and distributor cap 32 which has parts 34 and metallic inserts 16 molded or attached inside ports 34 that extend into the inside portion of distributor cap 31.
In referring to FIG. 9 which particularly shows operation of the inventive device of FIGS. 4 0r 6 adapted or used in different ways, FIG. 9 shows that igniter 19 is connected directly to the recess 16 in member 14 with no inventive device used in this part of the circuit. But igniter 21 that is connected by means of wire 20 to its counterpart member 14 at recess 16 therein has wire 20 extending through the axis 52 of the device such as illustrated by FIGS. 4 and 5, and therefore shows such device at 26. Igniter 23 is connected by means of wire 22 to the inventive device as illustrated by FIGS. 6 and 7 where one end of wire 22 is inserted in port of one end of metallic member 64 whereas the other end of member 64 is inserted in depression 16 of one of the terminals 14 of the distributor cap, and hence use of such inventive device is illustrated at 27. Igniter 25 has its metallic cap inserted and connected into one of the ports 65 of the device shown in FIGS. 6 and 7, the other port 65 of this device being used to adapt and insert therein one end of wire 24, the other end of wire 24 being inserted into depression 16 of one of the metallic members 14 embedded in the distributor cap. Therefore, it can be seen that upon supplying energy to any of the igniters when one of the inventive devices is used in the ignition circuit, such as ignition wires extending therethrough, one of the devices attached to the igniter directly or adapted to a port of the distributor cap, the electrical energy by virtue of the ignition action creates an electromagnetic field that ignites the gas internal such device in accordance with the pulsing action of the ignition pulse energizing the igniter. Hence, during satisfactory operative conditions therein, indication that a particular igniter is firing properly or that such portion of the ignition system is operating satisfactorily is provided by visual observation of ignition of the gas due to periodic pulsing and gas ignition in such inventive device, by the pulsing of the electromagnetic energy induced therein by normal ignition action. 7
Therefore, in accordance with this invention it would be desirable to use a gas such as neon, argon, xenon, krypton or mixtures thereof due to low ignition energies required.
One manner of constructing the inventive device is to provide an adaptor as at 40 which may be constructed of glass or a transparent plastic. Adaptor 40 comprises a web portion 41 that joins hollow cylindrical members 42. Each member 42 can be provided with sealable ports 42a and 42b for exhausting the residual air therein and for pumping in one or more of the gases therethrough, respectively. After each operation of exhausting air or pumping gas the respective port may be sealed by fusing the entry to ports 42a and 42b. Web 41 has an aperture 45 at its center to admit port 33 of the distributor cap, whereas each of cylindrical members 42 have apertures 44 at their respective axes for admitting ports 34 of the distributor cap. In each members 42 a cavity 43 is provided in which the pumped-in gas is permanently retained.
With respect to each cylindrical member as at 50 having outer wall 51, such member may be most conveniently used in connection with an ignition wire extending through aperture 52 for providing the requisite field to energize the gas in cavity 53. As in the former instance, air is evacuated through port 51a and this port is sealed, and gas pumped-in through port 51b and this port is then sealed.
With respect to each of cylindrical member as at 60, this cylindrical member having outer wall 61, aperture 62 at its axis, and air evacuation port 61a and gas injection port 61b, is identical to member 50 with outer wall 51, aperture 52 and ports 51a and 51b. The only addition to member 60 is metallic rod 64 extending through aperture 62. Rod 64 has depressions or ports 65 at either end thereof for adaptation to the cap of an igniter at one end, and for insertion of an ignition wire in the other end in port 65, as the case may be, in accordance with the manner of use described in connection with the various adaptions shown in FIG. 9.
Another manner of utilizing the inventive device, particularly as shown in FIGS. 4 and 5, is illustrated by FIG. 8. Therein the device denoted at 81 is shown molded to or adapted to port 34 member of the distributor cap 32 at interface 85. Of course member 81 may be an integral portion of the distributor cap, so that if the distributor cap is made of pyrex glass or of polystyrene for instance, member 81 may be molded at the same time and share a common wall such as the wall of port 34 with that of member 81. In any event a chamber or hollow portion as at 83 is provided in member 81. Naturally, as many members 81 as there are igniters or ports 34 are provided for each such integrated cap. In FIG. 8, such integrated cap is shown, in-part, partially cut away to show how member 14 with depression 16 therein is molded within each port 34.
With respect to device 40, this device can be integrated or attached to distributor cap 32 by providing an adhesive layer between the upper surface of the distributor cap and the under surface of device 40, or these two surfaces may be molded to each other by use of appropriate molding process.
Therefore, means 40 may comprise a plurality of members 42 joined by a web 41 where each of said members contain said gas in hollow portions 43. Means 40 may be integral with a surface of distributor cap 32, and may comprise transparent envelopes 42 as well as web 41. The hollow transparent envelopes containing gas may also comprise means 50, 60 or 81. Hollow cylinders 50 or 60 may have metallic rod 64 extending therethrough for interconnecting the rod between one of the wires 22 and the distributor as at 27 or for interconnecting the rod between one of the wires 24 and one of the igniters, as at 28. Means 81 may be integral with distributor cap 32 by means 81 being molded or otherwise attached at interface 85 to distributor cap port 34. Means 81 may be of glass or transparent plastic material, and have provided sealable ports such as 51a and 51b (not shown) for evacuation of air, injection of the gas therein and sealing by melting or fusing the sealable ports to retain the gas therein. Means 81 may comprise a plurality of such transparent members, each member containing said gas and each member being equally spaced from each other about the periphery of the distributor cap.
