SPARK-PLUG FOR INTERNAL-COMBUSTION ENGINES.
. Specification of Letters Patent.
Patented Nov. 1c, 1909.
Application filed. April 28, 1908. Serial No. 429,616.
To all whom it may concern:
Be it known that I, MAURICE EYQU-EM, of
191 Boulevard Iereire, 1n the city of Paris,
inanutacturer, have in- Republic of France,
for Internal-Combusvented a Spark-Plug tion Engines, of which the following is a being suddenly exposed to a very high temperature under the action of the still burning gases which pass through the same, is frequently broken and because the burned gases containing some carbon particles cannot produce a good cleaning.
The present invention relates to an improvement in a spark plug with a tubular electrode and a decompression cock for the purpose of producingthe cleaning of the plug not by means 01" the' burned gases but by fresh gases, that is to say by air containing particles of gasolene. This improvement is essentially characterized by the application to the plug of a device to out off the ignition when the decompression cock of thespark plug is opened; in this case, the spark plug is traversed by a gaseous mixture consisting of air saturated with gasolene; the cleaning is then simultaneously effected by the escape of carbureted air through the'spark plug, blowing and by the action of liquid fuel upon the fat matters.
The device adapted to cut off the ignition when the 'cockot' the spark plug is open is preferably constituted by a small metal rod mounted on the plug of the cock and in such manner that this rod will come in contact with the metal body of the spark plug when the cock is turned on, so as to form a shortci-rcuit-and thus cut off the ignition.
The accompanying drawing shows as an example a way of carrying out the present system of spark plug.
Figure 1 a perspective View spark plug in the normal working. Fig. 2 is a longitudinal section showing the spark plug in its cleaning position.
of the This system of spark plug comprises a i against the stationary abutment 2'. wire-clamp Z having a key-hole shaped openthat is to say by pelled without position it occupies in hollow rod a at the end of which the electrode b is mounted through the medium of a joint 0 having holes connecting the hollow rod on and the internal part of the spark plug.
.The hollow rod a is provided externally with a cock ending outwardly and on the plug of which is secured a contact rod or strip 7. This rod f, rel of the cock are of metal and in elastic connection with the hollow rod (4 upon which the electrode 7) is mounted.
The rod j is keyed upon the plug '6 so as to bear in the opening position of this cock, as shown in Fig. 2, against the metal barrel g of the spark plug and thus establish a short-circuit; the current-then no longer flows'through the electrode 1) and the ignition is thus cut off." i
The plug 6 of the cock carries an operating button it of insulating material and is 'continued'at its other end by a rod 6 act ing as a current conductor. pose,
For this purthis rod carries a stationary abutment i and a movable washer j which can slide and is pressed by a returning spring is The ing at (Fig. 1) is engaged between the stationary abutment z and the movable washer In order to facilitate the engagement and removal of the wire-clamp, the adjacent edges of the stationary abutment i and of the movable washer j are slightly rounded and the Wire clamp Z has a shoulder l, as shown in Fig. 2.
When the plug e of the cock is shut (Fig. 1) the rod f is removed from the inetal body 9 of the spark plug and the sparks can strike in the usual manner between the electrodes Z2 and a. \Vhen it is desired to clean the spark plug, the part e of the cock is turned so as to come to the position shown in Fig. 2; the rod f coming .in contact with the metal body 9 establishes a shortcireuit, the current then no longer flows through the electrode b and the ignition is thus cut off; furthermore, the hollow rod a being connected with the outer air, the carbureted air sucked into the cylinder is exburning and escapes outwardly in passing between the electrodes 1) and a, through the holes (1 joint 0 and the hollow rod a; in this course, this air saturated with particles of gasol ene or liquid fuel carries along the fat matters and the the plug e and the-bar carbon deposits which soil the electrodes and the inner Walls of the spark plug.
Claims 1. A spark plug for the ignition of internal combustion engines, comprising a tubular electrode, a cock mounted on the latter and opening to the exterior, a short circuiting rod arranged on the plug of the cock' and keyed so as to come in contact with the metal body of the spark plug when the cock is open, substantially as described.
2. A spark plug for the ignition of internal combustion engines comprising a hollow rod, a central electrode, a joint provided With holes on its periphery and securing the electrode to the hollow rod, a cock mounted upon the hollow rod and opening to the exterior, a short circuiting rod mounted on the plug of the cock, substantially as described.-
3. A spark plug for the ignition of internal combustion engines, comprising a tubu-' lar electrode, a cock mounted on the latter and opening to the exterior, a short circuiting rod mounted on the plug of the cock, an operating button of insulating material I.
mounted at the one end of the cock plug, at current conductor at the other end ot the 'cock plug, substantially as described.
4:. A spark plug for the ignition of internal combustion engines, comprising a tubular electrode, a cock mounted on the latter and opening to the exterior, a short circuiting rod mounted onthe plug of the cock, an operating knob or button of insulating material mounted at the one end of the cock plug, a current conductor rod constituting a continuation of the said lug, a contact abut me'nt carried by said rod :1 pressure washer movable on said rod and pressing against the contact abutment by a returning spring, and a Wire clamp provided with an opening, sul
stantially as described.
The foregoing specification of my spark ilu for internal combustion en 'iues si 'ned b b b by me this 17th day of April 1908.
