-To'a'll whom it may concern.-
Beit known that I,4 RrrcrneS. Garner, a sub'jectof the"King-of Great Britain, residin at'Victox-ia, 1n .the Province of British olurnbia and Dominion o'f-l Canada, have invented 'certain new and uscful Improvements in Sparking Devices for In- -ternal-Co'mbustion Engincs, of which the following is a specification.
This invention relates to internal coinbustion engines, and particularly to the 1gnition systems therefor.
The primary object of the invention is to provide an iii-:proved spark plug for use in connection with the Iexploslve cylinder of an internal combustion engine, and which is capable of being examined, cleaned, or repaired withougremoving the plug from A further object of the invention is to provide a plug of this characte;- which incl des a plurality of separate and distinct sp rk points, and whlch is capable of being readily actuated so as to dispose any of the sparking gaps in communication with the explosive cylil'ider. still further object of the invention is to provide in a spark plug of this character, lmprocd means for establishing an clert rical connection between the source of cnergy und that pair of points onl 'which is A in conmunication with the exp osive cylindcr.
Still fher objects reside in providiiiga mechanism of this character which is capable of bein constructed so as to beapplicable to cy inders of engines now in use; which requires no change in thevwiring of the ignition system,'whichris capable of bcing manufactured at comparatively lowv cost; which may be quickly and easily attached to or detached from the engine cylinder when required; which is simple 'of construction and'opcration; and which will prove thoroughly efficient in the attainment of the ends for which it is designed.
Eig'ure 1 is a top plan view of a portion of van internal combustion engine, and illustrating the application of a sparkingmechanism yonstructcd in accordance with the invention;` A
Fig. 2 is a sectional view taken Substantially on the line 2--2 of Fig. I;
Fig. 3 is a view of one end of the sparking device; and
Fig. 4 is a similar view of the opposite end of the sparking device with the retaining cap removed.
Theinvention in its preferred embodinlcnt includes a barrel, body portion or casing indicated at 5, and which is provided with a laterally projecting tubular or stem portion (3. The tubular portion Vis threaded Lpon its exterior surface so as to be capable of being screwed within the spark plug opening of the combustion engine cylinder. The easing 5 is novided at a point preferably diametrically opposite to the point of communication of the stem G therewith with an upwardly disposed flange 7, and a lid 8 is hinged to the flange and is'capablc of closing the opening defined thereby.
This casing is constructed preferably ol' metal, but it is obvious that other nnlterials may be used if desired.
llotatably mounted within tbc barrel or casing 5 is a spark plug, in the forni of a core 9. This core is constructed of suitable non-comlueting material, and is of a Size to lit snugly within the barrel. This core is provided wilh notched or cut away porlions Il), the said portions being so located upon the core as to be capable of opening info the hollow stem portion (3 and the opening defined by the llange 7, and within each of the notched portions is located a pair pl' sparking points 11. 'lhe sparking points in the present instance are formed oy extending conductors l2 longitudinally of the core and spaced inwardly I'rom the outer surface of l'hc latter. Une rnd ol each of the conductors extends outwardly as at 13, and engages with the inner wall of the mctallic casing fr. The opposite ends of the conductors project beyond the extremity of the cole and provide ront-act points 14.
'Ilnl end of the coro opposite to that at which the contacts 14 are located is provided with a turn key l5, by ini-ans of which the plug may he readily rotated. Adjacent the last named end of the mrc and projecting from one side thereof is a pin or projection 16, which is adepti-dto engage stops 17 formed on the end ofthe easing or barrel 5. The projection and stopslG-l are so arranged that when engagml. one of thel notched portions 10 of the core will be in communication with the hollow stem (i, while the other notched porlion will be disposed directly beneath thelid or cover 8 of the casing.' When the plug is rotated S0 ap at that the. projection 1G is engaged with the oppositely arranged stop, the notched portions 10 will be in reverse iosition.
The means by which t e conductors 13 are operatively connected with the ignition system includes a standard 18 secured to and insulated from the cylinder of the engine adjacent the contacts 14 of the rotatable plug. This standard is yoked at its upper portion so as to )roride a pair of spaced arms, within whic the protrudin contacts 14 upon the core are confined. ese contacts however can only engage the standard 1S one at mtime, and the arrangement is such that one or the other of the contacts is engaged only when the plug has been rotated to its extreme limit in one direction or the other. The standard 18 constitutes a terminal of the ifnition circuit, and it is apparent from theorcgoing that only those sparking` points which are in communication with the hollow stein 6 are energized.
Any approved means can be employed for maintaining the core in proper position within Ithe casing 5, but inthe present `instance. a detachable ferrule 20 is threaded upon one end of the barrel and encloses the adjacent end of the core, while a nut .21 is th readedl y engagedwith a reduced portion at the opposite end of the core. The ferrule and nut prevent movement of the core longitudinally of the casing, but permit of the. core being freely rotated.
When the standard 178 is properly connected with a source of energy and the core 9. has been rotated to its limit in one direction, it is apparent that one of the contacts 17 will be engaged 'with the terminal 18 so that the electrical circuit is completed; it being understood of course` that the circuit will be grounded through the engine cylinder. by reason of the constant engagement of the end 13 of the conductor with the easin or barrel 5. When in the position indicate in Fig. 2,' the s ark gap at'the lower side of the'core wil be in direct communication with the interior of the cylinder, while the the upper part of the core will he is sed beneath the lid or cover 8. Should it e desired to clean or repair the spark points 11, the lid may be raised, whereby access ma be readily had to the said oint.
From tile foregoing it is apparent trat I have'provided an extiemely simple and yet thoroughly eicient means for the attainment of the ends set forth. The plug may be readily turned when it is ouiu that the sparking points at one side thereof are. inoperative. The plugs may he readily dctached from thc casing when desired. so :is to be supplemented by new' plugs. I have described the plug or core in the pieseut instance as being provided with a pan' of conductors 12, but it will be understood that any desired number of such conductors may y gine cylinder; of a core rotatablfy be provided upon the core if found expedient.
While the present disclosure is that of what I believe to be the preferred embodiment of the invention, it is to be understood that the invention is not limited thereto, but that various changes may be made in the construction, arrangement, and proportion of parts, without de )artin r from the spirit of the invention, as efineriiin the appended claims.
It will be seen thafthe device is especially ada ted for use with motors of aeroplanes as t e plug may be turned in Hight should engine trouble or fouling occur, and this will obriatethe necessity of descending and alightinrr to make re iairs, as hy changing the ordihary type o plugs. The notches or out away portions 10 also produce cups permitting the electrodes to be primed by opening the cover or lid 8, so that when the lug is thrned a half revolution the. Spar 'ng system will be' operative and operation of the motor may be continued. The, uppermost electrodes may also be conve.3 ientlyl cleaned of carbon deposit, corrosion or ot er foreign matt/er,l by opening the cap 8, so that it will `always be ready for use, inasmuch as any or all of the plugs may be changed to bringl into operative position a `clean set of electrodes, without the necessity of stopping the engine.
