Application filed April 26,
T all whom it may concern.
Be it'known that I, Ancusrn PACHE, a subject of Switzerland,residing in the city of New York, borough Manhattan, county and State of New York, have invented a certain new and useful .SparkPlug-COntrolling Device for. Internal Combustion Engines, of which the following is a specification.
The invention is designed for use on aeroplanes, automobiles, boats and all gasolene and gas motors. The apparatus is so placed as to be controlled by the driver from his seat and can be used in conjunction with any internal combustion engine, to allow of the cleaningof the spark plug at the will of the chauffeur or driver.
The object of the invention is to provide means operable irom the drivers seat, to allow of the selective operation of any particular spark plug 01"- the internal combustion engine, by which the vehicle is propelled, to be individually operated by the driver for the purpose of allowing the compression or burning gases from the cylinder tobe exhausted throughthe plug,to free the plug from carbon deposits, dirt or oil. A further object of the invention is to pro vide a simple construction for carrying out the first enumerated object and to so organize the parts that the electrode of any rmrticular plug, or the entire plug itself, may be readily removed without requiring dismantling of any of the operating parts of the device.
The drawings illustrate the preferred, practical embodiment of the invention, but it will be understood it is not confined to the speciiic structure shown, the same being typical, but not exclusive, of the forms in which the invention may be embodied.
In the drawings, Figure 1 is a side elevation of the invention as applied to the ordinar; type of eight cylinder engine;
Fig. 2 is a section on line 2-2 of Fig. 1; Fig. 3 is a top plan view;' Fig. l is a fragmentary perspective view;
Fig. 5 is a cross-section on line 5-5 of Specification of iii-otters Patent.

Serial No. 230,976.
of the general character disclosed in my prior iatent No; 1,2d2,367 dated @ctober 9, 1917, and my co-pending application Serial No. 163,824 filed April 20, 191-7, in that each plug is provided with a longitudinal blowod'and priming passage through which extends a movable and removable pin 26, serving the dual purpose of an electrode, and a means for normally sealing the blowoil passage. I
Mounted on the engine are standards 12, having pivotal connections 13 with carrier arms is, on the outer ends of which are journals 15 carrying a shaft 21. Collars 23 preclude the shaft 21 from longitudinal movement in the journals 15. Shaft 21 is polygonal in cross-section, and is here shown as pentagonal, to allow oi its being normally locked against inadvertent rotation by spring clips 17, carried by a rod 16, supported at its opposite ends in arms i l.
liiiounted on shaft 21 is a plurality of earns 22, here shown as spring pressed rollers. Each roller is precluded from longitudinal movement on shaft 21 by washers 29 and cotter keys 28, as shown in Fig. l. One of these cams is positioned to cooperate with each spark plug in such manner as to engage with the upper end of the movable electrode 26 to force said electrode down to its seat or to allow it to be raised so as to let the cylinder exhaust through the plug. Springs 18 serve to normally maintain the cams in cooperative relation with. the plugs through the maintenance of the arms 1% in the "full line oper ive position shown in Figs. iand But, if it is desired to remove a plug, or one or more electrodes 26, the arms 14:, may he hoc shifted on pivot connections 13 against tension of springs 18 into the dotted line positions of igs. and 5, to allow of J! r T' iree access to the plugs. W hen the shaft is in this inoperative position, the electrodes 26 may he rear ily withdrawn as shown in dotted lines in 5, to allow of manually cleaning or renewal of the same.
It will of course he understood that one rock shaft 21 is associated with each bank of cyl inders incase the invention is embodied in an engine of the V-type, as shown in the drawings, and, that in vertical engines having dual ignition, c'. 6., two plugs in each cylinder, there would he one rocloshait with its described adjuncts associated with each series of plugs.
Aside from the bodily oscillatory movement of each shaft 21 into and out of operative position, said shaft is adapted to be rocked by means of a handle 24, fixed thereto, to present different portions of the cams 22 to the plug electrodes 26. The several cams are set on the shaft in different relation so that,'as the shaft is rocked, the low points of the cams may be successively presentedvto the successive electrodes, for the purpose of allowing the exhausting of any particular cylinder through the plug.
Inpractice, the shaft 21 is made sulficiently long to project through the dash whereby the handle 24 is within easy access of a chauffeur or driver, and, may be manipulated by him at any time to allow of the cleaning of the plugs without necessi tatinghis leaving hisseat in the car.
The present invention may be used as shown and described on any type of internal combustion engine employing spark plugs, irrespective of the number of cylinders, it being understood that there will be as many earns 22 provided as there are plugs. Very good results however may be obtained through the conjoint operationof the device of this invention and the trouble locat- 7 ing device of my co-pending application No.
230,975, since, if it is found through such locating mechanism that the trouble is due to a short circuit at a plug, the device of the present invention may be manipulated to blow out such plug, and, if the short circuit was due to carbon, dirt or oil, the trouble will be rectified immediately.
Having thus fully described my invention,
what I claim as new, and desire to secure by Letters Patent, is
V 1. In an engine, a plurality of spark plugs, each of which is provided with a 3. In an engine, a plurality of spark plugs provided with valved blow-oil outlets, and unitary means for selectively controlling the outlets of all of said plugs.
4:. In an engine, a plurality of spark plugs provided with valved blow ofif outlets, means associated with, each plug for normally seating its valve, and controlling means, common to all the valve seating means, forallowing of the selective releasing-of said valves, whereby any particular plug may be blown out to the exclusion of the remaining plugs.
5. An internal combustion engine embodying a plurality of cylinders, each of which is provided with a spark plug having a movable electrodeembodying'a valve adapted to close the blow-off passage through the plug, and manually operable means for selectively controlling the operations of said electrodes from a distant point.
In testimony'whereof, l have signed my name to this specification. V c
