To all whom' it may concern: 7

Be it known that I, Anocrun Oneness, e citicenlof the Republic of France, and a 1:esi-

eve invented certain new and useful Improvefbr Explosion-Ention.

This invention relates to a device for producing ignition and v ders. By the use of this device the circuit of any one of the igniters me. be maintained while'thecircuits of the ct era are broken, each cylinder observed alone.

, The invention isillustreted in the accome 1 shows the device in crosssection;

Fig. 2 shows the, same partly in lo section and partly in elevation. 3 is a cross-section through -a. modified cm of the device. Fig.4 is e diagrammatic view showing the connections between the controlling device re resented'ct A, the body M of the driving-0y 'nders, the induction-coils, and the accessory parts. Figs. 5 and 6 are a' section. and plan, respectively, of another embodiment of the invention.

For verifying or determining which, if any, is running without explo' sions an is thus a dead load on the engine a number of circuit-breakers are used, one beoonnectedto the ignition-circuit of each s the circuit of all but t e first cylinder the engine will stop or will continue in motion, according as this c lor proper y.

.itudinel Similarly each of the other cy tested in turn.

Means are provided also for ccmplelinglihe circuit of sec lot the igniters by a path w 'ch passes around the usual interrupter and is the positionef the latter or of the of the engine. Thus if. by the testing mechanism it be found that any one of the cylinders is running idly or without ignition a suitable buttonmey be pressed to cause ignition insaid cylinder by 7 way of a. shunt-circuit around the usual ciris stopped, b

4 mder which is in conspression ignition may be effected insaid cylinder.

t erunnm of 'theengineb explosion-engmes'hcving two or more cy y the circuit would be through wire 7) inders rnsy be 7 fthe contact 1 of t the proper moment as determined by the inran ed four testers or connecting members in t e nature of brid es and eds. ted for breaking the circuits 0% end as hereinafter explained, to seperetely verify the running of each of the c inders of the motor by bearing upon the knobs C, which are arranged at the u per portion outside the casing. Each of t ese rods or testers B is insulated from the mass of a lower socket or sleeve of ebonite a and also by means of its knob C, which is of insulating material. This rod B is in contact, by means of the pins 0, Fig. 2, with two strips?) l) which form two terminals in the primary circuit of en igniter. The stri' s of one series communicate, throu 11 wires with the automatic interrupter ,and the strips t of the other series are respectively connected, through wires b, (see Fig. 4,) to the terminals 1 l I P of the induction coils X X X K, respectively. Y

When one of the knobs C of the controller is depressed, the circuit is broken, because the pin cleaves the strips 1) b. The igniter of the corres ending driving-cylinder is thus cut out o circuit. Now if any three knobs be do ressed simultaneously the igniter of the cy inder corresponding to the fourth knob will be the only one on a complete circuit, and if the operation of the engine is defective under these conditions it must be that the operation of this cylinder is defective. For example, supposing the knobs C, C, and C to be depressed then, as indiceted in Fig. 4, 7 from the battery to P, thence through the riinelg circuit of X, (the other circuits eing roken,) thence button C and bi wire h and tenninal b to e interrupter K thence (at dicetor and circuit-closer 'i on the shaft of the engine) to the central shaft and through wire I) to the engine M and beck to the battery. At the same moment the the seconds? circuit of the coil X causes an o eretion o 7 the correstpondin igniter us each cylinder may e teste or its operating verified and the cylinder of which the operation is defective may be readily ascertained. V

For starting the motor four other phase, Fig. l,provi ducting material, are errangedu of the casing andin electrics on the front the severe igniters and terminal 3 to the first induced current 111 ed with knobs D, oi non-con connection, (through the springs m, Fig. 1) with the en-.

IIO

gine M, as indicated by the Wire m, Fi 4. his circuit is by way of the body M, Iiattery, connecting-point P and correspondin primary coil, wire I), stri b to rod B throug pin c. Thus if when t e motor is stopped one of these knobs D is depressed the circuit is closed by the end of the contact-pin d, carried by D, touching the rod B, and a spark is caused to ass in the corresponding ignition device is 1?, k or it whenever the shaft is in the proper angular position, as indicated by the interrupter K. The secondary circuitls from the igniter through the secondary winding of one of the coils X X X X and back to the body of the engine.

The interrupter K comprises a fixed disk and a central shaft driven by the engineshaft and making connection through the circuit-closer & successively with the four contacts on the disk. As there is never more than one cylinder which is in the phase of compression of the gaseous mixture and as it is necessary to know which this cylinder is in order to produce the spark there, the part i. is used as a combined contact member and indicator, bein mounted upon the shaft and forming part 0% the interrupter K and showing the

number

1, 2, 3, or 4 of the knob D which should be depressed. The knobs C may also be used for startin In this case (see Fig. 3) the stri s b are cut away from the rod at the midd e point of their length' that is to say, at o. T e rod normally stands in its highestposition with the pin in contact with the ends of the strips b b. When lowered to the middle position illustrated, the contact is broken. When the rod B is deressed to its fullest extent, it makes contact its biid o the en ine by its owest part at m.

T e device ascribed above for controlling the ignition of the cylinders renders it possible to operate with only one two, or three cylinders, if desired. It is only necessary to press upon a suitable number 0 knobs C so as to interrupt the electrlcal communication for the corresponding cylinders.

The device shownin Figs. 5 and 6 consists of a disk of insulating material E, in which areformed concentric grooves for the reception of circular conducting-strips (1, connected-in pairs to the conductors forming the circuits of the four cylinders. They are eight in number and are hereinafter designated by their numbers. These strips or blades are arranged in such a manner as to be capable of connection in pairs 1 2, 3 4, &c., by means of a transverse bar 9 h, of insulating material, carrying metallic contacts or rubbers I I I Z, coming into contact with the conductingstrips d upon the disk. This bar is in two arts 9 and h and :otates around its axis I The one part g, by means of a spring ,is given a flat bearing upon the circular con uctors d, numbered 1, 2, 3, 4, 5, 6,7, and 8.

pin 0 with the stri s b and with the The metallic rubbers l l l l establish communication between the conductors as follows: Z between 1 and 2, 1 between 3 and 4,

1 between 5 and 6, and l between 7 and 8. In this manner the four circuits are closed individually and can only be opened by an anular movement of the cross-piece garound its axis 1. The other side it is also movable around the same axis I; but it is articulated or movable at O and maintained in its raised position by means of a sprin r.

The circular conductors d orm together a continuous contact during about one-third of a rotation of the bar 9. By continuing this movement still further the current is only closed from 1 to 2 when the bar lies Within the angle y. The three other circuits are open. One cylinder only is therefore operat- In three successive angular positions are arranged contacts 6, connecting the con ductors 3 to 4, 5 to 6, 7 to 8. When the bar 9 is turned to overlie any one of these airs of contacts, the corresponding rubber establishes communication and ignites the corresponding cylinder. These contacts, as shown,

. are connected below the face of the disk with the conductors d. It will therefore be a parent that in order to verify successive v the operating of the igniters of the four cylinders it is only necessary to bring the movable bar 9 upon the corresponding contacts by turnin it either by means of a knob or handle, w ereupon thecylinder which does not ignite is indicated.

In order to produce ignition, the pivoted portion h of the bar may be employed. For this ur ose the conductors d are rolonged circu ar y beneath the face of the isk E and are connected each to two contacts f, said contacts being in successive pairs around the plate and being all in ositions such that when the said part h of t e bar is above anyv pair of these contacts the other part 9 invariably closes the fourcircuits; A circular conductor '0, connected to the bod of the en inc, surrounds the portion of t e plate which carries the contacts 1' serving for the ignition.

When the pivoted part h of the bar is depressed upon any two of the contacts its metallic portion connects that one o the conductors d, Fi 6, which comes from the primary coil the body of the engine, and thus com letes the primary circuit. (See Fig. 4.) he spark passes in the correspondlng cylinder and the motor after being started continues to rotate, since the part fr diametrically opposite always closes the our circuits. Any izylinder may be ignited in this manner. e bar may also be moved to a osition in which none of the circuits is comp etc, but all are interrupted.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare that what I claim is- 1. In a multiple-cylinder explosion-em gine, the combination of igniter-circnits tor the several cylinders, testers in said circuits, and springs tending to hold said testers in position to maintain said circuits com lets, said testers being independently opera is to break their several circuits and thereby permitting of determining, by operatin all but one of the testers, which, if any, cy inder is defective.

2. In a multipie-eylinder explosion-engine, the combination of ignitcr-eircuits for the several cylinders, terminals 3: b in said circuits, testers B independently operable, one for each air of terminals, adapted in one position to ridge said terminals and complete the circuit, and in the opposite position to open the circuit, and springs tending to hold said testers in positionto complete the circuits, said testers erlnitting of deter-mi in by moving all ut one, which, if any, cy inder of the engine is defective.

3. In a multiple'cylinder explosion-engine, the combination of igniter-circuits for the several cylinders, testers in said circuits, s rings tending to hold said testers in position to maintam said circuits complete, said testers independently erable to break their several circuits and t ereby ermitting of determining, by operati all ut one of the testers, which, if any, c fiinder is defective, and a hand-controlled evice for completing the prime circuit of any one of the igniters at will w ion the engine is not running, 7

4. A device for verifying or controlling ignition of the cylinders of explosion-engines, comgrisin in c0mlnnation, a plurality of in open ently-operable testers one for each cylinder and each provided with a connecting member normally connecting two terminals in the primary circuit of one of the igniters, said members ermitt' of determining, b moving all lint one 0 said members, whic if any, 0 linder of the engine is defective, and means whereby the farther movement of said mem bers completes the primary circuits and produces ignition.

In witness whereof I have hereunto si ed my name in the presence of two subseri ing witnesses.
