i Thel object of this invention is to provide meanswhereby the mechanism for distributingthe electric spark to a foniwzylinder engine may be inode to supply the necessary ignition. -'or a `sin-cylinder engine synchro nouslT with :the explosive Vperiods of the re- "speetive` Aeylinders, and to provide means Wl'iereby the devi-ee -niay be adinsted 'at `will to distribute to a four or a Six-cylinder engine.

minal of the the transe other teri` -breakerthrough the conductor 44, spring .point on the other member' 47, which member 47 is rounded with the body of the machine. T ecircuit is completed through the body 32 of the armature which is connected at 48, (see Fig. 2), With the other terminal of the armature winding.

The member 47 of the circuitbreaker is here shown asa lever pivoted at 50, and having a lug 51, which extends through the casing in which themechanism of the circuit breaker is mounted, and into the path of the bent ends 52, of a rotary arid diametrically mounted arm on the sleeve extension 53 of the armature, whereby the circuit is broken twice ateach revolution of the i terminals vbeing' grounded to the machine,

armature at 'the maximum point of intensity of the electrical impulses which are being generated. The lever 47 is held normally in contact by means of a spring 54. A con denser 56,.(see Fig.. 2), is bridged across the terminals of the circuit breaker, one of its and the other terminal being connected at 58 with the spring bar 45. The purpose of this condenser is to intensify the inductive' influence in the secondary winding, and to reduce sparking between the platinum contacts of the circuit-breaker. 1Wound upon the soft iron core 30 is the primary winding of the transformer 43, and outside of this primary winding is the secondary or A high tension winding of smaller wire, one

terminal of whichl is connected. by the conductor 42 with the upper journahbearing of the armature, as previously described, and the other terminal of the secondary winding is connected with a spring conductor 5 9, which is electrically connected with the binding post 60.

A The bindn post 60 is connected by a con4v ductor 61 Wit a 'binding post 62 of the distributer mounted in the cap of our machine. This binding post has a .stem' which is pressed by spring 64 into constant contact with a -spring plate 65, the outer end" of 'which plate (55 is made to sweep the'segments (3(3 mounted on the inner side of thel cap t7. The cap 67 yisa non-conductor while the segments are conductors', the area of which are shown by dottedA lines in Fig. 1. 'lhese segments are electricallyconnected with the binding post 68,:v from which the current is conductedto the engine cylinders in the usual manner.

It will. be understood from What'has been said that the1 circuit is broken twice on cach revolution .of the armature, so that for each complete sweep or'cirouit of travel of thespring-plate G5 against the four' segments (3G in circuit with the four engine cylinders, the armature must 'have made. two complete This terminal 46 revolutions. To accomplish-this mechanically we provide a spurgear Wheel 72, which is here shown as having itsarbor 73 lrevolublyinserted within the hollow sleeve 53 of the armature where its notched lower end is lockedA by engagement with a cross bar 74 to cause the gear wheel 72 to rotate with said armature. Thewh'eel 72 is mounted within a gear case 75 having circular walls, and also mounted in said gear case is a ring 77 with internal cogs. This cogged or toothed ring 77 is just twice the diameter of the wheel 72, and the latter is. drivingly connected with said annular gear by the intermediate pinions 78. It is thus obvious that the ring '77 will rotate oncefor each two revolutions of the spur-gear wheel 72. Mounted in a ixed, but removable manner on the toothed ring 77 is a plate 79, and upon this plate a block of insulation 80 is mountf ed and upon the block is a springfbar 65. By the above arrangement the spring-bar will make one complete revolution .or sweep at each two revolutions of the wheel 72 and its armature. Now, by mounting the two intermediate pinions 7S on va ring 82, which may be released by removing lthe holding screws 83, said ring, being mounted in a suitable roove in the bottom. of the gearcase an by locking the toothed ring 77 to the side' of the gear case by inserting a screw in the hole 86, (see Fig. -3),'and also by releasing the plate 79' from said toothed ring 77 and securing the plate to the lugs 84 of the ring 82, the intermediate pinions 78, when rotated by the gear Wheel 72, will roll back on the toothed ring 77 to a certain extent, so that the resulting forwardltravel of the plate 79 will amount to one com lete revolution to each three-revolutions o the armature. Six electrical im 'ulses or sparks will be developed under this ast adjustment, at each revolutionof the plate 79, and will be conducted through thewire 61, to the spring plate 65, carried by the plate 79. These impulses will 'be evenly. distributed cylinder engine. The drawing'shows a' cap to six segments, if same are provided in the i with binding posts and segments for a fourcylinder engine, and for av six-cylinder engine this cap will have to be replaced by one having six segments and a .corresponding number of binding osts.

' The relation of one-ha f diameter between the wheel 72 and internally toothed ring 477 j against vrotationbybeing fastened to its lio i n ments, and six binding posts, six cylinders i conditions herein first described.

' shaft, a distributer comprising a plur'alit-y iinagneto, siX electric impulses will be developed during each revolution of the plate us, we do not desire to be limited to this ex- 4`1. The combination, with an electric curwith said spur-gear, an annular plate on case, and the plate 79 is released from the ring 77 but is fastened to the ring 82 on which the intermediate pinions 78 are mounted, there will be a loss in the advance movement of the plate 79 which will require the wheel 72, (and the armature to which it is attached), to make three complete revolutions for each single revolution of the plate 79. Consequently, with our 79, and by providing a cap with six segmaybe connected and sparked with the same Veiiciency as four would be under thev While `we have shown the preferred embodiment of our invention as now known to act construction and arrangement of parts, but

" What We cla-iin as new and wish to secure by Letters Patent, is-

rent producing apparatus, of a distributer comprising a` plurality of insulated annularly arranged segment-conductors, a traveling4 Yconductor adapted to sweep all of said segments'ateach circuit ofits travel, a driving shaft, and means between-the driving shaft and traveling conductor for varying the*` r lative travel of said shaft and condnctor.

2. The, combination with an electric current pr'ducing apparatus, of a. drivingshaft, a distributercomprisiig a plurality of insulated annularly arranged segment-conductors, a traveling conductor adapted to sweep lall of said segments at each circuit of its travel, a planetari)7 system of gears transmitting rotary trave from the driving-shaft to said traveling conductor, and means c0- operating with said gears forvarying the relative travel of said driving-shaft and conductor.

The combination with an electric spark producing apparatus, of a driving ot' insulated annularly arranged segmentcoi'iductors, a traveling conductor adapted to sweep all of said segments at each circuit of its travel, a plate on which the traveling conductor is mounted, a spur-gear mounted on the driving shaft, an annular internal gear concentric with and of twice the diameter ingly connecting said annular internal gear means for lockin 'gear to the casing,

which said intermediate gears are mounted, immovable and releasing for movement said internal gears and said annular gear vcarrying plate, and means at the time said annular gear carryin plate is locked and said internal gear is released of securing the plate on which the traveling conductor is mounted to said annular intei-nal gear whereby they will both be free to travel, and means for locking the traveling conductor carrying plate and said annular gear carrying plate together wheii said internal gear is locked and said annular gear carrying plate is released, whereby, by the above changes in fastenings the traveling conductor will make one complete circuit for at least two revolutions of the driving shaft or for each three revolutions of the drivin shaft, respectively.

Ll. In an e ectric spark producing apparatus, a distributer comprising a plurality of insulated segment-conductors arranged in an annular series, a traveling conductor ,adapted to sweep all of said segments at each circuit of its travel, a. plate on which. the.,u
