Another object of this invention is to provide an interrupter assembly for use in the distributor mechanism of relatively large internal combustion engines, wherein the volume of explosive mixture is'such as-to require a plurality of spark plugs for each .cylinder to ensure the best combustionresults, which interrupter. structure embodies a. plurality of contact makers and breakers corresponding in number to the number of spark plugs required, which contactsare operated in unison to provide simultaneous spark forming energizing of the spark plu In some power stations, particular y those utilizing that type of internal combustion engine known as gas engines, the air is impregnated with the combustible gas and to prevent accumulation of' such gas in the distributor and to permit inspection of the interrupter assemblies while in operation, the easing of the distributor is sealed with a transparent cover, and means are provide to per-' mit, at will, the passing of fresh air, under, pressure, through the distributor casing.
With these objects .in view, the invention consists in various fe'atures' of construction and combination of parts, which will be first described in connection with the accompanying drawings, showing a spark distributor ofthepreferred form embodying the invention, andthe features forming the in-v vention will bespecifically pointed out in the claims. 1 V
' Fig. 1 is afront elevation of the distributor.
Fig. 2 is a top plan of the distributor.

1928. Serial No. 280,408.
Fig. 4 is a section through the distributor 1 taken on the line 4-4 of I! ig. 3.
- Fig. 5 is a detailed section through the dis-v tributor taken on the line. 5-5 of Fig. 1.
Referring more particularly to the drawings, the improved spark distributor comprises a casing 1, which has an annular ring 2 on the inner side or back thereof which fits within the adjustment ring 3. The ring 3 is attached in any suitable manner to a part of the engine with which the distributor is used, preferably to the bearing 4 of the cam shaft 5 of the engine, and the end of the camshaft 5 projects into the casing 1.
An operating pin 6 is carried by the cam shaft and projects beyond its end into the casing .1 for operating the cams of the interrupter assemblies 7. An interrupter assembly 7 -is provided for each of the cylinders of the engine as for example, in a 4 cylinder engine there will be 4 interrupter assemblies. All of the interrupter assemblies are the same, or similar in construction and each of them comprises a pair of contactmakers and breakers 8 01? any approved construction mounted upon opposite sides of the axis of the interrupter assembly. The contact makers and breakers orcontacts 8 are operated by a cam 9 which has, in the present instance, two operating surfaces 10 thereon, one for each of the contacts 8 and'these surfaces 10 are arranged so that upon oscillation of the cam 9 the contacts 8 will be' simultaneously operated to energize two s ark plugs simultaneousl v The present spar distributor is primar' y for use .on large internal combust on engines in which the volume of gas or ex-- plosive in each cylinder is so great that it is advisable to use two or more spark plugs to ensure the best combustion results in the engine. The two contactors'8 are provided to permit simultaneous sparking of the two spark plugs in each cylinder.' The cams 9' a are rockably mounted in suitable/bearings 11 and they have operating levers 12 connected thereto which project into the path of the operating stud or pin 6, therefore duringthe rotation of the cam shaft 5' the stud 6 will successively engage the levers 12 of the various interrupter assemblies 7 and operate the cams in sequence for proper firing of the cylinders of the engine with which the spark distributor is used. When the stud 6 engages and moves one of the levers 12, the cam 9 to which the lever 12 is connected, will be oscillated or operated nected to.suitable bosses 16 formed on the lever and to studs 17 mounted upon the interrupter assembly carrying bar 18. The return of the lever 12 to its normal position will move the cam 9 in a reverse direction, returning it to its normal stationary position in which it remains until the lever is again moved by the stud 6. The provision of only two flats or operating surfaces 10 on each of the cams 9 will prevent the occurrence of a spark should the engine, equipped with the improved spark distributor, turn backwards.
Independent adjustment of the interru ter assemblies is permitted, since 4 cycle double acting engines require separate or independent adjustment of the ignition of each cylinder end in order to obtain the best balance of power between the cylinder ends. For this purpose, each of the interrupter assemblies 7 1s mounted upon a sliding bar 18 which is adjusted by means of adjusting screw 19 thereon through the casing 1. The sliding bar 18 is held in adjusted position by means of. a lock nut 20. The'sliding bars supporting alternate interrupter assemblies overlap at the corners ,as shown at 21 and are held against rotation on their longitudinal axis by means of springs 22, which serve not onl this function, but also the function of holding the heads 23 of the clamping T bolts 24 tightly against the ring 3 for attaching the'distributor structure to the attaching rin 3. The sliding bars 18 are provided with slots 25 to permit their adjustment over the T bolts 24. By adjustment of the respective adjusting screws 19, the position of any one of the interrupter assem lies 7 may be adjusted relative to the otherinterrupter assemblies to vary the point of contact ,of the stud 6 with the respective lever 12.
The nuts 27 and the springs 22 on the T bolts 24 are adjusted to provide suflicient tension to partially holdthe casing 1, and a fifth T bolt 28 is provided for rigidly clamping the casing 1 to the attaching plate or ri-n 3 by means of the hand wheel 29. The bolt 28 has a tensioning spring 30'mounted thereon and is similar to the T bolts 24 except that it has the hand wheel 29 thereon to permit the easy release of the clamping tension of the head 31 against the attaching plate 3 for the purpose of permitting movement or adjustment of the casing 1 and all of the interrupter assemblies 7 in unison for advancing or retarding the entire ignition of the engine. After the tension of the head 31 is released by turning the hand wheel 29, the casing 1 is rotated by means of the handle 32 which is carried thereby.
A suitable indicator, of any approved type, as shown at 33, may be provided for indicating the adjustment of the entire assembly for advancing or retarding theientire ignition of the engine. In the drawings, this indicator 33 comprises a late 34 carried by the casing 31 and an indicating finger 35 carried by the attaching ring 33. I
The outer side or front of the casing 1 is closed by a transparent cover 36, which may be plate glass or any suitable material, and this cover 36 is tightly clamped in place by a clamping ring 37 and clamping screws 38, and it is sealed .by suitable sealing gaskets 39. This sealing is desirable, particularly when the spark distributor is used in connection with engines embodying natural or byproduct gases as combustible fuel, because in such instances, the air surrounding the engine is usually heavily impregnated with the combustible gas, and it is, of course, undesirable to permit such gas to enter the distributor casing 1. To ermit flushing of the interior of the distri utor or to provide that the interior of the distributor always has fresh clean air therein, and also to prevent gas impregnated air from entering the easmg, the casing 1 has a nipple 40 connected thereon which is adapted to have connection with the air hose to permit air under pressure to be forced into the casing 1. A relief valve 41 of any approved construction is carried by the casing 1 at a point remote from, the nipple 40 so as to permit circulation of air through the interior of the casing, and prevent forming of excessive pressure in the casing, while allowing a ressure in excess of atmospheric pressure to e maintained therein.
From the foregoing description, taken in connection with the accompanying drawings, it will be apparent that a spark distributor for use in connection with internal combustion engines has been provided, in which simultaneous operation of a plurality of contactors or of circuit closers is provided by the oscillation of an operating cam, to simulta-' neously energize a plurality of spark plugs, and also that novel, practicaland simple constructions have been developed to provide for independent adjustment of any one or all of the interrupter assemblies, to provide proper balancing between the cylinders, and also means to permit simultaneous adjustment of all of the interrupter assemblies for advancin or; retarding the entire ignition system the engine.
