Patented May 8, 191'?.

Original application filed February 17, 1913, Serial No. 749,041. Divided and this application filed April 13, 1914. Serial No. 831,597.

To all ll1/tom t may concern.'

Be it known that I, FREDERICK E. Ror- RIGHT, a citizen of the United States, residing at Interlochen, in the county of Grand Traverse and State of Michigan, have invented a new and useful Igniter and Valve Mechanism, of which the following is a specification.

The device forming the subject matter of this application is an internal combustion engine, and one object of the invention is to provide an engine of this sort, in which two v cylinders are located upon opposite sides of the crank shaft and coact to impart rotation thereto, thereby increasing the power of the engine.

Another object of the invention is to provvide an internal combustion engine which will operate without jarring and in a balanced condition.

A further object of the invention is to provide novel means for timing the explosion and for controlling the exhaust. The invention aims to provide novel means for controlling and regulating the character of the explosive mixture.

It is within the scope of the invention to improve generally and to enhance the utility of, devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combina@ tion and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise lembodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit ofthe invention.

In t e accompanying drawings Figure 1 shows t-he invention in side elevation;

Fig. 2 is a side elevation, the view point in Fig. 2 being 9()c remote from the view point in Fig. 1;

Fig. 3 is a longitudinal section of the cylinders, parts appearing in elevation;

Fig. 4 is a sectional detail showing't-he mixing chamber and associated parts.

The engine herein disclosed may be used as a stationary structure or as a marine prime mover, and may be disposed either horizontally or vertically. In the following description, it will be presupposed that the engine is placed vertically as shown in the drawings, the terms upper, lower7 and the like being selected accordingly.

In ca rrying out the invention there is provided an upper cylinder 1 anda lower cylinder 2 united by a tubular connection 3 as will be understood best from Fig. 3 of the drawings. Formed upon the lower end of the lower cylinder 2 is a frame 4 cooperating with a base 5 to form bearings 6 in which is journaled for rotation a shaft 7 carrying a fly wheel 8 and provided in its intermediate portion with a crank 9. A pitman 10 is connected with the crank 9 and is pivoted to a piston head 11 which operates in the lower cylinder 2, there being a piston head 12 in the upper cylinder 1, the piston heads 11 and 12 being connected by a rod 14 mounted to slide in the tubular connection 3 between the cylinders. The rod 14 may be surrounded by packing rings 15 cooperating with the tubular connection 3.

To the cylinders 1 and 2 are secured guides 16 in which is mounted to reciprocate a rod 17 provided at its lower end with an eccentric strap 18 surrounding an eccentric 19 secured to the shaft 7. The lower end of the upper cylinder l is provided with an exhaust port `20 and the upper end of the lower cylinder 2 is provided with an exhaust port 21. The exhaust port 20 is controlled by a spring-closed valve 2 and the exhaust port 2l is controlled by a similar valve 23.

Secured to the rod 17 and projecting inwardly therefrom are arms 24., adapted respectively to engage successively with the valves 22 and 23. Secured to the cylinders 1 and 2 are brackets 25 constituting fulcrums for levers 26. Inwardly projecting Fingers 27 are mounted to slide upon the rod 17, compression springs 28 abutting against the fingers 27 and abutting against the superposed guides 16. As indicated at 29, the rod 17 is shouldered below the fingers 27. The construction therefore, is such that when the rod 17 is elevated, the fingers 27 will be elevated ofi' the levers 2G. When, however. the rod 17 descends. thc springs 2S will expand, holding the fingers 27 in contact with the levers 26. From the foregoing it will be observed that the lingers 27 and the levers 26 constitute a` switch aitfording a make and break mechanism whereby the successive charges in the cylinders l and 2 may be ignited, any suitable spark plug mechanism and corresponding parts being resorted to as is common and well known in the art.

The parts 2G and 27 may carry Contact terminals T insulated from the respective parts as shown at l. Any suitable means, however, may be provided 'tor insulating the parts 26 and 27.

The inner ends of the levers QG are pivoted to links 30 which, in Ytheir turn, are pivoted to a walking beam Ill, supported intermediate its ends upon the upper cylinder l as indicated at 39.. standing from the walking beam 3l is a handie 83 adapted to be engaged by a segment 34 which is secured to the upper cylinder l.

Secured to the shaft 7 is an expansible, spring retracted wheel 235 adapted to coact with a shoe 3G secured to the lower end oi a governor rod 37 mounted to slide in brackets 3B which aresecured to the lower cylinder 2. compression spring 39 is interposed between one bracket 38 and the shoe 36 to eii'ecta depression of the shoe and to cause the shoe to cooperate with the expansible wheel 35.

Extended between the cylinders l and 2 is a pipe l() whereby the explosive mixture is conveyed to the cylinders. lnterposed in the pipe 4l() are valves 4l which open, respectively toward the cylinders l and 2. Connected with the pipe l0 intermediate its ends as shown in Fig. l is a tubular mixing chamber l2 the inner end of which is counterbored as indicated at #t3 adjacent the pipe 40. Projecting into the mixing chamber 4t2 is a gasolene inlet pipe 4.4-, provided with a seat 4,5, adapted to be engaged by a needle valve 4G threadedinto one end of the mixing chamber The. mixing chamber l2 'is supplied with a depending air" inlet pipe 47 in which is journaled for rotation an air control valve d8. Secured to the outer end of the needle valve 4-6 an arm nl) united pivotally by means of a link 50 with the governor rod 37. The outer end of the air control valve 4:8 is provided with an arm :El which is pivoted to a link 100, the latter being pivotcd to the upper end of the rod 37.

The invention further includes a tank 52 located adjacent the lower cylinder and adapted to contain air under pressure. iin upright pipe 53 is located above the air tank 52 and connects therewith, the pipe 53 being provided with a branch 5l which enters the upper cylinder l. The pipe 53 is further providedl with a. branch 55 which enters the lower cylinder 2. At its upper end, the pipe 53 may be equipped with a Secured to and up Leather vent 5G controlled by a. valve 57. At the point where the branch enters the pipe 53 there is placed a rotary valve 5S, a similar rotary valve 5S) being located at the juncture between the branch 55 and the pipe The stems of the valves 5S and 59 are equipped with cranks (i0 and the cranks are connected pivotally by a rod (il, the upper end ol' which upstands to afford a handle G2.

When the shaft 7 is rotated, the eccentric 19 thereon, cooperating with the strap 1S, will eflect a raising and lowering of the rod 17 in the guides 1G. Ars-thc rod 17 is raised and lowered,'the arms 2l will coperate alternately with the valves QQ and 23, thus opening the exhaust ports 20 and 2l of the cylinders 1 and 2. When the rod 17 reciprocates, the lingers 27 will have make and break relation with respect to the levers 26, as hercinbeliore set forth, explosions in the cylinders l and 2 being thereby effected.

As hcreinbeitore set forth, the explosionsI may be timed by moving the handle 33 upon the segment 3l thereby tilting the levers through the medium of the walking beam 3l and the links 30.

Should the engine begin to race, the wheel 35 which is carried by the shaft 7 will eX- pand, coaeting with the shoe 3 and effecting a raisin g of the governor rod 37. When the governor rod 37 is raised, the link 50, coacting with the arm 49, will cause a rotation of the threaded needle valve 4G, the

same approaching` or entering the seat d5,

in the gasolene inlet pipe 4.4. it the same time, the rod 37 through the medium of the link 100 and the arm 5l will rock the `valve t8 which is located in the air inlet pipe 47, thereby controlling the air supply. ln this manner, the speed of the engine will be accurately and positively governed. y f

rIhrough the medium of the handle (32, the rod 6l may be actuated, the same operating the cranks (30, and controlling the valves 58 and 59 in the pipe 53, connection being thus established between the pressure tank 52 and the cylindersI l and 2, through the branches 5i and respectively. The operation above described alfects the character oi" the explosive mixture, at any desired time. Further, the air under pressure, contained in the tank 52 may be used to start the engine, canking being unnecessary.

The explosion chamber of the upper cylinder l is located at the lower end thereof, the explosion chamber of the cylinder 2 being at the upper end of the said cylinder'. ly this construction, the crank 9 is subjected to equal pressure upon opposite sides et the crank shaft 7 and the engine will operate withoutjar and as effectively as an engine employing steam.

QbViOtiSly, the tank 52 may be pumped up frein the cylinders l and 2.
