To all whom it may concern: a l

Be it known that 1 SAMUEL D. SHAKLEY, a resident of Pittsburg, (North Side,) in the county yof Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Explosive-Engines; and'I` do hereby declare the following to be a full,

clear, and exact description thereof.

My invent-ion relates to internal combustion A engines, and has special reference to thatform of engine known as the four cycle type.

The object of my invention is to providel a cheap, simple and efficient four cycle engine in which the cylinders of the same may be charged and scavenged with greater eiiieiency than the present form employed.

To these ends my invention consists, generally stated, in the novel arrangement, construction and combination of parts as hereinafter more speeiiically set forth and described and particularly pointedA out in the claims.

To enable -others skilled in the art to which my invention appertains to constructand use my improved internal combustion engine, I will describe the same more fully, referring to the accompanying drawings, in Which- Figure 1 is a' side elevation of the engine showing the distributer in section on tht` line :zem Fig. 2. Fig. 2 isa 'vertical sectional Fig. 1 Fig. 3 is a like section on vthe line 3 3, Fig. 1. Fig. 4 is a cross-sectional view of the distributer on the line 4 4, Fig. 1, with the valve at a different position. Figs. 5 and 6 are like sections on the lines 5--5 and 6*(3, respectively, Fig. '1, with the valve at different positions. Fig. 7is a longitudinal central section of another form of engine, showing the distributer applied As illustrated in the drawing,"A represents my improved internal combustion engine and such engine is provided with the cylinders 1 and 2 andmay be used in conneetion -with motor vehicles, such as automobiles, marine Wessels, etc. In each of the cylinders 1 and 2 of the r engine A theusual water jacket 3 extends around the same, and

such cylinders havepistons 4 operating thu-ein through piston rods 5 connected thereto and to the crank shaft 6 which extends through the crank cases 7 view of the engine on the line .2f-2,'

v outer valve casing 8 and 7 of such engine. At one side of and at the lower end of the cylinders l and 2 is the distributer B, and such distributer Iconsists of the outer valve. casing -8, within which is the inner circular valve is connected to suitable means.

.Rotatably mounted within the casings 8 and 9 of the distributer B is the cylindrical the cylinders 1 and 2 by any casing 9, and said distribute-r valve 10, and suchfvalve bears against the inner face of the inner casing 9 and is rota` table therein, while such valve is hollow and is provided at about its center with a wall 12 which divides said hollow center into the chambers 13 and 14. Extending through. valve spindle 15 which is the valve 9 is the secured firmly to said valve by its center wall 12 and such shaftis provided wit-h a spur gear or other means (not shown) for connecting the same to the crank shaft 6V through achain belt or other suitable connection for revolving the same.

The valve 10 is' provided with a concave portlonl extending into the chamber 13 within said valve and' a concave portion 17 extending into the chamber 14 in said valve and such Valve is also provided' with the openings 18 and 18 which are diametrically opposite each other and lead into and communicate with the chamber 13 therein, while the openings. 19 and 19"in said valve lead into and communicate with the chamber 14 and the openings'lSand 18 in said' valve are adapted to communicate at certain periods with an through the outer valve casing 8 and the inner valve casing 9, while the openings 19 and 19 in said valve are adapted to conimunicate at certain periods with the opening 21 which opening exten'ds through the and the inner valve casing 9 .inclosing said valve.

The outer and inner valve casings 8 and 9 are provided at-their lower end with the openings 22 and 22 extending through the sa-me and such openings are directly 1n line with the' concave ortions 16 and 17 respectively, in the va ve 10, while such casings are also provided at their upper 4side with the openings 23 and 23 extending through the same and such openings are alsoin line with the concave portions -16 and 17, respecopening 20 which extends tively, in said valve. At one end; ofthe 1 valve 10 and between the end wall of the outer valve casing 8 is a passageway 24 which communicates with the chamber 13 in said valve, while another passageway is formed at the other end of the valve 10 and end wall of the outer valve casing 8 which communicates with `the chamber 14 in said valve. A f

Extending from and communicating with the crank case 7 is a pipe 26 which extends upward therefrom and communicates with the passageway 24 in the valve casing 8,

valve'casing, and such chamber is adapted to y or other means (not shown) in its connec` In considering communicate with the openings 23 and 23 above the chambers 13 and 14, respectively.

The rear portion of the outer valve casing 8 is flared so as to form the'passageways 30 and 30 between said valve and the inner valve casing 9, and such passageyvays are adapted to communicate with the intake port 32 which enters the cylinder 1 through the water jacket3, while lthe outer valve casing 8 is also ared in the saine manner to form the passageways Bland 31, andA these passageways are adapted to communicate with the intake vport 32 which enters the cylinder 2 through the water jacket 3, and

the cylinders 1` and 2 are each provided with t vcylinder 2 is precisely the same as described an exhaust port 33 and 33, respectively, and such port in each cylinder is diametrically opposite to said intake port. On the upper end of each of the pistons-4 and directly in front of the intake ports 32 and 32 when saidl pistons are at their lowest position are the deiiecting lips '34, and such lips are located near said ports and extend -vertically from said pistons.

The use and operation of my Iimproved explosive `engine is as follows r-The crank case 7 is filled with the explosive mixture, as hereinafter described, and the crank case 7 is iilledwith air for scavengingl the cylinders 1 and 2 of the engine. 'The cranks on the shaft 6 are set at 180 degrees apart, and the engine being of the four cycle type, a ycompleteopera-tion is effected by four com- ,plete strokes of the pistons, or while the' valve shaft' 15' ismaking one complete revolution' through the medium of a Spurvgear tion with said crank shaft. the cylinder 1 and the crank case 7 attachedthereto the piston 4 is shown at its downward position and said cylinder .has just been .cleansed of the exploded mixture, and is now ready for a new charge. At this time the valve 10 is at a position as shown in Fig. 2, and the concave portion "16 on said valve will allow the mixture, coming from the crank case 7, through the pipe 2@ and chamber 27, to pass from the opening 22 into the passageway 30, and thence through the `port 32 into said cylinder.

i The piston now rises by the action of' thepis-` ton 4 in the cylinder 2 through the medium of the crank shaft 6, and'when the piston 4 in the'cylinder 1 has reached its raised position in said cylinder the mixture therein is exploded in the usual manner and said' piston is forced downward, thus opening the ports 32 and 33 in said cylinder. During this operation of the piston the 4valve 10 has been revolved one-half a revolutionV and the air, which has been compressed in the crank case 7 byV the downward stroke of the piston 4 in the cylinder 2, rushes-up through the pipe 28 and through the passageway 25, the chamber 29, andthe opening 23 in the valve casings 8 and 9. The. valve will now be in a position such as is .shown at F ig. 3, and the air will pass through the passageway 30 and thev port 32 and strike the deiiecting lips 34, which will, tendfto throw the air through the 'uppermost parts of the cylinder 1 and such air will then be exhausted through the exhaust port 33 and into an exhaust manifold 35 on the side of said cylinder, while the piston 4 in the-same will then be forced upward and will reverse and start downward and thus compress the gas or explosive mixture contained inl the crank case 7.

The operation of the piston 4 within the 105' except that such operation is one hundred and eighty degrees behind the operation of the piston in the cylinder 1, so that when the one cylinder is receiving its charge of mixture the other cylinder is being scavenged of the exploded mixture contained therein.

l/Vhen the concave portion 16 of the valve 10 is at a position such as shown in Fig. 4 or Fig. 5, and when the piston 4 is ascending in the cylinder 1, the opening 18 or 18 in the valve 10, which openings are diametricallyw opposite each other, will be over the `opening 20 in the valve casings 8 and 9 andthe'mixture will be vdrawn into such openings by this action and admitted to the crank case 7 throughthe chamber 13 in the valve'lO and the passageway 24 and lpipe 26 leading to said crank case, and in like manner air wiil be drawn into the crank case 7 when eitherA the opening 19 or 19 in said valve is communicating with the opening 21 in the valve casings 8 and 9, and such air will pass into `the chamber 14 and through the passageway 25 andthe pipe 28 leading .to said crank case, and when the piston in icoV ' pressed air from the crank oase 7" fao the communication of said openings will have been cut ofll so that the air or mixture in the crank case Will then be compressed by the dovvnvvard stroke of the piston. It will` th-us be seen-that .when the mixed explosive charge from the crank case 7' is passing into the cylinder l, the comis passing into the cylinder 2 and expelling the exhaust gases from the same intothe manifold 35,

and in like mannerwhen the .mixed explosive charge from the crank case 7 is passing into the cylinder 2 the cylinder 1 isv being cleansed by the compressed air from the crank case 7 as before described."

With the use of my improved internal combustionengine, such engine .must in all cases be of the four cycle type and must have two or more cylinders and suc'h lcylinders must be connected in pairs so that the alternating rocess of admitting 'explosive mixture and) accomplished, and it will be obvious that with my type of engine all springs and puppet Valves in the combustion chamber willbe entirely eliminated so that much inconvenience and annoyance `caused by such parts getting out lof repair 'will be done away with.

In the .regular four cycle type of engine employed in general use at this time a large amount of the ignited or exploded mixture remains in the combustion chamber after the exhausting operation so that when the new explosive mixture is admitted into such chamber it unites with the said remaining exploded mixture and thus renders the same exceedingly less efficient, While in the use of my improved engine all this trouble will be avoided by the automatic scavenging of the cylinder with compressed air to relieve the same of all exploded gases.

In the case of heavy duty engines of either the verticalor horizontal type, the latter of which is shown in Fig. '7, Where there is a chamber 36 at theend of each piston opposite to Where the combustion takes place and formed by the back Wall of such cylinder and said piston the pipe 26 Will communicate With the chamber 36 of the cylinder 1 and crank case 7, and the compression of the mixture Will be accomplished in such chamber, While the pipe 28 Will communicate Wit-h the chamber 36 of the cylinder 2 and crank case 7, and the compressionof the air Will be accomplished in sucli last named chamber.

-It Will be evident that rthe distributer of myim roved enginemay be operated by means rom the crank shaft other than those,l described and that various modifications and changes in the design and construction of the engine, the distributer and 'its operation may be resorted to,without departing from air for scavenging may be` chambers for the spirit of the invention or sacrificing any of its advantages.
