andli cylinders as follow I v to l) s; supplied with'a "series of po ts 1 Foil i a I I .1, --1ngs or holes extending from side to\ s1de "through the diskand in-the. Walls of the casing there are other ports 19and 19*which are so spaced as to permit respectively the intake of the explosive mixture and the expulsion of the exhaust at the appropriate time, depending upon the special construction of the engine, as will be hereinafter described. The fuel supply andexhaust pipes connect with these openings or ports-19 in the casing as shown. The explosive mixture is conducted to'the cylinders through conduits or ducts as follows (see F igs. 1, 2 and 3). 20 is the supply pipe for" the explosive mixture, which .of course connects" at one end with the carbureter. Near the cylinders,

it branches to right and left as shown in Fig. -3. One branch 21. connects with the appropriate port 19' in the casing 22, as

shown, and discharges through" one of the ports in the disk 15, when-it properly registers-with the said opening inthe casing, thence through the opposite walls of the casing and thence being conducted by a conduit discharges into the left hand cylinder, all as shown in Fig. 3. The other branch 24 of the fuel supply pi e similarly connecting with appropriately located and registering openings or ports in the disk casing and disk and conduit 25,-discharges at 26 into the right hand cylinder. The exhaust ports are similarly arranged, that is to say: 27 is the main exhaust pipe which likewise has two branches, one 28 (see Fig. 3) after connecting with suitable openings or ports in the disk casing and disk, c'onnects at 29 with the left'hand cylinder and the branch 30 similarly connects by a passage 31 with the right hand cylinder. 3i.- is a water supply pipe and 32 and 33 are water outlet pipes for the cooling system. 34 and 35 are spark plugs.

The operation of the apparatus is illustrated diagrammatically in Figs, 4 to 11. Figs. 4, 5, 6 and 7 illustrate the revolving disk and co-acting parts and the manner in which the equally spaced ports 18 in it are made to intermittently register, with the intake port 19 and the exhaust port 19 in the disk casing, which are, as above stated, suitably connected with the cylinders. In Figs.

4 to T. both'inclusive, for simplification in explanation, the parts are shown as applicable to a single cylinder. In Figs. 8, 9, 10 and 11, the disk' is represented as projected in a straight line and'the appropriate intake. and exhaust openings through the casing connecting with the cylinders are also shown and especial attention is called to the fact that in these last named figures (S to 11 both inclnsivel the parts arex llustrated as applied to a pair of cylinders;-

Referring now to Figs. 4 to Ii, and bearing in mind that the port 19 represents the intake opening through the casing, which connects with one of the cylinders and that the port 19 represents the exhaust port u from the samecylinder, it will be noted, .by' refer:

ence to Fig. 4', that the two uppermost ports- 18 which are .inereopenings or holes made directly through the revolving disk, are 50 disposed that (the diskrevolving in the direction of the arrow). the right hand upper port has just ceased registration' with the exhaust port 19 in the casing and that the piston 7 of that cylinder is at its uppermost the disk 15 being inrgcontinuous revolution,

that the right handarpper port 18 in the disk has passed away from the exhaust .port 19 and that the upper,,.left hand port 17 has made a transit completely across the intake port 19 in the chsing, during which movement of the parts, the descending piston 7- has drawn in to the cylinder a fresh charge of explosive mixture.

Referring now to Fig. 6, it will be seen that the crank shaft has made a complete.

revolution and that the piston is againv at its uppermost position, during which it has effected compression of the charge and that during this operation there was no escape. of the charge from the cylinder possible hecause both of the upper ports 18in the disk have during the upward movement of the piston, been entirely 'outof registration with either of the ports19 and 19 in the casing. Upon the completion of the compression of the charge, that isi'fto say, when the piston commences its second downward movement,

is seen again at its lowest position. Now in order that the exhaust of the products of combustion from the cylinder may be again efiected, it will be 'observed'that the port 18 in the disk 15 whichihad previously been the intake port, is now just commencing'to regis-. ter with the exhaust port 19, so that it now becomes the exhaust port, and furthermore that the port 18 which is now farthest to the left, as shown in Fig. 7 and which formerly was an. inactive port, it then being in the lower portions of the disk, has now moved inwardly, so that upon the return or exhaust movement ofthe piston 8, it will approach nearer and nearer to the port 19, so

that by the timeithe exhaust has been ef 1Q?) the charge is firedajand in Fig. 7 the piston and 19 as the case may be, nevertheless that exhaust ports.- It will further be particu-v larly noted that Whereas the ports 18 in the disk at the commencement of the downward and upward movements of the piston 7, are not in full registration with .the ports 19 their registration therewith is such as to exactly coincide with the position and speed of movement of the piston, in other wo,rds,-that -thejdegree of the -opening,'either for the intake or for the exhaust, is co-extensive and contemporaneous Wit the requirements which are determined by. the location and speed of movement of the piston. and in "order that a lead,- as it is called, may be given to theintake or'the exhaust operations, one or both, I suitably change the relative sizeand shape of the ports in the sides- 7 of-the'casing, or suitably change the timing of the disk relative to the ,position of the' crank shaft.

Referring to Figs. 8 to 1 1, it will be noticed that the movement of the'parts and the results secured are the same as above described and that they have been illustrated as applied to a pair of cylinders, that is to say, the heavy black line indicates the disk 15, the two open spaces 18 therein represent two of the ports in the disk and the two right hand openings by the sides of the disk represent the intake openings in the casing and the two left hand openings repre-v sent the exhaust'openings in the casing, in other words, the open1ng36 represents the connection with one of theicylinders, the

opening 37 on the: opposite side of the disk connects with the carbureter, the next pair of openings to the left are 38 connecting with the carbureter, and 39 with the opposite cylinder, the next two openings to the left are 40,'the-exhaust from one of the cylinders, and 41' the connection with the muflier, the next pair of openings to the left are 42 connecting with the opposite cylinder and &3 connecting with the muliier.

The operation is obvious. Fig. 8 coincides with Fig. 4. The openings in the disk are the same as the upper left hand opening in Fig.4 and it will be seen that the right hand opening 18 is just about to come into registration with the passageways 36 and 37 which connect with the carbureter. at one side and one of the cylinders at the other and'likewise, still referring to Fig. 8, that the left hand opening 18 has just passed away from registration with the passageways 40 and 41 which permit the exhaust to pass from the cylinder to the mufiler, as likewise shown in Fig. 4, also that in Fig. 9 the right hand port 18 in the disk is ust about to make registration with the intake ports 38 and 39 which permit the intake of a fresh charge from the cafrbureter to the second cylinder and that theleft hand epening 18 has just passed away pfrom the ports plicable, however,'- to a 4.2 and 43 which rmitted the'exhaust to pass from the second cylinder, so that this Fig. 9 coincides with Fig. 5., I

WVithout 'further elaboratejdescription it will be found that Figs. 10 and 11 similarly colncide with Figs. 6 and 7, being made ap stead of a single one.

"Although I have shown form as preferred. ,Indeed in some constructions of engine, it will be desirable to make them of different form in order "to save space or secure volume of intake or discharge. Therefore the "contour of these- ;.openings or ports is immaterial.

The number and spacing of the eas in the disk and m: the ,casing as being substan-. tially rectangular, theymay be of such other the ports in pair of cylinders inthe disk and in the walls of the casing will ofcourse vary depending upon the number of cylinders co-acting with a single disk and also the speed at :which the disk, is driveln.

These matters will in each case be determined by the designer of the engine No arbitrary rule controls in the matter.

such as preferred. There is no arbitrary size relation that controls. All that is es sential is that the dimensions shall be such as will produce the stated result, that is to The relative dimensionsof-the parts may also be.

say, such as will admit ofthe preferred or suitable opening of an exhaust port during the appropriate upward movement of the piston after an explosion and the like 'closing of the exhaust and opening ofthe intake during the next downward or intake movement of the piston, and the closing of both the exhaust and the intake ports during sub stantially the-whole .of the second or compression upward movement 'of the piston continuing during the second downward or .power stroke of the piston.

It will be obvious to those who are fami1-.

iar with this art that modifications may be made in the details, of construction and. yet theessentials of the invention be embodied.
