lle it known that ll, Anienrsr W. Bienen, a citizen 'ot the rUnited States, residing at llloomiield, in the county-ot avis, State ot lovva, have invented a nevv and useful lltotary Explosive-Engine; and l do hereby declare the following to he a lull, clear, and enact description ot the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved rotary internal combustion engine, and an ohject ot' the invention is to provide an engine of this kind having simple, improved and practical features or" construction.

@ne ot the features ot construction is the n provision oiga casing having' intake ports, exhaust ports, and a hollovv cylinder valve rotatahle in the casing and provided with a port to alternately register with the iirst ports, tor intaking and exhausting the interior ot the cylinder valve constituting the conihustion chamber, in which the piston is reciprocated.

Another feature of the invention is to provide a multiple cylinder internal combustion engine, in Which improved connections are provided hetvveen the crank shaft and the coinhined revoluble cylinder valve and comhustion chamher casing so that when the ports ot said valve alternately register with the intake and exhaust ports of the casing, the piston will in turnA receive its charge, and exhaust the utilized gases.

In practical iields'the details of construction may necessitate' alterations, .falling1 Within the scope ofwhat is claimed.

The invention comprises further features and combination of parte, as hereinafter set forth, shown inthe drawingsand claimed.

Mounted in hearings ot the crank casingsl and 2 is a crank shaft o, to which; the sprocket 'i' is hired hy means ot the key or feather 8 that is, hetvveen the-two crank casings, and upon one end of the crank shaft 6 the drive pulley 9 is mounted. The shaft 6 is provided with the cranks l0 and l1, to which the pitinan rods 12 and 13 are connected by means oi the cap plates lt and bolts 15.l The upper end of each pitman terminates in the usual hearing sleeve positionl of the cylinder the en* et the 16.' The bearing sleeves .16 arev pivotally mounted upon the pins 17 on the interior of the pistons 18 and 19. The cylinder casings are provided'vvith the usual cylinder heads 20, which are secured to the upper ends of they cylinder casings by means of the bolts 2l. The cylinder heads 20 and the cylinder casings are provided with the usual Water the usual sockets 23 for the spark plugs 24.- and 25. its shown in Fi s. 2 to 5 inclusive it will he seen that the cylinder casing's are provided vvith intake and exhaust ports 26 and 27, and revolubly mounted in said cylinder casings are cylinder valves 28 and 29,- which are suhof the same length as the cylder casings, and are htted telescopically in said casing, but for revoluhle movements comparatively loose therein, and these cylinder valves are provided vvith diametrically oppositely disposed ports 31 and 32, rotates through jackets 22, and

' upon the shaft their connections with the crank shaft, said ports 31 and 32 alternately register with the intake and exhaustl ports 26v and 2'?. 1n other words, when the port 31 registers with the exhaust port 27,'the utilized gases are exhausted; therefore the port 31 at this in# stance will constitute an exhaust port. FThen the ,port 31 will register with the intake port 26, thereby perm1tting an intake charge, and in this case the port 31 will actas an intake port. rlhe same is true in regard to the port 32 as it registers with lirst the exhaust port 27 and thenv the intake port 26. rlhe usual intake and exhaust manifold 33 and 34 are connected to the intake and exhaust ports 26 and 27, as seen in Fig., 1. Mounted in bearings ot the upper art of the crank casings is a shaft 35, to w ich, a sprocket wheel 36 is fixed by means of the pin 37. The collars 38 which are secured 35 by the pins l39 prevent endwise or axial movement of the shalt 35. The sprocket 36 has a sprocket chain connection 40 with the sprocket wheel 7 of the crank shaft. Rotatable with the shaft 35 are worms t1 and 42, which mesh with the worm teeth 43 of the iianges it ot the lower parts of the cylinder valves 28 and 29. 1t is. to be seen that by virtue ot these connections that the cylinder valves 28 and 29 will rotate, in order to correspond with the intake of a charge, the compression thereof, the hring ot the same, and finally the exhaust of the utilized gases. Mounted in the wall of each cylinder casing is a stub pin 46, secured in position by the nuts 47, and on the inner end of the stub pin a roller 48 is mounted for engaging the under surtace of the tlange fit of each cylinder valve tc support the same in position as it rotates. and 10 additional intake and exhaust ports t9 and 50 are provided, in which case the intervals between the explosions must neces-y sarily be decreased; hence the gearing between the cylinder valves 23 and 29 must necessarily be changed accordingly, but which altered connections are not shown.

it will be seen that the stub-pin e3 previously-referred to has its two ends otlset with respect to each other, giving it the shape ot a crank. By the roller 18 being on this cranked end, the stub-pin 4:7 can be loosened in. the casing and the roller i3 adjusted to compensate tor any longitudinal wear that may have occurred in the cylindrical valve.

'ln so far as the operation ci this engine concerned, it is only necessary to 'forth the operation ci one cylinder, it is to he nnderstood that the pistcns oi both cj ders alternate in their cycles ot operations. Referring to the piston 13, it is to be seen that as said piston starts on its downward Athe intake port 26.

vcompressing the charge.

stroke, the charge is fired, as a resu nl rigs. 7, e, 9-

intake for a certain stroke, one or the other of the ports 31 and 32 is beginning toregister with the intake port 26,`thereby sucking in a charge. After the piston 18 reaches the end of its down intake stroke, either one of the ports 31 and 32 has passed out of registration with The piston 18 then starts on its upward compression stroke,

Immediately following the completion of the compresiori t o which the piston moves downwardly. The piston, after completing the liring stroke, starts upon its upward stroke, just about, or substantially `a littleafter one or the other of the ports 31 and 32 begins to register with the exhaust port 27, thereby exhausting the utilized gases. Therefore, substantially at the time Vthe piston completes its exhaust stroke and instantly subsequently starting on its next intake stroke, one or the other ot the'ports 31 and 32 is beginning to register with the intake port 26. llt is to be noted that the gearing between the crank shaft 6 and the cylinder valve is of such design and construction as to operate the cylinder valve so that said ports will register approximately at the time as above set orth, it to be understood that the pistons of both cylinders carry out the foregoing cycles of operation alternately. 'in an engine involving the construction and arrangement of intake and .exhaust ports such as shown in Figs. 7 to 10iinclusive, it is to be understood that the gearing between the crank shaft 6 and the cylinder valve should be so designed and vconstructed as to rotate the cylinder valves of both cylinders at 'Easter rates of speed than the cylinder valves shown in Fig. 1, owing to there being just double of intake and exhaust ports to those shown in Figs. 2, 3 and @l and 5. rllhe gearing for providing this increase of speed can consist of the same parts as disclosed in Figs. 1 and 6, with the exception that the teeth and threads of the worm wheels and the worms may be constructed on a greater pitch.

The invention having been set forth, what is claimed as new and useful is:
