all whom it may concern:

Be it known that 1, CHARLES STIRIZ, a citizen of the United States, and a resident of the cityof New York, borough of Manhattan, in the county and State of-New York, have invented a new and Improved Internal-Combustion Engine, of which the following is afull, clear, and exact description.

My invention relates to internal combustion engines, my more particular purpose being to provide such devices with an improved water jacket in which the water is caused to circulate by the conjoint action of centrifugal force and difference in density between hot and cold water.

My invention also contemplates an engine made up of a plurality of units so arranged that when an explosion takes. place in one'unit, the gases of combustion are con ducted to another unit, and there mixed withsteam, this mixture then expanding and doing work within the second unit.

My invention further eomprehends y'arious details of construction whereby the efiicienoy of the engine is greatly improved.

ing a general annular form and secured in position by aid of screw bolts 16.

A hydro-carbon supply pipe is shown at 17 and is provided with a nozzle 17 Mounted rigidly. upon 'thisnozzle is a ring 18 and engaging the latter is a worm 19. This worm is connected to a. hand wheel 20 andis journaled within a bracket 21. The nozzle 17 extends through the disk 12. Secured upon the disk 12 is a tube 22 provided Withan air hole 23. The nozzle 17 extends into this tube 22 and is coaxial therewith. A valve having generally a cylindrical-form is provided with holes 24 and is revolubly mounted within the tube 22. connected With the tube 22 and is disposed adjacent to the valve 25. This valve is adapted to turn step by'step and in so doing brings the holes 24- successively into registry with the tube 26. The valve 25 is provided with a stem 27 and mounted firmly upon this stem is a so-called Geneva cross 29. A cam wheel is disposed adjacent to this cross and is provided with lugs 28 arranged as shown in Fig. 1, and adapted to successively turn the cross 29 and thus actuate the valve 25 step by step. The valve 25 and parts immediately associated therewith together constitute a carbureter.

The pipe 26, at its outer end, is connected with a wall 31 having the shape indicated in Fig. 1. This wall is integral with a ring 32 which is supported upon spokes 32 and is provided with an inclined portion 33, the latter being integral with the wall 31, these two parts together forming an abutment which receives the force of the exploding gases. This abutment is provided with my newly invented packing 34. A revoluble casing 35 is provided with an inner wall 35 and an outer wall 35' and With a passage 36 disposed between these walls. A pipe 37 communicates with this'passage and also communicates with an annular passage 38 located within a hub 38 with which the casing 35 is provided. Another pipe 39 communicates with the passage 36 and with an annular passage 40, the latter being located within thehub 38. The revoluble casing 85 is partly supported upon a number. of rolling bodies 41 arranged in a circle around the disks .7, 12, and constituting a ball bearing. The-casing 35 is providedwith two compartments 42, as will be understood ,from Fig. 1. #In each of these compartments 15.11

A pipe 26 isa contact 44.

spark plug 43, and adjacent to the latter is This contact is connected with a binding post 41 and is adapted to be closed and opened as the casing turns. Two gates 45 are carried by the casing and located within the compartments 42. Each gate 4-5 is mounted upon a-rockingshaft 46, and connected rigidly with the latter is an arm 47 carrying a roller 48. This roller runs upon the cam frame 14, the latter being provided with a cam 49 extending outwardly, as will be understood from Figs. 1 and 2.

A pipe 50 extends through the ring 32 and across the machine, bein connected with an abutment 51 carried a casing 51. This abutmentis practically an extension of a ring 52. The revoluble casing 51 is provided with two gates 53 disposed diametrically opposite each other and located in compartments 54. Each of these gates is free to swing and is provided with an arm 55 carrying a roller 56 which runs upon the cam frame 15. This frame is provided with a cam 15 which periodically guides the rollers 56 outwardly and in so doing turns the gate 53.

A cam wheel 57 turns with the casing 51- and-engages a cross 58 similar to the cross 29 and turns the latter step by step. Connected with the cross 58 is a rotary valve 59 which is mounted within a valye casing 60 and connected with a steam pipe 61."v This steam pipe taps into the tubular hub ll and, as the casing 51 turns, is periodically brought into engagement with each hole 9.

. The pipe (ii-terminates in a nozzle 62 which extends into the compartment '54. Apipe 63 is connected with the compartment 54: and serves to d scharge the gases of combustion as they finally emerge from the machine'. A power wheel 64 is connected rigidly with the tubular shaft 4, and is turned thereby for the purpose of transmitting through the opening 23. the explosive mixture is forced through the pipe 26' and into the explosion chamber. Each time the casing 35 makes a turn. each door 45 is opened and closed by the action. of its roller 48 upon the adjacent cam frame 14.- and cam 49. The

gate 45 is always closed, as indicated in Fig.

1, when the explosion takes place; Each gate 45, upon a proaehing the lnclined'portion 38 of the ring 32, rides outwardly upon this portion and, upon traveling around a little farther, is free to close which it does under the guidance of the cam roller associated with it.

The gases of combustion pass'through the pipe 50 across the machine and are admitted intothe compartment 54, so as to heatup their surroundings and exert a constant pressure. Here they unite with steam from the nozzle 62, this steam being discharged periodically and at the right moment to come into con tact with the exhaust gases just mentioned.

The mixture of the exhaust gases and the steam causes rapid'expansion, and this assists in driving the revoluble casing 51. When the gasesfinally escape through the pipe 63 they have completed their work.

Water being admitted through the pipe'5 has free circulation through the pipe 37 out into the compartment 36 of the casing 35 and back through the. pipe 39 to the tube 4 from whence it makes its escape. As the water, while in the compartment 36, is heated by the explosions, thediiference in the specific gravity of the water thus heated and the cold water as it enters is suflicient, in connection with the action of centrifu al force, to cause the water to circulate freely; that is to say, the mere heating of the wa ter, by slightly lessening its specific gravity, causes the machine in acting under centrifugal force to act with greater intensity upon the cold water when it enters than upon -the hot water already in the machine,.so that the net result is a tendenc' upon the .part of the machine, to induct the cold water and throw it to the outside, the hot water in the meanwhile constantlymaking its escape.

This tends to keep the coldest portions of the water out near the edge of the revoluble casing where the greatest heat would otherwise be developed. It also renders the circulation of the Water completely automatic in the sense that no pump or similar device is necessary in order to effect a good circulation. Each time the cam wheel 30 causes the cross 29 to turn a. quarter of a revolution, the carbureter is actuated accordingly, being either opened or closed, as the case may be, so that the carbureter is closed whenever the engine is in condition for an explosion to take place. Similarly, whenever the cam wheel 57 causes the cross 58 to turn the valve 59, this valve always stops 'in such position that an explosion within the explosion chamber 54 cannot force anygases of combustion through the pipe 61.

I do not limit myself to the particular construction here shown and described, as variations may be made therein without departing from the spirit of my invention, the scope of which is commensurate with my claims. Neither do limit myself in every instance to the use of explosions, as in some.

relations various other modes of propulsion may be employed, all coming within the I claim as new and desire to secure by Letters Patent is 2-- 1.
