ROTARY COMBUSTION-ENGIN FOR AERIAL MACHIN ES.

Specification of Letters Patent.

Application filed August 9, 1912. Serial No. 714,246.

To all whom it may concern:

Be it known that I, Louis VALLEZ, engineer, residing at Lille, Rue du Palais Ribour, Nord, France, have invented a new and useful Rotary Combustion-Engine for Aerial Machines, which is fully set forth in the following specification.

This invention relates to combustion engines and it has special reference to such engines as are revolving about a fixed shaft.

'The object of the invention is to provide an engine of the rotary type that shall be lighter and more compact in construction and specially adapted for use in connection with aerial machines by doing away with the crank shaft and by so arranging the cylinders parallel with their axis that the centrifugal force shall be reduced by reducing to its minimum the diameter of the revolving masses.

In the annexed drawings: Figure 1 -is a general view half in longitudinal section and half in outside view of the engine. Fig. 2 is an end view thereof.

This engine is an engine working on the are performed during a rotation of the cylinders about the fix'ed shaft 2 which is held stationary only in the bearing 21, shown at the right of Fig. 1. With this object in view a drum 3 is fixed on the 1101- low stationary shaft 2 and has a groove 4 cut so as to describe two uninterrupted curves. Within such groove runs a roller 5 provided on a carriage 6 rigidly connected with the two pistons 7 and 8. It will thus be easily understood that when the cylinders 1 are rotated about the fixed shaft 2 the roller 5 running in the groove will reciprocate both pistons. Now, as the curve of the groove is a double one, the four strokes of the pistons required for completing the cycle will be performed during a single rotation of the cylinders about their shaft.

, In order to reduce friction and to prevent deformation of the carriage 6 by the action of centrifugal force, the latter is provided with rollers 10 running on the inner periphery of the drum casing 9 which is closed on each side by the hollow shafts carrying plates 11 and 12 on which are" fixed the cylinders which are provided at their outer ends with the distributing devices.

The mixture is conducted to the inlet valves through the hollow shaft 2 and through channels 13. The plates 11 and 12 carrying the cylinders are both loosely mounted on the stationary shaft 2 on which they freely rotate. The power is transmitted through the prolongation of the plate 12, which for that purpose is extended through the bearing 21.

The inlet valves 17 and outlet valves 18 are controlledby an oscillating lever 16 the one end of which is connected to a pusher 20 which receives its motion from a cam 19 fixed on the side of the drum 3, that is at a place where it is well oiled. There is only one cam for each group of cylinders.

The outlet ducts open into a circular collecting channel rotating with the cylinders for the purpose of damping all noise resulting from the escape and acting as a centrifugal aspirator for producing a partial vacuum in the cylinders during the time of escape whereby the volume of the working mixture drawn in is increased, the piston having no resistance to overcome and being on the contrary attracted toward the bottom ofthe cylinder, thus reducing to a minimum the quantity of burnt gases remaining in the explosion chambers.

Having thus described and ascertained the nature of my invention and in what manner it is to be performed, what I claim is:

1. In an engine of the character described, the combination of a fixed shaft, oppositely disposed cylinders rotatable about said shaft, pistons for said cylinders, means mounted between said cylinders for operating said pistons, a casing surrounding said means, and members closing the ends of said casing and carrying means for transmitting power to a given source.

2. In an engine of the character described, the combination of a fixed shaft, cylinders rotatable about said shaft, piston for said cylinders, means including a drum for operating said pistons, inlet and exhaust valves for said cylinders, and means carried by said drum for operating said valves.

3. In an engine of the character described, the combination of a fixed shaft, a plurality f cylinders rotatable about said shaft, pistons in said. cylinders, piston rods for said pistons, a drum casing, rollers carried by said piston rods and engaging the inner surface of said casing, a drum inclosed by said casing, connections between said drum and pistonrods whereby said cylinders are ro- Patented May 19, 1914.

tated and said pistons reciprocated, inlet and exhaust valves for said c linders, and means carried by said drum for operating said valves.

4. In an engine of the character described, the combination of a fixed shaft, a plurality sf oppositely disposed cylinders rotatable about said shaft, pistons in said cylinders, piston rods connecting the pistons of opposite cylinders, a drum casing, rollers carried by said piston rods andengaging the inner surface of said drum casing, a drum inclosed by said drum casing, connections between said piston rods and said drum whereby said cylinders are rotated and said pistons reciprocated, inlet and exhaust valves for said cylinders, and cams carried by said drum for operating said valves.

5. In an engine of the character described, the combination of a fixed shaft, a plurality of oppositely disposed cylinders rotatable about said shaft, istons for said cylinders, means fixed to said shaft for rotating said cylinders and reciprocating said pistons, a casing surrounding said means and mounted between said oppositely disposed cylinders,

and plates for closing the ends of said cas-- ing, said plates having openings for receiving the 1nner ends of said cylinders.

(3. In an engine of the character described,

the combination of a fixed shaft, a plurality of oppositely disposed cylinders rotatable about said shaft, pistons for said cylinders, means for rotating said cylinders and reciprocating said pistons, a casing surrounding said means and mounted between said oppositely disposed cylinders, and rotatable plates closing the ends of said casing, said plates having openings receiving the inner ends of said cylinders.

7 In an engine of the character described,

the combination of a fixed shaft, a plurality of cylinders rotatable about said shaft, pistons for said cylinders, means for rotating said cylinders and reciprocating said pistons, a casing surrounding said means, and rotatable members closing the ends of said casing and having sleeves extending from said members and surrounding said shaft for transmitting power to a given source.

8. In an engine of the character described,

the combination of a fixed shaft, bearings for said shaft, a plurality of c linders rotatable about said shaft, pistons or said cylinders, means fixed to said shaft for rotating said cylinders and reciprocating said pistons, a casing surroundin said means, and plates closing the ends 0 said casing and having sleeves extending from said plates and surrounding said shaft, one of said sleeves being journaled in one of said bearings and adapted to transmit power to a given source. 7 9. In an engine of the character described, the combination of a fixed shaft, bearings for said shaft, a plurality of cylinders rotatable about said shaft, pistons for said cylinders, means fixed to said shaft for rotating said cylinders and reciprocating said pistons, a case surrounding said means, and plates closing the ends of said casing, one of said plates having a sleeve extending therefrom and surrounding said shaft, said sleeve being journaled in one of said bearings and adapted to transmit power to a given source. In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
