EXPLOSIVE-ENGINE.

Specification f Letters Patent Patented Mar. 10, 1914. Application filed May 4, 1912.

Serial No. 695,200.

To all 'whom t may concern Be i-t known that l, JAMES M. MORGAN, a citizen ofthe United States, residing at Royal, in the county of Clay and State of Iowa, have invented a new and useful Explosive-Engine, of which the following is a specification.

The present invention relates to improve- :ments in explosive engines, the primary object of the invention being the provision of a novel form of rotary valve, whereby the intake and exhaust ports of an explosive motor are properly controlled to permit of the introduction of an explosive charge to f and the exhaust of the burnt gases from the upper end ot' the explosive chamber of the engine. n

A further object of the present invention is the provision of a novel form of casingl disposed adjacent to the intake and exhaust ports of an explosive engine and to which `are led conduits from the respective intake and exhaust manifolds, with a rotary disk valve interposed to control the admission of r the explosive charge and the exhaust of the burnt. gases from the engine, this arrangement providing a four cycle engine without the employment of the usual puppet valves and springs.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure l is a side elevation of a four cylinder explosive engine, one of the cylinders heilig shown in section to properly show the positioning of the rotary valve, while the other cylinders show the casings for containing and the shaft for operating the .rotary valves. Fig. 2 is a top plan view of the engine, Fig. is a section taken on line 3 3 of Fig. 1 Fig. et is a section taken on the same line looking in the opposite direction. Fig. 5 is a perspective view of the shaft with the rot-ary disk valves attached thereto.

.which as engine, 2 the intake manifold and 3 the exhaust manifold. Leading from the intake manifold 2 is a conduit 4i, there being one to each cylinder. Each conduit et is also connected to its respective casing 5in communication with its intake channel 4 which terminates in line with the intake port a of the cylinder. Registering with the exhaust port of the cylinder is a channel 6 which has disposed in communication therewith, the exhaust conduit 7 which is connected to and 1n communication with the exhaust manifold 3.

The semi-circular casing 9 is connected to the head of the cylinder l and also to the upper portion of the casing 5, said casing 9 providing a hood for the rotary disk valve 18, shown is keyed upon the shaft 10, said shaft 10, as clearly shown in Figs. 1 and 2, having keyed thereupon at one end the sprocket 11. In order to operate the shaft 10 and the various rotary valves keyed thereupon, in proper time with the crank shaft of the engine, a sprocket chain 19. connects the sprocket 11 to the sprocket 13 mounted upon the counter-shaft 14, said counter-shaft 14 receiving its motion through the sprocket chain 15 and sprocket 16 by means of the crank shaft 17.

As before stated, the rotary valves 18 are all of disk shape and each is provided with ports 19, so positioned as to be placed in registration at the proper time with the respective intake and exhaust ports a and of the cylinder 1, and thus at the proper time admit the explosive charge to the explosive chambcr of its individual cylinder, and permit of the exhaust or escape of the burnt charges at the proper time. These ports 19 of the respective valves 1S are positioned as shown in Fig. 5, so that the respectivo pistons (not shown) of the various cylinders 1 will be actuated to properly operate the crank shaftl 17, said ports 19 being so positioned as to permit of a four cycle action in cach cylinder.

As shown at Q0 in Fig. fl, a lubricant compartment is; provided so that the disk valve 1S will be properly` lubricated during its ro tary action between thc casing 5 and the engine cylinder 1 and Within the hood 9. It is evident that the disk valves may have suitable packings in the adjacent Walls of the cylinder or casting 9. v

The oil to the recess 20 is supplied in any desired manner, but preferably from the crank case by a force or splash feed system.

From the foregoing description, taken in connection with the drawings it will be noted that the respective valves 18 are disposed to operate transversely of the motor and by reason of the shaft 10 being disposed centrally above and longitudinally of the cylinders, all of said valves may be readily alined and be actuated With the least amountv of friction, thus dispensing with the employment ofsprings and producing at all times the ing the compression and explosion strokes of the pistons. Furthermore by disposing the valves and constructing them as shown, there is less liability of the collection of carbon to interfere with the actuation of the valve as is the trouble with puppet valves and as each valve is provided with its individual at 20, the surfaces of each valve are properly lubricated to reduce the friction and at the same time the eX- pansion of the metal of the valve durlng the operation of the engine.

By mounting the rotary disk valves as herein set forth, a silent motor is produced, by eliminating the usual cam shaft, puppet valvesand springs, andit is also evidentthat the engine may be run at an exceedingly high speed with practically no relative loss of power, and as the rotary valves are pro- .vided each with a single port, the time of intake and exhaust will be in proportion to that of the speed, the engine at all times having the same torque at all speeds. Further 'by having the valves lpositioned as shovvn,.the same are never over-heated to produce a binding action as the greater portion of the valve is above the heated portion of the cylinder at all times.

What is claimed is: y

1. An explosive engine, having a plurality of cylinders, each of which is provided with an intake and an exhaust port in one side and near the head, a projection carried by each cylinder having channels leading to the respective ports of the cylinder, a plurality of rotary valves, one to each cylinder each valve being provided with a single port and disposed between the ports and channels of its respective cylinder and projection, each of said valves also having a portion thereof normally above the cylinder, a power piston inI each cylinder, a crank shaft voperably connected to all of the pistons, a single shaft disposed longiturlinallyof and above all of the cylinders and carrying all the valves` and means for desired tight valve structure duroperabl connecting said valve shaft'to the crank s aft.

2. An explosive engine, having a plurality of cylinders, each of which is'provided with an intake and an exhaust port in one side near the head thereof, a projection carried by each cylinder having two channels one to each port of'its respective cylinder, a plurality of rotary valves, one to each cylinder each valve being disposed to intersect the channels and ports of its respective cylinder, each of said rotary valves being provided with a single port, a portion of said Valve being disposed vabove and transversely of the cylinder head, a hood connected to the cylinder and projection and incasing the portion of the valve above the head, a power piston mounted in each cylinder, a crank shaft operably connected to all of said poWer pistons, a shaft journaled -above and longitudinally of all cylinders,

and connected to simultaneously operate all of the rotary disk valves, and means for operably connecting said last mentioned shaft to the crank shaft.

valves, one to each receptacle and disposed so that a portion thereof is Within the receptacle, each of said rotary valves being provided With a single port to control the respective ports of the cylinder, and being 'so positioned that a portion thereof is projected above the head of the cylinder, a hood connected to the head of the cylinder and providing a casing for the upper portion of the valve, a power piston mounted in each cylinder, a crank shaft operably connected to all of said pistons, a shaft journaled longitudinally of and above the cylinders, said shaft carrying all ofthe rotary disk valves, and means for operably connecting said valve shaft to the crank shaft.
