INTERNAL-COMBUSTION ENGINE.
Specification of Letters Patent.
Patented Sept. 12, 1916.
Application filed September 30, 1915. Serial No. 53,438.
The invention comprises various features of construction as hereinafter set forth.
In the drawings: Flgure 1 1s a central longitudinal section through the engine; and
Fig. 2 is a cross section thereof.
A is a casing having opposite alined cylindrical portions B and C connected by an intermediate portion D.
E is a hollow piston bridging the intermediate portion D and engaging and reciprocating in the opposite cylinders 13 and O.
F is a rotary cam Within the piston E, which is mounted upon a shaft G extending outward through one end of said piston and cylinder and providing suflicient clearance for the free reciprocation of the piston.
To convert the reciprocatory movement of the piston into rotary movement of the cam F, the latter is provided with a cycloidal endless groove H which is engaged at diametrically opposite points by roller bearings I and I mounted on the piston. The piston is also provided with external roller bearings .l which engage longitudinal grooved guides K formed in the intermediate portion D of the casing, the arrangement being such that the piston is compelled to travel in a rectilinear path by the guides K, while the engagement of the rollers I with the groove H will communicate a rotary movement to the cam F.
The rolls I and J are preferably connected to a common pivot member L which passes through a removable bearing M engaging a threaded aperture in the walls of the piston E. The piston is provided with rings N or other means of forming a tight connection with the cylinders B and C, and a ring or packing O engaging a sleeve bearing P in which the shaft G is journaled. Endwise movement of the shaft G and cam member F is prevented by suitable thrust ized as a two-cycle gas engine.
bearings, and as shown one of these is formed by the cam and the other by a collar Q on the shaft G.
lVith the construction as thus far described, it is evident that the alternate introduction and exhaustion of a suitable motive fluid in the cylinders B and C will impart reciprocating IHOVQHIGlli) to the piston, which through the mechanism described will convert this movement into rotary movement of the cam F and shaft G. Preferably the motive power is developed by internal combustion, and as shown the engine is organ- The explosive charge is introduced through an inlet valve B- into the cylinder C during the outward stroke of the piston and is compressed upon the return stroke, until a transfer port S leading from the cylinder C to the cylinder B is opened by the movement of the piston in the latter cylinder. This will admit the compressed gaseous charge to the cylinder B, where it will expel the products of a previous explosion through an exhaust port T, as is usual in two-cycle engines. The cylinder B is preferably water-jacketed as indicated at U, and
a spark-plug V is provided for ignition.
In order to equalize the volumes of the two cylindersB and C and to expose equal piston areas therein the cylinder C is of slightly greater diameter than the cylinder 13, so as to compensate for the cross section of the shaft G and sleeve bearing P.
What I claim as my invention is 1. In an engine, the combination with a casing having aXially-alined opposed cylindrical portions and an intermediate portion of greater diameter than said cylindrical portions having longitudinally-extending guides, of a hollow piston bridging said intermediate portion and reciprocating in said cylindrical portions, a rotary cam within said hollow piston, ashaft on which said cam is mounted extending out through one end of said piston and cylinder, thrust bearings for holding said shaft from endwise movement, and means mounted on said piston cooperating with said rotary cam and said longitudinal guides for converting the reciprocatory motion of the piston into r0- tary motion of the cam.
2. In an engine, the combination with a casing having axially-alined opposed cylinder portions and an intermediate connecting portion providing longitudinal guides,
of a hollow piston bridging said intermediate portion and reciprocatingly engaging saidcylinder portions, a rotary cam within said hollow cylinder, a shaft on which said cam is mounted passing outward axially of said piston and cylinder, a thrust bearing for preventing endwise movement of said cam and shaft, and diametrically opposed members upon said hollow piston extending inward and outward therefrom respectively engaging said cam and said longitudinal guides to convert the reciprocatory motion of the piston into rotary movement of the cam.
3. An engine, comprising a casing having opposed axially-alined cylinder portions and an intermediate portion providing Ion-- gitudinally-extending guides,a hollow pie-- ton bridging said intermediate portion and reciprocatingly engaging said cylinder por tions, a rotary cam within said hollow cylinder, a shaft on which said rotary cam is mounted passing axially out through said piston and cylinder, means for preventing endwise movement of said cam, bearings onv said piston member respectively engaging said rotary cam and longitudinal guides, and means for introducing a gaseous charge in one of said cylinders and for transferring said charge, compressing and exploding the same in the opposite cylinder. l 4. An engine, comprising a casing having aXially-alined opposed cylinder portions and an intermediate connecting portion providing longitudinally-extending guides, a hollow piston bridging said intermediate portion and reciprocatingly engaging said cylinder portions, said intermediate portion being spaced from said piston, a rotary cam within said hollow piston, a shaft on which said'camis mounted passing axially out through said piston and cylinder, means mounted on said piston cooperating with said guides and cam forconverting the re ciprocatory movement of said piste into rotary movement of said cam and shaft, and means for utilizing said opposite cylinder portions for the compression and explosion of a gaseous charge to reciprocate said piston.
In testimony whereof I affix my signature in presence of two witnesses.
