Description: |
| Application renewed 16 Dec 1889.
Abstract:
One portion of my invention is applicable to and of value in any engine of this general type in which fuel is burned at only one side of the piston, provided that the opposite end of the cylinder be so closed that a partial vacuum may be induced therein on the side of the piston opposite to that at which the firing occurs, and also provided that said fuel be burned at strokes of the piston which intervene with strokes during which no burning occurs, and still further provided that atmospheric pressure can be permitted to act upon the firing side of the piston during those strokes thereof which alternate with 35 the firing strokes.
Claim:
The combination, substantially as hereinbefore described, of a cylinder closed at both ends, a piston, appliances for supplying to fuel to said cylinder and igniting it at one side of said piston, a condenser communicating with both ends of the cylinder, a valved air-inlet for supplying air to the firing end of said cylinder, a valved exhaust-port at said t5 firing end of the cylinder and between the latter and said condenser, positively-actuated valve mechanism by which said air-inlet port is opened during portions of the alternating non-firing forward strokes of the piston, and also for intermittingly opening said exhaust- port, and an auxiliary exhaust-port, which is located at the opposite or non-firing end of the cylinder guarded by a valve so weighted as to freely open to pressure within the condenser and within the communicating non-firing end of the cylinder. |
