SPECIFICATION forming part of Letters Patent No. 767,549, dated August 16, 1904.
Application filed February 13, 1904. Serial No. 193,395. (No model.)
- T0 (LZZ whom it may concern.-
Be it known thatI, ADAM S. DICKISON, a citizen of the United States, residing at Woodbury, in the county of Gloucester and State of New Jersey, have invented certain new and useful Improvements in GasEngines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled-in the art to which it appertains to make, and use the same.
This invention relates to gas-engines and other similar motors; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.
In the drawings, Figure 1 is a vertical section through a gas-engine constructed according to this, invention. Fig. 2 is a side view of the engine, showing the base in section.
A is the base, and B represents stationary guides secured to the said base. C is the cylinder, which is slidable in the said guides.
D is the crank-shaft, which is journaled in suitable bearings d, secured to the base, and (Z is a fly-wheel secured on the said crank-shaft.
The crank-shaft D is provided with two cranks 7) and c, which are arranged opposite to each other, and a third crank b is also provided in line with the crank b, so that the cranks b b are duplicates.
E represents connecting-rods. which engage with the cranks Z) Z) and which are pivoted to pins 0, projecting from the cylinder C, so that the said cylinder is reciprocated in the guides B when the crank-shaft is revolved.
F is a-piston which is slidable in the cylinder 0, and f is a connecting-rod which is pivoted to the piston by a pin f and which engages with the crank 0. The inner end of the cylinder is open, and its outer end is closed by a cover G. The admission-pipe g for gas and air is secured to the said cover, and g is the admission-valve, which is operated automatically or in any other approved manner.
H is the exhaust-valve, which is also carried by the cover G, and h is the exhaustpipe. These valves are preferably arranged as shown upon the cover; but they may be arranged in any other approved manner at the working. end of the cylinder.
the said cam-shaft.
I is a revoluble cam for operating the exhaust-valve. This cam is secured on a camshaft-c, which is journaled in suitable bearings i, and J is a toothed wheel secured on A toothed pinion j of one-half the diameter of the wheel J is journaled on a pin 1', which projects from the side of the cylinder C, and la is a crank-pin for re- Volving the said pinion. This crank-pin is connected with the pinion in any approved manner, and it is preferably secured to a crankplate K, which is secured to the said pinion.
M is an eccentric which is secured upon the crank 6, and m is an eccentric-rod operated by the said eccentric. The eccentric-rod on has a longitudinally-slidable portion or extension m, which is pivoted to the crank-pin k.
N is a spring arranged between the eccentric-rodm and its extension m. The toothed pinion j gears into the toothed wheel J, so
that the cam-shaft is revolved once during two revolutions of the crank-shaft.
The piston and the cylinder move simultaneously in opposite directions. A charge of gas and air or other inflammable fluid is drawn into the cylinder during one outstroke of its piston. This charge is compressed during the next instroke of the piston. The compressed charge is ignited by any approved igniting mechanism during or at the commence ment of the second outstroke of the piston,
and the products of combustion are expelled from the cylinder during the second instroke of the piston. The exhaust-valve is held open by its cam during the second instroke of the piston, and at other times it remains.
the said cylinder; of a valve carried by the said cylinder, a toothed wheel and a toothed pinion gearing together and also carried by the said cylinder, driving devices between the said wheel and the said valve, an eccentric secured on the said crank, and driving connections between the said eccentric and the said pinion, the said valve being operated once during each two revolutions of the said crank-shaft.
2-. The combination, with a guide, and a crank-shaft provided with a crank; of a powercylinder slidable in the said guide, a rod operatively connecting the said cylinder with the said crank, an GXlliLLlSh-VZLlVG carried by the said cylinder, a cam for operating the said valve, a toothed wheel revolving with the said cam, a toothed pinion supported by the said cylinder and gearing into the said wheel and provided with a crank-pin, an eccentric carried by the said crank, and an eccentric-rod operatively connecting the said eccentric with the said crank-pin.
3. The combination, with a slidable powercylinder, and a crank which operates it; of an exhaust-valve carried by the said cylinder, a cam for operating the said valve, a toothed wheel revolving with the saidcam, a toothed pinion supported by the said cylinder and gearing into the said wheel and provided with a crank-pin, an eccentric carried by the said crank, an eccentric-rod secured to the said eccentric and provided with a slidable extension which is connected to the said crank-pin, and a spring connecting the said. eccentric-rod and its extension.
In testimony whereof I have affixed my sig* nature in the presence of two witnesses.
ADAM S. DICKISON.
