GAS-ENGINE.
SPECIFICATION formingpart of Letters Patent No. 658,858., dated October 2, 1900.
Application filed Janua'ryZ, 1897. Serial No. 620,674. (No model.)
To (LZZ whom t may concern.'
Beit known that l, LEWIS HALLocK NASH, a citizen of the United States, and a resident of South Norwalk, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Gas- Engines, of which the following is a specication. I
My present invention relates to valves for 1o gas-engines; and it consists ot' certain novel parts and combinations of parts particularly pointed out in the claim concluding this specification.
In the accompanying drawing I have shown i5 my invention embodied in the form which is at present preferred by me; but it will be ununderstood that various modifications and changes may be made without departing from the spirit of my invention and without eX- ceeding the scope of the concluding claim.
The accompanying drawing shows a vertical section through the inlet and outlet ports of a gas-engine, the valves controlling said ports being shown in elevation.
Referring to the drawing, A is the cylinder of a gas-engine.
B is the inlet-port for admitting gasesto the combustion-cylinder, and C the outletport for exhausting the waste gases therefrom.
B' is a passage leading'to the air.
D is the inlet-valve, and E the outlet-Valve.
The two ports B and C and their passages B and C are contained in a single casting, which casting is provided with comparatively- 3 5 long bearings E' and D for the valve-stems D5a and E2.
F F are spiral springs abutting at their upper-ends against the opposite casting and at their lower ends against adjustable sleeves G G, attached tothe valve-stems.
H is a bearing for the valve-stems, placed below the springs F F.
.I J are adjustable nuts for taking up lost motion in the valve-stems.
ports M M and carrying rollers K K, which rocking arms are controlled by cams N N. These cams are attached to a shaft O, to which a gear-wheel P is attached, meshing with a pinion Q, attached to the main shaft R of the 5o engine. It will be observed that the countershaft O in this construction `stands directly above the main shaft R of the engine and that the rocking arms L L overlap, being fulcrumed on opposite sides. By these means 55 the elements are brought together in a small space, so that they may be contained more readily, if desired, in a suitable frame of moderate dimensions without impairing the efficiency of the device.
The ports, passages, and the guides for the valve-stems are all made in a single integral casting, which is also provided with waterpassages S S S, forming a water-jacket. It will also be observed that the spiral spring E, which controls the action of a valve, is located between two bearings E and H or D' and H. The effect of this arrangement of parts is to relieve the Valve-stem of friction and wear. The presence of such a spiral 7o spring or analogous mechanism for reasons which are well understood gives rise, as these parts are ordinarily made, to side strains, which are exceedingly injurious. By placing the spring between two bearings these side strains are overcome and their ill effects entirely neutralized.
What I claim is- In a gas-engine a plurality of puppet-valves having parallel stems, rocking arms respec- 8o tively pivoted to said stems at one end and to fixed bearings at the other, said rocking arms overlapping one another, and cams by ,means of which the said rocking arms and valve-stems are operated.
