GAS-ENGINE.
SPECIFICATION forming part of Letters Patent No. 632,762, dated September 12, 1899.
Application filed June 13, 1898. Serial No. 683,310- (No model.)
To ctZZ whom it may concern.-
Be it known that I, HINSDALE SMITH, a citizen of the United States of America,and a resident of Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Gas- Engines, of which the followingis a full, clear, and exact description.
This invention relates to improvements in gas-engines which are operated by the explosion of gas, vaporized hydrocarbon, or other suitable explosive fluid within the cylinder or cylinders thereof.
The invention relates to improvements in the construction of the valves for the cylinder or cylinders of the engine for the attainment of objects and advantages hereinafter rendered manifest; and the invention consists in the constructions and combinations or arrangement of parts and appliances, all substantially as will hereinafter be described and set forth in the claims.
Figure 1 is a plan view of suflicient of an explosive gas-engine to illustrate the applicability of the novel valve mechanism which is shown in place thereon. Fig. 2 is-a perspective view of a part in detail to be hereinafter particularly referred to.
The cylinder has at its rear end or head the ingress-port Z) and the exhaust-port cl, with respectively-provided valves 5 d alternately closing and opening, the suction force ex- .erted by the piston in its alternate forward strokes causin gthe in gress-valve to then open against its spring 12,while the exhaust-valve may be positively operated by any suit-able mechanism.
0 represents a carbureter located in one side of and below each cylinder or otherwise suitably located. A conduit 1' leads from the carbureter into the inclosing chamber b within which is provided the valve for the ingressport for the cylinder aforesaid. The conduit 6, leading from the carburetor to the ingressvalve appliances for each cylinder, comprises the pipe-section or hollow casting 27, located toward the cylinder, which is angular or formed with the elbow, which constitutes the casing-like portion Z1 the same having its end nearest the cylinder open for substantially its whole diameter, while in the line of the axis of the elbow portion of this casting,
through the back thereof, is the hole 46. The open-ended elbow portion is seated in a rabbeted depression 47 thereforin the annular bushing 48, which screws into an opening therefor in the end of the cylinder, in the inner end of which part 48 is formed the valveseat I), and which part 48 is externally polygonal or otherwise properly constructed, whereby to enable it to be screwed into its place. The said annular valve-seat has integrally cast as one therewith the spider-legs 4:9 and the spider-supported tubular guide z for the stem 53 of the valve b, said stem protruding outwardly beyond the end of theguide 52. The outer end of said valve-stem guide 52 is externally screw-threaded, receiving thereon the nut 54 to be set against the back of the elbow and to hold such portion of the conduit-section 27 firmly to its seat. The outer end portion of the valve-stem is also screwthreaded, receiving thereon the nut 55, between which and the nut 54 the outwardlyreacting spring 12 is provided under suitable compression to normally maintain the valve closed. The spring, however, is comparatively light, so as to be overcome by the suction-pressure as the piston has its suctionstroke between the explosive strokes.
Each exhaust-valve (Z has provided in conjunction therewith duplicates of the parts just described, constituting the valve-seat bushing and extended valve-stein guide, angular pipe-section 27" corresponding to the one 27, nuts, and springs, although it is to be stated that each angular conduit-section 27" is outwardly continued in the exhaust-com veyer, which, if desired, may terminate in the muffler.
The valve devices, which have been illustrated and described quite in detail and of which the inlet and exhaust valves are sub stantially duplicates, are designed to the end of rendering more convenient the assemblage and replacement of the valves proper and their seats than heretofore in gasolene-engines, so far as known to me. The valves after more or less extended use become fouled, clogged up, and worn, failing to properly seat or to remain tight, and it is often.1 n0re expeditious and desirable to substitute new valves and seats Z1 b or d 61 than to attempt at once to clean or repair those so defective.
and its seat-section, which are cheap and simply-constructed parts, may be removed and as readily replaced.
Avoidance of the necessity of turning for unscrewing the pipe- sections 27 or 27* and the parts therewith connected are deemed quite an important advantage, and especially in respect of the interchangeable portions of the ingress-valves where the part 27 may be disconnected from the valve-seat part 48, While such part 27 remains coupled to the re lnainder of the conduit 2', the section 27 and its coupling may be swung on the axis of the vertical portion of the pipe rising above the carbureter, and aside from the capability for the placing of the valve devices in their connected relations with other parts of the apparatus, as described, the constructions constitute very simple, inexpensive, and efficiently-operative valve devices.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
1. In a gas-engine, the combination with a cylinder having an opening through its wall, of removable valve devices, consisting of an annular bushing-piece, entered into said cylinder-opening, provided with a spider-supported tubular valve-stein guide, having a seat depression &7 in its outer end, and provided at its inner end with a valve-seat opening, the valve having its stern extended through said valve-stem guide, and a conduit or connection member having the angularlyturned hollow portion b with the hole 46 in its back, through which the valve-stem passes, the forward end portion thereof being entered in said depression, substantially as described.
2. In a gas-engine, the combination with a cylinder having an opening through its wall, of removable valve devices, consisting of an annular bushing-piece screwing into said cylinder-opening, and provided with a spidersupported tubular valve-stem guide, and having a seat depression 47 in its outer end, and provided at its inner end with a valve-seat opening, the valve seated therein having its stem extended through said valve-guide and provided with a shoulder 55, and a conduit or connection member having the angularlyturned portion with the hole 46 in its back, through which the valve-stem and its guide pass, the end portion thereof being entered in said depression, the nutv screwing on the end portion of the valve-stem guide against the back of said connection member, and the valve-spring 12, substantially as described.
3. In a gas-engine, the combination with a carbureter or gas-supplying apparatus and a cylinder having an opening through its wall, of removable valve devices, consisting of an annular bushing-piece screwing into said cylinder-opening, and provided with a spidersupported tubular valve-stem guide externally screw-threaded, at its extremity,having a seat depression 47 in its outer end, and provided at its inner end with a valve-seat opening, the valve seated therein having its stem extended through said valve-guide and provided with a shoulder 55, and a conduit or connection member 27 connected with said gas-supplying apparatus, having the angu-' HINSDALE SMITH,
