GASOLENE-ENGINE.
Specification of Letters Patent.
Patented Oct. 31, i905.
Application filed EebruaryS, 1905. Serial No. 244.769.
To IJ/Z whom t may con/cern:
Beit known that I, HENRY EUGENE THOMP- SON, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Gasolene Engines, of which the following is a specification.
My invention relates to certain new and useful improvements in gasolene-engines; and it more particularly relates to gasolene-engines of the two-cycle type. The present invention has for its object to provide an engine of this character of a very simple construction which will readily and eectively serve its intended purposes.
My invention also has for its object to provide a special type of valve controlling the admission of working agent into the explosionchamber in such a manner to prevent the new charge becoming prematurely ignited as it passes from the valve into the explosion-chamber.
Vith other objects in view, which will be hereinafter more4 fully apparent,the invention includes certain novel construction,operation, and arrangement of parts, all of which will be first described in detail and then specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which- Figure l is a perspective view showing my invention as applied for use as an automobileengine. Fig. 2 is a longitudinal section thereof. Fig. 3 is a longitudinal cross-section -on the line 3 3 of Fig. 2. Fig. 4 is a cross-section on the line 4 4 of Fig. 2. Fig. 5 is a similar view on the line 5 5 of Fig. 2. Flg. 6 is a detail sectional view of the inlet-valve. F ig. 7 is an enlarged sectional View of the improved form of valve in the piston. Fig. 8 is a side elevation thereof. Fig. 9 is a detail view of the wire-gauze member hereinafter referred to. Fig. lO is an inverted plan view of the valve shown in Fig. 7.
Referring now to the accompanying drawings, in which like characters of reference indicate like parts in all the figures, l designates the engine-casing, which is preferably constructed in two sections, the fly-wheel-casing section lu and the piston-casing lb, and these two sections l lb are bolted or otherwise secured together, as at le, by the rims or flanges lc ld of the sections l lb, respectively.
The piston-casing lb is centrally bored to form a chamber lg, divided into two parts by the piston 2, one part forming the explosionism which is located at the closed end of the.
casing lb and which igniting means may be of the electric type, as shown, or of any other approved type, as the same per se forms no part of my present invention.
The piston 2 comprises a cylindrical member having an end (the end adjacent the explosion-chamber) closed by a wall or diaphragm 2, -which'wall or diaphragm 2 is centrally apertured, as at 2b, and screw-threaded to receive the valve 5, which will be hereinafter more fully explained and again referred to.
2c 2e designate internally-projecting radial hubs which are formed on the interior of the pistons and which are longitudinally apertured, as at 2d 2d, to receive the transverse shaft 2e, which shaft 2e also passes through the walls of the pistons 2 and also through the bearing portion 6*1 of the piston-rod 6, which piston-rod bearing 6 is provided with an internal lining 6X of bearing metal, as clearly shown in Fig. 2 of the drawings.
The ily-wheel chamber l"L has lateral bearing portions lx lx, lined with bearingk metal ly ly, to receive the drive-shaft 7 7, and the ends 7n 71 of the said drive-shaft 7 7 project into the casing la and into the fly-wheel chamber lz and receive the fly-wheels 8 8. The fly-wheels 8 8 are suitably keyed to the ends 7' 7 l of the shafts 7 7, as at 8 8a, so that the fly-wheels and shafts will turn together. The ily-wheels 8 8 are cored out, as at 8h 8h, to form hollow chambers within the fly-wheels, which chambers are, however, so formed as to be air-tight to prevent the working agent entering therein. The reason I prefer to core out the fly-wheels is that by so doing I confine the greater portion of their weight at their periphery 8c 8C, and thereby increase their eliiciency. I The ily-wheels 8 8 are spaced apart to leav a passage a between `them and allow the IOO IIO
piston-rod 6 to also pass between the flywheels 8 8.
8d 8l designate hubs integrally formed with and passing through the ily-Wheels, and these hubs receive the communicating shaft 9, which shaft 9 also passes through the bearing en'd 6h of the piston-rod 6. The hubs 8d 8d are also countersunk, as at 8e 8e. to receive the ends 6c 6c of the bearing portions 6b 6b of the piston-rod 6, as clearly shown in Fig. 2 of the drawings. The bearing 6b is provided with a suitable lining 6d of bearing metal.
The casing-section l is preferably formed in two halves, as shown in the drawings, to permit the ready assembling of the parts therein, and these two halves 1r 1r may be bolted or otherwise secured together, as at ls and as clearly shown in Figs. l and 2 of the drawings.
lOdesignates an inlet-valve of any approved construction for admitting the working agent to the fly-wheel chamber, and the said valve l() is in the nature of a one-way valve arranged to operate only to admit the working agent into the ily-wheel chamber and prevent its escape therefrom due to back pressure.
The valve 5, which is of a special construction, forms an essential part of my invention and comprises a cylindrical body 5, forming the valve-casing and having a rim 5b and a threaded portion 5t for engaging the threaded aperture 2b of the piston 2. The valve-easing 5*L is also provided with a transverse web 5c to form the valve-seat 5d for the head 5e of the valve proper, and the valve-head 5e has an integrally-formed stem 5g, which carries a diskv portion 5h at its opposite end and is provided with a coil-spring 5, which engages said disk and also engages a disk 5u, which is held in the seat 5D of the casing 5, and the disk 5 is provided with a valve-stem bearing 5r, as clearly shown in Fig'. 7 of the drawings. The valve-casing 5fL is extended to form a chamber below the web 5C, and this chamber is in communication with the interior of the piston 2 by means of the apertures 5x of the wall of the valve-casing 5*. Arranged in the chamber below the web 5c is a gauze diaphragm, which is preferably bent into a spherical section, and the gauze member 5y has its peripheral rim seated in the groove 5z on the under side of the web 5, while the valve-stem-bearing member 5r passes through an aperture 5v in the diaphragm 5".
rIhe disk 5u is held in position by swaging over the edge of the valve-casing in several places, as at 51. (See Figs. 7 and l0 of the drawings.)
By providing' the diaphragm 5y in the valve member 5 I prevent the working agent within the piston 2 and within the fly-wheel chamber from becoming` ignited by the burned mixture in the explosion-chamber as the new mixture passes through the valve 5 into the explosionchamber after the burned mixture has been exof the arrow in Fig. 2.
hausted. This prevents the premature ignition of the new charge.
So far as described the manner in which my invention operates will be best explained as follows: Assuming the parts are in the position shown in Fig'. 2, the exploded charge having passed out of the explosion-chamber through the exhaust-aperture 1h lh and a new charge as having entered through the valve 5 into the explosion-chamber while the piston 2 is commencing its stroke in the direction of the arrow in Fig. 2, now as the piston 2 con'- tinues its stroke the apertures lh lh will be closed, and the piston 2 will compress the new charge ahead of it. At the same time the flywheel chamber will be filled with working' agent entering through the valve l() as the piston moves forward. As the piston reaches the end of its stroke in the direction of the arrow a in Fig. 2 the compressed charge is exploded, and thus forces the piston on its return stroke in the direction opposite to that As the piston continues on its return stroke it compresses the working agent within the ily-wheel chamber, which, however, cannot pass through the valve 5 until the exhausts 1h lh are uncovered by the piston 2 and the burned mixture has passed out of the explosion-chamber. As soon as the burned mixture passes out of the apertures 1h l11 the valve 5 automatically opens to admit the compressed charge of new working agent to the exploding-chamber, it being understood that the piston 2 closes the apertures 1h 1h as soon as the burned mixture passes out. The operation of the engine then continues as before.
From practical experience l have found that in using an engine of this type without the screen-diaphragm in the valve 5 the working agent becomes ignited asit passes through the valve 5, and when I use the wire-gauze screen such ignition of the working agent does not occur, the screen serving as a fireshield between the explosion-chamber and the ily-wheel chamber.
The water jacket around the explosionchamber serves to keep the saidchamber cool and prevent overheating thereof.
