Application filed July 8, 1919. Serial no. 309,523.
To all whom it may concern: p Be it known that I, ALFRED JAMES Jone, subject of the King of Great Britaimresid ing at Thames street, Kingston upon- Thames, in the'county' of Surrey, England,
have invented certain new and useful Improvements in or Relating to Internal-Conn bustion or Explosion Motors or Engines, of which the following is a specification.
This inventionrelates to internal combustion or explosion engines or motors particularly of theclass known as two-stroke engines or motors,'and the chief object of the inventionis to increase their efficiency and improve and simplify their construction.
According to the present invention the inlet and exhaust ports or openings of the cylinder, or of eachcylinder, are controlled by one or more, sliding or' reciprocating mem bers or a sleeve arranged outside the cylinder cooling chamber or water jacket so as to be uninfiuenced by heat, and operated by or simultaneously with the piston. According to the present invention also there is pro vided, at theouter end of the cylinder, a chamber the end walls of which areformed respectively bythe end ofthe cylinder and a flange on the outerend of the piston, and the movement of the piston with its flange causes theformation in the chamber of a partial vacuum so that on communication being established between the combustion chamber and this chamber, at or about the end of the explosion stroke and conveniently through a port controlled by the piston, the residue of thespent gases is withdrawn and a fresh combustion charge induced, due to the reduced pressure in the cylinder. On the return or compression stroke, the gases in the vacuum chamber are expelled through a port controlled by one or other -ofthe aforesaid sliding members or the sleeve. In accordance with the present inventlon also the cylinder with its cooling jacket, in place of being bolted down to its bed plate or base'as is usual, is" suspended by its inner end within a surrounding casing secured to the bed plate and between the inner walls of which and the outer walls of the cylinder 7 jacket is a space for the aforesaid sliding member or members. V Referrlng to the accompanying drawings which show in sectlonal elevation, a cylinder or unit of an internal combustion engineembodying the. present invention, ,.A is'the sliding member or sleeve, B the cylinder, C the water jacket or cooling Iihamber, D the piston, E the vacuum cham- The cylinder B is provided with an inlet port or opening B, exhaust ports B B communicating with the atmosphere and an exhaust port B communicating with the vacuum chamber E. p
p In the embodiment illustrated the inlet and exhaust ports B B B are controlled in proper succession and in time relationby a single sliding member or sleeve A located between the outer walls C of the water circulatingchamber G and an outer casing F. The walls of the chamber O are so devised thatthe chamber is located entirely within or does not project beyond thelines of the cylinder. The valve-controlling sleeve A by the arrangement shown is removed from the 7 5 heating effects of the cylinder and is uninfluenced bythem. p a i The sleeve A is secured directly to the piston D by having its lowerend fixed in any convenient manner to a flange D on the outer end of the piston; the portcontrolling sleeve A is thus moved directly by and simultaneously with the piston D and there is no relative movement between them.
The inlet portB of the cylinder communicates with a fuel supply pipe G g by means of a conduit 6 which passes through the water chamber C, and in the sliding sleeve Ais an opening A which at the requisite point in the stroke or cycle opens communication between the port 9 leading to the pipe G and the conduit 6 leading to theport B The piston D is driven outward due to the explosion in the combustion chamber 13, and as it nears the outer end of the stroke the first port to be opened is the exhaust port B which is connected with an exhaust pipe Hby a conduit 1) passing through the water jacket and aconduit f in the walls of the easingF. In the wall of the. sleeve A is a port A which opens communication between the port 13 and the exhaust preferably before the piston reaches the outer end of its stroke and allows the gases in the cylinder to escape to atmosphere and the pressure in the cylinder to .fall approximately to atmospheric level. When the piston is at the outer end of its stroke the port A has passed the port B which isagain closed. WVhen the piston has reached the end of its-stroke it uncovers the exhaust port B and thus open communication between the interior of the cylinder and the vacuum chamber E.
The vacuum chamber E is formed by a flange B on the outer end of the cylinder 13, part of the walls of the sliding member A, the walls (Z of the. piston and the annular fiange D on the end of the piston D. During the initial part of the return stroke of the piston, the port B is closed and the vacuum chamber is placed in communication with the exhaust port 13* by means of the port A in the member A so that the gases remaining in the cylinder are expelled at the commencement of the compression or return stroke of the piston.
The outer casing F is secured to a base or bed J as is conveniently longer than the cylinder B, which it surrounds.
The inner end of the cylinder is secured to the upper nd of the casing F by bolts F or in other appropriate manner so that the cylinder is suspended from this outer casing F in place of being bolted down to a bed plate as has hitherto been the case. a B is a cap or end piece which is fitted into the end walls of the cylinder and be tween it and the end B of the cylinder is a water cooling chamber. The sparking plug Sis secured in the cap B and is in communication with the combustion chamher by a conduit 5 What I claim is 1. In an internal combustion engine the combination of a cylinder having inlet and exhaust ports, a piston, a water cooling chamber or jacket surrounding the cylinder, a port controlling member located outside the water jacket, means for moving the port controlling member simultaneously with the piston, and means for supportingthe cylinde'r from its inner end.
