CARBURETER FOR EXPLOSION-ENGINES.
SPECIFICATION forming part of Letters Patent No. 742,920, dated November 3, 1903.
Application filed April 10. 1903. Serial No. 152044. (No model.)
To all whom it may concern.-
Be it known that I, FREDERICK HUGH SMITH, engineer, a subject of the King of Great Britain, residing at Manor House, Datchet, near \Vindsor, England, have invented certain new and useful Improvements in Car bureters for Explosion-Engines, of which the following is a specification.
According to this invention a certain length (preferably adjustable) of a reciprocating rod which dips into the liquid hydrocarbon is exposed to the current of incoming air, and the film of liquid upon it is vaporized. Since the thickness of the film'of liquid brought up on the rod at each reciprocation is substantially constant, the supply of vapor is extremely regular and can be readily varied by altering the length of the wetted surface of the rod exposed at each reciprocation. The arrangement I prefer to adopt is shown in vertical section in the drawing.
The carbureter consists of avertical cylindrical vessel a, divided into two chambers by a transverse diaphragm b. The lower chamber has in it an annular float 0, working on a tubular guide fixed to the diaphragm b. This float acts on the .levers d and regulates the admission of liquid through the Valve e and keeps its surface at a constant level in the ordinary manner. in it a perforated disk f, having fixed to its under side a sleeve g, which passes through the diaphragm b and descends into the axial hole of the float dipping into the liquid.'
Since this hole is central, the height of the liquid in it is practically constant in spite of Air is sucked by the engine through the inlets h into the any tilting of the apparatus.
upper chamber beneath the disk f, which is thereby raised, drawing the wetted sleeve g into the upper chamber and exposing it to the blast of air. The mixture of air and vapor passes to the engine through the pipe 1'.
Above the disk is an adjustable spring-buf- The upper chamber has.
The rod 7- has fixed to it a quick-threaded screw m, working in the nut 02, which carries the'bufferj, so that by turning the rod the buffer is raised and lowered, the nut 11 being prevented from turning by pins 0, which e11- gage with slots in the walls of the vessel a.
The vessel a'is surrounded by a jacket 1), heated by the products of combustion, and the air-supply pipes h to the upper chamber are led through this jacket. Further, air can be added to the mixture by the valve q.
r is wire-gauze to prevent the flame from the engine passing back into the carburetor and to break up any liquid petrol.
The rod 70 may be turned by the engine- ,governor in any convenient manner to regulate the speed of the engine by varying the supply of hydrocarbon; but I generally dispense with the ordinary governor, making the engine self-governing, as hereinafter described, the rod is being in this case turned by hand only for the purpose of altering the speed at which the engine is set to run.
The engine is made self-governing for any speed at which it is set to run by a peculiar form of valve. This valve consists of a pair of disks 3 and t, perforated with holes, which are not in similar positions in the two disks,
so that the nearer the disks are together the more is the passage of gas past them impeded, while when they are pressed into contact with each other the passage is completely stopped. The upper disk 3 is fixed to the nut 01, while the disk 25 is loose upon it and has studs u fixed to it, which pass through holes in the disk 3 and are pressed downward by the Washer 0), which is acted on by the spring w. The faster the engine runs the greater its suction and therefore the more it tends 'to raise the disk 25 against the spring 10, and
