Specification of Letters Patent.
Application filed January 18, 1913. Serial No.,742,773.
To all whom. it may concern Be it known that I, PERCY HUTCHINSON, a subject of the King of Great Britain and Ireland, and a resident of Putney, London, England, have invented new and useful Imnrovements in Carburetors, of which the following is a specification.
This invention relates to improvements in carbureters and their accessories for vaporizing petroleum and similar heavy hydrocarbons, which carburetors are of that known type in which. the vapors from the petroleum or the like (hereinafter referred to as petroleum) are water cooled on emerging from or leaving the carbureter proper and then have mixed with them any re uired proportion of atmospheric air before eing delivered to the engine. In such carbureters as before'known various degrees to which the cooling of the vapors should be carried have been proposed. Sometimes the cooling of the vapors would be too great and result in condensation ofthose which should have reached the engine, while in other cases the cooling would not be suflicient and would permit the va 01's to certain of the heavier components 0 the petroleum to reach the engine in an insufficiently vaporized condition,. which certain component vapors are very undesirable in the engine until they have been sufiiciently vaporized.
According to this invention the cooling appliance is so supplied with water and is of such dimensions and relative proportions to the carbureter and the heating appliance, that it will effect the condensation of those heavy vapors whose presence in the engine is undesirable, but it will only cool, without condensing, those vapors which are desirable in the engine, and it is so disposed, arranged or provided with accessories that the condensation products can not run. or be carried forward into the engine but must again flow into the carbureter where they are again vaporized. The carbureter can be drained at suitable periods to run off the condensation products, if any, which are not of a nature to be eiiiciently vaporized in this apparatus. As has before been known part of the air necessary for the formation of the explosive mixture may be drawn through the carburetor with the vapors.
The accompanying drawings illustrate a convenient form of carburetor constructed according to this invention and will now be referred to.
Figure 1 is a central vertical section of the carbureter. Fig. 2 is an end elevation of the same, shown partly in section.
A is a U-shaped tube contained within a heatlng chamber B through which the products of combustion from the engine pass by means of ports or. openings C, C. The upper end-of one ofthe limbs a of the tube A-the down take limb-has its opening controlled by a valve D which governs the inlet of petroleum and of air. The valve has an adjustable closing spring D disposed around its stem and is drawn off its seat by the suction of the engine. In the seat of the valve is a petroleum inlet duct E so placed that when the valve is down on its seat the duct is closed by the valve. When the valve leaves its seat both petroleum and air are admitted to the downtake limb of the tube A, the air entering through the opening or port F. When the valve is on its seat the entrance of both air and petroleum is prevented.
The petroleum which enters and passes down the downtake limb then passes uptake limb a (being vaporized in its passage through the tube A by the heat communicated to such tube from the products of combustion of the engine or from heat applied in any other suitable manner), and emerges from the upper end of the limb a as vapor mixed with air. This charge then passes upward through a cooling tube G surrounded by a water jacket G The tube G passes in a curve upward and sidewise from the top of the uptake limb a until it comes over the end of the downtake limb a. The tube is so shaped that any condensation products produced in it fall down it into the uptake limb a and through that limb to the bottom of the U-shaped tube A. The tube G is of such dimensions and relative proportions to the carburetor and the heating appliance, and is so supplied with cooling water in the jacket surrounding it, that all undesirable vapors are condensed while the vapors desirable for use in the engine are-not condensed. As an example to effect this the temperature of the vapors or the like may be reduced to 70 C. Ascrew plug fitted into the hole H at the bottom of tho carhureter may be withdrawn at any time to draw off condensation products.
To assist in preventing any products of condensation in the tube G which may be lodged on its surfacebeing drawn forward Patented Apr. 20, 1915.
by the rush of vapor into the induction pipe leading to the engine, the upper end of the tube G is furnished with a'small coned nipple J the coned surface or end of which prevents any creeping or other passage of condensation products along the surface of the tube past its end into the engine induction 1 e. p ii is a spring controlled suction air admission valve by which the admission of atmospheric air to the induction pipe is controlled.
The springs of the valves D and K may be so adjusted ,as to give any desired relations between the volumes of air admitted by each. They may conveniently be set for use with ordinary lighting petroleum under normal running conditions, that the valve D may admit one-ninth of the bulk of the air admitted by the valve K, but this is to be taken merely as an example and can be widely departed from.
M indlcates the needle valve by means of which the supply of petroleum may be con trolled. Its head M is preferably milled and graduated so that it can be set relatively to a pointer or indicator N.
O O are pipes from diflerent reservoirs,
respectively for supplying petrol for startvalve K, and the connection is made in such a manner that as the induction pipe throttle is closed the throttle in the air pipe also has a closing movement communicated to it, as it is found that a richer mixture is re quiredunder such circumstances when theengine is running light than when itis .running with the throttle full open to meet its requirements:
F and Ktindicategauze caps which are fitted over'the opening or portsaof the air admission pipes F and K p "In: the heating chamberof the carbureter engine are sweeping through it.
are ports or openings A closed by plates when the carbureter is working normally and the products of combustion from the Through these'openings, however, with the plates removed access is given to the interior of the heating chamber to enable the tube A. to be heated by a blow lamp or the like for starting the engine. If desired, however, the engine may, at starting, be run on petrol, until the heating chamber is sufiiciently heated by the products of combustion to vaporize petroleum, when the supply of petrol is cut off and the petroleum is turned on.
What I claim is 1. A carbureter for heavy liquid hydrocarbon, comprising in combination a heating chamber for vaporizing such hydrocarbon, an inlet in such chamber for the hydrocarbon, an inlet in such chamber for primaryair, a delivery pipe for the vaporized hydrocarbon from such heating chamber leading to the engine induction pipe, an inlet to such delivery pipe for secondary air, a cooling means combined with the delivery pipe and operating to condense the vapors which are not in a desirable condition for use in the engine, and means for preventing the passage of the products of condensation to the induction pipe, the heating chamber and the delivery pipe being so relatively disposed that condensation products in the delivery pipe flow back intothe heating chamber, substantially as set forth.
2. A carbureter for heavy liquid hydrocarbon, comprising a vertical U-shaped tubular heating chamber, inlets for hydrocarhem and primary air at the upper end of one limb of the U, a curved delivery pipe leading up from the upper end of the other limb of the U and curving over the first limb, an inlet for secondary air at the overhanging end of the curved delivery pipe, and a cooling jacket disposed on such delivery pipe, substantially as hereinbefore described In witness whereof I have hereunto set. my 4 hand in'the presence of two subscribingwitnesses.
