VAPORIZER FOR INTERNAL-COMBUSTION ENGINES.
Specification of Letters Patent.
PatentedAug. a, race.
Application filed May 21, 1918. Serial No. 235,868.
To all whom it may concern:
Be it known that-We, Gnonon SPICER and EDWARD CHARLES SYDNEY CROXSON, subjects of the King of Great Britain and Ireland, respectively, whose post-ofiice addresses are 93 Hatton Garden, London, E. (1., England, and Vulcan House, Southend-on-Sea, Essex, England, have invented certain new and useful Improvements in Vaporizers for Internal-Combustion Engines, of which the following is a specification.
This invention relates to apparatus for vaporizing parafiin oil or similar liquid fuel foruse'in internal combustion engines and a carbureter for use therewith and has for its object to provide a vaporizer that shall be simple in construction, neat in appearance, suitable for any type of motor or engine driven by air carbureted by liquid fuel, eflicient and economical in'use giving perfect vaporization with maximum power at all speeds, easily cleaned and generally superior to the exhaust paraffin Vaporizers previously proposed.
he vaporizer comprises an outer casing of tubular form closed at opposite ends by plates or covers having respectively an inlet and outlet for the exhaust gases from the engine, and an inner casing or tube inclosed within the outer casing and provided with inlet and outlet pipes by which the fuel is conveyed from the carbureter to the inner casing and from thence to the motor.
The cross sectional dimensions of the inner casing are such that when in position in the outer casing an annular space or passage is left all around it and open ended pipes also pass through it, these pipes and the annular space aforesaid serving to convey the exhaust gases through the vaporizer in such a Way that a great part of the heat therefrom is transferred to the fuel as it passes through the inner casing to thoroughly vaporize the same.
In the accompanying drawings.
Figure 1 is a vertical section of a vaporizer constructed according to this invention.
Fig. 2 is a transverse section of the same taken at 2-2 Fig. 1 and Fig. 3 is a transverse section showing a slightly modified form of construction.
As shown in Figs. 1 to 3 the outer casing of the vaporizer consists of an iron tube a with a jacket or lagging of asbestos a in cased in a thin brass covering 6. End
plates or covers 0 are fixed in position by bolts (Z extending through the lagging space from end to end of the casing through the covers and provided with nuts 03 at the ends outside the covers. The-innercasing or tube 6 is made of iron or other metal and is closed by end plates 6 e held in position by two open ended tubes f, f for conveying a portion of the exhaust gases through the inner casing, these tubes being flared or enlarged at the inlet ends 7 and screwthreaded to receive nuts 7 at the outlet ends. Near one end of the casing the inlet and outlet tubes 9, g for the fuel are connected, the inlet tube 9 being provided with a flange 9 for connection to the carbureter hereinafter described while the other tube 9 leads to the induction pipe or manifold of the engine. Both the fuel inlet and outlet tubes pass through the wall of the outer casing and they may be in line as shown in Figs. 1 and 2 or at a right angle as shown in Fig. 3 or other convenient angle to each other.
A baflie plate 72, fixed in the inner casing 6 between the tubes f is arranged to cause the fuel to pass through the end at which it enters to the opposite end and back again before leaving at the outlet, during which it is vaporized by contact with the heated walls of the inner casing and the heated tubes f, f.
All the metal parts with the exception of the brass covering Z; are preferably made of wrought iron and the whole can be easily assembled or taken apart for cleaning purposes when necessary.
e claim 1. Avaporizer comprising a tubular outer casing having closed ends provided with inlet and outlet tubes, a tubular inner casing of less diameter than and arranged in the outer casing, said tubular inner casing having closed ends, pipes extending longitudinally through said inner casing and open at the ends, fuel inlet and outlet pipes extending transversely through the outer casing and connected to the inner casing at a point near one end thereof, and a baflie in said inner casing and extending from said end thereof to a point near the opposite end thereof. I
2. A vaporizer comprising a tubular outer.
casing having closed ends provided with inlet and outlet tubes, a tubular inner casing of less diameter than and arranged in the outer casing,
said tubular inner casing LMQAM having detachable closures at its ends,
open-ended pipes extending longitudinally through said inner casing and through the closures thereof and detachably securing said closures in place, fuel inlet and outlet pipes extending transversely through the outer casing and connected to the inner casing at a point near one end thereof, and a baffle in said inner casing and extending from said end thereof to a point near the op- 10 posite end thereof.
In testimony whereof We have aflixed our signatures.
