Specification of Letters Patent.
Patented'jkugl, 1916.
Application filed March 9, 1915. Serial No. 13,151.
To all whom it may concern Be it known that I, LINDSAY FILLAN Born,
of No. 30 Surrey road, Hawksburn, in the State of Victoria, Commonwealth of Australia engineer, have invented certain new and useful Improvements in High-Pressure Gas-Lighting Systems, of which the following is a specification.
This invention relates to improvements in high pressure gas-lighting systems and is directed particularly to the provision of a simple and extremely efficient method of controlling the delivery of air and gas to a gas burner or jet whereby a more perfect light will result.
The method of effecting the admixture of gas and air embodied in the present invention consists in supplying compressed air and gas through separate passages or pipes to a point where the said passages are controlled by a three-Way tap or other similar contrivance.
The compressed air is directed through a passage in the tap to a pipe leading to a burner or jet and as the air is passing rapidly through the tap it draws a regulatable quantity of gas from the gas pipe. The quantities of air and gas delivered to the pipe leading to the burner or jet can be regulated to give a satisfactory combustible mixture Which is then conveyed to the said burner or jet free from fluff or dust that may impregnate the surrounding atmosphere.
The invention is embodied in means whereby the forcible projection of air past a given point will cause gas to be admixed therewith in a quantity sufficient to make a highly combustible mixture which will burn freely without the necessity of providing an air draft near to or at the burner or jet.
In order that the invention may be readily understood reference will now be had to the accompanying sheet of explanatory drawings, wherein:
Figure 1 is a view in side elevation of an apparatus embodying the invention. Fig. 2 is a view in perspective of that part of the apparatus which controls the supply of air and gas. Fig. 3 is a view in sectional side elevation of Fig. 2. Fig. 4: is a view in sectional elevation of Fig. 3 taken on the dotted line II.
Throughout the drawings like characters of reference have been employed to indicate similar or corresponding parts in the different views and the letter a designates a threeway cock which is mounted in a body a having connections with a compressed air pipe and a gas supply pipe I) and 0 respectively.
The body of the three-way cock has three separate passages (Z, c and f formed therein and corresponding passages (Z 0 and f are formed in the said cook.
The compressed air pipe .7) is fitted to the passage (Z and the passage f is fitted with the gas supply pipe 0. The compressed air pipe is arranged in communication with an air compressor (not shown) of any approved design and if preferred a storage chamber 9 can be located at any point in the length of said pipe to insure an evenness of pressure at the cock.
The air passes very rapidly through a narrow part of the passage (Z in the three-way cock with the result that it is forcibly projected into the passage 6 which is fitted with a pipe h leading to-an incandescent burner i or the like.
The passage f in the body of the threeway cock is provided witha screw plug y or the like adjustable device for controlling the flow of gas therethrough from the pipe 0 to regulate the richness of the combustible mixture.
The forcible'projection of air past the inner end of the passage f causes a desired quantity of gas to be drawn into the body of the three-way cock and to be thoroughly mixed with the air in the passage 6 or in the pipe A leading to the burner thereby making a highly combustible mixture which will burn without an air draft.
A bypass in is rranged to lead from the gas passage f to a point adjacent to the burner and this by-pass is fitted with an earthenware cap Z having a small orifice m through which a small quantity of gas may pass to form a pilot light in the ordinary way. I
A ball valve n is fitted Within the passage 7 to prevent" back fire should the air and gas become choked in the pipe leading to the burner or is prevented from passing freely to the said burner. The said valve is arranged to close against a seat formed in the lower end of the pipe 0 should any back pressure occur in the passage and it will be obvious that the valve can be of a different construction to that shown or be arranged in a different manner.
The air and gas are thoroughly mixed priorv to delivery to the burner and there is no liability of dust or dirt being carried to the incandescent mantle to impair the same. The gas supply pipe can be placed inside the air supply pipe and the gas in the supply pipe is kept at ordinary. gas lighting pressure. The richness and quantity of the mixture delivered to a burner is governed by the velocity of the air passing and the size of the passage 7 and if desired one or more burners can be supplied by one mixing apparatus In addition to lighting purposes the apparatus hereinbefore described Will be found highly eiiicient for use with difierent forms of gas-heated utensils as laundry irons, stoves and the like.
The invention Will be particularly adaptable for lighting factories and other buildings Where there is an excessive draft or a considerable amount of fluff or dust in the atmosphere.
What I do claim is 1. In high pressure gas-lighting systems a gas supply pipe and a compressed air supply pipe leading to separate passages in the body of a threeway cock, a junction between the inner ends of said passages, a screw for adjusting the size of the opening from the passage leading to the gas supply pipe, a third passage in the body of the three-Way cock leading from the junction of the first mentioned passages, and a pipe leading from the last mentioned passage to a. burner, substantially as described.
2. In high pressure gas-lighting systems a body of a three-way cock having separate passages formed therein for the admission of compressed air and gas, a third passage in the body, a three-way cock having passages arranged to correspond to the passages in the body, a screw to control the flow of gas from its respective passage, and a valve to prevent back pressure in the gas passage, substantially as described.
3. In high pressure gas-lighting systems a body of a threeway cock having separate passages formed therein for the admission of compressed air and gas, a third passage in the body, a three-Way cock having passages arranged to correspond to the passages in the body, a screw to control the flow of gas from its respective passage, a valve to prevent back pressure in the gas passage, and a by-pass leading from the gas passage to a point adjacent to the incandescent mantle of a burner, substantially as described.
In testimony whereof I afiix my signature in presence of two Witnesses.
