SPRAY- LAMP.
SPECIFICATION forming part of Letters Patent No. 496,450, dated May 2, 1893.
Application tiled July 20, 1889i Serial No. 318,116. (No model.)
To all whom t may concern:
Be it known that I, ALFRED SHEDLOCK, a citizen of the United States, residing in Jersey City, in the county of Hudson, State of New Jersey, have invented certain new and useful Improvements in Spray-Lamps, ot' which the following is a specication.
Myinvention relates to that class of lamps 1n which oil, generally hydro-carbon oil, is supplied under pressure of compressed air in connection with a jet of compressed air that sprays the oil, the two being thoroughly mingled and burned with a brilliant flame. Usually in such vlamps the oil and air are supplied from concentric nozzles. In the lamp herein described a different method of operation is practiced: The oil is as usual supplied under pressure but the air is supplied at atmospheric pressure at the nozzle or burner and the oil is sprayed and thoroughly mingled with the air by means of a jet of vapor preferablygenerated from some hydro-carbon or some product of petroleum, by the heat of the llame of the lamp; the oil or vaporizable fluid for this purpose being automatically supplied preferably by a charge of compressed air contained in the body or chamber of the lamp. By preference the burner is formed of three concentric nozzles, a central one for the oil, an intermediate one for the air and an exterior one for the vapor which acts with an aspirating action, both on the oil and the air so that the oil, air and vapor are all thoroughly mingled.
So far as I am aware I am the first to employ a vapor generated by the heat ot' the lamp to act upon the oil, or oil and air as above described thereby dispensing with the necessity of a constant supply of compressed air and adapting the lamp for isolated use.
The accompanying drawing is a vertical section of a lamp embodying my invention, some of the parts being in elevation.
The tank or combined oil and air reservoir A is shown as divided by a horizontal partition into two chambers. A pressure reducing valve B of any suitable and ordi-nary construction in this partition opens downwardly and acts to maintain a uniform pressure upon' 'the surface of the oil in the lower chamber. This pressure may vary with the weight and character of oil used; for petroleum or its lighter products a pressure of-say about tifteen pounds, more or less, is suitable. An air pump O of any ordinary construction may be mounted upon the vessel A, and by it air may be compressed into the upper chamber to any pressure in excess'of that to be maintained in the lower chamber, say forinstance .thirty pounds, andv the desired pressure is maintained upon the surface of the oil in the lower chamber by the action of the reducing valve B. Of course the greater the pressure in the upper or air chamber the longer a lamp will run without a further charge of compressed air. Oil taken from near the bottom of the lower chamber by a pipe D is led to the bottom of the interior tube E-of the concentric tubes E F. At the upper end the tube E has a contracted opening or nozzle in which a valve rod e having a conical shaped end works. The lower end of this valve rod passes through the head G of the tube E, being suitably packed, and is screw-threaded and provided With a handle or wheel g by which it is adjusted vertically to regulate the supply of oil at the valve or burner. Grooves c are formed in the rod c near its upper end to permit of the low of the oil past the bearing of the rod in the tube E at that point. Oompressed air may pass from the upper chamber of the tank A by the pipe H through a two way cock lz to the outer tube F which is also formed at the top with a contracted opening or nozzle surrounding the nozzle of the interior. oil tube.
The lamp constructed as thus far described may be operated in the following manner: The oil valve e and the air cock h being closed air is pumped into'the upper chamber of the vessel A to the desired pressure say thirty pounds, more or less, the pressure upon the oil in the lower chamber depending upon the adjustment of the reducing valve being-say fifteen pounds, more or less. If the two-way cock h is now turned so that air may pass through the port h to the pipe Hand tube F, c
and the oil valve c be also opened by manipulating the vhandle g, the lamp may be lighted and will burn properly' as long as the supply of compressed air lasts. In order however to prolong the operation of the lamp I provide the following arrangement: In the upper chamber is arranged a small tank or holder I IOO in which some liquid or oil, yielding a combustible vapor such for instance as naphtha or other product of petroleum, is placed. A pipe i provided with a suitable cock connects the top of this holder with the top of the lower or oil chamber in the vessel A, and a vertical pipe z" having a suitable cock extends from the bottom of the holder I into the closed chamber K formed by the hollow walls of the combustion chamber K', supported above the air and oil outlets by a frame or annular support K2. A pipe K having a suitable cock 7o leads from the chamber to a conical chamber L surrounding the contracted ends or nozzles of the tubes E F,its pointed or truncated end being provided with an opening Z constituting the burner proper, through which the mingled oil, air and Vapor pass. The lamp having been lighted as before described the cocks in the pipes z', t" are opened sufficiently to permit a small quantity of liquid from the holder I to be forced by the pressure of air in the oil chamber of the tank A to the chamber K within the walls of the combustion chamber K. The heat of the flame of the lamp vaporizes the oil or liquid thus admitted to the generator K, and when the cock 7.a is opened the vapor passes under considerableprcssure down through the pipe 7o into the chamber L and acts with an aspirating action upon the oil and air, all three being thoroughly mingled and burned in the flame of the lamp. rlhe two Way cock 71, in the air pipe H may now be turned so as to close the p port h leading from the compressed air` chamber into the pipe ll and open the port H2 leading from the atmosphere through the center of the plug to the interior of the pipe A as indicated bythe arrow. The compressed air now Serves to continuously supply oil to the burner and oil from the holder I tothe vaporizer. The vapor continuously passing as before described into the chamber L serves -to spray the oil and draw sufficient air from to the oil pipe D as indicated by dotted lines at X. Sufficient compressed air maybe supplied at one time to insure the operation of the lamp for a considerable period.
The method of operation carried out by the apparatus herein described is claimed in auother application filed by me.
I claim as my invention l. The combination of the air and oil supply pipes or nozzles, the vapor generator located above them and surrounding the fiame of the lamp a pipe or passage leading from the vapor generator to the nozzles, an oil tank, an air reservoir, and separate connections conveying oil or other combustible duid to the oil nozzle and to the vapor generator, and a pipe or connection leading directly from the air reservoir to the nozzle.
2. The combination of the vessel A, an air pump, the holder l, the pipe connecting the holder and the air space of the vessel A, the vapor generator, the pipe fil connecting the vapor generator and the holder I, the burner and its concentric pipes E F, and the pipe D leading from the vessel A to the oil pipe E, substantially as set forth.
3. The combination, of the vessel A, the diaphragm and reducing valve therein, an air pump C, the holder La pipe 'iconnectingsaid holder and the vessel A below the diaphragm, the vapor generator K, the pipe il connecting said generator and the holder I, the chamber L, the pipe connection between said chamber and the vapor generator, the pipe D, and the air and oil supply pipes, substantially as and for the purpose set forth.
Lt. The combination of the oil and air nozzles, the oil and air reservoirs, pipes connecting the nozzles with the reservoirs, the generator located above the nozzles, a pipe connecting the vapor generator with an oil supply reservoir, a pipe leading from the vapor generator to a nozzle arranged at the air and oil nozzles, and a valve in the compressedair supply pipe interposed between the nozzle and the air reservoir.
In testimony whereof I have hereunto subscribed my naine.
ALFRED SHEDLOCK.
