UNiTED STATES PATENT OFFICE.
SIDNEY R. TREEN, OF CHICAGO, ILLINOIS.
GAS-BURNER.A
SPECIFICATION forming part of Letters Patent No. 703,625, dated July 1, 1902.
I A,Application filed December 4, 1901. Serial NoI 84.617. (No model.)
To all whom, iv' may concern:
Beitknown that I, SIDNEYR. TREEN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois,
. have invented a certain new and useful Improvement in Gas-Burners, of which the following is a specification.
My invention relates to fluid-burners such as'are intended to be used in connection with the burning of fluid gases, particularly for heating purposes.
My invention is illustrated in one forin in the accompanying drawings, wherein- Figure l is a side elevation of the burner. Fig. 2 is a longitudinal section. Fig. 3 is a section on line 3 3, Fig. 2; and Fig. 4 is a View looking down on the burner from the top.
Like parts are indicatedby the same letter in all the figures.
A is the body portion, which may be composed of one or more parts attached together or may consist of one integral mass. It is preferably in general form cylindrical.
B is a discharge end, preferably enlarged and outwardly Haring, as shown.
B is a combustion-chamber immediately back of. such discharge end and which in a general way is the point atwhich the combustion begins.
B2 is the passage, which I call the contraction7 and which serves to make a separation between the combustion-chamber and the mixing-chambers.
B3 and B4 are the mixing-chambers, and B5 is the introduction-chamber. As hereinafter explained, the several gases are introduced into the introduction-chamber B5 and then pass to the mixing-chambers B4 and B3. At the lower and middle portion of the introduction-chamber is the inlet B6, in this case being the inner opening of a pipe B7, which is screwthreaded onto the bottom of the introductionchamber. This, however, is only a matter of convenience in construction. This pipe is formed in this case integral with the support B8, which is open atbothv sides, so as to admit air within it, whence' the air passes up through the pipe B7. The lower portion of the support BS is preferably screw-threaded upon the pipe B9, which is itself provided with an upwardly-extending discharge-tip B10. This tip preferably discharges in the middle of the open space formed in the support B8 and below and a short distance from the inlet B6. The bottom ofA the.introduction-chamber B5 is indicated at C and consists of adiaphragm which may or may not be integral with the cylindrical portion of the burner. This diaphragm receives the screw-threaded pipe B7 'and is also provided with a series of secondary inlets D D. These secondary inlets are arranged in the form of a circle about the bottorn and at a considerable distance from the central inlet. The head of the cylinder about the Adischarge ond may be enlarged, if necessary, as indicated at E.. A spreader-plate F may bev placed in the discharge end of vthe burner, the same being secured in position by the screw-bolts G G. As previously suggested, these several parts may be greatly changed without departing from the spirit of myinvention, and some of themmay be omitted while employing others.
The use and operation of my invention are as follows: The gas is first turned on through the pipe B9 and tip B10, the pipe being properly controlled by a valve. (Not here shown.) This gas, being discharged under a certain amount of pressure, rushes up through the pipe B6, carrying with it a quantity of air, which travels as indicated by the small arrows. If now the apertures D D were not employed or if there were no secondary inlets, a certain amount of air would be carried in, and ifI the gas should be lighted at the discharge end combustion would take place, and the device would operate gas-burner for heatingsorothersuchpurposes. lhavefound, however, that in the attemptthus to introduce airrwith the gas at a single opening or at the opening or openings through which the gas itself is admitted the results are decidedly unsatisfactory. It is extremely difficult to secure in this manner the introduction of a suliiciently large amount of air inproportion to the amount of gas used to get the desired result in an economic manner. One of the steps in my invention is therefore to employ the contraction'B2 or the reduced passageway between the gas-supply andtheapoint where it is burned. The diameter of this contraction must be varied in accordance with the other conditions which prevail and in any particular burner is only to be learned by ex- IOO periment or careful investigation. The result of this passage is to confine the combustion-chamber to a point beyond the contraction, and to increase the supply of air at that point I supply the other or secondary inlets, in this case arranged in a circle about the primary inlet. As the gas burns in the chamber B and beyond it room is made for more air, and a very large quantity of air can thus be drawn up and consumed without increasing the consumption of gas. The result is to give a high and perfect combustion at that point, with an extraordinarily large amount of air or oxygen in proportion to the amount of gas used.
The form and shape of the several chainbers maybe considerably varied, although the particular form, shape, and proportions here shown l have found to be Very effective by actual experiment. lt is necessary With each SIDNEY R. TREEN.
