Gas mxm Specification of Letters Patent.
Application filed January 8, 1921. Serial No. 485,826.
To all whom it may concern:
Be it known that I, JOSEPH NEEDHAM, a
- subject of the King of Great Britain,and
' particularly to devices of this class adapted for use in connection with fuel gas furnaces and like appliances, and the object of the invention is to provide a device of the class specified composed of a suitable body portion having a fuel chamber,a mixing chamber formed therein with an air chamber therebetween and an adjustable tubular member which forms a part of the mixing chamber of the device, and which is provided with an outwardly flaring throat in connection with which a fuel discharge device or nozzle, in communication with the fuel chamber, operates, and with this and other objects in view the invention consists in a device of the class and for the purpose specified which is simple in construction and operation, and which is constructed as heremafter described and claimed.
The invention described and claimed herein is an improvement on that described and claimed in a' prior patent granted to me October 19, 1920, No. 1,355,998, and is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Fig. 1 is a plan view of my improved gas a mixing device;
Fig. 2 a section on the line 2-2 of Fig. 1; and,
Fig. 3 a view similar to Fig. 2 but showing a slight modification.
n the construction shown in Figs. 1 and 2, my improved gas mixing device comprises a body portion 5 composed of se arate parts 6 and 7, the part 6 being provided with a fuel chamber 8 having an intake port 9 and a discharge nozzle 10. The part 7 istubular in form and provided with'a mixing chamber 11, one end of the part 7 is provided with an enlarged head 12 and the ad jacent end of the part 6 with a similar head 13'having'arms 14 extending in the direction of the head 12 andby means of which the separate heads 12 and 13 are connected by bolts or screws 15 passed through the head 12 and into the arms 14; This construction forms an air space 16 between the separate parts 6 and 7, or between the discharge nozzle 10 of the fuel chamber and the mixing chamber 11.
A tubular member 17 is adjustably mounted- 1n the part 7 of the device and partially forms the mixing chamber 11 of said part 7, clearly shown in Fig. 2 of the drawing and the throat 18 of said mixing chamber flares outwardly asshown at 19 into the air space 16, and said end of the tubular member 17 is provided withan enlarged head 20, in
the periphery of which are spaced apertures 21 adapted to recelve a spanner wrench'or Patented Mar. 28, 1922.
the like to permit of the adjustment of said tubular member in the part 7. p
It will be noted that in Fig. 3 of the drawng, the body portion 5 of the device is made 1n one piece, or the ends 6 and 7 are made integral, and with this exception the remalnder of the device is the same as that shown in Figs. 1' and 2.
It will be noted that in both forms of the construction shown, the discharge nozzles 10 are detachably mounted in the body portion as are also the tubular members 17, and these members are also adjustably mounted in the end or part 7 of the device whereby the position of the throat 18 of the mixing chamber 11 relatively to the nozzle 10 may be regulated so as to control the entrainment of air through said throat into the mixing chamber in the passage of high pressure fuel through said nozzle.
It will be apparent that while I have shown certain details of construction for carrying my invention into effect, I am not necessarily limited to these details, and varlous changes in and modifications of the construction herein shown and described may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages.
Having what I claim as new and desire to secure by Letters Patent, is:-
1. A device of the class described comprising a suitable body portion having a fuel chamber, a mixing chamber and an air fully described my invention,
tably adjustable in the body portion and form-' ber at the other end portion thereof and between which and said fuel chamber is an air space, a fuel discharge device detachably connected with said body portion and in communication with said fuel chamber, a tubular member adjustably mounted in said body portion and extending into the mixing chamber and forming part thereof and provided with a reduced and outwardly flaring throat, the position of which relatively to said fuel discharge device will control the entrainment of air into said mixing chamber through said throat.
3. A device of the class described comprising a suitable body portion having a fuel chamber at one end thereof and a mixing chamber at the other end thereof, said fuel chamber and mixing chamber being joined by an air space, a tubular member adjustably mountedin' the body portion and being provided with an outwardly flaring throat which opens into the'air space and said member being in communication with and formin part of said mixing chamber, and a fue? discharge nozzle detachably mounted inconnection with the first named end of the body portion and extending into said air sp'ace, and a tubular member adjustabliy mounted in the last named end of the b0 y portion and extending into said mixmg chamber and forming part thereof, said 'tu ular member being provided with an outwardly flaring throat which communicwtes with said air space whereby the adj ustment of said tubular member toward and .from said fuel discharge device will control the entrainment of air into the mixing chamber through said throat.
In testimony that I claim the foregoing as my invention have signed my name in presence of the subscribing witnesses this 5th day of January, 1921.
JOSEPH NEEDHAM.
