MIXING DEVICE FOR OILGAS APPARATUS.
vApplication filed November 12, 1925. Serial No. 68,543.
My invent-ion relatesto mixing devices for use in oil-gas apparatus and designedto introduce air and oil into a mixing tubey before their introduction into the vaporizing and lixing chambers ot' an oil-gas apparatus such as is shown and described in my pending application for United States Letters Patent, Se-
rial No. 707,071, filed Muy si, 1924. l The object of my invention is to provide a device of the above-described character which is simple in its construction and efficient in its operation and which will permit of ready access to its interior for the purpose of igniting the mixture in the tube.
The said invention consists of means hereinafter fully described and particularly set forth in the claims.
In the annexed drawing:
Figure 1 represents an axial cross-section 2010i a fragmentary portion of a mixing device embodying my invention;
Fig. 2 represents a section taken upon theplane indicated by lines II-*II in Fig. 1.
In the illustrated embodiment of my invention, the mixing pipe l has a. portion 2 which forms a slideway for a Venturi-tube 3. This Venturi-tube 3, as plainly shown in Figure 1, is
formed with a bore whose wall converges to- Ward the entry end of the mixing pipe 1, but
whose smallest cross-sectional area is disposed p somewhat short of the extreme entry end, this wall diverging from the most restricted 'ortionof the bore to the extreme entry end o the mixing pipe 1 so as at said extreme entry end to be substantially the same cross-sectional area as' the pipe 1. The Venturi-tube 3 is provided with a rack 4 which projects `into a groove 4 formed in the part 2. This rack is engaged by a pinion 5 fixed to a small shaft 6 suitabl mounted and provided with the handle 7 I3 turning the latter, the v-enturi may be moved7 and hence adjusted axially inthe tube part 2.
The mixing tube is connected with the air pipe 8, the latter discharging into the enlarged l entry end of the mixing pipe 1, and projecting through this pipe 8 coaxially with said tube- 'part 2 is a fixed conical-ended oil nozzle 9 con` trolled by a needle valve member 10 opera-ble bynreansi'ofa handle 11. The oil nozzle com- 1tl1 a duct 12 leading to a suitable ture 13 which registers with a threaded aperture 14 vin `the wall of the tube-part 2, which latter aperture is, however, of considera-bly greater diameter than aperture l,` as shown.
It will be seen from the above-described construction that the Venturi-tube may be adjusted relatively to the conical end of the oil nozzle and the area of the .air passage between them varied so as to vary andl hence adj ust the amount ot' air admittedinto the mixing tube.
When it is desiredto ignite the mixture in the tube, the plug 15 is removed, thereby afi fording access to such mixture and permitting it to be ignited through the registering apertures 13 and 14.
Aperture 14: being of considerably greater diameter than aperture 13, aconsiderable range of adjustment of the Venturi-tube is secured without destroying the registration of such apertures.
What I claim is Y 1. In a mixing device for oilas apparatus,
the combination of a mixing tu ie; a Venturitube mounted therein, Said Venturi-tube; being formed with a rack portion; a cooperating gear engaging said rack and means for driving said gear so as to adjust said Venturi-tube in said mixing tube; an air pipe opening into ,the small end of said Venturi-tube; a valvetube mounted therein; 'means for longitudinally adjust-ing said Venturi-tube an air pipe openingintosaid Venturi-tube; a' valve-controlled oil nozzle extending into said Venturitube within said air pipe, said mixing` and Venturi-tubes being provided with registering apertures; and a closure for the aperture in the mixing tube, said latter aperture being of larger diameter' than the registering aperture of said Venturi-tube.
Signedby me -this 31st day of October, 1925.
