WITNESSES ATTORNEY y in the following specification,
Patented an. 16, 1932 PATENT OFFICE HAVEN, OI BALTIIOBE, IABYLAND FLUID-111m G DEVICE Application filed April 1, 1930. Serial H0. 440,780.
This invention relates to improvements in devices for mixing or commingling fluids, it being especially an improvement on the mixing device disclosed in the patent to Ci'ocker H. Sanford, 1,328,204 granted January 13, 1920, and it consists of the constructions, combinations and arrangements herein described and claimed.
An object of the invention is to provide a mixing device which embodies as an important part thereof a certain mixing valve by which a jet or stream of gas is ejected into a jet or stream of water in a direction opposite thereto so that the resultingfurious turbulence will produce a most intimate mix ture of the two constituents to the ultimate benefit of a certain fluid-mixing apparatus of Harry Haven, filed April 1, 1930, Serial No. 440,779, with which the instant device'is intended to be used. 4 Other objects and advantages will appear reference being had to the accompanying drawings in which Figure 1 is a vertical section of the imroved fluid-mixing device, parts being shown in elevation.
Figure 2 is a cross section taken on the line 22 of Figure 1 particularly showing how the walls of the mixing chamber act as a stop for the nozzle of the mixing valve, thus insuring the exactly central location of the gas orifice.
Figure 3 is a detail sectional view taken substantially on the line 33 'of Figure 1,
illustrating the approximate paths of the gas and Water through the region of turbulence in the mixing chamber. 1
The mixing device 1, or mixer as it may variably be called, comprises a reservoir 2 and a mixing valve 3 by which water conducted from a source of water by a pipe 4 and gas conducted for a source of carbonic acid gas by a pipe 5 are mixed, the fluid mixture being temporarily stored in the reservoir 2 until an appropriate control (not shown) of a discharge conduit (-3 is opened.
A mixing chamber 7 forms part of and is in communication with the reservoir 2. It is at the water inlet to this chamber that a back check valve casing B is connected, the
ball valve 9 of which it adapted toprevent the retrogression of carbonated water into the pipe system of the soda fountain, dwelling, etc. Where the installation is made.
The mixing valve 3 has a stem 10 with a needle end 11 which is adjustable in reference to the nozzle 12 by virtue of the adjustments of the stem in a gland 13. Contrary to the customary arrangement of needle valves the extremity of the nozzle 12' is closed. The gas orifice 14.- is arranged radially of the bore 15 so as to open laterally of the nozzle or at one side.
This disposition of the orifice has an important bearing on the invention and on the effectiveness of the fluid-mixing apparatus with which the mixing device is intended to be used. It is observed in Figure 1 that the orifice 14 is in direct opposition to the water passage defined by the pipe 4.- and the bore of the valve casing 8. The gas and water jets or streams, both of which are under pressure, will thus oppose each other and produce a furious turbulence in the region of confluence 16 (Fig. 1).
The action will be approximatel as indicated by the tortuous arrows in igure 3.
Gas ejected as designated by the arrows 17 chamber 7 will be diverted as at 20 until the strike the walls of the mixing chamber. deflection of the fluids both at the walls of the mixing chamber and the walls of the nozzle 12 will carrythemaround as designated by arrows 21 so that they will cross the streams designated both b the arrows 19 and 20 as well as themselves efore finally pass ing up the sides and front of the nozzle 12 on the way to the reservoir 2.
It is the combining of the two fluids and the causing of their deflection and crossing as well as recrossing of their mutual paths in the rather constricted space of the mixing chamber 7 that results in that turbulence of the gas and water constituents that will bring about a most intimate mixture. It may be explained that the thorough commingling the apparatus is adapted.
If the mixture were spotty,'that 1s to say so imperfect that a given quantity of the I mixture contained larger volumes of gas in certain regions" than in others, the eliectiveness of the mixture would be greatly minimized for the particular use just mentioned.
'mg chamber, means'for introducing a jet of 'liquid in one direction at one end of the But by driving the. two jets or streams against each other in direct opposition to the y directions of their paths\a tremendous swirlingaction is set up in a very restricted space with the inevitable result of a thorough mixture of the constituents.
The manner in which the orifice 14 is locat ed exactly on. the axial center of the mixing chamber 7 is as follows :--A portion of the nozzle 12 is threaded at 22 to permit itsbe- ,ing screwed into the side of the mixing chamber 7. The internal diameter of the mixing chamber as well as the external diameter of the nozzle 12 will be so a portioned that when the inward screwing o the nozzle 12 is stopped by contact of the lateral corners 23 of the nozzle with the walls of the mixing chamber (Fig. 2) the orifice 14 will stand in the exact osition depicted in Figure 1. The contact 0 the nozzle 12 with the walls'of the mixing chamber thus constitutes a gauge I aaim- 1. A fluid-mixing device comprising a normally closed reservoir having a communicatmg mixing chamber, means for introducing liquid into the chamber in the direction of the reservoir, and means for introducing a jet of gas into the chamberjn the direction opposite to that of the liquid jet, thus td produce a mixture for storage inthe reservoir.
2. A fluid-mixing device comprising a mixchamber, and a mixing valve having a nozzle fitted in one side of the chamber with a radial orifice axially alined with the chamber and so opening as todischarge a jet of gas into the chamber in opposition to the liquid jet.
I 3. A fluid-mixing device comprising a mixmg valve having a nozzle with a radial orifice opening at one side of the nozzle to discharged jet of gas in one direction, a mixing chamber into the side of which the nozzle is projected uiltil the corners ofthe nozzle engage adjacent portions of the wall of the 'chambertlius establishing the orifice in line with the axis of themixing chamber, and
means for introducing liquid into the chamber in the direction opposite to that of the gas jet and producing a region of confluence between the nozzle and said liquid inlet means.

1 to the position of the orifice 14. In addition the mixing chamber,
to this the engagement of the nozzle with the walls of the mixing chamber tendsto stabilize the mixing. valve. The free end of the nozzle is thus supported by the walls of and the rather high fluid pressure to which it is subjected W111 have little efiect on tending to loosen the mixing valve.
i The operation is as follows :It is to be understood that the mixing device -+used in conjunction with the fluid-mixing apparatus of the application previously mentioned. This, however, is not to b'eregarded willbe as a res'trictionbecause the instant mixing device might be used in other connections.
Upon opening the control device- (not shown) which will be associated with the discharge conduit 6, the resulting-flow of fluid will be accompanied by aninflow of water at the pipe 4. The same opening of the con- .trol device causes an inflow of gas at the pipe 5. The two fluids mix in-the region 16 (Fig. 1) in----the manner already fully explained (Fig. 3) so that the reservoir 2 is temporarily stopped with the mixture prior to its discharge at the pipe 4. v
While the construction and arrangement of the improved fluid mixing device is that of a generally preferred form, obviously modifications and changes may be made with out departing from the spirit otthe invention or the scope of the claims.
