FLUID MIXING DEV|CE. APPLICATION FILED MAY3I, 1919.

' Application filed May 31,
To all whom it may concern:
Be it known that 1, WILLIAM W. CUM- MINGS, a citizen of the United States, residing at Woburn, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Fluid- Mixing Devices, of'which the following is a specification.
This invention relates to a device for mixing gases or fluids and at the same time raising them to a considerable pressure.
The object of the invention is to 'prov vide a simple and inexpensive device where- -by different gases or fluids may be raised to any desired pressure and at the same time be mixed in such a manner as to produce relative fixed proportions but varying quantities of output of the said gases or fluids, and in accomplishing this result advantage is taken of the varying specific ravities of the fluids or gases handled and applying thereto varying centrifugal forces whereby certain fixed proportions of the gases may be obtained which will not vary with the quantity of output of the device.
'To attain these objects I utilize a plurality of rotary fans driven by power inde pendent of the pressure of the gases to be mixed, the total areas of the blades of the fans differing one from the other the quantities of gas and air being determined by the widths of the blades and the pressure obtained being determined by the diameter of the fans and the number of rotations per minute, the relative diameters of the fans being reversely proportioned to the specific gravity of the gases.
Heretofore gases or gases and air have been mixed in proportions to produce a nonexplosive mixture and delivered at the point where suilicient auxiliary air or gas has been needed for complete combustion, and such additional gas has there been inducted by means of some form of inspirator, these devices relying upon the action of the inspirator for the proper but varying quantities of additional gas, according to the rate at which the machine is run. Also gases have been mixed in an explosive ratio and carried for distances in a pipe under such conditions that an explosion is liable to occur throughout the whole length of the P ft is believed however that heretofore gases have not been mixed by centrifugal Specification of Letters Patent. Patented J 11119 27, 1922.
1919. Serial No. 300,933.
means whereby certain fixed proportions may be held constant and the volume of mixedgases varied at will.
The invention consists in a rotary fan blower such as hereinafter described and particularly set forth in the claims.
Referring to thedrawings:
A lFlgure 1 is a sectional elevation of my improved gas mixing device.
Fig. 2 is a sectional elevation taken on l 1ne2-2 of Fig. 1. r v
Fig. 3 is a sectional elevation similar to F1g. showing a modified form of my inventlon. v
Like numerals refer to like parts throughout the several views of-the drawings.
In the drawings, referring to Figs. 1 and 2,5 is a, casing provided with two chambers 6 and 7, the chamber 6 having an inlet openmg and the chamber 7 having an inlet opening 9, both of said chambers opening lnto a common outlet 10, and said chambers bemg separated one from the other by a partition 19.
A fan 11 is located in the chamber 6 and the fan 12 in the chamber 7 The fan 11 is provided with blades 13 and the fan 12 is provided with blades 14;. The blades 13 are substantially longer than the blades 14.
Both of the fans are fastened to a rotary shaft 15 which is rotatably mounted in bearings 16 on standards 17 forming a part of the frame 18, said shaft being rotated by means independent of said gases such as a pulley fast to said shaft but not shown in the drawing. 7
The operation of the device is as follows: The inlet opening 8 is connected by a pipe 8' to a source of gas supply and the inlet opemng 9 opens into the air. Upon rotation of the shaft 15 the two fans 11 and 12 are rotated and a certain portion of gas and of air are drawn in through the openings 9 and 8, respectively, and mixed together and delivered at the outlet 10. The proportion of gas to air will always remain the same, in-
dependent of the speed of rotation of the opening 38. Both of said fans are fastened to a shaft 39 which is rotatably mounted in bearings 40 on a frame 41 and is rotated by a pulley not shown in the drawings. The casing 33 opens into a branch outlet opening 42 and the casing 34 opens into a branch outlet opening 43, these two outlet openings forming a part of one outlet opening 44, so that the casings 33 and 34 both open into the same outlet opening 44.
The operation of this device is the same as the other device of my invention hereinbefore described. The gas is drawn in through the opening 38 by the fan 36 and air is drawn in through the opening, 37 by the rotation of the fan 35. Both of the fans are rotated by the shaft 39, to which they are fastened, and the gas and air mixed at the outlet opening 44 in certain fixed proportions, as determined by the width or the blade of the fan and the volume of the mixed gases is dependent upon the rotary speed of the shaft 39.
Having thus described my invention what I claim and desire to secure by Letters Patent is:
1. A blower for mixing gases and supplying pressure thereto having, in combination,
a casing provided with two chambers, with an inlet for each of said chambers and a common outlet for said chambers, a fan in each of said chambers, the length of the blades of one of said fans being difierent from the length of the blades of the other of said fans and means independent of the pressure of said gases for rotating said fans.
2. A blower for mixing gases and supplying pressure thereto having, in combination, a casing provided with two chambers, with an inlet for each of said chambers and a common outlet for said chambers, a fan in each of said chambers, the length and width of the blades on one of said fans being different from the length and width of the blades on the other of said fans, and means independent of the pressure of said gases for rotating said fans.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses. I
