FRANK S. STRITE, OF DALLAS, TEXAS.

DE-AERATOR.

' Specification of Letters Patent.

Patented Sept. 9, 1913.

Application filed January 10, 1913. Serial N 0. 741,288.

To all whom it may concern:

Be it known that I, FRANK S. STRITE, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in De-Aerators, of which the following is a specification, reference being had to the accompanying drawings.

This invention comprehends certain new and useful improvements in water de-aerators, and has for its primary object to. provide a device which will thoroughly separate the air from the water.

It isa well known fact that air and gases mix with water as it is drawn from the ground and exposed to the atmosphere.

When the water is to be employed in the manufacture of ice and for other purposes, the air and gases should be separated therefrom, and for this purpose I have constructed a deaerato'r of novel form and which will be highly eflicient and elfective in the performance of its duty.

My invention consists in providing a tank with a perforated cylinder therein, means for forcing the water into the, tank and spraying the same against-the cylinder to cause the air and gases to separate from the water, and means for causing a vacuum in the upper end of the tank from which a suction pipe extends to allow ready escape of the separated air and gases.

The construction, combination, formation and arrangement of the parts of the deaerator will be hereinafter more fully described, claimed, and particularly pointed out in the accompanying drawings, in which Figure 1 is a diagrammatic view of my device. Fig. 2 is a vertical longitudinal section throu h the tank and perforated cylinder, cleafiy showing the parts thereof.

Referring more particularly to the drawings, in which similar reference characters designate corresponding parts throughout the several views, the numeral 1 designatesthe tank having the removable lower portion 2 carrying the supportlng legs 3, and secured along 1ts upper edge to the lower edge of the tank 1 by the rivets 4:, or other suitable means. The removable lower portion 2 carries the inwardly directed inner flange 5 near its upper edge, upon which flange 5 rests the lower edge of the perforated cylinder 6, which may be formed of a wire mesh, or other foraminous material. The removable lower section 2 forms a chamber for the de-aerated or purified water, and has a drain opening 7 in the bottom thereof with the plug 8 removably secured therein. The outlet pipe 9 has one end secured in the side of the removable lower portion 2, by means of which the water may be withdrawn from the section or chamber 2. The upper edge of the cylinder 6 is spaced some distance from the upper end of the tank 1 and said tank is pro-- vided in the side thereof adjacent the upper end w1tl1 an opening 10 through which the supply pipe 11 is secured, suitable bushing 12 being placed around the pipe 11 at the point at which it enters the cylinder to form a water and air-tight connection. The outer end of the supply pipe 11 is connected with the centrifugal pump 13 which is operated by the motor 14:, or any other suitable means to force the water to be purified into the tank 1, by means of the pipe 11, under pressure, as will be clearly understood.

The inner end of the pipe 11, within the tank 1, is turned downwardly, as shown at 15, within the cylinder 6, the lower ex; tremity of the pipe 15 terminating slightly above the lower end of the cylinder. The pipe 15 is provided with the radially di rected arms 16 within the cylinder 6, said arms 16 being shown as arranged in pairs, although any number of arms may be provided. The arms 16 are provided with caps 17 upon their outer ends and the small perforations 18 in thesides thereof, and extend ing the entire length of said arms.

The upper end of the tank 1 is provided with the outwardly directed flange 19, upon which is secured the flange edge 20 of the removable top 21, by means of the bolts 22, or the like. Secured in the removable top 21 is one end of an air suction pipe 23, the

opposite end of which connects with a vacuum pump 24, operated by the motor 25, or other suitable power. The suction pump 24- creates a vacuum in the upper end of the tank 1 and draws the air and gases from the tank 1 as said air and gases separate from the water forced out of the small perforations 18 in the arms 16, the water finding its way to the lower removable section or chamber 2, as will be clearly apparent. By means of the construction described above, and clearly shown in the drawings, it will be apparent that the impure watercontaining air and gases, will be forced through the pipe 11 and through the small perforations 18 of the arms 16 projecting from said pipe 11, under high pressure, causing the water with the air and gases to be forced out of the arms 16 and against the cylinder 6, in the form of a fine spray, thus causing the air and gases to separate from the water. The separated air and gases will be readily drawn out of the upper end of the tank 1 by way of the air suction pipe 23 while the small globules of water will find their way to the removable section or chamber 2 from which the same may be withdrawn by means of the outlet pipe 9. The removable section or chamber 2 may be readily drained when occasion may require by removing the plug 8.

It will be understood that while I have shown the preferred form of my invention, minor changes in the details of construction may be made, and any form of centrifugal pump, or other means may be employed for forcing the Water through the pipe 11 and the arms 16 thereof, and any construction of vacuum pump, or other means may be employed for drawing the air and gases from the tank 1.

It will be understood that as the perforations 18 in the arm 16 are very small and the impure water is forced through these openings under high pressure, the water will be separated into extremely small or minute particles before coming in contact with the perforated cylinder 6, thus freeing the air and gases from the water and allowing ready escape of said air and gases, as previously described.

What is claimed is l. A device of the class described comprising a supply pipe having radially directed arms, said arms being closed at their free ends and having perforations extending longitudinally thereof, a perforated cylinder surrounding the "arms, a tank inclosing the arms and cylinder, means for forcing water through the pipe and out of the perforations of the arms under pressure to cause air and gases to separate from the water, a water chamber at the bottom of the tank, and

ing into the tank above the cylinder, the I inner end of the pipe being directed downwardly, radially extending arms carried by the inner end ofthe pipe within the cylinder, said arms being provided along their sides with small perforations, means for closing the outer ends of the arms, means for forcing water containing air and gases through the supply pipe and out of the perforations of the arms of said pipe .to cause the air and gases to separate from the water, and means for withdrawing the air and gases from the tank.

3. A device of the class described, comprising a tank, a cylinder Within the tank, the lower end of the tank being removable and forming a water chamber, means carried by the removable lower end of the tank for supporting thecylinder, a supply pipe depending within the cylinder, the upper end of the cylinder being spaced from the upper end of the tank, the supply pipe entering the chamber above the cylinder, rearwardly extending arms carried by the lower end of the pipe and provided with perforations in opposite sides, means for forcing water throu h the pipe and within the perforations in t e arms and against the cylinder to cause air and gases to separate from the water, the latter finding its Way to the water. chamber, an outlet pipe projecting from the water chamber, and means removably connected with the upper end of the tank for withdrawing the separated air and gases.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.

FRANK S. STRITE.
