Specification of Letters Patent.

Patented heb. 5, 191.

Application :tiled May E5, 1913. aerial No. 765,540.

To all whom 'it may concern.'

Be it known that I, ARTHUR E. DURAM, a citizen of the United States, residing at Chicago, in the county of Cook and State of llllinois, have invented certain new and useful Improvements in Liquid-Separators and the like, of which the following is a description.

My invention relates to means for removing air or gas from water or other liquid.

The object of my invention is to provide a simple, reliable and highly e'licient device of the kind described, wherein a substantially complete separation is secured between water, or otherliquid and air or gas.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the accompanying drawings, wherein like or similar reference characters indicate like or corresponding parts:

Figure 1 is a verticallongitudinal section of one form of my device.

Fig. 2 is a similar view of a slightly modied form.

Fig. 3 is an elevation of still another form of my device with parts removed and broken away to more clearly show theconstruction of my device.

In the form shown in Fig. l of the drawings, l is a commingler having a steam inlet 2, and a water inlet so arranged that the water entering the commingler will fill the chamber 4 and escape into the central steam passage 5 through the several orifices 6 6 thus condensing the steam passing into the commingler and at the -same time raising the temperature of the water which issues from the outlet opening 7. When thus arranged it is well known that more or less air or gas is entrained in the steam, and water entering the commingler through the inlet pipes 2 and 3 will be discharged therefrom with the hot water. It is the purpose of my present invention to provide a simple and ecient meansy for eliminating the air or gas from the water so that the water may be satisfactorily employed for heating or other purposes. y

In the form shown in Fig.` 1 my device consists of a reservoir 8 of ample capacity and a receptacle 9 positioned within the reservoir. The reservoir 8' may be provided with a loose cover 10 to prevent dust and other foreign matter from entering the reservoir, a suitable opening or vent 11 being provided to prevent the free escape of air or gas. rllhe receptacle 9 is rigidly secured in position within the reservoir and is preferably open at its upper end.v The upper edge of the receptacle is positioned slightly form shown, a plurality of legs or braces 12-12 are rigidly secured to the walls of the receptacle and extend to the walls of the reservoir to which they are also rigidly attached thereby preventing any movement between the receptacle and reservoir and maintaining a broad open passageway between their walls and bottom surfaces. rllhe commingler 1 is preferably provided with a flange 14 or other convenient means f or rigidly attaching it to the cover 10 to maintain the relation between the several parts of the device. An outlet pipe 15 is also provided attached in any suitable manner to the bottom of the reservoir 8 so that liquid entering my device will be discharged into the receptacle 9 whence, it passes upward and over the edge of the receptacle into the reservoir 8 thence it flows slowly downward to the bottom of the reservoir and out through the pipe 15. A suitable valve 16 is preferably provided in the Water inlet pipe 3 of the commingler to control the admission of liquid and to maintain the desired height of water in the reservoir. vious that when thus constructed a mixture :0f water and air or gas discharged into the receptacle will first rise comparatively rapidly to the top of the receptacle where it will lose substantially all of its velocity and pass slowly in a broad shallow stream over the top of the receptacle where any air or gas entrained in the water is brought-t0 the surface and escapes, the liquid passing It is obslowly downward to theoutlet pipe substani tially free from all air or gas.

ln all cases however, ll arrange-to reduce the velocity of the duid escaping from the' receptacle to the lowest possible point and bring the liquid as it passes out of the receptacle, into as lintimate contact as possible .with the free air, and this is accomplished preferably by maintaining the water level in the reservoir substantially at the upper 'edge of the receptacle 9.

l .In the form shown in Fig. 2 the reservoir 8 and receptacle 9 are arranged substantially as hereinbefore described, except that instead of the commingler extending downward into the receptacle an inlet pipe 20 'is provided extending through the wall of the reservoir-and into the side ofthe receptacle. In this form the liquid entering the receptacle will have no downward tendency but will lose its velocity as it passes over the wall of the receptacle substantially as hereinbefore described.

If desired suitable automatic mechanism may be provided for controlling the height of the fluid in the reservoir. In the form shown an arm 22 is pivotally attached to the wall of the reservoir 23. A float 24 is attached to the free end of the arm. A lever 25 is also attached to the reservo-ir as by the bracket 26, one end of the lever 25 is connected by a link 27 to the arm 22 so that movement of loat 24 will produce a corresponding movement in the lever 25' the opposite end of the lever 25 is connected by a to mamtain in the casing. A shelf 39 is preferably arranged across the casing at the upper edge of the partition. In this form a suitable valve 40 is provided in the inlet pipe 36 having an arm 41 connected to the free end of the arm 43 of a bell-crank 43-44 having its axis extending through a suitable fluid -tight bearing in the wall of the casing '35. The arm 44 of the bell-crank is within the casing and is connected by a rod 45 to the arm 46 of a bell-crank 46-47 mounted within the casing and having a float 48 attached to the free end of the arm 47 of the 1bell-crank. The several parts are so arranged that the movement of the float 48 will control the valve 40 to maintain the desired Water level in the shell. A suitable air valve 50 is provided above the water level so that any accumulation of air within the shell may be discharged when desired, or if preferred the valve 50 may be suitabl connected to the float 48 or if preferred le t slightly open to allow a constant leakage sufficient to prevent air locking in the device.

Having thus described my improvement it is obvious that various immaterial modiications may be made in my device without departing from the spirit of my invention, hence I do not wish to be understood as limiting myself to the exact form or construction shown.

y What I claim as new and desire ,to secure by Letters Patent is:

1. In a device of the kind described, a reservoir having an outlet, in combination with a rece tacle positioned within said reservoir an arranged to receive all liquid passing therethrough, means for directing the fluld toward a side wall of said receptacle, the walls ofsaid receptacle extending upward into close proximity to the surface of the liquid in said reservoir and adapted to force all liquid passing throu h said reservoir to the surface of the liqui in the reservoir, the several parts being so proportioned that the liquid will lose the greater part of its velocity before it escapes from said receptacle.

2. In a device of the kind described a reservoir having an outlet and a receptacle open at the top positioned in said reservoir and rigidly attached to the walls thereof, the top of said receptacle being substantially at the level of the liquid in said reservoir, in combination with means for directing a fluid into said receptacle against one wall thereof, the several parts bein soproportioned that the liquid entering sald receptacle will lose the greater part of its velocity before it escapes from said receptacle.

In testimony whereof, I have hereunto signed my name in the presence of two sub? s'cribing witnesses.
