DAVID M. STOTT, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF TO HORACE E. ARGO, OF

CHICAGO, ILLINOIS.

EQUALIZER AND SEPARATOR FOR STEAM.

To all whom it may concern:

Be it known that I, DAvro M. STOTT, a citizen of the United States, residing at Chicago in the county of Cook and State of Illinois, have invented a new and useful Equalizer and Separator for Steam, of which the following is a specification.

The objects of my invention are 1st. To hold back the rushing of the water with the steam out of a steam boiler, which occurs frequently, leaving the boiler empty and allowing it to become super-heated while at the same time there is no steam pressure, as shown by the safety valve. Then when the water returns and comes in contact with the super-heated boil er, it vaporizes so rapidly that the safety valve is unable to take care of it and the result is an explosion.

2nd. To separate the water from the steam before it reaches the main nozzle connecting to the heating system, engine, pump or other device using steam.

3rd. To form a safety device so that if a rush of water should take place it would be stopped until the water level was equalized in the boiler, and at the same time forcing the steam pressure back into the boiler where it would be relieved by the safety valve if too great.

4th. To act as a blow-off to remove any oil that may have collected in the boiler, which collecting on the to of same is so detrimental to the making of steam and the proper working of the boiler.

This device may be applied either inside, or outside of a boiler, and I do not confine myself to the particular form or arrangement shown in making my claim as it is obvious that this might be modified or changed and still not depart from the spirit of the invention which is when, for any reason the water is inclined to flow out of the boiler with the steam to check the passing of either water or steam fromthe boiler until an equilibrium is maintained and the water level established.

I attain these objects by the device illustrated in the accompanying drawings of which Figure 1 shows a side elevation in connection with the ordinary water column and steam gage of a steam boiler with parts broken away to show construction. Fig. 2 is a cross section taken on the line 2-2 Fig. 1. Fig. 3 is a similar view showing the baflie plate lifted up against the cover.

Specification of Letters Patent.

Application filed April 30, 1908.

Patented Oct. 27, 1908.

Serial No. 430,056.

Similar letters refer to the same parts in the several figures.

Let A represent the main body of the device with a flanged opening a at the bottom connected to the supply pipe from the boiler a The body A has a flange a around the top, bolted to which is the cover A having in its center a flanged opening a for connecting with the pipe for conducting the steam' wherever it is to do its work.

It will be noticed the cover has a portion of its width A depressed throughout its length for a purpose to be explained later on.

Inside of the chamber A is a baffle plate B which divides the chamber into two parts 1 and 2. This plate rests upon flanges or studs 6 which are formed on the inside walls of the chamber A, along its length, integrally with the side walls. The plate B has openings b b for steam to pass into the chamber 1, so arranged as to direct the steam toward the center of the de ressed portion of the cover, along its lengt 1. The effect of this is to de fleet the steam from its course up through opening a allowing any of the water of condensation to fall on the plate B. This plate is formed as a pan to catch this drip and allow it to pass out through one small opening. The end walls of the pan 6" are shaped to fit the depressed portion of the cover at its ends when the late is raised up as shown in Fig.

3. The sides of the plate are arched along its length forming domes cc from which the openings 12 6 lead.

The opening 12 is suflicient to take care of the little water of condensation which may accumulate in the pan but not suflicient to permit any great volume of water which might rush up with the steam and if not prevented would be forced into the pipes be yond. When such an action occurs the water, coming in contact with the broad surface of the baffle plate B willraise it off the flanges b-b into the position shown in Fig. 3, bringing the holes I) 5 against the curve of the sunken portion of the cover A closing them completely allowing neither water nor steam to pass further.

After the flow is stopped and the ressure directed back into the boiler to be taken care of by the safety valve, the natural tendency of waterto seek its level would pause it to flow back into the boiler, either by the pipe D connected with the water column D or through the supply pipe a After the water commenced to return in this way the small opening I) in the bottom of plate B would relieve any tendency to form a vacuum in the pipes beyond. The plate B would return to its normal position allowing the steam to pass up the supply pi e through a The usual steam gage D is s own over the top of the water column.

Between the chamber A and the water column D in the ipe D is a valve D which when there is oi on the water in the boiler can be opened to draw ofl the same without emptying the boiler.

Having thus described my invention,- what I desire to claim and have granted by Letters Patent is- 1. In a steam separator and water equalizer, a casing provided with inlet and outlet passages, and a bafiie plate interposed between said passages in position to be moved by the inrush of water and provided withan opening adapted to be closed by the movement of the bafile plate, due to the inrush of water, and provided with a port suitably positioned to remain open during all movements of the baffle plate, substantially as described.

2. In a steam separator and water equal izer, the combination of a casing rovided with inlet and outlet passages, ant a baflie plate interposed between said passages and positioned to be lifted by the inrush of water, and provided, near its periphery, with a hole adapted to be closed by the lifting of the baffle plate, and provided, near its center, with a port adapted to remain open during all movements of the baffle plate, substantially as described.

3. In a steam separator and water eq ualizer, the combination of'a easing rovlded with inlet and outlet passages, anc a baffle plate interposed between said passages and adapted to be lifted by the inrush of water, and provided, near its periphery, with a hole adapted to be closed by engagement of the I baffle plate with the wall of the casing when the baflie plate is lifted, and provided with a port adapted to remain open during all movements of the baffle plate, substantially as described.

4. In a steam separator and water equalizer, the combination of a casing provided with inlet and outlet passages, a baffle plate interposed between said passages, and provided, around its periphery, with a backwardly turned edge, and provided, near said edge, with a hole adapted to be closed by engagement of the baffle plate with the wall of the casing when the plate is raised, and provided, near its center, with a port adapted to remain open during all movements of the baflie late, substantially as described.

5. n a steam separator and water equalizer, the combination of a casing provided with inlet and outlet passages, the wall of the casing adjacent the outlet passage being inwardly dished to provide a boss, and a bafiie plate recessed in its center and provided on its edge with a pair of baekwardly turned lips or flanges, and having, near its edges, a pair of holes adapted to be closed by engagement of the baffle plate with the boss around the discharge passage, the baffle plate being further provided, near its center, with a hole adapted to remain open during all move ments of the baffle plate, substantially as described.

6. In a steam separator and water eq ualizer, the combination of a casing provlded with inlet and outlet passages, and a baffle plate of recessed construction, provided with a port for the passage of steam and theoutflow of water of condensation, said baflie plate being adapted to be moved by the inrush of water, substantially as described.
