To all whom it maycouccrn:

Be itknown thatI, WILLIAM JAMES BAKER, a subject of the Queen of Great Britain, residing at Scarborough, England, have in vented new and useful Improvements in or Connected with Apparatus for Separating Water and Oil or Grease from Steam, of which the following is a specification. l

My invention relates to improvements in or connected with separators for removing oil or grease and water from steam, which separators are combined with a special form of pump for drawing away the separated water and oil and a settling-tank for facilitating the recovery of the separated oil.

To enable my invention to be fully understood, I will describe it by reference to the accompanying drawings, in which- Figure 1 represents a sectional elevation of my improved separator, pump, and scttlingtank. Fig. 2 is a sectional plan of the separator, the section being taken on the line co m, Fig. 1. Fig. 3 is a sectional plan of the pump, the section being taken on the line 2 2, Fig. 1. Fig. l represents a sectional elevation, and Fig. 5 a plan, of a. modified form of separator, the cover being removed in the latter figure; and Fig. (3 illustrates the improved separator connected with a close receiver instead of with a pump.

Similar letters of reference indicate the same or similar parts in all the drawings.

Referring first to Figs. 1 to 3, a is the shell of the grease-separator, and b is the inlet branch pipe thereof, the said inlet-pipe being adapted to be connected to the exhaust-pipe conveying the steam from which the grease istobe removed. Immediately upon enterin}; thesefiarator the steam expands and is conducted by the deflector c to the surface of the water d, which occupies the well or bottom portion of the separator a, and upon the" surface of which water all greasy spray is attracted and collected. The steam then takes a turn in an upward direction, as indicated by the arrows, Fig. 1, and is caused to pass through the spaces left between several rows of vertically-arranged angle-iron bafiiers e, upon the inner or channel-like surfaces of which the steam impinges and leaves the whole of the remainder of the grease it contains, which grease, mixed with a small porpheric pressure.

After passing the rows of angle-iron baiilers the The grease, as it colpurified steam passes outof the separator by f the outlet branch 9. As these separators are generally connected with the condenser ofa steam-engine, it follows that a vacuum constantly exists in the separator, owing to which vacuum the grease and water accumulating in the well would not fiowaway against atmos- A; small pump is therefore necessary, which operates in a close receiver it, connected with the separator by the overflowpipe f and by the air-pipe t', which latter equalizes the vacuum in the separator and At thebottom eitheclosere ceiver h isthe pump-barrel j, having sper tures formed in its sides through which the greasy water from the receiver flows, being forced down past-the valve k, whichafter each downward stroke isforced up into its seat by a spiral spring. The pump-ram l is actuated by means of a short connecting-rod m and the crank it upon the shaft 0, which passes through a stuffing-box at the side of the receiver h and is driven by the pulley p, carrying a belt driven from the nearest shafting or by an clectromotor.

tank (1 through the pipe 1', and in this tankthe separated oil rises to the surface and is at times drawn 0d at the bib'cock s, the water constantly passing away from the bottom of the tank and overflowing at the outlet-pipe t.

In the separator represented in Figs. 4 and 5 the outer shell a, inlet branch b, and outlet branch g, and overflow-pipe f are similar The grease and water from the pump pass into the settlingto those shownin Figs. 1 and 2 and hereinhefore described; but in this arrangement when the greasy steam has entered the separator by the inlet branch b it immediately expands in the chamber a, fixed within the shell a, and deposits a large portion of grease therein, which grease and separated water, as well as the steam, pass down the pipes at a", the steam impinging upon the surface of the water in the well or lower part of the separator, whereby further portions of grease are attracted and separated. Finally the steam passes between parallel plates e .e, fixed across the separator, as shown,from whichwroject alternate bafilers e e, placed anat angle to the plates. In the recesses thus formed the remainder of the oil contained in the steam is deposited with greasy water, which gravitates to the well of the separator and is drawn 01?, as before described. The purified steam passes out at the branch g. Instead of the pump previously referred to for drawing oif the collected oil and water from the oil-separator an air-tight receiver may be employed of the kind represented at Fig. 6 and which is placed below the level of the separator.

The top of this receiver 11. is connected to the upper part of the separator by the air-pipe t' and through the overflow-pipe f. The oiland water as they are condensed flow into the receiver u, the vaccum in the said receiver being equalized to that existing in the separator by means of the air-pipe i. A water-gage o is provided'to show when the receiver is full.

To empty the receiver a the valves of the overflow-pipe f and the, air-pipe t are both closed, the vent-cock w is opened, andthe greasy water and oil are then drawn 0E thrown the cock as.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed,

I I declare that what I claim is 1. In apparatus for separating oil and grease from steam, the combination of a casing or shell having a steam-inlet and a water-well,
