SPECIFICATION forming part of Letters Patent No. 587,560, dated August 3, 1897.

Application I'iled April 13, 1 8 9 7.

To all whom, it may concern:

Be it known that l, GEORGE I. ROBERTS, of

v New Rochelle, county of Vestchester, and

State of New York, have invented a new and useful Improvement in Steam or Tater Traps or Separators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the figures marked on the accompanying drawings, which form a part of this specification.

Figure l isa central Vertical section, showing parts in elevation ,of an apparatus to which I have applied my improvements. Fig. 2 is a transverse section of the same, looking toward wall 8. Fig. 3 is a transverse section of the same, looking toward wall 10. Fig. 4 is a detail view of one of the bafiie devices. Fig. 5 is a detail section of a modification hereinafter referred to.

My invent-ion relates to steam or water traps or separators.

More particularly stated, my invention has for its object the separation of grease, oil, or other impurities from the steam or water house-heating and power plants.

The improvements consist in the following construction and combination of parts, the details of which will iirst be fully described and the features of novelty then set forth in the claims. In the drawings, l represents the main shell of the trap or separator, which may be made in any suitable shape or of any suitable material. In this instance I have shown it of cylindrical form.

2 is the upper or steam compartment, and

i 3 the lower or water compartment. Both compartments are divided by a central perforated plate 4, permitting communication between them.

5 and 6 are partitions or walls which separate or isolate the upper or steam compartment from the other compartments of the separator. These walls are inclined, as shown,

and are secured at either end of the perforated plate 4 and to the opposite heads of the separator by suitable fastenings; but itis obserin No. 631,988. (No man.)

vious that their shape and disposition may be modified. p

The lower main compartment 3 has, preferably at one side, a secondary compartment 7 for grease, oil, or other extraneous matter, and 8 is a division-wall between the compartments 3 and 7, the upper edge of which constitutes an overflow for the contents of the compartment 3 and which edge determines the height of the fluid-level in said compartment.

Preferably at the opposite side of the main lower compartment 3 is another compartment 9 for the purified water received from compartment S. 10 is the division-wall between these latter compartments, which wall is provided with a series of perforations lvl, disposed below the fluid-level l2 of compartment 3. Y

In practice they extend from or near the bottom up into the neighborhood of the central vertical deptlrof the compartment 3.

13 is a wastepipe leading from compartment 7, and 14 a waste-pipe leading from compartment 3, for the discharge of any sediment accumulating therein, and these pipes may be, if desired, connected together.

l5 represents a discharge-pipe from the oil or grease collecting chamber 7, and preferably enters that compartment near the middle of the same or at any desired intermediate point.

1G is the discharge-pipe leading from the clear-water compartment, 9. I may provide compartment D with a water-gage 17 and the compartment 7 with a similar gage 18 to show the height of the grease or oil therein.

19 is the inlet-pipe for the conveyance tov the drawings I have shown these baule-plate frames of semicircular shape to conform to the particular form of separator herein shown.

, separator in this particular instance I contemlss plate connecting inlet-port 2O with the eX- haust from a steam-engine and the outlet-port 2l to the outgoing pipes to a steam-heating system, or said port may be connected with an exhaust direct or any exhaust indirectly connected with a steam-heating system.

24 is a pump governor or starter device, which need not be particularly here described. This device serves to start and govern the ae-V tion of the pump which I prefer to connect with the clear-water pipe 16, which pipe is designed to Jfeed a boiler. The governor device 24: may, however, be dispensed with and the pipe 16 may be connected in any other way.

In the particular use of my separator, as above described, the pipe 19 is connected with the house-returns pipe of the heating system. This pipe 19 extends inwardly and discharges into the compartment 3, and all grease and other impurities are intercepted at this point.

In the modification shown in Fig. 5 the pipe 19 is substituted by an inclined channel 25, formed by the partition 5 and the partition 26, whereby the house returns may be discharged into the compartment 3.

I prefer to provide thehead 27 of the separator with a ange and bolts, whereby aocess to the'interior of the separator may be had for the purpose of renewal, repair, or the like.

The impuritities in the steam entering the port 20 are interrupted by the baffle device and precipitated, together with the accumulated moisture, through the perforations in the plate 4 into the compartment 3. In like manner the impurities from' the house-returns pipe are discharged through the pipe 19 into the compartment 3. All the grease and other impurities which are lighter than Water accumulate at the surface at the water-level in this compartment and overflow the top of the division-wall Sinto the oil or grease compartment 7 where they are drawn off, as desired, throughthe pipe l5. The clear or separated water passes through the perforations ll below the water-level into the clear-water compartment 9, from whence they-are pumped back through the feeding system into the boiler.

In Fig. 4 is shown one of the baffle-frames having a series of ropes suspended therein, while the battle-plate frames shown in Figs. l, 2, and 3 are provided with a series of suspended chains. v

That I claim as new, and desire to secure by Letters Patent of the United States, is-

l. 'The combination,in a steam-separator,of an upper compartment having inlet and exit ports, a lower compartment having an inlet and outlet, a partition between said compartments having perforations therein, and a partition in the lower compartment forming a surface overflow.

2. The combination,in a steam-separator,of

an upper and lower compartment havinga perforated division-wall, a transversely-disposed bafle device in the upper compartment, inlet and outlet ports for the same, and an inlet and exit port or ports for the lower com-4 partment.

3. The combinatiomin a steam-separator,ot an upper compartment anda lowercompartment having a common division-wall, a baffle device and inlet and outlet ports in the upper compartment, an inlet-port for the lower compartment, an overflow-exit therefor and a second exit-opening below the water-level thereof. v

4. The combinatiomin a steam-separator,of an upper and lower compartment having a communication between the same, a baffle device for the upper compartment, an overfiowexit for the lower compartment, a secondary compartment communicating with said overflow, and suitable ports for said compartments.

5. The combination,in a steam-separator,of an upper and lower compartment having communication between the same, a bale device for the upper'compartment, an overflow-exit, and a second exit below the water-level of said compartment, a secondary compartment in communication with the exit below the water-level and suitable ports Afor said compartments.

6. The combination ,in a steamfseparatonof an upper and lower compartment, having a perforated division-wall between the same,an overiiow-exit for the lower compartment, a

ries of separate chains or ropes independently suspended therein.

8. The combination of a steam-separator having a series of baieaplate frames located therein, said frames having a series of sepa- IOO .secondary compartment communicating with rate independently-suspended ropes or chains suspended therefrom.

9. The combination, in a steam-separator,of

an upper and a lower compartment having perforated division-wall, baffle devices in the from the latter Compartment, and ports for upper compartment, a secondary chamber the upper compartment. Io Connected with the lower compartment by an In testimony whereof I affix my signature overflow-exit, a discharge-pipe for said seoin the presence of two witnesses.
