OIL-SEPARATOR.

Among the objects of this invention is tol so construct a device of the character indicated whereby a more thorough separation of the lighter from the heavier liquids will be effected.

A further object of this invention is to provide for a more thorough and satisfactory disposition of the oils or other lighter liquids.

The foregoing and many other objects of this invention will hereinafter be more fully described and' claimed and illustrated in the drawings forming a part of this specification in which like charactersof reference indicate corresponding parts in all thc views, and -in which- Figure 1 is a vertical sectional view substantially on the line 1-1 of Fig. 2, showing a preferred embodiment of the invention; Fig. 2 is a horizontal section on the line 2-2 of Fig. 1; Fig. 3 is a transverse vertical section on the line 3`3'of Fig. 1; Fig. 4 is an end elevation with certain parts in section on the line 4 4 of Fig. 1; and Fig. 5 is a rear elevation, parts being broken away.

The several parts of this invention may be madeof any suitable materials, and the relative sizes and proportions, as well as the general design and arrangement thereof, may be varied to a considerable extent. without departing from the spirit of the mvention hereinafter specificallyclaimed.

Referring to the drawings, l show at l() a receptacle constitutingthe principal part of the separator mechanism, the same having leading into one end a pipe 11 into and through which the mixture `of various liquids to be treatedis delivered to the receptacle 10 at a point 12 substantially close to the lower part of one end.

'any suitable source, and for convenience of description such mass of fluid'may be regarded as consisting of water and various oils of different characters as to lightness and volatility. The apparatus comprising the principal parts of this device will be understood as being located at any Asuitable place such, for instance, as below the floor of a garage or other building in which mixed masses of oil and water are subject to accumulate.

The separator 0r receptacle 10 is shown as Ibeing substantially of rectangular con: figuration and comprising two general compartments, one, the separator 16, and the other, an oil receptacle 17. The separator portion 16 is shown comprising a series of receptors, shown at 18, 19, 20- and 21, although it will be understood that the number and arrangement of the receptors may vary from the disclosure herein made. The receptors are constituted by a series of bafle plates which extend transversely across the interior of the separator 16, but there being provided fluid communication from one receptor to the next.

The mixture flowing through the inlet 11 is discharged into thereceotcr 1 8 against a downwardly projecting baille plate 22 which is solid where it extends over the mouthof the pipe 11, but which is provided wlth numerous perforations 22 adjacent its end s through which a certain portion of the oil may pass directly upwardly into the recepn *tor 18, the bulk of the mass, however, being deflected downwardly ftoward the bottom of' the receptor 18 and any heavy insoluble particles conveyed by the fluidwill be deposited into a trap 23 normal-ly closed by a plug 24.

.and through which said deposit may be withdrawn from time to time.

receptor is upwardly between the baflle plate 22 and the front wall of a U-shape'd baille plate 25. A considerable portion of the oil will be separated in the first receptor and will flow to the top, as indicated at Q6, where the separated oil which may still remain in the mixture will be carried forward and downward between the batlieplate 25 and-.a

The course. of the fluid mass from the bottom of the first partition 27, the course of the fluid being indicated by the arrows on F ig. 1. Another portion of the oil will be separated by gravitation in the second receptor 19 and will fioat to the top as indicated, and so on throughout the separator, the proportions of oil becoming gradually smaller as the outlet end of the separator is reached. f The water from which the oils have been separated as the fluid masspasses through all of the receptors passes into and through an outlet pipe 28, the mouth of which is shown at 29 as being very broad and comparatively shallow whereby the maximum outflow is insured with a minimum variation in rise of the surface of the mixture or `oil in the separator. A check valve 30 is provided in the discharge pipe 28 so as to prevent any possibility of the device becoming flooded by the stoppage of theV main sewer or drainage from the building. Since the specific gravity of the entire mass in the first receptor is less than in any. of the succeeding recep tors, the normal surface level at the top of the oil therein will be slightly higher than in the next receptor.

Any suitable'means may be devised to dispose of the oil or oils separated from the Water. If the oil is gasolene, or some otherlirrht volatile oil, the bulk of it may pass off freely and be carried out through a pipe 31 leading upwardly from the top of the separator, draft being provided by means of an inlet pipe 32 at the opposite end. Any suitable means such as a fan 33 may be provided to augment such draft, and the force or volume of the same may be regulated according to the temperature or the nature ofthe oils by means of a gate valve 34, by way of illustration.

A closed heating coil 35 through which may be passed steam, hot water or the like,

is arranged horizontally within the separat-V ing chamber 16 and incontact with or close to the surface of theoil for the purposeof augmenting the levaporation of the oil. Such coil is shown as entering the rear end of the separator and after passing around over the receptors emerges from the same end. The loop or coil of the heater is shown as being supported upon the bame plates 27 and 27.

I preferably arrange said coil with two substantially parallel legs which extend along on opposite sides of the line joining the air inlet and outlet.

An overflow opening 36 is provided adjacent the top of each receptor, the same leading into the oil receptacle 17. The effective height of the overow through each of the openings 36 may be regulated by a plate 37 adjustable through slotted ears 38 I. and bolts 39 as shown best in Fig. 5. My

object in making these openings adjustable is to maintain a substantial uniformity of 4 receptors, and such adjustment is necessary because of the great variety as to character or specificgravity of the oils which may be separated from the mass according to the peculiar industry With which the apparatus may be used. The heavy oils or gelatinous products which are discharged through the openings 36 and collected in the receptacle 17 may be disposed of in any suitable manner when sufhcient accumulation thereof is obtained. In order to provide safety'with respect to overflow, I employ some suitable automatic means including, for instance, a float v40 Within the oil receptacle, the float being carried by an arm pivoted at 41 having communication with a balanced valve 42 associated with any suitable signal mechanism, for instance, a Water pipe 43, the armay see it. The, oil may be dipped or pumped from the receptacle 17 as occasion may require, but it may be drained from the bottom through a stop cock or drain 44. Other drains 45 may be provided for the several compartments of the separator 16,

if desired. I also preferto employ a sight glass 46 on the outside of the oil receptacle for the purpose of observing the level of the oil. A'n auxiliary heating pipe or coil may `be provided in the oil receptacle, as shown at 47, for the purpose of facilitating the manipulation of the oil.

I claim:

1. The herein described Huid separator comprising a series of receptors havingcommunication with each other at their bottoms, means to deliver uid mixture in the first receptor adjacent its bottom, a curved baille plate Within the first receptor serving to direct the mixture downwardly, said baffle plate'being imperforate adjacent the mouth. of the delivery means and being performed remote therefrom, and means to deliver the loil from the upper portions of said receptors.

2. In an oil separator, the combination of a receptacle comprising a series of receptors having communication each to each. at their bottoms, means within the receptacle serving to break up the mass of oil and water, an oil receptacle extending along one side ofthe first mentioned receptacle adjacent the ends of all ofthe receptors, each receptor having an opening adjacent its top through which the lighter fluid :may flow into the oil receptacle, the several discharge openings being at different elevations from one end of the series to the other, adjustabley plates associated-With said openings whereby the effective levels thereof may be variably regulated according to the different characters of fluids being treated, and means to facilitate the movement and discharge of the oil separated from the water.

3. Inan oil separator, the combination of a main receptacle, a pipe to deliver a Huid mixture into ythe receptacle, a downwardly extending deflector against which the fluid is directed as it enters th`receptaele,`saiL delector extending transversely of and beyond said delivery pipe and being imperforate opposite said pipe'and perforated at its ends, a sandtrap associated with the receptacle below the imperforate portion of said defiector, additional means within the receptacle serving to break up the mixture whereby the lighter portions may be separated from the heavier portions, means to drain off the heavier portions of the Huid in one direction, and means to dispose of the lighter portions in another direction.

4c. In an oil separator, the combination of mixture into one end of the receptacle, means within the receptacle serving to break up the mixture to facilitate the separation of the oil from the water, means to permit the outfiow of the water from the opposite end of the receptacle, and means to dispose of the oil separated from the water, such oil disposing means including an air inlet at one end of the receptacle communicating with the oil space-andan air outlet from ano'tleru"Vrrr 'Y portion of the oil space whereby suitable draft of air is caused through the receptacle, and a horizontal closed heating coil extending from one end of the receptacle to the other above the surface of the fluid therein and on opposite sides of the line joining said air inlet and outlet.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
