APPARATUS FQR SEPARATING OIL FROM WATER Filed July 15, 1929 Patented May '31, 19 32 PATENT OFFICE,

EULIUS SGHAMBERGER, OF ELIZABETH, NEW JER SEY APPARATUS FOR SEPARATING OIL WATER Application filed July 15, 1929. Serial No. 378,260.

This invention relates to the separation of surface layers of material from bodies of liquid, especially the removal of a film of oil from water. The invention will be fully understood from the following description and the accompanying drawings, in. which Fig. 1 is a erspective view of a preferred 'form of my s imming or separating apparatus, and

Fi 2 is a vertical section taken on the line A- in Fig. 1. f Referring to the drawings, a pair of rolls 1, 1a are mounted for rotation on trunn'ions or shaft extensions 3 and bearing blocks carried by a suitable frame work. This may take the form'of sills 2, suitably connected bycross braces 2a. The rolls 1, 10 may be constructed of any suitable material. For best results the outer surfaces 5-thereof should be smooth in texture and free from irregularities. I have found that glass, polished metal, 'or even woodor paper is suitable for this'purpose. I have for instancesuccessfully used paste board rolls coated with oil resistant lacquer. r a

. Suitable-mechanism is provided for rotating the rolls, as for instance the intermes'hing am 6, 6a suitably secured to trunnions or shafts 3 and adapted to be rotated in opposite directions by the gear 7, which in turn is mounted on the drive shaft 8 of an electric motor 9 or other source of power. Alterna-' tively, a series of pulleys arranged on-the trunmons 3 and carrying cable belts, one of which is connected with an electric motor,

' one gallon per minute, the discharge stream of water from opening 15 of the apparatus mag be used for, the rotation ofthe rolls.

closely adjacent the surface thereof I provide scraper knives or doctors -10,10a adapted'to remove thefilm of oil adhering to the rolls as the latter rotateand transfer it to the tro hs 11,'11a which discharge into a common discharge trough or pipe 12 leading to a receiver 13 or other suitable place of disposal.

, so as to dip below the surface of the water i from which oil is to be separated. This may be accomplished as shown in Fig. 1 by placing the from "c 2 over achannel or slfince-way 14 59 thru which the water flows, the fr e 2 being 1 second roll serves to retard the flow of the longitudinally ofeach roll and In operation the. rolls 1,'1a are adjusted.

adjusted so that the rolls 1, 1a are partially submerged. e

A'baffie 16 extends below the surface ofthe stream at a point located down stream with respect to the rolls 1, 1a to prevent escape of any traces of oil which may not have been picked up by the rolls. This oil will accumu- 1 late on the. surface of the water between the baflle 16' and the roll 1a and eventually be picked up by the roll as it rotates. The baflie 16 thus serves to back, or bank, the oil against the roll 1a. As water carrying on its surface a thin film of oil passes under the rolls 1, 1a which are rotated at a proper rate of speed, the oil film is transferred in whole or in part to the surface of the first roll 1 and is carried around thereon to the knife edge 10 which is setso as'to scrape off this film of oil and'direct it into the trough 11. Any oil not picked up by the first roll 1 is caught by the second roll 4 V 1a as, it rotates in the opposite direction and is removed in similar manner by the corre-!. sponding knife 10a and trough 11a. The

stream sufliciently to back, or bank, the excess oil between the rolls and permits the first roll to pick up most of the oil. I have, for example, been able with a small skimmer equipped with rolls of approximately four inches diameter and twelve inches in length rotating at a speed of one hundred revolutions per minute to remove from the surface of a stream ofwater flowing thru the apparatus, oil at the rate of approximately usually desirable to provide a channel thru which the water carrying a thin of oil is caused to flow, in which case thewalls of the channel ma serve as suitable supports for the rolls. ere such. an arrangement is used it is desirable also to so arrange the channel that the rolls contact with the surface of the stream throughout its entire breadth. The device will usually Be stationary but I contemplate also mounting it for movement with respect to the liquid to be operated upon, While the invention has been described as applied to the separation of a surface la er 5 of oil from water, it will be understood t at other separations can be similarly efiected such as the separation of oil 'from melted parafiin and the like. Other modifications will suggest themselves'to one skilled in the art and while I have described my invention with reference to certain specific details, I wish to claim all modifications and utilizations which come within the spirit and scope of the invention. I claim LApparatus for removing floating material from a liquid, which comprlses a channel for conveying the liquid, a plurality of spaced rolls each extending transversely across the channel in position to dip into the liquid, means for rotating adjoining rolls in opposite directions with the under-surface of the roll u stream rotating in the direction of travel 0 the stream, and means for removing and collecting material adhering to the rolls. i

2. Apparatus for removing a floating surface layer of material from a liquid, which comprises a channel for conducting the liquid, :1 roll extending transversely across the channel in position to dip into the liquid, means ,for rotating the roll with the undersurface of the roll rotating in the direction of travel of the stream, a baflie extending across the channel down stream with respect to the roll in position to dip into the liquid to bank the material passing the roll agamst the down stream'side of theroll, and means for removing and collecting material adher- 40 ing to the roll.

' 3. Apparatus for removing floating material from a liquid, which comprises a channel for'c'onductln the liquid, a plurality of spaced rolls 'eac extending transversely across the channel in position to dip into the liquid, means for rotating adjoining rolls in opposite directions with the under-surface of the roll upstream rotating in the direction of travel of the stream, means for removing and collecting material adhering to the rolls, and a baflleextending across the channel downstream with respect to the rolls in position to" dip-into the liquid to back the material passing the rolls against the downstream roll.
