OIL-PURIFIER.

i Sp'ec ification of Letters Patent. Patented Apr 1917,

Application filed June 6, 1916 Serial No. 111L953.

To aZZ wkOmit may concern: I

Beit' known that I, JOHN F. ROBERTSON, a citizen of theUnited States, and resident of Bellevue, in the countyof Allegheny and. State of Pennsylvania, have invented a new and useful Improvement in Oil-Purifiers;-

andI do hereby declare the following to be a full, clear, and exact description thereof.

My invention'relates to an oil purifier or filter, the object of my invention'being to providea compact apparatus of this charac v tor which is simple in construction, and in" which large quantities of oilcan be purified rapidly while, at the same time, the parts are accessible and capable ofremoval for purposes of cleaning or repair,rand .without interruption to the general operation of the filter. 1 p 1 My invention comprises the novel features hereinafter set forth and claimed.

In the accompanying drawings, Figure 1 is a side elevation, partly broken away, of?

my improved filter; Fig.v 2 is a plan view with top removed; Fig. '3 is an enlarged section on the line3-3,-Fig. 2; and 4 is an enlarged section on the line 44, Fig. 2.

In the drawings, the numeral 2 designates a suitable casing made up of plates of metal of proper thickness and united to form a strong rigid structure. Within the casing 2 is the reservoir 3 to receive thedirty oil.

The oil is delivered to the reservoir 3 through the inlet-pipe 4 provided at its upper endwith the strainer 5. .This inletpipe '4 extends down within the tank to the I lower end thereof, or what may be termed the settling compartment 6. r

The reservoir 3 is provided with the steam-jacket 7, which may extend only for a portion of the height of said reservoirwithin the zone containing the oil, and this steam-jacket is supplied with steam from the steam inlet-pipe 8. v

The pipe 9 extends downwithin the reservoir 3, said pipe having the connections 10, 11 and12, with 'the'pipes 13, 14 and 15 connected to said connections, respectively, and said pipes being provided with the valves 16.

These pipes 13, 14 and 15 deliver the oil rising in the pipe 9-tothepans17, 18 and 19, respectively. These pans rest upon suitable supports 20 and are arranged to slide in and out onsaid supports so that the pans may be removed independently of each other, as more fully hereinafter set forth.

The pans are provided with steam-jackets 21 supplied with steam from the pipe 22, which is connected up with the steam-pipe 23 from the steam-jacket 7 ofthe reservoir 3.

Valves 24 are provided to control the supply of steam to the steam-jackets of the different pans.

The interiors of the pans are provided with the baffles '25 extending in oppositedirections and overlapping each other, as'indicated in Fig. 1 so that the oil on entering the pan at one end is compelled to pass in a tortuous course from one end of the pan to the other, giving the sediment and foreign matter in the oil an opportunity to settle beforethe oil finally escapes by the outletpipes 26'. These outlet-pipes discharge the oil into the filter bags 27 whence the oil drips from said bags into the clean-oil compa ament 28.

ervoir, and has the movable spout 35 connected thereto. This spout delivers into the i funnel 36 at the upper end of the drain pipe 37, leading to the. drain 38." The water mixed with the dirty oil will settle in the settling compartment, being heavier than the oil and will rise within the ejector-pipe 33, being forced up therein by=the weight of the oil. f

,Goose-necks '39 leading'from the steamjackets of the pans carry off the condensation, which is deli-vered'into the wastepipe;40. g i The casing '72is provided with the doors v 41 by which access is had to the pans, and i with a door '42by which access is'had to the filter-bags. I Q v Thedirty oil is introduced into thepipe 4, passing through the strainer 5 and down through saidpipe into the lower end of the reservoir 3. The oil will rise in the reservoir, the water, as stated, settling to the bottom and being forced up through the pipe 33 to the drain. As the oil rises in-the reservoir 3, it is heated by the steam-j acket 7 and a portion of the dirt or foreign matter will settle in the lower end of the reservoir to be drawn off from time to time by the wastepipe 44. As the oil rises in the reservoir, it will enter the pipe 9 and will be carried off by the pipes 13, lt and 15 to the pans 17, 18 and 19, respectively. The oil discharged into the pans is retarded in its flow by the battles and is compelled to take a tortuous course, which permits of the deposit of the dirt in the pans While, at the same time, the oil is heated by the steam-jackets, and this further aids in the deposit of the dirt. The oil finally passes by the pipe 26 into the filter-bags 27 and thence down into the cleanoil compartment to be drawn off by the pipe 30.

"When it is desired to remove one of the pans for purpose of cleaning, or for other reason, the steam-pipe connection to the water-jackets is disconnected, and the pan can then be readily removed by withdrawing it.- It should have been stated that the valve 16 is first closed so as to prevent the discharge of the oil from the pipe 15. The pan in this manner is removed and cleaned or repaired as the case may be, and' is then re-inserted in its proper position and the steam-pipe connected thereto, whereupon it is ready for further treatment of the oil. In this manner, I provide for the removal of the pans independently of each other, and, by having them arranged in the manner described, this is efi'ected without disturbing the operations in the other pans and, in this manner, the filter operates continuously even though one or more of the pans may be out of operation.

By my apparatus, I provide for the cleaning of a greater quantityof oil in less time while, at the same time, the apparatus is very compact and, due to the heating of the oil by the steam-jackets, the operation of cleaning the oil is rendered very much more effective and more rapid thereby decreasing the cost and giving a greater saving in oil.

What I claim is:

1. In an oil purifier, the combination with a suitable frame, of a reservoir for containing the impure oil, a plurality of settling pans supported in said frame, means for delivering the oil from said reservoir to said pans, and means for removing said pans independently from said frame.

2. In an oil purifier, the combination with a suitable frame, of a reservoir for the impure oil, a plurality of settling-pans mounted in said frame one above the other, means for delivering the oil from said reservoir to said pans, and means for removing said pans independently from said frame.

Copies of this patent may be obtained for 3. In an oil purifier, the combination with a suitable frame, of a reservoir for the impure oil, a plurality of settling-pans mounted one above the other in said frame, means for delivering the oil from said reservoir to said pans, and means for withdrawing said pans horizontally from said frame the one independently of the other.

4. In an oil purifier, the combination with a suitable frame, of a reservoir for the impure oil, a plurality of settling-pans mounted therein, independent means for delivering the oil from said reservoir, and means for removing said pans from said frame independently.

5. In an oil purifier, the combination with a suitable frame, of a reservoir for the impure oil, a steam-jacket surrounding said reservoir, a plurality of settling-pans mounted in said frame one above the other, means for delivering the oil from said reservoir to said pans, and means for removing said pans independently.

6. In an oil purifier, the combination with a suitable frame, of a reservoir for the impure oil, a pipe extending down into said reservoir, a plurality of settling-pans mounted in said frame one above the other, connections from said pipe to each of said pans.

7 In an oil purifier, the combination with a suitable frame, of a reservoir for the impure oil, a pipe extending down into said'reservoir, a plurality of settling-pans mounted in said frame one above the other, valve controlled connections from said pipe to each of said pans.

8. In an oil purifier, the combination with a suitable frame, of a reservoir for the impure oil, a plurality of settling-pans one above the other mounted in said frame, means for delivering the oil from said reservoir to each of said pans, an overflow pipe leading from each of said pans, and a filterbag communicating with each of said overfiow pipes.

9. In an oil purifier, the combination with a suitable frame, of a reservoir for the impure oil, a plurality of settling-pans mountcdin said frame one above the other and independently removable therefrom, means for delivering the oil from said reservoir to each of said pans, and a reservoir for the pure oil overflowing from said settling-pans.

In testimony whereof I, the said JOHN F.

ROBERTSON, have hereunto set my hand.
