This invention relates to oil feeding systems for hydro-carbon burners and has for its object a system adapted to filter and prepare the o-il for combustion in a burner used in connection with smelting furnaces or other high temperature furnaces. f

It has for its object a system which is adapted to thoroughly filter thecrudeoil before it is admitted to the burner and that is so arranged that the sediments or refuse resulting from the filtering process may be readily removed when desired.

A further object is a heating of the oil to prepare vit for volatilization and' mixing with the air. This heating arrangement is so arranged that heating the oil in no way interferes With the feeding apparatus and so that the temperature is under the control of the operator of the furnace.

Inthe drawings z-Figure 1, is an elevation of the piping forming the oil feeding system. Fig. 2, is a vertical section of the filter, the furnace, the stack which surrounds the filter and the connection lwith the furnace. Fig. 3,. is a detail of the support for the heat-Vent gate, Viewed from the left of Fig. 2 with the union removed.

A, is the furnace built of refractory brick ywhich has an inclosing shell 1, to which is `bolted. a pipe union 2 that connects the heat- .vent 3 with the aperture 4 in the furnace wall. This laperture is lined with a metal lining 5. The heat-vent 3v at -`its outer end turns and enlarges, forming a stack 6. This stack is adapted to contain a filtering tank 7 which kcomprises a pair of cylindrical tubes screwed together. It will be noted that the vent 3 is bolted to theunion 2 and it may be detached, and dropped to secure access to the filter. The cap 8 screws over the top of the upper tube and the plug 9 screws into the bottom of the lower tube. The oil is introduced into the bottom of the filter through the induction pipe 10 and it flows out of the filter through the eduction pipe 11. These , pipes 10 and 11 screw into the plug 9 and cap 8, respectively. The interior of the tank 7 is filled Witha filtering substance. I prefer to use a section of hair 12 at both the top and bottom. The Vspace intervening befilter material and in this arrangement for' coarser thanV thesteel Wool. The section of hair at the bottom of the filter is located at a position where most of the sediment drops or sifts through. The steel wool is located at the center and forms the smaller interstices of the two filtering materials, but inasmuch as it is located at center it -is in no danger of clogging the eduction or induction pipes and interfering with t-he fiow of oil or the action of the pumps, it being understood that the oil is pumped through4v the filling material under pressure, there being a pressure of about twent -five pounds to the square inch. This a ords force to send the crude oil, which I prefer to employ, through the small interstices of the filtering materlal which detaches nearly all the sediment and impurities therefrom.

at the bottom. This is so that the oil can leave the top without carrying with it sediment or impurities that have collected in the filter. Such sediments and impurities is taken through from top to bottom', some of the impurities that have collected in the Abottom are quite apt to be carried into the eduction pipe.

It will be noted that I have provided a threaded aperture 14 in the side of the lower tubulai member into which screws a plug 15. 'lhis plug can be removed and access had to the filter for removing the sediment.

The heat-vent 3 is provided with an eX- teuding piece 16 at the end Where it is bolted to the pipe 2. This extending piece is slotted at 17 and in this slot runs a winged screw 18 that is screwed into the gate 19. This gate serves as a control for the heatvent 3. By loosening the screw the gate may be ralsed and lowered as the screw travels in the slot and by tightening the screw upon the extension piece, the gate is supported in any desired position of adjustment. Some of the hot gases of the tween these sections is filledwith steel wool as indicated at 13 in Fig. 2. I employ .this

the reason that the hair is considerably It will be noted that I introduce the oil p settle toward the bottom and when the oil interiorl of the` furnace are abstracted through the heat-vent pipe and pass out into the stack 6, enveloping the oil filter 7 and are free to` pass outat the o-pen top into the stack. It will readily be understood that by regulating the position ofthe gate 19 that aconstant temperature may be maintained, or any iuctuatingptemperature that is desired. The intensity of the' heat inv the stack isat alltimes indicated by a thermometer 20 on the side ofthe stack.

. The oil is brought to the induction pipe' by piping 21, part of which is ordinariiy cut out by the cutout valve 22 and the flow of oil is through the meter branch 23, which carries it through the oil meter 24. I locate the oil meter on the pipe line so that it is operated upon by the oil before the same is hea-ted, as the heated oil has a tendency to interfere with the operation of the meter. The cut-out valve may be opened and the meter branch 23 out outby closing .either of the valves 354 and 36. The cut-out valves may be closed and the induction pipe `l() broken in two, by unscrewing the coupling 39. This allows the dropping of the-stack to reach the filter. Y A

The eduction pipe vl1 extendsI away ,horizontally vfrom the top of t-he filter, thence turns in 'a downward direction and drops to a pointbelow the burner 25. In the downward drop of the eduction pipe 11, a cut-0H valve 26 for the burner is located. The burner feed pipe 27 joins the eduction pipe 1l at a point below the burner and Ileads up from below into' the burner. This drop of the feed pipes below the burner, so that they feed the burner from below,has ay distinct purpose. Itwill be noted that the coupling 28 that joinsthe feed pipe 2T with the eduction pipe 11 has a flush lvalve 29 so that it mayfbe readily flushed. This is to take off any, of the impurities or sediment which have escaped the filter and which 'naturally tendy to collect in this loop of the piping below the burner.

The burner 25 is controlled by a valve 30 and fed 'with the oxygen necessary for combustion by the air . pipes 31 and 32, but ina-smuch as the construction of the burner and the supply of air to it is not part of this invention, I have not described them. 1
