To all whom it may concern:

..?^e i/ known that I, John P. Firth, of Titusville, in the county of Crawford and State of C ^ania’^{liave mvent}ed certain new and useful Improvements in Apparatus for Removing Gummy Matter from Oil-Wells of “ ^ω1· “0 tecta elyremoving the gummy matter and other substances accumulating on oil-rock thereby permitting a free flow of oil from the 15 zr^{ently increasing the}

The invention consists of a receptacle having openings and held to slide in Hie rock being connected by a conducting-pipe with a ~ ££ °,^r “^aer₍riw.» »to : 20 steam, &c., on the oil-rock.

Reference is to be had to the accompanying XT?¹’ ut^{part of this} specification¹^ in which similar letters of reference indicate corresponding parts in all the figures.

Serial No. 288,763, (No model.) the said receptacle and forms a beari ng for the tubing B, which passes through the said pipe D'.

In the modification shown in Fig. 4 the re- ςς ceptacle D is of half-moon shape and the tubing B fits into the inner surface of the halfmoon, so as to hold the reeeptacle D loosely on the tubing B.

In the modification shown in Fig. 5 the ex- 60 tenor cylindrical .shell of the receptacle is not pei forated; but the bottom D³ of the receptacle is somewhat lower than the lower edge of tne shell, so as to form an opening through which the fluid can be discharged from the re- 6? ceptacle. ⁰ l he upper end of the supply-pipe E is connected with a suitable mechanism for raising and lowering said pipe E. I prefer the conϊίΤίθΛ^sll?^wni^{n Pi}g·· L ni which the upper 70 end of the pipe E is connected with one end ot a rope, I, extending upward and passing oyer a pulley, J, mounted to rotate at the top of the usual derrick, K, erected over the oilwell A. l he rope I then extends downward from the pulley J to the drum of the windlass L, which serves to raise or lower the pipe E ana the receptacle D in the oil-rock strata.

When the flow of the oil-well A decreases the oil-bearing rock is clogged up at the entrance to the well A by gummy matter or other substance, and in order to remove thisg-ummy matter I charge the receptacle D with steam, benzine, or other fluid at the top of the latter from the tank H or from a steam-boiler, so that the steam, benzine, or other substance passes through openings in the receptacle D onto the oil-bearing rock with considerable ' ^{D U}P and lowers the supply-pipe E, supportinTlt ts
