provement in the art and apparatus therefor.'

It is known that the vapors and gases, which are found with the oil tend, to a greater extent in t-he deeper wells, to obstruct the flow of the oil, unless these vapors and gases are permitted freely to escape.l

This escape, however, involves a loss of the yaporsl-vangigases.- l The fob]ect.,fo:t my invention is first to remove .thefvapors and ases, so that the oil may b e freely and ful y pumped; and in the second place, to conserve the' vapors and gases, so that they may be utilized; and finally and coincidentally with the securing of the second object, I save other elements of the oil left in the pumping, in the stratum from which the oil is drawn.

While I do not conine myself to any special form of apparatus, I have shown, in the"y accompanying drawing, in diagrammatic form, an apparatusin place, well adapted to carry out my methods, which constitute the main art of my invention., 1 In t is drawing, A represents an upper, and B a lower stratum of oil bearing material, such as sand rock or shale. The boring or wellis indicated at D. In this is placed a large pipe 2, extending near to the ottom of the well, and having a gastight packing 3 at its lower end on the outside, so that the ases or vapors, risin from the stratum for exam le) into whlch the well opens, will all'be irected into the large pipe 2. The upper end of this pipe opens 1nto a gastight 21:1 4, from which extends a ipe 5, to ap p 6, whereby .the gases an vapors are exhausted from the well, and L the oil, having been freed from the obstruct1on of the co umn of such gases and vapors, 1s fieelgl pumped bymeans of any ordinary pump p to 1ts tank 8, the pump 7 passing centrally wlth gastight joints through the box and large. pipe 2.-

It will be observed that the pipe of the pump 7 extends into the .cavity'below the mouth of the gas pipe D, so that the oil, by its greater specific ravity, is below the gas exit, and free there rom. .The oil pump and the gas and vapor ump work independently and draw from di erent points, the one from the point of communicationvwith the vapors and gases, and the other from that of the oil.

It is also known that many wells in the same neighborhood, are exhausted, while others continue to flow. These emptywells,

and the strata with which they communicate, I utilize for the conservation of the gases pumped from flowing wells. Such empty wells are shown at E and F, one in stratum A, and the other in stratum B. In these I place respectively, the large gas pipes such as that shown at 2, constructed and packed in place in the way above described. g To these pipes are extended from the forcing side of the pump, a pipe 8, with branches 9,

whereb the ases or vapors, drawn from the active wel are forced into the stratum or strata, which had been exhausted, and thus, without material expense, these gases and vapors, are-conserved, and may be retained indefinitely, for subsequent use. I

find also, that the gases and vapors, thus forced into the exhausted well, and its connected stratum, find therein residue such as benzin, naphtha, and gasolene, and these the vapor or gas takes up, so that upon pumping them out these residual elements are saved, since they may be thus easily recovered, I

I claim The apparatus herein described consisting of a as or vapor pipe in connection with the oiI and gas strata, an oil pipe extending below the end ofthe gas pipe, a pumping device for the oil, a as discharging pipe leading to an indepen ent exhausted 011 or gas strata, and an intermediate pipe line etween the gas pipe of the active well and the discharge pipe of the abandoned well, with means for forcing the gas into the abandoned well, substantially as described. i

In testimony whereof, I atHx my signature in presence of two witnesses. f
