REINHOLD BOEKLEN, OF BROOKLYN, NEW YORK.

IMPROVEMENT ,IN OIL-EJECTORS.

Specification forming part of Lettersl Patent No. 51,008, dated November 21, 1865.

To all lwhom it 'may concern:

Be it known that I, REINHOLD BOEKLEN', of the cityof Brooklyn, in the county of Kings and State of New York, have invented a new Mode of Elevatiug Petroleum from its Wells; and 1 do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, which represents a vertical central section of a well to which my device for elevating thepetroleum is applied.

.Similar letters of reference indicate corresponding parts in the drawing.

The nature of my invention consists in an 'apparatus whereby the petroleum is raised to a proper discharging-point upon a body of water and against a body of air, and from this point discharged through a tube of said apparatus at the top of the well.

One form of apparatus which is adapted for carrying out my invention may consist of two tubes, one within the other concentrically, the inner tube having a weighted indicating-valve at its top, the outer tube admitting an influx of water, the inner an influx of air, until the oil in the Well rises above openings near thebottom of the central and deepest tube, when the inux of air ceases and the continued inux ot' water through the outer tube, or the increase of oil in the well from its surrounding sources, causes theoil to ascend through the center tube, and

by its pressure overcome the resistance ofthe graduated weight upon theY valve, and thus expel all resisting air in the tube, and by iiowing through the valve-passage indicate to the superintendent that all is going on right, and that the escape or discharge cock ator near the ktop of the tube. should be opened.

t To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

Arepresents an oil-well; B, the mouth o r bore of the same.

Gis a tube, which is as large as the bore less the space required for it, to'be packed in the usual way with seed-bags, but with a great deal more care, and as near as possible to the entrance into the well, in a manner to make an air-tight joint at the aforesaid place. This may-be done by using a packing which may be expanded by means of havin g a stuing-box Y connected with the top of the bore, or having an air-tight bag around the said tube C, which may be expanded by charging the same withcompressed air or water.'

D is an air-tube, and is within the tube C. E is a pipe provided with astop-cock, F, and

connected with au air-pump. G is a stop-cock,

also connected with the air-tube D.

H is an air-valve on the top of the tube D, and is held to its seat by a lever, I, and weight J, the said lever being marked to indicate the pressure against the valve in pounds or otherwise; but the valve is made in a manner that it can be removed.

K is a water-reservoir connected with a pump by a pipe, L, and connected with the tube C by a stop-cock, M. l

The operation upon the well is as follows: The dept-h of the well is rst determined prop- "e'rlyand from this is calculated the necessary pressure to raise a column of oil from it to the top of the tube D. The apparatus is then set ready for operation, all the stop-cocks closed, and the weight J placed on the lever I to press on the valve H with a pressure equal to raise the oil in the tube D corresponding with the calculation made before. Now the air-pump is set to work and the stop-cook F opened and the air compressed in the well until the Weight J is raised. Then the cock F is closed and the air-pump stopped, the cock M opened and the water-pump set in motion, whereby the Water from the reservoir K tlows down to the bottom of the well and gradually raises the oil until the same appears coming out through the valve H, at which time the cock Gr is opened and the pressure in the tube D entirely removed, whereby the oil will flow freely off the cock G. The water should not be supplied any faster to the well than the oil escapes from it, and the valve H should be carefullyY watched so as not to be loaded too little or too much before the oil is coming to it.

`From the foregoing the mode of raisin g 1n ay be clearly perceived. The compressed air has to take the place of the gases usually contained` in the well when the operating 'is first begun, and the water-pressure is used toelevate the oil and to take the place of the oil formerly containedin it.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. Raisin gpetroleum from its wells by means of acombilued air and water apparatus, which 3.
