PAUL OASAMAJOR, OF NEW YORK, N. Y.

IMPROVED MODE OF OPERATING OIL-WELLS.

Specification forming part of Letters Patent NO. 50,902, dated November 14, 1865.

To all whom it may concern:

Be it known that I, PAUL CAsAMAJoR, of the city, county, and State of New York,have invented a new and Improved Mode ot' Operating OilVells; and l do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part ot' this specitcation, in which- Figure 1 represents a vertical central section ot' this invention. Fig. 2 is a horizontal section ot' the same, the plane ot' section being indicated by the line x x, Fig. 1.

Similar letters ot' reference indicate corresponding parts.

The usual method ot1 operating oil-wells is to sink awell ot' a diameter ot' four inches, (more or less,) and after tubing the same to raise the oil bysuitable pumps. By this method only that oil is reached which is incloscd in crevices that are'pierced by the well, and in order to reach all the oil in a certain tract ot' land it is necessary to sink a large number otA wells.

This invention consists in extending from a central vertical main well a series ot' radiating' drills in a horizontal or inclined position in such a manner that a communication is et'- i'ected between the several crevices situated outside the main well and not otherwise in communication therewith, and all the oil contained in a certain tract ot" land can be collected in thc main well and raised by one and the same pump without the necessity ot' sinking a large number ot' wells and removing the pump from one well to the other.

A represents a well, which, howeveigis made of a much larger diameter than that generally given to oil-wells, and which will have to be dug out. or otherwise produced by suitable machinery. The upper portion ot' thiswell, which is supposed to pass through slate-rock, is protected by planks a, to prevent the ground from tumbling in, and its lower portion is lined with a crib, I), of cast-iron or other suitable material, which may be provided with suitubleribs to keep it properly in the centerot' the well, or which maybe steadied by othersuitable means. The well extends through the said rock containing the oil,and in order to reach such crevices which are not struck bythe well l erecta platt'ornnc, ata suitable height above the bottom ot' the well to enable the men to stand on, and then I extend a series of radiating drills, d, in a horizontal or inclined direction from the well A,as shown in Fig-.2 ot' the drawings. These radiating drills may he continued to any desired distance trom the main well, and by the same a communication is opened between distant crevices and the well, and the oil contained in an extensive tract ot' land can be collected in one and the same well.

Suitable galleries may be d ug in the side ot' the main well to protect the workmen in drilling the radiating` holes, and the operation of drilling these holes may be etected by hand or by suitable machinery.

A pump placed in the main well serves to raise the oil in the ordinary manner.

l claim as new and desire to secure by Letters Patent- The within-described method ot' operating oil-wells by extending from the main well A a series of radialingdrillsorchannels, d, in a horizontal or inclined direction, substantially as and for the purposes set t'orth.

P. OASAMAJOR.
