JOHN MCKENZIE WARE, OF SHUTESTON, LOUISIANA.
STRAlNER FOR WELL TUBING.
SPECIFICATION forming part of Letters Patent No. 713,544, dated November 11, 1902.
Application filed October 4, 1901- Serial No. 77,606. (No model.)
To all whom it may concern:
Be it known that 1, JOHN MCKENZIE WARE,
of Shuteston, in the parish of St. Landry and State of Louisiana, have invented a new and useful Improvement in Strainers for Well- Tubing, of which the following isa specification.
This invention has for its nature certain improvements in well-tubingof the class commonly known as drive-wells -2 6., tubular or deep wells formed by sinking into the earth a tube shod at its lower end with a piercing point orcutter, all as is well known,and therefore needs no further description.
My invention is designed for and by actual test has proved to be an improvement over the present state of the art.
As is well known, tube-Wells consist of a tube driven or rotated into the ground, the tube at its lower end being perforated a suitable distance from the point end and the said perforations covered in various ways with material designed to allow water to pass into the tube through the perforations and at the same time exclude sand, gravel, the. I am aware that such strainers have been formed by a combination of coverings-such,'for instance, as a smooth straight wire coiled around the tube over the perforationsalso that wiregauze has been used and the said gauze protected in various ways, also that a wire having a small wire twisted around it has been used, and still another form consisting of wire-gauze covered by perforated sheet metal, which is more or less defective, owing to the factthat the covering is frequently torn while the tube is being forced through coarse gravel and loose rock, particularly if the well is sunk by the rotary hydraulic method well known in the art.
My invention is designed to obviate objections to strainers as now constructed, and to that end I have devised a strainer that is not liable to be disarranged or torn while the tube is being sunk, and therefore the invention consists in the specially-formed strainer hereinafter described, and pointed outin the claim.
Referring to the accompanying drawings, forming part of this specification, Figure 1 is a view showing the lower end of a well-tube, the point or cutter being removed and two layers of the strainer partly broken away. Fig. 2 is a central longitudinal section; and Fig. 3shows a modified form of the strand forming the outer layer of the strainer, said strand consisting of a twisted flat metal strip.
In the drawings,Aindicatesa well-tube provided with perforations B, as shown.
0 indicates a smooth wire coiled around the tube with the convolutions thereof spaced, as shown. I
D indicates a layer of wire-gauze, of small mesh, covering the spaced wire 0, and E indicates a metal strand or twisted strip coiled closely around the wire-gauze D, with the twists of the contiguous convolutions in contact, leaving interstices between them,formed by contact of the twists. In other words, the twisted strand or wire E is so wound on the wire-gauze D that the grooves in the strand or wire of one convolution registers with the groove of the next convolution, and thereby providing interstices through which water may freely pass to and through the wiregauze. In winding the outer layer, as stated, the wire-gauze is provided with an armor from end to end, such as will protect its outer surface against liability'of being impaired or torn by sharp or pointed rocks, since it is effectually protected by reason of the convolutions beingin contact. Obviouslyasmooth wire could not be so wound, since such winding would cut off the flow of water.
As. hereinbefore stated, I am aware that a strainer for well-tubing consisting of several layers is not new. I am also aware that such a strainer has been formed of an inner coiled wire, a wire-gauze layer, and an outer layer, formed by a smooth wire coiled upon the gauze layer in spaced convolutions, and I am further aware that a strainer consisting of a twisted strand or strip coiled around the tube with an outer layer of perforated metal is not new.
It is well known that in strainers of a character similar to'my invention designed for well-tubing wire-gauze is best adapted for excluding sand, 850.; but previous to my invention no means had been employed meeting all requirementsi. e., such as would efing torn in the sinking process of the tube.
Previous to my invention the only protectfectively protect the said gauze against be- I ing means employed in such a filter-i. 6., a filter involving two layers of coiled wire and a wire-gauze layer-was a smooth wire coiled upon the wire-gauze with the convoiutions spaced, leaving the gauze unprotected, While by employing a twisted strand or wire, for the reason stated, and arranging the convolutions in contact, as done by me, access to the wire-gauze is not possible, since it is completely covered. In brief, the novel feature in my invention resides in the combination, with the special layers stated, of a twisted strand or wire wound around the Wire-gauze With the contiguous convolutions in contact, leaving interstices formed by the grooves in the strand or wire registering, as stated.
Having thus fully described myinvention, What I claim as new is JOHN MCKENZIE WARE.
