`.Application filed. March 12, 19215.V -Seral'Na 13,974. (DEDICATED 'ro :rHnruBL-Ic.)
ToJaZZ whome'tmag/ concern v@Be it A'known that I,\fRoBERT S'roonnn, a citi-Zen of the United States, residing at Brooklyn, in the county of Kings, in the State of New York, have inventedY certain new and useful Improvements in Pipe-Lin ing, and of which fthe following is a specification.
Under the actofHMa-rch 3, V1883, the invention herein disclosed may be used by the* Government, or any of its officers or employees,fand by contractors of lnaval or other Government vessels,` without payment of royalties.
yMyinvention relates to -pipe lining, and more particularly to lead lined piping where the iinishedpipe consists of inner 1 and outer tubing, wherein pressure may be createdV between the two tubes due -to the presence of air, water Vor other expansive substance, due to variations in tempera-ture, pressure, or other causes.
The objects of the invention are toprovide a means 'for preventing or relieving `the said pressure betweenthe two tubes and thus prevent collapse of one of the said tubes. The sought means Vof relief may be disposed locally or through the entire length of the pipe.
The invention consists, broadly speaking, of suitable perforations in the inner tube, or in the outer tube, `orin both tubes. The perforations may consistof drilled holes or produced by any other means orof any shape, size or number, as may bestysuitthe farticular installation.
The present ordinary 4form of plain lead lined piping is experiencing much trouble. In this application I make use of plain linedvpiping and of corrugations as shown in my former application but overcome the defects, viz., the bulging between the elements due to changes -intemperature and variations in pressure which produce bulging land then pulsations of the' bulged parts, which ultimately causes fracture, by the in-v troduction of an escape means for the pressure generated by gases, vaporization, or other causes, the said means being in the form of the perforations above referred to.
Before describing'my invention in detail I wish it understood that I do not intend to limit myself to any particular method of theA different requirements of manufacture,
or purpose for which used; or, in fact, to make any mechanical changes -so long as I do *not-depart from the broad spirit of the invention asset forth in the annexed claims.
f-In thedrawings forming part of this application Figure l is a longitudinal `sectional elevation of a pipe showing Ythe circumferential outward corrugation of the outer and inner elements, the said inner element being perforated. Fig. lA is a longitudinalsectional elevation of a pipe showing a circumferential outward corrugation of the outervand inner elements, the said outer element being perforated. Fig. 2 is a longitudinal sectional elevation of a pipe showing circumferential inward corrugations of the outer and inner elements, the said outer element being perforated. Fig. 2A is a longitudinal sectional elevation of a pip-e showing circumferential inward corrugations of the outer and inner elements, the said inner element being perforated. Fig. 3 is a longitudinal -sectional elevation of a pipe showing a spiral inward corrugation of the inner element, the said outer element being perforated. Fig. 3^ is a sectional elevation `of a pipe showing a spiral inwardV corrugation of the inner element, the said inner element being perforated. Fig. 4 is the same as F ig. 3 `with the addition of a supporting -means for the corrugations. FiglA is the same as Fig. 4 except the perforations are disposed in the inner element. Fig. 5 is a longitudinal sectional elevation of a pipe showing a spiral outward corrugation ofthe outer element, thesaid inner element being perforated. Fig. 5A is a longitudinal sectional elevation of a pipe showing a spiral outward corrugation of the outer element, the said outer element being perforated. Fig. 6 is the same as Fig. 5 with the addition of a supporting means for the corrugations. Fig. 6A is the same as Fig. 6 except the perforations are disposed in the outer element. Fig. 7 is a longitudinal elevation of a section of a pipe showing lead lining tted in the ordinary way, thatis without corrugations and in which are shown the manner of providing the escape means for fluids or gases that may generate between the elements, in this View the escape means consisting of a plurality of holes are shown in the outer member; obviously these holes may be formed in the inner element if kthe conditions warrant. Fig. 8 and Fig. 9 are part sectional views of two types of ends of pipes showing the escape holes in the outer element and in the inner element respectively near the points of the flange connections; obviously the holes may be formed in either inner or outer elements, and in number and disposition as desired.
Referring specifically to the drawings in which like reference characters denote like parts, 1 is the outer element of the pipe while 2 represents the inner element, 3 being a corrugation in the outer element and 4 the saine in the inner element, 5 represents a wire, cord or other substance of circular or other cross-section that may be used at times if'desired to prevent the collapse of the corrugations when the latter is only in one element, 6 represents holes in the inner element while 7 represents holes in the outer element. Obviously in some instances, the wire, or cord, may only be used to assist in the formation of the corrugations in the process of manufacture and may afterward be withdrawn if the purpose for which the pipe is to be used permits.
The process employed in the lining of piping or tubing either inside or outside may vary according to conditions, but in some cases may be accomplished by formingl the corrugations in one element and then assembling the two elements and forming the corresponding corrugations in the other by the application of a suitable liquid or gaseous pressure applied externally or internally as the case may require. The manner of forming the holes may be varied to suit conditions but in some cases I may conclude todrillthein before the pipe elements are assembled.
Having thus described my invention, its objects, advantages, etc., I claiinz-Y 1. A pipe having inner and outer tubular elements, an escape means from the space between the said elements, the said escape Copies of this patent may be obtained for Vthe tubular elements means being formed in the wall of one of the tubular elements. Y p' Y 1 2. A pipe having inner and outer tubular elements, an escape means from the space between the said elements, the said escape means being formed in the wall of one of and corrugations formed in the wall of one ofthe said tubular elements.
