CONDUlT-PIPE.
SPECIFICATION forming part of Letters Patent No. 634,230, dated October 3, 1899.
Application ledfMay l, 18979, vSerial N0- '7l5,204. (No model.)
To all whom it may concern.-
Be it known that I, ALBERT' STANLEY DIXON, of Escondido, in the county of San Diego and State of California, have invented new and useful Improvements in Conduit- Pipes, of which the following is a specification.
My invention relates to pipe for use for conducting` water and other fluids, and is also adapted for electrical conduits and the like.
In my invention I employ a binding substance-,and it is to be understood that the pipe is not to be used with any fiuid which would attack the binding substance. For example, where the binding substance is asphaltum such binding substance would be attacked by petroleum, and therefore the pipe with such a binder would not be iitted for conducting petroleum-oils, although the pipe in which such binding substance was used would serve perfectly for conducting water and also for electrical conduits.
The object of my invention is to provide a cheap, light, strong, durable, and rigid pipe at a minimum expense.
My newly-invented pipe is composed of a iiexible sheet wound upon itself with a binding material and an interposed metallic winding. The iiexible sheet is preferably paper and the same is preferably thoroughly saturated with the binding material, the base of which is asphaltum, maltha, or the like, together with any suitable tempering materialsuch as sulfur, for example-and the interposed metallic win'din g may be made of metal strips or Wires and the same being wholly interposed between the layers of paper, so that no part of the metallic winding is exposedv to corrosion.
My invention is applicable in various ways.
The accompanying drawings illustrate my invention.V
Figure l is a fragmental perspective View of a section of pipe embodying my invention. Portions of the flexible sheet are broken and raised to expose the metallic winding and to illustrate the structure of the pipe. Fig. 2 -is an exaggerated fragmental longitudinal section of the same. Fig. 3 is a cross-section on y line 3 3, Fig. 2. Fig. 4 is a fragmental detail of paper and wire aft-er the strands have Vbeen Wound once around according to one form of 'wimlinga` Fig. 5 is a like view indieating another form of winding. Fig. 6 is a cross-sectional view showing the pipe paper and wire on rolls in the process of manufacture.
A indicates the pipe, composed of a rectangular sheet of paper (indicated at l) wound upon itself, with a binding material2 interposed between the layers of paper and saturating the paper to form an inner shell 3, and further Wound upon itself outside said inner shell, with metallic strands or Wires 4 interposed between the layers, together with the binding material, to form a stiffening and strengthening intermediate portion 5, said paper being further wound upon itself outside of said intermediate portion 5, with a binder interposed to form an exterior shell 6.
In manufacturing the pipe the same will be made from a continuous roll of paper, and said paper will be wound upon a mandrel M, which is arranged parallel with the axis of the paper roll P` so that the width of the paper makes the length of the pipe-section.
R indicates a roller to apply the required pressure. lThe paper is to be passed through a bath of the liquid binding material (not shown) before being wound and pressed into the pipe. The metallic strands will be composed of a plurality of metal wires, which are preferably circular in cross-section, arranged at a preferred distance apart-for example, say from one-half inch to an inch and a half. Where round wire is used, No. 2O .will be found very efficient for pipes to withstand a strain of one hundred pounds to the square inch expansive force, the paper or other flexible sheet being of a suitable texture and of a sufficient weight to give the desired body to the pipe when combined with the binding material, as stated. The interior shell 3 is made thick enough to hold the wires in place when the same are Woundin between and the outer layers of the paper or other iiexible sheet, and the strands may be wound around one or more times before being cut oif. After the strengthening portion or body 5 has been formed the strands are out off, and the winding is continued until au .exterior shell 6 of sufficient thickness to hold and protect the wires is formed.
In practice while the strands are beinginclosed between the layers of paper they hold the roller R away from the mandrel, so that the layer of binding material between the strands and between the layers of paper will be equal in thickness to the diameter of the strands, thus forming a convolute body of the filling material of a considerable thickness, thereby adding to the strength and the impermeabilityofthepipe. Thisfllingwhen hardened will prevent any displacement of the strands. During the process of lnanufacture the pipe is forcibly compressed in order to condense the pipe and form a perfect binding between the layers. Vhen the winding and com pression have been com pleted, the section is removed from the mandrel and is ready for use. Preferably the section thus made is treated t0 a bath of the binding material before use.
Now, having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
A pipe composed of a sheet of paper Wound upon itself with a binding material between the layers to form an inner shell, and further wound upon itself outside said inner shell with metallic strands interposed between the layers together with a binding material to form a stiifening and strengthening intermediate portion, said paperbeing further wound upon itself outside 0f said intermediate portion with a binder interposed to form an exterior shell.
ALBERT STANLEY DIXON.
