LEMUEL P. DODGE, OF NEW YORK, N. Y., ASSIGNOR TO HENRY WHITEHEAD, OF NEW YORK, N. Y.
PAPER CONDUIT.
SPECIFICATION forming part of Letters Patent No. 713,560, dated November 1 1, 1902. Original application filed December 26, 1901, Serial No. 87,298. Divided and this application filed April 1, 1902. Serial To all whom it may concern:
- Be it known that I, LEMUEL P. DODGE, a
- otherwise.
citizen of the United States, residing in New York, borough of Manhattan, in the county of New York and State of New York, have invented certain new and useful Improvements in Paper Conduits, of which the following is a specification.
This invention relates to paper tubing, and is a division of my application filed December 26, 1901, Serial No. 87,298.
In the accompanying drawings, Figure 1 is a transverse section taken on the line a: a: of Fig. 2. Fig. 2 shows one method of crimping paper or other material upon a helical wire form so as to produce a rugose or-plaited tube. Fig. 3 shows a thin coating or layer of an impervious mixture or proofing material applied. Fig. 4 is a cross-section taken at the. line y yof Fig. 2. Fig. 5 shows a plain papefconduit-that is, one not reinforced by a wire or other form. Fig. 6 shows how the product readily lends itself to flexure.
In the several viewssimilar parts are desig: nated by similar characters of reference.
In the preferred mode of practicing my invention I employ a-helical wire form 20, over or upon which I place or roll a tubing 21 of paper, preferably manila-rope paper. This is preferably wrapped in several plies, three plies being shown in this instance. The-plies may be loosely wrapped, and the outer edge may be coated with glue, as indicated at 22, or
This paper tube is loose upon the helix 20, its internal diameter being by preference materially in excess of that of the helix, as clearly seen at- Fig. 4. By suitable meansI tuck or crimp the material of the tube 21 between the whirls or ribs of the form 20. I find it advantageous first to dampen or moisten the paper, so as to render it limp or plastic, thereby enabling it to crimp with facility and without injury and also causing it to acquire a permanent set in its crimped form. One way of crimping the material is illus trated at Fig. 2, in which it will be seen that a core 23 may be wound over the tube with snflicient tightness to sink or crowd the material between the ribs of the form, the wind-' (No model.)
that the crimps be of the kind herein illus- The object in making the tube 21 of trated.
extra diameter is to furnish material for the depressed portions or flutes 24 of the corrugations, or, in other words, to enable said flutes to be formed without danger of tearing the fabric. As the formingof the conduit progresses the material of. the tube 21 is used up in longitudinal direction,so thatit is necessary for the original length thereof to be greater than that of the finished conduit. The paper when being tucked into the crevices between the wires is also caused to shirr or wrinkle, as at 25. The conduit or tube thus formed may be used for a variety of purposes and possesses many valuable qualities, being highly flexible, capable of elongation or contraction, strong, durable, and simple, and, moreover, it may be constructed of inexpensive material in a simple manner and with great expedition and at low labor cost.
In the production of gas-tubing I preferably treat the Fig. 2 product with a coating 26 of material impervious to gas, such as a compound "of glue or glycerin. Preferably the material is applied with substantially even thickness over the plaits of the tubing, as clearly seen at Fig. 3, so that in the Fig. 3 product the fine 'wrinkles or shirrs 25 are somewhat filled up or evened by the material 26, which may be applied thereto in a heated liquid form and then allowed to dry or cool and harden. The paper, it will be understood, forms a backing or body which is both inexpensive and also well adapted for receiving and protecting from injury the gas-proof material 26. formed, owing to the corrugated or rugose formation of the gas-proof material, is rendered far more flexible than heretofore and may be also drawn out or compressed endwise without injury. Owing to this formation,.neither the gas-proof coating nor the paper is liable to take a permanent set when 9 Moreover, the tubing thus maintained for a long time ina flexed condition, thereby overcoming or, at least, minimizing a common fault in gas-tubing My tubing is therefore more durable and superior than prior tubing and is also adapted for use in a variety'of ways not hitherto found practicable. I prefer to use manila-rope paper for the tubing, since 'it absorbs little or none of the proofing material. In fact, the paper itself is almost impervious to gas, and hence only a thin wash of proofing material is required. The proofing may be otherwise applied than as a-coating.
Fig. 6 illustrates the facility with which the product may be flexed, whether having a form 20 or not, the plaits at theouter portion of the bend separating, as at A, and those at the inner portion of the bend crowding together, as at B, this result being effected without appreciable tendency to injure either the fabric or the proofing and without rendering either of them liable to acquire a permanent set.
At Fig. 5' is illustrated my crimped or corrugated tubing without a wire form. Such tubing may be produced either by the Fig. 2
method, after which the wire helix may be wormed out, or it may be otherwise formed without departing from my invention. In other words, although I show my flexible paper or papery-fabric tubing 21 as used in connection with the wire form upon which it is made, still it may be otherwise made or it may be used without any wire or other form within the scope of my improvements.
Having described my invention, I claim- 1. A paper tubular limber conduit having transverse plaits for rendering it limber and extensible.
2. A tubular paper limber conduit crimped into the form of a longitudinal succession of plaits so as to render it firm, limber and ex-' tensible.

10. A limber conduit consisting of paper rolled into tubular form and reduced in diameter by helical crimps.
