` Specification of Letters Patent. Patented Aug. 28, 1917.
Application filed December 14,1915. Serial No. 66,874.
To all 'whom t may concern.'
Be it known that I, MAURICE BLUMEN- THAL, a citizen of the United States, and resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Con-A duit-Joint Wrappers, of which the following is a specification.
This invention relates to wrappers for the joints of conduits such as are used under ground as ducts for electrical conductors and analogous purposes, and it has for its object to provide a simple and improved wrapper for this purpose which will maintain a perfect fit completely around the conduit, which will be permanently adhesive with relation thereto, which will be absolutely water and acid proof, and which 'will furthermore possess advantages in convenience of application, inexpensiveness, effectiveness, and general eiiiciency.
In the drawings-- Figure l is a plan view of a portion of the fabric base of the improved wrapper.
Fig. 2 is a plan view of the reverse side of the fabric base as shown in Fig. l.
Fig. 3 is a plan view. of a portion of the wrapper in its completed condition ready for use.
Fig. 4 is a plan view of the reverse side of the wrapper in completed condition as shown in Fig. 3.
Fig. 5 is a side view illustrating a conduit joint with the improved wrapper in position thereon and partly broken away to show the relative construction. j
Fig. 6 is a transverse sectional view across a conduit at the joint portion and showing the improved wrapper 1n position thereon.`
Corresponding parts in all the figures are denoted by the same reference characters.
Conduite of the construction to which my improved wrapper particularly relates vare usually formed of vitrifiedclay, but it will be understood that the wrapper is adapted for eEective service conditions with relation to conduits of any material and under various conditions of use.
V Referring to the drawings, 1-1 designate the conduit sections, which are laid with their end edges closely abuttingand' forming a joint, as at 2. My improved wrapper is constructed insuitab'le strips or lengths, which may be rolled and fed from a reel in commercial usage and out into sections of the desired length to be wrapped around the conduit joints.
The improved wrapper comprises a fabric or textile base, 3, which in the preferred construction consists of a strong twine interwoven as warp and woof threads, as shown at 4, with an open mesh, as shown at \5, and having a facing at one surface, as
shown at 6, covering the twine and closing the mesh. The facing is preferably constituted by a pulp applied to the textile fabric, but it may be of any other suitable character or material. While I have illustrated the preferred type of the fabric base of the wrapper, as above described, under some conditions of use the textile base may be employed without the facing 6, or the openmesh fabric may be flattened in rolls to spread the threads and reduce or close up thewopen mesh, or the fabric may be closely woven or be of any suitable weave with or without the facing 6, as willy be readily understood. `It is of course essential that the fabric be of strong character adapted to the effective purpose in which the wrapper is employed and be of suiiiciently pliable nature to enable its convenient application to the conduit joint in the manner hereinafter set forth.
The fabric or textile base 3 carries throughout its body and over its surfaces a filler, shown at 7, which is water and acid proof and thoroughly impregnates the fabric, and which is permanently of a tacky or adhesive character whereby the entire surface and body mass of the wrapper has permanently the characteristics just stated.
The filler 7 which thoroughly impregnates the body of the wrapper and is carried by the fabric or textile base thereof, is constituted by a suitable compound which in its constituents afords'the impervious and permanently adhesive or tacky characteristics above mentioned. The preferred filler element of the wrapper is constituted by animal or vegetable fats or oils combined with mineral waxes, such as ozocerite, mineral caoutchouc, gilsonite, or retinite, the compound having a melting point approximately as high as 37 5 F.
n In practice, the filler is combined with the fabric or textile base by any suitable method. In the preferred method of constructing the improved wrapper, the fabric or textile base 3 is passed in a continuous strip through a bath constituted by the filler compound 7 in solution at the desired melting point, whereby the fabric base is thoroughly impregnated with and covered at all its surfaces by the liller compound. The impregnated strip, after subjection to the bath, may then be rolled or reeled incondition for commercial use, and under the characteristics of the filler compound has a permanently adhesive or tacky surface condition which will not be impaired by the exposures incident to the general handling and usage of the wrapper.
In Figs. 5 and 6 I have illustrated the method of applying my improved wrapper to a conduit joint. After the conduit sections 1-1 are abutted together at the joint 2, it is simply necessary to draw the Wrapper strip, shown at 8, having the construction and characteristics according to my invention, around the conduit joint so that it completely covers and incloses the same, and
in this application of drawing the wrapper around the joint the permanently adhesive ortacky characteristics thereof will cause the wrapper to positively and effectively adhere to the surface of the conduit at all points of contact therewith. The ends of the wrapper strip 8 are preferably overlapped a suitable distance, say, about 3 inches, and the overlapped portions are pressed together, thus effecting a tight and permanent adhesion between the overlapped ends of the strip and maintaining the drawn length of the wrapper in a snug and permanently adhesive ft completely around the conduit. The impervious and permanently adhesive characteristics of the wrapper thus produce an absolutely water and acid proof closure of the conduit joint, which is ermanently maintained by the inherent c aracter of the wrapper itself, and the cement surfacing which is usuall placed over the joint wrappers of conduits therefore does not affect the water-proof conditions butthe y cement surfacing over the wrapper effectively co-acts with the characteristics thereof and is adapted to perfectly adhere to the wrapper, by reason of the rough texture of the fabric or textile body thereof, thus roducing enhanced joint conditions in which there is no possibility of leakage of ycement or water into the conduit joint.
The operation and advantages of my ini,aes,eee
vention and improvements will be readily understood by those skilled in the art to which they appertain. The improved Wrapi per is not only of simple and inexpensive construction andv capable of convenient application, in contradistinction to the joint closures or wrappers which have heretofore generally. been employed, but it provides an absolutely water-proof covering at all points of the conduit joint and maintains a permanent adhesion and close adherence to the conduit surface at all points throughout the area of the wrapper.
I do not desire to be understood as limiting myself to the detail features of construction as herein shown and described, as it is manifest that variations and modifications therein may be resorted to, in the adaptation of my invention to varying conditions of use, without departing from the spirit and scope of my invention and img5 provements. I therefore reserve the right to all vsuch variations and modifications as properly fall within the scope of my invention and the terms ofthe following claims.
Having thus described my invention, I claim and desire to secure by Letters Patent:
l. An improved conduit-joint wrapper constituted by a flexible strip comprising a fabric or textile base having interwoven warp and woof threads with an open mesh and a facing covering the threads and closing the mesh and a' body compound impregnating the textile base and facing and covering the entire surface thereof and having 10c a permanently water-proof and adhesive character.
2. A conduit-joint wrapper consistin of a flexible strip having a fabric or textile ase carrying a body compound impregnating the textile base and covering the entire surface thereof and having permanently waterproof and adhesive character which isimparted to land inherently and permanently maintained by the wrapper.
3. A conduit-joint, consisting, in combination with the conduit sections, of a flexible strip drawn completely around the joint and constituted by a fabric or textile base carrying a body compound impregnating the textile base and filling the mesh and covering the entire surface thereof and of ermanently water-proof and adhesive c aracter, said wrapper strip having a permanent adhesion to the surface of the conduit sections at all points of contactttherewith.
4. A conduit-joint2 consisting, 1n combination with the conduit sections, of a flexible strip drawn completely around the joint and having its ends overlapped, said wrapper strip being constituted by a fabric or textile base carrying a body compound iinpregnating the textile base and filling the maeee mesh and covering the entire surface thereof and of permanently Water-proof and adhesive character, whereby the body of the Wrapper strip has a permanent adhesion to lthe surface of the conduit sections at al1 points of contact therewith anda permanent adhesion at the overlapped ends of the strip to maintain the drawn length of wra per in a snugl and permanently adhesive t completely around the conduit.
In testimonyl whereof foregoing specification.
MAURICE BLUMENTHAL.
