The object of our invention is'to provide 'ai flexible metallic sheathing or' casing for iieX'i-v ble tubes, dac. ,in order to increase the strength ofthe article incased either against tensile strains in the case of tubes or ropes, against ropes, dac. .c

A further Object of our invention is to provide a coupling for'r'opes Y'or tubes, as fully described hereinafter.

Referring to the accompanying drawings,

Fig. 2 is a transverse sectional view.- Fig. 3

is a view showing the method of applying the sheathing to the article tO-be incased; Fig l 4 is a View showing the casing applied to the:

outside of a rubber hose. Fig. 5 is a view showing the casing applied to the inside of a rubber hose. Fig. 6 is a View showing the casing applied `to'y a rope. showing the method of applying the sheathing in splicingropes so asto forma coupling. Fig. Sis a View showing the sheathingapplied as a tube-coupling. Y

In the manufacture of our improved casing A we take a number ofends of tempered at steel wire a, preferably galvanized to lprevent corrosion, and braid this wire to tubular'form, as shown in Figs. l and 2, the mesh being determined during the process of braiding, and We preferably braid the tubes to be applied to objects from Vone-half 'an inch to three vinches of one diameter, and by changing the to the tube, as shown in Fig. 3.

ing is then drawn down upon the hose, either Fig. 7 is a viewsional strain on the tube after it is made the diameter will be decreased, and by placinga compressing strain on the end of the vtube the diameter will be increased.

The article, as shown in Figs. l and 2, is itself a complete article of manufacture and is now sold by us to be applied to tubing, rope, cbc., in any length required, and we usuallywrap the sheathing upon reels holding one thousand feet, and this sheathing can be cut off in lengths as required.

To Vapply the sheathing A to a rubber or other hose B, we'cut the sheathing the proper length, 'compress it longitudinally, so as to increase itsdiameter in. order that it Inay be slipped readilyover the hose to be incased, and after it is in position one end of, the sheathing is secured to the hose or other tubing in any suitable manner, preferably by Wrappingnesoftimaround ,the sheathing and tube, so asy to tightly bind the sheathing The sheaththrough the hands or by means of a tool, so that its length will be increased, and consequently its diameter decreased, until it Iits perfectly tight upon the hose, as shown in vFig-4, after which the'free end is secured to rated points of attachment and is free to eX- pand 'and contract between said points of attachment'when the said article is bent.

Where an ordinary hose-coupling C is used,

the clamp for securing the' hose rto the coupling may be applied over the sheathing, so as to hold the sheathing firmly to the tube and the tube to the coupling.

In inoasing tubes with couplings attachedsuch, for instance, as the'tubes 'oiakbrad mechanism of railway-cars-allthat is necessary is to longitudinally contract the sheathing, so that it will readily slip'over the head of the coupling, as Well as over the hose,` after which it is fastened at one end and drawn out until it binds tightly upon the hose, and then fastened tightly at the opposite end either by a clamp or other means of fastening.

IOO

XVe have submitted hose incased with our improved sheathing to severe tests, and it has withstood pressures up to one thousand pounds to the square inch.

The ilatwire presents a sufficient surface to prevent the cutting of the tube by the wire, and the braiding is open sufficiently to allow the tube the same free movement as it the sheathing was not applied. Furthermore, a tube with the easing applied will not buckle or kink and in time crack, as will the tube not provided with a easing.

In Fig. 5 we have shown the sheathing A applied to the inside of a tube I3 instead of the outside where it is wished to resist atmospheric pressures, and in order to apply the sheathing` to the tube we stretch the sheathing so that the diameter is less than the internal diameter ot the tube. lVe then slip the sheathing into the tube and increase its diameter by longitudinal compression until it lits tightly against the tube, when it is fastened at each end.

Fig. t3 is a view illustrating the sheathing A applied to a rope D, and may be either applied to ordinary liber rope or wire rope. lly applying this sheathing to the rope we find that the strength is materially increased, the strands are coniined closely together, thus preventing fraying, and, furthermore, when the rope is used in a winding-drum, for instance, the sheathing prevents chating.

The sheathingbeing braided allows for the free contraction ot the rope when wet and expansion of the rope when dry, and it will allow Ithe rope to swell, yet will keep ittaut at all times, the flat surface of the wire preventing cutting, the-same as described above in connection with the rubber hose.

XVe may use the tube as a means of coupling together two pieces of rope or two sections of hose. For instance, as shown in Fig. 7, some of the strands of one section of rope may be eut baek some distance from the end of the section and some of the strands ot' the other section may also be cut baek of the end and the loose strands twisted together, so as to form a joint of an even diameter without resort-in g to the ordinary method of splicing. Previous to joining the ends of the rope together our improved sheathing is slipped over one section, so that when the sections are wrapped together by drawing the sheathing over the joint and pulling it out, so that it will bind tightly upon the rope, and securing it to the rope at the ends we are enabled to tightly bind the uncut strands of rope together, and the more strain that is placed npon the rope the tighter the strands will bind, so that we not only rely upon the tensile strength of the sheathing, but also upon its quality to hold the strands of rope in frictional contact.

Hose or tubing maybe coupled in the manner shown in Fig. S by inserting in the ends of the two sections to be joined a tubular coupling-section, and by slipping a short seetion of our improved sheathing over the tubes at the joint and stretching it, so as to tightly grasp the tubes at the joint, we are enabled to make a joint that is strong and which will withstand more than the ordinary pressures.

llt will be understood that it it is wished the tube with the sheathing may be inclosed in an outer casing of flexible material, although we have found that by galvanizing the wire corrosion is prevented and the inclosing casing may be dispensed with.

Te prefer to use a tlat wire, because it can be used without any such tendency to eut into the article to which it is applied as may in some eases exist where a round wire is used; but a round wire maybe used in solne cases, and it will be understood that we do not limit ourselves to a flat wire.

lVe claim as our inventionl. Thecombinationotallexibleartiele,such as a hose, rope, the., a sheathing composed of a series of tlat wires braided or interlaced, said sheathing being secured to the finished lleXible article at separated points of attachment, and being tree to expand and contract between said points of attachment when the iiexible article is bent, substantially as described. l

2. The combination of a tinished tube, a sheathing made of a series of [lat wires braided into the torni of a tube, said sheathingbeing slipped over the tinished tube so as to snugly iit thereon, with means for securing the wires forming the sheathing to the tube at separated points ol attachment so that the wires will have free movement between the points ot attachment when the tube is bent, substantially as described.

ln testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
