We, ROBERT KELSO and MORRIS ROSENBAUM, both of 254 South Second Street,
Philadelphia, in the County of Philadelphia, and State of Pennsylvania, United States
of America, Gentlemen, do hereby declare the nature of this invention, and in what
mannor the same is to be performed, to be particularly described and ascertained in
and by the following statement, reforenco being had to the accompanying
drawing, and to letters of reference marked thereon, which form a part of this
specification
--
This invention relates to a new and useful improvement in hose or other flexible
tubing, and has for its object to so construct articles of this description as to greatly
increase their powor of resisting internal strains, and at the same time prevent
kinking which is so common in fire hose, and under some circumstances causes
such serious results.
With these ends in view, this invention consists in the details of construction and
combinations of elements hereinafter sot forth and thon specifically designated by
the claims.
In order that those skilled in the art to which this invention appertains may
understand how to make and use the same, the construction and operation will now
be described in detail, referring to the accompanying drawing forming a part of this
specification, in which-
Fig. 1, is a detail view of the interlaced metallic tubing which we utilize in
carrying out our invention;
Fig. 2, a similar view, a portion of the hose or other tubing placed within the
interlaced metallic tubing, and
Fig. 3, a view showing the section of completed hose or other tubing, the section in
which the outer covering is reinoved showing the interlaced metallic tubing and the
inner tubing, and a further section of the interlaced metallic tubing without either
the inner or the outer sections of the hose applied thereto.
n
In carrying out our invention as here embodied, we utilize a hose or flexible
tubing of any suitable construction; as for instance, an inner layor A of rubber, a
layer B of fabric surrounding the first named layer, and a layer of any suitable
material, and around this hose we place an interlaced flexible metallic tubo, preferably
composed of a series of strips D, and these strips are preferably made of resilient steel
of such a thickness as to be bent in any direction, and at the same time baving sufficient
resisting power to return the boso to its normal cross section when external pressure
has been removed therefrom. Around this metal tubing may be placed a suitable
covering E of any suitable material, such as rubber or rubber coated fabric, by which
means a smooth outer surface is presented.
The meshes in the metal tubing may bo varied to suit the requirements of the
partionlar hose in which it is ntilized, and the smaller the mesh the more strength
this tubing will possess; and yet it is obvious that the strips of the tubing being free
to move upon themselves by being interlaced, as shown, the hose may be bent to a
certain degree, as freely as those of ordinary construction.
.
Should at any time external pressure be exerted upon the hose, tending to collapse
the same, the metallic tubing will spring inward, and when this pressure is removed
will again spring outward, restoring the hose to its normal cross section.

page_text: By experiment it has been found that a hose covered with our improvement
will withstand many times the internal prossure either hydraulic, steam or air,
that a hose of any construction having the same weight of material therein is
capable of standing.
Among the advantages of our improvement is that a hose thus covered when
utilized for hydraulic, steam or air purposes will not kink, thus avoiding the
cutting off of the flow of water which sometimes occasions serions results.
For ordinary purposes a hose covored with our improvement may be formed of
much thinner material than would otherwise be necessary, since the interlaced
metallic tubing will resist internal as woll as external strain, and the remaining
layers of tho lose need only be sufficient to retain water or other liquid flowing
therethrough.
If found desirable, for certain purposes the outer covering E may be omitted
without affecting the gist of our invention.
It is obvious that our improvement may be applied to a hose or other tubing which
has already been manufactured, by simply drawing the inetallic interlaced tubing
thereover, after, which said metallic tubing will serve all the purposes just described
in connection with a hose to which it has been applied in the course of
manufacture.
It is also obvious that our improvement may be applied to a tire for
bicycles and the like, and when so used will prevent the collapsing of the
pneumatic tiro even though the same be punctured and the air permitted to
escape therefrom, as the pnoumatic tubing will serve as a support and expander for
the tire.
Having now particularly described and ascertained the naturo of our said inven-
tion and in what manner the same is to be performed, we declare that what wo
claim, is-
1. An interlaced metallic tubing to be used as a cover for hose or tubing of any
manufacture to retain liquid or gas.
2. As a new article of manufacture, a hose or other flexible tubing consisting
of suitable liquid-retaining layers, and interwoven strips surrounding said layers,
as specified.
3. As a now article of manufacture, a covering for a hose and the like consisting
of a series of flexible motallic strips interwoven around said hose so as to bend
therewith.
4. A series of flexible strips interwoven around a hose, and a suitable covoring
surrounding said strips, substantially as shown and described.
