Improvements in Machinery for the Manufacture of Hose or Tubing.
I, JAMES LIONEL JONES, of 15, Parliament Street, Dublin, Ireland, Hose Manu-
facturer, do hereby declare the nature of this invention to be as follows:-
This invention has for its object improvements in machinery for the manufac-
wire-bound" and which
ture of hose or tubing, especially for that class known as
is made up briefly as follows:
..
An internal spiral wire body is formed on a mandrel and is covered with one
or more layers or plyes of suitably prepared textile fabric, or other suitable
material, thus producing a loosely rolled up hose or tube which is then gradually
smoothed and tightened round the spiral body (preferably by hand) throughout
its length.
When so prepared this covering is bound externally with a spiral binding of
wire or cord, or other suitable ligature, the convolutions accommodating themselves
to the spaces or intervals formed between the convolutions of the internal spiral
body.
In carrying out my invention I propose to use steel or other mandrels on which
to form the spiral body wire, and my method is as follows:-
I cause the mandrel to revolve in suitable bearings whereby it is free to move
in the direction of its length, and against a head through which the wire runs,
being first threaded into one of the two holes drilled near the end on the mandrel.
The head arranged to slide towards, or from the mandrel and is provided with
an adjustable removable guage, the object of which is to space the wire as it is
being spun on to the mandrel..
This gauge is adjusted by set screws whereby it can readily be thrown to right
or left for the purpose of making a spiral of coarser or finer pitch as may be
desired, or the same result may be obtained from fixed guages of different thick-
ness.
When the head with the guage is withdrawn the convolutions of wire are
laid up side by side, or in close contact, so as to form a collar which is necessary
in the larger sizes of hose or tubing to constitute a terminal end, for the reception
of couplings or connections.
The body wire being thus prepared, the free end of the termina collar, is
soldered or otherwise secured to the mandrel, whereby the wire spirals are held
firmly in contact with the mandrel throughout its entire length.
The prepared textile or other covering is now rolled round the spiral wire body
evenly and smoothly, being tied at intervals to prevent looseing, after which an
external wire is spun round the exterior, from an overhead traveller which moves
longitudinally over the mandrel, care being taken to lay the convolutions exactly
in the spaces between the spirals of the inner wire body.
The traveller may be actuated by hand, or by rack and pinion, or by other
11

tubing drawn off the mandrel by a device known as as taker off" or other suit-
able contrivance.

Improvements in Machinery for the Manufacture of Hose or Tubing.
I, JAMES LIONEL JONES, of 15, Parliament Street, Dublin, Ireland, Hose Manu-
facturer, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:
This invention has for its object improvements in the manufacture of wire-
bound hose or tubing, and in machinery therefor.
The class of hose or tubing in question is usually manufactured or made up
briefly as follows:-
An internal spiral wire body is first formed on a mandrel and is covered with
one or more layers or plyes of suitably prepared textile fabric, thus producing a
loosely rolled up hose or tube which is then gradually smoothed and tightened
round the spiral body (preferably by hand) throughout its length.
When so prepared this covering is bound externally with a spiral binding of
wire, or cord, or other suitable ligature, the convolutions of which are intended
to accommodate themselves to the internals between the convolutions of the
internal spiral body.
Now in the operation of applying this external wire binding considerable
difficulty is experienced owing to the tendency of the convolutions of the internal
body wire to become displaced or disturbed.
This tendency it will be understood is mainly due to the pressure of the external
convolutions which has the effect of pressing forward the internal convolutions,
especially when approaching the end of a length of hose, thus producing what
is known as "bunching" and consequently impairing the quality of the manu-
factured article.
Now my invention is designed to obviate this defect, as well as to produce
efficient machinery for the manufacture generally of the hose or tubing under
consideration.
Reference to the accompanying drawings will enable the nature and operation
of my said invention to be more readily understood.
Fig. 1 is a longitudinal elevation shewing the essential features of the machinery
whereby I carry out my invention.
Fig. 2 is an end view of same from the left hand side in the direction of the
arrow.
Fig. 3 is an opposite end view.
Fig. 4 is a plan of the travelling head shewing the mechanism for operating
same as presently described.

page_text: Fig. 5 is a detail view shewing the front of the travelling head and adjustable
gauge.
Similar letters indicate corresponding parts in the several views.
A indicates the frame of the machine, A' is a mandrel which revolves in bearing
blocks A2, whereby it is free to move in the direction of its length, A³ is a travel-
ling support to accommodate the length of mandrel when starting the operation
of winding. At right angles to the mandrel works a travelling head B, which is
pivoted through a slot in the plate C, (Fig. 4) to the lever a which has a movable
fulcrum band is controlled by the screw e the latter being worked by the lever
handle d.
So far it will be obvious the head is capable of being moved to and from the
mandrel within a certain limited space and this limited space may be altered
by moving the fulcrum 6 which operation is effected by the winged nut e acting
on the spindle f embraced by the spiral spring f¹ working against fixed bearing, f
and collar f
In the front of this head is an adjustable gauge g (Fig. 5) which consists of a
vertical rod oscillating on its lower end, and supported on either side by set
screws h, h by the operation of which the gauge may be thrown into various angles
whereby the spacing of the wire is regulated as it is being spun on to the mandrel.
It will be understood that this gauge being almost in contact with the mandrel,
by altering its inclination from the perpendicular, the space between the convolu-
tions of wire can readily be regulated, and thus a spiral of coarser or finer pitch
produced as may be desired.
It is obvious that the same result may be attained by fixed gauges of different
thicknesses, but I prefer to use the oscillating gauge as described.
The wire used in the manufacture of the hose or tubing is led from a convenient
source over the pulley i of the travelling head and passing to the face of the head
is received on the mandrel, where it is laid up side by side in close contact to form
a rigid collar or terminal.
Having wound the necessary length of spiral body, the travelling head is with-
drawn by the operation of the handle d and the wire is again laid up side by side,
in close contact, so as to form a rigid collar which with the collar formed at the
starting of the spiral constitute terminal ends, to facilitate the reception of
couplings or connections.
Here it is that an essential feature of my invention is manifest, for instead of
allowing the cut end of the wire to lie freely I secure it to the mandrel by solder
or otherwise, and thus prevent any tendency to uncoil, and ensure that each con-
volution shall be held firmly in contact with the mandrel and in its proper place
throughout its entire length during the subsequent operations of manufacturing
the complete article.
The prepared textile fabric is now laid over this spiral body evenly, and
smoothly, after which the external wire is spun round the exterior, from an over-
head traveller D, being carried round the train of pulleys as shewn whereby its
tension is adjusted.
The traveller which is hung from the frame A, of the machine is moved longi-
tudinally over the mandrel by means of a cord K fixed to any convenient position
to the right of the machine and brought over the pulley K¹ which is operated by
a handle K³.
The prolonged arm is provided with a sliding plate which abuts against, and
prevents the mandrel rising during the operation of laying on the external
winding.
During this latter operation (external winding) the advantage of my invention
is obvious (namely the securing of the free end of the internal spiral to the
mandrel) for owing to the tension of the external wire, each convolution exercises
a tendency to press the internal convolutions out of place, thus producing what
is termed "grouping or bunching" " and interfering with the proper manufac-
ture of the hose or tubing.

page_text: According to my invention however the internal spirals cannot move even
under the heaviest pressure produced by the external binding owing to the
soldering of the free end in the manner described
The external wire like the internal wire is finished with a terminal of closely
laid up spirals, the final end being soldered to its neighbour to form a terminal
collar.
When the hose or tubing is thus prepared, the end of the internal spiral body
(which was soldered to the mandrel) is detached and the manufactured article
drawn off the mandrel by a device known as a take off" or by other suitable
means..
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is;-
First: In the manufacture of wire bound hose or tubing the securing of the
free end of the internal spiral body to the mandrel whereby the convolutions along
the entire length are caused to retain their proper position during the manufac-
ture of the said hose or tubing substantially in the manner as herein described.
Second In the manufacture of wire bound hose or tubing, the combination of
parts consisting of a rotating mandrel A, an internal wire feeding travelling
head B, and an external wire binding overhead traveller D, all constructed,
arranged, and operating in the manner substantially as herein specified and illus-
trated in the accompanying drawings.
Third: In combination with wire bound hose or tubing the use and application
of a travelling head B, constructed, arranged and operating in the manner sub-
stantially as herein described and illustrated in the accompanying drawings.
