Improved Methods of and Apparatus for Making Seamless Rubber
Lined Hose.
I ERNEST NATHANIEL FOOTE of 1641 East Madison Avenue Cleveland Ohio
United States of America Rubber Worker do hereby declare the nature of this
invention to be as follows:
--
My invention relates to improved methods of and apparatus for placing a
seamless rubber tube or a tube made of analogous material used in the manufacture
of hose on a pole or metal arbor of any required length while undergoing the
process of manufacture.
Heretofore owing to the soft gummy elastic and adhesive nature of the rubber
compound used in lining hose it has been found practically impossible to draw or
force onto a pole or arbor a seamless rubber tube while it is still fresh from the
tubing machine or even a cured or partially vulcanized tube.
By the common or ordinary methods of manufacture the rubber compound for
making a tube is first made into a sheet-by means of a calendering machine-of
the desired length and thickness. It is then cut into strips of proper length and.
width and placed on a long table. The upper sides or faces of the strips are then
dusted or powdered with soap stone to prevent the adhesion of the pole or metal arbor
during the process of vulcanization. Said pole is then placed longitudinally in
the centre of said strips and the side of the same is folded or wrapped over it the
edges of the material being either butted or lapped together and smoothed and
pressed down by a hand tool.
It will be seen that the tube thus formed is secured firmly to the pole throughout
its entire length and circumference. The pole together with the tube secured
thereon is then passed to a wrapping machine and covered with cloth duck or
canvas until the desired number of ply or covering is rolled thereon. It then
passes to the vulcanizer or heater where it is subjected to heat until cured when it
is removed from the vulcanizer and the hose thus made is ready to be taken from
the poles.
By my invention I am enabled to insert the pole within a seamless fresh tube. or
in other words draw a seamless tube over the pole. The seamless tubing is forced
from the die and deposited on a-belt. The required length having been passed out
the tubing is cut off and a knot is tied in the back end of the tubing or the
tubing otherwise closed at one end.
The interior length of the tube is soap stoned or dusted with soap stone in any
suitable manner to prevent adhesion of the tube to the pole. A metal arbor is
provided in line with the tube to be drawn thereon and the tube is placed on a
movable support or carrier. The end of the arbor is then introduced into the
tube and the carrier mechanism is put in operation moving the tube onto the pole
as the pole thus enters the tube the air confined therein becomes compressed and
immediately begins to expand the tube thus allowing a film of air to escape at the
same end at which the pole is entering thus forming a lubricant for the easy
passage of the pole and at the same time assisting it to enter the tube. The only
power required to move or draw the tube onto the arbor is the movable carrier on
which the tube is supported and the weight of the tube together with the weight of
the inserting arbor causes sufficient friction of the tube against its carrier to
overcome the slight friction of the arbor entering the tube.
In carrying out my invention tables are arranged longitudinally in front of the
tube forming mechanism said tables being respectively provided with pulleys or
wheels suitably journaled and provided with endless band or carrier mechanisms
:

page_text: respectively that pass about the respective pulleys of each table said bands are
provided with raised edges or flanges that serve to prevent the tubes or arbors
from lateral displacement while on the band. Journaled in the top of the tables
transversely to the movement of the band are a series of rollers that serve to
support the bands and prevent their sagging under the weight of the material to be
carried. Pivotal lever stop mechanism is. pivoted on one side of the middle table
and is adapted to be brought down into horizontal position in order to prevent
longitudinal movement of the arbor as the tube is being drawn on to said
arbor.
The tubing machine having been placed in operation the rubber compound or
tube is forced from the die of the same and deposited on the belt of the table that
is in proximity to the machine.
It will be understood that the belts of all the tables are connected up to any
suitable driving power and at this stage of the operation are being actuated so as
to keep pace with the tube as it is being forced from the die.
As soon as a tube has reached the required length or the length of the table on
which it is deposited it is cut off and removed from the belt to the side of the
table until a sufficient number of tubes are run. The tubes are then soap stoned
. throughout their entire length to prevent adhesion to the pole.
-
A sufficient number having been prepared a knot is then tied in the end
of the tubes nearest the tubing machine or their extremities are otherwise closed
in any suitable manner to prevent the escape of air. Power is now applied to the
belt on the middle table. The pole is deposited on said belt and is kept from
moving endwise by means of a lever stop. The opposite end of the pole is now
introduced into the end of one of the rubber tubes resting on the table nearest the
tubing machine care having first been taken to see that the said tube is filled with
air. This may be done by the workman blowing into the end of the tube. The
tube is then gently forced onto the pole a few inches by hand till it comes in
direct contact with a belt which being in motion causes the tube to slide onto the
pole automatically by reason of the weight of the tube resting on the belt and the
weight of the end of the pole pressing it downwards at the same time. As
the pole thus enters the tube the air confined therein becomes compressed and
immediately begins to expand the tube thus allowing a film of air to escape at the
same end at which the pole is being introduced thus forming a lubricant for the
easy passage of the pole and at the same time assisting it to enter the tube.
The tube having been thus forced onto the pole the operator raises a lever and
allows the pole with its rubber tube to be carried along onto the belt of the third
table which belt in turn moves it to the end of the table. It is then removed to
the wrapping machine and wrapped as herein before described.
The great utility of my invention is apparent. Lapped seam hose has always
been a source of trouble and perplexity to manufacturers. Hose so made can
never be considered perfect as the lap in the rubber sheet forming the tube is
liable not to perfectly unite the entire length and water reaches the duck.
I overcome this obstacle by running a seamless tube as described. This cannot
be penetrated by water it is invulnerable and is equally strong at all points on its
periphery.
It should be distinctly understood that I do not limit myself to the particular
mechanical forms herein described as other forms of embodying and using the
principle of my invention may be employed in substitution for the specific form
herein shown. It will therefore be understood that omissions substitutions and
changes may be made as regards the forms and parts herein set forth provided the
principles of construction previously described are embraced.

Improved Methods of and Apparatus for Making Seamless Rubber
Lined Hose.
I ERNEST NATHANIEL FOOTE of 1641 East Madison Avenue, Cleveland, Ohio,
United States of America, Rubber Worker, 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 :-
My invention relates to improved methods of and apparatus for placing a
seamless rubber tube or a tube made of analogous material used in the manu-
facture of hose on a pole or metal arbor of any required length while undergoing
the process of manufacture.
Heretofore owing to the soft gummy elastic and adhesive nature of the rubber
compound used in lining hose it has been found practically impossible to draw or

tubing machine or even a cured or partially vulcanized tube.
By the common or ordinary methods of manufacture :-the rubber compound
for making a tube is first made into a sheet by means of a calendering machine→
of the desired length and thickness. It is then cut into 'strips of proper length
and width and placed on a long table. The upper sides or faces of the strips are
then dusted or powdered with soap stone to prevent the adhesion of the pole or
metal arbor during the process of vulcanization. Said pole is then placed
longitudinally in the centre of said strips and the side of the same is folded or

in other words draw a seamless tube over the pole.
The seamless tubing is forced from the die and deposited on a belt. The
required length having been passed out the tubing is cut off and a knot is tied in
the back end of the tubing or the tubing otherwise closed at one end.
The interior length of the tube is soap stoned or dusted with soap stone in any

A metal arbor or pole is provided in line with the tube to be drawn thereon and
the tube is placed on a movable support or carrier. The end of the pole or arbor
is then introduced into the tube and the carrier mechanism is put in operation
moving the tube onto the pole or arbor; as the pole or arbor thus enters the tube
the air confined therein becomes compressed and immediately begins to expand the

tube onto the arbor is the movable carrier on which the tube is supported and the
weight of the tube together with the weight of the inserting arbor causes sufficient
friction of the tube against its carrier to overcome the slight friction of the 'arbor

respectively C C C² that pass about the respective pulleys of each table said
bands are provided with the raised edges or flanges c that serve to prevent the
tubes or arbors from lateral displacement while on the band. Journaled in the top
of the tables transversely to the movement of the band are a series of rollers c¹
that serve to support the bands and prevent their sagging under the weight of the
material to be carried. Pivotal lever stop mechanism D is pivoted on one side of
the middle table A' and is adapted to be brought down into horizontal position in
order to prevent longitudinal movement of the arbor E as the tube is being drawn
onto said arbor.
The tubing machine E' having been placed in operation the rubber compound or
tube F is forced from the die of the same and deposited on the belt of the table A
that is in proximity to the machine.
It will be understood that the belts of all the tables are connected up to any

diately begins to expand the tube thus allowing a film of air to escape at the same
end at which the pole is being introduced thus forming a lubricant for the easy
passage of the pole and at the same time assisting it to enter the tube.

and allows the pole with its rubber tube to be carried along on to the belt C² of
the third table which belt in turn moves it to the end of the table. It is then
removed to the wrapping machine and wrapped as hereinbefore described.

heen a source of trouble and perplexity to manufacturers. Hose so. made can
never be considered perfect as the lap in the rubber sheet forming the tube is
liable not to perfectly unite the entire length and water reaches the duck.
