I ALEXANDER WYLIE of the Perseverence Ironworks, Johnstone, near Glasgow,
Engineer, do hereby declare the nature of my said invention to be as follows:-
The first part of my invention consists in the construction of containers for new
lead pipe machines, or applying them to existing lead pipe machines, and for cores
for forming the inside of the pipes, and dies for forming the outside of the pipes
and relates to containers for holding lead, molten or solidified, and constructed for
the production at one operation of one, two, three, or four or more pipes, or rods,
from outlets in the sides, in a horizontal position, having cores and dies affixed
therein, all of the same or different sizes. This container is filled with lead or other
metals, and operated upon by a solid plunger, or a hollow plunger with a solid die,
either upon lead pipe presses, formed to operate upon the principle known in the
Lead trade as the upward or downward principle, producing pipes and rods of
any desired length and weight per yard.
The second part of my invention consists in the construction of containers for new
lead pipe machines, or applicable to existing lead pipe machines, and its object is
to provide an arrangement of cores and dies placed horizontally in containers of lead
pipe machines, whereby telegraph and telephone cables, and wires for electric
purposes may be covered with lead or other metallic compounds, in long lengths.
The object of the third part of my invention is to prevent injury to the insulated
covering of the cables or wires by the heat of the lead or lead container during the
process of covering.
The lead container is placed upon a resting block on the top of a water piston
or ram of the lead pipe machine or hydraulic press, in a manner similar to that
of using a lead container in making lead pipes, but a hollow block is attached to
the underside, which is constructed with water chambers, and a free circulation of
cold water is kept continually flowing, for the purpose of keeping the hollow block
cool, and preventing the cable being injured by heat. The core seat with the rings
or dies for forming the thickness of lead covering are inserted in this hollow block,
and the cores for guiding the cables or wires to be covered are screwed into position
from the outside of the container and regulated by means of screws.
The cores
for guiding the cables through the hollow block horizontally may be constructed
hollow or double cased, so as to admit of a constant free circulation of cold water
for keeping the cores cool, and preventing the cables being injured by heat.
In starting to cover cables, the hollow or double cased core is screwed up against
the ring or die, to prevent the lead passing through the side of the hollow block,
on the underside of the container; the cable is passed through this core, and when
the lead is sufficiently cold in the container, the core is unscrewed back a little, to
allow the lead or other compound to pass round the same, for the purpose of
covering the cable. Instead of passing the cable through a body of molten lead
or other compound it is only exposed to the action of the molten or solidified lead
or other compound at the point of contact.
The object of the fourth part of my invention is to cover with lead or other com-
pound, a series of cables forming insulated coverings at one operation, by means
of cores and dies, similar in construction to that described in the third part of this

page_text: Specification and for the purpose of covering any number of telegraph or telephone
cables or wires by lead pipe lining or coating by hydraulic pressure in lead pipe
machines, or hydraulic presses and containers therefor.

I ALEXANDER WYLIE of the Perseverance Iron Works, Johnstone, near Glasgow,
Engineer, do hereby declare the nature of my said invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
The first part of my invention consists in the construction of containers for new lead
pipe machines, or. applying such containers to existing lead pipe machines; and in
fixing cores for forming the inside of the pipes, and dies for forming the outside of
the pipes, and my invention relates to the construction of containers for holding lead
or metallic compounds in a molten or solidified state, and constructed for the manu-
facture, at one operation, of one, two, three, four or more pipes or rods, from outlets in
the sides in a horizontal position, having cores and dies fixed thereto, all of the same
or different sizes. This container is filled with lead or other metals, operated upon
by a solid plunger, or by a hollow plunger with a solid die upon lead pipe presses,
formed upon the principle known in the Lead trade as the upward or downward
principle, producing pipes and rods of any desired length and weight per yard.
The second part of my invention consists in the construction of containers for new
lead pipe machines, or applicable to existing lead pipe machines: and its object is to
provide an arrangement of cores and dies placed horizontally in containers of lead
pipe machines, whereby telegraph and telephone cables and wires for electric purposes
may be covered with lead or other metallic compounds in long lengths.
The object of the third part of my invention is to prevent injury to the insulated
covering of the cables or wires by the heat of the lead or lead container during the
process of covering.
The lead container is placed upon a resting block on the top of a water piston or
ram of the lead pipe machine or hydraulic press in a manner similar to that of using
a lead container in making lead pipes, but a hollow block is attached to the underside
which is constructed with water chambers and a free circulation of cold water is kept
continually flowing, for the purpose of keeping the hollow block cool, and preventing
the cable being injured by heat. The core seat with the rings or dies for forming the
thickness of lead covering are inserted in this hollow block, and the cores for guiding
the cables or wires to be covered are screwed into position from the outside of the
container, and regulated by means of screws. The cores for guiding the cables through
the hollow block, horizontally, may be constructed hollow, or double cased, so as to
admit of a constant free circulation of cold water for keeping the cores cool and
preventing the cables being injured by heat.
In starting to cover cables the hollow or double cased core is screwed up against
the ring or die to prevent the lead passing through the side of the hollow block, on
the underside of the container: the cable is passed through this core, and when the
lead in the container is sufficiently cold, the core is unscrewed back a little to allow
the lead, or other compound, to pass round the same for the purpose of covering the
cable.

page_text: Instead of passing the cable through a body of molten lead, or other compound, it is
only exposed thereto at the point of contact.
The object of the fourth part of my invention is to cover with lead, or other com-
pound a series of cables forming insulated coverings, at one operation by mean of cores
and dies, similar in construction to that described in the third part of this Specifi-
cation; and for the purpose of covering any number of telegraph or telephone cables
by wires by lead pipe lining or coating, by hydraulic pressure, in lead pipe machines,
or hydrulic presses, and containers therefor.
And in order that my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is an elevation (partly in section) showing the general arrangement of my
hydraulic pipe press, and Figs. 2. 3 4. 5 6 and 7 show my improvements.
Referring to Fig. 17 is the water cylinder p is the ram, a is the container, resting
upon the bottom block c, the whole being sustained by the ramp and raised and.
lowered therewith and thereby. m is an inlet for water to the small ram w leading to
the bottom of the cylinder 1, for small pressures. The head of the ram w is enlarged
and fitted with a cup leather, below the part shown broken off in the drawing. n is
the lead or other metal or metallic compound under pressure.
Fig. 2 is a sectional elevation on the line 1-2 and Fig. 3 is a horizontal section, on
the line 3-4.
a is the lead container. b the fixed plunger which is used in a similar manner to
that used in hydraulic pipe pressos, (as shown in Fig. 1). c is my improved hollow
bottom block, having water passages as shown at d and e. The circulation of the
water is kept up by a continuous supply of cold water either from a pump, accumulator,
or other convenient supply. By this continuous supply of water the core seat f, which
is constructed in halves, is kept cold, thus preventing injury from heat to the cable
being covered. g, is the ring or die which governs the thickness of the covering to
the cable. The position of the cone for guiding the cable while being covered, is
made adjustable by means of the screws r and s; the screw r is used to withdraw the
conical end of h from the die g, and the screws is used to advance the same towards
the die g. ii are the passages for the metal as indicated by the arrows, from which
passages the metal is forced through the die g, and caused to surround the cable o, as
a solid drawn or seamless coating thereto.
Fig. 4 is a section on the line 5-6 of Fig. 3 showing the die 9, and the
passages i i.
I sometimes use a hollow or cellular cone constructed in one piece as shown in
Fig. 5, a circulating stream of cold water being used therein, as indicated by the
arrows, to prevent overheating.
Figs. 6 and 7 illustrate my method of producing from one to four or more pipes, at
one time. Fig. 6 is a sectional elevation on the line 7-8. and Fig. 7 is a section on
the line 9-10. The container a is similar to those used in lead pipe presses having
core seats kk cut out at the bottom whereby the crossbridge cores and dies for making
the pipes are inserted, as shown at kk. The crossbridge cores and dies are similar to
those used in lead pipe presses, and will be readily understood from the drawings.
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 :
1. The improved method of covering telegraph and telephone cables and wires with
lead or other metal or metallic compounds for electric purposes substantially as herein-
before described and illustrated by Figs. 2. 3. 4 and 5 of the drawings.
2. The improved method of manufacturing rods and seamless tubes or pipes,
substantially as hereinbefore described and illustrated by Figs. 6 and 7 of the
drawings.
3. The manufacture and use of the improved machinery for covering telegraph and
telephone cables with lead or other metal or metallic compounds, consisting of the

page_text: container a, in combination with the plunger b, the hollow or cellular bottom c having
water chambers and passages for the inlet and outlet of cold water, the core seat f
formed in two parts, for securing the die g in position the die g regulating the
external diameter of the covering of the cable; the core seat facting as a support
to the conical guide h, the latter being regulated by the screws and s,
stantially as hereinbefore described and illustrated by Figs. 2. 3 and 4 of the
drawings.
sub-
4. In combination with machinery as aforesaid, the application and use of the
cellular form of conical guide , substantially as hereinbefore described and illustrated

5. The manufacture and use of the improved machinery for the formation of one,
two, three, four, or more rods or pipes, simultaneously, consisting of the combina-
tion of the container a, the plunger b, the cone seats and crossbridge cores and
dies, substantially as hereinbefore described and illustrated by Figs. 6 and 7 of the
drawings.
6. The general constructions, combinations, and arrangements of the several and
respective parts, constituting my improvements in the method of, and in machinery
for the manufacture of, metallic pipes and rods, and for covering the same and
telegraph and telephone cables and wires with lead or metallic compounds, for electric
purposes, substantially as herein before described and illustrated by the drawings.
