Year: 1880

page_text: LETTERS PATENT to Walter Twiss Glover and George Frederick James, both of
Salford, in the County of Lancaster, for an Invention of "IMPROVEMENTS IN
MACHINERY FOR BRAIDING, LAPPING, OR OTHERWISE COVERING TELEGRAPH
WIRES, CRINOLINE-STEEL, ENGINE PACKING, OR OTHER CORES, WITH
TEXTILE OR OTHER MATERIAL FOR INSULATING, PROTECTIVE, AND OTHER
PURPOSES."
PROVISIONAL SPECIFICATION left by the said Walter Twiss Glover and
George Frederick James at the Office of the Commissioners of Patents on the
14th December 1880.
WALTER TWISS GLOVER and GEORGE FREDERICK JAMES, both of Salford, in
the County of Lancaster. "IMPROVEMENTS IN MACHINERY FOR BRAIDING,
LAPPING, OR OTHERWISE COVERING TELEGRAPH WIRES, CRINOLINE-STEEL, ENGINE
PACKING, OR OTHER CORES, WITH TEXTILE OR OTHER MATERIAL FOR INSULATING,
PROTECTIVE, AND OTHER PURPOSES."
This Invention relates to improvements in machinery for braiding, lapping, or
coating telegraph wires, crinoline-steel, engine packing, or other cores, with textile
or other material.
Hitherto it has been the practise to pull or draw the material after it has been
braided, lapped, or otherwise covered through the braiding or other machine by
means of roughened rollers which have necessarily exercised pressure upon the
covered material, and which has frequently resulted in the coating being injured or
cut, involving loss of time and material.
Now this Invention consists of an arrangement of mechanism for forcing the iron,
copper, or other metallic wire, crinoline steel, engine packing, or other cores required
to be coated or covered with textile or other covering material, through the braiding
or other machine employed, and for this purpose we apply a pair of squeezing rollers
which exercise pressure upon the naked wire or other core, and so we force the
same through the central tube of the machine, the braiding, lapping, covering, or
other operation taking place between such rollers and the mouth or entrance of the
said central tube. In this manner we are enabled to exercise the required pressure
upon the wire or other core, and in case of cores being already covered, and
therefore liable to injury by pressure, we employ metalic rollers covered with india
rubber or other suitable yielding substance.

WALTER TWISS CLOVER and GEORGE FREDERICK JAMES, both of Salford, in
the County of Lancaster. "IMPROVEMENTS IN MACHINERY FOR BRAIDING,
LAPPING, OR OTHERWISE COVERING TELEGRAPH WIRES, CRINOLINE-STEEL, ENGINE
PACKING, OR OTHER CORES, WITH TEXTILE OR OTHER MATERIAL FOR INSULATING,

This Invention relates to improvements in machinery for braiding, lapping, or
coating telegraph wires, crinoline steel, engine packing, or other cores, with textile
or other material.
Hitherto it has been the practice to pull or draw the material, after it has been
braided, lapped, or otherwise covered, through the braiding or other machine by
means of roughened rollers, which have necessarily exercised pressure upon the
covered material, and which has frequently resulted in the coating being injured or
cut, involving loss of time and material. Now this Invention consists of an arrange-
ment of mechanism for forcing the iron, copper, or other metallic wire, crinoline
steel, engine packing, or other cores requiring to be coated or covered with textile or
other covering material, through which the braiding or other machine employed, and
for this purpose we apply a pair of squeezing rollers, which exercise pressure upon the
naked wire or other core, and so we force the same through the central tube of the
machine, the braiding, lapping, covering, or other operation taking place between
such rollers and the mouth or entrance of the said central tube. In this manner we
are enabled to exercise the required pressure upon the wire or other core, and in
case of cores being already covered, and therefore liable to injury by pressure, we
employ metallic rollers covered with india rubber or other suitable yeilding
substance.
On the accompanying Drawing we illustrate an arrangement of mechanism
constructed in accordance with our Invention, and will now proceed to describe
the same by reference to the Figures and letters marked thereon. Fig. 1 represents
a side sectional view of so much of the top of the braiding spindles and hollow
central tube of a braiding machine as is requisite to illustrate the application of our
improved squeezing rollers which are shewn applied thereto; and Fig. 2 is a plan
of Fig. 1. A is the central hollow tube through which the wire or other core or
cores requiring to be covered is or are to be forced; and B, B, are the tops of the
braiding spindles, the bobbins of which are marked C, C. These spindles revolve
round the central hollow tube A in the ordinary manner, and no novelty is claimed
in them. At a convenient distance above the mouth of the hollow central tube A
we mount a pair of squeezing rollers D, D, which are geared together in the
frames E by the spur wheels G, and revolving motion is communicated to these
rollers at the desired speed and in the direction of the arrows by the worm wheel H
affixed upon one of their axes. These rollers D, D, are adjustable in their distance
from each other by means of the set screws I and spring J, the set screws J being
provided with lock nuts K to ensure their remaining stationary. The action of this
mechanism is as follows:-The end edge of the wire or other material L requiring to
be covered or coated is first passed between the feeding rollers D and then introduced
into the mouth of the central tube A. The machinery being now set in motion
the feeding rollers D force the wire L down the tube A, whilst the braiding spindles
simultaneously cover or braid the same with textile or other material drawn off the
bobbins, and if desirable to introduce yarn of textile material or lengths of india
rubber or other material to form an additional coating between such wire or central

page_text: core and the outer braiding material, it is only requisite to employ a central guide
piece O (as shewn in plan, Fig. 3) with holes M surrounding the central opening N,
through which holes M the additional coating material is guided in being drawn
off the creel or bobbins, the position of this guide piece O when used being indicated
by the dotted lines in Fig. 1. Although only illustrated and described in reference
to braiding machinery it will be obvious that the same arrangement of mechanism
is useful for lapping and other machinery for covering, coating, and other analogous
purposes.
We claim as our Invention,-
The use and application of feeding rollers to braiding, lapping, and other similar
machinery, substantially as and for the purposes hereinbefore described and
illustrated on the accompanying Drawing.
In witness whereof, we, the said Walter Twiss Glover and George Frederick
James, have hereunto set our hands and seals, this Thirteenth day
of June, in the year of our Lord One thousand eight hundred and eighty
one.
