PROVISIONAL SPECIFICATION.
Improvements in Arrangements for Protecting from Breakage Guide
Rods Formed of Glass or similar Brittle Material Used in Machines
for Spinning, Doubling, and Winding, or otherwise Treating Yarns
or Threads.
We, SAMUEL HERBERT BROOKS, of Union Iron Works, West Gorton, and Junction
Iron Works, Miles Platting, Manchester, both in the County of Lancaster, Machine
Maker, and WILLIAM NAPIER of 39 Barrett Street, Old Trafford, Manchester aforesaid,
Mechanic, do hereby declare the nature of the said invention, to be as follows :-
Rods of glass or similar brittle material are used in the water troughs and on the
front edges of thread boards of doubling and twisting frames and on the copping
rails of winding frames and in other machines for treating yarns or threads
and are used for guiding the threads passing through the mechanism of the
machines.
These rods of glass or like material are frequently broken by the accidental fall of
a bobbin or other article or from other causes and our invention has for its object to
protect them from breakage.
Our invention consists in enclosing the glass or other like rods used for the above
named purpose in a tube of brass or other suitable metal which tube has nicks spaces
or grooves cut across it at the points where the thread is to come in contact with the
glass or other rod of similar material.
In some cases the rods of glass or other similar material have nicks or grooves in
them which in this case are brought opposite the said nicks spaces or grooves in the
metal tube.
In some cases segments of tubes of metal or other material are used to cover and
protect the rod of glass or like material which segmental cover has a groove, space or
nick in it to allow the thread to come in contact with the rod.

Improvements in Arrangements for Protecting from Breakage Guide
Rods Formed of Glass or similar Brittle Material Used in Machines
for Spinning, Doubling, and Winding, or otherwise Treating Yarns
or Threads.
We, SAMUEL HERBERT BROOKS, of Union Iron Works, West Gorton, and Junction
Iron Works, Miles Platting, Manchester, both in the County of Lancaster, Machine
Maker, and WILLIAM NAPIER, of 39 Barrett Street, Old Trafford, Manchester afore-
said, Mechanic, 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 :—
Rods of glass or similar brittle material are used in the water troughs, and on
the front edges of thread boards of doubling and twisting frames, and on the rails
of winding frames, and in other machines for treating yarns or threads, and are
used for guiding the threads passing through the mechanism of the machine.
These rods of glass or like material are frequently brokon by the accidental fall
of a bobbin or other article or from other causes and our invention has for its object
to protect them from breakage.
Our invention consists of enclosing the glass or other like rods used for the above

page_text: named purpose in a tube of brass or other suitable metal or material which tubo has
nicks, spaces or grooves cut across it at the points where the thread is to come in
contact with the glass or other rod of equivalent material.
In some cases the rods of glass or other equivalent material have nicks or grooves
in them which in this case are brought opposite the said nicks, spaces or grooves in
the tube of metal or other material.
In some cases segments of tubes of metal or other suitable material are used to
cover and protect the rod of glass or other equivalent material which segmental
cover has a groove, space or nick in it to allow the thread to come in contact with
the rod.
Fig. 1 is a front elevation, and fig. 2 is a cross section at A-B fig. 1, illustrating
our invention as applied to the thread board of a doubling and twisting frame,
commonly termed a doubling frame.
The mode of applying our invention for protecting rods of glass or other equiva-
lent material will vary in details according to the position occupied by the glass rods
or their equivalents in the machine to which our invention is applied.
a, is part of the roller beam of a doubling frame; b, are brackets secured to the
front part of the roller beam each by a bolt b', which brackets are say, about 20
inches apart.
Between each two brackets the thread board c, is hinged to turn upon pivots c¹,
having their bearings in the brackets b.
Ordinary unprotected glass rods have hitherto been applied to the top front edge
of the thread board by means of a clip at each end.
Our invention consists in applying a tube d, of metal or other suitable material
made of brass by preference, to the upper front edge of the thread board which
tube is secured at each end by clips d¹, of metal or other material to the thread
board c.
Within this tube d, the glass or other equivalent rod e, is inserted and slots nicks
or spaces d², are cut in the upper edge of the tube opposite each spindle or the threads
to be guided, so that the threads being doubled and twisted can enter the said slots or
spaces for them and come in contact with the surface of the guide rod of glass or
equivalent material.
e,
should
With this arrangement it is not necessary that the glass or equivalent rod
be all in one length, for each separate length of thread board, but may be made up
of short lengths so long as a portion of the glass or equivalent rod is opposite to
each slot or space formed in the tubo d, and if required, the glass or other equivalent
rod or rods may be moved end ways at times to present a fresh surface to the passing
threads.
In some cases the tube d, may be dispensed with, and a cover plate of metal or
other material substituted, the plate being turned to come sufficiently round the glass
rod or its equivalent to protect it, this cover plate having the required slots or spaces
cut in it to allow the threads to come against the surface of the glass rod or other
equivalent material.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is.
In doubling frames and other machines in which rods of glass or other equivalent
material are used for guiding passing threads, the combination of the rod of glass or
other equivalent material with a tube or covering plate of metal or other material,
having slots, nicks or spaces in it for the threads to pass through, substantially as and
for the purpose herein before described and illustrated by the drawings.
