PROVISIONAL SPECIFICATION.
Improvements in Wet and Dry Spinning Frames.
JAMES MACKIE of Albert Foundry Springfield Road in the City of Belfast
Machine Manufacturer and SINCLAIR HUNTER, Foundry Manager of 160 Albert
Bridge Road, Mountpottinger Belfast in the County of Down, both in Ireland do
hereby declare the nature of this invention to be as follows:-
:―
These improvements relate to dry spinning frames, for jute & similar fibres, and
are intended to provide a means of protecting the collar bearings of the spindles
of these frames from the sand or dust which falls out of the yarn in the process
of spinning these fibres.
The ordinary spindle necks of these dry spinning frames are made conical with
adjustable bushes or collars for taking up wear, which owing to the presence of
aforesaid dust is extreme, but this conical form owing to the necessarily large
diameter at the bottom involves great friction & waste of driving power.
The parallel collars of small diameter as used in wet spinning machinery run
much lighter & require less power than the conical form, but are unsuitable for
dry spinning frames, owing to the extreme wear & absence of means of adjustment.
Now our improvement consists in the use of a guard or washer fixed on the
spindle above the collar bush and revolving with it. This guard is of such form
and dimensions as to fully cover & protect the collar bearing from dust. It can be
fixed on spindle by a screw or other convenient means.
The above guard can also be used on the spindles of wet spinning frames for the
purpose of protecting the collar bearing from water, acids etc.

Improvements in Wet and Dry Spinning Frames.
JAMES MACKIE of Albert Foundry Springfield Road, in the City of Belfast,
County Antrim, Ireland, Machine Manufacturer, and SINCLAIR HUNTER, Foundry
Manager, formerly of 160 Albert Bridge Road, Mountpottinger, Belfast in the
County of Down Ireland, now of 2 Springfield Villas, Springfield Road Belfast,
County Antrim, Ireland 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 :-
These improvements relate to dry spinning frames, for jute and similar fibres,
and are intended to provide a means of protecting the collar bearings of the
spindles of these frames from the sand or dirt which falls out of the yarn in the
process of spinning these fibres.
The ordinary spindle necks of dry spinning frames are made conical with
adjustable bushes or collars for taking up wear, which owing to the presence of
aforesaid dust is extreme, and this conical form, owing to the necessarily large
diameter at the bottom involves great friction and waste of driving power.
The parallel collars of small diameter as used in wet spinning machinery run
much lighter and require less power than the conical form but are unsuitable for

page_text: dry spinning frames, owing to the extreme wear, when not protected from the dust,
and absence of means of adjustment.
Our improvement consists in the use of a guard or washer fixed on the spindle,
above the collar, and revolving with it. This guard is of such a form and
dimensions as to fully cover and protect the collar bearing from dust. It can be
fixed on spindles by screwing to same or by other convenient means.
The drawing accompanying this Specification clearly shows the arrangement,
A is the guard or washer and is shown screwed on to the spindle B, above the
parallel collar C.
The above guard can also be applied to the spindles of wet spinning frames for
the purpose of protecting the collar bearing from water or acids."
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The use of a guard or washer fixed on any spinning spindle, above the collar,
to protect the bearing, substantially as described.
2. The use of a guard or washer, in conjunction with a parallel neck, and fixed
on dry spinning spindles, above the collar, to protect the bearing substantially as
described.
