PROVISIONAL SPECIFICATION.
Improvements in Bearings or Holders for Spinning, Twisting, or
Winding Spindles.
We. JOHN BOYD and THOMAS ALEXANDER BOYD, of Shettleston Iron Works, in
the County of Lanark, North Britain, Engineers, do hereby declare the nature of this
invention to be as follows, that is to say :-
Our said invention has for its object to improve the form and mode of holding long
tubular reservoir bearings or holders, used principally for long and heavy ring
spindles or for long and heavy flyer spindles, and to render the driving of such
spindles easy and uniform and their motion free from injurious vibration. With the
improved construction the spindle assumes the axis of rotation about which it can
rotate most freely. Our improvements are also applicable for winding spindles.
Our improved mechanism comprises a long tubular holder of a kind described and
delineated in our Patent Specification No. 2757 of 1881 and having internal upper and
footstep bearings and an oil spout extending out from the upper part of the holder
and upward clear of the driving pulley on the spindle, such spout not only giving
additional oil space but also enabling the attendant to see if there is a sufficient head of
oil in the holder, and to supply oil when required without lifting the spindle out of
its socket in the holder. The holder instead of being held rigidly in position as
formerly by pinching screws in the upper and lower rails, is held loosely and
pendulously so as to project down through a hole in a single rail, being carried by a
bracket fixed on the rail and which encircles the neck of the holder except at one
part where it is cut away or slotted for the oil spout. The holder is suspended' by a
collar on its upper end which rests on the top of the bracket, and it is kept from
turning by the oil spout projecting through the cut away part of the bracket or by a
pin without the spout. The driving pulley is as before formed on a boss in a manner
to encircle the bracket and top of the holder; and when the spindle runs at a high
speed it adjusts itself to a steady axis of rotation, whilst the holder tends, in its normal
state, to hang plumb without the aid of springs or cushions, and the pull of the
driving band keeps the neck of the holder against the back internal surface of the
bracket. The bracket may be made with two backwardly projecting lugs and a
fulcrum pin between them as and for the purposes described in our Patent Specification
No. 18920 of 1888.

COMPLETE SPECIFICATION.
Improvements in Bearings or Holders for Spinning, Twisting or
Winding Spindles.
We, JOHN BOYD, and THOMAS ALEXANDER BOYD, of Shettleston Iron Works, in
the County of Lanark, North Britain, Engineers, 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, that is to say :-
Our said invention has for its object to improve the form, and mode of holding, of
long tubular reservoir bearings or holders used principally for long and heavy ring
spindles or for long and heavy flyer spindles; and to render the driving of such spindles
easy and uniform, and their motion free from injurious vibration.
With the improved
construction the spindle assumes the axis of rotation about which it can rotate most
freely. Our improvements are also applicable for winding spindles.

page_text: Mechanism constructed according to our present invention is shown on an
accompanying sheet of explanatory drawings,
Figure, 1, being a vertical section, and
Figure, 2, a sectional plan.
Our improved mechanism comprises a long tubular holder, A, of a kind described
and delineated in our Patent Specification No. 2757. of 1881, and having internal
upper and footstep bearings, A 1, A 2, and an oil spout, B, projecting out from the
upper part of the holder, A, and extending upwards, clear of the driving pulley, C1,
..on the spindle, C. This spout not only gives additional oil space but also enables the
attendant to see if there is a sufficient head of oil in the holder, A, and to supply_oil
when required without lifting the spindle out of its socket in the holder. The
holder, A, instead of being held rigidly in position as formerly by pinching screws, in
upper and lower rails of the framing, is held loosely and pendulously so as to project
down through a hole in a single rail, 1), being carried by a bracket or supporting
piece, D 1, fixed on the rail, D, and which encircles the neck of the holder, A, except at
one part where it is cut away or slotted for the oil spout, B. The holder, A, is
suspended by a collar, A 3, formed on its upper end, which collar rests on the top of
the bracket, 1) 1, and it is kept from turning by the oil spout, B, projecting through
the cut-away part of the bracket, D 1. The driving pulley, C1, is as before, formed
on a boss, 2, fixed on the spindle, C, and formed so as to encircle the bracket, D 1,
and the top of the holder, A; and when the spindle runs at a high speed it adjusts
itself to a steady axis of rotation, whilst the holder tends in its normal state to hang
plumb without the aid of springs or cushions, and the pull of the driving band keeps
the neck of the holder against the back internal surface of the bracket, D 1. The
bracket, D 1, may be made with two backwardly projecting lngs as indicated by dotted
lines, D2, D3, and a fulcrum pin, D4, between them as and for the purposes described
in our Patent Specification No. 18920 of 1888.
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:-
The improved construction of bearings or holders for spinning, twisting, and wind-
ing spindles, and comprising in combination the long tubular reservoir holder, with its
oil spout, and supported pendulously by means of a collar at its upper end, and the
bracket or supporting piece carrying the holder and fixed on the rail, substantially
as hereinbefore described.
