We JOHN HAMER and WILLIAM HAMER of the firm of J. & W. Hamer of the
Walk Mills, Ashton-under-Lyne in the County of Lancaster Cotton Spinners, JOHN
HAMPSON in the employment of the said firm and EDWIN CROSSLEY of the firm of
Buckley and Crossley of the Tame Valley Spindle Works, Dukinfield in the County
of Chester, Spindle and Flyer Makers, do hereby declare the nature of this Invention
to be as follows:-
Our said Invention relates to means for preventing the oil which lubricates the
bearings of the bobbin driving wheels or spindles of slubbing, roving and inter-
mediate frames from reaching the bobbin ends and so discolouring and damaging the
yarn wound on the bobbins.
According to our Invention the ordinary flange on the bobbin driving wheel is
covered by a loose removable cap having a downwardly projecting flange at its outer
periphery whereby the driving flange is surrounded or boxed in so as to prevent oil
from the bearings being thrown off by centrifugal action. The said cap has a central
hole which when a long collar is used to carry the bobbin fits the said collar. When
short collars are employed the said central hole fits the spindle. The driving snugs
on the bobbin wheel flange project through slots formed in the cap and project above
the level of the cap, so as to engage with the driving slots cut in the bobbin foot. The
ordinary board or rail surrounds the cap. Each bobbin end is thus entirely cut off
from the lubricated bearings and is thus protected from damaging contact with the
lubricant either from its own collar or spindle bearings or from the bearings of
adjacent collars or spindles. The top of the driving flange on the bobbin wheel may
be slightly dished to receive a supply of lubricant.

We, JOHN HAMER and WILLIAM HAMER of the firm of J. & W. Hamer, of the
Walk Mills, Ashton-under-Lyne, in the County of Lancaster, Cotton Spinners, JOHN
HAMPSON in the employment of the said firm and EDWIN CROSSLEY of the firm of
Buckley and Crossley of the Tame Valley Spindle Works, Dukinfield in the County
of Chester, Spindle and Flyer Makers 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 and accompanying drawings :-
==
Our said Invention relates to means for preventing the oil which lubricates the
bearings of the bobbin driving wheels or spindles of slubbing, roving and intermediate
frames from reaching the bobbin ends and so discolouring and damaging the yarn
wound on the bobbins.
And in order that our said invention may be properly understood we will now
proceed more particularly to describe the same with reference to the annexed sheet of
drawings. Fig. 1 of the said drawings is a sectional view of the bobbin driving
wheel a with its supporting sleeve b which is carried by a snug on the lifting rail as is
well understood. The said lifting rail is not shown in the drawings. According to
our Invention the ordinary flange c on the boss a¹ of the bobbin driving wheel a is
covered by a loose removable hollow cap d which projects downward towards the
bobbin wheel so that the driving flange c surmounting the boss a¹ is surrounded or
boxed in so as to prevent oil from the bearings being thrown off by centrifugal action.
The top of the driving flange c is dished as shown so as to contain lubricant and direct
it to the spindle. The said cap d has a central hole which in the case of a short collar
fits the spindle e as shown. When a long collar is used to carry the bobbin the central
hole in the cap fits the said collar. The driving snugs on the bobbin wheel flange c
project through slots g formed in the cap and stand above the level of the cap as shown
so as to engage with the driving slots cut in the bobbin foot which is indicated by h.
Each bobbin end is thus entirely cut off from the lubricated bearings and is thus
protected from damaging contact with lubricant either from its own collar or spindle
bearings or from the bearings of adjacent collars or spindles. The ordinary board or
rail supported from the lifting rail surrounds the cap d and as the cap prevents the
oil from being thrown upon the board the bobbins when doffed can be placed upon
the said board without the risk of the yarn being damaged or discoloured by contact
with an oily surface.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed we declare that what we claim is :-
In slubbing, roving and intermediate frames protecting the bobbin ends from
contact with lubricant from the bearings of the bobbin driving wheel and spindle or
collar by means of a hollow shield or cap d, carried by the flange on the bobbin
driving wheel and having slots or apertures in the top through which the snugs for
driving the bobbin project, substantially as hercinbefore described and shown.
