PROVISIONAL SPECIFICATION.
Improvements in Roller Stands and Slides of Machinery for
Preparing and Spinning Fibres.
EDMUND TWEEDALE, SAMUEL TWEEDALE and JOSEPH SMALLEY, Machinists,
Castleton, near Manchester, do hereby declare the nature of this invention to
be as follows:-
In machinery for preparing & spinning cotton & other fibrous material, it is
customary to bush the roller stands & slides with brass to prevent the wearing of
the roller necks. These brasses have been made wider at the bottom than the top
to prevent them rising, & to assist in securing them in position. The widening of
these bushing brasses at the bottom tends to weaken the stands & slides, & the
object of this invention is to insert a wide brass for the roller neck to rest on
without weakening the stands or slides & at the same time facilitate the renewal of
the brasses when worn out & reduce the liability to break the stands & slides.
In carrying out this invention we form the bottom of the stand or slide with a
narrow taper groove, or hole, made wider at the bottom than at the top. The
bottom of the brasses to be inserted, are made to fit these grooves or holes, the
upper part being widened out to the required width for the roller neck, giving
a section where the brasses are secured to the stands or slides of a double V form.

COMPLETE SPECIFICATION.
Improvements in Roller Stands and Slides of Machinery for
Preparing and Spinning Fibres.
We, EDMUND TWEEDALE, SAMUEL TWEEDALE, and JOSEPH SMALLEY,
Machinists, Castleton, near Manchester, 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 :-
In machinery for preparing and spinning cotton and other fibrous material, it
is customary to bush the roller stands and slides with brass to prevent the
wearing of the roller necks. These brasses have been made wider at the bottom
than the top to prevent them rising, and to assist in securing them in position.
The widening of these bushing brasses at the bottom tends to weaken the stands
and slides, and the object of this invention is to insert a wide brass for the roller
neck to rest on without weakening the stands or slides and at the same time
facilitate the renewal of the brasses when worn out and reduce the liability to
break the stands and slides.
In carrying out this invention, we form the bottom of the stand or slide with
a narrow taper groove or hole, made wider at the bottom than at the top. The
bottom of the brasses to be inserted, are made to fit these grooves or holes, the
upper part being widened out to the required width for the roller neck giving a
section where the brasses are secured to the stands or slides of a double V form.
Such being the nature and object of our invention, we will make reference to the
accompanying sheet of drawings, wherein
Fig. 1 is elevation of a roller stand and slide employed in machinery for preparing
and spinning fibres.

page_text: A represents the roller stand and B the slide connected thereto by the set
screw C in the ordinary manner.
Our improvement consists in the manner or method of securing the brass bushes D
into the said roller stands and slides. The parts to which these brass bushes are
connected are cut out by being "milled" or by any other suitable means and the
brass bushes D which are made of the section shewn in the drawings are inserted into
their position endwise. By making the bushes of the shape shewn in the drawings,
they form a solid and durable bearing for the necks of the rollers, whilst the dove-
tailed grooves prevent the bushes rising from their seating, and when the bushes
are worn they can be easily driven out and new ones substituted without the
liability of breakages, which now frequently happens.
Instead of securing the brass bushes in dovetailed grooves as shewn in Fig. 1,
the underside of the brass bushes is made with one or more pegs or projections E
fitting into corresponding holes made in the roller stand and slide, the end of the
peg E being afterwards riveted against the shoulder which riveting can be
effected in any convenient manner by the insertion of a suitable tool passing up
through the openings F.
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 :-
Firstly. In roller stands and slides of machinery for preparing and spinning fibres,
the formation of double V or dovetailed openings or recesses substantially as shewn
in Fig. 1 for the reception of correspondingly shaped bearing bushes.
Secondly. In roller stands and slides of machinery for preparing and spinning
fibres, the means or method substantially as shewn in Fig. 2 for securing bushes to
their seatings.
