Improvements in Screw-gill Machinery for Operating upon Fibrous
..Material.
We, JOHN CHARLES WALKER and JONATHAN EDWARD STEPHENSON, trading
as John Perry, of Valley Road Shipley in the County of York, Machine Maker,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in that class of screw-gill machinery for
operating upon fibrous material in which "jockey" or guide-tension rollers are
mounted at the back of the screw-gills over the shanks of the screws such as
gill-drawing and gill-roving machines and particularly applicable when a number of
sets of screw-gills are arranged side by side.
Hitherto this class of machinery has been so constructed that there is considerable
difficulty in fitting the screw mechanism for operating the screw-gills in position
and also in effecting any repairs or alterations in this mechanism owing to the
peculiar arrangement and connection with the machine of the screw-blocks in which
the screws are mounted, and also the saddles for guiding the screw-gills, as
besides necessitating a large proportion of the relative fitting of said screws and
saddles being performed at the machine itself instead of at the bench it prevented
any alterations or repairs at these parts being made without in a great measure
dismantling the machine.
The object of our invention is to enable the several parts of the traversing
mechanism for each side of the gills to be accurately fitted and arranged in their
relative positions apart from the machine and also allow said mechanism to be
readily placed in position on the machine or removed therefrom without interfering
with the feed rollers and the drawing off rollers.
For this purpose we form the screw-blocks, the screw shank bearings, and the
saddles or gill-guides for each pair of screws as an independent attachment or
fitting of such a form that the whole attachment with the screws mounted therein
may be together placed and secured in position or bodily removed therefrom. The
said attachment may be made with a transverse joint between the screw-blocks and
the screw bearings to facilitate fitting the screws therein and in the case of
machines with several sets of gills side by side such attachments are mounted back
to back preferably on horizontal seats projecting from the divisional piece or frame
between each set of gills and are secured at the screw-block end by vertical bolts
arranged approximately midway between each set of gills so as to economise space.
In any case the form of the attachment is such that it does not interfere with the
support for the adjustment of the feed roller or drawing off rollers..
The spring guides or fingers for guiding the gills as they are passed from one
screw to the other are also preferably mounted upon sáid attachment or fitting.

Improvements.in Screw-gill Machinery for Operating upon Fibrous
Material.
We, JOHN CHARLES WALKER and JONATHAN EDWARD. STEPHENSON, trading
as John Perry of Valley Road, Shipley, in the County of York, Machine Maker,
do hereby declare the nature of this invention and in what manner the same is to

page_text: be performed, to be particularly described and ascertained in and by the following
statement:-
"
This invention relates to improvements in that class of screw-gill machinery for
operating upon fibrous material in which "jockey or guide-tension rollers are
mounted at the back of the screw-gills, over the shanks of the screws such as
gill-drawing and gill-roving machines and particularly applicable when a number
of sets of screw-gills are arranged side by side.
Hitherto this class of machinery has been so constructed that there is considerable
difficulty in fitting the screw mechanism for operating the screw-gills in position
and also in effecting any repairs or alterations in this mechanism owing to the
peculiar arrangement and connection with the machine of the screw blocks in which
the screws are- mounted, and also the saddles for guiding the screw-gills, which,
besides necessitating a large proportion of the relative fitting of said screws and
saddles being performed at the machine itself instead of at the bench, prevented any
alteration or repairs at these parts being made without in a great measure
dismantling the machine.
The object of our invention is to enable the several parts of the traversing
mechanism for each side of the gills to be accurately fitted and arranged in their
relative positions apart from the machine and also allow said mechanism to be
readily placed in position on the machine or removed therefrom without interfering
with the "jockey or feed rollers and the drawing off rollers.
For this purpose we form the screw blocks, the screw shank bearings, and the
saddles or gill-guides for each pair of screws as an independent attachment or
fitting of such a form that the whole attachment with the screws mounted therein
may be together placed and secured in position or bodily removed therefrom. The
said attachment may be made with a transverse joint between the screw blocks and
the screw bearings to facilitate fitting the screws therein. and in the case of
machines with several sets of gills side by side such attachments are mounted back
to back preferably on horizontal seats projecting from the divisional piece or frame
between each set of gills and are secured at the screw-block end by vertical bolts.
arranged approximately midway between each set of gills so as to economise
space. In any case the form of the attachment is such that it does not interfere
with the support or the adjustment of the "jockey" or feed rollers or drawing off
rollers.
To fully describe our invention reference is made to the accompanying sheet
of drawings forming a part of this Specification in which similar letters of reference
indicate corresponding parts in each of the figures.
Figure 1, is a transverse section of such parts of that class of screw-gill machinery
in which several sets of gills are mounted side by side as are necessary to illustrate
our improvements.
Figure 2, is a plan view of Figure 1 representing one divisional piece or frame
with one of said attachments fitted on either side but having the traversing screws
omitted.
Figure 3, is a front view of the same.

Figure 4, is a vertical section on the broken line y, z, Figure 2 and
Figure 5, is a similar section on the line a, b.
Figure 6, is a separate side view of the said divisional piece or frame and
Figure 7, is a plan view of the same.
Figure 8, is a separate plan view of one of the said attachments without the
traversing screws.
Figure 9, is a side view of the same showing the spring fingers for guiding the
gills from one saddle to the other in position thereon.
The divisional frame A, secured on the bed B has bracket pieces a, b & c
projecting on each side and. has openings d, e & fformed in it. The attachments C
and C¹ each have the screw block D and saddles E at one end and the screw shank
bearing-blocks F at the other end connected to D by the connecting piece G and
...

page_text: they are mounted back to back upon the bracket pieces a, b & c. The attach-
ment C has a lug g at the back of the block D and the connecting piece G has a
division at and the two parts connected together by the lugs i, i formed thereon
and a slot is also formed by the side of these lugs. The attachment C¹ is also
provided with similar lugs and a slot but they are so arranged in relation to the
lugs and slot of C that when the two attachments are placed back to back the
lugs g, a lie clear of each other side by side and the lugs i, i on C¹ pass through the
slot k in C whilst the lugs i, i on C pass through a similar slot in C¹ and thus allow
the two attachments to lie close together and economise space. When in position
on the divisional piece A the lugs g, g lie in the opening e and the connecting
pieces G, G lie in the opening d and the attachments are secured in this position
by the bolts o, o passed vertically through the lugs g, y and the holes n, n, formed
in A and also by the set screws J passed through a into F.
The bottom delivery roller may be mounted in the bearing H formed in A
and the "jockey" rollers may be supported on brackets or projections on A and the
driving mechanism may be carried in brackets projecting from the bed B or
arranged in any other convenient manner.
End plates may be secured to the attachments C and C₁ to form bearings for the
end of the screws either instead of or supplementary to the blocks D.
The spring guides or fingers L, L (Figure 9) for guiding the gills as they pass
from one screw to the other are preferably mounted on the bracket R secured to the
underside of the attachment so as to lie when in position between b and c. The
bracket R has arms 7, " on either side to which L, L are pivoted.
the pressure of the guides is regulated by the spring t and wing nut u on the rod x
passed through such guides.
And
Having now particularly described and ascertained the nature of our inven-
tion, and in what manner the same is performed, we declare what we claim is :
1. In that class of screw-gill machinery in which "jockey" or guide tension
rollers are mounted at the back of the screw-gills, mounting the traversing screws
in an independent attachment or fitting which attachment forms the saddles or gill
guides and is so constructed and arranged that said attachment with the screws in
position may be removed from the machine without dismantling said "jockey"
rollers, substantially as herein shown and described.
2. In that class of screw-gill machinery in which "jockey" rollers are employed,
the improved construction or arrangement of the parts forming the saddles or gill
guides and the support and screw-shank bearings for the screws, substantially as
herein shown and described and illustrated in the accompanying drawing.
3. In that class of screw-gill machinery in which "jockey" rollers are employed,
mounting the spring guides L, L upon the attachments C and C' substantially as
herein shown and described.
