PROVISIONAL SPECIFICATION.
Improvements in or appertaining to Noble's Combs.
We, JOHN CHARLES WALKER and JONATHAN EDWARD STEPHENSON,
both trading as John Perry, of Shipley Fields Mill, 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 or appertaining to the sliver guides
and feed boxes of Noble's combs and its object is to provide smooth rustless metal
guides and lids at a comparatively small cost.
To apply our improvements to the sliver guides we employ cast iron or other
rough metal guides and encase or cover the guide eyes as well as the front face of
the guides with sheet brass or other sheet metal previously stamped and pressed to
form. The sheet metal is turned over the edges of the guide and around the eyes
to secure it in position.
In a similar way we cover the underside of the feed box lids with sheet brass or
other suitable rustless metal and we connect it thereto by side flanges or in any other
convenient manner.
To keep the fibres passing through the feed boxes in a radial position parallel to
the sides of the box or to prevent them being laterally displaced by the drag of
the feed knife as they pass beneath we may form longitudinal fins or ridges along
either the bottom of the feed box or along the lid or along both the bottom and
the lid. But these fins or ridges are discontinued or taper away at the delivery
end of the boxes so as to prevent them being damaged when the lid is brought into
contact with the bottom.

COMPLETE SPECIFICATION.
Improvements in or appertaining to Noble's Combs.
We, JOHN CHARLES WALKER and JONATHAN EDWARD STEPHENSON,
both trading as John Perry, of Shipley Fields Mill, Shipley, in the County of
York, Machine Maker, 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 :-
This invention relates to improvements in or appertaining to the sliver guides
and feed boxes of Noble's combs and its object is to provide smooth rustless metal
guides and lids at a comparatively small cost.
To apply our improvements to the sliver guides we employ cast iron or other
rough metal guides and encase or cover the guide eyes as well as the front face of
the guide with sheet brass or other sheet metal previously stamped and pressed to
form. The sheet metal is turned over the edges of the guide and around the eyes
to secure it in position.
In a similar way we cover the underside of the feed box lids with sheet brass or
other suitable rustless metal and we connect it thereto by side flanges or in any other
convenient manner.

page_text: Reference is to be had to the accompanying drawing forming a part of this
Specification in which similar letters of reference indicate corresponding parts in
each of the figures.
Figure 1, represents an elevation of a sliver guide encased with sheet metal in
accordance with our invention.
Figure 2, represents a section of the same on the broken line a, b in the former
figure.
Figure 3, represents a similar section of the sheet metal cover only.
Figure 4, represents a section of the guide on the line c, d Figure 1. And
Figure 5, represents a similar section of the sheet metal cover only.
Figure 6, represents a plan view of a feed box lid encased with sheet metal.
Figure 7, represents an underside view of the same.
Figure 8, represents à longitudinal section on the broken line e, f Figure 6.
Figure 9, represents a cross section on the line, 9, h Figure 6.
Figure 10, represents a section of the sheet metal cover only on the line i, j
Figure 7. And
Figure 11, is a longitudinal section of the same on the broken line y, z.
Referring firstly to Figures 1 to 5 the foundation A of the sliver guide is a
tough iron casting placed inside the casing B previously stamped and pressed to
the form illustrated by the sectional views Figures 3 and 5. The extreme edges C
of the casing are then turned over the back of the casting as shown in Figures 2
and 4 to secure the casing thereon.
In Figures 6 to 11 the foundation D of the feed box lid is made of iron and has
a rabbet E formed around the top of the sides F, F and the end H to receive the
turned over edges J of the casing K. The casing K is stamped and pressed to the
form shown in the sectional views Figures 10 and 11 and the edges J are turned
over after the foundation D has been placed in position.
To keep the fibres passing through the feed boxes in a radial position in relation
to the comb circle, and parallel to the sides of the box, and prevent them being
laterally displaced by the drag of the feed knife as they pass beneath said knife,
we form fins or ridges L in the underside of the casing K. These fins or ridges
preferably taper away or are discontinued at the delivery end N of the lid so
as to prevent them being damaged when the lid is brought into contact with the
bottom.
Similar fins or ridges may be formed along the bottom of the feed boxes
particularly when the bottom of the boxes is formed of sheet metal.
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. A sliver guide having a foundation of unfinished and inferior metal encased
with a rustless metal formed and secured substantially as herein shown and
described and illustrated in the accompanying drawings.
2. A feed box lid having a foundation of inferior metal encased by a casing of
rustless sheet metal formed and secured substantially as herein shown and described
and illustrated in the accompanying drawings.
3. A feed box having projecting fins or ridges L either on the underside of the
lid or on the bottom of the box, substantially as herein shown and described and
for the purpose specified.
