PROVISIONAL SPECIFICATION.
Improvements in Machinery or Apparatus for Gilling or Combing
Wool or other Fibres.
We, PETER OLDFIELD, Combing Manager of 13, Burlington Terrace, Thorn-
bury Bradford in the County of York, and THOMAS SPENCER, Draper, of
63, Sunbridge Road, Bradford aforesaid, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in machinery or apparatus for gilling or
combing fibres. The gills or fallers of this class of machinery are frequently
heated by gas or by means of a steam chest placed beneath the bottom row of gills
but in the former case there is great liability to overheat the gills whilst in the
latter the heat is rarely sufficient.
Our improvements consist in introducing an intermediate chest or oven heated by
steam or other means between the two sets of gills that is immediately below the
gills whilst they are in actual operation upon the fibres and in the case of curved
gills or fallers the said intermediate steam chest is made to conform as closely as
possible to the shape of the gills. We also preferably retain the ordinary steam
chest below as well.
By this arrangement the fallers rise up into action in a heated state from the
bottom row in the ordinary manner but as they are traversed in close proximity
with the said intermediate steam chest the heat they impart to the fibres is
constantly renewed and a higher temperature is generally maintained.
Dated this 22nd day of October 1891.

Improvements in Machinery or Apparatus for Gilling or Combing
Wool or other Fibres.
We, PETER OLDFIELD, Combing Manager, of 13, Burlington Terrace, Bradford,
in the County of York, and THOMAS SPENCER, Draper, of 63, Sunbridge Road,
Bradford, aforesaid, 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 machinery or apparatus for gilling
or combing fibres. The gills or fallers of this class of machinery are frequently
heated by gas or by means of a steam chest placed beneath the bottom row of gills
but in the former case there is great liability to over heat the gills whilst in the
latter the heat is rarely sufficient.
Our improvements consist in introducing an intermediate chest or oven heated by
steam or the like between the two sets of gills that is immediately below the gills
whilst they are in actual operation upon the fibres and in the case of curved gills
or fallers the said intermediate steam chest is made to conform as closely as possibly
to the shape of the gills. We also preferably retain the ordinary steam chest below
as well.
By this arrangement the fallers rise up into action in a heated state from the
bottom row in the ordinary manner but as they are traversed in close proximity
with the said intermediate steam chest the heat they impart to the fibres is
constantly renewed and a higher temperature is generally maintained.

Specification in which similar letters of reference indicate similar parts in both the
figures.

Figure 1, represents a transverse section parallel to the fallers of such parts of
a screw gill box as are necessary to illustrate the application of our improvements
thereto.
Figure 2, is a separate plan view of the steam chest.
The steam chest A is supported by the lips B projecting from the front of the
saddles C on which the gills or fallers D slide. And the chest A is preferably of
such a depth or thickness and is placed in such a position that the underside of the
fallers pass along in actual contact with it whilst the underside of A is quite clear
of the pins E of the lower fallers D'. Steam is supplied to the chest by the
admission pipe G passing through the saddle C and the exhaust pipe H conveys
the steam from the chest to the waste pipe. Or on leaving the pipe H the steam
may be first passed through the lower steam chest J placed entirely below the
.fallers.
In order to allow the chest A to be made of thinner metal and also to allow the
chest itself to be made thinner as well as to enable it to stand a greater steam
pressure a number of stays S are riveted to the top and bottom plates of the chest
so as to keep them in their proper relative position.

""
In the case of curved gills or fallers like those used in
nip combs a similar
arrangement is employed but the steam chest is made the same curve as the fallers
so that the latter may travel closely in contact with it.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare what we
claim is :
In screw gill machinery for gilling or combing fibres, the means or method of
heating the gills or fallers by means of an intermediate steam chest or oven
mounted between the two sets of gills, substantially as herein shown and described
and illustrated in the accompanying drawings.
