PROVISIONAL SPECIFICATION.
Improvements in or appertaining to the Drawing Off Rollers of Gill
Boxes, Drawing Boxes, Combs and the like.
We, ALBERT FARRAR, of 51, Holme Street, Little Horton, Bradford, in the
County of York, Combing Overlooker, and JOSEPH EDWARD FARRAR, of 13, Mount
Street, Cleckheaton, in the aforesaid county, Carding Overlooker, do hereby
declare the nature of this invention to be as follows:
The drawing off rollers of gill boxes, drawing boxes, combs, and like, machines
for combing fibres have one roller (commonly termed the press roller) laterally
moveable in relation to the other roller, and our improvements relate particularly
to drawing off rollers in which the pressure is applied by a spring or springs.
The primary object of the invention is to prevent the damage to the "leathers"
occasioned when the springs are accidentally or unwittingly compressed to such au
extent that there is not sufficient latitude left to allow abnormally thick parts of
the leather or an exceptional quantity of fibres to pass without undue pressure.
Our improvements consist in introducing an india rubber block or cushion
between the springs and the bearings or other suitable point in such a manner
that although the spring may be completely compressed there remains sufficient
elasticity or "give" in the india rubber block or cushion to prevent serious
damage.
The improvements are also applicable to rollers in which the pressure is applied
by means of a weight and lever.

Improvements in or appertaining to the Drawing Off Rollers of Gill
Boxes, Drawing Boxes, Combs, and the like.
We ALBERT FARRAR, of 51, Holme Street, Little Horton, Bradford, in the
County of York, Combing Overlooker, and JOSEPH EDWARD FARRAR, of 13, Mount
Street, Cleckheaton, in the aforesaid county, Carding Overlooker, 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 :-
The drawing off rollers of gill boxes, drawing boxes, combs, and like machines
for combing fibres have one roller (commonly termed the "press" roller) laterally
moveable in relation to the other roller, and our improvements relate particularly
to drawing off rollers in which the pressure is applied by a spring or springs.
The primary object of the invention is to prevent the damage to the "leathers"
occasioned when the springs are accidently or unwittingly compressed to such au

page_text: extent that there is not sufficient latitude left to allow abnormally thick parts of
the leather or an exceptional quantity of fibres to pass without undue pressure.
Our improvements consist in introducing an india-rubber block or cushion
between the springs and the bearings or other suitable point in such a manner
that although the spring may be completely compressed there remains sufficient
elasticity or give
in the india rubber block or cushion to prevent serious
damage.
"
The improvements are also applicable to rollers in which the pressure-is applied
by means of a weight or lever.
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, represents an elevation of a bearing standard for supporting the
bearings of the feed rollers of a screw gill box to which our improvements are
applied.
Figure 2, is a plan view of a pair of drawing off rollers of a "Noble's" comb
with our improvements applied.
Figure 3, illustrates the application of our improvements to a pair of rollers
fitted with Messrs. Wharton & Monies' improvements shown in their specification
No. 14854 of 1892.
Figures 4 to 7 are views of detail hereinafter referred to.
In Figure 1, the cylindrical box A is placed on the bearing B of the
press roller
spindle C, round the rod D. Figure 4, represents a cross section of the bearing
with a portion of the rod together with a diametrical section of the box A. An
india rubber block E is placed within the box and a metal cap F is placed upon
it and forms a seat for the bottom of the spring G.
To apply our improvements to drawing off rollers we cast a box or recess A;
Figure 2, on the back B2 of the bearing B of the press foller and we place an
india rubber block E in this recess and cover it with a cap or plate F against the
centre of which the screw H bears. Figure 5, represents a sectional plan of the
bearing B and parts connected with it.
In Figure 3 the box A is introduced between the end of the spring G and the
screw H. The box is filled with an india rubber block E and the plate against
which the screw H bears is placed over it. Figure 6, represents a vertical section
of the box and Figure 7, a cross section on the broken line a, b Figure 3.
We find that india rubber introduced in this manner between the spring
pressure and the bearings of the press rollers enables inequalities in the leathers
or the like or inequalities in the material passing through the rollers to more
readily pass as the india rubber is more resilient also reduces the vibration
consequently the pressure between the rollers does not require to be so great.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is :
The combination with the bearings of "press" rollers of the enclosed india
rubber blocks arranged substantially as herein shown and described and illustrated
in the accompanying drawings.
Dated this 2nd day of June 1897.
