Improvements in Drawing Off Rollers on Combing Machines and
the like.
We, JESSE COOKE and ALFRED STEPHENSON, both of Market Street Works,
Keighley, in the County of York, Machinists, do hereby declare the nature of this
invention to be as follows:-
This invention relates to certain improvements in drawing off rollers on combing
machines and the like and relates more particularly to that class of machine known
as "Nobles combs" and has for its object the arrangement of same in such a manner
that pressure may be applied at one point instead of two as hitherto, and at the
same time to enable the operator to apply more pressure at one end of said rollers
than the other, thereby adjust the same to suit the varying thicknesses of the
leathers.
We accomplish our object in the following manner.
the drawing off rollers are formed somewhat as hitherto.
The brackets for supporting
To the back of one of said brackets we mount one end of a lever, the opposite
end of which is connected to a bar passing to the front of the rollers and is provided
with a thumb screw.
To the before mentioned lever is adjustably mounted a toothed or fluted quadrant
engaging with a rack secured to a bar communicating with the journals carrying
the drawing off rollers.
Upon operating the before mentioned thumb screw, pressure may be applied to
or removed from the said rollers.
By these means the pressure may be regulated at either end of the rollers to suit
the varying thickness of the leathers; and the leathers may be changed with great
facility.

COMPLETE SPECIFICATION.
Improvements in Drawing Off Rollers on Combing Machines and
the like.
We, JESSE COOKE and ALFRED STEPHENSON, both of Market Street Works,
Keighley, in the County of York, Machinists, 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 certain improvements in drawing off rollers on combing
machines and the like, and relates more particularly to that class of machine known
as "Nobles combs" and has for its object, the arrangement of same in such a manner
that, pressure may be applied at one point instead of two as hitherto, and at the
same time to enable the operator to apply more pressure at one end of said rollers
than the other, thereby adjust the same to suit the varying thicknesses of the
leathers.

page_text: In describing our invention in detail, reference is made to the accompanying
sheet of drawings in which
Fig. 1 represents an elevation of a pair of drawing off rollers constructed according
to our invention.
Fig. 2 is a similar view showing the lever disengaged and the top journal bracket
or block removed, and
Fig. 3 a plan of the top bracket or block.
The brackets A. and B. are each constructed with a recess for the reception of
the roller journals secured together and attached to some portion of the combing or
other machine in any convenient-manner.
To the end of the bottom bracket A. we mount one end of a lever C. to the
opposite end of which is hinged a bar D. threaded for some portion of its length and
provided with one or more thumb screw.nuts E.
To the said lever is adjustably mounted a fluted distance piece F, the fluted edge
engaging with a rack G. secured to or forming a part of the bar H. the respective
ends. of which engage with the journal blocks J. These blocks are mounted in slot
holes K. in the respective brackets A. and B. and on applying the lever C.. and
bar D. in the manner as shown by Fig. 1 and screwing the nuts E. so that the spiral
spring S. compresses the sliding piece L. against the support A' on top bracket,
pressure is applied to. the rollers R. and R' through the lever.C, distance piece F.
and cross. bar H.
If the distance piece F. is mounted to the lever C. so that pressure is applied on
the, centre. of cross. bar H.. as shown, then the, pressure. on the ends of, the rollers.is
equal, but should more pressure be required at one end of the rollers than.the
other, the distance piece F. is moved and the pin P. through same and one of the
boles Q. by which, when the nuts E. are tightened, more pressure is applied to
the journal nearest the distance piece F; thus by these means, the pressure may be
regulated, at either end of the rollers to suit the varying thicknesses of the leathers,
that is to say, when the leather is thicker on one edge than the other, by adjusting
the position of the distance piece F. the leather is squeezed more on one edge than
the other, thus, bringing it to a more equal thickness over the entire width of the
same.
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,
1. Drawing off rollers R. and R¹ with which are combined a cross bar H. and
rack G. a distance piece F. lever C. and screwed bar D, all arranged and operated
substantially in the manner shown and described and for the purpose as herein before
set forth.
2. A lever C. baving a series of holes Q. therein combined with a fluted distance
piece F. and a cross bar prepared with a series of flutes or teeth, the said bar
engaging with journal blocks J. substantially in the manner and for the purpose as
hereinbefore set forth.
