Improvements in Shafts and Caps for Wooden Rollers for Machines:
and in the Means of Attaching the same.
TEDDY ISHERWOOD Sewing and Wringing Machine Agent of No. 5 King
Street, Ramsbottom, in the County of Lancaster, 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 :-
My present invention relates to an improved construction and method of attaching
together the rollers, shafts, and caps for weaving, warping, washing, mangling,
carding, and other machines, and is an improvement upon the invention for which
Letters Patent No. 8163 of the year 1887 were granted to me.
in the accompanying drawings Figure 1 shews a new central shaft or screw
which I now use in place of the short shaft described in the Specification of the
above named Patent as being secured by means of a mut let into a recess cut in the
wooden roller. The said shaft or screws has formed upon it a specially constructed
V thread a. having a sharp edge. The body of the shaft may be taper or parallel
but I prefer to make it with a very slight taper as shewn. The outer end of the
shaft may be formed as before with a square part b, and a round part c and may be
screwed us at d or not as required.
Fig. 2. shews in interior elevation and Fig. 3. in cross section one method by which
I secure the roller, cap, and shaft together. s is the shaft, e the cap, and f the
roller, the cap having a flange y attached to it as is required for warper's, and
weaver's beams and the like. Longitudinal keys e¹ are formed inside the cap e as
in my former invention, but I now make them of wedge or tapered section as shewn
in Fig. 2. I also form similar keys across the inner end of the cap as shewn at e
dotted in Fig. 3. The cape has an exterior boss e³ formed upon it and the hole
for the shaft is made round for a portion of its length * and square for the other
portion the object being that it may suit shafts provided with the square bor
without it. is the usual ruffle or pulley and I form an enlargement e' sufficiently
wide to allow the insertion of screws h. A nut is shewn screwed on to the shaft s
thus further securing the cap; but this forms no part of my present invention.

In putting together the roller shaft and cap a hole having been truly bored in
the roller the size of the small part of the screw shaft s the said shaft is screwed
firmly into position, the thread a cutting its own groove as it proceeds. The roller
end having been turned correctly the cap e is forced on under considerable pressure,
hydraulic or otherwise, the keys e cutting their way into the wood, care being taken
that the cap is in the correct position to suit the square on shafts. The screws h,
and if desired the end screws k, are then inserted.
In Fig. 4. is shewn the form of cap used in connection with "batch" rollers for
bleachers; the cap e. having no ruffle nor flange but the screw shaft, the round
and square hole ee and the keys e' are used as before.
Radial and end wood screws can also be used and the nut i or a cottar pin as at u
in Fig. 9. or other device applied to attach the cap to the shaft.
Fig. 5 shews a modification in which the screwed shafts is dispensed with, this
form being used for rollers not subject to heavy strains. A short shaft / is cast
with or otherwise secured to the cape which is provided with the keys e¹ and e³ as
before and is preferably forced on to the roller under pressure.
In some cases the shaft is not required and I then make the boss e of suitable
length and diameter and turn it up outside to serve as a journal. In some case no
journal is required and then the end of the cap is closed as shewn by dotted line m.
Fig. 6 shews a form of cap made and secured in accordance with my present
invention having an outer rim e enlarged and turned up as is sometimes required
to run in bearings.

page_text: Fig. 7. shews in front elevation and Fig. 8 in side elevation a method of attaching
a movable flange for weaver's, warper's, and other beams. The boss n' cast or
formed with the flange n has one half of it cut away for a depth o. and this portion
is replaced by a loose cap p..secured by bolts q. q. but arranged with a clearance ?
so that the beam will be clipped by the cap when the bolts g are tightened. The
diameter t is bored out to the correct diameter of the working part of the beam or
roller. One or two such movable flanges can be used on one roller.
Fig. 9 shews a roller of a mangling or wringing machine constructed according to
my present invention. The roller being secured to the shaft / by the caps e or e³,
e being shewn as an exterior cap and e¹ as a sunk cap. The shaft may be secured
end ways by a pin u or by the device v known as a "circlip."
Having now particularly described and ascertained the nature of my said
invention and the manner in which it is to be performed I declare that what I
claim is :-
1. In rollers for machines the screwed centre shaft having sharp "V" threads
substantially as and for the purposes hereinbefore described and illustrated in the
accompanying drawings.
II. In connection with rollers for machines a round and square hole through the
cap substantially as and for the purposes hereinbefore described and illustrated in
the accompanying drawings.
III. In connection with rollers for machines longitudinal and cross tapered keys
formed inside the cap substantially as and for the purposes herein before described
and illustrated in the accompanying drawings.
IV. In connection with rollers for machines the enlargement in diameter of a
portion of the ruffle to receive radial screws substantially as hereinbefore described
and illustrated in the accompanying drawings.
V. In connection with rollers for machines the cap formed with internal keys
and pressed into position under great pressure substantially as hereinbefore
described.
VI. In connection with rollers for machines the cap formed with a boss and
having a short shaft cast with it substantially as and for the purposes hereinbefore
described and illustrated in the accompanying drawings.
VII. In connection with rollers for machines the cap with boss formed upon
it and turned to serve as journal substantially as hereinbefore described and
illustrated in the accompanying drawings.
VIII. In connection with rollers for machines the cap formed and secured by any
of the methods hereinbefore described and provided with an enlarged outer flange
to serve as journal substantially as hereinbefore described and illustrated in the
accompanying drawings.
IX. The movable flange with cap to grip the roller substantially as and for the
purposes hereinbefore described and illustrated in the accompanying drawings.
X. The cap for mangle rollers secured as hereinbefore described and substantially
as illustrated in the accompanying drawings.
Dated this 14th day of March 1892.
