Improvements in or relating to Apparatus for Wringing and
Mangling Clothes, Linen, and the like.
FREDERICK GEORGE HARBORD 108 Spring Field Terrace Crookes, Sheffield
Engineer, do hereby declare the nature of this invention to be as follows:-
In the construction of this machine I fit each roller in the usual way viz. :-On a
square shaft but keep it square throughout excepting the parts working in the
bearings. Both rollers are driven by means of bevel or mitre cogged wheels, each
of which is geared with a corresponding bevel or mitre cogged wheel revolving on
a vertical square shaft, this method of gearing renders the use of "keys'
unnecessary by preventing the possibility of the inner wheels slipping.
"
The upper pair of geared wheels rise & fall with the pressure & according to
the thickness of the material passing through the rollers. To effect this I fit the
driving cogged wheel of the upper pair loosely on its square shaft & by means of a
projecting crown together with the friction in working, the two wheels are kept
constantly in gear whatever the position on the shaft. This vertical driving shaft
works in two suitable brackets which I attach either in the casting or by means of
nuts & screws or otherwise to the upright metal side framework of machine. The
top bracket may be attached to the top cross frame or fixed in any convenient
position at or near the top of side support & the lower or under one at any suitable
distance below the other."
The upper bracket being easily removed & the wheels on both rollers being of
the same size & pattern allows of the interchange of rollers & the upper cogged
wheel on vertical shaft being fitted loosely on that shaft allows of the rollers
continuing in use after frequent skimmings down to rds or less of their original
diameters.
In any suitable position preferably below the lower pair of cogged wheels on the
vertical driving shaft I fix another wheel of larger diameter toothed either on the
circumference or on the outer rim of upper or under face of said wheel working
horizontally. This wheel being of large diameter gives great power & works
through an opening left in the upright framework & is revolved by means of a
double standard worm fitted and working on a shaft fixed in and at right angles to
the side framework of machine. This shaft also carries the flywheel which fits on
by means of a square boss or collar to a corresponding square shoulder on the outer
end of worm & is kept in position by the usual pin. On revolving the fly-wheel an
easy motion is communicated to the rollers.
I also introduce an arrangement of ball bearings between the inner shoulder of
worm & the boss to reduce the friction in working the machine forwards & between
the fly-wheel & the outer shoulder of worm in working backwards.
Dated this Fourteenth day of February 1902.

FREDERICK GEORGE HARBORD Engineer 108 Springfield Terrace Crookes
near Sheffield 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 :-
In the construction of this machine I fit each roller in the usual way viz.: on a
square shaft throughout excepting those parts which work in the bearings. Both
rollers are fitted at one side only with bevel or mitre cogged wheels A¹ A each of
which is geared to a corresponding bevel or mitre cogged wheel B' B revolving on
a vertical square shaft C thus rendering the use of keys unnecessary by preventing
the possibility of the inner cogged wheels A' A slipping. The upper pair of geared
wheels A Brise & fall with the pressure & according to the thickness of the
material passing through the rollers. To effect this I fit the upper driving cogged
wheel B loosely on its square shaft C & by means of a projecting crown D
together with the friction in revolving, the upper pair of wheels are kept constantly
in gear.
This vertical driving shaft C works in two suitable brackets E' E which I attach
either by means of nuts & bolts or otherwise to the upright metal side-framework F
of machine. The top bracket E' may be cast on to the top cross frame G or fixed in
any convenient position at or near the top of side framework F & the lower or
under bracket E fixed at any suitable distance below the other. The upper
bracket E being easily removed, & the cogged wheels A' A on both rollers being
of the same size & pattern allow of the interchange of rollers & the upper cogged
wheel B' being fitted loosely on the vertical driving shaft C allows of the rollers
continuing in use after frequent skimming down to 3rds of their original
diameters.
In any suitable position on the vertical driving shaft C preferably below the
lower pair of cogged wheels A B I fix another wheel H of larger diameter toothed
either on the circumference or on the outer rim of upper or lower face of said wheel
working horizontally through an opening left in the side framework F and is
revolved by means of a double standard screw or worm I fitted & working on a
shaft K attached at right angles to the framework F. This shaft also carries the
fly wheel L which is retained in position by the usual pin.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
"Improvements in or relating to apparatus for wringing and mangling clothes,
-linen and the like" conisting in
a. The employment of a pair of mitre cogged wheels of equal diameter for each
roller.
b. The employment of a vertical square shaft for carrying the driving wheel and
the outer cogged wheel of each pair named in "a" above.
c. The employment of a driving wheel of large diameter, toothed either on the
edge or on one of the faces, working horizontally.
d. The employment of a double standard screw or worm for revolving horizontal
driving wheel.
