Improvements in Locking and Friction-reducing Devices Applicable
for Washing, Wringing, and Mangling Machines.
I, HENRY CROFTS LONGSDON of Keighley in the County of York Machine Maker
do hereby declare the nature of this invention to be as follows, that is to say :-
It consists of improvements in locking and friction-reducing devices applicable for
washing wringing and mangling machines by the employment of which, accidents and
breakages are prevented, and the manipulation of the machines is facilitated.
The locking device consists of means for locking or fastening the motor parts of
the machine when same are not in use, so that accidents to children or inexperienced
persons may be prevented.
This is obtained by mounting on any appropriate part of the hand or winch-wheel,
suitably shaped screw which when rotated moves into (when locking said machines)
or out of an opening made in any fixed article or part of the machine, with the effect
which will readily be seen.
A suitable projection or shield is formed on the winch wheel around the outer or
headed end of the above named screw to prevent same from catching anything as
articles of dress, etc., when in motion.
Respecting one friction-reducing device this invention consists of applying anti-
friction rollers for connection with some of the motor parts of said machines the same
having heretofore operated in connection with parts relatively (in one particular
direction) at rest.
This relates to the application of an antifriction roller to the upper end of each of
the dies or moveable blocks of the machine, so that the springs which impart pressure
to the machines' pressing rollers, and which have a short lateral as well as a down-
ward movement, may rest upon said antifriction rollers, by which means the breakages
of said dies, incident to the outward pressure caused by said lateral movement
and friction of said springs, which in this class of machine acts in direct contact with
said dies, are avoided.
The other friction-reducing device consists of the application of antifriction rollers
for the shafts of the machines' pressing rollers, by which means the manipulation
thereof is facilitated

page_text: This is attained by forming or rigidly attaching an appropriately shaped hoop on
or to one side of each of the hereinbefore named "dies" or blocks, when in connection
with the top rollers, and on or to one side of each of the end frames of the machine
when in connection with the bottom rollers, a similar hoop being arranged to be
loosely attached to the other and opposite side of each of said dies or end frames
respectively. On the outer edge of each of these hoops is formed a suitably pro-
portioned flange at about right angles to the flat surface of said hoops. From this it
will be seen that when both these hoops are attached to a "die" or to one of the end
frames, a suitable receptacle and guide for antifriction rollers, is formed; the loose
hoop being employed to allow the insertion of a suitably shaped metallic disc which
has notches made in its periphery for the reception of all the antifriction rollers used
in the receptacle formed in each die, a separate notch for each roller.

for Washing, Wringing, and Mangling Machines.
I, HENRY CROFTS LONGSDON of Keighley in the County of York, Machine Maker
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 that is to say :-
:
It consists of improvements in locking and friction-reducing devices applicable
for washing, wringing and mangling machines by the employment of which, accidents
and breakages are prevented, and the manipulation of the machines is facilitated.
In order that my said invention may be more readily understood I have hereunto
appended sheets of drawings illustrative thereof, to which, by figures and letters,
reference is made in the following description.
Figs. 1 and 2 are end and side views respectively of such portions of a machine as
will be sufficient to illustrate the locking device.
Figs. 3 and 4 are similar views to figs. 1 and 2 respectively, but illustrate the
friction reducing devices.
Figs. 5, 6, 7, 8 and 9 are detail drawings enlarged scale hereinafter referred to.
Similar letters and figures refer to similar parts throughout the several views.
A indicates the ond frame of the machine.
The locking device consists of means for locking or fastening the motor parts of
the machine when same are not in use, so that accidents to children or inexperienced
persons may be provented.
This is attained by mounting on any suitable part of the hand or winch-wheel a
(such as on its arm a¹) an appropriately shaped screw b, which when rotated moves
into (when locking said motor parts) or out of (as when said parts are to be free)
an opening made in any fixed article or part of the machine, such as into the end of
the stud c.
A suitable projection or shield a² is formed on the arm a¹ around the outer or
headed end of the screw to prevent same from catching anything such as articles of
dress etc. when it is unscrewed or rotated to liberate the motor parts and said motor
parts are put into operation.
Respecting one friction-reducing device this invention consists of applying anti-
friction rollers for connection with some of the motor parts of said machines, the
same having heretofore operated in connection with parts relatively (in one particularly
direction) at rest.
This relates to the application of an antifriction roller to the upper end of each
of the dies or moveable blocks e, so that the outer end of the spring which imparts
pressure to the rollers g g', and which (said spring f) at this part has a short laterai
movement somewhat in the direction shewn by arrow h as well as a downward

page_text: movement, may rest upon said roller d by which means the breakages of the dies e,
incident to the outward pressure caused by said lateral movement and friction of said
springs (which in this class of machine is in direct contact) with the dies e, are
avoided.
The other friction reducing-device consists of the application of antifriction rollers
for the shafts of the rollers g g¹, by which means the manipulation of the machine is
greatly facilitated.
This is attained by forming on or rigidly attaching an appropriately shaped hoop e¹
to one side of each of the hereinbefore named dies or blocks e, when this friction
reducing device is used in connection with the top roller g, and on or to one side of
each of the end frames A when in connection with the bottom roller g¹, a similar
hoop being arranged to be loosely attached to the other and opposite side of each
of said dies e or end frames A respectively, see figs. 4 and 5.
On the outer edge of each of these hoops e¹ and e² is formed a suitably proportioned
flange eat about right angles to the flat surface of said hoops e¹ and e².
From this-it will be seen that when both these hoops e¹ and e² are attached to a
die e or to one of the end frames A, a suitable receptacle and guide for the anti-
friction rollers k, is formed; the loose hoop e being employed to allow the insertion
of a suitably shaped metallic disc or annular piece of metal which has notches made
in its periphery for the reception of the necks formed about the middle of each of
the antifriction rollers k.
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 :
1. The screw the wheel a having an arm a¹ upon which is formed a circular
projection a², and the part e in combination all being arranged to operate in the
manner and for the purpose substantially as specified.
2. The bowl & mounted as shewn, the spring fand the block e constructed as
described, in combination the same being arranged to operate in the manner and for
the purpose substantially as specified.
3. The block e having the part e¹ attached thereto, the part e² constructed as
described, the rollers k and the ring in combination the whole of which are
arranged to operate in the manner and for the purpose substantially as set forth.
4. The frame work A, the parts e¹ and e² constructed as described, the rollers k and
the ring in combination, same being arranged to operate in the manner and for the
purpose substantially as set forth.
