PROVISIONAL SPECIFICATION.
Improvement in Rotary Washing Machines.
[ JOHN PINKNEY, Engineer's Foreman, of Bloomsgrove Works, Nottingham do
hereby declare the nature of this invention to be as follows:-
My invention relates to that kind of rotary washing machines in which a wire cage
is arranged to revolve inside a steam tight casing, and the clothes or other articles to
be washed are placed in the interior of said cage. In this kind of machine a hinged
door easily made steam tight is arranged in the outer casing to give access to the cage,
and in the circumference of the revolving cage sliding doors are placed running in
grooves, the doors themselves having tongues or projections that slide in the.grooves.
The doors when in their working position form part of the circumference of the cage
and it is found in practice that the continual wear caused by the clothes or other
articles falling against the doors when they are in their lower position rapidly reduces
the thickness of the tongues on the doors or wears the grooves.
With the arrangement
of grooves hitherto used, it has been impossible to, repair or reline the tongues or
grooves without cutting out rivets or taking the cage to pieces. The object of my
invention is to remedy this inconvenience and my invention consists in constructing
the groove the doors slide in in such a manner that the doors can be removed and
replaced without having to take the cage to pieces.
For this purpose instead of cutting the groove in a solid bar or rim I form the outer
side of the groove by a bar screwed or removably attached to the inner part, so that
when the doors are in their mid position; this outer side or bar can be unscrewed and
removed. It can then he relined or the doors taken out and the tongues repaired with
facility, after which the doors and outer bar are replaced again. In this manner
repairs can be executed without having to take the cage out of the outer casing and
cutting out rivets as has previously been necessary.

Improvements in Rotary Washing Machines.
1 JOHN PINKNEY, Engineer's Foreman, of Bloomsgrove Works Nottingham in the
County of Notts. 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 invention relates to that kind of rotary washing machine in which a cage
covered with wires, bars or perforated sheets is arranged inside a steam tight casing
and the clothes or other articles to be washed are placed inside the cage and cleansed
by the rotation of the cage in the liquid and steam contained in the casing. In this
kind of machine a hinged door easily made steamtight is arranged in the outer casing
for giving access to the cage, and in the circumference of the revolving cage sliding
doors running in grooves are placed the doors themselves having tongues or projections
which slide in the grooves. When in their working position the doors form part of
the circumference of the cage, and it is found in practice that the continual wear
caused by the clothes or other articles falling against the doors when they are in their
lower position, rapidly reduces the thickness of the tongues on the doors and also
wears that portion of the grooves in which the tongues are when the doors are
closed and the inachine is in motion. With the arrangement of grooves cut in a
solid bar hitherto used it has been impossible to repair or reline these tongues without

having to take the cage out of the machine or to pieces. As the wear in the groove
is almost entirely confined to those parts in which the tongues of the doors rest when
the doors are closed, it is only necessary to construct these parts of the guides in this
manner. For this purpose instead of cutting, the whole of the groove in a solid bar
or rim as has hitherto been done, I for those parts where the doors rest in when closed
form the guides in such a manner that a part or parts of them are screwed or
removably attached to the other part fixed to the cage, so that when the former are
unscrewed and removed the doors can be taken out and the tongues and grooves
*repaired or relined with facility.
On the sheet of drawings appended hereunto
Fig. 1 shows au outside view of part of the cage with sliding doors and one
.arrangement of improved guides.

of fig. 3 of the improved guides on an enlarged scale Fig. 7 a top view and fig: 8.a
eross section of a modification of the arrangement.
:
A is the body of the cage shewn composed of bars à a inserted into circular end
rings aa. BB are two sliding doors composed of bars bb inserted into frames b¹.b²,
which are held together when the doors are closed by means of a catch-E. The door
fraines bare formed at their shorter, sides with tongues 5363 which slide in grooves
formed partly in the fixed guide.C, and partly in the removable, guides D D'. On-the
left side of fig. 3.the removable guide. Dis shewn in its working position and on the
right side the removable guide D detached for repairing or renewing:
.t
The guides D.D' are recessed at their backs to fit over the fixed guide C which is
-planed out, to receive them, as shewn by figs. 4 and 5 and are fixed to the same by
screws c.c² as shewn. When the doors are opened, these guides D D' can be taken off
for renewal or repair and the doors can then also be taken out and their tongues
relined, after which they are put in again and the guides I) D¹ fixed to the bar C.
Figs. 6 and 7 show a modified arrangement. The groove is in this case formed
by an inner or back part F and outer or front parts GG fixed to the former by
means of cover plates H H and screws ... This arrangement allows,the parts GG
which are chiefly subject to wear to be withdrawn or taken off after the screws
have been taken out, and renewed, while the doors can also be easily taken out for
repair of the tongues, without having to take the cage out of the casing or to cut out
rivets.
I do not confine myself to the details of the two arrangements hereinbefore
described which may be varied, but.
... Having now particularly described and ascertained the nature of my said invention
and in what inaoner the same is to be performed I declare that what I claim is
Constructing or arranging the grooved guides in which the doors of rotary washing
machine cages slide in such a manner that parts of said guides are removably attached
to other parts fixed to the cage and after removal of the detachable parts of the guides
the doors can be taken out without taking the cage out of its casing or the machine
to pieces, substantially as herein before described and illustrated by the drawings and
for the purpose set forth.
