PROVISIONAL SPECIFICATION.
Improvements relating to Washing Machines.
We, EMILE LEON THEOPHILE CARON JULIUS FERDINAND STANISLAUS CARON and
AMELIE ELIZA PAULINE CARON trading as Caron & Co. of St. Peters Street Old
Radford, Notts. Laundry Engineers, do hereby declare the nature of this invention to
be as follows:-
Our improvements relate to washing machines having a rotating motion and
generally a cylinder rotating within a protecting casing. As at present constructed
such machines are only utilizable for washing, boiling and rinsing, and when these
processes have taken place, the articles operated upon have to be removed and placed
in another machine to undergo the wringing or hydro-extracting process. Now, this
removal thus necessitated of the articles, involves not only a loss of time and loss of
labour; but, the articles being removed from one machine to another in a wet and
heavy state are more liable to injury by tearing.-Our Invention is therefore devised
with a view to overcome the disadvantages above pointed out. In carrying out said
Invention we construct and strengthen the usual washing machine cylinders or cages
so as to enable them to withstand the centrifugal force necessary for extracting or
wringing. We also add to the usual existing slow driving gear the high speed driving
gear necessary for extracting moisture by centrifugal force. Thus, by means of the
combination arrangement of parts in accordance with our Invention we are enabled, to
ensure that ordinary rotary washing machines which at present can only be used as
boilers and rinsers may also be utilized for the wringing or hydro-extracting
process.

Improvements relating to Washing Machines.
We, EMILE LEON THEOPHILE CARON, JULIUS FERDINAND STANISLAUS CARON, and
AMELIE ELIZA PAULINE CARON, trading as Caron & Co. of St. Peters Street, Oll
Radford, Notts. Laundry Engineers, 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 :-
Our improvements relate to washing machines having a rotatory motion and generally
a cylinder rotating within a protecting casing. As at present constructe such
machines are only utilizable for washing, boiling and rinsing, and when these processes
have taken place, the articles operated upon have to be removed and placed in another
machine to undergo the wringing or hydro-extracting process. Now, this removal of
the articles, thus necessitated, involves not only a loss of time and loss of labour, but
the articles being removed from one machine to another in a wet or heavy state are
more liable to injury by tearing.
Our Invention is therefore devised with a view to overcome the disadvantages above
pointed out. In carrying out our said Invention we construct and strengthen the
usual washing cylinders or cages so as to enable them to withstand the centrifugal
force necessary for extracting or wringing. We also add to the usual existing slow
driving gear the high speed driving gear necessary for extracting moisture by centri-
fugal force. Thus by means of the combination or arrangement of parts in accordance
with our invention we are enabled to ensure that ordinary rotary washing machines

In order that our Invention inay be thoroughly understood we have appended the
accompanying drawings.
Figure 1 is a sectional elevation of our improved washing machine, in which
the driving shaft and the end support or pluminer block of the shaft of the washing
and wringing cage are omitted.
Figure 2 is a plan and Figure 3 is an end elevation of our improved washing
machine.
Figure 4 is an end elevation of the washing and wringing cage.
In these drawings similar letters of reference indicate corresponding parts.
A is an iron casing which is made of such a size as to contain the washing
and wringing cage B and is constructed of sufficient strength to withstand a low
steam pressure, which may be regulated by a reducing valve or safety valve.
B¹ is a shaft which carries the washing or wringing cage B and projects through
stuffing boxes and glands B2 at each end of the machine. One end of the shaft B¹
is prolonged so as to carry friction cones C and D or other suitable fast and slow
speed gear such as toothed wheels and pinions, belts and pulleys or worm
gearing.
The prolonged end of the shaft B₁ turns in plummer block bearings B³. In
the larger machines a plummer block bearing would also be provided at the other or
feeding end of the machine.
The machine is driven by means of a belt and a fast pulley G, a loose pulley G'
being provided for stopping the machine. The pulleys G and G² are carried by
a driving shaft G2 which is supported by plummer blocks_G³. The shaft G² also
carries a large friction cone E and a small friction cone F. The friction cone E
drives the friction cone when the machine is to be run at a high speed, and
the friction cone F drives the friction cone when the machine is to be run at a
low speed, a sliding clutch G being placed between the friction cones E and F
to give motion to either of them according to the speed at which the machine is
to run.
Instead of the above described arrangement of fast and loose pulleys the shaft G2
may be provided with three pulleys and open and crossed belts with other apparatus
may be employed for reversing the direction of rotation of the machine.
The washing and wringing cage B is strengthened by rings a which pass completely
round its periphery, as shown in Figure 1, and by strong bosses b, 6' at its ends..
The boss 6 which is near the cones Cand D is conically bored and fits a correspondingly
coned part 2 of the shaft B', the boss b being caused to grip the coned part 2 of the
shaft B' by means of a screw and tightening nut b³.
The washing and wringing cage B, as shown in Figure 4, is divided into four com-
partments, each of which is provided, with a hinged door O and fastening Q. The
object of dividing the washing and wringing cage B into compartments is to ensure
that there shall be, as nearly as possible, an equal weight of material on each side of
the same, so that the weight shall be balanced and the strain upon the shaft B' and its
bearings equally distributed. In order to attain this object the cage B may be
divided into three or any other number of compartments, the number being dependent
upon the class of goods to be washed and the convenience of feeding and discharging.
The doors O are situated at the ends of the washing and wringing cage B to avoid
great pressure being exerted on them, when used for extracting the moisture, for the
centrifugal force would be liable to seriously damage them if they were situated in the
circular part, as is usually adopted in washing machines of this class.
Two doors are fitted to the casing A to allow two compartments of the
washing and wringing cage B to be emptied at one time without moving the cage.
The doors I are provided with hand wheels J and tightening screws J' which pass
through a horizontal bar K and engage with screws cut therein. By means of the
hand wheels J, the tightening screws J₁ and the bar K the doors I are rendered steam
tight.

page_text: Water cocks are placed at L and M to test the height of the water used in
washing.
We wish it to be understood that we do not bind ourselves to the exact arrangement
of machine shown as we may considerably vary the details. For instance the two
speeds could be obtained by other gearing than that shown, as herein before mentioned,
and the mode of fastening the doors could be varied.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
First In washing machines of the kind described herein providing the cage
thereof with strengthening rings running completely round the circumference and
with the arrangement of conical boss and nut and doors in the end of the cage,
substantially as and for the purpose described herein and illustrated by the accom-
panying drawings.
Second: In a combined washing and wringing machine of the kind described
herein providing the same with a two speed gearing substantially as described
herein.
