Improvements in Washing Machines for Laundry and other purposes.

page_text: PROVISIONAL SPECIFICATION.
Improvements in Washing Machines for Laundry and other
purposes.
I, FREDERICK ALBERT SCHMIDT, of 94, Crowther Road, South Norwood, in the
County of Surrey, Engineer, do hereby declare the nature of this invention to be
as follows:-
My invention has reference to the increase of the capacity, the efficiency in
washing and the simplicity of loading and unloading of a rotary washing machine.
I construct an inner and an outer cylinder of wood or other suitable materials.
The inner cylinder is divided into two or more longitudinal compartments. Each
compartment is fitted with a press, which is hinged in a suitable manner to enable
it to alternately squeeze and release the articles being washed, and has a bracket
fitted with a pin and roller at one or both ends working in a groove in the end
plate or casting of the outer cylinder; or pins and levers or other suitable
mechanism which imparts to it the oscillation necessary to give the squeezing
effect on the articles being washed; or without hinges and working by the same
methods or by eccentrics or cams.
The inner cylinder is also fitted with one or more doors for loading and unload-
ing, which are furnished with springs in such a manner, that they act as spring-
boards where considered necessary, the springs being made of suitable material.
I also run a shaft or spindle through the centre of both cylinders, to add to
its strength and rigidity.
COMPLETE SPECIFICATION.
Improvements in Washing Machines for Laundry and other
purposes.
I, FREDERICK ALBERT SCHMIDT, of 94, Crowther Road, South Norwood, in the
County of Surrey, Engineer, 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 has reference to the increase of the capacity the efficiency in
washing and the simplicity of loading and unloading of a rotary washing machine.
Fig. I shews a cross section of the machine cut through the centre, but having
the three presses removed from the three lower compartments. Fig. 2, shews a
longitudinal section cut through the centre of the machine but having the press
removed from the lower compartment so cut through.

page_text: I construct an inner cylinder A, and an outer cylinder B of wood or other suit-
able material.
The inner cylinder A is divided into two or more compartments C, C, C³, C³, C4, C³.
Each compartment is fitted with a press, D, D¹, D2 which are hinged in a suit-
able manner to enable it to alternately squeeze and release the articles being
washed.
Each press has a bracket fitted to it with a pin and roller at one or both ends
working in a groove in the end plate or casting of the outer cylinder B, or pins
and levers, or other suitable mechanism as shewn in the drawing, viz.: With an
eccentric or eccentrics E and brackets F, F1, F2, with rollers G, G¹, G³, which
impart to the said presses the oscillation necessary to give the squeezing effect
on the articles being washed.
The eccentric or eccentrics E, remain stationary and the inner cylinder revolves
so that wherever the eccentricity of E occurs the squeezing takes place. To pre-
vent the presses from falling when coming round to the bottom of the outer
cylinder, the presses opposite one another are connected by a coupling rod I as
shewn.
The inner cylinder is also fitted with one or more doors H, H', H2, to each com-
partment for loading and unloading which may be fitted with springs in such a
manner as to permit them to give slightly when the presses squeeze the clothes
against them the said springs being made of suitable material. I also run a
shaft or spindle through the centre of both cylinders to add to its strength and
rigidity.
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 division of the inner cylinder of a rotary washing machine into two or
more compartments each compartment fitted with a press.
2. The oscillation of the presses by means of brackets, pins and rollers pins
and levers or eccentrics, brackets and rollers, or other suitable mechanism.
3. The construction of a door or doors to each compartment fitted with springs
to cause them to act as spring boards.
4. The fitting of a centre shaft through the inner and outer cylinders.
5. The combination of the separate compartments with presses fitted with and
worked by eccentrics or other suitable mechanism and strengthened by a centre
shaft these together with an outer cylinder and the necessary gear etc. com-
prising a rotary washing machine.
