Improvements in Machinery for Cleaning and Greasing Bakers' and
Confectioners' Tins.
I, FRITZ MÜLLER, of 102 N. Ackerstrasse, Berlin, in the Empire of Germany,
Baker and Confectioner, do hereby declare the nature of this invention to be as
follows:
-
This invention is designed to provide a machine for cleaning baking tins
after use. By the special arrangement of this machine it is possible to effect the
cleaning of the baking tins used by bakers and confectioners with the greatest
neatness, and a very considerable saving of time as well as to grease them so
that they can be used immediately without further handling
In consequence of the great variety of work which the baker and confectioner
has to perform, it is found that to keep the absolute and careful cleanliness
necessary in the management of the baking tins it takes a not inconsiderable
part of his working time; one is therefore compelled in order to make the best
use of the heat of the oven to undertake the cleaning of the tins a long time
before they are to be used, which is done at the loss of cleanliness as the tins
remain exposed to dust and the like until they are required for use. A further
disadvantage may be noted, namely that it is not possible to obtain the desirable
cleanliness with a scraping knife without a great loss of time.
My machine however effectively cleans the tins, even in most inaccessible
places in at most one tenth of the time hitherto required.
The invention will be described with reference to the accompanying
drawings;
-
Fig. 1, is a front elevation of the machine.
Fig. 2, is a section on the line -y of Fig. 1.
I construct the machine with an under frame A and a box B for the
mechanism, for the actuation of which a handle C is here shown. It may also be
driven by power. On the axle D of this handle there are fixed inside the box B
two adjustable chain wheels a likewise at the other end of the box are fixed
the two adjustable chain-wheels a¹. The endless conveyor chains c connect each
one of the front wheels with one of the back wheels.
The end of the axle D opposite to that of the handle C carries a chain-wheel a
for driving the roller by means of the chain-wheel a³. The rollers 61, 62, 63 in the
upper part of the box and placed one behind the other at proper distances
are actuated from the roller 63 by means of the chain wheels a and suitable chain
gearing.
The roller 6 which is the first to act upon the tin to be cleaned is the scraping
roller and is covered with a brush-like covering of steel wire which serves to
effectually remove all dirt, hard-baked dough, sugar and the like which adheres
to it.
The second or sweeping roller 62 by means of a suitable soft bristle covering
sweeps down into the drawer which is under the rollers any uncleanliness which
still remains whilst the third roller 63 into which butter grease or .other fat is

page_text: rubbed by hand or other suitable device makes the tin which is brought to it quite
clean, ready for use by smearing it with grease.
The tins are carried forward by means of suitable catches or projections i, two
on each of the conveyor chains c at equal distances apart.
The action of the machine is as follows: —
i
As soon as two of the pins of the continuously running conveyor-chains c
appear above the handle wheel, the workman stops the handle C, takes one of the
tins which is at hand ready to be cleaned and lays it on the conveyor chains
against the pins . The handle is now turned again, the pins pull the tin first
under the scraping roller 6 which revolving in the opposite direction to that
in which the tin is moving cleans it from front to back conveying away the
dirt into a drawer underneath the chains.
The second or sweeping roller sweeps in a similar manner all the dust
remaining on the tin into the drawer, whilst the third or greasing roller 63 effects
the requisite greasing of the tin. Behind the roller b³ the tin ready for use 18

Improvements in Machinery for Cleaning and Greasing Bakers' and
Confectioners' Tins.
I, FRITZ MÜLLER, of 102 N. Ackerstrasse, Berlin, in the Empire of Germany,
Baker and Confectioner, 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:-
This invention is designed to provide a machine for cleaning baking-tins after
use. By the special arrangement of this machine it is possible to effect the
cleaning of the baking-tins used by bakers and confectioners with the greatest
ease and a very considerable saving of time, as well as to grease them so that they
can be used immediately without further handling.
In consequence of the great variety of work which the baker and confectioner
has to perform, it is found that to maintain absolute and careful cleanliness in
the management of the baking-tius occupies a not inconsiderable part of his
working time; one is therefore compelled, in order to make the best use of the heat
of the oven, to undertake the cleaning of the tins a long time before they are
to be used, which is done at the loss of cleanliness, as the tins remain exposed
to dust and the like until they are required for use. A further disadvantage may
be noted, namely that it is not possible to obtain the desirable cleanliness with a
scraping-knife without a great loss of time.
My machine however effectively cleans the tins, even in most inaccessible
places, in about one tenth of the time hitherto required.
The invention will be described with reference to the drawings left with
the Provisional Specification.
Fig. 1, is a front elevation of the machine.
Fig. 2, is a section on the line x-y of Fig. 1.
The machine is constructed with an under frame A, and a box B for the
mechanism, for the actuation of which a handle C is shown. It may also be
driven by power. On the axle D) of this handle there are fixed inside the box B,
two adjustable chain-wheels a, likewise at the other end of the box are fixed

page_text: the two adjustable chain-wheels a. The endless conveyor-chains c connect each,
one of the front wheels with one of the back wheels.
The enu of the axle 1 opposite to that of the handle C carries a chain-wheel a
for driving the roller 63 by means of the chain wheel a³.
The rollers 61 62 63, in the upper part of the box B, and placed one behind the
other at proper distances, are actuated from the roller 6 by means of the chain
wheels a at the opposite end of the rollers, and suitable driving chain.
The roller 6¹ which is the first to act upon the tin to be cleaned is the scraping
roller, and is covered with a brush like covering of steel wire, which serves to
effectually remove all dirt, hard baked dough, sugar and the like which adheres
to it.
The second or sweeping roller 62 by means of a suitable soft bristle covering
removes and sweeps down into the drawer which is under the rollers, any adhering
matter which still remains, whilst the third roller into which butter grease or
other fat is rubbed by hand or other suitable device makes the tin which is
brought to it quite clean, ready for use by smearing it with grease.
The tins are carried forward by means of suitable catches or projections i, two
on each of the conveyor-chains cat equal distances apart.
The action of the machine is as follows:-
As soon as two of the pins of the continuously running conveyor-chains c
appear above the handle wheel, the workman stops the handle C, takes one of the
tins which is at hand ready to be cleaned and lays it on the conveyor chains
against the pins i. The handle is now turned again, the pins pull the tin first
under the scraping roller b¹ which revolving in the opposite direction to that
in which the tin is moving cleans it from front to back conveying away the
dirt into a drawer underneath the chains.
The second or sweeping roller sweeps in a similar manner all the dust
remaining on the tin into the drawer, whilst the third or greasing roller 63 effects
the requisite greasing of the tin. Behind the roller 63 the tin, ready for use, is
drawn away either by hand or by other suitable arrangement.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. A machine for cleaning baking-tins, in which the tins to be cleaned are
brought to a series of rollers by conveyor-chains or similar means, and which has
three different kinds of rollers in proper order for cleaning and greasing the tins,
so that the first serves as a scraper, the second as a sweeper, and the third as a
greaser substantially as described.
2. A machine for cleaning baking-tins having the several parts constructed and
arranged in combination substantially as described.
