Improvements in or relating to Apparatus for Cleaning and Greasing
Baking and like Plates.
I, HEINRICH RÖDIGER, Master Baker, of 2, Marktstrasse, Zossen, in Prussia,
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:-
The present invention relates to apparatus driving by a motor or by hand for
the purpose of cleaning and greasing baking and like plates without loss of time
and without great trouble, and to facilitate and simplify the operation which if
it is to be carried out on a large scale requires the employment of many hands.
The essential and characteristic feature consists in the arrangement of a number
of cylinders, say four, one of which is provided with a number of movable or
adjustable scraping knives, which knives scrape the plates clean, the second
device brushes them clean, while the third applies a quantity of grease which is
spread over the plates by the last brush cylinder.
In the accompanying drawings, the invention is represented by way of
example:
Figure 1 being a longitudinal section;
Figure 2 a cross section through the whole machine.
Figure 3. is a plan view of the knife cylinder, and
Figure 4 a section through the same.
On
On the frame a and beneath the top or cover plate of the same are arranged
four cylinders c, d, e, and f, which are provided on one side with pulleys r.
the first roller or annular shaft c are a number of knives or scrapers p, broad
scrapers being preferably arranged at the centre and narrower ones towards the
sides, in order to accommodate various sized plates. The knives are adjustably.
arranged on guide rails s which secure them to the shaft. At the ends of the
shaft are arranged spiral springs q which press the knives always toward the
centre. The second shaft d is provided with hard bristles, the third shaft is
provided with only one strip of soft bristles which dip at each revolution of the
shaft into the fat or grease contained in a box arranged under the shaft. The
last shaft is provided with two broad strips, diametrically opposite to each other,
of soft bristles. Between the pulleys r rollers are arranged on hangers d at a
convenient height over which a cord h passes, driven by the driving wheel g in
combination with the rollers r. On the top of the apparatus are arranged two
bars carrying on pins o a rail n which is pressed downwards by spiral springs m.
The baking plate K (Figures 1 and 3) to be treated is first laid on the scraping
cylinder c and then pushed slowly under the first rail n, and above the cylinders
which are actuated by a very quick movement of rotation. Owing to this
arrangement the knives p scrape the plate clean and anything that may have been
left on them is brushed away by the bristle cylinder. The cylinder e provides
the grease and the brush f distributes the grease over the surface of the plate.
If there be any turned up edges on the plates that are placed between the knives p
they are placed between two adjacent scraper sections, as shown in Figure 3,
the springs q closing the knives after the plate has been removed.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
:-
1. Apparatus for cleaning and greasing baking and like plates characterized
by a series of cylinders of which the first scrapes the plate, the second brushes
it, the next applies grease to it, and the last distributes the grease upon it.
2. Apparatus for cleaning and greasing baking and like plates substantially
as described or illustrated in the accompanying drawings.
