COMPLETE SPECIFICATION.
Improved Apparatus for Cleaning Baking-plates.
I FREDERICK WILLIAM GOLBY of 36. Chancery Lane, in the County of
Middlesex, Patent Agent do hereby declare the nature of this invention as
communicated to me by Johannes Eixmann junior of Lubeck, Germany, Baker,
and in what manner the same is to be perforined, to be particularly described and
ascertained in and by the following statement :--
The object of this invention to provide an improved apparatus for scraping and
cleaning bakers'-plates in a convenient and speedy manner.
The cleaning apparatus consists of an outer or surrounding case or body and an
inner oil-reservoir fitted within the said case and having a valve which opens by
pressure acting from above so as to allow the oil to flow on to the plate to be
cleaned, where it is subjected to a rubbing action by the aid of a rubbing-plate or
the like.
In order to remove from the baking-plate the solid impurities which adhere
thereto, the casing is provided with a scraping-plate under the pressure of a spring
or cushion and brought into the operative position by the pressure of the finger.
This invention is represented in the accompanying drawings of which
Figures 1 and 2 are vertical sections taken at right angles to each other.
Figures 3 and 4 are respectively side and front elevations, and
Figure 5 is a perspective view of the complete apparatus.
The same letters of reference are used to denote the same or corresponding parts
where they occur.
e.
C,
The casing a consists of a block of wood suitably hollowed out at the sides and
carrying inside a sheet metal reservoir closed at the bottom by a valve and
having a vaulted top d, and a lateral inlet pipe The block of wood a is open
below and at the top d. Close below the said vaulted top d is the upper end of a
rod carrying a knob or enlargement, the said rod being guided through the
reservoir 6 by cross stays g g'. The lower end of said rod rests upon the valve c,
which is forced up against the seat or lower end of the reservoir by means of a
spring h. A rubber-packing c¹ serves to tighten the joint between the reservoir
and valve. The lower surface of the block a projects over the valve and is lined or
faced with a rubbing plate i.
The apparatus as before described serves to oil and clean baking-plates, the
operation being carried on in the following manner; the operator places his hand
under the handle k of the block a and moves the apparatus over the surface of the
plate to be cleaned. By applying a slight pressure of the finger on the vaulted
top d the valve c c is opened by means of the rod and a certain quantity of oil is
discharged from the reservoir 6 to the plate where it is distributed by the rubbing
surface i of the block. The spring / returns the valve c c¹ to its seat as soon as the
pressure of the finger is released from the vaulted top d.
With the cleaning or rubbing device, as described is combined a scraper to remove
the solid impurities adhering to the baking plate; said scraper being constructed
as follows.
On one side of the wood block a two guide plates are secured, between which
a sliding-plate m is arranged to be reciprocated. The lower part of said plate is
enlarged to form a scraper m' and its central part is slotted to receive a cylinder n
secured by arms oo to the guide plates as shewn in Figures 4 and 5. In the
cylinder n is loosely fitted a second cylinder p connected to the sliding-plate m by a
cross stay g.
A spiral spring is arranged within the two cylinders tending to force
the sliding cylinder out of the fixed cylinder and to hold it in its upper position.

page_text: In being forced upward, the scraping plate m' bears against the lower end of the
guides and arms o o and prevents the loose cylinder p from being thrown out of
the fixed cylinder n. In this position of the scraper m³ the sharp lower edge of the
same is slightly raised above the lower surface of the block a in order to prevent
the edge of the scraper from coming into contact with the baking-plate during the
oiling and scraping operation, even if the rubbing surface i is reduced by wear anl
tear.
If scraping is desired to be performed the stay q is depressed by the operator's
finger and accordingly also the scraper m' so that the edge of the scraper projects
below the surface of the rubbing plate and removes the solid impurities on the
surface of the baking-plate.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. An apparatus for cleaning baking-plates consisting of a casing a containing
an oil reservoir b, the open bottom of which is closed by a spring-actuated valve cc'
which opens under pressure applied from above, so that oil can be discharged upon
the baking plate through such valve and rubbed there by the rubbing plate i secured
to the underside of the block or casing a substantially as described and illustrated.
2. An apparatus for cleaning baking plates consisting of a casing a, an oil
reservoir 6 therein contained, a valve c c to close the bottom aperture of the said
reservoir and adapted to open by pressure from above, and a scraper m² to remove
the solid impurities, said scraper consisting of a sliding plate m¹ retained in its
upper position during the rubbing operation, and forced down to act as a scraper,
when desired, substantially as described and illustrated in the accompanying
drawings.
Dated this 16th day of April 1894.
