Complete Specification Left, 28th May, 1897-Accepted, 3rd July, 1897
JESSE MILLER DAVID MILLER EDWARD MILLER Tin and Iron plate Workers all of
4 High Cross Street Leicester in the County of Leicester do hereby declare the nature
of this invention to be as follows:-
Our invention consists in a revolving turn table in Oven bottoms and shelves on
which articles to be cooked are placed. We construct a plain or studded plate "a"
(out of cast iron or other materials suitable) with bevelled cog wheel underneath,
revolving in oven bottom or shelf "66" through contact with bevelled cog wheel "c,"
turned by detachable handle "e" inserted through hole in front of oven or range,
and connected by spindle fixed in cog wheel "c" and passing through hollow tube
"d" and fixed to oven bottom or shelf by bearer "f" the circular plate "a" working
on shouldered pin "h" through bearer "f," the whole being covered by a dust and
smoke proof cover "j." If considered necessary dotted line "g" shows section of
oven and "i" oven door. The above invention is for convenience of turning articles
round, prevention of burning the hands, or allowing heat to escape-during the pro-
cess of cooking, from range or any description of oven-without opening the door,
also to enable bakers ovens to be filled and emptied with greater facility.

Improvements in and relating to Oven Bottoms and Shelves.
We, JESSE MILLER, DAVID MILLER, and EDWARD MILLER all of 4, High Cross Street,
Leicester, Tin and Iron Plate Workers 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 relating to ovens has for its object to enable the oven bottom or
shelf or shelves to be rotated without it being necessary to open the door for that
purpose.
The rotation of the oven bottom or shelf will allow different sides of the article
thereon to be alternately placed next to the hottest part of the oven and thus enable
the said article to be more uniformly cooked or baked than would otherwise be
possible.
It will also permit bakers to remove from the oven the first batch of bread, cake,
pastry or the like placed therein without it being also necessary to remove those sub-
sequently inserted, and the fact that these operations can be performed without the
[Price 8d1

page_text: opening of the door is a valuable consideration in the baking of pastry and the like
where it is essential to provide against a reduction of the temperature while the
baking is going on.
The present invention comprises a rotatable oven bottom or shelf or shelves and
mechanism for rotating the same actuatable outside the oven.
The invention will be understood from the following further description having
reference to the accompanying drawing wherein,
Figure 1 is a view in transverse section of a revoluble oven bottom or shelf and its
seating and dust cover and one form of mechanism applied thereto for rotating the
shelf without opening the oven door.
Figure 2 is a plan of the underside thereof with the dust cover removed.
Like letters of reference represent the same parts throughout the drawings.
A represents a circular shelf or the bottom of an oven (hereinafter referred to as a
shelf) which may have a plain surface A¹, or a studded surface A² as desired.
The marginal edge A³ of the underside of the shelf may be reduced in thickness as
shown and rest in a seating B correspondingly formed and attached to the sides of
the interior of the oven or to the bottom thereof.
Openings B may be made at intervals in the seating and rollers B³ may be
rotatably pivotted therein or other antifriction devices may be employed to render
the motion of the shelf smooth and easy.
On the underside of the shelf there may be fixed by a screw C¹ passing into a bar
E or other means a horizontal bevel wheel C gearing with a similar wheel D mounted
on a spindle D' passing through an opening in the front F of the oven to the outside
of the latter where it terminates in a square head adapted to receive a detachable
enk handle ( by which motion may be communicated thereto.
Intend of the handle a small wheel may he fixed on the spindle D¹ by which to
operate the latter.
The spindle passes also through a lug H secured to the underside of the seating by
bolts H, through the tubular part of the bearer E, across the space formed therein
by the cranked portion E¹ and into the opposite part of the bearer as shown in
Figure 1.
The other extreme end of the bearer is supported in a lug or angle plate H², bolted
at H³ to the underside of the seating as shown.
The whole of the working parts may be enclosed by a dust or smoke proof cover J
as illustrated and screwed at J¹ Figure 1 to the underside of the seating.

Although the invention is shown in the annexed drawing as applied to the bottom
of, or lowest shelf in, the oven, it is obvious that in cases where a number of shelves
are superposed or arranged in tiers, as in baker's ovens constructed on the "decker
system, the motion could be communicated to the upper shelves by repetitions of the
mechanism hereinbefore described, or the shelves could be so arranged that a single
actuating mechanism would be sufficient to simultaneously rotate them.
In one obvious modification on the latter principle the various shelves could be
connected by a square vertical spindle (instead of the screw C¹) passing through a
square opening central in each of the whole of the shelves, in which case any motion
of the bottom shelf would be communicated to those above it.
When desired a glass inspection opening may be placed in the door so as to allow
the contents of the oven to be viewed and the baking progress ascertained without
opening the door.
The invention is not limited to the precise mechanism for revolving the shelves
hereinbefore described although it is found suitable and convenient for the purpose
indicated.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is :-
1. In an oven the combination with a revoluble shelf or bottom of mechanism for
rotating the same for the purpose described.

page_text: 2. An oven provided with two or more revoluble shelves, one above the other
arranged in such a manner that the motion of the one is communicated to the other
or others and mechanism for rotating one of the said shelves for the purpose
described.
3. In an oven the combination with one or more rotatable shelves of a bevel wheel
fixed to one or each of the same and gearing with a similar wheel mounted on a
spindle actuated by a crank handle or other means for the purpose described.
4. In an oven the combination of a revoluble shelf such as A its seating B, gear
wheels CD, spindle D¹ and crank handle G or its equivalent substantially as described.
5. In an oven the combination of a revoluble shelf and mechanism constructed,
arranged and operating substantially in the manner and for the purpose described and
illustrated in the accompanying drawing.
Dated this 27th of May 1897.
