PROVISIONAL SPECIFICATION.
Improvements applicable to Draw-plate and like Ovens.
I JAMES PRICE of 3 Princes Street, Bootle in the County of Lancaster
Foreman Baker, do hereby declare the nature of this invention to be as
follows:-
The invention relates to so called draw-plate ovens, or ovens with a metallic
frame or bottom which can be drawn out when the bread, biscuits, or the like is or
are baked so that the baked loaves or the like may be removed and a fresh batch
placed thereon after which the said metallic bottom is returned within the oven.
Owing to the oven bottom being at a high temperature, charging the said bottom
with a fresh batch of bread or the like, is trying for the attendants besides
occupying a long time and causing great waste of heat.
Now the object of my invention is to facilitate and expedite the charging of the
oven bottom or drawplate so as to save time and fuel besides rendering the work
more easy for the attendants.
For this purpose I combine with the said ovens a trolley, turntable, carrying
brackets and trays so made that the trolley may be readily run from oven to oven
with the said trays.
The trays are charged with the bread, biscuits, and the like, and the trolley is
capable of being turned into any required position so as to allow of the attendants
lifting the trays one by one and depositing their contents one after the other across
the said oven bottom.

COMPLETE SPECIFICATION.
Improvements applicable to Draw-plate and like Ovens.
I JAMES PRICE of 3 Princes Street, Bootle in the County of Lancaster,
Foreman Baker, 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, reference being had to the accompanying drawings:-
The invention relates to so-called drawplate ovens, or ovens with a movable
baking plate or bottom or ovensole which can be drawn out when the bread,
biscuits, or the like is or are baked, so that the baked loaves or the like may be
removed and a fresh batch placed thereon after which the said movable bottom or
drawplate is returned within the oven.
Owing to the oven bottom being at a high temperature the present method of
charging the said bottom with a fresh batch of hread or the like by lifting the
loaves one by one from the table and depositing them on the oven bottom, is trying

page_text: for the attendants, besides occupying a long time and causing loss of heat and also
imperfect setting.
Now the object of my invention is to facilitate and expedite the charging of
the oven bottom or drawplate so as to save time, fuel and labour besides rendering
the work more easy for the attendants and more exact.
For this purpose I combine with the said ovens, a trolly A carrying brackets B,
and trays T, so made that the trolly may be readily run from oven to oven with
the said trays.
The trays T are charged with the bread, biscuits, and the like P, and the
trolly A is capable of being turned into any required position so as to allow of
the attendants lifting the trays T one by one and depositing their contents across
or upon the said oven bottom or draw-plate D.
My invention may be applied also to travelling ovens i.e. ovens with continuously
movable endless webs forming the ovensole, and travelling from end to end through
the oven.
The shape and fittings of the trays TI prefer to use are shown on the drawing
Fig. 1, they are specially adapted for handling by two attendants one on either
side of the drawplate D Fig. 2. The hands C. C being shown holding on to the
handles H of the tray an idea may be formed of the jerking or shooting movement
the hands impart to the trays T through the handles H which are allowed to slide
gently through the hands C. C, against which they strike and are stopped when in
full swing, thereby causing the loaves P by the latter's inertia to glide from the
trays T and become deposited on the drawplate D. Two men can thus set by each
single movement one to three rows of loaves from the trays on to the plate.
I prefer to construct the trolly A so as to be capable of holding a full charge
for one drawplate, but two trollys might be used, and I also prefer to make the
trollys with brackets B on both sides but where room is scarce it might be
preferable to carry all the trays on brackets projecting on one side only of the
upright frame to obviate the necessity of turning the trolly round.
From the above it will be seen that the essence of my invention is the use in
combination with drawplate ovens and the like of a trolly or rack with trays on
which the prepared dough loaves can be set and arranged easily in the cold and
relatively to each other exactly in the position in which they are to be deposited
afterwards on the hot baking plate or travelling web.
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 :-
The combination and operation with drawplate and like ovens as aforesaid of
trollys carrying one or more trays, each tray capable of containing a number of
loaves to be deposited on the said drawplate or the like, substantially as and for
the purposes set forth.
