Improvements in Baking Tins.
I, EMILY CONSTANCE MCARTHUR Riversmeet Topsham Devon 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 object of my invention is to provide a baking tin or like cooking utensil with
simple and efficient means whereby a piece of meat or other article of food being
cooked shall be automatically basted, or the liquid, gravy or juices issuing from
the meat shall, by mechanical means, be continually poured over it whilst cooking,
-in lieu of periodical basting by hand as heretofore, with the resulting advantage
of perfectly or properly cooked food.
In accordance with my invention I form the floor of the cooking tin or like
utensil with a channel or groove to drain all the liquid or gravy to one point. At
such point I arrange a cylindrical chamber, and within such chamber, which
extends below the floor of the tin and forms a well for the accumulation of the
liquid, I place a nump. This pump is operated by clock-work mechanism, and
serves to force the liquid up a tube or pipe to a distributing point or nozzle, where
it flows over a plate or spreader on to the meat beneath it in the tin.
And in order that my said invention may be more readily understood and
carried into practical effect, I have hereunto annexed 2 sheets of drawings
illustrating my invention, and will now proceed to describe the same with the
figures and letters of reference marked thereon.
On sheet one, Fig. 1 is a part plan of a baking tin with my invention applied
thereto.
On sheet two, Fig. 2 is a transverse vertical section of Fig. 1 on line x-x.
Fig. 3 is a front detail view.
In each view (A) is the baking tin or tray, with floor (B) raised a sufficient
height to enable the lower end of cylindrical casing or chamber (C) to lie below it
and form a well for the reception of the gravy or other liquid drained into it by
channel (D) formed in the said floor (B).
Within the casing (0) I arrange a pump (E) with foot or non-return valve (F).
The piston (E) of this pump is connected by rod (G) to a crank shaft or axle (H),
supported in a suitable frame (I). Upon this crank axle is a pinion (J) with
which gears a spur wheel (K) on shaft (L) above. Upon shaft (L) is another
pinion (M) with which gears the spur wheel (N) upon winding shaft (O): Upon
this latter shaft I mount one or more strong coiled springs (P).
To the lower end of the pump cylinder I connect a pipe or tube (Q) which
extends upwards (by preference) within the casing (C), and terminates at a point
near the top end thereof, where it either spreads out into a wider tube, or is fitted
with a distributor plate (R) set at a slight angle towards the meat in the tray.
In starting to use the appliance, the joint or fowl to be cooked with the usual
preparation of lard for basting, is placed in the tin beneath the plate (R). When
basting is to commence (or previously) the springs (P) are wound up by a key
applied to the end of shaft (O). The recoil of the springs then sets the train of
wheels (J), (K), (M) and (N) in motion, and in turn operates shaft ( ) and pump,

page_text: piston (E) which latter serves to force the gravy or liquid, as it drains into the
casing (C) up the tube (Q), and over the plate (R), from whence it falls on to the
joint in the tin, and so on continuously until the joint is cooked, or until the
reccil of the springs is exhausted, the strength of springs being such as to allow
ti.em to run for a lengthened period without re-winding.
To regulate the flow of liquid, or degree of basting, I provide a tap (T), which
also serves to retard or quicken the speed of pumping. To prevent the liquid
running back at each return, stroke of the pump piston I provide a valve (V) in
the length of the pipe (Q).
Having thus 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:
1. A baking tin or like cooking utensil, fitted with means for elevating the
juices or liquid collected from the joint or other article being cooked, and delivering
such juices or liquid over the said joint, substantially as set forth.
2. The combination of baking tin (A), casing (C), pump (E), wheels (J), (K),
(M), (N) and shafts (L), (0) and (H), springs (1) and tube (Q) with plate (R)
(or its equivalent), and valves (F), (V), as and for the purposes set forth.
