OF PREDICATION.
An Improvement in Appliances for Raising and Lowering Cooking
Pans, Partly Applicable to Shelves of Ovens.
I, CHARLES CARR WILSON, of the firm of Charles Wilson & Sons, of Carlton Street,
Leeds, in the County of York, Gas Engineer, do hereby declare the nature of this
invention to be as follows:-
In many cooking operations the meat or article of food to be cooked, placed in a
pan under a gas or other burner or under or over the hot plate of an oven, is
subjected to the heat radiated upon it. In many cases it is necessary to adjust the
distance of the pan below or above the flame or hot plate and this is usually effected
either by placing packing pieces of various thicknesses under the shelf or pan so as
to raise it more or less, or by providing ledges at various heights on which to rest the
shelf or pan. Eeither of these methods involves trouble and inconvenience especially
in dealing with hot material.
This invention relates to simple and convenient means of adjusting the height of a
cooking pan or oven shelf by merely moving a little the oven shelf or the grating or
base plate on which the pan rests. In the case of a cooking pan this grating or base
plate is accommodated within a framing having its farther end suspended from the
framing by a radius link pivotted at each side and having its near end provided at
both sides with lateral pins which project into slots of the framing the lower edges of
these slots being made with several notches.
When it is desired to adjust the height of the pan which rests on the grating or
base plate, the near end of the plate is raised a little so as to disengage its lateral pins
from the notches in which they lie and then the plate is pulled a little forwards or
pushed backwards as the case may be, and as its two ends move in circular arcs it is
thus moved parallel to itself to a greater or less height as desired, and its pins being
then engaged each in another notch of the slot, the plate remains firm in position, the
pan which it carries being thus adjusted nearer to or farther from the flame or hot
plate above it.
For oven shelves, the inner end of the shelf is suspended by links from the sides of
the oven, and at the front end notched slots are formed in the sides of the oven into
which take pins on the sides of the shelf, the action being precisely the same as above
described.

COMPLETE SPECIFICATION.
An Improvement in Appliances for Raising and Lowering Cooking
Pans, Partly Applicable to Shelves of Ovens.
1, CHARLES CARR WILSON, of the firm of Charles Wilson & Sons, of Carlton Street,
Leeds, in the County of York, Gas Engineer, 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 :-
:-
In many cooking operations the meat or article of food to be cooked, placed in a
pan under a gas or other burner or under or over the hot plate of an oven is subjected
to the heat radiated upon it. In many cases it is necessary to adjust the distance of
the pan below or above the flame or hot plate and this is usually effected either by
placing packing pieces of various thicknesses under the shelf or pan so as to raise it
more or less, or by providing ledges at various heights on which to rest the shelf or

page_text: pan. Eeither of these methods involves trouble and inconvenience especially in
dealing with hot material.
This invention relates to simple and convenient means of adjusting the height of a
cooking pan or oven shelf by merely moving a little the oven shelf or the grating or
base plate on which the pan rests, as I shall describe referring to the accompanying
drawing which is a longitudinal section of the appliance according to my invention
for raising and lowering a cooking pan. The pan A rests on a plate or shelf B
which may be a grating or perforated plate. The one end, that is to say the inner
end, of the plate or shelf B is suspended by radius links C, one on each side pivotted
to the sides of the oven or other casing. At the outer end of the plate or shelf Bon
each side of it a stud D projects into a curved slot E formed in the sides of the casing
or of the oven compartment. This slot corresponds in its curvature with the arc in
which the pin of the radius link c moves and it is made with a number of notches e in
any one of which the stud D can be engaged.
When it is desired to raise or lower the pan A. it is only necessary to disengage the
studs D and to pull the plate or shelf B forward or to push it backward and re-engage
each of the studs D in a higher or lower one of the notches e. As every part of the
plate or shelf B is thus moved in a circular arc it is moved always parallel to itself to
a higher or lower level as may be desired, and it is held at that level by the engage-
ment of the studs D in the notches e.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what 1
claim is :-
For raising or lowering a plate carrying a cooking pan or an oven shelf, suspending
one end of the plate or shelf by radius links and engaging studs projecting laterally
at the other end in notches of curved slots, substantially as and for the purpose set
forth.
