PROVISIONAL SPECIFICATION.
Improvements in Linings and Shelf Carriers for Gas Ovens.
We, WILLIAM RUSSELL of the Scotia Foundry, Pendleton in the County of
Lancaster, Ironfounder, ALFRED CLARE of Thynne Street Warrington in the
County of Lancaster, Director, and FLETCHER RUSSELL & CO. LIMITED also of
Thynne Street, Warrington in the County of Lancaster, Manufacturers of Gas
Apparatus, do hereby declare the nature of this invention to be as follows:-
This invention relates to shelf carriers and linings for gas ovens, and its object is
to enable the carriers and linings to be removed and replaced or substituted with
facility and convenience.
According to our invention we construct the shelf carriers or linings with one or
more lugs or projections upon one or both side edges, the lugs of one edge being
capable of engaging behind a flange or with a groove formed in either the vertical
door frame or the back frame of the oven. Upon the lining or shelf carrier we
may cast a hook and form a corresponding catch or staple upon the inside of the
oven casing. Alternatively the positions of the hook and of the staple or catch
may be reversed, or, if the lining or shelf.carrier is provided with lugs or projections
upon two edges, the second series of lugs may engage with hooks or similar
devices.
To remove the lining or shelf carrier it is only necessary to lift it far enough to
disengage the hook or similar device or devices, when it may be moved laterally
to free the lugs from the groove or flange and be removed bodily from the oven.
To replace it, the lugs are inserted behind the flange or within the groove, and the
lining or shelf carrier after being moved laterally against the side of the oven, is
dropped so as to bring the hook and staple or similar device into engagement.

Improvements in Linings and Shelf Carriers for Gas Ovens.
We, WILLIAM RUSSELL of Scotia Foundry, Pendleton in the County of
Lancaster, Ironfounder, ALFRED CLARE of Thynne Street Warrington in the
County of Lancaster, Director, and FLETCHER RUSSELL & Co. LIMITED also of
Thynne Street, Warrington, Manufacturers of Gas Apparatus, 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 relates to shelf carriers and linings for gas ovens, and its object is
to enable the carriers and linings to be removed and replaced or substituted with
facility and convenience.
According to our invention we construct the shelf carriers or linings with one or
more lngs or projections upon one or both side edges, the lugs of one edge being
capable of engaging behind a flange or with a groove formed in either the vertical
door frame or the back frame of the oven. The lining or shelf carrier is provided

page_text: with a hook or the like and a corresponding catch or staple is formed upon the
inside of the oven casing. Alternatively the positions of the hook and of the
staple or catch may be reversed, or, if the lining or shelf carrier be provided
with lugs or projections upon both edges, the second series may engage with hooks
or similar devices.
For the purpose of illustrating how our invention may be carried into effect
we have hereto appended a sheet of drawings to which we make reference
hereinafter.
Figure 1 illustrates in elevation a skeleton shelf carrier embodying these
improvements.
Figure 2 represents the same carrier in edge elevation.
Figure 3 shews a horizontal section of an oven with two of the improved shelf
carriers in place.
It will of course be understood that although our improvements are only shewn
as applied to a skeleton shelf carrier they are equally and obviously applicable to
solid shelf carriers or lining plates.
The shelf carrier consists of a plate or frame A provided with slides or brackets B
upon which the shelves are supported. Upon one or both side edges of the plate A
are formed extensions or lugs CC and DD. Formed upon or secured to the back
of the plate is or are the hook or books E E. It is preferred to form the plate
with the projections or lugs upon both side edges and with two hooks so that the
same plate may be used equally well upon either side of the oven.
To place the plate in position in the oven the lugs upon one of its edges are
engaged with a groove or behind a flange F formed vertically in the door frame, or
on the side of the oven. See Figure 3. The plate is then moved laterally against
the side of the oven and is dropped so as to bring one of the hooks E into engage-
ment with the staple or catch G formed on the interior of the oven casing. Te
remove the lining or shelf carrier it is only necessary to lift it far enough to
disengage the hook, when it may be moved laterally to free the lugs from the
groove or flange and be removed bodily from the oven.
If
Instead of forming the groove or flange at the front of the oven it may be formed
at the back in which case the staple G would be nearer the front of the oven.
desired, in cases where lugs or projections are formed upon both edges of the plate,
the staple G may be dispensed with and the lugs upon the free end of the plate
may engage latches, hooks, or the like attached to the oven side. The back of the
oven may be similarly provided with a plate H which may be similarly secured in
place or which may be held by the two side plates when the latter are in position.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
A shelf carrier or lining for a gas oven, constructed and arranged substantially as
and for the purpose herein before described and as illustrated by the accompanying
drawings.
