Year: 1885

page_text: We GEORGE KINNAIRD, senior, GEORGE KINNAIRD junior and JOHN KINNAIRD
(Sons of the first named George Kinnaird) Ironfounders & Manufacturers, trading
under the style of "Kinnaird & Ferguson" at Queen's Park Foundry Cavendish
Street, Glasgow, in the County of Lanark do hereby declare the nature of our
invention for IMPROVEMENTS IN COOKING RANGES to be as follows:-
It consists of a novel and original mode of suspending a solid "Girdle," or
railed "Gridiron," over the open fire of such ranges for purposes of Cooking,
and is only applicable to those Ranges which have an open fire, or Combined
open & Close fire, arrangement.
This plan consists in fitting a Pivot or Pivots with rounded or other shaped end
or ends into holes of corresponding form or forms in the hob or hot plate of the
range, and attached, either permanently or otherwise to the margin of the Girdle
or Gridiron, for the purpose first above described.
The Pivot, or Pivots, fitted to, or into, the Hob, Hot plate or reducing cheek
of Open fire Ranges for the purpose of suspending the Girdle or Gridiron over the
fire is the essential principle of our Invention.

page_text: We, GEORGE KINNAIRD senior and GEORGE KINNAIRD junior, and JOHN
KINNAIRD (sons of the first named George Kinnaird) Ironfounders and Manu-
facturers, trading under the style of Kinnaird and Ferguson at Queen's Park
Foundry No 43 Cavendish Street Glasgow in the County of Lanark, do hereby
declare the nature of our invention for IMPROVEMENTS IN COOKING RANGES and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
It consists in a particular method of attaching a Girdle or Gridiron to, or sus-
pending the same over the open fire of, an open or Combined open and Close Fire
Range for cooking or other purposes by means of a Pivot fitted to, or into a hole
within, the Hob or other margin of the fire; and in the particular construction of
the Girdle or Gridiron to be so used.
First the Plan just briefly summarised is effected by fitting a Pivot with rounded
or other shaped end or ends, into a hole, or holes, of corresponding form in the Hob
or Hot plate of the range and attaching the pivot, either permanently or other-
wise to the margin of the Girdle or Gridiron. The purpose being to enable the
cooking or other utensil to be easily withdrawn from the fire without the labour
or inconvenience of lifting it, the pivot serving as an axis or centre upon which
the apparatus, may be swung round after the manner of a swing trivet. The Pivot
may be loose and not attached to either the cooking utensil or the range or it may
be attached to either of them. If it is loose and capable of removal from the utensil
and from the range, one of its ends must be rounded and fitted into a circular hole
to enable the Girdle or Gridiron to be moved round into any position required.
Either the upper or lower end of the pivot may have the rounded end or pin and
the other end may be square, trangular, round, oval, oblong or irregular in shape as
required.
The lower part of the pivot is made to fit within a socket or hole of corre-
sponding shape in the Hob or Hot plate of the range and near the margin of the
fire and the upper part of it is made to fit within a hole or socket similarly shaped
to that end, in or upon the margin of the Girdle or Gridiron, and when the lower
part of the pivot is fixed into its socket and the Girdle or Gridiron placed upon the
upper part of it, the apparatus has a very similar appearance to a swing trivet and
may be turned into a position over the fire for cooking-or removed with ease
either by swinging it upon its own axis or the upper part may be lifted from the
pivot and taken away.
と
As an altenative mode of applying this pivot arrangement to open fire ranges
which have a contracting or reducing cheek the pivot may be fitted into a socket
made in or attached to the said moveable or contracting cheek.
A further alternative method is to attach a pin or pivot to the under side of the
Girdle or Gridiron or on one of the outer edges of them, and fit it into a hole or
socket of corresponding shape in the hob, moveable cheek or upper part of the pivot
which in the foregoing description has been represented. as separate from, and not
attached to, the Girdle or Gridiron. The Pivot may also be united permanently
to the Girdle or Gridiron, either by casting it with or otherwise attaching it to
the same.
Pivots may also be attached to both upper and lower surfaces of the Girdle or
Gridiron, or to suitable members thereon and connected with a bracket attachment
upon the adiacent part or parts of the range.

page_text: The outline or shape of the Girdle or Gridiron may be either circular, oval,
oblong, square, triangular or irregular, and the substance or substances of which
they are composed may be wholly or in part Cast or Wrought Iron, Steel or
other metal.
They may also be Enamelled, Galvanized or plated.
In so far as the substances composing the Girdle are not wholly metal of some
kind the other material employed is Stone or Baked clay such as Fire brick, Terra
Cotta or Earthenware and are principally but not exclusively for the baking surface
of the Girdle.
The handle of the Girdle or Gridiron may be fast, moveable or swinging. The
Baking surface of the Girdle may be embossed or plain.
The several accompanying diagrams will further illustrate the principle and
details of this invention.
Fig. 1 shews a detached Pivot with rounded ends and its proximity to its socket
or hole in the margin of the fire.
Fig. 2 shows a detached Pivot with ends of different shapes adjacent to its socket
within the crown of a winding or " contracting cheek."
Fig. 3 shows a detached Pivot with one variety of bracket attachment and pins
of varied forms.
Figs. 4 and 5 shew arrangements of the detached Pivot with holes in upper part
and small pin attachment on under side of Girdle.
Fig. 6 shews Girdle with Pivot attached and with swing handle.
Fig. 7 shews Girdle with long upper end to Pivot-intended for detaching.
Fig. 8 shews Gridiron with Pivot attachment in its position over fire.
Fig. 9 shews Girdle with Pivot attached and upper surface of Girdle composed
of Stone, Brick &c.
Figa. 10 and 11 shew two methods of attaching the Girdle by bracket arrange-
ments and a different form of Pivot.
Fig. 12 shows the application of the Pivot Girdle to an open fire with contracting
cheek.
Figs. 13 and 14 shew the position occupied by the Pivot Girdle in connection
with a combined open and close fire arrangement of cooking range.
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 For the principle of constructing Girdles or Gridirons with Pivot attachments
as described and drawn herein; and for the purposes referred to.
2nd For the principle of connecting such Pivotted Girdles or Gridirons to cooking
and other ranges by means of holes or sockets provided in such ways and of such
a character as shewn herein.
3rd For the principle of constructing Girdles partly of metal and partly of stone
or baked clay, after, or similar to, the manner of (and for such and similar purposes,
as, and to,) those herein described.
4th For the principle of constructing Girdles with embossed baking surfaces as
herein described.
