Ior Use in Connection with the
Annealing Lier or Lear of a Flint Glass House for Shifting
the Pans from one Level to another.
I, EDWARD MOORE of Tyne Flint Glass Works, South Shields in the county of
Durham, Glass Manufacturer, do hereby declare the nature of said invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :—
My invention applies to "rockers" intended for use in the working of the
annealing lier or lear of a Flint Glass House where the lier or lear is served by a
double row of lear pans, that is, where the empty pans travel back to the fire
underneath the full pans and the full pans travel from the fire over the empty pans.
My invention is shown in the accompanying drawings which represent a
"rocker" at one end of the lier or lear in the two positions it will assume in use.
Two "rockers" A are used for each lier or lear, one "rocker" at the end next
the lear furnace serves the purpose of lifting the empty pan from the bed or line B,
of the empty pans to the bed or line C of the full pans and the second rocker at
the other end of the lier or lear in the sorting room lowers the emptied lear pan
next in turn from the line or bed C of the upper or full pans to the line or bed B
of the empty pans.
The "rockers" A, may be made of either cast or wrought iron, or other metal
aud the radius for describing the arc of the "rocker" may be varied according to
the distance the arms a¹ a¹ of the "rocker" have to travel between the two lines B, C,
of pans or other local conditions.
The "rocker" works on a level bed plate D to which it is attached by pins or
axes d' running through the centre of the side are plates a a of the "rocker" and
working in suitable standards or bearings bolted or otherwise fixed to the bed
plate D.
One end of the "rocker" is furnished with two arms a', a¹, before referred to,
suitable for receiving and carrying the empty pan, the other extreme of the
"rocker" is furnished with a balance weight or weights a² preferably permanently
fixed thereto, the weight of which is about equal to the weight of an empty pan.
Each arm a¹ is provided with a guide stop a³.
The "rocker" A, at the fire end of the lier or lear, is furnished with a handle a
to enable the learman to work it, the handle a' is a bar of iron fixed at or about
n

page_text: the junction of the "rocker" side a and arm a¹ at a right angle thereto and
projecting through the enclosing brickwork and operating in a slot formed in the
enclosing brick work. Contained within the said slot, in the brick work, is a suitable
catch E, with a fork e at each end thereof so that when the handle a' of the
"rocker" A is either depressed, as shown at Figure 2 or raised as shown at Figure 1,
by the learman operating it, to its full extent, one or other of the forks e
automatically slips on to and holds the handle a steadily in its position either up
or down.
At the sorting room end of the lier or lear it is convenient to fix the handle for
moving the "rocker" A, vertically on the end bearing the balance weight, this
handle (not shown) works through the covering wood platform enclosing the top
of the "rocker" and other parts.
The "rocker" A in the sorting room is furnished with a catch, bearing or stop
so arranged that when the "rocker" is either raised or depressed to its due extent,
it may be locked firmly in position by turning the handle of the catch or stop
which is situated conveniently near the handle for working the rocker.
I have not thought it necessary to show the last named catch and parts
connected therewith as such will be readily understood from the above description.
By the aid of my invention I am enabled to raise and lower a lear pan of
specified weight, a specified distance with certainty and ease and under conditions
to which other methods of shifting lear pans are difficult of application, it has also
the merit of extreme simplicity, inexpensiveness and regularity of action.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
A "rocker" for use in connection with the annealing lier or lear of a Flint Glass
House substantially as herein shown and described and for the purpose stated.
