Tin, Lead, or other Metals or Alloys.
We, HENRY FRANCIS TAYLOR and WILLIAM PEDDIE STRUVÉ both of the firm
of Taylor, Struvé, Eaton and Price of Neath and Briton Ferry in the County of
Glamorgan Engineers do hereby declare the nature of this invention to be as
follows:-
In the Specification of Taylor and Leyshon's Patent No. 2106 of 1882 were described
a method of and apparatus for coating and finishing plates in one operation and by
one apparatus or pot in which are used a cradle and nipping appliance for pulling
down the plate to be coated which is then canted and raised into the nip of the rolls
on the exit side of the pot. Now according to this our invention we provide as an
addition to such apparatus or in connection with apparatus operating in such or
similar manner certain mechanical appliances for canting the parts supporting the
plate, such appliances being operated self actingly and consisting of a tooth rack,
quick pitched screw or equivalent part impelled in one direction from a revolving
shaft such as the one imparting motion to the rolls of the apparatus, means being
provided for throwing the impelling part out of gear at the proper moment, so that
the parts may return freely into the original position ready for a fresh operation.
In one form or construction we connect the guide rod or rods for the cradle (such
guide rods being generally termed "the gate with the guided end of a tooth rack
rod by means of a connecting rod. The other end of the rack rod is supported by a
roller or bowl on a lever or rod.
When the cradle and plate are taken down to the necessary depth at the entrance
side of the pot the latter part of this stroke brings a tappet on the cradle handle
against one end of the lever the other end of which carries the roller or bowl which
in rising lifts the outer end of the rack into gear with the impelling pinion.
The rack rod is thereby moved over towards the exit side and when the rack has
been brought properly over the pinion has come to the end of the teeth in the rack
and mounts upon an untoothed part of the rack thereby throwing the rack out of gear

page_text: depressing the bowl end of the rack rod and the bowl and its lever and by the tappet
connection imparting a slight lifting movement to the cradle handle and thereby
advising the workman who holds the handle that the plate is in the right position for
being raised into the nip of the rolls so that he may now continue the upward move-
ment to bring the plate into the nip of the rolls. As the rack was brought out of
gear with the pinion the gate can now by means of a weight or spring be brought
back into the former position at the entrance side of the pot so that the cradle is
ready to receive a fresh plate. The workman having lowered the cradle the rack will
come into gear with the pinion and the action repeated. The tooth part of the
rack rod may be fixed to the top of a rod made of channel iron in which the
bowl rolls.

1, HENRY FRANCIS TAYLOR and WILLIAM PEDDIE STRUVÉ both of the firm of
Taylor, Struvé, Eaton and Price of Neath and Briton Ferry in the County of
Glamorgan Engineers 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 the Specification of Taylor and Leyshon's Patent No. 2106 of 1882 were described
a method of and apparatus for coating and finishing plates in one operation and by one
apparatus or pot in which are used a cradle and nipping appliance for pulling down
the plate to be coated which is then canted and raised into the nip of the rolls on the
exit side of the pot.
Now according to this our invention we provide as an addition to such apparatus
or in connection with apparatus operating in such or similar manner certain mechanical
appliances for canting the parts supporting the plate, such appliances being operated
self actingly and consisting of a tooth rack quick pitched screw or equivalent part
impelled in one direction from a revolving shaft such for instance as the one which
imparts motion to the rolls of the apparatus, means being provided for throwing the
impelling part out of gear at the proper moment, so that the parts may return freely
into the original position ready for a fresh operation.
In the accompanying drawings we have shewn one form or construction Figure 1
being a vertical longitudinal section Figure 2 a vertical transverse section Figure 3
front elevation and Figure 4 a plan.
A is the guide rod (or rods) generally termed the gate which we by means of a
connecting rod B connect with the guided end of a tooth rack C, the said end being
as an example jointed to a block B₁ working between flat guide bars B². The other
end of the rack rod C is supported by a roller or bowl D provided in one end of
a double armed lever D working on a fulcrum pin D³. The upper part of the
cradle operating handle E has a tappet E' which when the cradle and plate are
taken down to the necessary depth at the entrance side of the pot and during the
latter part of such down stroke comes against and depresses one end of the lever D
thus raising the other end which carries the roller or bowl D₁ and lifting the outer
end of the rack Cinto gear with the rack impelling pinion F. The rack rod C is
thereby moved over towards the exit side, and when the rack has been brought
properly over to that side the pinion F has come to the end of the teeth in the
rack C and mounts upon the untoothed part C', shewn, of the rack, thereby throwing
the rack out of gear depressing the bowl end of the rack rod C and the bowl D' and
ts lever D and raising the other end of the said lever so that the tappet connection E'
mparts a slight lifting movement to the cradle handle E and thereby advising the
workman who holds that handle that the plate is in the right position for being

page_text: raised into the nip of the rolls so that he may now continue the upward move-
ment of the handle and cradle to bring the plate into the nip of the rolls. As the
rack was brought out of gear with the pinion F the gate A can now by means
of a weight C or spring be brought back into the foriner position at the entrance
side of the pot so that the cradle is ready to receive a fresh plate. The workman
having lowered the cradle the rack C will come into gear with the pinion F and the
action repeated. The tooth part of the rack rod C may be fixed to the top of a rod
made of channel iron in which the bowl D' rolls as shewn in Figure 3. The rack
rod is by preference made with a fork end for easy detaching by merely lifting it
off the pins A' on the gale A. If instead of the tooth rack we employ a quick
pitched screw we cause the same to be continuously rotated and gear it with a
half nut which is connected to the gate lever and is automatically put in and out
of gear the latter being effected by the nut rising upon an unthreaded part of the
screw spindle.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed we declare that what we
claim is -
First The improvements in the construction of the cradle and nipping appliance
described in the Patent Specification 2106 of 1882 (in which the plate is taken down
and canted and again lifted by the workman) and of other appliances operating in a
similar manner, whereby the cradle is canted mechanically instead of by hand and the
cradle handle then raised slightly mechanically to advise the workman that the plate
is in the right position for being raised by him into the nip of the rolls the cradle
being brought back by a weight or spring substantially as set forth.
Second: In a cradle canting appliance the application and use of a tooth rack C
with untoothed part ₁ (or a screw with unscrowed part) for throwing the rack out
of gear with its impelling pinion (or the half nut out of gear with the screw) for
the purpose of enabling the cradle to be brought back into its starting position on
the entering side of the pot substantially as set forth.
Third: The construction of cradle canting and lifting appliance shewn on the
drawing.
