FRANK COGHILL c/o Mr. Newton Broughton Road South Shields Marine Engineer
do hereby declare the nature of this invention to be as follows:-
An arrangement below fire bars, and in connection with same, to prevent them from
being pricked up into the fires, thereby causing fire bars to be burned away &
wasted, by this arrangement I stop this waste of fire bars.
1st. The bars are cast with lug on one end to take catch running across the whole
of bars (underneath).
2d. Which is worked by handle in connection with catch to frunt of furnace.
3d. Made so that bars can be locked and unlocked as required, by working handle
in connection with catch that holds down bars.
4th. This catch is supported by means of plates bolted on ordinary bar bearer
brackets, at each side of furnace.
Dated this 24th day of September 1887.

Engineer do hereby declare the nature of this invention and in what manner
the same is to be performed, to he particularly described and ascertained in and
by the following statement:-
It is an arrangement below fire bars, and in connection with same to prevent
pricking bars into fires & burning away.
(1st) The bars are cast with lug on one end, to take catch running across whole
of bars (underneath), this catch made to fit on top of lug, cast on bars for the
purpose, (when bars are locked).
(2nd) The catch is carried by plates bolted on ordinary fire bar bearer brackets,
at each side of furnace, the catch working in those plates by small journals at each
end for the purpose of locking and unlocking bars as required.
(3rd) The working of catch is effected by moving a rod handle at front of furnace
attached to arm on catch for working same, this arm is on one side of catch only.
There are is a catch for each set of bars (back & front bars) wrought by separate rod
handles at each side of furnace, attached to arms of catches (one arm for each catch), so
that you can work back bars catch from one side of furnace front, and front bars
catch from the other side of furnace front.
(4th) The rod handle in connection with arm of catch, is carried by brackets bolted
on front of furnace.
(5th) When bars are locked in position, the catch is kept in place by a pin put
through rod handle at front of furnace, thereby preventing rod handle from moving,
thus securing catch firmly in place; this pin is made to remove for locking and
unlocking purposes as required.
(Gth) The lug that is cast on bars is rounded on top surface, that takes catch, and
the catch is made to fit this exactly, bearing on full surface of lug, by this it prevents
bars from lifting at either ends, thereby locking bars firmly in position.
The form of fire bars is the same as ordinary fire bars, as shown on drawing,
with the only addition of a lug cast on one end, for the reception of catch, and by this
means the bars are kept firmly in position, preventing bars from lifting into fires
through pricking, and then burning away and wasting.
In the drawings C are the catches, I the lugs, P the plates for carrying the catches
and R the rods for working the catches all arranged in working position and as above
described.

*
It is an arrangement below fire bars, and in connection with same to prevent
pricking bars into fires & burning away.
(1st) The bars are cast with lug on ono end, to take catch running across whole
of bars (underneath), this catch is made to fit on top of lug, cast on bars for the
purpose, (when bars are locked).
(2nd) The catch is carried by plates bolted on ordinary fire bar bearer brackets,
at each side of furnace, the catch working in those plates by small journals at each
end for the purpose of locking and unlocking bars as required.
(3rd) The working of catch is effected by moveing a rod handle at front of furnace
attached to arm on catch for working same, this arm is on one side of catch only.
There are a catch for each set of bars (back & front bars) wrought by separate rod
handles at each side of furnace, attached to arms of catches (one arm for each catch), so
that you can work back bars catch from one side of furnace front, and front bars
catcli from the other side of furnace front.
(4th) The rod handle in connection with arm of catch, is carried by brackets bolted
on frunt of furnace.
(5th) When bars are locked in position, the catch is kept in place by a pin put
through rod handle at frunt of furnace, therefore preventing rod handle from moveing,
thus secureing catch firmly in place this pin made to remove for locking and unlocking
purposes as required.
(6th) The lug that is cast on bars is rounded on top surface, that takes catch, and
the catch is made to fit this exactly, bearing on full surface of lug, by this it prevents
bars from lifting at either ends, thereby locking bars firmly in position.
The form of fire bars is the same as ordinary firo bars, as shown on drawing,
with the only addition of a lug cast on one end, for the reception of catch, and by this
means the bars are kept firmly in position, preventing bars from lifting into fires
through pricking, and then burning away and wasting.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what 1
claim is
CHI IS:
1st. A saving of fire bars.
2nd. slight saving in fuel.
3rd. A better command of steam.
