I, BRIERLEY DENHAM HEALEY of Bamber Bridge in the county of Lancaster
Civil Engineer do hereby declare the nature of my invention for IMPROVEMENTS IN
AND CONNECTED WITH FURNACE ROCKING BARS to be as follows :-
This invention relates to fire grates in which rocking bars are used for breaking up
the clinker and is an improvement on the system of bars shewn and described in the
specification of a patent which was granted unto me A.D. 1886. No. 9342.
According to the present Invention instead of all the firebars moving in one
direction when agitated, one half moves in an opposite direction to the other half, all
the odd number bars 1, 3, 5 &c. being attached to one end, and all the even number
bars 2, 4, 6 &c. to other end of a T-shaped rocker by means of two connecting
links.
The centre limb of said rocker has a socket into which a movable lever is inserted
when the firebars are to be agitated. The said rocker is attached to the deadplate by
a pin at the centre of its upper limb, and each end of said rocker is coupled to the
said connecting links by means of short adjusting rods.
One half of the rocking bars has a snug a few inches to the right of centre tooth
and the remaining half has a snug a few inches to the left of centre tooth, in each of
which snugs is cast a wrought iron pin for attaching the connecting links to.
The grate may be erected at any angle up to say 45° and the firebars will remain in
the required working position, without the use of any stop or catch gear as one half
the bars exactly balances the other half.
Dated this First day of September 1887.

Applicant.

Civil Engineer 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 fire-grates in which rocking bars are used for breaking up
the clinker and is an improvement on the system of bars shewn and described in the
specification of a patent which was granted unto me A.D. 1886. No. 9,342.
According to the present Invention instead of all the fire bars moving in one
direction when agitated, one half moves in an opposite direction to the other half, all
the odd number bars 1, 3, 5 being attached to one end, and all the even number
bars 2, 4, 6, to other end of a T-shaped rocker 7 by means of two connecting
links, 8 and 8".
The centre limb of said rocker has a socket 10 into which a movable lever is inserted
when the firebars are to be agitated. The said rocker is attached to the dead plate
by a pin at the centre of its upper limb, and each end of said rocker is coupled to the
said connecting links by means of short adjusting rods 11 and 11*.
One half of the rocking bars has a snug 12 a few inches to the right of centre tooth
and the remaining half has a snug a few inches to the left of centre tooth, in each of
which snugs is cast a wrought iron pin 13 for attaching the connecting links to.
The grate may be erected at any angle up to say 45° and the firebars will remain in
the required working position, without the use of any stop or catch gear as one half
the bars exactly balances the other half.
And in order that this invention may be better understood I will now explain it with
reference to the accompanying sheet of drawings.
Figure 1 is a plan shewing part of a firegrate Figure 2 is a section of the same,
and figure 3 is an enlarged section of four of the firebars as they appear when tilted to
break up the clinkers. A greater or less number of bars may be used to suit the
size of the firegrate and the nature of the fuel to be used.
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
1. Constructing and using rocking bars for furnace firegrates, substantially as
herein shewn and described.
2. The combination with such rocking bars of a rocking arm and adjusting rods
the operation of which causes one half of the bars to oscillate in an opposite direction
to the other half.
