PROVISIONAL SPECIFICATION.
An Improved Construction of Framework for either Rocking or
Stationary Fire Bars of Town's Refuse Destructors, such Frame-
work being Applicable to other Furnaces and to Steam or other
Boilers.
I, HERBERT UTTLEY, of 50 England Street, Leeds, in the County of York,
Refuse Destructor Manager, do hereby declare the nature of this invention to be
as follows:-
This invention relates to an improved construction in a more substantial manner
than has heretofore obtained of the principal framework of the fire-grates of town's
refuse destructors or other furnaces, such framework being adapted for carrying
hand or automatically actuated rocking fire bars or stationary fire bars of the
intersecting or other type, and comprises improved front and back dead plates or
bearers and other bearers for carrying the fire bars proper above referred to.
The abovenamed dead plates as well as the other bearers and also the fire bars
are preferably of cast iron.
The back dead plate or bearer has in addition to a strengthening rib and in
connection therewith pockets formed thereon for the reception of one or more
central or intermediate bearer or bearers when more than one series of fire-bars are
required to form a grate (according to its size,) similar pockets being also provided
on the said back dead-plate for receiving the outside bearers complementary to the
aforesaid central or intermediate bearer or bearers.
These central or intermediate bearers as well as the outside bearers are secured
in their respective pockets in the back dead plate by headed pins passing trans-
versely through the said pockets and bearers, the heads of such pins being sunk
flush into the top side of the said back dead plate. The other ends of the above-
named bearers are provided with feet that bear upon and are bolted to a suitable
projection of the front dead-plate, thus completing the improved framework ready
for the reception of the fire-bars.
The fire bars have lateral projections on each side, the projections on one bar
intersect with the projections of the next bar. This feature in fire-bars however is
not new. The bars may be actuated either by hand or power.
Dated this 17th day of October 1890.

COMPLETE SPECIFICATION.
An Improved Construction of Framework for either Rocking or
Stationary Fire Bars of Town's Refuse Destructors, such Frame-
work being Applicable to other Furnaces and to Steam or other
Boilers.
I HERBERT UTTLEY of 50 England Street Leeds in the County of York Refuse
Destructor Manager 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 :—
Fig. 1. is a front view of the refuse destructor fire front, with double doors E.
made of cast iron.
Fig. 2
a plan of the front bed plate F, and fire bars G. and the two side
bearers H and centre bearer I and the top back dead plate A with teeth in. The
aforesaid top back dead plate has three pockets cast on, under the said dead plate,
so as to admit the tennons ends O. of the right and left hand and centre bearer H. I.
to their proper places in the said back dead plate A.

page_text: Fig. 3 is a side view of the cast iron fire front also front bed plate F and fire bars G.
the two side and centre bearers H. I. and the two wrought iron connecting rods K, for
agitating the said fire bars G, also the bell crank L, and bracket M, which are
secured underneath the front bed plate by two sett screws R.
Fig. 4 is a plan only one half being shown shewing the right and left hand side
bearer H, and the centre bearer I. The ends of the said bearers are provided with
feet N, that bear upon and are bolted to a suitable projection B, cast on the inside
of the said dead plate F.
The tennons ends O, of the said bearers and the centre bearer H. I. are secured
in their respective pockets in the back dead plate A, by headed pins P, passing
transversely through the said pockets and bearers, the heads of such pins are sunk
flush into the topside of the said back dead plate A, thus completing the improved
framework ready for the reception of the fire bars G.
C on Figs. 1 & 3 is a loose iron or steel strip which is attachable to the front,
dead plate F, by sett screws Q, and can be replaced when worn out.
D on Figs. 2 & 3 is a cast iron fixture bar having projections cast upon it to enter
into the openings which are cast in the first rocking bar G, this said fixture front
bar rests upon a lip B, cast upon the front bed plate F, with suitable slotholes cast
in the said lip. This front fixture bar D, is secured on the front of the bed plate F,
with bolts passing transversely through this front fixture bar D, and the feet of the
bearers N, and the lip B cast on the bed plate F, with flush headed bolts.
The rocking fire bars are of the usual intersecting type, and are actuated hori-
zontally by inserting a wrought iron lever in the bell crank L. When the said
lever is moved to the right and left, the connecting rods K move forwards and
backwards, one half of the fire bars moving upwards, the other half moving down-
wards, thus preventing the clinkers adhering to the fire bars G.-but any system of
rocking bars may be used.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
A. The construction of the top back dead plate A, in the furnace, which is
provided with suitable teeth in the said back dead plate for the companion working
bars. The said top back dead plate has three pockets cast on underneath the
aforesaid dead plate. In addition to a strengthening rib cast on underneath the
whole length of the said dead plate, the tennons ends of the said right and left hand
and centre bearers are inserted in these pockets cast on the dead plate underneath,
and are secured by bolts passing transversely through the top back dead plate and
the tennons ends, thus securing the framework in its proper position.
B. The provision of a lip B, cast on the inside face of the front bed plate for the
right and left hand and centre bearers to rest on. These bearers have suitable feet
cast on to rest on the aforesaid lip with slotholes cast in to allow for contraction
and expansion.
C. A renewable cast iron or steel strip C, fixed in the recess of the front bedplate
secured by two sett screws, so as to be replaced when worn out by the action of
the fire irons and ashes, thus preventing a rush of cold air passing over the fires at
this point.
D. The cast iron fixture front bar D, having projections cast upon it to enter
into the openings of the companion bars. This said fixture front bar rests upon the
lip cast upon the inside face of the front bed plate also upon the right and left hand
and centre bearers feet, which have slotholes cast in to allow for contraction and
expansion and are secured by bolts passing transversely through the fixture front
bar and the feet of the three bearers and lip which is cast upon the inside front
bed plate thus completing the framework for the reception of the fire bars.
