Year: 1879

page_text: LETTERS PATENT to Edwin West Killick, of Northfleet, in the County of
Kent; for the Invention of “ IMPROVEMENTS IN LIME AND CEMENT KILNS,
AND IN DRYING FLOORS."
Sealed the 4th April 1879, and dated the 30th January 1879.
PROVISIONAL SPECIFICATION left by the said Edwin West Killick at the
Office of the Commissioners of Patents on the 30th January 1879.
EDWIN WEST KILLICK, of Northfleet, in the County of Kent.
MENTS IN LIME AND CEMENT KILNS AND IN DRYING FLOORS."
"IMPROVE-
The improvements consist in constructing such kilns with vertical in lieu of
benched sides in combination with drawing eyes or apertures arranged in pairs or
other convenient number on each side of the kiln in lieu of a single eye at each side
as at present; also in constructing one kiln, or a series thereof; in combination with
arched bays for supporting and carrying a continuous upper drying floor which
shall allow of men and waggons to pass under and work an under floor, thereby
doing away with lateral or cross walls between the floors as at present; and forming
a continuous covered way or flue by means of said upper and lower, drying floors.
Also in furnishing said flue with one or more small and subsidiary furnaces in or
near the end of the flue for the purpose of burning and consuming the unconsumed
gases and smoke from the kiln or kilns. And, lastly, in combination with the above
improvements, or any of them, in the use of one or more tramways and waggons for
carrying and supplying coke or fuel and the various materials to be burnt and
dried. The various parts are constructed of materials suitable for the purpose as at
present, and their arrangement and disposition, save as otherwise mentioned above,
are intended to be as at present and will vary more or less, as in all kilns, according
to the nature and section of the ground.

" IMPROVE-
Also
The improvements consist in constructing such kilns with vertical in lieu of
benched sides, and with drawing eyes or apertures arranged in pairs or other con-
venient number on each side of the kiln instead of a single eye at each side as at
present so as to enable a greater number of men (for instance 4) to draw at the
same time.
Also in constructing a. kiln, or a series thereof, in combination with
arched bays for supporting a continuous upper drying floor which shall allow of
men and trucks passing under the same and working on the lower floor, thereby
avoiding the application of cross walls, and forming a continuous covered way or
flue between the said upper and lower drying floors. Also in providing the flues
with dampers in such a manner that the gases and smoke from any of the kilns can
be made to pass over another kiln or other kilns before they enter into the drying
chamber or chambers in order to complete their combustion and to consume, the
smoke; also in using an auxiliary furnace; which may be placed in the flue near the
chimney for the purpose of consuming any smoke that may escape unburnt.
in loading the kilns with coke and cement at the same time, and by means of rail-
roads constructed on or over the floors, those parts of the railroad which carry and
pass over the kilns being made movable so as to be easily fixed or removed. I
prefer to use wagons or trucks with movable bottoms, which discharge exactly the
required quantity of coke into the kiln through an opening formed in the upper
floor by removing a plate or otherwise, thereby securing a more uniform burning of
the cement; said trucks may be filled at the base of the kiln and then hoisted to
the level of the railroad. The upper drying floor is most advantageously formed
by metal plates placed at such a distance from the lower floor that men can
work on the latter without removing any plates. The kilns are preferably
placed in rows and worked continuously, being charged while they are burning,
and the gases can be made to pass over the kilns either longitudinally or trans-
versely. The movable rails which are laid across the kilns can be fixed in slots
and held down by clamps or otherwise while they carry the trucks. The
accompanying Drawings, Sheet I. and II., show two examples of the improved
kilns and drying arrangement, Fig. 1 being a longitudinal section, Fig. 2 á horizontal
section, and Fig. 3 a cross section of a duplex arrangement (two rows of kilns with
their drying floors); Fig. 4, a longitudinal section, and Fig. 5, a sectional plan of a
single row arrangement on a larger scale; Fig. 6, a horizontal section of two kilns
above the grates; and Fig. 7, a vertical section between two kilns of a row.
A,
and A',
1.2 8 4 5 6
1 2 3 4 5 6 are the kilus, each provided with two pairs of draw
eyes a, b, c, d.; B, B1, B2, are the lower, and C, C1, C2, the upper drying floors, the
latter being supported by arches c¹, c², c³; D, D¹, are the external flues communi-
cating with the drying chambers through openings d¹, d², provided with dampers;
E, E, are the chimneys, and F, F', the auxiliary furnaces, G, G¹, are rails, and H, H',
the trucks for charging the kilns with cement and coke; I, I, are openings in the
walls between the lower or drying chambers, provided with dampers for establishing
or interrupting the communication between adjacent ki!ns; Fig. 2 shows in the
centre a plan of the upper drying floor, and on the sides a horizontal section through
the flues or lower drying chambers; one half of Fig. 3 is a vertical section through

page_text: a row of kilns, and the other half a section through drying chambers. The hearth
is divided into parts by a dwarf wall, and the upper floor of the duplex arrangement
covered by an iron roof.
In witness whereof, I, the said Edwin West Killick, have hereunto set my
ha-n-D and seal, this Twenty eighth day of July, A.D. 1879.
