Improvements in Appliances connected with Charging and
Discharging Coke and like Ovens.
I, THOMAS GRAHAM LITTLEBOY, of Brymbo, in the County of Denbigh, Electrical
Engineer, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide appliances which will enable the
charging of coke and like ovens with raw material to be economically effected with
a minimum of labour and by means of which the doors at the ends of the ovens
can be opened for discharging and closed with ease and rapidity without exposing
the attendants to the fumes from the ovens. The invention is specially
applicable to coke or other ovens composed of a series of long narrow chambers.
For these purposes I make use of a framework or carriage provided with wheels
and free to be moved to and fro on rails along the top of the ovens. Any
convenient means or gearing, either hand or power, may be used for giving
motion to the framework or carriage. The said framework or carriage is
provided with hooks, buffers, or other connections by means of which the usual
charging trucks may be moved along the top of the ovens to the various
charging holes, and I prefer that the framework or carriage should travel on the
rails which carry the trucks. The said framework or carriage is also provided
with a winch having chains or ropes passing over pulleys on jibs attached to the
framework or carriage the said chains or ropes being provided with connections
for attachment to the doors at the ends of each oven so that such doors can be
raised to allow of the contents of the oven being discharged and lowered again
when the oven is to be recharged. Motion is imparted to the raising and
lowering appliances by hand or power as convenient. Any suitable hoisting
appliances other than a winch and chains may be used if desired.

DESCRIPTION OF THE DRAWINGS.
Figs. 1 and 1 on Sheets I and II are a side elevation. Figs. 2 and 2
on Sheets III and IV are a plan and Fig. 3 on Sheet V is an end view of
appliances constructed under my invention. 1 is à carriage or framework
mounted on wheels 2 so that such carriage is free to be moved along the tops
of the ovens 3 on rails 4. 5 is worm, bevel, and spur gearing on the carriage
by means of which traversing motion in either direction may be communicated
to the carriage in any usual way. 6 are clutches for throwing the gear into and
but of action. 7 is a grooved pulley on a shaft 8 carried in bearings on the
carriage for operating the gear 5. The pulley 7 receives motion from a flying
rope in any usual way. 9 are hooks and buffers by which the usual trucks 9"
for charging coal into the ovens can be drawn along the rails till they are
over the desired charging holes. It will be noticed that the wheels of the
carriage run on some of the same rails on which the trucks run. 10 are jibs
or cranes at each end of the carriage provided with pulleys 10" over which
pass chains or ropes 11 from a winch 11 on the carriage. Any suitable over-
hanging structures or framework may be employed instead of jibs. The chains
or ropes are provided with hooks or other connections 12, by means of which
the doors 13 of the ovens can be raised out of way of the discharging appliances.
The winch 11 may be operated by hand gear 14 or from the shaft 8 by the
clutch and gearing 15, or in any other convenient way.
The operation is as follows: The carriage 1 draws loaded trucks 9 along the
rails 4 towards the oven to be charged, the hooks 12 are attached to the doors 13,
the doors are unfastened, and the winch 11 is then operated so as to raise
such doors away so that the coke may be discharged from the oven the doors
are then lowered and fastened, the carriage is again moved so as to bring the
trucks over the charging holes and the oven is recharged. The carriage then
pushes the trucks back again to be reloaded, and the same operations take place
for recharging another oven.
I do not confine myself to the particular arrangement of gearing for trans-
mitting power or to the construction of parts described as many modifications may
be made without departing from my invention, as for instance, shafting,
electricity, hand power, or a steam engine on the carriage, may be used instead

page_text: of a rope for giving motion to the carriage or hoisting appliances in any well
known way also the hoisting appliances may consist of levers or other devices
instead of a winch and chains.
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:
-
First. The combination with coke or like ovens of a travelling carriage pro-
vided with hoisting appliances for raising and lowering the doors of the ovens,
and with hooks, buffers, or other connections for moving the charging trucks,
substantially as set forth.
Second. The combination with a travelling carriage of hoisting appliances,
and connections for moving trucks, substantially as and for the purposes set
forth.
