advantage Of this invention consists in the inroddo
ton Of piece Of iron Immediately behind the pin,
which piece 10 pressed forward by slight spiral
sping The pressure of this piece against the end Of
the link is sufficient by the aid OF narrow throat to
maintain the link at any elevation desired, that in
coupling the link may be adjusted TO meet the mouth
of the opposite drsvhead. To make the opposite
draw head secouplng is only necessary to partially
withdraw ihepin, 50 that the spring piece shall pass
under IFS e1trcu ty ard support it. As the come
together the link enters ts mouth presses back the
spring piece allows the pin to drop into place and the
union is completed This invention is highly ap-
proved by all who have examined it. The coupling
of cars, as ordinarily conducted, is a work of
considerable danger to life and limb, particularly in
the night, This invention seems to promise, rather
TO oeeemplh all that is to be desired by avering the
principal sources Of danger, and its obvious con-
venierce and economy of labor seem to insure i. q
rapid introduction 10 general favor.
TEoNPsoSs FURNACE FOR BuRyIsG WAFER
Mr.. Moses Thompson of Binghamton, in this State,
has invented sndput in furnace for burning fine
wet fuel which seems to possess considerable value
Tan, fresh from the watts and dripping with water
becomes in this furnace or system of furnaces very
desirable fuel and ii is claimed for this invention tn At
it ret only buns the carbonaceous in spite of the
aqueous matter but that it actually decemposes aud
burns the water in manner which contributes not
only to the cleanliness and freedom of the fire. but
adds to the actual Of heat derived therefrom. In
short, Mr.. Thompson claims to have in this particu-
lar class of fuel practically solved the great problem
of the economical burning of water. The principle
which depends is the development of an extraor-
binary temperature 1t is theoretically possible to
n oh farm. hv ,hustio
Of any ordinary fuel Precisely how high this tem-
perature may be depends on various circumstances,
which il is needless to discuss the limits are rarely
ifever approached in the furnaces of steam-bolers,
for which use by the way this invention is specially
designed In all such furnaces the close coDtiyuty Of
the comparatively cool surfaces of the boiler abstracts
the heat as rapidly it is generated, and prevents
any accumulation. The furnaces Of Marine and Cor
nh boilers are completely nclosed within the water
the better oreceive all the heat which is radiatedrom
the fire; but for most purposes on land the furnace is
exterior to and in Independent of the boiler,
being usually beneath and inclosed in walls Of brick.
The device for wet fuel may be described az merely
carry ing out TO much greater degree this separation
of the furnace from the water. If the flame and
highly heated gases are finally brought into contact
with and impart their heat 10 the boiler, loss of
effect aocrues from this separation, provided al
why's that the furnsce is so thickly inclosed as
TO preserve its heat and prevent loss by radiation.
On the contrary it possible, in consequence of the
higher temperature, TO effect more comp etc combus-
ton of wood or other ordinary fuel. The furnaces for
wet fuel consist Of two or ovenke receptaces,
almost entirely protected from the reigera.ory effect
of the boiler. In these furnaces which, although lined
with good fire brick, have sometimes yielded to the
intense caoIiGc influence therein developed, the fuel
is exposed op CRATE to the action of very limited
draught of atmospheric air, considerable share Of
the oxygen necessary being supposed to bs obtained
from the decomposition of the water New fuel Is
supplied only TO furnace ct .ne, and the vapor
and smoke from this if not sufficiently heated by
radiation from its walls is sure to be decomposed
by the fame from the other furnace in the mixing
chamber or short passage leading from the furnaces
TO The boiler or boilers The fuel is supplied from the
top and allowed to lay in concal heap on the CRATE,
in which position the combustion commences stimuli
taneousy upon its upper and under surface and soon
extends in streams throughout themass. The furnace
has been employ ed most successfully with tan, and
highly fatteriDg certificates presented of its
adaptabiIity to the burning moro economically OF
begass or fresh crushed sugar-csne. How great
degree Of gain is due to the presence OF moisture in
either or any kind Of fuel has not yet been arrived at
by any close experiment, but all tho results seem to
indicate that this invention viii succeed in rendering
highly valuable many kinds of fuel which until now
have been almost worthless.
