centre, between those wheels; and 
therefore, in the above description, I 
have endeavoured to shew how effec- 
tually this may be done by my afore- 
said invention. But, in some cases, it 
may be necessary to bring the pressure 
of the load as low down as possible, 
and to equalize it between the two sides 
of the carriage, so as to cause one to 
balance the other. This is particularly 
the case in the attempts which have 
been made to construct vehicles with 
one wheel only, in which there is no- 
thing to maintain the erect position of 
the vehicle, but the attachment of the 
shafts to the horse’s body, and preserv- 
ing as correct an equilibrium as_possi- 
ble on either side of the wheel. My 
invention of cross levers is particularly 
applicable to this purpose.’”’—London

To Mr. JouN REEDHEAD, of Hey- 
worth, Durham, and WM. PARRY, 
of East Lane, Walworth, Surrey, 
for certain Improvements in Propell- 
ing Vessels. 
These improvements consist of two 
parts, first in the employment of several 
pairs of paddle-wheels for the purpose 
of propelling ships, boats, barges, &c. ; 
and secondly, in a mode of enclosivg 
or shutting up the said paddle-wheels 
in tempestuous weather; by which the 
ship, boat, or barge may be converted 
into an ordinary vessel to be then pro- 
pelled by canvas sails to be acted upon 
by the wind. 
The wheels are made to revolve by 
means of a steam-engine or other first 
mover: by the paddles dipping into 
the stream which flows freely through 
the channel, the resistance of the water 
propels the vessel forward. It will be 
seen that the channels are open fore 
and aft, for the purpose of giving free 
ingress and egress to the water. But, 
in the event of stormy weather, or a 
high and rolling sea, these apertures 
are to be closed by sluice-gates, or slid- 
ing shutters; and, if necessary, the 
water is pumped out of the channels; 
by which means the wheels are closed 
in and put out of operation. The ves- 
sel then becomes, externally, the same 
as a sailing packet, and which, by sett- 
ing canvass, may be propelled by the 
power of the wind upon its sails: under 
these circumstances it will be found as 
perfectly safe at sea in stormy weather 
as any other sailing vessel of the ordi- 
nary construction. 
The specification concludes thus:

channels as passing through the hull} 
of the vessel; but, under some circum- 
stances, it may be found desirable te 
form trunks on the outside of the ves- 
sel, open at both ends, for the purpose 
of working the paddie-wheels therein, 
as above described. As we employ 
several pairs of propellers, we connect 
all the wheels on one side together by 
means of rods and cranks upon their 
axles; and all the wheels on the other 
side by tlhe same means, so as to com- 
municate the motion of the first pair 
to all the rest. We do not, however, 
confine ourselves to this or any other 
mode of connecting the wheels toge- 
ther so as to put them all in action, but 
employ geer, ora train of wheels, or 
any other means, none of which we 
claim as new or forming part of our 
invention.”’—London Journal.
