A 81 louis genius claims TO have solved
n iouo-standinr enigma In marine architec-
t,lre. by which the ocean can be trayersed
~ t5res DAYS. The model seems very much
like an ordinary acrew vessel, modelled az
tor an entirely new design. The boat Is
nronel,cd by steam, which Is generated In
boiler located In the forward part, near
the bow, This force Is conducted through
separate tubes TO three diminutiye cylln-
dcrs, which set as many shafts In motion.
one shaft projects at the stern. aud, In re-
volyinc. turns a screw wheel OF the pattern
commonly used on steamships. The pecu-
liar feature of the boat is the arrangement
by which two screws are inserted in re-
cess on each quarter below the water line
and about onc-third Of the boats length
from the PROV, about under the foremost.
By admitting steam TO the cylinder the
machinery Is started, and presently the side
and stern fans begin churning the water
with a vigorous stroke. which sends the
vessel flying the full length OF the tank IN
few seconds. The momentum Is so great
that II requires the full strength OF the eN-
| hibitor TO stop its progress and proven,
disastrous collision with the end OF the
clstern. In trial the engineer in charge
applied steam TO the two side cylinders ana
allowed the stern fan to remain motionless
and act as drag. Despite the incumber-
ance. the boat shot forward with remark
able velocity. Subsequently the side screws
were left idle, and the power OF the stern
wheel ouly used. The boat moved forward
gracefully and easy until steam was admit
ted TO the port and starboard engines. when
! II rcdoubled its speed instantly, and sprang
| forward os il 1t had been a light prolectile
forced from catapault. The model had
not been fitted with rudder, and the en-
gineer proceeded to display the steering
qualities. The starboard engine was set
dead ahead and the port screws were work.
| ed hard astern- The result was astonishing.
The little craft, after gaining Roadway,
whirled around, describing an arc OF cir
Gle, until it was stopped by the sides OF the
cistern, which was not wide enough TO al-
low complete swing. IL seemed to turn
on pivot. and rs the action OF the engines
was reversed the boat answered promptly,
and without any other assistance went
about in the other direction. Mr.. Gartner
was the inventor, and had secured letters
patent in the United States and foreign
countries. BY the addition OF the side
screws in recess which did not interfere
with the mold of the ship ne calculated TO
double the speed Of ocean vessels, and
make the trip in three days. The engines
could be used as auXillaries, or as comoi-
nation, although in their independent form
they would be of eminent service in steer
ing by enabling steamship to turn around
III It's own length. The invention is adapt
ed to any marine vessels of the present
style OF construction, which can be re-
modelled cheaply. The use of the second
screw Oh the side-shafts is intended TO aid
in discharging the water received from the
first screw, and by that means to save iric-
ton. The theory is simple, and as demon
strated by the practical test OF the mode
seems feasible. Mr.. HeXter, one OF the
partners, returns TO Dallas in order to az
range his business affairs. and will then
submit his patent and model to n critical test
in the East in company with the inventor,
and will sail for England about the middle
of June. AS vessels OF single or OF twin
screws have to almost double the amount
OF fuel and labor in the fire-room for every
knot increased over eight knots, this inven-
ton will work revolution in steam engi-
neerinE.
