Speeu OF VESSELS DouDioo Withous
Increase of Power or Danger
John Gartner's Great Invention
Patented in England and the Uni.
ted States-The Fastest Steamboat
in the World.
1t will be of much interest to our
readers to know that the estimable
mother Of the great inventor of the tri-
pie propellers. by which steamers will
run with the speed of express trains, is
in the city, on visit to her friends,
Mr.. and Mrs. Harris yewmark. Mr..
John Gartner, Of Dallas. Texas, the in.
ventor Of the new propelling power, has
discovered combination Ct forces in
the propelling Of steamboats,, by which
he increases the moving power forty
four per cent. above the previous re-
suits.
The new discovery is called the Tan
dem Propeller, and is described in the
Times Democrat of New Orleans, as fol-
lows .'The invention consists of the
attachment Of second and third wheel
to vessel SO that it will have three pro-
pellers instead of single Wheel A
propelling screw is placed on each side
of the vessel in the central part OF the
hull, in curved niche, made on each
side Of the ship so as not to offer any
increased resistance to the waves such as
side wheels offer to vessels. These side
propellers do not project beyond the
outer line of the hull, but are placed in
snch carefully prepared curved spaces as
to be entirely out of the way, only re-
stricting the size of the hold on each side
by the size of the propeller, while a
third propeller is placed in the stern in
the usual way. 1t will thus be seen that
the vessel is triple-armed with power.
The side propellers are half the size of
the stern propeller, and independent
tucicOi, 81 tuhe WhSu thS ntcth WHICH,
fails by accident to perform its Office the
side wheels supply the necessary assis.
lance. BY the use Of this triple power
the vessel must necessarily have stead
Ter motion and more uniform speed than
by the old method of propulsion. By
starting one side wheel while the other
remains stationary or turns backwards,
vessel can swing out from a pier or
wharf or turn around or change direc-
tion suddenly, property very desirable
in vessel In fact vessel made in
this way can turn around like two
wheeled cart.
The saving in fuel that turns three
wheels at the same cost as one, and near
ly double the speed, is very important.
Competent engineers assert that by
the use of the "Tandem Propeller :"
steamers can cross the Atlantic in three
days, making mere picnic affair Of such
trip. With such an engine steamer
can leave San Pedro in the morning and
arrive in San Francisco at night or leave
San Francisco ct night and arrive here
in the morning. Governor Stanford
can run with such q motor from New
York to New Orleans in two
days, and deliver freight in Los
Angeles in six days from New York,
or seven in San Francisco. via San Pc
dro, and tandem boat thence TO the
metropolis. A model Of this vessel has
been tried in St. Louis and astonished
everybody by its wonderful speed A
full report Of the trial appeared in the
ST. Louis Giobe-Democraf Of May 8,
1888. The inventor will go to England
during the present month aud bring out
his vessels on both sides of the Atlantic
at about the same time. The plan Of
the vessel has been submitted to Messrs
Mum 4 Co., Of the Scientific american,
and has been highly recommended by
these we'll known scientists and theoretic
engineers.
With such adistributed power it must
be evident to any INTEL gent person that
the new propellers must be especially
valuable in rough weather, when the
stern propeller is often out of water and
Of but lit 10 service. At such times one
or two propellers of the "tandem" kind
would be all the time in the water and
the speed of the vessel continued, as it
could not be under the former method
Of propulsion. The discovery appears
to be Of great value to the maritime
world, and the friends of Mr.. Gartner
have become so convinced of the value
of the discovery that they have prevailed
on hin to abandon his business at Dallas
and give his attention to the great dis
covery. Mr.. GARNER has accordingly
disposed of his mercantile business and
proceeded to New York, whence he
will operate in Liverpool and New York.
The merit of the discovery appears so
pronounced that the success Of the dis
coverer should be Of the most pronounced
character. Mrs. Gartner may well be
proud Of this discovery Of her son; o
fact which he carefully concealed from
her till the project seemed success,
and we trust she will long live to enjoy
his triumph
