, the express-car and from the left socket of
the auxiliary. These bars are pushed at
an angle, fiat wise, so that when fitted in
the sockets on the two cars they are in
the form of the letter X and form most sub
stantial basis for bridge. This done the
bridge is lowered from the express trans
fer-car until its outer edge fits firmly into
the socket just below the threshold of the
door of the auxiliary car. Then the vesti-
bule coupling shoots out from each side
directly over the bridge and fits down
firmly upon it.
This is done in far less time than it takes
to relate the method of the invention and
now the iranfer of passengers from the
auxiliary to the express occurs. Both
trains are running at sixty miles an hour
ali this while and the passengers walk
across from the auxiliary to the express
just as easily and comfortably as if they
were passing from one car to another IN a
vestbule train
The transfe. complete, it is an easy
matter to replace the apparatus as it was
before the transfer took place.
Another necessary proceeding which
Mr. Dosser's invention provides for is the
transfer of baggage, and this takes place
In similar manner to the transfer of pas
sengers. The vestibuIe is not quite so
elegant, but it is constructed from the
standpoint of strength rather than ap-
pearance. The baggage is wheeled from
one train to another in the same manner
as it is hustled about railroad station,
and as the time for the transfer of passen-
gers and baggage is limited in each case
TO ten minutes there is no time to waste.
The equipment of the trains under these
circumstances must be the very best, and
it will be an absolute necessity that the
roadbed be almost faultless, for any un-
! usual variation in motion or an ugly
jump would be apt to have bad effect on
the trains and result in disaster
The feat OF running a train $50 miles
without change of engine has rarely if
ever been accomplished. Add to this the
fact that no stoppage is to be made for
either coal or water and it can readily be
seen that Mr.. Dosser's invention verges on
the marvellous. he proposes to have an
engine built with a tender that is like
nothing ever constructed of its sort in the
matter of size. OF course the fact that
there would be no stop and hardly any
slackening of speed would, in measure,
reduce the usual consumption of coal by
the locomotives that are ordinarily re-
quired to pull a train the distance men,
toned. 1t is proposed, however, that this
new tender shall be of sufficient size and
capacity to contain all the coal necessary
for the mammoth run. Water will be
taken from tanks beside the track stretch
ing along some distance, after the fashion
of the Pennsylvania fast trains.
This train that Mr.. Dosser proposes to
have all records distanced by will of
necessity have Improvements that genius
has still to conceive. For instance, the
engine must have especially constructed
journals on which provision is made to
avoid heating. Mr.. Dosser proposes that
they shall be heavier and provided with
automatic oil cups. from which is to flow
steady supply of oil. By system of
pipes it is proposed to have these oil cups
constantly replenished from the cab of
the engine, an ordinary stop cork regula-
ting the flow.
Mr., Dosser is very enthusiastic over his
invention, and believes there is no doubt
of its success il it is given fair trial.
