Vacuum Auto Sweeper
HEBE is a new German street •weep
ing device now in use in Berlin,
the cleanliness and beauty of which city
now mirpnUOl even Paris. The motor
Dot only furnishes driving power for the
wagon, l>nt runs the brushes ami fan, the
dirt being naked into a funnel, from
which it is conveyed to cans, which are
easily removed to empty. The motor is
at 80 horse power, and the machine
sweeps a track seven feet widu at the
rate of eleven miles an hour.
Antarctic Motor Sleigh
CAPT. SCOTT, the English explorer,
has tried out the sleigh which ho
intends to take with him in his search
for the south pole; and he considers that
it "ill prove n great help to him on h'.s
expedition. As will be seen from the
picture, the driving wheels do not touch
the ground; ;m endless chain fitted with
spuds and pattens passes over thesa
wheels and sides under each runner. The
appearance when the sledge is moving is
very curious, as the chain where it
touches the ground seems to stand still
while the sledge slides forward over it.
This, in fact, is what actually takes
place, the upper chain traveling forward
at twice the speed of the sledge.
French Auto Searchlight
THIS fine machine is onp of the de
velopment! of tlie automobile, and
is likely to be extremely useful in civic
as well as military work. One great ad
vantage if tli.it the searchlight may bo
operated while the automobile is speed
Ing along at the rate of sixteen miles
an hour, the eighteen horse power engine
bring ample to provide for both opera
tions. The light is of 7,000 candle
power, and the machine is geared to
take a gradient of 15 per cent The
French war oflice has ordered a num
ber of these machines, believing that in
them they have something superior to
those devised by any other country. The
auto searchlight has been found of prac
tical value in certain American fire de
partments, but the ultimate superiority
of a vehicle driven by the same power as
that which supplies the light over that
of a horse-drawn wagon appears to be
unquestioned.
English Walking Engine
THE English walking engine, which
has been in demonstration for
nearly a year, has been perfected to the
extent that it is now a commercial
proposition. Moreover, a five-ton tender
on the same principle is an adjunct to
the engine. The advantages of the in
vention are that it walks on its own
track, and is thereby enabled to tra
verse what would be impossible ground
for the ordinary type of vehicle. Soft
sand, swampy ground, ditches and ob
structions of various sorts are covered
without difficulty, and the utilitarian
value of the invention is already plainly
apparent.
