PLACER COUNTY INVENTOR.
VIM. Muir's Ejector for Mining and
Dredging.

VIM. Muir of Michigan Bluff, Placer
County, has recently patented an i'm
proved ejector for mining purposes and
dredging. In 1t he has grouped prin-
ciples well known to miners and ap-
piled them to dredging.
In the construction of the Muir Ejec-
tor, the inventor has followed the laws
of nature with the appliance of me-
chanical powers to get the greatest re-
suits by a hydraulic nozzle, creating
high spouting velocity through the ejec-
tor, thus causing current to such
speed as is required to carry sand,
gravel, rock or soil to the point of de-
posit, avoiding all bends or corners, as
the nearer straight the discharge the
less friction. He has avoided the fric-
ton of the centrifugal pumps, which
require power to overcome friction and
will not work in all material, as the
willows and limbs choke centrifugal
pumps.
In describing his apparatus Mr.. Muir
writes as follows:
THE patent which I have been per-
fecting for years is No. 1861 for an
ejector for mining and dredging, and
was issued TO me on December %,
1896.
THE invention relates to a device
which is especially adapted for rails
ing water, sand, mud, rock and grav-
ell from mines or depressed locations
and especially adapted for the building
or leVees and ejecting debris deposited
in river bottoms and with it fill the
low-lands long distances away. as may
be required, through pipes or dumping
! into lighters or otherwise.
1T is SO constructed that the full
power of the machine can be regulated
TO raise debris to point where desired
to be discharged, by regulating the
elective powers by screws to increase
or decrease the size of the stream in
accordance with the hight to which the
material has to be elected
THE tests / have made are four to
one but l only claim five to one, that'is
to say, 400 horse power will raise A.
OGO pounds of water to the hight of 800
feet per minute, the gross weight of the
water would be 1,320 tons per hour.
That pressure or weight would raise
that amount from the river bottom go
feet high, or it would lift 1860 tons per
hour, 20 feet above the level of the
water-that being full efficiency of the
power of 3OO feet pressure to eject de-
brls ~ feet high. With 400 horse
| power displacing in "a hours after
making allowances for stoppages, say
o4,O40 tons from the river bottom and
ejecting it any distance for leveeing
and filing in, as may be desired
The larger the machine and the
| greater the number of horsepower
used, the less will be the cost for
| handling per ton.
! This machine is especially adapted
| to be placed On boats already built.
| either steamboats, or steamships. the
! boiler power used for raising steam
used for steam pumps to supply water
| to operate electors. For instance. a
| steamer with boiler capacity of $4,000
horse power, fully equipped with mon
itors and ejector, the Nicaragua Canal
could very soon be constructed. The
power furnished by the steamers to run
! hydraulic to wash the debris after be-
ing broken up to the ejector to be
eJected through pipe, which is placed
on pontoons and carried to any point
desired TO dump debris The points
where hard rock is on the canal could
be blasted down to the level of the
canal before allowing the waters TO
| come IN TO interfere with the men
breaking up the rock.
| one OF these machines placed on a
river would handle all the debris that
! would come down from the hydraulic
mines which empty their debris into the
American River, conveying such de-
| pfls from the ejector into the malarial
/ sWampS and thus displacing the foul
waters, the fumes from which float to
the foothills carrying disease The fill
ing OF these lands would add millions
OF taxable property to the State. con-
sisting of farming lands and hydraulic
mines with the greatest boon of all
| health
This machine can be so utilized that
when person has 800 feet pressure
! with 400 inches of water it can be so
constructed to raise boulders twice the
size and twice the amount of gravel
that feet pressure and 400 inches of
! water can do.
1T is specially adapted for cities and
towns where the drainage is not suffi
cient to take off the sewerage. 1t can
be placed to raise the sewerage and
discharge it at any desired place the
water necessary being supplied by the
city water works or otherwise.
The filing in of the tule lands. the
keeping Of rivers clear from debris the
working of hydraulic mines without
hindrance, and all other industries. to-
gether with the great promotion of the
health of the State, should command
ana receive, not only the united CO.
operation of the people Of this State
but also of the United States"
