WINDMILL IMPROVEMENT.

Consul General julius G.. Lay, Of
Cape Town. reports as follows concern
ing a South African invention which.
it Is claimed, largely Increases the
working value Of windmills:
ain this country, where the use of
windmills is becoming more general
among the farmers, any Improvement
In wind machines finds ready sale.
The latest of such improvements Is
the Malcomess multiplication, simple
and ingenius apparatus invented and
designed in Cape Colony, which can
be used in connection with any wind
mill pumping plant, being easily at
tached to the standpipe OF any wind
mill. 1t consists Of two toothed PIN
ions which move up and down on
toothed racks attached TO neatly but
strongly designed frame. 1t Is strong
ly made throughout, takes up little
room, and requires little attention, be-
ing fitted with efficient lubricators.
"The two pinions are carried in
bracket attached to the connecting
rod Of the windmill The center rack
is attached to the pump rod, while
the side tracks are fastened with the
main frame of the apparatus to the
standpipe. SO that when in operation
the pump rod travels twice the dis
tance of the windmill connecting rod,
therefore, for instance, on an S-foot
windmill having an Sinch stroke the
pump rod would have a 16-inch stroke.
1T is claimed for the multiplication
mat by putting in a sufficiently long
cyllnger double the quantity of water
per stroke is supplied. and as the wind
mill would make the same number of
strokes with or without the multiplica-
tor double the quantity of water Is de-
liyered
I'm a 6.inch bore hole it is not pos
sible to place a larger cylinder than
5 1-2 inches in diameter This with
14-foot American windmill having
14-inch stroke would give approxi-
mately 1,200 gallons of water per hour.
but by fitting a multiplicator to this
windmill 1t would give 2S-inch
stroke, therefore, 5 IL inch dame
ter cylinder would deliver approxi-
mately 2,400 gallons Of water per hour
from a depth not exceeding 60 feet.
| This capacity is equal to that of a
7-inch irrigation cylinder, for which it
would be necessary to sink a dry well
| 40 feet deep. The usual practice Is to
| sink dry well to within suction dis
| tances of the water and use a large
diameter cylinder in this well. By
using the multiplication. 1t is claimed.
the necessity for these expensive dry
wells is done away with.
"As bore holes continue to be put
down. the underground water level
is receding and in many cases all over
South Africa windmill plants over dry
wells are ceaslng to operate, Some
means OF putting the working cylinder
nearer the source of water supply must
be devised; to deepen the dry well
would be expensive, but by using the
multiplication, the cylinder can be plac,
ed where the water was originally
struck In the bore, and a supply OF
water pumped up which would be i'm.
possible by any other means.
The writer has recently seen this
multiplication attached TO an American
windmill in operation at the Rosebank
Agricultural show, under very favor
able wind conditions, but 1t was not
pumping water from bore hole. How
the multiplication would work under
for instance, 140foot load in a light
wind"
