driving water.
1. —No coal or oil required for fuel. The only fuel required is the driving water,
and if that varies in quantity the Hydram can be adjusted accordingly.
2. —No oil required for lubrication. There are no parts whatever in our
Hydrams which require oiling.
3. —No packing necessary. There are no piston glands requiring constant
packing, or pistons requiring new leathers putting on.
4. —No cost for labour. The Hydrams require practically no attention other
than an occasional inspection to see that all is right. The majority
of our Hydrams can be left for months at a time without being even seen,
and we have known several cases where the Hydram-house door had not
been opened for several years, and the Hydram working well all the time.
See letter on page 34, regarding a Hydram that worked for seven years
without having been seen once.
5. —Little or no cost for repairs and upkeep. For evidence as to the low cost
of upkeep of our Hydrams, see Testimonials on page 10.
6. —They can be managed by a farm servant or unskilled labourer. Our
Hydrams are so simple that no mechanical or technical knowledge is
required other than the simple instructions we give.
7. —Immunity from damage during frosty weather. Blake’s Hydrams are so
constructed that they are seldom or never damaged by frost, and in
the severe winter of 1892-1893 we heard of only two Hydrams, out of the
many thousands we have fixed, being damaged by frost, and those
in so slight a degree, that an outlay of a few shillings put them right.
8. —Small storage tank only required. As the Hydrams work 24 hours per day,
and are only liable to be stopped for a very short time at once, for
cleaning, etc., very large storage tanks are not needed, and a large saving
is thereby effected.
9. — Easiness with which they can be repaired or rectified. In the majority
of cases if anything does go wrong with the Hydram, a new set of valve
clacks can be sent by letter post, and no skill is required to put them
in, as it is only a few minutes’ trouble. Our Hydrams are unique in this
respect.
10. —Our Hydrams will work with less fall and force to greater heights and
distances than any other Rams.
11. —They will raise more water and give a greater percentage of efficiency
than any other Rams.
12. —The majority of our Hydrams are almost noiseless, and work with very
little “ shock ” and vibration. Some of the Rams supplied by other firms
are so noisy that the sound is carried up the rising main, and causes
a great nuisance and inconvenience to the inmates of the house supplied
by the Ram. We have taken out many Rams by other makers for this
reason alone.
13 . —They can be adjusted to work with any quantity of driving water from
their maximum down to less than one half, so that if a Hydram be worked
from a spring which falls off considerably in dry weather, the Hydram
can be adjusted accordingly.
