PUMPS.

NORWICH AGAINST ALL ENGLAND, TEN POUNDS

TO A CROWN.

SHALDER'S FOUNTAIN PUMPS.
The most powerful in the world, with which a man of
ten stone weight can raise an imperial barrel of water forty-
three feet high in a minute, but with no other Pump yet tried
in a minute and a-half. Their practical gain is most extraor-
dinary, seldom below 70, and mote frequently above 100 per
',cent., taking the average of the results of every altitude from
1 foot to 100 feet high. This remarkable gain in the art of
raising water was effected in the simplest manner possible,
being merely by substituting a rolling instead of a sliding prin-
eiple for Pumps, by which their friction and leakage was abo-
lished, after the tens of thousands of bootless attempts that had
been made by the ablest mechanics in the world for 2,000 years.
For a long time after this immortal invention was publicly
introduced, a host of bullying novices insulted society by pre-
dicting that it would prove limited and frail, who are now
snivelliag about that their trade would be ruined, because
Fountain Pumps prove 300 per cent the most durable, wlie-
ther used by the power of man, horse, or steam, and they are
so economical and invariable in their action, that they cons-
manly perform for maltsters, brewers, and dyers for years with-
nut the least expense or the slightest variation. Alto, so re-
nsarkably simple, that smiths, millwrights, wheelwrights, car-
penters, &c., as well as hydraulic engineers, successfully un-
dertake their fixing and reparation. neither are Fountain
Pumps retarded, choked, nor injured by occasionally delivering
a few tons of sand, although a very little of that material soon
deranges and seriously damages the best Friction Pumps. Slowly
indeed, the art of raising water approached perfection 4,000
years ago. The beautiful Miss Rebecca brought up water from
a vi ell in a pitcher upon her shoulder for her sweetheart's
camels.
Since then appeared the four principles, namely, two limited,
and two unlimited principles—tyro of them sliding principles,
one a spiral principle, and one a rolling principle.
I t. 'The Chain-pump in action is direct and simple ; but by
friction and leakage very defective and dreadfully uncertain,
and from its numerous parts highly complicated. The Chain-
pump is a combination of inefficient expensive lumber—a
limited sliding principle.
2d. Archimedes' Screw-pump is founded upon a brilliant
idea ; but its applicability is very confined—a limited spiral
principle.
3d. Tesibies' Pipe and Poker Pump, or the Athenian Squirt.
This is the root and principle of all Piston and Cylinder
Pumps, under every name and modification. All Pumps upon
this plan are of necessity bad beyond remedy, and stupid indeed
must they be who expect the contrary, because mostly above
two-fifths of the labour employed is entirely wasted by their
friction and leakage, and when accurately tested against the
new principle, always prove to be but contemptible machines.
Nevertheless these imperfect Pumps stood unrivalled for the
last 2,000 rears—an unlimited staling principle.
4tia and last, Shalder's Pump appeared and made laughirFg
stocks of the other three Pumps, and exalted the art of raising
water to a science. The Fountain Pump is neither more nor
less than the Pump made absolute, because without any dis-
coverable defect or imperfection, it possesses every essential
property fer the purpose intended in the highest degree.
AN UNLIMITED ROLLING PRINCIPLE.
Dr. Birkbeck, President of the Mechanics' Institution, Lon-
don, says the Fountain Pump is free from the liabilities and
defects of the common Friction Pump, and approaches a perfect
Hydraulic Machine.
The Vice-President, Professor John Millington, Esq.,
F. L. S., published a work in 1830, and therein makes a rash,
false, foul, and silly assertion, that the new principle is limited,
and although, from its diminished friction it has its advantages
in some cases, it cannot be used for great elevations. Never-
theless, Fountain Pumps prove equally durable for lifts above as
below one hundred feet. Millington might surely have known
that flexibility was no proof of frailty, nor rigidity of dui ability.
The rigid teeth of mamma and her four sisters were mostly
gone, but their flexible tongues remained in full activity when
their ages, united with their only brother, exceeded five hun-
drod years. And the Connectors or (flexible Cones) in Foun-
tain Pumps prove also not only surpassing durable, but ahnest
i ndes .kruc table.
11
CASES SUFFICIENT.

Thirty Fountain Pumps, that cost above 1,0001., have net cost
2/ per year for all the connectors, though twenty-four of them,
from fifteen to one hundred feet long, are used to water the
public roads from Wymandham to Aylsham, and at Yarmouth.
A Treble-acting Fountain Pump at Diss brewery (horse
power) the connectors lasted five years, lift one hundred feet.
N.B. It is the packing that scrapes up the water in the o!il
Pump that wear, out. And it is the connector that rolls up
the water in the New Pump that wears out.
Mark the next two cases, both Pumps having done the same
work.
A Single-acting Fountain Putr•i at Messrs. Horton's, dyers,
Norwich (manual power). He the connectors of the New
Pump last four times as long as did the pa -king of the old
Pump it superseded.
A Double-acting Fountain Pump at Messrs. Stark's, dyers,
Norwich (steam power). Here also the packing of their old
Treble-acting Pump (superseded) used to last about three
months, now the ttonnectors of their new pump last above six-
teen months. This noble machine has not cost as. a year for
connectors, though constantly at work, and delivers eight im-
perial barrels of water per minute, PRACTICALLY PROV-
ING THAT IN SKILFUL HANDS THE NEW PRIN-
CIPLE IS DECIDEDLY THE MOST DURABLE.
The Seven Read Fountain Pumps, fixed early in l i3B, be-
tween Norwich and Aylsham, have not cost a shilling, nor
varied in effect.
The Ten Friction Pumps (alias Pumplings) mixed with
them, have often been repaired, and the other day not one of
them would answer the helm—so much for comparative frailty.

EFFECT.
At the many fair trials made by mt, horse, and steam
power, the rolling principle beat the sl►ding principle, upon an
average, nearly eighty per cent., in raising water, 10, 20, 30,
45, and 70 feet high, and volumes of testimonials, by land and
sea, certify similar results.
'But, whereas there are still many novices striving hard to
perpetuate ignorance and the Athenian spurious Pump in pre-
ference to the New English genuine Pump and common sense,
pretending that they can make miraculous fr►cti_n Pumps with-
out friction,
Therefore, let us at once come to deeds to try the (files-
tion, and shame the fool who first cries " Hold, enough."
CONDITIONS OF PROPOSED TRIALS AGAINST
TIME.

Take four Pumps of the Old Plan, and four Pumps of the
New Plan, with mechanical parts alike, and so adjusted that a
man of ordinary strength may exert his full force, and raise with-
out stopping nine imperial barrels of water five feet high, three
barrels fifteen feet, one barrel fifty feet, and nine imperial gallons
of water 200 feet high, or over the London Monument.
The number of seeoncio required with one pump less than
with the other, will be its gain in time and labour.
The coT.petitors should fine the pumps and the public the
pipes, in order to prove that engineers of the old school knew
as much about raising water as sucking monkeys.
Well, after all the stupid, lying, and even destructive oppo-
sition (Neomarket to wit), the graduated scale of the Foun-
tain Pump is practically and successfully carried out from the
delivering cf a single pint of water per stroke to the delivering
of 6,000 imperial gallons of water per minute.
And now to congratulate all nations upon the complete suc-
cess of an invention of boundless and undying utility, which
nature bars surpassing, is highly gratifyine,

P.S.—No work is worse done titan that of raising water.
Respecting force and resistance both town and country
Pump-makers seem most gloriously ignorant.
I inquired of two men pumping,
between London-bridge and
the Tunnel, how long it took them to fill their six-barrel water
cart, lift thirteen feet?—Answer : About seven minutes, quick
working.
With a No. Six New Plan they could have done tho litre
work in seventy seconds.
One Fountain Pump would about equal all the three Cockney
built Friction Pumps at the Queen's Barracks, Norwich.
