We would cali your attention to a
NEW GAS REGULATOR,
IN VENTED By
DIR. CRAS. M. CRESSON,

DIR. CHAS. M. CRESSON,
Qate MANAGING Engineer Of tho Philadelphia Gas
Works., possessing GREAT DELICACY of adjustment
by the OF peculiar form of waive and gas holder,
governing accurately single light with capacity to
pass gas enough for the full number Of lights and the
ability within the instrument itself to Increase the
pressure when the greater quantity Of gas is required
Among the peculiar advantages of this Regulator,
that make II preferable to instruments of
tracted size, which require the of MERCURY
FLEXIBLE DIAPHRAGMs, the following deserve
especial notlce:-
FIRsT-The free motion OF the Regulating Valve
through considerable space gives greater deeacy
adjustment, and wider range of consumption in
single instrument than is possible with other forms
sECoND-The fluid seal oil GLYCLRINE used In this
REGULATOR avoids the danger resulting in other
forms. from the unwholesome vapors OF 4eEcury
which, passing off with the Cas- disseminated
throughout the rooms in which burned subecting
the occupants To ALL THE DELETERIOUS EFFECTS
OF MERCURY upon the human system and especially
upon the LUNGS and SKIN, when it is thus dfused as
vapoL The accidental overflow of Mercury from these
mereura Seals hast often injured valuable Gas Meters
the of which has necessarily been charged to the
consumer.
Where the use ofMERCURY in regulators is avoided
by the substitution of O FLEXIBLE DIAPHRAGM, the
resulting difficulties also numerous; is the liza
bility TO LEAKAGE and EXPLOSION OF GAS; an
other the loss OF Flexblty and consequent nelcency
by age and exposure cold, and thirdly the inherent
vice of want of oelicacy Of adjustment, and range
action.
To remedy these faults the "CREssoN REGULA.
TOR was invented and wherever introduced it has
given the greatest satisfaction, always producing a
steady light ana regular consumption with saving OF
from TWENTY to THIRTY Per Cent IN amount of gas
consumed.
LETTERS PATENT have been granted for this ReGu-

addressed.
The following Is an extract from the journal of the
FRANKLIN INSTITUTE, dated october Is, 1865 :-"Au
experimental trial then ade as to the quantity OF
gas consumed by the burners when under regulation to
their maximum economy, and ais the amount consumed
by the same when subjected to the ordinary
variations of street pressure.
s'Ihe result showed that with the Regulator there
was uniformly 7s cubic feet OF gas per hour consumed
being an average of 7-O cubic per Whilst
without the Regulator the same burners consumed
from LOG l4O cubic feet per hour the average being l26
cubic feet, or feet per hour to each burner"

examine themselves, the amount of saving effected
by the use of the
ericsson REGULATOR.
