(Iate Managing Engineer of the Philadelphia Gas
Works, possessing GREAT DELICACY of adjustment

Among the peculiar advantages OF this Regulator,
that make 1t preferable to instruments of more
tracted size, which require the of MERCURY or
FLEXIBLE DIAPHRAGMs, the following deserve
especial notice: .N4 .I.'f. 4l
FIRsT-The free motion OF the Regulating Valve
through considerable space gives grea decacy

single Instrument than is possible with other forms

Where the use of MERCURY in regulators is avoided
by the substitution of FLEXIBLE DIAPHRAGM. the
resulting diicuies also numerous; one Is the LA
bnity to LEAKAGE and EXPLOSION OF GAS: an
other the loss OF FlexbIy and consequent inefciency
by age and exposure to cold and thirdly, inherent
vice of want OF 0elcacy Of adustment and range of
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 er Cent IN amount of gas
consumed.
LETTERS PATENT have been granted for this Regu-
lator both in the UNITED STATES and in ENGLAND.
Il is manufactured by the .r
"AMERIcAN METER COMPANY,
Of NEW YORK, PHILADELPHIA, and BOSTON, for
alone and sale, Wholesale and Retail ware
houses in this city where all orders and letters should be
addressed.
The following is an extract from the Journal of the
FRANKLIN INSTITUTE, dated october l6 1865 IAN
experimental trial then made to the quantity of
gas consumed by the burners when under regulation TO
heirmaxmum economy, and also the amount consumed
by the burners when subjected to the ordinary
variations of street pressure.
- he result showed that with the Regulator, there
uniformly Is cubic feet gas per hour consumed
being average of 7-lO cubic feet per burner Whilst
without the Regulator the same burners consumed
from lO 10 4O eubic feet per hour the average being 26
cubic teet, or feet per hour to each burner"
The test apparatus which was set up in the FRANK
LIN INsTI1 UTE can be at
SCALE WAREHOUSE
In this city where the public are invited to call and
examine Tor themselves the amount of saving effected
by the use of the
CRESSON REGULATOR.
