We would cali your attention to a
NEW GAS REGULATOR,
INVENTED BY
DIR. CHAs. M. ericsson.


Qate MANAGING Engineer of the Philadelphia Gas
Works, possessing GREAT DELICAOY Of adjustment
by the use of peculiar form Of va and gas holder
governing accurately single light with q capacity to
pass gas enough for the full number OF llghs and the
ability within the instrument itself to Increase tho
pressure when the greater quantity gas required
Among the peculiar advantages of this Regulator,
that make II preferable to instruments of
tracted size. which require the use of MERCURY
FLkXIBLE DIAPHRAGMs, the following deserve
especial notice -
IRsT-The tree motion OF the Regulating Valve
through considerable space gives icacy Of
adjustment, and a wider range of consumption In a
single instrument, than possible with other forms
sECoND-7he fluid seal of GLYCERINE used In this
REGULATOR, avoids the danger resulting In other
forms, from the unwhoesome vapors Mercury,
which, passing off with the Gas, disseminated
throughout II rooms in which 1t burned subjectlng
the occupants To ALL THE d DELETERIOUS EFFECTS
OF MFRCURY upon the human system and especIa Iy
upon the LUNG and SKIN when 1t is thus dlGused as
vapor. The accidental overflow of Mercury from these
mercural Seals hasi often injured valuable Gas Meters
the cost of which has necessarily been charged the
consumer.
Where the ofMERCURY in regulator is avoided
by the substitution of a FLEXIBLE DIAPHRAGM the
resulting difficulties also numerous; the la-
bility to LFAK hGE and EXPLOSION OF GAS; an
other the loss OF Flexbly and consequent lnefoiency
by age and to cold and thirdly, inherent
vice of want OF oelcacy Of adj Estmen and range OF
action.
To remedy these faults, the "CREsSoN REGULA-
TOR was invented, and wherever introduced 1t has
given the greatest satisfaction, always producing
steady light regular consumption with saving OF
from TWENTY to THIRTY Per Cent. In amount of gas
consumed.
LETTERS PATENT have been granted for this Regu-
latOr, both in the UNITED STATES and in ENGLAND,
/: is manufactured by the
AMERICAN METER COMPANY"
Of NEW YORK, PHILADELPHIA and BOSTON. for

addressed
The following is al extract from the Journal of the
FRANKLIN INSTITUTE, dated october IS, 1865 :-sAn
experimental trial then ade to the quantity of
gas consumed by the burners when under regulation tn
their maximum economy and ais the amount consumed
by the same burners when subjected to the ordinary
variations of street pressure.
~ he result showed that with the Regulator there
was uniform ly rs cubic feet gas per hour consumed
being average of 7l0 cubic feet per burner Whilst
without the Regulator the same burners consumed
from LOG 10 l4 cubic feet hour the average being 1876
cubic feet, or feet per hour to each burner"
The test apparatus which set up In the FRANK
LIN INSTITUTE E can be seen at our

In this city, where the public invited to call and
examine themselves, the amount of saving effected
by the use of the
CRESSON REGULATOR.
