''Gas-lighting by electricity has be-
come another great convenience adj
ded the reporters informant. ''As APP
piled to private residences it is of two
systems, the pendant and the automatic.
The latter system embraces several
kinds of burners. the one most general
~ in use being the rachel. 1t obtains
its name because it has a raehet-wheel
governing a stop-cock so arranged with
4 pawl and spring that one pull of the
chain turns the wheel one notch for
ward, bringing one of the gas-ways of
the gas-cock in direct line with the bur
ner gas-way. thus turning on the gas,
and, ut the same time, through clectri-
cal connections, lighting it. The next
pull of the chain turns the rachet-wheel
another notch, and the gas is turned off.
The plain pendant differs from the other
in that it does not operate stop-cock.
but simply lights the gas after it is
turned on by the ordinary key. II is
especially useful in stores, or in the
kitchen, where the rachet-burner is not
necessary, and at the same time materi-
ally reduces the cost and the possibility
of the gas being left escaping where the
burners are subject to the use of careless
and ignorant persons. Argands are
fitted both as rachel and plain pend
ants, and they differ from the common
burners, only in having argands instead
of the common burners above the stop
cock. In regard to gasoline pendants,
any burner can be fitted to light by
electricity
"What is the automatic systemp'
"It is that by which the gas Is lighted
and extinguished from some distant
point by buttons placed in the wall for
that purpose, and consists of the auto
matte burners and the push buttons, or
KEYS for lighting them. In the auto
matte the electricity not only lights the
gas. but also turns it OH and of. This
il done by two pair of electromagnetic,
one on either side of the gas-way, gov
erning an armaturc, which. by lever.
operates the gas-cock. Thus. when an
electric current is obtained through one
of the magnets, the armature is attract
cd to that magnet and the lever moves
the stopcock and turns on the gas. and
when the current of electricity is in
duced in the other magnet, the arma-
turc is drawn in that direction, thus
turning off the gas. This system is not
adapted for general use in a house, for
in most places, us on chandeliers, the
pendants are much more convenient
and cost very much less; but in few pl;l-
ces the automatic is almost indispensa-
ble One in the front hall, to be light
cd by buttons, placed at the front door,
and also by the chamber door, or one
in the basement. with PROSECUTIONS or
keys at the head of the basement stairs,
and at some convenient point in the
basement. or i'm the slceping-room, to
be lighted from the bedside and room
door, are all Iuxuries which, after ac-
customed use, become necessities to
household comfort The electric bur-
ners cost from 81 to $3.50 each. N. J..
