54 THE COAL TRADE BULLETIN.
ALTERNATING CURRENT COAL CUTTER.
To meet the demand of the operators located
near transmission lines of the many large cen­
tral power plants producing alternating current
a new alternating current short wall coal cutter
has been placed upon the market by the Morgan-
Gardner Electric Co.
The motor is very efficient, having great me­
chanical strength and ample overload capacity.
The small number of parts assure continuous op­
eration with practically no attention. This motor
is exceptionally well ventilated. The Star-Delta
control is used which is the most simple, sat­
isfactory control for induction motors of this
capacity.
The stator can be quickly removed from the
motor body. The stator core discs are water

proofed and riveted together under hydraulic
pressure. The stator coils are form wound and
impregnated with a moisture and oil resisting
compound that will stand a high degree of tem­
perature, these coils are laid in open slots and
easily accessible.
The rotor is fireproof, the bars being imbedded
in a special moisture and heat resisting cement.
The short circuiting rings are cast solid with the
bars leaving nothing on the rotor to work loose.
The rotor shaft is exceptionally heavy with removeable
heat treated chrome nickel steel pinion.
The three self-aligning ball bearings are of
ample proportions to insure cool running and
long life, the air gap is always uniform, and the
rotor cannot strike the stator. These dirt-proof
bearings are grease lubricated eliminating all
danger of oil trouble.
The construction of the rest of this machine
is identical with the company's well known wall
type of direct current machine, embodying such
features as single reduction spur gear drive to
chain drive sprocket. Safety break washer protecting
feed cable mechanism from overload.
Means for sumping without use of extra equipment.
All parts are inclosed in a heavy rugged
frame yet easily accessible. The cutter arm is
of cast steel and the cutting chains are for heavy
duty and of single or double bit type.
A special feature is the simplicity and safety
in handling these machines. A quick acting
positive clutch and the safety break washer pro­
tects the feed cable from overload. The current
is controlled by a simple knife switch within easy
reach of the operator. By the drag line control
the operator can instantly start or stop the feed
of the machine. All operations, unloading, sump­
ing, cutting, loading and transportation is done
by power.
A self-propelling steel truck with friction drive,
reverse drive gearing and removable automatic
cable reel is used for transportation.
