ARMATURE FOR ELECTRIC MACHINES.

The invention consists, general terms, in
forming armature-core which preferably
built laminae magnetizable material
insulated from each other, with diverging
40 slots openings for receiving the armature
wire ribbon, which slots are connected with
the exterior the armature openings
through which the wire may laid the
slots, and placing the wire such slots in
45 the proper manner.
This invention aims provide such means
in armature having polar projections, and
also form armature such manner as
to expose large area core-surface the
35 field-magnet poles.
Application filed June 28, 1889. The individual
plates laminae are constructed with radial 65
openings extending short distance from
the surface, and with slots oropenings b,which
extend different directions from the open
ings The slots diverge from each other at
such angles cause the two slots upon the 70
opposite sides each web thus formed to
