by insulation, said plates having diverging
slots for receiving the armature-conductors

such openings being approximately equal to
the width the slot.
The connections between the armatu re-coils

verging slots for receiving the wires, said slots
leaving intervening webs, and coils wire
wound said slots. Uptegraff,.
In testimony whereof have hereunto
subscribed our names this 25th day June,
A. armature-core for electric machines,
consisting plates magnetizable material
30 sepai’ated insulation, having radial open
ings intervals, slots diverging from said
openings for receiving armature-coils, and
windingblocks orclips the ends the core.417,794
described found very efficient its
operations and the same time simple in
its construction. 45
7. core for electrical machines, composed
to plates magnetizable material separated
by insulation, said plates having diverging
slots for receiving the armature-conductors
and opening the exterior the plate at
the origin the diverging slots.
15 core-plate for electrical -machines,
stamped with diverging slots intervals near
its periphery and opening the periphery
at the angle formed each two diverging
slots.
