1, SOPHUS CHRISTOPHER HANBERG, of 32 Tagensvei, Kopenhagen, N., in the
Kingdom of Denmark, Manufacturer; do hereby declare the nature of my invention
to be as follows:-
The present invention has for its purpose a diminution of the number of con-
stituents in a dynamo-machine to avoid as much as possible interruptions in the
magnetic circuit, to allow the magnetic-spool to be coiled on the machine and of
the use of a magnetic ground plate, thus dispensing with the non-conducting plates
which are usually more expensive.
To attain these purposes the horse-shoe-magnet is made from one piece or of
several layers parallel to the plane of the curve and the foot or base plate is so
placed as to connect non-contrary magnet poles with each other in general therefore
at any place either on the north pole-or southpole-shoe.
The coiling of the bobbin on the machine, although the magnet spool is not detachable,
as it is cast or forged together with the poles, is rendered possible by the use of but
one magnet spool, which is arranged opposite to the free space for the armature
between the poles on the part connecting the two poles, being at the same time not,
or only slightly, broader than the minimal distance between the poles. The whole
magnet may therefore, for winding the bobbin, be so secured on a rotating disc that
the axis of the bobbin coincides or approximately coincides with the axis of rotation,
so that the wire meets no obstacle in the winding.

I, SOPHUS CHRISTOPHER HANBERG of 32 Tagensvei Copenhagen N. in the
Kingdom of Denmark Manufacturer do hereby declare the nature of this invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
This invention relates to dynamo electric machines and its object is to simplify
and cheapen the construction thereof, by diminishing the number of different parts
of which the machine is composed-avoiding as much as possible interruptions in the
magnetic circuit-making the ground a bed plate integral with the field imagnets and
so avoiding the use of insulating or non magnetic bed plates which are usually more
expensive A further improvement lies in so constructing the magnets and placing
the coils thereon that the latter may be wound direct on the magnets which is necessary
when the magnets are all in one piece.
Reference being made to the drawings hereunto annexed.
Figs. 1 is a side elevation of the improved dynamo electric machine showing the
magnet and rotary armature.
Fig. 2 is a sectional end elevation thereof.
The electro magnet A is made as a horse shoe in one piece the central portion of
which forms the core for the coil and the ends the poles, the latter are suitably hollowed
at a a to receive the armature B. The distance between the points band is equal
to that between the surfaces o and c so that the coil C may be wound direct on the
body of the magnet A (with the usual insulation) by placing the magnet on a rotary
pivot or machine and revolving same in a horizontal plane, care being taken that the
axis of rotation is coincident with the axial centre of the part of the magnet on which
the coil etc. is to be wound. The horse shoe electro magnet may be of one solid
piece or of several laminae or layers parallel to the plane of the curve and the bed
plate D carrying the standards for the bearings of the armature may be made in one
piece with the magnet.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
In dynamo electric machines:
1. The horse shoe field magnet A in one part or series of laminae continuous in
the plane of the curve of the magnet and arranged so that the coil may be wound
on the central portion thereof substantially as set forth.
2. The horse shoe magnet A hollowed at a a and of substantially equal breadth
between band c c in combination with the coil C wound thereon as set forth, and
the base D integral with the magnet.
