or Rotary Motion by the Aid of Electricity, Chiefly Applicable
to the Regulation of Electric Currents.
We, FRIEDRICH Ross and ASMUS FRANZEN both of Baumgasse 3 Vienna, Austria,
Engineers 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 an improved motor for electric regulating apparatus
and has for its object to impart to the part to be governed or to some intermediate
pari suitably connected therewith the requisite movement in a direct and positive
manner.
In the accompanying drawing
Figure 1 is an elevation partly in section of our improved apparatus in its normal
position.
Figure 2 is a similar view showing a different position of the said apparatus.
Figure 3 shows a modification of our said invention. A, A, Figure 1 is a plate
laving two projections B B secured thereto to which grippers C C are pivoted. The
grippers are normally held by springs D¹ D1 D2 D² in the position shewn in Figure 1
marked, .
Between the grippers (C2 is a rod E forming part of or connected
with the part actuating the regulating devices arranged so as to be entirely clear
of the grippers CC when they are in their normal position as shown in Figure 1.
Now when the plate A A moves in a direction parallel to the axis of rod E the
springs DD2 will tend to maintain the grippers CC in their original position, while
the fulcrums B B. of said grippers move along with the plate A A thereby causing
the grippers to assume the inclined position shewn in Figure 2 and to bear against
the rod E; thus causing it to move in the same direction as the plate A A.
When the plate A A returns into its normal position the rod E will be released
from the grippers but if the plate A A continues its movement in the opposite
direction the rod E will again be moved in the same direction, as the plate A A that
is to say in a direction opposite to that in which it is moved in Figure 2 the position
of the grippers being then reversed.

page_text: If it is desired to move the rod E in one direction. only the grippers Caro
shaped as shewn in Figure 3, so that they impinge against the rod E only when the
plate A A is moved in the direction of the arrow Figure 3.
Instead of the rectilinear movement of the rod E as herein before described we may
obtain a circular movement for actuating the regulating devices by employing a ring
or annular piece instead of a straight rod E.
The reciprocating movement of the plate A A may be obtained by two electro-
magnets FF the plate A A then forming the armature; instead of electro magnets,
solenoids might be employed.
The movement of the rod E obtained as above described may in various ways be
utilised for regulating purposes. Thus it may be connected with a series of rubbing
contacts either directly or through the medium of any suitable mechanical gear so
that by the movement of the roil E resistances are thrown into or out of circuit in
which an uniform intensity of current has to be maintained. The electro magnets or
solenoids FF forming part of or being connected with the said circuit or the
rubbing contacts above mentioned may be connected with sources of electricity or
with bodies capable of inducing electric currents in the circuit to be regulated so that
by the movements of the rod E an uniform difference of potential in the latter circuit
is maintained. Or the rod E may be coupled directly or through the medium of an
intermediate gear with suitable mechanical devices for regulating the motion of the
engine or motor driving the dynamo or other device connected with the electro
magnets or solenoids F1 F2.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
11
The method of producing a rectilinear or rotary reciprocating movement by the
above described arrangement of grippers in which the movement of the plate carrying
the grippers may be produced by electro magnets or solenoids.
