Like parts are indicated by the same letter in all the figures.
A, is the armature, B the commutator, C, C, the field magnets, D, D, the brushes,.
E, the movable support therefor which together with the brushes constitutes the movable
current collector, E', E', the conducting wires, and F, the bed plate. .G, is a
plate supported on the standard G₁, and bearing the vertical guides G² G². G³, is
a shaft journalled on such frame and driven by means of the pulley G, from the end
of the dynamo shaft or other source of power. G³, is an eccentric, G6, the connecting
rod therefrom, and G7, a block driven by such rod. This block is supported so as to
reciprocate on the guide bar G³, which is secured to the vertical guides G², G², at an
angle to the reciprocating ratchet bar G. On the block G', are secured pawls Go G".
These two pawls are adjustably secured to each other by the link bars G, G". The
ratchet bar is secured to the reciprocating frame which consists of the upper bar J,
and

lower bar J. This frame is connected by the spring or elastic connection J2 with the
current collector. The bar J¹, is guided by means of the cross bars J³, J³, on the
bottom of the plate G, and is provided with a cam J, a portion of which may be
composed of a parabolic curve and a portion of a straight line at an angle to the line
of the motion of the bar; this angle is very slight and angle and curve vary according
to the inequality of action on the magnetic mass. The pawls are secured to the
block G7, by the lugs G14, G14, and such block as an aperture to receive the guide
bar G. K, is a shaft journalled at one end to an arm from one of the field magnets,
and at the other end to an arm K¹ from one of the standards G2. Rigid to the shaft is the
vibrator or magnetic mass K2, adjustably and flexibly held at its lower ends by means
of the spring K³, and thumb nut K, to the arm K³, from the bed plate F, and in a
position near one of the field magnets (). From the shaft K, projects the arm KⓇ,
adjustably secured by the set screw K', and receiving at its lower end a trunnion K³
journalled on the pawl G. Lis another arm from the shaft K; L' a spiral spring there-
from, L an elbow crank lever pivotted on the bottom of the plate G, one arm secured
to the spring L and the other carrying the trunnion L³, which travels on the cam J.
L is a spring which engages the pawl G, and by the links G2, G12, opposes the
upward movement of the arm K. The cam J, may be any shape as required and as
above explained. The two springs M, and N, are shown impinging laterally against
the reciprocating ratchet bar Go, and their office is to hold the reciprocating frame in
any position to which it has been moved by the pawls because of the spring connec-
tion J2, which tends to throw the frame back to its original position before the
inertia of the current collector is overcome and motion imparted thereto.
The use and operation of my invention are as follows:
It is not necessary to describe the ordinary operation of the dynamo or the peen-
liarities of the flow of current, or the peculiarities of the developement of currents,
in the coils of the armature or the variations of the magnetism of the field magnets
or the ordinary shifting of the current collector between the points of minimum
and maximum current upon the commutator for purposes of regulation.
Assuming that the parts are in the position indicated in figure 1, and the line
resistance permanent, the magnetization of the field magnet will be constant, and
the vibrator or magnetic mass K², will be held at a practically uniform distance
from the adjacent field magnet. If now the resistance be suddenly diminished as
for instance by the extinguishment of some of the lamps on the main line it is
desired that the current collector should rotate over toward the position shown in
dotted lines and this motion can be accomplished by the retraction of the bars J,
and J, and the spring connection J. This will only take place when the lower
pawl G, is held against its adjacent ratchet bar and in that event the reciproca-
tions of the block G, will cause the pawl to free the bar J, together with the
bars J and J2, toward the left in figure 1, thus carrying the current collector
about toward the position indicated in dotted lines. But this action only takes place
when the arm K, bears upward against the pawl G", sufficiently to overcome the
downward tendency of the spring L. This motion the arm K³, will have when
the vibrator or magnetic mass K2, is drawn with sufficient force toward the field
magnet C. The field magnet C, will draw this vibrator or mass to itself propor-
tionately to the increase of magnetism in the field magnet C, so long as the same
is unaffected by the currents in the armature. And this increase takes place as
the resistance in the line is diminished by the extinguishment of lamps or other
causes. The vibrator or mass K2 is drawn closer to its magnet C, the arm K
forces the pawl G into engagement with its ratchet and bars J, J¹ and J2 are
moved step by step toward the left in figure 1, to rotate the current collector
toward the position indicated in dotted lines. This operation continues until the
current collector has reached a position where the current is again normal. It is found
that as the current collector moves toward the position indicated in the dotted lines the
position of the neutral point of the armature so changes with reference to the field
magnet C, adjacent to the vibrator or mass K², that the resultant of the magnetism of
the field magnet C, and the currents in the armature, which resultant affects the

page_text: vibrator or mass, cannot sufficiently affect the vibrator or mass K2, and I have there-
fore supplied the compensating motor which is operated by cam J, so located on the
bar J, that as the neutral point approaches such described position the roller L³
travels along such cam J4, and by means of the spring or motor L', and the arm L,
assists in holding the vibrator or mass K³, towards its field magnet. Generally the
variation of the resistance during the greater part of this movement is not great but
as the collector nearly approaches the position indicated and the described resultant
rapidly losses its power to affect the vibrator or mass K2, the curved or parabolic
portion of the cam J*, receives the roller L³, rapidly swings the elbow lever L², and
thus increases the power of the compensating motor or spring to force the vibrator or
mass into that position which must occupy to continue the excursion of the bar J,
towards the left in figure 1, and which position the magnetism of the field magnet or
the currents of the armature or the resultant of the magnetism and the currents of the
armature are powerless to make it assume and which position it must occupy to
maintain the normal current in the exterior circuit traversed by the perfected or
generated current.
The spiral spring which is connected with the arm on the rock shaft to which the
magnetic mass is secured operates as a compensating motor. Of course many other
kinds of motor could be used in this position to reinforce or resist the action of the
magnet mass, in compensation for its change of power incident to the variation in the
magnetization of the field magnet at the point which near magnetic mass is placed ;
or in other words to the variation in the resultant of the magnetization of the field
magnet and the currents in the armature.
The shifting device or shifter for the movable collector consists substantially of the
reciprocating bar though of course other shifters may be used. This bar I call the
shifter. The block and connecting rod which are driven from the shaft of the dynamo
I term the driving motor, since they co-operate to reciprocate the shifter. Great
variations in this form of the device could be made, it being probable that even rotary
motion could be employed. The parts described as connections and so alluded to in
the claims, consists essentially of power. transmitting pieces or connection the object
being to communicate power or motion from one part to another. In the form of
device shown the operation of the magnetic mass aided at certain parts of the excursion
of the shifter by the reinforcing motor which is controlled and set in operation by the
cam is primarily to apply the driving motor to the shifter in such manner as to
secure the proper motion of the shifter. The magnetic mass may be of any shape or
character and supported in any manner and may even be of other than magnetic
material, provided only its character is. such as to make it respond as would the
magnetic mass as shown in drawings. The object is to transmit the force of power
existing in the place where such mass is located into motion or power to be applied
directly or indirectly to shifting the current collectors or to connect the driving motor
with a device to shift such collectors. When the magnet mass is located as shown,
and the lamps are being turned on, the action of a compensating motor is to gradually
decrease the action which it exercises toward such mass. It might be possible to so
place the magnet mass as that this action would be reversed and the power of the
magnetic mass would be in the first instance too great, and would require a diminishing
resisting influence from the motor instead of an increasing aiding influence as in the
form herein described. In either case the result would be the same, namely, the
compensation by such motor of the inequality of influence exercised over the magnetic
mass by the field magnet, and hence we call this the compensating motor. The
varying heights at which the pawls are held with respect to the ratchets by the arm KⓇ,
permits them to skip a greater or less number of ratchet teeth in successive excursions,
and thus to engage the ratchet at varying points along their travel as shown in
figure 5. Thus each successive excursion of the pawls may cause the ratchet to travel
unequal distances, owing to the angular arrangement of such ratchet bar with reference
to the travel of the pawls. The ratchet bar may be called a shifter when considered
independant from the motor, or if regarded as fixed thereto it may be regarded as a
part of such motor.
