Improvements in Electric Current and Current Generator Governors.
I, CHARLES WIESE, of 63 Queen Street West, in the City of Ottawa, in the
County of Carleton and Province of Ontario, in the Dominion of Canada, Machinist,
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:
My invention relates to devices for automatically and directly controlling an
electric current and regulating its source, i.e., the supply of steam, water and the
like furnishing the motive power driving the dynamo or dynamos or other
generators.
The object of my invention is a direct acting automatic governor that will
instantly relieve an electric circuit of any overcharge of current owing to the
stoppage of a part of the consumption or other cause and also at the same time
check the supply of steam, water or other source from which the power of the
generators is derived by which the current is being furnished.
Fig. 1 is an elevation of my governor, partly in section.
Fig. 2 is a transverse section of the same on line xx, showing the operating parts
in elevation.
'
Fig. 3 is a transverse section of the same on line y y, showing the other side of
the operating parts in elevation.
Fig. 4 is a transverse section of the same on line z z, showing the reel in
elevation.
A and A' are two reels having their ends a a' made of electrically non-conducting
material or lined with such on their inner faces and having each a tubular stem or
core, 2, 2, of thin non-magnetic metal, such as brass, or even nou-conducting
material. These reels are firmly bedded on any suitable support or base B, so that
their centers are in line and their adjacent ends a certain distance apart. Said
reels are wound with fine insulated wire, 3, 31, and one end from each reel is
connected to one wire L of the main line of the circuit by the wires ll', binding
posts a being provided on the reels where convenient. Each reel has a rod or
core, C, C, of soft iron, a little less in diameter than the bore of the reel tube 2, 21,
so as to slide freely therein and of about the same length as said tube. Each of
these cores has at its inner end, i.e., the ends facing each other, a square shouldered
enlargement or head, c, c', formed integrally therewith and these are connected by a
brass rod C¹ screwed into the faces of said heads and passing through a central
block or hub C of hard rubber or other non-conducting material, so that it forms
with the cores C and C' and their heads one rigid structure. The other ends of
the rods are provided with extensions D and D', of brass or other non-magnetic
material, of the same diameter and firmly screwed end on to form a rigid con-
tinuation of the cores. To these extensions are secured cross heads, E, E¹, socketed
at the jointed end and rotarily adjustable by means of a set screw E near the end
of the socket engaging a circular groove d" in the reduced neck of the pieces D
and D. Said cross heads are adapted to operate the levers F F of valves ff', or
any other controlling device. The extension pieces D and D' are supported upon
friction rollers G and G' running upon rails and g'. The latter may be secured
to the bed B or in any other convenient manner and firmly carry said extensions
and the parts attached to it, so as to slide freely backwards and forwards in the
reels A and A. For convenience of reference, the structure composed of the
cores C and C with beads c and c¹ and intervening rod C" and hub C,
.

page_text: extensions D D' and cross heads E and E', forming one rigid continuous hubbed
axle or structure, will be hereafter referred to as Z.
Upon one of the heads, c', is secured a heavy ring H of soft iron of larger
internal diameter than the head, held thereon by set-screws h, but insulated from
the head by blocks of insulation " inserted between the ends of the screws and
the head. This ring is connected with the wire L' of the main line by a wire
and another wire connects the same wire L' with the other end of the reel
wire 3 by a binding post a".
Upon the insulated hub or block C is secured a post I, having a cross head i.
It is preferably secured by means of a tube I', screwed or driven into the hub and
in which the post is screwed and secured by a jam nut I". The cross head is
prolonged upwards by an extension i adapted to carry a projecting bar or arm I¹¹
and a binding post thereon for connecting a wire Ĺ" which may be carried to
ground or connected to a resistance box. In the cross head i is pivoted a double
arm or walking beam J, the ends; and of which are screw-threaded and carry
each a disk or ring eccentrically hung thereon and adapted to make contact with
the head e and ring H below them respectively. K is a disk of soft iron, having a
rim or tire of hard rubber or other insulating material; a threaded eye being
provided near the outer edge of the metal through which one of the threaded
ends, j, of the arm J passes. K' is a ring of brass provided with a threaded eye
through which the screwed end j' of the arm J passes and above, which is provided
a binding post k', which is connected with the upper end of the reel wire 31 and
which also serves as a contact piece with the projecting bar or arm I". By giving
a turn to the disk K or ring Kin one direction or the other, they are brought
nearer to or further away from the pivot center and the leverage of the arm J is
thus decreased or increased at will.
Only one cross head, E or E¹ and corresponding valve for f¹, need of course be
used. The ring K' may be made into a disk by filling the center with hard rubber
or the like.
The device operates as follows: The disks K and K' being adjusted for a
minimum of electric current consumption on the line L L', which, with its
generators it is desired to control, so that the disk K is in contact with the head c
and the latter butted against the reel A, the axle Z and levers F and F¹ moved in
the direction opposite to that shown in the drawing and the valves and f',
which control the water or steam supply furnishing the motor which drives the
dynamo, dynamos or other generators, only partly open, then, if the consumption of
electric current increases the rings H and K' make contact and the head e abuts
against the reel A', thus moving the axle Z to the other side, reversing the
levers FF and opening the valves ff' fully, as shown in Fig. 1. When the
current rises beyond its normal strength again, either from a decrease in the con-
sumption or from other causes, the insulated disk K and head c make contact again,
breaking contact between the rings H and K' and the excess of current is carried
to ground by the wire L", while by the closing of the valves f and f¹ the production
of the generators is checked.

The axle Z, instead of being fitted with cross heads at one or both ends, may
fitted with any other desired device and may be made to operate a belt shifting or
any other controlling device for which it may be adapted.
