A NEW ELECTRO- MOTIVE POWER
Year: 1874

page_text: LETTERS PATENT to William Richardson Bigsby Chamberlin, Captain
in the 24th Regiment of Foot, for the Invention of "A NEW ELECTRO-
MOTIVE POWER."
Sealed the 23rd June 1874, and dated the 5th January 1874.
PROVISIONAL SPECIFICATION left by the said William Richardson
Bigsby Chamberlin at the Office of the Commissioners of Patents,
with his Petition, on the 5th January 1874.
I, WILLIAM RICHARDSON BIGSBY CHAMBERLIN, Captain in the 24th
Regiment of Foot, do hereby declare the nature of the said Invention
for "A NEW ELECTRO-MOTIVE POWER," to be as follows:-
A pendulum having sliding cross bars on it. These cross bars are
armed at each end with either a magnet or steel. There are also magnets
at both sides of the pendulum, which are placed at such a distance from
the pendulum that they in turn attract the cross bars, drawing the
pendulum from the perpendicular. The current of electricity is trans-
mitted and suspended by clockwork regulating the pace of the pendulum,
the pendulum giving the motive power to the machine.

Great Seal Patent Office on the 4th July 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
RICHARDSON BIGSBY CHAMBERLIN, Esquire, Captain in Her Majesty's
Twenty-fourth Regiment of Foot, now serving in England, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent bearing date the Fifth day of January, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Richardson Bigsby Chamberlin,
Her special licence that I, the said William Richardson Bigsby Cham-
berlin, my executors, administrators, and assigns, or such others as I,
the said William Richardson Rigsby Chamberlin, my executors, admi-
nistrators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "A NEW ELECTRO-MOTIVE
POWER," upon the condition (amongst others) that I, the said William
Richardson Bigsby Chamberlin, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and :
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said William Richardson Bigsby
Chamberlin, do hereby declare the nature of my said 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 consists of a pendulum having sliding cross bars on it.

page_text: at such a distance from the pendulum that they in turn attract the cross
bars drawing the pendulum from the perpendicular. The current of
electricity is transmitted and suspended by clockwork, regulating the
pace of the pendulum, the pendulum giving or furnishing the motive
, power necessary to move or work machinery.

page_text: as before, only to the opposite side, and so on through the series, when
the beam shall be in its original position.
The heads of the cross bars shall be of either soft iron or electro-
magnets, and the short cross bars shall be also so fastened that they can
be drawn to the right or left as may be required.
: The electro-magnets shall be at equal distances from each other and
arranged in two rows, one on either side of the beam at equal distances
from the same in its normal position parallel to two radii of the circle,
the centre of which is the pivot on which the beam works, and each the
same distance from the radius to which it is parallel as the centre of the 1
beam is from the exterior of the head of a cross bar when pressing
against it. The angle at which the above mentioned radii subtend each
other depends on the number of the cross bars and their distance from
the pivot.
The electricity shall be supplied by two batteries to the alternate 1
magnets in their order for drawing the cross bars. One pole of each
battery shall be in direct communication with half the number of
magnets. The other pole of the batteries shall each pass through a
hand rotating round a dial, to which are fixed at equal distances com-
munication to the magnets, and in such order that when the hand has 2
supplied electricity to a magnet the next communication shall be to the
next alternate magnet for drawing the beam.
The communicators shall be fixed to the dial, but insulated from it
and in such a manner that when a magnet has drawn the cross bar to it
the cross bar shall by ordinary mechanical means displace the communi- 2
cator and allow the hand to pass to the next one till it in its turn gives
way and allows the hand to pass to the next, and so on.
In the accompanying Drawing the beam is marked 'A', the cross bars
(B1, &c., and C1, &c.); the magnets are numbered 1, 2, 3, &c., the dials
D and E, the hands F, G; the communicators are marked H, 1, 2, 3, 3
&c., and correspond with the numbers of the magnets in this plan. I
show 24 magnets, 12 on each side of the beam, of which 1, 2, 5, 6, 9,
10, 13, 14, 17, 18, 21, 22, have one pole in direct communication with
the battery that supplies electricity to the hand F of the dial D, on
which are fixed the communicators of magnets in the following order, 3
1, 5, 9, 14, 18, 22, 13, 17, 21, 2, 6, 10, and in like manner the magnets

page_text: 3, 4, 7, 8, 11, 12, &c., are attached to the dial E in the following order,
3, 7, 11, 16, 20, 24, 15, 19, 23, 4, 8, 12.
my
In model I have made the dial of brass, on which are fixed pieces
of ebonite projecting beyond it, in which are cut notches. In these
notches I fix by means of a pivot small brass bars, the upper part faced
with platinum. The magnets are attached to these in the ordinary
manner, and to the lower part I have fixed wire which is led to a piece
of wire projecting about the sixteenth of an inch beyond the magnet,
so that on the cross bar coming to its magnet it must push in the pro-
jecting piece, which in its turn pushes or pulls the lower end of its brass
bar, the communicator, under the dial, and so releases the hand (made
in platinum) and allows it to pass to the next one.
In model I use
ordinary clockwork to make the hand rotate, and with a fly wheel
regulate its pace.
my
Having thus described the nature and objects of my said Invention,
I declare that what I claim and desire to be secured to me by the herein-
before in part recited Letters Patent is, the Invention of a new electro-
motive power obtained by the means and in the manner herein-before
described and illustrated on the Drawings for the purposes of moving
and working machinery or any modification thereof.
In witness whereof, I, the said William Richardson Bigsby
Chamberlin, have hereunto set my hand and seal, this Second
day of July, in the year of our Lord One thousand eight hundred
and seventy-four.
