Year: 1861

page_text: LETTERS PATENT to John Reeves, of the City of New York, in the
United States of America, now residing in London, in the County of
Middlesex, for the Invention of "IMPROVEMENTS IN ELECTRO-MAGNETIC
ТИМАТ ТАТТО
ENGINES FOR OBTAINING AND APPLYING
PROVISIONAL SPECIFICATION left by the said John Reeves at the
Office of the Commissioners of Patents, with his Petition, on the 16th
September 1861.
I, JOHN REEVES, of the City of New York, in the United States of America,
now residing in London, in the County of Middlesex, do hereby declare the
nature of the Invention for "IMPROVEMENTS IN ELECTRO-MAGNETIC ENGINES FOR
OBTAINING AND APPLYING MOTIVE POWER," to be as follows:-
This Invention has for its object improvements in the combination and
arrangement of the several parts of electro-magnetic engines, and these
improvements apply more particularly to that arrangement of apparatus for
which a Patent was granted to me, and dated the 22nd day of February 1861,
No. 449. My present improvements in electro-magnetic engines consist in
supporting a slotted ring or wheel on studs projecting from the fixed plate
which supports the apparatus, and on this slotted ring or wheel holders are
placed, through which the wires from the galvanic battery and helices pass
and are brought in contact with another ring or wheel formed of non-

page_text: conducting material with spaces in the rim, which hold conductors. This
ring or wheel is attached to the driving wheel, and when in motion makes and
breaks contact continually between the wires from the galvanic battery and
the helices. The surface of the ring or wheel for making and breaking
contact is prepared with sand, emery, or other suitable material, so as to cause
friction, and thus rub and clean the ends of the wires as they pass over it
from the "fuse" or "glaze" produced by the action of the electro current
when in contact, by which arrangement a great obstacle is removed which has
hitherto existed, and has prevented the full power of the battery from reaching
the helices. A lever is employed to change the position of the slotted ring
before mentioned, and with it the wires which pass to the wheel or ring which
makes and breaks contact with the galvanic battery, and by this means I
regulate the speed and reverse the direction of the engine to produce a back-
ward or forward motion as required.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by tho said John Reoves in the Great Seal Patent Office on
the 15th March 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, Jonn
REEVES, of the City of New York, in the United States of America, now
residing in London, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of September, in the year of our
Lord One thousand eight hundred and sixty-one, in tlio twenty-fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said John Reeves, Her special licence that I, the said John
Reeves, my executors, administrators, and assigns, or such others as I;
the said John Reoves, my executors, administrators, 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
"IMPROVEMENTS IN ELECTRO-MAGNETIC ENGINES FOR OBTAINING AND APPLYING
MOTIVE POWER," upon the condition (amongst others) that I, the said John.
Reeves, my executors or administrators, by an instrument in writing under my,
or their, or one of their hands and scals, should particularly describe and ascer-
tain the nature of the said Invention, and in what manner the same was to bo

page_text: 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 John Reeves, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say :-
This Invention has for its object improvements in the combination and
arrangement of the several parts of electro-magnetic engines, and these
improvements apply more particularly to that arrangement of apparatus for
which a Patent was granted to me, and dated the 22nd day of February 1861,
No. 449. My present improvements in electro-magnetic engines consists in
supporting a slotted ring or wheel on studs projecting from the fixed plate
which supports the apparatus, and on this slotted ring or wheel holders arc.
placed, through which the wires from the galvanic battery and helices pass,"
and are brought in contact with another ring or wheel formed of non-
conducting material, with spaces in the rim, which hold conductors. This
ring or wheel is attached to the driving wheel, and when in motion makes
and breaks contact continually between the wires from the galvanic battery
and the helices. The surface of the ring or wheel for making and breaking
contact is prepared with sand, emery, or other suitable material, so as to cause
friction, and thus rub and clean the ends of the wires as they pass over it
from the "fuse" or "glaze" produced by the action of the electro current
when in contact, by which arrangement a great obstacle is removed which has
hitherto existed, and has prevented the full power of the battery from reaching
the helices. A lever is employed to change the position of the slotted ring
before mentioned, and with it the wires which pass to the wheel or ring which
makes and breaks contact with the galvanic battery, and by this means I
regulate the speed and reverse the direction of the engine to produce a back-
ward or forward motion as required.
And in order that my Invention may be most fully understood and readily
carried into practice, I will proceed to describe the Drawing hereunto
magnetic engine or apparatus for obtaining and applying motive power, having
my improvements applied thereto; and as the nature and working of an
electro-magnetic engine or apparatus of this character was fully described in

page_text: the Specification of a Patent granted to me, and before referred to, it will only
be necessary for me to describe those parts of the apparatus which relate to
my present improvements.
A is the toothed magnet ring, composed of alternate surfaces of iron and
brass, or other non-magnetic material. The magnet ring A is arranged and
supported so as to rotate through a series of helices or coils of insulated or
covered wire C fixed on the stationary plate or framo B. d is a ring (or it
might be a segment of a ring) formed with slots d', through which the studs d²
pass to support the ring, and upon which it is capable of being moved partly
round by means of the lover d' affixed thereto, as shown. The studs d aro
fixed in the plate e, which supports one end of the main driving axis E of the
machine. Upon the ring & plates d* of non-conducting material are fixed, to
which the holders d³ are attached which carry the metal springs or conductors
fand f, the springs f being constantly in metallic contact with the fixed
metal surfaces g and wires g₁ from the helices, whilst the ends of the springs
or conductors serve to make and break contact with the wiro h from the,
battery by pressing upon the surface of the ring of non-conducting material i
-fixed on the main axis E. Metallic conductors ; aro let into the rim of the
ring i at suitable distances apart, which are in metallic contact with the wire
from the battery, so that when the apparatus is in motion the alternate
surfaces of conducting and non-conducting materials on the ring i successively
act-to make and break the circuit of the electric current, and by applying a
little adhesive matter to the surface of the ring i, and sifting a little fine sand
or emery thereon, the friction caused thereby when the apparatus is in motion
will rub and clean the ends of the springs or conductors f¹ from the oxydation
caused by the electric spark, by which a very beneficial result in the action of
such apparatus will be obtained. By moving the lover d³ in one direction or
the other to change the position of the slotted ring d, and with it tho relativo
positions of the springs or conductors f¹ which make and break contact with
the galvanic battery, I am enabled readily to regulate the speed and reverse
the direction of the engine to produco a backward or forward motion as
required.
Figure 3 shows another arrangement of the springs or conductors f, f¹, and
of the mode of connecting the wire h from the battery to the break wheel i,
by which the contact pressure of the springs or conductors f, f, and the wire h
can be adjusted, all which will be readily understood on examining the
Drawing.
When two or more magnetic rings are mounted and arranged so as to act
on one main shaft, the magnetic and non-magnetic divisions on one should be

page_text: even in number, and on the other they should be odd; for instance, one ring
may have six spaces of magnetic material, and six of non-magnetic material,
and the second ring may be arranged with five or seven spaces of the magnetic
and non-magnetic material, and the helices on each ring must be arranged in
equal numbers with the magnetic spaces of its respective ring, and the springs
or conductors to make and break contact between the battery and helices may
be in number more or less as may be required to connect and disconnect the
current between the helices and the battery.
In witness whereof, I, the said John Reeves, have hereunto set my
hand and seal, this Fifteenth day of March, in the year of our Lord
One thousand eight hundred and sixty-two.
