"
York, Mechanical Engineer, for the Invention of IMPROVEMENTS IN ELECTRIC
MAGNETS AND IN MAGNETIC MOTOR ENGINES."
Sealed the 24th April 1878, and dated the 27th October 1877.
PROVISIONAL SPECIFICATION left by the said Michael Holroyd Smith
at the Office of the Commissioners of Patents on the 27th October 1877.

Engineer. "IMPROVEMENTS IN ELECTRIC MAGNETS AND IN MAGNETIC MOTOR
ENGINES."
وز
This Invention relates,-
Firstly. To an improved construction of electric magnet.
Secondly. To an improved construction of magnetic motor engine, in connection
with which are electric magnets, so arranged and operated as to render the
maximum power of the magnet available as the moving force for propelling the
engine.
Magnets made according to this my Invention comprise a coil of copper wire
resting upon an iron base plate, by preference, but not necessarily, circular, and
surrounded by an iron case attached to the base plate. The armature consists of an
iron plate, the size of the case, and an iron core of such size and shape as to fit and
slide into the copper coil, so that when the core reaches the base plate the armature
disc also touches the top of the cylindrical core.
Or part of the core may be attached to the base plate, and part only left attached
to the armature disc.
Or the base and armature may both consist of a core and case, each partly filling
and partly covering the copper coil.
Or the copper coil may rest upon the base plate, having the iron core attached
to it, and the armature consist of a disc carrying the case or core made to slide over
the coil.

page_text: An electric motor engine, constructed and operated according to this my Invention,
comprises a series of magnets arranged at distances apart, forming a circle, above
which is a disc resting on a pivot; the outer edge or diameter of the disc carries or
forms the armatures directly above the circle of magnets. The armature disc
being tilted, one portion of its outer diameter approaches one or other of the
magnets.
In operation the apparatus works as follows:-As each magnet is charged it
attracts the armature dise, and when the point of contact between the first magnet
and the armature disc is reached a contact breaker operates, and the next magnet of
the circle becomes charged; and in turn when the armature disc reaches the second
magnet, the contact breaker again acts, and so on round the entire circle of magnets.
The armature disc is thus caused to oscillate on its pivot, and "wobble" or roll
upon its outer rim or edge. The motion thus obtained is by shaft and crank or
other like contrivance converted into rotary motion.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Michael Holroyd Smith in the Great Seal Patent Office on the 24th

This Invention relates,-
Firstly. To an improved construction of electric magnet.
Secondly. To an improved construction of magnetic motor engine, in connection
with which are electric magnets, so arranged and operated as to render the
maximum power of the magnet available as the moving force for propelling the
engine.
Magnets made according to this my Invention comprise a coil of copper wire
resting upon an iron base plate (by preference, but not necessarily, circular), and
surrounded by an iron case attached to the base plate. The armature consists of an
iron plate, the size of the case, and an iron core of such size and shape as to fit and
slide into the copper coil, so that when the core reaches the base plate the armature
disc also touches the top of the cylindrical case.
Or part of the core may be attached to the base plate, and part only left attached
to the armature disc.
Or the base and armature may both consist of a core and case, each partly filling
and partly covering the copper coil.
· Or the copper coil may rest upon the base plate, having the iron core attached
to it, and the armature consist of a disc carrying the case or cover made to slide
over the coil.
An electric motor engine, constructed and operated according to this my Invention,
comprises a series of magnets arranged at distances apart, forming a circle, above
which is a disc resting on a pivot; the disc carries armatures directly above: the
circle of magnets. The disc being tilted, one portion of its outer diameter and the

page_text: armature attached approaches the magnets. The armatures are hung or hinged to
the disc, so as to permit the disc to continue its movement when the armatures are
intercepted by the magnets.
In operation the apparatus works as follows:-As each magnet is charged, it
attracts the armature, and when the point of contact between the first magnet and
the armature is reached, the contact breaker operates, and the next magnet of the
circle becomes charged; and in turn, when the armature disc reaches the second
magnet, the contact breaker again acts, and so on round the entire circle of magnets;
and by reason of the armatures being hung or hinged, as described, the full power
of the magnet is available when the crank is at right angles to the armature and
magnet in operation.-.-
The arrangement described is applicable to beam engines as well as to oscillatory
disc engines. The armature disc is thus caused to oscillate on its pivot, and
"wobble" or roll. The motion thus obtained is by shaft and crank or other like
contrivance converted into rotary motion.
:
Such being the nature and object of this my said Invention, I will now
proceed to describe the same in detail, and in order that the Invention may be
fully understood, I have annexed two Sheets of Drawings, in which,-
Fig. 1 is
vertical elevation of a magnet made according to this my Invention.
At A is a coil of copper wire resting upon an iron base plate B (by preference,
but not necessarily, circular), and surrounded by an iron case C attached to the base
plate.
The armature consists of an iron plate D; the size of the case and an iron core E
of such size and shape as to fit and slide into the copper coil A, so that when the
core E reaches the base plate the armature disc D also touches the top of the cylin-
drical case C.
Fig. 2 is a like elevation, shewing magnet in which part of the core E is attached
to the base plate B, and part left attached to the armature disc.
Fig. 3 is another modification in which the base B and armature D may both
consist of a core and case, each partly filling and partly covering the copper
coil A.
Fig. 4 is a modification in which the copper coil A may rest upon the base plate B,
having the iron core E attached to it, and the armature D consist of a disc carrying
the case or cover C, made to slide over the coil.
Fig. 5 is a modification in which the base plate B has a hole in its centre,
so as to allow the core E to slide through it, the armature disc D has a cylin-
drical case, so arranged as to slide over the core; d, d, d, are the points of contact.
When the current is broken, the armature and core are free to slide or move
forward.
An electric motor engine, constructed and operated according to this my Inven-
tion, comprises a series of magnets M (see Figures 6, 7, and 8), arranged at distances
apart, forming a circle, above which is a disc N resting on a pivot P, the disc carries
the armature R directly above the circle of magnets M. The armature R is hung
or hinged to the disc N, so as to permit the disc N to continue its movement when
the armature R is intercepted by the magnets M.
In operation the apparatus works as follows:-As each magnet M is charged, it
attracts the armature R, and when the point of contact between the first magnet
and its armature is reached, the contact breaker operates, and the next magnet of
the circle becomes charged; and in turn when the armature disc reaches the second
magnet the contact breaker again acts, and so on round the entire circle of magnets;
and by reason of the armatures R being hung or hinged, as described, the full power
of the magnet is available when the crank is at right angles to the armature and
magnet in operation.
The arrangement described is applicable to beam engines as well as to oscillatory
disc engines. The armature disc is thus caused to oscillate on its pivot and "wobble"
or roll. The motion thus obtained is by shaft and crank or other like contrivance
converted into rotary motion.

page_text: Having thus fully described my said Invention, and the manner of performing the
same, I wish it to be understood that I limit and confine my claims to,-
Firstly. The construction of magnets, as herein described; and illustrated by
Drawings.
Secondly. The hingeing or hanging the armature R, in manner and for the pur-
pose described and shewn.

In witness whereof, I, the said Michael Holroyd Smith, have hereunto set my
hand and seal, this Fourth day of April, in the year One thousand eight
hundred and seventy-eight.
