PROVISIONAL SPECIFICATION.
Improvements in Mechanical Stages or Adjustable Object Holders
for Microscopes and Photo-microscopes.
I, FREDERICK ILES, Manufacturer of 100 Highgate Street, Birmingham, do
hereby declare the nature of this invention to be as follows:-
A moveable plate of metal, glass, or other suitable material, so adapted as to
hold the microscopic object glass or other subject under observation, is attached to
the fixed body or stage of the instrument by means of clips or springs, in such
manner as to permit the said plate to move firmly but freely over a sufficient
area.
To one end of the said plate is pivoted a simple lever working upon an axis or
pin attached to the fixed portion of the instrument and capable of being actuated,
by means of a milled head or handle, laterally.
The other end of the said plate is pivoted in a similar manner to a similar lever,
but with the intervention of a second lever between it and the axis or pin of the
actuating milled head or handle so that the motion imparted by it, to the plate, is
at right angles, or approximately so, to the motion produced by the lever at the
other extremity of the said plate.
The combined motions of the simple and compound levers permit of the plate
being moved over such area as will bring all parts of the object under observation,
opposite to the axial line or focus of the instrument.
In instruments where the stage or plate is at an inconvenient distance from the
observer, the axes of the actuating levers or handles are extended to such length
as to be conveniently manipulated by the observer.

COMPLETE SPECIFICATION.
Improvements in Mechanical Stages or Adjustable Object Holders
for Microscopes and Photo-microscopes.
I, FREDERICK ILES of 100 Highgate Street, Birmingham, Manufacturer 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:-
A moveable plate of metal, glass, or other suitable material, so adapted as to
hold the microscopic object slide or subject under observation, is attached to the
fixed body or stage plate of a microscope by means of clips or springs in such
manner as to permit the said plate to move freely over a sufficient portion of the
fixed stage.
To one end of the said moveable plate is pivoted a simple lever working upon an
axis or pin attached to the fixed portion or stand of the instrument and capable of
being actuated, by means of a milled head or handle, laterally in either direction.
The other end of the moveable plate is pivoted in a similar manner to a similar
lever, but with the intervention of a secondary lever or crank between it and the
axis or pin, attached to the other side of the fixed part of the instrument, carrying
a milled head or handle, so that the motion imparted by it to the moveable plate is
ונ..מ

page_text: at right angles or approximately so to that imparted by the simple lever at the
other extremity of the moveable plate.
By means of the one or the other of the milled heads or handles the moveable
plate can be moved either in a lateral or horizontal direction, or in a perpendicular
or up & down direction; or by working the milled heads or handles simultaneously,
the moveable plate can be projected in any required diagonal direction.
The levers pivoted to the moveable plate may themselves constitute the springs
necessary to hold the said plate in close contact with the fixed stage of the
instrument.
In instruments where the stage upon which the objects to be observed is at-a
distance from the observer, as in photo-microscopes, the axes of the actuating
levers are extended to such a length as to be conveniently manipulated by the
observer, by the milled heads or handles attached to their further ends.
In the accompanying drawing O represents the moveable plate carrying the
object slide between the grips G G, the plate O can move freely over the
bearers B B attached to the microscope stage S, and is actuated by the handles H¹
& H', working upon the axes X X, through the medium of the levers L' and. L'
and link E; the handle H' imparting a lateral motion and the handle H* imparting
a perpendicular or up and down motion.
The levers L' and L' are pivoted at P P to the moveable plate O and the
lever L is pivoted at P' to the link E.
M represents the point of attachment to the microscope body.
The handles H and H2 may be replaced by milled heads if more convenient, and
the axes X X may be extended to any desired length when necessary and the
handles or milled heads attached to their further extremities.
A is the aperture in moveable plate and corresponds with a similar aperture in
stage S.
RR are rest pins for keeping object slide in position.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :
1stly. A mechanical stage or object holder for microscopes and photo-microscopes,
having a moveable plate, upon which the object to be viewed or examined is placed,
which said plate is actuated at one of its extremities by a simple lever so as to
impart to it a lateral or side to side motion, and actuated at the other extremity
by a compound or duplex lever so as to impart to it, i.e. the said plate, a movement,
at right angles or approximately so, to that imparted by the simple lever
aforesaid.
2ndly. The extension of the axes or pivots of the aforesaid simple and compound
levers, so that motion may be communicated to the said levers from any desirable
distance.
