page_text: I ARTHUR PHILLIPS Jun. of 86 Bloom Street, Manchester in the County of
Lancaster Slide Colourist do hereby declare the nature of this Invention to be as
follows:-
My said Invention relates to the carriers which are used in magic lanterns to
exhibit the glass picture slides between the light and the lens as is well understood.
My improved carrier is made in two parts namely the carrier proper into which
the glass slides are placed and a frame in which the said carrier is capable of being
slid backwards and forwards. The carrier frame is introduced behind the lens in
the ordinary manner and is adjusted in position by a moveable stop or by other
means. The said frame is formed with grooves in which the carrier slides. The
carrier is also formed with grooves to receive and retain the glass slides which in
my improved carrier are dropped in through a slot from above, vertical guides
being provided to guide the slide into the lower groove of the carrier. As these
glass slides are sometimes of different lengths I attach a device to the carrier
frame for automatically centering the picture with relation to the lens. The said
device consists of an arm or lever pivotted centrally with regard to its length at
one end of the carrier frame and swinging loosely on its pivot. The bar carries at
one end a projection which is intended to come against the end of the glass slide
while at the other end is another longer projection which comes into contact with a
stop bar extending across the slide carrier. The action of the lever is as follows-
Supposing the slide carrier to be drawn out and a glass slide introduced the carrier
is pushed forward until the said cross stop bar on the carrier comes into contact
with the longest projection on the pivotted lever pushing it forward and causing
the lever to turn on its pivot until the opposite end of the lever meets the
advancing glass slide. As both ends of the lever are thus blocked between the
cross stop bar and the end of the slide, further advance of the slide and carrier is
prevented and if the pivot of the lever is properly situated with relation to the
aperture in the carrier frame it will be found that the centre of the slide is exactly
opposite to the centre of the aperture the same result being obtained with slides
of varying lengths. Instead of using separate masks of different shapes for the

carrier frame aperture I employ a sliding plate or mask in connection with the
carrier frame the said mask plate having apertures of different shapes. For
example such a mask plate might have both a round and square or "Cushion
aperture so that when it is desired to alter the mask from one shape to the other
the plate would be slid across the carrier frame aperture so as to bring the required.
shape of mask aperture into position. Stops are attached to the carrier frame so
as to limit the play of the said sliding mask and to ensure that the mask apertures
will be central with relation to the slides. The plate may be pushed in or
withdrawn by means of a projecting tail which can be grasped by the operator.

page_text: Improvements in Magic Lantern Slide Carriers and Fittings.
I ARTHUR PHILLIPS junior of 86 Bloom Street Princess Street Manchester in
the County of Lancaster Writer on Glass do hereby declare the nature of my
invention for IMPROVEMENTS IN MAGIO LANTERN SLIDE CARRIERS AND FITTINGS
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
My said invention relates to the carriers which are used in magic lanterns to
exhibit the glass picture slides between the light and the lens as is well understood.
My improved carrier is made in two principal parts namely the carrier proper,
into which the glass slides are placed, and a frame in which the said carrier is
capable of being slid backwards and forwards. The carrier frame is introduced
behind the lens in the ordinary manner and is adjusted in position by a movable
stop or other means.
The practical construction and application of my invention will be readily
understood on reference to the sheet of drawings hereunto annexed, and the
following explanation thereof.
Fig. 1. is a side elevation of the improved carrier frame with the carrier shown
in dotted lines. Fig. 2 is an elevation of the carrier detached. Fig. 3. is a vertical
section of the latter through about the line A. B in Fig. 2. the section of the carrier
frame being shown in dotted lines. Fig. 4 is a detached view of the mask plate,
and Fig. 5 is a horizontal section (through about the line C-D in Fig. 1.) of the
whole slide carrier and fittings complete.
The improved carrier frame a, a (Fig. 1.) is formed with internal grooves at top
and bottom (see dotted lines in Fig. 3.) in which the carrier b, b (Fig. 2) slides.
The slide carrier b, b (Fig. 2) is also formed with grooves to receive and retain
the glass slides o, c (dotted lines in Fig. 2.) which in my improved carrier are
dropped in through a slot from above, which is formed between the edge of the
carrier frame and the shoulder y of the carrier when the slide carrier b, b is drawn
out to a certain extent, vertical guides being provided to guide the glass slide c, c
into the lower groove of the carrier b, b. As these glass slides c, c are sometimes of
different lengths I attach a device to the carrier frame a, a (Fig. 1.) for auto-
matically centering the picture with relation to the lens.
The said device consists of an arm or lever d, d pivotted at e centrally with
regard to its length at one end of the carrier frame and swinging loosely upon its
pivot e. This lever d, d carries at one end a projection f which is intended to come
against the end or edge of the glass slide, whilst at the other end of the lever is a
corresponding projection g which comes into contact with a stop bar or pin h, h
attached to and extending wholly or partially across the slide carrier b, b.
The action of this lever d, d is as follows:-Supposing the slide carrier b, b to be
drawn out (to the right) and a glass slide c, o introduced, the carrier b, b is then
pushed forward (to the left) by the shoulder y of the slide carrier b, b until the
stop bar or pin h, h on the carrier b, b comes into contact with the lower pro-
jection g, g on the pivotted lever d, d, pushing it forward and causing the said
lever to turn on its pivot e until the projection f at the upper end of the lever d, d
meets the advancing glass slide c, c.

page_text: As both ends of the lever d, d are thus blocked between the stop bar or pin h, h
and the end or edge of the glass slide c, c, further advance of the slide and carrier
is prevented and if the pivot e of the lever d, d is properly situated with relation
to the aperture in the carrier frame a, a it will be found that the centre of the
slide c, c is exactly opposite to the centre of the aperture, the same result being
obtained with glass slides of varying widths.
Instead of using separate masks of different shapes to limit the aperture of the
carrier frame I employ a sliding plate or mask i, i (Fig. 4) in connection with the
carrier frame, the said mask plate having apertures of different shapes. For
example such a mask plate might have both a round and a square or cushion-
shaped aperture (as shown at Fig. 4) so that when it is desired to alter the mask
from one shape to the other the plate i, i would be slid across the carrier frame
aperture so as to bring the required shape of mask aperture as shown by the dotted
lines at Fig. 4.
A slot k, k (Fig. 1.) or other suitable stops must be provided in the carrier
frame a, a so as to limit the play of the said sliding mask i, i and to ensure that
the mask apertures will be central with relation to the slides.
A pin or stud 1, 7 fixed to the tail end of the plate i, i projects through the
carrier frame by means of which the mask plate can be moved backwards or
forwards by the operator as required.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 'I declare that what
I claim is :-
:-
First. The general construction and combination of the carrier frame, slide
carrier and fittings substantially as described and illustrated.
Secondly. I claim the construction and combination of the pivotted lever with
its two projections and the bar or pin attached to the slide carrier for centering the
glass slide substantially as described, and
Thirdly. I claim the construction and combination with the carrier frame of the
double mask plate substantially as and for the purposes described.
