I WALTER MALTON BAYNES of Braganza, Torquay, in the County of Devon,
Gentleman, do hereby declare the nature of this invention to bo as follows:-
My invention refers to "carriers" for magic lantern slides and the like and consists
of a framework of rectangular or other convenient shape provided with grooves or clips
for holding the slide.
In order to hold slides of different lengths centrally I mount two suitably guided
sliding pieces in or on the frame. The sliding pieces have at their upper or lower
ends internal screw threads into which take the screwed ends of a rod or rods
mounted in suitable bearings in such manner that on turning a handle or knob
connected or fixed to the said rod or rods the sliding pieces will simultaneously and
at the same speed approach to or recede from each other and hold the slide
central or release same respectively. The sliding pieces may be grooved for holding
the slide more securely.
This slide carrier may be made partly of wood and partly of metal or wholly
of metal.
This carrier may also be used for other lens apparatus and in cases where it
is necessary to hold the slide centrally in a vertical as well as horizontal direction
another set of sliding pieces may be arranged to work independently or in connection
with those described above.

Improvements in Carriers for Magic Lantern Slides and the like.
I, WALTER MALTON BAYNES, of Braganza, Torquay, in the County of Devon,
Gentleman, 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 tho
following statement :-
My invention refers to carriers for magic lautern slides and the like and the said
carrier consists of a framework of rectangular or other convenient shape provided
with grooves or clips for holding the slide. This carrier or framework in order
that it may hold slides of different lengths centrally I make in the form of two
suitably guided sliding pieces mounted in or on the frame and provide them at their
upper or lower ends with internal screw threads into which take the screwed onds of
a rod or rods mounted in suitable bearings in such manner that on turning a handle
or knob connected or fixed to the said rod or rods the sliding pieces will simultaneously
and at the same speed approach to or recede from each other and hold the slide
central or release same respectively. The sliding pieces may be grooved for holding
the slide more securely.
This slide carrier may be made partly of wood and partly of metal or wholly of
metal.
This carrier may also be used for other lens apparatus and in cases where it is
necessary to hold the slide centrally in a vertical as well as horizontal direction
another set of sliding pieces may be arranged to work independently or in connection
with those described above.
In the accompanying drawing I have shown a magic lantern slide carrier constructed
according to my invention Figure 1 being a front view Figure 2 a vertical cross
section on line a a and Figure 3 a plan of underside or edge and Figure 4'a plan of
topside or edge.
-
A is the frame of rectangular shape provided with an upper and lower slot groove a
and a respectively for the reception and guiding of the slide carrier which consists of
two sliding pieces B and C. These sliding pieces have at their lower ends internal
screw threads viz. right hand thread in one and left hand thread in the other into
which take the screwed onds of a rod D mounted in suitable bearings d d d in such
manner that on turning the knob E fixed to the said rod the sliding pieces B and C
will simultaneously and at the same speed approach to or recede from each other and
hold the slide central between. them or release the slide respectively, and while
accommodating themselves to slides of different widths. The sliding pieces B and C
have vertical grooves for holding the slide. The nuts are by preference of metal
and have a tail piece let into the wood of the pieces B and C or these pieces may be
made entirely of metal. The top of the frame A has a slot for entering the slide
through as shown in Figure 4.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that I claim-
First A slide carrier for magic lanterns and the like consisting of two parts or.
pieces for holding the slide between them and which by means of right and left
hand screw or screws can be adjusted as to distance to suit various sizes of
slide the latter being always kept central in the frame or holder substantially as
set forth.
Second A slide carrier for magic lanterns and the like consisting of two parts B
and C which are guided in the frame A and can be adjusted by a right and left hand
screw spindle D substantially as described and shown.
