PROVISIONAL SPECIFICATION.
Improvements in Means for Exhibiting Pictures, Photographs, and
the like.
I JOHN WILLIAMS 52 Cae'r chwarel Rachub near Bangor, Mechanic do hereby
declare the nature of this invention to be as follows:-
This invention is consisted chiefly in the introduction of a glass vial for holding
water. This vial I make use of and is placed at the end of a cylinder tube. The
vial is constructed of plain glass with the exception of the front side which is a lens.
At a relative distance to the cylinder is placed a frame inside which a slide carrier
frame is used. The interior side of the frame contains a window of faultless
transparent glass, behind and adjacent to which the photo or picture to be
exhibited is placed erect. At the exterior side of the frame are placed two
shutters for the convenience of changing the objects for exhibition after sliding.
Improvements in Means for Exhibiting Pictures, Photographs, and
the like.
I, JOHN WILLIAMS 52 Cae'r chwarel, Rachub, near Bangor, Mechanic 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
etatement:-
In Figs. 1. and 3. the perspective view of the invention is shewn in different
forms. In Fig. 2. the section of Fig. 1. is shewn. Fig. 4 the facial view of
vial D. and Fig. 5. the back face of the frame E.
The cylinder is constructed of two parts as shewn in A. A' Figs. 1 & 3. The
portion A is fixed to the stand-board I. and the portion A¹ to slide back and fore
within A. to regulate the light upon the object to view. If desirable this may be
constructed round (pipe shape) with the back end square shape to fit the square in
frame C. At the fore-end of the cylinder A. Figs. 1. 2. 3. and inside is fixed the
vial D. which is made up of two glass parts as shewn in B and B¹ Fig. 2. The
side B. of vial is flat and the side B' of a lense which is fixed to B. as shewn
in Fig. 2.
The top part of the vial has a port R. for the purpose of filling it with water.
After the vial is fitted to cylinder A. a front piece L. Figs. 1. 2. 3. is fixed to
secure the vial firmly
At a relative distance to the vial the frame C. Figs. 1. 2. 3. is introduced fixed
into the stand-board I. The frame C. acts to support frame E. within which plays
the side carrier frame F. on grooves P. Figs. 2 and 5.
As per Fig. 1. objects for view can be exhibited only, in lighted rooms, whether

page_text: the light be natural or artificial. To exbibit them in the dark the portion A¹ of
the cylinder must be slided until it comes in contact with frame C. as shewn
in Fig. 3. A small lamp is then hung outside the portion A of cylinder against
the window K. Fig. 3. to throw light upon the picture to be exhibited. To make
use of the slide carrier frame F. Figs. 2. & 5. shutters H. H' are introduced.
The shutters are hinged at O. Fig. 5. to the slide-carrier frame. The photo or
object for exhibition is placed on shutter H. which is then closed as H. The photo
is then face to face against a window G. fixed in the nearmost side of the slide
carrier frame. In Fig. 2. the window G. and the shutter H. containing the photo
is shewn closed and fronting the vial D.
To change the object for exhibition shutter H¹ now slided to the left end of
frame E. is opened to insert a fresh object, then, closed as before and slided to the
right, the shutters being opened alternately as fresh objects have to be exhibited.
The one shutter pushing the other out of position frame F moving also with
them. And when either is dropped open, it rests suspended over a leaf-
board J. Fig. 5. hinged to frame E. as shewn at Q. Fig. 5. The spring
hinges N. are introduced to support the picture within the shutters. The
knob M. Figs. 1 & 3. is for sliding the cylinder A'.
. When the machine is not made use of, the shutters are closed, the leaf-board
raised and all fixtures inserted through S. to the vacuum T. in stand frame Fig. 2.
Having now particularly defined the several parts of this invention, I declare
what I claim is―
1. The construction of the cylinder to regulate the light, together with the
window K. and the front board L. as above described and delineated in Figs. 1. & 3.
in drawings.
2. Connected therewith the vial D. containing port R. described and delineated
in Figs. 1 to 4 of drawings.
3. Frames C. and E. containing the slide carrier frame and leaf-board J.
4. Connected with the slide carrier frame, the window G. shutters H. H' together
with the springs N. as described and delineated in Figs. 2. & 5. in drawings.
5. The invention as consisting of and connecting the several parts intact, for the
purpose already described and delineated by drawings.
Dated this 16th day of November 1896.
JOHN WILLIAMS.
