PROVISIONAL SPECIFICATION left by the said Edward John Manwaring
at the Office of the Commissioners of Patents. with his Petition, on the
22nd March 1858.
I, EDWARD JOHN MANWARING. of Lee, in the County of Kent. Gentleman,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
APPLICABLE TO STEREOSCOPIC APPARATUS," in be as follows:-
This Invention consists in the application to or combination with a stereo-
scope or apparatus for exhibiting stereoscopic. photographic, or other similar.
views, of a system of rollers, whereby views placed upon flexible material may
be wound, unwound, and rewound in the same manner as cloth could be
wound around such rollers, so as to be brought up to and taken away from
sight by acting upon the said rollers, without the trouble of taking away each
separate view and putting another in its place by hand.
The foregoing is a description of the nature of the Invention. which may
probably be varied in its practical details.

an Invention for "IMPROVEMENTS APPLICABLE TO STEREOSCOPIC APPARATUS," upon
the condition (amongst others) that. I. the said Edward John Manwaring, my
executors or administrators. by an instrument in writing under my. or
their, or one of their hands and seals, should particularly describe and
. ascertain the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal Patent.
Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that T. the said Edward John Manwaring, do hereby
declare the nature of my said Invention, and in what manner the same is to
be performed. to be particularly described and ascertained in and by the
following statement:-
(I.) The nature of the said Invention consists in the application to or
combination with the stereoscope. or apparatus for exhibiting stereoscopic.
photographic, or other similar views, of a system of rollers, whereby views
produced or placed upon flexible material may be wound, unwound, and
rewound upon or from such rollers, so as to he brought up to and taken away
from sight by acting upon the said rollers, without the trouble of taking away
each separate view and putting another in its place, as heretofore practised.
(II.) Having described the nature of the said Invention, I now describe
in what manner the same is to be performed, wherein I shall refer to the
Drawing hereto annexed, as hereafter followeth :-

page_text: Fig. 1 is a front view of a box or case containing the apparatus above
mentioned, this being intended to be attached to the bottom of a stereoscope;
Fig. 2, one end of such box or case; Fig. 3. the other end thereof; Fig. 4,
back view of the box or case. exposing the rollers: Fig. 5. view of the ends
of the pulley wheels on the working rollers, as they appear when the end of
the box or case is removed. Fig. 6, view of pulley wheel marked F, one
such being fitted and rotating on an axle of each roller C and B; Fig. 7.
transverse vertical section shewing the whole system of rollers, with the endless
band of views thereon.
A denotes the box or case: B. top working roller; C, bottom working
roller: G, G, (see Fig. 7) guiding rollers for keeping the views flat; D is a
pulley or driving wheel, to the axle of which the knob or turning handle D*
is attached, whereby the pulley wheels F. F. on the axle of the roller B and
the roller C respectively are set in motion, inasmuch as the motion given to D
is communicated to the others by the driving cord or band E. which may be
of india-rubber or other suitable material. It will be seen by Fig. 6 that the
pulley F has the face which is toward the end of the roller recessed except at
In
the parts marked x. (the black part in the centre indicating the axis).
this recessed part is a catch piece 1. which is loosely secured by a pin; this
catch piece is pressed upon by a spring 2. by which arrangement the roller is
suffered to turn one way only (that is in the direction of the arrow's head).
by reason that there is a stud or projecting pin (3) on the end of the roller
(F), which comes against the face of the pulley. This spring catch arrange-
meni is reversed in position on each roller, so that the turning handle makes
one roller to roll off and the other roll on. I denotes a screw. which forms
the axis of one end of roller. working in a socket in that end of said roller:
it can be unscrewed by turning the knob attached, and thus the roller may he
unshipped. J denotes a similar. except that instead of a knob there is the
usual cross-cut screw head. There is acting upon the enlarged part. K of
the roller (B or C) a spring, which presses against the edge. It is evident
that by turning the handle the working rollers will he set in motion, and thus
the roll of flexible material, having the views thereon, will be wound off the
one roller on to the other, passing before the eye of the spectator, being kept.
flat by the guide rollers (G, G.). This box or case is attached to the bottom
of the stereoscopic apparatus, by means of the catches H. H, which catch into
the bottom part where the views are placed under the old system; but any
other convenient mode of attachment may be adopted.

page_text: Instead of a box or case the apparatus might consist of a framework,
securing together the whole system of rollers, &c.
Instead of the wheels being worked by cords or bands, they may be worked
by toothed wheels or any other mechanical equivalent.
Although the Drawing shows the apparatus so constructed that it may be
attached to the bottom of the stereoscope, yet it might be placed in a proper
position conjunctively with any suitable apparatus of a binocular character, and
so exhibit the views to the eye as they are brought up by turning the handle
aforesaid.
It is to be remarked that my Invention enables me to produce transparent
views, although not depicted on glass, as I have my views depicted on a
transparent textile or other material.
(III.) Having now described the nature of the said Invention, and in
what manner the same is to be performed. I declare that I claim the nature
whereof is set forth in the outset. (marked I.) of this my Specification thereof.
In witness whereof, I, the said Edward John Manwaring, have here-
unto set my hand and seal, this Twenty-first day of September, in
the year of our Lord One thousand eight hundred and fifty-eight.
Witness,
