page_text: I, CHARLES PERCY Corr, of Treasury Buildings, The Castle, Dublin, in the County
of Dublin, Civil Servant, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to provide a simple and inexpensive device for
projecting living pictures upon a screen or the like that. shall obviate the quivering
motion and sudden extinction of the view, usually observable in similar pictures
projected by machinery generally in use at the present time.
In carrying my invention into effect, I mount a limelight or other suitable lantern
on a base plate in any convenient manner, said lantern having the usual slide holder
removed and the projecting tube with its lenses mounted on a vertical rod or standard
fixed to the said base plate so that a space is left between said projecting tube and
the condenser on the said lantern. Mounted upon a horizontal axle carried by another
vertical rod or standard fixed to the base plate, or otherwise conveniently arranged, I
place a disc of metal, wood, or any suitable substance. This disc is capable of
revolving in a vertical plane and presenting in the space between the condenser and
the projecting tube a succession of views. These views carried on photo lantern or
other suitable slides, films, or the like, are fixed in a number of circular apertures of
suitable size cut in the said disc near its periphery.
By means of these slides, which may be coloured if desired, a living picture is
produced on the principle of the "Wheel of Life," each slide portraying a movement
a stage in advance of the previous one. After the last slide has been presented to
the lantern the picture may be repeated as often as desired by simply continuing to
revolve the disc. The said disc is caused to revolve by means of two grooved pulley-
wheels, the smaller of which is attached to said disc at the centre and revolves upon
the same axle with it, whilst the larger revolves upon a separate horizontal axle
mounted on a standard below said disc or in any other convenient position. These
pulleys are connected together by an endless band made of rubber or any other
suitable material, and the larger pulley may be actuated by hand, for which purpose
it may be provided with a suitable handle, or in any other suitable manner. The
speed of the disc carrying the said slides may be regulated as required by increasing
or decreasing the diameter of the larger pulley-wheel.

page_text: I, CHARLES PERCY COPP, of Treasury Buildings, The Castle, Dublin, in the County
of Dublin, Civil Servant, 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 :-

I will now proceed to more particularly describe my invention in connection with
the accompanying drawings in which the same letters of reference indicate like parts
in the various figures.
Fig. 1 shows a front elevation of my apparatus, and
Fig. 2 shows a side elevation of my apparatus.
The lime light or other suitable lantern a, fitted with a condenser d, is attached to
any suitable base b, by means of the legs or supports c. Attached to the top of a
leg or support c¹ (the lower end of which is also fixed to the base 6) is the projecting
tube t, which carries the usual lenses. Mounted centrally upon a horizontal axle h
fixed at the upper end of a vertical rod or standard c² and so as to be capable of
revolving thereon, is the disc d¹. Mounted also upon this axle h, concentrically with
the disc d and fixed thereto, is the pulley wheel w. Mounted so as to revolve upon
the horizontal axle h¹ situated near the lower end of the vertical rod or standard c²
is the pulley wheel w¹. This pulley wheel w¹ is furnished with a handle e by means of
which it may be revolved when required, and is connected by means of a band or the
like f, with the pulley w; these two pulley wheels w and w¹ being situated so as to

page_text: be capable of revolving in the same plane. The disc d' has a number of circular
apertures p formed at regular intervals near the periphery thereof.
These apertures carry suitable slides, films or the like bearing the necessary
successive views of the living picture to be projected.
of the
When it is required to project a picture the lantern is lit and the handle
pulley wheel w¹ rotated, rotary motion being thus imparted to the pulley w and the
disc d' carrying the films or the like. As the disc d' rotates the films or the like
carrying the successive views of the pictures, are thus presented in rapid succession
before the condenser d and between it and the projecting tube t, and the picture thus
thrown upon a suitable screen. When the film carrying the last view of the picture
has been reached, the picture may be repeated by merely continuing to rotate the
disc d', or a fresh set of films or the like may be placed on the apertures p for the
production of the fresh picture. It is obvious that the pulley w¹ may be turned
either by hand or by power and that the relative sizes of the pulley wheels w and w
may be varied in order to regulate the speed of the disc d¹.
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 what I
claim is
Apparatus for projecting living pictures consisting of a lantern such as a and
projecting tube such as t attached to any suitable base in such a way that there is a
free space between them across which can be passed in rapid succession a series or
succession of views (to produce a living picture) carried by a revolving dise such as d¹
operated and substantially as herein described and illustrated.
