PROVISIONAL SPECIFICATION.
Improvements in connection with the Use of Kinetoscopes.
I, CHARLFS RALEIGH, of 58, Chancery Lane, in the County of Middlesex,
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to apparatus for photographically recording representa-
tions of moving objects and for phonographically recording the sounds which
accompany such movements The apparatus 18 also designed for simul-
taneously reproducing the said movements and the corresponding sounds
In carrying out my invention, the representations of moving objects are
recorded and reproduced on the now well known kinetoscopic principle, the
accompanying sounds being recorded by means of a phonograph and reproduced
in exact unison with the reproduction of the representations
The combined apparatus is preferably provided with sight holes and ear
trumpets, arranged in such a manner that when the eyes of the user are opposite
the sight holes, his ears are in juxtaposition to trumpet-mouthed tubes which
convey the sound from the phonograph, the kinetoscopic portion of the apparatus
being connected by suitable gearing with the phonographic portion; so that, in
the event of any variation occurring in the speed at which the apparatus is
worked, both portions are equally affected.
The sound effects may, in suitable cases (as for example a representation of
soldiers marching), be produced by such means as are employed in the ordinary
barrel organ or musical box; the latter being geared to work in unison with
the kinetoscopic apparatus. Means may be employed to increase or diminish
the volume of sound as the representation appears to approach or recede from the
spectator

page_text: manner the same 18 to be performed to be particularly described and ascertained
in and by the following statement:-
This invention relates to apparatus for displaying pictorial representations
of moving objects and for simultaneously reproducing the sounds which accom-
pany the movements.
In carrying out my invention, the representations of moving objects are
recorded on the now well-known kinetoscopic principle, the movements and the
accompanying sounds being subsequently reproduced in exact unison.
A combined apparatus adapted for accomplishing the object of my invention
16 preferably provided with sight-holes and ear-tiumpets, arranged in such a
manner that when the eyes of the user are opposite the sight-holes, his ears are
in juxtaposition to trumpet-mouthed tubes which convey the sound from the
phonograph; the kinetoscopic portion of the apparatus being connected by suitable
gearing with the phonographic portion, so that, in the event of any variation
occurring in the speed at which the apparatus is worked, both portions are equally
affected.
The sound effects may, in suitable cases (as for example, a representation of
soldiers marching) be produced by such means as are employed in the ordinary
barrel organ or musical box; the latter being geared to work in unison with the
Linetoscopic apparatus. Means may be employed to increase or diminish the
volume of sound as the representation appears to approach or recede from the
spectator.
In the accompanying drawings, I have illustrated the application of my inven-
tion to apparatus for displaying a series of pictures presenting the appearance
of animation and accompanied by appropriate musical, or other sounds, the
latter being, in the example illustrated, derived from a musical box. Fig. 1 18
a front view of the apparatus showing the relative positions of the eye-pieces or
sight-holes and the ear-trumpets Fig. 2 18 a view showing the positions of the
working-parts; one of the sound-passages, together with its ear-trumpet, being
in section. Fig 3 is a view similar to Fig. 2, but with the aural parts in eleva-
tion and with the pictures in position
The main shaft a is operated from the front of the machine by means of the
handle and train of spur-gear c. The reel or hub which carries the pictures is
mounted on a shaft d, arranged at right-angles to the shaft a and rotated by
means of bevel-gear e The barrel of a musical box f 18 connected with the main
shaft a by any suitable gear, such as a cord f1 and pulleys ff, whereby the
musical effects are rendered in unison with the pictorial representations. From
the musical box, a pipe or tube 9 leads to a chamber provided with a valve
or damper ¹ this damper being operated from the shaft d by an irregular
circumferential cam i and vibrating lover k. The function of the damper ¹ is
to regulate the volume of sound and bring it into harmony with the pictorial
representation in course of reproduction From the chamber h, the sound escapes
through a restricted pasage hs into a chest h³, which extends across the front of the
apparatus and passes thence, through the trumpet-mouthed tubes 4 h; these
ear-pieces serving to confine the sound to the ears of the listener
It will be obvious that the configuration of the cam may be varied at will
in order to produce the particular modulations of sound adapted to accompany
the particular series of movements pourtrayed
If the musical or other sound effects be produced with the aid of a phono-
graph, the sound-regulating device may be dispensed with
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I would have it
known that I make no claim to a mutoscope per se, but, I claim
1. The herein described means for reproducing a series of representations of
moving objects accompanied by appropriate sounds; same comprising a picture-

page_text: carrying reel or band and a phonograph or musical box arranged to work in
exact unison with the series of pictures, substantially as herein described.
2 In a combined visual and aural apparatus of the kind referred to in the
preceding claiming cause, the herein described means for modulating the sound
when a musical box is employed; such means comprising a cam, a vibrating lever,
and a damper arranged in the sound passage, substantially as set forth.
3 In apparatus for reproducing pictures of moving objects accompanied by
appropriate sounds, the employment of suitably disposed eye and ear-pieces
arranged substantially as herein described.
