A Combined Kinematograph and Magic Lantern.
We, ALVAN CURTIS ROEBUCK, Manufacturer, and FRANK MCMILLAN, Manu-
facturer, both of 56, Fifth Avenue, the City of Chicago, in the County of Cook, and
State of Illinois, United States of America, do hereby declare the nature of
this invention to be as follows:-
-
The present invention relates to improvements in combined Kinematographic
apparatus, and magic lantern so arranged to be readily interchangeable, in
order that in giving a public exhibition, an ordinary lantern slide can be dis-
played during the interval in which the change in the Kinematographic apparatus
irom one set of moving pictures to another, is being made.
The present improvement has for its object to provide a simple and effective
arrangement and combination of parts, with which the change above described
can be effected in a ready and convenient manner.
The objective of an ordinary magic lantern is hinged at one side by a hinge
to the stationary front head of the magic lantern, so as to be capable to be swung
to one side when desired and for the purpose hereinafter stated.
The condenser slide receiving way or passage slide and bellows connections
of the magic lantern will be of the usual and ordinary construction, and adapted to
be adjusted to and from the front head upon the usual horizontal track rods.
The Kinematographic apparatus can be of any usual and suitable construction.
In the present improvement a transversely arranged horizontal track or rod,
is secured at each end to the front head of the magic lantern, by a bracket frame
a short distance above the ground line.
A head is arranged which can slide upon the track rail or rod and is formed
with a vertical socket to receive the lower end of the vertical stem of the Kine-
matographic apparatus which is adjustably secured in place by a set screw at the
side of such socket.
A second socket is arranged on the sliding head and arranged in front of the
main socket and formed with a vertical screw threaded bore, to receive a similarly
formed shank or bolt the head of which is adapted to rest upon the surface of
the table top or other like support, and by its vertical adjustment in the second
socket to effect a proper alignment of the Kinematographic apparatus and bring
its focal axis in line with the focal axis of the main lantern and the condensor
thereof.
In use, when it is desired to use the Kinematographic apparatus to give a
display of moving pictures, the ordinary magic lantern objective will be swung
out of the way, on its hinge and the Kinematographic apparatus moved laterally
upon the track to bring its focal axis in line with that of the main lantern and
condensor.
With the ending of the display of the one series of moving pictures, the Kine-
matographic apparatus, can be moved laterally to one side of the focal axis of the
main lantern portion of the apparatus and entirely out of the path of the same
after which the magic lantern objective can be swung back into place and an

page_text: ordinary lantern slide be introduced into the slideway or passage to give a
stationary picture exhibition, whilst the Kinematographic apparatus is being
changed from one series of moving pictures to another.

We, ALVA CURTIS ROEBUCK, Manufacturer, and FRANK MCMILLAN, Manu-
facturer, both of 56, Fifth Avenue, City of Chicago, in the County of Cook, and
State of Illinois, United States of America, 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:-
The present invention relates to a combined Kinematograph and magic lantern,
and is so arranged as to be readily interchangeable, in order that in giving a
public exhibition, an ordinary lantern slide can be displayed during the interval
in which the change in the Kinematograph apparatus from one set of moving
pictures to another is being made.
The present improvement has for its object to provide a simple and effective
arrangement and combination of parts with which the change above described
can be effected in a ready and convenient manner.
We attain such object by the mechanism illustrated in the accompanying
drawings, in which:
Figure 1, is a perspective view of the present apparatus, with the Kinemato-
graph portion thereot in position for use, and with the magic lantern portion in
a position of non-use.
Fig. 2, a plan view of the apparatus, illustrating a reversed arrangement of the
parts to that shown in Fig. 1, in full lines, and the same arrangement in dotted
¡ines.
Figure 3, a detail horizontal section, illustrating the slide etc., on which the
Kinematograph portion of the apparatus is supported.
Similar numerals of reference indicate like parts in the different views.
Referring to the drawings:
1, represents the objective of an ordinary magic-lantern which objective in
the present improvement is hinged at one side by a hinge 2, to the stationary
front head 3, of the magic lantern so as to be capable to be swung to one side
when desired and for the purpose hereinafter stated.
The condenser 4, slide receiving way or passage slide 5, and bellows con-
nections 6, of the magic lantern will be of the usual and ordinary construction,
and adapted to be adjusted to and from the front head 3, upon the usual horizontal
track rods 7.
8 is the Kinematographic apparatus of any usual and suitable construction.
In the construction shown in the present drawings 9 is the body portion of
such Kinematographic apparatus 10 the objective thereof, and 11 the vertical
stem by which the apparatus is supported.
In the present improvement 12, is a transversely arranged horizontal track
rail or rod, secured at each end to the front head 3, of the magic lantern, by
bracket frame 13, a short distance above the ground line, as shown.
14, is a head sliding upon the track rail or rod 12, and formed with a vertical
socket 15 to receive the lower end of the vertical stem 11 of the Kinematographic

page_text: apparatus 8 which is adjustably secured in place by the set screw 16, at the
side of such socket 15, as shown.
17 is another socket on the sliding head 14, arranged in front of the main
socket 15 and formed with a vertical screw threaded bore, to receive the similarly
formed shank of bolt 18, the head 19, of which is adapted to rest upon the surface
of the table top or other like support, and by its vertical adjustment in the
socket 17 to affect a proper alignment of the Kinematographic apparatus and
bring its focal axis in line with the focal axis of the main lantern and the con-
denser thereof.
In use, when it is desired to use the Kinematographic apparatus S to give a
display of moving pictures the ordinary magic lantern objective 1 will be swung
out of the way on its hinge 2 in manner indicated in Fig. 2 and the apparatus 8
moved laterally upon the track 12, to bring its focal axis in line with that of
the magic lantern and condenser.
the same
With the ending of the display of the one series of moving pictures, the
Kinematographic apparatus can be moved laterally to one side of the focal axis
of the main lantern portion of the apparatus and entirely out of the path of
as illustrated in Fig. 2 after which the magic lantern objec-
tive 1. can be swung back again into place and an ordinary lan-
tern slide be introduced into the slideway or passage 5 to give a stationary
picture exhibition while the Kinematographic apparatus is being changed from
one series of moving pictures to another.
Having new particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is:
1. The combination of a magic lantern having a removable objective, a
Kinematographic apparatus, a laterally movable head carrying said Kinemato-
graphic apparatus and means for guiding said head in its lateral movement, sub-
stantially as set forth.
2. The combination of a magic lantern having a removable objective, a Kine-
matographic apparatus, a laterally movable head carrying said Kinematographic
