I, CHARLES HARRIS SHAW, of 637, Putnam Avenue, Borough of Brooklyn, City
of New York, State of New York, United States of America, Jeweller, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:—
My invention relates to cameras, and more particularly to that class of cameras
known as "panoramic cameras.
"
I will describe a camera embodying my invention and then point out the novel
features in the claims.
In the accompanying drawings, Figure 1 is a horizontal sectional view of a
camera embodying my invention. Fig. 2 is a vertical sectional view of the
casing and showing a rear elevation of the camera parts. Fig. 3 is a vertical
sectional view. Fig. 4 is a detail cross-sectional view of a lens-cylinder and a
light-shaft. Fig. 5 is a perspective view of the camera.
Similar letters of reference refer to corresponding parts in all of the figures.
A represents a suitable casing for containing the several parts of the camera.
One of its walls-as, for instance, the wall A is detachable from the remainder
of the casing, and it is to this wall that I connect two plates, between which
plates several parts of the camera mechanism are located and held. This arrange-
ment permits of the working parts of the camera being removed from the casing
for examination and the substituting of one film for another.
B 1 represents the two plates that are connected to the wall A¹ and which
extend outwardly therefrom. These plates are detachably connected to protrud-
ing parts a of the wall A. The parts a may be integral with the wall A¹ or
separate therefrom, in which case they are held by screws a¹. Between the two
plates B B and at the sides thereof I locate walls b. These walls may be sup-
ported by standards 61, to which they are secured, and the standards may be held
at their ends between the two plates. These standards also serve to support the
plates B B and to space them apart. The purpose of these walls bis to exclude
light from that part of the film not within the path of movement of a light-shaft
that is employed in the camera.

page_text: C, represents a cylinder placed vertically in an opening provided in the wall A'.
It is preferably arranged to have a portion projecting beyond the outer surface
of the wall A. It is arranged to oscillate in the opening on journals that are
provided in the ends of the cylinder. These journals may conveniently consist
of circular plates c, that fit in the ends of the cylinder C. These plates may
be carried by the plates B and B', being secured thereto by any desired means---
as, for example, by solder. The cylinder is provided with an opening c¹ in that
portion of its wall projecting beyond the wall A; and diametrically opposite this
opening is a second opening, into which one end of the light-shaft is secured.
The light-shaft is preferably rectangular in cross-section and is adapted to move
with the cylinder, and it is of such a length as to have its free end move in
a plane that is parallel with and adjacent the film or other sensitized surface used
in the camera.

"
represents a lens that is carried by a suitable holder c. The holder c¹ is
inserted in an opening provided in a wood or other block 5, that is held within
the cylinder C. The lens is placed in the line of the openings in the cylinder C,
so as to project the light-rays through the light-shaft on to the sensitized sur-
face. When the cylinder C, carrying the lens, is oscillated with the lens exposed,
the light-rays from the different parts of the view being photographed will be
projected by the lens through the light-shaft onto successive portions of the film
or plate in the camera as the light-shaft is moved in front thereof. The cylinder
may be oscillated in one direction by means of a coiled spring c, that is prefer-
ably located within the cylinder. One end of the spring is secured to a stationary
part as, for example, to a pin c, carried by one of the plates while the other
end of the spring may be secured to the cylinder. The cylinder and light-shaft
may be moved in the other and opposite direction for the purpose of "setting
the lens, and light-shaft by hand. When the cylinder is moved in this direction,
the spring is placed under tension to move the cylinder and light-shaft in the
first-mentioned direction-that is, in the direction to expose the film. It is
cbvious that the speed of the lens-cylinder and light-shaft may be regulated by
changing the tension of the spring. The joint made by the wall of the cylinder
and the walls of the opening in the part A', in which the cylinder is placed,
may be made light-proof in any convenient manner, as by felt co or metal, which
would conform to the wall of the cylinder. Any desired means may be employed
for holding the light-shaft and cylinder in “ set" position and for releasing them
from set position. I have shown in the drawings, the following arrangement of
parts for doing this. A lever D is pivoted to the upper plate B, so as to have
one of its ends d in the path of movement of the light-shaft. As the light-shaft
is moved to set position this end d will be made to engage with the light-shaft to
hold it against the action of the spring co. A flat spring d is preferably pro-
vided for holding the end d in the path of movement of the light-shaft. The
other end d² of the lever is so arranged as to be engaged by a button d³, carried
by the casing A, which when depressed to engage the end 2 causes the end d
to move out of engagement with the light-shaft. A shutter may be provided in
the cylinder to cover the lens when desired, a knob or projection being pro-
vided for moving it over the lens after the film has been exposed and the cylinder
and light-shaft are to be reset. This knob or projection may also be used to
move the cylinder and light-shaft to set position.
EE represent shutters which are provided for the end of the light-shaft. One
of the shutters is provided for closing the end of the light-shaft when the camera
is in set position, while the other shutter is for closing the end of the light-shaft
after it has been released from set position and it has moved in front of the film
to expose it. With this arrangement of the shutters for the end of the light-shaft
all light-rays from the lens are excluded from the camera while the light-shaft
is at rest. These shutters are operated automatically and preferably by the
light-shaft coming into engagement with them. Each shutter may conveniently
consist of an L-shaped piece of metal that is provided with a pivot e at each

page_text: end, which pivots have a bearing in the plates B and B. A spring e² is pro-
vided for each shutter for the purpose of holding it in such position as to be
operated by the light-shaft. These springs are preferably flat ones, and they are
secured at one of their ends to the walls b. The operation of these shutters is
as follows: When the light-shaft and cylinder are moved to set position, the
light-shaft engages with one arm 3 of the shutter, against which the spring e
bears, and moves it against the action of the spring so as to bring the other
arm e of the shutter over the open end of the light-shaft to completely close it.
When the light-shaft is released to expose the film, the end of the light-shaft
moves away from the arm e to throw the light-rays onto the film. As it moves
in front of the film it comes into engagement with the arm e of the shutter E¹
and moves this arm to cause the arm e¹ of this shutter to completely close the
end of the light-shaft, and thus prevent any more light-rays entering the interior
of the camera. The shutter is then moved over the lens and the cylinder and
light-shaft reset for another exposure. After the cylinder and light-shaft have
been reset the shutter is moved from in front of the lens, thus having the
camera ready for another exposure. It will be seen, therefore, that the purpose
of the shutter is merely to cover the lens while the camera is being reset and
also to protect the lens from dust, etc., when not in use.
A film is preferably used in the camera and provision is made for inserting in
the camera the spool, on which the film is generally wound, and unwinding the
film from the spool as it is needed onto a second spool. F represents the spool
carrying the film f, and F the spool onto which the film is wound. The spool Fi
is provided with the usual ratchet and the pawl engaging therewith, and this
spool is turned by the usual key f2, carried by the casing A.
The rollers F and F are removably held in spring-pieces f³ that may be
secured to the plates B and B on the outside thereof by rivets, which rivets are
located at the middle of the pieces. These pieces are near the wall A¹ of the
casing, so that the spools will be in the position shown in the drawings. The
film from the spool F is passed over a roller f, journaled in the plates B B', and
preferably against curved flanges f, that are carried by the said plates, and over
a roller f to the spool F. Guide-rods fmay also be provided to prevent the film
moving away from the flanges while being transferred from one spool to the
other. The usual opening A³ and its colored covering A are provided in the
casing A in order that the position of an unexposed part of the film may be
gaged through the usual marks or signs provided on the backing of the film.
