Improvements in or relating to fhotographic Cameras,
A communication from WILLIAM BRUNS of 492 Lasalle Avenue, Chicago, Illinois,
United States of America, at present residing at London, England.
1, ALFRED JULIUS BOULT of 111 Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to improvement in photographic cameras and is more
especially applicable to that class of such instruments, known as "hand" cameras
of the magazine type; and it consists in certain peculiarities of the construction,
novel arrangement and operation of the various parts or elements thereof, as will
be hereinafter more fully set forth.
The principal objects of this invention, are, to provide a light, portable and com-
pact camera in which a plate-carrier and a mechanism to operate the same are
located, whereby a number of sensitized plates or films may be successively brought
or placed into the focal plane, or into position for exposure to the light when
desired, by the inward movement of one of the telescopic sections comprising
the casing, and successively released from the carrier and deposited by the with-
drawal or outward movement of said sections; to furnish a construction by means
of which the plates, after they have been placed in the carrier, may be manipu-
lated without opening the casing or without the employment of exterior or pro-
truding devices, such as levers, thumb-buttons or screws and the like Another
object of this invention is to afford a camera comprising a mechanism to perform
the above named operations, the parts of which to a great extent, when so desired,
may be stamped out of sheet material, thereby not only reducing the weight and
size but materially simplifying and cheapening the construction.
Other objects
and advantages will appear in the following description.
Figure 1 is a perspective view of the camera, showing it in its compact and
portable form, or its parts in their retracted position.
Figure 2 is a similar view illustrating the sections composing the casing in
their extended positions.
Figure 3 is an enlarged longitudinal sectional view of the camera, taken on
line 3, 3, of Figure 4, showing the parts in the position they will occupy when
ready for an exposure.
Figure 4 is a cross sectional view, taken on line 4, 4, of Figure 3. And
Figure 5 is a central longitudinal sectional view, showing the sections of the
casing and the parts of the camera in their extended positions.
A represents the outer casing of the camera, and consists of a rectangular box
open at one of its ends to receive the inner casing B, which two portions are
adapted to telescope one with the other, and are preferably made of sheet metal,
each having at its outer end a removable cap a, and a¹, of similar material,
which are preferably secured on their respective casings by means of depressions a²,

page_text: and corresponding protuberances a³, formed by means of a suitable punch or other
instrument. In the front portion of the casing A, is vertically located a parti-
tion a, which is provided with an opening a, for the reception and retention
of a suitable lense, (not shown). Secured to the inner or rear surface of the
partition a, is a rectangular dark box C, which has its rear end open and th
perimeter of said end preferably for..d with internal flanges c. to closely fit
within the rectangular frame C, composing a part of the magazine or plate-
carrier, and against the flanges d, of the plate-holders, thereby forming a light
tight connection or contact. The magazine or plate-carrier comprises the
frame C, which consists of three sides of a rectangular figure, and is pivotally
secured by means of pins c¹, near its open end to the inner casing B, and a box C³,
which is pivotally secured at its lower end by means of rivets, to the lower or
open end of the frame C, and is adapted to fit snugly and be retained within said
casing, by reason of frictional contact therewith. The rear outer surface of the
box C, is provided near its upper end with a projection ³, for the convenience
of removing the box from the frame C, when desired to insert the plate-holders.
The front portion of the box C2, or that portion thereof adjacent to the box C, is
open and its sides are formed in their upper parts with slots c, and upwardly
extending projections to receive and engage respectively, the lateral projec-
tions d, on the plate-holders D, which holders are made of rectangular pieces of
sheet material and have three of their edges bent to form flanges d, to receive the
sensitized plates D¹. Secured to the inner rear surface of the box C, are a
number of springs e, which have a tendency to press the plate-holders D, forwardly
through the open portion of said box. The lower end of the box C², is provided
with inwardly projecting lugs c7, located thereon near the sides and edge of the
opening in the box and prevent at said end the outward displacement of the
plate-holders, which would otherwise be caused, by reason of the pressure of the
spring, there-against. The lower end 3, of the box C, has secured thereto,
by means of a torsion spring 8, a discharger or releaser E, for the plate-holders,
which is substantially rectangular in cross-section, and has one or more rear-
wardly extending flanges e, to contact with the cap a¹, or end-piece of the inner
casing B, for the purpose as will be presently explained.
The lower or inner portion of the discharger E, is provided with an arm e',
which extends inwardly and about at a right angle to the body of the discharger,
through a slot or opening in the lower, edge of the lower end-piece C³, of the
box C, which contains the plate-holders. The lower surface of the inner
casing B, is formed or provided internally near its inner end with projections f,
to prevent the plate-holders after they have been released from the carrier, sliding
forward, and the cap a', is also provided on its inner surface with similar projec-
tions, to guide the, plate-holders forward, as they drop from the carrier. "On
each side of the frame C, and near its upper portion, is pivotally secured
one end of a lever G, whose other, end is. likewise secured on a
pin g, located in
the front part of the outer casing. Each of the sides of the inner casing or
section B, is formed or provided internally with a bracket h, on which the sides
of the frame C, may rest, when the casings are in their extended position.
In Figures 1 and 2 of the drawing, the outer casing A is shown, provided
with a combined finder and handle, which consists of ja tube 3, which may be
rigidly secured on the casing,..by means of standards h¹; as shown in Figure 1
of the drawing, or said standards may be secured to the casing, by means of a
hinge 3, as shown in Figure 2, in which latter construction it is evident that
the finder may be turned on its hinge to lie closely against the casing.
The operation is as follows:
17
The cap or end-piece a, of, the casing. B, may be removed, while the casing is
in its contracted position, as shown in Figure 3 of the drawing, when the plate-
carrier will be in a vertical position, as shown in said figure. The box or maga-
zine C, may then be turned outwardly on its pivots 3, on the frame C¹, and the
plate-holders placed and secured therein, by pressing down the springs 6, and
A

page_text: forcing the forward ends of the holders under the lugs c, and the arms or pro-
jections of the plate-holders under the projections, of the plate-holding box.
When a sufficient number of plate-holders shall have thus been placed within the
box,, it may be returned to its vertical position within the frame C, and there
held by, frictional contact or otherwise. By withdrawing or extending the
casing B, to the position shown in Figure 2 of the drawing, the frame C¹, carry-
ing the box or magazine C², will be tilted or turned on its pivots c¹, by reason of
the levers G, connected to its upper end, in which operation the flanges e, of the
discharger or releaser E, will impinge the cap a¹, of the inner casing B, which
will force the projection e¹, of the discharger or releaser against the end of the
lower plate-holder, and cause it to be moved forwardly, until the projections or
arms d', on its front end will be released from the projections 5, of the box, thus
causing the plate-holder to be deposited in the bottom of the inner casing, the
remaining plate-holders will be retained, by reason of the engagement of their
arms d, wih the projections 5, of the box. By again pushing in the inner
casing, the plate-carrier will be raised to a vertical position at the inner end of
the box C, ready for another exposure.
Having now particularly described and ascertained the nature of the said in-
vention, as communicated to me by my foreign correspondent, and in what manner
the same is to be performed," I declare that what I claim is:-
