We ARTHUR RAYMENT of the firm of Perken Son & Rayment of 99. Hatton
Garden in the City of London Manufacturing Opticians. and GEORGE LYONB of
19 Somerset Street Portman Square London in the County of Middlesex
Gentleman do hereby declare the nature of this invention to be as follows.:
This invention relates to improvements in the ordinary photographic camera
which is made to fold up and lay closely together so as to pack away, easily and
only occupy a small space such camera being usually mounted upon a tripod stand
as is well understood."
Our present improvements consist in so constructing arranging and mounting the
"front
or part carrying the lens that such front can be readily and entirely
detached from the base board so as to be easily folded up and also can be readily
attached in the desired position on the base board when setting up the camera for
use thus greatly expediting the operation.

For this purpose we arrange a hinge pin or hinge pins on the lower part of-the
detachable "front and these pins (or pin) engage in eyelets or holes corre-
spondingly formed to receive them in or on the base board.
This hinge joint may be of any suitable character (and the parts when thus
hinged together may be kept in the desired position by means of any suitable spring
or springs or other equivalent appliance) for instance the joint may be made after
the manner of the well known bayonet joint.

Furthermore the front may be supported by an adjustable "strut
both sides thereof and the "front" being movable backwards or forwards (out of
the vertical line if desired) upon its hinge joint can be firmly fixed in any desired
position by the said adjusting struts and the back being also adjustable as usual our
present improvements thus afford increased facility in operating with the camera as
well as in speed in setting up and folding and effects considerable economy of the
space occupied by the folded camera as by our present improvements we are
thereby enabled' to make such.camera very compact..
A spring bolt or spring bolts may be arranged and mounted on the detachable
front to engage with corresponding eyelets or slots in or on the base board (or vice
versa) formed to receive said bolts such as in a similar manner to an ordinary door
latch Such bolts being thus self engaging and the slots etcetera to receive same
may be arranged in two or more separate positions so as to readily set up the front
at a greater or less distance from the focussing screen as desired.

Improvements in Photographic Cameras.
We, ARTHUR RAYMENT of the firm of Perken Son & Rayment of 99, Hatton
Garden in the City of London, Manufacturing Opticians, and GEORGE LYONS of
19 Somerset Street, Portman Square, London in the County of Middlesex,
Gentleman, do hereby declare the nature of this invention and in what manner

page_text: the same is to be performed to be particularly described and ascertained in and
by the following statement :-
This invention relates to improvements in photographic cameras of the ordinary
"bellows" type which is made to fold up and lay closely together so as to pack
away easily and only occupy a small space such camera being usually mounted upon
a tripod stand as is well understood.
Our present improvements consist in so constructing arranging and mounting the
"front
or part carrying the lens that such front can be readily and entirely
detached from the base board so that the camera can be quickly and easily folded
up and also the loose front can be readily attached in the desired position on the
base board when setting up the camera for use thus greatly expediting the
operation.
And in order to fully explain this invention we will proceed to describe same with
reference to the accompanying sheet of drawings.

DESCRIPTION OF THE DRAWINGS.
Figure 1. is a side view of a camera "set up "ready for use at short focus-such
camera having our present improvements applied thereto and showing in dotted
lines the camera as extended to its full length.
Figure 2. is an end view of the "front of the camera.
We arrange a hinge pin or hinge pins a on the lower part of the detachable
"front" and these pins a (or pin) engage in eyelets or holes at c correspondingly
formed to receive them in or on the base board d.
The hinge joint may be of any other suitable character (and the parts when thus
hinged together may be kept in the desired position by means of any suitable spring
or springs or other equivalent appliance) for instance the joint may be made after
the manner of the well-known bayonet joiut.
Further the front may be supported by an adjustable stiut fon one or both sides
thereof and the "front" being movable backwards or forwards (out of the vertical
line if desired) upon its hinge joint can be firmly fixed in any desired position by
the said adjusting struts and the back being also adjustable as usual our present
improvements thus afford increased facility in operating with the camera as well as
in speed in setting up and folding and effects considerable economy of the space
occupied by the folded camera as by our present improvements we are thereby
enabled to make such camera very compact.
The spring bolt or spring bolts a are arranged and mounted in the lower part 61
of the detachable front b to engage with the corresponding eyelets or slots at c in.
or on the base board d (or vice versa) formed to receive said bolts in a similar
manner to an ordinary door latch as shown-the knob or projection a¹ being rigidly
connected to the horizontal bolt a and moved horizontally towards each other by
the hand of the operator and on release are pressed outwards by suitable springs
(such as those shown). When the parts are arranged vice versa (as just previously
mentioned) the spring bolts a would be arranged and mounted in or on the base
board d-for instance the bolts a would be arranged in a raised part or projecting
piece fixed on the base board d-while the eyelets (to receive the ends of said bolts)
are mounted on the bottom part of the detachable front b and the operation of the
various parts is the same as before.
These bolts a are thus self engaging and the slots etcetera to receive same may be
arranged in two (or more) separate positions as illustrated in Figure 1. so as to
readily set up the front b at a greater or less distance from the focussing screen
as desired.
Having now particularly described and ascertained the nature of our said inven-
tou and in what manner the same is to be performed we declare that what we
claim is.:-
1. In a photographic camera of the ordinary "bellows" type the combination

page_text: therewith of a detachable "front" (or part carrying the lens) b having spring
bolts a a' therein to engage in corresponding eyelets.or holes e arranged in different
positions on the base board d-or vice versa-substantially in the manner and for
the purposes herein before set forth and illustrated in the drawings hereunto
annexed.
с
2. In a photographic camera of the ordinary "bellows" type the combination
therewith of detachable "front" (or part carrying the lens) 6 having spring
bolts a a' therein to engage in corresponding eyelets or holes e arranged in different
positions on the base board d-or vice versa-and having adjustable struts such as f
arranged to act substantially in the manner and for the purposes hereinbefore set
forth and illustrated in the drawings hereunto annexed.
3. The use and application of spring bolts or catches for setting up the loose
front or part 6 in position on-and hingeing or connecting same to the base
board d substantially in the manner and for the purposes herein before set forth.
