IMPROVEMENTS IN PORTABLE PHOTOGRAPHIC CAMERAS AND CHANGE BOXES
Year: 1885

page_text: I, SCOTTO CLARK NASH of No 405 Market Street Harrisburgh in the State of
Pennsylvania United States of America, Manufacturer do hereby declare the
nature of said Invention for "IMPROVEMENTS IN PORTABLE PHOTOGRAPHIC
CAMERAS AND CHANGE BOXES" to be as follows:-
This camera is especially available for field use, so that tourists, amateurs and
others, can carry a number of plates, fully protected from the light, and bring into
focus any desired one of the several plates without exposing either of the other
plates.
I make use of a box containing a belt of plate holders, the glasses or plates
in which are at opposite sides of the holders, and there are sliding covers over
the box.
A camera is movably received upon the top of the plate holder box and contains
a lens at one end, and a movable cover at the other end, also an adjusting device
for holding the movable focus glass, and for grasping and holding in place the plate
while the picture is being taken.
The camera is reversible so that it may be turned end for end upon the box and
used in connection with the plates at the other sides of the plate holders, and I
employ a counting device by which, in connection with a list made at time of
filling the plate-holders, the operator is enabled to know at any time, without
opening the box, the exact position of each plate and to bring into the proper plane
for exposure the kind of plate best adapted to any desired view. Thus may be
easily kept an accurate account of the plates as they are successively exposed and
the risk of double exposures is entirely avoided.
I also provide for covering the plate in sections so as to take small pictures upon
parts of the plate when a part of the sectional cover has been removed.
The base of the camera is usually provided with a plate by which it is screwed
to the top of a tripod or stand. Upon this plate is a box that contains the chain or
belt of sensitized plates hereafter described.
The box is rebated around its lower inner edge for the reception of the base plate
so that light will be excluded, and the parts may be screwed together by screws,
but usually there will be side pieces made permanently with the base and recessed
ED

page_text: into the inner faces of the box so that the axle of the chain of pictures, passing
through both the box and the side pieces will hold the base and box together.
In the inner faces of the box there are grooves, and in the ends of the box there
are slots for the reception of the sliding lids.
At
These lids are cach preferably made of transverse slats glued upon a piece of
canvas so as to be flexible and hang down out of the way when drawn out.
the inner end of each lid there is a cross lip to prevent the lid being pulled out
too far and to aid in intercepting any light, and at the outer end there is the cross
bar that closes tightly against the end of the box when the lids are slipped in.
I also prefer to introduce velvet or fur at the slots for the lids to pass through, so
that the pile of the velvet will more effectually exclude light but not interfere with,
the movement of the slide lids.
When the slide lids are closed the plates contained in the box are effectually
enclosed from the action of light.
There is a movable camera that is applied upon this box as hereinafter described
and when so applied the lids can be withdrawn and either one of the sensitized
plates turned up into the focus and the picture taken upon the same and then the
plate can be turned down into the box and the lids closed again.
In transportation the camera and the box can be carried together or separate.
Before describing the camera box I will describe the chain of plate holders.
Each plateholder is preferably of wood in the form of a frame with a central
diaphragm or partition so that there are recesses at opposite sides for the reception
of the sensitized plates.
Each plate holder has ears to hold the bottoms of the plates in place and turn
buttons at the top by which the plates are buttoned in. A bow spring at the back
of each plate fastened upon the partition presses the plate forward against the ears
and buttons so that the surface may be properly in focus when acted upon by the
adjusting device hereafter described.
. One edge of each plate holding frame is firmly fastened to the chain or belt that
connects the holders. I prefer to use a strong woven fabric or chamois skin
reinforced by, longitudinal lines of stitching for the belt and to apply plates of
metal and screws to clamp the belt to the plate holders. The depth of the box is
sufficient to receive the plate holders when placed one upon the other and the axle.
is across the middle of the box so that the picture holders can be all on either side
of the axle, or else some on one side and some upon the other side while one
of the plate holders is in a vertical position for receiving the picture.
The axle is square and passes through a square roller upon which are teeth
entering mortices in the plates and recesses in the inner edges of the plate holders,
so that the roller when turned will move the plate holders, swinging them up in
succession into the camera and then down into the other end portion of the box.
There is a partition inside the belt and a roller around and beneath which the belt
passes. This roller has its axles in end bearings upon the partition and this
partition can be moved up or down between the side pieces and clamped so as to
strain the belt carrying the plate holders and prevent its becoming too slack.
There are bow springs fastened upon the base upon which the outer ends of the
plate holders rest to prevent the holders straining the belt by their leverage, and
these springs yield and allow the plate holders to settle down bodily by the..
accumulated weight of the holders.
These springs also raise the plates as they are lifted and swung up successively.
The ends of the roller are cylindrical so as to take proper bearings in the side
pieces and there are cylindrical bushings around the axle where it passes through
the box so as to form proper journals for such axle. The knobs upon the ends of the
axle are used for revolving the same, and to each knob a gear wheel is fastened, and
upon the sides of the box there are dials of paper or other suitable material fastened,
and over these dials are the count wheels each having a hole through it. These
count wheels gear into the wheels upon the knobs hence they are revolved first in
one direction and then in the other as the belt of plate holders is moved.
บ น

page_text: The operator when taking his pictures is usually at one end of the box and
camera, and in using the right hand will turn the knob at that side of the camera.
I therefore mark the dials so that when all the plate holders are in one end, an
arrow is exposed through each wheel indicating the positions of the plate holders.
When the first plate holder is turned up the number 1 is exposed at one count
wheel, and the number 12 at another count wheel, and when the. second plate.
holder is brought up to place the numbers 2 and 11 are exposed, and so on, the
operator knowing by the direction of the lens of the camera which of the two
plates is being acted upon by the light, and by a list he can mark the names of
places or persons to each picture, and in this manner determine which plates have
been used without opening the box.
It is preferable to place a number upon one corner of each sensitised plate while
in the dark room and place them in the order indicated in the plate holding box.
The camera itself is composed of the sides top and front and there is a movable.
cover to give access to the ground glass in focussing.
It is preferable to employ a cover of slats upon a canvas lining and to provide
grooved segmental ways in which the ends of the cover may run, and a double top,
so that the cover may be moved up and pass in between the two parts of the top
when the focus is being taken and the same is to be drawn down to exclude the
light before either of the lids is withdrawn.
Around the top edges of the box there are grooves and around the bottom edges
of the camera, there are ribs fitting these grooves or vice versa so that light .may
be effectually excluded at the joints.
The camera may be placed upon the box with the lens tube in either direction,
the parts being made to fit, so that when pictures are to be taken upon the plates 1
to 6, the camera will be placed upon the box in one direction and when pictures
are to be taken from 7 to 12, the camera will be reversed.
Upon the sides of the box there are the connecting plates, each is attached by a
screw and there is a second screw, the hole for which is slotted transversely of the
plate and there is a hole at the upper end of the plate and a stud upon the camera.
The plates are made of spring brass, and the upper ends bent outwardly so that
the studs pass them back as the camera is set down to its place upon the box.
The slots for the screws allow the plates to be swung so that the holes in the
upper portions will receive the studs and hold the camera and box together, and
when they are to be separated the upper ends of the spring plates are drawn back
and swung partially aside so that the studs are free and the camera can be lifted
and reversed.
The front end of the camera is made double and to the lens tube there is a
septum plate firmly attached.
This septum plate is between the two parts of the double end and the lens tube
and septum plate can be moved laterally or up or down, to adjust the lens opposite
to the portion of the plate upon which the picture is to be taken, and no light can
pass into the camera laterally.
The frame holding the ground glass is made with an extension upon one edge,
preferably the left hand, with holes in it so that the same may be set over the pins
inside the camera case at that side. These pins however are not in the way of the
plate holders, and there are flexible shields of woven fabric or velvet, to intercept
lateral rays from the front to the back of the camera.
The adjusting and holding device for the focussing glass is also used for the
plate holders as they are brought up to place; this holding device is in the form
of a fork that is square in the shank and passes through a mortice in the side of
The outer end of this fork is round and has upon it a cylinder with a
the camera.
button head.
The spring within the fixed tubular case serves to project the fork and cylinder
outwardly but the screw in the notched slot in the case limits the movement.
When the screw is in the outer end of the slot the fork is entirely out of the
War of the alat hall

page_text: When the fork is pushed in and the parts turned so that the screw is held in the
first notch, the longer and forward end of the fork is brought into the path of a
plate fixed upon the edge of the plate holder, or a similar one upon the edge of the
frame of the ground glass and forms a stop, and when the fork is pressed in, the
said plate is received between the parts of that fork and firmly held until the fork
is drawn back.
It is to be understood that each plate is in the plane of the surface of the sen-
sitised plate or of the ground surface of the focussing glass, hence the sensitised.
surface when brought up to place occupies the same position as the ground glass
surface.
In order to cover any portion of the plate I make use of a shield in four sections,
two sections are upon tubular axles at the inner sides of the camera; the other
two sections are upon solid axles passing through the tubular axles and at the'
upper ends outside the camera, these axles are provided respectively with turn
buttons or heads firmly attached so that either section can be swung over the
plate as a shield and be held by a pin inserted vertically through the head.
When not in use these shields lie close against the inner surfaces of the sides of
the camera and the pins inserted through the holes in the beads hold them in
place.
Caps may be used to cover the heads, or turn buttons as a precaution against
light passing in but this is not required because the heads or turn buttons are flat
plates setting closely together and against the bottom of the recess they occupy in
the camera.
In this description I have referred to six plate-holders with twelve plates. By
simply increasing the depth of the box without adding in the least to its other
dimensions, a larger number of plates may be introduced.

Change Boxes.
I SCOTTO CLARK NASH of No. 405 Market Street, Harrisburgh in the State of
Pennsylvania, United States of America, Manufacturer, do hereby declare the
nature of my said invention for IMPROVEMENTS IN PORTABLE PHOTOGRAPHIC
CAMERAS AND CHANGE BOXES and in what manner the same is to be performed to
be particularly described and ascertained in and by the following statement:
This camera is especially available for field use, so that tourists, amateurs and
others can carry a number of plates fully protected from the light and bring into
focus any desired one of the several plates without exposing either of the other
plates. I make use of a box containing a belt of plate holders, the glasses or plates
in which are secured therein and there are covers over the box. A camera is upon
the top of the plate holder box and contains a lense at one end and a movable
cover at the other end; also an adjusting device for holding, the movable focus-
glass and for grasping and holding in place the plate while the picture is being
taken. The camera may be reversible, so that it may be turned end for end upon
the box and used in connection with the plates at the other side of the plate
holders; and I employ a counting device by which, in connection with a list made
at time of filling the plate holders, the operator is enabled to know at any time,
without opening the box, the exact position of each plate, and to bring into the
proper plane for exposure the kind of plate best adapted to any desired view.
Thus may be easily kept an accurate account of the plates as they are successively
exposed, and the risk of double exposure is entirely avoided. also provide for
covering the plate in sections, so as to take small pictures upon parts of the plate
where a part of the sectional cover has been removed.
In the drawing fig. 1 is a vertical section of the camera, fig. 2 is a sectional
plan through the shaft that turns the belt of plate holders-fig. 3 is an elevation at
one side of the camera-fig. 4 is a partial plan view of the adjusting device and of
the arms for moving the sectional covering plates-fig. 5 is a section showing the
arms for turning the sectional covering plates-fig. 6 is a section in larger size of
the adjusting and holding device for the focus glass and plates-fig. 7 is a view in
enlarged size at right angles to fig. 6-fig. 8 is a detached view of the sectional
covering plates-fig. 9 is an elevation of the lens holding disc and slide-fig. 10 is
a section of a camera adapted to a belt of double plate holders-fig. 11 is a
detached elevation of the support for the axle, the bushing for the axle and the
bow that acts as guide for the pins on the plate holders and fig. 12 represents the
cover that is applied to the outside of the camera.
The box A of the camera is usually provided with a plate a, by which it is
screwed to the top of a tripod or stand. Upon this plate is a box B that contains
the chain or belt of sensatized plates hereafter described. The base is rabbeted
around its edges for the reception of the lower edges of the camera box,-80 88 to
exclude light and the parts may be screwed together. The side pieces a are
permanently connected to the base A and are within the camera box.
The axle c passes through the box and also through the metallic side pieces abin
which are, bushings a³ shown separately in fig. 11.-These bushings have square
boles through them for the square axle c, and hence the bushings are turned with

page_text: the axles, and each bushing has a cylindrical journal entering a circular opening in
the side piece a forming a bearing in which the bushing may be revolved. Upon
the projecting edges of the bushing are four rounding notches for receiving the
pins a upon the edges of the plate holders E.
These plate holders are frames joined together by a belt of canvas or other
similar material securely attached to the edges of such holders, and the thickness of
the plate holding frames correspond to the thickness of the square shaft, hence the
chain of plate holders will be moved and one holder brought up to place each
quarter revolution of the axle c, and by that revolution the plate holders are
brought up in succession from the rear of the axle c, and conveyed down in front
of such axle c, there being a partition h¹ beneath the axle.
There may be a spring upon the base A, to partially support the weight of the
plate holders, (as seen at k, fig. 10), but by providing the metallic bows a', which
are outside the metallic bearing pieces a², so as to leave between these two parts,
slots that are parallel with the partition h¹, the pins a will remain in such slots
and keep the belt and the edges of the plate holders closely against the faces of the
partition h¹, so that the plate holders will be supported and stand out like brackets
from the partition. It is advantageous to place upon the two end frames or
portions of the belt of plate holders, small bracket pieces as that project down-
wardly against the surfaces of the partition and aid in supporting the weight of
the plate holders. The ends of these brackets a pass into recesses in the bed A.
In fig. 1 I have shown a covering plate k², that forms the end section in the chain
of plates and serves to exclude light from the front part of the camera base when
focusing the picture.
Each plate holder E is preferably of wood in the form of a frame, with a
diaphragm or partition e so that there may be recesses at opposite sides for the
reception of the sensitized plates numbered 1 to 12. Each plate holder may have
ears to hold the bottom of the plates in place, and turn buttons at the tops by
which the plates are buttoned in. A bow spring at the back of each plate, fastened
upon the partition e presses the plate forward against the ears and buttons, so that
the surface may be properly in focus when acted upon by the adjusting device
hereinafter described. One edge of each plate holding frame is firmly fastened to
the chain or belt that connects the holders. I prefer to use a strong woven fabric
or chamois skin reinforced by longitudinal lines of stitching for the belt and to
apply plates of metal i¹, and screws to clamp the belt to the plate holders. The
number of plate holders shown is six and the depth of the box A-B is sufficient to
receive these when placed one upon the other.
The square axle C in fig. 10 passes through a square roller h upon which are
teeth 15, entering mortises in the plates and recesses in the inner edges of the
plate holders, so that the roller h, when turned, will move the plate holders,
swinging them up in succession into the camera, and then down into the other end
portion of the box. The partition h¹ is inside the belt with a roller ², around and
beneath which the belt passes. This roller has its axles in end bearings upon the
partition and this partition h¹ can be moved up or down between the side
pieces and clamped so as to strain the belt, carrying the plate holders and prevent
its becoming too slack.
The camera box is made with a top N, sides M and a cover P which cover is
opened to observe the focusing glass and closed to exclude light before the plate is
brought into position for taking the picture..
In fig. 10 this cover P is shown as a range of slats fastened together by a lining
of canvas. There are grooves in the sides M for the ends of the slats and the cover
when opened slides in between the double top N.
The cover P is provided with side pieces P2, pivoted to the camera box at P³, and
the lower ends P are made with holes and spring over pins in the camera box as
the cover is closed down so as to hold the same.
:
There is preferably a bellows extension N1 between the camera box and the
frame that carries the lens holder and the rack bars 01 are fastened at their

page_text: outer ends to this frame O and slide through the loops o² and are moved by the
knobs o and their gear wheels so as to adjust the camera and focus the object or
nearly so, as the lens tube Q is usually made with an adjustment. The rack bars o'
are of comparatively thin sheet metal that will spring and allow for one rack bar
to be set out further than the other and thereby incline the frame and lens more
or less to the axis of the camera. This is sometimes a convenience in directing the
focus upon some particular part of the plate.
The septum plate Q1 is capable of being slid transversely of the camera in the
slides that are provided for. it at the front of the frame O. The lens tube Q is set
into a metallic disk Q that is recessed into the septum plate Q' and secured by
fingers Q-fig. 9, and this lens tube Q is not central with the disc Q and when it
is desired to direct the line of vision upon any part of the plate, the disk can be
partially revolved to raise or lower the eccentric lens tube, and the septum plate Q¹
slipped laterally to bring the line of vision upon the centre or any desired part of
the plate.
In fig. 10 the septum plate Q1 is shown as attached directly to the lens tube
without the use of a disk, and the septum plate can be raised or lowered as well as
moved laterally.
The lid is preferably made of slats glued on a strip of canvas and it is slipped
in over the plates as they lie within the receptacle or box, and there is an end
piece c and plush facing to exclude light, and stops c¹ to prevent the lid being
drawn entirely out.
When the upper part of the camera box is made reversible so that two plates
can be used in each plate holder, then a second lid C¹ fig. 10 is provided so as to
cover up the chain of plates within the box B and effectually exclude light during
the time the upper part of the camera is moved and turned end for end. After the
upper part has been properly placed and secured the lids c¹ c³ can be withdrawn
and the plate holders and plates from either end of the box B brought up to
place. When this form of my improved camera is used a focusing glass 8 in a
separate frame is necessarily employed and this is placed in the box and the focus
adjusted while the lids C¹ C³ are closed and the cover P open. After the focus has
been adjusted the glass 8 is lifted out and the cover P closed, then the slide
cover C is drawn back and the plate holder and plate brought up to position and
held and the picture taken and moved down into the box B and the lid C² closed
before the focusing glass is again introduced.
The focusing glass 8 is by preference in the end plate holding frame as seen in
fig. 1. It is brought up to place and held and the lid C is slipped in to entirely
exclude light from the sensitized plate in the chain of plate holders before the
cover P is raised or the lens tube opened. After the focus has been adjusted the
cover P is closed, the lens tube covered, the lid C drawn back and the chain of
plate holders is revolved until the proper plate is brought up to position; such
plate is then held as next described and occupies the precise place of the surface of
the ground glass, the exposure is made, the chain of plate holders turned back to
confine them within the box B. In so doing the focusing glass s is brought up
to place, the lid C is closed in and the camera can be opened to focus another
picture.
Each plate holder in fig. 1 is adapted to one sensatized plate, it has a permanently
closed back of sheet metal, a spring to press the plate forward and nibs of sheet
metal at es under which the edge of the plate i is slipped and a spring es of sheet.
metal within the frame to act upon the edge of the sensatized plate i and hold it.
up behind such nibs e and there are nibs e at the outer ends of the spring e
behind which the lower edge of the plate is placed as the said plate is entered.
These nibs being in the same plane, hold the sensatized plate in place and do not
injure the picture and the plate is easily removed by pressing it down against the
spring until its edge is lifted clear of the nibs es.
Upon each plate holder is a plate u with a mortice behind it and the adjusting
and holding device is in the form of a fork.r that is square. in the shank. and.

page_text: passes through a mortice in the top of the camera, the outer end of this fork is
round and has upon it a cylinder with a button head. The spring within the
tubular case 3 serves to project the fork and cylinder outwardly, but the screw or
pin 25 in the notched slot in the case limits its movement. When the pin 25
is in the outer end of the slot, the fork r is entirely out of the way of the focusing
glass and plate holders. When the fork is pushed in and the parts turned so that
the pin 25 is held in the first notch, the longer and forward end of the fork r is
brought into the path of the plate u and stops the same, and when the fork is
pressed in, its rear prong passes down behind the plate u and the holder and plate
is reliably held in place.
It however is important to swing the top of the focusing glass backwardly or
forwardly to render the focus more perfect or to bring the vertical lines of the
objects vertically upon the plate, to allow for this I mount the adjusting and
holding fork and its parts upon the plate 5 that is upon the top of the camera and
can slide back or forth between stationary frictional guides 7 figs. 4 and 6 the hole
through the camera top being elongated to allow of this movement and the plate ³
entirely covering the same.
་
The fork remains in the position to which it may have been placed after the
focusing glass is swung down and stops and holds the sensatized plate in precisely
the same position.
In order to cover any portion of the plate I make use of a shield in four
sections. The sections are upon tubular axles 30 at the inner sides of
the camera.
The sections are upon solid axles 31 passing through the
tubular axles 30 and at the upper ends the respective axles are provided with
spring arms v³, vª, 7 beneath the respective covering plates that are slotted
segmentally for the upper ends of the spring arms to pass through, so that any one
or more of the sectional shields may be swung up in front of the sensatized plate
or focusing glass and a small prong at the end of the spring arm is used to hold
the same and its shield by springing up into the recess in the under surface of the
covering plate 28. The end of the arm is pressed down to disconnect this prong,
before swinging the section either way.
A follower strip № is mounted upon each axle 31 opposite the joint between the
pairs of shields and a spring 10 tends to swing this with the shields but it is kept
back by either the upper or lower shield and it is swung by the spring and covers
the joint between the upper and lower shield when these two shields are used at
the same time to cover half the plate.
In order to revolve the axle c the knobs 11, 12 are provided and to one of the
knobs, preferably the right hand one, a gear wheel 13 is fastened, and upon the side
of the box there is a dial of paper or other suitable material. It is preferable to
clamp this dial of paper between the small disk and the nut and this nut is of
larger diameter than the disk, so as to retain a circular plate that is behind the
dial and surrounds and turns freely upon the disk and the rim of this
circular plate forms a count wheel, there being teeth upon its periphery gearing
into the wheel upon the knob and there is an internal pointer that passes over
the surface of the dial. This dial has as many figures upon it as there are holders
in the chain of plate holders. These figures are preferably circular and made with
vertical and horizontal lines passing through the centres of the circular figures.
The relative sizes of the gearing are such that for every quarter turn of the
axle C, the pointer on the count wheel is moved from one circle on the dial to the
next and the operator places the circular figure of the dial marked "focusing
glass" opposite to the pointer when the focusing glass is in place, and the pointer
is moved to another circular figure on the dial each time the axle C is rotated a
quarter turn and another plate holder brought up vertically.
If a picture is taken on the entire plate the operator marks all the quarters on
that circle, but if only a half or a. quarter of the plate is made use of, the dial is
marked accordingly in the quarter circle sections, hence, the operator can tell by
inspection what plates have been used and bring into position any desired plate or

page_text: any part of any plate and after a picture has been taken, the knobs are turned to
move the plates back into the storage plate holder and to bring the focusing glass
into position and this is indicated upon the dial by the pointer.
If the plate holders are double and the camera box is capable of being turned
upon the base to take pictures at one side or the other of the plate holders, as seen
in fig. 10, then two dials should be used, one for the plates, at one side of the
holders, and the other for the plates at the other side of the holders, the right hand
one usually being employed by the operator.
.
It is preferable to place a number upon one corner of each sensatized plate
while in the dark room, and place them in the order indicated in the plate
holding box.
The flexible cover t for the camera is usually made of black plush lined with a
soft black fabric. I make the same with side and top portions united to a front
piece as seen in fig. 12, and this front piece has an opening through it and a flap t
to cover the lens holder. The flexible cover is connected to the front frame of the
camera by tacks or buttons at t so that it cannot become misplaced and it hangs
loosely and aids in keeping out light and also facilitates the inspection of the
focusing glass, especially as the flap P, as it is lifted, raises with it the flexible
cover and prevents the same falling down between the operator and the glass.
