DAVID HENDERSON HOUSTON of Hunter, Cass County, North Dakota
U.S.A.. Grower of Seed Grain do hereby de lare the nature of this invention to
be as follows:-
The object of the invention is to provide a simple & compact aparatus which
can be readily and easily carried and which can be quickly adapted for instantaneous
or time exposures as may be desired.
The invention comprises a case which contains all the operating mechanism of
the aparatus, which case may be constructed rectangular in shape with light-tight
joints. This case is constructed with an open front, and on the top of said case is
placed a level extending longitudinally of the case, said level having its centre
adapted to align with a sight on the top of the case.
To assist in aiming the instrument I provide marginal sights on the frame on
either side of the lens-tube by means of which the operator is enabled to see at a
glance exactly what amount of field the lens in use on the instrument will cover as
he has previously set the marginal sight to the proper positions in line with the
indicating marks on scales on the sight plate so that they will take in the same
number of degrees as the angle of his lens when in use will admit, whereby the
operator is not required to view the field through the camera every time a picture
is taken, and a more serviceable method employed.
A fiame is adapted to fit snugly in the case, and the front of said frame projects
beyond the edges thereof and forms a front for the case, and fits flush therewith to
exclude all light from the interior of the aparatus. This front piece is provided
with a rabbet joint, and after being placed in the case the parts are fastened
together by suitable clasp devices or hooks.
The front of the aparatus carries the sight plate which is fitted on and attached
to the upper edge of the front, said sight plate being provided with a central sight
the adjustable side sights and the scales adapted for use in connection with the side
sights to indicate the range of field of the camera. In the centre of this front is
a telescopic section which can be telescoped within the frame or projected therefrom
when it is desired to use the apparatus. To accomplish the telescopic movement
of the section without allowing the rays of light to enter the apparatus I construct
said section with flanges which lap over the frame, and in the edges of said frame
are secured strips of packing. I also provide a light excluding slide which can be
adjusted in place and used as may be desired. The side is fitted in suitable guides
or ways provided on the inside of the telescopic section and when it is desired
to prevent the rays of light from entering the camera before the apparatus is to be
used or when adjusting any of the parts thereof, this slide can be closed across
the section between the lens or light inlet of the camera and the sensitized film
at the back rear side thereof. This slide can be adjusted from one side of the
section, as ready access can be had thereto when the section is projected beyond or
drawn outward from the casing and in front of the camera, as will be readily
understood. By this telescopic construction of the section a considerable amount
of valuable space is saved because the section can be moved into the interior of
the frame or case when the appatus is not in use and it then presents a compact

page_text: form suitable for transportation which is especially desirable in this class of
-camera.
When the apparatus is to be used the section can be produced until the flanges
engage with the front of the frame.
In the back of the case or frame is an aperture and a slide is arranged to
operate in grooves to close or open said aperture as desired, the aperture disclosing
a ground glass arranged in the frame or case inside of the slide.
Secured to the front of the camera frame and casing on either side of the
telescopic section are two light excluding partitions or divisions which protect the
rolls of film hereinafter mentioned, from the action of the light passing through
the lenses.
The supply spool is secured on a shaft which is journalled in bearings in the
frame and it has a slot or opening in which one end of the film is secured and then
the film is wound on the spool until it is full.
The shaft on which the spool is secured is fastened in place by means of a cap
and pin which form a bearing for said shaft. The film is wound upon the supply
spool and the fiee end thereof is passed around a measuring and guide roller
secured on a shaft across the front face of the ground glass.
From thence said film passes around another guide roller secured on a shaft and
thence around another spool. The film may be wound on the take up spool in
the reverse direction to the winding of the film on the supply spool or the film
may be wound on the take-up spool in the same manner as the supply spool, so
that both of the spools may turn in the same direction and the heads or handles
rotate simultaneously in the same direction, whereby the operation of the rolls and
adjustment of the film are greatly facilitated. Secured on the partitions or
divisions and projecting over the spools are two spring arms which carry bearing
rollers. These bearing rollers are adapted to bear on the film wound on the spools
respectively and serves the purpose of preventing the end of the film from flying
loose when the spool is being placed in the spool frame or being taken from said
frame. The film can then be wound tightly on the spool and the compact
wrapping preserved and any tendency of the film to unwind is prevented. The
caps or bearing plates for said rolls have corrugated peripheries and a spring break
is secured on the frame and provided with projecting arms arranged to bear against
the corrugated edges of the caps said springs having slight bends or projections
which fit in the corrugations and operate to steady the rotation of the spools.
The supply spool is constructed of two pieces secured together in a suitable
manner and the larger piece has a hole square or polygonal in cross section in which
the shaft is fitted.
The guide roller is provided with perforators at either end of the same which
project slightly beyond the surface of said roller and perforate the sensitized filin
at each rotation. Thus every length of the film which is measured off, in a
manner hereinafter described is perforated and marked by the perforaters, two,
three or more times and these perforations indicate to the operator the lines of
division of the film to divide the several pictures preparatory to development.
The circumference of the measuring roller is such that it will require three
revolutions thereof to mark the limits of each picture length and the operator can
thus readily tell where to divide the pictures by counting the perforations.
In the corner of the case where the guide and measuring rollers are located are
curved recesses, and said rollers extend into said recesses. The film, which passes
around the roller close to the frame, extends across the face of the ground glass aud
around the other guide roller. After passing around the guide roller in the same
direction as it passes around the measuring roller the film may be crossed to the
inside of the take-up spool and secured thereon to be wound up as operated.
To enable the operator to manipulate the supply and take up the spools the
shafts on which they are secured extend through the frame and are provided with
ratchet wheels or caps as heretofore described and the shafts pass only half way
through the caps thus leaving a hole for inserting a key which is fitted through
A

page_text: openings in the case provided for that purpose. As the take-up spool is rotated to
present a new surface on the film the supply spool is also rotated and the spring
arms which bear on the corrugated peripheries of the caps regulate the movement
of each spool and cause them to rotate simultaneously & regularly, the pro-
jections 15 fitting in the recesses in the periphery of the caps.
The lens holding tube is arranged to slide or telescope in the telescopic front
section and this tube is provided with annular flanges on the inner and outer ends
respectively. The lens holding tube fits snugly in the opening provided for it in
the section, and the flanges engage with an annular ring or cap having packing
which fits around the opening in said section aurl thus the lens holding tube is
adapted to slide in and out of the telescopic section and at the same time a light-
tight joint is preserved throughout, which is necessary in this class of inventious.
These flanges may be properly designated as the caps of the cylinder forming the
outside lens holding tube, as they are screwed to the respective ends of said tube
and the inuer flange or cap has an inward projection constituting the support for
the interior tube for holding the lenses.
In the rear part of the frame the light excluding divisions extend almost to the
back of the interior side of said frame and between the back ends of the divisions
are two film-edge-holders extending between said divisions which film-edge-holders
hold the edge of the film in proper position as it passes along from one guide roller
to the opposite guide roller. The divisions are secured to the front of the case and
they are held firmly in place between the top and bottom of said frame by bolts
which clamp the top and bottom together and the divisions are held rigidly
between them.
The telescopic front section of the holder is arranged to slide easily in the
opening provided for it in the front, and when extended the flange on its rear edge
fits flush against the partitions and front, and the packing serves to form an
additional precaution against admitting light to the interior of the holder. The
lens-tube also slides or telescopes into the front section and the interior of the
holder and also has packing to exclude the light, and the lens tube is provided
with a scale on its outer surface by means of which the operator is able to
determine after a little experimenting exactly how far to project the lens tube in
order to obtain the correct focus and the scale is read with reference to its position
to the cap around the opening in the telescopic front section.
When the operator desires to present a new section or surface of the film in its
proper position for an exposure the take up spool is turned which causes the film
to unwind from the supply spool and pass to its proper position behind the lens
such section or surface of the film occupying the space at the rear of and between
the lines of the light excluding division. After passing from the supply spool the
film
goes around the measuring and guide roller and at each rotation thereof the
film is marked or perforated by the perforators every third mark of which
perforators designates the exact dividing line between the latent impressions.
A modified construction of the holder consists essentially in securing the lens
tube on a moveable piece which is arranged to slide vertically in the front of the
holder. This construction permits the lens to be moved up or down and when not
in use the lens tube can be moved backward into the interior of the holder as in
the preferred construction.
In another modified form, the glass, the slide, and aperture are omitted and the
end walls of the holder and the partitions or divisions are made of a light metallic
substance which secures greater space with the same size holder.
When it is desired to adjust the camera the sliding or telescopic front is drawn
outward to its full limit and the lens tube projected or adjusted to the proper
focal point by focusing the lens on the ground glass on the inside of the back
holder and the operator notes the position of the lens tube by observing the
position of the scale in relation to the ring or cap through which the lens tube slides.
The lens having once been adjusted to the proper focal point it will be found to
be correct when again placed at the same position on the scale for any view that

page_text: includes only distant objects and those not nearer the instrument than the depth
of focus of the lens used will include in proper focus.
By very little experimenting and noting results by focusing objects at different
distances the operator will be able to know just how many degree marks on the
scale to allow for any estimated distance between the instrument and the principal
field of view thus obviating the necessity of finding the focus on the view by
an adjustment of the image on the ground glass of the instrument every time before
a view is made.
I, DAVID HENDERSON HOUSTON, of Hunter, Cass County, North Dakota
U.S.A. Grower of Seed Grain, 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 object of this invention is to provide a simple and compact apparatus which
can be readily and easily carried and which can be quickly adapted for instantaneous
or time exposures as may be desired.
With these ends in view my invention consists in the combination with a suitable
enclosing case, of two transverse light excluding divisions situated interiorly within
the case at suitable distances from the ends thereof and from each other, whereby
a central compartment with two isolated end compartments is provided within the
case, a supply spool supported in one of the end compartments, and a take up spool
in the other end compartment, said enclosing case provided with a
light inlet in
the front thereof, opposite the central compartment, or with an equivalent lens
mounted on the case in line with the central compartment therein and adapted to
project an image on the film which passes from the supply spool to the take
up spool at the rear of the light excluding divisions, as will be hereinafter more
fully described.
My invention further contemplates reversing some of the parts of a roll holding
mechanism, and placing the guides for the sensitized film at the back interior side
of the holder, also the guide rollers I place at the back interior side of the holder,
whereby much valuable space is saved and the instrument compacted into small
convenient form.
My invention further contemplates a suitable frame which contains the operating
mechanism and the lens mounted in front thereof, which frame is arranged to fit
snugly in an enclosing case, its front forming one of the sides of the case.
My invention further contemplates a movable front which is arranged to
telescope within the frame, which front can be quickly projected in the practical
use of the apparatus, the lens tube being carried by said telescopic front and
adapted to slide within the front.
The advantages obtained by a photographic apparatus constructed in accordance
with my invention, are numerous and will be pointed out hereinafter.
I aim to construct an apparatus in compact form for easy and convenient trans-
portation, which can be quickly adapted for operation, and to arrange the various
parts and the lens tube to facilitate the operation of the apparatus.
The invention further consists in the novel combination of devices and peculiar
construction and arrangement of parts as will be pointed out and claimed herein-
after.
To enable others to more readily understand my invention, I have illustrated

page_text: the same in the accompanying drawings, forming a part of this Specification, and ·
in which :-

11
Fig. 9 is a view, partly in section of the spool shaft.
Referring to the drawings, in which like letters and numerals of reference denote
corresponding parts in all figures, A designates the case which contains all the
operating mechanism of the apparatus, which case may be constructed rectangular
in shape with light-tight joints.
This case is constructed with an open front, and on the top of said case is placed
a level G extending longitudinally of the case, said level having its centre adapted
to align with the sight V₁ on the top of the case, as shown by the plan view Fig. 1
of the drawings.
To assist in aiming the instrument, I provide the marginal sights 10 on the
frame on either side of the lens-tube, by means of which the operator is enabled to
-ee at a glance exactly what amount of field the lens in use on the instrument will
rover as he has previously set the marginal sight 10 to the proper positions in line
with the indicating marks on the scales, S', S', on the sight plate R by moving
them in the slots T₁, T', so that they will take in the same number of degrees as
the angle of his lens when in use will admit, whereby the operator is not required
to view the field through the camera every time a picture is taken, and a more
serviceable method is employed.
A frame M is adapted to fit snugly in the case A and the front B of said frame
projects beyond the edges thereof and forms a front for the case and fits flush
therewith to exclude all light from the interior of the apparatus. This front piece
is fitted with a rabbet joint V" and after being placed in the case the parts are
fastened together by suitable clasp devices or hooks 1, as desired.
The front B of the apparatus carries the sight plate R which is fitted on anl
attached to the upper edge of the front B as shown by Figs. 1 and 2 of the
drawings, said sight plate R being provided with the central sight V, the
adjustable side sights 10, and the scales S', S', adapted for use with the side
sights 10, 10, to indicate the range of field of the camera. In the centre of this
front B is a telescopical section C which can be telescoped within the frame or
projected therefrom when it is desired to use the apparatus. To accomplish the
telescopical movement of the section C without allowing the rays of light to
enter the apparatus, I construct said section with Hanges 2, 3, on its inner and
outer edges which flanges lap over the frame and in the edges of said frame
are secured strips of packing W¹. I also provide the light excluding slide O
which can be adjusted in place and used as may be desired. The slide O is
fitted in suitable guides, or ways, o provided on the inside of the telescopical
section, C, as shown by Fig. 3 of the drawings, and when it is desired to prevent
the rays of light from entering the camera before the apparatus is to be used, or
"

page_text: when adjusting any of the parts thereof, this slide can be closed across the
section, C, between the lens or light inlet of the camera and the sensitized film
at the back, rear side thereof. This slide O can be adjusted from one side of the
section C as ready access can be had thereto when the section C is projected
beyond or drawn outward from the casing and front of the camera, as will be
readily understood. By this telescopical construction of the section C a con-
siderable amount of valuable space is saved because the section can be moved into
the interior of the frame or case, when the apparatus is not muse, and it then
presents a compact form suitable for transportation, which is specially desirable in
this class of cameras..
When the apparatus is to be used this section C can be projected till the
flanges 2 engage with the front B of the frame.
In the back of the frame or case A is an aperture N, and a slide K is
arranged to operate in the grooves 4 to close or open said aperture as desired,
as shown by Figs. 3, and 4, the aperture disclosing a ground glass J arranged
in the frame or case inside of the slide K.
Secured to the front B of the camera frame and casing on either side of the
telescopical section C, are two light excluding partitions or divisions E, E, which
protect the rolls of film hereinafter mentioned, from the action of the light passing
through the lenses. The supply spool T is secured on a shaft P which is journalled in
bearings in the frame M, as shown by Fig. 5 and it has a slot or opening 12 in which one
end of the film is secured and then the film is wound on the spool until it isfull. The
shaft on which the spool is secured is fastened in place by means of a cap Q and
pin Qwhich form a bearing for said shaft. The film is wound upon the supply
spool T, and the free end thereof is passed around a measuring and guide roller H¹
secured on a shaft I, across the fiont face of the ground glass. From thence
said film passes around another guide roller H secured on a shaft I and thence
around another spool V. The film may be wound on the take up spool V in the
reverse direction to the winding of the film on the supply spool T, or the film may
be wound on the take up spool V in the same manner as the supply spool so that
both of the spools T and V may turn in the same direction and the heads or
handles thereon rotate simultaneously in the same direction whereby the operation
of the rolls and adjustment of the film are greatly facilitated.
Secured on the divisions or partitions E and projecting over the spools T,
and V are two spring arms Y which carry bearing rollers X. These bearing
rollers are adapted to bear on the film wound on the spools T, and V, respectively,
and serve the purpose of preventing the end of the film from flying loose when the
spool is being placed in the spool frame or being taken from said frame. The film can
then be wound tightly on the spool and the compact wrapping preserved, and any
tendency of the film to unwind is prevented. The caps or bearing plates for said
rolls have corrugated peripheries as shown in Fig. 2, and a spring brake is secured
on the frame and provided with the projecting arms 13, 14, as shown by Fig. 2,
of the drawings, arranged to bear against the corrugated edges of the caps, said
spring arms having slight bends or projections 15 which fit in the corrugations and
operate to steady the rotation of the spools T, V.
The supply spool T is constructed of two pieces 16, 17, secured together in a
suitable manner, and the larger piece 16 has a hole 8, square or polygonal in cross
section, in which the shaft P is fitted.
The guide roller H³ is provided with perforators L at either end of the same
which project slightly beyond the surface of said roller and perforate the sensitized
film at each rotation. Thus every length of the film which is measured off, in a
manner hereinafter described, is perforated and marked by the perforators L two,
three, or more times, and these perforations indicate to the operator the lines of
division of the film to divide the several pictures preparatory to development.
The circumference of this measuring roller H' is such that it will require three
revolutions thereof to mark the limits of each picture length, and the operator
can thus readily tell where to divide the pictures by counting the perforations.

page_text: In the corner of the case where the guide and measuring rollers are located,
are curved recesses A2, and said rollers extend partially into said recesses. The
film which passes around the roller, close to the frame, extends across the face
of the ground glass and around the other guide roller H. After passing around
the guide roller in the same direction as it passes around the measuring roller H',
the film may be crossed to the inside of the take up spool and secured thereon to
be wound up as operated, or it can be wound as shown in Fig. 4.
To enable the operater to manipulate the supply and take up spools T, V,
the shafts on which they are secured extend, through the frame M and are
provided with the caps or ratchet wheels Q, as heretofore described, and the
shafts pass through the caps Q thus leaving a shank to engage a key Tas
shewn in Fig. 5. The key is fitted through openings Q", in the case A,
provided for that purpose as shown by Fig. 1 of the drawings. As the take up
spoel V is rotated to present a new sui face on the film, the supply spool T is also
rotated, and the spring arms 13, 14, which bear on the corrugated peripheries of
the caps Qas shown by Fig. 2 of the drawings regulate the movement of each
spool and cause them to rotate simultaneously and regularly; the projections 15
fitting in the recesses in the periphery of the caps.
The lens holding tube is arranged to slide or telescope in the telescopical
front section C and this tube C' is provided with the annular flanges F1 and Fon
the inner and outer ends respectively. The lens holding tube C₁ fits snugly in the
opening provided for it in the section C and the flanges F¹ F" engage with an
annular ring or cap 9 having packing W which fits around the opening in said
section C; and thus the lens holding tube is adapted to slide in and out of the
telescopical section C and at the same time a light-tight joint is preserved through-
out, which is necessary in this class of inventions. These flanges F¹, F" may be
properly designated the caps of the cylinder forming the outside lensholding tube
as they are screwed to the respective ends of said tube, and the inner flange or
cap Fi has an inward projection E' constituting the support for the interior tube
for holding the lenses, as shown in Figs. 3, and 4.
In the rear part of the frame the light excluding divisions E extend almost to
the back interior side of the said frame, and between the back ends of the
divisions E, are two film edge holders F, extending between said divisions E, E
which film-edge-holders hold the edge of the film in proper position as it passes
along from one guide roller to the opposite guide roller. The divisions E are
secured to the front B of the case A as clearly shown in Figs. 3, 4, 8 and 9 of the
drawings and they are held firmly in place between the top and bottom of said
frame by the bolts X", X", which clamp the bottom and top together and the
divisions are held rigidly between them.
The telescopic front section C of the holder is arranged to slide easily in the
opening provided for it in the front B, and when extended the flange 2, on its rear
edge fits flush against the partitions E and front B, and the packing W₁ serves to
form an additional precaution against admitting light to the interior of the holder.
The lens tube C' also slides or telescopes into the front section C and the interior
of the holder, and also has packing W to exclude the light, and the lens tube is
provided with a scale D' (Fig. 6) on its outer surface, by means of which the
operator is enabled to determine, after a little experimenting exactly how far to
project the lens tube in order to obtain the correct focus and the scale is read with
reference to its position to the cap 9 around the opening in the telescopical front
section C.
When the operator desired to present a new section or surface of the film in its
proper position for an exposure, the take up spool is turned which causes the film
to unwind from the supply spool T and pass to its proper position behind the lens,
such section or surface of the film occupying the space at the rear of and between
the lines of the light excluding divisions E, E. After passing from the supply
spool T the film goes around the measuring and guide roller H¹ and at each rotation
thereof the film is marked or perforated by the perforators L, every third mark

page_text: of which perforators designates the exact dividing line between the latent
impressions.
In Fig. 4 I have illustrated a modified construction of the holder which consists
essentially in securing the lens tube C¹ on a movable piece D which is arranged to
slide vertically in the front B of the holder. This construction permits the lens
to he moved up or down and when not in use the lens tube can be moved backward
into the interior of the holder as in the preferred construction.
I have shown a modified construction in Figs. 7 and 8. The glass J, slide K,
and aperture N (shewn in Fig. 8) are omitted in Fig. 7, and in Fig. 8 the end
walls 20 of the holder, and the partitions or divisions E, E, (in both views) are
made of a light metallic substance, which secures greater space with the same size
holder.
When it is desired to adjust the camera, the sliding or telescopical front C is
drawn outward to its full limit, and the lens tube projected or adjusted to the
proper focal point by focusing the lens on the ground glass J on the inside of the
back of the holder and the operator notes the position of the lens tube by
observing the position of the scale D' in relation to the ring or cap 9, through
which the lens tube slides. The lens having once been adjusted to the proper focal
point it will be found to be correct when again placed at the same position on the
scale D', for any view that includes only distant objects and those not nearer the
instrument than depth of focus of the lens used will include in proper focus.
By very little experimenting and noting results by focusing objects at different
distances, the operator will be able to know just how many degree marks on the
scale D to allow for any estimated distance between the instrument and the
principal field of view, thus obviating the necessity of finding the focus on the view
by an adjustment of the image on the ground glass of the instrument every time
before a view is made.
In preparing the apparatus for operation, the spool frame M is withdrawn from
the case A, and the spool T wound with a sensitized film is properly placed in the
holder. Then the spool shaft P is passed down through the centre of the spool,
thereby pivoting the spool in the frame M; the end of the film is then passed
around the measuring roller, then across the back interior side of the holder and
around the roller H, thence the film may be crossed to the inner side of the take
up reel V, or it may be taken directly up to the same, and it is secured thereto to
be wound, after the picture is taken. The frame containing the operating
mechanism can then be replaced in the case A, which forms a light tight covering
and unites in a light-tight mauner with the front B of the case by the rabbet
joint V. See Fig. 3.
By means of the centre sights V₁ the operator is enabled to aim his camera
direct for the centre of the field required to be impressed on the film, and by the
marginal sights 10, 10, the operator is enabled to see at a glance exactly what
amount of field the leus then in use on the instrument will include as he has
previously set the sliding marginal sights 10, 10, to take in the same number of
degrees as the angle of his lens will admit; thus dispensing with the necessity of
focusing on the ground glass before making each picture. The film, having
received the latent impression, can now be wound on the reel or
take up
spool V by the aid of the key T" and every picture length of the film is perforated
by the perforators L on the roller H', which perforators indicate to the operator
where the divisions are to be made to divide the several latent impressions
preparatory to development.
