PROVISIONAL SPECIFICATION.
Improved Apparatus for Printing from Photographic Negatives.
I, HENRI LOUIS MOREL, 126, Welbeck Terrace, Mansfield Road, Nottingham,
Photographic Artist, do hereby declare the nature of this invention to be as
follows:-
:
Each apparatus consists of a box of wood, metal or other material hinged
at one end to its bottom. The top has two parallel slits through it a suitable
width apart between which the paper to be printed is laid. Between the slots
a spring clip is secured at each end to firmly hold the ends of a negative plate,
each clip is carried by a right angled plate, passed through and held down by
springs within the box. Beneath each plate is a cam secured near the ends of a
shaft rocking in the sides of the box, the shaft projects through the box at one
end and carries a lever connected by a link to a rocking lever operated by a
cam outside the box at the end of a shaft provided with a hand lever.
The cam being partly turned raises the clips and negative plate to allow a
sensitised paper to be passed under it, the plate is then lowered and a printing
is made either by daylight or artificial light. The paper to be printed may be
only large enough to print one copy, or it may be of any length or any, number
of copies. The length of the paper being supplied from a roller near one end of
the, box inside the roll being pressed upon by a spring plate. The other end of
the paper is passed partly round a roller at the reverse, end of the box and
between it and an upper roller carried by the shaft terminating in a cam and
hand lever, one end of the upper roller carries a projecting stud for operating
a lever to strike a bell within the box at each revolution, the upper, roller is held
in position by a plate spring.
AX
The paper from the supply roller is passed up through one of the slots in
the top of the box then over the space between the slots and down through the
second slot to the upper roller, this roller after each printing is revolved once
to pass the print to the inside of the box and place another surface beneath the
negative for a second printing.
While the single sheet or roll to be printed is being placed in position the
negative plate is covered by a shutter hinged to one side of a slide which closes
one of the slots, the other slot being closed by a second slide, both slides being
carried by clips secured to the top of the box. While the printing is being made
the hinged shutter is raised.

I, HENRI LOUIS MOREL, of 126, Welbeck Terrace, Mansfield Road, in the City
of Nottingham, Photographic Artist, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:-
_
This invention relates to improved apparatus to be used in place of ordinary
printing frames, for printing on sensitized paper or the like, from photographic
negatives, and it has for its object to provide simple apparatus, which will inter-
mittently feed a band of sensitized paper or the like under a negative, and thus
permits of consecutive lengths of the band being rapidly exposed.
The apparatus is specially applicable for printing on highly sensitized paper
or materials, which require only a short time exposure to either artificial or
ordinary daylight, and are therefore difficult to manage in ordinary printing
frames.
The invention will be best understood by reference to the accompanying draw-
ings, in which
Fig. 1 is a sectional elevation, and
Fig. 2 a sectional plan of apparatus constructed according to my invention.
Fig. 3 is a plan, showing the negative holding mechanism and printing pad.
Fig. 4 is a plan of the middle part of the cover or top.
Like letters indicate like parts throughout the drawings.
According to my invention, the body of the apparatus is comprised of a prefer-
ably rectangular box or enclosed casing A, (see Figs. 1 and 2) preferably divided
by a horizontal partition A¹. The lower part of the casing A may if desirable
be made detachable from the upper part as shown.
The band of sensitive paper or material is mounted upon a transverse spool
or roller B, placed at one end of the interior of the casing, the axis of the
said spool being journalled in bearings B₁ B₁ formed in or on corresponding side
plates C C, secured to the inner sides of the casing A. These bearings are formed
as shown, so that the said spool may be readily lifted out of the casing for
refilling. The spool B is checked by springs B2 secured to the casing A. At
the free ends of these springs B2 is secured a pad B³, which bears on the surface
of the paper on the spool, and thus prevents the latter from over-running, as the
paper is drawn off.
The sensitized paper or material D (see Figs. 1 and 3) is carried from the
spool B, through a narrow transverse opening A2 in the top of the casing A, over
a printing pad E placed on the top of the casing, and under the negative plate H,
then down through a second transverse opening A³, into the interior of the casing
again.
Below the opening A³ (see Figs. 1 and 2) is a transverse pair of feed rollers F F,
between which the sensitized band of material is carried, and by means of which
it is fed from the spool B over the printing pad E.
The roller F is preferably formed of vulcanite or other hard substance, and
the ends of its axis are journelled in fixed bearings F2 F2 secured to or formed
on the plates C C. This roller is of such a diameter that it will feed the sensi-
tized band of material D, forward the requisite distance, in say one complete
revolution, or half a revolution. One end of the axle of this roller F (see Fig. 2)
is carried through the casing A, and is provided with a handle G, by means of
which the said roller is rotated by the operator.
The roller F is preferably made of elastic material such as india-rubber or

page_text: felt, and the ends of its axle are journelled in sliding bearings F3 F3, which latter
are mounted in guideways F F on the plates C C. The roller F is forced up
to the roller F, by springs F5 (see Fig. 1) acting on the sliding bearings F F of
the said roller 1, so as to grip the band of paper D between them.
From the feed rollers F F, the band of paper passes through an opening A' in
the partition A', into the lower compartment. The sides of this opening are
carried up to the feed rollers as shown in Fig. 1.
The negative plate H is carried by the following arrangement.
Each end of the negative H (see Figs. 1-2 and 3) drops into a horizontal
seat J formed at the upper end of a vertical slide J. The latter are carried
through narrow slots or openings formed in the top of the casing A on the
respective sides of the printing pad E, and are provided at their lower parts
with pins or extensions J, which slide in openings in extensions C₁ C¹ on the
side plates C C.
The ends of the negative plate H, are held in the respective seats J¹, by a
clip J³, which slides in guideways J on the said seat, so that its inner end may
be moved over or clear of the edge of the negative plate H, and is held in
either position by a screw J, passing through a slot J in the clip.
The negative plate H is raised as the band D of sensitized material is
fed forward, by raising the slides J which carry the negatives.
This is effected by a transverse shaft K (see Figs. 1 and 2) carried in bear-
ings K¹ K¹ formed in the side plates C C. This shaft is provided with arms LL
the free end of which engage with the lower edge of the respective slides JJ,
and thus raises them when the shaft K is rotated, against the action of springs L'.
The shaft K is also provided with an arm M, which is connected by a link M'
to one end of a lever M², which latter is pivotted at M³ to the plate C. The
other end of the lever M2 is provided with an anti-friction roller M, which is
in peripheral contact with a cam O on the axle of the feed roller F.
When the latter is thus turned to advance the band D of sensitive material,
the negative H is raised, and is again returned to its normal positions again by
the springs L', when the roller F has made say one complete revolution or half a
revolution, and has thus moved the band H forward the requisite distance.
If preferred the rocking shaft K may be dispensed with, and the slides J J be
raised by independent levers such as M, actuated by cams on or connected to the
feed roller.
Above the top of the casing A (see Figs. 1 and 4) is a cover P, provided with
an opening above the negative H, above this opening is a plate Q, which slides
longitudinally in guideways P on the cover 1.
This plate is also provided with an opening which is partially closed by a
vignetting mask R, which latter slides in guideways Q₁ in the plate Q, at right
angles to the movement of the latter The opening R on the vignetting mask
may thus be adjusted over any part of the negative H.
Hinged to the plate Pat S₁ is a frame S, over which a semi-transparent material
may be stretched, this may be turned down over the vignetting plate R.
At T on the plate Q is hinged a shutter T, which may be closed down over the
frame S, so as to totally exclude all light from the negative H, whilst the band D
of sensitive material is moved forward.
This shutter is preferably automatically closed by a spring coiled on the hinge
pin.
On the underside of the plate l' are two transverse guards U U¹, (see Fig. 1)
to shut off the light from that part of the sensitive band D, which extends beyond
the edge of the negative H.
The lower edges of these guards rests on the negatives, and in order that the
latter may be raised as described, each of the said guards is made in two parts
as shown, an upper fixed part U, and a lower part U₁ which slides over the upper
part.
The parts a a¹ (see Fig. 1) of the top of the cover A, are preferably hinged or

page_text: made detachable in order to remove and replace the sensitive band D), a guard a³
provided with an opening a³, is preferably placed under the hinged part a.
The end of the lower part of the casing A, may also be hinged or made
detachable from the main part, in order to remove the exposed part of the band
D from the latter.

invention and in what manner, the same is to be performed I declare that what
