PROVISIONAL SPECIFICATION.
Improvements in Photographic Printing Frames.
I, WILLIAM GRIFFITH HONEY of 15 Orange Grove Bath in the County of
Gloucester Photographer do hereby declare the nature of this invention to be as
follows:
-
My present invention relates to photographic printing frames and has for its
object a simple safe and expeditious means of releasing a part of the cover or back
in order to inspect the print from time to time during the progress of printing to
attain which I divide the back into two hinged portions or Haps which are secured
to a cross bar hinged to one side of said printing frame.
The two said hinged portions or flaps are kept in closed positions by means of a
spring which has one portion coiled around a cross rod secured at each end to a
screw or bolt which latter is fastened to said hinged cross bar. The ends of said
coiled springs are arranged to extend over each Hap respectively so that should a
flap be pulled backwards for the purpose of inspecting the progress of the print it
will automatically return to closed position when released.
The hinged centre bar which carries both said flaps is arranged with one end to
fit into a groove or recess formed on one side of frame and is secured in closed
position by means of a pivotted bar or catch.
I preferably arrange on one side and at the back of my said improved printing
frame an index or indices formed by means of undercut vertical or other grooves
wherein fit spring pointers arranged so that when they are pressed with the thumb
and finger they are easily moved and when released they remain in fixed positions
for instance where it is required to note the number of prints wanted and the
number of prints printed I fix to the side of one slot an index of figures with the
words wanted or required and to the side of another slot an index of figures with
the words printed and I manipulate the pointers as hereinbefore described.

COMPLETE SPECIFICATION.
Improvements in Photographic Printing Frames.
1, WILLIAM GRIFFITH HONEY of 15 Orange Grove Bath in the County of
Somerset Photographer 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 :-
My present invention relates to photographic printing frames and has for its
object a simple safe and expeditious means of releasing a part of the cover or back
in order to be able to inspect the progress of printing from time to time as required
to attain which I construct my improved printing frame as set forth in the accom-
panying sheet of drawings in which
Fig. 1 is a back elevation Fig. 2 a cross sectional elevation taken on line A B of
Fig. 1 and Fig. 3 is a plan of one arrangement of my improved photographic
printing frame and Fig. 4 is a back elevation of a modification of said invention.
Like letters of reference denote corresponding parts in each view.
Referring to Figs. 12 and 3 the frame C. is dovetailed or otherwise fastened
together in the ordinary manner and is preferably composed of wood.

page_text: The back is divided into two hinged portions or flaps D and D' which are
secured to a swing bar E by means of hinges and the said bar is secured to one
side of the frame C by a hinge h².
The two binged portions or flaps D and D₁ are kept closed up to said frame C
or in closed positions by means of a spring F which has one portion thereof coiled
round the cross rod G the latter being secured at each end by means of set screws
or bolts m in to the cross or swing bar E. The ends and of the coiled
spring F are arranged so as to extend over the flaps D and D¹ respectively so that
should a flap be pulled backwards for the purpose of inspecting the progress
of the print it will automatically return to closed position upon being released.
The swing or hinged bar E which carries both flaps D and D' as aforesaid is
arranged with its end e² to fit into a groove or recess c¹ formed on one side of
frame C for its reception and it is secured in a closed position by means of a
pivotted bar or catch e³.
I preferably arrange on one side and at the back of my said improved photo-
graphic printing frame indices H and II formed with grooves G and G¹ wherein
fit spring sliding fingers J and which are arranged as shown in plan Fig. 3 so
that by nipping their protruding portions and with the thumb and finger they
can be easily placed to any number required and when released will remain in
fixed position. For instance where it be required to index or note the number of
prints required to be printed and likewise the number already printed I fix or
mark at the sides of said grooves G and G¹ indices of figures as shown with the
words Required and Printed and should for instance the number of prints required
be fourteen I place the pointer at fourteen opposite Required as shown and as the
numbers are printed consecutively I move the index finger J' after every print
made and so keep a true register of the number of prints executed.
Referring to Fig. 4 the flaps D and D₁ are of two different lengths so that a
greater part of the print can be inspected from time to time or in fact the lengths
of the flaps D and D₁ may so vary that the whole of the print can be inspected by
pulling back the flap D the part of the sensitized paper bearing under the flap Di
merely being arranged to hold the print in position and not bearing on the exposed
part of the negative. In this arrangement I find it advisable to place a pivotted
bar or catch on the frame C at the end of the longer flap D in order to more
securely hold same in closed position when in the frame.
In printing the negative together with the necessary amount of sensitized paper
is placed in the frame C in the usual manner and subsequently the bar E is brought
over and fastened by means of the said catch e³ and the progress of printing may
be inspected from time to time in the manner hereinbefore described.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. In photographic printing frames the use of a hinged bar E in combination
with flaps D and D¹ hinged thereto substantially as described.
2. In photographic printing frames the combination with a hinged bar E and
flaps D and D of a spring F arranged to keep said flaps in closed position
substantially as described.
3. In a photographic printing frame the use of indices arranged with spring
index pointers or fingers J and J working in grooves G and G₁ substantially as
described and used for the purpose specified.
