PROVISIONAL SPECIFICATION.
An Improved Gauge for Centering and Mounting Photographio
Prints and the like.
I, CHARLES FULTHORTE GOOCH, of Campville, Cathedral Road, Cardiff, in
the County of Glamorgan, Civil Engineer, do hereby declare the nature of this
invention to be as follows:-
(
The object of this invention is to provide an improved means for marking the
position on card-board mounts and the like for their photographic and other
prints.
At present as far as I am aware, no mechanical method for accurately and
quickly measuring and indicating such position on the mount is in use.
My invention consists principally of a pair of sliding rectangular gauges of
sufficient length to mark the largest cards that may be required. Each of these
gauges is marked from a zero point at each end, and to a distance back, for the
entire or any length necessary. These indications are, preferably, marked at each
half inch being again subdivided, half-inch distances, preferably, into thirty
seconds, or any other suitable subdivision may be employed.
The outer side of one of the gauges is divided, for its entire length, into
one-inch distances each inch being again subdivided into sixteenths, these being, as
will be seen, the duplicates of the scales upon the other sides of the gauge. At
the zero point, a sliding clip is attached, adapted to hold a sharp pointed pencil
or marker. The point of the pencil is supposed always to be at the zero point,
and the object of the sliding clip is to facilitate its perfect accuracy.
Sliding along the two gauges, is a metallic or other tubular clip of rectangular
shape, so that the gauges may slide freely within. A suitable spring or other
means of tightening the said sliding tubular clip may be employed. On the under
side of this clip, or on the same side as the point of the pencil is placed is a
projection suitably formed to act as a gauge.
This projection can be of any convenient length or width or form necessary to
ensure the gauge being held square with the card.
When a photograph or print is to be mounted, the picture is first measured on
the inch scale, in either direction, and the reading thereby obtained is marked off
on the half inch scale on the back of the gauge to which the pencil is attached,
which will of course be half the size of the picture. The mounting board is then
measured on the inch scale and the sliding tubular clip adjusted to the same reading
on the upper half-inch scale.
The gauge is next taken in the hand and the position thereby obtained marked
off very much after the manner of a carpenter's marking gauge. The other
dimensions of the picture are taken in a similar way.
The mount being thus accurately measured and marked, the print is laid to the
lines and pasted down in the usual way.

An Improved Gauge for Centering and Mounting Photographic
Prints and the like.
I, CHARLES FULTHORTE GOOCHI, of Campville, Cathedral Road, Cardiff, in
the County of Glamorgan, Civil Engineer, 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 :-
My invention relates to improvements in gauges for marking out upon a mount,
the exact central position thereon which the photograph or other print or the like
to be mounted, will occupy.
It consists in the combination of two straight edges held together by any device
adapted to provide for their sliding longitudinally in or upon each other; a
measuring scale on one of them; a second scale, half the size of the measuring
scale, likewise on the said straight edge; and on the other straight edge, a third
scale being a duplicate of the last mentioned one.
In order that my invention, and the means by which it is to be carried into
practical effect, may be thoroughly understood, I will now describe it and them in
detail, referring in so doing to the accompanying figures which are to be taken as
part of this Specification and read therewith.
Figure is a plan of a marking gauge made according to
invention.
D
Figure 2 is a perspective view illustrating the use of the gauge.
Figure 3 is an inverted plan corresponding with Figure 1.
Figure 4 is a side elevation of Figure 1.
the present
Figures 5 and 6 are, respectively, inverted plan and plan of a modification of
the scale illustrated in the previous figures.
Referring to Figures 1 to 4, a is a straight edge. a' is a measuring scale of
inches. is a second straight edge, preferably of the same width and thickness
and about the same length as the straight edge a. The two are held together,
preferably one upon the other, by a pair of loops c, c¹ in such a way that either
can be moved along its fellow. No importance is attached to the details of the
device by which the two straight edges are held together, and provided that it
allows of the longitudinal motion above mentioned, the device in question may be
of any type.
d is the marker. It may be of any convenient construction and held to the
straight edge in any convenient way. It is shewn as being a lead pencil adjustable
vertically in a split socket d' by means of a set screw d², both socket and set
screw being carried by a detachable loop or clip which can be held to the
straight edge by a set screw d. The marker d may be either pointed or chisel
edged, as may be preferred. Where it presents itself beyond the surface of the
straight edge, a is the zero of the measuring scale. This as well as the other
scales described further on are shewn as set out upon the flat sides of the straight
edges, but only because that is the most convenient and suitable position for
them.
The measuring scale al is set out in inches along the straight edge a from zero
towards the opposite end of it as far as may be desired. Any other unit of
measurement may be adopted. a² is a second scale. It is set out on the same
straight edge a as the scale a' and in the same direction, but preferably on the
opposite face of it. Its zero coincides with that of the last mentioned scale. The
scale a is always half that of the scale a'. This proportion is a distinguishing
feature of the present invention, as will appear more clearly further on. As,
therefore, the scale a¹ is one of inches, a' is a half inch scale. is the third
scale. It is a duplicate in all respects of the scale a² and is set out along the

page_text: preferably outer flat side of the straight edge b in the same direction as the others.
Its zero coincides with the end 6 of the straight edge in order that the
coincidence of the said zero with any reading on the scale a² may be distinctly
perceptible.
e is a guide adapted to slide along the straight edges in either direction. It is
provided for the purpose of guiding the marker d in a line parallel with the edge
of the mount. For this reason, its working face stands transversely across and.
projects from the straight edges and is also made fast to the loop c (the one next
to the marker). is the print to be mounted, and g is the mount.
A gauge made according to the present invention is used as follows. One of
the dimensions-say, the width of the print f is ascertained by measuring it with
the measuring scale a'. The zero of the scale is pushed along the straight
edge a np to the reading on the scale a² which corresponds with the width as
ascertained by the use of the measuring scale a¹. Assuming that this width is.
1inches, the zero of the scale 61 will stand in the position illustrated in Figure 1.
The actual width of the mount g is next ascertained by means of the measuring
scale a', and the guide e pushed along the scale 6 until its working face coincides
with the corresponding reading on the said scale a². If the width in question is
8 inches, the guide e will stand with its face el in the position illustrated in
Figure 1. The distance between the said face e¹ and the pointer is equal to the
width of the mount less one side margin of the mount, or, in other words, to the
width of the print plus one side margin of the mount, because in any case
the width of such margin is always the full width of the mount less half the
combined widths of the mount and print. Hence the relationship between each of
the scales a², 6' on the one hand, and the scale a' on the other, as well as that
between the two scales a² and b².
The lines ff are then drawn along the mount by applying the gauge to it in
the well-known way-see Figure 2.
The widths of the top and bottom margins are next found in the way described
above, and the lines g¹,
drawn.
Referring to the modification illustrated in Figures 5 and 6, the straight edge b
slides in a groove in the straight edge a. The marker d and its addenda, as well
as one loop c―the one farthest from it-are dispensed with.
The three scales are not confined to the respective positions illustrated. They
may occupy any others provided that their respective utilities are not interfered
with.
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. The herein before described combination of two straight edges held together
by any device adapted to provide for their sliding longitudinally in or upon each
other; a measuring scale on one of them; a second scale half the size of the said
measuring scale, on the same straight edge; and on the other straight edge, a third
scale, being a duplicate of the last mentioned one, as set forth.
2. The hereinbefore described device for ascertaining a dimension, recording one
half of it, and adding to it the half of another dimension.
