IMPROVEMENTS IN PACKING PHOTOGRAPHIC PLATES, AND IN APPLIANCES TO BE USED IN SUCH PACKING
Year: 1880

page_text: LETTERS PATENT to Benjamin Joseph Edwards, of 6, The Grove, Hackney,
in the County of Middlesex, for an Invention of "IMPROVEMENTS IN PACKING
PHOTOGRAPHIC PLATES, AND IN APPLIANCES TO BE USED IN SUCH PACKING."
PROVISIONAL SPECIFICATION left by the said Benjamin Joseph Edwards
at the Office of the Commissioners of Patents on the 15th April 1880.
BENJAMIN JOSEPH EDWARDS, of G, the Grove, Hackney, in the County of
Middlesex. "IMPROVEMENTS IN PACKING PHOTOGRAPHIC PLATES, AND IN
APPLIANCES TO BE USED IN SUCH PACKING."
This Invention relates to an improved method of packing photographic plates,
and to improved appliances for protecting the films upon such plates from light
and injury and preserving the plates themselves from breakage.
In order to carry out my Invention I make a rectangular box of cardboard,
pasteboard, wood, or other suitable material, of sufficient capacity to contain tho
plates, and to two of the sides of the interior of the box I attach or adjust pieces of
paper or other suitable flexible material, folded or corrugated, so as to form ridges
projecting internally from the two sides of the box, and I make these projections
or ridges of a convenient depth and of any suitable width apart in proportion to
the thickness of the glass plates, the number of such ridges or grooves being made
to correspond with the number of plates the box is designed to contain.
In order to use the box for packing photographic plates I slide the plates
separately into the box in such manner that each of the two ends of the plate
passes into one of the grooves formned by the folded or corrugated paper attached
or adjusted to the sides of the box, the ridges or tongues of the folded paper pro-
jecting between the plates, and keeping then slightly apart so as to prevent injury
to the films upon such plates by abrasion or contact with each other; and I close
the box with a suitable cover or lid, which I make to slide on, so as to exclude
light and air, or the lid may be attached to the box in the ordinary manner.
The ridges or grooves above described serve not only to separate the plates and
keep them from contact with each other, but the tongues or ridges being made
of a yielding or flexible material also tend to prevent breakage of the plates
themselves.
Also this method of packing will allow one or more of the plates to be removed
or replaced without injuring or disturbing others that may remain in the box.

This Invention relates to an improved method of packing photographic plates,
and to improved appliances for protecting the films upon such plates from light
and injury, and preserving the plates themselves from breakage.
In order to carry out my Invention I make a rectangular box of cardboard,
pasteboard, wood, or other suitable material, of sufficient capacity to contain the
plates, and to two of the sides of the interior of the box I attach or adjust piecos
of paper or other suitable flexible material, folded or corrugated, so as to form
ridges projecting internally from the two sides of the box, and I make theso pro-
jections or ridges of a convenient depth and of any suitable width apart in
proportion to the thickness of the glass plates, the number of such ridges or
grooves being made to correspond with the number of plates the box is designed
to contain.
In order to use the box for packing photographic plates I slide the plates
separately into the box in such manner that each of the two ends of the plate"
passes into one of the grooves formed by the folded or corrugated paper attached
or adjusted to the sides of the box, the ridges or tongues of the folded paper
projecting between the plates and keeping them slightly apart, so as to prevent
injury to the films upon such plates by abrasion or contact with each other;
and I close the box with a suitable cover or lid, which I make to slide on, so as
to exclude light and air, or the lid may be attached to the box by hinges in the
ordinary manner.
Sometimes I make the grooves or corrugations of sufficient width to carry two
plates in each groove, the plates being placed back to back to avoid injury to their
prepared surfaces.
The ridges or grooves above described serve not only to separate the plates and
keep them from contact with each other, but the tongues or ridges being made
of a yielding or flexible material also tend to prevent breakage of the plates
themselves.
Also this method of packing will allow one or more of the plates to be removed
or replaced without injuring or disturbing others that may remain in the box.
In witness whereof, I, the said Benjamin Joseph Edwards, have hereunto set
my hand and seal, this Thirtieth day of October, in the year of our Lord
One thousand eight hundred and eighty.
