Improvements in Racks used for Soaking or Drying Photographic
Plates.
I JOSIAH PUMPHREY of 160 Angelina Street in the City of Birmingham
Manufacturer do hereby declare the nature of this invention to be as follows:-
I construct a frame and hinge on it in a suitable position two corrugated plates,
furnished with feet each having a fence on one side; handles are attached to the
upper edges of the corrugated plates, the measurements are so calculated that in
one position the corrugated plates are at such a distance as to take plates of a
required size between them & by reversing the apparatus the same number of a
dissimilar size are equally well accommodated without any readjustment of loose or
fixed parts.

Improvements in Racks used for Soaking or Drying Photographic
Plates.
I JOSIAH PUMPHREY of 160 Angelina Street, in the City of Birmingham, in
the County of Warwick, Manufacturer, 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 has for its object improvements in racks used for soaking or drying
photographic plates by which I obtain a rack which can be readily converted into
the requisite form for receiving either one or the other of two or more different
sizes of plates such as and plate or and 5" x 4" or any other combination of
sizes the whole also folding up into compact form for storage & transit while at the
same time my improved rack is simple cheap and most effective in use.
I construct a frame and hinge on it in a suitable position two corrugated plates
furnished with feet each having a fence on one side handles are attached to the
upper edges of the corrugated plates the measurements are so calculated that in one
position the corrugated plates are at such a distance as to take plates of a requisite
size between then and by reversing the apparatus the same number of a dissimilar
size are equally well accommodated without any readjustment of loose or fixed
parts.
In order that my invention may be clearly understood and more easily carried
into practice I have appended hereunto a sheet of drawings upon which I have
fully illustrated the nature of my said improvements.
Figure 1 is view of one of my racks shewn in position for receiving the larger
size of plates.
Figure 2 is a view of the same rack altered to receive the smaller size of plate.
Figure 3 is a view of the same rack when folded up.
Figure 4 is a diagram shewing the which a third size of plates may be accom-
modated in one of my racks.
Figure 6 shows another arrangement by which a third size of plates may be
accommodated in the racks.
In carrying my invention into effect I form my rack with the wire frame A upon
which I hinge the two corrugated plates B and B¹ the plates being attached to the
sides 6 having the feet which form the hinges upon which the corrugated plates

plates are turned through the frame A as shewn by diagram Figure 4 to stand
up at right angles in one direction the sides are at the requisite distance apart
to accommodate the larger sized plates P as shewn by Figure while upon the
corrugated ends B and B' being turned through the frame and set up in the reverse
position as shewn by Figure 2 the rack is in position to receive the smaller
plates P while for packing and transport it is only necessary to fold down the
corrugated plates as shewn by Figure 3.
For accommodating a third or smaller size of plate in the same rack I may
provide the corrugated slip D having the hook ends which hook upon the
frame A and which thus forms a platform upon which a base for the plates P²
rest, the plate being retained in a perpendicular position by one of its sides
engaging with the corrugated plate end B as shewn by Figure 5 or I may
effect the same object by hanging a strip of corrugated metal E upon one of
the corrugated ends B₁ the supports of the strip being so shaped as to cause the
strip E to stand out or project from the end B' and thus the space between
the end B and strip E is made just sufficient to accommodate a smaller sized
plate P³. Of course I may vary the details of my invention without departing
from the nature of the same and the distances between the corrugated ends may
be arranged as to take both the short side of a large plate and the long side of a
small plate on each side thus one rack serving as a receptacle of four or more
different sized plates.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
1st. In racks used for soaking and drying photographic plates the corrugated
ends or plates B and B eccentrically mounted on the frame A substantially
such as and for the purpose herein set forth and shewn upon the drawings.
2nd. The improvements in racks used for soaking or drying photographic plates
substantially as and for the purpose herein set forth and shewn upon the accom-
panying sheet of drawings.
Dated this Seventh day of June 1893.
