PROVISIONAL SPECIFICATION.
Improvements in Photographic Printing Frames.
I, FREDERICK TAYLOR, of 16, St. Petersgate, Stockport, in the County of
Chester, Photographer, do hereby declare the nature of this invention to be as
follows:-
:--
My invention relates to improvements in photographic printing frames and has
for its object to facilitate the placing onto and removal of the hinged back from
the print without disturbing the saine and to prevent the index finger from
accidently being moved as heretofore has been the case.
To this end I form the edges of the hinged back and the portion of the printing
frame into which it is placed, with bevelled edges which permits of the hinged
back being readily placed unto or removed from the print without disturbing the
same.
In order to prevent the hinged back from disturbing the print when placing the
spring bars in position over the same, I engage or release the free ends of the
spring bars by means of a movable staple or catch. This staple or catch, which if
deemed necessary may be brought under the influence of a spring, permits of
relieving the hinged back and print from the pressure heretofore exerted thereon
by the spring bars on moving the same in or out of position and thus prevents the
hinged back from being moved and the print thereby disturbed.
To prevent the finger of the index, fixed in front of the printing frame, of
changing its position accidently, I form the dial opposite each number with notches,
holes, or indents, and the finger with a suitable projection to enter the said
notches, etc. successively when placed in position.
Dated this 20th day of Anril 1890.
