Morgan at the Office of the Commissioners of Patents, with their
Petition, on the 22nd January 1857.
We, ELISHA MANDER, Photographic Case Manufacturer, of Birmingham,
and WILLIAM MORGAN, Manufacturer, of the same Place, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN THE MANUFACTURE OF
PHOTOGRAPHIC, JEWELLERS', AND OTHER CASES HAVING WOOD OR PAPIER MACHE
FOUNDATIONS, AND WHERE RAISED, REGULAR, OR IRREGULAR FORMS ARE REQUIRED
IN SUCH CASES, AND THE MACHINERY FOR CARRYING OUT SUCH IMPROVEMENTS,
PARTS OF WHICH ARE APPLICABLE TO OTHER PURPOSES WHERE SAWING OR SHAPING
IS REQUIRED," to be as follows:-
Our improvements consist in the method of mitring the angles in double
mitres, so as either to retain the fibre of the material or not to forin the two
mitres at one operation.
In cutting up the material with mitred edges without waste by reversing
the same in a suitable sawing machine.
In the gluing into tubes and holding of the material so prepared in tubes
suitably arranged instead of tying or screwing such parts together.
In the cutting of such tubes into rings of widths to form the top and bottom
of cases, either together or separately, by a combination of saws placed at the
required distances.
In the mode of preventing warping in wood cases by gluing two thicknesses
of board together, the grain of the wood in such boards running trausversely.

page_text: In the combination of papier mâche or millboard tops and bottoms with
wood sides, and the employment of marine glue when necessary.
In the mode of rounding and forming the tops, bottoms, or interior fittings
of cases by means of a machine for that purpose, herein-after to be described,
also by vertical or horizontal cutters, or by circular planes running upon a
spindle.
In the forming of the tops or bottoms of cases out of one piece, either of
single boards or other material, or double boards placed transversely by cutting
the same with double mitres, taking out the corner pieces, and turning down
the exterior portion to form the sides, placing the same when glued in hot
moulds suitably arranged in tubes or otherwise to give the proper form to
the tops and bottoms.
In the employment of composition or glue, or marine glue with sawdust, in
hot moulds, to form cases.
The sawing machine is made with a circular or other saw placed at an
angle of 45 degrees to the table, and is made to traverse by suitable con-
trivances, the material being held stationary in guides, or the saw may be
stationary and the material moving against it.
The shaping of the various portions of cases is performed by a machine,
having two lathe heads geared together and arranged either side by side or
facing each other, one having an arrangement for holding the material to be
cut, and the other a maundril corresponding with or the reverse of the form
required, the cutter running in a rocking shaft or spring slide placed on a slide
passing before or between such heads; or a single head may be used, the
maundril being placed on the spindle of the said head; or the action may be
reversed, the head may be made to rock instead of the cutter.
Both these machines for sawing and shaping are applicable to other
purposes where such operations are required.
