JOHN FLEMING, of Glasgow, in the County of Lanark, North Britain, India-rubber
Stamp Manufacturer. "IMPROVEMENTS IN THE MANUFACTURE OF VULCANISED
INDIA-RUBBER TYPES OR STAMPS, AND IN THE APPARATUS OR APPLIANCES CON-
NECTED THEREWITH."
This Invention has reference to a new or improved mode and means of accurately
setting and holding vulcanised india-rubber or other such like elastic types or
stamps portably and better in regular line on their stampers or pressing blocks or
frames than heretofore, without requiring the troublesome modes and means
hitherto in use for fixing them in grooves, or permanently securing them by glue
or other cement, or by nails, screws, or other equivalent permanent and laborious
incans, which require great care and accuracy on the part of the person setting up
and fixing the type in the face of the stamps.
And the nature and novelty of this Invention or improvements consist in forming
small round, flat, or other shaped holes longitudinally through the rows of letters in
the same line as through the centre, and made at the time the types are being
formed in rectangular sheets or founts of the different sizes and styles of letters;
all so that when the type when cut up out out of these sheets may be simply threaded
like beads on to wires or parallel strips of metal, or it might be cords, filling the
said holes, and then laid and set in flat rows with their wires or rods on to the face
of the stamper or pressing block, the wires of the several rows of india-rubber types
or stamps so set being held at the edges or ends of the stamper or block by holes in
shallow rims, or small elastic screw, or other clamp which would gripe and hold the
wires where they were set, and be easily loosened for removal and replacement of
other india-rubber letters, numbers, trade marks, figures, or stamps, and set and
fixed up again in a few minutes.
One mode of forming the holes in exuct line in these sheet founts of types or
letters and other stamps is by having shallow transverse strips projecting up at the
sides of the moulds or sheets of types, with one or more in the middle between
these, all with holes or recesses equally divided off parallel through them at a
uniform distance from the surface and bottom line of the type, so that when a piece
of prepared india-rubber was placed over the wires or rods and heated and pressed
into the papier mâchê, stucco, or metal mould to form the sheet of type in the usual

the curing hot chamber or or steam oven until the whole sheet was thoroughly vul-
canised, when it would be taken out and cut up into strips of letters, with a wire
or rod in each when narrow, but two or more when broad, which would then be
removed and each letter cut off and placed in its proper alphabetical chamber in
the "fount," ready for being used or set up to form the stamps by threading them
on to the holding wires, all as before stated.
