page_text: PROVISIONAL SPECIFICATION left by George Davies at the Office of
the Commissioners of Patents, with his Petition, on the 29th
August 1878.-A communication from abroad by Madame Nathalic
de Saumery, of Orléans, France.
I, GEORGE DAVIES, of Manchester, in the County of Lancaster, Civil
Engineer and Patent Agent, do hereby declare the nature of the said
Invention for "IMPROVED APPARATUS TO BE USED IN THE MANUFACTURE OF
FESTOONED EDGING OR TRIMMING," (a communication to me from abroad by
Madame Nathalie de Saumery, of Orléans, France), to be as follows:-
This Invention relates to improvements upon the subject-matter of
Letters Patent granted to William Olarke, dated May 24th 1864,
No. 1294, for "Improvements in Apparatus for the Manufacture of
Festooned Edging or Trimming," (a communication from Henri
Francois Timothée] Mégraud, of Paris), the particular apparatus to
which the present Invention applies being the stamping machine first
described in the Specification of the said Letters Patent.

page_text: .
In the machine or apparatus, above referred to, the stamping or
cutting out of the strip of gummed fabric, previous to covering the same
with satin stitch, is performed by means of a stamp or cutter, which
rises and falls at intervals as the gummed strip passes beneath; and the
principal feature of the present Invention consists in the substitution
of a revolving knife or cutter for the reciprocating stamp employed in
the former apparatus, by which means the action is rendered continuous
and a great saving of time is effected.
The revolving knife or cutter is mounted in a frame which is capable
of sliding vertically in grooves in the side frames of the machine, and
is pressed into contact with a bed roller by means of a fly wheel and
screw, a spring being interposed for the purpose of giving a certain
amount of elasticity.
The bed roller is mounted on the main spindle or shaft of the machine
(which is either driven by power or turned by hand), and is provided
with a circumferential groove, into which tin is run to prevent the
edge of the knife from becoming dull by cutting. The surface of the
tin can be renewed at any time by turning it against a small chisel,
and when it becomes too far worn it is easily replaced by a fresh ring
of tin.
The strip of ground material to be cut is wound upon a drum and
the end drawn through a guide, which at the same time regulates
the pressure or tension and guides it between the cutter and the bed
roller. The strip thus cut to the desired form then passes through a
second guide, and is wound on to a bobbin or roller mounted on a
spindle driven by a band from the main shaft of the machine.
-
The knives or cutters are made with plain, undulating, or indented,
edges, according to the pattern to be cut, and an infinite variety of
forms of knives being provided, onc is substituted for the other at will,
according to the work to be produced. The gummed strips thus cut
(whether straight, undulated, or indented) are then passed through the
satin stitch or embroidering machine, described in the Specification of
the Letters Patent before referred to, and covered with cotton, wool,
silk, or gold thread, and are then sewn by hand on the fabric to be

ornaments in exact imitation of embroidery by hand, and at a very
considerably reduced cost.
