I. WILLIAM EDWARD GEDGE, of the Firm of John Gedge and Son, of
No. 11, Wellington Street, Strand, in the County of Middlesex, Patent
Agent, do hereby declare the nature of the said Invention for "AN IMPROVED
MARQUETRY OR VENEER SAW, AND MACHINERY OR APPARATUS CONNECTED THERE-
WITH," (a communication to me from abroad by François Marie Gustave
Raymond, Baron de Roverié de Cabrières, of No. 15, Passage des Petites
Ecuries, Paris, France,) to be as follows:-
The apparatus which forms the object of this Invention consists of a
marquetry or veneer saw or veneering web advantageously arranged for
boring or drilling, turning and sharpening. The saw is composed of five
principal parts, which aro,-a fly wheel fixed on a horizontal shaft resting on
two vertical uprights; a large wheel fixed also on a horizontal shaft, bent at
one of its extremities to form a crank, the whole surmounted by two vertical
uprights more elevated than the fly wheel; a moveable wooden plate or bed;
and, lastly, a wooden pedal. The blade of the saw is about five-and-a-half
inches in its entire length, about four inches of which is toothed. The teeth
which are in form of a triangle without any setting or edging, project about
the fiftieth part of an inch, and are about the twenty-fifth part of an inch

page_text: apart, which is also the entire breadth of the blade. When this apparatus is
to be used it must first be ascertained whether the blade of the saw is sharp
and clean, then pass along it a feather slightly steeped in olive oil. These
precautions taken and the operator seated on a small chair opposite the table,
he places with one hand on the moveable plate the small board which he
intends to cut, while with the other hand he will seize beneath the said
moveable plate a quadrangular tube, which passes through the lower bars or
fitting of the saw blade, taking care not to abandon his hold while the instru-
ment is working; this done the operator will give a progressively rapid
movement to the pedal until the apparatus has attained its maximum speed,
taking care that his foot absolutely follows the stroke of the pedal, so as to
stretch the saw blade to the uttermost; it is then that he presents to the saw
blade the board to be cut, so that it may be begun at the desired point. The
saw blade once entered on the line of the design previously traced on the
board the operator continues to drive the machine, taking care to accelerate
its motion when he wishes to suddenly alter the direction of the saw. When
it is desired to bore a piece of metal, the spot where the hole is to be made
will first be marked with a hammer and punch, which being done the two
parts of the carriage are brought together by pushing them with the hand
until the piece to be bored or drilled is held by the pressure on one part, and
the point of the drill on the other. The piece to be drilled is then fixed by
two claws, and the operator will but have to set the machine at work with his
right foot, while with the left hand he acts on a large screw to alternately
advance and retire the part on which the piece to be drilled is placed. This
instrument although specially intended for delicate work may be made on a
larger scale, and used for ebenistry and carpenters' work.
