Year: 1869

page_text: PROVISIONAL SPECIFICATION left by William Edward Gedge at
the Office of the Commissioners of Patents, with his Petition, on
the 21st December 1869.-A communication from abroad by Jean
Baptiste Bourge, Machinist, and Jean Baptiste Lefebvre, Comb
Manufacturer, both of 37, Boulevard Bonne Nouvelle, Paris,
France.
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
"IMPROVED MACHINERY FOR SHEARING AND CLEANSING WOVEN FABRICS," a
communication to me from abroad by Jean Baptiste Bourge, Machinist,
and Jean Baptiste Lefebvre, Comb Manufacturer, both of 37, Boulevard
Bonne Nouvelle, Paris, France, to be as follows:-
The apparatus shewn or illustrated by the Drawings annexed to this
Provisional Specification is destined for shearing and cleansing such
fabrics as are susceptible of undergoing both these operations, such as
cloths, merinos, calicos, silk, stuffs, or flannels. Fine and light stuffs

page_text: may be operated on, it being sufficient to pass these stuffs once through
the machine to obtain a result which leaves nothing to be desired.
The principle of this apparatus or machine consists in a plane,
hollowed in its interior in form of a widened mortice, the narrowest
opening of which receives two steel blades intended to operate on the
fabrics, these blades present a straight and sharp toothing in chisel form
in the interior. The come-and-go motion of the plane is circular. The
pivots of the supports of the batten are placed one on the summit of
the machine. the other below.
Figs. 1, 2, 3, and 4 (Sheets 1 and 2 of the annexed Drawings)
represent different views of the improved machine so arranged as to
shear and cleanse the two sides of the stuff at one operation. The piece
of stuff Y passes on a bar D to arrive on the rollers E, E, in order to
obtain the necessary tension according to the resistance occasioned by
the combs or planes, thence on to the other bar F on the comb or
plane G, which shears it on one side on a bar H under the plane or
comb I, which shears at this part to the bar J on the roller K, and
finally on the cylinder L on which rolls the sheared and cleansed
stuff.
The parts of the machine invented and added to the loom usually
used, that is to say, to the loom which works horizontally, are the
following:-B', straps imposing on the planes or combs a circular
motion. C¹, C", connecting bars giving also circular motion to the
combs; the connecting bars are fixed on the supports of the batten N, 2
at the extremities of which are two studs or pins turning in the bearers
or journals M fixed on the uprights or standards O, O, and on the
bar T. P, a stud or pin of the guide Q which communicates the come-
and-go motion to the planes or combs G and. I. R, batten connecting
the bars C¹, C. This machine is put in motion by means of a crank or
handle S. To move it by steam the handle or crank is to be replaced.
by pullies.
The parts 5, 6, 7, 8, and 9 shew the regulating or manual system,
that is to say, one by which a man may put the machine in full operation
without the help of a crank or handle.

page_text: Summary. The various systems of shearing and cleansing machines
known or used up to this date operate by horizontal motion, while the
batten system herein-before set forth operates in a circular manner.
In the first case the stuff or fabric is often torn, which never occurs in
the second, and this system is therefore an important improvement.
