Year: 1862

page_text: LETTERS PATENT to William Clark, of 53, Chancery Lane, in the County
of Middlesex, Engineer and Patent Agent, for the Invention of "Ix-
PROVEMENTS IN MACHINERY FOR THE MANUFACTURE OF FISHING AND OTHER
NETS. A communication from abroad by Messrs. Felix Marie Baudouin
and Achille Baudouin, Civil Engineers, and Jean Baptiste François
Jouannin, Mechanician, all of 29, Boulevart St. Martin, Paris.
PROVISIONAL SPECIFICATION left by the said William Clark at the
Office of the Commissioners of Patents, with his Petition, on the
24th July 1862.
I, WILLIAM CLARK, of 58, Chancery Lane, in the County of Middlesex,
Engineer and Patent Agent, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINERY FOR THE MANUFACTURE OF FISHING
AND OTHER NETS," to be as follows:-
This Invention relates to a new arrangement of the working parts of the
improved loom for the manufacture of fishing and other nets, which arrange.
ment is a further improvement on those already patented in England, and dated

page_text: Sept. 19th 1861, No. 2340, and which consists in simplifying and reducing
the number of movements and parts intended to operate the tying books.
I will here repeat what has been already described in the English Patent
above referred to, viz., that the hook-carrying box has, in order to imitate the
human hand, four movements, which have since been reduced to three, and
that the hooks have themselves a circular motion. The first movement of
the box is an upward movement, and vice versa; the second movement is
onward and downward; the third movement, from left to right, has been sup-
pressed, and replaced by the displacing of the threads themselves; and the
fourth movement is circular in the vertical direction.
The Specification of the preceding Patent has sufficiently described the
different arrangements of the parts, and I will therefore limit the comparison
here to the parts which have undergone some modification.
Fig. 1 represents a side view of the arrangements of the working parts;
Fig. 2 a partial front elevation, showing a modification in the arrangement
first described in the preceding Patent..
a, hook box turning on the connecting rods b, connected together by a cross
bar c, so as to form a rigid frauie; which receives à forward and backward
motion through the pair of cams d placed on each side of the loom e. .Two
vertical rods jointed on each side to connecting rods b, imparting to them a
downward vertical motion, which motion is by the latter transmitted to the
hook box a; f, pair of cams imparting to the connecting rods / the downward
movement above alluded to. The cams d and fact upon the end of the con-
necting rods, which they operate either on their periphery or in an excentric
groove or channel formed in their surface; 9, cams mounted upon the driving
shaft of the machine; they operate the connecting rod h, which imparts to the
hook box a partial reciprocating rotary motion in the vertical direction. To
this end the connecting rod carries on its end the rack i gearing into a
pinion j, in connection with the hook box. These parts exist in the loon first
herein referred to, and, as may be seen, their positions have merely been
changed.
I will now describe the new position of the series of parts which impart &
circular reciprocating motion to the hook box. This arrangement is shown at
Fig. 8.
k, rol jointed to one of the connecting rods b, it is operated on at one end
by the cam l, set upon one of the cams d, Fig. 2, and on the other end it is
provided with a fork, which engages in the shaft m, in order to impart a
reciprocal to-and-fro movement in the horizontal direction. The shaft carries,

page_text: as may be seen, the internal rack gearing in the pinions of the tying books, so
that the latter may execute their movements. The wheel o communicates
.motion to another wheel q keyed upon the lower shaft r; and the two shafts p
and carry respectively all the cams before alluded to.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Clark in the Great Seal Patent Office on the
21st January 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
CLARK, of 53, Chancery Lane, in the County of Middlesex, Engineer and
Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of July, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Clark, Her special licence that I, the said William
Clark, my executors, administrators, and assigns, or such others as I, the
said William Clark, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for "Iк-
PROVEMENTS IN MACHINERY FOR THE MANUFACTURE OF FISHING AND OTHER NETS,"
a communication to me from abroad by Messrs. Felix Marie Baudouin and
Achille Baudouin, Civil Engineers, and Jean Baptiste François Jouannin,
Mechanician; all of 29, Boulevart St. Martin, Paris, upon the condition (amongst
others) that I, the said William Clark, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same. to
be filed in the Great Seal Patent Office within six calendar months, next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Clark, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following

page_text: statement, reference being had 'to the Sheet of Drawings hereunto annexed
and to the letters and figures marked thereon (that is to say):
:-
This Invention relates to a new arrangement of the working parts of the
improved loom for the manufacture of fishing and other nets, which arrange-
ment is a further improvement on those already patented, and dated September
19th 1861, No. 2340, and which consists in simplifying and reducing the
number of movements and parts intended to operate the tying hooks.
. . I will here repeat what has already been described in the Patent. above
referred to, viz., that the book-carrying box has, in order to imitate the human
band, four movements, which have since been reduced to three, and that the
hooks have themselves a circular motion. The first movement of the box is
in an upward direction, and vice versa; the second movement is from front to
back; the third movement, from left to right, has been suppressed, and
replaced by the displacing of the threads themselves; and the fourth movement
is circular in the vertical direction.
Fig. 1 of the annexed Drawings represents a side view of the improved
arrangements of the working parts of the loom; Fig. 2 shows a back view of
same; Fig. 3 shows a second side view of the loom, while Fig. 4 shows a
front elevation of same. The same letters of reference indicate like parts seen
in different positions.
⚫a, hook box, turning. on the connecting rods 6, placed on each side of the
loom, connected together by a cross bar c, so as to form a rigid frame: 'This
frame receives a backward and forward motion by means of a pair of cams.or
races & placed on each side of the loom. These cams communicate a to-and-
fro motion to the hook box by means of friction rollers fixed at the end of the
two rods b, b, and engaging in the races, and which are thereby brought
towards or carried further from the centre of said cams at the desired' time;
e, e, vertical rods jointed one on each side to rods b, b, for effecting an up-and-
down motion, which is by the latter transmitted to the hook box a; ff, pair of
cams similar to d, for imparting to the connecting rods e the movement above
alluded to; g, cams mounted upon the driving shaft of the machine; they
operate the connecting rod h, which imparts to the 'hook box, a partial recipro-
cating rotary motion in the vertical direction. To this end the connecting
rod / carries on its end the rack i, gearing in a pinion j in connection with the
hook box.

page_text: "CIRCULAR RECIPROCATING MOTION OF THE Hooks.'
This movement is obtained by means of rod k, jointed to one of the con-
necting rods b; it is operated on at one end by a cam / keyed on the driving
sbaft;
the other end is provided with a fork, which engages in the shaft m, in
order to impart a reciprocal to-and-fro motion in the horizontal direction.
This shaft is furnished with an internal rack gearing with the pinions of the
tying hooks, so that the latter may perform their circular movements. These
improved arrangements permit of having but one driving pinion n gearing in
a wheel o keyed upon the upper shaft p. This wheel communicates motion to
another wheel q keyed upon the lower shaft r; one of the cams f is carried by
wheel o, and cam d by wheel q.
In this improved loom I also dispense with the separating reeds, for which
is substituted a roller s grooved throughout its length. Each thread from the
bobbins is wound once round in these grooves, and is guided vertically by them
until taken up by the hooks corresponding to each thread. The displacement
of the threads from right to left is effected by means of toothed gearing t on
the upper shaft p. One of these pinions carries a cam u, which acts at certain
intervals on a friction roller v fixed to the part of the separating reed y.
This pinion only performs half a revolution for every entire revolution of the
machine, in order to effect the right to left movements of part a; the latter
is returned to its original position by means of a spiral spring fixed on the
right-hand side of the loom. The counterbalance weights for bringing back
the beam or rollers after completing each row of stitches, does not always
effect this object perfectly, especially on a change of temperature, or if any
obstacles are met with I remedy this by the application of a friction
mechanism acting in concert with the counterbalance, and which serves to
complete the action of the latter in order to wind the threads with certainty at
a desired time.
This arrangement is represented at Fig. 5 of the Drawings. 1, sector,
keyed on the principal shaft P, which by the rotation of the latter bears at the
required moment on a pulley 2 keyed on the roller shaft s. The coincident
surfaces of the sector and pulley are inclined in such manner that they may be
brought nearer together when worn by a screw 3.
Having described the nature of this Invention and the manner of performing.
the same, I declare that what I claim as the Invention to be protected by the
herein-before in part recited Letters Patent is, the improved machinery for
the manufacture of fishing and other nets, as described and represented in the

page_text: Drawings, which consists in reducing the number of the working parts so as
to render their action more direct, and permitting of grently increasing the
speed at which the machine is driven, and reducing the labour, and con-
sequently the cost, at least one-third; all as herein-before described. I also
claim the friction mechanism,. as and for the purposes last herein described
and represented in the Drawings.
In witness whereof, I, the said William Clark, have hereunto set my
hand and seal, this Sixteenth day of January, in the year of our Lord
One thousand eight hundred and sixty-three.
Witness,
W. G. E. SWINNOCK,
53, Chancery Lane,
