Improvements in Heald and Shuttle-box Operating Mechanisms, and
in the Construction of Shuttle-boxes Applicable for Looms for
Weaving:.
We RICHARD LONGDEN HATTERSLEY of Keighley in the County of York, Machine
Maker, aud JAMES HILL of the same place, Manager, do hereby declare the nature
of this invention to be as follows, that is to say :-
i
It relates firstly to improvements in heald operating mechanisms applicable for
looms for weaving and consists of arranging, forming and constructing certain parts
in and in connection with that class of heald operating mechanism well known, as
"Hattersley's positive," or "Hattersley's-non-positive" dobby, in such a manner that
better facilities are afforded for the operative to examine the healds as is from time
to time necessary, as well as rendering said certain parts more firm or stable than
heretofore..
The object of this invention is attained by arranging the dobby, of the class above
referred to, so that it's upwardly extending lever-arms may be joined to suitably
formed pendent levers which are mounted upon a shaft carried by suitable bearings
formed on the gauntrys which support the well known series of bowls over which the
heald operating cords pass. To these pendent levers are coupled the said operating
cords by means of any of the well known kinds of connecting parts.
The desired variation in the distance or space that the healds have to be operated
so as to produce a proper shed or opening for the passage, of the shuttle as is well
understood is obtained by varying the distances of the coupling pins from the
centres of their respective pendent levers.
These pendent levers are made detachable from the shaft upon which they are
mounted so that each or any one of said levers may be removed without displacing
any of the others.
When the positive dobby", is the one made use of, a supplementary arm is
attached to each of the levers therein which have their usual arms extending
vertically, and these supplementary arms are made to extend somewhat horizontally,
outwardly from the loom and underneath the outer parts forming the said dobby.
To the supplementary arms are attached, by means of suitable intervening levers
and connecting rods and cords, the lower edges of the healds for the well known
purposes.
By the arrangement of the said 'supplementary arms as above described, the
positions of the herein before described pendent levers is not interfered with, and
again' by this arrangement' the connecting rods, which couple the dobby by the
other intervening parts to lower edges of the healds, are placed on the outside of
the end frame of the loom, thereby not in any way interfering with, so as to diminish,
the space for the warp'in said loom...
F
Appropriate supports for the several parts and mechanisms above described are
employed, which render same firm or stable and yet said supports are so distributed
as to leave free and open 'access to the healds.
The second part of our invention' relates to improvements in the construction of
shuttle-boxes of the well known class wherein there are several or a series of boxes
all of which are arranged to be parallel to each other and to be in the same plane,
and said improvements consist of so constructing and arranging the parts which form
said boxes, that they may be readily and securely joined together and when so
joined may form lighter and more substantial boxes than have heretofore been

page_text: This is attained by forming the holding or stay pieces (which bind the several
shelves, forming the divisions in the series of boxes, together) to have suitable
openings to allow the insertion of certain projecting parts formed upon the (said)
shelves, said shelves being of sheet metal and of an appropriate form.
These projecting parts are bent so as to be at a suitable angle to the shelves, and
so that when they are inserted into the openings in, and attached by rivets to the
binding pieces, said pieces and said shelves will be joined together in an appropriate
manner to form the shuttle boxes.
-
Instead of the binding pieces having projections formed on or attached to them
for the purpose of supporting or affording means for mounting the parts, well known
as the swellers," upon, the shelves have the necessary projecting parts formed upon
them for this purpose.
Similar projections for mounting the guide pieces, for the swellers upon, are also
formed on the shelves.
Again projecting pieces are formed on said shelves, to enter openings and be
rivetted to another stay piece which in an ordinary way forms the frontal shield for
the series of boxes.
The third part of this invention relates to improvements in certain parts forming
that class of shuttle-box operating mechanism wherein cranks or swapes are employed
for effecting the changes in position of the box operating levers, and consists of so
forming these parts that the adjustment of the shuttle boxes is greatly facilitated.
This is attained by forming the crank pin adjustable, its adjustment being effected
by means of an additional screw which is arranged to regulate the distance, at
which said pin is retained, from the centre of its bearings or from its centre of
motion.
By these means of adjustment the very finest degree of variation in the movements
of the box-operating levers may be obtained, without the detachment of a single
part.

Improvements in Heald and Shuttle box Operating Mechanisms, and
in the Construction of Shuttle-boxes Applicable for Looms for
Weaving.
We, RICHARD LONGDEN HATTERSLEY of Keighley in the County of York, Machine
Maker, and JAMES HILL of the same place, Manager do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, that is to say:
It relates firstly to improvements in heald operating mechanisms applicable for
looms for weaving and consists of arranging, forming and constructing certain parts
in and used in connection with that class of heald operating mechanism well known
as "Hattersley's positive" as also " Hattersley's non-positive" dobby, in such a
manner that better facilities are afforded for the operative to examine the healds as
is from time to time necessary, as well as rendering said certain parts more firm or
stable than heretofore.
The second part of this invention relates to improvements in the construction of
shuttle-boxes of the well known class wherein, there are several or a series of com-
partments all of which are arranged to be parallel to each other and to be in the
same plane, and said improvements consist; of so constructing and arranging the
parts which form said boxes, that they may be readily and securely joined together
and when so joined may form lighter and more substantial boxes than have heretofore
been produced.

page_text: The third part of this invention relates to improvements in certain parts forming
that class of shuttle-box operating mechanism wherein cranks are employed for
effecting the changes in position of the box operating levers, and consists of so
forming these said parts that the adjustment of the shuttle-boxes is greatly
facilitated.
Hereunto appended are sheets of drawings illustrative of our invention, fig. 1 of
which is front elevation of a sufficient portion of a loom to show the application of
our improvements.
Figs. 2, 3, 4 and 5 are top, front, back and end views, respectively, of our improved
formation or construction of shuttle-boxes.
Figs. 6, 7, 8 and 9 are detail drawings of parts used in the construction of the
shuttle-box as hereinafter explained.
Figs. 10 and 11 are side and top views illustrative of our improved box-operating
mechanism-Figs. 12 and 13 are detail drawings of parts used in the box operating
mechanism.
Similar letters and figures of reference indicate similar parts throughout; the
several views.
We attain the object of the first part of our invention by arranging the dobby so
that its upwardly extending lever-arms a may be joined, as by rods a², to suitably
formed pendent levers 6 that are mounted upon a shaft c carried by the bearings d
formed on the gauntrys e that support the well known series of bowls f and fover
which the heald operating cords g and gl pass to be coupled or attached to the healds h.
The cords g and g' are attached to the levers 5 by any of the well known means at
present in use.
The desired variation in the distance or space that the healds have to be operated
according to their respective positions with the front of the loom, so as to produce a
proper shed or opening for the passage of the shuttle by those of said healds whose
positions approach the rear of the loom being made to move through a greater space
as is well understood, is obtained by varying the distances of the coupling pins b₁
(shewn in broken lines) from the centres c¹ of their respective pendent levers b.
The levers are made detachable (by having the lateral opening 62 formed therein,
as also the slot 6%, fig. 1 A, to span the bolt 6 in order to be kept thereby in position,
said bolt 6 being detachable without interfering in any way with any of said levers 6)
from the shaft c upon which they are mounted so that each or any one of said levers
may be removed without displacing any of the others.
As will be seen the hereinbefore described arrangement is applicable alike for the
"non-positive" as the "positive" dobby, however when the latter is made use of, in
addition to the above described arrangement of parts, we attach the arms a¹ to the
levers having arins a.
C
"
These arms a' are made to extend outwardly from the loom and beneath the other
parts forming the dobby, are by the rods k, k¹ and 2 and the levers and l
and the cords or other couplings, attached to the lower edges of the healds h for
the well known purposes of effecting their downward movement." eqniv.
By the arrangement of the arms as described, for the purpose of effecting the
downward movement of the healds h or that reverse to the movement imparted to
said healds h by the other arm a, the position of the pendent levers b is not interfered
with, and again by this arrangement the connecting rods k are placed on the outside
of the end frame A of the loom, thereby, not in any way interfering with so as to
diminish the space for the warp in said loom.
In order to meet the variation in the movements of the healds h caused by that of
the position of the pins bas herein before described, the distances of the pins in the
levers from the centres are made variable as shewn by fig. i.
24
The supports m which form bearances for the dobby are employed, by being of the
form shewn, for supporting the levers l.
By the arrangement and formation of the supports m, the gauntrys e, the end
frames A and A, the stays n and n, the supports o o' for the shaft p, and the

page_text: stays p' and p³ as illustrated, the whole of the framework for supporting the dobby
is rendered most firm and stable, and yet by the stays p' and på being arranged as
shewn they are brought well within the lateral space of the end frames A A' and so
do ot interfere with, but allow free and open access to the healds h.
The object of the second part of our invention is attained by forming the holding
or stay pieces s and (which bind the several shelves t, forming the divisions in the
series of boxes, together) to have suitable openings (fig. 6) to allow the insertion
of certain projecting parts t (figs. 7 and 9) formed upon the shelves t, said shelves t
being formed of sheet metal aud of an appropriate form or configuration, as shewn
by figs. 7 and 9.
These projecting parts t¹ are bent so as to be at a suitable angle to the shelves t (see
figs. 7 and 9) and so that when they are inserted into the openings s' in, and attached
by (rivets or) small set screws it to the binding or stay pieces 8 and 82, said
pieces sand and said shelves will be joined together in an appropriate manner to
form the shuttle-box of the desired number of compartments v.
Instead of the stay pieces 8 or 82 having projections formed on or attached to them
for the purpose of supporting or affording means for mounting the parts v¹ upon
(said parts v¹ being well known as the "swellers") the shelves t have the necessary
projecting parts formed upon them for this purpose. Projections are also
formed on the shelves t so as to afford support or attachment for the swellers' guide
pieces »²
Again projections t are formed on shelves t, to enter openings and be rivetted
to another stay piece 8 which in an ordinary way forms the frontal shield for the
series of compartments forming the shuttle-boxes.
From the foregoing it will be seen that by the improved formations of the varied
parts forming a complete series of boxes as above described, the shelves & which
have in most cases heretofore been merely employed as partitions to form the series
of shuttle-boxes, are now employed to perform an important part in withstanding
all or any of the forces acting upon or through the shuttle-boxes, in this manner
much of the superfluous material heretofore employed in the construction of shuttle-
boxes is entirely dispensed with.
Respecting the third part of this invention we attain the object desired by forming
the crank pin w adjustable, its adjustment being effected by means of an additional
screw w¹ which is arranged to regulate the distance at which said pin w is retained
from the centre x of its support or bearance or from its centre of motion.
.
By these means of adjustment the very finest degree of variation in the movements
of the box operating levers y and y¹ may be obtained, without the detachment of a
single part, the only requirement being that the nut z should be slightly unscrewed
or slackened to allow the necessary regulating movements of the screw w' after which
it is again to be tightly screwed up and the whole is ready for operating
efficiently.
