IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1884

page_text: RICHARD LONGDEN HATTERSLEY, of Keighley, County of York, Machine Maker,
EBENEZER HARTLEY and AQUILA ELLIS, both of Tudor Street Shed, Manchester
Road, Bradford in the same County Manufacturers do hereby declare the nature
of their Invention for IMPROVEMENTS IN LOOMS FOR WEAVING to be as
follows:-
This Invention relates to revolving or circular and rising box looms, and consists
of an improved arrangement of apparatus for adjusting the shuttles after their
reception into the shuttle box preparatory to their being picked out again; and is
accomplished in the revolving shuttle box loom as follows.
On the box bottom casting at an appropriate distance from the outer end of the
revolving shuttle box is fixed a bracket to which is hinged a metal plate projecting
upwards and suitably formed or shaped to cover all the spaces in the end of the
said revolving shuttle box, except the space at the top which is left open for the
traverse of the picker when picking. To the lower end of this hinged plate, and
at right angles to it, are attached two arms, parallel to each other; one on each
side of the box bottom casting, extending to the outer edge of the draw catches
or hookers, which give motion to the revolving shuttle box. Fixed to each of
these draw catches or hookers, on that part of them immediately above where the
horizontal arms of the hinged plate approach them, is a projecting piece which
overhangs one or the other of the said horizontal arms,
The hinged plate is kept, when not acted on by the draw catches or hookers; in:
its upright position by a spring attached to it, or its horizontal arms, and the box
bottom casting or other suitable part.
Now it will be seen, at each movement made by either of the draw catches or:
hookers for the purpose of turning and changing the shuttle boxes, that by the
projecting pieces fixed on them, coming in contact with the said horizontal arms,
the hinged plate will be drawn clear of any shuttle which may extend from the
outer end of the shuttle box, and also that when the draw catches have gone to
their extent downwards and brought the shuttle box home; their return movement
allows the spring, attached to the hinged plate or its arms, to bring the hinged
plate into its upright position and so press or push any shuttle or shuttles, that
may extend too far out of the outer end of the shuttle box, back into their proper
position and thus prepare them for picking or throwing out again when turned to
the top or level with the shuttle race.

The foregoing description has reference to revolving or circular boxes of the
common or ordinary type, that is, those that revolve or turn only one box at a
time; but our improved arrangement applies, equally, to those which are called
skippers," or which revolve more than one box at once; with the. following
alterations. Instead of the metal plate previously mentioned being hinged, it is
mounted loosely to slide on the revolving box shaft and made to fit a part called
the picker guide, which serves as a stay and guide for it. The two horizontal
arms, as previously described attached to the said sliding plate, are substituted by
one bell cranked lever, which is mounted in a bracket fixed on the box bottom
casting. One end of this 'bell cranked lever is forked or open and spans loosely
the bottom edge of the said sliding plate; the other end extends horizontally until
it comes in contact with the shuttle box operating mechanism in a similar manner
and for the same purpose as previously described, and by the aid of the before
mentioned spring attachment, which is also applied to this plate or its lever, the
required reciprocatory movement is imparted to the sliding plate for the purpose
already set forth. In the foregoing arrangements, for the purpose described, we
have preferably, for economy and simplicity, utilized the motions of the draw
catches or hookers and box operating mechanism, but it will readily be seen that
these can be substituted by other means; such as an independent tappit and lever
arrangement deriving their motions direct from either of the shafts of the loom
and imparting them by suitable connections to the hinged or sliding plate. In this
case the oscillatory or reciprocatory movement of the hinged or sliding plate would
be continuous unless this was obviated by the government of a special card or
indicating motion; and not, as in the previous one, intermittent. Or again we
might, by suitable lever connections, utilize the motion of the slayboard to effect
the desired object; in this case also the movement would be continuous.
The adaptation of our improved arrangements to rising box looms is as follows..
The before mentioned sliding plate is now divided into two parts, which are
suitably shaped for this class of looms, one part extending upwards far enough to
cover all the ends of the shuttles above the picker when the rising box is in its
highest position; the other part extending downwards sufficiently far to cover all
the ends of the shuttles below the picker when the rising box is in its lowest
position. These sliding plates are carried loosely by brackets or stands, upon
which they slide, and which are fixed to the box frame on the front outer side of,
and in suitable proximity with, the rising box, and are pressed into a normal
position by a spring arrangement fixed to them and the box frame or to the
aforesaid brackets. On the rising shuttle boxes are fixed, either small bowls or,
incline pieces which project therefrom sufficiently far to come in contact with
incline pieces rigidly fixed to the sliding plates. These series of incline pieces
being relatively arranged in such a manner that at each movement, either up or
down, of the rising box, an outward movement is imparted to the sliding plates
and when the shuttle boxes become stationary in their proper position with the
shuttle race,
the incline pieces become clear of each other and allow the spring
arrangement to give the reverse movement to the sliding plates; thus effecting a
similar object to that described in connection with the revolving box loom.
A similar variety of mechanisms may be. used for imparting the required
reciprocatory movement to the sliding plates, in this class of looms; to that
described in connection with the revolving box loom, but we only describe the one
which we preferably use.

page_text: We, RICHARD LONGDEN HATTERSLEY, of Keighley, in the County of York,
Machine Maker, EBENEZER HARTLEY and AQUILA ELLIS, both of Tudor Street Shed,
Manchester Road, Bradford, in the same County, Manufacturers, do hereby declare
the nature of our Invention for IMPROVEMENTS IN LOOMS FOR WEAVING 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:-
This Invention relates to revolving or circular and rising box looms and consists
of an improved arrangement of apparatus for adjusting the shuttles after their
reception into the shuttle box preparatory to their being picked out again.
In the accompanying Sheets of Drawings Fig. 1 is an end elevation and Fig. 2
a front elevation of a sufficient portion of a loom to shew the application of our
improvements. Fig. 3 is a sectional elevation of a portion of Fig. 2 through
dotted line A B.
On the box bottom casting C at an appropriate distance from the outer end of
the revolving shuttle box D is fixed a bracket E to which is hinged a metal plate F
projecting upwards and suitably formed or shaped to cover all
Il the spaces in the
end of the said revolving shuttle box except the space at the top which is left open
for the traverse of the picker G when picking. To the lower end of the hinged
plate and at about right angles to it, are attached two arms a parallel to each
other, one on each side of the box bottom casting C, extending to the outer edge
of the draw catches. or hookers H which give motion to the revolving shuttle box.
Fixed to each of these draw catches or hookers on that part of thein immediately
above where the horizontal arms a' of the hinged plate F approach them, is a
projecting piece b' which overhangs one or the other of the said horizontal arms a'.
The hinged plate F is kept, when not acted on by the draw catches or 'hookers, in
its upright position by a spring I attached to its arms a¹ and the suitable part J
above. Now it will be seen at each movement made by either of the draw
catches H, for the purpose of turning the shuttle boxes, that by the projecting
pieces b¹ fixed on them, coming in contact with the said horizontal arms a¹, the
hinged plate F will be drawn clear of any shuttle which may extend from the
outer end of the shuttle box as shewn in dotted lines Fig. 2 F', and also that
when the draw catches H have gone to their extent downwards and brought the
shuttle box D home, their return movement allows the spring I to bring the hinged
plate F into its upright position and so press or push any shuttle or shuttles that
may, as previously said, extend too far out of the outer end of the shuttle box,
back into their proper position and thus prepare them for picking or throwing out
again when turned to the top or level with the shuttle race.
Fig. 4 is a front detail elevation of a modification in the construction of the
hinged plate F and its arm a¹ in connection with the projecting piece b¹ fixed to
the draw catch or hooker H by which means the spring I is dispensed with. As
will be seen the horizontal arm a¹ laying hold of the projecting piece b³ as shewn
in Fig. 4, the oscillatory movement of the hinged plate F will be imparted to it
solely through the medium of the hooker H. When this arrangement is used the
hinged plate F is made in two parts, each part covering one half or part of the
revolving shuttle box respectively the shape of such part being shewn in Fig. 5 F
which is a detail end elevation of same, so that when either of the draw catches.
moves to turn the shuttle box, that part, only, of the hinged plate in connection
with it will be moved, the other (not required to be moved) will be left stationary,

page_text: The foregoing description has reference to revolving or circular boxes of the
common or ordinary type, that is, those that revolve or turn only one box at a
time; but our improved arrangement applies, equally, to those which are called
"skippers" or which revolve more than one box at once, with the following
alterations, which are illustrated by Figs. 6 and 7. Fig. 6 being a front elevation
similar to Fig. 2, and Fig. 7 a sectional elevation of a portion of Fig. 6 through
dotted line A¹ B'. Instead of the metal plate F being hinged, as shewn in
Figs. 1, 2, 3 and 4, it is mounted loosely to slide on the revolving box shaft or its
pedestal J as shewn in Fig. 6, and to fit a part J called the picker guide, which
serves as a stay, and guide for it. The two horizontal arms a¹ as previously
described in connection with Figs. 1, 2, 3 and 4 are substituted by one bell cranked
lever K (Figs. 6 and 7) which is mounted in a bracket L.fixed on the box bottom
casting C. One end of this bell cranked lever K, Fig. 6, is forked or open as shewn
(by the box bottom casting C being cut away) at K₁ and spans loosely the bottom
edge of the said sliding plate F2, the other end extends horizontally until it comes
in contact with the shuttle box operating mechanism in a similar manner and for
the same purpose as previously described. Or if the arm of the lever K is
extended upwards it may be connected loosely to the sliding plate F2 by its forked
end spanning the boss of the said plate F2 in which boss is made a grove as shewn
in detail drawing Fig. 8 K2. In the foregoing arrangements, for the purpose
described we have preferably, for economy and simplicity, utilized the motions of
the draw catches or hookers and box operating mechanism, but it will be readily
seen that these can be substituted by other means, such as an independent tappit
and lever arrangement deriving their motions direct from either of the shafts of
the loom and imparting them by suitable connections to the hinged or sliding
plate. In this case the oscillatory or reciprocatory movement of the hinged plate F
or the sliding plate F2 would be continuous unless this was obviated by the
government of a special card or indicating motion; and not, as in the previous
one, intermittent. Or again we might, by suitable lever connections, utilize the
motion of the slay-board to effect the desired object; in this case also the
movement would be continuous.
The adaptation of our improved arrangements to rising box looms is shewn
in Figs. 9, 10 and 11 of which Fig. 9 is the front, Fig. 10 the end and
Fig. 11 the back elevations of such a portion of a loom as is necessary to
illustrate our Invention. The before mentioned sliding plate is now divided
into two parts which are suitably shaped for this class of looms, one part F³
extending upwards far enough to cover all the ends of the shuttles M above the
picker G when the rising box N is in its highest position, the other part F¹
extending downwards sufficiently far to cover all the ends of the shuttles below
the said picker G' when the rising box is in its lowest position. These sliding
plates F and F are carried, with the parts T1, T2, T3 and T, loosely by brackets
or stands O¹ and O2 upon which they slide, and which are fixed to the box frame P
on the front outer side of and in suitable proximity with the rising box N, and
are pressed into a normal position by springs Q. On the shuttle boxes N are fixed
incline pieces R1 and R2 (or if required these may be substituted by small bowls)
which project therefrom sufficiently far to come in contact with incline pieces Si
and S rigidly fixed by the parts 1, T2, T3 and T to the sliding plates F³ and F.
These series of incline pieces being relatively in such a position that at each
movement, either up or down, of the rising box an outward movement is imparted
to the sliding plates as shewn in dotted lines Fig. 11, and when the shuttle boxes
become stationary in their proper position with the shuttle race, the incline pieces
become clear of each other and allow the springs Q to give the reverse movement
to the sliding plates, thus effecting a similar object to that described in connection
with the revolving box loom. A similar variety of mechanisms may be used for
imparting the required reciprocatory movement to the sliding plates in this class
of looms to that described in connection with the revolving box loom, but we only
describe the one which we preferably use.

page_text: Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed, we declare that what
we claim is :-
1. The use and application of the oscillatory plate F reciprocatory plate F2 and
aliding plates F and F substantially in the manner and for the purpose described
and as illustrated by the accompanying Drawings.
2. The use of the various ways or methods of imparting the motions to the
said plates F, F2, F³ and F in the manner and for the purpose substantially as
fully described and set forth.
