Year: 1876

page_text: LETTERS PATENT to James Hollingworth, of Dobcross, Saddleworth, in the
County of York, Machinist, and Joseph Hollingworth, of the said Dobcross,
Mechanic, for the Invention of "IMPROVEMENTS IN LOOMS FOR WEAVING."
Sealed the 30th May 1876, and dated the 17th March 1876.
PROVISIONAL SPECIFICATION left by the said James Hollingworth and
Joseph Hollingworth at the Office of the Commissioners of Patents on the
17th March 1876.

Machinist, and JOSEPH HOLLINGWORTH, of the said Dobcross, Mechanic. "IM-
PROVEMENTS IN LOOMS FOR WEAVING."
Our Invention relates to means by which to facilitate changes in the use of what
are called rising boxes, and the improvements apply particularly to that class of
means for operating such shuttle boxes, described in the Specification of Letters
Patent granted to me the said James Hollingworth, and John Hirst, Junior, bearing
date the 2nd of February 1859, No. 304.
The object of the present improvements is to obtain ease and reduce vibration in
effecting changes from the upper to the lower of a series of boxes, and also to assist
the rising motion. For this purpose, in addition to the series of tappets acting by
leverage and connecting rods to raise the boxes as well as to release and regulate
the position of the holding or catch lever, we employ an additional series of tappets
also capable of sliding with the former series longitudinally of the shaft to which
they are applied, so that any one of the rises of this extra series of tappets may be
brought into position to act in its rotation on the bowl of a lever to actuate a
sliding bar, and thereby bring an incline on such sliding bar over an extra roller or
bowl carried by the leverage acted upon by the first series of tappets. This sliding
bar is borne upon by a spring just sufficiently strong to retain the incline of that
sliding bar in position bearing on that extra roller as selected. The holding or
catch lever, as heretofore, holds the boxes in position whilst the respective series of
tappets are shifted endwise on their shaft for the next change, and then, when in
the rotation of both series the holding or catch lever is by the action of a tappet
becoming free of the stop or catch it held, then the sliding bar with its incline may
be gradually shifted by the action of one of the additional tappets, to let the boxes
down gradually to the extent desired to bring a fresh stop to rest on the holding or
stop lever. The action of the spring on the sliding bar by the incline pressing on
[Price 8d.]

page_text: the extra roller also aids the rising motion of the series of boxes. By these means
facility is afforded for the use of additional box chambers in each series. Both
series of tappets are shifted endwise on their shaft as desired for change of position
or for rest by leverage and connecting rods, acted on by jacquard or other suitable
selecting means as heretofore.

PROVEMENTS IN LOOMS FOR WEAVING."
Our Invention relates to means by which to facilitate changes in the use of what
are called rising boxes, and the improvements apply particularly to that class of
means for operating such shuttle boxes, described in the Specification of Letters
Patent granted to me the said James Hollingworth, and John Hirst, Junior, bearing
date the Second of February 1859, No. 304.
The object of the present improvements is to obtain ease and reduce vibration in
effecting changes from the upper to the lower of a series of boxes, and also to assist
the rising motion. For this purpose, in addition to the series of tappets acting by
leverage and connecting rods to raise the boxes as well as to release and regulate
the position of the holding or catch lever, we employ an additional series of tappets,
also capable of sliding with the former series longitudinally of the shaft to which
they are applied, so that any one of the rises of this extra series of tappets may be
brought into position to act in its rotation on the bowl or part of a lever to actuate
a sliding bar, and thereby bring an incline on such sliding bar over an extra roller
or bowl carried by the leverage acted upon by the first series of tappets. This
sliding bar is borne upon by a spring just sufficiently strong to retain the incline of
that sliding bar in position bearing on that extra roller as selected. The holding or
catch lever as heretofore holds the boxes in position whilst the respective series of
tappets are shifted endwise on their shaft for the next change, and then, when in
the rotation of both series the bolding or catch lever is by the action of a tappet
becoming free of the stop or catch it held, then the sliding bar with its incline may
be gradually shifted by the action of one of the additional tappets to let the boxes
down gradually to the extent desired to bring a fresh stop to rest on the holding or
stop lever. The action of the spring on the sliding bar by the incline pressing on
the extra roller also aids the rising motion of the series of boxes. By these means
facility is afforded for the use of additional box chambers in each series. Both
series of tappets are shifted endwise on their shaft as desired for change of position
or for rest by leverage and connecting rods, acted upon by jacquard or other suitable
selecting means as heretofore.
But that the Invention may be more fully understood, we will, by the aid of the
accompanying Drawings, proceed to describe means pursued by us in carrying the
same into effect.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shews the outline of so much of the end framing of a loom with some
of the working parts thereof, such as described in the Specification of the said
former Patent above referred to, and adaptations thereto according to our present
T

page_text: Figures 9 and 10 shew by edge view and side view the bar n and parts thereof
separately. Figures 11 and 12 shew an edge view and a side view of the lever h
and parts thereof separately.
In all the Figures the same letters are used to indicate the same parts wherever
they occur. a, a, shews the main end framing; the crank axis, to which motion
is given from a steam engine or other suitable power by means of a strap or band
acting on a pulley applied on that shaft b, as is well understood. a¹ is a bracket
affixed to and standing out from the main framing to aid in supporting the outer
end of this axle b. c is the batten, and c¹ one of the swords or supporting arms to
the batten, by which the batten and parts carried thereby are suspended to swing
from the upper part of the main framing a in the usual manner.
As shewn, there are four shuttle chambers, 1, 2, 3, 4, in the sliding shuttle box d,
and this box is suspended to slide vertically or up and down on bars e, carried by
the end frame of the batten c, and the series of shuttle chambers are suspended
from one end of the lever f by means of rods d¹, one end of each of which is by pin-
joint de connected to the box d, whilst the other end of each of these rods d¹ is by
pin-joint d³ connected with facility for adjustment to the one end of the lever f.
This lever f is supported to rock on a stud ƒ¹, carried by the main framing, whilst
the opposite end thereof carries an adjustable stud f to receive one end of the
connecting rod g, the other end, g¹, of which is connected with capability of adjust-
ment to one end of a lever h. This lever at its opposite end is supported to turn
on the fixed stud h¹, carried by the main framing, and it is operated as hereafter
described for effecting the raising and the lowering of the series of shuttle chambers,
as will presently be more fully seen. k is the catch lever, which is supported to
turn on the stationary stud / projecting from the side framing of the loom, and it
is formed at its upper end to receive one or other of the adjustable studs 5, 6, 7, or 8,
applied with capability of adjustment in the lever f, so that the shuttle chambers
may be correctly held as selected. A, B, and C are the series of cams or tappets
for raising the boxes as well as for releasing the catch lever k from the holding
studs 5, 6, 7, or 8, and also for regulating the position of that holding or catch
lever k. This series of cams or tappets A, B, C, as heretofore is capable of being
slided endwise on the shaft or axis 6, but according to our present improvements
there is applied on the boss or tube carrying these tappets A, B, C, additional
tappets D and E, and all these tappets are capable together of being slided by
means of the lever m, the forked lower end of which embraces the collar ¹ formed
on or affixed to the boss or tube l. The lever m is supported to rock on the fixed
stud m², and at its upper end is, by pin-joint m², connected to a rod operated to
give to it, and thence to the series of tappets A, B, C, D, E, the movement on the
shaft b for the time desired. To ensure these tappets revolving with the shaft b
whilst they are capable of being moved endwise thereon, the tube is formed in
the direction of its length with a groove to receive a pin or feather, affixed to project
from the surface of the tube 6¹ in the usual way in such cases. The tube b¹ is
affixed so as to form an enlarged part of the shaft b. By these means any of the
tappets may be brought into the relations desired.
n is a bar which is supported so as to be capable of sliding freely in openings
formed for it in the bracket a¹, and it is borne upon with a tendency to draw it
in one direction by means of a spring n¹, one end of which is looped on to the
stud n carried by the bar n, whilst the other end is connected to an adjustable
screw stem n³. On this bar n is affixed with capability of adjustment the plate n³,
the lower edge or surface of which is inclined, and is applied to rest on the extra
bowl no, supported to revolve on a stud no projecting from the lower part of the
lever h. One object of the spring n' is to hold the inclined lower surface of the
plate n in the position selected for it to bear on the bowl n; the tension or
pressure exerted by the spring n¹ employed should therefore be sufficient to hold
the incline n', resting with the portion of it in the position selected, bearing against
the surface of the bowl n³.
Whilst the tendency of the spring n¹ is to draw the bar n in one direction

page_text: .
against the force exerted by the pressure of the bowl n³ on the incline n', the
bar n is when required moved in the opposite direction by one or other of the
tappets D or E acting on the upper end of the lever o, the lower end of which is
formed with a slotted opening to receive the small roller n applied to turn on a
stud carried by the rod n.
To simplify the number and action of the respective tappets A, B, C, D, and E,
the surfaces on which they act are all formed double, thus the bowl p carried by
the lever his formed in two diameters 9 and 10, whilst the upper end of the
lever o is formed with two acting surfaces 11 and 12, and the lower end of the
lever k is also formed with two acting surfaces 13 and 14, and as shewn, these
respective surfaces are formed to act with the respective tappets A, B, C, D, and E
in the following relations, but we do not confine ourselves thereto. ol is the
stationary axis of the lever o.
As the parts are shewn, the series of shuttle chambers have been lowered so as
to remove the chamber 1 from a line with the race, and bring the chamber 2 in
that line; to effect the movements required for this change the tappet E has acted
on the surface 12 of the lever o, the tappet C has acted on the surface 13 of the
holding lever k, and the tappets A and B have acted on both surfaces and 10
of the bowl p carried by the lever h.
In order to move the series of boxes so as to shift the chamber 2 from being
in a line with the shed, and bring the chamber 3 into that line, the series of tappets
will together be slided on the crank shaft b, so as to cause the tappet Ę to act on
the surface 11, at the upper end of the lever o, the tappet C acts on the projection
14 at the end of the lever k, and the tappet A acts on the surface 10 of the bowl p.
In order to shift the series of boxes so as to remove the chamber 3 from a line with
the race and bring the chamber 4 into that line, the series of tappets A, B, C, D, and
E will be shifted on the shaft or axis b, so as to cause the tappet D to act on the
surface 11 at the upper end of the lever o, the tappet B will act on the surface 14
of the lever k, the bowl p of the lever will not be interfered with.
In order to make a change so as to shift the chamber 1 from a line with the race,
and bring the chamber 4 into that line, the series of tappets A, B, C, D, and E will
be shifted slightly on the shaft or axis b, so that the tappet D will again act on
the projecting surface 11 of the lever o, and the tappet B will again act on the
surface 14 of the lever k, and the surfaces 9 and 10 of the bowl p, will be omitted
to be acted upon.
In order to shift the series of boxes so as to remove the chamber 2 and bring
the chamber 4 in a line with the shed, the series of tappets A, B, C, D, and E will
be slided on the shaft b, so as to cause the tappet D to act on the surface 11 of the
lever o, and cause the tappet B to act on the surface 14 of the lever k.
It will thus be seen that when by the action of the tappets B or C on the lower
end of the lever k to release the upper end of that holding or catch lever from
acting to hold up the boxes by acting on any one of the stops 1, 2, 3, or 4, the
tappets E and D will act on the upper end of the lever o gradually to move that
lever, and consequently the bar n and the incline surface to the plate n* so as to
admit of the bowl no gradually rising up that incline and by the lever h, connecting
rod 9, and lever f effecting an easy descent of those boxes so as to avoid jerking and
noise in effecting those changes.
It will also be seen that when the tappets A, B, or C act on the bowl p of the
lever and through the connecting rod g to the lever f, to effect the rising of the
series of boxes, the action of the incline surface to the plate n' will by the force
of the spring n³ aid such rising motion of the series of boxes.
Although the parts as shewn are arranged for working with four shuttle chambers
in the series, it will readily be understood that such number may be varied and
from the description given the acting parts varied accordingly.
Having thus described our Invention, and means we adopt in carrying the same
into effect, we would have it understood that we do not confine ourselves to the
precise arrangements of parts as shewn and described, as the same may be varied

page_text: without departing from the peculiar character of the Invention, but what we do
claim is
The arranging or combining parts whereby an incline or such like operating
piece, acted upon by spring pressure and extra tappets applied, to be slided as
required with the lifting and catch lever tappets is used to act with a bowl or other
suitable surface to case the descent of the series of boxes, and also to aid their
ascent as described.
In witness whereof, we, the said James Hollingworth and Joseph Hollingworth,
have hereunto set our hands and seals, this Eleventh day of September, in
the year of our Lord One thousand eight hundred and seventy-six.
