Whiteley & Sons, of Lockwood, near Huddersfield, in the County
of York, Machine Makers, and George Harling, of the same Place,
PROVISIONAL SPECIFICATION left by the said Joe Booth Whiteley
and George Harling at the Office of the Commissioners of Patents,
with their Petition, on the 30th January 1871.
We, JOE BOOTH WHITELEY, of the Firm of William Whiteley and
Sons, of Lockwood, near Huddersfield, in the County of York, Machine
Makers, and GEORGE HARLING, of the same Place, Foreman, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN LOOMS
FOR WEAVING," to be as follows:-
"
This Invention relates to all descriptions of looms in which "rising
boxes or change shuttle boxes are used, for the purpose of weaving
checks, stripes, or other fancy fabrics, but more particularly to that class
employed for weaving woollen or heavy goods of wide width, which looms
require large shuttles and shuttle boxes. In these looms the shuttle
boxes are connected by rods to a lever carrying a shaft on which is

page_text: fixed a bowl or pulley which can be moved to and fro in the lever
transversely by means of jacquard, dobby, or other well known pattern
apparatus so as to place it in position to be acted upon as required by a
single tappet on the crank shaft or a double tappet on the tappet shaft
of the loom for rising the boxes, and hitherto when the change required
by the pattern has to be made, and for that purpose the bowl or pulley
shifted out of position for contact with the tappet, the shuttle boxes
fall by their own gravity, and the momentum not only causes excessive
noise but great wear and tear of the working parts besides great
vibration of the boxes.
Our improvements consist in the employment of an additional bowl
on the bowl shaft or on another shaft in connection therewith, and an
additional tappet or eccentric on the crank or tappet shaft so arranged
that when the first bowl is taken off the first tappet (when required for
the change) the second bowl will be placed in position for contact with
the second tappet, which enables the shuttle boxes to descend easily and
gently without shock.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joe Booth Whiteley and George Harling in the
Great Seal Patent Office on the 28th July 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOE
BOOTH WHITELEY, of the Firm of William Whiteley and Sons, of
Lockwood, near Huddersfield, in the County of York, Machine Makers,
and GEORGE HARLING, of the same Place, Foreman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of January, in the

and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN LOOMS FOR WEAVING," upon the condition (amongst
others) that we, the said Joe Booth Whiteley and George Harling, our
executors or administrators, by an instrument in writing under our,
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 we, the said Joe Booth Whiteley and George
Harling, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement, and accompanying
Sheet of Drawings (that is to say):-

This Invention relates to all descriptions of looms in which “rising
boxes or change shuttle boxes are used for the purpose of weaving
checks, stripes, or other fancy fabrics, but more particularly to that
class employed for weaving woollen or heavy goods of wide width, which
looms require large shuttles and shuttle boxes. In these looms the
shuttle boxes are connected by rods to a lever carrying a shaft on
which is fixed a bowl or pulley which can be moved to and fro in the
lever transversely by means of jacquard, dobby, or other well known
apparatus, so as to place it in position to be acted upon as required
by a single tappet on the crank shaft or a double tappet on the tappet
shaft of the loom for rising the boxes, and hitherto when the change
required by the pattern has to be made, and for that purpose the bowl
or pulley shifted out of position by for contact with the tappet, the shuttle
boxes fall by their own gravity, and the momentum not only causes
excessive noise but great wear and tear of the working parts besides
great vibration of the boxes.
Our improvements consist in the employment of an additional bowl
on the bowl shaft or on another shaft in connection therewith and an
additional tappet or tappets on the crank or tappet shaft so arranged
that when the first bowl is taken off the first or lifting tappet (when
required for the change) the second bowl will be placed in position for
contact with the second or lowering tappet, which enables the shuttle
boxes to descend easily and gently without shock.

page_text: manner.
This Invention will be readily understood by reference to the accom-
panying Sheet of Drawings, wherein Fig. 1 is an end elevation of such
parts of a loom as are necessary to shew our improvements applied
thereto, and Fig. 2 is a portion of the back elevation of same partly in
section taken through the dotted line in Fig. 1. A is the ordinary
lever, which is connected by a rod B to a balanced or weighted lever to
which the shuttle boxes are connected by another rod in the usual
C is the bowl or pulley which is carried on a shaft D supported
in the said lever and capable of being moved laterally or the shaft slided
endways by means of the lever E, which is in connection with and
operated by jacquard, dobby, or other usual or suitable pattern surface
or indicating apparatus. The said bowl is placed in position to be acted
upon by one or other of the tappets F and G (which are fixed on the
crank shaft H) by means of which the boxes are lifted from the bottom
to the next or to the third position as required according as to which
of the tappets the bowl is placed in contact with, and when tho said
bowl is removed out of position for contact with either of the tappets,
and the ordinary holding up catch withdrawn, the boxes are then at
liberty to lower and by their own weight drop to the bottom again,
which sudden action or motion is well known to be the cause of great
noise, vibration of the boxes, and wear of the parts, to prevent which
we apply a bowl I carried on an arm J which is hinged on a shaft K
supported in a bearing fixed on or cast with the lever A, and which bowl
is capable of sliding therein and (being attached to the shaft D by a
plate or strap L in which is a slot hole for a pin on the lever E to work
in) it is moved at the same time as the said shaft D. These Drawings.
On the crank shaft is
show an arrangement for working three boxes.
fixed three tappets M, N, and O, of suitable form and in proper positions
so that when the boxes are required to drop or lower the said bowl I
will be placed in position for contact with either one or other of the
said tappets which by the rotation of the crank shaft will gradually lower
the said boxes from top to the bottom or to the second position or from
the second to the bottom position according as to which of the said
tappets it is placed in contact with. The spring P allows the bowl I
to move out of the way of the tappets M or N when the boxes are in
the second or bottom position, and not required to be lowered or changed
in position. The action of these tappets or apparatus is as follows:
When the boxes are to be in the bottom position, that is, the top box
in line with the shuttle race, the bowl C is moved and placed over the
:-

page_text: circular boss R, but when they are to be lifted to the second position,
that is, the middle box placed in line with the shuttle race, the bowl is
placed as shewn over the tappet F, which will lift them to the position
required, and if the bottom box is to be raised into line with the
race then the bowl is placed over the tappet G, and which being double
the lift of the tappet F will lift them to the top position, it being
understood that the ordinary holding up catches will prevent the boxes
from lowering when the tappets have placed them in position, and after
having passed the bowl and ceased to act thereon. In like manner when
they are to be lowered from the top to the second position the bowl I
is placed over the tappet M as shewn, but when they are to be lowered
from the top to the bottom at once the bowl I is placed over the tappet N
(which is double the amount of incline to the tappet M), and if they are
to be lowered from the second to the bottom the said bowl is placed
over the tappet O. These changes are provided for by a suitable
arrangement of the jacquard cards or other pattern surface that may
be employed for the purpose, as is well understood by all practical
weavers.
Having thus described the nature of our said Invention, and shewn
by Drawings in what manner the same is or may be performed or carried
into practice, we would have it understood that we do not confine
ourselves to the precise manner of applying these additional bowl and
tappets as shewn and described, but we claim the application and use
of such for the purposes herein set forth substantially in manner shewn
and described.
In witness whereof, I, the said George Harling, for and on behalf
of myself and the said Joe Booth Whiteley, have hereunto set
my hand and seal, this Twenty-sixth day of July, in the year
of our Lord One thousand eight hundred and seventy-one.
Witness,
GODFREY BERRY.
GEORGE HARLING. (L.S.)
