page_text: LETTERS PATENT to Jonas Craven, of Bradford, in the County of York,
Designer, Wignall Hey, of Manningham, near Bradford, aforesaid,
Mechanic, and Charles Worsnop, also of the aforesaid Manningham,
Overlooker, for the Invention of "IMPROVEMENTS IN ACTUATING ROTARY
SHUTTLE BOXES OF LOOMS."
Sealed the 13th April 1858, and dated the 23rd January 1858.
PROVISIONAL SPECIFICATION left by the said Jonas Craven, Wignall
Hey, and Charles Worsnop at the Office of the Commissioners of Patents,
with their Petition, on the 23rd January 1858.
We, JONAS CRAVEN, of Bradford, in the County of York, Designer, WIG-
NALL HEY, of Manningham, near Bradford, aforesaid, Mechanic, and CHARLES
WORSNOP, also of the aforesaid Manningham, Overlooker, do hereby declare
the, nature of the said Invention for "IMPROVEMENTS IN ACTUATING ROTARY
SHUTTLE BOXES OF LOOMS," to be as follows:-
The improvements have for their object simplicity with facility of working
in giving motion to rotary shuttle boxes. Upon the tappet or other suitable
shaft of the loom is affixed a tappet capable of sliding on such shaft, though
it is controlled to rotate with it. The sliding of the tappet is effected at the
times desired by the action of jacquard or other suitable pattern surface, and

page_text: is for the purpose of placing that tappet in position for acting upon one or the
other of a pair of levers, or so that it may rotate free of either of them. These
levers capable of being so operated upon, turn each upon a centre of motion,
and are connected to catches or drivers for operating upon studs or teeth in
a wheel or plate to give rotary motion thereto, one in one direction, the other
in the opposite. The wheel or plate so operated is provided with studs and
segmental pieces to act upon a star wheel affixed upon one end of the box or
series of shuttle chambers. Steadying means are applied to hold the wheel or
plate operating the star wheel, to prevent motion except when operated by
the catches or drivers.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jonas Craven, Wignall Hey, and Charles Worsnop in the
Great Seal Patent Office on the 23rd July 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we,. JONAS
CRAVEN, of Bradford, in the County of York, Designer, WIGNALL HEY, of
Manningham, near Bradford, aforesaid, Mechanic, and CHARLES WORSNOP,
also of the aforesaid Manningham, Overlooker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters.
Patent, bearing date the Twenty-third day of January, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Jonas Craven, Wignall Hey, and Charles Worsnop, Her special
licence that we, the said Jonas Craven, Wignall Hey, and Charles Worsnop,
'our executors, administrators, and assigns, or such others as we, the said
Jonas Craven, Wignall Hey, and Charles Worsnop, our executors, adminis-
trators, and assigns, should at any time agree with, and no others, from
time to time and at all times thereafter during the term therein ex-
pressed, 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 "IMPROVEMENTS IN ACTUATING ROTARY
SHUTTLE BOXES OF Looms," upon the condition (amongst others) that we,
the said Jonas Craven, Wignall Hey, and Charles Worsnop, our executors
or administrators, by an instrument in writing under our or their hands and
seals, or under the hand and-seal of one of us or them, should particularly
describe and ascertain the nature of the said Invention, and in what manner

page_text: 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 Jonas Craven, Wignall Hey, and
Charles Worsnop, 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 statement thereof, that is to:
say:
+
The improvements have for their object simplicity with facility of working,
in giving motion to rotary shuttle boxes. Upon the tappet or other suitable
shaft of the loom is affixed a tappet capable of sliding on such shaft, though
it is controlled to rotate with it. The sliding of the tappet is effected at the
times desired by the action of jacquard or other suitable pattern surface, and
is for the purpose of placing that tappet in position for acting upon one or the
other of a pair of levers, or so that it may rotate free of either of them. These
levers, capable of being so operated upon, turn each upon a centre of motion,
and are connected to catches or drivers for operating upon studs or teeth in
a wheel or plate to give rotary motion thereto, one in one direction, the
other in the opposite. The wheel or plate so operated is provided with studs
and segmental pieces to act upon a star wheel affixed upon one end of the
box or series of shuttle chambers. Steadying means are applied to hold the-
wheel or plate operating the star wheel to prevent motion, except when
operated by the catches or drivers:
But that the nature of these our improvements, and the best means we are
acquainted with for carrying the same into effect, may be fully understood, we
will proceed to describe the Drawings annexed.

DESCRIPTION OF THE DRAWINGS.
Figure 1 shews a front view, and Figure 2 an end view of a loom with the
improvements applied thereto. a is the main or crank shaft giving motion, as
is well understood, by suitable toothed gear to the cam or tappet shaft b, upon
which is applied the tappet or cam c, which is formed with a groove in its
socket to receive a rib or feather affixed on it, or otherwise it is connected to
the shaft 6 in such manner that whilst the cam or tappet c is controlled to
rotate with the axis b, it is yet capable of sliding thereon, and the sliding.
given to the tappet along the shaft 6 is such that in its revolution it may
operate upon either of the trucks or bowls d or e, carried by their respective
levers d' and e', or it may in its revolution miss both of them. This motion

page_text: act in its revolution
or fis lifted, the
cam or tappet c to
to the cam or tappet c is according to the arrangement shown effected by the
boss cof the cam or tappet c, having a groove or neck formed around it,
which is embraced by a fork f affixed to one end of the L lever f', which
turns upon the fixed axis f³, and towards the other end is attached to the
cords f, f, in connection with and to be operated in the ordinary manner by
the jacquard apparatus or other suitable pattern surface, and the parts are so
arranged that when the cord f³ is lifted, the tappet c will be moved into
position to act in its revolution upon the truck or bowl e. When the cord f
is lifted the tappet or cam c will be placed in position to
on the bowl or truck d, but when neither of the cords f
weight at the outer end of the lever will cause the
be drawn to the extreme left so ás to miss both 'trucks or bowls d and e.
When the lever 'f' has been acted upon to be lifted by the cord f³, its
weighted end will be caught by the notch (1) in the sliding plate i, and when
lifted by the cord the weighted end of the lever f¹ will be caught, and for
a time held by the notch (2) in the sliding plate i. The plate i has two arms
(3) and (4), by which it is supported, with a capability of sliding in the sta-
tionary frame or support. k, and the arm (4) has a stud projecting from it
which is acted upon by a spring (5), with a tendency to force the plate i
towards the lever f¹. When the lever f¹ has been held for the time required
by either of the notches (1) or (2), it is relieved therefrom by the jacquard or
other pattern surface employed, acting upon to pull the cord 1, the lower end
of which is made fast to the pulley upon the axis 2, upon which is also
affixed the pulley 3, to which is affixed one end of a cord m, the other end
of which is affixed to the plate i, by which the platė i will be drawn back to
release the lever f¹. The levers d¹ and e¹ turn upon a centre of motion g.
The lever d by the rod d2, acting upon studs in the wheel h, gives motion to
that wheel in one direction, whilst the lever e¹, by the rod e acting upon
those studs in the wheel h, gives motion to it in the opposite direction. The
wheel his formed with studs and segments to act upon the star wheel j,
affixed to the end of series of shuttle boxes, as is well understood, in giving
motion to such shuttle boxes; 'n is a spring which by acting on one of the
faces of the triangle o, serves to steady the parts between the motions..

Having thus described the nature of our said Invention, we would have
it understood that we do not confine ourselves to the precise details shewn and
described, as these may be varied; but what we do claim is the arranging,
combining, and operating parts substantially as explained, whereby a suitable
cam or tappet is capable of sliding upon its axis in order that it may be moved

page_text: nto and held in position to act upon either of the levers for operating the
series of shuttle chambers, or of missing them by jacquard or other pattern
surface employed.
In witness whereof, we, the said Jonas Craven, Wignall Hey, and Charles
Worsnop, have hereunto set hands and seals, this Twentieth day of
July, in the year of our Lord One thousand eight hundred and fifty-
eight.
