Improvements in Shuttle-box and in Shuttle Operating Mechanisms
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, Overlooker do hereby declare
the nature of this invention to be as follows:-
That is to say it relates to improvements in shuttle-box, and in shuttle operating
mechanisms applicable for looms for weaving, and the object of our said invention
is to improve the construction and increase the efficiency of said mechanisms without
increasing the cost of production as compared with mechanisms of the same class
as heretofore constructed..
As regards our improvements in connection with the shuttle-box operating
mechanisms, we make use of the common and well known differential lever arrange-
ment as also the toothed-crank-wheels and the continuously revolving toothed
segment-wheels, said toothed-crank-wheels being operated by the toothed segments
and coupled to the differential levers by suitable connecting rods in a manner
common and well understood.
Heretofore in all the varied arrangements of the above named mechanisms the
toothed-crank-wheels have been mounted upon levers which have been operated by
the pattern mechanism for the purpose of placing said toothed-crank-wheels into and
out of gear with one or the other of the above named toothed segment-wheels, in
this manner necessitating the use of very strong and consequently very cumber-
some pattern mechanisms or pattern surfaces such as metal pulleys or bowls mounted
upon bars carried by metal chains. However according to this invention these
toothed-crank-wheels are mounted upon a stationary pin or shaft and a supplemen-
tary gearing wheel is mounted upon each of the above described levers, each of
said gearing wheels being in constant gear with its corresponding toothed-crank-
wheel, so that, for the purpose of placing any one of the toothed-crank-wheels into
operation, the pattern mechanism is only required to operate the lever carrying the
gearing wheel which enables or allows the use of pattern mechanism or pattern
surface of a neater, lighter and altogether less cumbersome description such as pegs
and neg-lags.

page_text: Again by the above described toothed-crank-wheels being mounted upon a
stationary pin or shaft we are enabled to hinge or joint the connecting rods thereto
in a cheaper and more efficient manner than heretofore. Said jointing consists
of forming (as by casting) the crank pin upon each of the toothed-crank-wheels
for the mounting thereon of the connecting rod, and arranging said wheels so that
one wheel keeps the connecting rod of its neighbouring wheel in proper connection
with its pin as will be well understood.
The jointings of the connecting rods to outer ends of the differential levers are
so formed that by moving said rods from their horizontal position into a some-
what perpendicular position said rods are freed from connection with said pins and
so may be detached for repairing or other purposes.
The box-operating-lever of the differential-levers is joined in the usual well
known manner by rods and chains (which operate around grooved bowls) to the
shuttle box, with the exception that the bowls, chains and rods are so arranged that
the connections from the box operating lever on one side of the loom are carried
along a stationary rail of the loom to the shuttle box on the other side, instead of being
carried along the well known swing rail as has heretofore been the case.
Respecting the shuttle operating mechanism we make use of any of the well known
picking stick mechanisms and means for operating same with the exception that we
employ one set of the hereinbefore described gearing and toothed-crank wheels levers
and connecting rods for the purpose of enabling us to use a portion of the pattern
mechanism employed for controlling the movements of the shuttle boxes, to effect the
placing into and out of operation of the said picking stick operating mechanism.

We RICHARD LONGDEN HATTERSLEY of Keighley in the County of York, Machine
Maker, and JAMES HILL of the same place Overlooker, 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 to improvements in shuttle-box, and in shuttle operating
mechanisms applicable for looms for weaving and the object of our said invention is
to improve the construction and increase the efficiency of said mechanisms without
increasing the cost of production as compared with mechanisms of the same class as
heretofore constructed.
Such being the object and nature of our said invention, in order that same may be
more readily understood, we have hereunto appended sheets of drawings illustra-
tive thereof to which, by figures and letters, reference is made in the following
description.
Figs. 1 and 2 are end and, front elevations, respectively, of a sufficient portion of
a loom to illustrate the application of our invention.
Figs. 3 and 4 are respectively side and top views of portions of the box and shuttle
operating mechanisms formed and arranged in accordance with our invention.
Fig. 5 is a detail drawing hereinafter referred to.
Fig. 6 shews a modified arrangement of our said invention.
Figs. 3, 4, 5 and 6 are of enlarged scale.
Respecting our improvements in connection with the shuttle-box operating
mechanisms, we make use of the common and well known differential lever arrango-
ment a a' as also the toothed-crank-wheels bb and the continuously revolving toothed
segment wheels c c¹, said crank wheels bb being operated by the toothed segments c c¹
and coupled to the differential levers a a' by connecting rods d d in a manner
common and well understood.
Heretofore, in all the varied arrangements of the above named mechanisms the
toothed-crank-wheels bb have been mounted upon levers which have been operated
by the pattern mechanism for the purpose of placing said toothed-crank-wheels bb
into and out of gear with one or the other of the above named toothed segments e c¹,
in this manner necessitating the use of very strong and consequently very cum-
bersome pattern mechanisms or pattern surfaces such as metal pulleys or bowls
mounted upon bars carried by metal chains. However according to this invention
these toothed-crank-wheels are mounted upon a stationary pin or shaft e and sup-
plementary gearing wheels and fl are respectively mounted upon the levers g
and g each of said gearing wheels ff being in constant gear with its corresponding
crank-wheel bb, so that for the purpose of placing any one of the said toothed-
crank-wheels bb into operation, the pattern mechanism is only required to operate

page_text: one or other of the levers go¹ which carry the gearing wheels ff' in this manner
enabling or allowing the use of pattern mechanism or pattern surface of a neater,
lighter and altogether less cumbersome description, such as pegs h and peg-legs h¹
which are brought into position for operating the levers by means of the inter-
mittently rotating cylinder, j; said levers being coupled by the rods k k to the
levers g¹ respectively. In order to retain said levers g gl in proper position during
the movements of the cylinder ;, the lever 7 is made to pass between the outer
ends of the said levers g g' by being operated at the desired time by the spring m¹
as is regulated by a suitably shaped cam which is mounted upon the shaft m,
said movements being imparted from one to the other by means of the connecting
rod n.
By the above described crank-wheels bb being mounted upon a stationary pin
or shaft as the shaft e, we are enabled to hinge or join the connecting rod d d¹
thereto in a cheaper and yet more efficient manner than heretofore. Said jointing
consists of forming (as by casting) a crank-pin 62 upon each of the wheels bb,
for the mounting thereon of the connecting rod d or d', and arranging said wheels bb
so that one wheel keeps the connecting rod d or d' of its neighbouring wheel in
proper connection with its pin as will be well understood, a plate or annular
piece of metal o being employed to keep the outermost connecting rod in said
position.
The jointings of the connecting rods d d¹ to the outer ends of the levers a a¹
respectively, are so formed (as shown by detail drawing fig. 5) that by moving
said rods d d from their operating position, which is horizontal and relatively at
right angles to the somewhat perpendicular position shewn by fig. 5 or somewhat
into a straight line with the said levers a a¹, said rods d d' are freed from connection
with the pins a² and so may be detached for repairing or other purposes.
The levers a a¹ are joined in the usual well known manner by chains
P (which
operate around grooved bowls p¹) and rods p² to the shuttle boxes p³ with the
exception that the bowls p' are so arranged that the connections, from the levers a a¹
to the shuttle boxes on the opposite side of the loom, may be carried along the
stationary rails instead of being carried along the well known swing rail or
slay board as has heretofore been the case. By a slight modification in the arrange-
ment of the connecting rods d d', wheels b, c, c¹ and f f and levers g g¹ the
same may be employed with equal advantage for operating the healds used in looms
for weaving, by simply dispensing with the levers a a¹ and making use of the
bell-cranked levers a shewn by fig. 6 the same being coupled in the well known
manner to the healds a' by means of the cords as and levers a³.
Respecting the shuttle-operating mechanism, we make use of any of the well
kown picking stick mechanisms k and means for operating same, with the exception
that we employ one set of gearing wheels b, f, connecting rods, d and k levers g
and i and a levert for the purpose of enabling us to use a portion of the pattern
mechanism shewn by figs. 1 and 2, which is employed for controlling the movements
of the shuttle boxes as hereinafter described, to effect the upward and downward
movements of the rod u, which is joined in the well known manner to the lever v,
for placing the other well known parts into and out of operation for effecting the
movements of the shuttle as may be desired, so that when the direction of motion
of the cylinder j is reversed, by the operative moving the handle lever w, which
is coupled, by the rod w¹ reaching to the lever rigidly mounted upon the loosely
held shaft to the lever y (also rigidly mounted on said shaft ¹) which
places one or the other of the pins on the nogging wheel z, into or out of
position for operating the crown wheel which is mounted upon the shaft of the
cylinder j, a reversion in the direction of motion of the shuttle box and the
disengagement of the picking stick operating mechanisms are simultaneously effected
(said disengagement being accomplished by the rod ws joining the handle lever w to
the lever which operates the lever vin a manner well known) so that the
movements of the one do not become disconcerted with the movements of the other.

tion, and in what manner the same is to be performed, we declare that what we
