PROVISIONAL SPECIFICATION.
Improved Mechanism for Controlling the Movements of Loom
Shuttle-boxes.
I, AMOS LOCKWOOD of 38 Willow Bank King Cross, Halifax in the County
of York, Machine Maker, do hereby declare the nature of this invention to be as
follows:-
In looms having moveable shuttle-boxes (either of the class known as rotary or
those called "rising and falling" shuttle-boxes) which are arranged to be operated
so as to bring each of the several shuttles into operation in accordance with the
design to be produced, it is often found that a long series of changes has to be
passed through before such design repeats itself or is repeated, consequently it is
necessary to employ a pattern surface of considerable magnitude to effect such
production, and to condense this pattern surface by the employment of an
arrangement and combination of parts or means is the object of this invention.
To attain this object I make use of cards or peg-lags (preferably the latter.
hence I refer to these alone in the following description although it is well known
that the former are often and extensively used in place of these latter) having six
or more rows of indicating holes, half the number of said rows of holes being in
operating position at one.time the other half at another time. In connection with
each of the rows of holes that are in operating position I arrange to operate a
lever, one of these levers having control over the movements of the pattern-
cylinder while the other levers whether they are two or more in number (two
being used in the case of a common revolving or rotary box loom, and more
provided the loom is what is known as a skip (rotary) box loom wherein anyone of
the series may be brought into position for use or provided the loom is what is
known as a rising box loom, with boxes for four or more shuttles, then, in like
manner, the number of these levers will be increased accordingly as will readily be
understood, each movement being effected by or through its corresponding lever)
are for controlling the movements of the shuttle-boxes by putting the box
operating mechanism into and out of motion as and for the purposes desired, be the
said box operating mechanism any one of the several well known kinds or
description.
These levers, which operate in connection with the pattern surface, are mounted
on hinged supports or supplementary pivotted levers which are caused to move
backwards and forwards, or to oscillate, by a rotary cam operated in turn by
suitable ratchet and wheel mechanism in such a manner that as the cam is being
intermittently rotated, their outer ends are successively presented or brought into
position for being operated upon by each hole in its respective row of boles,
commencing at one end of the peg-lag travelling over it to the other end and as
regularly travelling back again along its other respective row of holes, the pattern
cylinder having been moved forward or caused to move vertically in another path
of motion in order that this second series of holes in the lag may be brought into
the proper vertical plane in which the levers above described are situated.
Suitable cam, lever, or other mechanism and guiding devices being employed for
causing the pattern cylinder to operate in this manner.
The lever for controlling the movements of the pattern cylinder is arranged so
that by the pattern surface acting upon it to put it into operation; the cam

page_text: movement, bỷ suitable additional ratchet and wheel mechanism, causes it as well as
its accompanying levers to return or advance to their normal or back position, that
is to say, provided the end of the design being produced falls at any part on the
pattern surface along the series of holes in the lag that are visited on the
advansing movement of the lovers, then such pattern surface will be prepared to
operate the indicating lever so that the series of levers will return to the end from
which they commence their movement, on which the pattern cylinder will be
rotated or moved to bring the next lag into position; however provided the end of
the design falls upon the other rows of holes over which the levers are moving
during their receding movement, then the indicating lever will put the parts into
operation so that the levers continuing their receding movement at one bound
arrive at the same position as above described and with the same results.
The rotary motion of the pattern cylinder is as above described directly under
the control of the indicating lever in the series upon which it acts, and such control
is arranged by suitable lever and other devices so that it can only cause the said
cylinder to be rotated at each time that the said levers are in their normal back
position while by other incline and lever mechanism the advancing or guiding of
said cylinder to present the second rows of holes on the lag in action to the
operating levers is arranged to take effect only when the said levers are in their
most forward position.
The pattern cylinder has its rotary motion imparted to it by any well known
ratchet and wheel mechanisms the same arranged by being coupled to the parts
above described to be controlled by its pattern surface, while the vertically
reciprocatory motion thereof is effected by means and in the manner already well
known.

Improved Mechanism for Controlling the Movements of Loom
Shuttle-boxes.
I, AMOS LOCKWOOD of 38 Willow Bank, King Cross, Halifax in the County
of York, Machine Maker, 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 :-
In looms having moveable shuttle-boxes (either of the class known as rotary or
those called "rising and falling" shuttle-boxes) which are arranged to be operated
so as to bring each of the several shuttles into operation, in accordance with the
design to be produced, it is often found that a long series of changes has to be
passed through before such design repeats itself or is repeated, consequently it is
necessary to employ a pattern surface of considerable magnitude to effect such
production, and to condense this pattern surface by the employment of an
arrangement and combination of parts or means is the object of this invention.

views.

To attain the object of my invention I make use of cards or peg-lags (preferably
the latter, hence they alone are shown in the annexed drawings and referred to in
the following description although it is well known that the former are often and
extensively used in place of the latter) having six (or more than six as will
hereinafter be described) rows of indicating holes a b c and a¹¹ c', half the number
of said rows of holes being in operating position at one time, the other half at
another time, as shown by Figs. 9 and 10, the rows abe being shown in operating
position by the former figure while those at a² b' c' are shown in operating position
by the latter.
In connection with each of the rows of holes that are in operating position
I arrange to operate a lever, as the levers def, one of these levers (the lever e)
having control over the movements of the pattern cylinder y while the other
levers d and fare for controlling the movements of the shuttle-boxes, by putting
the box operating mechanism into and out of motion as and for the purposes
desired, be the said box operating mechanism any one of the several well known
kinds or descriptions.
ог
The well known kind of rotary shuttle-box operating mechanism herein shown
consisting of the cam 2 fixed on the loom's rotary shaft 3 so that it may impart
reciprocatory motion to the lever 4 in order that when either of the catches
is made to engage with this lever 4 its respective box lever 7 or 8 will cause its
hooker 9 or 10 to rotate the shuttle box through the medium of the peg-
wheel 11. And the engagement of these catches 5 and 6 with the lever 4 is
effected by the levers 12 and 13 which are caused to oscillate by the rod 14
operated by the eccentric 15, the outer ends of these lovers being heretofore
allowed to descend directly into contact with the pattern surface of a pattern
cylinder which arrested them in such descent so as to prevent their other ends y
from causing their catches 5 and 6 to engage with the lever 4 or it allowed them to
descend so that these catches would be placed into contact with the lever 4 as
the case might be. However in connection with my, invention these levers 12
and 13 have the pendent detaining catches 16 and 17 pivotally attached to
them so that they may be controlled by the cylinder g as hereinafter described.
Or the levers 12 and 13 and the catches 16 and 17 may be dispensed with
as shown by Fig. 11, wherein the catches and 6 are directly operated by the
cylinder g.
In Fig. 12-the drop box mechanism consisting of the differential levers 18
and 19 operated by the gear cranks: 20, 21 through the rods 22, 23, is the one
shown as being suitable for controlment by my improved mechanism, the
cylinder in which selects or operates the gear cranks 20, 21 by the levers 24, 25

page_text: rods 26, 27 so that their retaining lever 28 may move and keep them in gear
with one or other of the toothed segments 29 or 30 in the manner and for the
purpose well known.
The actions of my pattern mechanism for putting the shuttle-box into motion
are as follows ;-
When the cylinder has its pattern surface prepared to act upon the levers df
as by pegs being placed in the holes a c or a¹ c', on such cylinder 9 being raised
against the levers d and f said pegs will come in contact with the outer ends of the
levers df (into which are fixed the pins h) raising said ends of these levers & fand
depressing the other ends at k so that the rods m m¹ are forced downwards over-
coming the actions of gravity on the levers n n' (or n² n³) and forcing by their
rods oo the catches 16 and 17 off their retaining piece 31 and allowing the
levers 12 and 13 (which at such time would not be held suspended by the rod 14
and its eccentric 15) to move the catches 5 and 6 as desired. Or the rods o o'
would act upon the catches 5 and 6 as shown by Fig. 11. The levers. n* nº and
rods m² m² operate the gear cranks 20, 21, to cause the rising box to be moved as
do the rods o o' the catches 5 and 6 for causing the circular box to rotate.
It will be seen from the foregoing that more than two of these levers d and f
might be employed provided a corresponding increase in the number of rows of
indicating holes ac are made in the lags, although only two of such levers and
their respective connecting rods and parts are shown and described, since only. a
common revolving and not a skip rotary box is shown, nor is a more extensive
drop-box than one with a series of four compartments referred to because by
describing my invention in connection with these simpler forms it will be more
readily understood while its carrying out in a more extensive manner only requires
an increase in the number of its several parts.
The levers def are mounted upon the sliding piece p (or instead of this piece p,
pivoted levers arranged to assume vertical positions might be employed) which is
caused to move or advance upon the bearing 9 in the direction indicated by
the arrow (Fig. 2, 9 and 10) by the cam s while its return movement is effected
by the spring through the lever and chain although such return may be
controlled by the cam s as is hereinafter described.
This cams is intermittently rotated by the ratchet t through the wheel t' which
is fixed upon the cam shaft s, its position at each movement being secured by the
spring u forcing the bowl u' carried by the lever u² against the star wheel u³, while
the ratchett receives its reciprocatory motion by being mounted upon the lever v
pivotted at and operated by the rod which couples it to the vertical support o
upon which the cylinder g is mounted. The vertical movement of the support a
(and consequently the cylinder g) is effected by the eccentric 15 through the
rod 14 and the chain v, as shown by Fig. 1, or through the lever to as shown by
Fig. 11, while the return movement of this cylinder 9 is effected by gravity aided
by the spring to which by its actions on the lever v causes the rod to press the
support in a downward direction and the attachment of this rod to the
support by the projecting arm in addition to its downward pressure also tends
to force its upper end on which the cylinder g is mounted in the direction
indicated by the arrow 2, by which means the piece w³, which slides horizontally
upon the bearing shaft and in which the upper end of the support slides
vertically (see Figs. 9 and 10) is always pressed forward so that its antifriction
bowl w is thus constantly kept in contact with the cam surface u on the star
wheel u³.
As the cams is thus intermittently rotated the outer ends of the lever def
carrying the pins are made to advance over the pattern cylinder g in successive
steps, which are made to agree with the distances that the holes are from each
other lengthwise their rows, the turn of rest of such cams and levers d e f being
arranged to take place at the time of the ascent of the cylinder g (the extending
ends of said levers d f being sufficiently long so that they will not be drawn
clear of the rods m m³ in or by their said advancing movements), so that their

page_text: said onter ends are successively presented or brought into position for being
operated upon by each hole in their respective rows of holes, commencing at the
end g of the peg-lag travelling over it on the rows a b c to the other end and as
regularly travelling back again along the other rows a¹ b' c', the cylinder 9 having
advanced in the direction of the arrow z since the cam surface will have allowed
it to do so at this time, notwithstanding, and in addition to, its continned rising
and falling movements.
g
The lever e which is referred to herein as governing or coutrolling the move-
ments of the cylinder g does so in a certain measure as far as regards its rotary
motion, and this is effected as follows;-Provided the end of the design being
produced falls at any part on the pattern surface along the series of holes a b c
then such pattern surface will be prepared as by a peg being placed in the lag so
that on the rising of the cylinder the lever e is raised, then the end e¹ of the
lever e will be raised while the end e is lowered thus the catch e* which it supports
falls into contact with the projecting pin on the ratchet t in order that on the
next movement of the lever vit may be lifted out of contact with its wheel t¹ while
at the same time it overcomes the spring u pulling the lever u³ and its bowl u¹
clear of the wheel u thus the pressure of the retracting spring r, now that the
cam s is not held, forces the slide p back to its normal position (as shown by Fig. 9)
bringing with it the levers def that it carries. On the levers d e f returning to
the position last described the lever 33 which is also pivoted on the slide p, returns
to its rear position in which its inclined edge 34 is pulled over the portion of the
bearing g, which supports it thus it is raised bringing with it the weighted arm 35
of the ratchet 36 (which weighted arm by gravity always tends to keep the
ratchet 36 clear of the peg wheel on the cylinder g) so that this latter is brought
into contact with the ratchet wheel on said cylinder by which means on the
cylinder again descending it is caused to rotate to bring its next peg-lag into
position.
Again provided the end of the design or pattern being woven falls upon the rows
of holes a b c then the indicating lever e will again be operated so that the slide p
and its levers def will be caused to continue their receding movement but at this
time will finish same at one bound and will arrive in their said normal positions in
which the lever 33 will cause the cylinder again to rotate.
Having now particularly described, and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what 1
claim is ;-
1. The combination and arrangement of parts forming the mechanism for
controlling the movements of shuttle-boxes substantially as herein specified.
2. In mechanism for controlling the movements of loom shuttle-boxes, the
combination of a pattern cylinder arranged to have rotary, reciprocatory and
lateral movements imparted to it, means for imparting said movements to said
cylinder, a series of levers arranged to move over the surface of said cylinder and
means for effecting the movements of these levers substantially as and for the
purposes specified.
3. In mechanism for controlling the movements of loom shuttle-boxes, the
combination of a pattern cylinder, levers for contact with said cylinder, a ratchet
arranged to be brought into operation by said ievers for imparting motion to said
cylinder, cam mechanism with ratchet and holding devices for operating said cam
mechanism and connecting parts for disengaging said cam operating mechanism
substantially as herein specified.
