PROVISIONAL SPECIFICATION.
Improvements in Loom Shuttle-boxes, and in Means for Operating
the same.
I, FREDERICK WADDINGTON of Sunny Mount, Keighley in the County of
York, Machine Maker, do hereby declare the nature of this invention to be as
follows:-
"
This invention relates to the construction or formation of "rotary shuttle-boxes'
for looms and to means for operating the same, the latter being also applicable for
use in the operating of those shuttle-boxes known as "drop-boxes."
In accordance with my invention I arrange four compartments for the reception'
of the shuttles, around a common axis in such a manner as will keep them as close
to said axis as ever possible and in doing this the divisions in the shuttle-box form'
in each case the bottom of one compartment and the side wall of the compartment,
adjoining, thus the other side wall may carry a lever known as a sweller by which
I am enabled to use a stop-rod and thus a "fast-reed" loom having a rotary shuttle
box may be produced with well known advantages.
The picking mechanism known as "under-pick" may also be employed in
connection with iny formation of rotary shuttle box and this is the kind I prefer-
ably use when boxes for large shuttles are employed, although the well known
over-pick" mechanism may be applied if desired.

.
The mechanism for operating the shuttle-box consists of an eccentric mounted
to be rotated on bearings carried by the framework of the loom by segment rack
and pinion mechanism.
This eccentric is made to operate a sliding piece which carries another eccentric
and its operating parts, this latter eccentric being arranged to move another slide
so that this may thus have a compound or differential movement imparted to it by
which means on this last mentioned slide being coupled, as by rous, toothed
segment, gearing wheels and shafts, to the rotary shuttle box, this said shuttle box
may be rotated through the space of one, two, three or even four of its compartments
as said eccentric and slide mechanism may be adjusted, regulated and produced to
effect in this manner any shuttle in the series of four may be brought into position
for operation as desired.
By coupling the eccentric and slide mechanism to a suitably formed lever, this
latter may be made to operate a tier of shuttle boxes raising them and lowering
them to bring any compartment in line with the lay or shuttle race as may be
indicated by the pattern surface mechanism.

the same.
I, FREDERICK WADDINGTON of Sunny Mount, Keighley 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 :-
"
This invention relates to the construction or formation of "rotary shuttle-boxes
for looms and to means for operating the same, the latter being also applicable for
use in the operating of those shuttle-boxes known as "drop-boxes."
In the accompanying sheets of drawings which are illustrative of my
invention;-
Fig. 1 is end elevation of a shuttle-box made in accordance with my invention.
Fig. 2 is a similar view of said shuttle-box to that illustrated by Fig. 1, but
shows same carrying its full number of shuttles, as also its relative position with
certain of the parts for operating in connection with it as is hereinafter explained.
Fig. 3 is a front elevation of the parts shown by Fig. 2 and as seen in the
direction of the arrow a.
Figs. 4 and 5 are similar views to Figs. 1 and 2 but illustrate modifications
hereinafter described.
Fig. 6 is a front elevation of certain of the parts shown by Fig. 4.
Fig. 7 is end elevation of a portion of a loom illustrating the application of my
improved box-operating-mechanism.
Fig. 8 is a view of said parts shown by Fig. 7 as seen from above.
Fig. 9 is a front elevation of certain of the parts shown by Fig. 7.
Fig. 10 is a diagram illustrating the method that may be followed in using my
improved mechanism for operating "drop-boxes."
Fig. 11 is a section on line A B of parts shown by Fig. 7.
Figs. 7 to 11 inclusive, are drawn to a reduced scale as compared with the other
figures.
Like letters and figures of reference indicate like parts throughout the several
views, in which only such portions of the framework are shown as are necessary to
illustrate the application of my invention.
In accordance with my invention I arrange four compartments 1, 2, 3, and 4
forming my improved shuttle-box 6 so that same may receive four shuttles c c¹ c
and e³, and these compartments 1, 2, 3 and 4 occupy such relative positions around
a common axis d as will keep them as close to said axis d as ever possible by which
means each of the divisions or partitions 61 62 63 and 6 forms the bottom of
one compartment and the side wall of the compartment adjoining (for example the
partition forms the bottom of the compartment 1, or that part of same on which
the bottom of the shuttle e rests, while it also forms the back or side wall of the
compartment 2 against which the shuttle c¹ is forced by the swell lever or
"sweller",) by which I am enabled to mount the swellers ƒ ƒ ƒ2 and f³ to
operate in connection with said shuttles c c¹ c² and c³ thus a loom having this rotary
shuttle-box may be fitted up with a stop-rod g which acts in the well known manner
and permits the employment of what is known as a "fast reed" so that all the
benefits incident. to the use of rotary shuttle-boxes, as the features they lend or
afford for their operations to be carried out at a high rate of speed, as well as
those incident to the use of a fast reed, as increased strength etc., are thus
secured.
The picking mechanism well known as "underpick" may also be employed in
connection with the shuttle-box constructed as above described and this is the kind

page_text: "
I preferably use when boxes for large shuttles are being used in which case the
picker h (see Fig. 2) extends, horizontally, although the well known "over pick
mechanism may be applied if desired, and in this case the picker h¹ (see Fig. 5)
extends vertically.
The mechanism for operating the shuttle-boxes consists of an eccentric k mounted
on bearings m fixed to the end frame n so that it may be rotated by a pinion o and
segment rack p, this said rack p deriving its motion from any suitable motor part
of the loom but preferably from mechanism governed or controlled by the pattern
surface forming part of the heald operating mechanism; these parts being old and
well known.
The eccentric transmits motion to the sliding piece 9 upon which are mounted
another eccentric or crank k' and the pinion o¹ and rack p' for operating said
crank k while this latter transmits motion to another sliding piece g¹ by which
means this said piece q¹ may be moved through varied stages indicated at s s¹ 82 83
Fig. 7, that is to say, should the eccentric alone be operated to move from its
position shown in said Fig. 7 the jointing pin in the piece 91 will move from its
position at to that at s³, or should the crank k¹ alone be moved at this time then
the movement of the pin would be from its position at sa to that at s', while further,
should both of these eccentrics k and k¹ be operated then said piece q' would
be moved from its said positions to that at s, and this varied movement may be
transmitted to the shuttle-box b through the medium of the rod t, toothed
quadrant & pinion t³ (to which the bevel wheel t³ is secured,) said bevel wheel t³,
the bevel wheels t, to and to and the shaft 17, thus this said shuttle-box b may be
rotated through the space of one, two or three of its compartments by which any
one of the four said compartments may be brought into position as is desired or as
said eccentric and slide mechanism may be adjusted, regulated and produced to
effect.
To enable the shaft t' to oscillate with the slayboard without thereby imparting
motion to the box ba ball and socket joint u is formed and a clutch coupling u¹ is
used to connect said shaft t' to its wheel tt.
When my improved shuttle box bis operated by the mechanism last before
described I preferably form a pivotal projection to operate within the bearings vl
at its inner eud as shown by Fig. 3, by which it is enabled to revolve freely, since
the shots of weft that may be wound around this pin as the box b revolves are
always brought back into their proper positions on the return of said box 6 as will
be well understood, while should the mechanism for operating said box 6 be of the
kind that would impart an endless movement thereto as would the kind of
mechanism most commonly employed for operating rotary shuttle boxes, then
I dispense with the pin and fix an annular piece around or upon the said inner
end of the box b as shown by Figs. 4 and 6 and this piece rotates in the
bearings which may or may not carry antifriction rollers » as may be thought
the more desirable.
By employing the eccentric and slide mechanism herein before described and
coupling same to a suitably formed lever as the lever to (see Fig. 10) this
latter may be made to operate a tier of shuttle boxes x, raising them and lowering
them to bring any compartment in line with the lay or shuttle race as may be
desired.
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 I
claim is ;-
1. In a loom the combination of a rotary shuttle-box constructed as described,
with means for operating same substantially as specified.
2. In a fast reed loom the combination of a rotary shuttle-box, swell-levers
carried by same and a stop rod for operating in connection with said swell-levers
substantially as set forth.
3. In a loom the combination of eccentrics, slides, racks and pinions and means

page_text: for connecting same to enable them to transmit motion to rotary shuttle-boxes of
said loom substantially as specified.
:
4. In a loom the combination of eccentrics,,slides, racks and pinions and means
for connecting same to enable them to transmit motion to the "drop-shuttle-
boxes" of said loom substantially as specified.
