Improvements in Mechanism connected with Rotary Shuttle Boxes
of Looms.
We, JOHN CHARLES Hamer, of Hope and Withins Mills, Radcliffe, in the
County of Lancaster, Cotton Manufacturer, and PETER TWIST, Mill Manager,
of 23 Knowles Street, Radcliffe aforesaid, do hereby declare the nature of this
invention to be as follows
-
This invention relates to mechanism for operating the pattern cylinder of rotary
shuttle boxes of looms for weaving, the object being to effect the required changes
of the position of the card, the box, and shuttle cells, so as to bing the required
shuttle into line with the race and shed by use of a minimum number of cards.
According to this our said invention, we mount the caid cylinder in slotted
guides, and by means of a link, connect the upright arm of a bell-crank or lover
with the said cylinder the other or horizontal ain of the lever extends over and
18 controlled by a pattern chain, so that the card cylinder is caused to slide in its
bearings backwards or forwards, whereby double service is obtained from each
card by utilizing its width twice or more, the necessary changes and reversals
being effected by a comparatively small number of cards. Any of the ordinary
devices for tuining the pattein cylinder may be employed.

We, JOHN CHARLES HAMER, of Hope and Withins Mills, Radcliffe, in the
County of Lancaster, Cotton Manufacturer, and PETER TWIST, of 23 Knowles
Street, Radcliffe aforesaid, Mill Manager, 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 mechanism for operating the pattern cylinder of rotary

According to this our said invention, we mount the card cylinder in slotted
guides, and by means of a link, connect the upright arin of a bell-crank or
with the said cylinder, the other or horizontal arm of the lever extends over
and is controlled by a pattern chain, so that the card cylinder is caused to slide in
its bearings backwards or for wards, whereby double service is obtained from each
card by utilizing its width twice or more, the necessary changes and leversals

devices for turning the pattern cylinder may be employed.
Such being the nature and object of our said invention, the following is a
complete description of same, reference being had to the accompanying diawing,
which is an end elevation of the improved mechanism for controlling the rotary
shuttle boxes and for operating and controlling the card cylinder in such boxes.
According to this our said invention, we mount the caid cylinder 1 in a bucket 2
carried in slotted guides 3, 3, and the bracket 2 18 by link 4 connected to the
upright arm of a bell-crank or lever 5 mounted on a fuletum stud 6 On the
end of the horizontal aim of the lever 5 is mounted a bowl or runner 6* resting ou
a pattern cham 7, the barrel of which is operated by a catch or pawl 8 mounted on
the top of the lever 9 carried on the fulcrum 10, and operated in one direction by
the tappet 11, and in the opposite direction by the spring 12. The top of the
upright arm of the bell-crank level 5 15 by link 13 connected to the end of the
level 14, free to rook on its fulcium 16, the other end of said level 14 being
connected with the level 15, on which is the peg or stud 16 for pulling the
pendant catches 17, 17 into line with the ratchet teeth 18 on the axis of the card
cylinder 1.
The card cylinder 1 is of double width or has two rows of holes in it, and when
the mechanism is in operation, the cylinder 1 will be slided to and fio, so that n
double service is obtained from each card by utilizing its width twice or more, the
necessary changes and reversals being effected by a comparatively small number of
cards.
The card cylinder 1 is preferably turned in one direction on the other by the
pendant catch levers 17, 17 which engage with one or other of the ratchet
wheels 18, the teeth of one of which point in one direction, and the teeth of the
other in the opposite direction. The catches 17, 17 are by the pin 16, lever 15,
and connections, moved when the card cylinder 1 is moved in its slide.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
(1.) The general construction, arrangement, and combination of parts constituting
the improved mechanism for controlling the shuttle boxes of looms for weaving,
as and for the purpose herein described and substantially as illustrated by the
annexed diawing.
(2.) The caid cylinder 1 free to slide in its bearings, link 4, cranked lever 5,
and pattern chain 7, all in combination, as and for the purpose herein described,
and substantially as illustrated by the annexed drawings.
