Year: 1864

and James Hill at the Office of the Commissioners of Patents, with
their Petition, on the 30th May 1864.
We, RICHARD LONGDEN HATTERSLEY, of Keighley, Machine Maker, and
JAMES HILL, of Cross Hills, Overlooker, both in the County of York, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
LOOMS FOR WEAVING," to be as follows:-
This Invention relates to means of operating rotary shuttle boxes, and one
part has reference to further improvements upon means or apparatus for' which
Letters Patent were granted to the aforesaid Richard Longden Hattersley,
dated May 24th, A.D. 1858, No. 1155, in the Specification of which portable
hooks or catches and taper rods or wedges are described, and which are shewn
to be capable of being actuated by jacquard or similar indicating apparatus for
operating rotary shuttle boxes, but which portable hooks or catches and taper
rods or wedges are only capable of turning the said shuttle boxes from any
one compartment which may be in line with the shuttle race to the next or
adjoining compartment.
Now the object of the present improvements is to enable any change to be
made in the shuttle boxes, or to "skip" from any one compartment to any
other compartment in the series, as may be required, and for this purpose
instead of having only one hook on each of the portable hooks or catches, we

page_text: have as many hooks placed thereon at suitable distances apart as the greatest
number of compartments to be turned in any single action requires. Also
we have the ends of the rods, pins, or needles which come in contact with the
cards of the jacquard or indicating apparatus constructed of different thick-
nesses or steps, the thickest part forming a shoulder to the next smaller part,
and so on, and the cards are prepared with different sizes of holes to corre-
spond, so that a small hole in the card will only admit the smallest size or end
of one of the rods, pins, or needles to enter to its shoulder, but the next larger
size of hole will admit of the next thicker portion of the rod, pin, or needle to
enter to its shoulder, and so on; the rods, pins, or needles being capable of
passing through the cards according to the size of hole in the card presented
to it, and thereby give more or less extent of motion in the turning of the
shuttle boxes through the operation of each taper rod, pin, or needle. We
also accomplish the same result by the use of levers attached or connected to
the rods, pins, or needles above described, instead of wedges; the portable
hooks or catches with more than one hook thereon can be attached to the
tappet lever A, or to the two levers H, I, shewn in the Specification of Patent
herein-before referred to.
Another part of the improvements has reference to operating rotary shuttle
boxes from or by the crank shaft or other shaft of the loom, also to a means
of locking or holding the shuttle boxes in correct position and for releasing
them at the proper time for change of compartments. This consists of pushers
operating on each side of a stud plate which is fixed on the spindle of the
shuttle box, and which pushers and stud plate are so formed and arranged and
provided with guards that the pushers can only be pushed or moved a certain
distance sufficient to move the shuttle boxes to the extent of one compartment
or a change to the adjoining compartment in either direction. Also a spring
catch is actuated simultaneously with either of the pushers to drop into a
notch of the stud plate and hold the shuttle boxes in position, and which is
lifted or removed from the notch so as to release the shuttle boxes when a
change is required to be made. Motion is communicated to the pushers by
levers actuated by cams or tappets applied on the crank or other shaft of the
loom, and if it be required to change from one compartment to the next at any
one revolution of the crank shaft two tappets with one action each on the
levers is sufficient, but if the change is required to move a distance of two
compartments, or skip over one compartment, then two tappets with two actions
'each on the levers are required in one revolution of the crank shaft, and
increased in the same manner for moving or skipping over any greater number

page_text: of compartments of the shuttle boxes. These tappets are so constructed and
applied as to be readily put in operation as required.
In another modification of this part of our Invention we operate upon the
pushers by connecting each pusher to an eccentric or crank pin, which is
caused to rotate by toothed gearing operated upon in a similar manner to the
tappets above described.
