IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1864

page_text: PROVISIONAL SPECIFICATION left by Richard Longden Hattersley and
James Hill at the Office of the Commissioners of Patents, with their
Petition, on the 30th November 1864.
We, RICHARD LONGDEN HATTERSLEY, of Keighley, in the County of York,
5 Machine Maker, and JAMES HILL, of Cross Hills, also in the County of
York, Overlooker, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN LOOMS FOR WEAVING," to be as follows:-
This Invention relates, firstly, 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 books 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
books 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
have as many hooks placed thereon at suitable distances apart as the
greatest

page_text: number of compartments to be turned in any single action required. 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
thicknesses 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
correspond, 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 H¹ 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 the 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, one or two tappets acting on one of 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 one of 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 of compartments of the shuttle boxes. These are so con-
structed and applied as to be readily put in operation as required.

page_text: In another modification of this part of our Invention we operate upon the
pusher 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.
Another part of the Invention has reference to a method of working the
healds or heddles, and consists in the application of single or double spring
catches inserted or attached to the upright treading rods or bars which are
connected to the top and bottom levers for raising and depressing the healds
or beddles; such catches being brought into position to be operated by the
ordinary treading levers by means of jacquard or other indicating apparatus.
