IMPROVEMENTS IN SHUTTLES FOR WEAVING
Year: 1885

Shuttle Maker do hereby declare the nature of my invention for IMPROVEMENTS
IN SHUTTLES FOR WEAVING to be as follows:-
Hitherto, the two pullies at each end of the shuttle, on which they run, have
been fast to each other, or fast to the axle on which they revolve; but I propose to
have them separate, so that one will revolve indipendent of the other, and mount
the same on a fixed axle, which is fastened by means of a screw or bolt which
screws or passes through it, and through the shuttle, and has a nut on the top side
of the shuttle to secure it; the ends of the axles are fitted into the shuttle to give
them stability and prevent them twisting. In place of the axles being fastened, to
the shuttle by bolts, the axle may pass through the shuttle and be screwed into
the same, and the two pullies on the axle revolve indipendent of each other. By
these means the wood of the shuttle will not require to be cut away between the
two pullies which leaves the shuttle considerably stronger. The metal plates
which protect the sides of the shuttle hitherto have been tapered towards the end,
and the ends formed straight or flat, but I propose to form them when tapered
towards the end, with the ends circular, or round, and thus leave them free from
objectionable points or corners.

page_text: I SAMUEL WHITWORTH of 3 East Street Rochdale in the county of Lancaster
Shuttle Maker do hereby declare the nature of my invention for IMPROVEMENTS
IN SHUTTLES FOR WEAVING and in what manner, the same is to be performed, to
be particularly described and ascertained in and by the following statement :-
The object of my Invention is to make the two pullies at each end of the shuttles
used for, weaving woollen cloth and other strong fabrics, so that they will revolve
independently of each other by which means the shuttle is made stronger and
friction reduced. The taper ended metal side plates for protecting the sides of the
shuttle are rounded at the ends so as to dispense with the objectionable points or
corners, And in order that my Invention may be fully understood and readily
carried into effect I will proceed to describe the accompanying drawing, reference
being had to the letters and figures marked thereon. Fig. 1 shows the underside
of a shuttle with the pullies, fixed as proposed. Fig. 2 is a side elevation of a
shuttle with the pullies fixed as proposed and the taper ended metal side plate with
the rounded ends. Fig. 3 is a section of a shuttle on a larger scale showing how
the pullies and the shaft on which they revolve are attached to the shuttle and
Fig. 4 is a section of a shuttle also on a larger scale showing another way of
attaching the pullies and the shaft on which they revolve to the shuttle. a and a¹
are two pullies, at each end of the shuttle b, which revolve independently of each
other on the shaft c (see Fig. 1. 2 and 3) which is fastened to the shuttle by the
screw d, which passes through the shaft c and is screwed into the wood of the
shuttle so as to press the centre and the ends of the shaft c against the shuttle and
when screwed home to its place the nut e is screwed on to the end of the screw d
so as to more securely fasten it. The ends and centre of the shaft c are bedded
into recesses or grooves f formed in the shuttle which prevent its being knocked
out of its proper position: In Fig. 4 the shaft g on which the pullies revolve passes
through the shuttle, and is made smaller at one end than at the other, and screwed
into the wood of the shuttle at two places as shown, a flat or groove is formed on
the top of the shaft g on which the washers i are fitted so as to prevent them
turning round on the shaft; by these means the wood of the shuttle between the
two pullies does not require to be cut so much away, and the shuttles are made
stronger, and with the two pullies revolving independently of each other they will
not work against each other if by any means one pulley gets smaller than the
other, and thus friction be reduced.
h Fig. 2 shows a taper ended metal side plate, with the ends rounded so as to
dispense with the objectionable points or corners, these side plates may be all in
one piece as shown, or in two pieces, one at each end as preferred.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1st Having the two pullies at each end of the shuttle (which carries the shuttle)
so that they will revolve independently of each other substantially as herein
described.
2nd Fastening the shafts on which the pullies revolve that carry the shuttle, to
the shuttle substantially as herein shown and described in Fig. 1. 2 and 3.
3rd The shaft g substantially as shown and described in reference to Fig. 4..
4th Rounding the ends of the taper ended metal side plates substantially as
herein described.
