IMPROVEMENTS IN SHUTTLES
Year: 1884

page_text: I THOMAS TWEEDALE, of Crawshawbooth, near Rawtenstall, Lancashire, Surgeon,
do hereby declare the nature of said Invention for IMPROVEMENTS IN SHUTTLES,
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 render shuttles stronger and more durable and
to simplify the method of fastening the spring which governs the shuttle peg or
tongue to steady the peg and to reduce the number of pins employed and to permit
the spring which governs the shuttle tongue to be taken out of the shuttle without
removing the pin which fastens the said spring in its place.
To accomplish this I apply to the head of the peg or tongue a governing spring
of a peculiar shape at the same time shaping the shuttle in such a manner as to
keep and support the governing spring in its place by the aid of one pin only.
Also I shape the head of the tougue so that when it is closed down into the shuttle
one extremity of the said governing spring performs the function of a stop having
a durable broad bearing surface while the other extremity performs the function of
a common shuttle spring, namely that of keeping the tongue closed down into the
shuttle.
And in order that my Invention may be fully understood and readily carried into
effect I will proceed to describe the accompanying Sheet of Drawings reference
being had to the Figures and letters marked thereon.
Fig. 1 is a sectional elevation and Fig. 2 is a plan of a shuttle to which my
improvements are applied and Figs. 3, 4, 5, 6, 7, and 8 are views of the spring and
tongue.
Similar letters refer to similar parts throughout the several views.
a is the body of the shuttle in which is fixed the pin b; c is my improved spring
which is put into its place by holding it in a vertical position (when the shuttle is
in a horizontal position) and passing the shorter bent end between the pin b and
the body of the shuttle and then moving the spring into the position shown on
Fig. 1: the tongue d is then pressed into its place and the pin e inserted: the
tongue head is so formed as to come in contact with and press on that part of the
spring which bears against the pin 6 thus keeping the tongue steady while
the shuttle is at work. The dotted lines indicate the position of the tongue when
it is raised to put on or remove a cop.
When it is necessary to take out or put in the spring the pin e only need be
withdrawn.

page_text: I would have it understood that 1 do not limit myself to the exact details herein
described and shown as the form of the spring c and the position of the pin b.may
be modified or varied so long as the same results are obtained without departing
from the nature of my Invention.
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
1. The combination of parts forming the improved shuttle, substantially as
herein described and illustrated in the Drawings annexed.
2. The improved shuttle spring cas and for the purposes herein set forth.
3. A shuttle spring that forms a stop for the tongue head, substantially as herein
described and as shown.
