IMPROVEMENTS IN SHUTTLES AND BOBBINS
Year: 1884

page_text: We THOMAS TWEEDALE, Surgeon, and CHARLES LAKEMAN TWEEDALE, Gentleman,
both of Crawshawbooth near Rawtenstall, Lancashire, do hereby declare the nature
of said Invention for IMPROVEMENTS IN SHUTTLES AND BOBBINS; to be as follows:
Our invention:relates to improvements in shuttles and bobbins, the object of our
improvements being to dispense with the ordinary side clips or wires generally
employed to hold the bobbin in position on the shuttle peg, and instead to hold the
bobbin by the top spring, and to automatically lock it in position when its peg is
pressed down into the shuttle.
To effect this we employ a shuttle peg the top spring of which is raised by means
of its extended end when the peg is pressed down into the shuttle. This form of
peg is fully described in the Specification to Letters Patent granted to Thomas
Brooks and Thomas Tweedale on the 28th day of March A.D. 1883 N° 1573, but
instead of having the top spring raised or arched we prefer to use a top spring
which lies flat or nearly so on the peg or tongue and we bend or form a projection
on the upper surface of the top spring near the head or base of the peg.
We form an annular recess, groove, or hollow in the body of the bobbin at the
larger end with a flange round the opening at the base.
When the bobbin is pushed on to the raised shuttle peg its flange passes over the
projection on the top spring and when the peg is pressed down into the shuttle the
projection on the top spring enters the annular recess and so holds the bobbin and
locks it firmly in its position.

both of Crawshawbooth, near Rawtenstal, Lancashire, do hereby declare the nature
of said Invention for IMPROVEMENTS IN SHUTTLES AND BOBBINS, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-:
Our invention relates to improvements in shuttles and bobbins, the object of our
improvements being to dispense with the ordinary side clips or wires generally
employed to hold the bobbin in position on the shuttle peg and instead to hold the
-bobbin by the top spring, and to automatically lock it in position when the peg is
. pressed down into the shuttle.

To effect this we employ a shuttle peg the top spring of which is raised by means
of its extended end when the peg is pressed down into the shuttle. This form of
peg is fully described in the Specification to Letters Patent granted to Thomas
Brooks and Thomas Tweedale on the 28th day of March A.D. 1883 N° 1573 but
instead of having the top spring raised or arched we prefer to use a top spring
which lies flat or nearly so on the peg or tongue, and we bend or form a projection
on the upper surface of the top spring near the head or base of the peg.
We form an annular recess, groove or hollow in the body of the bobbin at the
larger end with a flange round the opening at the base.
When the bobbin is pushed on to the raised shuttle peg its flange passes over the
projection on the top spring and when the peg is pressed down into the shuttle the
projection on the top spring enters the annular recess and so holds the bobbin and
locks it firmly in its position.
And in order that our Invention may be fully understood and readily carried
into effect we will describe the accompanying Sheet of Drawings, reference being
had to the figures and letters marked thereon.
Figure 1 is a sectional elevation with the peg down. Fig. 2 a similar view with
the peg raised and Fig. 3 a plan of a shuttle and bobbin to which our improve-
ments are applied and Fig. 4-is a sectional elevation of a bobbin in which an
annular groove is formed according to our Invention.
Similar letters refer to similar parts throughout the several views.
a is the shuttle and 6 the shuttle peg the top spring b₁ of which is formed with a
bend or projection b and an extended end 6 by which it is raised: c is the bobbin
in which we form a hole or hollow c¹ as shown in Fig. 1, or two such holes or
hollows as shown in Fig. 2, or an annular groove or recess c³ as shown in Fig. 4.
The bobbin c is pushed on to the raised shuttle peg b which is then pressed down
into the shuttle a, the projection 62 on the top spring 61 being raised by the
extended end 63 enters the hole or hollow c¹ (Fig. 1) or one of the holes or
hollows c¹ (Fig. 2) or the annular groove or recess c² (Fig. 4) and thereby firmly
holds the bobbin c and locks it in its proper position.

page_text: Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed, we declare that what
we claim is
The combination with a shuttle peg formed with a bend or projection on the top
spring, the said top spring when pressed down into the shuttle being raised by
means of its extended end, of a bobbin formed with a hole, hollow, or annular
groove or recess to receive the said bend or projection, substantially in the manner
and for the purposes herein described and as illustrated by the Drawings annexed.
