Improvements in or relating to Sewing Machines.
I, HARRIET RUTH TRACY, of 58, Brondesbury Villas, Maida Vale, in the County
of Middlesex, Gentlewoman, do hereby declare the nature of this invention to
be as follows:-
This invention relates to improvements in the form and method of construction
of loop-takers or shuttles for sewing machines, which have loop-engagers and
loop-retainers at their periphery, the object being to enable the loop-engagers
and retainers to be changed at will to suit work on different kinds of material
and also to simplify and cheapen the construction of such loop-takers.
The invention is more particularly adapted to rotary loop-takers of the class
described in a previous application for a patent made by me No. 22946 dated
Nov. 1st 1898, but is also applicable to other forms of loop-taker.
It has been the practice hitherto to form the loop-engaging hooks and loop-
retaining projections integral with the body of the loop-taker by cutting away
portions of the periphery of the same forming recesses or the like.
In carrying out my invention I form each loop-engaging hook and loop re-
taining projection out of a separate piece of metal and fix them to the periphery
of the body of the loop-taker by means of a screw or screws or other convenient
device.
Preferably each loop-engaging hook and its adjacent loop-retainer are con-
structed in one but they may each be formed separate and affixed to the loop-
taker by independent devices.

I, HARRIET RUTH TRACY, Gentlewoman, of 58, Brondesbury Villas, Maida Vale,
in the County of Middlesex, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
―
This invention relates to improvements in the form and method of construction
of that class of loop-taker or shuttle for sewing machines at the periphery of
which loop engagers and loop retainers are formed, the object being to enable
the loop engagers and retainers to be changed at will to accommodate work on
different kinds of material, and also to facilitate and cheapen the construction
of such loop takers.
The invention is more particularly adapted to that class of rotary loop-takers
which take up their own slack but is also applicable to other forms of loop-taker.

page_text: It has hitherto been the practice to form the loop engaging hooks and loop
retaining devices integral with the body of the loop taker or shuttle by forming
them as recesses or the like in the periphery of the same. In carrying out my
invention I forin each loop engaging hook, and loop retaining surface or pro-
jection apart from the body of the looptaker out of a separate piece of metal,
and fix them to the periphery of the body of the loop taker by means of a screw,
screws, or other convenient device.
In the accompanying drawings
Figure 1 is a side view of a rotating loop-taker constructed according to this
invention, and
Figures 2 and 3 are details showing different constructions.
Referring to Figure 1, A is the body of a loop-taker or shuttle, capable of
holding a cop, reel or bobbin of thread, preferably circular in shape, and pro-
vided, at its periphery with appendages B, attached thereto in any convenient
manner say by screws B. Each appendage B is formed with a loop receiving
opening B² one wall of which terminates in a hook 'or pointed projection B³ to
engage the loop of the needle thread and bring it within the opening B2; the
other wall or side B constitutes the loop retainer.
The appendages B may be varied in shape to suit different stitches and classes
of work and may be secured to the body of the loop-taker in any convenient
männer. An alternative form is shown in Figure in which the appendage B
is provided with lugs B³ to receive the screws B¹.
Preferably the appendage B is formed in one piece as shown in Figures 1
and 2, but if desired the loop, engager B³ may be made separate from the loop
retainer B and each secured independently to the body A of the loop-taker as
- shown in Figure 3.
If desired the loop-taker may be provided with depressions in its periphery
within which the appendages may be secured.
When thus removably attached to the body of the loop-taker the appendages B
can be readily changed according to the kind of material to be sewn or for other
reasons, but if desired they may be irremovably fixed on to the loop-taker body,
the loop-taker being constructed more readily and cheaper by this method than
by forming the loop receiving openings in the body of the loop-taker, as has
.been the practice hitherto.
It is evident that the form of the loop-taker body and the form and number
of the appendages may be varied in many ways without departing from the spirit
of this 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. A shuttle or loop-taker for sewing machines having appendages which are
removable for the purpose described.
2. A shuttle or loop-taker for sewing machines having one or more appendages
for the purpose described attached to and extending beyond its periphery.
3. A shuttle or loop-taker for sewing machines having attached to its peri-
phery one or more appendages, each comprising a loop engager, and a loop re-
tainer forming between them a loop receiving opening substantially as described
or as illustrated in Figure 1 and Figure 2 and Figure 3 of the accompanying
drawings.
