Improvements in Self-threading Shuttles for Looms.
I, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co., Patent Agents,
45 Southampton Buildings, 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 :-
One feature of this invention is a spiral of wire constituting an eye one end of
which is bent upwardly to form a guiding pin for the thread, the other end being
bent inwardly to attach it to the shuttle.
Another feature of this invention is that the guiding pin is in a recess which
has a slot leading from it through which the thread must pass in sliding down
the pin.
In the accompanying drawing
Figure 1 is a top view of the improved shuttle;
Figure 2 is a side view,
Figures 3 and 4 are like views of a portion of the shuttle drawn to an enlarged
scale.
Figure 5 illustrates the combined eye and guiding pin.
Like letters of reference indicate corresponding parts in the several figures of
the drawing.
In the drawing showing the best form of this invention A is the shuttle body
having the bobbin B, C is a space through which the thread passes to the eye.
In the space C is a guide D designed to keep the thread away from the wood of
the shuttle and provide a smooth surface over which the thread runs.
E is the customary perforation in the shuttle which communicates with the
recess F and the space C.
G is a piece of wire which is formed in a spiral at G¹ bent upwardly through
recess F to form the guiding pin g³ and bent inwardly at g' to enter the body of
the shuttle and secure it in place.
Between space C and recess F is a slot H of sufficient width to allow the passage
of the thread, the sides of recess F converging easily toward the slot offering no
impediment to the thread as it slides down the guiding pin.
To thread the shuttle the thread is looped over the guiding pin and then
pulled back through the slot toward the rear of the shuttle causing the bight of
the loop to slide down upon the pin 92 until it is within the reach of the operator,
as shown in Figures 1 and 3.
The invention is an eye and guiding pin in one piece which can be readily
applied and is inexpensive.
In other shuttles of this class the recess for the pin opens directly to the bobbin,
o that the slacking of the thread sometimes results in its getting caught on the pin
causing great inconvenience.
By the present invention, however the pin is protected by the partition between
the two recesses so that no engagement of the thread with the pin is possible
when the shuttle is in use, the narrow slot permitting the thread to be drawn over
he pin in threading the shuttle; but preventing all danger of the slack thread
getting caught on the pin.

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to
me by my foreign correspondents, 1 declare that what I claim is :-
:-
1. In combination, shuttle body A, perforated at E and recessed at F, and a
spiral of wire forming an eye and lying in perforation E, with an upwardly bent
portion thereof extending into a recess F in the shuttle body and constituting a
guiding pin, and a bent portion to secure the spiral to the shuttle body, substantially
as described.
2. A shuttle-body having a recess C, eye E, space F and slot H, in con-
bination with the guiding pin 92 leading to the shuttle eye, all substantially as
described.
Dated this 4th day of April 1893.
