Improvements in Loom Shuttles.
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 :-
My invention relates to self threading shuttles, and consists in a shuttle, the
cylindrical eye of which has a curved guiding pin which extends outside (or nearly
so) of the eye inwardly through it and up into a recess near one end of the said
shuttle; the guiding pin being so curved that when the thread is looped over it,
the bight of the thread slips along the curved pin until the said bight has passed
down the pin to its lower end when it is far enough through the eye to be readily
seized by the fingers of the weaver.
In the accompanying drawing
Figure is a plan of a shuttle embodying my invention;
Figure 2 is a side view with portions broken away.
Figure 3 is a section on line 3-3 of Figure 1.
Figures 4 and 5 are views of the eye and curved finger detached.
A is the shuttle, and B the bobbin of the usual construction. The eye a is
cylindrical, and the curved guiding pin is secured at one end on or near the
outer surface of the eye a, as best shown in Figures 2 and 4; thence curving
slightly towards, and extending through the eye a, whence it curves upwards and
inwardly, its upper end standing free of the shuttle body but in the usual recess
formed near one end of the shuttle. A part of the cylindrical eye a is cut away as
it would in this case be useless.
In threading my new shuttle the thread from the bobbin B is carried about the
free end of the curved guiding pin bas shown in Figure 1; and as the free end of
the thread, which is on the right of this pin b, is pulled upon, the bight which is
in contact with the said pin slips from the free end thereof towards the fast end of
the same, coming to the position shown in Figure 2; that is, the bight of thread
extends through the eye a, and in such a position that the weaver can readily seize
it, and pull it out so that the free end of the thread will extend from the bobbin,
over the usual tension & and out through the eye a.
The curve of pin is such that the bight of thread about it, slides easily from
its upper end towards its fast end; and also such that the pin extends from the
outer surface of the eye up into the recess near the end of the shuttle.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
The above described self threading shuttle with the curved guiding pin b, fast
at one end to the cylindrical eye a, and extending through eye a, with its free end
in a recess near one end of the shuttle, substantially as described.
Dated this 19th day of May 1891.
