COMPLETE SPECIFICATION.
An Improved Shuttle Guard for Looms.
I, LOUIS DIENST, of Elberfeld, in the Empire of Germany, Engineer, do hereby
declare the nature of this said invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
Statement:
My improvements relate to those shuttle guards which are fitted to the hand rest of
the lathe and arranged when turned back to lie upon the top of the hand rest while the
loom is stationary and to fall automatically into their working or protecting position
when the loom is set in motion; the object of my invention being to make the parts
stronger simpler and more rigid.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying Sheet of Drawings reference being bad to the
figure and letters marked thereon.
Figure 1 is a front elevation of part of the hand rest of a loom to which my
improved shuttle guard is applied. Fig. 2 is an end view of the same and Fig. 3 an
end view with the shuttle guard thrown back lying upon the hand rest out of the way
of the weaver and Fig. 4 is a similar view to Fig. 2 on a smaller. scale showing also
the shed formed by the warp.
a represents the hand rest of the loom, 6 the shuttle guard or rail preferably formed
of wood; to the hand rest one near each end are secured two brackets c each with a
peculiarly shaped loop c¹ and narrowed portion c²; two other brackets & secured to
the guard rail have projections d' which fit into the narrow portion c².
When the loom is in motion the guard brests in front of the shuttle race and it
remains locked in this position because the shaped projections d¹ fit in the narrowed
portions c² of the two brackets c, fixed on the hand rest a.
To release the guard for any purpose, when the loom is stopped, the weaver simply
raises it to move the parts d' into the enlarged portions of the loops c' which enables bim
to push the guard & back into the position shown in Fig. 3 a small plate or projection d
on each bracket d serving to protect the guard from the screw head when the guard is
thrown back. These plates d² also support the guard in such a position that it will
fall down automatically into the position indicated in Figs. 1, 2 and 4 as soon as the
loom is set in motion.
The construction of the brackets is such that they fit together and form a joint as
above described which locks and yet gives every facility for the movement of the
guard and dispenses with ordinary hinges, springs and catches which prove sources of
failure with other shuttle guards.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The use and application of brackets such as c and d arranged to lock a shuttle
guard when in its working and protecting position and yet enable it to be raised and
turned back upon the hand rest when required substantially as and for the purposes
specified.
2. The combination with the brackets c secured to the hand rest a, of the brackets d
secured to the shuttle guard b substantially as shown and described.
