Improvements in Shuttles for Looms.
I, WILHELM SCHALCK of Elberfeld, Rhenish Prussia, Germany, Merchant,
Langestrasse No. 26 do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertaine:
in and by the following statement :-
The shuttles used by weavers generally are made of box wood or other hard
wood having the quality that it does not slit and shrink or bend.
The difficulty of procuring good pieces of suitable wood for the enormous
and steadily increasing demand of shuttles has caused the search for suitable
substitutes for wooden shuttles; iron or steel pressed shuttles have been introduced,.
but on account of their hardness they cause too much wear on the reed.
Now I have succeeded in producing a shuttle that has all the good and best
qualities of wooden shuttles without any of their drawbacks, at least when they are
inade of inferior quality of wood, or of wood having knots and parts of different
hardness at various parts.
I make my new shuttle of a combination of leather and wood or instead of
the leather I use a material being equally hard and that can be polished or
snoothed as well as leather, such as specially prepared vulcan fibre or also fibre of
plants. I prefer however a combination of leather and wood, because this combination
gets cheaper and can be more readily worked and shaped. The use of leather
alone does not recommend itself, because the leather alone too much subjected to
the influence of climate and temperature.
The manner of making my new shuttles will be best understood by means of the
accompanying drawing, in which
Figure 1 shows the shuttle as seen from the top side;
Figure 2 show the same as seen from the bottom side;
Figure 3 shows the shuttle seen at right angle from the two preceding views
(from the right side of Figure 5).
Figure 4 is a cross section along line III-III.
Figure 5 is a cross section along line 1-1.
Figure 6 is a similar section along line 11-11.
Figure 7 shows a modification in combining the different materials as seen in a
section when made at III-III.
The peculiarity of my new shuttle consists in the combination of wood and
leather or similar material which are glued together so as to form one solid and
durable mass. At the outside I place a layer of leather a, then comes a layer of
wood C and then again a layer of leather a' on each side and finally a layer of
wood C¹ in the middle (Figures 4 and 7). The layers may be arranged vertically
or horizontally. Fig. 7. I use by preference the first arrangement, though not
exclusively.
In Figure 6 the combination of the layers of wood and leather is shown in a
mixed way; the top and bottom of the shuttle are formed of layers of leather A, A;
between these are arranged the layers of wood and leather B B and C C.
My object is to form by this combination a body for the shuttle which can not
slit nor shrink, which is durable and not soon worn and which, especially presents
very smooth surfaces where it passes over the warp threads and along the reed, so
that neither of them will be injured by the flight of the shuttle along or across
them; for this reason I always arrange at the working sides a layer of leather,

page_text: this being the more durable and smoother material or at any rate less subject to
getting rough.
The other parts of the shuttle may be constructed in any convenient manner, so
the pin F for holding the spool is shown to turn on a pin G so that it can be
raised out of the shuttle itself for convenient sticking up of the reel.
I do not claim any construction of this sort as being new.
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
claim is:
The making of weavers shuttles, by glueing together layers of leather and wood
alternately, or of vulcan fibre in place of the leather combined with wood, this
combination forming the body of the shuttle to which are fitted the other accessories
completing the shuttle, in any approved manner, the whole as set forth and for the
purpose specified.
Dated this 6th day of August 1894.
