Improvements in Shuttle Guards for Looms.
I, WILLIAM SARGENTSON of Glenthorne, Padfield, Hadfield in the County of
Derby, Merchant and Manufacturer, 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 an improved Shuttle Guard for looms which possesses
the advantages of cheapness, certainty in action, simplicity, and that whilst it is
easily displaced for piecing, it returns into its working position automatically on
the first forward movement of the lathe.
The construction of my new Shuttle Guard is illustrated by the accompanying
drawings in which:
Figure 1 represents a partial plan with the shuttle guard displaced for piecing,
and Figure 2, a similar plan with the guard in position.
Figures 3 and 4 shew cross sections along the lines y Figure 1, and -z
Figure 2, respectively.
A is the lathe top and G, the shuttle guard which consists simply of a length of
wire having at each end a part g, returned at a right angle. In the illustrated
application of my guard, I bore near the ends of the lathe top, the two diagonal
holes H H in such positions that they can freely receive the ends gg. These ends
means may be employed for preventing the guard from dropping too low and from
dropping out of its holes altogether. For instance, I may use the non-rotatable
bush B, which is separately shewn in elevation on a larger scale by Figure 5. It
is also shewn in cross section in Figures 3 and 4. It consists of a tubular part B,
the front end of which is shaped to be flush with the front of the lathe top, and two
wings b, the sole function of which is to prevent the turning of the bush in the
hole H. Or, short lengths of tube may be provided in substitution for the bushes B,
and may be fitted in the holes and retained by means of perforated shields or face
plates fixed over the lower openings of the holes. Such a tubular or similar guide
These ends
is desirable to prevent the canting and jamming of the ends gg.
having been passed upwards through the holes, short pins may be placed in the
perforations gin g, so as to form stops which come into contact with the upper ends
of the bush guide B, and prevent the further descent of the guard. Other
equivalent stops may obviously be employed.
In use,
the guard is pushed into the higher position by the weaver when she
desires to piece. In this position it lies closely in contact with the lathe top as
shewn by Figures 1 and 3. If this slight projection should be objected to, the lathe
top can be longitudinally grooved, in which case the guard can be pushed into
the groove and be flush with the face of the lathe top when out of action.
If desired, a light catch may be employed tending to hold the guard in this
position by light frictional contact, but as I have not yet found this necessary I
have not shewn it in the drawings.
When the weaver is ready to restart the loom, it is not necessary for her to trouble
about the shuttle guard, because the first beat throws it instantly into the protective
position

page_text: In the case of wide looms, there may be one or more intermediate arms formed
upon the guard, precisely corresponding with the ends g, and each fitting in a
diagonal bush and hole corresponding with those in which the ends g fit.
In the case of iron lathe tops, and when holes cannot be formed through these
parts as herein before described, it may be possible to clamp wood or other blocks
upon the lathe tops and form the holes H through these blocks. In such cases it
will be necessary to make the ends g longer and to bend them downwards so as to
bring the guard into the position shewn by the drawings. I prefer however to
avoid such alternatives and to construct and arrange the guard as described with
reference to the Figures.
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:-
1. A shuttle guard for looms consisting essentially of a piece of wire or rod
having returned ends which are capable of sliding in or in connection with the
loom lathe top; constructed and arranged substantially as hereinbefore described
with reference to the accompanying drawings.
2. A shuttle guard for looms, constructed and arranged substantially as here-
inbefore described and as illustrated by the accompanying drawings.
Dated this 10th day of June A.D. 1091.
