An Improved Shuttle Guard for Use in Looms for Weaving.
I, RICHARD BROWN, of 10 St. Christopher's Road, Preston, in the County of
Lancaster, Pattern Maker and Draughtsman, 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 consists of a sliding connection from the lathe or slay to the stopping
and starting spring handle, whereby the motion from the spring handle in stopping
or starting the loom moves a bar attached to the lathe or slay longitudinally and by
means of a swell and levers gives automatic action to a hinged rising and falling
shuttle guard. One end of the said sliding bar is made at right angles from the lathe
or slay which passing into an eye or slot on spring handle forms a direct connection,
which connection is kept up when the loom is in motion by the sliding of the bar in
said eye or slot by the motion of the lathe or slay.
In the accompanying Drawings Fig. 1 is a front view and Fig. 2 an end view of
part of a loom lathe or slay having my improved shuttle guard apparatus as above
described applied thereto.
a is the starting and stopping spring handle which comes in contact with an arm b
projecting at right angles from the sliding bar e mounted in bearings d d. The sliding
par e carries a connection or bracket e having a diagonal or inclined slot or swell f
hrough which passes the finger or lever g (see Fig. 2) pivotted or hinged on a fixed
centre at and jointed at i to the bush j fastened on the vertical rod k by means of
the screw nuts it. The upper end of the rod k is jointed to the free end of an arm m
pivotted at n to the bracket o fastened to the front of the slay cap p. The arm m is
fast to and operates the bar 9 which carries at the other end of the bracket a bush r
through which passes a spindle s provided with a screw nut t and an elastic or leather
washer u at its upper end its lower end carrying a cap or casting to which is fastened
the guard rod w which is preferably of the section known as half-round" with the
flat side facing the shuttle race. An end bracket o¹ is also provided with a bush »
sliding spindle s screw nutt and washer u and any convenient number of other inter-
mediate brackets of corresponding construction may be provided according to the
width of the loom. A spiral spring is interposed between the bush and the cap v as
shown, this arrangement permitting of the guard rod being raised or lifted up out of
the way when the loom is in motion in order to observe the flight of the shuttle or
for other purposes.
Another spiral spring a is fastened at one end to the bracket e
and at its other end to the bearing d' (shown in dotted lines in Fig. 1) and exercises a
pulling influence on the bracket e and sliding bar c so as to keep the pivotted lever g
hard up in the uppermost part of the diagonal slot f.
As shewn in the drawings the apparatus is in the position which obtains when the
loom is in motion. When however the loom is stopped by reason of the spring
handle a having been moved to the left (as shewn in dotted lines in Fig. 1) the sliding
bar c and bracket e will be correspondingly moved thereby causing the pivotted finger or
с

page_text: lever g to be pressed downwardly in the diagonal slot f and to move the vertical rod k
and the guard rod w to the position shewn by dotted lines in Fig. 2; the guard rod
being pressed up against the face of the slay cap p out of the way. When the loom
is again started the apparatus returns to its working position as first hereinabove
described as will be well understood.
Where the construction of the loom will not conveniently allow of the arrangement
of projecting arm 6 coming directly in contact with the spring handle a as shewn a
bracket or arm fastened to the spring handle and bent forward so as to meet and be
opposite to the projecting bar during the inward and outward movement of the slay
may be employed.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
In looms for weaving the use or employment of shuttle guard apparatus in which
the ordinary movement of the starting and stopping spring handle causes the guard
rod of such apparatus to be moved through the medium of a sliding bar and a connec-
tion thereon having a diagonal slot and a lever or finger working therein and hinged
or pivotted at one end to a fixed centre or fulcrum and jointed at its other end to a
vertical rod all being arranged substantially as described and shewn in the drawings.
Dated this 11th day of August 1888.
