SHUTTLE QUARD FOR LOOMS
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
1 ROBERT SMYTH at the Office for Patents, 323 High Holborn in the county of
Middlesex, Linen Manufacturer do hereby declare the nature of the said invention
for "SHUTTLE QUARD FOR LOOMS" to be as follows:-
The ordinary guard is a fixture and is in the way of the worker when tying
yarn etc. Now I make this improved shutt'e guard movable and connect it with
the starting mechanism in such a way that when the loom is at work the guard is
in place like the ordinary guard, but when the the loom is stopped the guard is
lifted out of the way. The guard is attached by suitable brackets preferably to the
hand rail and can nove or turn in these brackets-connected with it are suitable
rods and levers or equivalent mechanism which so connect it with the starting gear
that the guard is raised or lowered as the starting gear is moved. When down
or closed it keeps the shuttle from flying out; when raised it is out of the
workers way.

DEVIFICATION.
I ROBERT SMYTH at the Office for Patents 323 High Holborn in the county of
Middlesex, Linen Manufacturer do hereby declare the nature of my invention for
"SHUTTLE GUARD FOR LOOMS "and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:-
The ordinary guard is a fixture and is in the way of the worker when tying
yarn & Now I make this improved shuttle guard, movable and connect it with
the starting mechanism in such a way that when the loom is at work the guard is
in place like the ordinary guard, but when the loom is stopped the guard is lifted
out of the way. The guard is attached by suitable brackets preferably to the
handrail and can move or turn in these brackets; connected with it are suitable
rods and levers or equivalent mechanism which so connect it with the starting gear
that the guard is raised or lowered as the starting gear is moved. When down
or closed it keeps the shuttle from flying out; when raised it is out of the
workers way.
In the accompanying drawings Figure 1 is a front elevation of this device
Figure 2 a plan and Figures 3, 4 and 5. details.
A is the handrail and B the shuttle box C. is the guard binged or jointed to the
handrail at C¹.
The guard Ċ may be operated in conjunction with the starting gear of the loom
by suitable connections those shown in the drawings consisting of the short rod D
jointed to lever E which is fulcrumed at E' and is jointed to the long rod F which
connects with the starting gear of the loom. The form of lever E shown in
Figures 1 and 2 slightly varies but the principle of action is similar. When the
loom is working the guard is in the position shown in Figures 1 and 3 when it is
not working the guard takes the position shown in Figure 4. Figure 2 shows the
guard in plan partly raised.
By this arrangement of movable guard the guard is not in the worker's way like
the ordinary fixed guard while tying yarn and so forth during the stoppage of the
loom but is present to stop the shuttle from being thrown out while working and
the movement is always effected by the very act of starting or stopping the loom.
The guard is however under the control of the weaver independently of the stop
motion.
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
I claim is
In a loom a movable shuttle guard operated either by the weaver or in connection
with the starting gear substantially as and for the purpose specified.
Dated this 20th day of February 1835.
