PROVISIONAL SPECIFICATION.
An Improved Shuttle Guard for Preventing Shuttles Flying Out of
the Loom.
WILLIAM COTTRILL Manufacturer Britannia Mills, Pendleton, Manchester
WILLIAM BROWN Mechanic 199 Rochdale Road Bury Lancashire do hereby
declare the nature of this invention to be as follows:-
This invention consists of a horizontal rod or flat bar or half round bar of iron
which fits into a bracket at each end of the hand top of the loom, both brackets
have half circle slots into which the rod locks itself by means of one or two small
spiral springs.
Should the weaver leave the rod or bar turned up it will fall itself into position
& lock immeadiatly the loom is set into motion thereby automaticly preventing the
possibility of accidents from the flying of shuttles.

COMPLETE SPECIFICATION.
An Improved Shuttle Guard for Preventing Shuttles Flying Out of
the Loom.
WILLIAM COTTRILL, Manufacturer Britannia Mills Pendleton, Manchester also
WILLIAM BROWN Mechanic 199 Rochdale Road Bury, Lancashire 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 horizontal iron rod, or flat bar, or half round bar
which is fitted to the slay top or hand rail of the loom by means of two small
brackets. The bar or rod is bent or cranked at each end & its extremities are
inserted into the brackets. One of the brackets as shewn is furnished with one
or more springs & the end of the rod or bar entering therein is fitted with one or
more washers, against which the spring presses. The two brackets each have a
groove or slot cast in the sides of a size to receive a sufficient portion of the
diameter of the bar to hold it firmly therein against any effort a flying shuttle
could possibly make to raise it when attempting to leave the "shed" viz. its proper
working position in the looni. Figure 1. affixed hereto, shows the guard out of the
working position & in the one in which the weaver would place it when wanting to
draw in any broken threads. In this position, the ends of the guard are out of
the slots of the bracket, and against the polished sides. Immediately the loom is
started, the movement of the stay causes the rod or bar to slide or drop from the
above position into that shown on Figure 2. in which position it gives the security
claimed for this invention. It is thus perfectly automatic, needing no attention
from the weaver to give it efficiency.
On the stoppage of the loom for drawing in warp threads, the weaver, in order
to remove the guard has only to slide it laterally with a gentle pressure on the
spring side, when the spring yields, and the guard is lifted into the position shown
in Figure 1.
"
The brackets are slotted or grooved at the back vertically in order that they
may be lowered or raised to render them adjustable to any size of "shed that
the character of the work in the loom may require.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1st. That the flying of the shuttle is effectually prevented by the rod or bar
referred to.
2nd. That the guard by the lateral movement referred to, can be turned up out
of the weavers way, so that the warp threads can be easily pieced up when
required.
3rd. That it is not necessary that the weaver should replace the guard in its
working position as immediately the loom is re-started the guard fall automatically
into the slots of the brackets, & is firmly locked in such a position as to effectually
resist any flying of the shuttle out of the loom.
4th. That the back of the brackets being slotted or grooved vertically, the
guard can be lowered or raised, so as to suit the various classes of work which
the loom may be required to weave.
