PROVISIONAL SPECIFICATION.
Improvements in or connected with Loom Shuttle Guards.
I, TIMOTHY YATES, of 33, Richmond Street, Preston, in the County of
Lancaster, Overlooker, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements connected with loom shuttle guards of
the kind described in the Specification of my former Patent No. 14,298 of 1892 in
which the pressure of a spring or springs is employed to hold the guard rod in
position over the shuttle race but in such manner that should the said guard rod
meet or come against any obstruction as the reed is beating up it is capable of
giving way against the pressure of the said spring or springs.
In carrying out my present invention I form and mount the guard rod as before
that is to say I make it of light round bar iron or steel bent up and cranked at
each end the long intermediate part constituting the guard rod and the outer
ends forming necks which are enclosed in bearings attached to the front of the
slay cap. One or both of the necks is continued through the bearing or bearings
and bent down so as to form a crank after the style of a winch handle. I employ
one or more vertically arranged helical springs to pull upwardly at the said crank
one end of the said spring or springs being connected to that part of the crank or
bent rod which corresponds to the crank pin" and the other end being connected
to a fixed pin or stud projecting from a bracket or arm secured to the upper part
of the slay cap. The pull of the spring or springs is preferably so arranged that
the guard rod can be readily pushed back out of the way that is to say under the
lower edge of the slay cap and where it will remain whilst the loom remains
stopped-but upon the loom being re-started the shake or sudden reciprocatory
movement of the slay will cause the guard rod to be released and to assume its
normal or former position over the shuttle race.

Improvements in or connected with Loom Shuttle Guards.
1, TIMOTHY YATES, of 33, Richmond Street, Preston, in the County of
Lancaster, Overlooker, 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 improvements connected with loom shuttle guards of
the kind described in the Specification of my former Patent No. 14,298 of 1892
in which the pressure of a spring or springs is employed to hold the guard rod in
position over the shuttle race but in such manner that should the said guard rod
meet or come against any obstruction as the reed is beating up it is capable of
giving way against the pressure of the said spring or springs."

page_text: In carrying out my present invention 1 form and mount the guard rod as before
that is to say I make it of light round bar iron or steel bent up and cranked at
each end the long intermediate part constituting the guard rod and the outer ends
forming necks which are enclosed in bearings attached to the front of the slay
cap. One or both of the necks is continued through the bearing or bearings and
I employ one
bent down so as to form a crank after the style of a winch handle.
or more vertically arranged helical springs to pull upwardly at the said crank one
end of the said spring or springs being connected to that part of the crank or bent
rod which corresponds to the "crank pin" and the other end being connected to a
fixed pin or stud projecting from a bracket or arm secured to the upper part of
the slay cap.
The pull of the spring or springs is preferably so arranged that
the guard rod can be readily pushed back out of the way that is to say under the
lower edge of the slay cap and where it will remain whilst the loom remains
stopped but upon the loon being re-started the shake or sudden reciprocatory
movement of the slay will cause the guard rod to be released and to assume its
normal or former position over the shuttle race.
In the accompanying drawings,
Fig. 1 is a front view of a loom slay cap having my improved shuttle guard
applied thereto;
Fig. 2 is a cross section shewing the said shuttle guard in position over the shuttle
race; and
Fig. 3 an end view shewing the guard rod and spring in the positions which
obtain when the guard rod has been pushed under the slay cap as herein before
mentioned.
a is the slay cap b the guard rod cc the bearings carrying the said guard rod
and d a spring stretched between the fixed pin or stud e and the end of the bent
arm or ciank f. The dark circle c at Fig. 3 indicates the position of the bearing
and it will be apparent that when the crank arm f is pushed beyond the vertical
centre line of the said bearing the spring will be hard up against the face of the
slay cap a and will retain the guard rod under the lower edge of the slay cap until
released either by hand or by the re-starting of the loom and consequent shaking
movement of the slay cap.
Obviously a spring such as d may be employed at both ends of the improved
shuttle guard if thought desirable instead of only at one end as shewn in the
drawings.
When the reed space of the loom is of greater width than usual one or more
additional bearings may be introduced and the guard rod bent or cranked
accordingly (as shewn at Fig. 4).
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that wha
I claim is
The improved shuttle guard constructed arranged and operating substantially a
herein described and shewn in the drawings.
