PROVISIONAL SPECIFICATION.
Improvements in 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:-
My invention has for its object to provide a loom shuttle guard in which the
guard rod (or bar which stands over the path traversed by the shuttle) may be
moved backwardly towards the reed or readily give way against the pressure of a
spring should the said guard rod meet or come against any obstruction as the reed
is beating up this arrangement obviating the liability of injury to the fingers of the
weaver or attendant heretofore arising through jamming between fixed guard rods
and the top or cover of the loom temple.
I form the body part of my improved loom shuttle guard of light round bar iron
or steel which is bent up and cranked at each end of the long middle part which
constitutes the guard rod so as to form journals or bearings which pass through
hinge joints fastened to the front of the slay cap, these journals or bearings being
parallel with the guard rod. The bent rod after passing through the joints is
turned up at each end at right angles so as to form arms or stops which pass over
and rest upon the curved upper surface of the slay cap. One of the said arms is
pressed down upon by the free end of a flat spring (whose other end is fastened to
the top of the slay cap) the pressure of the spring being sufficient to hold the arm
down and the guard rod in position over the shuttle path but capable of readily
giving way should the guard rod receive pressure from the front in the direction of
the reed.
I provide a cam and a small operating handle or other suitable device on the
upper part of the slay cap so arranged that the arm upon which the spring presses
down as aforesaid may be raised (and consequently the guard rod moved back out
of the way) at will when desired and the said arm and spring sustained in their
uplifted position either whilst the loom is running or whilst it is stopped.

COMPLETE SPECIFICATION.
Improvements in 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' and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement :-
My invention has for its object to provide a loom shuttle guard in which the
guard rod (or bar which stands over the path traversed by the shuttle) may be
moved backwardly towards the reed or readily give way against the pressure of a
spring should the said guard rod meet or come against any obstruction as the reed
is beating up, this arrangement obviating the liability of injury to the fingers of the
weaver or attendant heretofore arising through jamming between fixed guard rods
and the top or cover of the loom temple.
I form the body part of my improved loom shuttle guard of light round bar iron
or steel which is bent up and cranked at each end of the long middle part which
constitutes the guard rod so as to form journals or bearings which pass through
Price 8dl

page_text: hinge joints fastened to the front of the slay cap, these journals or bearings being
parallel with the guard rod. The bent rod after passing through the joints is
turned up at each end at right angles so as to form arms or stops which pass over
and rest upon the curved upper surface of the slay cap. One of the said arms is
pressed down upon by the free end of a flat spring (whose other end is fastened to
the top of the slay cap) the pressure of the spring being sufficient to hold the arm
down and the guard rod in position over the shuttle path but capable of readily
giving way should the guard rod receive pressure from the front in the direction of
the reed.
I provide a cam and a small operating handle or other suitable device on the
upper part of the slay cap so arranged that the arm upon which the spring presses
down as aforesaid may be raised (and consequently the guard rod moved back out
of the way) at will when desired and the said arm and spring sustained in their
uplifted position either whilst the loom is running or whilst it is stopped.
In the accompanying drawings
Figs. 1, 2 and 3 are respectively side, plan, and end views of my improved loom
shuttle guard as above described.
a is the "body part" of the apparatus-constituting the guard rod-carried in
journals or bearings b b which may conveniently be formed of sheet metal bent over
and pressed to the required shape. These journals are fastened to the front of the
slay cap c by bolts and nuts d d. ce are the arms (being continuations of the rod a)
which in the said figs. are bent so as to pass over the upper surface of the slay cap c
and fare flat springs whose free ends press upon the arms e e. When the guard
rod a receives pressure from the front it gives way and recedes against the pressure
of the springsff towards the position indicated by broken lines at Fig. 3.
Figs. 4 and 6 illustrate a modification of my improved apparatus in which the
arn a and the spring fare arranged on the front of the slay cap c instead of on the
top of it as in the preceding figures.
In ordinary or narrow looms one spring such as f will be found sufficient as
shewn in Fig. 4 but in wider looms two springs may be required and in extra wide
looms several of such springs and in the latter case the guard rod may if desired
be made in two or more sections and mounted for instance in the manner shewn at
Figs. 5 and 7.
Fig. 8 illustrates in plan view a method whereby a single spring may be
arranged to impart the required pressure upon two adjoining sections of the guard
rod and Fig. 9 is a front view of such a spring detached.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
The improved loom shuttle guard consisting of a bent rod carried in bearings in
front of the slay cap the body part of said rod being held in position over the
shuttle path by the pressure of a spring or springs and being capable of giving way
against the pressure of said spring or springs substantially as described and shewn
in the drawings for the purpose specified.
