Improvements of Shuttle Guards of Looms for Weaving.
1, WILLIAM SUTCLIFFE, of Waterloo Shed, Burnley, in the County of
Lancaster, Cotton Manufacturer, do hereby declare the nature of this invention to
be as follows:-
Its objects are,
1st. To obviate the possibility of injury to the weaver, and damage to the warp
in the loom, by a shuttle flying out;
2nd. To minimise the cost of shuttle-guards by dispensing with the more or
less complicated and expensive mechanism or apparatus, which have hitherto been
used, such as levers, shafts, cams, wheels, pauls, springs, tappets, weights, &c. &c.
and
3rd. To encourage the adoption of a shuttle-guard by manufacturers, by
reason of its simplicity and cheapness, and to secure the approval of tacklers,
overlookers, and weavers to such appliance, also ou account of simplicity; freedom
from extra labour or attention, and non-interference with the work of the latter.
In order to successfully accomplish these desirable objects, I securely attach,
(by means of screws, or the like), a strip of wood, or other suitable material, to the
underside or front of the slay-cap or hand-rail, either solid or perforated or slotted
to lighten the weight, or allow light to pass through on to the threads in such a
manner and position, as to project sufficiently beyond the front thereof, and pro-
jecting over the path or race of the shuttle as to form an obstruction thereto, and
resist any possibility of its escaping or deviating in an upward direction from its
usual course.
This strip or fillet does not interfere in any way with the proper functions or
working of the shuttle, excepting when it has a tendency to depart from or
fly out of its regular course, in which case, it presents an impassable and
irresistible barrier or obstruction to the shuttle, and prevents its flying upwards.
The strip may be the full length of the hand rail, (between the shuttle-boxes),
or nearly so.
Instead of using one strip as above described, the "guard" may be formed, or
consist of two pieces, or members, hinged together, so that the projecting piece may
be turned up, if desired, and stand flat against the front or near side of the hand-
rail while the loom is stopped or allowed to fall into its normal position by the
ordinary working of the loom, or when the loom is started.
The other portion or part of this double-hinged strip or strips is securely
fastened to the underside of the hand-rail in the manner previously described.
In order to hold the projecting strip or "guard," proper, securely or rigidly in
position, when in its resistive or horizontal situation, I employ another strip or
strips, hinged in two parts, the top part being fixed vertically to the front or
near side of the hand-rail, the other hanging down parallel to the rail, and its
bottom edge or side is close, or nearly so, to the "guard," which is thus prevented
from rising.
If, at any time it may be necessary to lift up, or raise the "guard," it can be
done readily, as obviously indicated, and the vertical hinged strip may be employed
to hold it in that position.
If preferred, the vertical strip may be in one part and held as desired, by means
of slides or slots, & screws, or pegs, so as to be readily raised and lowered, as

page_text: already mentioned, and either, or both of these strips,-horizontal and vertical,-
may be held in the position wished for, by hooks and eyes; thunib-screws,
turn-buttons, or other equivalent.

COMPLETE SPECIFICATION.
Improvements of Shuttle Guards of Looms for Weaving.
I, WILLIAM SUTCLIFFE of Waterloo Shed Burnley, in the County of
Lancaster, Cotton Manufacturer 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 :-
In constructing a shuttle guard according to my invention I secure a slotted or
perforated plate to the slay cap or hand rail of a loom. This slotted plate is fixed
horizontally and projects laterally and effectually prevents the shuttle from rising
or flying out of its course by which it may injure the weaver the slots or perforations
permitting the weaver to inspect the work.
Such being the nature and object of my invention I will now proceed to describe
the same more fully and for that purpose make reference to the accompanying
sheet of drawings.
Fig. 1 shews my invention wherein A is the slay cap or hand rail, B, the slay
board and C the reed arranged in the ordinary manner.
My invention consists in connecting to the hand rail A a slotted or perforated
plate D made secure to the said hand rail by screws E. It will be seen that the
position of the said slotted plate D will prevent the shuttle from flying in an
upward direction, whilst the openings or slots F in the said plate permit the
weaver to see the warp and to find broken ends. The slotted plate is made
about the length of the reed, and it may be about one and a half to two inches
wide.
Fig. 2 is plan view of said slotted plate.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The combination with the slay cap or hand rail of a loom of a slotted or
perforated plate for purposes described.
