PROVISIONAL SPECIFICATION.
Improvements in Pattern Lags and Pegs used in Looms for
Weaving.
I, CHARLES HUDSON, of 10 Ash Grove, Ingrow, near Keighley, in the County
of York, Weaving Overlooker, do hereby declare the nature of this invention to
be as follows:-
It consists of an improved method of constructing pattern lags and pegs, for
operating upon, or indicating the levers in connection with the shuttle box, or
heddle operating mechanisms, of looms for weaving, the object of my invention
being to construct such pattern lags and pegs, whereby they are not only more
durable and reliable, but also lighter, and less expensive than the pattern lags and
pegs as heretofore constructed and arranged.
In order to effect my object, I take thin sheet metal lags, similar to ordinary
pattern cards, prepared with several parallel slits or pockets placed at regular
intervals, for the purpose of securing pegs thereto, such slits or pockets corresponding
to the holes usually formed in wooden lags for securing the ordinary wooden pegs.
These slits or pockets are made, preferably, by cutting the sheet metal lags at
the required intervals and then pressing out the cut parts.
The pegs I construct of strips of thin steel or like material, which I bend double,
and turn the two ends approximately at right angles, so that the said ends can be
fitted into the slits or pockets of the lags, the elasticity of the material being
sufficient to then hold the pegs securely to the lags.
The lags are linked together to form an endless chain, and are prepared for
mounting on the polygonal barrel, similarly to ordinary pattern cards, as is well
understood.
Dated this 1st day of January 1894.

COMPLETE SPECIFICATION.
Improvements in Pattern Lags and Pegs used in Looms for
Weaving.
I, CHARLES HUDSON, of 1 Haincliffe Road, (formerly of 10 Ash Grove)
Ingrow, near Keighley, in the County of York, Weaving 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:-
It consists of an improved method of constructing pattern lags and pegs for
operating upon, or indicating the levers in connection with the shuttle box, or
heddle operating mechanism of looms for weaving; the object of my invention
being to construct such pattern lags and pegs, whereby they are not only more
durable and reliable, but also lighter and less expensive than the pattern lags and
pegs as heretofore constructed and arranged.
In order to fully explain my invention, I append hereto a sheet of drawings
marked with letters of reference.
Fig. 1 of these drawings represents a plan of a pattern lag arranged and
constructed according to my invention.
Fig. 2, is a side or top view, and

page_text: Fig. 3 is an end view of the same.
Figs. 4, 5, 6, 7, and 8, are details hereinafter explained, and
Fig. 9 is a plan view of two lags showing the method of joining the lags together
to form an endless chain.
Words importing the singular number only include the plural and vice versa.
My improved lag, marked on the drawing A, is constructed of a thin piece of
sheet metal, in which are formed a number of parallel slits or pockets B, preferably
by stamping, that is by pressing the raised portion forming the pocket out of the
solid sheet. These pockets correspond with the holes in the ordinary wooden lags
or cards, and are formed for the purpose of securing to the lags the spring metal
pegs C, corresponding to the ordinary wooden pegs. The pegs C, 1 construct of
thin tempered spring steel or like material, which is bent or formed in the manner
shown in Figs 4 and 5. It will be seen that the strip of metal forming the peg is
bent double, and the two ends e turned approximately at right angles. In order
to fasten the pegs C to the lags, the ends c, are sprung into the pockets B of the
lags, when the pegs assume the shape shown by Fig. 3 of the drawings, and by
reason of the shape and material from which the pegs are made they require no
further attachment to the lags, the spring action of the pegs being sufficient to
securely hold them in the pockets.
The lags are prepared with holes D to correspond with the usual pegs on the
pattern cylinder, so that as the cylinder is revolved the endless chain of lags A is
drawn round.
The lags A are joined together to form an endless chain by means of rings or
hooks, but preferably in the manner shown by the drawings. For this purpose,
the lags A are prepared with slotted holes E, and a slot or opening at right angles
thereto running to the outside edges of the lags. Rings F are passed into the
slotted holes, and the lags joined together thereby. The intervening space between
the rings is filled by means of clips or distance pieces G, which are sprung over
the ends of the lags. The construction of these clips is shown in Figs. 6 and 7.
I construct these of thin spring steel, and form same with an indented portion g
fitting into the slotted hole E so that when the distance pieces are sprung onto the
lags the indented portions fit into the holes E, which prevents any movement of
the distance pieces end ways.
The clips or distance pieces are prevented from movement sideways by means of
a recess formed at each end of the lags.
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 :
Firstly. A pattern lag or card for use in connection with looms for weaving,
constructed of thin sheet metal, and provided with pockets for the purpose of
receiving the ends of self-fastening spring steel pegs, substantially in the manner
as shown and described.
Secondly. A peg for use in connection with the pattern mechanism of looms for
weaving, constructed of thin tempered spring steel or like material, and in the
manner shown by the drawings, in combination with a sheet metal lag prepared
with slits or pockets for the reception of the ends of the spring steel pegs, which
are thereby fastened to the lag, substantially in the manner as shown and described.
Thirdly. A pattern chain applicable to looms for weaving, constructed of sheet
metal lags prepared with pockets for receiving the ends of self-fastening spring
steel pegs, and joined together by means of rings, substantially in the manner as
shown and described.
