Improvements in Pegs Used in Connection with the Lags or Lattices
of Shedding Motions of Looms for Weaving.
I, WILLIAM THOMPSON of Sutton near Crosshills (via Keighley) in the County of
York, Joiner and Cabinet Maker do hereby declare the nature of this invention to be
as follows that is to say :-
used
It relates to improvements in the formation or construction of pegs
in connection with the lags or lattices of shedding motions of looms for weaving;
whereby said pegs are more securely held in position or connection with said lags by
which means their efficiency is greatly enhanced as will be well understood by users
of such parts and machinery.
As is well known these pegs are inserted or driven into openings or holes made in
the lattices or lags, for the purpose of indicating upon certain parts in the machine as
may be desired; said pegs being detachable so that their positions may be changed as
is from time to time required.
Now the object of my invention is to so construct these pegs that they may be
inserted in the same way and as readily as the common pegs at present in use, but
that they shall have the advantage above described.
This I attain by constructing them of metal said metal being preferably firstly
formed in suitably shaped strips, as of partly flattened round-wire, said strips being
of appropriate lengths so that when bent or folded double, they will be of sufficient
length to form the pegs.
The folding of said strip as above described forms a kind of bifurcated peg, the
prongs of which, are left a suitable distance apart so that when they (said prongs)
are pressed together by being inserted into the opening or hole in the lag, their
tendency, caused by the elasticity or springiness of the metal, to regain or maintain
their usual distance apart, keeps the peg in conection with its lag by the pressure of
said prongs upon the walls or sides of the openings in said lags.

page_text: If desired at a suitable distance from the outer ends of the prongs above described
a projection or shoulder, as by the strips of metal forming said prongs being bent or
knuckled, may be formed so that the distance that the pegs are driven into the lags
may be more easily and uniformly regulated.
Again, the part of the peg that does not enter the lag, but which projects therefrom
may be left sufficiently large, and bent somewhat of a square-loop shape, in order to
cover the spaces of several pegs which it might substitute provided their positions in
the lag were adjoining each other.

1, WILLIAM THOMPSON of Sutton near Crosshills (via Keighley) in the County of
York, Joiner and Cabinet Maker, 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 that is to say :-
It relates to improvements in the formation or construction of pegs
used
in connection with the lags or lattices of shedding motions of looms for weaving
whereby said pegs are more securely held in position or connection with said lags by
which means their efficiency is greatly enhanced as will be well understood by users
of such parts and machinery.
In the accompanying drawings figs. 1, 2, 3, 4 and 5 are side views shewing five
different forms of pegs constructed according to this invention, Figs. 6, 8 and 7,
9 being sectional side and top views respectively of lattices with my varied kinds of
pegs applied.
As is well known these pegs a are inserted or driven into openings or holes made
in the lattices or lags, for the purpose of indicating upon certain parts in the machine
as may be desired, said pegs a being detachable so that their positions may be
changed as is from time to time found necessary or as may be required.
Now the object of my invention is to so construct these pegs that they may be inserted
in the same way and as readily as the common pegs at present in use, but that they
shall have the advantage above described.
This is attained according to this invention by constructing the peg a of metal, said
metal being preferably as a commencement of the form shewn by the perspective
drawing fig. 1a which shews a strip of partly flattened round wire. This strip of wire
is of a suitable length so that when bent or folded double it will be of sufficient length
to form the peg a as shewn by fig. 1.
The peg a formed as described is bifurcated and its prongs c d are left a suitable
distance apart (see fig. 1), so that when they are pressed by being inserted into the
opening or hole in the lag 6 (see fig. 6) their tendency, caused by the elasticity or
springiness of the metal, to regain or maintain their usual distance apart, keeps the
peg a in connection with its lag 6 by the pressure of said prongs c d upon the
walls or sides of the openings in said lag b.
If desired at a suitable distance from the outer ends of the prongs c d above described
a projection or shoulder e, fig. 2, may be formed by which means the distance that the
pegs a are driven into the lags b may be more easily and uniformly regulated. Or
the upper, or that, part of the peg a which does not enter the opening in the lag b
may be so formed as is shewn by fig. 3, that the shoulder e is made thereon as will
be seen.
Again the upper, or that, part of the peg a which does not enter the opening in the
lag may be bent somewhat of a square-loop shape as shewn by fig. 4 in order to cover

page_text: the spaces of several pegs which it might substitute provided their positions in the
lag were adjoining each other as shewn by figs. 6 and 7.
In order that the property of the springiness or elasticity of metal may be utilized
in the construction of pegs as and for the purpose above described, pieces of metal
may be arranged and folded so that when the peg is formed it might have more than
two prongs c a as by the folding of a piece of metal, formed as shewn by fig. 10, so
that its arms f f f f³ may be brought together, in this manner effecting the desired
object.

Or again the object desired may be attained by the peg al being of tubular form and
its prongs c¹ d¹ formed as shewn by fig. 5. And when these are made use of, the
object attained by the peg shewn by fig. 4 may be attained by a piece of wire being
bent so that its outer ends will enter the openings in said pegs a¹ as shewn by
figs. 8, 9.
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 what I claim is :
1. A peg constructed of metal of the form described, having its prongs arranged to
be or to tend to be always at a suitable distance apart from each other substantially as
and for the purposes specified.
2. A metal peg a having prongs c d and a shouldered part e formed thereon the
same being used in connection with the lags or lattices & substantially as and for the
purpose specified.
3. A peg a formed with its upper part somewhat of a square-loop-shape as shewn
by fig. 4, and having prongs c d the same being used as and for the purpose specified.
4. The peg a formed of tubular shape and having one of its extreme ends
terminating in the prongs c¹ d' as shewn and for the purpose substantially as set
forth.
5. A peg to be used in connection with the lags or lattices of looms for weaving,
said peg being formed to have four yielding prongs as shewn at f f f² ƒ³, fig. 10,
substantially as and for the purpose herein described and set forth.
6. A peg to be used in connection with the lags or lattices of looms for weaving, the
same being formed to have two or more prongs which are arranged to be or to tend
always to be at a suitable distance apart from each other substantially as and for the
purposes specified.
