I, WILLIAM PHILLIPS THOMPSON, FCS., MIME, of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both
in the County of Lancaster, 118, New Street, Birmingham, in the County of
Warwick, and 322, High Holboin, in the County of Middlesex, Civil Engineer, do
hereby declare the nature of this invention to be as follows.
The present invention relates to a pattern lag. In the various pattern lags at
present in use the pins are either only seated in holes and held tast by simple
friction or they consist of tuining pin members or pin members capable of being
taken to pieces, which are held fast by rods or the like members to be fastened.
These arrangements are of such a kind that the pins or similar members intended
for the same object do not hold firmly enough or the re-setting is tedious
The present invention has for its object a pattern lag which avoids such like
drawbacks and is based upon an arrangement of spring insertion pins which can
be introduced separately in theu seats from above
After being placed in these seats or pin holes the pins remain firmly gupped.
By means of force acting against the spring, which can for example be exercised
by the hand or with the fingers or pincers, the individual parts can be again just
as easily taken out.
In the accompanying drawing:
Figure 1 shows a view of the pattern lag seen from above
Figure 2 the same in longitudinal section on the line Z-Z of Figure 1.
Figure 3 a cross section on the line Y-Y Figure 1 and
Figure 4 amilar view on the line X-X Figure 1 whilst
Figure 5 shows two views of a pin
The wooden body a of the pattein lag 18 formed in the well known suitable
manner and contains on its upper side a longitudinal recess aº
Grooves a and a³
are formed in the sides of said longitudinal recess into which are firmly inserted
the two flat rods b¹ b³ The flat rods b' and 63 have slots 60, which seive as pin
holes and as seats for the pins These flat 1ods are formed of hard material in
order that the pin seats may not wear away by frequent use as is generally the
case if metal pins are fixed in wooden seats
The pattern lag pins are springy and consist preferably of metal They are
formed of a horse-shoe shape bont out of flat metal wire, in such a manner that
both shanks spring to the outside, when they are fixed in the pin holes or seats
Small notches or bent in pieces and serving as locking notches are formed on
the shanks to engage the flat rods 6' 6 by means of which notches the pins care
secured in their pin holes 6º, as shown in Figures 2 and 3.
In order to fix the pin in position these shanks are pressed somewhat together

page_text: and introduced from above into the openings until both the notches c¹ and c³
have reached the flat 1ods b' and 6 whereupon the parts snap or lock together.
This excellent firm position of the pin in the pin holes is not only rendered pos-
sible by the notches but also because the respective openings 60 of the two flat
rods are placed one over the other and that the pins he close against the sides
of the holes
The several positions on holes of the lags may be suitably numbered

I, WILLIAM PHILLIPS THOMPSON, F.C.S, M.I ME, of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both
in the County of Lancaster, 118, New Street, Birmingham, in the County of
Warwick, and 322, High Holborn, in the County of Middlesex, Civil Engineer, de
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:-
The present invention relates to a pattern lag for Jacquard or like shaft
Dachines. In the various pattern laga at present in use the pins or pegs are either
only seated in holes and held fast by simple fiction or they consist of turning
pin members or pin members capable of being taken to pieces, which are held
last by rods or the like members to be fastened These arrangements are of such
a kind that the pins or similar members intended for the same object do not hold
firmly enough of their adjustment is too tedious
The present invention has for its object a pattern lag which avoids such like
drawbacks and is based upon an arrangement of spring insertion pins which can
be introduced separately in then seats from above.
After being placed in these seats or pin holes the pins remain fimly gupped.
By means of force acting against the spring, which can for example be exercised
by the hand or with the fingers or pincers, the individual parts can be again just
us easily taken out
In the drawings accompanying the Provisional Specification.
Figure 1 shows a view of a pattern lag seen from above.
Figure 2 the same in longitudinal section on the line Z-Z of Figure 1.
Figure 3 a cross section on the line Y-Y of Figure 1, and
Figure 4 similar view on the line X-X of Figure 1, whilst
Figure 5 shows two views of a pin
The wooden body a of the pattern lag is formed in the well known suitable
manner and contains on its upper side a longitudinal recess a° Grooves al and a³
are formed in the sides of said longitudinal recess into which are firmly inserted
the two flat rods which lie one above the other and form the seats organ
The flat rods 6 and 6 have slots 60 which serve as pin holes and as seats for the
pins These flat rods are formed of hard material in order that the pin seats may

page_text: not wear away by frequent use as is generally the case if metal pins are fixed in
wooden seats.
The pattern lag pins are springy and consist preferably of metal They are
formed of a horse-shoe shape bent out of flat metal wire, in such a manner that
both shanks spring to the outside, when they are fixed in the pin holes or seats
Small notches or bent in pieces c' and seiving as locking notches are formed on
the shanks to engage the flat 1ods bb by means of which notches the pins o are
secured in the pin holes 6º, as shown in Figures 2 and 3
In order to fix the pin in position these shanks are pressed somewhat together
and introduced from above into the openings 60 until both the notches c¹ and o
have reached the flat 1ods b¹ and whereupon the parts snap or lock together
This excellent firm position of the pin in the pin holes is not only rendered pos-
Bible by the notches cc but also because the respective openings 60 of the two flat
rods are placed one over the other and that the pins lie close against the sides
of the holes.
The several positions or holes of the lags may be suitably numbered
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed as communicated to
me by my foreign comespondents, I declare that what I claim is:-
1 A pattern lag for Jacquard or the like shaft machines, chai acterised by the
separate pins, which are capable of being inserted on set, being made in the form
of a spring auch and adapted to be introduced from above with then arched mima
into the pin holes which serve as seats, and to remain hmly clamped after then
insertion by reason of the sping action, whilst the ends of the arch or loop may
be approached by the use of force to over-come the spring pressure, as for instance
by the use of the fingers or pinceis, so that the separate pins may be withdrawn
fiom the respective holes substantially as herein before set forth
2 A pattern lag for Jacquard or like shaft machines, characterised by the
separate pins being made in the form of a sping horse-shoe shaped loop of flat
metallic wie, adapted, after pressure agamst the spring action, to be inscited with
then loop ends in the pin holes which serve as seats and to be removed from said
seats, and by the actual seats being formed of metal and the aims provided with
snap spings (c) substantially as herembefore described
3 A pattern lag for Jacquard or the like shaft machines, in which the separate
pins form sping loops (c) adapted, after pressure against the sping action, to be
inserted with the ends of the loops in the pin holes (69) which serve as seats and
capable of being withdrawn from said seats, characterised by the pin seats being
formed of two flat metallic bars provided with rectangular holes () and inserted
in the longitudinal recess of the wooden pattern lags and let into grooves in the
sides of the recess, said holes in the two flat bais being an equal distance apart
and lying one above the other, substantially as hetembefore described
