PROVISIONAL SPECIFICATION,
Machines for Pegging Loom Pattern Lags.
WILLIAM CARE 19 Peel Street Barnsley, Mill Manager JAMES TAYLOR,
43 Hope Street Barnsley, Mechanic do hereby declare the nature of this invention
to be as follows:-
The invention comprises machines to substitute what is now done by hand,
namely, what is known as pegging weaving lattices or lags, used on single and
double lift open shed shaft machines, or as sometimes termed dobbies.
The machines can be constructed to suit any kind of lattices or lags by simply
varying the number of pipes and their respective distances from each other.
The description of machine is as follows. The pegs are fed into small brass
pipes, the top of these pipes being fitted into a wooden head the holes on the upper
surface of which are well countersunk so that they will easily drop in, and hold
when full, 20 in each pipe, but can be made any length as required.
The pegs are held up by means of a spring connected to which is a wire, passing
in a horizontal position to a lever inside a box, at front of machine; to the
opposite part of this lever is connected another wire, in a vertical position, passing
through the top of box, and having a knob at the top or end of wire to be pressed
upon by the fingers, so that when a peg is required out of any particular pipe, the
corresponding wire may be pressed down and releasing a peg, it drops upon a sliding
plate, and when the whole of pegs required have been released, say 10, 20, 30, or
whatever the case may be, the sliding plate is withdrawn, thus allowing all the pegs
to drop through directly upon the corresponding holes in the lattice or lag, then
the sliding plate is allowed to spring back into its original position, this time being
over the pegs now resting upon the lattice or lag, then by means of cylinder con-
taining eight grooves into which they (the lattices or lags) fit, the whole is raised
by eccentric canis, and the end of pegs coming into contact with the under side of
sliding plate, are forced into their respective holes at one time, thus projecting
from the lattice or lag exactly one length.
The machines are also fitted with board upon which to place the plan for pegging,
and is constructed so as to hold any size of paper, from its owit dimensions down-
wards, without pins, the paper being held in a vertical position by means of
adjustable spring rods, and has a sliding index plate, capable of being adjusted to
any part of plan, thus enabling the operator to refer more readily to the part he or
she may be engaged upon, and ensuring accuracy in the work.

Machines for Pegging Loom Pattern Lags.
WILLIAM CARE 19 Peel Street Barnsley Mill Manager JAMES TAYLOR
43 Hope Street Barnsley Mechanic 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 :-
The invention is a machine for pegging loom pattern lags, used on single and
double lift open shed shaft machines, or as sometimes termed dobbies; the aforesaid
process being accomplished in the following manner.-The pegs used for the lags
are placed in the box A, Sheet No. 3, and are taken from it to fill the pipes B,
^

page_text: which are fitted into the wooden head C, the pegs being inserted at D. The pegging
plan or design is placed upon the board E, being held by the rods F, F, Sheet No. 2,
these rods may be placed nearer together or further apart by sliding them upon
the shaft G, Sheet No. 2, according to the size of the plan or design. The pegs in
the pipes B, are held up by the springs H Sheet No. 1, the pipes having a slot or
parting the full length to enable the person using the machines, to see when they
are empty. The grooves B' are for the end of the springs H to catch or hold the
pegs, to these springs are connected the wires I, passing into the box J, and con-
nected to the levers K; to the opposite point of these levers is connected other
wires L, which pass out of the box J, having the knobs M on the top or end;
when a peg is required out of any particular pipe, the knob on the wire connected
to the spring on that pipe is pressed down, thus drawing the spring H away from
the groove in the pipe and allowing the peg to drop upon the sliding plate N; when
the whole of the pegs required have thus been released and are resting upon the
plate N, it (the plate) is then withdrawn by pulling the knob O, the pegs then drop
through upon the lag exactly on the holes into which they are to be pressed, the
lag fitting in the groove in the top part of the cylinder P; the sliding plate N is
then put into its original position this time being over the pegs, the lever Q is then
pulled down and by means of the eccentric cams R, on the same shaft, working on
the rollers S, the cylinder P is raised and the upper end of the pegs coming into
contact with the underside of the sliding plate N, are pressed into their respective
holes at one time and project from the lags exactly one length.
The lever is then returned into its former position against the stop stud T.
The cylinder P is kept close to the cams R by the spiral springs U and V so as to
ensure it being lowered at the same time.
The cylinder P is then turned by the lever W to the next groove containing the
next lag to be pegged, the end of the rod X holding the cylinder in its proper
position; the division plate Y (Sheets No. 2 & 4) with the same number of studs
as there are grooves in the cylinder acts as a means of adjustment and by the
catch and the lever W as a means of turning the cylinder when the operation of
pegging is to be repented; the handle wheel A' is for the purpose of turning the
cylinder back.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is,
That it comprises a method whereby machines in which pipes are fixed, according
to the number and respective distances of the holes in the lags to be pegged, and
used for the reception of the pegs, and that the pegs at the will of the operator
and according to the pegging plan or design, can be released over any hole in the
lag to be pegged, and that when released are all upon the top of a sliding plate,
the withdrawal of which, allows them to drop upon the holes into which they are
intended to be pressed; the sliding plate is then placed in its previous position
thus acting as a face against which, when a cylinder (in the grooves of which the
lags fit) is raised by means of a lever and eccentric cams, press in the pegs all at
one time and project out of the lag all one length.
