IMPROVEMENTS IN (MAIL) HEALD MACHINES
Year: 1884

page_text: JEREMIAH ROBERTSHAW Heald Maker Thornton near Bradford Yorkshire do
hereby declare the nature of my invention for IMPROVEMENTS IN (MAIL) HEALD
MACHINES, to be as follows:-
My Invention is a motion fit on to a "stud," This stud forms a fulcrum. The
stud is screwed fast to the top of the machine.
From the part fitting the stud are two arms (or levers) one arm goes down to
the "tappet shaft" to be worked by a tappet, and the other arm is made to hang
just over the mail-wire, at about two inches from the "Bridge." (Where the mails
come out) The end that hangs over the mail-wire has two needles (or small steel-
wire points will do) screwed to it, one goes on each side of the mail-wire.
The other end that goes down to Tappet shaft is worked by a tappet.
This tappet rises the two needles off the mail-wire just sufficient time to allow
the mail-carrier to pass with a mail and then it is lowered on to the mail-wire
again.
.
:
It gives the following results. It reduces the friction on the yarn. Caused
by the yarn passing through the mail (after the mail has been first delivered) at
too great an angle.
By working as follows. When a mail has been delivered from under the
"bridge" (called the first delivery) the two needles fall down before the mail and
prevent it being pulled as far from the bridge as it could be. Thus the yarn goes
through the mail straighter. (At a less anglo).
Also. It keeps The Mail Ready. With the two needles holding back the mail,
the mail remains still, and is therefore ready to be taken forward by the mail
carrier when required. Without my motion the friction with the yarn passing
through the mail is so great and suddenly caused that the nail is pulled violently
forward, (after being delivered from under the bridge) that it chucks back again
behind the mail-carrier. This is particularly so in making "polished" Cotton
Healds.
And also: It keeps the mail-wire in its position. With the two needles falling
one on each side of the mail-wire it thus keeps it in its position.

page_text: Jeremian Robertsnaw, Heald Maker, Thornton near Bradford, Yorkshire do
hereby declare the nature of my invention for IMPROVEMENTS IN (Mail) Heald
MACHINES and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
My Invention is a motion fit-on to a "stud," this stud forms a fulcrum, This
stud is screwed fast to the top of the machine.
From the part fitting the stud are two arms (or levers) one arm goes down to
the "Tappet shaft" to be worked by a tappet, The other arm is made to hang just
over the mail-wire at about two inches from the "Bridge," (Where the mails come
out) The arm that hangs over the mail-wire has two needles (or small steel wire
points will do) screwed to it, one goes on each side of the mail-wire. A plain blade
to fall on to the mail-wire instead of the above two needles will answer the first
two features of novelty I claim for my Invention, If the mails used are large ones,'
but if the mails are little ones this plain blade lets the mail frequently slip past.
The two needles are always safe to work right.
A light spring may be put on at any convenient place to steady the motion
when it is lowered by the tappet.

To produce the First feature of novelty I claim for my Invention: vix: "It
reduces the Friction on the yarn."
"
The motion is worked as follows, We must suppose the motion to be lifted off
the mail-wire, and a. mail about to come out from under the bridge, Then the
motion is lowered so that one needle falls on each side of the mail-wire, Then the
mail comes out against these needles and remain there till the "Carrier comes for
it. Thus, by not allowing the mail to be pulled out as far as it could be without
my motion, the yarn passes through the mail at a less angle, and therefore causes
less friction. The friction may be regulated by bending the arm nearer or further
from the bridge. Thus the workman can regulate the friction at will.
In making Healds without my notion with somo kinds of yarn the friction is so
great that the yarn is partly "cut" at the mails.
When the carrier comes for the mail the motion is lifted up from before the
mail (by the Tappet working at the other arm) then the carrier can take the mail
.forward.
As soon as the carrier has gone with the mail, the motion is lowered to the mail-
wire, so that the points fall one on each side of the mail-wire as before.
The second Feature of novelty I claim, vix; "It keeps the mail ready" Is the
result of the mail not being allowed to be pulled out as far as it could be without
my motion. There is therefore no sudden friction caused.
This sudden friction is extremely troublesome in making polished Cotton Healds
(without my motion) as it chucks the mail very frequently behind the carrier.
Thus the mail is always ready for the carrier to take it.
The Third feature of Novelty I claim for my Invention, vix; "It keeps the mail-
wire in its position," Is the result of the two needles going one on cach side of
the mail-wire, In which position they remain the greater part of a revolution of
the machine.
The (Mail) Heald Machine is not a Patent.

page_text: Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
The apparatus for holding the mail & mail-wire in position as hereinbefore
described.
