A Tool or Appliance for Manufacturing the
"
Mail" in Weaving.
I, JAMES STEVENSON, of 20 High Holborn, London W.C. Civil Engineer &
Patent Agent do hereby declare the nature of this invention to be as follows:-
The object of my Invention is to produce four "mails" simultaneously, perfectly
finished and separated from their cuttings. The tool is made up of metallic pieces,
preferably of iron or steel as may be found most appropriate and are represented in
the accompanying drawings separately as being laid flat on a horizontal surface..
Referring to the drawing Figure 1 is a back or under view of the turning needle
holder, which is of angular shape and bevelled to adapt under the piston of the
machine.
Figure 6 represents the turning needles B CD E. The four large oval orifices of
the turning needle holders receive four turning needles B. The four small oval
orifices receive four turning needles D. The eight small round orifices receive
eight turning needles E. and the two rectangular orifices, receive two turning
needles C.
Figure 3. is the matrix having four large oval, four small oval, eight small round
and two rectangular orifices all of which correspond exactly with the turning needles
disposed or arranged in the said turning needle holders. Two small buffers H. K.
shown in section figure 7. are strongly fitted to the matrix at their extremities, corre-
spond exactly with the two rectangular holes and form a projection throughout their
thickness at the surface of the matrix.
Figure 2. is a channel or eye perforated with holes which correspond exactly with
those of the matrix. It is of sufficient thickness to serve as channel to all the
turning needles and to guide them exactly, without any deviation throughout their
backward and forward movement.
Figure 4. is a guide of which the two long lateral pieces fixed by two transverse
pieces form a channel to lead the band.
Figure 5. is a piece forming a frame which is separated by an intermediate
027

page_text: space T. V. and having two triangular projections M. N. which correspond exactly
with the notches M. N. of the matrix figure 3. and fit in exactly when the two pieces
are superposed.
The parts are superposed in the following order:
The piece figure 5 below, then the matrix figure 3, then the guide figure 4, and at
the top the channel figure 2.
These three latter are assembled by four gudgeons which enter their respective
holes A. and which correspond exactly therewith.
The action of the apparatus is as follows:
the
The band is lead into the guide. The former hits against the buffers K. H of the
matrix. The turning needles in their descent pierce eight small round holes, 4 oval
holes and two rectangular holes. The turning needles being raised, the buffers in
entering these two latter holes allow the band to advance an equal length;
turning needles in their downward movement pierce again 12 holes and two
rectangular incisions as before and two of the large oval turning needles cut out two
"mails."
The turning needles being again raised the band now advances the length of the
rectangular incision, the latter following the band without interval.
The turning needles in descending cut out this time 4 "mails" and pierce again
12 holes and two long incisions.
From this moment each descent of the turning needles cut out 4" mails" similar
to the one represented in figure 8. and at the same time pierce twelve holes and two
preparatory incisions for the "mails" which follow afterwards.
The "mails" fall under the matrix in the larger of the two cases formed by the
intermediate space
T. V. of the piece figure 5. They are thus separated from all the
cuttings which fall into a smaller case or receptacle.
The band comes out separated or split up in three parts.

I, JAMES STEVENSON of 20 High Holborn, London, W.C. Civil Engineer and
Patent Agent, 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, reference being also had to the drawings accompanying
the Provisional Specification:
The object of my Invention is to produce four mails simultaneously, perfectly
finished and separated from their cuttings. The tool is made up of metallic pieces
preferably of iron or steel as may be found most appropriate and are represented in
the accompanying drawings separately as being laid flat on a horizontal surface.
Referring to the drawing, Figure 1 is a back or under view of the turning
needle holder, which is of. angular shape and bevelled to adapt under the piston of
the machine.
Figure 6 represents the turning needles B CD E. The four large oval orifices of
the turning needle holders receive four turning needles B. The four small oval
orifices receive four turning needles D. The eight small round orifices receive eight
turning needles E, and the two rectangular orifices receive two turning needles C.
Figure 3 is the matrix having four large oval, four small oval, eight small round
and two rectangular orifices all of which correspond exactly with the turning needles
disposed or arranged in the said turning needle holders. Two small buffers H, K,
shown in section Figure 7 are strongly fitted to the matrix at their extremities, corre-
spond exactly with the two rectangular holes and form a projection throughout their
thickness at the surface of the matrix.
Figure 2 is a chanuel or eye perforated with holes which correspond exactly with
those of the matrix. It is of sufficient thickness to serve as channel to all the turning
needles and to guide them exactly without any deviation throughout the backward
and forward movement.
Figure 4 is a guide of which the two long lateral pieces fixed by two transverse
pieces form a channel to lead the band.
Figure 5 is a piece forming a frame which is separated by an intermediate space T, V,
and having two triangular projections M, N, which correspond exactly with the
notches M, N, of the matrix Figure 3 and fit in exactly when the two pieces are
superposed. The parts are superposed in the following order :-The piece Figure 5
below, then the matrix Figure 3, then the guide Figure 4, and at the top the channel
Figure 2. These three latter are assembled by four gudgeons which enter their
respective holes A and which correspond exactly therewith.
The action of the apparatus is as follows:-The band is led into the guide, the
former hits against the buffers H, K, of the matrix. The turning needles in their
descent pierce eight small round holes, 4 oval holes and two rectangular holes. The
turning needles being raised, the buffers in entering these two latter holes allow the

page_text: band to advance an equal length; the turning needles in their downward movement
pierce again 12 holes and two rectangular incisions as before and two of the large
oval turning needles cut out two "mails." The turning needles being again raised
the band now advances the length of the rectangular incision, the latter following
the band without interval. The turning needles in descending cut out this time
4 "mails" and pierce again 12 holes and two long incisions; from this moment each
descent of the turning needles cut out 4 "mails similar to the one represented at
Figure 8, and at the same time pierce twelve holes and two preparatory incisions for
the "mails" which follow afterwards. The mails fall under the matrix in the larger
of the two cases formed by the intermediate space T, V, of the piece Figure 5, they
are thus separated from all the cuttings which fall into a smaller case or receptacle.
The band comes out separated or split up into three parts.
Any number of "mails" (6, 8, 10 for example) may be made on the same principle,
by employing metal bands of suitable width with an appropriate tool.
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:
:-
First The improved tool or appliance for the production of 4, 6, 8, 10 or more
"mails" at one operation entirely finished and separated from their cuttings, and the
arrangement of the various parts substantially as herein set forth.
Second-The arrangement of turning needles for piercing, notching, boring and
punching, mounted upon a turning needle holder substantially as herein set forth.
Third The part serving as a guide to each of the turning needles in their
movement to and fro substantially as herein set forth.
Fourth-The employment of a matrix having two buffers, and guide placed above
in order to conduct the band to be stamped in such manner that the turning needles
of rectangular shape carry away pieces of this band by making an uninterrupted
channel allowing of the band to advance each time to the length of a mail" in
order that the large oval needles stamp the "mails" of which the holes have previously
been pierced.
"
Fifth-The rectangular receptacle divided by an intermediate space forming two
compartments one of which receives the pieces cut out of the holes of the "mails
and the other the finished mails substantially as herein set forth.
