Year: 1868

page_text: LETTERS PATENT to Edmund Leach, of Rochdale, in the County of
Lancaster, for the Invention of "IMPROVEMENTS IN TRAVELLING LATTICES
USED FOR CONVEYING FIBROUS MATERIALS INTO OR OUT OF MACHINES.'
Sealed the 9th April 1869, and dated the 14th October 1868.
PROVISIONAL SPECIFICATION left by the said Edmund Leach at the
Office of the Commissioners of Patents, with his Petition, on the
14th October 1868.
I, EDMUND LEACH, of Rochdale, in the County of Lancaster, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
TRAVELLING LATTICES USED FOR CONVEYING FIBROUS MATERIALS INTO OR OUT OF
MACHINES," to be as follows:-
This Invention consists in making the ends of the metal ribs or bars,
of which the lattice is composed, of improved shapes, and employing
connecting links for enabling the ribs to be readily jointed together in
an efficient and economical manner..

page_text: In one arrangement both ends of each rib are formed similar to the
link of a square chain, and the links are jointed together by connecting
links formed of two pieces screwed or rivetted together, or by links
which when placed in one position can be put on and taken off, but
when placed in another position are properly jointed to the links of the
chain without any screws or rivets.
In another arrangement there are two pins at the end of each rib,
and the ribs are connected together by ordinary connecting links held
in their places by fastened cross pieces.
The manner in which this Invention is to be performed will be under-
stood by referring to the figures and letters on the accompanying outline
Drawing, in which Fig. 1 is a plan, and Fig. 2 a side view of one end
of the ribs drawn about full size; Fig. 3, a plan of one end of two of the
ribs and one arrangement of connecting links; Fig. 4, a vertical section
at the line A, B, Fig. 3; and Fig. 5, a plan of several ribs and connecting
links drawn to a reduced scale.
Fig. 6 is a side view of some of the ribs held together by another
arrangement of connecting links, the end marked C shewing the position
of a rib and link when the latter is to be put on or taken off.
Fig. 7 is a plan, and Fig. 8 an end view of another arrangement for
jointing the ribs together, and Fig. 9 is a plan of part of a chain,
to which ribs of wood, gutta percha, or other material can be fastened.
In Figs. 1, 2, 3, 5, and 6, a represents the ribs in part or entire, each
end of cach rib being formed with two pins and a cross piece c, and
these pins are jointed together to the pins of the next ribs by connecting
links d formed of two parts screwed together by the screws e, and
between the links there are spaces f, into which the teeth of the driving,
chain wheels enter as the wheels revolve, and give travelling motion
to the lattice. The ribs may be of a curved shape, as shewn in the
Figures, or they may be semicircular or flat, and when desired one or
more slots g, Fig. 5, may be formed in them when employed in washing
or other machines in which water or liquors are used.
In Fig. 6 the connecting links have slots: h, which can pass over the
cross piece c, as shewn at C, and then the links can be turned as at i
and joint the ribs together.
In Figs. 7 and 8 the ribs a have two pins b, on which are placed the
connecting links k, and over the pins of each rib is placed a cross

page_text: picce l, which is. held in position by nuts or by rivetting the ends of the
pins, and the projections marc for preventing the nuts from touching
the framework.
In Fig. 9 the chain and connecting links are similar to those before
described, but to the pins bare cast short ends n, to which ribs of wood
gutta percha, or other material can be screwed, rivetted, or otherwise
fastened..
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edmund Leach in the Great Seal Patent Office
on the 14th April 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDMUND
LEACH, of Rochdale, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of October, in the year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Edmund Leach, Her special license that
I, the said Edmund Leach, my executors, administrators, and assigns, or
such others as I, the said Edmund Leach, my executors, administrators;
and assigns, should at any time agree with, and no others, from time
to time and at all times thereafter during the term therein expressed;
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands, and
Isle of Man, an Invention for "IMPROVEMENTS IN TRAVELLING LATTICES USED
FOR CONVEYING FIBROUS MATERIALS INTO OR OUT OF MACHINES," upon the
condition (amongst others) that I, the said Edmund Leach, my executors
or administrators, by an instrument in writing under my, or their, or
one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was to
be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said Edmund Leach, do hereby declare
the nature of my said Invention and in what mannan the came in de h

page_text: performed, to bo particularly described and ascertained in and by tlie
following statement (that is to say) :-
This Invention consists in making the ends of the metal ribs or bars;
of which the lattice is composed, of improved shapes, and employing
connecting links for enabling the ribs to be readily jointed together in
an efficient and economical manner.
In one arrangement both ends of each rib is formed similar to the
link of a square chain, and the links are jointed together by connecting
links formed of two pieces screwed or rivetted together, or by links
which when placed in one position can be put on and taken off, but
when placed in another position are properly jointed to the links of the
chain without any screws or rivets.
In another arrangement there are two pins at the end of each rib,
and the ribs are connected together by ordinary connecting links held in
their places by fastened cross pieces or retaining bars.
The manner in which this Invention is to be performed will be clearly
understood by the following particular description thereof, reference
being bad to the Figures on the accompanying Sheet of Drawings and
to the letters of reference marked thereon.
Fig. 1 is a plan, and Fig. 2 a side view of one end of the ribs or bars
of which the lattice is composed drawn about full size; Fig. 3, a plan
of one end of four of the ribs and one arrangement of connecting links;
Fig. 4, a vertical section at the line A, B; Fig. 3; and Fig. 5, a plan of
several ribs and connecting links drawn to a reduced scale.
Fig. O is a sido view of some of the ribs held together by another
arrangement of connecting links, the end marked D shewing the position
of a rib and link when the latter is to be put on or taken. off; Fig. 7,
a plan of the same.
Fig. 8 is a plan, and Fig. 9 an end view of another arrangement for
jointing the ribs together.
Fig. 10 is a plan of part of a chain, to which ribs or bars of wood,
gutta percha, or other material can be fastened, and Figs. 11 and 12 are
end views of modified forms of ribs.
a, Figs. 1, 2, 3, 6, 7, and 8, represents one end of the ribs, and a,
Fig. 5, the ribs their entire length. Each rib is formed with two pins b
and a cross pièce ar retaining bar c, and these pins are jointed together
to the pins of the next ribs by connecting links d formed of two parts

page_text: screwed together by the
screws e, and between the links there are
spaces f, into which the teeth of the driving chain wheels enter as the
wheels revolve and give travelling motion to the lattice. The ribs may
be of a curved shape, as shewn in the Figures, or they may be semi-
circular or flat, and when desired one or more slots g, Fig. 5, may be
formed in them when employed in washing or other machines in which
water or liquors are used.
In Figs. 6 and 7 the connecting links have slots / which can pass
over the cross pieces or retaining bars c, as shewn at D, and then the
links can be turned as at i and joint the ribs together.
In Figs. S and 9 the ribs a have two pins b, on which are placed the
connecting links k, and over the pins of each rib is placed a cross piece
or retaining bar 1, which is held in position by nuts or by rivetting the
ends of the pins, and the projections m are for preventing the nuts from
touching the framework.
In Fig. 10 the chain and connecting links are similar to those before
described, but to the pins bare cast short ends n, to which ribs of wood,
gutta percha, or other material can be screwed, rivetted, or otherwise
fastened, and in all cases when it is desired to have no spaces between
the ribs I form them as shewn in the end views, Figs. 11 and 12.
Having now described the nature and particulars of my said Inven-
tion, and the manner in which the same is to be performed, I desire it
to be understood that I claim in travelling lattices the cross pieces or
retaining bars cast to the pins at each end of the ribs for preventing
the pins from widening from each other; the connecting links d in two
parts fastened together by screws or rivets, and the slotted connecting
links i, and also the retaining bars with their projecting pieces m, as
all such improvements are herein described and illustrated in the
accompanying Sheet of Drawings.
In witness whereof, I, the said Edmund Leach, have hereunto
set my hand and seal, this Thirteenth day of April, in the year
of our Lord One thousand eight hundred and sixty-nine.
EDMUND LEACH. (L.S.)
