Improvements in Leasing Mechanism for Warp Dressers.
We, JOSEPH MICHAEL SIMONEAU, of Maple Street, Ware, Massachusetts, Beaming
Operative, and EDWARD PARSONS MORSE, of Maple Street, in Ware, Massachusetts,
Farmer, both in the United States of America 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 :—
This invention relates to improved devices or mechanism used in conjunction with
a warp-dressing machine, or slasher, for securing a lease or decussative arrangement
of the warp-threads or yarns before the same pass through the dressing rolls, or
slasher, so that by the insertion of proper lease-retaining cords or rods which may
pass through the dresser or slasher with the yarn, when the leased section of the
warp yarns has come near to the warp-beam it may be cut leaving the yarn on two
equal separated portions, the yarns of the one portion alternating and still retaining
their X-like relations, so that when the said yarns are taken on the warp-beam to
the loom they may be, due to their leased condition, readily run in through the
harnesses by the "running-in-hand."
The object of this invention is to provide a device or mechanism which has
advantages as follows:-firstly, it is of simple construction and of easy operation ;
secondly, it possesses a capacity for manipulating and controlling a number of yarns
largely in excess of what we have hitherto understood to be customary and possible
in leasing devices; and thirdly, the mechanism is so equipped in relation to the set
of section-rolls in conjunction with which it operates, and with the slasher or dresser,
that it may be readily removed, with said section-rolls, from its proximity to the slasher
or dresser whereby a new set of section-rolls and a similar leasing device therefor may
be substituted, so that new work may be immediately brought to the slasher,
necessitating no delay or loss of time by the latter. And the invention consists in
the construction and combination of parts, all substantially as will hereinafter more
fully appear and be set forth in the claims.
In the accompanying drawings,
Figure 1 is a side elevation and partial vertical section of a set of section-rolls, the
lease-forming device, and a part of the dresser or slasher.
Figure 2 is a plan view of a portion of the removable lease-forming devices.
Figure 3 is a vertical cross-section on line 2-2, Figure 1.
Figure 4 is a vertical cross-section on the line 3-3, Figure 1.
Figure 5 is a detail view in illustration of an improved construction of reed which
is advantageously adapted for use in this leasing mechanism.
Figure 6 is a view in the nature of a diagram indicating an enlarged plan, or
horizontal cross-section of the reed-frames, showing the relations of the open spaces
between certain of the reed-rods and yarn-engaging abutments between other of the
reed-rods the one with the other, and the relations of the yarns with each other and
with said open reed spaces and with said spaces having yarn-engaging abutments,
shoulders, or blocks.
Figure 7 is a vertical sectional view along the run of the warp yarns through the
reeds, showing certain of said reeds as in a position occupied thereby in one part of
their lease-forming movements.
Figure 8 is a similar view to Figure 7, showing another pair of the reeds as in
the position occupied thereby in another part of the lease-forming operation.
Figures 9 and 10 show the manipulations of the lease-forming devices when the
same comprise but two reed frames."
In the drawings, A, A, represents a set of "section" or yarn-supply rolls mounted
in suitable bearings of a removable frame B, said frame being supported upon or in

page_text: proximity to a main frame D, which is also available for the reeds 1, 2, 3 and 4, said
frame D, being in proximity to, or an extension of the frame of the dresser or slasher C,
which may be of any suitable construction and operated upon any approved principle.
a, o, are guide rolls for the yarn, one a, between the section-rolls and the reeds, and
the other, o, between the reeds and the slasher. The sizing apparatus of the slasher
may be located between the said roll, o, and the large drum partly shown at the
extreme left of Figure 1.
which
All the reeds E, particular ones of which are designated by the numerals 1, 2, 3
and 4, as to their positions are mounted in a supplemental or "reed" frame F,
fits into openings of, and is supported and steadied by the common or extension
frame D. Said reed-frame comprises a supporting bottom, b, and suitable side and
end beams or walls, d, in the sides of which are vertical guide ways, f, for the
reeds, 1, 2, 3 and 4.
In relation to the foot-rail of each reed is provided an elevating device here shown
as consisting of vertical "push-up" rods, g, which are engaged by levers, h, respectively
provided therefor which levers are suitably fulcrumed on, and extended laterally
outside of, the extension frame D, for being readily swung-the reed swung
up by the action of the lever falls to the bottom of the reed-frame F, by its own
gravity.
Each reed consists of a rectangular frame having between the upper and lower
bars or rails thereof the series of vertical reed-rods, 10, with spaces, 12, between them,
said spaces being usually intended to freely admit of the side-by-side disposition of
at least three, and often more, threads or yarns, and the alternate spaces between the
reed-rods are intermediately of their vertical extent divided by a suitable filling-in
block, cross-pin, or other suitable form of yarn-engaging abutment or shoulder 13,
the essential, under whatever specific construction employed, being a reed having
suitable alternating yarn-engaging abutments in given horizontal lines, substantially
as shown, and relatively intermediate open spaces which extend above and below said
line of yarn-engaging abutments.
The yarns from the soction-rolls may be "run in" through the reeds in any suitable
manner, and in Figure 6, the arrangement of the yarns relatively to each other and
to the engaging abutments of the reeds is illustrated.
Where four reeds are employed, each yarn abutment, 13, thereof engages overy
fourth yarn, the next three yarns pass freely through the open recd section next to
said abutment, each of said three yarns being engaged by an abutment of one of the
other reeds respectively therefor -for instance, noting the view Figure 6, the
yarn, a, has a free passage through, or non-engagement with, reeds 1, 2, and 3, but
is engaged with the abutment reed 4; yarn a³, has a free passage through reeds 1, 2
and 4, and an engagement with reed 3; yarn a³, has a free passago through reeds 1, 3
and 4, engaging reed 2; and yarn a', has an engagement with reed 1, and a free
passage through reeds 2, 3 and 4; the open reed spaces through which three yarns
of each set of four pass being in a plane next to, but just one side of, the reed
respectively engaging the fourth yarn, and then the successive yarns from the section-
rolls are run through the other reed spaces successively in reduplication of the
arrangement already described, and it will be seen that by raising, say reed 1, every
fourth yarn will be raised, or by raising reeds 1 and 3, every other yarn will be raised,
or half of the yarn, leaving the other half in horizontal lines.
And where four reeds are employed to form the lease the operation may be carried
out as follows, reference being had to Figures 7 and 8 :—
Reeds 1 and 3 are lifted carrying up half the yarns, which are the laternate ones
of all the yarns run through the four reeds, and a separator slide-rod or strip having
a suitable width or height is inserted in advance of all the reeds (and between them
and the foremost guide roll, o) in the shed formed by the said half of the yarn, and
the other relatively intermediate half which has not been raised, as shown at j, and then
the reeds 1 and 3, are permitted to drop to their lowermost position leaving the yarns
which had been raised thereby still forming a slight shed, or one of small height,
extending from the top of said separator-slide back to the rear guide roll a, and this

page_text: position of said yarns which had been raised is also indicated in said Figure 7 by
the dotted line m, and also in Figure 8, by the line m.
Now reeds 2 and 4, are lifted carrying up the other half of the yarns (which
alternate with the first raised half) as indicated by Figure 8, and a decussation is
formed by said yarns, m, which extend under said separator slide j, in its course
from the forward guide roller and upwardly across the lower half of the yarns to the
reed abutments of said reeds 2 and 4, with which said last raised yarns respectively
engage, and as these last raised yarns cross the first manipulated yarns somewhat in
advance of reed 4, a separator slide k, is inserted in the shed next to the said reed 4,
and then when reeds 2 and 4 are also dropped the decussative arrangement which is,
substantially, or which constitutes, the lease, is still maintained, and by replacing for
the said separator slides j and k, cords or other flexible separators, the so relatively
disposed parts may be run through the slasher or dresser and up near to the warp
beam when the portions of the yarn to the rear of both of said separating cords is
severed, and the leased arrangement may then, if desired, be the better secured by
knotting or tying the separated alternate ends, as usual.
Where the number of yarns to be leased is of such a low number that two reeds
only need be employed, the operation, as is obvious, is substantially the same as has
been described, it being understood that the two reeds under the conditions above
set forth, serve to carry the greater number of yarns as the occasion necessitates, but
the movements of pairs in conjunction are, to all intents and purposes, the same as of
a single reed. Therefore, noting Figures 9 and 10, wherein are shown reeds 1 and 2,
every other yarn engaging reed 1, while the relatively intermediate or alternate yarns
are engaged by reed 2, on raising reed 1, as shown in Figure 9, half of the yarns
are lifted forming a shed between them and the lower half, and a separator slide is
inserted well forward of reed 2, and reed 1, is permitted to drop, there still remaining
a slight, but sufficiently clearly defined shed, as indicated by the line, m', in Figures 9
and 10, then raising reed 2, the other half of the yarn is raised, forming the decussa-
tion, or cross-shed in advance of reed 2, and between it and the first inserted separator
slide, as clearly indicated in Figure 10, and the second separator inserted, as also
shown in said Figure 10.
It is plain that after a lease-decussation has been formed in advance of the reeds,
in the manner already described, by then similarly manipulating the reeds forming sheds
extending therefrom to the rear of said reeds, and by the proper insertion of separator
slides, another lease-decussation may be formed at the rear of the reeds. This lease
will be often found advantageous when it is desired to run in new or different kinds
of yarn from different section-rolls through the reeds, for by cutting the yarns at the
rear of the said rear lease, the ends of the new yarn may be readily spliced with, or
twisted upon, the lease-forming ends of the yarns which still remain, by a portion
thereof, through the reeds. This capability largely facilitates the work, for the
running in of the ends, anew, through the reeds is found to be much slower and more
tedious than twisting on or splicing the yarn sections which are already in their
proper relative engagements with the reeds.
In Figure 5, we have illustrated an improved form of reed to be employed, which
consists in forming the reeds alternately with open spaces through its length and
having the relatively intermediate spaces provided with the middle abutments, as has
been already mentioned, but forming the upper end of each reed-rod 10, with a
shoulder or angular projection, 14, which extends towards and to a contact with
the next adjacent reed-rod, but which is not confined to said next adjacent
reed-rod.
The top of each reed-rod shoulder inclines downwardly across the width of said
shoulder meeting the face of the next adjacent reed-rod somewhat below its upper
end. Therefore, in running in the yarns between the reed-rods, instead of hooking
them through the spaces intermediately of the length of the reed, the yarns are
carried in between the ends of the reed-rods which may spring apart sufficiently to
permit of their entrance, the said inclined top surfaces of the reed-rods and their
shoulders permitting the easier and more convenient entrance of the yarns, and the

page_text: said shoulders serve to maintain the proper separation of the rods, the one from the
other, maintaining them all uniformly and preventing their collapsing or binding
upon the yarn. It is preferred to employ a removable cap, n, to cover or enclose the
upper ends of the reed-rods, and also to steady and render more rigid the reed in
its entirety.
'
From the construction indicated in the drawing, Figures 1 and 3, it will be readily
seen that the reed-holding frame F, may be, with the reeds therein, bodily removed
from the common frame D, the levers remaining in said common frame, and with
said reed-carrying frame also may be removed the supporting frame B, and bearings
for the section-rolls to be replaced by a new set of section-rolls carried on a frame
respectively therefor, having also combined therewith a series of lease-forming reeds
and reed-carrying frame. The reced-carrying frame and the section-roll supports are
independently removable, so that by forming a lease between the reeds and the section-
rolls and severing the yarns at the rear of the lease, on removing the section-rolls
and replacing same by other section-rolls, as some occasions may require, and twisting
the ends of the new yarns onto the ends of the leased yarns in the reeds, the work
may be proceeded with as before, it being unnecessary, under this method of
procedure, to equip with every set of section-rolls a separate set of lease-forming
reeds, although usually it is intended so to do, as by this plan the slasher or dresser
may be kept constantly at work, it of course, being understood that the slasher or
dresser consists of a mechanism of much greater expense than the leasing devices,
it at the same time having a capacity for dressing perhaps all the yarn which might
be supplied to it from all the section-rolls in the factory, however great their
number may be. It is therefore deemed expedient to keep the dresser or slasher
always at work, and it is the aim in the preparation of the yarn at the slasher or
dresser to avoid long waits at the times of preparing to run through new series of
yarns.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim, is-
1st. The combination with a slasher or dresser provided with an extension frame,
of a set of reeds, each comprising a series of reed-rods having spaces and abutments
in the arrangement specified, and a carrying frame for said reeds in which said reeds
are vertically movable and guided said reed frame being removably supported on
said extension frame, and a bearing-support for the section-rolls which is also adapted
to be removably connected to and supported on said extension frame, for the purpose
set forth.
2nd. The combination with a slasher or dresser provided with an extension frame,
of a reed guiding frame which has at its opposing sides vertical ways and at its
bottom vertically movable and independent reed-supports, a set of reeds, each reed
thereof comprising a series of reed-rods having spaces and abutments in the arrange-
ment specified and resting on said supports and constrained to move in said vertical
ways a separate lover for each reed-support whereby each reed may be raised and
lowered independently of another, for the purpose set forth.
3rd. In a lease-forming mechanism, substantially as described, a set of reeds cach
of which comprises a series of reed-rods suitably supported, which rods are spaced or
separated from each other and open to their top ends whereby entranco io said spaces
may be had thereat, and every reed-rod having at its upper end an extension or
shoulder 14, projecting against, but unsecured to, the next adjacent reed-rod, the
alternate spaces in each reed being provided intermediate of the lengths thereof, and
below said shoulders, with yarn-engaging abutments, and the relatively intermediate
spaces being free or unobstructed with respect to their middle portions, for the purpose
set forth.
4th. In a lease-forming mechanism, a set of reeds, each reed comprising a series of
reed-rods suitably supported on an outer frame, which rods are spaced or separated
from each other and open to their upper portion whereby entrance. to said spaces may

page_text: he had thereat, and every reed-rod having at its upper end an extension or shoulder 14,
projecting against, but unsecured to, the next adjacent reed-rod, and the top of each
extension or shoulder being obliquely formed, the alternate spaces in each reed
being provided intermediate of the lengths thereof and below the said shoulders with
yarn-engaging abutments and the relatively intermediate spaces being free or
unobstructed with respect to their middle portions, and the movable cap, n, for
covering and steadying the upper extremities of the said reed-rods, for the purpose
set forth.
