PROVISIONAL SPECIFICATION.
Improvements relating to Loom Lays and Reeds.
I, JOSEPH WILLIAM CHENEY of 43 Front Street, in Three Rivers, in the
Town of Palmer, County of Hampden, and State of Massachusetts, United States
of America, Superintendent, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in the construction and arrangement of
the lay-beam and reed of a loom.
The object of the invention is to provide a reed which shall be as efficient as
heretofore for beating-up, and which shall, moreover, be unusually desirable by
reason of the greater elasticity or yielding capability of its reed-rods whereby they
may spread, one from the other, at the plane of the race-surface or board of the
lay-beam, to permit the free passage of lumpy or knotted warp yarns through
the reed.
To this end the invention consists in the combination with the lay-beam, of the
reed having its lower edge supported thereby with the race-surface or board of the
lay-beam which ranges across the reed at a plane intermediate between the ends of
the reed-rods; and in carrying out the invention there is necessarily no departure
from the usual construction of the reed itself which comprises as common, the dents
or reed-rods and the bead-like connections therefor at top and bottom thereof; the
lay-beam is step-formed at its rear upper portion and upon the base of this step
the bottom of the reed is supported, being there held in place by suitable clamping
devices.
The race-board or race-surface has its rear edge cut away or reduced so as to
be free from frictional contact with the adjacent reed-rods.
The race-board or upper lay-beam surface which constitutes the race-way for the
shuttle, is, in practice, to be nearly an inch above the united lower extremities of
the reed-rods so that the warp-yarns are supported to pass through the reed at a
plane above the bottom of the reed, at which plane a very desirable and important
degree of yielding or elastic capability is present.
I provide an adjustable strip along the lay-beam against which the rear of the
lower edge portion of the reed is to lie, and against which it is held by the reed-
clamp.
The strip is adjustable transversely so as to accord with the different widths of
the beaded lower edges of the various reeds which may be employed.
Dated this Fourteenth day of February 1893.

COMPLETE SPECIFICATION.
Improvements relating to Loom Lays and Reeds.
I, JOSEPH WILLIAM CHENEY of 43 Front Street, in Three Rivers, in the
Town of Palmer, County of Hampden, and State of Massachusetts, United States
of America, Superintendent, 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 improvements in the construction and arrangement of
the lay-beam and reed of a loom.

page_text: The object of the invention is to provide a reed which shall be as efficient as
heretofore for battening, and which shall, moreover, be unusually desirable by
reason of the greater elasticity or yielding capability of the reed-dents whereby
they may be free to spread, one from the other, opposite the edge of the race-board,
to permit the free passage (and without liability of breakage) of lumpy or knotted
warp yarns through the reed.
To this end the invention consists in the combination with the lay-beam, of the
reed having its lower rib. supported thereby, and supporting the dents thereof
separated from the edge of the race-board of the lay-beam which ranges along the
side of the reed at a plane intermediately of the reed-ribs, and all as will hereinafter
fully appear and be set forth in the claims.
In the drawings,
Figure 1 is a vertical cross sectional view through the lay-beam and reed.
Figure 2 is a plan view of the same below the reed-cap.
In the drawings, A represents the lay-beam which is understood as mounted to
have reciprocatory movements, as usual, and B represents the reed which comprises
the usual dents and border ribs.
The lay-beam is step-formed at its. rear upper portion, as seen at and upon the
base of this step the lower rib of the reed is supported, being there held in place
by the clamp devices indicated by the strip, x, and bolt, ; and the reed-cap, b; as
usual, overlies the reed.
d represents the race-board which is screwed upon the top of the lay-beam, just
forward of the reed, and its rear edge is cut away so that this board will be free
from frictional contact with the adjacent dents, or the latter are adjusted by the
below described devices, so that they are held normally away from the adjoining
edge of the race-board, d.
It will be here observed that the upper part of the lay-beam is to be regarded as
the race-board, or race-surface, whether it be a board separately formed and
attached, as indicated, or whether integrally formed with the body of the lay-beam.
This race-board, or upper lay-beam surface, is, in practice, to be about an inch
and one-half, more or less, above the lower extremities of the reed-dents, so that
the warp yarns are supported to pass through the reed at a plane above the bottom
of the reed, at which plane a very desirable and important degree of yielding or
elastic capability is present, as shown in Figure 1, the edge of the race-board, d,
adjoining the reed extends beyond the plane of the vertical wall of the lay-beam
beneath it, overhanging the front side of the lower reed-rib.
In this improved arrangement great advantage is gained by the increased facility
with which knotted or lumpy warp yarns, designedly or accidentally so formed,
may pass between the free dents of the reed and be incorporated into the fabric by
the loom, without liability of breakage in transit, through the reed.
It will be perceived in Figure 1 that the vertical wall of the step of the lay-beam
has a longitudinal groove or depression, f, into which is let a strip, g, of iron or
other suitable material and which strip is adjustable transversely toward and from
the lower reed-rib by one or more screws, h, and a corresponding adjustment of the
strip, x, is provided for. Thus the lay-beam is adapted for the reception of reeds
having the lower rib thereof of varying thicknesses.
For a thin rib the screws are forwardly moved to move the strip, g, against the
lower rib within the groove, while if the rib is of greater diameter or thickness the
strip enters the groove further, and ail to the end of having the reed with
the battening edge of its dents always in a plane parallel to the shuttle track.
This arrangement also permits the adjustment of the reed so that it may be
exactly in the plane at right angles to the run of the warp.
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:
1. In a loom, the lay-beam having a depression at its rear, a transversely

page_text: adjustable strip in the vertical face of said depression engaging one side of the
lower rib of the reed, and clamping devices, substantially as described, engaging
the opposite side of said rib and securing the same to the lay-beam, combined and
operating substantially as set forth.
2. In a loom, in combination, the reed, the lay-beam having a depression at its
rear, reed-rib clamping devices, as and, securing the lower rib of the reed to
the lay, and an adjustable front bearing for said rib in the vertical wall of said
depression whereby the dents of the reed are adjusted and maintained in a position
away from the edge of the race-board of the lay; combined and operating sub-
stantially as set forth.
3. In a loom, the step-formed lay-beam having the groove, f, the strip, g, within
said groove, one or more adjusting screws therefor, the reed, and clamping devices,
substantially as described, securing the lower rib of the reed to the beam, combined
and operating substantially as set forth.
4. In a loom, the lay-beam having a depression at its rear, a longitudinal bearing
for the lower reed-rib on the vertical face of said depression, and clamping devices,
substantially as described, engaging the opposite side of said rib and securing the
same to the lay-beam, combined and operating substantially as set forth.
5. In a loom, the lay-beam having a depression at its rear, a longitudinal bearing
for the lower reed-rib on the vertical face of said depression, the race-board having
its edge opposite the reed-dents, projecting beyond the vertical face of said
depression, and clamping devices, substantially as described, engaging the opposite.
side of said rib and securing the same to the lay-beam, combined and operating
substantially as set forth.
6. In a loom, the combination of the lay-beam, the reed extending down past the
top of said beam, and means for adjusting said reed toward or away from the race-
board on the beam, all combined substantially as described.
