IMPROVEMENTS IN THE MODE OF SECURING SHEET METAL COVERINGS TO SHED OR LEASE RODS EMPLOYED IN LOOMS FOR WEAVING, AND IN APPARATUS THEREFOR." PROVISIONAL SP
Year: 1880

page_text: LETTERS PATENT to Robert Moss, of Preston, in the County of Lancaster, for
an Invention of "IMPROVEMENTS IN THE MODE OF SECURING SHEET METAL
COVERINGS TO SHED OR LEASE RODS EMPLOYED IN LOOMS FOR WEAVING,
AND IN APPARATUS THEREFOR."
PROVISIONAL SPECIFICATION left by the said Robert Moss at the Office
of the Commissioners of Patents on the 13th May 1880.
ROBERT Moss, of Preston, in the County of Lancaster. "IMPROVEMENTS IN THE
MODE OF SECURING SHEET METAL COVERINGS TO SHED OR LEASE RODS
EMPLOYED IN LOOMS FOR WEAVING, AND IN APPARATUS THEREFOR."
This Invention relates to improvements in the mode of securing sheet metal
coverings to "shed" or "lease" rods employed in looms for weaving, and in
apparatus therefor, and is applicable to the form or section of "shed rod" described
in the Specification of Letters Patent granted to Richard Tomlinson and Robert
Moss, No. 2207, A.D. 1873. The main feature of my Invention consists in
employing suitably formed dies of metal through which the wood shed rod, having
on each of its curved sides a strip of sheet metal, is passed or drawn. The first die
through which the rod and strips of sheet metal are passed is so formed as to cause
the projecting edges of the sheet metal to be turned in so as to grip the edges of
the wood rod. The operation of passing or drawing the wood rod and strips of
sheet metal through the first die may be performed by hand, and is merely intended
to fix the sheet metal strips in position upon the wood rod previous to their being
permanently secured thereto. This I effect by drawing the metal-covered shed rod
through a second die, having its aperture in section the size of the shed rod in its
finished state. The resistance in drawing the rod through the second die being
more than can be practically overcome by hand, I employ a chain and wince
mechanism actuated by steam or other suitable motive power; the end of the shed
rod being first passed through the die, and then grasped by a pair of draw tongs
attached to the end of the chain. The barrel upon which the chain is wound is so
arranged in conjunction with an engaging and disengaging clutch or catch box,
that the operator may, by pressing his foot upon a suitably mounted lever, set the
chain barrel in motion, thereby winding on the chain and drawing the rod through
the die, or may put the chain barrel out of action, so that the chain may be
unwound at will.

ROBERT Moss, of Preston, in the County of Lancaster. "IMPROVEMENTS IN THE
MODE OF SECURING SHEET METAL COVERINGS TO SHED OR LEASE RODS
EMPLOYED IN LOOMS FOR WEAVING, AND IN APPARATUS THEREFOR."
This Invention relates to improvements in the mode of securing sheet metal
coverings to "shed" or "lease" rods employed in looms for weaving, and in
apparatus therefor, and is applicable to the form or section of "shed rod" described
in the Specification of Letters Patent granted to Richard Tomlinson and Robert
Moss, No. 2207, A.D. 1873. The main feature of my Invention consists in
employing suitably formed dies of metal through which the wood shed rod, having
on each of its curved sides a strip of sheet metal, is passed or drawn. The first die
through which the rod and strips of sheet metal are passed is so formed as to
cause the projecting edges of the sheet metal to be turned in so as to grip the edges
of the wood rod. The operation of passing or drawing the wood rod and strips of
sheet metal through the first die may be performed by hand, and is merely intended
to fix the sheet metal strips in position upon the wood rod previous to their being
permanently secured thereto. This I effect by drawing the metal covered shed rod
through a second die, having its aperture in section the size of the shed rod in its
finished state. The resistance in drawing the rod through the second die being
more than can be practicably overcome by hand, I employ a chain and wince
mechanism actuated by steam or other suitable motive power; the end of the shed
rod being first pressed through the die, and then grasped by a pair of draw tongs
attached to the end of the chain. The barrel upon which the chain is wound is so
arranged in conjunction with an engaging and disengaging clutch or catch box,
that the operator may, by pressing his foot upon a suitably mounted lever, set the
chain barrel in motion, thereby winding on the chain and drawing the rod through
the die, or may put the chain barrel out of action so that the chain may be
unwound at will.
In the accompanying Drawings, Figs. 1 and 2 are sections of a large and small
size shed rod, and Figs. 3 and 4 are end views of the dies employed for each size.
Figs. 5 and 6 are plan views of Figs. 3 and 4 respectively. In the case of the
larger sized shed rods, I prefer to attach the sheet metal first to one side of the rod
and then to the other, and employ in such case a die formed to receive only one
side of the shed rod, as shewn in Figs. 3 and 5. The smaller sizes may have the
sheet metal strips attached to both sides at one operation by being passed through
dies in the form shewn in Figs. 4 and 6. The sheet metal coverings are first
curved to the shape of the curved sides of the wood to be covered, and are then
drawn one on each side of the rod through a die, as shewn at Fig. 7, the edges of
the sheet metal a being thereby turned in so as to lap over the edges of the wood
rod b.
Figs. 8 and 9 are side and plan views, and Fig. 10 an end view of apparatus for
effecting the second or finishing operation. A is a metal table on stands B. To
one end of the table A is attached the frame or bracket C carrying the chain and
wince mechanism.
The chain barrel d is loose upon a shaft e actuated through the medium of the
geared wheelf by the pinion g on the shaft h. i is a toothed catch box turning
with the shaft e, but capable of lateral motion, so as to allow of its being brought
into gear with the teeth j on the chain barrel d, when the latter will revolve with
the catch box i and wind up the chain h. is a pair of draw tongs grasping the

page_text: shed rod m and drawing it through the die n, which is placed behind a stop o
provided with the opening 8.
The catch box i may be caused to engage with the chain barrel d by hand by
means of the handle p, or by the foot by pressing the lever q; a spiral spring
being so arranged as to bring the catch box i out of gear on releasing the handle p,
or when pressure on the lever q is withdrawn.
The dies may be of any suitable metal, such as brass, cast or wrought iron, steel,
or steel castings.
Having now described the nature of my said Invention, and the manner in which
it may be brought into practical effect, I would have it understood that I do not
intend to claim any of the mechanical parts of the apparatus herein before described
and shewn when taken separately, and apart from the combination or application
thereof, in manner and for the purposes herein described, but what I consider to be
novel and original, and claim as secured to me under the Letters Patent herein-
before in part recited is,-
1. The mode of attaching sheet metal coverings to lease or shed rods by the
employment of dies, substantially as described.
2. The constructing apparatus for drawing lease or shed rods having sheet metal
coverings through a die, substantially as described and illustrated.
In witness whereof, I, the said Robert Moss, have hereunto set my hand and
seal, this Ninth day of November, in the year of our Lord One thousand
eight hundred and eighty.
ROBERT MOSS. (L.S.)
