We, GEORGE FREDERICK BANCROFT, of 36 St. Ignatius Square, Preston, in the
County of Lancaster, Cotton Mill Manager, and SAMUEL HOPKINSON, of 10 Brook
Street North, in the same town, Joiner and Ślay Maker, do hereby declare the nature
of this invention to be as follows:-
This invention has reference to the stop rod mechanism of loose reed looms. We
make the stop rod of square bar iron or steel with rounded necks at intervals for the
bearings which we prefer to be about twice the usual width. The bearings consist of
a metal plate or bracket fastened to the underside and also to the front side of the
slay, the front part of the plate being turned upwards so that the pull or resistance
to the backward thrust of the stop rod may be received upon the front part of the
slay. The other end of the plate is turned down and on its further side has a semi-
circular recess forming one half of the bearing for the stop rod, the other half being
provided by a correspondingly recessed cap plate which is fastened on to the hanging
down part of the bracket by a screw bolt and nut. By this arrangement the cap
plate receives the blow or pressure of the stop rod during the locking operation and
by filing down projecting ribs or setting-up pieces on the inner side of the cap plate
the play caused by wear and tear may be taken up as required.
We make the duck bill " carriers in the form of brackets which may be fixed in
position or removed without moving the stop rod from its bearings and so constructed
that the back portion of the bracket (to which the reed case is attached) may be
adjustable vertically.
To this end the duck bill bracket made in two pieces, the front portion having a
rectangular groove which is slipped sidewise on to the square stop rod, the back
portion fitting up to the stop rod, and the two portions being drawn together and
fastened by a screw bolt and nut, suitable slots being provided so that the back
portion may be raised or lowered for the purpose of adjusting the vertical position of
the reed case relatively to the slay as required. The space between the stop rod and
the front side of the slay sword we fill up by introducing a curved bearing piece
fastened to the flat side of the stop rod by means of a screw-threaded pin which is
passed through a hole in the stop rod and answers as the projecting arm for connecting
to the ordinary taking-up spring.

page_text: The duck bill is fastened to the lower portion of the duck bill bracket and passes
under a "heater" in the usual manner.
We preferably form the heater so as to have four inclined flat sides or rubbing
surfaces in such manner as to be reversible and thus provide four surfaces to receive
in turn as they become worn the wear and tear from the friction of the duck bill
instead of only one surface as in ordinary arrangements. The heater is mounted on
the lower horizontal projecting part of a flat vertical arm fastened at its upper end to
the cloth carrier, and we interpose a locking piece between the upper end of the flat
arm and the vertical face of the cloth carrier plate. The locking piece is devised so
that the heater arm may be straight and stand perpendicularly instead of being
"swan-necked as ordinarily arranged and also to prevent the heater arm from being
forced sidewise or twisted out of position by the pressure of the duck bill underneath
being provided on its lower horizontal edge with projecting ears which fit against the
lower edge of the cloth carrier plate, the front of the locking piece having a vertical
recess into which the upper end of the heater arm fits, a screw bolt and nut fastening
the heater arm and locking device to the cloth carrier.
"
Any required number of our improved stop rod bearings or duck bills and heaters
as above described may be employed for the purpose of imparting the requisite
pressure to the back of the reed case, and the duck bill brackets may, if thought
desirable, be arranged in pairs side by side so that the strain may be divided between
the two at any given point.

page_text: We, GEORGE FREDERICK BANCROFT of 36 St. Ignatius Square Preston in the
County of Lancaster, Cotton Mill Manager and SAMUEL HOPKINSON of 10 Brook
Street North in the same Town Joiner and Slay Maker 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 has reference to the stop rod mechanism of loose reed looms. In
the accompanying Drawings,
Figure 1 is a front view.
Figure 2 a back view and
Figure 3 a plan view of so much of the slay apparatus of an ordinary loom as is
necessary to illustrate the nature of our Invention.
We make the stop rod a of square bar iron or steel with rounded necks at intervals
for the bearings b which we prefer to be about twice the usual width. The bearings may
consist of a metal plate or bracket c (see Figure 5) fastened to the underside and also to
the front side of the slay d the front part of the plate c being turned upwards so that the
pull or resistance to the backward thrust of the stop rod a may be received upon the front
part of the slay. The other end of the plate may be turned down and on its further side
have a semi-circular recess forming one half of the bearing for the stop rod, the other
half being provided by a correspondingly recessed cap plate which may be fastened on to
the hanging down part of the bracket by a screw bolt and nut. By this arrangement
the cap plate receives the blow or pressure of the stop rod during the locking
operation and by filing down projecting ribs or setting up pieces on the inner side of
the cap plate the play caused by wear and tear may be taken up as required. In lieu
of the cap plate as above described we prefer to employ the arrangement shown at
Figure 5 in which the stop rod a is left square at the bearings instead of being turned
down so as to be made round and thus reduced in diameter. e is a shell open on one
side so that it may be slipped on to the stop rod and rounded on the other to answer
as the bearing being held in position by means of ears or lugs f on each side within
the supporting piece g fastened to the metal plate c by a screw bolt and nut as shewn
and which takes the place of the cap plate hereinbefore referred to. In another
arrangement the bearer 6' is formed so that the part c may be movable and by means
of a regulating screw bolt and nut c¹ the relative positions of the stop rod a and the
slay d may be varied as required.
We make the "duck bill" carriers in the form of brackets h which may be fixed in
position or removed without moving the stop rod a from its bearings and so con-
structed that the back portion of the bracket (to which the reed case i is attached)
may be adjustable vertically-To this end the duck bill bracket is made in two pieces,
the front portion having a rectangular groove which is slipped sidewise on to the
square stop rod (see Figure 4) the back portion fitting up to the stop rod, and the
two portions being drawn together and fastened by a screw bolt and nut, suitable
slots being provided so that the back portion may be raised or lowered for the purpose

page_text: of adjusting the vertical position of the reed case i relatively to the slay d as
required The space between the stop rod and the front side of the slay sword w we
fill up by introducing a curved bearing piece j (see Figure 3) fastened to the flat side
of the stop rod by means of a screw threaded pin which is passed through a hole in
the stop rod and answers as the projecting arm for connecting to the ordinary taking
up spring. Or, the arrangement shewn in Figures 1. 2 and 3 may be adopted by
forming on the same casting a hook k which may receive the top of the taking up
spring and a bracket / having a regulating screw m the point of which rests against
the front of the slay sword wand by which the position of the stop rod and reed case
may be adjusted.
The duck bill o is fastened to the lower portion of the duck bill bracket / and
passes under a "heater "p in the usual manner.
We preferably form the heater so as to have four inclined flat sides or rubbing
surfaces (see Figures 3 and 4) in such manner as to be reversible and thus provide
four surfaces to receive in turn as they become worn the wear and tear from the
friction of the duck bill instead of only one surface as in ordinary arrangements. The
heater p is mounted on the lower horizontal projecting part of a flat vertical arm q
fastened at its upper end to the cloth carrier r and we interpose a locking piece s
between the upper end of the flat arm and the vertical face of the cloth carrier plate.
The locking piece is devised so that the heater arm may be straight and stand perpen-
dicularly instead of being "swan-necked" as ordinarily arranged and also to prevent
the heater arm from being forced side-wise or twisted out of position by the pressure
of the duck bill underneath we provided it on its lower horizontal edge with projecting
ears tt (see Figure 4) which fit against the lower edge of the cloth carrier plate, the
front of the locking piece having a vertical recess into which the upper end of the
heater arm q fits (as shewn in Figures 3 and 4) a screw bolt and nut fastening
the heater arm g and locking devices to the cloth carrier.
Any required number of our improved stop rod bearings or duck bills and heaters
as above described may be employed for the purpose of imparting the requisite
pressure to the back of the reed case, and the duck bill brackets may, if thought
desirable, be arranged in pairs side by side (as shewn towards the right hand side of
Figures 1, 2, and 3) so that the strain may be divided between the two at any given
point.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed we declare that what we claim is :-
1. The use or employment in loose reed looms of stop rod apparatus in which the
bearings and duck bill brackets are made in two pieces bolted together so as to be
detachable and replaceable without disturbing the position of the stop rod substantially
as described and shewn in the Drawings.
2. The reversible heater p having four wearing surfaces constructed substantially
as described and shewn in the Drawings.
3. The use or employment of a curved bearing piece j introduced between the slay
sword and the stop rod substantially as described and shewn in the Drawings.
4. The combination of parts constituting the improved stop rod apparatus for use
in loose reed looms constructed and arranged substantially as described and shewn in
the Drawings for the purpose or purposes set forth.
Dated this 29th day of July 1887.
