I, ROBERT HOLT WISEMAN of Bank House Barrowford near Burnley in the
County of Lancaster Manufacturer do hereby declare the nature of my inven-
tion for IMPROVEMENTS IN « BOATS OR WARP SELVEDGE CARRIERS EMPLOYED
IN WEAVING PLAIN SELVEDGES ON TWILLED AND SIMILAR FABRICS to be as
follows:-
This Invention relates to the "boats" employed in weaving plain selvedges on
twilled and similar fabrics and has for its objects to avoid the necessity of
removing the "boat" from the loom every time that the warp is changed, to
reduce the number of "boats" required for each loom and to reduce the amount
of trouble at present involved in taking up the selvedge warp. threads.
These Improvements consist in constructing the "boat" entirely of metal in the
following or a similar manner. Upon a sleeve or boss is cast or otherwise secured
two wings or arms opposite to each other and at right angles to the sleeve or boss.
At the outer end of each arm or wing is fixed parallel with the sleeve or boss, a
short rake having four or more teeth. Parallel with each rake and preferably
between the rake and the boss or sleeve there is also fixed or secured to each wing
or arm, a light rod guide or retaining bar. The selvedge warp threads are passed
between the teeth of the two rakes and are prevented from falling out by the
light rods or guides. The "boat ".is pivoted upon a pin attached to the loom side
and is free to oscillate on this pin as the yarn moves in shedding.
"
"Boats constructed according to these Improvements enable the Twister to
handle a twill warp with no more trouble than an ordinary plain warp while
only two are required for each loom instead of two to each set of gearing as
at present.

Improvements in " Boats or Warp Selvedge Carriers Employed
in Weaving Plain Selvedges on Twilled and similar Fabrics.
I, ROBERT HOLT WISEMAN of Bank House, Barrowford near Burnley in the
County of Lancaster, Manufacturer do hereby declare the nature of this inven-
tion, and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
My invention relates to the "boats" employed in weaving plain selvedges on
twilled and similar fabrics, more particularly on twilled fabrics woven with three
or five shafts. These boats are ordinarily composed of long loops of flat wire
fastened into pieces of leather nailed to the ends of the arms of a short two armed
wooden lever. The warp threads for forming the selvedges are threaded alter-
nately through these loops at the one or the other end, in consequence of which
the boats have to be removed from the loom with the warp every time the warp
is changed and two boats are required for each set of gearing. Sometimes these
long loops of flat wire are slit on one side near the end where they are fastened
in the leather, so that the warp threads may be inserted or taken out through
these slits when the warp is changed. This however is an inconvenient operation,
as each thread has to be handled singly and each loop of flat wire opened
separately.
My improvements have for their object to avoid the necessity of removing the
boats with the warp every time the latter is changed and to reduce the amount
of trouble at present involved in threading the boats and in taking up the selvedge
warp threads.
In order that my improvements may be readily ascertained and carried out,
I have hereunto appended a sheet of drawings marked with letters of reference.
Figure 1 shows a side view of my improved boat, figure 2 an end view and figure 3
& view of the same as seen from below.
My improved boat is constructed entirely of metal in the following manner :
Upon a sleeve or boss a two. wings or arms b¹ 6' are cast or otherwise fixed at
right angles to the sleeve or boss and nearly opposite to each other so as to
enclose an obtuse angle. At the outer end of each arm or wing b¹ and b² a short
rake c¹ and having four or more teeth is cast on or otherwise fixed parallel with
the sleeve or boss a. Parallel with each rake and preferably between such rake
and the boss or sleeve a there is also cast on or otherwise fixed to each arm b¹
and 6' a light rod or retaining bar d¹ and d². The selvedge warp threads are passed
alternately between the teeth of the rakes c¹ and c. The boat is pivoted upon
a pin attached to the loom side and is free to oscillate on this pin as the warp
moves in shedding.
The action of my improved boats on the selvedge warp threads while weaving
is identical with that of the boats previously in use.
The rods or retaining
bars d¹ and d prevent the threads from dropping out of the teeth when the warp
is slack.

a twill warp with no more trouble than an ordinary plain warp and 'two boats
only are required for each loom.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
The construction of "boats" or selvedge warp carriers substantially as herein-
before described and shewn on the drawings.
