PROVISIONAL SPECIFICATION.
An Improved Pile-wire for Looms.
I, GUSTAV SEGSCHNEIDER, Mechanic of Yonkers, Westchester County, State
of New York, United States of America, do hereby declare the nature of this
nvention to be as follows:-
This invention relates to certain improvements in pile wires for looms of that
class in which pile fabrics are woven said improvements relating more specially to
the construction of a holder for the cutting blade and its connection with the pile
wire proper, whereby not only the cutting blades can be readily inserted and
removed but also old pile wires utilized by attaching new holders and cutting
blades thereto and the invention consists of the combination with a pile wire of a
holder that is attached to the end of same said holder being provided with means
for retaining the cutting blade.
The invention consists further of a holder for the cutting blades of pile wires
which is made of suitable sheet metal and bent into shape so as to form a heel for
retaining the cutting blade in connection with a spring that is inserted into the
shank of the holder.
The invention consists further of a holder for the cutting blades of pile wires
which is provided at the outer end with a curved guard that is made integral with
the holder and with an abutment or heel for the cutting blade and with a longi-
tudinal slot at the inner end by which the holder is attached to the recessed end of
the pile wire as will be fully described hereinafter and finally pointed out in the
claims.

Similar letters of reference indicate corresponding parts throughout.
Referring to the drawings:-A represents a pile wire and B a blade supporting
holder which is made of suitable sheet metal advantageously of sheet steel.
The holder B is made from a blank B' which is shown in Fig. 6 the width of the
blank being equal to twice the height of the holder plus the width of the base of
the same so that when the blank is bent up into shape a rigid support for the
cutting blade is obtained.
The end of the pile wire A is provided at both sides with recesses a which are

of slightly less height than the height of the pile wire and with a tongue a¹ that
forms an extension of the recessed portion.
The inner end or shank of the holder B is provided with a longitudinal slot b
the width of the slot being equal to the thickness of the recessed end of the
pile wire A so that when the tongue a¹ of the shank is inserted into the inner end
of the holder B the side walls of the holder can be readily brazed, soldered or
otherwise fastened to the recessed end of the pile wire the lower part of the end of
the pile wire abutting against the lower inner end of the holder as shown clearly
in Fig. 1.
The outer end of the blank B' (Fig. 6) is provided with a curved lug d and
adjacent to the lug with a recess d and at the opposite side of the blank with a
projection d² which takes into the recess d¹ when the blank is folded up so as to
form the holder B. The projection d forms then the heel or abutment against
- which the blunt outer edge of the blade C rests.
The inner sharpened and tapering end of the cutting blade C is retained in
position by a spring D which is brazed soldered rivetted or otherwise suitably
fastened to the shank of the holder B the free end of the spring extending over the
tapering end of the blade so as to retain the blade in connection with the heel or
abutment firmly in position.
The lug d is curved away from the longitudinal plane of the holder as shown in
Fig. 2 so as to form a guard by which the end of the holder B does not interfere
with the reeds during the ingoing motion of the pile wire. The slight curve
imparted to the guard d produces the ready glancing off of the end of the holder
from the reeds in case it should catch or abut against the same and secures thereby
the reliable working of the pile wire in its motion from one side of the loom to the
other
The blade C is made of triangular shape with an outer edge a blunt base and a
slanting and sharpened inner edge to which a hard temper is imparted after grinding.
The blade C is inserted into the open top part of the holder by first inserting
the tapering end of the blade below the spring and then moving it outward until
the blunt end of the blade abuts against the heel d² in which position the blade is
rigidly held in position by the spring and heel. On removing the blade either for
sharpening or for inserting a new blade the inverse operation is performed.
In place of inserting the pile wire through the open upper part of the holder the
holder can also be made from the blank B' shown in Fig. 9 in which case the holder
is open at the lower part and the blade also inserted from the open bottom part of
the same. In this case the middle portion of the blank is provided with a longi-
tudinal slot e through which the blade extends it being inserted by putting the
tapering end of the same over the outer end of the spring D then passing the apex
and upper part of the blade through the slot e which is at the top part of the
holder and next moving the blade outwardly until its blunt outer edge rests on the
bent over projection d2 and against the outer end of the slot e as shown in Figs. 7
and 8. The modified form of sheet metal holder is attached by its slotted inner
end or shank by brazing or otherwise to the recessed end of the pile wire in the
same manner as when the holder is closed at the bottom and open at the top.
In place of retaining the blade C in the holder B by a spring attached to the
inner end or shank, of the holder B the blade can also be retained by arranging a
spring hook D¹ at the outer end of the holder which hook is made like the guard d
integral with the holder and bent over at the inner end of the hook as shown, in
Figs. 13 and 15 so as to engage the somewhat elongated outer blunt and rounded
off end of the blade as shown in Fig. 13. The spring hook D' retains the blade C
rigidly in the holder B the blade being readily inserted and removed by means of
pliers. The rounded off outer end of the blade is inserted against the tension of
the spring hook until arrested by the heel d2 at the outer end of the holder which
together with the spring hook forms a reliable retaining device for the blade. The
inner end or shank of the holder B is attached to the recessed end of the pile
wire A as before described.

page_text: My improved construction of pile wire has the advantage that all the old pile
wires in use instead of being cast aside can be used with my removable cutting
blade by simply cutting off the outer end of the pile wire and attaching the sheet
metal holder to the same secondly that the holder being stamped from suitable
sheet metal can be readily bent into shape by machinery and supplied independently
of the pile wires so as to be ready for attachment to the same whenever required
thirdly that the holder and the cutting blade can be furnished with the pile wire at
less expense than the pile wires heretofore in use in which the retaining devices for
the cutting blade are arranged in the outer end of the pile wire which takes longer
time and is more expensive than the manufacture of the separate holder for the
blade and its attachment to the pile wire and lastly that owing to the high temper
that can be imparted to the separate blade a great amount of material can be cut
by one and the same blade and in an even and uniform manner as the yarn being
level with the top of the wire is stretched tightly over the blade when the cutting
action takes place.

Referring to the drawings:-A represent a pile-wire and B a blade supporting
holder which is made of suitable sheet metal advantageously of sheet steel.
The holder B is made from a blank B' which is shown in Fig. 6 the width of the
blank being equal to twice the height of the holder plus the width of the base of
the same so that when the blank is bent up into shape a rigid'support for the cutting
blade is obtained.
The end of the pile-wire A is provided at both sides with recesses a which are of
slightly less height than the height of the pile-wire and with a tongue a¹ that forms
an extension of the recessed portion.
"
The inner end or shank of the holder B is provided with a longitudinal slot 6 the
width of the slot being equal to the thickness of the recessed end of the pile-wire A
so that when the tongue a¹ of the shank is inserted into the inner end of the
holder B the side walls of the holder can be readily brazed soldered or otherwise
fastened to the recessed end of the pile-wire the lower part of the end of the
pile-wire abutting against the lower inner end of the holder as shown clearly
in Fig. 1..
The outer end of the blank B¹ (Fig. 6) is provided with a curved lug d and
adjacent to the lug with a recess d¹ and at the opposite side of the blank with a
projection d' which takes into the recess d¹ when the blank is folded up so as to
form the holder B. The projection d2 forms then the heel or abutment against
which the blunt outer edge of the blade C rests.
The inner sharpened and tapering end of the cutting blade C is retained in
position by a spring D which is brazed soldered rivetted or otherwise suitably
fastened to the shank of the holder B the free end of the spring extending over the
tapering end of the blade so as to retain the blade in connection with the heel or
abutment d² firmly in position.
The lug d is curved away from the longitudinal plane of the holder as shown in
Fig. 2 so as to form a guard by which the end of the holder B does not interfere
with the reeds during the ingoing motion of the pile-wire. The slight curve
imparted to the guard d produces the ready glancing off of the end of the holder
from the reeds in case it should catch or abut against the same and secures thereby
the reliable working of the pile-wire in its motion from one side of the loom to the
'other.
The blade C is made of triangular shape with an outer edge a blunt base and a
slanting and sharpened inner edge to which a hard temper is imparted after
grinding.
The blade C is inserted into the open top part of the holder by first inserting the
tapering end of the blade below the spring and then moving it outward until the
blunt end of the blade abuts against the heel d2 in which position the blade is
rigidly held in position by the spring and heel. On removing the blade either for
sharpening or for inserting a new blade the inverse operation is performed.
In place of inserting the pile-wire through the open upper part of the holder the
holder can also be made from the blank B shown in Fig. 9 in which case the holder
is open at the lower part and the blade also inserted from the open bottom part of
the same.
In this case the middle portion of the blank is provided with a
longitudinal slot e through which the blade extends it being inserted by putting the

page_text: tapering end of the same over the outer end of the spring D then passing the apex.
and upper part of the blade through the slot e which is at the top part of the-
holder and next moving the blade outwardly until its blunt outer edge rests on the-
bent over projection d and against the outer end of the slot e as shown in Figs. 7
and 8. The modified form of sheet metal holder is attached by its slotted inner end
or shank by brazing or otherwise to the recessed end of the pile-wire in the same.

In place of retaining the blade C in the holder B by a spring attached to the
inner end or shank of the holder B the blade can also be retained by arranging a
spring hook D' at the outer end of the holder which hook is made like the guard d
integral with the holder and bent over at the inner end of the hook as shown in

rigidly in the holder B the blade being readily inserted and removed by means of
pliers. The rounded off outer end of the blade is inserted against the tension of
the spring hook until arrested by the heel d2 at the outer end of the holder-which
together with the spring hook forms a reliable retaining device for the blade. The-
inner end or shank of the holder B is attached to the recessed end of the pile-wire A
as before described.
My improved construction of pile-wire has the advantage that all the old pile-
wires in use instead of-being cast aside can be used with my removable cutting-
blade by simply cutting off the outer end of the pile-wire and attaching the sheet.
