WĄ JOSEPH BOOTH and JAMES WOODHOUSE of Hockley Mill, in the Town and
County of the Town of Nottingham, Engineers and Machinists, do hereby declare
the nature of this Invention to be as follows:-
This Invention relates to machinery employed for "whipping" edging or
fringing textile fabrics and it has for its object the improved construction combi-.
nation and arrangement of parts forming such machinery whereby the machine
may be driven more rapidly, with less wear and tear, and with greater steadiness
than is possible with machines as at present commonly constructed.
In carrying out the Invention as applied to machinery for "whipping" or
edging blankets and the like, the needles of the machine are arranged and
operate practically in the usual well known manner and the finger for drawing or
laying the yarn above the blanket or other fabric's edge is carried upon a sliding
horizontal rod or spindle. This spindle, is carried in two bearings upon the
framing or casting having the parts for actuating the needles, and at its inner end
it is fitted by a ball and socket joint to a semi-circular or crescent shaped piece.
This crescent shaped piece fits into a cam groove or race in a ball cam which is
fixed upon the needle motion spindle. This cam is arranged to impart a two and
fro endwise movement to the finger spindle so as to carry its end and the thread
engaged or caught thereby, from needle to needle. A transverse or sideway move-
ment is also given to the finger end by means of a short vertical lever or arm
which has a tubular boss or bearing through which the finger spindle passes and is
free to slide end wise. This tubular boss has a feather or projection inside it which
enters a groove in the finger spindle so that whenever the vertical arm is moved
sideways, the finger spindle is also turned with it. This sideway movement is
caused by a small cam fixed on the needle motion spindle acting against a spring
on a small truck fitted in the upper part of the vertical arm or lever.
A cam
of special form is employed for actuating the needle pressers operating on the
horizontal bearded needle underneath whereby a dead pressure is exerted on the
needle.

page_text: When employing the Invention for machinery for fringing textile fabrics the
spindle for actuating the finger is preferably placed at a lower level say parallel
with the spindle operating the lower needle and parts. In this case the to and fro
end wise motion of the finger spindle is imparted through the medium of a vertical
lever having the ball and socket joint at its upper end and centered near the
middle of its length. The side way motion of the finger may be imparted by the
short vertical lever or arm operated on by a cam fixed on the lower needle shaft.
The. improved machinery may be adapted to form a narrower or deeper stitch
by fitting the eye needle nearer to the bearded needle or further from it as
required.

We, JOSEPH BOOTH and JAMES WOODHOUSE of Hockley Mill, in the Town and
County of Nottingham Engineers and Machinists 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 machinery employed for "whipping" edging or
fringing textile fabrics and it has for its object the improved construction, combi-
nation and arrangement of parts forming such machinery, whereby the machines
may be driven more rapidly, with less wear and tear, and with greater steadiness
than is possible with the machines as at present commonly constructed.

In carrying out the invention as applied to machinery for "whipping
edging blankets and the like, the needles of the machine are arranged and operate
practically as in the usual well known manner, and the finger for drawing or
laying the yarn above the blanket or other fabrics edge is carried upon a sliding
horizontal rod or spindle. This spindle is carried in two bearings upon the
framing or casting having the parts for actuating the needles, and at its inner end
it is fitted by a ball and socket joint to a semi-circular or crescent shaped clip or
fork. This crescent shaped piece fits into a cam-groove or race in a ball cam which
is fixed upon the needle motion spindle.
This cam is arranged to impart a reciprocatory movement to the finger spindle,
so as to carry its end and the thread engaged or caught thereby, from needle to
needle. A transverse or sideway movement is also given to the finger end by
means of a short vertical lever or arm which has a boss or bearing through which
the finger spindle passes and is free to slide end wise.
In the interior of this boss is a feather or projection which enters a slot or key-
bed in the finger spindle so that whenever the vertical arm is rocked or moved
sideways, the finger spindle is also turned with it. This sideway movement is caused
by a cam fixed on the needle motion spindle, acting against a spring on a branch
arm fitted to the upper part of the vertical arm or lever.
A suitable cam is employed for actuating the needle-presser operating on the
horizontal bearded needle underneath, whereby a dead pressure is exerted on the
needle.
When employing the invention for machinery for fringing textile fabrics, the
spindle for actuating the finger is preferably placed at a lower level, say, parallel
with the spindle operating the lower needle and parts. In this case the recipro-
catory motion of the finger spindle is imparted through the medium of a lever
formed with a ball working in a socket joint at its lower end and fulcrummed
near the middle of its length. The sideway motion of the finger may be imparted
by the short vertical lever or arm, operated on by a cam fixed on the lower needle
shaft.
The improved machinery may be adapted to form a narrower or deeper stitch
by fitting the eye needle nearer to the bearded needle or further from it as

front elevation, Figure 3 a plan, Figures 4 and 5 elevation and plan of the cam and
Figure 6 side elevation of a portion of the clip or fork thereof.
In carrying out this invention as applied to machinery for "whipping" or
edging blankets and the like the needles A of the machine are arranged and
operated substantially as in the usual manner.
The finger B for drawing or laying the yarn above the edge of the blanket or
other fabric is carried upon a horizontal rod or spindle B¹. This spindle B¹ is
carried in two bearings B formed on the framing or casting supporting the parts
for actuating the needles A and at its inner end it is fitted by a ball and socket
joint C to a semi-circular or crescent shaped pieco. D. This crescent shaped piece D
fits into a cam groove or race E in a ball cam F fixed upon the needle motion
spindle. The groove in this cam F is arranged to impart a reciprocatory move-
ment to the finger spindle B' so as to carry the end of the finger and the thread
engaged or caught thereby from needle to needle.
A transverse or sideway movement is also given to the end of the finger B by
means of a short vertical lever or arm G secured to the finger spindle B¹.
This sideway movement is caused by a cam H fixed on the needle motion spindle
which is of such a width as to allow the lever G to move with the finger spindle
without slipping off. The lever or arm G is fitted at its upper end with a ball or
runner I working freely in the lever G and on the cam H a spiral spring J being
attached to the upper part of the lever to keep the ball in contact with the cam.
Instead of the lever G being fixed on the spindle B¹ it may slide on a feather in
which case the cam H need be no wider than the runner I.
A cam K of suitable form is employed for actuating the needle presser L
operating on the vertical bearded needle whereby a dead pressure is exerted.
When employing the invention for fringing textile fabrics the spindle for
actuating the finger B is preferably placed at a lower level; in this case the to and
fro end wise motion of the finger spindle B¹ is imparted through the medium of a
vertical lever having the ball and socket joint at its lower end and centered near
the middle of its length. The sideway motion of the finger may be imparted by a
short vertical lever or arm operated on by a cam fixed on the lower shaft M.
The improved machine may be adapted to form a narrower stitch by fixing the
two needles closer together.

Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1.--In a machine such as described the combination of a cam such as F with
clutch fork D fitting into a socket joint C for imparting a reciprocatory motion
to finger shaft B₁ substantially as specified and illustrated in the accompany
drawings.
2. In a machine such as described the combination of a finger B, for laying the
yarn, with a shaft B¹ having reciprocatory and oscillatory motion imparted to it
by cam F and fork D substantially as specified and illustrated in the accompanying
sheet of drawings.
