We JOHN RILEY of Boothroyd Lane Dewsbury mechanic, and JOSIAH ELAM of
Ashwood Road Dewsbury mechanic both in the County of York do hereby declare
the nature of this invention to be as follows:-
The object of our Invention is to provide a simpler motion for whipping and edgeing
machines than those at present in use, and which shall therefore be less liable to get
out of order and will require fewer repairs.
Our improved motion consists of a carriage, sliding in suitable guides fixed to the
underside of the machine table. This sliding carriage moved to and fro by means
of a connecting rod or link, attached at one end to a pin on a horizontal cam and
crank disc, the disc being keyed or otherwise fixed on a vertical shaft driven from
some moving part of the machine.
"
""
The upper side of this cam and crank disc contains a grooved cam, in which works
a runner or friction wheel fixed to one end of a two armed lever. The opposite
end of the lever fits a groove or recess formed in a box on the upper side of the sliding
carriage. This lever rocks about a stud fixed in the under side of the machine table.
The lever however is not centred or fixed to the stud, but is provided with a short
transverse groove or slot hole, which passes over the end of the stud. The above
mentioned box on the upper side of the sliding carriage is so arranged, that it not
only moves to and fro with the sliding carriage, but can oscillate about a stud passing
through and attached to the sliding carriage. The motion imparted by the cam to
the lever is thus modified, the lever sliding transversely, so that the fixed stud or
centre is first at one end. and then at the other end of the cross slot of the lever.
It will be seen, that the free end of the lever forms a moving guide for the before
mentioned box on the upper side of the sliding carriage. A stud, fixed on the top
side of this box, carries the finger used for drawing the thread from one needle to the
other. The irregular intermittent motion imparted to the finger during each rotation
of the vertical shaft before mentioned, is thus the result of the reciprocating motion
imparted by the crank, combined with the oscillating motion produced by the cam
and lever action above described.

page_text: An Improved Motion for Whipping or Edgeing Machines.
We JOHN RILEY of Boothroyd Lane Dewsbury mechanic, and JOSIAH ELAM of
Ashwood Road Dewsbury mechanic both in the County of York 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 :-
The object of our Invention is to provide a simpler motion for whipping and
edgeing machines, than those at present in use, and which shall therefore be less
liable to get out of order and will require fewer repairs.
Our improved motion consists of a carriage sliding in suitable guides fixed to the
underside of the machine table. This sliding carriage is moved to and fro by
means of a connecting rod or link, attached at one end to a pin on a horizontal
cam and crank disc, the disc being keyed or otherwise fixed on a vertical shaft
driven from some moving part of the machine.
The upper side of this cam and crank disc contains a grooved cam, in which
works a "runner" or friction wheel fixed to one end of a two armed lever. The
opposite end of the lever fits a groove or recess formed in a box on the upper side of
the sliding carriage. This lever rocks about a stud fixed in the underside of the
machine table. The lever however is not centred or fixed to the stud, but is provided
with a short transverse groove or slot hole, which passes over the end of the stud.
The above mentioned box on the upper side of the sliding carriage is so arranged,
that it not only moves to and fro with the sliding carriage, but can oscillate about a
stud passing through and attached to the sliding carriage. The motion imparted by
the cam to the lever is thus modified, the lever sliding transversely, so that the fixed
stud or centre is first at one end and then at the other end of the cross slot of the
lever.
It will be seen that the free end for the lever forms a moving guide of the before
mentioned box on the upper side of the sliding carriage. A stud fixed on the top side
of this box, carries the finger used for drawing the thread from one needle to the
other. The irregular continuous motion iniparted to the finger during each rotation
of the vertical shaft before mentioned, is thus the result of the reciprocating motion
imparted by the crank, combined with the oscillating motion produced by the cam
and lever action above described.
And in order that, our Invention may be more completely understood reference 18
given to the accompanying drawings and to the letters and marks thereon.
Fig. 1 is a side elevation and Fig. 2 is a plan looking upwards at the underside of 35
a whipping and edgeing machine having our improvements applied thereto.
Our improved motion or mechanism consists of a carriage a, sliding in suitable
guides b, fixed to the underside of the machine table c. This sliding carriage a

page_text: is moved to and fro by means of a connecting rod or link d, attached at one end
to a pin on a horizontal disc e, the disc being keyed or otherwise fixed on a
vertical shaft f driven from some moving part of the machine.

"
Above this crank disc and keyed or otherwise fixed to the same vertical shaft f
is a horizontal grooved cam disc g, in which works a runner or friction wheel
fixed to one end of a two armed lever h. The opposite end of the lever h fits a groove
or recess formed in a box i (shewn by dotted lines in both figures) on the upper side
of the sliding carriage a. This lever rocks about a stud k fixed in the under side of
the machine table c. The lever h however is not centred or fixed to the stud but is
provided with a short transverse slot hole as shewn through which the stud k passes.
The above mentioned box i on the upper side of the sliding carriage a is so arranged
that it not only moves to and fro with the sliding carriage a, but can oscillate about a
stud m passing through and attached to the sliding carriage. The motion imparted
by the cam g to the lever his thus modified, the lever sliding transversely, so that
the fixed stud k is first at one end and then at the other end of the cross slot in the
lever h.
It will be seen that the free end of the lever h forms a moving guide for the before
mentioned box i on the upper side of the sliding carriage a. A stud m² fixed on the
top side of this box, carries the finger (shewn in dotted lines in the plan) used for
drawing the thread from one needle to the other. The needles are not shewn in the
drawings. The continuous irregular motion imparted to the finger during each
rotation of the vertical shaft is thus the result of the reciprocating motion imparted
from the crank disc e combined with the oscillating motion produced by the cam and
lever action above described.
A further detail of our improved motion consists in attaching to the same vertical
shaft fa cam n, which operates the lever o, such lever carrying at its extremity the
presser p which presses against and closes the hook needle during the upward motion
of the latter, through the needle slot q. A set screw in the end of the lever o is kept
pressed against the cam n by means of the spring s.
One of the principal advantages obtained by the use of our improved motion is that
the movement of the finger is continuous instead of intermittent so that the strain on
the yarn is more uniform.
Having now more 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°. The sliding carriage a, carrying the finger l, and actuated from the crank disc e,
in combination with the oscillating box i actuated by the cam disc g and lever h, all for
the purpose of imparting a continuous irregular motion to the end of the finger 1,
substantially as herein described and shewn in the accompanying drawings.
2°. The sliding carriage a carrying the needle finger l'and actuated from the crank
disc e for the purpose of imparting a to and fro motion to the finger / substantially as
and for the purpose herein set forth, and all as shewn in the accompanying drawings.
3°. The oscillating box i worked by the hinged lever h, (having a cross slot) from
the cam g, for the purpose of imparting a reciprocating cross motion to the end of
the finger 1, substantially as and for the purpose herein set forth and as shewn in the
accompanying drawings.
