PROVISIONAL SPECIFICATION.
Improvements in the Method of and Apparatus for Cutting the
Ends of Fallers.
We, JOHN VAREY, of Jesse Street, Manchester Road, Bradford, in the County
of York, Machine Wool Comb Maker, and WALTER HOLMES of 301 Bowling
Old Lane, Bradford, aforesaid, Mechanic, do hereby declare the nature of this
invention to be as follows:-
The object of this invention is the arrangement and construction of an apparatus
in such a manner, that the ends of fallers used in the preparation of silk, flax, wool
and other fibres may be cut at any angle required to suit the pitch of the travelling
screws, and at the same time grooved for the spring guides by cutting tools operating
simultaneously on the several parts to be reduced.
We accomplish our object in the following manner: Upon a suitable gauntry
are placed two head stocks, one of which is secured thereto, the other movable and
so connected to the fixed head stock, that motion is imparted to the rotating parts
thereof in any position in which it may be required.
Each head stock is fitted with a sliding saddle having an adjustable plate attached
thereto prepared with a straight surface, against which the fallers are secured by a
clip so constructed that, the cutting tools may operate on the angular ends and
grooves for the spring guides.
On securing a faller to the adjustable plates by the before mentioned clips, 'the
necessary angle is obtained for the ends to suit the pitch of the travelling screws
by turning or otherwise adjusting the plates or cutters, so that the faller is at the
requisite angle with the cutting tools, and by the edge of the clips being made
straight and parallel with the fallers, they act as guides for regulating the depth of
cut in the spring guide grooves, and adjustable portion of each cutting tool head
being held in contact with the edge of the clip by a lever to which may be attached
weights or springs.
The travel of the sliding saddles during the cutting operation is effected automa-
tically, and by this arrangement of apparatus the angular and grooved cutting
at both ends is accomplished at the same time, and in such a manner that all the
ends are cut to the same angle and the spring grooves in corresponding positions of
the same depth.

Improvements in the Method of and Apparatus for Cutting the
Ends of Fallers.
We, JOHN VAREY, of Jesse Street, Manchester Road, Bradford, in the County
of York, Machine Wool Comb Maker, and WALTER HOLMES, of 301 Bowling
Old Lane, Bradford aforesaid, Mechanic 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 this invention is the arrangement and combination of certain
mechanism in such a manner that, the ends of fallers used in the preparation of
silk, flax, wool and other fibres, may be cut to any angle to suit the pitch of the
travelling screws of the preparing machine, and at the same time when required,

without having to reset the faller bar, to groove the same for the spring guides by
cutting tools operating simultaneously on the several parts to be reduced.
The invention consists in mounting on a gauntry or other support in a suitable
manner, two head stocks, each provided with a straight faced radial plate combined
with a thin clip for securing the faller bars during the cutting operation at any
angle with the cutters, so that the ends of the bars may be cut at the required
angle to suit the pitch of travelling screws of preparing machines; also arranging
cutters to operate at the same time on the side of each faller to cut parallel grooves
a suitable depth for the spring guides without having to change the position of the
faller bar or fastening device.
In the accompanying drawings
Fig. 1. represents a front elevation of a machine suitable for carrying out our.
invention.
Fig. 2. is a plan thereof.
Fig. 3. a sectional elevation of the apparatus through line a. b.
Fig. 4. a sectional elevation through line c. d. and
Fig. 5. a sectional elevation through line e. f.
Upon a suitable gauntry A. are placed two head stocks constructed in the same
manner, one of which indicated by the letter B. is secured thereto, but the
other B is movable by screw S. so as to adapt the machine for various lengths of
faller bars.
Motion to the rotary cutters is imparted by shaft C. extending the lengths of the
machine, and in each head stock is mounted on the said shaft a bevel wheel D.
gearing with another bevel wheel D' secured on a shaft E. at the opposite end of
which is a spur pinion F. gearing into a spur wheel F secured on a shaft, at
the opposite end of which are fixed a pair of milled circular cutters G. G.
The bracket H. supporting the last named shaft and milled cutters G. G. is
adjustable Fadially on the shaft E. and is secured in the adjusted-position-by one-or
more screws J. engaging with the said bracket and a fixed support K. forming part
of-bed plate-of-head-stock.
The bracket L. supporting the circular milled cutter M. is also adjustable
radially and is supported by the shaft C. on which is mounted a spur pinion N.
gearing into spur wheel N secured on a shaft, to the opposite end of which, is
secured a circular milled cutter M. The bracket L is prepared with a slide plate O.
operated by a screw P. in the same manner as an ordinary slide rest, and is for the
purpose as hereinafter described.
:
Each head stock is provided with a vertical slide plate Q. supported and operated
by a screw R. at the bottom of which is secured a bevel wheel S¹ gearing with
another bevel wheel S2 mounted on shaft. T. extending the length of the machine.
In the vertical slide plate Q. a curved slot hole is formed having a raised curved
and parallel strip of metal Q¹ ou each side, which accurately fits a groove cut in
the adjustable radial plate U. mounted thereon the latter being secured in its
required position by a bolt U provided with a washer so arranged that the thin
clip plate V. is held in the recess formed in the adjustable radial plate U. but may
be slid therein for securing the faller bars Y during the cutting operation.
On each adjustable radial plate U. is mounted a screw W. engaged with a
lever X. fixed at one end to the said adjustable radial plate by a pin and engaged
with the thin clip plate V. by a pin at X' so that, on operating the screw W. the thin
clip plate V. is moved laterally in the recess formed in the adjustable radial
plate U. and is provided with an arm V2 extending downwards the edge of which is
straight and parallel with the hole cut therein for the reception of the faller bars. Y.
and with the face or front edge of the adjustable radial plate against which the
faller bars are secured.
By adjusting the position of the radial plate U. the requisite angle of the faller
bar Y. in relation to the rotating milled cutters G. G. is obtained, and on operating
the screw P. of slide plate O. by the end of the latter being in contact with the
edge of the arm V³ of thin clip plate V. the necessary position of the circular

page_text: milled cutter M. in relation to the faller bar Y. is obtained, the cutter M. operating
on the side of faller bar cuts a groove therein for the spring guide of a depth
regulated by the before mentioned slide which is held in contact with the edge of
arm V by means of lever Z and weight Z¹ or by the aid of springs or other
means.
The travel of the vertical slide plates Q. and connections thereto during the
operation of cutting is effected automatically by means of the coned pullies and
gearing placed at one end of the machine. Motion is imparted from the shaft C.
to the coned pulley 1 by gearing 3. and from coned pulley 1 to 2. by a belt, the
latter pulley being connected by suitable trains of gearing 4 and 5 to the respective
spur wheels 6 and 7. mounted loosely on the shaft T. Each of the last mentioned
spur wheels is provided with a catch box, and between the two a sliding catch
box 8. is mounted on feather keys so that, when the said sliding catch box is in
gear with the spur wheel 6. the shaft T. and the screws R. of vertical slide plates
are operated, thereby causing the vertical slide plates Q. thi clip plates V. and
faller bar Y. to move at a rate suitable to the cutting requirements of the circular
milled cutters.
On the shaft T. is secured a worm 9. gearing into worm wheel 10. on the face of
which are two pins 11. and 12. which, on the rotation of worm wheel 10. operate
the bar 13. in one direction or the other, when pin 11. comes in contact with said
bar and operates it in the direction of arrow, as soon as the incline at end of
lever 14. arrives opposite the pulley 15. a weighted lever or spring acting on the
sliding catch box 8. causes it to move into gear with the catch box of the other spur
wheel 7. and thereby operate the train of gearing 5. connected therewith, which is
so arranged that the rotation of shaft T. is reversed and the speed increased so. that
the vertical slide plates Q. are raised quickly to their original position. The
pin 12. pushes the bar 13. in the opposite direction such a distance that the sliding
catch box 8. is drawn out of gear with wheel 7. thus automatically stopping the
traverse of the vertical slide plates Q. and attachments thereto.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The combination of the parts forming the complete apparatus arranged
substantially as and for the purpose herein before set forth and illustrated by the
accompanying drawings.
2. The combination of the vertical slide plate Q. with the adjustable radial
plate U. and thin clip plate V. for the purpose herein before described.
3. The method of securing the faller bars Y. by a thin clip plate V. or other
attachment gripping the faller bars in such a manner that, the ends of the said bars
may be cut to the angle required and at the same time grooved at the side for the
spring guides.
