page_text: 1, FRANK ASHTON, of Hargreaves Spindle Works, Oldham, in the County of
Lancaster, Manager of Spindle Works, do hereby declare the nature of this inven-
tion to be as follows:-
My invention relates to a method of reproducing in any desired numbers surfaces
of particular form or shape by means of an enlarged counterpart or copy of the
surface to be reproduced, and is more particularly adapted to the rounding off of
the side roving holes in flyer sockets, as used in cotton woollen or flax spinning
and preparing machinery.
The apparatus consists of a table on which are fixed two slides, a front slide
and a back slide, the front and back slides are operated, either by means of a screw
shaft with two different pitches of screws or by levers, in such a manner that for
a given movement of the screw shaft, or the lever, the back slide moves over four
times the distance which the front slide moves over. The above mentioned table
is also so constructed as to allow of a swinging motion around both a horizontal
and a vertical axis.
To the before mentioned front slide is fixed the flyer or other article to be
operated upon, and on the back slide, at a distance from the above mentioned
vertical axis of four times the distance of the centre of the roving hole in the flyer
from the vertical axis, is placed an enlarged copy of the desired surface, this copy
being four times the size of the form of surface to be duplicated.
Above the centre of the roving hole is a hemispherical end milling cutter
mounted in fixed bearings. This cutter whilst revolving works all over the surface
to be rounded off, by the enlarged counter-part of the desired surface being passed
over an enlarged counterpart of the milling cutter which has also a hemispherical
end but has no cutting teeth formed on its surface.
In this manner is reproduced an exact copy on a reduced scale of the enlarged
form or surface, and any number of fac-similes of the desired surface can be pro-
duced.
I do not confine myself to the above described ratio of 1 to 4 between the article
and the enlarged counterpart thereof, as 1 may evidently take any other ratio
which may be found convenient.

page_text: I, FRANK ASHTON, of Hargreaves Spindle Works, Oldham, in the County of
Lancaster, Manager of Spindle Works, 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 a method of reproducing in any desired numbers sur-
faces of particular form or shape by means of an enlarged counterpart or copy of
the surface to be reproduced, and is more particularly adapted to the rounding off
of the side roving holes in flyer sockets, as used in cotton woollen or flax spinning
and preparing machinery.
My invention will be readily understood from the following description on
reference to the accompanying drawings of which Fig. 1 is a side elevation, and
Fig. 2 an end elevation of a machine for rounding off the side roving holes in
flyer sockets.
The apparatus consists of a table a on which are fixed two slides, a front slide b
and a back slide b, the front and back slides are operated, either by means of a
screw shaft with two different pitches of screws c and c¹ (or by levers), in such a
manner that for a given movement of the screw shaft c c by rotating the handle c³,
or by moving the lever, the back slide & moves over four times the distance which
the front slide b moves over. The above mentioned table a is also so constructed
as to allow of a swinging motion around both a horizontal axis a¹ and a vertical
axis a as shown at Fig. 1.
To the before mentioned front slide is fixed the flyer d as shewn (or other
article to be operated upon), and on the back slide b', at a distance from the above
mentioned vertical axis a' of four times the distance of the centre of the roving
hole c in the flyer d from the vertical axis a', is placed an enlarged copy e¹ of
the desired surface, this copy el being four times the size of the form of surface to
be duplicated; i.e. the rounded roving hole e.
Above the centre of the roving hole e is a hemispherical rotating end milling
cutter mounted in suitable fixed bearings, not shewn on the drawings. This
cutter whilst revolving works all over the surface e to be rounded off, by the
enlarged counter-part c of the desired surface being passed over an enlarged
counterpart of the milling cutter f which has also a hemispherical end but has
no cutting teeth formed on its surface, the part fl with its bracket f being fixed
to the frame or stand supporting the table and its axes, this motion is accom-
plished by moving the table a by the handle a on its axes a and a² as desired
and by moving the slides bb by turning the screw shaft cel by the said handle.
In this manner is reproduced an exact copy on a reduced scale of the enlarged
form or surface (in the case illustrated a rounded roving hole in the flyer socket d)
and any number of fac-similes of the desired surface can be produced.
1 do not confine myself to the above described ratio of 1 to 4 between the
article and the enlarged counterpart thereof, as I may evidently take any other
ratio which may be found convenient.
gg are springs supporting the rear end of the swinging table a, i is a spring
pin or peg engaging with the roving holes on the lower side of the flyer and steady-
ing the latter while the hole at the upper side is being rounded off.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is
The improved profiling apparatus consisting of the two slides the enlarged

page_text: counterpart of the desired form, cutter and enlarged counterpart of the cutter
arranged and operating substantially as hereinbefore described.
