We, EDWARD SIMPSON, of the Glasgow Spindle Works, Rutherglen, in the
County of Lanark, North Britain, Spindle and Tool Manufacturer, and JOHN MOFIE,
of the same place Mechanic do hereby declare the nature of the said Invention for
'IMPROVEMENTS IN FLYERS USED IN ROVING, SPINNING, TWISTING, DOUBLING AND
WINDING FIBROUS MATERIALS" to be as follows:-
"
This Invention has for its objects to render more durable certain parts of flyers
used in roving, spinning, twisting, doubling, and winding fibrous materials; and
to facilitate the changing or renewal of the same parts.
The parts to which the Invention, more particularly, relates, are the palms and
guide eyes at the ends of the flyer legs in which parts as ordinarily inade grooves
are soon worn by the yarn or thread such grooves sometimes becoming deep
enough to catch and hold the yarn or thread. The entire palm cannot conveniently
be made of very hard steel because of the brittleness of such material and the
consequent risk of breakage; but by the present Invention whilst the external
part of the palin is made of tough but comparatively soft iron or steel, the guide
eye is formed in a separate pieco or bush or eyelet of extremely hard steel, or of
carthenware, or glass, or other sufficiently hard substance of a nature to be not
easily worn by the yarn or thread. A socket is formed in the palm to receive the
guide eye bush which is by preference of a cylindrical form externally, and which
may be in the form of a complete ring, a slit or opening is, however, by preference
formed through the bush and through the end of the palm to facilitato the
insertion of the yarn or thread. The guide eye bush is secured in its place by a
spring pin, or by a small screw which may be applied in various ways, or by a
taper key, or by being screwed into its socket.
On the accompanying sheet of explanatory drawings, figures, 1 and 2, are
sectional side and edgeway elevations of a flyer fitted with the improved guide eye
bushes; and figures, 3 to 7, illustrate variations in the mode of securing the bushes
in their places.
In carrying out the Invention each palm, P, has bored or formed in it a
cylindrical hole or socket of a larger size than the hole which would be made to
serve itself as the guide eye; and the guide eye is formed in a separate piece or
bush E, shaped externally to fit the hole or socket in the palm, P. The edges of

page_text: the eye in the bush E are of the usual rounded form so as to act with as little
friction as possible on the yarn or thread; and a slit or opening, S, is formed
through the end of the palm and into the guide eye.
For securing the bush, E, in its socket, as shown in figures 1 and 2, thero is
provided a pin, N, made with a conical outer end and fitted to work in a socket
drilled for it in the palm, P. A small helical spring is placed on a tenon or
reduced part of the pin, N, to press it towards the bush E, and in the bush, E, a
small indentation is formed for the conical end of the pin, N, to enter. When the
bush E, is pressed towards the inner or outer side of the palm, P, with sufficient
force the pin N, recedes and allows the bush to be entered or removed. A small
angular groove is made in the bush at, G, leading to the recess for the pin and
facilitates the entering of the bush into its place. A small screw, C, may be used
for securing the bush, E, as shown in figures 3, 4, and 5, which illustrate this mode
of fixing by different examples. In figure, 6, the application of a taper key or
pin, K, is shown, this mode of fixing being well suited for, holding a guide eye
bush, E, of earthenware, glass, or the like; and in the example shown in figure, 7,
a screw thread is formed on the outside of the bush E, and a corresponding
internal thread being formed in the socket in the palm, P, the bush is screwed
into its place.

page_text: We, EDWARD SIMPSON, of the Glasgow Spindle Works, Rutherglen, in the
County of Lanark, North Britain, Spindle and Tool Manufacturer, and JOHN
MCFIE of the same place, Mechanic, do hereby declare the nature of our Baid
invention for "IMPROVEMENTS IN FLYERS USED IN ROVING, SPINNING, TWISTING,
DOUBLING, AND WINDING FIBROUS MATERIALS" and in what manner the same is
to be performed, to be particularly described and ascertained in and by tho
following statement that is to say :-
Our said Invention has for its objects to render more durable certain parts of
flyers used in roving, spinning, twisting, doubling, and winding fibrous materials;
and to facilitate the changing or renewal of the same parts.
The parts to which the Invention, more particularly, relates, are the palms and
guide eyes at the ends of the flyer legs, in which parts as ordinarily made grooves
are soon worn by the yarn or thread such grooves sometimes becoming deep
enough to catch and hold the yarn or thread. The entire palm cannot, con-
veniently be made of very hard steel because of the brittleness of such material
and the consequent risk of breakage; but by the present Invention whilst the
external part of the palm is made of tough but comparatively soft iron or steel, tho
guide eye is formed in a separate piece or bush or eyelet of extremely hard steel,
or of earthenware, or glass, or other sufficiently hard substance of a nature to be
not easily worn by the yarn or thread. A socket is formed in the palm to receive
the guide eye bush which is by preference of a cylindrical form externally, and
which may be in the form of a complete ring, a slit or opening is, however, by
preference formed through the bush and through the end of the palm to facilitato
the insertion of the yarn or thread. The guide eye bush is secured in its place by
a spring pin, or by a small screw which may be applied in various ways, or by a
taper key, or by being screwed into its socket.
On the accompanying sheet of explanatory drawings figures, 1, and 2, aro
sectional side and edgeway elevations of a flyer fitted with the improved guide eye
bushes; and figures, 3, to 7, illustrate, variations in the mode of securing the
bushes in their places.
In carrying out the Invention each palm, P, has bored or formed in it a
cylindrical hole or socket of a larger size than the hole which would be made to
serve itself as the guide eye; and the guide eye is formed in a separate piece or
bush, E, shaped externally to fit the hole or socket in the palm, P. The edges of
the eye in the bush, E, are of the usual rounded form so as to act with as littlo
friction as possible on the yarn or thread; and a slit or opening, S, is formed
through the end of the palm and into the guide eye.
For securing the bush, E, in its socket, as shown in figures, 1, and 2, there is
provided a pin, N, made with a conical outer end and fitted to work in a socket
drilled for it in the palm, P. A small helical spring is placed on a tenon or
reduced part of the pin, N, to press it towards the bush, E; and in the bush, E,
a small indentation is formed for the conical end of the pin, N, to enter.
The eye
in the bush, E, is formed eccentrically so that the bush may be thicker opposite
the slit, S, that is at the part where the indentation is formed for the entrance of
the pin, N, to lock the pin in its place. We proposed to form a small angular
groove in the circumferential surface of the bush, E, and leading into the
indentation but we now prefer to make the bush without such groove and so avoid
any risk of the bush getting displaced; and to facilitate the entering of the

page_text: bush, E, into its place we provide a small instrument shown in figures, 8, 9, and 10,
which comprise two end views and a side view. This instrument consists of a
round pin easily fitting the socket in the palm, P, and formed with a groove
having an inclined bottom which forces inwards the spring pin, N, when the
instrument is pushed through the socket. The bush, E, is placed on an eccentric
stud at the end of the instrument and is pressed so as to push the instrument
through the socket and take its place, the pin, N, springing out into the indentation
and locking the bush.
A small screw, C, may be used for securing the bush, E, as shown in figures, 3, 4,
and 5, which illustrate this mode of fixing by different examples. In figure, 6, the
application of a taper key or pin, K, is shown, this mode of fixing being well suited
for holding a guide eye bush, E, of earthenware, glass, or the like; and in the
example shown in figure, 7, a screw thread is formed on the outside of the bush, E,
and a corresponding internal thread being formed in the socket in the palm, P, the
bush is screwed into its place.
We do not restrict ourselves to the precise details herein described or delineated
provided that the distinctive features of our Invention are retained,-these being,
1, the securing of the bush or eyelet by means of the spring pin, as described with
reference to figures, 1, and 2; 2, the securing of the bush or eyelet by means of a
screw as described with reference to figures, 3, 4, and 5; 3, the securing of the
bush or eyelet by means of a taper key as described with reference to figure, 6;.
4, the securing of the bush or oyelet by screwing it into its socket as described
-with-reference-to-figure, 7-;-and-5,-the-eccentric-form-of-the-bush-or-eyelet.
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
