Year: 1876

page_text: LETTERS PATENT to Thomas Hattersley, of Leeds, in the County of York,
Spindle Manufacturer, for the Invention of "AN IMPROVED MANUFACTURE OF
TUBE ROVING FLYERS."
Sealed the 24th April 1877, and dated the 16th November 1876.

Office of the Commissioners of Patents on the 16th November 1876.

AN IMPROVED MANUFACTURE OF TUBE ROVING FLYERS."
The object of this Invention is to construct what are known as tube roving flyers
of steel instead of iron, the advantage of which material both in respect of lightness,
strength, and durability has been long appreciated. Attempts have already been
made to employ this material in the manufacture of tube roving flyers, but
hitherto with no practical success.
The difficulties presented to the manufacturer I now propose to overcome by
operating in the following manner :-I take a bar of steel, either flat, bevel, or any
other shape, in which the breadth exceeds the thickness of sufficient length and
thickness to provide metal for the formation of the shoulders and legs of the flyer,
and to the centre of this piece, on one or both sides thereof, I attach by welding
a cylindrical lump of steel or iron which is to form the socket of the flyer, and Ĭ
thus produce a flyer blank.
Those parts of the blank which are close to the socket are now subjected to a
process of fullering in order to spread out the metal at these points to the requisite
breadth, and prepare it for the next operation of drawing out the legs.
The ends of the flyer blank, which are to form the legs of the flyer, I next
elongate and reduce to the proper thickness by rolling or hammering the same
while at a red heat, applying the pressure when rolling from the centre to the ends
of the metal. I now subject the metal to the process of annealing in order to
restore the ductile quality of the steel lost in the preceding operation.
The next operation is to drill and turn the socket which is to receive the spindle
at one end and form a guide for the rose at the other. The metal having been
sufficiently extended by rolling or hammering, I trim the edges thereof so as to
bring the plate to the requisite size and form for the tube required.

page_text: By means of dies or swages I now give a trough like shape to the rolled out
metal. The flyer is now in a condition to be blocked to shape by bending down the
legs and bringing them parallel or nearly so to each other. The flyer is then
finished in the usual manner, after which all the parts liable to wear are hardened.
or tempered. Tubular flyers thus made will from their lightness and stiffness admit
of being driven at a greater speed than those of the ordinary construction.

"AN IMPROVED MANUFACTURE OF TUBE ROVING FLYERS."
"
The object of this Invention is to construct what are known as "tube roving
flyers of steel instead of iron, the advantage of which material both in respect of
lightness, strength, and durability has been long appreciated. Attempts have
already been made to employ this material in the manufacture of tube roving flyers,
but hitherto with no practical success.
The difficulties presented to the manufacturer I now propose to overcome by
operating in the following manner:-I take a piece of a bar of steel of sufficient
length, breadth, and thickness to provide metal for the formation of the shoulders
and legs of the flyer, and to the centre of this piece, on one or both sides thereof,
I attach by welding a cylindrical lump of steel or iron, which is to form the socket
of the flyer, having previously reduced the breadth of the said piece of steel in the
centre thereof by fullering, and I thus produce a flyer blank.
In the accompanying Drawing Figures 1 and 2 represent in side and end views at
half scale a length of bar steel suitable for forming an ordinary ten inch traverse
flyer.
Figure 3 shews in plan view the steel fullered in the middle and with a central
hole drilled therein. The object of this fullering is to reduce the quantity of metal
at the welding part, so that there is no more than is required to fill the welding
dies, and by this means a more secure joint is effected as well as a saving of material.
The central hole is drilled to receive an iron peg, which is passed through it for con-
necting together the cylindrical lumps which are to form the sockets preparatory to
their being welded to the steel bar.
Figs. 4 illustrate this attachment of the parts, a being the steel bar; b, b, the
lumps, and c the metal peg which pins the lumps together ready for welding.
When the flyer blank is thus put together it is raised to a welding heat and sub-
mitted to suitable dies which weld the parts together, and at the same time prepare
the bar a for the next operation.
The parts
** of the blank, which are close to the socket, are now subjected to a
process of fullering in order to spread out the metal at these points to the requisite
breadth, and preparing it for the next operation of drawing out the legs.
The ends of the flyer blank, which are to form the legs of the flyer, I next elongate
and reduce to the proper thickness by rolling or hammering the same while at a
red heat, applying the pressure when rolling from the centre to the ends of the
metal. After this I subject the metal to the process of annealing in order to restore
the ductile quality of the steel lost in the preceding operations.
The next step in the manufacture is to drill and turn the socket which is to
receive the spindle at one end and form a guide for the rove at the other.
The metal which is to form the legs of the flyer having been sufficently extended by
rolling or hammering, I trim the edges thereof so as to bring it to the requisite size
and form to produce the tubular legs required.
By means of dies or swages I now give a trough like shape to the rolled out

page_text: metal according to the manner usually practised in making tubular flyers. At this
stage the flyer is in a condition to be blocked to shape, which consists in bending
down the legs and bringing them parallel or nearly so to each other. I then
finish the flyer in the usual manner, after which I harden or temper it to give
strength and firmness to the whole and durability to the working parts. Tubular
flyers thus made will from their lightness and stiffness admit of being driven at a
greater speed than those of the ordinary construction.
Having now set forth the nature of my Invention of "An Improved Manufacture
of Tube Roving Flyers," and explained the manner of carrying the same into effect,
I wish it to be understood that under the above in part recited Letters Patent, I
claim,—Manufacturing steel tube roving flyers from blanks prepared as described
with reference to the accompanying Drawing, such manufacture being carried out
as and for the purpose above set forth.
In witness whereof, I, the said Thomas Hattersley, have hereunto set my
hand and seal, this Twelfth day of May, in the year of our Lord One
thousand eight hundred and seventy-seven.
