Improvements in or relating to Means for Securing Hosiery Machine
Needles, Points or the like to their Supporting and Operating
Devices.
We, GEORGE BLACKBURN, Engineer, and SAMUEL JAMSON, Machinist, both of
Atlas Works, Kirke White Strect, in the City of Nottingham, do hereby declare
the nature of this invention to be as follows:-
This invention refers for example to improved means for securing a hosiery
machine needle to its supporting and operating jack, and is also applicable
generally for attaching like instruments, such as points, to their foundations or
supporting and operating blades or jacks.
The object of this invention is to provide a means of attachment that will
withstand the lateral pressure exerted on the needles or instruments, more
effectively than the means of attachment used heretofore.
According to this invention we form the butt end of the shank of the needle
or instrument, with a longitudinal groove, or form it approximately Ụ shaped
in cross section for a suitable distance, and at the point where it is to be
attached to the jack or metal blade, we form the latter with a fine saw gate
or slit, of about the same width as the thickness of the walls of the grooved
or U shaped butt of the needle, and of preferably a length equal to the said
part of the needle.
One side of this saw gate in the jack is formed with rounded edges, so that
it will enter into the longitudinal groove formed in the needle.
The butt end of the needle is placed in the saw gate in the jack, by first
placing the extreme end of the former, in the outer end of the latter, and then
sliding the needle in till its end is at the bottom of the saw gate.
The sides of the groove in the needle, form cheeks which clasp between them
the substance of the jack on one side of the saw gate, and thus effectively pre-
vent any lateral movement of the needle relatively to the jack.
When placed in the jack in the manner described the needle is further
secured, and prevented from being withdrawn, preferably by soldering it in
this position.
If preferred we may in some cases form the butt end of the shank of the
needle or instrument with two grooves, one being opposite to the other, and in
this case the substance of the jack or metal blade on both sides of the saw gate
is clasped by the sides of the longitudinal grooves in the needle or instrument.
Dated this 4th day of October 1898.

Needles, Points or the like to their Supporting and Operating
Dėvices.
We, GEORGE BLACKBURN, Engineer, and SAMUEL JAMSON, Machinist, both of
Atlas Works, Kirke White Street, in the City of Nottingham, 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, state-
ment:
This invention relates for example, to improved means for securing or attach-
ing a hosiery machine needle to its supporting and operating jack, but it is
also applicable generally for attaching like instruments, such as points, to their
foundations or supporting and operating devices, when the said devices are
formed of thin metal, or metal blades.
The object of this invention is more particularly to provide a means of attach-
ment that will withstand the lateral pressure exerted on the needles or instru-
ments, more effectively than the means of attachment used heretofore.
The invention will be best understood by reference to the accompanying
drawings, in which
Fig. 1 is a side elevation of part of a hosiery machine jack.
Fig. 2 an edge view of the same showing the butt of the needle in section.
Fig. 3 a side view of the needle, and
Fig. 4 a sectional view of the butt of the needle, illustrating our mode of
attachment.
Fig. 5 is a side elevation of part of a hosiery machine jack.
Fig. 6 an edge view of the same showing the butt of the needle in section.
Fig. 7 a side view of the needle, and
Fig. 8 a sectional view of the butt of the needle, illustrating a modification
in our mode of attachment.
Fig. 9 is a side view of a needle showing a different formation of the butt,
and
Fig. 10 an end view of the butt of the same.
The whole of the figures are larger than the actual size of the several parts
which they represent.
Like letters indicate like parts throughout the drawings.
Our invention is shown and described in connection with the attachment of
a hosiery machine needle to its supporting and operating blade or jack.
According to our invention we form the butt end of the shank of the needle A,
(see Figs. 1 to 4) or the part which is inserted in the blade or jack C, with a longi-
tudinal groove B, and the blade or jack C with a saw-gate or opening 1, of a
width which is less than the exterior diameter of the butt of the needle, and
is of any suitable depth.
The edge of one side of this opening D is rounded off or bevelled on both
sides as shown at D in Fig. 1 and 2, so that it will enter the longitudinal
groove B in the needle as shown in Fig. 2.
The butt end of the needle A is placed in the opening D of the jack C, by
first placing the extreme end of the former A, in the outer end of the latter D,
with the edge D₁ in the groove B, and then sliding the needle in till it entirely
fills the opening.
The sides of the grooves B in the needle, it will be seen, form checks which

page_text: clasp the edge D₁ of the opening D, and this effectively prevents any lateral
movement of the needle relatively to the jack.
The needle is further secured and thus prevented from being withdrawn, pre-
ferably by soldering it in the opening in the jack.
If preferred we may form the butt of the needle or instrument A. with two
grooves B B (see Figs. 5 to 8), one groove being placed opposite to the other
as shown.
In this case both edges of the opening D are rounded off or bevelled as shown
at D D in Figs. 5 and 6, and the said edges engage in the respective grooves
in the butt of the needle as shown in Fig. 6.
Instead of forming the butt of the needle with a groove or grooves as
described, we may stamp up or otherwise form, two or more pairs of projec-
tions E on the butt of the needle as shown in Figs. 9 and 10. These projec-
tions E engage with the edge or edges of the opening D in the jack, in precisely
the same manner as the sides of the grooves B, in the arrangement previously
described.
By the means described a needle A or other instrument may be secured in
an excessively thin jack or metal blade, without any risk of it being withdrawn
or pushed out laterally in working, at the same time the thickness of the butt
of the needle need not be in excess of the thickness of the jack or metal blade,
and is thus flush with the surface of the latter and may be used where the
space is limited.
The use of this mode of fastening in the needles or instrument, permits of
the use of thinner jacks or blades, and the latter may therefore be used in
machines of finer gauge than theretofore.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, we declare that
what we claim is:-
1. In the attachment of a hosiery machine needle or other instrument to a
blade or jack; providing the butt of the needle with a groove such as B and
forming the edge of the opening D in the blade or jack to engage in the said
groove substantially as described.
2. In the attachment of a hosiery machine needle or other instrument to a
blade or jack, providing the butt of the needle with grooves such as B B and
forming the edges of the opening D in the blade or jack to engage in the said
grooves substantially as described.
3. In the attachment of a hosiery machine needle or other instrument to a
blade or jack, providing the butt of the needle with two or more pairs of pro-
jections such as E and forming the edge or edges of the openings D in the
blade or jack to engage with the said projections substantially as described.
4. The mode of attaching or securing a hosiery machine needle or other like
instrument to its supporting and operating blade or jack substantially as
described and illustrated in the accompanying drawings.
