PROVISIONAL SPECIFICATION.
Improvements in connection with the Manufacture of Glass Headed
Pins, and in the Means to be Employed therefor.
We WILLIAM HALL & CO. LIMITED of The Central Works Studley in the
County of Warwick Needle and Fish Hook Manufacturers and ALFRED BANKS
of Park Road Redditch in the County of Worcester Manager do hereby declare
the nature of this invention to be as follows:-
This invention relates to an improved method of knobbing or heading the pins.
Hitherto it has been the usual practice when attaching the molten glass which
forms the knob or head to hold the pin by hand until the knob is cool enough to
admit of its being laid down without affecting the spherical shape of same this
obviously entails an expenditure of time in the manufacture.
Our improvements consist in the use of a metal plate of any suitable size and
shape preferably of a disc like form, cut in the periphery of which are suitably
shaped long narrow angular slits which lead to and terminate in circular holes in the
metal plate which are bevilled or sunk upon their upper sides to form seatings for
the after mentioned purpose.
The said metal plate is carried by a screw threaded vertical spindle and adjusting
screw nut and washer upon which it revolves horizontally, the spindle is screwed
into or otherwise attached at its base to a stand or table, beneath the revolving
metal plate is a projecting stationary lever arm also carried by the said spindle and
at a right angle thereto and retained by a screw nut.
The operation is thus. The molten glass knobs or heads having been attached
to the pins, it is now required to mould the same and to preserve their spherical
shape, the pins therefore are passed vertically into the above described narrow slits
in the plate where they are finally received in the holes provided for the purpose;
the knobs or heads seating themselves in the bevilled or sunken sides of same, where
they are allowed to remain until cool.
In order to remove the pins, by revolving the moulding plate upon the spindle
they are caused to be thrown off by their coming individually into contact with the
said lever arm, which it may be stated projects somewhat beyond the periphery
of the revolving plate and which catches them in turn and pushes them out of their
individual angular slits thus obviating the necessity of their removal by hand.
By this means the knobs or heads are attached to the pins and perfectly
moulded.
When other than spherical knobs are required the said holes will be formed of
the necessary shape to turn out the same.
The size of the angular slits and holes may vary according to the size of the pins
and their heads.
Thus a great saving of time and labour is effected whereby the pins can be
manufactured in far less time and of more perfect formation than by methods
hitherto adopted.

Pins, and in the Means to be Employed therefor.
We WILLIAM HALL & Co. LTD. of The Central Works Studley in the
County of Warwick Needle and Fish Hook Manufacturers, and ALFRED BANKS
of Park Road Redditch in the County of Worcester Manager, 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,
reference being had to the drawings accompanying this Specification and to the
figures and letters shewn thereon :-
Our invention relates to an improved method of knobbing or heading glass
headed pins.
Hitherto it has been the usual practice when attaching the molten glass which
forms the knobs or heads, to hold the pins by hand in a blast of cold air until the
knobs are cool enough to admit of their being laid down without affecting the
spherical shape of same; this obviously entails an expenditure of time and
labour in their manufacture.
We obviate these disadvantages by the use and application of an apparatus
comprising a horizontal revolving metal plate having narrow slits or apertures
cut therein at convenient angles and of a curved or straight form this revolving
plate works upon a vertical spindle or upright screwed into or otherwise attached
at its base to a stand or table of any suitable description, the spindle also carries
a lever arm which is connected to same at right angles thereon and is located
beneath the revolving plate.
We will now proceed to fully describe our invention and its operation.
In the drawings
Figure 1. represents in plan the revolving metal plate and lever arm.
Figure 2 is the spindle and its attachments in connection therewith and the stand
or base we prefer to use.
Figure 3 is a plan of the lever arm.
Figure 4 represents an elevation of the apparatus complete.
Figure 5 is a similar view shewing how the pins are cast off the revolving plate
by contact with the lever.
A. is the revolving metal plate of any suitable size and shape but preferably of
a disc like form, cut in the periphery of this metal plate A. at suitable distances
apart are conveniently shaped narrow curved or straight slits or apertures B,
converging towards one another at a suitable angle relatively to each other and the
spindle, each section of metal in which the slits or apertures are cut is curved
outwardly and rounded off at its extreme end B', the slits or apertures lead to and
terminate in circular holes C. which are preferably bevilled or sunk on their upper
edges in order to form seatings for the after mentioned purpose.
Or the slits may
be formed on the slant and terminate quite straight.
The said metal plate A. is carried by a screw threaded vertical spindle or
support D. and adjusting screw nut and washer E. F. and upon which the plate A.
revolves horizontally, the spindle is screwed into or otherwise attached at its base
to a table or stand G, placed upon a table, beneath the revolving metal plate A. is
the projecting lever arm H attached at right angles to the spindle D. and may either
be permanently fixed thereon or retained in place by a screw nut I.
The operation is thus. The molten glass knobs or heads having been attached
to the pins it is now required to mould the same and to preserve their spherical
shape, as they cool, the pins J. are therefore passed vertically into and along the
above described slits or apertures B in the plate A. where they are finally received
and located in the holes C. provided for the purpose, the knobs or heads J¹ being

page_text: supported by the bevilled or sunken edges of same, where they are allowed to
remain until the heads are perfectly cool.
It may be stated that the plate is revolved as may be required so that the pins
may be rapidly passed into the slits, therefore the rounded off corners, leading to
the slits assist this operation by acting as guides to same.
When the heads of the pins are cool and set, by revolving the plate A upon its
spindle in the direction indicated by the arrows the pins are caused to be cast off
by their coming into contact individually with the lever arm H as the plate
revolves by reason of the lever projecting beyond the periphery of the plate and
which thus catches against them and so pushes them in turn out of their individual
slits or apertures B. wherefore the object of cutting these slits in a slanting or curved
form is to allow of the easy displacement of the pins by the action of the lever during
the revolution of the plate.
By these means it will be manifest that the necessity of the removal of the pins
by hand is entirely obviated, moreover the knobs or heads are attached to the
pins and perfectly moulded and much saving of time and labour is effected whereby
they can be manufactured in far less time and of more perfect formation than has
hitherto been practicable by the methods adopted.
It will be clear that the number and size of the slits and their terininal holes
may be regulated according to the required number and size of the pins and
their heads.
When other than spherical knobs or heads are required to be moulded onto the
pins the holes will be formed of the necessary shape to turn out the same.
We do not limit ourselves to the precise formation and arrangement of parts
comprising our improvements as herein more fully set forth as we may modify
the same.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is,
Firstly. The improvements in connection with the manufacture of glass headed
pins and in the means to be employed therefor; as set forth and described.
Secondly. In the manufacture of glass headed pins, a revolving metal disc like
plate, having a series of curved or straight slits or apertures therein at suitable
angles relatively to each other and the spindle centre for the purpose named
said plate revolving horizontally upon a vertical spindle supported on a stand, base,
or table, said spindle having a right angular lever arm projecting therefrom, all
operating for the purpose and in the manner set forth and described.
Dated this 22nd day of January 1896.
