Improvements in Machinery for the Manufacture of Ball-pointed
Hair Pins and similar articles.
I, WILLIAM EDWIN HEYS of 70 Market Street Manchester in the County of
Lancaster, Patent Agent, do hereby declare the nature of this invention to be as
follows:-
.
This invention relates to machinery employed in the production or manufacture
of hair pins and other similar articles having ball-points.
In the machine constructed for the purpose of this invention, the wire is fed in
lengths each equal to the total length of the blank required for the production of
the article. This may be effected by an adjustable lever horizontally oscillated by
a cam and communicating its motion to a grip carriage which carries the wire in
its forward stroke and releases it when returning. The wire having been fed, is
held and cut. The blank thus formed is then seized at the centre and bent to the
The ends of the
required form, by means of a former and jaws actuated by cams.
pin or other article are then pushed into matrixes in which they are seized, and
whilst so held, the balls or similar points are formed by punches or dies actuated
by a cam and levers and caused to move towards and exert the necessary pressure
upon the protruding points. If the limbs or shanks of the hair pin or other article
have to be "waved" or otherwise shaped, this is done whilst the article is still held
in the matrix.
These various operations having been performed, the moving parts are returned
to their original positions, being aided where necessary by springs. During this
return, the bend of the wire is still held for a time by its former and is thereby
withdrawn from the matrix, after leaving which the article falls into a receptacle
placed below to receive it.

Improvements in Machinery for the Manufacture of Ball-pointed
Hair Pins and similar articles.
I, WILLIAM EDWIN HEYS of 70 Market Street, Manchester, in the County of
Lancaster, Patent Agent, 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 :-
This invention relates to machinery employed in the production or manufacture
of hair pins and other similar articles having ball-points.
In the machine constructed for the purpose of this invention, the wire is fed in
lengths, each of which is equal to the total length of the blank required for the

production of the finished article. The wire having been fed is then held and
cut. The blank thus formed is seized at the centre and bent to the required form.
The ends of the article are then seized and the ball or other similar points are
formed by suitable punches. If the article is to be "waved or otherwise further
bent or shaped, this is accomplished whilst the article is still held for the formation
of the points. The blank having thus been transformed into the completed article
is released and falls into a receptacle below.
The accompanying drawings illustrate the apparatus by means of which this
invention may be carried into effect, and are hereinafter referred to.
Figure 1 is a plan of the machine.
Figure 2 is a longitudinal section.
Figures 3, 4, and 5, represent details of the construction.
Figures 6 and 7 represent respectively an undulated and a plain hair pin with ball
points, such as may be produced by the machine.
A is the framing and B the table of the machine. The wire D is fed by the
lever a, which by its oscillatory motion reciprocates the carrier a¹ in its guiding
channels a. The carrier is adapted to seize and carry the wire in its forward stroke
and to release it when moving back as in other machines of a like character.
lever a is actuated by the cam 1.
The
When the required length of wire has been fed, the lever b descends and holds
the wire, this lever being actuated to operate at the proper time by the cam 2.
Then, the knife c', which slides in the vertical guide W, descends and cuts off the
length of wire. This knife is operated by the cam 3, through the lever c. At the
same instant, the wire blank is seized at the middle of its length by the end of
the piece and the former g, actuated through the slide d by the cam 4. Then the
jaws h, actuated through the slide e and plate e¹ by the cam 5, move forward and
bend the blank to the form of a hair pin, whilst the continued motion of the piece f
finally presents the points of the pin to the matrices p' p' through the perfora-
tions qq of which they pass to such a distance that the points protrude on the
opposite side, see Figures 1, 2, and 5. The perforations of the matrices may be
widened at the entrance to facilitate the entrance of the pin points. The lower
part pl of the matrix is carried upon the vertically reciprocating plate m which is
operated through the lever u by the cam 6. The upper part p. of the matrix is
fixed. As soon as the points have been inserted in the matrices the lower part pl
moves upward and the ends of the pin are thus seized and held whilst the ball
points are formed by the punches, which are further illustrated in, front
elevation by Figure 3. The punches are forced simultaneously against the ends of
the blank to form the points by means of the lever j, the sliding rod i, and the
cam 7. Motion is preferably communicated from the arm j to the punches by
means of the adjustable screws r r in the working direction. The punches lever
and slide rod are respectively returned by the springs y y'.
When it is desired to form an undulation in each limb of the pin, this is effected,
whilst the pin is still held in the matrices by the pressers n n' and the stops tt, the
two pressers simultaneously forcing the parts of the limbs between them between
the stops and thus producing the bend in each limb. The pressers are actuated by
the arms kk' on each of which there is an inclined part. The arın k is moved
by the action of the-rod i on which there is fixed an inclined part k" which comes
into contact with the inclined part of k and thus moves it away from i. On the lever j
there is an extension j having a bevelled end which operates' in contact with the
inclined part of the arm k' and thus moves it simultaneously with the arm k. The
arms k k thus cause the simultaneous approach of the pressers and the amount of
their motion may be regulated by adjusting screws the heads of which form
contacts with the arms. The return of the pressers may be effected by means of
springs as indicated by Figure 1.
..!.
The ball points having been formed, the inatrices open, and the pin is withdrawn
by the return motion of the former g and falls into a receiver, placed below.
The described devices for producing the undulation in the limbs of the pin may

page_text: be considerably modified, if used, according to the result desired. As illustrated,
the stops ttare fixed upon a removable bracket o Figure 4 in the vertical member
of which slots are formed for the passage of the fixing bolts or screws.
More than
two stops, with a corresponding increase in the number of presser points may be
employed if it be desired to produce more than a single undulation.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
1. In a hair-pin making machine, apparatus and devices for simultaneously
producing ball and similar points upon the ends of the bent pin, constructed
arranged and operated substantially as herein before described with reference to the
accompanying drawings.
2. Apparatus for producing ball and other compressed points upon hair-pins and
similar articles, consisting essentially of matrices in which the ends of the pin are
held with the ends projecting, and parallel punches for compressing and forming
the points, constructed arranged and operated substantially as herein before
described and as illustrated by the accompanying drawings.
