PROVISIONAL SPECIFICATION.
Improvements in Machines for the Manufacture of Ball Pointed
Hair Pins and similar Artioles.
T
I, CHARLES BEAUMONT of 48 Grande Ruo, Roubaix, in the French Republic,
Engineer, do hereby declare tho nature of this invention to be us follows:-
This invention relates to machines for the manufacture of hair pins and other
articles having "ball" or other similar blunt or compressed points, and consists in
improved means for the production of such points.
"
In the machine to which these improvements relate, the blank or length of
straight wire from which the hair pin or other article is to be produced is held in a
pair of jaws with its ends slightly protruding. The ends are compressed whilst Bo
held by punches or dies, and it is to the means for actuating these punches that
this invention especially relates.
In producing the points, the puuches have to approach each other, and I may
obtain this motion by means of straight or bent levers acting upon the punches,
The fulcra of these levers are between the points where the power is applied and
those where the levers touch the punches. Hence any forces used to separate the
outer points of the levers, will cause the punches to approach and apply pressure
upon the ends of the blank. I may employ, for the purpose" of separating the
outer ends of the levers, a duplex cam, a toggle joint operated by a crank or
excentric or the like device.
The punchesnay work in slides or guides and may be returned by springs.
In some cases, the punches may be connected directly with the ends of a toggle
joint actuated by a crank or excentric and a connecting rod, without the inter-
vention of the levers.

וי
I, CHARLES BEAUMONT of 48'Grande Rue, Roubaix, in the French Republic,
Engineer, do hereby declare the nature of this invention, and in what manner
the same is to be performed; to the particularly described and ascertained in and
by the following statement
This invention relates to machines for the manufacture of hair pins and other
articles having "ball" or other similar blunt or compressed points, and consists in
improved means for the production of such points.
"
In the machine to which these improvements relate; the blank or length of
straight wire from which the hair pin or other article is to be produced, is held in

page_text: a pair of jaws with its ends slightly protruding. The ends are compressed whilst
so held, by punches or dies, and it is to the means for actuating these punches or
dies that this invention relates.
In producing the points, the punches have to approach each other, and I may
obtain this motion by means of straight or bent levers acting upon the punches.
The fulcra of these levers are between the points where the power is applied and
those where the levers touch the punches. Hence, any forces used to separate the
outer points of the levers, will cause the punches to approach and apply pressure
upon the ends of the blank. I may employ for the purpose of separating the outer
ends of the levers, a duplex cam, or a cam for each lever, a toggle joint operated
by a crank or excentric, or the like device.
The punches may work in slides or guides and be returned by springs.
In some cases, the punches may be connected directly with the ends of a toggle
joint actuated by a crank or excentric and a connecting rod, without the inter-
vention of the levers.
I will more particularly describe my said invention with reference to the
accompanying drawings in which
Figures 1 and 2 represent respectively plans of machines having my improve-
ments applied thereto.
Figure 3 shewe, separately, a modified form of a toggle joint arrangement.
Similar letters of reference are used to indicate similar parts where, they occur
in the different figures.
A indicates the fast and loose driving pulleys, B the main shaft, C the feeding
slide, D. the feed cain and lever, E the wire clip actuated by its came the
wire cutter, the wire cutter cam, G the jaws by which the severed wire is
held during the formation of the points, H the cam and rod by means of which
the jaws are reciprocated, and I 1 the punches or dies used in the formation of the
points. All these and other details not represented in the drawings are of the
usual construction.
.
As shewn by Figure 1, the punches II' are reciprocated by the levers KK¹
fulcrumed, at k k¹, and actuated by the cams L L on the driving shaft. These
levers, may be fitted, with the adjusting screws M the points of which bear
against the punches. The return of the punches after the stroke, is effected by
the springs S.
In the arrangement represented by Figure 2, the levers, instead of being
actuated by the cams L L are actuated by the toggle joint Opthe centre of which
is connected by the rod P with the excentric Ron the main shaft. It will be
seen that as the joint is straightened by the rotation of the excentric, the
punches will be forced towards each other.
T
As indicated by Figure 3, the levers may be dispensed with, if the ends of the
toggle joint be connected directly with the outer ends of the punches.
In this case
the arms of the toggle joint are cranked to bring them below the jaws, or similar
means may be employed for the same purpose. The toggle joint is operated as
before by means of connecting rods and an excentric or the like.
เ
Having now particularly described and ascertained the nature of my said inven-
tion and in what, manner the same is to be performed, I declare that what 1
claim is :
"
1 In machines for the manufacture of ball-pointed bair-pins, and similar
articles, straight or bent levers acting directly upon the point, forming punches,
Constructed arranged and operated substantially as herein before described and as
illustrated by the accompanying drawings.
כ:
2. In machines for the manufacture of ball-pointed hair pins, and similar
articles, the combination and arrangement for operating the point forming punches,
of a toggle joint and levers, constructed arranged and operated substantially as
hereinbefore described and as illustrated by the accompanying drawings.

page_text: 3. In machines for the manufacture of ball-pointed hair pins and similar
articles, a toggle joint connected with and actuating the point forming punches,
constructed arranged and operated substantially as hereinbefore described and as
illustrated by the accompanying drawings.
