PROVISIONAL SPECIFICATION.
Improvements in Safety, Nursery, and other like Pins, Curtain
Hooks, and other Articles of a like Manufacture.
I, OLIVER GRIFFITHS GOODMAN, of 82 Caroline Street, in the City of
Birmingham, Manufacturer do hereby declare the nature of this invention to be
as follows:-
This invention relates to the loop-coiled end or ends of safety or nursery pins
and other articles of a like manufacture, such as the pins of curtain hooks, the
pins of apron fasteners, garment holders, bouquet holders and the like.
These safety pins and the like have the tongue part inwardly terminated by a
double loop coil, which springs or opens out the said tongue, when released from a
catch or like fastener. The coils of the spring loops lie close one upon another,
but oftentimes leave a slight intervening space between the said coils, so that frayed
parts of a garment or fabric are apt to be caught between the said coils when
opened out.
.
Thus, when the coils are contracted or expanded consequent upon the closing or
opening of the tongue, the coils have a tendency to open and close, and pinch and
hold the fabric or frays of a garment between them.
The object of my invention is to fill up the interstice between the coils, thereby
preventing the pinching or laying hold of the fabric by the coiled ends.
Usually, such coils are shielded by sheet metal caps, closed over the outside
parts, but leaving the limbs clear and free.
According to my invention, I fill up the interstice or interstices with metal as
near as possible alike unto the metal composing the article.
In carrying out my invention, I dip or immerse the coiled ends, or those parts
of the coiled ends presented outermost, into a soldering liquid, consisting of a
solution of zinc in hydrochloric acid, when. the said solution prepares the metal
part or parts comprehending the interstice or interstices; then I dip the said end
into a bath of molten solder or like metal or alloy, when the said divisional space,
interstice or interstices are filled up flush to the outer circumferences of the coils,
by the soldering or other metal, hence the uniting of the coils, or the formation of
a solid end or part end, which may be subsequently polished or finished in any
desired way.
Dated this 8th day of December 1892.

COMPLETE SPECIFICATION.
Improvements in Safety, Nursery, and other like Pins, Curtain
Hooks, and other Articles of a like Manufacture.
I, OLIVER GRIFFITHS GOODMAN, of 82, Caroline Street, in the City of
Birmingham, Manufacturer, 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 the spring coils or to the loop coiled end parts of safety
pins and other articles of a like manufacture, such for example as nursery pins,
curtain hooks, apron fasteners, garment holders, bouquet attachments and the like.
Now the separate loops composing these spring coils open out when the article

page_text: is unfastened, and close when fastened, so that normally the loops of the spring
coils are slightly separated by intervening spaces, into which the loose fibres or
frayings of a garment are apt to get, and be there caught by being pinched
between the opposed faces of the coils when the article is again closed.
This laying hold of the frays or fibres of a garment is a considerable draw-back
in the use of such articles, and particularly in the case of young children where
fluffy clothing is so often worn.
The object of my invention is to obviate this defect in such articles, and this I
accomplish by filling up the interstice or interstices between the spring coils with
metal, alloy or composition, so as to make the said spring coils practically solid
without interfering with their resiliency and action.
In carrying out my invention in connection with a safety pin, I first dip or
immerse the coiled ends or the outer parts of the coiled ends into a cleaning or
oxide-removing liquid, such as a solution of zinc in hydrochloric acid. Then I
again dip the said coils or parts of the coils thus treated into a bath of molten
solder, metal alloy or metal, when the interstices or divisional spaces between the
loops of the spring coils are filled up, thus making the said coiled ends or the parts
of the said coiled ends practically solid, and without intervening spaces or crevices
into which the fibres or frayings of garments might be liable to be caught.
Instead of employing a solution of zinc in hydrochloric acid, I may employ any
other well known solution, or I may employ resin or the like..
Figure 1 of the accompanying drawings is a side elevation, and Figure 2 is a
section of a nursery pin with the interstices between the loops of the spring coiled
end a filled up and the same united by a filling-up metal b.
Figure 3 is an end elevation of the coils of the pin before the interstices between
the same are filled up and united as aforesaid.
Figure 4 is an end elevation of the coils Figures 1 and 2, and Figure 5 is a
cross section of the said coil upon an enlarged scale and upon the dotted lines A B
Figure 2.
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 I
claim is :-
In safety and like pins or articles having coiled ends or parts, filling up the
interstices between the loops of the spring coils of the same or a part of the same,
with metal, alloy or composition, whereby the same is made solid or without
interstices intervening between the loops of the coils, and the catching of fibres or
frays of fluffy fabrics prevented, substantially as described and set forth.
Dated this 27th day of August 1893.
