Improvements in Safety Pins.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents.
45, Southampton Buildings, in the County of Middlesex, 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 safety pins and the object thereof is to provide a
guard for bridging over the space between the pointed leg of the pin and the coil
which may be applied to the coil end of the pin without threading the guard over
the pointed leg, and which when in position will closely conform to the shape of
the pin. To this end the invention consists of a guard having a hole in the crown
and a lateral passage connecting with said hole through which passage the pointed
leg of the pin may pass into the hole when applying the guard to the pin.
In the accompanying drawings,
Fig. 1 is a side elevation of a safety pin embodying the invention.
Fig. 2 is a side view of a guard before it is applied to the coil of the pin.
Fig. 3 is a view showing the crown of the guard.
Fig. 4 is a plan view of Fig. 1, and
Fig. 5 is a section through the coil of Fig. 1.
The safety pin A is composed as usual of two legs a, b with the intermediate
portion c coiled to form a spring, the leg a being the free or pin portion, while
to the other leg 6 is secured a shield B as usual. In pins of this form there is
liability of the fabric working between or becoming entangled in the coils of the
spring, and a guard d is therefore applied to the coil c which bridges over the
space between the leg a and the coil, and prevents the entrance of the fabric.
This guard consists of a cup-shaped cap provided with a crown portion e and sides f
and g. A hole h is formed in the crown through which the leg a extends and the
sides of the cap are bent to embrace the coil c on both sides of the leg a and thus
bridge over the space between the leg and coil. In order that the cap may be
conveniently applied to the coil while the pin is closed, as in Fig. 1, a passage i
is formed in the side of which connects with the hole h. This passage divides the
side into two lips j and k. In applying the cap to the pin the leg a is passed
laterally through the lateral passage into the hole h and the cap turned slightly
to bring the crown into engagement with the coil c. The lips and k and the
side g are bent to bring their edges inside the coil, the lip embracing the leg
and bridging over the space between the leg and coil, and the lip k embracing
the coil inside the leg a.
a
With this construction of guard the pins may be more conveniently handled,
and the guards more conveniently applied than in cases where the guard must be
threaded over the point of the pin, since with the latter form of guards the pins
must be handled in an open condition or be opened before the guard is applied.

page_text: Moreover with the form of guard described the sides of the guard conform closely
to the wires of the coil and do not detract from the neat appearance of the pin.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, as communicated to
me by my foreign correspondents, I declare that what I claim is:
-
1-A coil guard for a safety pin having a crown, a hole in the crown for the
pointed leg of the pin, and a lateral passage connecting with said hole and thereby
forming two lips on one side of said guard.
2-A safety pin having a coiled portion, a guard applied to said coiled portion,
and having a lip embracing the pointed leg of the pin, and a second lip embracing
the coil inside the pointed leg.
