V 4 Claims.
This invention relates'broadly to safetypins,
and has among its objects the production of such
pins that will be neat and simple in. construction
and operation, economical to make, and other
5 wise satisfactory and e?icient for use wherever
deemed applicable.

The invention has as its principal object, the
production of a safetypin that will not spring its
point outwardly when accidentally released, but
10 upon the contrary, will tend to remain in closed
position regardless of whether or not the point is
released.

one of the legs, as. for example, the leg I, is re

the usual point 4.

It is to be particularly noted at this time, as it
is one of the principal objects ofv my invention,
that the leg portions are initially sprung together
so that when releasedfthe free ends will be closer
together thanv when in their latched position. I
This is exactly the opposite of the usual safetypin,
for in the latter, the point springs away from the
other or unpointed’free end when unlatched.

A guard or head is mounted at- the free ends of
the'pin member, as at 5, said guard being prefer

parts herein shown and described, and the uses
mentioned, as will be more clearly pointed out in
the claims hereunto appended.
In the drawing, wherein like reference char

throughout the views,

position to be detached from the material to

Figure 3 is a detail view of some of the parts
shown in Fig. 2, illustrating the manner of main

position.
Referring more particularly to the drawing,
wherein I have shown a preferred embodiment of
my invention, there is shown a safetypin made up
50 of two main members, namely the pin member
and the guard member.
The pin member is preferably formed of the
desired length of spring wire, bent to provide a
pair of substantially parallel leg portions I—-2,
55 joined together intermediate the length of the

an obstruction 8 to slightly reduce the width of
the slot passage, preferably by pressing portions
of the guard across said slot. A projection 9 is
formed in any desired manner on the adjacent
end of the pin leg 2, as by pressing or crimping
the material thereof, the width of this projection
and its shape being such that it will resiliently
press back the obstruction 8, as it is snapped

longitudinal movement, and ride easily in the
normal parts of the opening. Obviously, when
the projection is on the left of the obstruction, 45
as shown, the point 4 will be furthermost within
the guard and accidental release is substantially

When the guard is shifted to the left, so that
the projection 9 is to the right of the obstruc

point may be forced away from the guard to re
lease it from the fabric to which it is pinned. .
Whether accidentally or purposely spread, the
point will be retrieved to its normal position to 55

holding it outwardly is relieved.
Having thus described my invention, it is obvi
ous that various immaterial modi?cations may
be made in the same without departing from the
spirit of my invention; hence I do not wish to be
understood as limiting myself to the exact form,
arrangement, construction and combination of
parts herein shown and described, except as lim
10 ited by the state of the art to which this inven
tion appe'rtains, and the claims hereunto ap
