Improvements in Safety Pins.
I, JOHN MURRAY GUILBERT, of 223 N. 5th Street, Philadelphia, Pennsylvania,
United States of America, 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 :-
My invention consists of a guide and guard for a safety pin, the same being:
adapted to direct the point or point portion of the pin to its seat and then prevent:
its displacement therefrom, as will be hereinafter set forth.
Figure 1 represents a side elevation of a safety pin embodying my invention.
Figure 2 represents a perspective view thereof.
Figure 3 represents a face view of the guide and guard in its primary condition..
Figure 4 represents a perspective view of the guide and guard prior to attachment
to the pin.
Figure 5 represents a section on line x, x, Figure 1.
Figure 6 represents a side elevation of a safety pin without the guide and
guard.
Similar letters of reference indicate corresponding parts in the several figures.
Referring to the drawings:
A designates a safety pin formed of bar and pin members, which, excepting the
feature of my invention applied thereto, are of well known form and construction.
B designates a guiding and guarding yoke, formed of a piece C of metal or other
material, with the V-shaped recess D in its upper edge of the neck D', and the
lip E depending from near one end, said piece C being bent on said neck, producing
the shape substantially as shown in Figure 4.
The yoke B is applied to the end of the bar member or limb of the pin
containing the seat F for the point of the pin, the side pieces of the yoke inclosing
the sides of said seat, and being separated therefrom a sufficient distance to permit
the entrance of the point portion of the pin proper to pass between said seat and
either side of the yoke, as most clearly shown in Figure 5.
The lip E is connected with the ridge G of the limb of the pin, and thus the
yoke is firmly connected with said limb, it being noticed that the recess D is on
the inner end of the device.
The operation is as follows:
When the pin is to be closed and fastened, the point portion of the same is
passed between the seat F and either side of the yoke, and pressed down until
it strikes the base of the recess D, when it is let go, and then springs outwardly
or back, whereby it enters the seat F and is held therein, it being noticed that
the base of the recess is directly in line with the opening in the seat, so that
the point portion readily moves from said base into said opening.
It will also be noticed that the sides of the yoke extend outwardly beyond
the inner walls of the opening in the seat, as seen in Figure 5, and thus guard
said opening, so that should the point portion be pressed inwardly, so as to clear
the walls of the seat, the sides of the yoke serve as deflectors and while they
resist the lateral motion of the point portion, they direct said portion back to
the seat, whereby disconnection of the pin portion from the same is prevented.
When however the point portion is pressed in to full extent and contacts with
the base of the seat, said portion may be moved laterally to such distance that
it may be guided to the space between the seat and either side of the yoke, and

page_text: then directed outwardly through said space, whereby the point portion is dis-
engaged from the seat and the pin accordingly opened.
The lip E may loosely embrace the limb of the pin, so as to be permitted to
oscillate thereon, whereby the sides of the yoke or saddle may move to and from
the sides of the seat. When the pin is passing through the space at one side of
the seat, that on the other side is closed. By this provision the saddle may be
made of less width than.when it is stationary or immovable.
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 :-
1st. A safety pin provided with a seat in the bar member thereof, and a guide
and guard on opposite sides of said seat, said guide and guard being formed of a
yoke having a recess in the upper edge of the neck thereof, and means for
attaching said yoke to said member, substantially as described.
2nd. A safety pin provided with a seat, on the bar member thereof, for the
point of the pin member, and a guide and guard for said point consisting of a yoke
on opposite sides of said seat, formed with a recess in the edge of the neck of said
yoke, and a lip projecting from said yoke connected with the bar member opposite
to said seat, substantially as described.
3rd. A safety pin provided with a seat for the point of the pin member thereof,
and a guide and guard for said point, consisting of a yoke formed with a recess in
the edge of the neck of said yoke, and means for fastening the yoke to the bar
member opposite to said seat, substantially as described.
4th. A guard and guide for a safety pin, consisting of a bent piece of metal
having a recess in one edge of the bend and a lip on one limb of said piece,
substantially as and for the purpose set forth.
