SAFETY-PIN.

Specification of Letters Patent.

Patented Jan. 21, 1908.

To all whom it may concern:

i -FBe it known that we, HENRY KASPAR and J OSEPI-I KREJOI, citizens of the United States, residing at Tyndall, in the county of Bonhomme and State of South Dakota, have invented a new and useful Safety-Pin, of which the following is a specification.

This invention relates to safety pins and has for its object to provide a comparatively simple and inexpensive device of this character in which the point of the piercing mem her is effectually housed and locked against accidental displacement.

A further object of the invention is to provide a guard one end of which is rigidly secured to the stationary member of the pin while the opposite end thereof is bent to form an overhanging retaining hook or keeper for the reception of the piercing point, the walls of the guard at said hook being deflected laterally to form a guide for the point of the piercing member.

A further object ,is to provide a guard one wall of which is inclined or beveled in the direction of the hook or keeper thereby to assist in guiding the piercing point in engagement therewith, and further to provide a depending spring locking tonguefor locking the piercing member against accidental displace.

ment.

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

g In the accompanying drawings forming a part of this specification: Figure 1 is a perspective view of safety pin constructed in accordance with my invention. 'Fig. 2 is a transverse sectional view of the same. Fig. 3 is a perspective view of the spring locking member or tongue detached. Fig. 4 is a transverse sectional view illustrating a modified form of spring locking tongue. Fig. 5 is a perspective view of a further modification. Fig. 6 is a transverse sectional view of the pin shown in Fig. 5. Fig. 7, is a perspective view of a modified form of guard. Fig. 8 is a similar view illustrating a still further modification, and Fig. 9 is a transverse sectional view of the pin shown in Fig. 8.

corresponding parts in all of the figures of the drawings.

The body portion of the safety pin forming the subject matter of the present invention is preferably formed of a single piece of wire or similar material having its intermediate portion bent to form a spring coil 5 and its opposite end extended laterally to form relatively stationary and movable members 6 and 7 one of which is provided with a piercing point 8.

Rigidly secured to the free end of the relatively stationary member 6 'is a guard or shield 9 having its marginal edge on one side thereof bent to forma tubular socket 10 for the reception of the stationary member 6,

the opposite edge of the metal forming the wshield 9 being bent upwardly and spaced from the intermediate imperforate portion of the shield to form aninclined flange 11.

One end of the flange 11 is bent inwardly and downwardly to form an over-hanging hook or keeper 12 adapted to receive the piercing point of the member 7, the metal at said hook being deflected laterally to form an inclined face 13 which serves to assist in guiding the piercing point 8 to its seat in engagement with the keeper.

As a means for locking the piercing point against accidental displacement there is provided a sprin locking member preferably in the form 9 a plate one end of which is provided with a spring tongue 14 which normally bears against the adjacent edge of the hook or keeper 12 while the opposite end thereof is provided with a segmental extension 15 which bears against the shield 9 and is locked in position on the shield by engagement with the tube or socket 10 and the marginal flange 11. The upper longitudinal edge of the locking member is curved laterally to form a supporting hook 16 which is interposed between the stationary member and the socket 10 and is locked in engagement with the stationary member by contact with the metal forming the socket. The

lower wall of the guard or shield 9 is inclined or beveled in the direction of the hook or 'kee er 12, as indicated at 17 so asto assist in gui ing the piercing point 8 to its seat in engagement with said keeper. The intermediate portion 18 of the spring tongue 14 is preferably deflected laterally at an angle adjacent wall of the guard or shield and permitting the point of the piercing member to come in contact with the inclined wall 17 of the guard, when the tension of the spring 14 will force the point of the piercing member down the inclined wall of the guard into engagement with the base of the hook and thus effectually lock the piercing point tongue. clined'face '13 of the guard isdispensed with,

against accidental displacement,

In order to release the piercing memberit is merely necessary to press laterally on the spring locking tongue which releases the piercing point and thus permits thesame to be readily disengaged from said hook.

In Fig. 40f the drawingthere isillustrated a-modified form of spring locking tongue in which the segmental extension 15 of the plate is bent laterally whilethe spring lock 7 ing tongue 14 is disposed in a substantially vertical plane.

In 'Figs.5 and 6 of thedrawingsthere is illustrated a further modification in which the spring locking tongue is 'dis ensed with, the :hook-or keeper '12being re ied upon 'to' prevent accidental'displacement ofthe piercing point.

In Fig. 7 the metal forming the guard .or

shieldis cut or slit at 19t0 facilitate bending the metal to form "the inclinedface 13, the

locking tongue or spring being also dispensed with in this case.

In Figs. 8 and 9 of thedrawings the piercing member 7" is preferably offset with respect to the hook or'keeper 12 so that the spring tension of 'thepiercing member will lock the same against accidental displacement without the employment of the spring In "this form of the device the-inthe edge of th'e'metal forming the shield being bent inwardly and downwardly to roduce thelocking hook or keeper 12.

The pins may be'm'ade in different shapes and sizes and nickeled, plated or otherwise coated to give the same a neat attractive appearance.

From the foregoing description it will be seen that there is provided an extremely simple, inexpensive and efficient device admirably adapted for the attainment of the ends in view.
