' Application filed my 17, 1925. Serial No. 44,271.

This invention relates to safetypins and more. particularly to a novel'and' improved means for'locking the pointed or movable member in the hood or shield so as to prevent piercing the surrounding area 'which may occur when the pin is accidentally opened.

One of the objects of my invention is to provide a safety pin wherein the back or fixed member is provided with a slidable latch or look, adapted to cooperate. with the hood or shield of the safety pin so as to prevent the pointed or movable member of the pin from becoming disengaged from the said hood or shield and opened.

To enable others skilled in the art to fully comprehend the underlying features of my invention that they may embody the same in the various alterations in structure and relation contemplated, drawings depicting a preferred form have been annexed as a part of this disclosure and in such drawings, similar reference characters denote corresponding parts throughout all the views, of which,

Figure 1 is a side View of the safety pin showing the same when closed and the pointed or movable member locked.

Figure 2 is a similar view, showing the ointed or movable member open and the ock or latch disengaged from the hood or shield.

Figure 3 is a sectional view, taken on the line 3-3 of Figure 1.

Figure 1 is a sectional view taken on the line 44 of Figure 1.

Figure 5 is a sectional view taken subfixed member is provided with the usual type of head 8 and hood or shield 9, adapted to receive the pointed end of the movable member above referred to.

My invention proper consists of a slidable lock or catch formed from a single blank and having slats 10, 11, formed integral with a sleeve 12, whereby the lock or catch or fixed member.

may slide on the upper portion of theback The said wings are preferably riveted as at 13, thefront edges of said Wings being bent outwardly or slightly flared as indicated at 14 so as to engage the edge of the movable member 6 when in its locked position. The top of the lock or latch is also open so as to bridge the hood or shield, in which position it also engages the pointed or movable member and prevents its separation when looked as shown by Figure 1 of the drawings. In order to prevent the lock or latch from moving toward the coiled spring, the back or fixed member is preferably flattened slightly, as indicated at 16, thus producing a stop so as to limit the movement thereof. The lock or latch is loosely mounted on the back or fixed member 5 and it will thus be seen that it may rotate relative to the back or fixed member when in its disengaged position so that the said lock or latch will not interfere with the movement of the pointed or movable member when it is being directed into the hood or shield.

It will readily be seen that the lock or latch is in engagement with the hood or shield as well as with the pointed or movable member and that the latter cannot be moved either to the left or right to be disengaged from the hood or shield and in which position it securely retains the movable member in its properly locked position.

While I have illustrated and described my invention with some degree of particularity,

.I realize that in practice, various alterations therein may be made. I therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of the correlated parts without departing from the spirit of the invention or the scope of the appended claims. 1

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is 1. A safety pin having a latch or look comprising a pair of connected wings movable along the back of the said pin and adapted to interlock with the safety pin sheath and engage the pointed end of said pin when in said sheath, and means formed in the back of said pin for limiting the movement of said pin lock.

2. A safety pin having a latch or look comprising two connected resilient wings formed from a single blank and movable along the. back of the said pin, said wings being spaced to yieldably interlock with the safety pin sheath and engage the pointed end of said pin when in said sheath.

3. A safety pin having a latch or, look comprising two connected wings formed from a single blank and movable along the back of the said pin, a stop for said latch or lock, said wings being spaced to interlock with the safety pin sheath, the front edges of said wings being slightly flared to engage the pointed end of said pin when in said sheath.

4. A safety pin having a latch or lock comprising two similarly shaped wings formed from a single blank and riveted together for movement on the back of said pin, a stop for said latch or lock, said wings being spaced to interlock with the safety pin sheath, the front edges of the wings being bent outwardly to engage the pointed end of said pin when held in the said sheath.

In testimony whereof I affix my signature.

JOSEPH J KRAMER.
