SAFETY-PIN.

SPECIFICATION forming part of Letters Patent No. 770,304, dated September 20, 1904.

Application filed March 4, 1903.

To all whom it may concern:

Be it known that I, HENRY A. NORTON, a citizen of the United States, residing at VVashington, in the District of Columbia, have invented new and useful Improvements in Safety-Pins, of which the following is a specification.

This invention relates to safety-pins; and the purpose of the same is to provide a novel form of shield for the pin and to dispense with coils to give the said pin a spring action, thereby economizing the cost of manufacture of the device as an entirety and at the same time producing a strong and durable device of this class.

The invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of a device embodying the features of the invention and showing the pin open in clotted lines. Fig. 2 is a bottom plan View of the device. Fig. 3 is a side elevation of a slightlymodified form. of the device.

Similar numerals of reference are employed to indicate corresponding parts in the several views.

In the present form of pin the usual springcoil is dispensed with and replaced by a single bend 1 between the back bar 2 and pin 3, the extremity of the back bar opposite that continuing from the bend 1 being formed with a bend t. The bend t is merged into or attached to a shield,which differs in construction in the several forms of pins. The pin 3 is given a resilient or spring action to cause it to fly outwardly when released from the shield by an inward bend 5 adjacent to the bend 1, this bend 5 being common to all forms shown, and in addition the pin shown by Fig. 3 has a supplementary bend 6 opposite the bend 5 and a similar bend 7 adjacent to the bend 4, thus giving the bends 1 and 4: a substantial circular contour. The bend 5, however, is the most essential feature of construction relative to the spring control and operation of the pin 3 and replaces the usual form Serial No. 146,149. (No model.)

of coil and renders the pin effective in an automatic outthrow or movement when released and also a tight engagement between the point of the bar 3 and the shield when said bar is closed.

The improved form of shield consists of an elongated spiral 8, which is continuous with the wire forming the bend L and opens or has the terminal thereof disposed in such position that the point of the bar 8 may be readily engaged therewith or withdrawn therefrom in the operations of closing and opening the pin. In detaching the pin from the elongated open spiral 8 said pin is drawn longitudinally and sprung laterally, and in securing this pin to the spiral shield a reverse operation ensues, or the pin is-first pushed laterally in one direction against the spiral and then in an opposite direction to set up a connection between the pin and shield which will resist accidental disengagement.

It will be understood that the body of the pin will be constructed of spring-wire of suitable gage and tempered sufficiently to prevent bending or misshaping the parts 2 and 3 by use.

The improved pin in its different forms is applied as ordinary devices of this class, and it will be seen that the elongated spiral shield 8 will firmly hold the point of the pin against accidentaldisengagement, and in all the forms of the device shown as soon as the pin is released it will be thrown outwardly away from the shield through the use of the bend 5.

Less material is required to make the improved device, owing to the absence of the usual spring-coil, and time and labor are saved in securing the ordinary sheet-metal shield in place by continuing thewire into an elongated spiral to provide a shield 8.

It is proposed to ornament the device by plating the same, and such metal will be used in constructing the device as is best adapted for the purpose.

Having thus fully described the invention, what is claimed as new is A safety-pin having a back bar shaped at its opposite terminals to form single bends, from when pressure is applied to the pin and one of the said bends being continued into a body members.
