SAFETY-PEN.

SPECIFICATION forming part of Letters Patent No. 780,238, dated January 17, 1905.

Application filed March 15, 1904. Serial No. 198,270.

To a, whom it Ina/y concern:

Be it known that I, EDWARD SHEPARD, a eiti- Zen of the United States, residing at White Sulphur Springs, in the county of Meagher and 5 State of Montana, have invented certain new and useful Improvements in Safety-Pins, of which the following is a specification.

This invention aims to provide a novel con struction of safety-pin, the special object in IQ view being to provide an article of this class affording a more rigid securing means as regards substantiality than those now in common use. The invention designs particularly to attain a peculiar locking means for holding I5 the pin in engagement with the catch so as tomake it practically impossible to disengage same under the ordinary conditions of service. For a full description of the invention and the merits thereof and also to acquire a knowl- 2 edge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.

While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is a perspective view showing a pin 3 made in accordance with my invention. Fig. 2 is a side elevation showing the pin engaged with the catch. Fig. 3 is a view similar to Fig. 2, showing more clearly the disposition of the parts when the pin is disengaged from 3 5 the catch. Fig. 4 is a plan view of the invention. Fig. 5 is a longitudinal Vertical sectional view through the invention. Fig. 6 is a horizontal sectional view. 1

Corresponding and like parts are referred 4 to in the following description and indicated in all the views of the drawings by the same reference characters.

The pin when constructed in accord with the principles of my invention comprises three essential parts-namely, a body 1, a shank 2, and a pin element proper, 3. The body may be of any substantial form suitable for the purpose of the invention, and the shank 2 is adapted for a longitudinal or slidable movement upon or in the body, so as to 5 throw the pin 3 into engagement or out of engagement with a catch 4, projected from one end of the body 1. The shank 2 preferably comprises a length of spring-wire bent between its ends to form spaced shank members 5, which maybe passed through openings longitudinally of the body 1 when disposed in position. The openings receiving the shank members 5 constitute guide means for directing the movement of the shank upon or in the body, as will be readily apparent. 1V hen the Wire from which the shank is formed has been bent to provide the members 5, the loop or bent portion of the said wire is disposed approximately beneath the catch or head 4. 5 The shank 2 or the members 5 thereof are coiled, as shown at 6, to form springs, and one of the said members 5 is extended from the spring-coils 6 to form the pin 3. The pin 8 is disposed above the body 1, and the pointed end thereof is adapted to be received by an opening 7 in the catch or head 4. Longitudinal or slidable movement of the shank 2 is adapted to engage or disengage the pin 3 from the catch or head 4.

In order to hold the pin rigidly in engagement with the catch or head 4 to prevent accidental displacement thereof, which is a defeet in the present types of safety-pins, alock or engaging member 8 is utilized. The mem- 8O ber 8 comprises a hook 9 and a finger-piece 10, and this member is secured to the body 1 in any suitable manner, the inner end of the same being preferably rigidly supported within the body 1 at a point between the shank 5 members 5. Thelock memberS projects from the body at a point beneath the head or catch 4, and the hook 9, which is carried by the lock member, is adapted to engage the looped or bent portion of the shank 2. When the hook 9 9 is in engagement with the shank, as aforesaid, it will be noted that the shank is locked from slidablc movement and that the pin 3 is thereby prevented from disengagement with the catch or head 4. The member 8 has a spring action, so as to automatically engage the shank when the pin 3 has been engaged with the catch or head 4, and the linger-piece hook 9 from the shank 2 whenever it is desired to correspondingly disengage the pin 3 from the head or catch 4. When it is necessary to disengage the pin 3, the finger-piece 10 is moved upwardly and the hook 9 is thus disengaged from the shank 2. A longitudinal or slidable movement of the shank 2 efi'ects the disengagement of the pin 3 from the opening 7 in the head or catch 4.

The pin is very simply constructed, and the operation thereof is likewise so'simple that the average person may readily use the pin to advantage. The under side of the body 1 of the article may be slightly notched, as shown at 11, to admit of free spring movement of the lock member 8.

Having thus described the invention, what is claimed as new is 1. In a safetypin, the combination of a body, a catch or head projected from the body, a shank slidably mounted upon the body and bent between its ends to form spaced members, a pin carried by said shank adapted to engage the head or catch, and a lock member carried by the body at a point between the spaced members of the shank aforesaid, said lock member being provided with a hook disposed beneath the head or catch and adapted to engage the bent portion of the shank to fix the position of the pin.

2. In a safety-pin, the combination of a body, ashank com prising spaced members slidably mounted upon the body, said spaced members being provided with spring-coils, a pin extended from the spring-coils of the shank, a head or catch projected from the body and adapted to be engaged by the pin, a lock member comprising a hook for engagement with the shank, and a finger-piece for manipulation of said lock member.

In testimony whereof I afiix my signature in presence of two witnesses.
