SAFETY-PIN.

SPECIFICATION forming part of Letters Patent 'No. 533,992, dated February 12, 189 5.

Application filed March 19, 1894'.

To aZZ whom it may concern.-

Be it known that I, ELIAS LEwIs, a citizen of the United States, residing at Terre Haute, in the county of Vigo and State of Indiana, have invented certain new and useful Improvements in Safety-Pins; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates. to that class of pins known as toilet or safety pins, and provides one that is at once easy of manufacture, and is positive in its action.

It is well known that the so called safety pins often become loosened and detached for the reason that the pin proper is not sufficiently engaged in the shield to resist certain pressures that occur in ordinary wear. My invention is for the purpose of avoiding these results, and to attain the desired security. I

In carrying out my invention, .1 form a safety pin from an integral piece of wire such as is proper in form and material and in the manner as follows: The pinproperfis sharpened as the description following .will make clear.

I will first minutely describe my invention with relation to the accompanying drawings, and will then define the substance of my invention in the claims.

In each of the figures, the same letter represents uniformly the same part.

Figure 1 represents an elevation of the pin as seen from the side, and shows the pin proper as it appears when fastened. Fig; 2 represents the reverse side of the same pin, said pin havingbeen changed end for end. It happens that this latter view is of that side of the pin, upon which the point enters the shield. Fig. 8 represents a perspective View of the pin showing both the side shown in Fig. 1, and the end portion of the shield.

In this view, the point is shown as entering v the shield.

By referring to the drawings (particularly to Fig.1) it will be easily understood that I make my safety pin in the way following,

tion of the pin itself such as to make it clear and plain to those versed in the art.

One end of the integral wire of which I make my pin is sharpened, this to be the point of the sharpened member a of the pin. The wire is further bent into the resilient coils b which may be of such number as found desirable. It is then carriedin adirection generally parallel to the sharpened member a, forming the bar 0, until at point (1 it makes a right angle turn toward the said sharpened member a and forms shield-bar c with its shoulderfat its upper extremity. Cont-inuing, the wire is bent into a shield-loop 9, passes under said shoulder f and forms a shield-loop 71 parallel to the shield-loop g, and which returns to the right angle turn described as being at d. At this point the wire bends once about the bar-member c, and taking the direction of the shield-bar 6, forms the locking member c', the extremity of which meets and rests firmly against the shield-loop g at a point It in tangent contact. This contact is maintained by the resilience of the locking membert' by reason of the turn about the bar members at point d. V

In its operation, my device works in the following manner The sharpened member a to enter the shield, must press the locking member z from its contact with shield loop g and pass between them (as shown clearly-at Z in Fig. 3), into the said shield, (as shown by dotted lines a, Fig. 3.) The locking member 2' being resilient, returns to its contact with shield loop g, and prevents egress of the sharpened member 0., unless such path of egress be made by repressing the locking member 11 from its tangent contact with shield loop g. p

Having described my invention and its operation, what I desire to secure by Letters Patent is- 1. As a new article of manufacture, a safetypin consisting of a single piece of wire having at one end a shield-aperture formed between the flat shield-loop h and transverse shieldbar 6 upon one side and the shield-loop g and resilient locking-member'i resting tangent to said shield-loop g upon the other side, said resilient locking-member i being formed by carrying shield-100p h downward to the lower part of the pin and so winding the said end
