SAFETY-PIN.

Specification of Letters Patent.

Patented Aug. 19, 1919.

Application filed August 19, 1918. Serial No. 250,614.

To all whom it may concern Be it known that T, Jones WEIS, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and useful Improvement in Safety-Pins, of which the following is a specification.

My invention relates to a safety-pin which is easily formed, having a simple construction,'and formed of any suitable material, being adapted for use on a simple safety-pin or pins, brooches or other articles of a similar nature.

The primary object of my device is in a safety-pin with locking means to prevent horizontal movement of the pin arm when the pointed end of the same is held in the sheath or guard and to prevent its accidental opening when in use.

A further object of the invention is in means for locking the pin arm against 1ongitudinal movement in elther direction, to prevent its being drawn out of the sheath which covers the sharp pointed end of the pin arm when the safety-pin is closed. This construction allows considerable strain to be exerted on the pin arm, when the safety-pin is in use, and closed, without any danger of the arm becoming dlsengaged from the protecting sheath.

It is also an object of my safety-pin to form means on the body portion or loop of the safety-pin which is adapted to hold the pin flat with the outer surface of the garment to which it is attached.

In the drawing forming part of this specification Figure l is' a perspective View of my safety-pin as it would appear when attached to a garment, only a portion of the garment being illustrated.

Fig. 2 is a perspective view of the safetypin in open position.

Fig. 3 is a perspectlve view of an alternative form of my safety-pin- Fig. 4 is a cross section on the line 44 of Fig. 3, illustrating a portion of a garment, and in dotted outline the pos1t1on 0f the pin arm when released from the point holding sheath.

Fig. '5 is an end elevation looking at the safety-pin from the sheath end.

Fig. 6 is a cross section on the line 6-6 of Fig. 7 also illustrating in dotted outline a portion of the connecting parts.

"tially rectangular in shape. the wire 2 forms the pin arm 4 which is Fig. 7 is a front elevation of the safetypin illustrating the same in closed position. Figs. 8 and 9 are details of a portion of the safety-pin illustrating an alternative formed with a free end 5, and which is adapted to open or close the loop portion 3, the arm 4 forming one of the longitudinal sides of the loop 2.

I The other end of the wire 2 is bent to form loops or recesses 6 and 7 which are connected by a longitudinally extending shank portion 8, the wire 2 being bent upward from the recess or loop 7 and then curved downward, forming a loop 9 and positioning the end 10 adjacent to the shank 8 and the recess 6.

The loops 6 and 7 with the connecting shank 8 and the loop 9 form a sheath or guard B for the free end 5 of the arm 4 and when it is desired to close the pin A the free end 5 is inserted in the recess or loop 6, pressing the end or catch 10 out of the path of the free end 5, and allowing it to enter the recess 6. The end 10 of the wire 2 will automatically spring back adjacent to the shank 8 and directly above the free end of the arm 4 to engage the same and form a stop or catch to prevent the free end 5 from being accidentally disengaged from the sheath B, the apex ll of the end 5 is adapted to extend a short distance into the recess 7 when the arm 4 is in closed position, and as illustrated in Fig. 6. The recess 7 forms a guard for the sharp point 11 of the free end 5.

A recess 12 is formed on one side of the arm 4 near the point 11, so as to engage the rear side 13 of the recess 6 and the front side 14 of the recess 6, engaging the front surface of the arm 4 to force the recess 12 into engagement with the portion 13, when the arm 4 is inserted or snapped into position in the sheath B, to close the pin A. When the recess 12 is engaged by the portion 13 it is locked to rigidly hold the arm 4 against forward or backward longitudi nal movement, to prevent the free end 5 from becoming disengaged from the sheath B when the pin A is closed, even when a terial, and preventing the pin A from becoming easily disengaged from the garment B when the pm A is open. The pin will lie flush'with the surface of the garment to which it is attachedwhen the folds C are held in the recess 16.

In the construction illustrated in Figs. 3 and 4 the wire 2 is bent so as to form projecting members 17 on either end of the recess portion 16. The members 17 tend 'to 7 form stops which engage the surface of the garment when the folds are held in the recess 16 to revent the easy rotation of the safety-pin K about the recess portion 16, also holding the pin A flat against the garment at all times.

The arm 4 is connected to the portion 15 by a short shank 18 and the pin A is bent so that the free end 5 of the arm 4 will rotate horizontally from the shank 18 when the arm 4 is released from the sheath 3, and as indicated by the arrows in Fig. 2. Thus when the arm 4 is released from the sheath B instead of moving transversely away from the pm A it will move horizontally,

1 rotating with the shank 18 as its axis, as

suming the position illustrated in Fig. 2 and in dotted lines in Fig. 4.

The end 10 forms a catch to hold the free end 5 in the sheath B and the free end 5 can only be released from the sheath B by pressing the end 10 of the loop 9 backward into the position illustrated in dotted outline in Fig. 5, thus moving the end 10 out of the path of the arm 4 and allowing it to be disengaged from the sheath by moving it upward to disengage it from the recess 6.

The arm 4 can be formed with recesses 19 on either side of the same, and the portions 13 and 14 positioned close enough together so as to engage in the recess 19 when the free end 5 of the arm 4 is inserted in the sheath B, as illustrated in Figs. 8 and 9. This alternative construction of the arm 4 illustrates another manner in which the arm 1 4 is locked in the recess 6 to hold itagainst backward by the locking means which is formed .by the recess 12 of the engaging portions 13 and 14, thus holding the arm 4' locked against longitudinal movement in either direction, and allowing the use of a skeleton or open formed sheath, such as B, whichis provided with a'locking means to prevent transverse movement of the pointed end of the arm 4 when it is held in the sheath B. In thisxmanner the'arm 4 of the pin A is held against longitudinal or transverse movement bythe locking means in the sheath B, making it practically impossible to accidentally unlock the same.

The locking means formed in the sheath portion of the safety-pin by the members 13 and 14, together with the notch 12 hold the pin arm 4 against longitudinal movement in either direction, thus preventing thesharp point 11 of the pin arm 4 from moving forward in the recess 7, which would project the same from the sheath B where it might'be apt to stick or injure the user of the safety-pin. The spring arm or end 10 of the loop 9 forms a spring catch to hold the free end 5 of the pin arm 4 from moving in the opposite or transverse direction of the pin, thereby holding the free end of the pin arm securely locked against movement in any direction in the sheath B.' To

release the free end 5 of the arm 4 it is necessary to press the spring catch 10 into open position, as illustrated in dotted lines in Fig. 5, whereupon the free end 5 canbe lifted out of the recess 6, disengaging it y;

tion to the recesses 12 and 19 of the conp structions illustrated. The recess 20 is -firmly engaged by the spring clasp 21 to hold the pin 4 against longitudinal and transverse movement in either direction,

thus making a very desirable construct-ion for a brooch, and preventing the easy bending of the arm, which would cause it to become disengaged from the sheath in the ordinary construction of safety-pins rwhere the pin is not held against longitudinal movement on'its -free pointed end.

In accordance with the patent statutes, I

have described the principles of operation of my invention, together With the apparatus which I now consider to represent the best embodiment thereof, but I desire to have it understood that the construction is only illustrative, and that the invention can be carried out by other means and applied to uses other than those above set forth within the scope of the following claims.
