UNITED STATES PATENT ai men WILLIAM H. FARMER, OF MONTGLAIR, NEW JERSEY, ASSIGNOR TO CONSOLIDATED SAFETY PIN COMPANY, OF BLOOMFIELD, NEW

JERSEY, A CORPORATION OF NEW JERSEY.

SAFETY-PIN.

Application filed May 14,

To all whom it may concern:

Be it known that I, WILLIAM H. FARMER, a citizen of the United States, residingi Montclair, in the State of New Jersey, have invented certain new and useful Im rovements in Safety-Pins, of which the fol owing is a specification, reference being had to the accompanying drawing, forming a part hereof.

This invention relates particularly to safety pins of the duplex type, that is, pins in which the pin point may be engaged with the head or shield from either side, the free passage of the pin point through the head or shield from side to side being prevented or obstructed by a partition. In order that the thickness of the duplex head may not be too great, the partition referred to is commonly formed of a thin piece of metal which is clamped in the shield. The manufacture of such pins, however, is somewhat expensive. It has also been proposed to so extend the end of the pin wire across the opening in the shield as to serve the purposes of a partition, but this has proved unsatisfactory, not only because of the undesirable thickness thereby given to the head, but because the wire, while operating to prevent the passage of the pin point directly through the shield from side to side, has not sufficient width to afford a substantial bearing for the pin point and at the same time sufficiently rotect the actual point of the pin, the resu t being that the threads of delicate fabrics are often times caught upon such unprotected point and occasion difficulty in the removal of the pin or are themselves broken.

It is the object of this invention to so improve the construction of pins of this charac ter as to provide a thin partition, broad enough to afford an ample bearing for the pointmember and to protect the extreme point, without incurring the expense in construction due to the use of a separate piece for the partition.

The invention will be more fully explained hereafter with reference to the accompanying drawing in which Figure 1 is a view in side elevation of a safety pin which embodies the invention. Fig. 2 is a similar view showing the in wire without the shield. Fig. 3 is a detai view in section on the plane indicated by the line Specification of Letters Patent.

8-3 of Fig. 2. Fig. 4 is a detail view in section on the plane indicated by the line 44 of Fi 2. Fig. 5 is a detail view in section on the p ane indicated by the line 55 of Fig. 1.

The pin wire comprises as usual a point member 0, having a sharpened point a, a l spring coil 1) and a back member 0. The head end of the back member is bent, as at d, to

permit the head or shield e to be secured thereto, such head or shield e being formed of thin metal in any usual or desirable shape. The extreme portion of the head end at of the wire is bent sharply over upon itself as at (1 and is flattened to form a thin and broad bearing member or partition 61 which extends from a 1 line closely adjacent to the head end (i back 1 toward the spring coil 1) flat enough to form broad and ample bearing for the pin point a. It is also extended nearly to the back member 0 so as to prevent the passage of the pin point through the shield. By so forming the i partition plate (Z as to extend closely adjacent to the head portion (Z, the actual point i of the pin is completely protected so that it cannot catch. upon even the most delicate i fabric, while at the same time the point member has a bearing which is extended back from the apex far enough to guard against the possible bending of the delicate point of the pin. The thin, wide partition is formed at a single operation, in the manufacture of the pin, which is thus carried on much more economically than is possible when the partition is formed of a separate piece and secured in place.

I claim as my invention:

A safety pin comprising a point member, a back member and a shield, the head end of i the back member being bent to receive the shield and the extremity thereof being bent i over sharply upon itself and flattened, forming a thin, wide partition extending back to- 1 ward the spring end of the pin to afford a broad bearing for the pin point and extending forward closely to the head end of the wire to completely protect the pin point.

This specification signed this 11th day of May A. D., 1908.
