GEORGE W. DOVER, OF ORANSTON, RHODE ISLAND.

SCARF-PIN.

SPECIFICATION forming part of Letters Patent No. 755,856, dated March 29, 1904.

Application filed December 9, 1903. Serial No. 184,387. (No model.)

To all whmn it may concern:

Be it known that I, GEORGE W. DOVER, a citizen of the United States, residing at Oranston, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Scarf-Pins, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to scarf and analogous pins primarily designed to prevent accidental displacement by means of a projection upon the pin-stem, and has for its main object neatness and security of the joining means of the pin parts without the use of solder.

I have in a prior patentapplication, Serial No. 17 5,064, set forth a solderless structure directed-to the above ends which is advantageous for use in plated jewelry, but which is inappropriate for a solid-gold or high grade of goods, besides being weaker and more expensive than my present invention, which is fully described hereinafter in conjunction with the accompanying drawings, wherein- Figures 1, 2, and 3 show the original pinstem blank in its successive stages of completion; Fig. 4:, a side elevation of the complete scarf-pin, and Fig. 5 a section of the latter on line 5 5 of Fig. 4:-

Like reference-letters indicate like parts throughout the views.

My novel structure is formed as follows: The stem is constructed from a blank whose original form is shown in Fig. 1, comprising the longer and shorter cylindrical sections a and b, respectively, intermediate which are oppositely-directed lateral ears 0, lying in the same place as the sections. The thickness of the cars is equal or greater than the diameter of the sections a Z). Each ear has perforations (Z at a like distance from their respective margins. The ears 0 are next bent into planes parallel with each other, as shown in Fig. 2, whereby the perforations or openings d are brought into alinement with each other. The sections a and b of the blank are next swaged into pointed cylindrical pin members, the section Z2 being inclined rearwardly to form a spur upon the upper extremity of the pin-stem.

It should be observed that in bending the ears, as above described, it is desirable that the bending-points 6 should be slightly distant from the stem portion on either side thereof,

as shown in Fig. 5, by this means insuring a flat surface 1; upon the inner or lower portion of the rectangular socket formed by the bent ears.

The head member f of the scarf-pin is provided on its rear face with a rectangular lug g, adapted to snugly fit in the socket formed by the bent ears 0 and whose outer face contacts at every point with the flat surface 6. The lug g is traversed by an opening in alinement with the perforations cl in the ears 0. Through these three openings is riveted, upset, or frictionally held a dowel-pin m.

By the structure above described the head is immovably secured to the pin without solder and in a more secure manner than heretofore employed, and the thickness of the stock comprising the ears obviates the structural weakness prevailingin prior devices of thisnature.

Having described my invention, what I claim 1. In a scarf-pin the combination with a pinstem provided with upturned lateral ears, of a head, a lug upon the head provided with a flat extremity resting against the base of the cup formed by the upturned ears, and means for securing rigidly the lug and ears together.

2. In a scarf-pin the combination with a pinstem provided with upturned lateral ears, of a head, a lug upon the head provided with a flat extremity permanently resting against the base of the cup formed by. the upturned ears, and a securing-pin traversing the lug and ears.

3. In a scarf-pin the combination witha pinstem provided with upturned ears of a thickness approximately the diameter of the pinstem, of a head, 'a lug upon the head resting fixedly against the base of the cup formed by the upturned ears, and means for securing the lug and ears.

I. In a scarf-pin,the combination with a pinstem provided with upturned lateral ears, of a head, a lug upon the head contacting with the base of a cup formed by the upturned ears, and means for rigidly securing the lug and ears together.

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

, GEORGE W. DOVER.
