To all whom, z'zf may concern.'

Be it known that I, KAKUJI,TAKAHasHn a subject of the Emperor of Japan, residing at San lfrancisco, in the county oi San Francisco and State of California, have invented new and useful Improvements in Fasteners Afor Brooches and the Lilie, of which the following is a specification. h

The' present invention relates to improvements in fasteners for securing brooches, badges, and the like, or for attaching watches on the outside of ladies dresses.

It is a common practice for ladies to secure their watches by' means of a pin or fastener pinned to the outside of the dress, and the common construction ot' such tas# tener has been to provide a rotary retainer for the pointed end of the pin, which retainer in one position allows said pointed end to enter therein, while in another position it prevents its escape therefrom. It is found in practice that this retainer is liable to turn accidentally in its bearing, so that it moves into the position in which the pin is released, thereby greatly diminishing the eiicienoy of the fastener. A further objection to the present construction of such'fasteners is that Jthe point 'ofthe pin, projecting through the retainer, is apt to enter the fabric of the dress. When the wearer unloosens the fastener, she does so bybringing the pointed end of the pin to the front to enable the retainer i be more easily turned With the finger. ut if the pointed end of the pin has entered the fabric and engaged one or two of the'threads thereof, this pointed end, forward is to pull' out of the fabricthe threads so engaged by said pointed end, thus greatlyJ damaging the fabric.

The object et my' present invention is to avoid the above detects.

In the accompanying dfawing, Fig-ure l is an enlarged bottom plan view of the fastener; Fig. 2 is a side view thereof, partly in longitudinal secvfon; Fig. 3 is a greatly -enlarged bottom plan vicw of the retaining means, the bearing therefor being shown in section; Fig. 4 is a cross-sectional view thereof on the line 4 4 of F ig. 3; Fig. 5 is an end view thereof in the closed position;

6 is a diagrammatic sectional view.

Reteiqriilig to the drawing, l indicates the a. rasteer, to whi secured a sins' avins' 1oivot upon which a 7 c: l 7

is pivoted the flattened enlarged terminal portion of a pin 4. I

5 indicates a Hat spring, of which one terminal portion is soldered or otherwise suitably secured, as shown lat 6, to the body l 1 of the pin, and the other end bears against a flattened part 7 of the edge of said cnlarged terminal portion, so that the pressure of the spring tends to turn the pin on its pivot into the position shown in Fig. 2. VThe outward movement of the pin is, however limited by the abutment of a portion 8 of the casing against the back of the pin.

9 indicates a c vlimlrical bearing attached, as shown at 10, to the body l of the fastener. .Vithiirthe cylindrical inner surface of said bearing can rotate a cylindrical retainer ll,

and having formed integral therewith at the inner end a flange 12, which abats against the end of the bearing, and at' the outer end an arm 13 by which the retainer can be Vturned in the bearing. The outer end or' said retainer' is closed, as shown at 14, but the inner end is open. There is also formed in the cylindrical body of the retainer a longitudinal opening 15 adapted, by the rotation of the retainer, to be alined with a similar opening i6 in the bearing, both of these openings being suiiiciently large to permit the pointed terminal portion of the pin to be passed therethrough into the interior of the retainer.

The recess to receive the pin within the retainer is formed with parallel Walls and semi-cylindrical bottom, the axis of which is eccentric yto the retainer, so that the pin received within the retainer, is, When the retainer is in its closed position, on the side of said aXis opposite to the body of the fastener. nthis position the spring pressure prevents'the retainer from turning,"notv only by creating trictional resistance between the pin and the retainer and also between the retainer and the bearing, but also positively, for it will be seen that, -when the retainer is turned from this closed position, the pointed endet the pin is thereby pushed inward toward tliediody of the fastener against the spring pressure. Consequently the spring pressure resists this rotary moven'ient'i- Hence the retainer is held very se- `curely against rotation, thereby very greatly` increasing the security afforded by thev l fastener.

extending at each ond beyond the bearing It may be noted that' with the above construction of retainer, the spring could be omitted, and the same general result obtained by the mere outward pressure von the pin of the fabric to which the fastener is secured.

A further important improvement resides in making the retainer closed at the outer end. ,Vhen fasteners of this general character are used to secure watches, or other A articles on the outside of ladies7 dresses, if

the outer end of the retainer is open, it frequently happens that the pointed end of the pin penetrates the fabric of the dress. Vhen this is the case, since the fastener is loosened by moving` the retainer end ofthe fastening forward, so as to permit of manipulation of lthe retainer by theingrers,y this forward movement causes the pointed end of the pin to pull out the threads behind which it has penetrated into the fabric, thereby damaging the dress. In my present improvement this result cannot occur.

I clairnz- In a fastener, the combination with a body, and a pin pivoted thereto, a bearing secured to Said body, a cylindrical retainer for the free end ofthe pin rotatable in said bearing, said bearing having a -longitudinal o )enino to ermit the free end of the in to,

l b p p pass therethrough and the retainer having a recess to receive said free end, the opening into said recess being adapted to register with the openingr in the bearing, said recess` In testimony whereof I have hereunto stit 'my hand in the presence of two subscribing Witnesses.
