I?) all whom it m'ayconcem:

Be it known that 1, DAVID M. WATKINS,

" a-citizen of the United States, residing at Proyidence, in the county of Providence and State of Rhode Island, have invented certain .new and useful Improvements in Hat-Pin Protectors, of which the following is a specification,; reference being had therein-to the accompanying drawing.

and my improved pin-point protector at the opposite end. 2is a view in elevation (on anenlarged scale) of said pin-point protector. Fig. 3 is a view on a much enlarged scale .of the pointed end of a hat-pin, a tubular case containing a'spiral spring, adapted to engage said pin and a tubularguide for the insertion of the pin.

My invention relates to the class of hatpins, and consists of-a protector intdwhich the point of the pin is inserted and there partially held in, position.

In the drawings is shown a hat-pin' A of any preferred style. The pin A has the usual point (1 end a. At one end of the pin-A is.v moun ed an ornamental-knob B, ofanyde sign or pattern desired. A cylindrical. or-

other guide C has a tubular bore, whose diameter approximately equals the diameter of the pin A, so that the pin may be loosely inserted' therethrough. The upper portion of the bore is outwardly flared, as illustrated at b in Fig. 3. The guide C is circumfer entially grooved, as shown at o. A tubular case or sheath 1) has its upper end bent inwardly, as seen at=ZZ,'and is swaged to extend 1 into the groove 0 of the guide C, and thus to 40 be secured to said guide. A close spiral spring E is-supported in the case D and one end 0' thereof bears against the inner end of the guide C, as .representecLin Fig. The outer end of the case D is bent inwardly. as

seen at d,-and supports the outer end e of the spring E. A projection F is fastened upon the inner surface ofthe case Dand extends between two adjacent coils of the spiral spring E.

' The inner diameter of the spiral hpring E is approximately the same as that of the pin A, so as to allow the insertion of the pin therethrough with atiglit fit,, and thus to have a slight. resilient contact with the pin to hold it-in place in the spring, except when withdrawnfby a slight force suiiicient to overcome such resilient contact.v lVhen the pin has'been thrust through hat, as usual, my protector (separately shown in Fig. 2) is' slipped onto the pin point and pressed into position, so that said point and the adjacent portion of the pin enter, slightly expand and engage the spiral coils of the spring E with considerable power, sufiicient to, maintain its attachment. The flaring portion 6.01 the bore of the guide C facilitates the insertion of the pin point. The protector can be withdrawn from such engagement with the pin point by pulling it off, and then the pin can be removed from the hat.

The function ofthe projection F is to prevent backlash of the spring E, whenever the pin is 'pressedinto the protector D, or pulled therefrom. As this projection enters be:

tween two adjacent coils of the spring IE, it-

provides the necessary resistance in both directions when the pin is thrust or withdrawn.

The tubular case D is indicated by the dotted lines-in Fig. 2 and is almost entirely con- .cealed by scrollwork G, of any desired pattern, or by any other ornamentation.

I claim as a novel and useful invention and desire to secure by Letters Patent 1 In a hat-pin, the combination of a pin having a 'pointed end; a tubular guide throughwhich the pin can be moved; a

tubularfca'se secured to the guide; a spiral spring in the case adapted to receive and engage the pointed end of the pin; and'a projection extending from'the case between adjacent coils of the spring.

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

DAVID M. IVATKINS.
