.SPECIFICATION forming part of Letters Patent N 0. 769,208, dated September 6 1904.

Application filed December 29, 1903. Serial N0.186,999.

To aZZ whom it may concern.-

- Be it known that I, WILLIAM E. CoLEs, a citizen of the United States, residing at Attleboro, in the county of Bristol and State of Massachusetts, have invented a new and usefollowing is a specification.

This invention has reference to an improvement in fasteners, and -more particularly to an improvement in that form of fasteners used to fasten or secure articlesto wearing apparel or to fasten articles of wearing-apparel together. In fasteners or clasps of this nature as heretofore constructed two operations are requiredan operation of the mechanism to secure the fastener and an oper-' ation 'of the mechanism to release the fastener from the outside of the wearing-apparel to which it was attached.

The object of my invention is to improve the construction of a fastener, whereby the fastener is secured to an apparel automatically and released by pressure on a lever in the fastener.

My invention consists inthe peculiar and novel construction of a fastener having a U- shaped frame stamped from sheet metal having a spring tension, a spring-tongue, bearings, and an eye formed integral with the frame, a fastening-leverhavingpivots working in the bearings and held in its closed position by the spring-tongue, and a cap adapted to cover the front of the fastenerand hold the fastening-lever in its operative position in the frame, hereinafter. I

Figure 1 is a plan View of the blank forming the U-shaped frame of the fastener, showing the spring-tongue, bearings, and the eye formed integral with the frame. Fig. 2 is a plan view of the blank forming the fastening-lever,showing the pivots, corrugated end, Fig.3 is a plan view of the blank forming the cap, showing the aperture through which the fastening-lever extends. Fig.4 is a front completed fastener constructed from the blanks shown in Figs; 1,2, and 3; and Fig. 5 is a sectional view taken on line X X of- Fig.

article of wearing-' as will be more fully set forth view of the to move the end 6 (No modeLl 4, showing the fasteningdever closed in full lines and in the open position in broken lines.

In the clrawings, a indicates the U-shaped frame, 5 the fastening-lever, and 0 the cap of my improved fastener. The frame a is stamped from" sheet metal having a spring tension and bent substantially U shape to form the back ct and .the front (6 The springtongue (6 which bears on the fastening-lever, the stamped-up bearings a (o for the pivots of the fastening-lever, and the eye a for attaching articles to the fastener are all formed in the front a integral with the frame. The fastening-lever t has the pivots b 5, the inner corrugated end 5 and the' outer end formed into the thumb-piece 6 ,The cap a has the aperture 0 for the fastening-lever and is secured to the front a? of the fastener by rolling the edges 0 0 over and under the edges of the frame. The cap 0 has preferably an ornamental design, as shown in Figs. 3 and 4.

When the parts of the fastener are assembled, the fastening-lever 5 extends through the openinga on the front a of the frame between the bearings a (o The pivots 6 6 of the fasteningdeverb are held in the bearings a (t in the frameby the face of the cap 0. The spring-tongue'a exerts a spring tension on the fastening-leverb to hold the end 6 against the back t' of the fastener. The

thumb-piece Z on the fastening-lever extends the lever forward against the tension of the spring-tongue C63. The end 6 of the lever is now forced into the fabric by the tension of the spring-tongue, securely holding the fastener to the fabric. Stantly released from I the fabric by pressure on the thumb-piece b of the fastening-lever of the lever forward, as

shown in-broken lines in Fig. 5.

The fastener when once secured 1s practl- The fastener may be incally locked to the fabric and cannot be released except by pressure on the thumb-piece 0f the fastening-lever. An upward movement of the fastener by accident or other means tends to force the inner end of the fastening-lever more firmly into the fabric.

By my improved construction of a fastener the fastener is automatically secured to the fabric and is instantly released from the fabric when required.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- In a fastener, a U-shaped frame, a springtongue, bearings, and an eye all formed integral with the frame, a fastening-lever hav-
