CLASP PIN Filed 'April 13, 1940- INVENTOR. FT A/EUL/NE/` A from/Ey Patented Jan. 7, 1941 UNITED STATES PATENT OFFICE 7 Claims.

This invention relates to pins or clasps, and more particularly to clasps for securing catamenial pads firmly to the belt member to which they are commonly secured by safety pins. A fault of the latter is that the pin frequently opens with resultant slipping of the pad and often with scratching of the wearer. The present clasp or fastener is of such positive locking characteristics that it cannot possibly become unopened excepting when desired, and its durability is such that it is preferred to term it a life pin.

The clasp including all the parts thereof may be made of any desirable material, preferably metal which may be finished, coated or plated in any desired manner.

The above and other objects will become apparent in the description below, in which like characters of reference refer to like-named parts in the accompanying drawing, forming a part hereof.

Referring briefiy to the drawing,

Figure 1 is a fragmentary front View of a catamenial belt showing the clasp in position securing the upper end of the pad to the crotch member of the belt.

Figure 2 is a front view of the clasp in extreme open position.

Figure 3- is a cross-Sectional View taken on the line 3--3 of Figure 2.

Figure 4 is a view similar to Figure 3 but showing the clasp in closed position.

Figure 5 is a cross-Sectional view taken on the line 5-5 of Figure 1.

Referring in detail to the drawing, the numeral IB indicates the belt having the crotch member ll, to the lower end of which the wrapping |3 of the catamenial pad Ill is secured. A substantially rectangular member l5 is sewed on the front face of the member i l along its opposed horizontal sides, leaving the right-hand end side or member IB free with respect to the member H. The opposite end member is split into two parts which provide aligned hinge pins I'l.

A strip-like tongue l8 has one end split and rolled up to provide a pair of aligned hinge sleeves l9 which are pivotally mounted on the hinge pins ll, the adjacent ends of the latter being bent as shown after mounting the hinge sleeves thereon, to retain the latter on the pins.

A row of prongs 20 projects from each of the opposed edges of the contact side of the tongue I8. The free endv of the tongue |8 is bent at an acute angle, as shown, to provide a lip 2l, and intermediate the said lip and the adjacent pair of opposed prongs 20 a transverse bead 22 is formed in the tongue. A sleeve 23 is slidably mounted on the tongue l8 between the lip 2| and the next adjacent pair of opposed prongs 20, and has a raised broad nose 24 extending from the contact surface of the tongue, in a direction to- 5 ward the lip 2l. The sleeve 23 is split at 25 to give it resiliency, that is, to permit it to expand. It is adapted to be moved from the inactive position shown in Figure 3 to the closed position shown in Figure 4, and in doing so it rides over 10 the bead 22, which it may readily do owing to its ability to expand, as above-mentioned. Thus, when in locked position, the bead 22 prevents inadvertent movement out of the locked position owing to the barrier provided by the bead 22.

In use, with the clasp in the open position shown in Figure 2, the upper end of the wrapping l3 is placed against the frame l5 and the tongue I8 is swung down against the same, and in doing so the tongue clamps the wrapping l3 against the 20 frame |5, with the prongs 20 of the latter digging into the wrapping. In the latter position the sleeve 23 at first remains in the position shown in Figure 3, but the lip 2I engages the end frame member l6 in the manner of a jaw, as shown in 25 Figure 4. Then the sleeve 23 is moved over the bead 22 into the position shown in Figure 4, in which the nose 24 passes under the member IS. Thus, the lip 2l and the nose 24 provide the jaws of a resilient clamp tightly clasped about the 30 member l6. To open the clasp, the sleeve 23 is simply slid back over the bead 22 to its inactive position shown in Figure 3.

The prongs 20, by digging into the wrapping l 3, then prevent loosening of the pad I4, while the 35 clasp just described prevents accidental opening or releasing of the tongue IB. Thus a positive securement of the pad to the belt member l I is attained, with no danger of inadvertent opening of the clasp such as frequently occurs when 40 safety pins are used.

Although the invention has been illustrated and described as applied to catamenial belts, it may be used for other purposes as well, and it is not desired to limit its application in any way. Obvi- 45 ously, modifications in form and structure may be made without departing from the spirit of the invention.

I claim:

1. A clasp comprising a stationary frame hav- 50 ing opposed sides, a tongue pivotally mounted on one of said sides and having a lip projecting at an angle from the free end thereof, a sleeve slidably mounted on said tongue and having a raised nose projecting toward said free end of the 55 tongue, said tongue being adapted to be swung against said frame, said lip in the latter position of said tongue engaging one side of the other of said opposed frame sides, said sleeve being slid toward said free end of the tongue to cause said nose to engage the other side of said last-named frame side.

2. A clasp comprising a stationary frame having opposed sides, a tongue pivotally mounted on one of said sides and having a lip projecting at an angle from the free end 'of saiditongue, a sleeve slidably mounted on said tongue and having a raised nose projecting toward said free end of said tongue, said tongue being adapted to be swung against said frame, said lip in the latter position of said tongue engaging one side of the other of said opposed frame sides, a transverse bead or the like on said tongue near said free end thereof, said bead being positioned between said sleeve and said lip when said clasp is in unlocked condition, said sleeve being resilient and being slid toward said lip over said bead to engage said nose with the other side of said last-named frame side to lock said tongue against said frame.

3. A clasp comprising a stationary frame having a pair of opposed sides, a tongue pivotally mounted on one o-f said sides and having a bent jaw on the free end thereof, said tongue having a slidable jaw thereon, said bent jaw upon swinging of said tongue against said frame engaging one side of said other opposed side, said slidable jaw being slidable toward said free end of the tongue to engage said last-named opposed side on the other side thereof, and means for retaining said slidable jaw in said last-named position.

4. A clasp in accordanceiwith claim 3 wherein said means consists of a bead or the like on said tongue intermediate the length thereof.

5. A clasp in accordance with claim 3 wherein said means consists `of a transverse bead or the like on said tongue near said free end thereof.

6. A clasp in accordance with claim 3 wherein said means consists of a bead or the like on said tongue intermediate the length thereof, and wherein said tongue is provided with a plurality of prongs extending from that surface thereof which is adjacent said frame when said tongue is in said swung position.

'7. A olasp in accordance with claim 3 wherein said'means consists of a transverse bead or the like on. said tongue intermediate the length thereof, and wherein said tongue is provided with a plurality of prongs extending from that surface thereof which is adjacent said frame when said tongue is in said swung position.
