B. B. MANASTER CLASP Filed May 27, 1933 INVENTOR flan B. Mazzagzvf I I a i9 Z2 g4 f5 ATTORNEY WITNESS:

Patented Oct. 17, 1933 UNITED STATES PATENT OFFICE 11 Claim.

This invention relates to a clasp, and has for its principal object the provision of an improved construction of this character which will be highly efiicient in use and economical in manufacture.

Among the several objects of this invention is the provision of a clasp for gripping the opposite edge portions of the. wings of a collar or for conmeeting the lower portion of a tie to a shirt to hold the tie in proper position.

A further object of the invention is the provision of a clasp which requires the minimum effort to attach or detach in position.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing showing the preferred form of construction, and in which:

Fig. l is a perspective view of a collar and tie showing my invention associated therewith;

Fig. 2 is .a detail view of the same taken substantially on line 22'of Fig. 1;

Fig. 3 is an enlarged view of the same similar to that shown in Fig. 2 illustrating certain parts in cross-section;

Fig. 4 is a sectional detailview of the same taken substantially on line 44 of Fig. 3;

Fig. 5 is an end view of the same taken substantially on line 5-5 of Fig. 3;

Fig. 6 is a perspectiveview of the invention;

Fig. 7 is a perspective view of a gripping element embodied in the invention illustrating a slightly modified form of construction over the gripping element illustrated in Figs. 1 to 6 inclusive; and

Fig. 8 is a sectional detail view of the invention illustrating a modified form of construction.

Referring more particularly to the drawing in which the clasp embodying the invention is illustrated and in which the preferred form of construction of the same is shown, 10 indicates a front bar having its medial portion provided with a concave portion 11 and provided at its outer d with ornamental elements 12, which in the present instance are in the form of spherical elements with their undersides flattened as at 13. These ornamental elements may vary in design according to the desire of the manufacturer or designer.

The clasp further includes a rear bar member 14 having its intermediate portion connected to the concave portion 11 01' the front bar 10 by means of a band 15 or the like. The outer end portions of this bar member 14 are flattened and prevent displacement of hereinafter described.

Slidably mounted for longitudinal movement on the bar member 14 between these lips 16 and the band 15 are gripping elements 18. These gripping elements 18 are tapered in opposite longitudinal directions to provide a relatively small gripping area 19 which is adapted to grip the fabric 17 in the manner shown in Fig. 2. These grip- These springs 20 also function to resist movement of the gripping elements 18 from gripping position, and the tension of these spring members is such that the gripping elements will slide with ease over the surface of the fabric whenvthe same is positioned between the jaws provided by the ping elements into gripping position to prevent displacement of the clasp when mounted upon the fabric.

While in the drawing I illustrate the clasp comprising two interconnected bar members, which as hereinbefore explained are connected together by means of the band 15, it is manifest that these bar members may be formed as an integral unit without departing from the spirit of the invention. The advantages of my clasp over the clasps now commercially in use reside in the fact that there is-nothing embodied in the structure of the clasp which will cause tearing of the piece of fabric or snagging the threads thereof. Nor will the same leave a'mark or impression upon the fabric when removed therefrom. I

The clasp as shown in the drawing'is. espec designed for use in connection with the wing's of a shirt collar. However, it is apparent that the principal involved may be adaptable for use in of the rods are angled and fixedly connected in the elements 19 as at 24. The adjacent inner ends of these rods are small pellets 25 to fac' 'tate moving the rods toward each other to retract the elements 18 from gripping position.

while I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. 1, therefore, do not wish to be limited to the precise details of construcforth, but desire to avail myself of such variations and modifications as come wi scope of the appended claims.

Havmg thus described my invention, what I claim as new and desire to protect by Letters Pat,- ent is:

1. A clasp comprising a pair of bar members connected together intermediate their end portions and providing oppositely disposed gripping jaws adapted to slidably receive the wing portions of a collar, and spring urged means adjacent the entrance of said jaws and adapted to eifectuate gripping of said wing portions by said jaws.

2. A clasp comprising a pair of bar members interconnected together intermediate their end portions to provide oppositely disposed jaws adapted to slidably receive fabric therebetween, and means slidable on one of the said bars to effectuate gripping of said fabric'by said jaws.

3. A clasp comprising a pair of bar members together intermediate portions to provide oppositely disposed jaws adapted to slidably receive fabric therebetween and spring urged means slidable on one of the said bars'to effectuate gripping of said fabric by said jaws.

4. A clasp comprising a jaw, disposed to receive a piece of fabric, and a gripping element slidably mounted upon one of the elements of said jaw to effectuate gripping of the fabric by said jaw, said gripping element being tapered in opposite longitudinal directions to provide a medial portion of a relatively small bearing surface adapted to engage the fabric.

5. A clasp comprising a jaw disposed toreceive a piece of fabric, and a spring urged gripping element slidably mounted upon one of the elements of said jaw to effectuate gripping of the fabric by said jaw, said gripping element being tapered in opposite longitudinal directions to provide a medial portion of a relatively small bearing surface adapted to engage the fabric.

6. A clasp comprising a bar member having a concave portion intermediate its end portions, a second bar member disposed longitudinally with respect to the first bar member with the concave portion disposed in abutment with the intermediate portion of the second bar member, means connecting the concave portion to the said intermediate portion of said second bar member,

their end one provided with springs 20 the retracting rods 23. The outer ends gripping elements slidably mounted on said second bar member and adapted to co-operate with the bar members to effectuate gripping of a piece of fabric therebetween, and means for resisting movement of said gripping elements.

'7. A clasp comprising a bar member having a concave portion intermediate its end portions, a

second bar member disposed longitudinally withrespect to the first bar member with the concave portion disposed in abutment with the intermediate portion of the second bar member, means connecting the concave portion to the said intermediate portion of said second bar member, gripping elements slidably mounted on said second bar member and having outer end portions beveled to facilitate movement of the gripping elements over said fabric and to provide a relatively small bearing surface in contact with said fabric.

8. A clasp comprising a pair of bar members disposed insubstantial parallel relation with respect to each other and having their intermediate portions connected together, gripping elements slidably mounted on one of the bar members to effectuate gripping of a piece of fabric between said bar members, spring elements disposed upon said one bar member for urging said gripping elements into gripping position and to resist movement of said gripping elements from gripping position.
