CLASP FOR RUBBER APRONS.

Application filed January 25,1924. Serial No. 688,372.

To all whom it may concern.

Be it known that I, EUGENE W. RUTHER- ronn, a citizen of the United States, and a resident of New Haven, county of New Haven, and State of Connecticut, have invented a certain new and useful Clasp for Rubber Aprons, of which the following is a full,

clear and exact description.

This inventon relates to clasps for rubber aprons and its object is to provide a clasp of a simple and inexpensive but attractive construction that will hold together the straps of the apron at their place of crossm Tleferring to the'drawings forming a part of this specification, V

Fig. 1 is an apron viewed from the back showing the clasp applied.

Fig. 2 is a view of the clasp, actu'al size, in perspective, and

' Fig. 3 is a development of the clasp showing the blank from which it is formed.

The invention resides in the novel construction of the slide which is produced by so stamping a blank from sheet materialand folding it that an integral structure will be produced consisting of a pair of slots for the retention of the straps of the apron at their place of crossing.

In the preferred embodiment the folded blank forms the entire slide and is shown in the drawings in Figure 3 and designated generally by the numeral 1. The blank is cut from its periphery inwardly at four places and in the present form these cuts are produced by cutting out four V-shaped portions 2, 3, 4 and 5, thereby providing a central body member 6 and four extending members arranged in oppositely disposed pairs 7-7 and 8'-8 integral with the body member and extending from its four sides. A pair of these members as for instance the pair 7--7 is folded over opposite to one face of the body member 6 to form an open slot therewith for the retention of the strap a of the apron A. The other pair 88 of the four members is similarly folded over opposite the other face of the central member to form an open slot therewith for the retention of the strap" Z) of the apron, all as shown in Figure 2. I

The sides of the central member 6 are disposed at angles similar to the angles at which the straps cross, and as these sides form the defining edges for the slots, the

slots will be disposed at the same angle as the straps, thereby maintaining the straps in a substantial straight line as shown in Fig. l. The V shaped openings 2, 3, 4 and 5 are so cut that their sides will be at suitable The central body member and extending members may be perforated in any desired manner to lend to the attractiveness of the clasp and to reduce its weight. In the pres ent instance theffour extensions are perforated forming the large openings 9 havingtheir inner edges 10 coinciding #with the edges of the central member 6. This reduces the extensions to mere U-shaped bars integrally connected to the central member 6, which besides giving a very pleasing appearance to the clasp permits an easier bending of the members over the edges 10 of the central member 6 to form the slots for the straps. This forms a very strong structure which enables theclasp to be made of very light material such as aluminum, celluloid, or the like, or on account of its skeleton formation it may be made even with heavy materials such as thin sheet steel without being objectionably heavy.

The folded extensions have their opposite edges 1l11 slightly spaced apart to form an opening 12. This is desirable for the and being of one piece the angle between the two slots is fixed or determined when the blank is stamped and folded. The slots therefore require no angular adjustment and will necessarily remain at the exact angles produced by the stamping and folding operations which are the angles similar to those assumed by the shoulder straps. Moreover being a one-piece integral structure there is no possibility of the parts getting out of place or becoming detached. As before remarked the sides of the central member and in fact the sides of the clasp itself are relatively disposed at angles similar to the angles assumed by the straps and therefore the clasp has the further advantage of being of a diamond-shaped formation equal in area to the area of the straps at the lace of crossing.

I- aving thus described my invention what I claim and desire to protect by Letters Patent is:

1. A clasp for holding the shoulder straps of an apron at their place of crossing, comprising a single piece to provide a central body member, and four members extending from and formed integral respectively with the four sides of the body member, two of the members being oppositely disposed to each other and folded over opposite one face of the central member to form anopen slot therewith for the retention of one of the straps, and the other two of the four 1 members being oppositely disposed to each other and folded over opposite to the other face of the central member to form an open slot therewith for the retention of the other strap.

2. A clasp for holding the shoulder straps of an apron at their place of crossing, comprislng a single piece to provide a central diamond-shaped body member having its sides disposed at angles similar to the angles of the crossing straps and of an area equal to the area of the straps'at the place of crossing, and four members extending from and formed integral respectively with the four sides of the body member, two of the four members oppositely disposed to each other being folded over opposite one face of the central member to form an open slot therewith for the retention of one of the straps, and the other two of the four members being folded over opposite to the other face of the central member to form an open slot therewith for the retention of the other strap, the folded members on each side of the body member having their. adjacent edges spaced to permit the assembling of the clasp; with the straps.

Signed at Waterbury, in the county of New Haven, and State of Connecticut, this 21st day of January, 1924:.

EUGENE W. RUTHERFORD.
