Y. Application December 24, 1935, Serial No. 55,973 1 Claim. This invention relates to connection devices for attachment to various articles and more par ticularly to those formed of plastic material such as clasps, buckles and the like and especially for 5 use with such articles formed of catalin and cel luloid. One of the principal objects of the invention is to provide attachments for use with such ar ticles having improved means for securing them 10 to the same. Another object is to provide a clasp member which has a base portion of suitable ma terial, and attachments secured thereto, one of which is adapted to have one end of a belt per manently attached to it, and another being a con 15 nection member, such as one having a hook or one having an eye or slot to be engaged by a hook, or other suitable devices adapted to engage for connecting the ends of a belt, said attach ments being provided with my improved means 20 for attaching them to the base portion. A fur ther object is to provide a metallic attachment to which a piece of plastic material such as cel luloid or catalin is secured and which can be ap plied to a clasp or buckle base by cementing or _ pasting it thereto or other suitable manner. The means I prefer to employ for accomplish ing the above objects, together with other ad vantageous and novel features of my invention, 30 are illustrated in the drawing accompanying and forming part of this speci?cation, and in Which Figure 1 is a rear elevation of a clasp employ ing my improved attachments. 35 Fig. Fig. Fig. Fig. 2 3 4 5 is is is is a side elevation of the same. a. front elevation of the same. a plan of the same. a side elevation of one form of my improved attachments. Fig. 6 is a rear elevation of the same. Fig. 7 is a section of the same taken on the line 1-1 of Fig. 6. Fig. 8 is a, side elevation of another form of my attachments. Fig. 9 is a plan of the rear of the same. Fig. 10 is an elevation as seen from the right of Fig. 9. Fig. 11 is a side elevation of another form of my attachments. Fig. 12 is a plan of the rear thereof. Fig. 13 is an elevation as seen from the right of Fig. 11. Fig. 14 is a rear elevation of another form of my attachments, and Fig. 15 is a side elevation of the same. Referring to Figs. 1 to 4 inclusive of the draw ing, the numeral 2 indicates the base portion of an article to be supplied with attachments, in this instance being a clasp for a belt, 3 indicates one of the attachments, and 4 indicates another (01. 24--226) of the attachments. The attachment 3 is illus trated on a larger scale in Figs. 5, 6, and 7, and consists of a raised elongated portion or bar 5, end portions 6, and juncture portions ‘I joined to the end portions. The juncture portions 1 have perforations 8 and attached to the edges of the perforations 8 are prongs or points 9. Attached to the portions 6 are parts ID, in this case said parts being thin rectangular pieces of plastic material such as catalin or celluloid, which 1O parts are held against the faces ll of the junc ture portions '1, the prongs or points 9 being forced through or into the parts I 9 and their ends forced outwardly so as to be well embedded in said parts l0, and to hold the same securely against the juncture portions 1. The portions 5 are attached to the parts In and the latter cut to size all in one operation of a press. The at tachments 3 are adapted to have ?exible mate rial such as a belt attached to them as by looping it around said bars 5. ‘ Figs. 8, 9, and 10 illustrate the attachment 4, which has a hook l4 and a body portion l5 pro vided with perforations 8 and prongs 9. There are parts ll? of plastic material held against the juncture faces l6 of the body portions l5 by means of the clinched prongs 9 embedded in or forced through them. Figs. 11, 12, and 13 show another form of at tachment which is indicated by I1 and consists of a body portion l8 and a front extension I9 3O having a slot 20 suitable for engaging with a book. The body portion has perforations 8 and prongs 9, and there are parts IU of plastic material se cured by the prongs 9 embedded in them, to the body portion I8. Figs. 14 and 15 show a modi?ed form of the attachment 3 and in said ?gures 21 indicates the elongated bar, 22 the bent end parts, and 23 the juncture portions. To the latter are applied the 40 parts !9 of plastic material by the prongs 9 em bedded in them. What I claim is: In a clasp comprising a base portion made of celluloid and a coupling element secured to one of the ends of said base portion, means adhered to said base portion for anchoring the loop of a belt to said base portion, said means comprising a longitudinal ?at metal strip terminating at each of its ends in a ?at tab offset from and par 50 allel to said main body member; a celluloid fac ing covering the outside surface of each of said tabs and adhered to said base portion; and a plurality of prongs struck out of each of said tabs and extending into the celluloid facing immedi 55 ately adjacent thereto for attaching said cellu loid facings to said tabs. ‘ HARRY SHEER.
