SNAP-FASTENER TOP.

Specification of Letters Patent.

Patented Oct. 13, 1914.

Application filed December 24, 1913. Serial No. 808,567.

To all whom it may concern:

Be it known that, I, ABRAHAM H. GREENE- naou, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented a certain new and useful Improvement in Snap-Fastener Tops, of which the following is a full, clear, and exact description.

This invention is in the nature of an improvement on the invention disclosed in my application for patent filed March 26, 1913, Serial No. 757,031 (Patent No. 1,084,269, granted January 13, 1914).

If a highly embossed design is to be made, the celluloid or plastic cover must be drawn deeper than where the design is not in such high relief, and it has been found that in such case there is a tendency for the peripheral fingers of the cover to work loose or pull out if not properly held in position.

The present invention is designed to meet this exigency, and to this end the invention consists of an artificial horn button or top of the character referred to, in which the collet or back has an outwardly extending flange of sufficient length to be closed or rolled over upon the inturned fingers of the cover, to inclose them and securely hold them in position against the possibility of working loose or pulling out, as I will procccd now to explain and finally claim.

7 In the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is a plan view of the plastic cover blank. Fig. 2 is a plan view of the metal filler. Fig. 3 is a top plan view, and Fig. 4 is a cross-section of the spreader or anvil. Fig. 5 is a top lan view, and Fig. 6 is a cross-section of t e improved collet or back. Fig. 7 is an ed e view of the cover and filler blanks asscmbl ed and ready for the simultaneous impressing of the design and the first folding of the cover, and Fig. 8 is a cross-section showing these parts thus treated. Fig. 9 is a cross-section showing the cover, filler, spreader and collet assembled, and Fig. 10 is a cross-section showing these last mentioned parts in finished form. Fig. 11 is a top plan view, Fig. 12 is a bottom plan view, and Fig. 13 is an elevation of the finished top. Fig. 14 is a cross-section like Fig. 10 but showing the top or button set on" a piece of material.

The cover 1, is made from a circular blank, of proper size, cut fromsolid sheet celluloid stock or other suitable plastic stock, and having its rim provided with notches 2 and intervening fingers 3, substantially as shown in Fig. 1, so that when this cover is closed in on the other constituent parts of a button or top the edges of its fingers will abut and the material thus lie fiat and smooth against the back of the button or top.

The filler or backing 4 is a disk of metal, of ap iroximately the diameter of the finished button or top.

The spreader or anvil 5 is of metal, having a central hole 6 surrounded by a frustoconical portion 7. This spreader serves to engage and deflect the leading end of the attaching e elet.

The co let or back 8 is of metal, substantially frusto-conical in form, and having a central opening 9 enough larger than the adjacent part of the spreader to leave a s ace between the two for the entrance of tie attaching eyelet. This collet has an outwardly extending flange 10 which when the parts are assembled and closed upon one another, as in Fig. 10, will overlap the fingers 3 of the cover and securely hold them in lace against the possibility of working oose or pulling out.

As shown in Fig. 14, the eyelet 11 has the leading end of its barrel passed through the article 12 into the top and spread and clenched in between the under side of the spreader and the upper side of the collet.

Excepting for the modification of the collet or back and the provision of the flange 10, overlapping the fingers of the cover and covering them in secure against accidental displacement, the top of this present invention is substantially like that of the invention disclosed in the case referred to, the mode of operation is the same, and all of the advantages of the construction disclosed in the earlier case are inherent in the present invention, in addition to the finger-retaining feature of this present invention.

\Vhat I claim is The improvement in artificial horn tops, comprising a metal filler, a metal spreader, and a metal back arranged in edge contact one upon the other, said back having an outwardly extended central flange, and a in beneath the back and against it, and the solid celluloid cover surmounting the filler sired finish, depth and angularity of the pe- 10 and embossed in position With said filler riphery rendered possible.

and having a rim inclosing the edges of the In testimony whereof I have hereunto set said metal parts, said rim notched and closed my hand this 23rd day of Dec., A. D. 1913.

flange of the back closed down upon the ABRAHAM GREENEBAUM' said notched rim and covering it, whereby Witnesses: the several parts of the top are secured in J. G. ROSENHEDI, place and inseparably united and any de- NATHAN I. HECHT.
