Jan. 12, 1960 E. D. JANES ETAL FASTENER SETTING TOOLS Filed Sept. l5, 1957 s 7 R Y osn E Te N R vJw m N J T ID 6 .7l 2 .W BM um! i .ff rates FAS'IENER SETTENG TLS Application September 13, 1957, Serial No. 633,894
1 Claim. (C1. 1 4) This invention relates to hand tools for the type used for setting stud and socket parts of a snap fastener upon a piece of fabric or the like.
One of the faults with such tools in the past was that when the prong ring element of the fastener parts was placed in the lower die it projected above the die to such an extent that it would often be knocked out of position when the support material was being inserted into the tool.
It is one of the objects of our invention to overcome the above fault so that there will be little, if any projections of the fastener elements above the die surface such as to interfere with the assembly of the garment support.
Another object of the invention is to provide a onepiece setting punch which will have means for gripping the prong ring so that it is out of the way of the material being inserted prior to the fastener setting operation.
Other objects and advantages of the invention will be apparent from a consideration of the accompanying drawing and annexed specication illustrating and describing one embodiment of the invention.
In the drawings:
Fig. l is a perspective view of the fastener setting tool embodying the invention.
Fig. 2 is an enlarged sectional view of the lower end of the punch.
Fig. 3 is an enlarged fragmentary and sectional view of the punch and die showing one set of fastener elements in place prior to the setting operation.
Fig. 4 is the same as Fig. 3 except showing the tools in the fastener-setting position, and
Fig. 5 is a similar view to Fig. 3 but showing a different set of fastener elements assembled into the tools.
Referring new to the drawings there is illustrated one preferred embodiment of the invention suitable for applying snap fastener elements such as disclosed in the Fenton Patent No. 2,131,347 to a garment support S usually of textile material. The fastener members consist of a prong ring and a fastener socket 11. The prong ring 10 is in the form of an annulus 12 having a series of tapered prongs 13 projecting downwardly from its inner circumference. The socket 11 is formed with the usual resilient fingers 14 surrounded by an anvil portion 15 terminating in a clincher rim 16 of arcuate shape in cross-section. The anvil portion 15 serves to deflect the prongs of the prong ring outwardly and the clincher rim 16 serves to upset and clinch the end of the prongs during the fastener setting operation. Also, as shown in Fig. 5, one of the fastener elements may consist of a stud part 17 having a surrounding anvil portion 18 terminating in a clincher rim 19 similar to the like parts in the socket 11.
The tool for setting the above type of fastener elements upon a garment support S is best shown in Fig. 1 and consists of a base 20 of relatively thick material having an integral bracket 21 extending upwardly from one end and supporting an arm 22 superposed above said base. The arm 22 terminates in a guide bearing 23 for slidably receiving a setting punch 24. The base 20 is formed with a die recess 25 and a counter recess 26 therein. The guide bearing 23 on the arm 22 supports the setting punch 24 in axial alignment with the die recess 25. The die recess 25 is of a suitable size to receive the anvil and clincher rim of both the socket member 11 and the stud member 17, and is of such a depth that said members 11 and 17 will project only a slight distance above the upper face of said base. It will be noted from Fig. 5 that the counter recess 26 in the die recess 25 is adapted to receive the head of the stud member 17.
The setting punch 24 is preferably made of nylon material so as to have some degree of resiliency for reasons as will appear later. The upper end of the punch 24 is formed with a rounded surface 27 against which a suitable instrument of sucient weight, such as a hammer, may be struck during the fastener setting operation. The lower end of punch 24 is formed with a tapered surface 2S terminating in a relatively short cylindrical neck 29. A recess 3ft is formed in the end of the punch and also a counter recess 31. The inner Wall of the recess 30 is undercut at 32 and thus provides `for a continuous circumferential or annular lip 33 having some degree of resiliency. The recess 30 is dimensioned to receive the annulus 12 of the prong ring 10 and specifically the inner diameter of the extreme lower end of the lip 33 is slightly less than the diameter of the prong ring annulus 12 so that when the prong ring is forced up into the recess 30, the annular lip 33 will hold the prong ring on the end of the punch preliminary to the fastener setting operation. After the setting operation, the assembled fastener parts on the support and the tools will appear as shown in Fig. 4 where it will be noted that a portion of the support material S will be forced up through the opening in the prong ring 10 and be received in the counter recess 31 of the punch 24.
It will be noted from the above description and the accompanyingl drawing that the tool is very simple in construction, consisting of only two parts, and that the punch is of such construction that it can receive and hold the prong ring in elevated position in line with its complemental part assembled in the base preliminary to the insertion and proper location of the garment support.
We claim:
A tool for attaching snap fastener elements to `a support, one of which elements consists of a prong ring and the other element consists of a fastener member having an anvil portion for deecting the prongs of the prong ring during the fastener setting operation, said tool comprising a base having a die recess for receiving the fastener member in an inverted position with the anvil portion directed upwardly, an arm superposed above said base and having a guide bearing in axial alignment with said die recess, and a one-piece setting punch slidable in said guide bearing, the lower end of said punch being a pliable plastic material and having a depending continuous circumferential resilient lip, said lip having an interior undercut, the lower inner edge of which is slightly less in diameter than the prong ring annulus and wherein said lip is capable of snapping over and grippnig the periphery of the prong ring with prongs projecting downwardly in line with the anvil portion of the element fitted in said die recess.
