Application June 2, 1937, Serial No. 146,106

Renewed March 9, 1939 Claims. (Cl. 85-1) This invention relates to studs especially adapted for use in lieu of shoulder screws or screws and lock nuts on stripper plates, knockout plates or pads and the like on sheet metal dies and has for the primary object the provision of an efiicient non-breakable and inexpensive device of this character which may be employed as a pilot for the die spring and will limit the distance of travel of the stripper plate or other similar element as above mentioned and the die shoe away from each other and yet permit,

free travel towards each other and may be easily and quickly assembledfrom the side in which the springs and stripper plate or other element are assembled.

With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For acomplete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 'is 'a fragmentary'vertical sectional view showing a stripper plate and dieshoe connected by a stud constructed in accordance with my invention. I v

Figure 2 is a side elevation, partlyin section, illustrating the stud detached from the stripper plate and die shoe.

Figure 3 is an .end View showing one end of the stud.

Figure 4 is an end view showing the other end ofthe stud.

Figure 5 is a sectional view taken on the line 5--5 of Figure 2.

Referring in detail to the drawing, the numeral I indicates a fragmentary portion of a stripper plate and 2 a fragmentary portion of a die shoe. Interposed between the stripper plate and die shoe is a coil spring 3 seating in a socket 4 formed in the die shoe. The stripper plate and die shoe are found in the construction of sheet metal dies and in order that these parts be joined for free movement towards each other and for limiting the movement away from each other my invention is employed and which also by extending through the spring 3 acts as a pilot therefor. The stripper plate and die shoe have axially alined openings 5 in which are received the end shanks 6 of my invention which includes a pair of interconnecting links 8 each of substantially rectangular shape and split to permit the assembling of the links together. As shown, the

bore of the opening 5 in the stripper plate I is plain and smooth but the bore of the alined opening 5 of the die shoe 2 is screw-threaded.

The shanks 6 are integral with the links and each screw-threaded from its outer end to an inner base shoulder andthe splits in the links also extend through the shanks. The parallel side portions of the links have beveled faces 9. The beveled faces of one link have sliding con-, tact with the beveled faces of the other link. One of the shanks is drilled axially and internally screw-threaded, as shown at 10, in which may be threaded a suitable tool to aid in the assembly of the stud of my invention in the die shoe and stripper plate.

To assemble the stud the non-socketed shank thereof is threaded in the opening of the die shoe and the spring 3 placed to surround the stud. In order to draw the socketed shank through the opening inthe stripper plate a suitable tool is passed through the opening of the latter and threaded in the .socketed shank so as to draw the same through the opening of the stripper plate and permit a nut II to be threaded thereon. The stud of the construction described will limit distance of travel between the stripper plate and die shoe under the influence of the spring, also act as a pilot for the spring and permit free travel of the stripper plate and die shoe towards each other. i

What is claimed is:

1. A stud comprising interconnected links capable of a limited sliding movement relative to each other and each split at one end, split screw threaded shanks integral with the split ends of the links, one of said shanks having a threaded socket to receive a threaded tool.

2. A stud comprising interconnected links capable of a limited sliding movement relative to each other and each split at one end, split screw threaded shanks integral with the split ends of the links, one ofsaid shanks having a threaded socket to receive a threaded tool, each of said links being of substantially rectangular shape and the side portions thereof having beveled faces so that the beveled faces of one link may slide upon the beveled faces of the other link.

3. A stripper plate mounting stud of the character described comprising interlooped substantially rectangular open link members providing limited free axial movement but precluding appreciable relative angular or lateral movement between the members, one of said'members being provided with means at its outer end portion for rigid connection to a die shoe and the other with opposed means at its outer end portion for rigid connection to a stripper plate.

4. A stripper plate mounting stud of the character described comprising interlooped substantially rectangular open links providing limited free axial movement but precluding appreciable relative angular or lateral movement between the links, said links being formed at remote ends with integral axially alined screw shanks for connecting them respectively to a die shoe and a stripper plate.

5. A stripper plate mounting stud of the char,-

acter described comprising interlooped substantially rectangular open links providing limited free axial movement but precluding appreciable relative angular or lateral movement between the links, said links being formed at remote ends with integral axially alined screw shanks for connecting them respectively to a die shoe and a stripper plate, the respective links being split longitudinally through the axes of their shanks and adjacent body portions.
