WIRE CRIMPER.

Applicatonled January 29, 1925. Serial No. 5,495.

`This invention relates to new and useful improvements in wire crimpers.

The primary object of the invention is to provide a machine adapted for crimping wire mesh, or the like, which is fed through the machine in web form.

A further object of the invention is to provide a machine adapted for forming different sized and vshaped crimps and for arranging the various crimps in longitudinal alinement or in staggered or overlapping relation in respect to the length of the web of material being handled.

l Other objects and advantages of the invention will be apparent during the course of the following description.

Figure 13 illustrates in fragmentary per spective a crimping or die element adapted to be associated with the roll illustrated in Figs. 5 and 6, and

Figure 14 illustrates in perspective the type of removable crimping or die elements shown associated with the roll illustrated in Figs. 7 and 8.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of this invention, the numeral 5 designates the'base plate of the frame portion of laids in bracing and maintaining in alinement the said skeleton sides.

Journaled in the central bars 8 are the parallel, transversely extending shafts 11 and 12 which are connected to rotate at the ysame speed by the spur gears 18 and 14. The shaft 12 is provided with a fixed pulley 15 and a loose pulley 16 adapted to be associated with a drive belt extending from a suitable source of power, not shown.

Mounted upon the shaft 12 and suitably keyed, splined, or fastened thereto is what will be termed the female crimping or die roll 17 This roll 17 has formed in its periphery four equi-spaced, longitudinally extending grooves 18 which are of square or rectangular formation in cross-section and extend the full length of theroll. Removably fitted in these 4grooves 18T are the metallic 'female die elements `-19 depicted in detail in Fig. 12. This roller yis further provided with Afour equi-spaced, longitudinally extending grooves 20 which are V-shaped in cross-section and have removably fitted therein the metallic crimping or die elements 21 which are depicted indetail in Fig. 13. These grooves and elements 2O and 21 also extend the full length of the roll 17.

Similarly mounted upon the shaft 12 is the male crimping or die roll 22. This roll 22 is adaptedfor having removably mounted upon its' periphery the male `die elements kie 23 which areVshaped in cross-section and register withfthe `\/#shape`d lifeinale die ele-` ments 21 when` the rolls 17 4and "22 are rotated. This roll 22 isillustratedr in Figs;
