My inventionrelates to devices for connectinstance,-binding posts and the like; More specifically, my invention relates to a con necter which may be secured to an ordinary binding post and to which an electric wire 7 may be quickly attached or detached.
drawings in which One of the principal objects of the invention is to provide a connector which will tenaciously grip a rod or-wire inserted therein by spring action and yet provide'adequate and large contacting area between said connecter and rod, so that the connection will be both mechanically and electrically excellent.
Other objects will be apparent from the following description and appended claims when considered with the accompanying Fig. 1 shows a development of a sheet metal tube having slots cut therein, from which'the connection is made. 7 Y Q Fig. 2 shows an elevation of the sheet metal tube from which the connecteris madewith I finger pieces thereon.
Fig. 3 shows an elevation of ready for use.
Fig. 4 shows a plan View of my connecter ready for use, the dot-tedlinesrepresenting the position of the finger pieces when they are rotated to enlarge the throat to allow insertion of a conductor.
my connecter Fig. 5 is a sectional elevation of my con-- I an angular position shown in Fig. 7 The ele? ments 3 will still be straight lines. The figure shown in Fig. 7 isknown as a hyperboloid of revolution and its inner and outer surfaces are knownas warped surfaces.

If thedisks are moved thru a sufl'ici'ent angle the size of the gorge or throatcan'be To apply this to make a good connecter, a material is used which can be worked soft and then subsequently tempered to give spring and elasticityafter the connecteris." 7
sheet brassisasuitable The material maybe initially infeither 5 sheet or tube form. If initially in tubefor'm, as shown in Fig. 2 longitudinal slots 10 are cut in the tube 4' to provide longitudinalstrips or members? connecting an upper ring 11 and lower ring 12. If the inaterial-is initially in sheet form, the longitudinal slotsf 10 "may be cut to providethe, strips/7 while thej'material is in sheetigfbrm.

It should be noted; that as the upper and lower rings are moved from the position shown in Fig. 2 to'that shown in'Fig.- 3, the slots 10 become narrower. In order to'provide maximum {areaof contact between the connecter and an insertedconductor, the distance betweenadjoining elements7 when a conductor is gripped should be substantially zero; Therefore, when form-ing'the connec- "ter, before tempering, the rings '11 and 12 should be moved relatively till the elements 7 touch eachother at the throat or gorge 8, if maximum area of contact is desired.
