Application led leoember 17, 1908.

America, and residing at Bridgeport, in the county of Fairfield and State of Connecti- Cnt, have invented certain new and usetnl improvements in Binding-Posts. ot which the following` is a specification.

iiy invention relates to eleetrieal binding posts and particularly to binding;` posts tor Specicaton of Letters atent.

rotary snap switches, the objeet ot' my in\'en i,

i sinned in wrappingy the wire end around the tion being` to provide an improved post in which the necessity torwrappinggq the wire beneath the head ot' the binding screw is eliminated.

ln the aeeomjnmying drawings in which my invention is illustrated, Figure t is a per spectire ot a yporcelain switch base of oommon construction upon which bindingposts enibodyintl my invention are mounted; Fig. 2 is a partial pian ot" the same; Fig. 3 a Vertical section on the line {EL-3, Fig. 2; and Fig. i is a perspective ot a modified Vtorni ot' post.

In these drawings only sutiieient ot the base and bindingl posts to illustrate the pres ent ii'ivention has been shown.

My improved binding posts, in the t'orm illustrated, are, adapted t'or use with a rotary switch member ot' the type illustrated in the 'thomas jatent No. (3875095 that a rotary switch member having contact clipsl to eii'ilnfaeei matie contact with and slide over a blade earried by each bindingl post. is shown, the base .i has vertical passages lt) formed therein throat-li which the leadingin wires may be threaded directly to the bim'lin;l posts.

Each binding post is l1ormed trom sheet metal stamped up to torm a horizontal base pieee l1. with lateral wings l2 having threaded openings lli to receive the usual securing screws tl, which are set in trom the underside oi the base. 'the contact blade l5 projects horizontally t'rom between the wings l2, while the standard lt is angled into substantially Vertieai position and provirfled with a clamp t7 through which the binding screw 18 is threaded.` This clamp is formed in the blank by stamping` out a laterally projerting wing' on the standard It) which subsequently i'olded over and the hole l) .l'or the bindingr screw punched and tapped'. To hold the wire in position it is Patenten nitty 3i, toto.

desirable to groove the wings of the clamp at fe, though it sntlieient'i't the groove be formed in one wing only, as in Fig. '4. The; :groote is located in line with the ent away portion 1/ ot' the base piece and the post is secured npon the insulating base A so that tlfe parts ic and bl/ are a'lined with the pas- 10. and the leadiiigdn wire may thus be easily threaded np into the groove u; of the elamp. 'Ibis is a coiisiderable convenience as it Saves the time ordinarily conbindingr screw. and furthermore a greater contact surtaeeis presented aml a surer contact made by the clamp than when the wire is merely" twisted around thewbinding screw and secured beneath the head of the latter.

iclaim as my intention:

i. .lt combined eontart and binding post7 comprisingv a base Vwith laterally extending perforated seem-ink;r ears and a contact blade integral therewith and projecting;l between i the same. together witli an integral upright standard baring;4 a lugr'strueli' therefrom and bent around to l'orm a chimp and an actuating; screw passing' through the members ot the chimp, said base being cut away between the laterally extending ears to leave clearanee tor a leading-in wire, and said 'lun1p bein;V lot'atett thelem'er `to reeeiye Isaid wire` substantially as described.

2. .in insulating base ot a' rotary snap :switch lia-vint,r holes for the passage ot the wires. together with an integral combined contact. and binding; post comprising a-base pieee with laterally extending ears/'and a contact blade projecting between thel same, together with an uprit'ht standard having a lug bent aroimdto t'orm a binding clamp7V and an aetuating'scrow passingthrough the members ot' the clamp, srid base being eut away between thelatorally extending ears to leave clearance for a leading-in wire and said clamp being loeattal over the wire hole in the bas*l and adapted to receive the leading-inwire threaded therethrough, substan tially as described.

il. blank tor a combined Contact. and bindiin;- post. comprising a metal lstrip having one end shaped 'for a contat-ty blade, a

base portion adjacent said blade having' perl'orated lugs oxtemlingi laterally on either side of said blade, a post portion adjacent said base portion havinn a lateral tlange :ulnplcd to he, lient around to forni a clamp, smid hugo portion being perforated t0 afford 11mm-:inve for .the lending-in wire and said pmt and clamp-lng portims being perforated with halos of the saine size adapted to he brought into register and ihreaded to rewive :in zictnaiing screw.
