TTACHiNG, PLUG AND RECEPTACLE..

Specification of Letters Patent;

Yntented May 7, 1907.

Application filed October 31, 1904. Serial No. 230,683.

l .To (di whom ir'- may concer-1L:

Beit known that L FRANK C. DE Returns, n citizen of the lnited States, residing nt Schenectady, iii the county of Sclienwindj:

ing device hai-ving corresponding contacts in engagement with the branch conductors and adapted to lie moved into and out of engagement by hand. jectioiinhle for the reason that the circuit-is Vinade and broken li'v the engage-nient or disdoctor, and n receptacle. having a corrcspond- 'ing pair of terminal contacts, e 'pair ol hindengagement of contacts, and because of the lack of e snep-action the)v soon become pitted and destroyed hy the nrcii'ig act-ion between them.

The Object of my invention is to provide a sir'nple and collina-ct att-itching .device for branh circuits which may he connected and disconnected withoutarcing between contacts, fand a further Objectis to provide a. device of this character whichY cannot be disconnected while current is pessing in the branch conductor.

In'cfirljiiig out my invention, l providea.

plug having a pair of contacts connected in the. usual way to the ends ot' vthe branch coning posts for engaging the iiiain conductor, a Simp-switch for electrically connecting one or liotli of the contat-ts with the iespecti ve hind ing post or posts, niid i liolt or 'locking devicendapted to eiign c ai Contact on the plug and controlled liv the snap-switch.

The iniention will be more readily under-I stood by reference to the following detaileddescription zind the :icconipzin-ving drawing forming n part of this specilicetioii in which,

Figure 1 is mi end elevation of an attaching device embodying one forni of niv invention; Fig. 2 is ai top plan Oi the recept-ticle with the face plate ieiiioved; and Fig. 3 is a longitudinal section of the receptacle on line. 3 3 of Fig.

These prior devices are Ob- The plug consists of an oblong knolil hnv` ing n central envitj: in which are arranged binding posts2 iorst-wuring the ends of the h rniirli conductors which are led through the top ol' the knol), sind projecting from the lower end oi the knol: are. two contacts 3 respectively connected at their upper" ends witli the binding posts and having halb g sho-pcd extremities 4 split longitndinellyto render theni slightljv yieldalile.

.to receive a locking bolt 23.

The receptacle is designed to he secured in a recess in a iva-ll and coiisis ts of a. hase 5 lieving end ears 6 .for securing it in place and e.

fa-ce plate 7 adel ted to lie'secured'tliereto and provided wit 'hushed apcrturesS for the passa-ge therethrough otI the plug contacts 3 and an unhiislied aperture 9 forthe. passa-ge of the switch-actuating means. i

The hase 5 is of insulating materiel andin the. forni of e. rect-iingular slab. At the leftliand end of the hase two cylindrical cavities 10 are formed in which tubular contacts 11 12 are secured by' screws 13 extending-'vertically through metallic connecting strips 14 and 15, and walls of the base' and screwthreaded into the ends of the conta-ets. The connecting strip '14 extends through a short channel in thelowcr Vside 'of the Abese to' a.

screw 1,6 which connects it Withe binding` post '17 arranged in a depression 18 in the top side of the base and adapted to connect with e main conductor wire 'adopted to be passed through a hole 19 extending `through the basein proximity .to the binding'post. The. other connect-ing strip 1 extends through e longer channel in the. lower side of the base. to a screw 2() which connectsit with a yoke piece 21. The yoke piece 21 is arranged in 'a depression inthe top side of the bese and consists of a. nietal punching with' firms 22 hentup from opposite edges and'tipertured The bolt 2-3 is provided with :i round end 24 which extends through the side oltubular contact 12 sindl roo in T against inform 22 and a collar 26.fixed to the bolt.

"Vlie snep-switch 2T is arranged in a recess communicating with the recess lin-wliicli the yoke piece 21 is arranged, and nitty be of any approved construct-ion. The switch-blade. 28 has its ends bent up parallel tothe axis,

and the springlclip's 29 80 are dis osed on opposite sides in line with the loe ing bolt 23 so that when the switch-blade is in closed Eostio'n it will engage the rear end of the olt and-"prevent its retraction' while .the

switch remains closed.

' The left-hand. clip 29 is secured between i i the surface of the bas'eand the under side of theyoke-pieoe 21, and the right-hand clip 3()- V1o 'is secured between the stuffaee'of thev base and the bottom of the Second binding post 31 located at the right-hand end of the main base cavity and adapted to engage a main conductor Wire lead lthrough aV hole -32 in proximity thereto.

I do not desire to restrict myself to the particular form or arrangement 'ofv parts herein described and shown, 'sinceit is a parent that they'n'iaybe changed and mo iled without departing trom my -invention.

.VVhatl claim ae new and desire to secure V by Letters Patent bf the United States, is,

1. The ooinbin i `:ion of an attaching plug, a receptacle there fr, means for locking said plug in ,engageinentV with said receptacle, and

a Switclrmounted on said receptacle and provided Witlra rota-iftY @onta-et ada ted 'to close the circuit and secure said oeking means..

'2. The eombinalt'ion of an attaching plug;

lthe end of said holt.

a receptacle therefor rovided withv terminal contacts, a looking Eolt with one end arranged in proximityv to one of said terminal contacts, and a switch mounted on said reeeptacle and provided with a rotary Contact 35 adapted to -elose the circuit and engage the opposite end of said bolt.'

' 3. The combination of an attaching plug L ,provided with independent contacts, a receptacle therefor 'having stationary eon- 4o taots secured thereto, a spring pressed bolt arranged in line with one of the stationary o ontaots7V and a rotary switch' mounted in said receptacle and-adapted to abut against 4:. The combination of an attaching plug havingindependent contacts with enlarged ends,-a receptacle therefor having eu shaped stationary contacts; a spring presse bolt extending at one endthrough the side of a. 5o

stationary Contact, and a rotar)v switchI adapted'to engage the opposite end of said bolt -and prevent retrograde movement thereof` In. Witness whereof,4 I have hereunto set 5 my hand tliis;- Z7tl Lday of October, 1904. v .L 7 RANK-0.41313 REAMER.
