g My lnvention may be'further briefly sum In carrying out my invention, I provide a marized as consisting in certain novel details connection plug comprising an insulating Of construction, and comblnations and arbase to which two contact members are s rangements of parts which will be described cured, and a sleeve or shell which is adapted 1n the specification and set forth in the a so to be screwed or otherwise fitted onto the p d d laim base, and to be brought into engagement For an' understand1ng of my invention, with one of the contact members, the sleeve reference 5 ad t0 the accompanying sheet having at its outer end aninsulated contact f drawlngs whereimdisk or plate which is brought into engageam 1 1S aside elevation of a connecs5 nt w1th th oth r ta t member h tion plug constructed' n accordance w1tl? my the sleeve is placed in normal-position on 1 n 10n, he plug being shown on ashghtly the base. enlarged scale; Fig. 2 1s a longitudinal sec- More specifically considered, the invention tlfmill W Of the a nd Fig. 3 is a plan consists of a connection plug comprising an new of the plug WltlI the sleeve or shell and 9b 35 insulating base having a flanged end portion e Conductors V provided an pen ng extending thqre- I Referring DOW t0 the figures Of the dIttY- through for electric conductors and having gs, 10 r presents as a whole th el t th d d h k ti id d ith a connection plug wlnch includes an insulatrecess in which are located and secured to mg base 11 Which may be formed of porce- 40 th b t contactmembers d t d t h lain or ot-her suitable insulatingmaterial and connected respectively tothe two electric comprlses a flanged end portion 11*, which conductors, "ne of the contact members hav- 18 preferably knurled on 1ts cylindrical face. ing a "or-tion projecting laterally outward and'a shank portion 11 which 1s threaded from t e' side of the recess and the other On ts exterior. The flanged end of the base 45 having a portion projecting in a 'ub t nhas an opening 12 extending therethrough tially radial direction from the end of the for the terminals of electric conductors 13 recess, and a threaded sleeve or shell which and the shankportion has a recess 14 Wl110l1 is screwed onto the shank portion of the base asshown communicates with the opening 12, and is provided at its outer end with an inand 1s open at the end and side of the shank, 50 sulated disk which is preferably'cemented and has opposite the open side an inclined to the sleeve, the parts being so arranged wall. Secured to the base in said recess by that when the sleeve is placed in normal poscrews 15 are two contact strips or members sition on the shank, the inner end of the 16 and 17 to which the ends of the electric sleeve engages the laterally projecting porconductors 13 which extend through the 35 tion of one of the Contact members, and the opening 12 may be connected in any suitable inner face of the insulated disk enga'ges the manner, but preferably by screws 18. It
will be seen that the. contact member 16 -1ssecured to the base at the bottom of the recess and'that its outer end projects outwardlyor laterally a short distance beyond the open side of therecess. It will be seen also that the contact member 17 is secured to the face of the inclined wall and that this contact member has a portion 17 in the form of a finger which projects outwardly fromthe open end of the recess, the end of this portion 17* projectingin a radial direction centrally ,of the plug. member 17 is made of material such that the finger 17 has some elasticit-y or' spring for a purpose-to be seen presently.
Fitted on and in this case screwed onto the shank portion 11 of the base is a threaded sleeve 19 which forms one of the contact members adapted to cooperate with a suitthe cement at the inner side of the disk and opposite or in line with the center of the plug is removed, as shown, so as to expose 'the central portion of the inner face of the disk. 4
When the sleeve is screwed to normal position onto the shank portion of the base,
the inner end of the sleeve engages the outwardly projecting portion of the contact member 16, and at or about the same time the inner face of the disk 20 is brought into engagement with theend of-the projecting portion 17 of the contact member 17. before stated, this contact member 17 hassome elasticity or spring, so that when the sleeve is placed in normal position onthe shank of the base, the end of the contact member 17 engages with considerable pressure the inner face of the disk 20. Thus, it will be seen that the shell is electrically connected to the contact member 16 and to one of the current carrying conductors 1 3, and
that the disk 20 at the end of the plug is electrically connected to the contact'member 17 and to the other current carrying conductor 18. v
It will be apparent from an inspection of the figurescf comparatively'few parts are here employed. Not only is the 'bb'nstruction which I have here shown much simpler in' comparison with those which have been used heretofore, but it'is considerably cheaper to manufac-' can be very This contact,

Furthermore,
the recess in the shank portion of thebase,
together with the shell which to the'base, form a protecting casing for the conductor terminals, tact members to which the conductors are secured.
I do not desire to be confined to'the exact details shown, but'aim in my claims to cover all modifications which do not involve a departure fromthe spirit and scope of my invention.
hat I claim as new and desire to secure by Letters Patent is:
