To all whom it mat) concern:
Be it known that l, HOWARD tion.
invention relates to attachment plugs and the like such as are used for making electric circuit connections to sockets; and receptacles of various sorts, and-it comprises various novel features anddetalls' of. construction and comhinatlons and arrangement of parts that can best be presented by the description of a partlcular device embodying them in the best form} at present known to me. Many advantagesobtainable in connection with the invent1on-.w1ll 'ap; I 2@ pear from this description-,e'such as simplicity, neatness of -appearance,"ruggedness, 1 case and cheapness of manufacture. and facility of connecting up,.wh1le lts scope will;
be indicated in my claims. 1'
In the accompanying drawing jFigurej 1' is a mid-section through a' plug constructed" I in accordance with the invention lliig, 2 isf ,a tilted View of certain parts of the dey1ce-.- detached and separated from. the rest;- lhigsg 3 and 4: are tilted views of other parts, and- .'illustrate the wiring of the-device; Referring first to Fig.; ;:1, it will he 8 1 1;)? that the main structure oribody of the'p'lug comprisesxinsulating parts 1.a'nd,2 wh1ch.;-
are separate but are secured together," .'llhe' se arts may be made of .porcelain,; hisque Elmer, or any suitable insulating compound tended for sockets of the Edison screw type,
the electrical parts associatedwith the-hotlyinclude a screwcontact shell "3 around it.
, and a center contact t on one end. shown, the insulating part 2 fits within' the contact shell 3, and the-latter'hasffit up er end an inwardly bent flange portion (2 Fig.2) that extends between the parts 2; As a matter of practical manutac ture, the portion, 5 of the shell 3' cam-sot.
l anll course, he made as a punched out.' J l[t isohviously. necessary that the contact shell 3wshould not turn with reference-to; the insulating part 1 when the-plug is "being screwed into or outjof a socket, and itis much to be preferred that the insulating SAnGn 'r, a citizen of the United State s,flre'siding at Schenectady, county of Schenectady, State following ,is'a specificaa bottom with a pcrtibu have been pushed specification r eat-tam, a. ranted May 2, rate; Application an run at, ota semi no; etrnee.
paitffl shouldnet do soeither. While the I thelpart has a similarly shaped recess 7 in which this projection 6 engages. The edge 01E; thelflange 5 in part conforms to the jangular'side of, the projection 6, and along this edge-the metal of the flange is turned down at 8 sons to fit in the recess 7 between its; sides -and the corresponding sidesof said 'projeetion, and thus the portion 5 of theish'elldis-"engaged with each of the in Ill sulating parts 1 and 2 in a way,that eflec- .tua-llypreyents theshell from turning with reference to either of them. i
In the insulating part 1 is secured a'compos'ite metfal part 9 comprisin an exposed :portion that' lies in a depression in the end of th'e'project1on 6 anda sleeve portion lllthat lies in a central loore in said part 1 and is at its ends; @The hole or here of the sleeve se;cure 'd;in"place and connected to the ex 7 ;posedl portion by -loeing suitably expanded '(which liesin adepression in the-lower end I t the insulating part 2 extends through i the insulating part 2 and engages in the j. holeot'the sleeve 10, thus at once detachaloly securing the insulating parts together an iprojection'fi, while the hole 16 comes out 7 close 1llSQ ll)l18 diagonally, opposite corner of the projection 6. 'ln' theend :of the .pro-l ection. 6 at the opposite side of the exposedinsulatingpar't l, and in the main lower surthrough the holes 15 and win the main lower surface of the part 1 3 putting the'metal part 9 exposed between, them a s--ahove described in electrical cong. 'nectioni-with the center contact 4. I the upperside of the insulating m em'---- herl. is a recess-13 that receives the end or the insulated cord or cable 14, and from the .fib0ttomhtthisrecess holes 15 andlt extend ;'through' the part If to the ahuttingsurtaces at its11lower'side- Eds shown-the" hole ,15 'licomes out through the curved edge'ol the 16,the insulating parts 1 and 2 having previously been taken apart, of course, these ends are first bent transversely and then back into the holes 17 and 18 respectively. When the insulating'parts l and 2 portion 5 of the shell 3 and the abutting surface of the part 1. At the same time the portion 5 of the shell 3 is securely clamped and held. As the abutting surfaces of the insulating parts 1 and 2 between which the ends of the wires 19 and 20 lie are in diferent planes, the circuits are thoroughly well insulated from one another, especially as the edge of the flange 5 is some'distance from the curved side of the projection 6 where the wire 19. lies. i
What I claim as new and desire to secure by'Letters' Patent of the United States, is '1. In an attachment plug, the combination of a body comprising insulating parts secured together, a contact shell around said body having an internal flange between abutting surfaces -of;the parts, acenter con-.
tact associated with one of said parts, and
current leads extending through one of said parts and having their ends clamped between them, one in electrical connection with said center contact and the other with said shell.
a 2. In an attachment plug, the combination of a body comprising insulating parts secured together, a contact shell around said body having a portion bent inward between abutting su'rfacesin different .tact'shell around said body having an inter-Z 3nal flange between the insulating'parts, a
abutting surfaces of the insulating parts, a center contact associated with one of said in-.
sulating parts and ametal part exposed between them and in electrical connection with said center contact, and current leads extending through one of said insulating parts and having their 'ends clamped between them in contact respectively with said exposed metal part and with the shell.
3. Inan attachment plug, thecombination.
of a body comprising insulating parts se cured together and having a plurality of planes, a concenter contact associated with one of said insulating parts, and current leads extending through one of said insulating parts and -having their ends clamped between abutting that are in different planes, one in electrical connection with said center contact and the other with, said shell surfaces of said parts 4. In an attachment plug, the combination ofa body comprising insulating parts secured together, a contact shell and a center contact associated with them, and current leads extending through one of said parts and having their ends bent backward into separate holes in said part, portions of said leads being clamped between the parts in electrical connection withsaid shell and with said center contact respectively.
5. In an attachment plug, the combination of a body comprising insulating parts detachably secured together, a contact shell around said body having a portion bent inward between the insulating parts, a center Contact associated with one of said insulating parts, a metal part associated with the other of said insulating parts exposed between them and in electrical connection with said center contact, and current leads extending through the insulating part with which said exposed part is associated and having their ends bent transversely and clamped respectively between said latterina screw shell around the insulating part with the recess having between the insulating parts an internal flange engaged with one of them so as to prevent said shell from turning with reference to them, a center contact associated with the insulating part having the recess, a metal part exposed between the end of the projection and the bottom of the recess and in electrical connection with said center contact, and current leads extending through the insulating part with the projection and having their ends bent and clamped against said inwardly bent portion of the screw shell and said exposed metal part respectively. Y
7. In an attachment plug, the combination of a body comprising insulating parts interlocked so that they cannot turn with reference to one another, a screw shell around one of said insulating parts having between I them an inwardly bent portion so engaged that said shell cannot turn ith reference to the" other insulating part, a center contact associated with the insulating part around which is the contact shell, a metal part secured to the other insulating part and having a threaded hole and a portion exposed between the insulating parts, current leads extending through said other-insulating part and having their ends bent so as to lie against said exposed portion of said metal part and against said inwardly bent portion HELEN UBFORD.
