ELECTRICAL ATTACHMENT-PLUG.
Specification of Letters Patent.
Patented Feb. 8, 1921.
Application filed November 23, 1917. Serial No. 203,618.
To all to 710m it may concern:
Be it known that I, J ()HANN (,i. ln'rnnsorz, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Electrical Attachment-Plugs, of which the following .is a, specification.
This invention relates to electrical attachment plugs, the object of the invention being to provide an article of this character which is simple in construction, quite compact, and by which the. wires or other leads can be connected to their terminals in a simple and ready manner.
In the drawings accompanying and forming part of the present specification l have shown in detail one convenient form ofembodiment of the invention which I will set forth fully in the following description to enable those skilled in the art to practice the same. I do not restrict myself to this particular disclosure; I may depart therefrom in severalrespects within the scope of the invention defined by the claim following said description.
Referring to said drawings: 7,
Figure 1 is an elevation of an electrical attachment plug involving the invention.
Fig. 2 is a vertical sectional view of the same.
Fig. 3 is a bottom plan view.
Figs. 4 and 5 are transverse sections on the lines 4. and 5 of Fig. 2, looking respectively downward and upward.
Like characters refer to like parts throughout the several views.
The device comprises in its construction a body or core such as that denoted in a general way by 2. This part is usually made of insulating material such as porcelain or composition, and is virtually of cylindrical form after the custom. Said part 2 includes preferably a main member as 3 and an auxiliary member as 4, these being associated together in a novel manner when the plug is organized for connection with an incandescent lamp socket such as that of the well-known Edison type. The main section 3 of the body is surrounded at its lower end by the contact shell 5 which is usually threaded to fit the type of socket mentioned. This contact shell 5 is flanged as at 6 to overlie and fit fiatwise against the inner end of the main member 3, The flange 6 has the elongated slot 7, the ends of which may as shown be rounded. This slot 7 is in register with a cavity or chamber as 8 which in the present case is shaped longitudinally to conform to the slot 7. This chamber or cavity I might also observe constitutes a keyway and the slot 7 aids in this particular office.
The auxiliary or cap member 4 of the body has on its inner side the projection 9 which in longitudinal configuration corresponds to the slot 7 and chamber 8. This projection acts as a key, and when the parts 3 and 4 are in assembled relation as shown for instance by Fig. 2, the projection 9 obviously enters the slot 7 and chamber 8 and thus effectually prevents accidental relative turning movements of the parts 3 and 4. These parts, however, are held in assembled relation by other means, the screw 10 being shown for the purpose. The head of the screw fits a counterbored opening in the disk 11, fitting somewhat freely the cavity 12 centrally of the outer face of the part 4.
The main member 3 has the chamber or opening 18from which the branches let and 15 extend, said opening with its two branches extending the entire length of the mam member 3 and being intended for the passage of the wires 16 and 17 The branch opening 15 when the parts are in assembled relation coincides or registers with an opening 18 through the auxiliary body member 4 and intersecting the cavity 12 to-which I have already referred. portion 19 of the main member 3 has for example molded therein the nut 20, the outer end of which is approximately flush with the bottom of the cavity 8. This nut 20 has its longitudinal axis coincident with the longitudinal center line of the plug and is intended to receive the threaded part of the screw 10 to thus hold the main and auxiliary members 3 and 4 in assembled relation. The screw 10 in addition to acting in the manner set forth also constitutes a part of the central end contact, its head 10 and the disk 11 acting to obtain this function, it being clear. of course, that the outer face of the head and disk are flush and central of the auxiliary part 4.
While the head of the screw and disk 11 serve as a central end contact, the lateral contact is provided by the shell 5. to which one of the conductors as 16 is electrically connected, the other conductor being elec- The web or central trically connected wlth the screw 10 and (llSkl circular body or flange 25 which may partly 11. The flange 6 of the contact shell has i an opening or perforation tor the passage of the screw 21, the main member 3 of the plug having embedded therein a nut 22 to receive the screw 21. The branch 14- of the opening 13 is in register with a hole or perforation 23 in the flange 6, thus to provide for the proper connection of the wire 16 with the shank of the screw 21, the bared or skinned part of the wire being pressed into electrical connection with the shell 5 by said screw 21.
It will be supposed that it is desired to connect wires as 16 and 17 with the plug. In this case the following procedure may be adopted: The screw will be taken out or wholly disconnected from the nut 20, so thatthe part4 can be separated from the part When this is done a wire as 16 will be passed through the opening 13 and its branch 1 t and its bared or skinned end will be wrapped one or more times about the shank of the screw 21, following which the screw will be run in to bind the bared wire against the flange 6 of the contact shell. The other wire 17 will then be run through the opening 13 and its branch and 'its end bared or skinned and then wrapped one or more times about the shank of the screw 10. The projections 9 will be then seated in the slot 7 a and chamber 8 until it virtually bottoms in the-chamber at which time the screw 10 will be connected with the nut 20. The auxiliary member at may as shown have a depression 24 to receive the screw 21 when the parts are connected. As shown the flange 6 has a part surround the wire coiled about the screw 21.
l/Vhat ll claim is:
An electrical attachment plug comprising auinsulating body having a main and an auxiliary'section, a contact shell around the main section and flanged over an end thereof, the auxiliary section being fitted against the flange of the shell, the main sectipn of the body having an oblong cavity disposed 'adially thereof, and the walls of which are parallel, the flange of the shell having a slot of the shape corresponding to andin register with the cavity, the auxiliary section having a projection corresponding in shape with the cavity and the slot, extending through the slot and into the cavity, a central end contact fitted against the auxiliary section, a disk, the auxiliary section havingm cavity to receive the disk, a nut embedded in the main section, a screw through the disk and the auxiliary section and threaded into the nut for fastening a wire to the central end contact, a screw tapped into said flange, the flange in turn having a flange to partly surround the wire coiled about said second screw, the first flange having an opening for the passage of the second wire.
