Application filed August 3, 1908. lSerial No. 446,562.

To ali whom it may concern.'

Be it known that I, HARRY GLENN WEEKS, a lcitizenfof the United States, residing at Pittsfield, in the county of Berkshire, State of Massachusetts, new and useful Improvements in Connectors for Electric Conductors, of which. the following is a specification.

This invention relates to means for connecting electrical conductors and has for its object the provision of aI device of this character whereby the circuit connections may quickly made` and broken in a simple and etlicient manner. In the accompanying drawing, in' which s I have "shown my invention embodied in concrete form, Figure 1 is an elevation partly in section of one member of my connector; Fig. 2 is an elevation vof the other 2o member; Fig. 3is an end view of the device shown in Fig. 1 ig. 4 is a similar view of the member shownjin Fig. 2; and Figs. 5 and 6 show the two positions of my ,device with the circuit connections made in 2.5 each case.

Referring to the one member of my connector which may be called the plug member, and.` 11 represents the cooperating or socket member.` .These two members are adapted to.be connected together in two positions so as to obtain 4two dilerent arrangements of the circuits. In the device I have shown, the member 10 is the one which is usually fixed while member 11 is `connected to the source of current and is shifted. The member 10 consists of a block of insulation in which are embedded: thectwo single plug terminals 1 2 and 13 provided with binding screws 14 4D and 15 respectively. The third plu 16 .is likewise mounted in the block o` insulation in line with the other two so that the plug 13 is intermediatethe other t-wo. -This plug issurrounded by 'a cons ducting sleeve 17 from which itis separated by an insu spaced from the plug 16 "at its inner end so as to permit the socket to fit between the two parts.- Binding screws 19.an d 20 are arranged for making circuit connections A to these two parts. The member 11 lis a block of insulating material preferably made lin halves as shown and held together by screws. This block of insulatingmaterial 1s provided withthree apertures 21, 22"and;

have invented certain drawing, 10. represents lating sleeve 18. This sleeve isv 23, all opening into a common aperture 24 through which the cord containing the electr1cal conductors is brought. In two of these apertures are placed socket terminalsL 25 ,and 26 connected with the conductors 27. The particular'design of theseterminals forms no partiof my invention and need not, therefore,I be describedin` detail.' The socket portion simply consists 'of split tubes adapted to fit over 'the plug terminals, so as to makea good electrical joint. The aperture for the socket 25 is enlarged at 28 so as to permit the sleeve 17 to pass over the socket while the plug 16 enters the socket. In this way the socket 25 makes electrical' connection with both the plug 16 and the sleeve 18. With this arrangement it will be seen thatl when the two parts 10 and 11 are connected, the plug 13 always enters the socket 26, but the plug 12 is adapted `to enter either the socket 25 or the aperture 21, while the plug 16 and sleeve 17 are likewise -adapted to enter either of the apertures 21 or 23. This is accomplished by simply turn-` ing one of the other members, as `for instance member 11, through 180.

In Figs. 5 and 6I have shown mydevice in connection with coils, which may be coils of a heater. In heating'devices it iS frequently desirable that the circuits be arranged so that two or more heats may be-employed, and for ,purposes oi illustration I have Ashown my connector with this type of device. In these figures R and Rf represent; the two heating coils,which are connected to the mains L and L. In Fig. 5 the two parts 10 and 11 are placedtogether in theLrelative positions shown in Figs. 1 and 2, so that the resistances R and R are connected in par-v allel. The current passes from the line to socket 25, plug 16, resistance Rf and back ile I have shown my invention in con` vtr spo

ating in a definite manner, it should be understood that I do not limit my invention thereto except in so far as it is limited by the scope of the claims annexed hereto.

What I claim as new and desire to secure by Letters Patent ofthe United States, is

l. A connector for electric conductors comprisinga member having two circuit terminals arranged for connection to Ja source of current, and a coperating member havingthree terminals7 two of which are insulated from each other and simultaneously engage one of said cooperating terminals.

2. A connector for electric conductors comprising a member having four terminals, two of Whichare adjacent and insulated from each other, and a cooperating member having two circuit terminals one of which is arranged to engage either a single coperating terminal or the two insulated terminals simultaneously.

3. A connector" for electric conductors comprising a member having two single terminals and a double terminal, and a coperating member-` having two terminals one of which always engages one single terminal While the other engages either the other single terminal or the double terminal.

4. A connector for electric conductors comprising a casing having three apertures, two of which contain circuit terminals, and a cooperating member having three terminals so arranged as to enter the apertures and engage the two terminals.

5. A connector for electric conductors comprising a casing having three apertures, two of which contain circuit terminals ar- ;ranged for connection to a source of current, l

and a coperating member having three terminals, one of wlnch'is double'and so arranged as to enter the apertures and engage.

ranged for connection to a source of current,

and a coperating member having three plug terminals arranged to enter the apertures to engaee the sockets, one of said plug terminals Iiaving an independent connecting portion insulated from the main terminal.

8. A connector for electric conductors comprising a casing having three alined apertures, socket terminals within two adjacent apertures arranged for connection to a source of current, and a cooperating member having three plug terminals similarly arranged to enter the apertures and engage the sockets, one of the end plug terminals having an independent connecting portionl insulated from the main portion to form two parallel circuits.

In witness whereof, I have hereunto ,setmy hand this 81st day of July, 1908.
