ELECTRICAL CONNECTOR.

To ZZ 'le/wm 'it may concern Be it known tllat I, ILlltonoj Sinus. va

citizen of the United States, residing at Chicago, in the county of. Cook-and Staterof Illinois, have invented certain new alld useful Illlprovelnents ill .Electrical Connectors, of wllicll the following is a full, clear, condescription, reference being had to the accompanying drawings, forllling a part ot this specification.

My invention relates to electrical eonnec tors, and '-lllore particularly to devices adapted to serve as the terlllillals ot electric conducting wires as connected witll binding posts or bolts` ot electrical gellerator or trails- My invelltioll relates lllore specifically' to that class or kind o'electrical connectors wllicll are adapted to embrace or surround the ends ot conducting wires, the insulation surroundingl the wires, it' 'such is carried byl the same, being stripped so as to allow the connector to engage' the wire. It has beell colllllloll ill the past to secure the connector or otllerl conlplicated and expensive methods. i

The object olf llly invention is tov provide nl lans ill connection witll a collnector of tllis classl which lllaybe clleaply alld eliectively connected to a conductor wire without the solder or expensive lllealls used ill connection with the. prior devices.

lll general the. device ol llly prises a. cylindrical portion adapted to elllbrace the wire to which it is to be, connected. A tongue is punched from the wall ol this cylindrical portion alld extends inwardly through a loop ill the conductor wire which is thus formed so that removal of said wire is prevented. rlhe usual form ol' ring` is provided at the upper elld oi' the cylindrical portion so that collllectioll lllay be easily lna-de to binding posts, etc.

My invention will be lllore clearly understood by reference to the acc(llllpanyilng,` drawings ill which:

Figure 1 illustrates ill elevation the connector ol llly invention. Fig. 2 is a longitudinal cross-sectional view ot' the same, this view being taken alollg the lille 2 2 of Eig. l alld looking'in the direction indicated yy'the arrows. Fig. 3 is.all elevational view of the electrical connector showing the conductor wire looped within the same, the connector ill this ligure being shown ill its nonillvelltion coul- Applieation filed January 2s, 1915.

closed position. Fig. l is an elevational view ot the connector alld conductor wire sllowll `in connected relation, the longitudinal portioll of the connector being closed so as to entirely inclose the conductor wire, alld Fig. i provided lllodilied form ot' terminal piece.

Similar'reference characters refer to similarparts throughout the several views.

The connector ot' llly invention is preferably lnade ot brass or copper, and eolllprises a ring portion 5 and a cylindrical portion (3. As clearly sllowll ill Fig. l, the cylindri al portion 6 is llorlllally open so as to adlnit the conductor wir Stalllped trom material ill the back of the connector is a tongue? which extends upwardly and inwardly ill all oblique direction, as most clearly shown ill Fig. 2. The upper elld ot' the cylinder (i is flared outwardly at 8 and S) so as to accolnll'lodate the loop ofthe collductor wire as will be presently described.

The, method oi connecting the device of uctor wire is 'as tollows: lhe conductor wire 10 is stripped of insulation, as illustrated ill Fig. 3. This conductor is shown as being solid in this ligure but it will l'eadly be understood that a conductor composed ol strands may be used equall' as well. After the insulation has been removed `from the end of the collductor l() the wire is inserted into the cylindrical portion (l alld t'ornled into a loop at l1 between the iared portions S and 9 aroulld the upwardly extending tongue 7, alld thence down ill the cylind-lr o, the edges of the cylinder (5 being then pressed ill` wardly until they assume. the position indi` cated ill Fig. 1t. It will readily be seen that the collductor wire 10 will then be tightly held agaillst renloval due to the engagement ot' its loop with the tongue 7.

lll the modification illustrated ill Fig. 5 the split cylinder is shown at o, the con ductol at 10, alld the terlllinal piece at 5, This terminal piece is cutawlrT at 15 so that the. terminal may he inserted around the stud of the binding post without removing the nuts usually carried thereby. rlhe terminal piece. may be provided with a slit 1G allowing the arnls ot' the terminal to tightly engage the stud of the binding post.

It will readily be seen that any form of terminal piece may be llsed ill conjunction with a with the split cylinderv Without departing of the sheet of material arranged to hold a conductor, said tubular portion being arranged to envelop the tongue and the porvtion of the conductor around the tongue to securely hold the conductor in place.

, In Witness whereof, lI hereunto subscribe my name thisv 25th day of January, A. D. 1915.
