To aZZ whom it mag/0011mm:

' Be it known that ll, CHARLES A. DEUsoHER,

' a citizen of the United States, residing at Improvements in Connectors, of which the I following is a specification.

This invention relates to a connecter.

The connecter to which the invention more particularly relates comprises a conductor by which a resistor of an electric heater ma be connected to a terminal thereof.

11 object of the invention is to provide an improved connecter.

Another object is to provide a connecter which may be firmly and rigidly connected with a resistor or other conductor.

Another object is to provide a connecter which when joined to a resistor will not be loosened when heated repeatedly.

Another object is to provide a connecter so connected to a resistor and having such inherent characteristics that the terminal to which the connecter is connected ismaintained at a relatively low temperature.

Another object is to provide an improved connection between a resistor and a connecter.

Another object is to provide a strong and durable low resistance connection between a resistor and a connector.

Another object is to provide a connection between a connecter and a resistor which will not work loose under repeated wide fluctuations in temperature.

Another object is to rovide a connection between a resistor an a connecter which will not be affected by high temperatures.

Another object is to provide an improved method of joining a conductor to a connecter.

Other objects andadvantages will hereinafter appear.

The views of the drawings are: I

Fig. 1 shows a connecter blank in the form of a rod;

Fig. 2 showsthe connecter blank with one end flattened;

Fig. 3 shows the connecter with the flattened end twisted to form a groove therein;

Fig. 4 shows the connecter with the end of the resistor arranged in the groove thereof;

Fig. 5 shows the connecter with the Specification of Letters Patent. P b t m, m, 1922 Application filed October 2, 1920. Serial No. Q4380). I

grooved end thereof ,partly contracted on \the entwined resistor; and

Fig. 6 shows the connecter with its grooved end contracted into intimate contact with the entwined resistor.

The connecter may be made of any suitable metal or alloy and of such cross section that it is rigid and the conductivity thereof s greater than that of the resistor which it 1s to connect to-a terminal. A connecter of nickel-copper has been found to be suitable for this purpose.

- The connecters are in%manner:

lanks 1 of the required length and in the form of rods are provided.

One end of the rod is flattened.

The flattened end 2 is then twisted to form groove 3.

formed in the follow- When a helical resistor 4 is to be joined to a connecter, the helices at the end 5 thereof are first stretched out and then arranged in one of the grooves 3 of the connecter. The connecters may, of course, be employed to corlinect other kinds of conductors to termina s.

The grooved end of the connecter is then hammered, swaged or otherwise contracted crosswise whereby the entwined end of the resistor is firmly gripped by the grooved connecter, and the resistor and connecter are in intimate contact.

During the process of contraction, the grooved end of the connecter is deformed so that it grips the entwined resistor. Thus the resistor and connecter are joined together in intimate contact, so that the connection therebetween is of very low resistance.

The resistor is wrapped around the connecter and is tightly gripped thereby, a

great proportion of the peripheral surface' sired, both ends may be grooved for connec tion to conductors or resistors.

The connection is strong and durable and is not affected by heat at the operating temperature of the heater.

The resistor forming the heating element of an electric heater may be subjected to he connectlon between the connector and: the resistor of such heaters should-be ableto fwithstand such high temperatures and such great variations'in temperature so that the heater may-be efiicient and of long life.

Among the advantages of such a connection between the resistor and the connector are the following: I,

It is of low resistance.

"It is durable. I f

It is highlyefiicient.

It is not afiected by high temperatures and wide variations thereof. v

The invention contained herein is of course susceptible of other .embodiments and adaptations. v

The invention claimed is 1. A connecter for connecting anelectric conductor to a terminalcomprlsing a conducting rod having a groove formed in-one end for the reception of the conductor and the other end arranged for connection to the terminal.

A connecter for connecting an electric conductor to a terminal compnsing a conductor having a spiral groove formed in one end thereof for the reception of the electric conductor, about which the walls of the groove may be forced into intimate contact.

3. A connecter for connectinga conductor to a terminal comprising a rod having a groove formed in the periphery thereof for the reception of the conductor, the connecter and entwined conductor being contracted crosswise into intimate contact.

4. The method of joining a conducto and a connecter which consists in arranging the ends thereof in complementary conformation and then deforming the engaged ends to bring the same into intimate contact.

5. The method of joining a connecter and a conductor, which consists in arranga connecter, which consists in arranging the I ends thereof in entwined relation and then .moaaoe one end thereof a groove in which the connecter contracted subjecting the. entwined ends to pressure tobring the conductor and, the connecter into M intimate contact.

7. The method 'of joining a conductor and a connecter which consists in arranging the ends thereof in entwined relation.. and then compressing the connecter about no and into intimate contact with the entwined conductor. I 8. The method of joining a conductor to a rod like connecter which consists in fiattening one end of the connecter, twisting the flattened end to form a groove therein, ar-

intimate contact with the conductor.

9. The method of'joininga conductor to a rod like connecter which consists/in flattening one end of the connecter, forming the flattened end to provide a groove therein,

arranging the conductor in the groove, and

subjecting the overlapping connecter and conductor to pressure to brmg the same into intimate contact. I a

the conductor overlapping one end thereof, the connecter being contracted into intimate contact with the conductor, the other end of the connecter being arranged for connection to the terminal.

12. A connecter'for connection to an electric conductor comprising a conducting rod having a groove formed in one end for the reception of the conductor.

13. A connecter for connection to an electric conductor havinga spiral groove formed in one end thereof for the reception of the electric conductor, about which the walls of 100 the groove may be forced into intimate contact. a

In witness whereof, I have hereunto subscribedmy name.
