2 Claims.

This invention relates to an electrode holder, the general object of the invention being to provide means whereby an electrode can be easily and quickly seized by the jaws of the holder and without danger of' the operator receiving a shock, with spring means for causing the jaws to grip the holder.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is an elevational view of the invention.

Figure 2 is a top plan view thereof.

Figure 3 is a section on the line 3-3 of Figure 2.

Figure 4 is a section on the line 4-4 of Figure 2.

Figure 5 is a section on the line 5-5 of Figure 2.

Figure 6 is a view looking toward the inner face of one of the jaw members.

In these views the numeral I indicates'a pair of jaw members having inwardly extending ears 2 intermediate their ends which are pivoted together as shown at 3. A pair of handle members 4, each of semi-circular shape in cross' section, receive the inner ends of the jaws with the jaws suitably connected to the inner parts of' the handle members and a spring 5 is placed between said inner ends of the jaw members for pressing the inner ends apart to make the gripping ends grip an electrode 8 between them. One of the jaw members is formed with a socket 1 for receiving the stripped end of a conductor 8 and the side edges of the two handle members overlap as shown at 8 in Figure 5 and overlapping plates III of non-conducting material close the inner end of the handle members, see Figure 4, so

that objects cannot enter the handle parts to interfere with the operation of the device. The

outer ends of the jaw members are flat as shown at H and the inner face of each flat part is provided with a plurality of grooves H, see Figure 6, which lie closely together and some of the grooves extend parallel and transversely of the jaw member while others extend diagonally as also shown in Figure 6. By placing the grooves close totrode in the grooved part so that when the jaw members close they will grip the electrode without requiring the operator to lose any time in placing the electrodes between the jaws.

Thus it will be seen that the operator can easily and quickly cause the jaws to grip an electrode or other object and then by relieving pressure on the handle parts th spring 5 will cause the jaw members t firmly grip the electrode. By making the parts of non-conducting material there is no danger of the operator being shocked and preferably the jaw members are covered with non-conducting material so that current cannot pass from the electrode to the operators hands.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claims.

Having described the claimed as new is:

1. In a device of the class described, a pair of elongated jaw members, inwardly extending ears on the intermediate portions of the jaw members pivotally connected together, handle members each of substantially semi-circular shape in cross section, connected with the inner ends of the jaw members, a spring located between the inner ends of the jaw members and moving the outer ends of the jaw members toward each other, the side edges of the handle members being reduced in thickness and the side edges of one handle member overlapping the side edges of the other handle member.

2. In a device of the class described, a pair of elongated jaw members, inwardly extending ears on the intermediate portions of the jaw members pivotally connected together, handle members each of substantially semi-circular shape in cross section, connecmd with the inner ends of the jaw members, a spring located between the inner ends of the jaw members and moving the outer ends of the jaw members toward each invention, what is other, parts at the side edges of the handle members overlapping and plates of non-conducting material connected to the inner ends of the handle members and located between adjacent parts of the jaw members with the inner side edges of the plates overlapping.

gether it is simply necessary to place the elec- RUPERT R'. REDDICK.
