Dec. 24, 1946. w. E. CARDINAL ELECTRODE HOLDER Filed Aug. 50, 1944 Ill-l 11:525., s v v llllllfill'wlll d/M/Mm f 62/72 074? Patented Dec. 24, 1946 UNITED STATES PATENT OFFICE 1 Claim.

The present invention relates to new and useful improvements in electrode holders and has for its primary object to provide a pivotally attached head section on a handle section whereby the welding rod carried by the head section may be moved into a desired angular position with respect to the handle, or may be held in a position extending longitudinally thereof.

More specifically, the invention embodies a handle section and a head section hingedly connected thereto, said sections including insulation sleeves and each of said sections including connectors between the respective sections hingedly 7 connected to each other within one of the sleeves and including sockets adapted for receiving respectively the electric cable and the welding rod.

A further object of the invention is to provide a device of this character of simple and practical construction, which is efiicient and reliable in use, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which- Figure 1 is a side elevational view.

Figure 2 is a top plan view.

Figure 3 is an end elevational view.

Figure 4 is a longitudinal sectional view.

Figure 5 is a bottom plan View with parts broken away and shown in section.

Figure 6 is a bottom plan view with the head section shown at right angles to the handle, and

Figure '7 is a transverse sectional view taken substantially on the line l-l of Figure 1.

Referring now to the drawings in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates a tubular handle of insulation material having openings 6 formed therein and the numeral 7 designates the tubular head of insulation material and also having the vent openings 8 therein.

Positioned in the handle 5 at its front end is a cylindrical connector 9 of conductive material and separated from the handle by means of an insulation bushing lo, the connector being secured to the handle by set screws II which are also used to secure an electric cable (not shown) in the socket l2 of the connector, the cable being adapted for extending outwardly through the rear end of the handle. An insulation bushing I3 is also positioned intermediate the ends of the handle to prevent contact of the cable therewith.

The front end of the connector 9 is closed and terminates substantially in the plane of the front end of the handle and projecting outwardly from the front end of the connector is a fiat plate l4 inserted within a bifurcated extension l5 formed at the rear end of a connector it of conductive material positioned in the head I. The plate I4 is pivotally connected to the bifurcated extension l5 by means of a bolt and nut l 1 whereby to provide for the pivotal movement of the head relative to the handle.

The connector I6 is also separated from the head I by means of an insulation bushing I8 and the connector further includes a socket portion l9 adapted for receiving one end of the welding rod 20 secured therein by means of a bolt and wing nut 2| which may be threaded through openings 2| in either side of the head. A metal cap 26 is crimped over the end of the head i to protect the latter from sparks and is formed with an opening through which the welding rod is inserted. The connector I6 is held in the head by means of a set screw 22.

Also positioned in the head 1, outwardly of the connector I6, is an insulation collar 23 having a flared opening 24 aligned with the socket Hi to guide the rod 20 into the latter, the collar 23 protecting the connector [6 from injury by the arc of the welding rod when the latter is substantially consumed through use.

One side of the head 1 is formed with an opening 25 to provide access to the bolt and nut l1 to remove the head, when desired, or to bind the bifurcated extension 15 relative to the plate M to frictionally hold the head in its angularly adjusted position.

From the foregoing it will be apparent that the head 1 may extend longitudinally outwardly from the handle 5, or may be moved into a desired angular position with respect to the handle as shown in Figure 6.

It is believed that the details of construction and manner of use of the device will be readily understood from the foregoing without further detailed explanation.

Having thus described the invention, what I claim is:

An electrode holder comprising a handle section and a head section, said sections including sleeves of insulation material, a pair of sockets of conductive material enclosed in said sections and adapted to respectively receive a cable and a welding rod, projections on the sockets in one end of the sleeve included in the head section, and a pin pivotally connecting the projections to provide for the pivotal movement of the head on the handle, said pin being enclosed in the sleeve included in the head section, and an insulation collar in the other end of the sleeve included in the head section having a. flared opening therein for guiding the rod into the socket in said head section.

WILLIAM E. CARDINAL.
