Specification of Letters Patent.
Patented Feb. 2*?, MHT.
Application filed July 22, 1916. Serial No. 110,644.
To all whom @'15 may concern.:
Re it known that T. lons C. LivcoLN, a citizen of the United States of America, residing at Cleveland` in the county of Cuya hog'a and State of Ohio, have invented cer tain new and useful Improvements in illectrode-llolders, of which the followingY is a specification.
My invention relates to improvements in elect-rode holders of the type especiall)v adail ited for electric welding. in devices of this character it is necessary frequently to renew the carbon electrode or pencil when carbon is employed as the arcing` electrode: moreover7 the carbon rod by reason of its resist ance and subjection to the heat of the electric are becomes intensely hot. a result it is a common experience that the metallic parts of the carbon holder are partially destroyed by the intense heat and the electrical contact soon becomes very poor. it is necessary, of course, to employ a conductor for conveyingl the arcing currentto the carbon electrode, hence, the ordinary means for effecting heat and electric insulation are not available.
Moreover, the gripping mechanism preferably should be operative rearwardly of a suitable protective. shield for safeguarding and the electrode itself preferably is positioned at a convenient distance from the hand, so that the. radiation of heat will not be excessive.
My invention contemplates the provision of suitable conductive gripping jaws for the electrode. which preferably are of carbon and afford a sutlicient body for the flow of the electric current to prevent excessive heating. Moreover, the lever controlling these gripping jaws is electrically insulated and its finger-piece is extended through a protective shield provided .for the hand of the iis/er.
The features of my improvement will be more readily understood by making' reference to the accompanying drawings wherein Figure l is a longitudinal sectional view of my improved device; Z an enlarged fragmentary view of the socket for receiving the carbon jaws above mentioned; Figs. 3 and are similar fragmentary views illustrating the mode of inserting and removing; the particular spool-shaped and subdivided carbon jaws herein set forth; Fig'. 5 is a plan view of the complete device, and Fig, (i illustrates one of the carbon jaws., Throughout thel several figures of the drawings T have employed the same character of reference to indicate similar' parts.
The tubular member Vi'ornis the frame or shank of the devicer` rearwardly ol' which is positioned a wooden or other insulatingy handle in and at its opposite end there is provided a casting o, such as is shown in 2. This castingr is formed with a transverse socket or openingr one-half (0') of which is of less radius than the other half (r/lh as is shown in the plan view. The diameters of the semi-circlesA describing the respective socket portions are positioned at an angle of approximately forty-live degrees with the axis of the casting, the purpose o f which is to afford a ready means for insert-ing and removing" the carbon jaws.
These jaws (d, c) preferably are vertically subdivided and together approximate a spool-shape, centrally cored at f to accommodate the carbon electrode g. The flanges d c' of said jaws are approximately of the same radius as the portion c of the socket so that they will slip thereinlr while the semicylirulrical body portions d e of said jaws are approximately equal to the radius of the socket portion o.
Fig. 3 illustrates the manner in which one of these semi-spool-shaped members may be inserted in the socket and upon suitably turning and inserting the second member they are positioned as shown in Fig. si, whereby their respective flanges serve to hold the jaws in position within the casting. stout spring L is positioned interiorly of the tube a. and handle and reacts through rod i and its plunger i firmly to grip the jaws and electrode within the casting. A trigger extending through slots in the tube a. andpivoted to the rod i has an insulating iingerpiece j which extends through an opening provided in the nonconductive shield r secured to the handle. Current is supplied to the implement through an .insulated conductor Z and its screw plug Z forms the stationary abutment for the spring h.
lilith an understanding` of the structure just described`r it is seen that the electrode is adapted to receive current throughout the engaging inner faces of the carbon aws and the resistance of these jaws is so small that they will not become exees'vely heated by the i'iow of the maximum current,
Tn consequence` the metal parts oi the iniplement are protected from deterioration.

caf-l llforeover, the white hot electrode, when in use, is forcibly gripped by the jaws through the action of the spring and plunger and excellent electriccontact is insured within the implement itself, despite the fact that the,
sitioned iuteriorly of the handle, where it unaffected by the intense heat.
Hai/'ing now described the preferred embodiment of my invention, l claim as new a Ad desire to secure by Letters Patent the following i. in an electrode holder, the combination with a handle member, of a socket supported thereby, a renewable lining of conductive material therein, an electrode or terminal and means for adjustably holding said electrede within the lined socket, substantially as set forth. I
Q. ln an electrode holder, the combination with a handle member, of an electrode receptacle carried thereby, a conductive body within said receptacle and engaging the eleotrode, a suitable electrode, and means for gripping' the electrode and removably holding it within said conductive body, substantially as set forth.
3. in an electrode holder, the combination with a metal socket, of a subdivided carbon facing for the interior of the socket, a carbon electrode positioned interiorly of the facing and gripping means acting upon the carbon members, adapted to hold them in electrical contact within the socket, substantiall)7 as set forth.
t. in an electrode holder, the combination with a tubular handle, of a socket-member carried by the handle and adapted to receive the electrode, a movable part adapted to grip the electrode within the socket, a spring positioned interiorly of the handle and acting upon said part, and a trigger associated with the handle and adapted to relaxthe relates verse bore, of semi-cylindrical carbon menr bersloosely fitting within said bore; the same being centrally cored out to afford extended contact surfaces, a carbon electrode therein, and means acting within the receptacle for gripping the carbon members tightly about the electrode, substantially as set forth.
7. ln an elect-rode holder, the combination with a metallic holder, of renewable carbon contact-making jaws, a carbon electrode positioned therebetween, and retractile means for adjustably gripping the electrode between the jaws, substantially as set forth.
8. ln an electrode holder, the combination with a tubular shank, of a lgripping member adapted to removably hold the carbon or electrode, a handle positioned at a distance therefrom, a shield beyond the handle, centrally slotted, and a finger-piece extending through the slotted shield and connected to actuate the gripping member, substantially as set forth.
9. ln an electrode holder, the combination with a tubular insulating handle, of a spring therein, gripping means for the electrode at a distance from the handle actuated by the spring, a shield associated with the handle, and a linger piece positioned rearwardly of the shield for controlling the gripping means, substantially as set forth. i
