AIR" COOLED ELECTRODE HOLDER Filed Nov. 1, 1945 Inventor Iouz's 2.145%37725072 I Attorneys Patented May 4, 1948 UNITED STATES PATENT QFFICE AIRFCOOLED ELECTRODE HOLDER Louis D. Abramson, Boston; Mass; Application November 1, 1945, Serial No; 625,992
. 1 Claim. 1
My invention as described herein, and. illustrated inthe accompanyingodrawings, consistsof an electrode holder for use in electric welding operations, an object of which is to provide means for dissipation of the great heat generated in the holder.
Another object of my invention is to provide an air cooled electrode holder.
A further object of this invention is properly to seat in the holder electrodes of various diameters.
A still further object of the invention is the provision of means whereby an electrode of any diameter may be instantly and securely gripped through a part turn of the holder handle.
Other features and advantages will become more readily apparent from the following description and the accompanying illustrative drawings in which:
Figure 1 is a longitudinal sectional view of my holder,
Figure 2 is a section on line 2-2 of Figure 1, the electrode removed,
Figure 3 is a detail of a jaw actuating sleeve, and
Figure 4 is an elevational View of an electrode gripping device shown attached, the handle partly broken away.
In the accompanying drawings, and in the following specification, the same reference characters are used to designate the same parts and elements throughout and in which it, refers to my invention in its entirety and H, indicates a housing which is provided with numerous periorations 2, for free circulation of air into its chamber l3. Mounted within the chamber I3, is a sleeve M, the inner end l5, of which is of a diameter to snugly seat within the chamber l3, and the lower edge l6, of which extends somewhat below the annular guard flange l'l, provided on the lower part I8, of the housing l I, whereby screws 99 and 2B, threaded through bores 2i and 2.2, of said guard and wall 23, of the casing and into threaded bores 24 and 25, in the enlarged it, of the sleeve l4, whereby the sleeve will be held in fixed position. The wall 25, of the said sleeve is provided with a series of annularly disposed perforations 21, and interposed longitudinal slots 28.
the upper end 29, of the sleeve 14, is pro vided a conical recess 30, into which is slidably movable the clamp head 3|, of a similar conical formation extending from the arm 32, which arm and head are divided into three sections 33, 34 and 35, by longitudinal slots 36, 31, etc, and are 2: integrally connected at 3B, adjacent screwthreaded enlargement 39, of-the arms The enlargementlE, of the-sleeve i l, is internally screw threaded as at 40; to receive the screw through means of which the jaws ii, 42 and 43, of the head 3|, may be moved back and forth in the conical recess 30. The arm end 32, is graduated in diameter as at M and 45, whereby the latter enlargement forms a plug for projecting into the bore 45, of a tubular handle and is fixedly secured therein by a screw 38. The end 459, of the handle containing the enlargement 45, seats movably within the terminal end of the housing I l.
From the part 38, out to its terminal 5!, the arm 32, is bored in graduated diameters from the smaller inner bore 52, to form gradually increasing seats 53, 55, 55, etc., for the ends 56, of electrodes 5?, whereby one electrode of any diameter may readily find its proper seat when projected through the bore 58, in the end wall 59, of casing ii, and the openingfill, within the recess 39, in which head 3|, is movably seated. A conductor cord 61, extends through the bore 46, of handl ll, and has its exposed terminal wires 62, soldered into the bore 63, of plug 45.
The casing ll, guard flange H, and handle G7, are all formed of non-conducting insulation. The other elements of the device, however, are electrodes for conveying electric current from wires $2, to the electrode 57. Upon giving the handle ll, a quarter turn relative to housing I l the jaws ll to 43, may either be clamped upon the terminal end 56, of the electrode or upon reverse turn of the handle slightly withdrawing head 3i, from the recess 39, the jaws will spri 10086 from said end 56, and release the member iii, to be dropped from the tool.
From the foregoing it will be seen that I have designed an electric welding tool which through means of the several air circulating chambers l3, and 55, will dissipate the heat generated in the holder before it reaches the handle 47, and also a tool with which electrodes of various diameters may be instantly grasped and released.
It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considerin the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.
Changes in shape, size and rearrangement 01 details and parts such as come within the purview of the invention claimed may be resorted to, in actual practice, if desired.
Having now described my invention, that which I claim as new and desire to procure by Letters Patent is:
A holder for a Welding electrode which includes a tubular handle of non-conducting material, a. plug of conducting material fitted into one end of said handle, said plug having an axial bore entering into its inner end for receiving one terminal of an electrical conductor, an integral shank extending axially from the opposite end of said plug, an integral externally screw-threaded collar on the shank intermediate its ends, an annular row of internally stepped welding rod clamp jaws projecting from the end of the shank opposite the plug, enlargements on the free ends of the clamp jaws cooperating to form a substantially conical head, a perforated sleeve of conducting material encircling the clamp jaws in spaced concentric relation therewith, said sleeve having a conically tapered bore adjacent one end for receiving the conical head, an internally screw-threaded socket on the end of the sleeve opposite the conical bore for threaded engagement with the threaded collar, a perforated tubu- REFERENCES CITED The following references are of record in the file of this patent:
