March 26, 1957 J. c. HONHART HOLDER FOR A WELDERS BRUSH Filed Jan. 11, 1954 T m NW 1 m v a i M m C MW M A J 2,786,221 HOLDER FOR'A WELDERS BRUSH Jack Charles Honhart, Detroit, Mich.

Application January 11, 1954, Serial No. 403,188 6 Claims. c1, 15-146 This invention relates to a welders brush holder. In arc-welding the electrode is held in a holder which is handled by the welder. The current is turned on, the welder touches the electrode to the work and then withdraws it a slight distance which initiates an arc. As long as he holds the electrode slightly spaced from the work, the hot arc is maintained. This arc melts the electrode and leaves a residue of metal on the joint that is being welded. It is desirable to chip this off and brush the chips off the Work. To this end I have invented a combined brush and chisel holder described and claimed in my prior Patent 2,368,988, February 6, 1945. This has been manufactured and sold in large quantities over the years following the filing of this application. I have found that I can now improve this tool in several respects which will make it more attractive and useful to the man that does the welding. The new design that I am here describing and claiming makes a stronger and cheaper tool. Referring to the drawings:

Fig. 1 is a side elevation of the tool.

Fig. 2 shows the tool lying on a surface.

Fig. 3 is a section on line 3-3 of Fig. 1.

Fig. 4 is an end elevation taken from the location shown with the numeral 4 and an arrow.

The chisel is a square section slab 1 of metal tapered down to a blunt edge. Into the end of the slab opposite the blunt end a rod or shank 2 is driven into a socket. The holder for the brush comprises a sheet metal steplike saddle 3. This step-like saddle has at the outer end a riser 4 which has its end turned over at 5 to engage the wooden brush back 6. This brush back has its upper surface 7 slightly curved or arched to cause the ends of the wire bristles 8 to stand in their assembly on a shallow arc. This makes it more effective when the brush is drawn over the chipped surface. The bottom 9 of the step-like saddle has on either side an outstanding wing it which serves to contain the brush at the sides. The bottom 9 has a longitudinally extending rib 9a positioned substantially centrally thereof. The inner end of the saddle is turned down to form a second riser or guard 11 in the step-like saddle. The outer end of the saddle is arc-welded to the thick end of the chisel and the disc-like guard is arc-welded to the shank or rod. At the same time the guard is welded to the shank, the end of a coiled Wire handle is welded to the shank. The other end of the coiled wire handle has an outstanding eye 12 which forms a hook by which the tool may be hung up on a nail or other element. It will be noticed that the seat of the saddle is set at an angle to the shank. This is a shallow angle of 15 or 20 degrees. This causes the brush to be held on angle to the main axis of the tool and we have found that this is the most effective position for the tool to do its work. The work performed by the tool is hard, rough work; consequently, the brush must be securely locked in its saddle. For this purpose I used a spring end on the clip described and claimed in my prior patent, but in order to afiord a spring action such as this required, the whole saddle had to be stamped I ited Stat Pate t out of high carbon steel which can be formed into a member whose ends and side wings will spring back into place after being distorted. High carbon steel, from which spring members are made, is much more expensive than the lower carbon or base metal steel. It was also necessary to find a tool such as a screw driver or some other tool to be forced into the clip-like end member and spring it out to free the brush. I have found that a more effective and cheaper way of providing a spring clip at the end of the saddle to hold the brush in place. I perforate the saddle at three places at the inner end. Two of these perforations take the turned-in feet 13 of the wire spring clip. This clip is formed by a piece of spring wire which is bent to form elbow 14. At the lower end of the elbow the wire is formed into two coils 15 of the same type as is found in a safety pin. This makes the arms of the clip fie'x more easily.v This clip in its normal position bears heavily down on the end of the wooden back of the brush when that has been inserted in place. The brush is held very firmly in place and will never be released in ordinary practice except when the upper end of the clip is withdrawn and this can be easily done by using a tool, preferably one of the arc-welding electrodes 17, that will always be at hand. This electrode can be inserted in the third opening 16 in the seat of the saddle. The body of the electrode 17 can be passed through the elbow loop 20 of the clip as shown in Fig. 1 and the electrode used as a lever to pry the clip backward to release the brush. The same operation can be used in opening the saddle to take the brush back. If a lighter spring is used, the thumb may be used to open the clip.

The turned-down riser or guard 11 of the saddle forms a member to arrest the hand of the welding operator so it will not slip and possibly get injured in using the tool. The guard has another useful function in holding the handle spaced from the surface on which it rests when not in use. This is helpful to the welder in picking up the handle. These welders wear heavy gloves which are very cumbersome, and it is difficult to manipulate the gloves to pick up any article, but with the spacing afforded by the guard the handle is in much better position to be picked up by the welder.

What I claim is:

l. A welders brush holder having in combination a shank, a handle secured to one end of the shank, a metal saddle provided with a bottom, said saddle being secured to the other ,end of the shank and secured to an intermediate portion of the shank near the inner endof the handle, the saddle intermediate the ends provided with turned-up wings to secured and anchor the brush at these locations and a spring wire clip secured to the bottom of the saddle at the inner end, the clip being set into the metal of the saddle and normally bearing down on the back of the brush when the brush is in place, said clip having a turned-back angular portion which may be pressed on to relieve the end of the brush so it may be freed from the saddle, and the clip being a safety pin type of member with an upper portion in the form of an elbow and a forearm which forms a loop, the central portion of the wire clip having the safety pin type coils and the remainder of the clip in the form of legs with turned-out feet which are hooked in perforations in the bottom of the saddle to anchor the clip in place.

2. The combination claimed in claim 1 with the bottom of the saddle provided at the inner end with a perforation to take a tool which may be inserted after having passed through the loop of the forearm of the wire clip to thereby .use the tool as a lever to pry open the clip to release the brush back.

3. The combination claimed in claim 1 in which the saddle is a step-like member providing with a riser at the outer end to help secure the brush in place and a second riser at the other end in the form of a disc which engages around and projects from the shank to support the handle in spaced relation when the tool is laid down on a surface.

4. A welders brush holder having in combination a shank, a handle secured to one end of the shank, a metal saddle provided 'with a bottom, said saddle being secured to the other end of the shank and secured to an intermediate portion of the shank near the inner end of the handle, the saddle intermediate the ends provided with turned-up Wings to secure and anchor the brush at these locations and a spring wire clip being set into the metal of the saddle and normally bearing down on the back of the brush when the brush is in place, said clip having a turned-back angular portion which may be pressed on to relieve the end of the brush so it may be freed from thesaddle, said saddle being a step-like member providing with a riser at the outer end to help secure the brush in place and a second riser at the other end in the form of a disc which engages around the projects from the shank to support the handle in spaced relation when the tool is laid down on a surface.

5. The combination claimed in claim 4 in which the disc guard on the inner end of the saddle is secured to an intermediate portion of the shank.

6. The combination claimed in claim 5 in which a coiled wire handle has its outer end secured to the end of the shank and its inner end secured to an intermediate portion of the shank.
