April 30, T S-[O WELDER'S (SHIPPING AND CLEANING TOOL Filed Aug. 1, 1966 INVEN OR FREDERLCK 1'. MARSTON United States Patent 3 380,096 WELDERS CHIPPING AND CLEANING TOOL Frederick T. Marston, 223 Therrien St., Maillardville, New Westminster, British Columbia, Canada Filed Aug. 1, 1966, Ser. No. 569,508 1 Claim. (Cl. --105) ABSTRACT OF THE DISCLOSURE Welders chipping and cleaning tool having a chipping attachment detachably connectable to a brush handle, the chipping attachment being provided with a socket into which the brush handle fittedly extends.

This invention relates to a tool used by welders for chipping and cleaning a surface after or before a welding operation.

In the manufacture of tools of the above nature, it has generally been the practice to provide a chipping tool having an elongated handle to which a wire brush is detachably secured. Although the tool constructed in this manner is efficient, its service life has been relatively short by reason of the fact that during its chipping operation, the connection between the brush and the handle of the chipper invariably loosens, resulting in excessive wear of the connecting elements.

The present invention provides a tool of this nature wherein the chipping tool is detachably secured to the handle of a brush which has resulted in a tool having a long service life.

Furthermore, this invention provides a tool wherein the point elements of the chipper may be easily and quickly removed from the entire assembly and replaced with a new point element so as to maintain the welders efiiciency at a high level.

The present invention comprises a head portion having a socket formed therein for fittedly receiving one end of a handle of a welders brush, an elongated connecting piece connected to the head at one end and extending along one side of said handle, means for detachably securing the connecting piece at its other end to the handle so as to maintain the handle in engagement with the head section, and a point section secured to the head section directed in a direction substantially opposite to that of the brush.

In the drawings which illustrate the invention,

FIGURE 1 is a side view of the invention,

FIGURE 2 is an end view of the invention in the direction 22 of FIGURE 1,

FIGURE 3 is an isometric view of the chipper shown in a condition detached from the handle of the welding brush.

Referring to the drawings, the numeral 10 designates a welders brush having an elongated handle 11 normally formed of wood and having a square or rectangular cross section. This handle may be either straight or gently curved and, adjacent one end 12 thereof, wire bristles 13 extend from one side surface 14 of the handle.

The numeral 18 designates a chipping attachment formed having a head portion 19, a laterally projecting connecting piece 20, and a point element 21 detachably secured to said head portion. This head portion and connecting piece are preferably formed of cast steel as one integral unit. The head portion is relatively massive having a shaft or shank portion 23 of cylindrical configuration, one end 25 of which is drawn flat and provided with a centrally located internally threaded co-axially extending socket 26. The head portion 19 at the other end 28 of the shaft portion 23 is of cubical shape having a laterally extending rectangularly shaped socket 30 formed therein, said socket being shaped so as to fittedly receive the end 12 of the handle 11.

iCe

The connecting piece 20 is formed as an elongated relatively thick strap extending laterally from said head portion substantially intermediately between the

sockets

23 and 30, said connecting piece having a hole 32 formed at its free end 35. This connecting piece is arcuately shaped in a longitudinal direction.

The point element 21 is preferably composed of a tough well resisted material, such as magnesium steel, and is of elongated shape having one end 38 formed as a point or preferred as a chisel, and is shaped at its other end 40 to the same configuration and dimension as the end 28 of the shaft section 23. From this end 40 of the point element 21 projects a centrally located threaded boss 42 for engaging the threaded socket 26, a lock washer 43 being provided between the head portion 19 and point element 21 so as to prevent inadvertent loosening of the latter under constant use.

The chipping attachment 18 is of course attached to the welders brush 10 by fitting the end 12 of the latter into the socket 30, then passing the bolt 44 through the opening hole 32 in the connecting piece 20 and thence through a suitably positioned hole 45 provided in the handle 11 for that purpose.

It will be seen that with the foregoing construction, the chipping attachment 18 may be easily and quickly secured to most conventional welders brushes, the connection achieved being firm and substantial. Furthermore, in view of the positive connection between the handle 11 of the brush and the head portion 19 of the chipping attachment which permits the relative movement, there will be no tendency for the connection to loosen when the tool is used for chipping purposes.

It is also to be noted that the point element 21 may be easily and quickly replaced when it becomes worn or when it is necessary to change the point element having regard to the nature of the work to be formed, flats 46 being formed at the base of the point element to permit a crescent or like wrench to be employed for this purpose.

What I claim as my invention is:

1. A welders tool comprising in combination a welders brush having an elongated handle and having brush bristles extending in one direction from an edge thereof adjacent one end thereof and a chipping attachment comprising, a head section having a first socket formed therein for fittedly receiving said one end of the handle and having a threaded socket formed therein extending in a substantially opposite direction to the bristles of the brush, an elongated connecting piece connected to the head section at one end and extending along one side of said handle, means for detachably securing the connecting piece at its other end to the handle so as to maintain the handle in engagement with the head section, and an elongated point section having a point at one end and threaded at its other end for threaded engagement with said threaded socket.
