A. DOS SANTOS ET AL June 30, 1953 BUNG WRENCH Filed Aug. 7. 1950 Alfred Dos Santos William K. Mossman INVENTORS Patented June 30, 1953 UNITED BUNG WRENCH Alfred Dos Santos and William K. Mossman, Honolulu, Territory of Hawaii Application August 7, 1950, Serial No. 178,034

1 Claim.

The present invention relates to improvements in bung wrenches for use in connection with the removal of bungs from barrels and the like.

An object of the present invention is to provide a bung wrench which is provided with a plurality of tool engaging elements whereby bung plugs of various forms may be removed or inserted into barrels and the like.

A further object of the present invention is to provide a hung wrench wherein a plurality of flat plates of differing widths are provided for engagement with the slots of bungs of varying diameters.

Still another object of the present invention is to provide a bung wrench wherein the tool engaging member is adapted to engage the noncircular nut for rotating the same and wherein the non-circular hollow open ended member is provided with a core element having a slotted end for engagement with the center portions of one form of bung plug.

Various other objects and advantages will become apparent from the detailed description to follow. The best form in which I have contemplated applying my invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a bottom view of the present invention;

Figure 2 is a vertical longitudinal sectional view taken substantially along the plane of line 2-2 of Figure 1;

Figure 3 shows an elevation of the left hand portion of the bung wrench shown in Figure 1, after the wrench therein has been inverted;

Figure 4 is a vertical transverse sectional view taken substantially along the plane of line 4-4 of Figure 2; and

Figure 5 is a detail view similar to Figure 3 but showing the opposite side thereof.

Referring more particularly to the drawings, wherein like numerals designate like parts throughout, the numeral [0 designates generally the bung wrench of the present invention. The numeral l2 designates generally a handle means and the numeral [4 designates generally a tool means associated with the handle means l2.

The handle means I 2 is formed from a flat elongated plate 26 having an angulated end l6 forming a work engaging portion and is provided at its other end with a reduced elongated portion IS. A hollow tubular element 20 encompasses the elongated reduced portion I8, is welded thereto, and provides a handle portion.

The tool means I4 includes a hollow open ended non-circular socket member 22 which is welded to a bottom face 24 of the flat strap 26 of the handle means l2. The hollow open ended member 22 is shown here as hexagonal but may be of any desired form conventionally used for bung plugs and the like. Axially disposed within the hollow open ended member 22 is a shank or core element 28 which has an end portion fixed in any suitable manner in an opening 30 in the flat bar 26. The core element 28 is of circular form and is provided with a transverse recess or kerf 32 at its lower end for engagement with a projection within a recess on a bung plug. It should be noted that the core element 28 extends beyond a bottom edge 34 of the hollow open ended member 22 whereby a tool end 36 of the core element may be employed separately if desired.

A pair of laterally extending fiat plates 38 and 40 are secured to the opposite sides of the hollow open ended member 22 and provide a pair of tool engaging members which may be employed for removing bungs of different forms. As best seen in Figures 3 through 5, the flat plates 40 and 38 are of different cross section, the flat plate 40 being of elongated rectangular cross section while the plate 38 is of substantially square form.

From the foregoing, it will be seen that a bung wrench has been provided which is readily adapted for use with bung plugs of varying form, and wherein the bung plugs are provided with either slots, non-circular peripheries, notches or projections.

It will also be seen that a bung wrench has been provided which is economical of manufacture and relatively simple.

Having described the invention, what is claimed as new is:

A wrench for polygonal, substantially cupshaped bungs having a diametrically extending rib, comprising a fiat metallic bar having an opening in one end portion, a shank fixed in the opening, and a polygonal socket member for the reception of a hung, fixed on the bar in spaced, concentric relation to the shank, the free end portion of said shank projecting beyond the socket member and having a kerf therein for the reception of the rib when said socket member is engaged with the bung.
