Abstract

Abstract A plural bung tool for removing or replacing barrel bungs, comprising one unitary head having a socket or other standard fitting thereon for mounting on the shaft of a standard tool, including a compressed air driven tool or a manual wrench, and having a plurality of cavities and faces arranged to fit six or more existing bungs. The head includes a sleeve-like body near one end of which is mounted a hexagonal cavity collar for fitting the hexagonal bungs and within said hexagonal collar extending and protruding therefrom a second sleeve defining opposed jaws recessed to fit a smaller square or rectangular recessed bung fitting. The main body includes a passageway which is rectangular or square but not circular so that a spring biased bifurcated jaw travels therein to be pushed out of the way when fitting the plural tool second jaw collar to a bung. The bifurcated, sliding jaw arrangement is insertable inside the type of small bung fitting which has a cavity with opposed protrusions thereon and said second bifurcated jaw will also insert between projecting, parallel plates in another type of bung fitting. The second opposed jaw arrangement will fit over certain hexagonal bungs and some square or rectangular bungs. Thus, the single tool head fits any one of six or more existing bungs simply by inserting same thereon or thereinto as the case may be without further manipulative work.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 136 words
In a single bung tool implement for removing one of several shapes and configurations of bungs: a. an elongated tool body receiving a tool driving means such as a standard wrench or power tool shaft therein and having an internal chamber therein, b. a multi-sided tool implement on the outside of said body having a large cavity which fits over a large multi-sided bung, c. a pair of spaced, projecting jaws inside said multi-sided implement and projecting outwardly therefrom and being attached to said tool body, d. said jaws having flat sides on the inside thereof corresponding to the edges of a bung and having a space between said jaws in which portions of another bung will fit, and e. a movable implement mounted in said chamber and having spaced projections thereon with a space therebetween.
Claim 2
Dependent Claim 136 words
In a single bung tool implement for removing one of several shapes and configurations of bungs: a. an elongated tool body receiving a tool driving means such as a standard wrench or power tool shaft therein and having an internal chamber therein, b. a multi-sided tool implement on the outside of said body having a large cavity which fits over a large multi-sided bung, c. a pair of spaced, projecting jaws inside said multi-sided implement and projecting outwardly therefrom and being attached to said tool body, d. said jaws having flat sides on the inside thereof corresponding to the edges of a bung and having a space between said jaws in which portions of another bung will fit, and e. a movable implement mounted in said chamber and having spaced projections thereon with a space therebetween.
Claim 3
Dependent Claim 50 words
The bung tool in claim 1: said implement being spring biased and said projections fitting into the cavity of a bung having portions thereof projecting into the space between said projections, whereby said tool may be fitted to any one of several different bungs for removal or replacement of same.
Claim 4
Dependent Claim 27 words
The bung tool in claim 2: wherein said movable implement is retained against rotation whereby said implement moves in a line but does not rotate or turn.
Claim 5
Dependent Claim 18 words
The tool in claim 3: said implement having a stop means thereon to prevent dislodgement from said chamber.
Claim 6
Dependent Claim 20 words
The tool in claim 1: said flat sides on said projecting jaws being angularly positioned to present a multi-sided configuration.
Claim 7
Dependent Claim 45 words
The tool in claim 5: said projecting jaws having a space therebetween and said space having flat edges on opposite sides thereof and closer together than said flat sides whereby said jaws present a tool across said opening of less size than the multi-sided configuration.
Claim 8
Dependent Claim 67 words
The tool in claim 1: said projections on said implement having spaces therebetween and the inside edges of said projections being flat and the outside of said projections being flat whereby said projections may be fitted inside a bung opening to have portions thereof in said space or said projections may be fitted with the outside edges engaging a bung with two flat plates having space therebetween.
Claim 9
Dependent Claim 157 words
The bung tool in claim 1: wherein said movable implement is retained against rotation whereby said implement moves in a line but does not rotate or turn, said implement having a stop means thereon to prevent dislodgement from said chamber, said flat sides on said projecting jaws being angularly positioned to present a multi-sided configuration, said projecting jaws having a space therebetween and said space having flat edges on opposite sides thereof and closer together than said flat sides whereby said jaws present a tool across said opening of less size than the multi-sided configuration, said projections on said implement having spaces therebetween and the inside edges of said projections being flat and the outside of said projections being flat whereby said projections may be fitted inside a bung opening to have portions thereof iN said space or said projections may be fitted with the outside edges engaging a bung with two flat plates having space therebetween.
Claim 10
Dependent Claim 50 words
The bung tool in claim 7: said implement being spring biased and said projections fitting into the cavity of a bung having portions thereof projecting into the space between said projections, whereby said tool may be fitted to any one of several different bungs for removal or replacement of same.
Claim 11
Dependent Claim 27 words
The bung tool in claim 9: wherein said movable implement is retained against rotation whereby said implement moves in a line but does not rotate or turn.
