Abstract
A tool for holding a torch tip and a blank cartridge respective to one another so that the blank cartridge can be detonated and the high-velocity gases issuing therefrom used to clean out the flow passageways of the torch tip.
Claims4
In a hand-held torch tip cleaning apparatus for effecting a high pressure differential across the flow passageway of a torch tip removably contained within the apparatus and from which debris causing obstruction thereof is to be ejected, the combination comprising:
- a central body member having a central bore formed therethrough with a marginal length of said central bore being sized to removably receive a blank cartridge concentrically arranged in axially aligned relationship therein and seated at one marginal end therein;
- a breech member removably affixed to the cartridge containing end of said central body member, said breech member having an axial bore which is axially aligned with said central bore, a spring loaded firing pin assembly slidably received in axial alignment with respect to said axial bore and with the detonator of the cartridge, such that the firing pin assembly is yieldably biased away from the cartridge;
- said firing pin assembly having an elongated shaft axially aligned with said central and axial bore and extending away from and clear of said breech member a distance at least equal to the longitudinal axial length of the central bore formed through said central member;
- so that the breech member can be removed from the central member and said shaft can then be used to forcibly remove a spent cartridge from seated relationship within said central member;
- a torch tip holding member having an axial bore formed therethrough with a free depending end portion thereof being made into the form of a muzzle, the opposed end portion of said holding member being removably affixed in axially aligned relationship to said central body member, a marginal length of the last said axial bore being sized to removably receive a torch tip therein such that the flow passageways of the torch tip are axially aligned with said axial bore;
- the outer periphery of the torch tip being sealingly engaged with the inner periphery of the last said axial bore so that when a torch tip is placed into the torch tip holder and a blank cartridge is placed into the central body member, the firing pin assembly can be struck, thereby causing the primer engaging end thereof to move into contact with and detonate the explosive charge thereof, thereby causing the explosive gases to develop a high pressure differential across the torch tip, and the explosive gases to flow through the passageways of
A hand-held tool for holding a blank cartridge and a plugged torch tip so that the blank cartridge can be detonated and the explosive gases of the resulting reaction directed through a plugged passageway of the torch tip to thereby unplug the passageway, said tool comprising first, second, and third members having means by which they are connected to one another in series relationship to thereby provide an elongated body which is separable into its recited first, second, and third components;
- means forming a firing pin assembly, said firing pin assembly having an elongated shaft thereon;
- a longitudinally extending axial bore formed through said elongated body;
- said first member forming one end of said bore, said third member forming an opposed end of said bore, said third member being closed by said firing pin assembly being slidably received in a reciprocating manner within a marginal, reduced end of said bore;
- an outlet formed in said first member in opposed relationship to said firing pin assembly, through which gases may be expelled to the atmosphere;
- said bore in said first and second members being sized to receive a torch tip securely seated therein so that any explosive gases flowing through said axial passageway are forced to travel through any passageway found in said torch tip;
- said bore in said second member being sized to receive a blank cartridge seated in axially aligned relationship therein, with the detonator thereof being aligned such as to be detonated by said firing pin assembly;
- said first, second, third members, said cartridge, said firing pin assembly, and said torch tip being concentrically arranged with respect to one another;
- said elongated shaft having a marginal portion which extends away from said third member a distance equal to the length of the axial bore formed through said second member, so that said third member can be removed from said second member and said shaft can then be used to forcibly remove a spent cartridge from seated relationship respective to said second member.
