Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
125 words
A lock strip inserting tool for inserting locking strips in the groove of a structural gasket, said tool including a tool head adapted to be received in the groove of the gasket and guide a locking strip thereinto and a tool shank secured at one end to said tool head with the other end of said tool shank being adapted to be connected to a power source such as an impact hammer or the like, the improvement comprising, said tool shank including damping means for damping the vibrations imparted to the shank by the power source for transmission to the tool head whereby the vibrations received by the tool head are substantially less than the vibrations imparted to the upper end of the tool shank.
Claim 2
Dependent Claim
125 words
A lock strip inserting tool for inserting locking strips in the groove of a structural gasket, said tool including a tool head adapted to be received in the groove of the gasket and guide a locking strip thereinto and a tool shank secured at one end to said tool head with the other end of said tool shank being adapted to be connected to a power source such as an impact hammer or the like, the improvement comprising, said tool shank including damping means for damping the vibrations imparted to the shank by the power source for transmission to the tool head whereby the vibrations received by the tool head are substantially less than the vibrations imparted to the upper end of the tool shank.
Claim 3
Dependent Claim
27 words
The improvement of claim 1 wherein said shank comprises upper and lower shank portions with said damping means being interposed between said two portions of said shank.
Claim 4
Dependent Claim
20 words
The improvement of claim 2 wherein said damping means comprises a spacer clamped between adjacent ends of said two portions.
Claim 5
Dependent Claim
155 words
A lock strip inserting tool for inserting locking strips in the groove of a structural gasket, said tool including a tool head adapted to be received in the groove of the gasket and guide a locking strip thereinto and a tool shank having a lower portion secured to said tool head and an upper portion adapted to be connected to a power source such as an impact hammer or the like, the improvement comprising, said tool shank including dampiNg means interposed between said two portions of said shank and comprising a spacer clamped between adjacent ends of said two portions for damping the vibrations imparted to the shank by the power source whereby the vibrations received by the tool head are substantially less than the vibrations imparted to the upper end of the tool shank, said damping means further including a resilient sleeve telescopically received over and enclosing said adjacent ends of said shank portions.
Claim 6
Dependent Claim
155 words
A lock strip inserting tool for inserting locking strips in the groove of a structural gasket, said tool including a tool head adapted to be received in the groove of the gasket and guide a locking strip thereinto and a tool shank having a lower portion secured to said tool head and an upper portion adapted to be connected to a power source such as an impact hammer or the like, the improvement comprising, said tool shank including dampiNg means interposed between said two portions of said shank and comprising a spacer clamped between adjacent ends of said two portions for damping the vibrations imparted to the shank by the power source whereby the vibrations received by the tool head are substantially less than the vibrations imparted to the upper end of the tool shank, said damping means further including a resilient sleeve telescopically received over and enclosing said adjacent ends of said shank portions.
Claim 7
Dependent Claim
13 words
The improvement of claim 4 and further including jacket means enclosing said sleeve.
Claim 8
Dependent Claim
90 words
A tool adapted for use with an impact hammer or the like, said tool including a shank having a tool head secured at one end with the other end of said shank being adapted to be received in said hammer, the improvement comprising, said shank being divided into at least two portions, said shank portions being generally coaxially aligned, spacer means interposed between the adjacent ends of said shank portions, and a resilient sleeve received over said adjacent ends of said shank portions and frictionally and resiliently gripping said portions.
Claim 9
Dependent Claim
90 words
A tool adapted for use with an impact hammer or the like, said tool including a shank having a tool head secured at one end with the other end of said shank being adapted to be received in said hammer, the improvement comprising, said shank being divided into at least two portions, said shank portions being generally coaxially aligned, spacer means interposed between the adjacent ends of said shank portions, and a resilient sleeve received over said adjacent ends of said shank portions and frictionally and resiliently gripping said portions.
Claim 10
Dependent Claim
