Abstract
Abstract A tool is provided for tensioning a tape around an object, for connecting the ends of the tape and for cutting off the surplus, and the tool comprises a pivotal handlever engaging an element with a cutout which receives a pin on a drawing bar engaged with tape gripping and tensioning devices. An abutment limits displacement of the drawing bar so that as the handlever is alternately squeezed and released, the drawing bar is reciprocated and the tape is tensioned by the gripping and tensioning devices. When the tape tension reaches a predetermined value the pin on the drawing bar releases from the cutout under the tape tension and now the handlever is free to undergo further unlimited travel to actuate a locking device which connects the tape ends and thereafter a cutting device which severs the surplus tape beyond the connection.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
195 words
A tool for tensioning a tape wrapped around an object and for connecting the ends of the tape and cutting off the surplus when a preset tension has been reached in in the tape, said tool comprising lock means for connecting the tape ends, a displaceable hand lever having a given range of travel, means for gripping and tensioning the tape, cutting means operatively associated with the hand lever for being operated when the tape tension exceeds a predetermined value to cut the tape, coupling means between said hand lever and the gripping and tensioning means and having an engaged state to cause tensioning of the tape as the hand lever is displaced, and having a disengaged state at a predetermined tension in the tape, and stop means to limit displacement of the hand lever to a restricted portion of the range of travel of the hand lever with the coupling mans in an engaged state said hand lever being operatively positioned to activate the loCk means and thereafter the cutting means only when the hand lever is beyond the restricted portion of the range of travel after the coupling means is in disengaged state.
Claim 2
Dependent Claim
195 words
A tool for tensioning a tape wrapped around an object and for connecting the ends of the tape and cutting off the surplus when a preset tension has been reached in in the tape, said tool comprising lock means for connecting the tape ends, a displaceable hand lever having a given range of travel, means for gripping and tensioning the tape, cutting means operatively associated with the hand lever for being operated when the tape tension exceeds a predetermined value to cut the tape, coupling means between said hand lever and the gripping and tensioning means and having an engaged state to cause tensioning of the tape as the hand lever is displaced, and having a disengaged state at a predetermined tension in the tape, and stop means to limit displacement of the hand lever to a restricted portion of the range of travel of the hand lever with the coupling mans in an engaged state said hand lever being operatively positioned to activate the loCk means and thereafter the cutting means only when the hand lever is beyond the restricted portion of the range of travel after the coupling means is in disengaged state.
Claim 3
Dependent Claim
42 words
A tool as claimed in claim 1 comprising means for releasing the gripping and tensioning means after the ends of the tape have been connected and before operation of the cutting means whereby the tape ends are cut when not under tension.
Claim 4
Dependent Claim
47 words
A tool as claimed in claim 1, wherein said coupling means comprises an element with an inclined surface, a glide member engaging the inclined surface, and means applying the glide member against the inclined surface to prevent disengagement therefrom up to the predetermined tension in the tape.
Claim 5
Dependent Claim
21 words
A tool as claimed in claim 3, wherein said means applying the glide member against the inclined surface comprises spring means.
Claim 6
Dependent Claim
32 words
A tool as claimed in claim 3, wherein said inclined surface is constituted by an edge cutout in said element with an inclined flank, said glide member being received in said cutout.
Claim 7
Dependent Claim
43 words
A tool as claimed in claim 5, wherein said element is supported for movement and has an edge surface adjoining the cutout for receiving the glide member after the latter is removed from the cutout in the disengaged state of the coupling means.
Claim 8
Dependent Claim
57 words
A tool as claimed in claim 6, wherein said coupling means comprises a displaceable drawing bar on which said glider is secured, said gripping and tensioning means being actuated by said drawing bar, said stop means comprising a fixed abutment positioned to engage the drawing bar and limit movement thereof when the glider is in said cutout.
Claim 9
Dependent Claim
48 words
A tool as claimed in claim 7, wherein said abutment includes a flange overlying said glider when the latter in said cutout and the drawing bar is in engagement with said abutment to prevent removal of the glider from said cutout below the predetermined tension in the tape.
Claim 10
Dependent Claim
51 words
A tool as claimed in claim 7, wherein said hand lever includes means engaging said element with the cutout such that with the glider in the cutout the hand lever is limited to the restricted portion of the range of its travel by contact of the drawing bar with said abutment.
Claim 11
Dependent Claim
47 words
A tool as claimed in claim 9 comprising further spring means acting on said element with the cutout to resist movement thereof and urge the same and said hand lever therewith to an initial position from which movement of the hand lever produces tension in the tape.
