Abstract

Abstract A tool having a dual purpose ram formed with a first portion to drive a knife through a cable to sever it, and a second portion to crimp a connector onto the end of the cable. The knife is made sufficiently deep in width that it will sever the cable completely even though contact between the ram and the cable by the second portion limits downward movement of the ram at the end of the severing stroke.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 148 words
A severing and crimping tool for cables comprising a frame having a vertical guideway, a ram non-rotatably, slidably fitting in said guideway, a knife constituting an element separate from said ram, a stationary member having a recess located below and in alignment with said ram and adapted to hold the cable to be cut and thereafter a connector to be crimped, means mounting said knife on said frame independently of said ram and in spaced relation from said ram for movement of said knife from an upper position to a lower position along a predetermined path coinciding with a portion of said ram, means on said ram whereby said ram may be actuated to engage said knife for cutting the cable and for subsequently crimping a connector onto the cable, said ram being configured on its working end for direct indentation into a connector surrounding a cable portion.
Claim 2
Dependent Claim 148 words
A severing and crimping tool for cables comprising a frame having a vertical guideway, a ram non-rotatably, slidably fitting in said guideway, a knife constituting an element separate from said ram, a stationary member having a recess located below and in alignment with said ram and adapted to hold the cable to be cut and thereafter a connector to be crimped, means mounting said knife on said frame independently of said ram and in spaced relation from said ram for movement of said knife from an upper position to a lower position along a predetermined path coinciding with a portion of said ram, means on said ram whereby said ram may be actuated to engage said knife for cutting the cable and for subsequently crimping a connector onto the cable, said ram being configured on its working end for direct indentation into a connector surrounding a cable portion.
Claim 3
Dependent Claim 39 words
A tool as recited in claim 1 in which said knife is mounted at one end on a fixed stationary portion of said frame for pivotal movement about a stationary axis perpendicular to a plane containing said predetermined path.
Claim 4
Dependent Claim 65 words
A tool as recited in claim 2 in which said knife extends generally horizontally from its pivotal axis toward said stationary member and has a curved cutting edge at the end portion thereof remote from its pivotal axis, said knife having a blunt edge for abutting engagement with said ram, said blunt edge, in the lower position of said knife, being disposed below said recess.
Claim 5
Dependent Claim 44 words
A tool as recited in claim 3 in which said ram has a notched operating end providing a shoulder for engaging said blunt edge of said knife to drive the same, and has a crimping portion aligned with said stationary member for crimping purposes.
Claim 6
Dependent Claim 49 words
A tool as recited in claim 4 wherein the dimension of said knife between its cutting edge and its blunt edge is sufficiently great as to facilitate complete severing of a cable despite movement-limiting engagement between said crimping portion and said cable at the end of said severing step.
Claim 7
Dependent Claim 89 words
A severing and crimping tool for cables comprising a frame, a knife mounted on the frame for movement in a predetermined direction, a stationary member to hold the cable to be cut, a ram for actuating the knife and for crimping a connector onto the cable, and a guide for an end portion of said knife to hold it in a predetermined cutting plane during the severing step, said ram being configured on its working end for direct indentation into the portion of the cable surrounded by the connector.
Claim 8
Dependent Claim 89 words
A severing and crimping tool for cables comprising a frame, a knife mounted on the frame for movement in a predetermined direction, a stationary member to hold the cable to be cut, a ram for actuating the knife and for crimping a connector onto the cable, and a guide for an end portion of said knife to hold it in a predetermined cutting plane during the severing step, said ram being configured on its working end for direct indentation into the portion of the cable surrounded by the connector.
Claim 9
Dependent Claim 19 words
A tool as recited in claim 6, in which said guide is an integral part of said stationary member.
Claim 10
Dependent Claim 27 words
A tool as recited in claim 7 in which said stationary member comprises a block having a V-shaped supporting surface for a cable or connector equipped cable.
Claim 11
Dependent Claim 48 words
A tool as recited in claim 8 in which the cutting edge of said knife is concavely arcuate and the parts are so dimensioned that the most indented point of said cutting edge substantially coincides with the most indented point on said V-shaped surface during the severing step.
