Abstract

A cutting arm includes a base having a post receiving passageway extending through the base, a cutting assembly attached to the base, and a sliding plate attached to the base and movable with respect to the base between an engaging position and a releasing position. The sliding plate engages a post disposed in the post receiving passageway in the engaging position and releasably secures the cutting arm to the post.

First claim

What is claimed is:

1. A cutting arm, comprising:
a base having a post receiving passageway extending through the base and a biasing member recess extending into a front side of the base;
a cutting assembly attached to the base; and
a sliding plate attached to the front side of the base and movable linearly along the front side with respect to the base between an engaging position and a releasing position, the sliding plate covers the biasing member recess, the sliding plate engages a post disposed in the post receiving passageway in the engaging position and releasably secures the cutting arm to the post, the cutting arm is pivotable about the post while the sliding plate engages the post in the engaging position, the sliding plate has an engaging end with a protrusion, and the protrusion engages a groove of the post when the sliding plate is in the engaging position.

2. The cutting arm of claim 1 , further comprising a biasing member applying a biasing force biasing the sliding plate toward the engaging position.

3. The cutting arm of claim 2 , wherein the biasing member is disposed in the biasing member recess of the base.

4. The cutting arm of claim 3 , wherein the sliding plate has a bearing member extending into the biasing member recess.

5. The cutting arm of claim 4 , wherein a first end of the biasing member abuts the base and a second end of the biasing member abuts the bearing member.

6. The cutting arm of claim 5 , wherein the biasing member is compressed between the base and the bearing member in the releasing position.

7. The cutting arm of claim 1 , wherein the protrusion is disengaged and spaced apart from the groove when the sliding plate is in the releasing position.

8. The cutting arm of claim 1 , wherein the sliding plate has a plurality of sliding slots and a plurality of plate retainers attaching the sliding plate to the base, each of the plate retainers extends through one of the sliding slots.

9. The cutting arm of claim 8 , wherein the plate retainers are disposed at an upper end of each of the sliding slots when the sliding plate is in the engaging position and the plate retainers are disposed at a lower end of each of the sliding slots when the sliding plate is in the releasing position.

10. The cutting arm of claim 1 , wherein the cutting assembly includes a cutting wheel attached to the base by a wheel retaining portion, and the cutting wheel is rotatable with respect to the base and the wheel retaining portion.

11. The cutting arm of claim 10 , wherein the cutting assembly includes a cutting blade having a first end attached to the base and a second end extending from the base, and the second end has a contour edge.

12. The cutting arm of claim 11 , wherein the cutting wheel extends beyond a bottom end and a first lateral side of the base, and the cutting blade extends beyond the bottom end and a second lateral side of the base opposite the first lateral side.

13. The cutting arm of claim 1 , wherein the base has a follower slot extending into a rear side of the base opposite the front side of the base, and the cutting assembly is attached to the front side.

14. A cable preparation machine, comprising:
a first wheel having a post fixed to and extending from the first wheel;
a cutting arm including a base having a post receiving passageway extending through the base and a biasing member recess extending into a front side of the base, a cutting assembly attached to the base, and a sliding plate attached to the front side of the base and movable along the front side with respect to the base between an engaging position and a releasing position, the sliding plate covers the biasing member recess, the post is disposed in the post receiving passageway and the sliding plate engages the post in the engaging position, releasably securing the cutting arm to the post; and
a second wheel having a cam fixed to and extending from the second wheel, the cam extends through a cam slot in the first wheel and into a follower slot of the base, the cutting arm is pivotable about the post by movement of the first wheel with respect to the second wheel while the sliding plate engages the post in the engaging position.

15. The cable preparation machine of claim 14 , wherein the post is inserted into the post receiving passageway and removed from the post receiving passageway with the sliding plate in the releasing position.

16. The cable preparation machine of claim 14 , further comprising a cable bore, the first wheel and the second wheel are rotatable with respect to each other about the cable bore.
