Abstract
A saw consisting of a loop of cable on which are mounted a polarity of abrasive elements, each element having a small sleeve.
Claims4
A method of forming a cable type saw, comprising the steps of:
- a. forming a main body element of malleable metal having two axially adjacent cylindrical portions, one portion having a large diameter and the other portion having a small diameter,
- b. placing the body element in a bore in a die, which bore has the same diameter as the said large diameter,
- c. placing a powdered abrasive substance in the space between the surface of the bore and the portion of small diameter,
- d. pressing the substance in the space axially toward the portion of large diameter, thereby causing a part of the small diameter portion to extend axially beyond the substance,
- e. raising the temperature of the pressed substance to produce a solid body,
- f. forming a centrally-located axially-directed bore in the body,
- g. placing a piece of flexible cable through the bore in the body,
- h. placing a collar concentrically over the said part of the small diameter portion, and
- i. swaging the collar so that it fixedly engages the body and so that the body fixedly engages the cable.

- i. swaging the collar so that it fixedly engages the body and the body beneath it fixedly engages the cable,
- j. forming a second portion of small diameter from a part of the portion of large diameter, and
- k. swaging the second portion so that the body beneath it fixedly engages the cable.
