FOSTER H. LEIDECKER, 0F MARIETTA, OHIO, ASSIGNOE, BY MESNE ASSIGNMENTS, TO THE LEIDECKER TOOL COMPANY. OF IMABIETTA, OHIO, A CORPORATION OF OHIO.

WIRE-ROPE KNIFE.

Application filed August'22, 1921.

To all "whom it may concern.

Be it known that I, Fos'rnn H. LEIDECKER, residing at Marietta, county of Washington, and State of Ohio, a citizen of the United States, have invented certain new and useful Improvements in lVire-Rope Knives, of which the following is a specification.

This invention relates to an improvement in wire rope knives, and the present invention is an improvement on the patent to Beasley, No. 923,482, granted June 1, 1909.

The invention consists mainly in two members having beveled sliding or shearing connection with each other, with interchangeable cutting-blades, and a spring for returning the parts to normal.

In the accompanying drawings:

Figure 1 is a bottom plan view;

Fig. 2 is a side view;

Fig. 3 is a top plan;

Figs. 4 and 5 are enlarged side views; and

Figs. 6, 7, 8 and 9 are details.

A- represents the shank of the tool, through which the cable to be out passes lengthwise; the lower edge 1 is beveled; and 2 is the movable cutting member hav'mg a beveled edge 3 adapted to engage and ride upon the edge 1 in the cutting or shearing operation.

Dove tailed cutting-blades 4t and 5 are interchangeably slid into correspondinglyshaped transverse grooves 6 and 7 respectively in the two beveled faces/1 and 3, as shown in Figs 4;, 5, 6 and 7. These interchangeable blades are held removably in place by screws 8.

The two main parts A. and 2 of the tool are held together by links 9, pivoted at 10, and having elongated slots 11 which receive .the bolt 12, and a spring 13 bears down Serial No. 494,187.

groove 14: extending longitudinally of the tool, and as the tool is suddenly lowered the impact upon the part 2 causes the beveled ends 1 and 3 of the parts A and 2 to slide, and the cable caught in the U-shaped recesses 15 of the blade is severed or cut as between the members of a pair of ordinary shears.

In this way, the wearing parts are made of ordinary tool steel, and are not only interchangeable but are renewable at any time with slight difliculty and trifling expense; and at the same time the proper op eration of the tool is insured by the action of the spring 13, which returns the parts to normal and in readiness for a repetition of the operation the moment the tool has done its work.

What is claimed is l. A rope knife including two members engaging each other upon a bevel loosely linked together, and through which the rope to be cut is adapted to extend. and a strip of spring plate rigidly secured to the edge of one member and lying flat thereagainst with its free end projecting against the corresponding side of the other member.

2. A rope knife including two members engaging each other upon a bevel loosely linked together. and through which the rope to be cut is adapted to extend, and a strip of spring plate rigidly secured to the edge of one member and lying flat thereagainst with its free end projecting against the corresponding side of the other member, the free end of said. spring enlarged on the side toward the member which it engages. whereby normally to tend to press the edge thereof! out of alignment with the corresponding edge of the other member.

In testimony whereof I hereunto affix my signature.
