CABLE-G RIP.

SPECIFICATION forming part of Letters Patent No. 394,796, dated December 18, 1888.

Application led February 6, 1888. Serial No. 263,089. (No model.)

To all whom it may concern.'

Be it known that I, DUANE A. TINKLE- PAUGH, of Kansas City, in the county of Jackson and State 0f Missouri, have vinvented a certain new and useful Improvement in Ca ble-Grips, of which the following-is a full, clear, and exact description, reference being' had to the accompanying drawings, forming part of this speciiication, and in which- Figure I is a perspective view illustrating' my invention. Fig. II is a top view of a castiron die, showing the groove into which the copper facing is east. Fig. III is a section taken on line III III, Fig. II, showing the facing in place.

My invention relates to an improvement in dies for cable-grips; and my invention consists in features of novelty, hereinafter fully described, and pointed out in the claims.

Referring to the drawings, l represents a metal die, made of cast-iron or other suitable material, one of which is designed to be set in the inner face of each of the gripq'aws (not shown) by anysuitable and well-known means. On the top of the die is formed a groove, 2, preferably semicircular in shape. In the bottom of the groove 2 are a series of holes, 3.

4 represents a copper facing' or bushing, which is cast into the groove 2, a portion of it entering the holes 3, which forms studs 5, the object of the studs being to prevent the facing from moving endwise and to hold it in a rigid position.

The body of the die, preferably, has side walls, (5, outside of the groove to form a rm backing to the copper lining, (which is of course a soft metah) thus keeping it from being spread by the cable end walls, '7, which prevent its longitudinal movement.

The use of the copper lining for cable-grip dies will add very materially to the life of a cable, as it presents a soft-metal bearing or surface to the hard metal of the cable.

I am of course aware that grip-dies have heretofore been lined with Babbitt and other kinds of hard metal, and make no claim as inventor to such.

I claim as my inventionl. In a cable-grip, the combination of a removable grooved iron die and a copper facing cast in the groove, substantially as described, and for the purpose set forth.

2. In a cable-grip, the combination of the die l, provided with a groove, 2, and holes 3, and a copper facing, 4, cast in said groove and holes, substantially as and for the purpose set forth.

3. In a cable-grip, in combination with the iron die having a groove, 2, and side walls, 6, a copper facing or bushing fitting in said groove and kept from expansion by said side walls, substantially as and for the purpose set forth.
