EDWARD P. FREDERICK AND HENRY NIEMEIER, OF ST. LOUIS, MISSOURI, ASSIGNORS TO JOSEPH D. BASCOM, OF ST. LOUIS, MISSOURI.

WIRE-ROPE CLAMP.

To all whom it may concern:

Be it known that we, EDWARD P. FRED- ERICK and HENRY 'NIEMEIER, citizens of the United States, residing in the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in ire-Rope Clamps, of which the following is a specification.

This invention relates to attachments for ropes, cables, and the like, and has for its object to provide an improved clamp, which is adapted to hold the end of a rope, cable, or the like, and is designed so that a draft hook or any other device can be attached thereto. the same being particularly well adapted for use in connection with the towline, which is disclosed in United States Letters Patent, No. 1,009,633, granted to Joseph D. Bascom, November 21, 1911.

Further, the present invention consists of the novel features of construction and arrangement of parts hereinafter more fully described and pointed out in the claims.

In the accompanying drawings forming part of this specification, in which like numbers of reference denote like parts wherever they occur, Figure 1 is a perspective view of a clamp embodying the present invention, showing same holding an end of a rope and having a draft-hook attached thereto; Fig. 2 is a side elevation of the clamp with the draft-hook detached therefrom; Fig. 3 is an interior plan view of one of the parts of the clamp; Fig. 4; is an interior perspective view of the other part of the clamp: Fig. 5 is a sectional view on the line 55, Fig. 1; Figs. 6 to 9, inclusive, are detailed views of an alternate form of the invention; and Fig. 10 is a sectional view on the line 10-10, Fig. 6.

The clamp consists of two members 1 and 2, which members are preferably formed with somewhat of an elliptical configuration and are fastened together by means of a bolt 3 or the like, said bolt extending through openings 4 in approximately the centers of said members. The member 1 is relatively longer than the member 2 and bears a lug 5, which projects from the inner face of said member 1 at one end thereof, the end face of the lug 5 being flush with the end face of the member 1, and the inner face 6 of said lug being preferably arranged to slope so as to hold the beveled end 7 of the member 2 in place, thereby preventing the Specification of Letters Patent.

end of the member 2 from projecting above the outer surface of said lug. A lug or pro- ]ection 2 on the beveled end 7 of the member 2 seats in a notch 1 in the lug 5 and thereby prevents lateral movement of one member with respect to the other. An opening 8 is preferably formed partly in the end of the member 1 that bears the lug 3 and partly in said lug, so that its axis substantially coincides with the longitudinal axis of the clamp, and is of such size that the end of a rope or cable 9 to be clamped can pass therethrough, said" rope or cable being preferably formed of wire.

Grooves

10 and 11 in the inner faces of the members 1 and 2, respectively, register with each other and unite to form somewhat of an elliptical-shaped space, which communicates with the opening 8 for the purpose now to be described.

The rope or cable 9 is passed through the opening 8 in the member 1 and is then formed in a loop 12 to fit in the groove 10 in said member, after which the end of the rope or cable is secured to the main part thereof b wire seizing 13 or other suitable means. The member 2 is then placed with its inner face covering the inner face of the member 1 so that the part of the loop 12 that proiects from the groove 10 in member 1 will seat in the groove 11 in the mem her 2-. and the beveled end 7 of the member 2 underlies the sloping face 6 of the lug 5 on member 1, whereupon the bolt 3 is passed through the openings 4: in the members 1 and 2 and the nut thereon tightened. thereby holding said members securely together. and. also. causing said members to clamp and hold the loop 12 firmly in the

grooves

10 and 11. It will be observed that the bolt 3 extends through approximately the center of the loop 12, an obiect of this arrangement being to cause the members 1 and 2 to exert substantially a uniform pressure upon the whole loop 12, so as to hold the latter securely in the

grooves

10 and 11.

The ends of the members 1 and 2 that extend beyond the loop 12 have openings 14: extending transversely therethrough, which openings register with each other so as to receive a bolt or pin 15 for the purpose of attaching a clevis 16 or the like to the ends of said members. Said clevis may pass through the eye 17 of a draft-hook 18 or may have anything else attached thereto.

It will be observed that the axis of the opening 8 passes through the axes of the

bolts

3 and 15, so that said bolts will be directly in line with the pull on the rope or cable 9, the advantage of this arrangement being obvious.

In the alternate form of the invention depicted in Figs. 6 to 10, inclusive, the mem her 2 is relatively shorter and is adapted to fit between the lug 5 at one end of the memher 1 andthe lug 19 at the other end of said member 1, the inner face of said lug 5 being preferably substantially perpendicular to the inner face of the member 1, instead of sloping as hereinabove described, and the lug 19 being arranged to project from the inner face of the member 1 beyond the loop 12 and being provided with a notch 20 to receive a lug or projection 21 borne by the end of the member 2 adjacent thereto. By this arrangement, the lugs or

projections

2 and 21 on the ends of the member 2, by seating in the notches 1 and 20 in the

lugs

5 and 19, respectively, borne by the member 1, prevents lateral movement of one mem her with respect to the other. The opening 14 is omitted entirely from the member 2, and the opening 1 1 in the member 1 is arranged to extend also through the lug 19, as best seen in Fig. 10.

It will be evident that a rope clamp constructed as hereinabove described will be strong and eflicient and, furthermore, same will be simple, easy, and inexpensive to manufacture.

We claim:
