ROPE-CLAMP.

Specification of Letters Patent.

Patented Mar. 5, 1918.

Application filed January 30, 1917. Serial No. 145,505.

To all whom t may concern.'

Be it known that I, DAVID J. LAssrrER, a citizen of the United, States, residing at Ci'essinont, in `the county of Lee and State of Kentucky, have invented new and useful Improvements in Rope-Clamps, of which the following is a specification.

The present invention relates to improvements in stop clamps for ropes or cables, and the primary object of the invention 1s to produce aii article of this character which may be readily applied to the rope, easily adjusted thereon and effectively secured thereto.

With the above and other` objects in view the improvement resides in the construction,

combination and arrangement of parts set forth in the following specification and falling Within the scope of the appended Claim.

In the drawing:

Figure 1 is a perspective view illustrating the application of the improvement,

Fig. 2 is a central longitudinal sectional view through the improvement, and

Fig. 3 is a transverse sectional view approximately on the line 3-3 of Fig. 2 and looking in the direction of the arrow.

My improvement can be employed upon a rope for any number of purposes, as for instance, to form a stop member for the rope so that the same can be engaged in a bifurcated member such as a cleat, etc., or so that the same provides a stop to permit Vof the easy handling of the rope, as for instance, when it is desired that the rope be drawn manually in one or both longitudinal directions, and also for other purposes wherein stop lugs are desired upon a rope or cable.

In carrying out my improvement I provide a barrel 1 which is preferably round in cross section and which has its bore at one of its ends threaded, as at 2, and the said bore being flared or cone-shaped from the terminal of the threads, as indicated by the numeral 3. Within the cone-shaped bore I arrange a pair of similar clamping members Each of the clamping members has its outer surface flared to conform with the ared portion 3 of the barrel 1, and the inner or confronting surfaces of the said clamps are provided `with rounded depressions 4* extending the entire length of the said clamps. The clamps, of course, provide wedge members and when the same are drawn outwardly of the flared bore 3 the in rope gripping engagement, I provide an adjustable member 6 having a reduced threaded portion 7 which is adapted to engage with the threads 2 in the barrel 1, and it will be apparent that by screwing the said member inwardly of the bore of the barrel l,

the end thereof will contact with the outer and widened ends of the clamps 4 to force the said clamps outwardly of the flared bore and toward each other and consequently into tight gripping engagement with the rope or. cable 5. The member 6 at its outer enlarged or shoulder portion is provided with a plurality of angular faces or walls 8, whereby the saine may be readily screwed within the barrel or unscrewed therefrom either b hand or with the assistance of a suitable too such as a wrench.

Having thus described the inventiomwhat I claim is: y

A rope stop clamp comprising a cylindrical body having smooth exterior' surfaces, an end surface of the body lying in a plane at a right angle to the axis of the body, the said body being provided with a centrally located smooth conical bore the smaller end of which opens at that end of the body which is )rovided with said piane surface whereby t e solid portion of the body is rendered transversely thicker a't the plane of said surface than at an other transverse line, the body being provided at its opposite end portion with an internally located thread, semi-cone shaped clamp members fitting within the said bore with their outer surfaces in close contact with the conical surfact` of the bore, the edges of the said clamp members being spaced from each other, said members being provided at their inner sides with longitudinally disposed channels which are arcuate in transversev sections, smooth and less in diameter than the diameter at the smaller end of the bore, and an externally threaded member adapted to engage the thread of the body and having a central opening of greater diameter than` the diameter of the channels of the clamping members.

In testimony whereof I aix my signature.

DAVID J. LASSITER.
