ROPE-CLAN P.

SPECIFICATION forming part of Letters Patent No. 722,949, dated 1V.[arch. 1"i, 1903.

Application-filed November 25,

To all whom zit ntcty concern: I,

Be it known that I, Fn DERio'K O, Onowrr, a citizen of the United States,'residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful. Improvements in Rope-Clamps, of which the following is a specification.

The object of this invention is the prod uction of a device for securely gripping a rope.

I0 It is adapted to be used in rope halters, in suspending hammocks, and in many other connections.

In the accompanying drawings, Figure l is a perspective view of this improved ropeclamp in position upon a rope, the key or clamping member being shown separate from the body portion of the clamp. Fig. 2 is a longitudinal section through the body portion of the clamp and the locking member, showing the latter within the body portion, but not turned to its clamping position. Fig. 3 is a similar view showing the position of the parts when the rope is clamped by the turning of the key or clamping member into its clamping position.

In the construction of this rope-clam p I provide a body portion A, comprising astraight side A, longitudinally perforated in the opening A Continuing said straight side A and at the ends of the latter are the two integral upwardly-inclined end portions A and A provided with perforations A and A, respectively, through both of which openings the rope to be held is intended to pass. .At

5 the sides of the side portion A are two forwardly-exten din g integral ears A and A the former being provided with a keyhole A and the latter with a coinciding circular opening A. In one side of the key hole I form a small 0 notch A and on the inner side of the ear A and adjacent to said notch I provide an integral stop-lug A B refers to a key orclamping member having a straight cylindrical stem portion 13 and an angular shank portion B provided with an eye B at its end. The shank portion is reinforced by an integral web 13, and the cylindrical portion B is provided with an integral cam projection B extending substantially at right angles with the plane of the shank portion of the locking member B. A

, fiat spring 13 is secured to the side of said cam projection, the free end of said spring being adapted to enga'gewith the stop-lug A on the ear A of the body portion A. 5 5 0 represents a rope, one end of which is passed through the loop B and secured therein in any suitable-manner." The intermediate portion of said rope extends through the openings A and A of the body portion A. To adjust the position of the body portion of the clamp upon the rope, the latter may be slid through the openings A and A in the body portion by raising the part of the rope between said openings into a loop and pulling the slack from the loop to one side or the other of said body portion. To do this, the clamping member B is first removed from the body portion A. When the rope is in position in the body portion, as indicated in Fig. 7o 1 the cylindrical portion B and cam projection B of the locking member may be insorted into the body portion through the keyhole A", the forward end of said cylindrical stem portion B resting within the'circular opening A in the ear A In inserting the locking'member B through the keyhole the spring B is pressed closely against the side of the cam projection B and whensaid looking member is in position within the body portion A the free end of said spring pressing againstthest'op-lug A tends to throw the cam projection'B out of coincidence with the keyhole. The rope is clamped in position by turning the locking member B upon its cylindrical shank portion, throwing the cam projection B into contact with the rope C, deflecting said rope into'the opening A in the side portion A of the body portion A. When the parts of the rope-clamp are in engagement with the rope C to clamp the latter, the cam projection B5 of the locking member Bis thrown slightly overits center, tending to prevent the accidental displacement of the locking member. The angle between the cam projection B and the shank B of the locking member may be increased, if necessary, in order to increase the security ofthe clamp in its locked position. The spring B tends to hold the cam projection B away ice from the keyhole to prevent the lockin g member B from dropping out of its seat in the body portion A. When it is desired to with draw said locking member, the spring 13 is compressed against said projection 13 by turning the locking member B and the latter withdrawn from the body portion. In practice the friction existing between the rope O and the body portion A is snfiicient to hold the rope without the engagement of the cam projection B.

It is apparent that the retaining-spring B might be omitted and that various other changes might be made in the general form and arrangement of the several parts of this rope-clamp without departing from the spirit and scope of my invention, wherefore I do not intend to limit myself to the precise details herein set forth.

I claim as my invention- 1. In a rope-clamp, in combination, a plate having upwardly-inclined ends, each of said ends being provided with an opening through which a rope is intended to pass, the walls of said openings forming bearing-surfaces for said rope; and a locking member having a cam projection adapted to press said rope toward said plate at a point between said openings.

2. In a rope-clamp, in combination, an integral body portion having a side portion, the ends of said side portion inclining upward and being each provided with an opening, through which openings a rope is intended to pass, and an intermediate opening; and a locking member having a cam projection adapted to have a rotative engagement with said body portion, said member being adapted to press the rope into said intermediate opening. c

3. In a rope-clamp, in combination, an integral body portion having a side portion provided with two openings into one of which and out of the other of which openings a rope is intended to pass, the walls of said openings forming bearing-surfaces for said rope, and an intermediate opening; and a locking member having a cam projection adapted to have a rotative engagement with said body portion and being adapted to press the rope into said intermediate opening to bind said rope against said bearing-surfaces.

4. In arope-clamp, an integral body portion having a side portion provided with two openings into one of which and out of the other of which openings a rope is intended to pass, the walls of said openings formingrbearingsurfaces for said rope, said body portion also having two ears extending therefrom, one of which ears is provided with an opening; in combination with a locking member adapted to be inserted into the opening in said ear, said locking member having a cam projection adapted to deflect the rope at a point intermediate the openings in said side portion to bind said rope against the walls of the openings in said side portion.

5. In a rope-clamp, an integral body portion having a side portion provided with two openings into one of which and out of the other of which openings a rope is intended to pass, the walls of said openings forming bearingsurfaces for said rope, an intermediate opening, and two ears extending from said side portion, one of which ears is provided with an opening; in combination with a locking member adapted to be inserted into the opening in said ear and to be rotated with reference to said ears, said locking member having a cam projection adapted to deflect the rope into the intermediate opening in said side portion.

6. In a rope-clamp, in combination, a side portion having two openings through which a rope is intended to pass; two ears extending from said side portion, each provided with an opening; a locking member adapted to be inserted into the openings in said ears and to be rotated with reference to said cars; a cam projection on said locking member, adapted to deflect the rope at a point intermediate the openings in said side portion; and means for normally preventing the withdrawal of said locking member from said ears.

7. In a rope-clamp, in combination, a side portion having two openings through which a rope is intended to pass, and an intermediate opening; two ears extending from'said body portion, each provided with an opening; a stop-lug on one of said ears near the opening in said ear; a locking member adapted to be inserted into the openings in said ears and to be rotated with reference to said ears; a cam projection on said locking member, adapted to deflect the rope into the intermediate opening in said side portion; and a spring on said cam projection, adapted to engage said stoplug to prevent the withdrawal of said locking member from said ears.
