ROPE-CLAMP.

SPECIFEGATION forming part of Letters Patent No. 734,469, dated July 21, 1903. Application filed January 3, 1903. Serial No. 137,664. (No modelJ To all whom, it may concern.-

Be it knownthat I, ARTHUR ADELBERT NEWELL, a citizen of the United States, and

a resident of Mellette, in the countyof Spink and State of South Dakota, have invented a new and Improved Rope-Clamp, of which the following is a full, clear, and exact descrip-- that is to be joined to the rope whereon the clamp is mounted and which may be used in various other connections, as will hereinafter appear.

The invention consists in the novel construction and combination of parts, as is hereinafter described, and defined .in the appended claims;

Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective View showing the application of the improvement. Fig. 2 is a partly-sectional side view of the rope-clamp and hook adjusted toclampa rope. Fig. 3 is a like view, with the exception that parts are adjusted to release a rope, the latter being indicated by dotted lines. Fig. 4 is. an enlarged perspective View of a latch-dog that is a novel detail of the invention, and Fig. 5 is a side view of the clamp seen in direction of the arrow 00 in Fig. 2.

The body of the rope-clamp is preferably cast into form from metal, and consists of an essentially tubular shell 6, convexed near one end on its exterior and having an essentially corresponding concavity a on the same wall opposite the convex surface.

An elongated opening b is formed in the shell 6 diametrically opposite the concavity a, the edges of the shell that define said opening being preferably sloped downwardly and two opposite inwardly-projecting sharpened spurs c are formed,-as is clearlyindicated by full and dotted lines in Fig. 5. 'On the concave wallof the shell 6, near the hook .7, three spaced spurs d are projected inwardly, said spurs being suitably spaced apart, as shown in Fig. 5.

From the upper termination of the sloped edges 6' the wall ofthe shell is converged somewhat, so as to diametrically reduce the open end, which receives the rope end A when the device is to be mounted thereon.

At or near the upper ends of the side edges 1), that define the width and length of the opening bin the shell 6, a .latch'dog 8 is held to rock, as is clearly shown in Figs. 2, 3, and 5. The dog 8 comprises an essentially L- shaped block of metal, which maybe shaped as shown in Fig. 4, havingits two angularlydiverged members 8 8 braced at their junction by the web-wall 8.

A transverse perforation e is formed in the latch-dog 8 at the junction of the members 8 and 8", and two opposite perforations are formed in the wall of the shell 6 to receive a pivot e, which when secured therein afterinsertion'through the perforation 6 will dispose the members 8 8 projected inwardly and free to receive rocking adjustment.

A preferably V-shaped notch g is formed in the free end of the member 8, and a like notch h is produced in the free end of the member 8 of the latch-dog 8. Preferably the member S is of somewhat greater length than the member 8 and the longer member of the latch-dog may be rocked, so as to project it out of the shell 6 or be disposed within the same as shown in the drawings.

In the application of the device to a line or rope for service the latch-dog'S is adjusted as shown in Fig. 3, which will afford a clear passage through the shell 6 for the'insertion of the rope A therethrough; When the shell I00 6 is positioned on the rope A at a desired point, the latch-dog 8 is rocked, so as to press the member 8 against the rope A and force the latter into contact with the side of the shell that is opposite the dog.

The partial rotation of the longer limb or member 8 in the direction of the arrow at in Fig. 3 by pressure on it, whereby to introdoes the shorter member 8" within the shell 6, as described, serves to rock the longer limb 8 into contact with the rope A, as shown in Fig. 2.

From the relative positions had by the members 8 S of the latch-dog when it is adjusted as shown in Figs. 1 and 2 the rope A will be pressed toward the concavity a in the shell 6 and be forced into engagement with the spurs a (Z therein, which will prevent the shell 6 from slipping on the rope, and it will be seen that if the rope is held at a point above the shell and dra t't force is applied to the hook 7 the limb S will be rocked into closer engagement with the rope and clamp the shell 6 tighter upon the rope.

From the foregoing it will be manifest that the angularly-bent latch-dog 8 eliteets the automatic locking of the shell 6 and hook 7 upon the rope A by merely pressing the dog member 8 as a lever from the position shown in Fig. 3 to that indicated in Fig. 2.

When it is desired to release the clamp from the rope, the shell 6 is grasped and the rope also below the shell and held while the shell is pressed upward. This will rock the dog 8 slightly on its pivot and correspondingly move the dog member 8* outward from the shell, so that it maybe taken hold of and rocked more fully outward or into the position shown in Fig. 3, which will release the clamp from the rope.

The improvement may also be utilized for a rope-clamp with any desired attachment theretosuch, for example, as with a ring,

"(eases a snap-hook, a swivelsnap, or a swivel, as may be desired.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A rope-elamp, com prising a shell having an elongated opening at one side extending through the lower end thereof, a rearwardlyturned hook at the lower end of said shell forming the termination thereof, the shell having a concavity on its rear side opposite the lower end of the elongated opening, spurs in the concavity, and an L-shaped dog pivoted to rock at the upper end of the elongated opening with its short arm normally extending transversely of the central opening of the shell to engage the rope therein and its longer arm extending downwardly in said elongated opening at the side of the shell, to a point opposite said spurs, and adapted to swing into engagement with the rope to clamp the same into engagement with the spurs, the free ends of the L-shaped dog being each pro: vided with a large notch adapted to embrace a portion of the circumference of the rope to more firmly engage the same.

2. A rope-clamp, comprising an elongated shell having an opening in one side extended to one end thereof, and also having a concavity near said end opposite the opening, spurs in the concavity near each end thereof, an integral hook on the shell below the concavity, and a substantially L- shaped dog pivoted atits angle in the shell at its opening, said dog having its members notched at their free ends to engage a rope.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ARTHUR ADELBERT NEWELL.
