curing the ends ofy ropes, especially where' the. rope is turned about an o en thimble which is designed to be retaine securely in the bight thus formed.v

It consists in the combination of arts and details of construction, which l be more fully eX lained by reference to the accompany-ing rawings, in which- Figure 1 is a sectional view showing 4my device as ap lied to a rope in" conjunction Fi 2' is transverse enlarged section throug a: :v of Fig.` 1. Fig. l3 1s a view showing the application toop osite ends of a rope to make aslip-noose. IFig. 4 is an end view of the device.

' A represents a ro e of 'any description.

2 is a thimble ci) the usual construction having a fperpheral concaved groove or channel aroun which the bight of the rope is itted, and 3`is the socket piece or device for interlocking the main portion of the rope and the end after the latter is passed around the thimble. This socket-piece 3 has made walls taper in form from one end lof the socket-piece to the other. These channels are separated by the convergent central'diaphragm 6, this ortion having walls converging toward the end where the twoportions of the rope enter and to which -the thimble 4is contiguous. The diaphragm 6 terminates a sufhcientdistance from the endl of the socket-piece 3 so that the two parts of the rope A cross each other above the thin edge of the diaphragm and within the socket-piece 3. The advantages of crossing the rope in this manner are, first, that by crossin the rope the two lparts of the rope are ma e to follow the diminishing end of t e thimble and to it snugly in its peripheral groove to its very point or termination without the need of an exterior means for producing such a resu t; secondly, the twist or lay of the 4rope is such that the strands of the two crossing parts of the rope follow each other, and thus interlock, so as to'hold these parts of the rope very rmly in osition.

The opemng', into which the terminal end ofthe rope passes, has .its walls made divergent, an the strands of the rope beingllsepli.-y p t` 's 'i rated or broomed out will loosely openlng and may be very firmly lockedin ace by a plug which maybe very suitably orme`d by pouring melted metal into the divergent opening to iill in a space around the strands. are very generally use in logging, where it is Wire ro es of this description` desirable to form a running noose, so that v the rope can be passed around alog or other part to be moved and power applied to the opposite end. For this urpose I app thimble and holding attac ent to eac end of the rope, the thimble at one end being 'suflicientl larger than that at the other end yto allow t e smaller one and its socket-piece 3 to easily pass through the larger one, as plainly shown in Fig. 3,

Having thus described my invention, what I claim, and desire to secure by Letters Patly aj 1. .A rope-clamp having in combination a socket-piece whose inner wall'dverges substantially from one end to the other, a diaphra within said piece and dividing the interior of said piece into two channels, a thimble disposed near the smaller end of the socket-piece, said diaphragm extending from the lar er inner end of the socket-piece to a point s ort of the smaller outer end, and a rope passing around said thimble and having its two parts entering the smaller outer en of the socket piece, said parts of the rope crossing each other in the smaller end of said socket-piece above the outer end o' the diaphragm whereby thestrands of the rope interlock at their crossing-point.

' -2. The 'combination with a socket-piece having an internal diaphragm which divides its interior into two channels, the inner wall of the socketepiece diverging from substantially one end of the socket-piece to the other,

' said diaphragm having its outer end terminating within the socket-piece, a thimble dis osed contiguous to the outer end of the soc et-piece, and being made taperin in shape -toward the smaller end of the soc retpiece, and a rope passing around the thimble and having its two parts entering the smaller IOO or outer end ofthe socket-piece and crossing In testimony whereof I have hereunto set each other therein above the outer end ofthe my hand in presence of two subscribing Witlo diaphragm whereby the rope is itted closely nesses. 4 y
