SPECIFICATION forming part of Letters Patent No. 541,557, dated J une 25, 1895.

Application led September 29, 1894- v Serial No. 524,474. (No model.)

To all whom it may concern:

Be it known that I, ANDERS WILHELM LEWIN, commercial agent, a subject of the King of Sweden and Norway, and a resident of Tegnrlunden 8, Stockholm, in the Kingdom of Sweden, have invented certain new and usefulimprovements in automatic mechanism for rapid catching and disconnection ofl tus arranged as a boat-belaying cleat. Figs. 2

and 3 are respectively a top view and an end view of the same, and Fig. t represents a modification of the same apparatus.

The apparatus destined to be a boatcleat Fig. l consists of the casing L in which the gripping jaws A are pivoted, which are actuated by springs K located between them and the inside of the casing. By means ot' screws passing through the screw-holes b, the 'apparatus may be fixed in asuitable position with relation to the sheet or rope, which shall be fastened. The upper detachable wall a of the casing is divided in two parts opposite the opening between the jaws, and the two halves of the wall are at a distance from each other somewhat greater than the thickness of the sheet or rope for which the cleat is destined. The said opening facilitates thus the introduction of the rope or the sheet from the side between the jaws A which then, owing to the pulling at the sheet, pinch this latter between them. At the pinching, the drawing out of the sheet between the jaws is pre- Vented by hooks c projecting from the edges their hold on the rope.

In order to produce a uniform and simultaneous motion of the'jaws theseare connected with each other by means of a plate vd displaceable 0n the undivided wall of the envelope L and provided with two slots e into which enter pins g projecting from the jaws A through slots f. It will be easily understood how, by means of the described arrangement motion may be transmitted from the one jaw to the other.

Fig. 4 shows a modification of the connection lastvmentioned. The slot plate d is in this casel substituted by a bow h the legs of which are displaceable in the casing L each leg being moreover, as shown in the drawings, pivoted toits respective jaw. The principal purpose with this bow is to facilitate the disconnection of the sheet, which is effected by introducing the bow toward the casing when the jaws Aare turned so as to let go The arrangement last mentioned may be of use on many occasions.'

In combination in a rope clamp, the pivoted jaws, the casing inclosing the same, and the plate sliding-in the bottom of the casing and connecting the jaws, substantially as described.
