To all whom it may concern.

.Be it known that I, KARL ARNSTEIN, a citizen of Czechoslovakia, residing at Friedrichshafen-on-the-Bodensee, Germany, have invented certain new and useful Improvements in Wire and Rope Clamping Devices, for which I have filed an application in Germany October 21, 1921, and of which the following is a specification.

My invention has reference to clamping means for wires, wire ropes and the like, and it particularly provides for the passing of the wires or ropes substantially or approximately or exactly through the median line of the coupling. In accordance with my invention, the wire or rope to be tightened or the wires or ropes to be intersectingly connected or coupled with each other or with other parts are passed between oppositely concave and convex curved clamping surfaces so as to be deflected.

This application is a division of my application for patent filed October 23, 1922, Serial No. 596,488.

The clamping surfaces may be formed of complete discs provided with sector-shaped projections and sockets, the outer surfaces of which are spherically curved in opposite sense, and engaged with each other. The clamping members are connected to each other by several screws, eccentrically arranged, in such a manner that the wires are passed between the two screws at the desired angle, recessed portions being provided for the passage of the wires between the apexes of the projecting sectors. 7 The clampin device according to my invention ofl'ers t e advantage that the wires are held fast along an extended clamping surface and are maintained between only two clamping members, each of the wires being passed between the gaps presented by the projection of one of the members and between the projections of the other member. This aifords the possibility of constructing a coupling device of very compact form requiring very little space. The clamping means, according to my invention, is adapted both for the clamping in position of single or several wires or the like running in one direction only, as well as for the reception of a plurality of crossing or intersecting wires It is particularly adapted for special purposes, forexamplein the building of hulls for air-ships of the'rigid type,'wherein wires, wire ropes and the like aregto be secured to sheet metal members, flange bars and the like.

In the drawings afixed to this specification and forming part thereof, a device embodying. my invention is shown by way of example. In the drawings- Fig. 1 is a side view, the clamping members being shown somewhat separated from each other.

Fig. 2 is a cross section on the line IIII in Fig. 1, and

Fig. 3 is a perspectiveview, the clamping members being separated.

Referring to the drawings, each of the two clamping discs a and a is provided with projecting sectors 1) and b, respectively, the outer surfaces of which are spherically curved and which are adapted to engage in corresponding recesses 0 and 0 respectively, of the other clamping member, the bottoms of the gaps being spherically curved in conformity therewith. The curvature of the segmental surfaces determines the bending of the wire to be gripped, as shown for instance in Fig. 1 of the drawing. The Wires to be clamped or coupled are arranged to extend each across the gaps or recesses of one and the sectors of the other clamping member, a gap y separating the convexshaped sectors of each member.

The clamping members are pressed against one another by a pair of screw bolts 6 with nuts 7, the bolts being fixed in one of the members with about one half of the circumference of the foot portion of each bolt, extending through a semi-cylindrical groove 03 provided in a lateral face of a sector of this member, while similar grooves are provided in the lateral faces of thesectors of the other member for the reception of the free ends of the screw bolts.

Fig. 1 shows the way in which the wires can be fixed by means ofthis device to a plate 9 or to a strut girder or the like.

The particular configuration, relative position and cooperation of the several parts of the novel device allows clamping or coupling a pair of intercrossing wires, ropes or the like right in the diameters of the coup- I ling discsfvvith the Wires-or the like inter- Wires, ropes and the like, comprising in com- V bination, tWo substantially disc-shaped coupling members, convex surfaces on each disc with two oppositely disposed concave recesses, the CODVQX portions of each disc fitting in the concave recesses of the other disc, a central gap between the convex portions of each. disc means for clamping said discs together. 1

2. Clamping and coupling device for Wires, ropes and the like comprising in combination -tWo substantially disc-shaped couplin members, convex surfaces on'each disc witi two oppositely disposed'concave recesses, the convex portions of each disc fitting in the concave recesses of the other d sc, a central gap between the convex portions of each disc and screw bolts extending through said discswith part of their circumferences surrounded by grooves in diametricallyoppositelateral faces of said convex portions.

In testimony whereof I aflix my-signature.
