UNITED STATES PATENT rarest AXEL LEVEDAIIL, OF AURORA, ILLINOIS.

CLAMP FOR CROSSED WIRES.

SPECIFICATION forming part of Letters Patent No. 583,654, dated February 5, 1895.

Application filed November 26, 1894. Serial No. N model-l To all whom it may concern:

Be it known that I, AXEL LEVEDAHL, of Aurora, in the county of Kane and State of Illinois, have invented certain new and useful Improvements in Clamps for Crossed \Vires; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to an improved metal clamp for use in rigidly securing together rods or wires in crossed relation, and it has for its object to provide a device of the character referred to simple in construction, convenient of application, and which forms a more rigid, durable and better finished fastening than those heretofore employed for similar purposes.

The invention is especially adapted for use in forming a rigid and durable connection between the crossed spokes of light steel or iron wheels, as bicycle wheels and the like, but may also be advantageously used to fasten together intersecting wires of metal net or grill work, and for various other analogous purposes. 7

The invention consists in the matter hereinafter described and more particularly pointed out in the appended claims, and the same will be more readily understood by reference to the accompanying drawings, in which Figure 1 is a view in side elevation of the clamp as formed ready for application. Fig. 2 is a perspective view of the same. Fig. 3is top plan view. Fi 4 is a side elevation of the clamp applied to a pair of crossed rods. Fig. 5 is a plan view of the same.

Referring to said drawings, A designates the clamp or clip as a whole. It may be formed of sheet metal, out into suitable blanks and struck up by means of a suitable die.

As shown in Figs. 1, 2 and 3, which illustrate the form of the clamp before application,it has oppositely arranged side walls a a which diverge from each other from the middle portion of the clamp toward each end thereof, the diagonally opposite portions of which, as a a and a a are arranged to stand in parallel planes. The side walls a a are joined by an irregular shaped convex bottom portion a, the unclosed clamp having the form as a whole of two open ended, U-shaped channels a a arranged to intersect each other at the desired angle, and one of which, as a is deeper or has its bottom arranged in a plane below that of the other a distance equal to the diameter or thickness of one of the rods designed to be clamped therein. The other or shallower channel a is, therefore, interrupted by the deeper channel, its bottom comprising only end portions of a". The depth of the channelsa' ando, and the contour of the margins of the sides on forming said channels are such that when applied in the first place to the wires B B to be clamped, it fits against one side of both wires, and, when wrapped or formed about the wires, the edges meet, and it thus forms a clamp or X- shaped sleeve which completely embraces the intersecting rods throughout the length of said clamp.

It will be obvious that the contour of the meeting edges of the clamp may be varied somewhat, it being of course understood that what ver is taken off or deducted from one margin must be added on the opposite margin, but I have found in practice that the form herein illustrated is the preferable one. As herein shown, one of the diagonally opposite portions, or those which are arranged to stand in parallel planes, as a a are somewhat wider at their outer ends than the opposing portions er a and slightly rounded or convex at their upper margins. Both the portions a a? and a a are wider at their ends than at the middle portion of the clamp in order to compass the diverging wires, and it is to be noted that the form of the clamp may be varied considerably to suit the requirements of the different angles of intersection of the rods or wires to be clamped, it being obvious that the greater the angle at which the rods cross the longer must be the end margins or greater the circumference of the ends of the clamp in proportion to the circumference of the center thereof.

The clamp in its open form having been placed upon the crossed wires so that the latter rests in the bottoms of the channels a a the opposing edges of the clamp are brought together or formed over them by any suitable tool or die, thus forming a complete clasp, as

shown in Figs. i and 5. After having been properly applied, the clamp may be plated or otherwise finished if desired.

For neatnessof appearance the end margins of the clamp are herein shown as slightly rounded or chamfered.

A clamp constructed in accordance with myinvention may be applied with the greatest facility, is extremely simple and cheap of construction, and forms a strong, neat and rigid fastening peculiarly adapted to successfully withstand the severe strains to which a fastening of this character is subjected, especially when applied to the spokes of bicycles or similar wheels.

I claim as my invention 1. The combination with wheel spokes which cross each other at an acute angle, of a connecting clamp for uniting the same, consisting of a single piece of sheet metal which is bent to form two intersecting tubular parts or sockets located in different planes, both of which sockets embrace the spokes at both each end thereof, joined by an irregular shaped convex bottom portion, forming in conjunction with said divergent sides two U- shaped channels of unequal depth intersecting each other at an acute angle and adapted to be clamped about, and when so clamped, to fit and retain two crossed wires or rods at their intersections, substantially as set forth.

In testimony that I claim the foregoing as my invention I affix my signature in presence 40 of two witnesses.

AXEL LEVEDAHL.
