CABLE-CLAMP.

Specification of Letters Patent.

Patented Feb. 19, 1918.

Application filed April 9, 1917. Serial No. 160,794.

To all whom it may concern:

Be it known that I, Manna OLSON, a citizen of the United States, residing at Mount Vernon, in the county of Skagit and State of Washington, have invented certain new and useful Improvements in Cable-Clamps, of which the following is a specification.

This invention relates in general to cord and rope holders and more particularly to a cable clamp.

The primary object of the invention is to provide a clamp which will efiiciently hold a plurality of cables in spaced relation.

Another object is to provide a clamp including a support having a locking key associated in cotiperative relation therewith to retain a plurality of cables in a clamped position upon said support.

A further object is to provide a clamp which is so constructed as to firmly grip a cable without mutilating the same.

The above and other objects will be more readily seen from the following description and accompanying drawings.

In which drawings:

Figure 1 is a side elevation of my improved clamp showing the application thereof.

Fig. 2 is a top plan view and Fig. 3 is a cross sectional view taken on line 3-3 of Fig. 1.

In the drawings the numeral 1 indicates a block or cable support the configuration of which is substantiallv similar to that of an inverted cone. It will be noted that the block is formed with a small end 2 and is flared outwardly therefrom to provide a broad upper surface 3 the latter having the inwardly curved retaining arms 4 and 5 nositioned on opposite margins thereof. The ends of the retaining members are recessed intermediate the lateral margins thereof as indicated at 6 and shown to advantage in Fig. 2. A centrally disposed tapered recess 7 is formed in the block 1 and communicates with an opening provided in the lower end 2. A retaining key 8 is provided which consists of the enlarged head 9 equipp d with the depending shank 10 the latter being shaped to be received in the recess 7 and provided with a threaded bore 11 which in assembled position, registers with the opening formed in the lower end of the block, The threaded shank of a bolt 12 is inserted through the opening formed in the lower end of the block 1 and is adapted to be received in the threaded bore 11 of the key 8. By rotating the bolt 12 the key 9 is slidably adjusted in the recess 7 for the purpose of tightening or releasing the grip on the cables.

In practice, a pair of cables are arranged upon the blocks 1, each cable being positioned beneath one of the retaining mem bers 4L and 5 respectively. The shank of the key 9 is then inserted in the recess 7 and the enlarged head of said key is received in the recesses 6 as shown. The bolt 12 is then inserted in the opening in the lower end of the block, and is properly engaged with the bore 11 of the said locking key. Thus it will be seen by turning the bolt in one direction the enlarged head of the retaining key will be clamped firmly against the cables while operation of the bolt in the reverse direction will release the grip upon said cables.

I have thus fully described the preferred form of my invention but do not limit myself to the exact construction set forth but reserve the right to make such changes as may come within the scope of the claims without departing from the spirit of my invention.

What I claim is:

1. A cable clamp. including a block having a recess formed therein and provided with an opening communicating with said recess. retaining arms formed on said block, a retaining key adapted to be received in said recess. said retaining key being equipped with a bore registering with said opening, and a locking member engaged with the bore of said key.

2. A cable clamp including a block, inwardly curved arms formed on said block and a retaining key adapted to operate between said arms for clamping cables be tween said key and under said arms.

3. A cable clamp including a block, inwardly curved arms formed on said block, said arms being provided with recessed ends. and a retaining key adapted to operate between said arms and .in said recess for clamping cables between said key and under said arms.

4. A cable clamp including a block, inwardly curved arms formed on said block,

said arms being. provided With recessed ends, a retaining key adapted to operate between said arms, said key having an enlarged head adapted to be received in said recess in said arms for clamping cables under the curved ends of said arms and the enlarged head of the key.

In testimony whereof I afiix my signature in presence of two wltnesses.

MANIE OLSON.
