April 1, M c lS CLAMP Filed Aug. 5, 1929 Mrrzbmmmn ATTORNEY Patented Apr. 1, 1930 UNETED STATES MARION C. MORRIS, F ROSEMARY, NORTH CAROLINA CLAMP Application filed August 5,1929, serial No. 383,493.

This invention relates to new and useful improvements in clamps and more particularly to those forms of clamps designed for holding wires, cords, cables and the like at their points of intersection.

An object of the invention contemplates the provision and arrangement of gripping elements for this purpose.

Another object of the invention consists of adjusting means for the gripping elements whereby the intersecting lines may be disposed at different angles.

More specifically stated the gripping elements are so constructed that the portions of the lines intersecting therein will not be injured incident to the connection or adjustment.

With the above and other objects in view, the invention further consists of the follow- 0 ing novel features and details of construction to be hereinafter more fully described, illus tratecl in the accompanying drawing and pointed out in the appended claims.

In the drawing Figure 1 is a plan view of the invention as applied for use.

Figure 2 is a sectional view taken on line 2-2 of Figure 1.

Figure 3 is a view similar to Figure 2 and taken on line 3-8 of Figure 1.

Figures 4 and 5 are. bottom plan views of the respective gripping elements.

Referring to the drawing in detail wherein like characters of reference denote corresponding parts, the reference characters 10 and 11 indicate the gripping elements of my novel form of clamp having slots 12 and openings 13 respectively designed for registration in a manner to be better understood in the following description of the invention. Both of the gripping elements are provided with semi-circular grooved portions 14: upon the adjacent faces thereof with central depressions 15 to facilitate accommodation of the lapped or intersecting portions of lines or cables. This method or means of association is clearly shown in Figure 3 of the drawing.

As generally known in line work, the precaution is generally taken to tighten same to an appreciable extent at different heights in order that one line may not rub against the other to scrape the insulation therefrom after the lines have become stretched and sag.

- The degree of tension upon the lines is such,

especially where long lines are used, that it is necessary to provide the supporting standards with forms of guy wires in order that the standards may withstand the tension and maintain the lines in taut condition. The 160 slots and openings 12 and 13, previously re ferred to, are registered to facilitate accommodation of the shanks 16 of forms of fastening generally designated as at 17 having embossed shoulders18 diametrically opposed upon the undersides of the heads therefor to prevent turning of the shanks while the nuts 19 mounted upon the opposite and tapped ends of the shanks are being screwed-home. The slots 12 will afford adjustment to the gripping elements 10 and 11 whereby lines may be joined in the manner shown at different inclinations or pitches. Where several lines cross and are secured together at their points of intersection in the manner suggested by the present invention, the draft action upon the supporting poles therefor may be slackened to an appreciable extent due to the fact that it will be no longer necessary to exercise such tension upon the lines to sustain same in positions spaced from each other to prevent beating, rubbing or chafing. It is, of course, obvious that this form of clamp may not be utilized for the joining of charged power lines in view of the fact that considerable interference would be set up.

The invention is susceptible of various changes in its form, proportions and minor details of construction, and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having thus described the invention, what is claimed is l. A clamp for intersecting lines comprising a pair of gripping elements, said elements having line receiving grooves and central depressions to accommodate the intersectlng portions thereof, and means establishlng connection between said elements to bind the immediate and intersecting portions of the lines therebetvveen.

2. A clamp for the intersecting portions of lines comprising complemental gripping elements, each of said elements having line receiving grooves and intersection receiving depressions upon the adjacent faces thereof, said elements having registering slots and v openings respectively, and fastening means passed through the openings and slot and coacting with the latterto facilitate adjustment and accommodation of the clamp upon lines intersecting at different angles.

In testimony whereof I afiix my signature.

MARION C. MORRIS.
