11 and 16 and are providcd with a central perforation 23, through which the threaded ends of the clamping bar 1% extends, which bar, through nuts 2&, 25, may be clamped firmly against the cross arm, thus holding the bracket in a defined position.

The blocks 19, 20 are of tapered form so that whatever the position of the clamping bar in the horizontal or vertical. position, the nuts 'will bind firmly and squarely against the upper surface of the tapered blocks. The taper of the block of course corresponds to the incline of the perforated boss and when the nuts are once firmly screwed down with the bracket adjusted upon the cross arm, the tendency is to bind tighter and tighter under any given strain. In Fig. t the

bosses

30 and 31 are illustrated as having faces substantially at right angles to each other.

The perforations 33 are ofelongated form so that an adjustn'ient'of the clamping bar ill may be ei'l'ected in two directions, thus permitting adjustment to cross arms of various cross sections. As in the device heretofore described, a universal adjustment is thus preivided, but in lieu of the tapered or wedge-shaped members underlying the nuts 36, @T, rectangular blocks or washers 3S, 3!) are employed. This form of the device, while of somewhat simpler form, lacks the inclined form of binding surface of Figs. 1 to :3 and. will not have the inhercntclamping action toward the angle of the bracket when setting down the binding nuts. ()t' course, the clamping bar is capable of adjustment in two directions and if snugly fitted and tightly clamped, provides a substantial holding device with the features (it mljustability.

In the -form described in Figs. 1 to 3, the tightening of the nuts tends to draw the bracket firmly against the cross arm as the clamping bar is tightened in both directions. It will be noted that the webs of the bracket are of substantial width so that a firm hold or seat is given for the bracket with reference to the cross arm, thus unusual strains may be placed upon the insulators without liability of the bracket turning or becomingdisplaced and without liability of its cutting into the material of the cross arm. Y

Obviously, the exact form of bracket and arrangement of insulators might be varied to a great extent without departing from the spirit or intent of the invention and in lieu of having two arms with threads for supporting insulators, a single arm either dependent and similar to the arm 7 or extending upwardly as the arm 5 might be used. In fact, the arrangement or insulator supporting arms is immaterial, the essence of the invention residing in the arrangement of the bracket having a saddle with a clamping bar universally adjustable with reference to the two parts of the saddle, whereby it may be adjustable with referenceto-and secured to cross arms of various cross sections.

What I claim as my invention and desire to secure by Letters Patent is:

1. An adjustable insulator support having means for supporting an insulator embodying a saddle part comprising two members angularly disposed to embrace two sides of a cross arm, tapered bosses arranged on each of said members, said bosses having their-tapers ext-ending toward each other, a. clamping bar arranged to embrace two sides of the cross arm and having its ends projecting beyond the tapered bosses of the saddle member and devices for drawing the clampii'ig bar to cause said bar and saddle member to bind against the cross arm.

2. An adjustable insulating support having means for supporting an insulator embodying'a saddle comprising two members angularly disposed to embrace two sides of a cross arm, bosses having elongated perforations arranged on each of said members, said bosses having angularly disposed faces, perforated binding blocks fitting said tapered faces, a clamping bar extending through the perforated bosses and binding blocks and devices for drawing said clamping bar through said bloc-ks.

S. In a device of the character described, a; saddle-like member having angularly arranged extensions embracing two sides of a cross arm, tapered bosses having elongated perforations arranged in each of said extensions, perforated blocks of wedgeshape overlying said perforated bosses and provided with dependent flanges embracing the sides thereof, a clamping bar having its ends protruding through said wedge-shaped blocks and nuts engaging the ends of said clamping bar.
