SUSPENS ION HANGER Filed Nov. 26, 1952 Z IV/LL/HM f7. BEOCK Mada Patented Mar. 28, 1933 UNITED STATES SUSPENSION HAneEn Application filed November 26, 1932. Serial No. 644,528."

This invention relates to improvements in suspension hangers, and more particularly those used in connection with electric transmission towers to suspend ground .wires.

One object of the invention is to provide a structure which is very durable, highly eflicient and easily installed.

Another object is to provide a suspension hanger adapted to enable a swinging movement of the structure suspended, and yet one which is simple in design and cheap and easy to manufacture.

These and further objects will appear after referring to the drawing, in which: j Figure 1, which is an elevation of an electric transmission employing a single ground wire, discloses one use of the invention.

Figure 2 is a view of a structure similar to Figure 1 but in which two ground wires are used.

Figure 3 is an end elevation of the apparatus of both Figure 1 and igure 2.

Figure 4 is an end elevation of the invention shown partly in section.

Figure 5 is a side elevation of the apparatus of Figure 4.

Figure 6 is a fragmentary detail of the invention.

Referring more particularly to the drawelectric transmission tower which supports one or more ground wires 12. In supports of this sort it is of course a well known fact that the wires must be permitted to sway with the wind, otherwise they will be broken and occasion considerable damage. Numerous attempts have been'made in the past for accommodating this swaying movement, but necessitate considerable expense, and require a 40 heavy and rather complicated structure.

According to the present invention the usual shifiiei or angle beam 3 to which the suspension hanger is to be attached is provided on one side or flange with a hole 3*,

and on the other side or flange with a slot 3'.

Holes 3 are provided at each side of the slot 3 A V-shaped lazy-bolt 4 is disposed with its ends extending through the slot 3 and the holeS on the opposite side of the angle beam I or shifiler 3. Two nuts 5 are threaded onto ing, the numeral 2 indicates a conventional the bolt 4 and contact with the inner sides of the flanges of the angle beam 3. Anut 5is threaded onto theend of thebolt 4 which ex tends through, the hole3 On the'outside of v the opposite flange of thefangle beam '3' a" plate (ihaving three holes drilled therein is positioned with its holes in exact ialineme'nt" withthe slot'3" and'the two holes 3 in the flange. Suitable bolts 7 extend through thev holes 3 in the flange and the associated holes in the plate 6 and are-secured on the outside y nuts 8; A nut 5 is likewise secured tothis endof the V or lazy-bolt 45. f-

A conventional book 9, provided with a I clevis arrangement 10, pivotally supportsa cradle 11in which is disposed a ground wire 12.

It is to be understoodthat 'while the invention is shown as'associated with an'electric transmission tower, it is susceptible of 7d many other uses. v

While I have shown and described one specific embodiment of my invention it willbe understood that I do not wish to be limited exactly thereto, since various modifications may be made without departing from the scope of my invention, as defined in the following claims.

I claim: I V g 1. A suspension hanger comprising an 30 angle beam having a hole in one flange thereof, a slot in the other flange of said angle, beam disposed opposite said hole, a bolt extending through said hole and said slot, a'pair of nuts on said bolt, one on either side of said hole, a nut on said bolt adjacent said slot, a plate having a hole through which the bolt extends from said slot, a nut on the endof said boltand in abutment with said plate, and means to secure said plate to said flangee 2. A suspension hanger comprising an 7 angle beam having a hole in one flange therel of, a slot in the other flange of said angle beam disposed opposite said hole, a bolt extending through said hole and said slot, a 957 pair of nuts on said bolt, one on either side of said hole, a nut on said bolt adjacent said slot, a plate having a hole through which the bolt extends from said slot, a nut' on the end j of said bolt and in abutment with said plate,

PATENT my hand.

means to secure said plate to said flange and a hanger member associated with the midportion of said bolt.

3. In a suspension hanger an angle beam comprising a pair of flanges, a hole in one of said flanges, a slot in the other of said flanges,

a bolt-extending through said hole and said slot, a pair of nuts on one end of said bolt, one on either side of said first named flange, a nut on said bolt adjacent said slot, a plate associated with said other flange. andthrough which theother end of the bolt extends, a nut for said bolt in abutment with said plate, and

additional means to secure said plate to said flange.

4L. In a suspension hanger an anglebeam comprising a pair of flanges, a hole in one of said flanges, a slot in the other of said flanges, abolt extending through said holeand said slot, a-pair of nuts on one end of said bolt, one on either side of said first named flange, a nut on said bolt adjacent said slot, a plate associatedwith said other flange and through which the otherend of the bolt extends, .a

nut for said bolt in abutment with said plate,

additional means to secure said plate to said flange and a hanger member associated with the mid-portion of said bolt.

In testimony whereof, I have hereunto set WILLIAM M. BROOK.
