Patented Jan. 18, 1949 TROLLEY WIRE HANGER Samuel S. Matthes, `Manseld, Ohio, assignor to The Ohio Brass Company, Mansfield, Ohio, a corporation of NewJersey t Application octber 19, 1945, seriaiNo. 623,216

5 Claims.

My invention relates to supports for trolley wires and has particular reference to those de` vices for supporting trolley wires forming a part of the overhead system for trolley bus operation.

In such systems the parallel trolley wires are placed some 18 to 24 inches apart and of opposite polarity. This requires suflicient and proper insulation between the wires which is one object of my invention.

Another object is to provide means for attaching supporting spanwires to the device and which means is adjustable to compensate for the variable conditions met within overhead trolleyconstructions, thereby permitting proper positioning of the trolley Wires.

Other objects and advantageswill appear `from the following description.

In the accompanying drawing illustrating my invention: y d

Fig. 1 is a side view in partial section of my invention arranged to support two trolley wires.

Fig. 2 is a view in partial section of the end cap I use before application to the connecting bar.

Fig. 3 is a side view showing a portion of the end cap in Fig. 2. y

Fig, 4 is a side view of the adjustable arm I employ.

Fig. 5 is an edge view of Fig. 4.

Fig. 6 is a side view of a special bolt I use` Fig. '7 is an end view of Fig; 6.

My improved hanger is so constructed that variation in the span wiresoused to support the trolley wires, may be easily adjusted such that the trolley wires may be installed and maintained in a horizontal plane at the hanger.

Sometimes the span wires to a hanger are of equal length and sometimes of greatly different lengths and often the `far end of one span Wire is attached to its support at a greater height than that of the other span wire. My invention will make it possible to compensate for such variations.

In the preferred embodiment of my invention I provide a connecting bar I of necessary length whereby the end members 2 may be held in spaced i and insulated relation.

The member I may be of wood or of other approved construction or material. I prefer wood as it has been found dependable and economical.

The end members 2 are cup shaped as shown in Fig. 2 with projecting lugs 3 and 4 forming therebetween the space 5. Both lugs 3 and 4 are provided with registering openings 6 and 'I. The opening 1 is surrounded by a plurality of serrations 8.

The cup shaped member 2 originally and the `ends of the bar I have heads with tapered side Walls and when the members 2 are positioned on the ends of the bar l and the side walls of the member 2 forced inwardly,a

v connection is secured which is equal or better than the minimum breaking strength of the bar.

The arms 9 are secured to the end members 2 in adjustable relation thereto and are so attached to the members `2 that `they may be adjusted in a vertical plane to differ angular posii tions relative to the bar I.

This adjustment is secured by the use of abolt or pintle I0 having the under surface of its head II provided with serrations I2 to correspondto the serrations 8 on the end member 2.

The bolt ID is further provided with an outoi-round shank I3, preferably` square, and projecting from the shank I3 is a threaded portionL I4 to take a nut I5.

Between the head II andshank I3 and between To assemble the arms 9 in the slots scf the end members 2, the arms are first positioned in the slots 5 with the openings 6, 1 and I'I registering. The bolts IIJ are then positioned in the open-` ings with the serrations I2 on the bolt head `cooperating with the serrations 8 onthe lug 4.`

This locks the arms 9 against pivotal movement about their pivotal centers which are the axes of the openings 6 and 'I because the Shanks I|3 are sufficiently long to enter Well the openings I'I` in the arms 9.

Since the opening 'I is round, the bolt IIJ is free to rotate in the lugs 3 and 4 when the serrations are not interlocked. i

When the arms 9 are properly positioned as to their angular relation to the axis of the bar I ,u

then nuts I5 are secured to the projecting ends of the threaded portions I4, employing a spring lock washer, if desired, to prevent its unscrewing.

If at any time it is found thatthe sag of the span wires supporting the device has changed so serrations and'retighten the nuts I5. d l

has straight sides 5 tive to the longitudinal axis of the body. and means to maintain said cooperation between the said one lug and the bolt-like member.

5. An adjustable fitting comprising a metallic member provided with means to secure it to a body member and also having two projecting lugs in xed spaced relation and having axially registering openings but one opening being larger than the other opening, an angularly adjustable arm having one end pivotally mounted in the space between the lugs, the arm having an opening through the said one end and registering with the other `said openings, a pintle slidably positioned in the said openings `and having spaced portions rotatable in the rst `said openings relative to the lugs, means on the pintle intermediate the spaced portions andother means on the arm arranged to cooperate with the said means on the pintle to prevent rotation of the pintle relative to the arm, means on the pintle and means on the outer face of one lug arranged to cooperate with the last said means on the pintle to prevent rotation of the arm and pintle relative to the lugs, and means on the pintle cooperating with the outer face of the other lug to prevent the pintle sliding and to maintain the cooperation of the said means on the pintle and on the said one lug after the arm has been angularly adjusted relative to the lugs.
