31 claims. (01. f191 37) This invention relates to a trolley wire posi-E tioning member and has special reference to trolley cross-overs, switches, frogs and the like.

More particularly, this invention relates to a two-piece trolley wire positioning member-com prising an upper or supporting portion which is adapted to be permanently attached to the crossing or connecting trolley wires and a lower por-' tion which is adapted to be easily removed when such is desirable. y With cross-overs, switches and the like, made in one piece, as is generally done, if any part is defective or becomes worn the whole device must be removed and replaced. Furthermore, the means usually employed for securing the cross-overs, switches and the like in position with respect to the trolley wires comprise clamps, bolts and nuts, thereby making it-quite an operation to fasten or remove these members.

The present device provides a two-piece trolley positioning member in whichthe upper or supporting portion is adapted to be permanently at tached to the trolley wires, it being only necessary to remove. this portion when the trolley 25,, wires are themselves taken down or replaced. This upper portion may be provided with novel means whereby it may be easily and quickly attached to the trolley wires without the use of any clamps, bolts or the like. Alower member which includes thetrolley runners and approaches is adapted to be positioned under thefupper member and secured in place by merely clamping the approaches over the trolley wires. With this construction, the .lower member which receives the greatest wear may be easily removed by merely spreading the clampedends of the approaches. H 1 l An object of this invention is to provide a twopiece trolley wire positioning member in which the upper portion is adapted to be permanently attached to the Wires while the lower portion which receivessubstantially all the wear may "be easily removed and replaced. e

A further object of this invention is to -provide a trolley .wire positioning member having novel securing means and which .may be easily and securely attached to the trolley wires without the use of securing-clamps, bolts andthe like.

A still further object is to provide aconstruc tion which will gradually damp the vibrations o1 5 latter:

Referring more particularly to the drawings, the construction shown in Figs. 1 to 7 comprises an upper member 1 which may have crossed arms 2 and 3 The upper cross'arm member 1 may be provided with upwardly bowed channels 4 and 5, the channel 5 extending upwardly above the channel 4 so that the trolley wire 6 will cross above the trolley wire '7. Notches or slots 8 may be provided in the arms 2 and ,3 adjacent the outer ends of the upwardly bowed channels 4 and 5. These notches 8 extend inwardly" from the sides of the arms and are formed on opposite 1 sides of the arms so that all the slots extend into the arms in either a clockwise or counter-clockwise direction.

Downwardly extending curved portions 9 having channels 10 in the bottom sides thereof may be formed at the outer ends of the upper cross arm'member 1 and are preferably formed integrally' withthe upper member] 1. With this construction to fasten the upper cross arm ,mernher 1 to the crossed trolley wires ,6 and '1, it is only necessary to slide the trolley wire 7 inward ly in the slots 8 so that the wire lies inthe up} wardly bowedv channel 4 and the channels 10 in the downwardly extending curved j portions 9.. The same operation .is' then repeated with re} spect to the other trolley wire and-.- the arm .3. When thus attached, the upper memberl is lower POrtion I portion/1'1 andjare providediwith downwardly 29. In order to hold th. upper portion 17 n';

clamped together over. the trolley wires.

securely fastened to the crossed trolley wires and no further securing means are necessary.

The lower crossarm member 11 comprises a central portion or plate 12 which'may be in the form of a cross. U-shaped trolley runners 13 having'approach portions 14 are secured to the lower sideof the plate 12 with the open side facing upwardly. Any means may be employed for fastening the runners 13 to the plate 12 .such as riveting the plate to outwardly extending flange portions 15 of the runners 13 or they may be formed integrally with the plate. When the approach portions 14 of the runners 13 are peened or clamped about the trolley wire, the rigidly constructed lower member .serves' to gradually dampen the vibrations of the trolley wire as the vibrations progress toward the plate orv central portion thereby eliminating vibration points where the .wire tends to crystalize and eventually break. is especially true if the wire is deadendedasfj'shown in Figs. 8 to 13. A lug 16 may be secured to the plate 12 between the inner ends oftherunners13 by any desirable means. This lug 16 serves to guide" the trolley between the inner. endsof the runners 13. To secure the lower member 11 to the upper 'member 1 after the latter hasbeen properly fastened to the'trolley wires,

the lower member 11 is positioned under the? up- 7 per member 1 so that the downwardly extending curved portions 9 will fit between the upwardly extending sides of the runners 1-3. The upper sides of the approach portions 14f are then This securely holds the lower portion'fll in place and willprevent any movement thereof with respect to .-theyupper por tion 1.

' Although the cross-over is shown and described as having the arms rigidlyfixed at right angles to each other, it is evident'that the arms may be placed at any angle' or may be adjustable. This construction may also be used with any number ofz-arms to take care of two or' more crossing trolley wires.

- 9 Figs. 8 to 13.show a trolley switch or frog em bo'dyin'g'the present invention' This switch or frog comprises anupper orsupporting member 1'1, which may have a longitudinally extending. upwardl'y'bowed channel18 with slots 19 extend- 1 in'g'iinwar'dly from opposite sides of the supporting member 17 adjacent the ends of the upwardly bowed channel 13. These slots 19, as well as the slots, 8 previously described, are cut at an angle to thejplane ofthe supporting members 1 and 17 ,sotha't the edges thereof will not cut or wear the trolleyl'wire's at, the point of contact. Downwardly extendingcurved portions 20, similar to ,me downwardly extending curved portions 9 may be secur'edjtothe under side of the supporting facing channels" 21. Trolley wire 22 would be positioned'with respect to the supporting member 1'1 in the manner 'previouslyjdescribedinpositioning'thecross-over. I v

The .connecting,trolley wire 23 may be positioned in'the channel 24. in thebottom or the outwardlyexten'ding portion '25 ofthe supporting portion 17 and is then bent' up through the slot 26 jaftenwhich it. is doubled 'back on top of the poftion25 and secured by the plate 2'1 which is clamped over, the end thereof by means of nuts 28 threading onto the upwardlyextending bolts place and usethe same as a strain plate; ears 3 0 cured.

a may be providedto which guy'fwires maybe se-j 7b e f 'tion 11 of the cross-over to the upper portion The lower portion 31 of the switch or frog may comprise a guide plate 32 having runner.

portions 33 extending outwardly therefrom which are adapted to engage the trolley wires. I Approach portions 34 are provided on the end of the runners 33 and are preferably formed integrally therewith. The lower portion 311s secured to the upper portion 17 in amanner similar. to that employed in fastening the lower por- 1. The downwardly extending curved portions 20 fit between the upper sides of the runners 33 and the approach portions 34 are then clampedover the trolley wires.
