INSULATED ADJUSTABLE TROLLEY-OROSSING.
ley-crossings, and it consists in the novel.
insulated, adjustable trolley-crossing which we shall hereinafter fully describe and claim.
The object of our invention is to provide a simple and effective trolley crossing, the
intersecting angle of the members of which.
may be varied to suit the location of its use, one ofsaid members carrying a through or continuous trolley wire and the other being provided with insulating connections to receive the severed ends of the other trolley wire.
Referring to the accompanying drawings-Figure 1 is a top view of our crossing. Fig. 2 is a sectional elevation parallel with the insulating member 1. Fig. 3 is a bottom View of the crossing. Fig. 4 is a view parallel with the through member 2, one portion being in elevation and the other in section, the clamping nut 9 being omitted on the .right hand side, the sliding clamp 8 alone being shown.
The crossing comprises two intersecting members 1 and 2. These may be fashioned for any form of trolley, both alike, or one different from the other. In the present instance for illustration wehave shown the member 1 as fashioned with bottom runners for the pantagraph type of collector, and the member 2 as adapted for the ordinary trolley wheel.
Application filed March 18, 1911.
Patented Dec. 5, 1911. Serial No. 615,269.
call the through member (terming, for like reasons, member 1 as the insulating member) has the lower surface ofits turntable 4 grooved out as shown in Figs. 2 and 3, to form a diametrical running rib 6 which alines with and continues the lower surface of the arms of said member and which forms the runner for the trolley wheel, so that said trolley wheel may continue without interruption in contact with the entire length of said member.
As seen in Figs. 2 and 3, the bottom runners of the insulating member 1 terminate at theperiphery of the turntable 4 of the through member 2. The upper side of the through member 2 is channeled out as shown at 7, and in this channel the through trolley wire 16 is to be carried, the channel being so shaped as to carry said wire across the 1 upper face of the turn-table 3 of the insulating member 1, as seen in Fig. 4:. The trolley wire may be securedin its channel by any suitable form of clamp. We have here shown sliding clamps 8 seated in the arms of said through member and adapted to be pressed down upon the wire being clamped in their seats by nuts 9 one of which is shown in Fig. 4 on the left, the nut on the right being omitted. 1
The insulating member 1, is formed with abutment flanges 10 where its arms join its turn-table, and the said arms are adapted to receive the wood breaks 11, which consist of wooden blocks, the inner ends of which lie against the abutment flanges 10 and their outer ends extend beyond said member to a safe distance To the outer ends of these wood-breaks, the severed ends of the other trolley wire are to be attached. The wood-breaks are secured in place by suitable means, as, for example,
' by the lugs'or ears 12 formed on the arms of the member 1 and adapted to receive bolts 13 which pass through the wooden blocks.
14; is a tie-plate which is bolted to and eX- tends between the abutment flanges 10, and 15 is a tie-plate which is bolted to the upper inner ends of the arms of the crossing member 2, both tie plates bridging the space above the turn-tables and serving to strengthen the members.
From the foregoing description it will be seen that the crossing is an adjustable one, in that the angle of intersection of its members may be determined to suit the place no I of its use, and is an insulated one in that one of its members is let into its trolley wire through the intervention of the wood breaks.
Having thus described our invention what we claim as new and deside to secure by Letters Patent is- 1. An insulated adjustable trolley-crossing comprising intersecting crossing members, each formed with a turn table superposed one on the other and adjustably pivoted together, that one of said members which has the underlying turn table being fashioned to receive a through trolley wire and to carry it across the overlying turn table of the other member, said underlying turn table being formed on its lower surface with a diametrical running rib continuing the under surface of the arms of the member of which it forms a part; and the other member having its arms formed with run ners on their lower surface which terminate at the periphery of the turn table of the first named member, the lower surface of said runners lying in the plane of the lower surface of the turn table of said first named member; and insulating blocks secured upon the upper surfaces of the arms of the second member and projecting beyond their extremities, the lower surfaces of the projecting portions of said blocks continuing in the plane of the runners of the arms of said second member.
2. An insulated, adjustable trolley-crossing comprising intersecting crossing members, each formed with a turn-table interfitting and adjustably pivoted together, one
of said members being channeled to receive a through trolley wire and to carry it across the turntable of the other member, and provided with means for holding said Wire in place; and the other of said members having abutment flanges on each side of its turn-table and its arms formed with ear lugs on each side; and wooden blocks seated on said arms against the abutment tlanges and bolted to said arms through the ear lugs.
8. An insulated, adjustable trolley-crossing comprising intersecting members, each formed with a turntable interfitting and adjustably pivoted together, one of said members being channeled to receive a through trolley wire and to carry it across the turn-table of the other member, and provided with means for holding said wire in place; and the other of said members having abutment flanges on each side of its turntable and its arms formed with ear lugs on each side; wooden blocks seated on said arms against the abutment flanges and bolted to said arms through the ear lugs; and tieplates bolted to the inner ends of the arms of the crossing members and bridging the space above the turn-tables.
In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
