7 Claims.

My invention relates to improvements in devices for use with overhead trolley wire systems; and the objects are to provide an approach, end member or tip which may be detachably secured to overhead devices of various types and be readily replaced when worn and to provide a continuous guide surface for current collectors passing from the wire onto the device to which the improvement is attached and vice versa.

I attain these objects by the construction illustrated in the accompanying drawing, in which-- Fig. l is a side view of my invention as applied to an-end portion of an overhead trolley device.

Fig. 2 is a top view of Fig. 1.

Fig. 3 is an end view of Fig. 1.

Fig. 4 is a side view of my improved end or tip shown in Fig. 1.

Figs. 5A, 5B, 5C, 5D and 5E show sections on the lines A, 'B, C, D and E respectively of Fig. 4.

Fig. 6 shows a section on the line 6-6 of the tip shown in Fig. 1, after the lips shown in Fig. 5 have been formed about the trolley wire.

This application is a division of my co-pending application, Serial No. 56,973, filed December 31, 1935.

In the preferred embodiment of my invention I provide a tip of metal having a tongue portion l adapted to be positioned in a slot or groove forming part of the device to which the tip is attached. The tongue is provided with transverse openings 2 to receive means for securing the tip in position relative to the attached device.

Projecting from the tongue I is a portion having a rib 3, and an open groove 4 of varying depth formed by the bendable lips 5 and 6 varying in depth.

In Fig. 6 the lips 5, as for instance, at the sections CD, are shown clinched in position on the trolley wire I. It will be noted that'the lower edges of the lips meet a considerable distance below the trolley wire, thus leaving a space 8. This construction permits the trolley wire to be brought up over the end 9 of the device to which the tip is attached and at the same time the closed lower surface of the tip is in alignment with the lower edge of the trolley wire device to which the tip is attached, thus the trolley shoe or wheel makes a smooth and uninterrupted passage from the tip to the attached device and vice versa.

At section B, Fig. 4, the lips are of such length as to just encircle the wire 1 which at E, Fig. 4, the lips 5 are spaced apart the diameter of the wire but the vertical direction of the recess within the lips is much greater as shown in Fig. 6.

The lips 6 shown in Fig. 5A are arranged to grip the trolley wire in the grooves with which most trolley wires at the present day are provided. If, however, the wire is round or some other shape the lips will be arranged accordingly.

lips 5 and the construction of the portion bearing I the lips 6 are so arranged that the lower surface l I of the trolley wire I will be in alignment with the lower surface l2 of the lips when closed and will in turn be in alignment with the lower surface of the device to which the tip is attached. The end face l3 of the lips 5 abuts against the end face of the attached'device.

The lower face 14 of the tongue I is tapered to better correspond to the angle which the trolley wire will assume in its transition from the tip to the attached device.

The aforesaid trolley wire device is formed preferably of metal and has intermediate its ends means to hold the wire in position.

Having disclosed my invention, I claim:

1. A tip for a trolley wire device comprising a body having a tongue portionto receive means for securing the tip to the device, a portion projecting from the tongue in alignment with the tongue, one edge of the projecting portion provided with a wire-receiving groove open throughout its length along one edge, one portion of the groove formed by lips of uniform depth and another portion of the groove formed by lips of varying depth, the lips of varying depth being adapted to have their free edges formed together to enclose the wire and form a guide surface for a current collector and also form a wire-receiving passage. of varying depth.

2. A tip for a trolley Wire device comprising a body having a tongue portion adapted to be at lips forming the other portion of the groove being bendable along their free edge to meet and form the last said portion of the groove into a passage of tapering cross-section through which the trolley wire passes.

3. A tip for a trolley wire device comprising a body having means for attachment to the device and means projecting from the attaching means in alignment therewith, the projecting means being provided with spaced lips forming a groove open along one side only to receive a trolley wire therebetween the lips decreasing in length along one end of the projecting means towards the other end thereof and adapted to be bent inwardly along their free edge until the edges abut forming a passage of tapering cross-section between its ends to receive the trolley wire, the

passage being of the same dimension at one end as that of the wire and of a greater dimension at the other end in one direction than that of the wire but of the same dimension as the wire in the other direction.

4. A tip for a trolley wire device comprising a body having means for attachment to the device and means projecting from the attachment means in alignment therewith, the projecting means being provided with spaced lips forming a groove open along one side only to receive a trolley wire therebetween, the lips being of decreasing depth for a portion of the length thereof along one end of the projecting means, the lips decreasing in depth toward the other end thereof and adapted to be bent inwardly along their free edge until the edges abut forming a guide surface for a current collector and also forming a passage of tapering cross-section between its ends to receive the trolley wire, the said guide surface being in alignment with the lower surface of the trolley wire held in the groove of the said first portion.

5. The combination with a trolley wire of a supporting tip for the same, the tip having means to secure it to an overhead trolley wire device and other means projecting therefrom, the latter means having an open groove formed by spaced lips along one edge and in which groove the trolley wire may be placed, the lips being bendable about the trolley wire to enclose the same and the abutting edges of the lips forming a guide for a current collector, the passage formed by the bent lips having a diameter at one end equal to that of the trolley wire and having a dimension in one direction at the other end greater than the diameter of the trolley wire.

6. A trolley wire device comprising a body member provided with a grooved end adapted to receive a trolley wire, a tip member secured to the body-member and having a tongue positioned in the groove and therein securely held, the tip member also having a projecting portion provided along one edge with an open groove formed by spaced lips of varying depth adapted to receive the trolley wire, the lips arranged to be formed about the trolley wire after the wire is positioned in the groove to form a passage within which the wire rests, the diameter of the passage at one end being that of the wire and the other end of the passage having a dimension greater in one direction than the diameter of the wire, the lower portion of the formed lips acting to guide a current collector from the trolley wire onto the said body member.

'7. A trolley wire support for application to a trolley wire without breaking the continuity of the wire comprising an elongated member adapted to form a part of an overhead system and to guide a moving current collector over a portion of the system, means associated with the elongated member intermediate its ends to engage the trolley wire and hold it in place, the elongated member having a clevis at one end to receive the trolley wire and hold it in alignment therewith, detachable means having a portion positioned in the clevis and the other portion projecting therefrom in alignment therewith to receive the trolley wire and hold it in alignment with the guiding edge of the said member, the detachable means provided with a groove formed of bendable lips to receive the trolley wire and the lips when bent forming a passage about the wire of varying size whereby the wire is permitted to pass upwardly and through the aforesaid clevis and the lower surface of the formed lips is in alignment with the guiding edge of the member and acts to guide the current collector from the wire onto the elongated member.
