Application led December 12, 1908. Serial No. 467,240.
To all whom it may concern:
Be it known that l. lViLLann ll. Keur- 'ro), a citizen of the vUnited States, residing at lrlartford, in the county of Hartford and State of Connecticut, have invented a new and useful Trolley-lire Hanger, of4
which the following is a specification.
This invention relates to a hanger which is designed to mechanically grip and support a vtrolley wire, messenger wire, or other wires or cables used in overhead electric railway systems.
The object of the invention is to provide a strong hanger with simple parts which are cheap to nninufacture and easy to assemble, and which so constructed that the heavier the weight or downward strain, the tighter the clalnp will grip and hold the wire or cable.
Figure 1 of the accompanying drawings shows a side view of a hanger which ein bodies the invention. Fig. shows a side elevation of the toggle which is designed to hold the. clainp plates together. Fig. 3 is a central vertical section of the hanger. Fig. -t an end view of the hanger. 5 is a perspective view ot' the toggle hohling block which is located between the clamping plates. Fig. G a perspective view of one of the toggle links.` Fig. T is a perspective view looking at the inside of one of the clamping plates. Fig. S shows a vertical section of the hanger with the supporting rod arranged so as to perniit of a vertical yielding of the hanger and trolley wire. Fig. 9 shows a central vertical section of a hanger with the holding rod arranged in another manner which allows a vertical yielding of the hanger and wire.
The hanger illustrated is particularly designed to clamp and hold a grooved trolley wire 1, although the invention is applicable for suspending trolley wires having other cross sectional shapes, and for supporting other wires and cable of an electric system.
The clamping plates 2 which are shown in the drawings are formed similar in outline, of any suitable metal, with jaws 3 valong their lower edges shaped to grip a grooved trolley wire, and with recesses 4 at their upper edges which permit the passage through them of the supporting rod 5.
Between the clamping plates, which are hol- 'i low for the purpose, is a. block (S having a threaded perforation into which the. end of the supportingl`-- rod is screwed.
rl`he toggle links T of the hanger shown, extend through openings 8 in the clamping plates and are pivoted on a pin 9 which is held by ears projecting froin the block. The outer ends of the toggle links are provided with bars l() that, when the parts are assembled, rez-tt in recesses l1. in the outer faces of the claiuping plates. A nut 12 is turned upon the threaded end of the supporting rod in such inanner that it may be screwed down against. the upper edges of the clainping plates.
After a trolley or other wire or cable has been located between the clamping plates the nut is turned down against the upper edges of the plates. This draws the block and inner ends of the toggle links upwardly between the plates, which action closes the toggles and causes the toggle bars on the outside to pull the clamping plates tightly together. The harder the nut is turned down on the supporting rod against the edges of the clamping plates, the tighter the toggle bars draw the plates together and cause thein to grip the wire or cable between thein. The weight of the suspended wire itself, when the clamping plates are engaged with it, tends to draw the. plates down with relation to the supporting rod and the block with which it is connected, and this causes the toggle to draw and hold the plates together. The parts cannot be disengaged and the wire released until the nut is loosened. But when the nut is loosened the toggle is relieved so that the plates can be separated and disengaged froin the wire.
For the purpose of allowing the hanger to yield, the supporting rod can be provided with a head 13, which n'iay be arranged in a casing 14E that is provided with a nut 15, into which the end of a continuation of a hanger rod 1G may be screwed, as shown in Fig. 8. Another method of providing for a vertical yielding of the hanger and wire is to extend the shank 17 of the toggle block upwardly between the upper edges of the clamping plates and through the nut 18, as shown in Fig. 9. In this case the nut is screwed upon the shank of the toggle block until it bears against the upper edges of the clamping plates, which action causes the toggle to draw the plates together. The shank of such a toggle block may be provided with a socket 19 adapted to receive a head 20 of the supporting rod 2l. A cap 22 may then be screwed upon the end of the shank of the block so as to hold the head of the supporting rod in the socket.
The invention claimed is:
l. A hanger having clamping plates, a toggle block located between the plates, a support for said block, toggle links carried by the block and adapted to draw the plates together, and a nut arranged to force the plates and the toggle in opposite directions, whereby the toggle will draw the plates toget-her.
Q. A hanger having clamping plates, a toggle block located between the plates, toggle links pivoted to the block and extending through the plates, means connected with the toggle links and bearing against the outer sides of the plates, and means for forcing the toggle block and the plates in opposite directions with relation to each other.
A hanger having clamping plates, a toggle block located between the plates, a toggle pivoted to the block and adapted to draw the plates together, and means for drawing' the toggle block upwardly with relation to the plates.
il. A hanger having clamping plates, a toggle engaging and adapted to draw the clamping edges of the plates together, and
means for causing the toggle to draw the plates together. Y
A hanger having clamping plates, a block located between the plates, a toggle pivoted to the block and adapted to hold the plates together, a rod adapted to support the toggle block, and a nut threaded on said rod and adapted to force the plates and thetoggle block in opposite directions.
6. A hanger having a pair of plates, a block located between the plates, a toggle pivoted to the block and ext-ending through the plates and bearing on their outer surfaces, a rod connected with the block and extending between the plates, and a nut threaded upon the rod and adapted to force the plates and the block in opposite directions,
7. A hanger having clamping plates, a toggle hinged between the plates and having bars bearing` against the outer surfaces of the plates, and means for causing the toggle to draw the plat-es together.
8. A hanger having clamping plates, a toggle engaging and adapted to draw the clamping edges of the plates together, means Ifor causing' the toggle to draw the plates together, and a support connected to and having a limited vertical movement independently of said toggle actuating means.
