suspended by Wire or wires eXtendinglongi--- tudinally or transversely of the trolley Wire or track.
An important object of this invention is to provide a device of the above mentioned character, formed of few and simple parts, which may be readily assembled and separated, and Will not be liable to accidents, such as the disconnection of the parts thereof or of the trolley Wire held by the same.
A further object of this invention is to provide a trolley Wire clamp, which may be used in connection with either a trolley wheel or sliding shoe contact device.
A further object of the invention is to provide a device of the above mentioned character, which can be assembled, inst-alled, or taken apart without loss of time, can be manufactured at a small expense, and is durable under the conditions usually found where a catenary or other trolley Wire construction is employed.
Other objects and advant-ages of this invention will be apparent during the course of the following description.
In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a.
perspective view of the clamp, Fig. 2 is a transverse sectional view taken on line 2-2 of Fig. 1, showing the trolley and Suspension wires held thereby, Fig. 3 is a side elevation of the clamp with the transverse bolt in section, Fig. l is an elevation of the inner side of one of the clamping members, showing a Suspension strap employed in connection therewith, Fig. 5 is a perspective view of the transverse bolt, and, Fig. 6 is a similar view of the suspension strap, the upper portion thereof being broken away.
In the drawings, Wherein for the sake of illustration, is shown a preferred embodiment of my invention, the numeral 10 desig- :natesvmy improved 1 rtrolley 'Wire ola-mp as a whole,y`
comprising oppositely arran'ge'd clamping plates 11, which are identical. At
-theirr lower h'endsfthe clampin'g plates '11 are providedrwith recesses 12, formin'g contract- -edfJaWs 13 to holdfa portion of a 'trolley wirexjll, a's'shown. Ati-theirE upper ends, the
One clamping plate 11 is provided through its central portion with a transverse opening 21, which is square in cross-section to receive a square portion 22 of a transverse clamping bolt 28. IThis clamping bolt is provided with a screW-threaded end portion 24,' extending outwardly beyond the opposite clamping plate 11. Arranged upon the screW-threaded portion 24: is a nut 25, engaging a Washer 26. As shown in Fig. 2, the clamping bolt 28 serves to clamp the plates 11 into engagement with the suspension Wire 18 and the trolley Wire 14 whereby these plates may be readily separated and assembled by proper manipulation of the single clamping bolt.
It is often desirable to suspend the trolley clamp by means of a strap 27, which may be inserted through the Vertical opening or openings 19, to extend into the space 20, as clearly shown in Fig. 4:. The strap 27 is provided at its lower end with an opening 28 to receive the clamping bolt 23. The strap 27 is provided at its upper end (not shown) with suitable means whereby the same may be connected With transverse suspension wires or other supporting means.
In the use of the trolley clamp, the same may be suspended by either the longitudinally extending cable 18 or the strap 27. In
either case the trolley Wire 14 is gripped be tween the jaws 13 and is suspended thereby.
VThe clamping plates 1-1 are drawn 'together Vby proper manipulation of the nut 25.
' claim.
Having desoribed my invention, I claim tially centrally thereof with alined transverse openings and at their upper ends with inwardly projecting extensions having reserving to prevent one plate from being turned upon the bolt with relation to the other and having its end apertured to receive the bolt.
In testimony whereof I aflix my signature 'in presence of two witnesses.
