BONDNG DEVICE FOR RAILS.
Specification of Letters Patent.
Patented Sept. 28, 1915.
Application filed June 23, 1913. Serial No. 775,276.
To all whom t may concern.'
Be it known that I, ALFRED A. ZinGLE-R, a citizen of the United States, residing at Boston, in the county ot' Sutt'olk and'State lof Massachusetts, have invented an lnr provernent in Bonding Devices for Rails, of which the following is a siiecitication.
This invention relates to bonding-devices for rails. It is the common practice to attach the ends of the bond-wires to the. rails and to form large loops which extend over the tie-plates. These loops are unsupported except at their' ends and are very objectionable on account of the liability oi' being broken, and in such event the signal-circuit is disrupted. Heretofore means have been devised for supporting the bond-wire loops between their ends, but either the wires are concealed for a substantial portion of their length and hence do not admit of immediate inspection, or they are connected with the tieplate or with the attaching-means tor the tie-plate in such manner as to inter-'tere therewith and cause trouble, particularly between the men who have chargel of the track, and the men who have charge of the signal-system, and, so 'far as l am aware no support for a bond-wire loop has ever been adopted.
This invention has for its object the construction of an improved form of support for a bond-wire loop which is adapted to support the loop in such manner that it is exposed throughout its length for inspection, and while not interfering with the tieplate or the attaching-means therefor, may serve to hold the bond-wire in electrical engagement with the tie-plate for additional security.
My invention includes a special form of attachingbolt which is utilized as a support kfor the bond-wire loop, said bolt having' formed entirely across the under side of its head one or more grooves adapted to receive the bond-wire and admit of a slight turning movement of the bolt, and having formed on its shank below its head an elongated boss adapted to 'enter the elongated taken on the dotted line Fig. 1. Fig. 3 1s an enlarged transverse vertical section taken on the dotted luie I-f, Fig. 1. Fig.
et is an under side view of the head of the attachingsbolt. Fig. 5 is an under side view of a Inodiiied form of attzu'hing-holt. Fig. G is a detail of a modification to be referred to.
10, l() represent the end-portions of the 'railsg l2 the tie-plate which is secured thereto by attiuzhing-bolts l. and l5 the bondwire which is attached at its ends to the endportions of the rails. and which is formed as a loop. The head of the attaching-bolt has one or more grooves 20, see Fig. 4, extended entirely across its under side, said grooves being made at least as wide as the diameter ot' the wire at its n'iiddle, and much wider at its ends, so as to lloosely receive the wire, and also admit of a slight turning movement of the head when the wire isarranged in the groove. Said grooves are made o'll a depth correspoiuling approxi# mately to the diameter of the wire; and in Fig. 3 they are shown as ota slightly less depth than the diameter of the wire, and in Fig. 6 of a slightly greater depth than the diameter ot the wire. when the grooves are made ot a slightly less depth than the diameter of the wire the head impinges -upon the wire and affords an additional contact with the wire and holds the wire in lirni engagement with the tieplate, thereby establishingr an electrical connection which is ot' importance in case the wire breaks at a poil beyond or between the attachingbolts. lv'hen the grooves are inadeof a slightly greater depth than the diameter of the wire the bond-wires may be remo-ved for the purpose of repairing them or new bond-wires may be placed in position without disturbing the attaching-bolt. To prevent the bolt from being turned while the' nut is being tightened or loosened an elongated or oval-shaped boss 25 is formed on the shank of the bolt beneath the head which substantially corresponds in size and shape with the elongated or oval-shaped hole in the tieplate, thereby to admit of its entering said hole in the tie-plate. T he bond-wire, when thus suliported. will` be eX- posed substantially throughout its length.
1. A support for bonding wires interme- .fliate their terminal rail connections, including tie bolts for securing the fish plates in rail engaging position, the heads of one or niore of said bolts being formed in the surface' next the ish plate with channels to nels to form a bond Wire receiving opening open only ai; the endsavnd through which the wires may be'threeded Without; disturbing the bolts.
2. support for bonding Wires intermediete their terminal rail connections, including tie bolts for securing fish plates'in rail engagingposition, the heads of one or more of Seid bolts being formed in the surfaces neXt the ish pla-tes With channels to receive the intermediate portions of said bonding Wires, one Wall of each of said chanln estiniony whereof, l have signed Inyj naine to this speclioation, 1n the presence of v J@Wo subscribing Witnesses. l
