WITNESSES INVENTOR FRED H. DANIELS, OF WORCESTER, MASSACHUSETTS.
RAIL-BOND.
Specification of Letters Patent.
Patented March 9, 1909.
Application filed October 16, 1906. Serial No. 889,148.
To all whom it may concern:
Be it known that I, FRED H. DANIELS, of Worcester, Worcester county, Massachusetts, have invented a new and useful Imrovement in Rail-Bonds, of which the follbwing is a. full, clear, and exact description, reference being had to the accompanying drawin s, forming part of this specification, in whic- 1- Figures 1, 2, 3 and 4 are horizontal sections taken through a rail and showing different forms of my invention.
This invention has relation to the class of rail bonds, its object being to secure the very best possible contact between the heads of the rail bond terminals and the rail, in order to prevent the entrance of moisture between the joint of the copper and steel, to thereby prevent galvanic action, which in any case destroys the eiliciency of the electrical contact.
'ith this object in view, the invention consists in the novel construction, arrangement and combination of arts all substantially as hereinafter described and pointed out in the appended claims.
in the drawings, the numeral 2 designates a rail bond having the terminal head 3, which is soldered to one face of the rail 4, as indi cated at 5. This head is formed with a tubular sleeve 6, which extends entirely through the rail and pro'ec-ts a short distance at the o posite side. itted telescopically around t ie tubular sleeve 6 is a sleeve 7 having ahead 8, which is soldered to the op )0- site side of the rail as indicated at 9. he opening 10 through the rail is of tapered or conical form, the exterior of the sleeve 7 having a corresponding taper, and an initial s ace 11 being left at the inner end of said s cave and around the sleeve 6.
l2 designates a pin, )referably of steel, which is driven through t e sleeve 6, thereby explanding the parts and filling or substantla y filling the space 11. In this manner the electrical contact is not made to depend wholly upon the soldered terminals.
The form shown in Fig. 2 is similar to that in Fig. 1, with the exec tion that the sleeve 6 has a ortion 6' of re uced diameter to receive t e telescoping sleeve 7' of the head or flange 8. In this case also the taper of the hole thI'Ollfil'l the rail and of the outer sleeve is not einp eyed.
The form shown in Fig. 3 is similar to that shown in Fig. 2, exec t that it illustrates a double bonding, both eads or terminals being carried b a bond 2, as shown.
The form s IOWI! in Fig. 4 is similar to that shown in Fig. 1, except that the sleeve 6 is made solid, the pin 12 being omitted. in this case the sleeves are expanded b means of a suitable tool or compressor. 'l is solid construction of the inner sleeve may be applied to all the forms shown.
The advantages of my invent-ion consist in the efticient electrical contact which is secured by the expansion of the telescopin sleeve members against the rail, combined with the feature of the double flanges, which effectually exclude the entrance of moisture between the copper and steel surfaces.
What I claim is 1. A rail bond comprisiu two telescopic members engaging the rai from opposite sides and having each a flanged head whose inner face is soldered to the rail; substantially as described.
2. A rail bond comprising two telescoping member's inserted through an opening in the rail from the opposite sides thereof and expended in said 0 ening,said members having flanged heads so dared to the rail on op osite sides of its web to form moisture-cite uding joints of high electrical conductivity; substantially as described.
3. A rail bond terminal, consisting of two terminal members telescoped with each other from opposite sides of the rail and within its web, said members being expanded into engaggiment with the walls of the opening in the we through which they pass, and each memher having a surrounding flange at its outer end whose inner surface is soldered to the web; substautiall as described.
In testimony w iereof, I have hereunto set my hand.
