Definitions
- This invention has for its object to improve the construction of rail-bonds, to the end that a bond of large current-carrying capacity may be constructed which will occupy but little space, so that it may be placed between the fish-plate and the rails and attached to the web of the rails, although it may be otherwise disposed and attached to other portions of the rails.
- the invention consists in a rail-bond having a flexible intermediate portion and circular bolt-receiving loops at the ends thereof which are formed integral therewith.
- the bolt-receiving loops may be offset .relatively to the intermediate portion by bending the ends of the intermediate portion at an angle to the end loops occupying planes in parallelism with the intermediate portion, and in such case the bolt-receiving holes in the rails are counterbored to receive the offset end loops of the bond.
- the rail-bond is preferably composed of a single strip of copper wound upon itself, and the several layers composing the end loops are soldered together, while the several layers composing the intermediate portion remain unattached.

WILLIAM GRANT STUART, OF NEWBURYPORT, MASSACHUSETTS, ASSIGNOR TO CHASE-SHAWMUT COMPANY, OF NEWBURYPORT, MASSACHUSETTS, A CORPORATIONOF MAINE.
RAIL-BOND.
Specification of Letters Patent.
Patented Dec. 12, 1905.
To (ZZZ whom, it 7%007 concern:
Be it known that I, WILLIAM GRANT STU- ART, of Newburyport, county of Essex, State of Massachusetts, have invented an Improvement in Rail-Bonds, of which the following description, in connection with the accompanying drawings, is aspecification, like characters on the drawings representing like parts.
This invention has for its object to improve the construction of rail-bonds, to the end that a bond of large current-carrying capacity may be constructed which will occupy but little space, so that it may be placed between the fish-plate and the rails and attached to the web of the rails, although it may be otherwise disposed and attached to other portions of the rails.
The invention consists in a rail-bond having a flexible intermediate portion and circular bolt-receiving loops at the ends thereof which are formed integral therewith. The bolt-receiving loops may be offset .relatively to the intermediate portion by bending the ends of the intermediate portion at an angle to the end loops occupying planes in parallelism with the intermediate portion, and in such case the bolt-receiving holes in the rails are counterbored to receive the offset end loops of the bond. The rail-bond is preferably composed of a single strip of copper wound upon itself, and the several layers composing the end loops are soldered together, while the several layers composing the intermediate portion remain unattached.
Figure 1 shows in side elevation a rail bond embodying this invention, the fishplate being broken away. Fig. 2 is a plan view of the railbond. Fig. 8 is a vertical .section of the rail-bond and one of the rails,
taken on the dotted lines 3 3, Fig. 1. Fig. 4 is a sectional detail of one of the end loops and the counterbored rail.
a and I) represent the rails, c the fish-plate, and (1 one of the bolts which passes through a hole in the fish-plate and through a hole in the rail.
The bolt-hole in the rail is counterbored, as best shown in Fig. 4, to receive the end loop of the rail-bond.
The rail-bond comprises, essentially, an intermediate portion e, having at each end a circular loop f. The intermediate portion is flexible or extensible. The railbond is preferably composed of anarrow strip of sheetcopper wound or folded upon. itself to form a laminated bond, and the several layers are bent or formed at the ends to provide circular end loops The intermediate portion of the bond will be of any shape desired. The circular end loopsf are offset relatively to the intermediate portion, as shown in Fig. 2, so as to enter the counterbored bolt-holes in the web of the rails by bending the ends of the intermediate portion at an angle, as shown in Fig. 4, the end loops extending from said angularly-formed ends in planes in parallelism with the intermediate portion. The end loops are made circular, so as to fit the counterbored bolt-holes and provide for the bolt which passes through said bolt-holes. The several layers composing the circular offset end loops are soldered together, while the several layers composing the intermediate portion remain unattached.
The circular end loopsf when placed in the counterbored bolt-holes are held securely therein by solder.
The bolts which pass through the boltholes provide against the removal of the bond, and as the bonds are concealed by the fish-plates their detachment from the rails by malicious persons is obviated.
Having thus described my invention, what I claim as new, and desire to secure byLetters Patent, is
1. A rail-bond comprising an intermediate portion bent and turned rearwardly near its opposite ends and terminating in circular loops, in combination with the meeting ends of two rails having counterbores in which said loops are seated, substantially as described.
2. A laminated rail-bond having its ends bent rearwardly and formed into loops, and rails provided with counterbores in which said loops are seated, substantially as described.
3. A laminated rail-bond having an intermediate portion with its ends bent and turned rearwardly and formed into loops, the faces of which are in a plane parallel with the intermediate portion, substantially as described.
4. A laminated rail-bond having an intermediate portion with its ends bent rear- In testimony whereof I have signed my wardly and formed into loops, the faces of name to this specification in the presence of which are in a plane parallel with the face of two subscribing witnesses.
the intermediate portion, and rails provided WILLIAM GRANT STUART. 5 with counterbores in which said loops are Witnesses:
seated, and means for securing said loops in BLANOHE B. KIMBALL,
said bores, substantially as described. EDWARD H. ROWELL.
