iINSULATED RAIL-JOINT.
SPECIFICATION forming part of Letters Patent No. 784,741, dated March 14, 1905.
Application filed January 9,1904. Serial No. 188,305.
To all whom, 'lit 71u14/ cm1/cern:
Be it known that I, GEORGE L. HALL, a citi- Zen of the United States of America, residing in the borough of Brooklyn, city of New York,
.county of Kings, and State of New York, have jacent rails of a railway and to the insulation of one rail from therail adjacent to it; and its object is to provide an all-metal joint having base-support in which only one of the rail ends need be insulated from the metal parts crossing the joint.
To this end my invention consists of means whereby one of the rail ends is insulated from all parts of the joint which might electrically connect it with lthe other rail end.
l hereinafter describe a rail-joint embodying my invention and then point out the novel features in the claims, having reference to the accompanying drawings, in which similar numerals of reference indicate similar parts throughout the various views, of whichM Figure 1 is a plan View. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a section on the line 3 3 of Fig. 1, and Fig. 4 is a view of a modification. Fig. 5 is a side View of the modification shown in Fig. 4. Fig. 6 is a view similar to Fig. 1, showing a modification. Fig. 7 is an enlarged detail view of a modification, and Fig. 8 is an enlarged detail view of the washer 14' shown in Fig. 6.
1 represents a rail end electrically insulated from those parts of the joint that might otherwise electrically communicate with the other or adjacent rail end, 2.
3, 4, and 5 indicate members of a shoe-angle on one or preferably the out side of the joint. 2O is an angle-iron or metal band on the other or in side of the joint. The chair or shoe is insulated from the rail end 1 by insulating material 6, such as fiber, and the angle-iron or metal band 2O is insulated from the rail end 1 by insulating material 7.
8 and 9 are filling-pieces to compensate, re-
spectively, for the insulating parts 6 and 7. Of course it will be understood that l do not limit myself to this method of compensating' for the space occupied by the insulating material 6 and 7; but the method shown is a convenient and cheap manner -of accomplishing the desired result. For instance, the shoe or chair and the angle-iron or metal band might be made of thicker material at one end than at the other.
10 and 11 are bolts for securing the parts of the joint together. The bolts 10, passing through the rail end 1, are insulated from the chair or shoe and the angle-iron or metal band by the well-known insulatiiig-washers 12 and bushing 13.
14 indicates washers for protecting the insulating-washers 12.
^ lt is often desirable to use instead of squareheaded bolts 10 and 11 (shown in Figs. 1 to 3) bolts having an oval-shaped neck like those shown at 10' and 11' in Figs. 4 and 6. The object of using bolts having oval-shaped necks-is to render it unnecessary to use an additional wrench to prevent the bolt turning as the nut is screwed up, and of course it will be understood that a stationary part must be provided with which the oval-shaped neck of the bolt may mesh. 1 therefore provide a washer 14', as shown in Fig. 6, including at least two of the bolts, said washer 14' being provided with ovalshaped holes for the necks of the bolts, as shown in Fig. 7. Of course I do not limit myself to an oval-shaped neck, as it will be readily understood that any other shape than round would answer the same purpose. lt will also be understood that I do not limit myself .to a joint having one chair in combination with an opposite band or angle-iron,as the wellknown construction of two opposite chairs or a chair with two opposite bolt-plates might be used. In Figs. 4 and 5 I have shown such a modification of my invention, in which 3', 4', and 5' indicate the members of the opposing chairs and bolt-plates. I sometimes provide additional strength to such a joint by means of lugs 21, depending from thel chairs, in combination with bolts Q2.
2. In an insulated rail-joint the combination of ametal band or fish-plate crossing the joint withy a plurality of bolts passing through said band and one of the rail ends, saidbolts being provided with necks other than round, and a washer adapted to include at least two of said bolts and provided with holes adapted to mesh with the necks of said bolts.
In witness whereof I have hereunto set my hand this 7 th day of January, 1904.
GEO. L. HALL.
In presence of- ALoYsIUs E. TENHAGEN, J. F. BOUDREAU.
