ORA M. DEEMER, OF GILMORE, NEBRASKA, ASSIGNOR TO THE CONTINUOUS RAIL JOINT COMPANY OF AMERICA, A CORPORATION OF NEW JERSEY.

RAIL-JOINT.

SPECIFICATION forming part of Letters Patent No. 782,645, dated vFebruary 14, 1905.

Application filed April 19, 1902. Serial No. 103,769.

To all whom, if may concern,.-

Beit known that I, ORA M.. DEMER, a citiy zen of the United States, residing at Gilmore,

Sarpy county,Nebraska, have invented certain new and useful Improvements in Rail-Joints, of which the following is a specification.

Myinvention relates to rail-joints, and more particularly to that class of rail-joints wherein the rails are electrically insulated one from the other. A

The object of my invention is to provide a rail-joint that will be perfectly insulated and that will be durable and easily set up.

To these ends my invention consists of the construction hereinafter described, and more fully set forth in the claims.

In the accompanying drawings, Figure 1 is a side elevation of the rail-joint. Fig. Q'is a longitudinal section. Fig. 3 is a vertical sec tion.

A and B are the adjoining ends of the rails connected by the fish-plates C and D, these {ish-plates having their opposite ends de pressed on the inner side for one-half their length for the reception of the insulatingstrips E and E, which cover the entire inner surface of each fish-plate for one-half its length. This strip may be of any suitable insulating material. An insulating-block F, of the same material, is fitted between the abutting ends of the rails A and B. When the joint is assembled, the depressed portions of the fish-plates with the insulating-strip contained in said depression are on opposite sides of the joint and on opposite sides of the rails.

Theiish-plates C and D are provided with the usual bolt-holes a and b. In one end of the plate the holes c are elongated for receiv` ing the bolt and holding the same from turning. In the other or depressed end of the {ish-plate the holes are circular and are sufficiently large to allow the insulating-sleeve G to be placed around the bolt. An insulating-washer c is placed between the iron washerA d and the fish-plate, thus thoroughly insulating the bolt from the plate. A separate sleeve G and washer c may be used for insulating the bolt, or they may be made' in one piece, as

shown in Fig. 3. This construction completely insulates the rails, the fish-plates C be- .ing separated from the rail B by the insulating-strip E. The ends of the rails are separated by the insulating-block F, and the fishplate D is separated from the rail A by the insulating-strip'E, and the bolts are separated from the fish-plates by insulating-sleeves G and washers c, as hereinbefore described.

The fish-plates are made exactly alike and both of them will lit on either side of the rails, rendering. it impossible to set the joint up wrong. One side ofeach rail comes in direct contact with and is supported by one of the iish-plates, the under side of the head of the rail and the top of the base-fiange ofthe same bearing directly against the top of the fishplate and the bottom thereof, respectively, which prevents all slipping and cutting of the insulation and makes a rm and durable joint which is not liable to break or become-distorted.

Having thus described my invention, what I desire to claim is l. In a rail-joint, the combinationwith the rails, of the fish-plates having depressions in one 'end thereof, insulating material adapted to fit into said depressions, insulating means for the ends of said rails, connecting-bolts and means for insulating the same, substantially as described.

2. In a rail-joint, the combination with the rails, of the lishplates having depressions formed in one end thereofl and insulating-strips adapted to lit into said depressions, enlarged bolt-holes in said fish-plates, adapted to receive insulating-sleeves for the bolts, substantially as described.

3. In a rail-joint, the combination with the rails, of fish-plates on either side thereof and connecting means for said fish-plates, each of said rails being in contact with one of said sh-plates and insulated from the other of the said fish-plates, substantially as described.

4. In a rail-joint, the combination with the rails, lof the fish-plates on either side thereof and connecting means for said fish-plates, one

of said fish-plates being insulated from oneA side ot' one rail and the second of said iishplates being insulated from the opposite side of the second rail, substantially as described.

5. An insulated'rail-joint havingl opposite splice-bars, each bar having its inner face r'ecessed for one half its length, and insulating material seated in the recesses, substantially as described.

6. A splice-bar having an inner recess eX- tending for one haltl its length and arranged to receive a layer of insulating material, substantially as described.

7 An insulated rail-joint having splicebars, one half only of each splice-bar beinginsulated, substantially as described.

8. An insulated rail-joint having a splicebar, one half of which is insulated, the remaining half bearing directly against the head of the rail, substantially as described.

9. An insulated rail-joint having one splicebar insulated on one side only ofthe rail-joint, and the other bar insulated'on the other side only of said joint, the remaining haltl ot' said bars being in metallic contact with the rails, substantially as described.

10. Inarailwayrail-joint, fish-plates adapted to embrace the rails, said plates having countersunk or recessed portions, and insulating material between the rails and such portions of the plates.

11. In arailway rail-joint, fish-plates adapted to embrace the rails, said plates having countersunk portions, and insulating-shields arranged in said countersunk portions, the thickness of the shields being substantially the same as the depth of the countersunk portions of the plates.

12.` In a railway rail-joint, fish-plates adapted to embrace the rails, said plates having recessed portions, such portion of one plate being non-coincident with the corresponding portion of the complementary plate, and iny sulator-shields arranged between the recessed 15. An insulated rail-joint comprising twoA opposing shoe-angles, means for insulating one of the rail ends from one of the shoeangles and the other of the rail ends from the other ot' the shoe-angles, and means for holding the rail ends in proper alinement.
