JAMES C. MOCK, 013 DETROIT, MICHIGAN;

RAIL-JOINT.

To all whom it may concern 7 Be it known that I, JAMES 0. Moon, a citizen of the United States, and residing at Detroit, in the'county of Wayne and State of Michigan, have invented a new and Improved Rail-Joint, of which the following is a specification.

This invention relates to means for connecting adjacent endsof railway railsin such a manner that while these ends will be held in substantially perfect alinement, they will be insulated fromeach other.

This invention consists, in combination with the rail-ends and sheets of insulating material surrounding these ends, of fishplates fitting between the heads and bases of the rail-ends and having central portions extending below said bases, and adjustable wedges'adapted to be drawn into the spaces between the lower sides of the bases of said rail-ends and the extensions on the fishplates to secure the parts together.

In the accompanying drawing, Figure 1 is an elevation of a rail-j oint in position. Fig. 2 is a view showing a rail and one fish-plate in section on the line 22 of Fig. 1, and another fish-plate inend elevation. Fig. 3 is anend elevation of a fish-plate. Fig. 4. is a side elevation of a wedge. Fig. 5 is a section on the line 5-5 of Fig. 1.

Similar reference characters refer to like parts throughout the several views.

The rails 1 and 2 shown are of usual design and are separated by a sheet 3 of hard insulating material such as rubber, guttapercha, vulcanite, fiber board or any other desirable substitute therefor. .Other sheets 4 and 5 of hard insulating material extend along below the rail heads 6, down alongside of the webs 7, out above the bases 8 and around the edges thereof and inwardly below said bases. The portion extending be-- low the bases need not be the full length of the main portions of the fish-plates as the lower portions of these members are of less length.

The two fish-plates 9 extend along between the heads and bases of the rail-ends, being beveled so that where the fish-plates are drawn toward each other by means of the bolts 10, the union between them and the rail-ends will be very rigid. Sleeves 12 of insulating material are shown on the bolts while other sleeves 13 within the holes in the fish-plates add additional security. Squares 14: of insulating material are slipped onto Specification of Letters Patent.

Application filed January 26, 1916. Serial No. 74,299.

through the lugs 24 formed on the wedges 25 that lie between the extensions 18 and the bases of the rails. When drawn outwardly these wedges force the bases of the adjacent ends of the rails up against the yertical portions of the fish-plates and thus insure a very rigid joint. These bolts 23 and wedges 25 are positioned before the fishplates are applied to the rails, and after the fish-plates arev secured in position, the wedges are drawn outwardly to lock the parts together and to give positive support to the adjacent ends of the rails. Bythe use of these wedges, the slight movements between rail-ends inherent in all rail-chairs is avoided. The extensions 18 and wedges 25 need not be as long as the main portions of the fish-plates and therefore do not necessitate a great deal of cutting of the crossties. One bolt 23 may be found sufiicient for each wedge 25.

The proportions and details of the parts may all be changed to conform to varying requirements Without departing from the spirit of my invention.

I claim 1. In a rail joint, the combination of the abutting rail ends and the fish-plates, projections on the fish-plates having inclined faces extending under the rails, a wedge interposed between and bearing against each of said faces and the bottom of the ends of said rails, and .a bolt projecting from each wedge through the projection on the fish-' passing through the fish-plates and the rail ends, projections on the fish-plateshaving projection on the fish-plate which said wedge engages,

74:. 'A rail jointcomprising fish-plates and the interposed rail ends, projections on the fish-plates having inclined faces extending under the rails, a transverse wedge interposed between and bearing against each of said faces and the bottom of the ends of said rails, and means to force the wedges away from each other for the purpose specified.

V -5. Arail joint comprising fish plates and interposed rail pends, bolts passing through the fish plates and the rail ends, projections on .the fish plates having inwardly and downwardly inclined faces extending under the rails, wedges interposed between the inclined faces and bottom of the rails, and means toforce the wedges away from each other, substantially as described.

6. A rail joint comprising fish plates and interposed rail ends, bolts passing through the fish plates and the interposed rail ends, projections on the fish plates having in wardly and downwardly inclined faces extending under the rails, wedges interposed between the rails and the, projections on the fish plates, and means to force said wedges away from each other, substantially as described.

- tions onthe fish plate it engages substan wardly and inwardly inclined faces extending under the rails, wedges interposed between the bottoms of the rails and the projectionsvon the fish plates, and bolts projecting from one wedge through the projectially as described.

8. In arail joint, the combination of: the

abutting rail ends and the fish-plates, insulating materialseparating the rail ends from each other and the fish-plates, projections on the fish-plates having inclined faces extending under the rails, a wedge interposed between and bearing against each of said faces and the bottom of the ends of said rails, and a bolt projecting from each wedge through the projection on the fish-plate with which it engages.

9. In a rail joint, the combination of the abutting rail ends and the fish-plates fitting the same, sheets of insulating material between the rail ends and the fish-plates, bolts passing through the fish-plates-and the rail ends, projections on the fish-plates having inclined faces extending under the rails, a

wedge interposed between and bearing against each of said faces and the bottom of the ends ofthe rails, anda bolt projecting from each wedge through the projection on the fish-plate with which it engages.

10. In a rail joint, the combination of the abutting rail ends and the fislrplates, insulating material between the abutting rail ends and between these rail ends and the fish-plates, bolts passing through the fishplates and the rail ends, projections on the fish-plates having inclined faces extending under the rails, a wedge interposed between and bearing against each of said faces and the bottom of the ends of said rails, and bolts projecting from each wedge through the wedge and projection on the fish-plate which said wedge engages.

11. A rail joint comprising fislrplates and the interposed rail ends, sheets of insulating material between the fish-plates and rail ends, projections on the fish-plates having inclined faces extending under the rails, a transverse wedge interposed between and bearing against each of said faces and the bottom of the ends of said rails, and means to force the wedges away from each other for the purpose specified.

In testimony whereof I sign this specification.
