RAILWAY- RAIL JOINT.

sPEOIFICATION forming part of Letters Patent No. 510,268, dated December 5, 1893.

Application filed February 18, 1893. Serial No. 462,906. (No model.)

T0 at. whom it may concern:

Be it known that I, LEONARD W. KENNEDY, a citizen of the United States, residing in Oakland, Alameda county, State of California, have invented an Improvement in Railway- Rail Joints; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to a joint for railway rails, which I call an anchored anvil rail joint.

- It consists in certain details of construction which will be more fully explained by ref erence to the accompanying drawings, in which- Figure l is a view showing the form in which the support is interposed between the webs and flanges of the rails and the rail-heads abut together. Fig. 2 is a view in which the intermediate support is extended up between the heads of the rails. Fig. 3 is a perspective view showing a V-shaped joint and the fastenings. Fig. 4 is a vertical section of the same. Fig. 5 is a perspective view showing diagonal beveled meeting ends of rails and joint and fish-plate fastenings. Fig. 6 shows the tie rod. Fig. 7 shows the rail without bottom flange. Fig. 8 shows the blocks formed with the tie.

Fig. 9 shows a fish-plate and block formed together. Fig. 10 is a side view of Fig. 8.

,Great difficulty is experienced in making suitable joints between the. meeting ends of railway rails. On account of the constant pounding and variation of weight when heavily loaded trains pass over such joints, they are continually rising and falling with reference to each other, and the passage of the wheels over these unequally supported ends causes a constant hammering which soon spreads and batters the rail so that it must be repaired or replaced.

My invention contemplates the interposition of an anvil block or support which extends between the meeting ends of the rails, and serves as a tie and support therefor.

A and B are two rails which meet and require to be supported in line with each other. For this purpose I have shown a block 0 formed with a base D extending transversely from it, and of sufficient size to provide a broad support upon the tie or other surface where it is placed. This block is made of any suitable or desired length in the direction of the line of the rails, and the flanges and webs of the rails may be cut out so as to allow the block'to be introduced beneath the heads E of the rails which project over it at their meeting points, as shown in Figs. 1, 2 and 4; In some cases the blocks for the two rails are rolled with an iron tie, and project upward from it, in-which case the tie binds the rails and prevents spreading. In other cases the blocks are formed with the fish-plates on one side, so that when bolted to the rails, the blocks extend between the ends of the rails, and form the joint.

In Fig. 1, I have shown the supporting anvil of such length,and the flanges and webs of the rails cut away to such an extent, that the heads of the rails abut together above this support.

In Fig. 2 I have shown the support made of greater length and havingan extension 0' of the same shape in transverse section as the heads of the rails, and of sufficiently less length than the base of the support, so that while this extension projects up between the meeting ends of the rails, the base extends in each direction beneath the heads of the rails, the webs and flanges being cut away as before described to admit the support to lie between them. The base flange D extends out transversely in each direction',"as before described, and serves as asufficientsupport for the joint connection.

In Fig. 3 I have shown the rails having the heads out V- shaped and the intermediate head C of the support has corresponding V- shaped channels cut in it to receive the heads of the rails. The webs and flanges of the rails are cutaway, as previously described, to admit the body 0 of the supporting anvil between them.

G G are fish-plates suitably formed to clasp the support 0, and to-extend upon either side of it along the webs of the abutting rails,bein g secured thereto by bolts in the usual manner.

The central portion of the fish-plate, shown in Fig. 3, is curved outwardly and has a recess made in it to fit over the projecting sides of the supporting anvil, while the ends of the fish-plate extend along closely against the opposite sides of the webs of the rails.

In Fig. 2 I have shown the support block made with large transverse extensions which are also sloped down each way from the rails, and are firmly boltedupon the'ties or other supports. The rails abut against these supports, as previously described, and may have their ends either at right angles or formed'in V-shape as shown in Fig. 3, or beveled, with the inclines extending from the one side to the other, the head of the anvil support which projects up between the rails being correspondingly shaped, so that the rails will fit against it,-as shown in Fig. 5.

The rails of each trackmay be tied together by rods which unite the anvils when they stand opposite each other as shown in Fig. 6, and thus prevent spreading.

Iron ties'may'be made with the anvil blocks rolled asapartof the tie, and at the proper distance-apart, as shown at Fig. 8, sothat the rails ofeach" line of the track abut against the anvil blocksand are properly securedby the fish-plates. be rolled with a fish-plate upon one side having ends extendingin each direction so as to be bolted to the abutting rails betweenwhich the block projects, and the fish-plate upon the opposite side is bolted on in the usual manner,

or if the anvil block is made separate and introduced between the rails as previously described, independent fish-plates" may be employed to unite the parts.

A joint constructed in the manner herein described reinforces and strengthens the joints,makes them smooth by dividing the spaces allowed for expansion, and the solid interposed anvil piece receives the principal force of the blow ofthe wheels, thus protecting the ends of the rails, and preventing their brooming, as it is termed. It also eliminates the hinge motion of the present joints, thereby. preventing the blowing of the dry,and the pumping of the soft wet road-bed'from beneath, thus preserving a smooth even track, and reducing the cost of maintenance of roadbed and rolling stock. It anchors each rail so firmly as to segregate the expansion and contraction, and prevents its being communicated from one to another and becoming cumulative. It guarantees exemption from crawlingon grades, or spreading, and the extensions or base supports make it impossible for the rails to turn.

In some cases it may be'desirable to make rails light by rolling them without the bottom flanges. The ends of the rails will thus be united and supported by the anvil joints-and The anvil-blocks may also the intermediate portions by chairs slotted to receive the lower edge of the webwhich is suitably fixed therein.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A railway joint consisting of an anvilsupport for the head adapted to be fitted between the rails in seats formed by cutting away portions of the webs and flanges.

2. In a railway joint, the rails the adjoining ends of whose webs andflanges are cut away, and an anvil-support fitted in said cutaway portions and supporting the heads at their meeting ends.

3. A railway rail joint, consisting of an anvil support having a transverse base supported upon the foundat-iontiesan upwardly extending block fitting between the endsof the webs and flanges which are cut away for the purpose, and beneath the heads of the rails which rest directly thereon, substantially as herein described.

4. A railway rail joint consisting of a block interposed between the flanges and webs of two abutting rails which are cut away to receiveit and beneath the headasaid block having an extended base adapted to be supported upon the foundation ties, and an upwardly projecting head corresponding in shape with the heads of the abutting rails and forming an independent section between the meeting ends of saidrails, substantially as herein described.

5. A railway rail joint consisting of rails having-webs and flanges cut away beneath the headset said rails,ablock interposed between said webs and forming'a support heneath the heads of the rails, said block havupon the foundation ties, fish-plates fitting the opposite sides of the webs of the rails and adapted to claspthe interposed anvil block and bolts whereby said plates are secured to the rail flanges upon each side of said blocks, substantially as herein described.

6. A railway rail joint consisting of anvil blocks rolled'as a part of metallic ties,pro jecting upwardly therefrom and adapted to fit between the adjacent ends of the rails, and fish-plates by which the ends of the rails and the interposed anchored blocks are united, substantially as herein described.

h In witness whereof I have hereunto setmy and.
