DUPLEX RAILWAY WEAR-PLATE.

SPECIFICATION forming part of Letters Patent No. 623,420, dated April 18, 1899.

Application filed October 18, 1898. Serial No. 693,369. (No model.)

To (bZZ whom it may concern:

Be it known that I, CALVIN DAVID PAXSON, a citizen of the United States, residing at Limaville, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Duplex Railway Wear- Plates, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to railway wearplates which are inserted beneath the rails upon the usual wooden ties and which generally are provided upon their under surfaces with projections or means of anchorage to the tie and upon their upper surfaces with a shoulder or shoulders against which the edge or edges of the rail are intended to bear; and the object of my invention is to provide a plate which shall serve to receive the rail firmly upon its upper surface and not only support the same against the outward lateral thrust of traffic, as is the object of every shouldered wear-plate, but which shall also firmly hold the rail against either inward or upward movement, my wear-plate being particularly designed to closely clasp the rail without the necessity of sliding the rail thereinto, which is operatively impractical, a further object of my invention being to provide a novel form of anchorage peculiarly adapted to my newly-invented form of plate and capable of use therewith when desired.

\Vith these ends in view my invention consists of a wear-plate formed of two separate parts having their inner or mutually-abutting edges so formed that the plates interlock in a manner to prevent independent movement thereof longitudinally of the plate or of the tiethat is to say, transversely of the rail and otherwise constructed,pre ferably as hereinafter fully described.

In the accompanying drawings, Figure 1 represents a plan view of my duplex or combination plate. Fig. 2 is an edge view thereof with a portion of the rail shown thereon in transverse section. Fig. 3 is a plan view of a modified form of one of the plate members. Fig. l is an edge view thereof from the inner side or that which abuts against the corresponding side of the opposite member, and

Fig. 5 is a side view of the plate seen from the outer portion or edge thereof.

The wear-plate consists of two members A, both of which, as shown in Fig. 1, are preferably of precisely the same shape, so that they are interchangeable and any two members constructed according to my invention will work together. The form of each plate is essentially that of a rectangle elongated longitudinally or in a direction transverse to the rail and with the inner edge thereof cut out on three diagonal lines a Z) c to comprise a zigzag edge, which ranges from one end of the plate diagonally inwardly to a point 0, thence diagonally outwardly to a point I), and thence diagonally inwardly to the opposite end of the plate, and upon one end of each of the said members A A is formed a shoulder B, which ranges transversely across the plate and projects from theend thereof a predetermined distance toward the opposite end, preferably sufficient to in actual practice bear against the tongue of the rail 0 and to receive the base thereof beneath the same, said shoulder following the zigzag edge of the plate along the line a and portion of the line Z). Y Extending through each shoulder is a spike-hole D, and I also prefer to form a spikehole D in the opposite end of each member of the plate.

lVhen the two members of the plates are placed together, as shown in Figs. 1 and 2, with the shoulder B of the member A on the outer side of the rail and the shoulder B of the member A on the inner side of the rail, it will be seen, first, that they will securely clasp the rail between them, and, second, that the zigzag edges of the plate members will cause them to interlock and be independently immovable laterally.

In the operation of the device each of the plate members is inserted beneath the base of the rail a slight distance apart, with the shoulders 13 thereof clasping the rail-base and bearing against the rail-tongue, and the members are then moved together longitudinally of the rail until they interlock, whereupon spikes are driven through the spike-holes D and also preferably through the spike-holes D. This permits that each of the shoulders may clasp the rail-base without the necessity of sliding the end of the rail between them, as would be the case were they formed upon one plate, or of making one of the said shoulders movable or separate from the plate,which would be another possible alternative, and by this construction of my device the duplex plate is readily mounted upon the tie, beneath the rail, to firmly clasp the same and has, as stated, the characteristic of an integral plate as respects lateral movement. It will be noted that the outward thrust against the shoulder B of the member A will be distributed between the two members by the bearing of the faces a and 0 against the opposite faces of the member A, and in this connection it will be noted that as an outward thrust upon the rail is received at the top thereof from the car wheel there is an accompanying tendency of the rail to rise upon the inside, and this will be checked by the opposite shoulder B of the member A. The spikes which secure the plate and the rail serve to prevent separation of the members longitudinally of the rail, which will also be accomplished by any suitable form of anchorage which may be employed upon the under surface of the plate. In the manufacture of the plates they may be formed in any desired manner, and I do not desire to confine myself in this regard.

I have shown in Figs. 3, 4, and 5 a modified form of plate member which is originallycon- 'structed in the elongated rectangular form and out along the line cl to the point 0, so that to form the zigzag edge of the plate the remaining portions 66 ,21 and a may be struck downwardly to form flanges or projections, which will project vertically from each of the edges a, b, and c, and will thus have cutting edges or points e, which will enter the wood of the tie, and by reason of the diagonal ranging of these flanges or projections they will.

serve to prevent both the lateral and longitudinal movement of the plate and, running across the fibers of the tie, will not tend to split or separate the same unduly, but will rather cut into them. I do not claim, broadly, a diagonal flange as an anchorage upon a wearplate,however, but simply this zigzag arrangement thereof and the combination thereof with the plate member.

I conceive that my invention may be employed even without using the exact form of shoulder which I have herein illustrated and described, though I consider its chief merit and advantage to exist in connection therewith.

Having fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A railway wear-plate, comprising two plate members mutually abutting upon their longitudinal inner faces or at an angle transversely to the rail, and provided upon said faces with zigzag edges whereby when said plate members are moved together longitudi nally of the rail upon the same plane, said edges will interlock to prevent independent movementof said plate members transversely to the rail.

2. A railway wear-plate, comprising two plate members, one or more of which is provided with a shoulder adapted to engage the rail to receive the thrust thereof, and the inner and longitudinal abutting faces of the two plate members being provided with zigzag edges whereby they interlock against independent movement transversely of the rail, and wherebyany movement of said rail transmitted to the shoulder of one plate member will be supported by the resistance of the other interlocking member.

3. In a railway wear-plate, a member or plate formed from a rectangular blank having one side out laterally and struck downwardly to form azigzag edge a, b, c, the struckdown portions projecting at three difierent parts of said edge diagonally with respect to the plate and having cutting edges or points 6, adapted to enter the wood of the tie.

4. A railway wear-plate, comprising two plate members of equal thickness, and each formed alike or interchangeable with one of its longitudinal edges or that which ranges transversely to or across the rail formed with a zigzag edge adapted to interlock with the corresponding edge of the opposite plate member whereby said members are independently immovable transversely of said rail.

5. A railway wear-plate, comprising two members adapted to interlock, and each provided with a shoulder to clasp the rail, one or more of the said members being formed from a rectangular blank and having one edge thereof cut out and struck downwardly to form diagonal faces a, b and c, with integral flanges or projections extending downwardly from each of said faces.

6. In a railway wear-plate, a member or plate formed from a rectangular blank having one side thereof cut laterally and struck down to form zigzag edges Z), and c, and corresponding flanges lfi, and c ranging at opposite angles diagonally to the plate, and by such cutting formed with sharp points or cutting edges 6; and the end of the plate opposite the flange 0 being struck down diagonally of the corner thereof to form a similar flange a ranging oppositely to the flange W.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 10th day of October, 1898.

CALVIN DAVID PAXSON.
