T @ZZ whom, t may concern:

Be it known thatfwe, WILLIAM WHARTON, Jr., a resident of Fhila'del-phia, and VICTOR ANGERER, a resident of Ridley Park, Penn- In the accompanyingdrawings, Figure 1 is a plan view of a railway-switch illustrating our invention. Fig. 2 is a sectional plan View of one of the switch-rails. Fig. 3 is an enlarged 2O plan view of a portion of the switch-rail. Fig. 4: is an enlarged sectional plan view of that portion of the rail shown in Fig. 3. Fig. 5 is a transverse section on the line 5 5, Fig. 1. Fig. 6 is a transverse section on the line 6 6, Fig. l. Fig. 7 is a transverse section on the line 7 7, Fig. l; and Fig. 8 is a perspective view of certain detached parts illustrating our invention.

A and A are the rails of the main track, and B and B are the rails of the siding or turn-out.

'The type of switch illustrated is what isV known as a point-switch, the switch-rail C being hinged at J in continuation of the siding-rail B and the switch-rail C being hinged at J in continuation of the main rail A; Each of the said switch-rails has a tapered point at its free end, so that when required the tapered point may be moved up to and lie against the 40 Y inner side of the adjacent fixed rail of the track,

one position of the switch being shown in Fig. 1.

The thin tapering points of point-switches are subjected to excessive lwear, and consequently are worn out much sooner than the other parts of the switch-rails, and when the point is worn out the whole rail must be discarded and be replaced by anew one. We overcome the above objection by making each switch-rail in two pieces. The body-` 50 pieces H H are ordinary rails, while the pointpiecesv D D are f ,preferably made of hard metal, such as manganese steel, and-they are rigidly secured to the body-pieces H and H in the manner described hereinafter. We will describe the invention in connection with the switch-rail C. The body portion of this rail in the present instance is an ordinary T-rail having its head partiallylcut away, as at @,Fig 8, for a certain distancefromone 60 .end to fit a correspondingly-shaped end d,

Fig. 8, of the point portion D', so'that when the two portions are coupled together the joint between the body portion H and the pointed portion D will not extend directly across the head. The shape of this joint may be modied, as desired, the object being to do away with a right-angle transverse joint. The point portion D' is preferably provided with a flange d', extending the full length of the 70 portion D', vas illustrated in the drawings, and

in order to strengthen the joint between the p'oint portion D and the body portion H we extend the under part of the point portion D beyond the joint, so that this extended under part 032 will lie under the head of the T-rail, Which constitutes the body portion H', and be bolted or otherwise firmly secured to the body portion, as shown in Figs. 2, 3, and 4.

E is a reinforcing bar or plate which is se- 8O cured to the point portion D and also to the body portion H and is of suchva length as to materially strengthen the entire switch-rail.

It is preferably increased in thickness at e opposite the joint between the body portion H' 35 and the point portion D.

When the parts are assembled, the web of the T-rail constituting the body portion H is clamped between the extension @Z2 of the point portion and the thickened portion @of the plate E. We have Shown rivets z' attaching the parts together; but it will be understood that other means of fastening may be employed without departing from our invention.

In order to laterally strengthen switches of this character and to simplify their construction, we make the flange'd of the point portion D of such a width that it not only strengthens the point, but we can also secure the tie-bars F directly to the ange d by means of the bolts or pins f, said tie-bars being forked at each end to receive the flanges.

In the drawings we have shown the position of the lateral flange dto be at the lower or bottom part of the point portion D'; but it may be desirable in some instances to raise the position of this fiange, and we therefore do not limit our invention or confine ourselves to the position thereof shown in the drawings.

The point portion D' being easily detached from the body portion H', it can be taken off when worn out and be replaced by a new point portion without the expense of renewing the entire switch-rail.

By making the point portion Dof the switchrail of a very hard metal, such as manganese steel, the thin and relatively delicate part of the same at and near the extreme point will resist wear for a much longer time than usual, While the remainder or body portion H may be made of Bessemer steel or other less expensive material.

rlhe mechanism for throwing the switch can be attached thereto by any ofthe usual methods. We have shown in the drawings a switchrod g, which is coupled to one of the tie-bars through a spring-box G; but other suitable i means of attachment may be used without departing from our invention.

We claim as our invention- 1. The combination in a railway-switch, of a switch-rail made in two sections, and a reinforcing bar or plate secured to the web of the point-section and to the web of the bodysection, substantially as described.

2. The combination in a railway-switch, of the body-section of a switch-rail, a point-section having a prolongation beyond the joint extending longitudinally along the web of the body-section, a reinforcing bar or plate on the opposite side of the body-section and extending beyond the joint along the side ofthe pointsection, and means for securing the several parts together, substantially as described.

3. The combination in a railway-switch, of the body portion of a switch-rail, a point-section having a prolongation extending beyond the joint along the web of the body-section, a reinforcing bar or plate on the opposite side of the body-section and extending beyond the joint along the side of the point-section and increased in thickness at the joint, and means for securing the several parts together, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
