To an whom; it 777/021] concern/.-

Be it known that I, WILLIAM W. ALLEN, a

citizen of the United States, residing at Sloatsburg, in the county of Rockland, in the State of New York, have invented certain new and useful Improvements in Railway- Switches, of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof,

This invention relates to the slide-plates upon which the switch-tongue moves and:

u on which the rail is mounted. Such slide ates are commonly provided with risers,;.

which lift the switchoint substantially-t the level ofthe railange, so that it t-rnay move partly over the flan e and liesnugly against the rail-head. Sue risers are sometimes formed by striking up. the lates from i the'underside,but this reduces t e width'of the bearing of the :pla'tesupon-the ties and is therefore objectionabla and,moreover, the

shoulder formed at the end of such riser is not a squareshoulde'r, furnish a proper stop for -the rail-flange. In

'- "objections above enumerated and shall,

moreover, furnish adequate stops for the hereinafter.with reference to the accompaand rail-brace in elevation and the rai and therefore does not some cases also such risers have been formed separately and securedto the plates by rivets and'otherwise; but the securing meansfre quently-give 'way in use, and trouble is there: occasioned. v j It is the object of this invention to rovide a slide-plate which shall be free from a l of the rail-flanges on opposite sides thereof.

In accordance with the invention the improved slide-plate is formed, preferably, by rolling with a continuous flat under surface and an integral riser on its upper surface. The riser is then cut out toforrn' a seat for the rail-flange, and it may also be cut out .to form a seat for the railbrace,the shouldersthus formed being square, and therefore constituting adequate stops for the rail and for q the rail-brace, so that lateral movement of the railupon the plate is practically impossible.

The invention will be more fully explained nying drawings in which-it is illustrated, and in which" a Figure 1 is a view showing the sliderlplateand switch-tongue in section. Fig. 2 is a plan view of the slide-plate. Fig. 3 is a view in 1 As shown in the drawings, the slide-plate a is a substantial plate of metal having a continuous flatunder surface I), as clearly shown in Fig. 3, and having on its upper surface an integral-riser c. I v most conveniently formed by rolling a plate of suitable dimensions, and in this case the riser extends from end to end of the platebody a, It is necessar that the upper surface of the riser shall" e, approximately on rail-flange r at itsedge. Conse uently the riser after being formed, as state is out out down to the upper surface of the pla-tebody a to form'a seat'for the rail, square shoulders being therebyformed at d and e as stops to co operate with the Pail-flange. and hold the rail late and, are

The rail-brace is supports the rail, as usual, and is seated, as at f 9, upon the plate-body. I claini as my inventionf v 1. A slide-plate for railway-switches having a continuous, flat under surface and upon its upper surface an integral riser, such riser being cut away to the upper surface of the plate-body to form a seat for the rail, with ing also cut away to-the up plate-body to form a seat or the railbrace.

2. A slide-plate for railway-switches having upon-its uppersurface an integral riser,

facefof the platc bodv to form a seat for the rail with square shoulders at each side thereof and bearing directly against the rail.

5. The combination with a rail, a movable switch-tongue and a rail-brace, of a slide-plate having an integral riser to support the switch-tongue, such riser bein cut away to the upper surface of the plateody to form a seat for the rail with a square shoulder at each side thereof and being-also cut away to the upper surface of plate-body to form a seat for the rail-braceI This specification signed and witnessed
