1.1 which,

To all whom it may concern:

Be it known that I, GEORGE WHITE- MAN, a citizen of the United States, residing in Philadelphia, Pennsylvenim'heve invented certain Improvements inR-nilrond- Switches, of which the following is a specificetion. 1

My invention relates to railroad. switches; and the object of my inventioispro vide an improved structure w reh l em. enabled to thicken. the end of the point switch and to provide, for the recess in the head of the stock rail accommodating such thickened end of the point switch, a reiniorce therefor that will amply support said stock rail and protect the some against any damage or failure by reason of the extra recessing demanded by the thickened end of the point switch. The supplemental member or rail section reinforcing the stock rail may be raised to conform to the (toning of the car wheel tread.

These and other features of my invention ,will be more fully described hereinafter,

reference being had to the accompanying drawings, in which:

Figure l, is a plan view of a. switch constructed in accordance with my invention; Fig. 2, is a sectional view on the line 2- 2, Fig. 1; Fig. 3, is a similar sectional View illustrating a detail of my invention; Fig.

i, is a sectional view, similar to Fig. 1, illustrating a modified construction within the scope of my invention, and Fig. 5, is a sectional view similar to Fig. 4, illustrating it further detail of my invention.

Railroad practice at the present time includes the use of heavy section rails. In the use of such rails, however, the ordinary practice of planing the point switches to one-eighth inch on the point is not an economical proposition and conditions demand that the end of the point switch be much thicker. To accommodate such a switch point, however, it is necessary that the stock rail he recessed to it much greater extent than the usual practice or conditions heretoiorc have demanded, and in such extra reccssing oi the rail, which would llii-Vfi it material tendency to weaken the some, ample protection against all danger of breakage -must be provided.

in fact, there has been no general practice of rccessing the mil owing to the weakening eiicctupon the section for fear of the rail breaking under trafiic. In order to compensate. for the poo" tion cut from the stock rail in recessing the same, I. propose to reinforce the stock rail, thereby giving additional strength at each point and also providing at greater wearing area for the trend of a wheel as it leaves the incline of the switch point Ii. desired, t is reinforcing section may he set level with the top of the stock mill, or it may he ole voted to an extent sufficient to conform to the coiling of the wheel trend.

In the drawings, 1, 1 represent the stock rails on opposite sides of a switch, and 2, 2 represent the thic zoned switch points; the rails he g ycCQSSQd at d 3 on the inner sidw of the heads, as clearly illustrated in the drawings, to receive the ends of said switch points. The reccssing at its deepest point it'will he noticed, extends nearly to the cen ter of the rail head, and in general may er;- tend to the face of the central web supportthe heed of the rail.

in order to compensate for this recessing' and strengthen and support the stock mile, 1 provide reinforcing inc-ens outside the lotter, which reinforcing means may he in the form oi short mil sections 4., i, having preferably a section equni to the ordinary stock mil; with it suitable hlocl; ntergit .d

between the wehs of the stock rails and the I F reinforcing rail sections, which members ere then secured together by the use of loo-its 3 and nuts i, or similar suitable securing means passing; through said. webs and the filling blocks.

in lieu of the use of'shor rail sections, the

length of which moreover only he iinyti desired to fully protect the switch, provide a block 5 of suitable cross section which will have a suitable heed nortion and a lateral filler portion 5 to engage the web oi? the stock rail and substantially fill the space between the head. and hose of tile same; such block being? held. in place and to the stock rails by bolts 6 and nuts 7*. The ends of the rail sections 5, or of the special blocks 5? may he beveled, as indicated at 9. The reinforcing rail sections 5, or the re inforcing hi ck members 5 may have their upper surface on. the plan per surface of the head of the 5 shown in Figs; 52 and 4t, or th may he raised with relation to said stock mils so cs to provide with 'iihe hitter n surface coir forming to the coming of :1 car wheel. trend, as shown in gigs. 3 end 5. 1

By employing recessed stock rails such Esitenteil dolly Moll-lies.

its

as I tnropose, with a thickened switch point, I

the splitting of the latter at the point will be n'cvented even when said point is not held tightly to the stock rail. Under present practice, it is quite difiicult to hold the pointclose to the stock rail owing to the size of the sections and theirincreased stiflness which greatly limits their ability to bend in elfccting the necessary lateral displacement of: the same.
