other so c'alled special track; structures, "particularlylthose in which frogs areemployd. a

' Heretofore it "has become common .practice among rail'roadst'o cant rails inwardly toward the center of 'the track. 'Such' canting ofzth'e rails is generally accomplishedby the use of inclinedltie platesfi 'It is believed that the cantingbf -rails on an inclination approximating the coning'of the V wheelsinsu'resj central loading of theirail head,

One form of frog embodying features of my invention' is illustrated in Fig. III, and is there shown .to be of the rigid type. In'this example the central region. .of the frog ;designated,; at a is in all respects similar to frogs nowginj general use. Throughout the region a the tread surfaces I6 are flat or substantially so, as shown in VVILand-the base surfaces I! are likewise flat, while the web elements I 8 are vertical-ly 'disposed In referring to flat surfacesfihereih l usethe. word fiat' in a relative sense a id mead-toll parallel with the top plane of the ties in contrast to surfaces which are definitely 'hiclined with respect to the top plane-of the ties.

The point of the frog l is designated illithe I heel rails-atll, 22,:and the-Ming railsEM9223,

, r In order to preserve thexgage (theoretical lines extending wthroug'h the point as at the gage sides 'of the heads justbelowtherunning surface) -.as continuous zstraight rlin'es,1?the twist at the regions bis: accomplished, .as-.illus-.-:'

trated in Fig, V, by. displacing the head, weband base about the 7 axis Jr 'o'r an axissubstantially coincident with the gage line at the rail head;

This displacement of the rails does not. affect the gage lines, andproduces rail-sectionsiatbpposite sides of the regionottwisthaving plane bases inclined at 'anacuteangle z-witheach other.- Moreover, by; twisting the rails about-the axis 1:, the vertical distanceo'f the lowest points of the hat and inclined bases" above the ties.

is substantially the same as indicated in Fig; V.

Accordingly, standard tieplates haying flat sur-f faces. maybe used to' support the ':rails at one 7 tie plates may beused at the other side. At the regions ofthe extremities of the.;frog

side of the region of twist and standard inclined designated at c in Fig. III, 'thediverging 'rail arms are of uniform section with itli'eir tread 'surfaces Ilia and base surfaces Ila inclined-downward'totype.

It will be noted that the springior 'movableiwii g rail 3! has, a flat base surface, throughoutjthe throat oithe frog andthatit therefore bears uni formly upon the base plate 32. J a

With both types of frogs represented in the drawings, the extremities are canted'in-suchman ner as toproduce perfect alignment at the-rail *fis tfittlfi ag.

- to .itsstockirail 9; by reason of the fact: thatthe joints between the point and wing rails of the frog and the abutting rails 2, 3, 4, 5, of the tumout. I I

It isto be noted that all of the rigid rails of the turnout including those specifically designated at 2, 3, 4, 5, 8, 9, l0 and II are canted toward the track center lines. In order to insure ithe properoperation of the movable switch railsgi, 1, these rails are specially designed as shown in Figs. II and VI.

;The switch rails 6, I arecanted at their heel ends through the regions designated at d. Throughout the regions e the switch rails 6, I are twisted, without displacement of the gage lines;

l throughout there'gions j which include the ysdtchpoints, the switch rails have flat bases and tread surfaces and vertically disposed; web elements.- At the switchpoints the relation of the switch rails to the stock rails is as represented in Figs. VIII and IX. In 'Fig. VIII the switch rai1 6 is closed with respect 1150 the stock raili8. The' stock rail 8 canted and :restsv upon the inclined-tseat 33,of;thefgagefplatej; .Tliestock T311115. held: rigidly in place" by an 'adjustable'rail brace ;31 .of.-zconventiona1 type. on the other handthe switchrailfi is vertically disposedwith its fiat. base {35 resting upon the horizontal. top surface ofthe-gage plate... As shownzin Fig. IX, :when the switch rail Iv is opened with respect flat baseof the, switch rail and the .top surface 3610f the gage Vplat'e'34 are disposed-in horizontal planes, there is uniformsbearing between theseielements. .Hence opening and closing of ,the switchbaflbe'effected smoothly and without unevenly. 2

From the above description it'will be apparent that the;incorporation in a railwaynturnout or thezlike 10f .frogs and switch rails twisted in the manner describedsolvesthe problem of cantin rails throughout such special track structures, without -.displacing: the gagelines; or disturbin the alignment of 'abuttingjrails at the joints, or afiecting'the uniform: bearing of,,.movable elements of theistructurefon the underlying plates. while I havereferred*to.certain specific embodiments ofimy :invention, which :have been de-, scribed in v sornedetail, it will; of 'j'cours'e, besa'p parent that many changes may I be, made in the particular fapparatus described withoutv departing fromthes'pirit of my inventionsas defined in the annexed claims. 2: 1
