Application fileu luly 9, 1925. seriai No. 42,540.

To all whom it may concern:

Be it known that I, Gnoucn "W. MnLLER,

citizen of the- United States, residing at Vvashington, District of Columbia, haveinvented certain new and useful Improve- ;ments in Railway-Rail "Construction, of which the following is aspecific ationh This invention relates to railway rail con struction, and hasfor one of its objects to provide a rail formed of a plurality of parts ing stock, and also capable of being transposed with the same end in view. By this latter arrangement a rail is produced con-- taining four wearing surfaces. 7

With theseand'otherobjects in view the invention consists-incertain novel features of construction as hereinafter shown and described and then specificallyfpointed out in-the claims,-and in the drawings illustrative of the preferred embodiment. of the invention:

Figure 1 is-aside elevation of the confronting portions of a pair of rails con structed in accordance with the invention.

Figure 2 is a plan-view of a portion of the parts shown in Figure 1.

Figure 3 is a transverse section on the line 3-3 of'Figure'l, looking in the direction of the arrow. r

Figures 4, 5 and 6 are views similar to 'Figure v3, illustrating modificationsin the construction.

The improved rail is preferably formed of steel with a lower or base portion in cluding a tie flange 10 and web portions '11, the latter having a slightly beveled upper terziinal 12,- with the upper portion hardene The wearing portion'of the rail comprises a head 13 and web" 14, the headportion having av longitudinal channel '15 to receive the r tapered head 12 of the web 11, as shown. In the form of the rail illustrated in Figures 1, 2 and 3, head portions- 13 are" shown at each edge of the web 14, and each with a longitudinal channel 15, one head portion bearing uponthe upper face of the tie flange 10, as shown in Figure 3. The

rail portion thusconstructed may/be -reversed to bring either headportion uppermost, and thus present -either head for engagement by the rolling stock.

posed. from one side to the otherof the track,- thus being capable of presenting four separate wearing faces, as the main wear upon the rails is. upon the confronting portions of the heads, and by transposing the head portions, or changing-from one side of the track to the other, each faceof each of the'head portions may be presented for engagement by the rolling stock, and thus materially increase the life and durability of the rails, thereby insuring a materialsaving in freight and handling charges.

At the lower edge of each of the head portions 13 at. each side, a smalllongitudinal outstanding bead 16 is formed.

In'the form of the structure shownin Figures 1, 2, 3,4 and 5, a. clamp plate 17 is applied to the rails opposite each joint,

each plate having a channel at the upper edge to bear overthe adjacent bead16, .and

The two head portions may also be ,trans- 1 bearing at theilower edge upon the upper face of the flange 10. ,7

The web portion 11 is reduced, intermediate the edges wherebyslight shoulders 18 are formed, and each. side of the webs 14 is formed with a longitudinally directed.

bead 16, one of the beads 16 of the head 13, which for the time being is presented downwardly, and adapted to bear upon the. adjacent stop shoulder :as shown in Figures 3 and. 6, and thus materially assist in supporting the head bearing portion of the rail. j r p In the structure shown in Figure 3 an additional clamp plate 20 is. employed with a channel to bear over the adjacent bead 16, and tapered at'the lower edge and engaging thereby in the channel 15 of the head. portion 18 which forthe time being is presented downwardly.

In Figures 4 and 5 the web 14 is shown formed without the'second head portion 13,

resting on the upper face of the tie flange.

In Figure 4 a single clamp plate 17 is emwith" the free edge laterally extended and ploycl, while in Figure 5 an additional clamp plate 23 is providerhthe latter having a longitudinal channel to receive the adja' cent bead 16.

A clamp bolt 21 of the usual construction operates through the clamp plates 17, 20 and 22), and through the webs 11 and l t, and binds the parts firmly together.

Each of the tie flanges it) rests upon a block of wood, or any other suitable ma: terial, while the latter is located on a con crete foundation or support, imlicated couventionally at 25.

The tie flanges 10 are secured to the blocks E24- and the concrete foundation members 25 by clamp members 26 and clamp bolts 27.

The wood blocks 2st serve as cushion elements to receive the concussions, and preventthem from being conducted to the roll ing stock.

The web 14- is formed with a longitudinally directed recess or cavity opposite the reduced portion of the web 11, and disposed within the cavity is a strip of relatively soft wood indicated at 28, the strip extending the full length of each rail, and operates to deaden the sound and absorbs a large portion of the jars and concussions incident to traffic over the rails; the twang of the rails being entirely eliminated by the use of said 3 strip. v

The soft wood strip 28 is entirely concealed within the rail structure, and will not be effected by rain or snow and other dcteriorating elements and will last indefinitely.

By this arrangement the vertical line of strain is directly through the center of the head 13, which for the time being is uppermost, and likewise through the center of the web 11 and tie flange 10, and any tendency to lateral displacement or overturning of the rails is effectually r l" i The coaction between the beads 16, clamp plates 17,20 and 23 and the shoulders 18, is an important feature, and materially in creases the stillness and deflection resisting quality of the rail.
