COMPOUND RAIL.

Application. filed November 21, 1925.; Serial Nd. 70,521;

To all whom it may concern: a

Be it known that I, GEORGE TVzMULLER,

citizen oft-he United States, residing at 'olVashington, intheDistrict of Columbia,

have invented certain new and'nsefulImw provements in Compound Balls, of which the'following is a specification.

This invention relates to improvements in railway rails, and'has for onevofits objects to provide a rail of laminated and continuous construction and without transverse joints, and consequently clamp plates or like holding means.

Another object of the invention isto .provide a device of thischaracter including a reversible ball portionlso that when one side of the ball is worn the bearing portion can be reversed to present the unworn portion to the action of'the wheels of the rolling stock.

Another object of the invention is to pro- Figure 10 is a side elevationof a section,

of a. bodyportion of'the improved rail.

Figure 11 is a sideelevation of a portion of a bearing, portion of the improved rail. Figure 12 is a plan View on a reduced scale, of a portion of one of theimproved rails with the head or l'oad'carrying members in section on the line 12-912 of Figure 1.

The improved rail is constructed of plurality of longitudinally directed members ofimifor'm length, and arranged in series, the units of each series disposed end to end with their contiguous ends intermediate t'heend'sof the adjoining units, where by a continuous rail is produced and without transverse oints, thus eliminating clamp or fish plates, andprovidinga rail which will not be deflected by the rollingv stock.

The improved rail comprises aplurality of body members each including. a tie flange 10 of the usual form andanupstandmg web without it the members 1011l disposed end to end,

' intervals to hold the units together.

By thlsumeans an efiicientjcompound rail 11, a bearing member including a ball pertion 12' and a downwardly directed web 13,

- PATENT, arm 15:; V

and a clamping plate member including, an

upstanding web 14 and an outwardly 'directed rib or foot portion 15. The clampgng plate-member is not shown in Figures an 9- o 7 member 14 engages the other face of the web 13, as shown; The several members are of the same length, for instance, thirty feet,

the members 12 -13 disposed end to end,

and the members 1415 likewise disposed i I e d to nd- I The confronting ends of the bearing members 12-13 are located about one third of the length of the body members, or nearer one end thereof than the other, while the confronting ends of the, holding members are located about two thirdsofthe length of the body members and one third the length of the bearing member. 1 Thus if the rail units. are each thirty feet long, which is the usual length of railway rails, the confronting ends of the several units will be located at ten foot intervals as illustratedin Fig me 12. p I V Clamp bolts 16 areempl'oyed at suitable is produced and uniformly supported throughout for the entire length and insures a smooth running of the rolling stock and free from jolts and jars.

In Figuresl to 9,. inclusive, various forms of the rail units are shown; I

In Figure I the web 11 is formed with a longitudinally directed channel or seat 17,

while the holding member 14 is formed. with a like longitudinal seat" or'channel" 18, the seats adapted to receive outwardly directed beads'19 on the lower edge of the web'13'.

The beads and the channels coact to effece tually hold the bearing member from upward displacement and likewise relieve the clamp bolts from shearing strains.

In Figure 2 the web 13 of the bearing member is uniformly enlarged toward the lower edge'and the opposite sides provided with longitudinally directed V-shaped serrations or grooves 17*,and the confronting faces of the web 11 and the holding member The webs ll and 13 engage face to face atone side of the latter, and the holding, v

I l are provided respectively with corresponding serrations or grooves 18 and 19" to engage the grooves 17. By this arrangement the grip between the parts is materiall y strengthened and reinforced.

In Figure 3, the web 13 tapers in reversely curved lines toward the lower edge, and the confronting faces of the web 1]. and the member 14- are correspondingly curved, and the contacting faces provided with V-shaped channels or grooves, the same as in Figure 2.

In Figure -'l the channels or grooves are in truncated cone shape transversely, and in Figure 5 the channels or grooves are semicircular.

In Figure (3 the channels or grooves are in saw tooth shape.

In Figures 2, 8 and a, the tie flange portion 10 of the body is formed with a longitudinally directed seat 2) to receive the outer edge of the toe portion 15 of the clamping plate member, to provide an eiiectual support against lateral displacement.

In Figlu'e 7, the tie flange portion it] is provided with an undercut seat 211., and the terminal of the toe port-ion formed with a lip member 29 to enter the undercut seat, and thus provide ell'ectual means for preventing vertical i'lisplacement.

In Figures 8 and 9, the web 13 is shown supported againstthe web ll directly, and without employing the holding member 14 m In the structure illust ated in Figure 8, the V-shaped grooves or channels are employed, and in Figure 9, also the web 13 is shown with a single bead 19 to engage in the channel 17 of the web 11.

In Figures .l, '2, and 7, the upper edge of the web 11 is beveled upwardly and inwardly as shown at 23, the upper edge of the web It is also beveled upwardly and inwardly as shown at 23, while the lower faces of the ball portion 12, are beveled inwardly and upwardly as shown at 24:, to

correspond to and closely engage the beveled portions 28 and 23.

By this means the downward pressure exerted on the ball portions 12 of the rails creates an inwardly directed force to draw the portions ll and 1 toward each other, and the greater the pressure the greater the grip, and spreading action is effectually eliminated.

In Figures 1, 2, 7, 8 and 9, the upper edge of the web 11 is reinforced by an outwardly projecting head or rib while the 1l'l8l1l ber id, as shown in Figures 1,, 2 and 7, is also provided with a like strengthening rib or head 26.

From the foregoing it is believed that the construction, operation and advantages of the invention may be readily understood by those skilled in the art and it is obvious that changes may be made in the details disclosed without departing from the spirit oi? the invention as expressed in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
