' Application filed August 10, 1927. seria1'no.ai' 1,e02. V

VMore particularly, my presentinvention relates to railway track construction which includes the use of individual rail supports which do not span the space between the parallel rails of the track nor support both of the parallel rails thereof, as do the cross ties now in common use.

It is recognized in the railway track'art pears in the use of the individual rail supports, as it does also when cross-ties are a so used, andshould be counteracted.

For this-purpose I have invented the cruciform rail supports which form the subject matter of my application for Letters Patentfiledin the United States Patent .Oflice on November-11, 1926, Serial Number 147,634 v v i In the use of these supports actual service I have discovered a tendency toward an outward shifting of, the supports relative to the axis of the tracks whichienerts tensionstrains onrthe tie-rods which arej usuallyprovided to hold the rails inparallelism.

- I have therefore made a further improve- "ment in my cruclform ra l supports whlch prevents such outward shifting and causes the strains which tend to causethesame-to be assumed by theballast orroad bed.

I prefer to providemy cruciform rail support with a larger bearing area on the inside of therail as the roll ngor t pping forces which are exerted-toward the "axis of the track are greater than those exertediin the opposite direction. I'also provide an improved metallic crete or other material of whichI form my rail support.

Other novel features of construction; and also of arrangement of parts, Wlll appear from the following description.

f Inthe accompanying drawings, wherein I have illustrated the best embodimentofthe principles of my invention now known to me, Fig. 1 is a plan view showing'my improved rail supports in use to support the parallel rails. of a track; Fig. 2 is an en- 'gitudinally of the rail to rolling of the rail is the greater. e To counteract. the tendency, already rerail support I to be: thrust rein 'forc'ement which is embedded in the conlarged planviewiof one of said supports,

Fig, 3 is a side elevation of the support better illustration the two part mat being partially broken away for thejsake of looking from the axis of the t1*ack; Fig.4

is an end view of the support, andFigf 5 shows in enlarged perspective the metal skeleton which is embedded the support to reinforce the latter. f

Referring to the drawings, land 1? represent the parallel rails of the track, each i supported from beneath'by' the individual rail supports 2, said opposite supports be mg unconnected with each other and being embedded in the ballast. t i

- The supports 2 are-substantiallyform, the longitudinal leg orbeam 8 being the rail supporting memberiextending lon v providean extended support for the latter. i I

in material of V The twotransversely disposed legs 4"and I 5 which extend inwardly toward the axis of the track and outwardly inv the opposite direction, respectively, asshown in Fig. l,

are the outer t and innerr stabilizinglegs.

The inner stabilizing vleg 4 is preferably givena larger bearing area on theiballast or road bed as 'the tendency toward inward ferred to, of the outwardly awayfrom the axis of. the track,

form the inner stabilizing'leg 4 of such" 7 shape that it will bind in the ballast and re the saidleg of what may be termed fishtail shape so that will be wedged in the ballastiand will thus anchor the rail support p against outward. movement.- v r 7 The leg 4 has preferably about one-and (One-half e g area. on the road-bed thattheleg s ag, v a a The top surfa'cesof the 1egs;4 and 5 are preferably at a lowerlevel than that of the longitudinal beam 3 and the top edges of the supportar-e preferablybeveled as shown.

'The mats are-both preferably made of resilient material, such as rubber, asphalt composition and the like, or a V combination thereof, the under mat being the more elastic than the upper mat.

The ends of the bars" 1 1 are'connecte'd by the cross bars 16which contact with the under-v sides of the bars 14 and are welded or otherwise secured thereto. Also the en'd's'of the bars 15 are connected by the cross bars 17 which contact with the lower surfaces of the vlatter and are welded or otherwise secured thereto. .The bars 14 at the inner side of the support have also an extra'connecting Said cushion means preferably. corn-' secured-to fore the skeleton is embedded in the con The ends of the lower bars 211 are connected to the cross-bars 12 by the vering legs extending "supports for gles to the cross-bar 18', and the bars 15 an extra cross bar 19 to further brace the inner stabilizing leg of the rail support. Posts 20 have their lower ends stepped on the bars 15 and their upper ends abutting against the under surfacesof the cross-bars 16, the ends of the posts being welded or otherwise secured in v place.

Additional posts 21 are interposed between the intermediate cross-bar 13 and the bars 15' with their ends welded or otherwlse secured in place. r

Also posts, 22 are interposed between the bars 14 and 15 where they intersect with the bars 10 and 11, respectively.

The two central bars 10 are so positionedas to extend longitudinally of the beam 3 beneath the seat 6 and I edge of the same, and are located close to the floor of said seat to directly assume the thrusts-and jolts incident to traffic on the rails, a relatively thin coveringof concrete being provided, suficient to protect the metal from oxidizing. Thus the metal reinfor'cement efiectually relieves the concrete and prevents its rupture, crushing or fracture.

adj acent to each lateral c The outer bars 10 and .11 are positioned adjacent to the bases of the stabilizing legs t and .5, and thus prevent fracture or cracking "longitudinally of the rail supporting beam 3.
