Fig. 1 2 is a section on the line 12%12 Fig. 13 is a section on the line 13*13 15L a perspective yieyv of another modified form. t i i i i i f I The rails, which define the edges or sides ,of the road, sidewalk, curb, orthe like, are laid end to end,iaccording to wellknovvn practice, and said rails are formed from sheet metal, having the vertical Webs 10, the lovver outwardly-extending base flanges 11 rovided with the supplementary er secon ary upw dly ex e ing fl ng s 1 th pr e t lv-e t ndi g ad flan 13 P vided with the depending supplementary or secondary flanges 14. These rails differ in erosssection, however, for different uses and conditions, and the present improvements Can be modified accordingly, if neeessary.

In carrying out the invention there is provided a rail engaging member 115 to be disposed at the outer side of the Web 10 of a rail between the base flange 10 and tread flan er p tion 1 wh r y o a st in bracing the rail againstcollapsing under machine that is run over the rails.

The

member 15' ay be Q d flerent formations- As o n, it s q ha nel fo m, hav ng the b 6 dja ent to the w b 1 0 the r l and the outwardly-extending vertical flanges 17 The flangesl? abut the flanges 1 and 13 9 h ra l, and s ng fl have the slots 18 and 19at their lower and upper, ends, respectively, to engage the flanges 18 and 19, respectively, whereby to sectional details taken on i hold the member 15 in place againstthe rail. The member 15 is thus slidably assembledwith the rail andean be slid Ion,- e na lv f the a l t di f r n P si ions- The member 15 may also be used as a joint member abe -he edieee t n s .Qf tw rails, as seen in Fig. 1, whereby to hold the rail ends i alinernent against lateral er vertical SEIQIQNF W i i i i hettnmhe tlfi; 8 br ced Bi t the at ground or road bed, whereby to anchor the member and rail to the ground, and to also fasten the bars and 21 securely in place so as to brace the rail against transverse displacement. One or more braces may be used. I v

The bars 20 and '21 are clamped to the stake 24 by means of a bolt 25 engaging through the bars and stake. said bolt having a nut 26 thereon provided with a radial handle 27 for convenience in turning the nut to tighten or loosen the bolt. The stake 24 has a. vertical slot 28 through which the bolt 25 extends. and the bars 20and 21 are provided with longitudinal slots 29 at their outer ends through which said bolt extends. The bars thus cross one another and cross the stake, with the bolt 25 located at the intersection, and the bars and stakes are all slottedfor the relative adjustment'thereof bothpivotally and slidably.

hen the nut 26 is loosened. the stake 24 can be driven into the ground or road bed at a suitable point, the member 15 having beenslid longitudinally of the rail to the desired position, and the stake 24 can be ad.- justed slightly toward or away from the rail within the limits 'of the slots 29. The stake is preferably driven down vertically, although it can be driven into the ground at an angle. Then, .when the stake has been driven into place. the bolt 25 can he slid to the desired vertical position in the slot 28, and the nut 26 tightened to clamp the bars 20 and 21 and stake 24 together tightly. The bars are thus securely fastened to the stake to be anchored to the ground, so as to anchor the member 15 and rail to the ground, and to also brace said member and rail against transverse displacement. Not only can the stake be driven into the ground at ditferent angles, but the brace bars or rods 20 and-21 can be disposed at diflerent angles with the member 15 and stake. said bars being pivoted to the mem-' ber 15 tobe swung upwardly and 'downwardly, and. the bars and stake having pivotal and slidable connections by means of the common pivot and clamping bolt.

i As a resultof the adjustment of the bars 20 and 21 and stake 24, the device can not only be used to advantage on level ground or road bed'at the outer side of the rail, as seen in Fig. 1. but can be used where there is an embankment or rise in the ground or road bed at the outer side of the rail, as seen in Fig. 2, or where there is a ditch or ravine at the outer side of the rail, as

seen in Fig. 3. In fact, as shown in Fig.

3, the bolt 25 could be down lower, and even below the horizontal plane of the base flange 11 of the rail, and in some cases the bolt25 may be above the horizontal plane braces or bars 20 and 21 to adjust them selveswith the rail.

Fig. 5 shows a modification wherein the 'railengaging member 15' has the web 16 and flanges 17', the lower. portions of said flanges being shaped, as at 18 to fit between the web 10 and flange 12 of the rail, and plates ,or pieces 19 are riveted or otherwise secured to the flanges 17' at the upper end ofthe member 15' and have the slots 19' to engage the flange 14 of the rail. The lower bar 20 is pivoted. as at 22,'t0 one flange 17 while the upper bar 21 is pivoted, as at 23, to thecorres'ponding plate 19".

Figs. 6. 7 8 and 9 illustrate a third form of the invention. The rail engaging member 15* has the inclined portion 17". the lower end of which is adapted to seat in the corner or bend between the base flange 11" and secondary flange 12 of the rail. the base flange 11 being wider than the tread flange 13. as shown. The member 15 is provided at the upper end of the portion 17 with a head 16" to fit snugly under and against the flange 13 between the web 10 and flange 14. wherebythe member 15 braces the rail. Oflset plates or pieces 18 and 19 are riveted or otherwise secured to the member 15 near the lower and upper ends thereof. to overlap'the flanges 12 and 14 on the outside. whereby to assist in holding the member 15 in position.

The brace bars 20 and 21" have the slots 29 to engage the clamping bolt 25 which extends through the vertical slot 28 of the stake 24". a. nut 26 being threaded on the bolt. the same as in the constructions hereinbefore described, for clamping the bars to the stake. The stake 24 is composed of angle iron as shown.

The bars or braces 20' and 21" are connected bv detachable and pivot joints with the member 15. Thus, the bars are provided near their inner ends with notches 30 in their opposite edges providing the portions 31 of-reduced width and of circular outline between said notches. The member has vertical slots 32 therein nearits upper and lower ends, and circular openings 33between the ends of said slots. The bars and 21 are twisted intern'iediate their ends, as at 34,

from the stake, said bars can be turned at right angles about their axes, so that the inner ends of the bars are ina vertical plane, thereby permitting the inner ends of the bars to be inserted into the vertical slots 32. The

bars are then turned. whereby to lock the inner end portions of the bars behind the member 15 with the circular portions 31 fitting in the openings 33 to provide flexible or universal joints between the bars and rail engaging member, permitting the barsto be swung or adjusted upwardly and downwardly to diflerent angles and also enabling said bars to be adjusted to different angles relatively to the rail longitudinally of the rail. The bars are clamped to the stake 24 by the -bolt25, after the stake has been driven into place and the braces or bars adjusted Thebars are thus securely fastened to the stake, and this will also prevent the bars from turning inthe openings 33, thereby retaining the bars in engagement with the member 15. The bars can be adjusted relatively to the member 15 and detached from said member, when the bars are loosened or detached from the stake, respectively. The looscningot' the bolt will permit the bars to slide and swing on theb olt 25, and when the bars are completely detached from the iii) stake, the bars can be turned in order to withdraw the inner ends thereof out of the slots 82. y

Fig. 10 shows the rail engaging member 15 without the plates 18 and 19, and the brace or bars 20 and .2], aredetachably and pirotally connected with said member in the same manner as shown in Figs. 6 to 8, inclusive, The bar 21* extends across and is secured to the stake 24 by means of the bolt 25, and the bar 20? extends acrossthebar 21 between the stake and rail. The bar 20 -has a longitudinal slot 29 receiving a bolt 25 carried by the bar 21", and a nut Qfi-Pis threaded on said bolt and has a handle 27! similar to the nut 26. r

F 11, 12 and 13 show the rail engaging member 15 composed of the inclined . plates 17 and 35 fastened together d'etacllably by the bolts 36, the lower end of the plate 17 being adapted to seat in the corner or bend between the flanges 11 and 12 of the rail, and said plate 17 having theheaifil 16? to fit between the web 10 and flange -14 of the rail under and against the flange 13. The lower and upper ends of the plate35 are offset, as

at 18 end 19F, to over ap hefianges 12 and 14 On the utside. i

The bars 209 and 21, which are clamped to the stake 24 in the same manner as hereinbefore described,have the balls 31 at their inner ends to provide for ball and socket connections between said bars and the rail engaging member 15. The plates 17 and 35 have opposite recessed or socket portions 32 receiving the balls 31 between them, to provide the ball and socket connections, and the portions 32 of the outer plate 35 having openings 33 through which the bars extend to ermit said bars to be swung vertically an horizontally relatively to the member 15. The plate 35 has a slot 37 extending at its ends to the openings 33, and provided between, its ends with an enlarged opening 38, in order that the bars canbe detached from the member 15 when the plate 35 is loosened or detached from the plate 17; The 1 .slot 37 enables the bars to he slid therein and the opening 38 is sufliciently large for the passage of the balls 31. Fig. 14 shows the bars or 21 clamped by separate bolts 25 to the stake 24, whereby the bars can be adjusted independently. This arrangement also enables the rail to be supported abovethe road bed or surface, as shown, the bars 20 and 21 forming a supporting bracket to support the rail from the stake. The'railengaging member 15 to which the bars are pivoted, asat 22 and 23, respectively, has its upperend fitting between the web 10 and flange 1.4 of

the rail under and against the flange 13, with the lower end of the member 15 provided with a slot 18 to engage the flange 1,2.
