euARn RAIL STRUCTURE.

To all whom it may concern:

Be it known that I; ROBERT S. 'BOH N- NAN, a citizen of the United States of America, residing at Ensley, in the county of Jefferson and State of Alabama, have invented certain new and tusefullmprova ments in Guard-Rail Structures, of which the following is a specification.

This invention relates to guard rails for railway tracks, and its objects are to provide in a light, strong and compact body a'combination guard rail, foot guard and guard rail clamp, in which all wear from the Wheel flanges is received by a thin replaceable wear strip inset into the guard rail'and inclined away from the rail.

My improved guard rail clamp or fas tening' means contemplates the adjustment of the guard rail to 'the'traffic' rail by means Of akey to allOW for Various flange way dis tances andI provide this key with lugs Whichpengage the top and bottom of the rail base to hold the key'in position when spiked to the tie. To provide the maximum wedge shape and is notched to receive the fastening spike. To produce a guard rail that is exceedingly light but amply stronglforjthe' service required of it,]the guard rail proper terfacility of adjustment, Ithekey is given a minates at the level of the web forming the foot guard, being supported below by arches which span from crossftie to cross tie and have for their basesrail base plateswhich extend under the traffic rail. The c'enter plate has lugs which overhang the key and a slot v disposed to permit thekey spike to be driven in at any point where the key comes tofrest.

My invention also comprises the novel 'de tails of construction of the] guard rail which are moreparticu-larly pointed-out in the lap-j pended c1aims,reference being had to the accompanying drawings to illustrate the preferred embodiment only of the same.

In the drawings 1+ 1 Figure 1 shows my improved guard rail in plan view. j

Similar reference numerals refer to simi:

lar partsthroughout the drawings. The guard rail 1 is curved in plan view andis co supported at its centerby a narrow: integral web 2 which joins and is braced to a rail base plate 3 by theweb 4. The ends 5 of join to integral base-plates 6. rail is thus in efiect supported position by integral arches which spanthe crossties. a horizontal web 7 which at its ends is widened and curved downwardly to join the base plates 6, thus forming a foot guard.

The base plates 6 extend un'-. der the base ofthe'traffic rail and are protends under the base of each plate-prOJecting on one sidebf the guard rail sufficiently. to permit spikes to be readily driven through the notches 14 provided therefor to hold down along its edge beyond such rail it is prof vided with a raised shoulder l6set at an angle to the traflicrail and provided at each endwith lugs 17 and Y18 underwhich the wedgekey 19 is adapted to bedriven.

This key, as shownin F igQG, is provided A near its; center with. a, lug 20 adapted to overhang the base of the trafiic rail and near notch 22 and as the key is driven inbetween the shoulder 16 and the trafiie rail this spike notch 22 travels along over. a slot- 233 formed on the base plate 3 so that at any point where the key rcomeswte restf a spiket-24g be driven through notch 22 and slot 23 into the tie to fasten the key in position? The wedge key is driven in under thelugs 175111118 orthebasep1ate-3 t'o thedistance necessary to get the proper adjustment be tween'the guardrail and the traffic rail and I thev spike EM-will hold the key fixed in this position? The width of the foot guard webt is preferably-such as to 'stop short-eta. verti cal'plane' through the adjacent edge of the traflic rail tread", thus providingample elearaneefor'dii tand trash to pass out between the'web and the rail. Th'ends' of the guard rail proper are"curved' outwardly to catch andguide the wheel flangefthroughtheflange way and are curved downwardly to avoid' catching on any moving part of the train.

base plates

3 and 6,1 eliminate all superfluous metal without: sacrificing the necessary strengthfl The base plates, as shown in Fig. 3, maybe provided with downturned spuds 25fwhichare driven into the tiev and more firml secure the guardrail in position;

It is only necessary to cause the web 3 or center "of the base 'of'the guard rail to abut agains't ftheibasegof the traflic rail, as by :curving;t'he guard rail supports away from the"- tra'fiicfr ail, the ends are supported in such spaced position"from -"thetraflic rail as to greatly strengthenj'and brace thecenter of" a foot guard web, a guardrail rising above the guard" rail against Y lateral thrust strains.
