Thepresent invention relates'to; guardrails for railway track installations and consists o'fan improved guard railconstruction comprising .as a primary unit :an integral guard railcasting adaptedto'bemade olf manganese steel and of a form to berigi dly secured'in positionlupon the ties without the use ofbolts, clamps or specia l securing devices. .It is furthero'f an improved formtopermit of the use therewith, in accordance with an important feature ofthe.present invention, of separable bracing. members which may be economically made from commercial rolled steel and ar- .ranged-to be operative-to resist the severe lat- 'eral thrusts to which the head 0f the guard rail is subjected.

A1r-importantpbject of my present improvements is to effect-a substantial-economy inthecompleted structure, first, as the result of the employment of the reduced weight'ot the managanese or other high grade steel of which the guard rail proper is formed, with further savings incidental to the casting of a more uniform section, while offering additlonal economies incidental to the use of the separable bracing members.

The described and other valuable features of the present invention will be more fully understood by reference to the accompanying drawings wherein like reference numerals are applied to the corresponding parts in the several views.

In the drawings Figure l is a plan view of a guard rail made in accordance with the present invention.

In accordance with the importantrfeature of the present invention, the inner side of the guardrail head is formed with recesses '15 in its underportion,,positionedwith relation'to the ties. Fitted to said recesses there are provided separable bracing members 16, in- I wardlyand downwardly.inclined,and having angularly disposed toe portions 17 provided with the spike apertures '18 for spikingtothe ties. Theprovision of the separ'able'bracing members 16 which may be desirably formed of standard; rolled steel, :ascommerCialIy; obtainable, allows of inexpensively l'profviding for adequate bracing of theguard railagainst the severe lateral thrusts rand therebyv opposes the lateral thrusts .tendingetogtilt 'or turn over the v guard rail section.

Ash-est shown: inwFigureQfthe are desirablyslightlyelengated w ith rla tion to the width of the bracing members, thereby allowing a limited longitudinal adjustability of the bracing members, which offers theadvant-age of slightly shifting the position of the braces upon the ties for re spiking when occasion occurs.

My improved guard rail structure accordingly possesses the important advantages of an integral manganese guard rail, while eliminating the excessive costs incidental to the casting of the inner bracing members as an integral part of the guard rail proper.
