GUARD-RAIL FOR RAILW'AY-BRIDGES.

Specification of Lettersfatent.

iatented Jan. 25, 1921.

Application filed August 6, 1920. Serial No. 401,757.

To all whom it may concern:

Be it known that I, WILLARD Hannrson ELLIS, a citizen of the United States, and a resident of Cheyenne, in the county of Laramic and Stateof lVyoming, have invented certain new and useful Improvements in Guard-Rails forR-ailway-Bridges, of which the following is a specification. 7

My invention relates to railway bridges and more particularly to guard rails therefor, a purpose of my invention being the provision of a simple nd inexpensive guard rail which eiiectively secures the deck ties in proper spaced relation on the girders, and which permits removal and replacing thereof when substituting new ties without detriment to the guard rails.

I will describe one form of guard rail embodying my invention and will then point out the novel features thereof in claims.

In the accompanying drawings:

Figure 1 is a fragmentary view showing in top plan one form of railway bridge having applied thereto one form of guard ra1l embodyingmy invention.

Fig. 2 is a vertical sectional vlew taken on the line 22 of Fig. 1. i

Fig. 3 is a fragmentary detail view showing in perspective one of the guard rails shown in Fig. 1.

Referring specifically to the drawings, in which similar reference characters refer to similar parts, G designates a pair of girders, each of which, as shown in Fig. 2, is in the form of an I-beam. Supported upon and extending transversely of .the girders G are wooden ties T of the ordinary form, and supported upon the latter are the rails R or a railway track. The guard rails forming the subject matter of my invention are designated at D, such rails being arranged transversely of and adjacent the opposite ends of the ties T. As illustrated to advantage in Fig. 3, each guard rail is formed from an angle bar of suitable metal, the lower web portion of which is recessed at intervals along its longitudinal edge and then split longitudinally at intervals, such split portions communicating with the recesses and thus providing a plurality of companion lugs L and L throughout the length off the guard rails. The lugs L and L are arranged in pairs, with the lugs of each pair being bent downwardly at right angles and in opposite directions so as to embrace the the applied position of each of the guard rails D, each pair of lugs L and L engages atle T, the guard rail being secured as a unit upon the tie and to the corresponding girder by means of hooked end bolts 13..

'lhe upper or threaded end of each bolt B carries a nut 15 which, during the application of the bolt, is removed and applied after the bolt shank has been passed through a tie. As shown in Figs. 1 and 2, a bolt B is provided at alternate ties, the bolt extending through the bottom web of the guard rail and through the corresponding tie T its hooked end engaging the under side of the upper flanged edge of the girder G and se curely locked in such position by a vertical adjustment of the bolt through the medium of the nut 15. lVith both of the guard rails secured in this manner, it will be clear that relative movement of the guard rails with respect to the ties is prevented while the guard rails and ties are securely held to the girders G against movement in anydirection. The lugs L by embracing the opposite sides of the tie provide further means for securing the ties in spaced relation at all times so as to provide an efficient support for the rails R- of the railway track.

It is to be particularly noted that because of the construction or" theguard rails and the manner in which they. are applied to the ties and girders that they can be readily removed from the same when it is necessary to substitute new ties, for those which have become worn and useless, without in any way distorting the guard rail so that.

they can be re-applied to the ties when functioning in the same successful manner.

.Although I have herein shown and described only one form of guard railand onlyone means for securing the rails and girders to a railway bridge, it is to be understood that various changes and modifications may be made herein without departing from the spirit of the invention and the spirit and scope of the appended claims.

What I. claim is 2' I p 1. A guard rail comprising, a barrecessed at intervals along one longitudinal edge and split longitudinally at intervals to provide lugs, said lugs being bent at right angles in the plane of the bar and arranged n pairs, withthe lugs of each pair spaced apart opposite sides of the corresponding tie. In 2.. A guard rail comprising, an angle bar 1 havingone Web thereof formed with right said ties, each of said guard rails comprising 10 i angularly disposed lugs, said lugs being a1- a bar formed With depending lugs, said lugs ranged in pairs with the lugs of each pair 7 being arranged in pairs with the lugs of each spaced apart to accommodate a railway tie pair embracing the opposite sides of one 5 and to embrace the opposite sides thereof. of the railway ties, and hooked end bolts 3. Agrailway bridge comprising, in comextending through said bars and ties and 15 bination, girders, ties arranged at intervals having the hooked ends thereof engaging and extending transversely of the girders, said girders. rails supported on said ties, guard rails on WILLARDHARRISON ELLIS.
