GUARD-RAIL STRUCTURE.

Specification of Letters Patent.

Patent ed Jan. 25, 1910.

Application filed May 28, 1909. Serial No. 498.996.

To all whom it may concern:

Be it known that l. Gunner: B. TAYLOR. a citizen of the l nited States. residing at. Philadelphia. county of Philadelphia. and State of Pennsylvania. have invented a new and useful Improvement in Guard -llail Structures. of which the following is a full. clear. and exact description. reference being bad to the accompanying drawings, which form a part of this specification.

The object of my invention is to provide a new guard rail and chair therefor adapted for use on railroads and especially under conditions wherein the guard rail acts not.

only a safety device but also to receive the direct lateral thrust of the car wheels. (xuard rails of this character are perhaps subject to the most severe usage on passenger railroads of large cities. such as subway roads and elevated roads. in which the curves are not only numerous but frequently very sharp.

The ordinary guard rail and chair. which approximately meets the re p1irements of ordinary long-distance steam railroads. fail utterly when applied to local transit roads. and the members of the guard structure. particularly the bolts by which the guard rail and main rail are tied together, are so frequently displaced and broken that their maintenance and replacement is a serious item of expense.

ln my invention. one preferred form of which is shown in the drawings and hereinafter described. a guard rail structure provided that is adapted to resist the strains and shocks incidental to its use under the most severe conditions.

hile the invention is more particularly designed for application to railroad tracks having sharp curves and over which trains travel at frequent intervals. it is also adapted for general use. not only in curves. but also at frogs. crossings and switches.

In the drawings: Figure l is a plan view of the structure. the guard rail being partly broken away; Fig. J is a side elevation of the structure; Fig. 3 is a section of part of the structure on the line 33 of Fig. 1; Fig. t is a similar section on the line ll of Fig. 1; Fig. 5 is an end view of the structure.

(a is the main rail and 7) the guard rail.

0 is the base plate of the chair.

Projecting upwardly from the base plate are two chair members, spaced apart. each the rear end of the web Hat. and the consisting of webs d and c extending longitudinally of the chair. and an upright rib f and an upwardly and forwardly extending rib 9 connecting the webs 1/ and c. The in her web (I of each chair member extends substantially to the rear of the outer web c and preferably to the rear end of the base plate. and the rear face of the rib alines with A third and horizontally extending rib o connects the webs (f and c for 'ardly ol' the rib g.

The guard rail comprises an elongated head and a relatively short web and is preferably of a peculiar cross-seetion approximately like that shown in the drawings. its head having a tlat lower face and an upper face sloping somewhat upwardly from its rear toward its front so as to present a relatively thick front to receive the thrust or impact of the wheel llanges. The web depends from the front of the head and is hollowed out or recessed in its front face to receive the hooked end of the hook bolt 71 hereinafter described. The bottom sur faces of the head and web are preferably rear face of the web slopes downwardly and rearwardly as show u. The webs (I to conform to the lower surfaces of the head and web. and the rear face of the web. of the guard rail. and the guard rail rests directly upon the webs r/ and c and the connecting rib (1'.

To hold the guard rail in position on the chair. the following means are provided.

7:. 11. are hook bolts extcndiu lon 'itudinallv of the chair through the ribs f and 1/ of the two chair members. their hooked ends curving upwardly and rearwardl v and extcmling into the recessed front face of the guard rail web. 9'. i. are nuts. on the rear of the bolts. that tighten against the webs c and ribs f of the rail chair members. 1- is a clamp having at its upper end a llange mertving the rear end of the guard rail head. while its lower end extends rearwardly and upwardly in hook form. The clamp Z' extends between the chair members and the rearwardly extending portion of its hooked end is inclined. in a transverse direction. somewhat to the horizontal. thereby forming a pocket having a. sloping tloor adapted to cooperate with the wedge m. l. l. are projections on the inner ribs (f. (I. of the two chair members. which projections hold the lower end of the clamp Zr from moving forwardly. m is a wedge adapted to be driven transversely into the pocket formed by the hooked lower end of the clamp A'. The length of the wedge corre sponds approxiniatel t to the width of the chair. The wel s 1/, ot the two chair menthers are cut away to receive the wedge. hen the wedge is driven, its upper horiaoutal etjlge engages the webs (l, 1/, while its inclined tower edge engages the inclined lower wall of the pocket formed by the hooked lower end of the clamp 11.

The rail chairs. with the hook bolts /t inserted. are placed in position under the main or running rail hetore the guard rail is placed, it lieing, of course, necessary to insert the hook bolts from the trout of the chair. .U'ter the guard rail is placed in position, the nuts 1' are tightened. thereby l'orcing the guard rail rearwardly against the ribs (I, w of the chair members. The clamp it is then applied and the wedge m driven. The wedge at performs the double function of holding down the rear end ot the head ol the guard rail and of locking the nuts 2' from turning. \Yhile the bolt /1. assists in holding the guard rail to the chair, and to that ex tent performs the Function of an ordinary t'astening bolt, it is not. likely to be broken in normal use. as practically no strain is imposed thereon. the entire strain being resisted rirlually solely by the chair members, the eonstruetion of which is such as to adapt them to receive and resist the vertical and rearward thrust to which the guard rail is exposed.

To hold the chair to the ties the t't'illowing means are provided: The outer or front end of the base plate 1' is provided with a lip a, between which and the contiguous tlange ot' the main rail are inserted two clips 0 which partly overhang said flange. Screw spikes extend through the clips and through slots in the base plate r into the tie I. A third elip r rests on the base plate 1: adjacent to the inner flange of the main rail and partly overhangs Said llange and is secured in ll lsition by a third screw spike s extending through the clip 1' and through a slot in the ba e plate into the tie If, owing to the wearing away of the. front face of the guard rail, it becomes desirable or necessary to move the guard rail forwardly to ard the main rail. to compensate for the wear, this may be done without forming new spike holes in the tie by removing the clips 0 and spikes y), loosening the spike .s'. sliding the chair toward the main rail. then substituting for the clips 0 other and wider clips whose spike holes, however, are at the same distance from their inner ends as are the spike holes of clips 0, and then rc-inserting the spikes p and tightening them and the spikes 8. Instead of substituting new clips 0 for those withdrawn, the clips 0 may be specially construt-ted to permit them to he continued in use notwithstanding the described shifting forward of the chair. Such a. specially constructed clip is disclosed in an application filed by me hlay 20, 1909, Serial No. still-K lil.

Different expcdient's for holding the wedge 'H/ in position may be adopted. For example, a. series of holes a may be formed in the upper face of the wedge, and. in the hole nearest the web (Z of one ot the chair members, after the wedge is driven in place, may be inserted a pin or rivet r.

A guard rail, supported and braced aS hereinbetore described, is well adapted to resist the most severe lateral thrust of the car wheels. Both the guard rail and the. main rail are entirely without bolt-holes, and the hook bolts and clamp are not sub jccted to strains or stresses of sutliciernt; severity to cause their breakage.

The guard rail structure hereinbefore de scribed has certain features of novelty in common with the guard rail structure set; forth in my said prior application filed May 20, 1909, and the invention common to both structures is claimed in certain of the claims oi said prior application. \Vhile 1 do not herein intend to confine myself to the details of construction hereiubefore emnnerated except where specifically claimed, it is not intended to cover herein the subject matter connno-n to the structures of both appliattions.
