SPECIFICATION forming pare of Letters Patent No. 649,067, dated May s, 1900.

Application iiled November 9, 1899. Serial No. 736,425. (No model.)

To all whom t 1v1/ty concern:

Beit known that I, JOHN MURPHY, a citizen of the United States, residing at San Antonio, in the county of BeXar and State of TeXas,have invented a new and useful Guard- Rail, of which the following isa specification.

This invention relates to guard-rails for use in connection with frogs or switches, although it will of course be understood that it may be employed with equal efficiency upon curves and in other places where guard-rails are commonly used.

One object of the invention is to provide a construction in which the guard-rail will be firmly held in place, so as not to spread, a further object being to provide a construction in which the loosening of the spikes of the guardrail, with the dangers incident thereto, will be prevented.

An additional object is to provide means for holding the guard-rail against endwise movement and also for providing end pieces therefor which will result in a gradual slope at the ends of the guard-rail, to prevent striking of parts 0f a moving train thereagainst.

Still another object of the invention is to provide a modification which is particularly adapted for use Where the web of the guardrail is shorter than that of the track-rail and which construction is employed when the base or flange of the track-rail is so wide as to prevent the guard-rail lying sufficiently close to the tread of the track-rail.

In the drawings forming a portion of this specification, and in which similar numerals of reference designate like and corresponding parts in the several views, Figure 1 is a plan view showing portions of track and guard rails arranged and connected in accordance with this invention. Fig. 2 is a section on line 2 2 of Fig. 1. Fig. 3 is a plan view showing a modification of the structure as applied when the guard-rail is of less depth than the track-rail. Fig. 4 is a section on line 4 4 of Fig. 3. Fig. 5 is a section on line 5 5 of Fig. 3. Fig. 6 is a detail perspective showing the supplemental wedge-block employed in the construction of the modification. Fig. 7 is a view similar to Fig. 1 and showing the application of the end anchor for the guard-rail. Fig. 8 is a detail perspective View showing the end piece or anchor for the guard-rail.

Fig. 9 is a section on line 9 9 of Fig. 7. Fig. 10 is a transverse section of the guard-rail on.

line 10 10 of Fig. 7 and showing the engagement of the fingers of `the end piece or anchor therewith.

Referring now to the drawings, and more particularly to Figs. l and 2, 10 represents a track-rail which is spiked to the ties in the usual manner and adjacent which is arranged a guard-rail 11, the dimensions of vwhich are substantially as those of the rail'lO and which guardrail is likewise spiked in position. In order to hold the guard-rail 11 against dis'- placement-that is, the lifting of one side of its flange from the tie and permitting the working of sand and dirt in under the side of the flange to thus hold the supplemental rail out of its operative position-these rails 10 and 11 are properly'spaced and have a spacing-block 12 disposed between them. This spacing-block 12is adapted to hold the rails against inward movement under the influence of the clamping action of a clampingchair 13 and which chair and its connect-ed parts hold the rails against separation. The spacing-block 12 is so shaped that its lower convened face 14 will lie upon the webs of the rails 10 and 11, while its side faces 15 and 16 will lie against the inner faces of the webs of the rails. The upper face of the block 12 is concaved, as shown at 17, the chord of the concavity being less than the width of the block to form shoulders 18 and 19, which rest upon the under faces of the treads of the rails. The chair 13is substantially U-shaped, with its upwardly-extending sides 20 and 21 disposed convergingly. Between the upwardly-extending side 2O and the web of the rail 10 is disposed a clamping-block 22, which is U-shaped in horizontal section, the projecting ends 23 and 24 of this block lying upon the opposite side faces I of the portion 20, as indicated. By this means the block 22 is held against longitudinal displacement, and when the chair is operated to draw the block 22 beneath the head of the rail 10 said block will be held against upward displacement and will be 'fined in position. To thus move the chair laterally, the side 2l thereof is disposed IOO at an angle to the side 20, and consequently to the rail 11, and between the side 2l and the web of the rail 11 is disposed a wedgeblock 24, adapted to lit over the liange of the rail 11 and to conform to the shape of the parts against which it impinges. A longitudinal slot 26 is formed in the block 24 and which slot registers with a perforation in the base of the chair 13. Passed upwardly through the perforation and slot is a bolt 27, having a clamping-nut 28, and thus after the wedgeblock 24 has been forced in to draw the parts tightly together, as will be readily understood, the nut 2S may be tightened, and the bolt 27 will thus act to hold the parts in position. With this construction it willbe seen that the spacing block 12 holds the rails against inward movement, while the blocks 22 and 24, in connection with the chair 13, hold the rails against outward displacement, the result being an exceedingly-firm structure As shown in Fig. 2 of the drawings, in order to hold the wedge-block 12 against longitudinal displacement a bolt 30 may be passed through the web of either of the rails and at each end of the wedge-block, this bolt at each end thus acting as a stop.

Referring now to Figs. 3,4, 5, and 6, in this construction the chair 3l is the same in form as thechair'13, in this construction, however, the guard-rail 32 being of lesser depth than the rail 33 to permit the flange of the guardrail to set inwardly over the flange of the track-rail, and thus to bring the heads or treads of the rail into their proper correlative positions. With this construction the spacing-block 34 has lesser depth, while the shoulder 35, which rests against the under side of the tread of the guard-rail, lies in a plane above the plane of the shoulder 35, which engages with the under side of the tread of the track-rail 33. In this construction also there is employed a supplemental wedge-block or support 36, which is adapted to lie upon the upper face of the chair 31 and the forward end of which is cut away at 37 to fit upon the adjacent edge of the flange of the rail 33. The outer end of this block 3G is recessed, as shown at 38, which receives the side 39 of the chair, theends of the resultant bifurcations 40 and 41 being continued downwardly to further strengthen the structure. Upon this block or rest 3G the guard-rail 32 is seated, while a wedge-block 42 is engaged with the guard-rail and is disposed between it and the side 39 of the chair. This side 39 converges toward the guard-rail in order that the longitudinal movement of the block 42 will have the desired wedging action, and in order to hold the block 42 in position a bolt 43 is passed upwardly through a perforation in the chair 31 and a slot 44 in the wedge-block and is provided with a clamping-nut 45.

It is of course necessary in the use of the smaller guard-rail to provide means for holding it at the proper elevation, and for this purpose a chair 50 is disposed upon each of the ties 51, and this chair has its inner end cut away, as shown at Fig. 52, to receive the edge of theliange of the track-rail Upon the chair 50 is "disposed the guard-rail, the chair being held upon the tie by means of spikes 53, a portion of which are disposed to engage the flange of the guard-rail.

It will of course be understood that in practice the parts of the structure may be made of any suitable material and that the specific shape thereof may be altered to adapt them to different conditions, and also that various other modifications may be made without departing from the spirit of the invention.

In Figs. 7, S, 9, and 10 of the drawings lthere is shown the end piece or anchor employed to prevent longitudinal movement of the guard-rail. This anchor or end piece comprises a flanged base G0, one end of which is enlarged and flattened, as shown at 6l, and is provided with spike-receivin g openings G2. Upon the base G0 is a web G3, which supports the tread G4, similar to the tread of the guardrail, and which tread projects rearwardly in the direction of the base and meets the base at the enlarged end G1. Extending from the web G3, longitudinally thereof and mutually parallel, are lingers 65 and G6, which are sep-` arated by an interspace 67, equal in width to the web 63, which is equal in width to the web 64 of the guard-rail. [he height of the end piece or anchor at its highest end, where the fingers are located, is equal to the height of the guard-rail, and in the application of this device it is so disposed that the ends of the tread portion 64 and web 63 and the base will lie closely against the corresponding .portions at the end of the guard-rail and with the fingers 65 and 6G lying closely against the web of the guard-rail. In this position the fingers hold the end piece or anchor against lateral displacement at one end, while lateral displacement at the other end and longitudinal displacement of the end piece or anchor is prevented by spikes which are 'driven through openings G2 and into the tie.

that while the clamp hereinbefore described holds the guard-rail against spreading with` respect to the track-rail the anchor or end piece holds the guard-rail against longitudinal movement, and at the same time its slanting construction presents a gradual incline from the tie-surface of the tread of the guardrail, so that a brake-beam or other portion of the train in striking this end piece will 'ride upwardly and onto the guard-rail without injury and without displacing any of the parts.
