GUARD-IRON FOR ELEVATED RAILROADS.

Application led June 29,

To all whom it may concern:

Be it known that we, DANIEL M. PFAUTZ g and JOHN Lnwis LUCKENBACH, citizens ol' the United States, residing at Philadelphia, in the county oi' Philadelphia and State o1' Pennsylvania, have invented certain new and use'l'ul Improvements in Guard-Irons Vlor Elevated Railroads, ol' which the following is a speciiication.

Our invention relates to elevated structures carrying suspended cars and particularly to guard plates, irons or rails designed to prevent the derailing o1' a train ci' suspended cars.

The object of our invention is to prevent the suspending wheels or a car ol' a suspended train Vfrom lifting from the rails, and provide ineans i'or directing the wheels oi`l suoli a car again upon the track rails iil by chance they should be lifted l'roin the tracks by a nievenient independent o1' the car. In other words, our inain object is to prevent a car l'roni being dislodged in any way Vtroni the rails and falling ironi the elevated structure.

Our invention consists in the arrangement of parts and the constructional details shown in the accompanying drawings and particularly set i'orth in the claiins appended.

In the drawings, Figure 1, is a transverse section of the lower chord ol' an elevated structure, the vertical upper chord support and laterally proj eoting, rail supporting brackets being in elevation. Fig. 2, is a like view to Fig. 1, showing also an inside antilifting plate. Fig. 3, is a like view showing the combination of a lateral guard, an antilifting plate, and an inside wheel guard. Fig. L1, is a like view to Fig. 3, showing another forni of lateral wheel guard. Fig. 5, is a horizontal section taken on line x-a: ol' Fig. 1. `Fig. 6, is a side elevation oi a rail supporting bracket plate carrying the lateral wheel guards.

Like reference characters throughout the several views designate like parts.

Our invention pertains particularly to elevated structures oi a general character described in IJ-atent No. 841436, ot' January 15, 1907, granted to Daniel M. Pl'autz, wherein the car is suspended frein wheels which travel on upper tracks carrie-d upon the overhead structure, the support from the car depend- Speccaton of Letters Patent.

i ing between the track rails ll'roni wheels which run upon the two overhead separated rails. The special forni ot' structure to which we have particularly applied our guard rails 1s shown in another application l'or patent by us now pending, Serial No. 440,810, i'iled June 29, 1908. In such structure as this, it is particularly necessary to guard against the truck dropping l'roni the wheels, the wheels leaving the track, the oar rising upward against the elevated structure or the wheels rising independently ci the oar l'roni the track and not being properly returned thereon. The combination of the various guard rails or irons herewith shown, are designed to prevent such accidents in a railway structure of the character described, but, of course are applicable to sonic extent to other elevated structures oll a diiierent character.

In the drawings we have shown the lower chord ot' an elevated structure supporting one o1l the rails oi the track-#it being ol' course understood that the opposite side oi' the structure is the saine and provided with like rail supporting brackets, beains, etc.

The elevated structure as far we have shown it in the drawings, consists oi a longitudinal beain A, forming the lower chord of the structure riveted to vertical members composed of angle irons. There are four of these vertical angle irons B', B, B, 16, as shown in Between the laterally projecting flanges of these angle irons is riveted the bracket plate C, shown in detail in Fig. o, of an approximate L-shape. The bracket plate extends down below the vertical angle irons E', B, Bm, BW, and its lower end is bent at right angles to forni a iiangc O, which is riveted to an angle iron A, riveted in turn to the lower inargin of the beain A. 'Ihere are two ci the angle irons A', opposed to each other and connected by a stiiiening plate A Frein the lower chord thus formed is supported the third or contact rail and its insulating blocks. The third-rail support is fully dcscribcd in another application iiled coincident with this, Serial No. 440,808,1iled June 29,1908.

The bracket plate C, iorins the support for the track rail, and in order to stillen it we provide angle irons E, located on a level with the upper margin. of the outwardly projecting portion C, of the bracket, and on these angle irons E, 1s carried the sounddeadening plate F, on which rests the rail L.

The base of the rail is clamped to the structure by clamping and adjusting bolts M, which also form the subject of another application Serial No. 440,809, led June 29, 1908. This general structure above described is illustrated. in all the views as the rail supporting structure.

Our present invention relates to the guard rails, plates or irons, and in Fig. l, we show a lateral wheel guard for the outside of the wheel designed to guide the wheel back upon the rail if at any chance the wheel should risel therefrom.

The guard consists of a longitudinal plate 2, which is inclined from its upper edge downwardly and inwardly toward the tread of the rail. This plate along its length is supported on the inclined edge of the bracket C, the plate being also riveted to opposed angle irons 8, which in turn are riveted to the web of angle irons B, BW, as shown clearly in Fig. 5. The upper margin of the guard plate is vertical and the plate is then bent at a slight angle as shown in the sectional views, the lower edge of the plate being just below the tread of the track rail. If the wheel lifts from the track it will strike against the face of the guard plate and will be guided back on to the track. This guard will have the same cHect if the wheel supporting structure lifts independently of the wheel, the projecting guard arm O, carried thereby striking against the plate and being guided back on to the track.

In Fig. 2, we show a combination of a lateral guard plate 2, with a guard .plate acting to prevent the suspended car from rising independentlyT or with the wheels. This anti-lifting guard consists of a longitudinal iron 4, preferably an angle iron having an upwardly extending flange 4, by which it is connected to the end of bracket E. In Figs. 3 and 4, we show this angle iron inturned and independent, but, in Fig. 2, the guard plate is shown as forming one flange of a Z-shaped angle iron, the other flange 4, of which extends beneath the rail and from the bed plate therefor. In this case, the guard rail 4, is supported not only by the rivets 4X, which secure it to the angle irons 5, but by the downward pressure of the rail L, and the rail clamping means.

Where the anti-lifting guard rail is used in any of its forms, the wheel supporting structure or car, is also provided with an .extended portion O, which projects out beneath the guard rail 4, but is normally out of contact therewith. This extension O, prevents the car from rising and striking the elevated structure, or lifting of the wheels from the track.

The construction shown in Figs. 3 and 4, is of the saine character and purpose as those before described, with certain modifications however whereby the lateral guard plate 2, and the anti-lifting guard plate 4, are coinbined with an inside lateral guard iron 5, located just above the level of the rail tread and acting to prevent the rail from being forced to one side and so running oif the track. This construction we have shown in two forms. In Fig. 3, the plate 4, projects inwardly and is formed in one piece with a vertical longitudinally extending web 4, which extends upward to a point above the level of the rail tread, where it is bent inward as at 4. To this flange 4', is riveted one flange of an angle iron which forms the guard rail 6. 7, designates an adjusting bolt which connects the web of rail L, with the guard iron supporting plate 4. Nuts, 7, clamp the rail between them, and nuts and washers 7, engage on both sides of the web 4. lt will be seen that by this construction, the wheel is prevented from any lateral movement by the plate 6, that it is guided back onto the rail by the plate 2, and that the supporting car or wheel is prevented from lifting by the projection O, extending beneath the guard plate 4. ln Fig. 4, we show a like cornbination of elements as is shown in Fig. 3, the difference being that the guard iron or plate 4, is not formed in one piece with a web 4, which supports the guard iron 6. In Fig. 4, the guard iron is formed of an angle iron, one web 4, of which is riveted to an angle iron 5, as before described for Fig. 2, the guard rail being inturned and one flange extending up to the upper flange of the angle irons E. The guard rail 6', is independent of the angle iron 4, and is mounted upon the upper face of the angle iron E, and the bracket C. It has the form of an ordinary rail, the lower side of which is bent laterally to form a base 6X, which is bolted to the supporting structure. The guard rail 6, in Fig. 4, extends up above the tread of the rail L, and is held to the rail L, by the adjusting bolt 7, having the

nuts

7, 7, as before described. This adjusting bolt, as in the construction shown in Fig. 3, permits the guard rail to be drawn up tight in position, and to be adjusted properly with relation to the rail L, and the car wheel traveling thereon.

Incidental to the construction described we have shown in Figs. 1 and 2, the downwardly projecting outwardly inclined arm O, which is supported normally slightly above the rail L. rlhe purpose of this arm is to act as an auxiliary support in case the wheel axle should break. In this case the car would tall, but through the auxiliary' arm O, the car is supported upon the rails and without danger of falling even il the wheels should break.

Of course, we do not wish to limit ourselves to the precise construction shown, as the spirit of our invention may be embodied in many other forms without departing therefrom.

Having thus described our invention what we claim as new and desire to secure by Letters Patent is:
