RAILROAD-CROSSOVER.

Specification of Letters Patent.

Patented June 28, 1921.

1 0 all whom it may concern:

Be liEkIlOWIl that I, JAMns B. STRONG, a

I citizen of the United States, and resident of vwheel engaging members for assisting the flanged wheels of the railway vehicle past the crossover and which, due to their function of protecting the flanges of the wheels,

will be referred to hereinafter by their commercial name of flange guards and easer joints.

In one standard form of such cross-overs the flange guards are formed integrally with the solid frog and this form'of construction is giving satisfactory service and is econom- 1cal equipment especially where traffic 1s li ht I I It 'Wlll be understood, however, that in direction with a resultingwear only on one of the flange guards and frequently the en tire frog must be scrapped when a part becomes worn.

One of-the objects of the invention is to provide a frog construction which will possess all of the advantages such as rigidness of construction inherent in these standard, solid, one-piece frogs but which at the same time will feature economy in use under heavy traiiic conditions in that it will permit the ready replacement of the part or parts which are subjected to severe'wear without the ne cessity of scrapping the entire frog when the worn part becomes inoperative.

Broadly I attain this object bv forming a flange guard and the teaser joint in onepiece and demountably securing the same to one or both sides of the main part of i the solid standard form of frog, by some ap proved form of locking means.

Another object of the invention is to provide a frog the ends of which are constructed to receive the contiguous ends of the usual service rails without the necessity of any squared off ends of the service rails and securing the service rails rigidly in position engaging the frog by means of the separable flanged guard at one end of the frog, or, as an alternative construction by means of the usual angle bars at the opposite end of the frog.

The invention contemplates the utilization of fastening means for demountably securing the flange guard to the frog and service rails in a manner to eliminate rattle and to secure solidity in the construction and an easy ride to the vehicle as the wheels pass across the frog.

I attain this phase of the invention most conveniently by extending laterally from the frog a base plate which may be integral with the frog or a separate plate secured to the frog and which in turn supports fastening means preferably in the form of wedge clip tie plates for securing the flange guard in tight bearing engagement with the frog and with the contiguous ends of the service rails.

Various other objects and advantages of the invention will be in part obvious from an inspection of the accompanying drawings and in part will be'more fully set forth in the following particular description of one form ofmechanism embodying my inven tion and the invention also consists in certain new and novel features of construction and combination. of parts hereinafter set forth and claimed.

In the accompanying drawings Figure 1 is a plan view of a frog' construction illustrating a preferred embodiment of the invention; and

Figs. 2', 3 and 4 are each transverse sectional views taken respectively on the lines 22, 3 3 and 4.-4 of Fig. 1.

In the drawings, there are shown the usual supporting ties at the crossover, positioned on which is the frog 10, fitted between the service rails, as is usual in such constructions". The frog is of a one-piece solid construction and includes a base plate 11 relativelywide at one point indicated at 12 to form a tie engaging support 13 and reducing in width toward opposite ends. Wheel rim engaging members project upwardly from the base plate, two of which members are transversely spaced apart and are slightly curved from the wide portion 12 toward the toe end of the frog to form frog rails 14 and 15 The third rim engaging surface is in e the form of a long triangle in plan, and extends from adjacent the heel end of the frog to a point mid-way of the length of the frog rails to form the usual point 16. It is understood of course that the frog is recessed between opposite sides of the point and between the frog rails to form the usual flange receiving grooves 17. The character of the construction as thus far described is drawn substantially along known lines and V novelty is not predicated upon this construction per se.

The heel end of the frog is provided centrally thereof with a longitudinal extension 19 whi h provides a transverse abutment for receiving the inner sides of service rails 19 and 20 shown in dotted outline. The usual angle tie plates 21 alsosho-wn in outline lap the sides of the broad end of the point and the service rails and arev fastened thereto by the usual through bolts 22. The parts are so proportioned that the tread surface of the service rails is continuous with the tread surfa e of the point as is usual in such constructions.

The toe ends of the frog rails are squared off, as shown at 23, against which abut'the squared off ends of the opposite service rails 24 and 25. The base plate 11 at this toe end of-the frog is extended longitudinally to receive the service rails as shown more particularly in Fig. 2 and the rails are maintained in their transversely spaced apart relation by a filler block 26 which may )6 fastened to the base plate 11 by means of the rivet structure 27, as shown in Fig. 2. It is obviously within the scope of the invention, however, to form the filler block 26 integrally with the base plate but'the illustrated form is preferable under certain circumstances for commercial reasons. The outer side of each of the frog rails simulate to some extent the outer side of the I-beam type of rail to provide a guard engaging face 28.

This face is engaged by a relatively long point, past the point and beyond the toe ends 23 of the frog rail. The guard 29 is provided with an inclined wedgeshaped top surface 29 for receiving the wheel rim and has .an u tistandlng guard flange 14 and 15 at'its outer edge for engaging the side of the wheel rim.

The projected portions of the flange guard are secured together and to the service rails 24 and 25 by means of through bolts 80 one 1 of which passes through thefiller block 26;

The frog is provided with longitudinally spaeed-apa-rt'sleeves formed integral therewith and through bolts 31 are passed through the flange guards on opposite sides and through the sleeves, The bottom plate 11 is extended on opposite sides to form a series of fastening plates 82 disposed to rest on the ties and fastened thereby by spikes passed through the spike holes 33.

At the left of the showing in Fig. 1 is shown a slightly modified form in which the plate 34 is separate from the frog.

The plates 32 and 3e are provided at opposite ends with upstanding shoulders 35 be tween which and the adjacent edge 36 of the flange guard is positioned a wedge clip 3'? secured in position by fastening bolts 38 as is well known in such securing structures.

Having described my invention, I claim:
