Specification of Letters Patent.

Application filed August 28, 1920. Serial No. 406,606.

over of the built-up type which is provided on opposite sides with wheel tread engaging members for assisting the flanged wheels of the railroad vehicle past the cross-over and which due to their function of'protecting the flanges of the Wheels, willbe referred to hereinafter by their commercial name of flange guards and easer joints. .The present application constitutes a companion case with a similar application filed under even date and having Serial No. 406,605.

In the companion application there was featured a solid frog construction in which a combined flange guard and easerjoint were formed in one piece and demountably se cured on opposite sides of the main part of the solid frog structure and in which the solid frog constructionalso formed a base support forthe combined flange guard and easer joint.

The present disclosure constitutes, 1n effect, a modification of the showing in the above identified application in that the demountable flange guard featured in the prior application is assembled with a built-up frog of some conventional form to provide a simple and readily formed type of fiange guarded cross-over which will perm t the ready replacement of worn parts without the necessity of scrapping either the entire frog or any unworn parts thereof.

Another object of the invention is to provide a frog construction of the type outlined, the parts of which can be made up from standard parts and slightly modified in situ, if necessary, to form any particular character or size of frog desired in any particular location. 7

Still another object of the invention is to provide a simplified tying means for securingthe assembled parts of the frog construction in fixed position relative to each other and at the same time to secure the flange guards in set position and yet in pos1t1on so that they may be readily replaced.

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

In the accompanying drawings:

F1gure 1 is a plan view of a frog construction illustrating a preferred embodiment of the invention and Figs. 2 and 3 are each transverse sectional views taken. respectively on the lines 2-2 and 3-3 of Fig. 1 looking in the direction indicated by the arrows.

Patented June 28, 1921.

In the following description and in the claims, parts will be identified by specific names for convenience of expression but they are intended to be as generic in their application to similar parts as the art will perm1t.

In the drawings, there are shown the usual supporting ties at the crossover positioned on which is a built-up frog construction which is of more or less conventional form and which has been selected to show the application of the replaceable guards to a conventional structure. In Fig. -1 there is shown a pair of service rails 10 and 11 disposed at an angle to each other and with their adjacent ends cut to a bevel and connected to form the frog point 12. Another pair of rails 13 and 14 are disposed for their main length at an angle to each other and designed to form continuations respectively of the rails 11 and 10 across the joint. The service rails 13 and 14 are extended past the point 12 on opposite sides thereof and have their end portions bent outwardly to form flared ends and are spaced apart by filler blocks 20. The point 12 is held in position midway between the portions of the rails 13 and 14: within the outlines of the frog and identified hereinafter as wing rails, by

wedge filler blocks 21 and 22 disposed on opposite sides of the point. Certain of the parts are held together by through bolts 23 and it is to be understood in general that the construction as thus far described is of conventional form.

The organization of parts so far recited to form the frog is mounted upon one or more base plates 24-, which in Fig. 1 are shown to be three in number, and positioned on adj acent ties. The base'plates are of wide, practically flat steel plates, are ofsimilar form and extend'transversely of the length of the frog. The base plates are provided at opposite ends with upstanding shoulders 25 con stituting projections preferably formed integral with the plates, disposed in spaced relation to the wing rails, and positioned-on opposite sides thereof as shown in Fig. 2. A pair of preformed castings 26 each constituting a combined flange guard and easer joint are positioned on oppositesides of the frog construction and lap the'point 12 as shown more particularly in Fig. 1. The wheel rim engaging portion 27 of the member :26 is widened toward the "heel end of the same to provide a broad surface 27' which overlaps the rail at this point and constitutes a tread guard.

The flange guard'26 is provided on its inner side with an upstanding member 29 shaped to fit snugly against the adjacent face of the wing rail and rests at its lower end upon the upper face of the lower outer flange 30 of the engaged wing rail. The guard also includes an outwardly extending bottom flange 31 with the lower face 32 designed to be disposed in the common plane which contains the lower faces of the several surface rails so as to provide a broad bearing surface for engaging the base plate 2a or other support for the construction. Long through bolts 33 are passed through the service rails,through'the interspacing filler blocks and through one or both of the flange guards so as to securely fasten the several parts rigidly in position and yet to fasten the parts so that they may be readily demounted for replacement or repair.

Supplementing this means for connecting the parts together additional means are illustrated for locking the combined frog construction with its guard rails to the base plate 32. For this purpose wedges 34; are driven between the projecting shoulder 25 on one side and theadjacent flange 31 which wedges are locked to the base plate by bolt and slot connections 35 provided with lock nuts 36. It is obviously within the scope of the invention to duplicate the wedge on opposite sides of theconstruction.

In order to more effectively lock the parts in position in the situation where at least two base plates are used the construction of the lower flange of the guards illustrated in Fig. 1 is suggested. In this showing theouter edge 41 of one of the flanges 31 is inclined inwardly to form converging sides 37 and the flange engaging edges 38 of the wedges are cut at an angle to the length of the. slot in the slotted construction 35 to engage the inwardly and centrally directed edge 37 in such a. manner that moving the wedges away from each other and longitudinally of the length of the construction on each side will tend in their effort to move the guard in opposite directions to press the tion free of any looseness of parts and capable of withstanding strains to which such devices are subjected in a mannerwhich has proven entirely satisfactory in practical operation. I

It is usually true that due to the fact that traflic is heavier in one direction than the other over any particular oint, one of the guard rails will wear away more rapidly than the other. In order to replace any such worn rail in the device disclosed it is simply necessary to remove the holding bolts,loosen the wedges, remove the worn rail and replace the'same with a new guard and this replacement can be'eflected practically without changing any of the parts of the builtup frog construction and even without removing the through bolts from their position. It is possible with the construction disclosed to make changes in the relative arrangement of the service rails, simply by shifting the wedging filler blocks or replacing the same with other filler blocks of a different size and this can be effected while using a standard form of combined flange guard and, ease'r joint. Not only can the flange guard be replaced when worn without affecting the present position of the frog but the service rails may likewise be re placed simply by loosening the wedges and withdrawing the through bolts, inserting the new rail in position and tightening upthe wedges and bolt carrying means.

no material interruptionisnecessary to the service across the frog. V 1

In those situations where the wedge plates are confined to one side of the structure as shown in Fig. 1, the flange 31 is provided with extensions 39 which engage against the adjacent shoulders 25 and are secured to the base plate by bolts 40.

While I have shown and described, and have pointed out in the annexed claims, certain novel features of my invention, it will be understood thatvarious omissions, substitutions and changes in the form and details of the device illustrated and in its op oration maybe made by those skilled in the art without departing from the spirit of the invention.
