My invention relates to railway frogs and particularly to'jump frogs for turnouts-for usewith continuous main track rails.

Heretofore it has been the practice, where @215 turnouts are provided for transferring a train from one track .to'anot'herto place a frog in the main track at the point where the tracks cross, or to provide a crossover which was adaptable :to be moved into and out of on contact with the main rail when it was desired to keep the rails of the, main track continuous so that there willbe no interference with the wheels of a train passing along the main track. V

In one case it was necessary for the flanges of the wheels of a train passing .al'ong'the main track to contact with the frog, therefore imparting jars to the cars and wear to the frog, and in the other case it was necessary 2:80 for asectionof the crossover to be moved into contact with the vmain rail each time the sw-itchzwas thrown to allow a train, to pass from the main track onto thesi'ding or to pass from the sidingon-tothc main track and then to be moved out of contact with the main rail so as to permit a train to pass .a-long'the main track. a i

It is therefore the object of, my invention toprovide ajump ztrog at the point Where 1 the turnout crosses the main rail which may he placed-into engagement with a main rail at any point along the main track without any alterations to the main rail and which will not interfere with the wheels of atra in passing over themain track.

Another ob ect t my invention is to'provide a jmnp frog which can belquickly moved from one location to another whenever-it is desired to change the'locationof the turnout.

Another object of my invention is torprovide the jump frog with an extension to which the adjoining rail may be fastened preferably without the use of fish plates.

The novel features of my invention will be more fully understood from the following description and claims taken with the drawings, in which:

Fig. 5;.is a cross section taken orf line 5 5 ofFig.2. y i i L Referring to the drawings more in detail,

10 and 11 designate the rails of a'ma in 'track which may be of anyconstruc'tion. Associated with the main rails 10 and ll are-gpivg oted switch points 13 and '14;, respectively, the switch point l3 'being constructed to abut the side of the raillO and theswitch {pointy to overlie the rail 11' when the switch is opera-ted to the position shown in Fi'gf 1 of the drawings. The end'o f the swit c'h point 14 is beveled so that the wfheel'o' f a train mayeasi'ly pass onto or off of theswitch. The switch points 13 and 14 are connected to: the turnout C rails 15 and 16, respectively. The'se'rails as well as rail 15a are 'supportedandheld in their proper spacedire'lation by means of the ties 17 The ties 17'are provided with chairs 18" upon which the ra ils'l5, 15o and lti -are placed so. as to elevate them Jt he'required amount. 7 The

rails

15 and 15a;are 'terminateda cient distance from the mainrai'l 11"to" allow my improved jump frog f20tohe inserted so asto provide means to p'er'mit'the wheels :of .a train on the turnoutto pass over the con 7 tinuous main rail. M I

improved jump frog 20] I comprises apair of membersZTandQZ which are adapted to engage. thef fishing surface-of the "main rail 11f. fThememiJe'rs 21 and 22am preferably provided with

integral extensions

23 and 24, respectively whichare adapted to preferably a.

engage the fishingsurface ofthe

rails

15 and 5 15a, respectively, and are provided with-apertures 25 :and 26, .respe' ctivelyfto receive suitable fastening means fOrcOnne'-tmg th'emto the rails 15 'and'15a. 1

A plate .27, which is operativelyattached to one of the members, preferahlyin-fixed "relation therewithfby any suitable fastenin' means such as rivets, bolts-"or welds, an which is provi'oled withmean's for receiving fasteners such as clips for clamping the other member thereto, is provided for the purpose of connecting these members in their proper relation to each other and with the main rail 11 when they are in their assembled condition. 3

The member 21 is provided with a tread portion 29 which is preferably in the same plane as the upper surface of the head of the turnout rail 15 when it is assembled there with, a rail engaging portion 30 which is adapted to engage the fishing surface of the rail 11 and a web portion 31 which connects the tread portion 29 and the portion 30 and also performs the function of spacing the portion 29 the required distance from the main rail so as to provide adequate clearance for the flanges, of the wheels of a train passing along the main rail 11. The web portion 31 lies a sufficient distance below the head of the rail 11 so as to provide adequate space so that the flanges of the wheels of a train passing along the main rail 11 will not come into contact therewith. The member 21 is also provided with outwardly disposed flanged portions 32, 33 and 34 which provide supports for the member 21 and also provide means with which fasteners, such as the clips 35, 36 and 37 may engage.

The clip is preferably of the adjustable cam type so that when it is turned on 1ts pivot 38 in one direction it will force the member 21 towards the rail 11 thus causing a gripping action of the members 21 and 22 with the rail 11.

The member 22 is provided with a portion 39 which is adapted to engage the fishing surface of the rail 11, a portion 40, and a tread portion 41 which is preferably in the rail 11 lies in approximately the same plane as the upper surface of the head of this rail. An upwardly extending guard flange 42, which is preferably integral with the portion 40, is provided as a guard for the wheels of a train passing over the member 22. Flanges 43 and 44 extend outwardly from the body of the member 22 and form supports for this member and also provide means for receiving fasteners, such as 45, for attaching the mem- -5 ber 22 to the plate 27.

From the above it will follow that the wheels of a train passing from the main track 10 onto the turnout, will pass along the rail 15 onto the portion 29 of the member 21 of the jump frog 20, which is in the same plane as the rail 15, until it is over the rail 11 whereupon the flange of the wheel will come into contact with the rail 11 and then the portion 40 of the member 22, which lies in the same plane as the tread of the main rail 11, until the tread of the wheel reaches the portion 41 whereupon the tread will engage this portion and then pass therealong onto the rail 15a which is in the same plane as the portion 41. The portion 41 is tapered towards the main rail 11 and the portion 40 is tapered in the opposite direction so that the wheels will pass onto the portion 41 without shock.

While I have shown my invention in but one form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various other changes and modifications without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are imposed by the prior art or as are specifically set forth in the appended claims.
