ltailway-Frogs, of which the 'ollowing is a specification.

.\l invention relates to railway t'rogs cast. or nnule in one piece, and has for its ohject such :rtlesign and arrangement of the parts as will provide a fixed and positive connection ht-tween the rails and frog proper remove the-shock occasioned hy the wheels when passing over the joints where the rails join the 'lrog, p event the flanges of the wheels from cutting, hitting, or riding the point of the frog; also to provide a proper means for electrically connecting or honding the frog into the general track 'systetn, all of which is more fully descrihed and claimed.

By reference to the drawings forming a part of this specification, Figure 1 is a top view or planet my improved frog, Fig. 2 is a section of the same on the line lI-TI in Fig. 1. Figs. 3,4. and .3, are seetionsoirthe tines llllll, 1V-1V, and V-V, respectively in Fig. 2, looking in the direction of the arrow, Fig. 6 is an end view of one half of the frog looking in the'same direction,

and it'will he noted that in addition to the point 1, and heels 2, there are the fish plates El, 3, 3. made int gral with the frog proper; these fish plate are further reinforced hy the flanges l, 4, and vertical projections .7, .7, which project alongthe side of the top flange of the rail. high enough to 'otl'er a support to thd wheels passing over the rail. n such a manneuthat at the time the wheels pass. the joints 6; 3, they will be entirely supported thereon and prevented from pounding as they would otherwise.

Inasmuch asthetread of the wheels rapidly heroine grooved. due to the constant friction upon the rail, thus forming a projection or flange on the outer side of the mint 1 or take the course on'the wrong side ever. thistendency is overcome as tnat part of the tread which hes beyond the rail and forms the secondary flange ahove alluded to,

rail from the, flange proper. there Is always a tendcncygor of the point. In my i'in n'oved fr g. how

rides up over the heel on the'vertical pro-- jeetion 5, thus causing the wheel to trail naturally along its proper path. The projections 5, may he cut away, forming inclined surfaces 12-12, so that. this transference of weight from rail'to lish plate and irog takes placegradually, thus preventing all shocks that oc ur when two rails or incinhers meet as in the ordinary way. The sectionot' the fish plates 3, I and the fact that they are integral with the "frog, gi\'t-..t-ltein sutiicient strength and rigidity to inalie the curve thus insuring the proper approach and departure to and from the frog. A tlange or base 7 isprovided w ith a hole '8 into which the honding wires can he attached. It referred to have the web 11 which attac res the point to the heels just. low enoi'igh to allow the flanges of the wheels to pass "there through, and it may he high enough to act as a support to the wheels through the flanges, in whichcase it is preferahle to have inclined approaches 10', 10, thereto; for in this construction the total strength of the frog may he made the greatest with the least .wei'ght of material; it also prevents dirt from accumulating there, or anyones foot from getting accidentally caught therein.

\Vhile I have described with particularity one form of frog, carrying out my invention it will l )e'readily seen some ot 'the advantages thereof could he ohtai'nerl by making thc'same in two or more pieces, by changing the form, and in other ways so, I do not conthe tornrsh wn.

I claim as my invention is as follows; 1. A railway track structure ha ring atone detaclnihly secured, and which fit the said and constitute the only means of ltee ling the rails in alineinent with the parts of tlletltifik structure with which the railsare supposed to register. t o

railway tltlt'h structure having at one end two arms against which two rails are detachahly secured and; which fit the said rails between their topand hottoin flanges and having a projection extendingup along the side of the head of the-rail to the top thereof, the said arms constituting the only 'means of keeping the rails in alinement with the oartsof the track structure with which the rails are supposed to register.

rails, when holted thereto, assume the proper Having described ray improvedlrog what end two arms against which two rails are" fine myself as regards my hroader claims to rails hctwet-n their top and bottom flanges endtwoarms. against'whi ch two rails are 3. A railway track structure having at one det'achably secured and which fit the said rails between the top and bottom flanges and have a projection extending up along the side of the head of the rail to the top thereof, the said. projection being provided with inclined surfaces adapted to gradually receive the Weight of the wheels traveling, thereover',

the sa'idarni'si forming the only means of keepingthe rails in alinement with the parts of the track structurewith which the rails are supposed to register.

' 4. A'railway track structure having at one end two arms one side of each being parallel to the path of the Wheels passing thereover and which fit the rails between the top .and

bottom flanges on one side of therail only in such a manner that when the rail is secured against the arms the operative side of the head of the rail shall be in approximate alinement with an operative side of the track "structure, the said arms forming the only means "of attaching the rails to the track structure, substantially as set forth.

5. A railway track structure having at one end two arms one side of each being parallel toLthe path of the wheels passing thereover v and which fit the rails between the top and bottom flanges on one side of the rail only in such a manner that when the railis secured a ainst thearms, the operative sideof the head of" the rail shall be in up roximate' such a manner tha alinement with an operative side of the track structure, the said arms being provided with a projection extending up along the side of the head of the rail. to the top thereof the said arms forming the only means of attaching the rails to the track structure, substantially as set forth.

6. A railway track structure having at one end two arms-one side of each'being-parallel to the path of the wheels passing thereover and Which'fit the rails I bottom flanges on one side of the rail only in between the top and ,agalnst the arms, the operative side of the head of the rail shall be in approximate ahnement with the operative side of the track structure, the said arms being provided with 1 a projection extending up along the side of the head of the rail to 'the top thereof, top 7 surface being inclined toward tllGSlllllCtltt'G of which it forms a part, sul'istantially'" as set forth.

7. A railway track structure having at one end two arms which rest on the top of the bottom flange of the rails and extend up along the side of the top flange of said rails approximately to the top thereof andhaving their top surfaces inclined toward the body of the structure, substantially as set forth.

' 8. A railway-track structure having'a heel rail wider than the head of the rail to which it attaches and provided with an inclined surface adapted. to gradually receive the load from that portion of the wheel tread which extends .over the outside of the rail head, substantiallyas set forth.

9. A railway track structure having a heel rail Wider than the rail head to which it attaches and provided with an arm alongthe outside of the said rail, the said arm fitting the said rail between the top and bottom flanges and extending up along the side of the head of the rail to the top thereof, the said arm forming the sole means-of con-- necting the heel rail to the rail with which it coiiperates', substantially as set forth.

10. A. frog heelrail' having atone end an arm which rests on the top of the bottom t when the rail is secured P. Gr. ELDER.
