T0 ALL WI-IOM IT MAY CONCERN:

Be it known that I, WILLIAM WHARTON, Jr., of Philadelphia, Pennsylvania, have invented an Improvement in Railroad Frogs; and I do hereb'y declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing, and to the letters ot'- rei'erence marked thereon.

My invention relates to an improvement in the railroad-frog'for which Letters Patent were-granted to me on the 18th of July, 1865, and my improvement consists in the manner,` substantially as described hereafter, of securing, by bolts or oth'er equivalent fastenings, the main railto the frog, so that the former can be removed In order to enable others skilled in the art to make and use' my invention, I will now proceed to describe its construction and operation. 4On reference to the accompanying drawing, which forms a. partof this speciication Figure 1 represents my improved frog with adjacent rails.

Figure 2, a transverse section on the line 1-2, iig. 1.

Figures 3 and 4, modifications of the frog.

Figure .5, a transverse section on the line 34, iig. 4; and

Figure 6, another modification ot' the frog. v On reference to iig. 1, A and A represent the rails of the main track, and B -and B ithose of the'turn-out,

D being thc`frog, situated at the crossing of the rails A and B. This 'frog is asubstantial casting, made, in the presen-t instance, of-one piece, and secured to the track by bolts or spikes passing through lugs aa. It will be observed that the continuity of the rail B of the turn-out is interrupted for the reception of the frog, while Vthe latter has a recess, 6, for the reception of the rail A of the main tracl, so that the continuity of the latter is uninterrupted. In these respects the frogis similar to that described in my patent of July 18, 1865, in which frog, however, Vthe rail fit-ted so closely and tightly to the recess of thc frog that its removal was a. matter of diieulty. In the present improvement, the recess b is at its narrowcst point considerably wider than` the rail,

to which one side only of' thc said recess is adapted, as best observed on reference to fig. 2, the rail being secured to that side of the recess adapted to by bolts e. On removing the nuts of these bolts, therrail can be moved laterally, and after this, readily withdrawn longitudinally. The rail B of thc turn'out is elevated above the level of the rail A of the main track, the rib dof the frog, where itA meets the said rail, having a correspondingV elevation, so that the flanges of the car-wheels, as they traverse the turn-out in the direction of ,the arrow -and across the frog, may be elevated above the main rail A', as described in my aforesaid patent.

In Iig. 3, thefrog is similar to that illustrated in fig. I,V with the exception that in the former figure a portion, y, of the frog forms a,part of the main rail Ascand renders the same continuous.

In the modification illustrated in figs. fnd 5, the frog is made of two parts bolted together, so as to embrace and confine the main rail in a manner which will bc readily understoodv without description.

i In the modification, fig. 6, the frog is also in two parts bolted together, so as to confine the rail. In this cpse, however, a portion, g/,ofi one part of the frog forms a continuation of the said main rail.

I claim as my invention, and desire to secure by Letters Patent, as an improvement in the frog described in my patent of July 18, 1865- The frog I), having a shoulder against which the side of the main rail bears, and to which it is confined by bolts e, or their equivalents, substantially as and for the purpose described. l V

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.

WM. WHARTON, JR.
