Specification of- Letters Patent. i Patented Aug. 30, 1910.

Application led April 19, 1910. Serial No. 556,417.

To all whom it may concern: e v

Be it known that I, RICHARD P. DELA.- NEY, citizen of the United States, residing at Fairchance, in the county` of Fayette and State of Pennsylvania, have invented certain new and useful Improvements in Guarded Frogs, of which the following is a e The invention consists in the provision of'. guard rails whlch are located on each side .of thecrossing and main rail and extend parallel thereto opposite to the switch point and alsoin the provision of an interior guard rail mounted between the converging crossing rail and main track rail.

My invention is shown in the accompanying drawings, wherein: y

Figure 1 isa plan view of my improved guarded frog; and Fig. 2 is -a sect-ion on the line 2--2 of Fig. l.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters;

Referring to these figures, A-A-A2 designate the` main rails of a line of track and B-B-B2 ay line of rails extending lacross the main rails. A-,AA2 and B-B-B2 are 0f any ordinary construction and areof the usual or standard form in cross section, as shown in l Fig. 2. The rail B is bent at its extremity,

as at 2, while the rail A is likewise bentat its extremity, as at' 3. The rail A2 extends, of course, in alinement with the rail A and converges toward and meets the rail B2 of the cross track, the two rails being cut away at their meeting points, as at C to form the point of the frog. The main guard rails are designated 4, 6, 14 and 15 and may be madel either of T-ra'ils of the ordinary or standard form, such as shown in Fig. 2, 0r of a solid casting. The guard rail 4 extends parallel to the rail B and is angularly bent at its middle, as at 5, the ortion 4 'of the guard rail extending paral el to the rail A2. The

yand B2.

These rails guard rail 6 is also bent at its' middle, as at\ 7, one portion of the guard rail extending parallel to the rail A-while the other p0rtion 6 extends parallel ,to the rail B2. The i guard rails 4 and 6 lare separated or spaced from the rails A and B and rails .A2 and B2 b'y means of separating blocks 8, 9, 10 and 11.

. The separating blocks 8 and4 9 are of less length than the distance between the ends of the rails 4 and 6 and the point at which these rails are bent, and are held to the gua-rd rails and tothe cross and main rails of the track by means of bolts 16 which pass t rough the separating blocks and are provid d with nuts on the opposite ends thereof. rlhe p0rtions 4 and 6 ofthe gua-rd rails are also separated from the rails B2 and A2 by means of the separating blocks previously referred to, of like character to the separating blocks 8 and 9 and through these blocks and. rails pass the bolts 16.

Mounted between the rails A2 and B2 at the junction thereof are the guard rails 14 and 15, these rails converging and beingcut away at their meeting points so that both rails 14 and 15 are parallel to the rails A2 The guard rails 14. and 15 are likewise separated from thetrack rails A2-and B2 by means of separating blocks 12 and 13.' The bolts 1G used in this portion of thc frog pass tliropgli the rails 6", the separating blocks, the track rail B2 andl the! separating blocks 14, so that the guard rails 14 and 15 and the main and side rails are all held in solid engagement with each other. The bolts also pass through the guard rail'4,

separating blocks 10, the main rail A2, the

lation with each other and that bo'th interior and exterior guard rails are provided, these guard railsl being extended` higher than the standard -rails forming the main track and cross track, as shown in Fig. 2.

My improved guarded frog may be formed of T-rails or of a solid steel casting.

It is to be observed that the points 5 and 7 where the guard rails 6 and 4 are bent, are placed beyond the point C and that -the portions 2 and 3 of the` rails A and B are in alinement with the portions 4 and 6 of the guard rails 4 and 6. Thus the car wheel is guided by the guard rail until its 'ange has passed over the point C no matter in which direction the car is moved, and that it is impossible for the wheel by any means to move from the main rail to the cross rail or from thecross rail to the main rail.

It yis particularly to be noted that the wheel is guided in the proper position to pass the point C by reason ofvits rim engaging with the guard rail and that the flange of the wheel is not guided. Thus there is no danger of breaking the-flange, and, furthermore, there is no danger of the wheel'being misguided 'by reason 'of a broken flange. As soon as the wheel passes the beginning of one of the guard rails, it is held in such position that the flange will not ride up or the wheel be directed upon the wrong track.

One of the advantages of my guarding frog is that the space between the main rail and the guard rail can be filled so that the foot of a walker need not be caught between the guard rail and themain rail, as very often happens with the -ordinary frog. Furthermore my improved frog does away with the second guard rail .on -theopposite side of 'the ltrack jfrom the frog, and inas much as it is limpossible for the wheel to get off the track at the point of theirogl itk is particularly good for mine use, as the minecar wheel is loose on the( axle and the guarded frog is protected at this point. Having thus described the invention, what is claimedas new is: i

1. A rallway frog comprising spaced main Y rails, spaced crossing rails extending at an angle to the main rails, an angular guard rail extending parallel to one ot the main rails and then extending parallel to one of t-he cross rails in spaced relation thereto, an op# positely disposed guard rail extending parcrossing rail and then parallel to the 'other main rail, converging guard rails disposed between one of the maid! rails and the adjacent crossing rail, Yand means for rigidly holding said guard rails l and track rails in spaced relation to each other. l

2. A railway main track rails, spaced crossing track rails at an angle to the main rails, an angular guard rail extending parallel to one of the main rails and then extending parallel tol one ofthe crossing rails, an oppositely disposed guard rail extending parallel to the other crossing rail and then parallel to the other main rail,'converging guard rails disposed between one oflthe main track rails and the adjacent crossing rail, and'separating Ablocks disposed between the track rails and the guard rails, and bolts passing through the track rails, guard rails and said spacing blocks.

3. A railway frog, comprising a main rail in two sections spaced from each other, the end of one of said sections being Haired, a crossing rail also in two sections, and the end ofk one of said sections being outwardly end of lthe ection of the main rail, angular guardrail lextending along parallel to correspondin sections ofthe main and crossing rails and/v` engaging with the outwardly turned ends of the sections of the main and -crossing rails and then extending parallel to the opposite sections of the main and crossing rails, spacing blocks located between the said guard rails and the said track rails, converging guard rails disposed bef tween one of the sections ofthe main rail vand theadjacent section of the crossing rail, spaced blocks located between said converging guard rails and the means for holding said track rails, guard rails and spacing blocks in rigid relation to each other.
