RERAILING FROG.

Application filed June 19, 1924. Serial No. 721,028.

To all whom it may concern:

Be it known that I, HENRY D. SHIVELY, a citizen of the United States, residing at Trenton, in the county of Grundy and State of Missouri, have invented certain new and useful Improvements in Rerailing Frogs, of which the following is a specification.

My invention relates to railroad appliances and the object of the invention is to provide a portable frog for replacing cars after they have become derailed.

The invention relates more particularly to rerailers which rest upon the balls of the rails and the cross ties and has laterally extending wing plates to guide the wheels of a car back upon said rails;

Another object is to provide devices of this character which will guide the wheels upon the. rails and not allow them to cross over the balls of said rails and again'become derailed during the rerailing operation. Z

A further object is'to provide devices of this character which are so formed that after one set of wheels of a four or six wheel truck have been replaced on the rails, the following wheels can pass over the rerailers without danger of being derailed thereby and without undue jar or shock.

lVith the above and other objects in View, which will hereinafter appear, reference will now be had to the accompanying drawing, in which:

Fig. 1 is a plan View of a pair of rerailers in position on a railway track.

Fig. 2 is an end elevation'of the parts disclosed by Fig. 1, excepting that the rails are in cross section.

Fig. 3 is a side elevation of one of the rerailers in position on a rail, the ties being in cross section.

Fig. 4 is a longitudinal section of one of the rerailers on line IVIV of Fig. 1.

Fig. 5 is a cross section of one ofthe rerailers taken on line VV of Fig. 1.

As the two frogs which constitute a pair differ only by having several elements in reverse order to each other, a description of one will sulfice for both.

The frog comprises a body portion embodying alongitudinal rib 2 and wing plates 4 and 6 extending laterally from opposite sides of said rib 2.

The rib 2 is adapted to fit over and rest upon one of the rails A of the track and,

descend said rib without undue jar.

tapers at its rear and forward'portions as indicated at 8 and 10, respectively, so that the tread of a car wheel may ascend and The rear end 11 of the rib 2 projects rearwardly of the wings 4 and 6 to coact with the taper 8 in providing an easy gradient for the wheel to ascend. A' longitudinal offset 12 is formed in one side of the rib 2, paralleling the inner surface B of the ball of the rail A, the top 14 of said offset sloping downwardly at its rear and forward ends 16 and 18, respectively, below the top of the ball of the rail, Figs. 2 and 3, so that the flange of a wheel may travel over said top 14 without touching the same, or in the event that it did touch the ascentand descent would be accomplished without 1211- due jar or shock.

15 and 17 which rest upon two of the ties upwardly from their rear ends 20 and 22 to their forward ends 24and 26,'as best shown v by Figs. 2, 3 and 5, and are-provided at their forwardly converging margins with flanges 27 and '28, respectively. The- wing plates 4 and 6 also slope downwardly from their flanges 27 and 28, respectively, to the adjacent longitudinal sides of the rib 2, as best shown by Figs. 2 and 5, providing oppositely-disposed channels 29 and 30 for guiding the rails A.

The base of the wing plate 6 is provided at its forward portion with a lug 32 having holes through which spikes D may be driven into the underlying tie C to coact with similar spikes driven through holes in the rear portions of the wings 4 and 6 in firmly holdmg the frog in proper relation to the associate rail A. Spurs 31 and 33 are also provided at the rear portions of the wings 4 and 6, respectively, which become embedded in the underlying tie and assist the spikes D in holding the frog in place. I

The wing 6 extends forwardly of the rib 2 as best shown by Fig. 1 and rests upon the ball of the rail A to constitute a guide 34' The wing plates 4 and 6 have flatbases derailed wheels upon the Figs. 1 and 2, so that if the wheels of a car are derailed at the right side of the re spective rails A, said wheels will, as the car moves forward, enter the flaring entrance of the channels 29 of the left frog and the channel 30 of the rig-ht frog, and be guided by the respective flanges 27 and 28 of the rails A. As the wheel at the left travels up the channel 29 it is prevented from crossing over the associate rail A and again becoming derailed by the guide 34; against the margin 86 of which and the inner surface B of said rail A the flange of the wheel contacts, thereby guiding said wheel upon the rail as it runs off the forward end 24 of the wing l, which being shorter than the wing 6 permits the wheel flange to drop and engage the margins 36 of the guide 34 and the inner surface B of the rail A, as above stated. As the frogs guide the forward wheels of a car truck upon the track the following wheels, which may not have been derailed, are free to travel over the frogs 2 without undue shock owing .to the tapered ends 8 and 10 which permit the tread of the wheels to readily ascend and descend the rib 2, while the flanges pass over the offsets 12, thereby not only avoiding shock as above stated, but also all possibility of said following wheels becoming derailed as they pass over the frogs.

Should the wheels be derailed at the left side of the respective rails the wheel at the left will pass up the channel 30 of the left frog and the channel 29 0f the right frog and be directed by the guide 3a of the latter frog and the inner surface of the ball of the associate rail, back upon the track.

Should the wheels of the car truck be derailed astride the respective rails they will be guided upon the track by the respective frogs.

From the foregoing description it will be understood that I have provided rerailing devices embodying the advantages above pointed out, and while I have shown and described the preferred embodiment of the invention I reserve the right to make such changes in the construction, combination and arrangement of parts as properly fall within the spirit and scope of the invention as claimed.

Having thus described my invention what I claim and desire to secure by Letters Patent, is:

In a car replacer a longitudinal rib adapted to fit over a rail, forwardly ,diverg ing wing plates extending from opposite sides of said rib and sloping upwardly towards their forward ends and longitudinal margins, a guide at the forward end of one of said wings which rests upon the ball of the rail and has one margin flush with the inner margin of said ball, and flanges sloping upwardly and forwardly from the margins of said wing plates and one of which extends to the forward end of and reinforces said guide while the other terminates in a line with the rear end of said guide.

In testimony whereof I affix my signature.

HENRY D. SHIVELY.
