To all whom it may com-em:

Be it known that 1, ANTHONY L. Visser, a citizen of the `United States of America, residing at Bridgeville, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Railway-Frogs, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to railway frogs and more particularly to that type disclosed in my prior Patents No. 912,049 granted February 9th, 1909 and No. 940,560 granted November 16th, 1909.

The primary object of my invention is to provide a frog with a movable block for controlling the passage over rails'converging at the frog, the movable block being constructed to provide a strong and durable structure that insures a safe passage of heavy rolling stock over the frog.

Another object of this invention is to provide a movable frog block that can be shifted simultaneously with a switch mechanism, including a signal, the frog block being arranged whereby it can not become accidentally displaced during the passage of rolling stock over the same.

A further object of this invention is to provide a frog block that can be repeatedly adjusted to compensate for wear.

With the above and other objects in view, the invention resides in the novel construc tion, combination and arrangement of parts to be hereinafter specilically described and then claimed.

Reference will now be had to the draw ing, wherein like numerals of reference designate corresponding parts throughout the several views, in which:

Figure 1 is a plan of a frog in accordance with this invention; Fig. 2 is a longitudinal sectional view of the same; Fig. 3 is a perspective view of a bed plate; Fig. 4 is a perspective view of a detached guide strap adapted to form part of the frog; Fig. 5 is a perspective view of a detached brace or guard adapted to form part of the frog; Fig. 6 is a plan of a modified form of frog block; Fig. 7 is a plan of hinged gates to facilitate removing dirt from the bed plate; Fig. 8 is a longitudinal sectional view of the same; Fig. 9 is a perspective view of an attached gate; Fig. 10 is a perspective view of a keeper used in connection with the gate;

and Fig. 11 is a perspective view of a detached stop.

The reference numerals 1 and 2 denote cross ties adapted to support a bed plate 3, which is rectangular in plan. r1`his bed plate has the ends thereof provided with slots or openings 4 and 5 for the confronting ends of rails G and 7. The rails are supported by bottom plates 8 riveted to the bed plate 3, and the ties 2 are cut away, as atl 9, to`provide clearance for the bottom plates 8.

The rails 7 are spaced apart by a block 11 arranged between the rails 7 and secured thereto by tie bolts 12 and nuts 13. The cuter sides of the rails 7 are braced by bars 14 bolted or otherwise connected, as at 15, to the bed pla te 3, the bolts having the heads thereof eountersunk in the bars 14. Each bar has a depending tongue 1G extending from one end thereof to the opposite end, and this tongue is adapted to fit between the outer base fianges of the rails 7 and the lon gitudinal edges 17 of the seat 5. The rails 8 are held by similar bars 18 bolted or otherwise connected to the bed plate 3, as at 19.

The bed plate 3, intermediate the ends thereof, is provided with sets of transversely arranged slots 20 and 21, the set of slots 20 being located centrally of the bed plate, while the slots 21 are at the outer edges of the bed plate with the outer edges of the slots open. The slots 21 are adapted to receive the vertical portions 22 of guide straps 23 bolted or otherwise connected to the bed plate, as at 24, said bolts extending through openings 25 provided thereforl in the straps 23. The straps 23 have guides 26 for the rectangular ends of bars 27 mounted in a frog plate 28. Those portions of the bars 27 within the frog 28 are dove-tailed, as at 29 and the dove-tailed portions are fixed within the block by screw bolts or other fastening means 30 extending downwardly through the block. This manner of connecting the frog block 28 to the bars 27 prevents said bloclr from becoming accidentally displaced relatively to said bars.

The frog block 28 has straight passages or grooves 31, adjacent to the longitudinal edges thereof, and a diagonally disposed passage or groove 32 between the passages or grooves 31. One of the grooves 31 and the groove 32 coperate in controlling the passage of rolling stock from the rails 6 to the rails 7 and after the side walls of these grooves have been worn, the block 28 can be reversed whereby the other groove 3l will cooperate with the groove 32. The frog block Q8 is provided with depending lugs or pins 33 extending' into the slots 20, these lugs limiting the movement of the frog block upon the bed plat-e. To protect the slots 9,0 and prevent foreign mat-ter, as coai dust, from accumulating in saidl slots, a cover plate is bolted or otherwise secured, as at 35, to the under side of the bed plate 3, between the ties l.

Mounted transversely of the frog block 28 is a bar 36 and this bar has apertured ends, one of which is pivotally connected to an actuating lever 37. The bar 36 extends through an opening provided therefor in the block 28, without interfering with the passages or grooves 31 and 32. Any suitable switch or signal mechanism can be employed for simultaneously shifting the frog block 28 with a switch tongue (not shown). rIhe bed plate 3 can be secured to the ties l and 2 by spikes 3S or other fastening means.

In Fig. 6 of the drawings there is illustrated an inner wear frog block 39, having a tongue 40 cooperating with the rails 7 in switching rolling stock. In lieu of the plate 34, I can use two gates 4l. These gates are hinged together, as at 42, beneath the frog block and each gate has a gutter 43 provided with a drain opening 44. The frog block is provided with depending keepers 45, and adapted to iit over these keepers are straps 46 carried by the outer edges of the gates. Extending through said straps and sait keepers are detachable rods 47, normally retained in place by nuts 4S. The rods 47 have handles 49 whereby they can be easily withdrawn to release the gates to deposit or dump the matter contained within the gutters 43.

In Fig. ll there is illustrated an angle stop that can be secured to the under side of the bed plate to extend upwardly through the slots 20, to limit the movement of a frog block. The angle stop can be made of various sizes whereby the frog block will have a desired amount of movement, and it is only necessary to change the angle stop when it is desired tochange the Athrow or movement of a frog block.

what I claim is 1. In a frog block, a bed plate adapted to support rails, al grooved block slidably mounted upon said plate between the rails, guide bars arranged transversely ot said block, straps carried by said bed plate for guiding said bars and having vertical portions interlocked with the edges of said bed plate, means arranged beneath said block to limit the movement thereof, and a bed plate arranged upon t-he underneath side of said bed plate and adapted to protect said means.

2. In a frog block, a bed plate, a'grooved block slidably mounted upon said bed plate, straps having vertical portions Ainterlocked with the edges of said bed plate, and means carried by said block and extending into said straps to guide saidblock in its movement upon said plate.

3. In a frog block, a bed plate, a grooved block slidably mounted upon said bed plate, straps having vertical portions interlocked with the edges of said bed plate, means carried by said block and extending into said straps to guideV said block in its movement upon said plate, and means `arranged beneath said block and -adapted to limit the movement of said block.

In testimony whereof I aiiiX my signature in the presence ot two witnesses. ANTHONY L. VISSAT.
