Application filed January 19, 1918. Serial No. 212,754.
To all whom t may concern:
Be it known that I, BENJAMIN B. Bn'r'rs, a citizen of the United States, and resident of St. Louis, State of Missouri, have invented new and useful Improvements in Railway-Frogs, of which the following is a specification containing a full, clear, and exact description, reference being had to the accom anying drawings, forming a part thereof.
My invention relates to certain new and useful improvements in railway frogs which has for its special object the employment of a pivoted frog point, which is controlled in its movement b a guard lever or tongue, which is operate by the movement of the rolling stock.
In the drawings,
Figure 1 is a top plan view of my invention.
Fig. 2 is a bottom plan view of the same.
Fig. 3 is an A'end View looking in the direction of the arrow 3 in Fig. 1.
Fig. 4 is a longitudinal section taken on a line 4-4 of Fig. 3 looking in the direction of the arrow.
Fig. 5 is a bottom plan view of the pivoted frog point.
Fig. 6 is a longitudinal section of the same taken on a line 6-6 of Fig. 5.
Fig. 7 is a transverse section taken on a line 7--7 of Fig. 5 looking in the direction of the arrow.
Fig. 8 is atop plan view showing a slightly modified form of my invention.
Fig. 9 is a bottom plan view of a pivoted controlling guard lever or tongue for operating the frog point.
F 1g. 10 is a top plan View of a modled form of my invention showing the same built up out of pressed steel.
Fig. 11 is a bottom plan view of the housv ing which carries the guard and lever mechan1sm.
Fig. 12 is a sectional view looking 1n the direction of arrow taken on a line 12-12 of Fig. 10.
Fig. 13 is a bottom plan view of the frog point which I employ in the modified form of my invention.
Fig. 14 is a side elevation of the same, and Fi 15 is a section taken on a line 15-15 of Flg. 1, looking in the direction of the arrow.
Referring to the drawings, Fig. 1, which shows my invention cast 1n one piece, 16 indicates what might be termed a base plate, which is provided throughout with a series of spike openings 17. Cast integral with the base plate 16 is an elevated plate or portion 18, and formed integral with the plate 18 are guards 19, located at one end of the frog, and located at the other end are continuations 20 of the rail ends 21.
Formed on the opposite end of the frog are the rail ends 22. To the rail ends 22 and 21 rails may be secured by iisli plates in the ordinary manner.
23 indicates the movable pivoted frog point provided on one end with a stud 24 which is mounted in a suitable `opening 25, formed in the elevated seat 18 and is secured therein by means of a cotter in 26.
Secured intermediate of tie ends of the frog point 23 is an integral stud 27 which is mounted in an elongated opening or slot 28,formed in the elevated seat 18 and rojects downwardly through the same. gutwardly projecting on each side of the stud 27 is a cover plate or flange 29a which is adapted to cover the opening 28 to prevent the access of dirt, snow or any foreign substance into the opening 28 and thereby interfere with the operation of the frog point.
The forward end of the frog point 23 is provided with recesses or pockets 30 for the accumulation of any substance that might be lodged around the end of the frog point or in its seats.
As shown in Fig. 1 the frog point is rounded at 31 so as to fit the rounded recess or depression 32 formed in the rail extensions 20. Mounted between the rail extensions 20 is a guard point or tongue 33, which has secured to its under surface a stud 34 which is mounted in an opening 35 of the elevated seat 18 and is also provided with another' stud 36 mounted in an elongated opening 37. The stud 34 is secured in place by means of a cotter pin 38. Mounted on the stud 36 and secured `thereto by means of a Cotter pin 39 is one end of a lever 40, said lever being mounted on a stud or bearing 41 and secured thereon by means of a Cotter pin 42. The opposite end of the lever 40 is pivotally mounted on the stud 27 of the frog point 23. The lever 40 forms a connection between the frog point 23 and atethefrog point in the opposite direction,
the guardlever or tongue 33 whereby the movement of either one will transmit motion through said lever to the other in the oposite direction; that is to say, if the lever 33 is operated in one direction by the flange of the car wheels such movement will oper` the ends of the rail extensions 20 andthe guards 19, however, if desired this space may be filled out by a guard`43 connecting the same as illustrated in Fig. 8.
In Figs. 1, 2, 4 and 8 I have shown theV frog cast integral.` When so made it is of a hollow formation and is provided with strengthening ribs 44. j 'Y In Figs. 10 and 11.1 have shown my improved frog made of pressed steel, in which construction I use a base plate 45 and a top plate or housing 46. These two may be riveted together or fastened together by means of spikes passing through the spike openings 47 and 48.
the guards 19 are rivetedl to thevhousing as well as the rail extensions 20 and 22. This construction is practically the same as whenV 1. A railway frog comprising a base, a
frog point pivotally mounted on lthe top thereof, guards carriedby the base and dis- Y posed on each side of the frog point adjacent its connection to the base, a guard lever pivotally secured to said base, a guard secured to said base on` each side of said guard lever, said guards being provided with seats to receive the end of the frogpoint Vwhen thrown inoperative position, and a lever connection between the frog point and guard lever whereby the operation of one in a given direction will cause the other to l be operated in an opposite direction.
2. A railway frogV comprising' a base plate, a housing secured thereto, a'pivoted frog point mounted on the housing, guards mounted on each side of the frog point adjacent its point of pivotal connection, a guard lever carried by the frog, a guard and rail extension mounted on each side of the guard lever and .provided with a seat to receive Athe end of the frog point, a lever connection Abetween the frog point and guard lever whereby, when the frog point is moved in one direction, the guard lever will be. thrown in the opposite direction and vice versa.
3. A railway frog comprising a base'plate provided with an elevated seat andl spike openings, rail ends secured to the frog at one end, rail ends and rail extensionsprovided with seats for theV frog point securedtothe opposite end of the frog, guards carried by the frog adjacent one end thereof, a' pivoted frog point located between the guards, av
pivoted guard tongue or lever mounted between the rail extensions, and a connection between the frog point and guard tongue whereby the movement of one will cause theV other to move in theopposite direction. Y
4. A railway frog comprising a base or support, rail ends' carried by one endofthe base, guards carried by said end ofthe base, a pivoted frog point having one end pivoted between the guards, rail sections i Y carried by the opposite end of the base pro- When my frog is made out of pressed steel vided in their inner' erids with va recess in which the' free end of thefrog Apoint is adapted to be seated, a guard' toiigueor lever pivoted between the rail sections, and` a lever pivoted to `the baseand having `one` end pivoted to the frog point and itsvopposite end pivoted to the guard lever whereby'upon the' operation of either thefrog' point or guard lever the other will be'o'perated'in the opposite direction.
5. In a railway frog', a pivoted frogpoint, guards positioned on each side of said frog point adjacent its pivoted end, the said frog point Vbeing provided on its free end with recesses, a guard lever adapted to be operated by the movement of the wheel; flange,
and aV connection between said frog point and lever whereby thev operationA of one will cause the other to be operated in the opposite direction. f
Y 6. In a railway frog, .a cast frogpoint provided at one end with a pivotv stud; and
t intermediate its ends with a studjandV intermedi'ate of its ends with transverse ribs. Y
7. In a railway frog, a cast 'frog `point provided with a pivot stud and a stud spaced apart from the pivot" stud, and on'each side of its sides adjacent said last mentioned stud, with a lateral flange. i
8, A railway frog comprising, a base plate, a pivoted Vfrog point mounted thereon, rail sections secured to the frog 'and adjacent said frog point, a guard secured'on each side of said frog point, rail ends and rail extensions secured to the opposite end of the frog, a guard lever pivoted between said rail extensions, the said rail extensions and first mentioned guards being spaced apart and the said frog point spanning the space between tbe rail ends and rail extensions and answering as a running rail between the two, and a connection between the end of the frog point and base for limiting the lateral 10 throw of the same.
