FRIEDRICH NELLEN, OF ALDENRADE, GERMANY.
RAILWAY SWITCH PLATE.
SPECIFICATION forming part of Letters Patent N 0. 647,275, dated April 10, 1900.
Application filed November '7, 1898. Serial No. 695,686. (No model.)
To (0Z7, whom it may concern:
Be it known that I, FRIEDRICH NELLEN, a subject of the Emperor of Germany, residing at Aldenrade, Germany, have invented cer- 5 tain new and useful Improvements in Railway Switch-Plates, of which the following is a specification.
This invention relates to railways, and has more particular reference to a switch-plate to therefor, the object being to provide a plate which may be applied to the crossing of a single or multiple track and very advantageously serve as a substitute for the usual turn-plates employed for shunting the cars in anydirec- I 5 tion, which are very objectionable and adapted to allow the passage of but a limited number of cars at once, while myimproved switchplate allows the passage of any number of cars coupled together'. a, the passage of a com- 20 plete train.
In order that my invention be the more readily understood and carried into practical effect, I have illustrated two forms of same in the accompanying drawings, in which like let- 2 5 tcrs refer to like parts in both figures.
In the drawings, Figure 1 is a plan view of a switch-plate for a double main track having double side tracks. Fig. 2 is a crosssection of the double-track switch-plate on 0 line 2 2 of Fig. 1.
track rails, S S is the left-hand double side track. This switch-plate is also secured to the foundation of the track by means of bolts passing through holes 0 o 0, provided in the plate.
B B B are the check-rails of the main track and the side tracks, respectively.
0 C 0 indicate the pivoted switch-points.
K is a nose made one with the switch-plate A and again st which the central switch-points C are laid when the switch is set. The switchplate has suitable parts a. a a for the j unction of the main track S, the left-hand side track S, and the right-hand side track S respectively.
As shown in the drawings, the double track on the switch-plate is formed by three rails onlyt'. e., the two central rails are joined, by means of a'suitable cross-frog H near said switch-plate, and said rails are again separated by means of similar cross-frogs H H, located beyond said switch-plate.
Having fully described my invention, what Iyclaim, and desire to secure by Letters Patout, is
In a switch device, the combination with a plate having check-rails formed integrally therewith, of switch-points pivoted to the check-rails, means for joining the track-rails with the check-rails, and cross-frogs for joining the central rails of main and side tracks respectively, substantially as set forth.
FRIEDRICH NELLEN.
