AI Technical Summary

Benefits of technology

"The invention is an assist rod assembly for a switch machine that includes front and rear baskets that play a dual role of taking up lost motion and actuating the assist rod. The front basket is connected to a torsional assist rod and rotates it when the switch is thrown. The rear basket has link arms that engage the assist rod and a slide block with nuts that can adjust the amount of lost motion before actuating the connector rod. The baskets are located in hollow ties to avoid interfering with tamping and the invention allows for a more compact switch assembly and a smaller number of components."

Problems solved by technology

Juxtaposing the switch machine and the assist rod would require unusually long ties to maintain the necessary clearance.
One disadvantage of prior art assist rod assemblies is that the basket is located between the rails to allow for tamping on the outside of the rails.
However, the location of the baskets between the rails results in limited accessibility due to hot air ducts used for snow removal that are frequently mounted between the rails over the top of the basket.
In the case of crowded rail yards, the loss of space resulting from adjacent switches becomes critical.

Embodiment Construction

[0031]FIG. 1 illustrates a fairly typical prior art switch layout in which the assist rod and basket assembly is shown. The switch is used to throw the switch point (rails 12, 14).

[0032] A switch machine 16 is mounted on the outside of the rails on a switch stand plate attached to the ends of elongated ties 18. Switch machine 16 actuates a throw rod 20 that is connected to a pair of switch rods 22, 24 connected end to end and extending between the points 26, 28 of the switch point rails.

[0033] A front basket 30 is disposed between the throw rod 20 and the switch rods 22, 24. As is known, the basket 30 is adapted to slide a predetermined amount along the throw rod 20 before the basket will engage so as to actuate movement of the switch rods. As will be appreciated by reference to FIG. 2, the predetermined amount may be adjusted in the field by displacing basket nuts 31, 33 that are engaged on a threaded portion of the throw rod 20.

[0034] The switch may also include ancillary roddi...

Abstract

A railroad switch assembly comprises a basket that directly actuates a torsional assist rod. The basket is located at a lower elevation than the assist rod, preferably in a hollow tie and preferably between the switch machine and the running rail.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application is a Divisional of U.S. patent application Ser. No. 10 / 697,855, which is a Divisional of U.S.patent application Ser. No. 10 / 314,774, now issued as U.S. Pat. No. 6,688,560, which is a Continuation of U.S. patent application Ser. No. 09 / 944,748, now issued as U.S. Pat. No. 6,543,727.TECHNICAL FIELD OF THE INVENTION [0002] This invention relates to assist rod assemblies for throwing railway switch points. BACKGROUND OF THE INVENTION [0003] Railway switches generally include a switch machine mounted on the outside of the rails adjacent the turnout points. The switch machine actuates a throw rod that is connected to a switch rod extending between the switch points. [0004] A lost motion device, commonly referred to as a basket, may be provided between the throw rod and the switch rods to take up some of the motion of the throw rod before transmitting it to the switch rods. The basket enables a signal maintainer to adjust both...
