SPECIFICATION forming part of Letters Patent No. 690,261, dated December 31, 1901.
Application filed .Tune 18, 1901. Serial No. 65,015. (No model.)
'To all whom. t may concern:
Be it known that we, JOHN C. FLINT andA MAURICE S. DEAN, citizens of the United States, and residents ot' Anaconda, in the county of Deerlodge and State of Montana, haveinvented certain new and useful Improvements in Switches, of which the following is a full, clear, and exact description.
The object of the invention is` to -provide certain new and useful improvements in switches, whereby the life of the switchpoint is greatly lengthened and when the switch is located on a curve the danger of the wheels climbing the switch-point is completely prevented.
The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.
A practical embodiment of the invention is represented in the accompanying' drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the views.
Figure 1 is a plan View of the improvement as applied, and Fig. 2 is an edge View of the head-rod.
The lead-rail A and the switch-rail B are connected with each other by rods C and D, of which the latter is the head-rod and is connected in the usual manner by a link E with the switch-changing mechanism for opening or closing the switch in thensual manner. The end of the lead-rail A terminates near the end of the guard-rail F,while the end B of the switch-railB is extended beyond the end of the leadrail A, so as to be located opposite a portion of the guard-rail F, asis plainlyindicated in Fig. l. This extension of the switch-rail B is connected by an extension rod D' with the head-rod D, said extensionrod D' being connected with a plate G, bolted to the extension of the switch-rail, and said extensionrod D is provided with a turnbuckle D2 for lengthening or shortening the extension-rod and allowing the trackman to properly adjust the extension or point B' of the switch-rail B to existing conditions of the track-rails. Now it is evident that by the arrangement described the extension of the switch-rail B is completely protected against injury from the car-wheels, as the guard-rail F will not allow the wheels to injure said extension. Furthermore, it is evident that when the switch is closed the carwheels are not liable to climb the switchpoint or go between the point-rail and the turnoutrail, thus avoiding wrecking the train. It is understood that by the guardrail F protecting the switch-point it is evident that the latter will last as long as the main rail, and consequently its lit'e is greatly increased over the ordinary switch-points as now used.
Having thus fully described our invention, we claim as new and desire to secure by Letters Patentl. A switch having a switch-rail, the point of which extends beyond the ends of the opposite lead-rail, the extending point being provided with a brace, as set forth.
2. A switch having a guard-rail, and an opposite switch-rail, the point of which eX- tends opposite the end portion of said guardrail, the extending point being provided with a brace, as set forth.
3. A switch having a switch-rail, the point of which extends beyond the ends of the opposite leadrail,and a head-rod for the switch and lead-rails and having an extension for connection with said extension-point, as Set forth.
4. A switch having a switch-rail, the point of which extends beyond the ends of the opposite lead-rail, a head-rod for the switch and lead-rails and having an extension for connection with said extension point, and a turnbuckle in said extension, for lengthening or shortening the same, as set forth.
5. A switch, comprising a switch-rail and lead-rail, of which the point of the switchrail extends beyond the lead-rail, and means for independently adjusting the said extending point in a lateral direction relatively to the body or remainder of said switch-rail.
