Both the pointed rail D and the outside elevating-rail D being at their free or outer end level with the main-track rails A and A and continuing for some distance level with them-that is to say, from the line 5 5 to the line 6 6, at which latter place they both commence to incline upwardit is evident that the passage of car-wheels from the main track to the siding and from the siding to the main track will be accomplished more smoothly and satisfactorily than if the switch-rails terminated at the line 6 6. By means of this level prolongation of the switch-rails D and D the wheels on both sides, respectively, of the car will bear vertically upon the switch-rail and also upon the main rail from the line 5 5 to the line 6 6. This takes place whether the car is entering or leaving the switch, and the transition of the vertical bearing of the carwheels from the switch-rails to the maintrack rails, and vice versa, is thereby made in a most excellent manner. This vertical bearing of the car-wheels on both sets of rails at the line 5 5 and at the line 6 6 and between these lines is shown in Figs. 5 and 6.

Instead of making a vertical angle in the switch-rails at the line 6 6, where they begin to incline upward, it is preferable to use there an easy vertical curve, as shown in Figs. 8 and 9, so that when the car-wheels enter upon or leave the inclined portion of the switchrails the change in their movement will be very gradually made.

I claim as my in vention- 1. The combination in a railroad-switch, of the unbroken main-track rails, the rails of the siding or turnout and a movable switch structure consisting of an outside inclined elevating-rail and an inclined pointed rail with a guard-rail attached to it and movable with it, the upper surface of the pointed rail, for a portion of its length adjoining its free end, being level with the upper surface of the maintrack rails, and the free end of the pointed rail extending beyond the inclined portion of the outside elevating-rail, whereby the said pointed rail will direct the wheels of a car laterally so that the wheels on the side opposite the pointed rail will be forced to more fully overlap the outside elevating-rail, before any actual elevation of the said wheels takes place, substantially asidescribed.

2. The combination-in a railroad-switch, of the unbroken main-track rails, the rails of the siding or turnout and a movable switch structure consisting of an outside inclined elevating-rail and an inclined pointed rail with a guard-rail attached to it and movable with it, the upper surface of each of the two switchrails, for a portion of its length adjoining its free end, being level with the upper surface of the main-track rails, and the free end of the pointed rail extending beyond the inclined portion of the outside elevating-rail, whereby the said pointed rail will direct the wheels of a car laterally so that the wheels on the side opposite the pointed rail will be forced to more fully overlap the outside elevating-rail, before any actual elevation of the said wheels takes place, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
