IVIQVABLE-POINT CROSSING.

Specification of Letters Patent.

Patented June 8, 1909.

Application filed October 2, 1907. Serial No. 395,610.

To all whom it may concern: I

Be it known that I, WILLIAM M. HENDER- SON, a citizen of the United States, and resident of Steelton, Dauphin county, State of Pennsylvania, have invented certain new and useful Improvements in Movable-Point Crossings, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, of which Figure 1 is a plan view of a movable point crossing showing my invention applied thereto. Fig. 2 is an enlarged plan view, showing one of the movable point-rails embodying my invention. Fig. 3 is a section on the line oo, Fig. 2. Fig. 4: is a section 011 the line 00--m, Fig. 2. Fig. 5 is a section on the line g -y, Fig. 2. Fig. 6 is a section 011 the line zz, Fig. 2.

The object of this invention is to provide, in the point-rails of a movable point crossing, a hard-metal point which shall be reinforced throughout its entire length by the movable point-rail; thereby insuring greater strength and durability of construction than is ordinarily secured in point-rails of this general type. V

' The precise character of the invention will appear from. the following description:-In the drawings, 1 designates the main-track rails, bent to form the knuckle, 2, and 3 indicates the movable point-rails. From the point to some distance in the rear thereof, the head portion of the point-rail, 3, is removed, as seen in the drawings. A hard metal point-forming block or piece, 4, comprising a head portion, 4 and a web portion, 6, respectively, is inserted, constituting an extension of the said point-rail, 3. The upper or head portion of the hard metal or point-forming piece 4c abuts against the end of the head of the point rail; and the hard metal piece 4, adjacent the end of the head of the point rail, is made wider than the head of the point rail, and is extended toward the main rail and is adapted to engage the head thereof when the point-rail is moved toward the main rail. Said hard metal piece also extends rearwardly between the'point-rail and the main rail toward the heel of the pointrail, 3, forming an extension, 5, the top of which is flush with or in the same plane as the top of the point-rail, but having its rearward end downwardly beveled, at 7, as seen in Fig. 2, to form a pick-up for the false flanges of guttered wheels. The web portion, 6, of the hard-metal block, l, preferably extends beyond the end of the said extension, 5, and beneath the head of the point-rail, 3, as seen in Fig. 6. It will be observed that the pointforming block, 4:, is reinforced, throughout its entire length, by the web, 8, of the point rail 3, upon which web and the foot-flange, 10, the said wear-block is supported, being firmly secured to said web, at suitable intervals, by means of bolts, 9. By making the web, 8, of the point-rail, 3, continuous throughout the entire length of the movable point, a strong reinforcement and support is secured for the hard metal block, and the point of the rail, upon which the greatest amount of wear and strain come, is of much greater resistance and durability than would be the case were no such reinforcing and supporting means present.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a movable point crossing, the combination with a main rail of a movable pointrail having a portion of its head cut away, a hard metal point-forming piece abutting against the end of the head of the point-rail and having a tread portion wider than the head of the point-rail and extended toward the main rail, and means for securing the point-forming piece and the point-rail together.

2. In a movable point crossing, the com bination with a main rail of a movable pointrail having a portion of its head cut away, a hard metal point-forming piece abutting against the end of the head of the point-rail and having a portion wider than the head of the point-rail and extended toward the main rail, said point-forming piece having also a rearward extension flush with the top of the point-rail and located between the pointrail and the main rail, and means for securing the point-forming piece and the pointrail together.

3. In a movable point crossing, the combination with a main rail of a movable pointrail having a portion of its head cut away, a hard metal point-forming piece abutting against the end of the head of the point-rail and having a portion wider than the head of the point-rail and extended toward the main rail, said point-forming piece having also a rearward extension flush with the top of the point-rail and located between the point-rail and the main rail and having its rearward end beveled downwardly, and means for securing the point-forming piece and the point-rail together.

4:. In a movable point crossing, the combination with a main rail of a movable pointrail having a portion of its head cut away, leaving its base and web extending beyond its head; a hard metal point-forming piece abutting against the end of the head of the point-rail and having a portion resting upon the web of the point-rail and having a tread portion wider than the head of the pointrail and extended toward the main rail; and means for securing the point-forming piece and the point-rail together.

5. In a movable point crossing, the combination with a main rail of a movable pointrail having a portion of its head cut away, leaving its base and web extending beyond its head; a hard metal point-forming piece having a web engaging the side of the web of the point-rail toward the main rail, and a head abutting against the head of the point-rail and having a tread portion wider than the head of the point-rail and extended tovard the main rail; and means for securing the point forming piece and the point-rail together.

6. In a movable pointcrossing, the combination with a main rail of a movable pointrail having a portion of its head cut away, leaving its base and web extending beyond its head; a hard metal point-it'orniing piece having a web engaging the side of the web of the point-rail toward the main rail, and a head abutting against the head of the pointrail and lmving a portion wider than the head of the point-rail and extended toward the main rail; and a portion extended rearwardly of the end of the head of the pointrail and located between the point-rail and the main rail, and means for securing the point-forming piece and the point-rail together.

In testimony whereof, I have hereunto affixed my signature.
