OF HIGH SPIRE, PENNSYLVANIA, ASSIGNOR TO THE PENNSYLVANIA STEEL COMPANY, OF PHILADELPHIA, PENNSYL- VANIA, A CORPORATION OF PENNSYLVANIA.

Specification of Letters Patent.

Patented March 5, 1907.

Application filed June 26,1906. Serial No. 323.424.

T0 all whom, it may concern: I l l Be it known that I, VVILLIAM M. HENDER- SON, a citizen of the United States, residing in the town of High Spire, in the county of Dauphin and State of Pennsylvania, have in vented 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. 2 is an enlarged plan view showing one of the movable-point rails embodying my invention. Fig. 3 is a section on line I i) '0, Fig. 2. Fig. 4 is a section on line at x,

I l l r Fig. 2. Fig. 5 is a section on line y y, Fig. 2. Fig. 6 is a section on line 2 2, Fig. 2. Fig. 7is an elevation taken on line a a, Fig. 1.

The object of this invention is to provide the point-rails of a movable-point crossing with a hard-metal point of unique construc tion and at the same time to provide said I point-rails with a suitable pick-up device for I guttered wheels, which pickup device shall I be integral with the hard-metal point portion.

The precise character of the invention will appear from the following description.

In the drawings, 1 designates the usual main-track rails bent to form the knuckle l designates the movable rails, each of which in this instance terminates some distance to the rear of said knuckle, as seen in Figs. 1 and 2. A hard-metal point-forming piece 4 constitutes an extension of the said point-rail 3 and has extending on the outer side and to the rear end of the said point-rail an extension 5, the to of the head of which I is in the same plane as the head of the pointrail, but its outer end is at 6, as seen in Fig. 2. The web portion 7 of p the extension 5 abuts against the web of the l point-rail 3 and extends for this purpose beyond the end of said extension 5 and beneath l the head of the point-rail 3, as seen in Fig. 6. The said web portion 7 is continuous with the web portion 7 of the hard-metal pointpiece in advance of the end of the point-rail. Extending from the point of said pointl forming piece and lying against the web 7 l thereof throughout its length and then 1 against the web of the point-rail 3 to a point opposite the end of the web extension 7 is a l beveled downwardly I rolled-steel strap-piece 8. Said strap-piece is secured to the web 7 of the point-forming piece by bolts 9, passing through the web 7 and through said strap-piece, as seen, and the strap 8, point-rail 3, and hard-metal piece 4 are secured together by bolts 10 passing through the strap 8, the web of the point-rail, and the web extension 7 of the said hard-metal piece, thus firmly securing the said hard-n1etal piece, point, and strap together. The strap-piece 8 is also provided with a foot-flange 11, to which may be attached the usual switch-bars 12, thus avoiding the attachment of said bars 12 to the hard-metal piece 4., said hard-metal piece being usually of cast metal.

By making the point portion of the pointrails 3 of hard metal the breaking down of the point under the hammer-blows of passing wheels is avoided, and by providing the heac extension 5 with its beveled portion 6 on the outer side of the point-rails 3 if a wheel passing over the point-rail should be gutteredthat is, have a false flange on its outer side said false flange will ride up the inclined portion 6 onto the head extension 5, and so be uplifted to the plane of the head oi the trackrails 1, over which it will pass without wearing a groove therein, as would otherwise be the case.

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 the knuckle-forming trackrail, of the movable-point rails, terminating some distance on each side of the knuckle, the hard-metal point-forming piece, whose upper surface is in the same plane as the said point-rail, said point-forming piece having the rearward extension adjacent the outer edge of the head of the point-rail; together with means for securing said point-rail and hard-metal point-forming piece together, substantially as set forth.

2. In a movable-point crossing, the combination, with the knuckle-Forming trackrail, oi? the movable-point rails, terminating some distance on each side of the knuckle, the hard-metal point-forming piece whose upper surface is in the same plane as the said point-rail, said point-forming piece having the rearward extension adjacent the outer edge of the head of the point-rail, and whose free rear end is downwardly beveled; together with means for securing said pointrail and hard-metal point-forming piece together, substantially as set forth.

3. In a movable-point crossing, the combination, with the knuckleiorniing trackrail, of the movable-point rails, terminating some distance on each side of the knuckle, the hard-metal point-forming piece, whose upper surface is in the same plane as the said point-rail, said point-forming piece having the rearward extension adjacent the outer edge of the head of the point-rail, and having also a web portion, together with the strappiece extending the length of the point-for1ning piece, its forward portion lying against the web of the latter, and its rear portion against the web of the point-rail; together with the bolts securing saidpoint-forining piece, point-rail, and strap, together, substant ally as set forth.

4. In a movable-point crossing, the combination, with the knuckle-forming trackrail, of the movable-point rails, terminating some distance on each side of the knuckle, the hard-metal. point-forming piece, whose upper surface is in the same plane as the said l pointrail, said point-forming piece having the rearward extension adjacent the outer edge of the head of the point-rail, and having also a web portion together with the strappiece extending the length of the point-forming piece, its forward portion lying against the web of the latter, and its rear portion against the web of the point-rail; the foot extension of said strap-piece; together with the bolts securing said pointfor1ning piece, point-rail, and strap together, substantially as set forth.

In testimony whereof I have hereunto affixed my signature.
