RAILWAY SWITCH Np ono'slsme. FROG.

citizen of the'United States, residing at Arcola, in the y'county of Douglas and State of Illinois, have invented certain new and useful Improvements in Railway Switch' and CrossingFrogs, of which the following is a specification. A

My invention relates to the joints or crossovers of railway rails, land particularly tothe @means for safely guiding the wheelon the tions taken through the rails respectively rails .at the frog points. The objects of the invention are, to provide a guard to engage the tread rim of the wheel while the tread runs on the rail as is customary; to provide v guards which will prevent the jumpin of the rail loose or broken wheels or roken iianges, increasingsafety in railway-crossings to provide maximum support for the tread of the wheels along 4the entire distance of the frogs; to providea guardy for the wheel upon both sides, and to generally improve the construction .and operation of railway frogs. Thescbiects and other advantages to hereinafter appear, I attain by means of the construction illustrated in 'a preferred form as 4 applied to an acute-angle crossing, in the accompanying drawing, wherein Figure 11s a plan view of the crossing, and Figures 2, 3, and' 4, are vertical cross secilong the lines (2) (3), and (4) of Figure 1. AIn the present practice in railway crossings it has been customary to rovide a guard `engaging the flange. of the w eel on the opposite side of the track from the frog, to pull the wheel over. vI find it much safer to provide a guard to enga e the rim of the tread of the wheel itself, an thus avoid the danger from sprung axles or loose wheels, the Wheel being itself directly guarded when it comesto the point of the crossing. The invention is applicable to all kinds of crossing points, whether they are rigid, spring-rail, or any street railway crossing, and it is of course applicable to any acute-anffle'frog or crossing.

In the' drawing it will e'flseen that the ordinary rails 5 .and 6 are shown coming to a point and spliced at 7, as is customary. l The (zo-operating portions of the rails, 8 and 9 ref spectively, are provided with a bend as shown, and-project forward in the parts 11 so as to run parallel with the point 7 on the two opposite sides, leaving room for the flange of the wheel, very much asis customary in suchdevices. For the guard rail, I use the Speccationvof Letters Patent. Applicant med August 24, 1905. serial No. 275,522.

than the rails 8, 9, and it runs parallel with the right hand portion of the frog, up past the point 7. From this point out, tliebottom flange of the rail 12 isY out olf,'as will be clearfrom Figure 3, and it is spliced-:and bolted to the web of the rail 8, which is also cut and continued beyond the oint 7 only in its web and flange, the head o the rail being cut off as will be clear from said figure. That'is, the rails 8 ,and 12 yrespectively are s liced together so that beyond the point 7 the head of the rail 12 is supported by the flange and web of the rail 8. yThe head of the rail 11 and part of the head of the rail 12 lie side by side for a certain distance as lvshown in Figure 3 and thus a support for the tread of the wheel is provided all the wa until the wheel comes upon the point 7 of he spliced rails 5 and 6. The flange 13 of rail 12 being removed to allow of-the head 14 .being supported upon the web and flange 10 of the rail 8. Usual fillerblocks 15 are used to connect and stiffen the-device and they are preferably bolted together with both side rail webs by means of bolts 16, or fastened toa bottoni late by means of ,rivets or a combination of both. The ends'of the guide rails 12 are al both ends planed off with a slant as shown at 17.

By this construction it will be seen that when the wheel comes in as indicated in Figi ure 1, moving toward the frog point, the rim of the wheel will be en aged directly by the guardY rail 12, and a ter passing the point marked by the line (4), both' the tread and the flange of the Wheel will bebonfined, and the tread is supported all along engaging the point 7 before it leaves the topjof the rail surface' l1, and continually keeping the side of the rim against the guard rail 12 until the flange has entirely come upon jhe rails 5 and 6 at the point 7 in the regular order. As the wheel does not depend at all oii the flan e of its mate to pull it over or hold; it in p ace, the Wheel is positively and firmliy7 confined to its position and safety supported throughout the crossing. Other advantages of the device will readilyoccui to inose familiar with the art.

Having thus described my invention an illustrated its use, what I claim as new, and

high rail 12, having a wider web and higher desire to secure by Letters Patent, is thefollowing:
