RAILWAY-FROG.

Specification of Letters Patent.

Patented July 2, 1907.

Application filed J'nne 18,1906. Serial No. 322,241.

To all lwhom it may concern:

Be it known that we, HARRY C. ODENKIRK and PHILLIP PFUNDsTEIN, both citizens of the United States, and both residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement inRailway-Frogs, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

Thisl invention relates to railway switches and frogs and their operating mechanism, and is designed to enable the switch and frog to be each jointly shifted so that whichever way the switch is set the frog will be correspondingly set to provide an unbroken track-way.

Our invention relates particularly to the hinging of the frog point, as hereinafter more fully described and delinitely set out in the claims.

ln the drawings, Figure l is a plan of our invention complete, the angle at which the siding leaves the main track being exaggerated for clearness; Fig. 2 is a cross section at the switch points as indicated by the lines a-a of Fig. Il; Fig. 3 is a cross section at the frog as indicated by the line b-b of Fig. l; Fig. 4 is a longitudinal section through the frog as indicated by the line c-c of Fig. l.

Referring to the parts by numerals, l represents the through rail of the main track; 2 andl 3 the other rail of the main track at opposite ends of the switch.

4 represents the through rail of the siding which at the switch merges with the rail 3. 5 represents the other rail of the siding.

The rails 2 and 5 are continued by the frog 6, which coperates with either rail' 7 or 8, from which lead the switch points 9 and l0 respectively. These switch points are coupled by a cross bar l1, which is connected by a link l2 with switch stand 13.

The description so Afar given applies to the usual split switch. ln our invention, however, the frog and the formation rails 7 and S are peculiar, as will now be described. I

Our frog instead of being spiked tothe ties is pivoted to the rails 2 and 5 as shown in the drawings. i We accomplish this by a steel casting l5, bolted to the rails 2 and 5, and a casting 1G, bolted to the frog. These two castings have overlapping ears as shown in Fig. 4, There is sufficient play between the frog and the rails 5 and 2 lto allow the frog to be shifted. This play is shown at ,lS in Fig. l. lf the frog were in the opposite position this play would betaken up and there would be space at 19 between the frog and the rail 5.

The point of the frog is shown as resting on metal plates 2l, on the ties 22. On the outer sides ofthe frog the rails 7 and are spiked in place to the ties. These rails extend alongside of the rog, being bent at an angle to make proper engagement with the frog, and then curve outwardly as shown at 24. Sutlicient space is provided between them so that whichever one the frog engages there is proper clearance for the wheel-{iange between Jthe other side of the frog and the rail. The 4two positions of the frog therefore provide a clear, continuous track for the main track or siding as desired.

The frog is coupled with the switch points and their operating mechanism by a link 26, secured to the under side of the frog between. the ties 22, a bell crank 27, on the outer side of the rail 2l, secured to this link, a bell crank 28, secured to the link ll, and a link 30, connecting the two bell cranks` The result of this connection is that when the switch point is shifted in one direction or the other the frog is correspondingly shifted so that it is impossible for the frog to stand in a different position from that at which the switch is set. Moreover, the switch stand which holds the switch points in place also, through the mechanism described, holds the frog in position.

Our mechanism has the advantage over the usual frog as well as spring frogs in that in our invention a continuous track is provided for both the main track and the siding and no guard rails are required. With the spring frog the rail corresponding to our rail 7 is :tree for a considerable distance adjacent to the frog to allow it to spring back for the siding trains. This is an element of danger for the main track. With our invention the two rails 7 and S are spiked tightly in place, the only free parts being the switch points and the frog, and these are held in position by the switch standand the connecting mechanism.

We claim:

In a railway switch and frog mechanism the combination of a shiitable frog point having two diverging rails, rails substantially alining with the frog 4point rails, a hinge comprised entirely within the V-shaped space provided by said rails and consisting of a member secured to the frog point rails, a member extending uninterruptcdly from one o1. the alincd rails to the other, and being' se:

cured to each of said rails, said rails overlapping one above the other. and a hinge pintle securing said meinbers together, substantially as described.

In testimony whereof, we hereunto allix our signatures in the presence of two Witnesses.
