b @ZZ whom it' may concern:

Be it known that we, FREDRIC C. WEIR and NATHANIEL O. (.roLDsMrri-i, of Cincinnati, in 1 the county oi? Hamilton and State of Ohio, have invented certain new and useful 1inproveinents in Railway-Frogs, of which the following is a speciiication.

The objeet of our invention is to eonstruet a frog of center-hearing girder-rails for street 4 railways in a Cheap, strong, and convenient manner.

The features ol our` il'nf'ention will be fully set forth in the description of the accompanying draw-ings, making a part of this specification, in whieh- Figure l is a top plan view. tion on line a it, Fig. l. Fig. tion ol' Fig.

AWe have shown the frog as constructed ot' center-hearing gi1'der-rails,hut these are the equivalentof sidehearing girder-rails.

The points are constructed as follows: A A represent girder-rails, which are beveled oft' to have their heads and flanges abut each other, as shown in Fig. The rails B B are Fig. 2 is a secis a modificahent to forni guard and main-traek rails in the usual manner of frogs. The said rails A A and B B are then secured t0 the base-plate D by rivets passing through the anges of said rails and through said plate, as shown in Fig. 2.

ln liig. o we have shown a modification, which com sts in bending the iianges 1 of rails A A upward and the flanges 2 of rails B B downward to overlap each other, insieid of 35 cutting oit one of the side trains, as shown in Fig. 2, and then securing the flanges 1 and 2 together hy rivets 3. This makes a very stron g structure and is the preferred form.

Tt is obvious that the iianges l Gould he de- 4o pressed and the lflanges 2 upset to overlap eaeh other reversely to the manner shown in Fig. 3, but such construction would he a mere change oi form.

'Having described our invention, what we 4.5

together by rivets 3 and t-he bottom flanges of 5o said rails secured to the base-plate D, suhstantially as specified.

In testimony whereof we have hereunto set our hands.
